Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0023] Reference Figure 1-Figure 5 The wastewater treatment filter press comprises a head plate 1 and a tail plate 2, a cross beam 3 is symmetrically fixedly installed between the head plate 1 and the tail plate 2, a plurality of filter plates 4 are horizontally slidably installed between the head plate 1 and the tail plate 2, the filter plate 4 is composed of a filter frame 41, a permeate filter element 42 and a discharge pipe 43, the filter frame 41 is horizontally slidably configured between two cross beams 3, the permeate filter element 42 is fixedly embedded in the filter frame 41, and a diversion port is opened through the center of the surface, a water inlet corresponding to the position of the diversion port is opened on the surface of the tail plate 2, the discharge pipe 43 is fixedly installed on the surface of the filter frame 41, and is connected with the permeate filter element 42, a hydraulic cylinder 5 is fixedly installed on the surface of the head plate 1, a driving shaft of the hydraulic cylinder 5 passes through the head plate 1, and a pressure plate 6 is fixedly installed.

[0024] A slide bar 7 is vertically fixedly installed on the upper surface of the filter plate 4, and a U-shaped scraper 8 is slidably sleeved on the slide bar 7. A slide plate 9 is symmetrically fixedly installed on the surface of one of the filter plates 4 close to the tail plate 2, and through openings 10 are symmetrically opened on the surfaces of the remaining filter plates 4. Two slide plates 9 are respectively slidably configured in the multiple through openings 10, and a mounting plate is fixedly installed on the surface of the tail plate 2. A threaded rod 11 is vertically rotatably installed on the upper surface of the mounting plate, and a slide block 12 is threadedly sleeved on the threaded rod 11. The slide block 12 is fixedly connected to the tail plate 2 close to itself through a telescopic rod 13.

[0025] Before performing filter pressing, it is necessary to start the hydraulic cylinder 5 and control the pressure plate 6 to push the multiple filter plates 4 to move and stick tightly together until the multiple filter plates 4 are tightly pressed between the pressure plate 6 and the tail plate 2. Then the filter pressing work can be performed. During the movement of the multiple filter plates 4, the multiple scrapers 8 will move with the multiple filter plates 4 respectively, and with the cooperation between the through-hole 10 and the slide plate 9, the multiple scrapers 8 can move vertically together.

[0026] After the filtration work is completed, the hydraulic cylinder 5 is started again to control the pressure plate 6 to move toward the direction close to the head plate 1, and then the multiple filter plates 4 are pulled apart, and the threaded rod 11 is rotated to control the slider 12 threadedly sleeved on the threaded rod 11 to move the multiple scrapers 8 vertically downward. When the multiple scrapers 8 move downward, they will slide in contact with the surfaces of the multiple filter plates 4 respectively, so that the materials attached to the surfaces of the filter plates 4 can be scraped off, making the discharge of the materials more thorough and improving the discharge efficiency.

[0027] L-shaped support blocks 14 are fixedly installed on the front and rear surfaces of the filter frame 41, and rotating shafts are rotatably installed on the front and rear surfaces of the pressure plate 6.

[0028] The roller 15 and the support block 14 can respectively support the pressure plate 6 and the filter plate 4, while the ball 17 can reduce the friction between the contact surface of the support block 14 and the slide groove 16 to avoid the filter plate 4 from getting stuck when moving horizontally.

[0029] A transmission assembly is provided on the upper surface of the mounting plate, and the transmission assembly is used to control the rotation of the threaded rod 11. The transmission assembly includes a rotating rod 18 vertically mounted on the upper surface of the mounting plate, two sprockets 19 and a chain 20. The two sprockets 19 are fixedly sleeved on the rotating rod 18 and the threaded rod 11 respectively, and the chain 20 is meshed and wound around the two sprockets 19.

[0030] By rotating the rotating rod 18, the threaded rod 11 will rotate together under the transmission effect of the two sprocket wheels 19 and the chain 20. There is no need to stand at a high place to control the rotation of the threaded rod 11, which is more convenient.

[0031] When the filter press is completed, the hydraulic cylinder 5 is started again to control the pressure plate 6 to move toward the direction close to the head plate 1, and then the plurality of filter plates 4 are pulled apart, and the threaded rod 11 is rotated to control the slider 12 threadedly sleeved on the threaded rod 11 to move the plurality of scrapers 8 vertically downward. When the plurality of scrapers 8 move downward, they will slide in contact with the surfaces of the plurality of filter plates 4, so that the materials attached to the surfaces of the filter plates 4 can be scraped off, so that the discharge of the materials is more thorough and the discharge efficiency can be improved.
