Description

Technical Field

[0001] The invention relates to the technical field of diaphragm filter presses, in particular to a diaphragm filter press. Background Art

[0002] The filter press uses a special filter medium to exert a certain pressure on the object, causing the liquid to seep out. It is a commonly used solid-liquid separation equipment and is widely used in environmental protection industries such as medicine, chemical industry, standard parts, pharmaceuticals, metallurgy, non-standard screws, dyes, food, brewing, ceramics, oil refining, and sewage treatment. Among them, the diaphragm filter press is a type of filter press, which is a filter press with a layer of elastic membrane between the filter plate and the filter cloth. When the feeding is completed during use, the high-pressure fluid or gas medium can be injected into the diaphragm plate. At this time, the entire diaphragm will bulge to compress the filter cake, thereby achieving further dehydration of the filter cake, which is commonly referred to as squeeze filtration.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] See attached Figure 1 -Attached Figure 7A membrane filter press comprises a filter press body 1 and a plurality of filter plates 4, wherein the filter press body 1 comprises a push plate 2 and a thrust plate 3, a conducting pipe 5 is fixedly installed through the center of the filter plate 4, a drain port and an air inlet are arranged on the filter plate 4, the filtered sewage is discharged through the drain port, and air is injected into the diaphragm 6 through the air inlet to expand the diaphragm 6, compress the sludge, and squeeze out the remaining water; diaphragms 6 are fixedly installed on the outer surfaces of the opposite sides of the filter plate 4, and the outer surfaces of the opposite ends of the filter plate 4 are respectively fixedly installed with a first fixed plate 7 and a second fixed plate 8, and the outer surfaces of the first fixed plate 7 and the second fixed plate 8 at both ends are rotatably installed between them There are rollers 9, and the outer surfaces of the two rollers 9 are sleeved with feeding belts 10. The outer surface of the feeding belt 10 is penetrated with an installation port, and the inner wall of the installation port is fixedly installed with a filter cloth 11. The center position of the filter cloth 11 is fixedly installed with a pressure ring 12 matching the guide tube 5, and the outer surface of the pressure ring 12 is evenly fixedly installed with a plurality of top beads 30 in the circumferential direction. The outer surface near the top of the first fixed plate 7 is installed with a driving mechanism that drives a roller 9 at a corresponding position to rotate. The filter press body 1 is also equipped with a plate separator 29 for pulling and moving multiple filter plates 4 in sequence, and an electromagnet is fixedly installed at the bottom of the plate separator 29. The control method of the electromagnet is through the It is controlled by a matching external controller, and the control circuit can be realized by simple programming by technicians in this field. It belongs to the common knowledge in this field and is only used without improvement. When multiple filter plates 4 are pulled and moved in sequence, when the electromagnet moves to the support beam (the support beam is made of ferromagnetic material) on the side of the corresponding filter plate 4, the external controller turns on the power of the electromagnet, so that the electromagnet is energized to generate magnetism, and the support beam on the side of the corresponding filter plate 4 is sucked, so that the plate separator 29 pulls and moves the corresponding filter plate 4; after the filter plate 4 is pulled and moved to a certain position, the external controller disconnects the power of the electromagnet, so that the electromagnet is powered on and the magnet is sucked. The magnet no longer attracts the support beam on the side of the filter plate 4, so that the plate separator 29 will not drive the filter plate 4 to move when it moves again; the plate separator 29 reciprocates in this way to realize the sequential pulling and moving operation of multiple filter plates 4; and the horizontal height of the electromagnet on the plate separator 29 is slightly higher than the top of the support beam on the side of the filter plate 4, so as to ensure that the electromagnet can generate sufficient attraction to the support beam, so that the plate separator 29 can stably drive the corresponding filter plate 4 to move; a receiving hopper 28 is fixedly installed at the bottom of the filter press body 1, and the receiving hopper 28 is arranged directly below the multiple filter plates 4, and the receiving hopper 28 is used to receive the filter cake dropped from the filter cloth 11.

[0029] When in use, the push plate 2 is used to push the plurality of filter plates 4 together and merge them, so that the adjacent pressure rings 12 are pressed against each other through the top beads 30, and the pressure rings 12 are pressed against the pipe mouth of the conducting pipe 5, and then sewage is injected into the space between the two adjacent filter plates 4 through the conducting pipe 5 from the water inlet end of the filter press body 1, so that the sewage enters between the adjacent filter cloths 11, so that the filter cloths 11 can filter the sewage, and the filtered sewage is discharged through the drainage holes provided on the filter plate 4 for collection. After filtering for a certain period of time, gas is injected into the filter plate 4 to expand the diaphragm 6, squeeze the sludge between the filter cloths 11, squeeze out the remaining water, and squeeze the sludge to form a filter cake.

