DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 6 , this embodiment provides the following technical solutions:

[0027] like Figure 1-Figure 5 As shown, a sludge treatment filter press comprises: a frame 1, a baffle plate 101 and a mounting plate 104 are fixedly mounted on the upper surface of the frame 1, a hydraulic push rod 3 is fixedly mounted on one end of the mounting plate 104, the front end of the hydraulic push rod 3 passes through the mounting plate 104 and a top pressure plate 301 is fixedly mounted on the end of the piston rod, a plurality of groups of diaphragm filter plates 4 for filtering sludge are slidably mounted in the frame 1, connecting rings 401 are fixedly mounted on both sides of the diaphragm filter plates 4, a spacing limiting mechanism 5 is detachably connected between the diaphragm filter plates 4 and the top pressure plate 301 through the connecting ring 401, and the other end of the diaphragm filter plate 4 is connected to one end of the baffle plate 101 through the spacing limiting mechanism 5, and the hydraulic push rod 3 is flush with the diaphragm filter plate 4.

[0028] A funnel 2 is fixedly installed in the frame 1. The funnel 2 is located at the upper end of the membrane filter plate 4. The leakage opening of the funnel 2 is in a long strip shape.

[0029] One end of the baffle plate 101 is connected with two groups of water pipes 102 and one group of mud inlet pipes 103 . The water pipes 102 and the mud inlet pipes 103 can be connected with the membrane filter plate 4 through the baffle plate 101 .

[0030] Connecting blocks 105 are fixedly installed at both ends of the frame 1, and a guide column 6 is slidably installed in the connecting block 105. A butterfly bolt 601 is threadedly installed at one end of the connecting block 105, and the butterfly bolt 601 can be threadedly pressed on the outer surface of the guide column 6.

[0031] The guide column 6 can pass through the membrane filter plate 4 and make the membrane filter plate 4 slide on the outer surface of the guide column 6 .

[0032] Through the design of the mud inlet pipe 103, the baffle plate 101, the hydraulic push rod 3, the top pressure plate 301, the diaphragm filter plate 4 and the water pipe 102, when the sludge is filtered, the hydraulic push rod 3 pushes the top pressure plate 301 to squeeze the multiple groups of diaphragm filter plates 4 together, and then the mud pump can be connected to the mud inlet pipe 103, and the sludge is supplied to the multiple groups of diaphragm filter plates 4, so that the sludge in the filter chamber is compressed under high pressure, and the water therein flows out from the hydrophobic holes of the diaphragm filter plate 4 and is discharged from one group of water pipes 102, while the other group of water pipes 102 supplies clean water to the diaphragm plate to further squeeze the sludge, and the solid particles are tightly combined in the diaphragm filter. A mud cake is formed in the plate 4. At the same time, due to the pressure, a water film is formed between the mud cake and the filter cloth, which makes it easy to separate the mud cake from the membrane filter plate 4. Then, the hydraulic push rod 3 can be started again to pull back the top pressure plate 301. The top pressure plate 301 can pull multiple groups of diaphragm filter plates 4 to unfold through the spacing limit mechanism 5. Since the length of the spacing limit mechanism 5 is consistent, the spacing between each membrane filter plate 4 can be equal, and the mud cake in the membrane filter plate 4 will detach from it and fall into the funnel 2 to achieve the effect of centralized collection and autonomous discharge of the mud cake, thereby eliminating the need for external machinery to unfold the membrane filter plate 4 to clean the mud cake, saving economic consumption.

[0033] like Figure 6 As shown, the spacing limiting mechanism 5 includes two groups of first arc clamps 501 and second arc clamps 502. The first arc clamps 501 and second arc clamps 502 are rotationally connected by a torsion spring. The first arc clamps 501 and second arc clamps 502 can be closed and locked in the connecting ring 401.

[0034] The first arc-shaped clamps 501 are fixedly connected to each other via a steel wire rope 504 , and a pressing plate 503 is fixedly installed on one end of the second arc-shaped clamp 502 in a tilted shape.

[0035] Through the design of the first arc-shaped clamp 501, the second arc-shaped clamp 502, the steel wire rope 504 and the pressing plate 503, when the top pressing plate 301 is pulled back, the locks of the first arc-shaped clamp 501 and the second arc-shaped clamp 502 will pull the multiple groups of membrane filter plates 4 to be unfolded, and because the lengths of the steel wire ropes 504 between the first arc-shaped clamps 501 are equal, the distances between the unfolded membrane filter plates 4 can be equal;

[0036] When the membrane filter plate 4 is to be disassembled and replaced, the staff can press the pressing plate 503 to rotate and expand the second arc clamp 502, so that the arc clamp can be disengaged from the connecting ring 401, and then the butterfly bolt 601 is unscrewed from the connecting block 105, and the guide column 6 is pulled out therefrom, so that the limiting force of the diaphragm filter plate 4 can be contacted, so that the staff can take out the diaphragm filter plate 4 and replace it with a new one. The replacement process does not require the use of any tools, which increases the efficiency of the staff in disassembling the diaphragm filter plate 4.

[0037] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when the sludge is filtered, the hydraulic push rod 3 pushes the top pressure plate 301 to squeeze the multiple groups of diaphragm filter plates 4 together, and then the sludge pump can be used to connect with the sludge inlet pipe 103, and the sludge is supplied to the multiple groups of diaphragm filter plates 4, so that the sludge in the filter chamber is compressed under high pressure, and the water therein flows out from the hydrophobic holes of the diaphragm filter plates 4 and is discharged from one group of water pipes 102, while the other group of water pipes 102 supplies clean water to the diaphragm plate to further squeeze the sludge, and the solid particles are tightly combined with the diaphragm filter plates 4. A mud cake is formed inside. At the same time, due to the pressure, a water film is formed between the mud cake and the filter cloth, which makes it easy to separate the mud cake from the membrane filter plate 4. Then the hydraulic push rod 3 can be started again to pull back the top pressure plate 301. The top pressure plate 301 can pull the multiple groups of membrane filter plates 4 to unfold through the lock of the first arc clamp 501 and the second arc clamp 502. Since the lengths of the steel wire ropes 504 between the first arc clamps 501 are equal, the unfolding spacing of each membrane filter plate 4 can be equal, and the mud cake in the membrane filter plate 4 will detach from it and fall into the funnel 2 to achieve the effect of centralized collection.

[0038] In summary: it has the function of self-cleaning and collecting the mud cake, thereby eliminating the need for external machinery to unfold the membrane filter plate to clean the mud cake, saving economic consumption.
