Description

Technical Field

[0001] This utility model relates to the field of diaphragm filter press technology, specifically a filtration structure combining a polypropylene filter plate and a filter cloth. Background Technology

[0002] Diaphragm filter presses have been widely used in various fields requiring solid-liquid separation. They are considered an upgraded replacement for ordinary chamber filter presses. Diaphragm filter presses demonstrate superior performance in terms of processing capacity per unit area, reduction of filter cake moisture, and adaptability to the properties of the materials being processed.

[0003] The compression protrusions on the flexible membrane plate of the existing filter plate are not misaligned. This means that when two adjacent filter plates come into contact, the flexible plate cannot fully compress the sludge between the filter cloths during compression, affecting the compression filtration effect. At the same time, the existing filter plate filtration structure lacks a reinforcing structure on the filter cloth, resulting in poor tensile strength when the filter cloth is compressed. The filter cloth is easily torn and damaged by the compression force, thus compromising the filtration effect of the filter cloth. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a filtration structure that combines a polypropylene filter plate and a filter cloth. By setting the positions of the large extrusion protrusions in a staggered manner on the adjacent flexible plates, the large extrusion protrusions can fully squeeze the sludge between the filter cloths when the adjacent flexible plates are squeezing the sludge, thereby squeezing out the water in the sludge and ensuring the squeezing and filtration effect. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filtration structure combining a polypropylene filter plate and a filter cloth, comprising a filter plate and filter cloth sleeved on both sides of the filter plate, an octagonal flexible plate being provided in the central area of ​​the filter plate, small extrusion protrusions integrally formed on the side of the flexible plate, large extrusion protrusions being provided between the small extrusion protrusions, a reinforcing ring being provided in the center of the filter cloth, a reinforcing cloth strip being provided on the outer ring side of the reinforcing ring, and a partition plate being sandwiched in the center of the filter plate.

[0006] Furthermore, the filter plate has water passage holes at its four corners, and Y-shaped water delivery holes are connected between the water passage holes and the grooves of the filter plate. The filter cloth has Velcro fasteners on its four edges.

[0007] Furthermore, the large extrusion protrusions on the flexible plates on both sides of the filter plate are staggered, and a support frame is fixedly installed on the upper part of the symmetrical outer side of the filter plate.

[0008] Furthermore, anti-slip wheels are installed on the lower side of the support frame, and a feed hole is opened in the center of the filter plate.

[0009] Furthermore, a cavity is provided between the partition plate and the flexible plate, and the filter cloth has a circular hole corresponding to the position of the water passage hole on the filter plate.

[0010] Furthermore, the loop and hook sides of the three Velcro straps on the same edge of the filter cloth are staggered, and the centers of the two filter cloths are connected by a circular pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model sets the positions of the large extrusion protrusions on the adjacent flexible plates in a staggered manner, so that when the adjacent flexible plates are extruding sludge, the staggered large extrusion protrusions can fully squeeze the sludge between the filter cloths, thereby squeezing out the water in the sludge and ensuring the extrusion filtration effect. 2. This utility model strengthens the filter cloth in four directions and at the center hole by setting reinforcing rings and reinforcing cloth belts, ensuring the tensile strength of the filter cloth and preventing it from being torn and damaged under the action of extrusion pressure, thereby ensuring the filtration effect of the filter cloth.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5This embodiment provides a technical solution: a filtration structure combining a polypropylene filter plate and a filter cloth, including a filter plate 1 and filter cloth 8 sleeved on both sides of the filter plate 1. An octagonal flexible plate 4 is provided in the central area of ​​the filter plate 1. Small extrusion protrusions 7 are integrally formed on the side of the flexible plate 4. Large extrusion protrusions 6 are provided between the small extrusion protrusions 7. A reinforcing ring 10 is provided in the center of the filter cloth 8. A reinforcing cloth strip 11 is provided on the outer ring side of the reinforcing ring 10. A partition plate 13 is sandwiched in the center of the filter plate 1.

[0016] like Figure 1-5 As shown, two filter cloths 8 are placed on both sides of the filter plate 1 after passing through the feed hole 12, and are fixed to the filter plate 1 by Velcro 9. After the two adjacent filter plates 1 are squeezed together, sludge is filled into the cavity between the filter cloths 8. Pressurized water enters the cavity between the partition plate 13 and the flexible plate 4 through the water inlet hole on the lower side of the filter plate 1, causing the flexible plate 4 to expand, thereby squeezing the sludge between the filter cloths 8. The water in the sludge enters the water passage hole 5 through the water conveying fine hole 14 and flows out. By setting the position of the large squeezing protrusion 6 on the adjacent flexible plates 4 in a staggered manner, the large squeezing protrusion 6 can fully squeeze the sludge between the filter cloths 8 when the adjacent flexible plates 4 squeeze the sludge, thereby squeezing the water in the sludge clean and ensuring the squeezing filtration effect. By using reinforcing rings 10 and reinforcing cloth belts 11, the filter cloth 8 is reinforced in four directions and at the center hole, ensuring the tensile strength of the filter cloth 8 and preventing it from being torn and damaged under compressive force, thereby ensuring the filtration effect of the filter cloth 8.

[0017] The filter plate 1 has water passage holes 5 at its four corners. The water passage holes 5 are connected to the grooves of the filter plate 1 by Y-shaped water delivery holes 14. The filter cloth 8 has Velcro 9 on its four edges.

[0018] The large extrusion protrusions 6 on the flexible plates 4 on both sides of the filter plate 1 are staggered. A support frame 2 is fixedly installed on the upper part of the symmetrical outer side of the filter plate 1. The support frame 2 can be set on the crossbeam structure by means of anti-slip wheels 3. The flexible plate 4 is made of rubber material and the filter plate 1 is made of polypropylene material.

[0019] Anti-slip wheels 3 are installed on the lower side of the support frame 2, and a feed hole 12 is opened in the center of the filter plate 1.

[0020] A cavity is provided between the partition plate 13 and the flexible plate 4, and the filter cloth 8 has a round hole at the position of the water passage hole 5 on the filter plate 1.

[0021] The three Velcro straps 9 on the same edge of the filter cloth 8 have their napped and hooked sides staggered, and the centers of the two filter cloths 8 are connected by a circular pipe.

[0022] The working principle of the filtration structure combining a polypropylene filter plate and filter cloth provided by this utility model is as follows: Figures 1-5As shown, two filter cloths 8 are placed on both sides of the filter plate 1 after passing through the feed hole 12, and are fixed to the filter plate 1 by Velcro 9. After the two adjacent filter plates 1 are squeezed together, sludge is filled into the cavity between the filter cloths 8. Pressurized water enters the cavity between the partition plate 13 and the flexible plate 4 through the water inlet hole on the lower side of the filter plate 1, causing the flexible plate 4 to expand, thereby squeezing the sludge between the filter cloths 8. The water in the sludge enters the water passage hole 5 through the water conveying fine hole 14 and flows out. By setting the position of the large squeezing protrusion 6 on the adjacent flexible plates 4 in a staggered manner, the large squeezing protrusion 6 can fully squeeze the sludge between the filter cloths 8 when the adjacent flexible plates 4 squeeze the sludge, thereby squeezing the water in the sludge clean and ensuring the squeezing filtration effect. By using reinforcing rings 10 and reinforcing cloth belts 11, the filter cloth 8 is reinforced in four directions and at the center hole, ensuring the tensile strength of the filter cloth 8 and preventing it from being torn and damaged under compressive force, thereby ensuring the filtration effect of the filter cloth 8.
