    1 The invention relates to filtration, in particular to drum or disk filters for cleaning liquid. A vacuum filter is known, having a filter cell that is partially submerged in a trough, in which each cell has a port for draining the filtrate in a vacuum chamber, an axial tube for draining the filtrate from the vacuum chamber and a pressure chamber for compressed air or steam for purging the C13 filter cake. The disadvantages of the known filter are the complexity of its design and operation. The purpose of the invention is to simplify the design and operation of the filter. The goal is achieved by the fact that a vacuum filter, having a filter-folding cell that is partially immersed in a trough, has a branch pipe for draining the filtrate into the vacuum chamber, an axial tube for draining the filtrate from the vacuum chamber, and a pressure chamber for compressed air or steam for purging the filter cake, sleeping the wand with a nozzle mounted on the pressure chamber and forming a jet pump together with the nozzle of the cell. Moreover, the nozzle for removal of the filtrate from the cell into the vacuum chamber is made in the form of a Venturi tube. Figure 1 shows the filter, general view, section; figure 2 - section aa in figure 1; on fig.Z - filter, cross section; figure 4 - pipe for removal of filtrate and nozzles. The filter includes a filter cell element 1, partially immersed in a trough 2. The cell element 1 is covered on top with sheet filter material 3, for example, a perforated sheet, filter cloth and / or filter cloth. The cell element 1 rotates relative to the axial tube 4. The filtrate from the cell element is sucked through the filtrate extractor 5 and the conduit 6. Each tube is provided with a nozzle 7 for draining the filtrate into the vacuum chamber 8. Inside the cell element there are nozzles 9 for compressed air or steam, supplied through pipe 4, and which is fixed so installed. 592 that it faces the nozzle 7 and occupies a position in which the residue remaining after filtration is blown away. The design of the nozzle 7 and the nozzle 9 for compressed air or steam is such that, collectively, they form a jet pump of compressed air or steam, and the sediment is blown off by blowing compressed air or steam through the nozzles 9 for a short period of time. Tests show that the nozzle 7 is made in the form of a Venturi tube and, as one of the options, should have an internal diameter of 45 mm and nozzles 9 should have an internal diameter of 20 mm, the air pressure in the nozzle should be 2.2 bar, and the vacuum in the vacuum chamber 3 mm water column The distance A between the end of the nozzle and the nozzle should be within 0-10 mm, and the holes should be displaced relative to each other by a distance of up to 10 mm, i.e. the position of the nozzle 9 relative to the nozzle 7 is not critical, and the nozzle is able to interact with the nozzle, in a certain range of the angle of rotation of the cell element in the process of its movement in a circle with the cell element. If this angular range is not sufficient, instead of fixing the nozzle stationary, it can be installed with the possibility of moving from the initial position so as to follow the circular path of the nozzle to a predetermined angle and quickly return to its initial position, i.e. to the position of readiness for interaction with the following branch pipe. The wash water is collected in the tray 10 and discharged through line 6. The filter has a device 11 for removing the filtrate cake left after filtering and can be made in the form of a screw conveyor. A device for removing the filtrate cake is installed on one side of the trough 2, filled with the liquid to be filtered, which is partially immersed. cell element. On the other side of the trough, an overflow 12 is made. The cell element can rotate at a constant number of revolutions per minute or make a step motion. 3, each step should correspond to the angular size of the cell. The deflation process can be controlled automatically by means of a valve that is present in the compressed air source or a pair located outside the filter. The control can be carried out mechanically, pneumatically or electrically, depending on the angular position of the cell element. If each cell of a cell element has more than one nozzle, then nozzles 9 can be installed along the wasps of each nozzle. Pipe 7, like nozzles 9, is bent to a horizontal position. The axial tube 4 is divided by a partition 13 into two compartments, compressed air or steam is fed into the left compartment 14, and a vacuum into the right compartment 15. A flush water pan 10 connects 94 to the pipeline 6 passing inside the axial tube 4. The device works as follows . The cell element rotates relatively axially coarse 4. Vacuum is maintained in the cell, the filtrate from the cell is sucked through extractor 5 and discharged through compartment 15 of pipe 4. Filtration cake from the filter surface is blown off by applying compressed air or a pair of nozzles 9 for a short period of time. Before the filtrate cake is blown off, the spraying is carried out with the last packaged water, while spraying is carried out over the immersion levels of the cell in the suspension. Promygochnoy water is washed separately into the tray 10.
