Description

Technical Field

[0001] The utility model relates to the field of filter plates for filter presses, in particular to an anti-clogging filter plate for filter presses. Background Art

[0002] Filter press is an important solid-liquid separation equipment. The working principle of filter press is mainly to use a hydraulically driven diaphragm pump to inject slurry into the filter chamber formed by adjacent filter plates, and then apply pressure to make water flow out through the filter cloth. Finally, the residual moisture in the filter cake is taken away by high-pressure air, and the connecting rod drives the moving plate to squeeze the filter chamber to discharge the remaining water. As an important solid-liquid separation equipment, filter press plays an indispensable role in many fields. However, in order to improve the solid-liquid separation efficiency and obtain solid materials with lower moisture content, the existing filter press usually applies higher pressure to the processed materials, but at the same time it will derive a problem: the filter cloth and the drainage channel between the filter cloth and the filter plate are easily blocked by solid particles, resulting in abnormal filtration process, the filter cloth service life will be shortened, and the production efficiency will be reduced. For this reason, we propose an anti-clogging filter plate for filter press. Utility Model Content

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides an anti-clogging filter plate for a filter press, which has the following beneficial effects:

[0017] 1. The filter plate of the anti-clogging filter press enters the water permeable port of the filter plate inside the filter plate through the second anti-clogging net, and some large particles of impurities are filtered out by the circular holes on the second anti-clogging net, so as to prevent the larger particles from clogging the holes on the water permeable port of the filter plate, resulting in the sewage being unable to enter the interior of the filter plate through the water permeable port of the filter plate. The second anti-clogging net is used to prevent the sand impurities in the sewage from being squeezed and deformed when the filter plate is squeezed and filtered by the fixing rod and the circular baffle, so as to prevent the filtering effect of the second anti-clogging net from being deteriorated.

[0018] 2. The filter plate of the anti-clogging filter press is entered into the interior of the nozzle body through clean water. When the clean water generates a certain water pressure, it pushes the moving block to move downward inside the nozzle body, so that the nozzle body pushes the connecting water pipe to move downward, so that one end of the connecting water pipe extends from the bottom of the nozzle body, and then the clean water rinses the outer surface of the filter plate through the connecting water pipe and the anti-clogging nozzle, and utilizes the characteristic of water flowing downward due to gravity to clean up impurities on the outer surface of the second anti-clogging net to prevent clogging.

[0028] Furthermore, grooves are respectively provided on both side surfaces of the filter plate 1 , and a filter layer 16 is fixedly installed between two corresponding grooves inside the filter plate 1 , and a first anti-blocking net 6 is fixedly installed between the filter plate 1 and the filter layer 16 .

[0029] Furthermore, the filtering device includes a second anti-blocking net 7, a fixing rod 8 and a circular baffle 9. The second anti-blocking net 7 is fixedly connected to one side of the outer surface of the filter plate 1 corresponding to the filter plate water permeable port 4, and one end of the second anti-blocking net 7 is fixedly connected to the circular baffle 9. A fixing rod 8 is fixedly connected between the circular baffle 9 and the filter plate 1.

[0030] Furthermore, the first anti-blocking net 6 is rectangular, and has a plurality of filter holes, and the aperture of the filter holes of the first anti-blocking net 6 is smaller than the aperture of the filter plate water permeable port 4, and the aperture of the filter holes of the first anti-blocking net 6 is larger than the aperture of the filter layer 16.

[0031] Furthermore, three fixing rods 8 are provided, and the three fixing rods 8 are arranged in a ring around the filter plate water-permeable port 4, and one side of the three fixing rods 8 is fixedly connected to the inner wall of the second anti-blocking net 7, and a circular hole is opened on the outer surface of the second anti-blocking net 7, and the aperture of the circular hole is larger than the aperture of the filter plate water-permeable port 4.

[0032] Furthermore, the cleaning device includes a water pipe interface 10, a nozzle body 11, a moving block 12, a connecting water pipe 13, an anti-blocking nozzle 14 and a spring 15. One side of the filter plate 1 is fixedly connected to the nozzle body 11, the top of the nozzle body 11 is fixedly connected to the through-piece water pipe interface 10, the inside of the water pipe interface 10 is movably connected to the moving block 12, the bottom end of the moving block 12 is fixedly connected to the through-piece connecting water pipe 13, the outer surface of the connecting water pipe 13 is fixedly connected to the anti-blocking nozzle 14, and the inner wall of the nozzle body 11 is connected to the spring 15.

[0034] Working principle: when the filter plate 1 is needed to filter sewage, the filter plate 1 is first installed on the filter press through the filter plate handle 5, and then the sewage enters the groove space on the surface of the filter plate 1 through the filter plate feed port 2. Then, during the process of the sewage entering the internal filter layer 16 of the filter plate 1 through the filter plate water permeable port 4, the sewage must first pass through the second anti-blocking net 7 to enter the filter plate water permeable port 4 inside it, and use the circular holes on the second anti-blocking net 7 to filter out some large particles of impurities to prevent larger particles from clogging the holes on the filter plate water permeable port 4, resulting in the sewage being unable to enter the filter plate 1 through the filter plate water permeable port 4. The fixing rod 8 and the circular baffle 9 are used to prevent the second anti-blocking net 7 from being squeezed and deformed by the silt impurities in the sewage when the filter plate 1 is squeezed and filtered, thereby causing the filtering effect of the second anti-blocking net 7 to deteriorate. Then, when the sewage passes through the filter plate water permeable port When entering the filter plate 1, it needs to pass through the first anti-blocking net 6 to further filter slightly larger impurities in the sewage, so that when the sewage passes through the filter layer 16 for the final filtration, too many impurities cause the filter layer 16 to be blocked. Finally, after the sewage is filtered, the water pipe is fixedly connected to the nozzle body 11 through the water pipe interface 10, and then the clean water enters the inside of the nozzle body 11. When the clean water generates a certain water pressure, it pushes the moving block 12 to move downward inside the nozzle body 11, so that the nozzle body 11 pushes the connecting water pipe 13 to move downward, so that one end of the connecting water pipe 13 extends from the bottom of the nozzle body 11, and then the clean water rinses the outer surface of the filter plate 1 through the connecting water pipe 13 and the anti-blocking nozzle 14, and uses the characteristic of water flowing downward due to gravity to clean up the impurities on the outer surface of the second anti-blocking net 7.
