    For underground use, a dust filter (30) is provided, the housing (1) of which is designed as a unit which can be transported and connected to further housings and is fitted with removable filter pockets (17) which have a frame (17'), making a seal against the housing (1), with the grids (19) covered with filter cloth (20) and spacer shoes (18) holding these apart. The housing (1) as such has, on each of the two sides, inspection openings (3, 4) which can be operated selectively, and pure gas and raw gas channels (5, 6) located on the upper side. These channels (5, 6) are provided in the end with couplable head pieces (12, 13) so that connecting is easy when housings (1) are arranged in a row. The raw gas channel (6) is in each case connected to the interior (29) of the housing via perforations (15) formed in the bottom (6') of the channel, while the pure gas channel (5) is in turn connected to the interior of the housing (1) via a channel (16) running along the front of the housing (1). By arranging individual modules in a row, a dust filter (30) of virtually any desired capacity can thus be provided, each individual module being suitable for safe transport on the equipment available underground, namely in the state prefabricated above ground. Stable support for the filter cloth walls is provided by the grid (19) which consists of longitudinal and transverse wires (21, 32, 33, 34) in an arrangement bent at right angles.

    专利说明:

    The invention relates to a dust filter for use in underground mining and in tunneling, in particular for suction of a mine mine atmosphere behind mining machines or used in drifts with partial or full profile machines, with a casing and several supporting structures covered with filter cloth. mi
    The aim of the invention is to create a variable capacity filter for use in lifting mountain
    developments in the tunneling industry, in particular for the suction of the dusty mining atmosphere.
    FIG. 1 shows a filter consisting of several housings; a sectional view: FIG. 2 - one of the buildings; in fig. 3 filtering cell in the profile projection, partial section: in FIG. 4 shows the filtering cell in horizontal projection: MA fig. 5 - the filter with processing of dust is shown, a general view.
    The dust filter includes a housing 1. on the bottom 2 of which a scraper is installed
    conveyor 3, which receives the precipitated and separated dust and transports it from the bottom. The filter includes viewing holes 4.5 for inspecting the case on the left or the right, Case 1 contains inlet 6 and outlet 7 gas channels with a decreasing or increasing cross section of the gas flow. Connecting heads 8.9 are provided for connecting the individual channels, which allow the individual sections 10 to be connected. The channels 6 and 7 can be connected transversely to the direction of air flow, so that their volume corresponds to the conditions or the amount of mine air (Fig. 1).
    The hatched surfaces (Fig. 1) are steel bottom 11 in discharge channel 7. If this is the inlet channel 6, then there is no bottom or is, but with corresponding holes 12, and therefore the dusty raw gas can pass through the holes 12 inwards housing 1. The filter includes filtering cells 13 in the form of frames 14, covered with filter cloth 15. Inside the frame 14, grilles 16 and spacers are installed. The cells are installed on guide rails 18, and shock nozzles 19 are located in the discharge channel 7. The filter has dust ejection 20, ejector 21 and beam injector 22, successively installed one after the other and connected to the scraper conveyor 3. The dust filter is provided with a mixing section 23 and a cyclone 24 connected to the radiation injector 22.
    Dust filter works as follows.
    The contaminated gas flow enters the filter housing 1 and, the passage of the filter cells 13 is cleaned and released into the atmosphere through the discharge channel 7, and the dust collected by the scraper conveyor 3 is directed through dust ejection 20, ejector 21 and radiation injector 22 to the mixing section 23. A dust filter allows you to connect virtually several enclosures to provide virtually any performance. So, you can get filters with a capacity of 200 to 600 m per minute or more. To do this, it is only necessary to interconnect the complete housing assembly in the region of the channels of the unpurified and purified gases or the corresponding heads 8 and 9. This automatically turns out that the dusty mine air, i.e. unpurified gases, exiting on one side, passes through the filter cells and again exits on the other side in the form of purified gas. Due to the special form of implementation of the individual filter cells 13.
    which can be inserted into the housing 1 and removed from it again, as well as the filter cells covered with the material, to the grids with spacers 17: the new filter cloths are ready for operation and effective even if the material that is prone to sticking is filtered and getting stuck. Even under reduced pressure, neither the cage nor the fabrics stretched on it can come into contact with each other, which ensures constant availability.
    Underground, during assembly, the correct or optimum volume is established. The cross-section of the clean gas channel in the direction of air flow from the casing to the casing increases, and the cross-section of the raw gas channel decreases accordingly.
    In order to easily free individual chambers or their filtering cells from adhering dust, the front edge of the frames 14
    The 5 filtering cells 13 and. The viewing openings, as the front wall of the channel, are equipped with pressurized impact nozzles 19 connected to a compressed air supply system. Due to the attachment of these pressure hammer nozzles to the air supply system, the filter cloths on the grids or the filter cell material are inflated, so that even wet dust separates and falls to the bottom of the housing.
    5 where it enters the scraper conveyor 3 and is retracted further.
    The scraper conveyor at the bottom of the casing has a dust outlet at the end, which is connected to an air-jet injector with a pneumatic sprinkler using a jet nozzle. Dry, but still suspended dust, when processed in series-connected aggregates, is moistened with water and stirred, after which it can be
    5 to be transported from the bottom together with the rest of the transported material or separately. To optimize the mixing effect, especially in the presence of fine-grained and water-repellent
    0 material jet injector is connected to the mixing screw with exhaust cyclones. Thereby, the material is discharged and transferred to a belt conveyor, through which it can be transported from the bottom together with another transported material or separately.