[0030] In this embodiment, the driving mechanism includes a spline shaft 13 fixedly installed at the rotation center of the roller 9, the spline shaft 13 passes through the outer surface of the first fixed plate 7 and is rotatably installed therewith, two tension spring rods 19 are fixedly installed on the outer surface of the first fixed plate 7, and a mounting box 14 is fixedly installed at the telescopic ends of the two tension spring rods 19, a worm gear 15 is installed inside the mounting box 14, and the worm gear 15 is slidably installed on the spline shaft 13 through a spline, and a worm 16 is rotatably installed between the outer surfaces of the upper and lower ends of the mounting box 14, and the worm 16 is meshed with the worm gear 15. The self-locking characteristics of the worm wheel 15 and the worm 16 can ensure that the feed belt 10 will not move during the filter pressing operation, thereby ensuring the certainty of the position of the filter cloth 11; a transmission assembly is installed between the top of the filter press body 1 and the worm 16, and the transmission assembly includes a transmission rack 20 fixedly installed on the top of the filter press body 1, a one-way bearing 17 is installed on the top of the worm 16, and a transmission gear 18 is installed on the top of the worm 16 through the one-way bearing 17. The transmission gear 18 is intermittently meshed with the transmission rack 20, and two push-off mechanisms are equidistantly installed on the feed belt 10.

[0031] When the filter plate 4 is pulled, the transmission gear 18 rotates counterclockwise on the transmission rack 20, so that the transmission gear 18 drives the worm 16 to rotate in the same direction through the one-way bearing 17, and the worm 16 drives the worm wheel 15 meshing therewith to rotate clockwise, so that the worm wheel 15 can drive the roller 9 to rotate in the same direction through the spline shaft 13, and the roller 9 can drive the feeding belt 10 and the filter cloth 11 to rotate synchronously clockwise, thereby completing the cleaning operation of the filter cake on the filter cloth 11.

[0032] After the filtration is completed, the push plate 2 is reset, and each filter plate 4 is pulled apart in turn by the plate separator 29. When the filter plate 4 is pulled, the transmission gear 18 installed on the filter plate 4 through the first fixed plate 7 will roll on the transmission rack 20, so that the transmission gear 18 drives the worm 16 to rotate through the one-way bearing 17, so that the worm 16 drives the worm wheel 15 meshing with it to rotate, and the worm wheel 15 drives the spline shaft 13 to rotate through the spline, so that the spline shaft 13 can drive the roller 9 to rotate, so that the feeding belt 10 sleeved on the outer surface of the roller 9 can drive the filter cloth 11 to move, so that the filter cloth 11 bends and deforms when it moves to the roller 9, so that the filter cake adhered to the surface of the filter cloth 11 can automatically fall off, and there is no need to manually remove the filter cake later, which can effectively improve the cleaning efficiency of the filter cake.

[0033] In this embodiment, the pushing mechanism includes a mounting block 22 fixedly mounted on the outer surface of the feeding belt 10, and a torsion shaft 23 is mounted on the outer surface of the mounting block 22. A unidirectionally rotatable V-shaped block 24 is mounted on the mounting block 22 through the torsion shaft 23. A limit block 25 for unidirectional rotation of the limited V-shaped block 24 is fixedly mounted on the upper surface of the mounting block 22. An unlocking component for pushing the V-shaped block 24 is mounted on the outer surface near the top of the first fixed plate 7. The unlocking component includes a mounting groove 26 opened on the outer surface of the first fixed plate 7, and an L-shaped push rod 27 corresponding to the V-shaped block 24 is rotatably mounted on the inner wall of the mounting groove 26 through a torsion spring. An L-shaped push rod 27 is also separately fixedly mounted on the outer surface of the top of the thrust plate 3 near the filter plate 4. By separately fixing the L-shaped push rod 27 on the top of the thrust plate 3, the V-shaped block 24 correspondingly mounted on a filter plate 4 close to the thrust plate 3 can be pushed and unlocked, thereby ensuring the normal use of the filter plate 4 on the most side.

[0034] When in use, the L-shaped push rod 27 installed in the installation groove 26 can be rotated by the torsion spring to facilitate the V-shaped block 24 to pass over the L-shaped push rod 27, so that the L-shaped push rod 27 can be retracted into the installation groove 26 to avoid the L-shaped push rod 27 and the V-shaped block 24 from getting stuck.

