    专利说明:

    The invention relates to the production of ice, namely to devices for the preparation of transparent small ice ice.
    A device for producing small ice ice is known, which contains ice molds placed one next to the other without gaps and installed in thermal contact with an evaporator. The device is equipped with a plastic shield, which during the freezing cycle is pressed down to the forms, so that ice can only grow in forms. Water is supplied to the mold through a nozzle. A bath is installed under the molds, communicated through a pump with a nozzle. When the nozzle is in operation, it becomes clogged with contaminants and minerals in the water. Once the ice pieces have reached their final size, the plastic shield and the water bath are discharged. Since the shield is frozen into ice pieces, a strong drive is necessary. Effluent residual water is collected and discharged. Pieces of ice fall into the bunker themselves.
    A disadvantage of this device is that it requires too much space so that the bath and the plastic shield can be freely rotated. This space is several times the volume of the bath.
    A device for preparing transparent small ice ice is known, which contains an evaporator having forms for ice, open from the bottom base, and having a thermal contact with the refrigerant pipes connected to the refrigerant circuit, interposing elements made of insulating material between the forms / made in the form of plates. or strips, a defrosting device, a bath for water with inlet and outlet nozzles located below the evaporator molds and a mechanical sprayer for supplying water from the bath to the rmy.
    In this device, the nebulizer is a nozzle that is prone to clogging. In addition, it is not envisaged to prevent the formation of an ice field between forms and the ice does not thaw in a timely manner. Therefore, the forms must be located at a certain distance from one another.
    The purpose of the invention is to reduce the size of the device.
    Figure 1 shows the evaporator section; figure 2 - the lower side of the evaporator, the plan; Fig. 3 is a schematic of the device for obtaining transparent ice, side view; 4 is a side view of the locking device for the water bath; Fig. 5 is a schematic diagram of the pipelines for the refrigerant and the hot gas.
    The device for preparing transparent small ice ice contains an evaporator having forms 1 for ice, open on the bottom base side, and having a thermal contact between the refrigerant pipes 2 and the heat contact with them. Between Forms 1
    0 placed overlapping elements 3 of insulating material, made in the form of plates or strips and installed so that the water sprayed under pressure could not get on the back side
    5 forms 1. As an insulating material for the overlapping elements 3, polyethylene, polyamide or polyvinyl chloride are used.
    The device contains a device
    0 for thawing and a bath 4 for water located under the forms 1 of the inlet and outlet nozzles 5 and b, on which the solenoid valves 7 and 8 are installed, and the mechanical sprayer 9 for the inlet
    5 water from the bath 4 in the form 1. The defrosting device is located on the surface of the overlapping elements 3 facing the bath 4, installed with a gap to the edges of the lower base of the forms 1 and contains
    0 heating elements, which are pipes 10 for hot gas, and metal panels 11 installed to ensure thermal contact with them, which pass through covering the transverse
    5 section forms 1.
    In this case, forms 1 are octagonal, respectively, pieces of ice are also octagonal. Forms 1 may have a different form and
    0 wish pieces of ice can be round,
    oval, hexagonal, square
    or any other section, as well as in
     hemispheres, pyramids, cones, rings, and
    etc.
    5 The refrigeration circuit includes a compressor 12, a condenser 13, an expansion valve 14 and pipes 2 which are included in the evaporator and connected to valve 14 by a pipe 15. The pipes 10 for hot gas,
    0, intended for defrosting, are connected to the refrigeration circuit after compressor 1.2 before the refrigerant pipes 10 entering the evaporator through pipes 16 and gas valve 17.
    5 Mechanical spray 9 dl under-. The water from the bath 4 to the mold 1 contains at least one rotatable impeller mounted on the horizontal shaft 18c immersed in the water in bath 4.
    The impeller consists of two parallel discs 19, between which at least one and maybe two concavely curved blades 20 are mounted. If there are more than four rows of forms 1 in the evaporator, then several sprayers 9 are placed in the bath 4 or sprayers 9 are moved under the evaporator on the carriage.
    In the bath 4, under the spray 9, there is an overlap 21 in the form of a shield with longitudinal slots or lattices, which does not prevent water from splashing up into forms 1, but prevents pieces of ice 22 from falling into the bath 4 or onto the spray 9 during thawing. Pieces of ice 22 are served in a bunker located under bath 4.
    The enclosing walls of the bath 4 ensure that the unfrozen water returns to the bath again. The guard also serves as a movable damper 23, which, after sending excess water back into the bath 4, does not prevent the passage of ice cubes 22. On the discharge pipe 6 there is a siphon 24, fixed with the provision of thermal contact with the pipeline 15.
    The device works as follows.
    The refrigerant is compressed in the compressor 12, compressed in the condenser 13, and through the pipeline enters the expansion valve 14, which is cooled to approximately -15 ° C. The refrigerant in this case passes through the pipeline 15 and the pipes 2, is again sucked in by the compressor 12 and compressed. The valve 17 in front of the pipes 10 of the hot gas is shut off.
    : Forms .1 in contact with pipes 2 are cooled. The curved blade 20 of the impeller spray 9 captures a large amount of water from the bath 4. Thanks to the combined action of both discs 19 and the spraying blade, water can be oriented to the shapes 1 for freezing. The water level in the bath can not be controlled. When injected; water from below, it freezes in the form of transparent pieces of ice. At the same time, the sprayed water heats the metal panels 11 and the pipes 10, therefore, the formation of undesirable ice buildup between forms 1 is prevented or significantly slowed down.
    Flawlessly clear pieces of ice are formed if water is sprayed into the molds at intervals. The duration of these intervals can be 15-20 seconds. In this case, it takes some time to turn a certain amount of water into ice. In the siphon 24 of the discharge pipe 6, having contact with the pipeline 15, ice is formed on the plug.
    As soon as the pieces of ice in the forms 1 reach the required size, the gas valve 17 opens. Hot gas from the compressor 12 through the pipeline 16 turns the valve 17 into the pipes 10 and further through the pipeline 15 into the pipes 2 for the refrigerant having thermal contact with Forms 1.
    0 Due to the low thermal inertia of pipes 10 and metal panels 11 and due to thermal insulation by means of overlapping elements 3, possible ice frost between forms 1 melts, after which
    5 pieces of ice fall out of the form 1. Due to the passage of hot gas through the pipeline 15, ice is melting on the cork in the siphon 24 of the nozzle 6, with the result that the bath 4 can be emptied. Since the cross section of the siphon
    0 24 is much larger than the cross section of the valve 8, and since the siphon 24 does not contain moving parts, it has great operational reliability.
    Overlap 21 in the form of a shield or lattice
    5 prevents 4 pieces of ice 22 from falling out of forms 1 from falling into the bath when they are thawed. The water from bath 4 is sprayed into the mold
    unhindered. The shield or lattice is mounted obliquely, so the pieces of ice 22 under their own weight roll into the bunker,
    In the proposed device, the implementation of the defrosting device with pipes 5 for hot gas and metal panels 11 placed between the open ends of the forms 1 prevents the pieces of ice from freezing, the sprayer 9 with rotating blades
    0 is extremely reliable, durable and very simple, and due to the shape of the blades 20, the amount of water, the width of the spray area and the direction of spraying can be controlled. The whole node is
    5 compact and provides high freezing performance. Pieces of ice are transparent.
    Forms for freezing can be located adjacent to each other on such
    0 distance to allow enough space for the defrosting device. Consequently, the production capacity of the evaporator is very high, and the dimensions of the device are reduced.
