    PYROLYSIS FEEDER
    The invention relates to a pyrolysis device feeding device according to the preamble of claim 1.
    A pyrolysis device is used to treat crushed waste material such as plastic and / or rubber waste by pyrolysis. Pyrolysis, or dry distillation, is a chemical reaction in which organic solids are decomposed by heating oxygen without affecting the process. Pyrolysis is usually carried out using either a vacuum in the case of vacuum pyrolysis or an inert atmosphere such as nitrogen to displace the air with oxygen. Industrial pyrolysis reactions are generally carried out at a temperature of 300 to 700 ° C.
    In the pyrolysis device, waste containing hydrocarbons, for example plastic and / or rubber, is treated in such a way that the process mainly produces oil, coal and gas. According to the known method, the plastic and / or rubber waste is crushed and the crushed material is placed in a pyrolysis chamber. The chamber is locked airtight by an air lock, which is also usually a barrier for the material to be treated.
    According to the known solution, the feeding device of the pyrolysis device is, for example, an inclined conveyor or a screw conveyor, the lower part of which is in a liquid in a liquid pool, such as oil. The liquid then forms an air trap to prevent air from entering the reactor. The material to be fed to the pyrolysis device is led to a lair, which at the same time forms a liquid pool. An inclined conveyor lifts the material up from the fluid in the bar. From the top end of the bump conveyor, the material falls into the pyrolysis reactor.
    One problem with the known feeders is that the feeder oil is transported with the feed material to the pyrolysis device. Oil displacement can be reduced by means of grooves on the oblique surface of the bump conveyor which allow the oil to drain back into the liquid pool. The feeder collision conveyor may also include a timer that sequentially initiates and stops the conveyor's progressive movement so that changes in movement cause at least a portion of the fluid carried to fall into the conveyor groove and flow back into the feeder fluid.
    Another problem with known feeders is that the particles fed to the pyrolysis device must be crushed sufficiently small. The particle size of the feeders commonly used in feeders should generally be less than 9 mm. If for some reason too large particles are left in the feed particles, they may cause problems in the feeder. The feeder may also become clogged.
    It is an object of the present invention to provide a novel pyrolysis device feeder which does not have the drawbacks described above. The pyrolysis device feed unit according to the invention is characterized in what is stated in the characterizing part of claim 1.
    According to the invention, the feeding device of the pyrolysis device comprises a feed chamber with genital organs through which the crushed material, such as plastic and / or rubber waste, is introduced into the pyrolysis chamber. The feed chamber of the feeder and the size of its genitalia can be dimensioned so that the size of the feed material does not cause problems and the material proceeds without problems to the pyrolysis chamber of the pyrolysis device. In this case, the feed particles do not need to be crushed into small particles, as in the known feeders, where the feed particles can generally be up to 9 mm in size. If the feed particles are not very large, the crushing step can also be omitted completely.
    Another advantage of the feeder according to the invention is that it can also be fed with material which cannot be fed to the known feeders. Such materials include floating and porous materials that do not pass through known feeders.
    The feeder according to the invention can be connected to any pyrolysis device, whereby an efficient feeder makes the pyrolysis device more efficient. The feed device according to the invention may be located above the pyrolysis reactor, whereby the feed material falls directly from the feed device into the pyrolysis chamber of the pyrolysis device. More preferably, however, the feeder is located below or at the side of the pyrolysis reactor since the feeder is not heated by the hot pyrolysis chamber. There is then a gas-tight conveyor between the feeder and the pyrolysis reactor which transfers the feed material from the feeder to the pyrolysis reactor. Most preferably, the feeder is located below the pyrolysis reactor, whereby the hot steam of the pyrolysis chamber also cannot enter the feeder.
    According to the invention, the material to be treated in the pyrolysis device, such as plastic and / or rubber waste, is fed into the pyrolysis chamber of the pyrolysis device by a feeder having a material inlet, a delivery chamber, A vacuum pump for a pyrolysis device to provide a vacuum or sufficient vacuum is known in the art.
    In order to seal the feed device according to the invention, the gland member of the feed chamber connected to the feed opening of the feed device includes a gate valve with a seal. The second genital member of the feed chamber includes a closure plate which is pressable against the end of the feed chamber. The feed chamber is in communication with the discharge chamber of the feeder when the shutter plate of the feeder is open. According to the invention, a discharge means is provided in connection with the feed chamber of the feed device for transferring material from the feed chamber to the discharge chamber of the feeder, from which the material is led through the discharge chamber of the discharge chamber to the pyrolysis chamber.