[0035] In this embodiment, a cleaning mechanism is installed at the top and bottom of the second fixed plate 8, and the cleaning mechanism includes a cross bar 21 fixedly installed at both ends of the second fixed plate 8. A plurality of bristles are evenly fixedly installed on the outer surface of the cross bar 21 close to the feeding belt 10, and the bristles are in contact with the surface of the feeding belt 10.

[0036] When in use, the brush bristles installed on the second fixing plate 8 through the cross bar 21 can clean the surface of the filter cloth 11 passing through, so as to clean the filter residue firmly adhered to the surface of the filter cloth 11, so that the surface of the filter cloth 11 can be cleaned more completely.

[0037] In this embodiment, the pressure ring 12 and the top bead 30 are both made of rubber material, so that the pressure ring 12 can pass over the roller 9 along with the filter cloth 11 .

[0038] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, the push plate 2 pushes the plurality of filter plates 4 to be close to each other and merged, so that the adjacent pressure rings 12 are pressed against each other through the top beads 30, and the pressure rings 12 are pressed against the pipe mouth of the guide tube 5, and then the sewage is injected into the space between the two adjacent filter plates 4 through the guide tube 5 from the water inlet end of the filter press body 1, so that the sewage enters between the adjacent filter cloths 11, so that the filter cloths 11 can filter the sewage, and the filtered sewage is discharged through the drainage holes provided on the filter plate 4 for collection. After filtering for a certain period of time, gas is injected into the filter plate 4 to expand the diaphragm 6, squeeze the sludge between the filter cloths 11, squeeze out the remaining water, and squeeze the sludge to form a filter cake;

[0039] After the filtration is completed, the push plate 2 is reset, and each filter plate 4 is pulled apart in turn by the plate separator 29. When the filter plate 4 is pulled, the transmission gear 18 installed on the filter plate 4 through the first fixed plate 7 will roll on the transmission rack 20, so that the transmission gear 18 drives the worm 16 to rotate through the one-way bearing 17, so that the worm 16 drives the worm wheel 15 meshing with it to rotate, and the worm wheel 15 drives the spline shaft 13 to rotate through the spline, so that the spline shaft 13 can drive the roller 9 to rotate, so that the feeding belt 10 sleeved on the outer surface of the roller 9 can drive the filter cloth 11 to move, so that the filter cloth 11 bends and deforms when it moves to the roller 9, so that the filter cake adhered to the surface of the filter cloth 11 can automatically fall off, and there is no need to manually remove the filter cake later, which can effectively improve the cleaning efficiency of the filter cake;

[0040] At the same time, the brush bristles installed on the second fixed plate 8 through the cross bar 21 can clean the surface of the filter cloth 11 passing through, so as to clean the solid filter residue adhering to the surface of the filter cloth 11, so that the surface of the filter cloth 11 can be cleaned more completely;

[0041] When the push plate 2 pushes the filter plate 4 to move, the transmission gear 18 rotates in the opposite direction on the transmission rack 20. At this time, the one-way bearing 17 will not drive the worm 16 to rotate, so as to avoid the misalignment of the adjusted filter cloth 11 and affect the subsequent filter pressing operation.

[0042] When the feeding belt 10 moves, the mounting block 22 drives the V-block 24 to move synchronously. When the V-block 24 moves to the shaft of the worm 16, due to the unidirectional limiting effect of the limiting block 25 on the V-block 24, the V-block 24 can apply an outward thrust to the shaft of the worm 16, and the side of the V-block 24 blocks and limits the shaft, so that the transmission gear 18 and the mounting box 14 can be separated from the transmission rack 20 as a whole, so that the transmission gear 18 is no longer meshed with the transmission rack 20, so that when the filter plate 4 is continuously pulled, the feeding belt 10 will no longer drive the filter cloth 11 to move, which means that the filter cloth 11 is adjusted in place;

[0043] After the two adjacent filter plates 4 are brought together and merged, the L-shaped push rod 27 installed on the adjacent filter plates 4 will push the V-shaped block 24 away from the limit block 25, so that the side of the V-shaped block 24 no longer blocks the shaft of the worm 16, so that the installation box 14 drives the transmission gear 18 as a whole to be pulled toward the transmission rack 20 under the tension of the tension spring rod 19, so that the transmission gear 18 can mesh with the transmission rack 20 again for subsequent transmission operations.

[0044] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
