Description

Frame filter presses are widely used in the chemical, food and other industries. . A feature of the proposed filter press, which distinguishes it from the frame presses known in the art, is the ability to flush the entire filtering surface through the nozzles of the pipe mounted in the corner of the frames. This pipe is made rotary around its own axis at an angle from 0 to 90 °. By turning the pipe with a hand lever, you can flush out the water from the nozzles, clog up the filter with dirt, and remove it through a special tray. FIG. 1 is a longitudinal view of the filter; FIG. 2 is a cross section of it, and in FIG. 3 is a side view. Inside the cylindrical housing 7 is mounted a row of frames 2 (Fig. 1). The frames are inserted into the grooves in the walls of the housing 7. The waste chambers serve as interstices between adjacent frames, and the filtered solution is collected inside the frames. of its part, the excretory nipple 9 (Fig. 2), which passes through the vessel wall and is sealed at the outlet with a gasket. A pipe 3 with nozzle nozzles 72 is mounted on the lower corners of the outside frames. Nozzles 72 are directed into the spaces between the frames. The pipe 3 passes through the end walls of the housing in the glands 6 (Fig. 1). The housing is closed by a lid 10, bolted. The pipe 8 (fig. 1) of the connected gland with the pipe 3 (fig. 2) is supplied through separate juice, rinse and water valves to remove the dirt. A frame 4 extends along the body, extending out through the end wall of the body and closed by a lid yoke 5 (Fig. 3). is as follows. placed on the housing 7 and its lid 70 is closed. Further, the lid 10 is opened only when it is necessary to change the canvas bags. Then the cover of the yoke 5 is closed, and the pipe 6yJ Each frame has in the bottom for the removal of waste under all Work on the filter press produced in the canvas mesh frame 2

set in a position in which the nozzles 12 are directed horizontally. This is determined by the arrow on the lever 7 (Fig. 3), which is rigidly seated at the end of the pipe 3 and extending out through the gland.

Next, the juice valve is opened, as a result of which the juice enters through the nozzles 72 into the gap between the frames and is filtered through the canvas on both sides, and then goes through the grooves of the frames through the nipples 9.

After the press is pressed, the juice valve is closed, the rest of the juice is released and the flushing valve is opened.

After washing the entire filtering surface, the lid 5 is opened and the iron box // is removed from tray 4 and water is fed into pipe 3. For the lever 7 slowly turn the pipe 3 from 0 to 90 °. When turning the pipe 3, the water, directed by the nozzles / 2, dilutes the dirt, starting from the bottom and the last, falling down, coming out

Tray 4. Pipe 3 is rotated several times until water starts to flow out of the tray. After that, the access of water is stopped, the pipe 3 is placed in the initial position, the lid of the yoke 5 is closed and the filter press is ready for a new cycle.

Subject invention

A filter press consisting of a horizontally arranged cylindrical body mounted inside its framework, carrying filter surfaces, pipes supplying the mass to be filtered and washing liquid provided with nozzle nozzles and a tray discharging waste, characterized in that the surface of the pipe carrying nozzle nozzles mounted on the corners of the frames and made rotatable around its own axis from 0 ° to 90.