    The pyrolysis device feeder may be located above the pyrolysis chamber of the pyrolysis device, whereby the material to be treated can be dropped through the discharge opening into the pyrolysis chamber. When the pyrolysis device feeder is located below or on the side of the pyrolysis chamber pyrolysis chamber, a gas-tight conveyor is connected to the feeder to transfer the feed material from the feeder to the pyrolysis chamber.
    The invention will now be described by way of example with reference to the accompanying drawings, in which
    Figure 1 illustrates a pyrolysis device feed device according to the invention in a material feed situation.
    Figure 2 shows the feeder with the feed chamber closed.
    Figure 3 shows the feeder with the drain member open.
    Figure 4 illustrates a feeder in a material unloading situation.
    Figure 5 shows a feed device according to the invention mounted in a pyrolysis device above the pyrolysis chamber.
    Figure 6 shows a feed device mounted on a pyrolysis device below the pyrolysis chamber.
    Fig. 1 illustrates a pyrolysis device feeding device 10 according to the invention including an inlet 11, a closure member 14, an inlet chamber 20, an outlet member 30, an outlet member 40, a discharge member 50 and a discharge port 41. In FIG. with the inlet 11 open. In this case, the feed material 12 can be fed through the feed opening 11 to the feed device 10, where the feed material 12 falls to the bottom of the feed chamber 20.
    Thereafter, the piston 18 of the cylinder 17 of the genus 14 pushes the slide valve 15 to the left in Figure 1, whereby the slide valve 15 closes the inlet 11 as shown in Figure 2.
    The gate valve gasket 16 in the inlet 11 seals the gate valve 15 in the walls of the inlet 11 so that the inlet 11 leading to the inlet chamber 20 is sealed. In Fig. 2, the feed chamber 20 is then completely closed because, in addition to the feed opening 11, the left end of the feed chamber 20 is also sealed by the closing plate 51 of the drain member 50 which is pressed against the end of the feed chamber 20. To ensure sealing, the sealing plate 51 may be provided with a seal.
    When the supply chamber 20 is closed, the valve 23 of the conduit 22 leading to the vacuum pump 21 is opened, whereupon the vacuum pump 21 begins to suck. The generation of vacuum in the feed chamber 20 is monitored by a sensor 24 or meter connected to the feed chamber 20. Vacuum generation can also be monitored by an automation device.
    When the vacuum or vacuum in the feed chamber 20 has reached the desired value, the piston 53 of the cylinder 52 of the drain member 50 pulls the shut-off plate 51 from the end of the feed chamber 20 to the position on the left edge of the discharge chamber 40. The passage from the feed chamber 20 to the discharge chamber 40 is then open and the feed chamber 20 and the discharge chamber 40 are interconnected. The discharge chamber 40 is also in communication with the pyrolysis chamber of the pyrolysis device.
    Subsequently, the piston 33 of the cylinder 32 of the discharge member 30 pushes the pusher plate 31 as shown in Figure 4, whereby the material 12 fed to the supply chamber 20 falls into the discharge port 41 located in the discharge chamber 40. If it is not possible to drop the material into the pyrolysis chamber, at least one conveyor may be provided between the feeder and the pyrolysis chamber.
    When the material 12 fed to the pyrolysis device feeder 10 is transferred to the pyrolysis chamber pyrolysis chamber as described above, the plunger 33 of the cylinder 32 of the discharge member 30 retracts the pusher plate 31 to the right in FIG. Correspondingly, the piston 53 of the cylinder 52 of the discharge element 50 pushes the shutter plate 51 against the end of the supply chamber 20, sealing the supply chamber 20. The piston 18 of the cylinder 17 of the closing member 14 pulls the slide valve 15 out of the inlet 11. Hereby the material 12 to be fed can again be fed from the inlet 11 into the feeding chamber 20 and the above-described process starts from the beginning.
    Figure 5 shows a feed device 10 according to the invention mounted on a pyrolysis device 60. In this case, the feeding device 10 is above the pyrolysis device 60 so that the material to be fed falls from the discharge opening 41 of the feeding unit 10 into the pyrolysis chamber 61 of the pyrolysis device 60. Fig. 5 does not describe the pyrolysis device 60 in more detail.
    Fig. 6 shows a feeding device 10 according to the invention mounted on a pyrolysis device
    60 so that it is below the pyrolysis chamber 61. Since the material to be fed to the pyrolysis device 60 in this solution cannot be dropped directly into the pyrolysis chamber 61, a gas-tight conveyor 62 is disposed between the feeder 10 and the pyrolysis chamber 61. .
