    1. A filtering apparatus having a filtering device operating under gage pressure and vacuum, comprising a layer of filtering material e.g. a filter cloth for extracting solid particles from liquids, characterized in that the filtering device is a vacuum-filtering device (10, 20, 40), and in that the whole vacuum-filtering device (10, 20, 40) including the bearings, the driving system, the controls and the like is placed in a gage pressure space (11) to which the operators have access, which is under gage pressure and which is shut off from the outside atmosphere.

    (54) DEVICE FOR SEPARATION OF SOLID SUBSTANCES
    FROM LIQUID
    one
    The invention relates to filter devices, in particular, devices for separating solids from liquids.
    A device for separating solids from a liquid is known, comprising a vacuum filter and devices for feeding the suspension and removing the filtrate. and solids With the shortage of such a device is B. THOM, that the residual moisture of solids depends on the difference between atmospheric pressure and. corresponding vapor pressure of the liquid from which solids should be separated. Thus, it is impossible to achieve very low residual moisture values. Although it is possible to achieve a reduction in residual moisture by extending the time & ssagania with a maximum pressure difference, this reduction / is so small that, due to the energy costs required for this purpose, the flowing air must be constantly sucked off using a vacuum pump) unprofitable. In addition, it is unprofitable that as the S extends the suction time, the productivity decreases.
    Closest to the proposed technical essence and the achieved result is a device containing a vacuum filter with suspension supply pipes & removal of filtrate and solids and pressure chamber 2.
    A disadvantage of the prior art is the complexity of the design.
    The purpose of the invention is to simplify the design while maintaining a low balance & accurate moisture content of solids.

    The goal is achieved by the fact that in a device containing a vacuum filter with nozzles. Supplying a suspension of fl urate and solids to the inlet chamber, a vacuum filter is ostano otten in a pressure chamber equipped with a uuno 30Mj located at its outlet. FIG. 1 is a schematic representation of di. vacuum filter, placed in the flow chamber of the pressure & gigonic pressure, general view | in fig. 2 is a vacuum belt filter placed in an underground tunnel, about & my view; on. 3 is a variant of the device used in paper production. The device contains a chamber pressure pressure 1, through which service personnel can pass. In this chamber is a vacuum filter 2 (disk or tape, or filter of any design). Gateway 3 serves to expel a filter taken out of the filter from the pressure chamber (pressure chamber 1). Through the gateway 4, service personnel can enter the overpressure chamber 1. To establish the overpressure of the desired size, chamber 1 uses an air commision spring 5. With the help of a compressor, compressed air is blown into chamber 1 until the pressure / pressure desired in each particular case is reached. In addition, the compressor 5 serves to compensate for the pressure losses that occur when solids are released through the gate 3 and as they pass through the gate 4. When using this device in the underground gallery, the vacuum belt filter 2 is located between the layers 6 of the rock. By means of a wall laid between the layers 6, a sealed chamber 1 is created in which an overpressure of the desired size can be easily installed. In wall 6, it is preferable to double up the mouth 4. Through the stencil 6, not only compressed air is fed into chamber 1, Ne and suspension. The pipeline 7 is then used to supply the suspension. The sediment 6 formed on the webbing filter is fed to the gransporger belt 9, which is movable in horizontal and vertical planes. On the conveyor belt 9 solids are sent to the warehouse 10. Under the belt filter there is a collector 11 connected to a coarse pipe, KOTOpoNdy supplies air and water from the filtrate, "The device allows processing of relatively large raw material at the place of extraction - without the need for their prior submission to the earth's surface. The device of FIG. 3, contains a bladder pressure chamber 1 in which the vacuum filter is located
    [2]
    2. Tubes 12 for removal of the filtrate are connected to two outlet piping pipes through control of head 13. Through valve 14 to regulate the amount of air exhaust pipe is connected to cyclone 15, rotated outside, chamber 1 and equipped with pipe 16 for air discharge . The other outflow pipeline, in which the valve 17 is placed to control the amount of filtrate, is connected to a collector 18 located outside the non-shelving chamber 1. Solids are discharged from the housing 1 through the outlet pipe 19. The vacuum filter is placed in the bath 2O. With large filtering devices, the overpressure chamber is a passage room. With this form of implementation, it is advisable to provide that the chamber of pressure should have a gateway with a pressure-equalizing device used for service personnel during the operation of the vacuum filter. If one considers that a pressure of 1.5 bar corresponds to a depth of about 5 m, it is obvious that with a short stay of the staff in the overpressure chamber there are no problems regarding the health of the staff. Thus, by installing a vacuum filter in a pressure chamber equipped with a gate located at its outlet, the design of the device is simplified while the residual moisture of the solids is low. A formula for separating solids from a liquid, containing a vacuum filter with suspension and reject supply nozzles, filter solids and a pressure chamber, characterized in that it is easy to keep sufficient moisture content of solids, akzotm filter is installed in the pressure
