Description

Technical Field

[0001] This invention relates to the field of filter press technology, specifically to a high-strength rubber diaphragm filter plate and its usage method. Background Technology

[0002] A filter press is a mechanical device that uses a filter medium to apply pressure to the object being filtered, causing the liquid inside to seep out. It is a commonly used solid-liquid separation device. Filter presses were first used in chemical production in the early 18th century and are still widely used in industries such as chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramics, and environmental protection. The core component of a filter press is the filter assembly, which consists of alternating filter plates and filter frames. A space is formed between the filter plate and the filter frame to accommodate the object to be filtered. The filter plate and the filter frame are also provided with through holes for the object to be filtered and for the liquid inside the object to be drawn out. After filtration, a filter cake is formed between the filter plate and the filter frame. For example, the high-pressure double diaphragm filter plate described in patent publication number CN111135616B has a squeezing structure formed by multiple protrusions evenly distributed on the side of the first diaphragm away from the support plate. The squeezing structure is evenly distributed in the central area of ​​the first high-pressure water chamber formed by the participation of the first diaphragm. The squeezing structure can further improve the filtration effect. When the first diaphragm bulges away from the support plate, the squeezing structure also bulges accordingly, thereby further filtration of the object to be filtered. However, in this device, the first diaphragm and the second diaphragm are fixedly connected to the support plate. This setting is not convenient for the separation and cleaning of the first diaphragm and the second diaphragm. It is also not convenient to replace the first diaphragm and the second diaphragm after damage. At the same time, after filtration, the fixed material is easy to adhere to the squeezing mechanism on the surface of the first diaphragm and is not convenient to clean.

[0003] Based on this, a rubber diaphragm filter plate with high support strength and its method of use are provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0004] The purpose of this invention is to provide a rubber diaphragm filter plate with high support strength and its method of use, so as to solve the problems that the first diaphragm and the second diaphragm are inconvenient to disassemble and clean.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-strength rubber diaphragm filter plate includes a first diaphragm, a second diaphragm, and a support plate. The surfaces of the first and second diaphragms are fixedly provided with compression blocks for facilitating filtration. The first and second diaphragms are detachably connected to the support plate. The side of the support plate is fixedly provided with a high-pressure water inlet, a feed inlet, a filter water inlet, and a hot water inlet. The first and second diaphragms are detachably connected to the support plate via an installation mechanism, and are fixed to the surface of the support plate via a fixing mechanism. A cleaning mechanism for cleaning the surface of the first diaphragm is fixedly provided inside the first diaphragm.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] In one embodiment, such as Figures 1-9 As shown, a high-strength rubber diaphragm filter plate includes a first diaphragm 100, a second diaphragm 101, and a support plate 102. Extrusion blocks 107 for facilitating filtration are fixedly provided on the surfaces of the first and second diaphragms 100 and 101. The first and second diaphragms 100 and 101 are detachably connected to the support plate 102. A high-pressure water inlet 105, a feed inlet 103, a filter press inlet 104, and a hot water inlet 106 are fixedly provided on the side of the support plate 102. The first and second diaphragms 100 and 101 are detachably connected to the support plate 102 via an installation mechanism 200. The installation mechanism 200 enables the first diaphragm 100 to be detachably connected to the support plate 102. The first diaphragm 100 and the second diaphragm 101 are detachably mounted on the support plate 102. The first diaphragm 100 and the second diaphragm 101 are fixed to the surface of the support plate 102 by the fixing mechanism 300. The fixing mechanism 300 fixes the first diaphragm 100 and the second diaphragm 101, thereby further fixing the first diaphragm 100 and the second diaphragm 101 to the support plate 102. A cleaning mechanism 500 for cleaning the surface of the first diaphragm 100 is fixedly provided inside the first diaphragm 100. The cleaning mechanism 500 causes the first diaphragm 100 to protrude outward, thereby cleaning the impurities attached to the extrusion block 107 on the surface of the first diaphragm 100.

[0032] In one embodiment, such as Figure 1 and Figure 2 As shown, a first high-pressure water chamber is formed between the first diaphragm 100 and the support plate 102, and a second high-pressure water chamber is formed between the second diaphragm 101 and the support plate 102. The first diaphragm 100 and the second diaphragm 101 are made of water-impermeable deformable materials. The first diaphragm 100 and the second diaphragm 101 can bulge in the direction away from the support plate 102, so that the side of the first diaphragm 100 and the second diaphragm 101 away from the support plate 102 squeezes and filters the object.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, the high-pressure water inlet 105 is connected to the first high-pressure water chamber and the second high-pressure water chamber. The feed inlet 103 and the filter press inlet 104 are both connected to the side of the first diaphragm 100 away from the support plate 102. The feed inlet 103 and the hot water inlet 106 are both connected to the side of the second diaphragm 101 away from the support plate 102. The high-pressure water inlet 105 is used to inject high-pressure water. Water entering through the high-pressure water inlet 105 can push the first diaphragm 100 to bulge away from the support plate 102. The feed inlet 103 is used to feed the filter press. The filter press water generated when the filter press is squeezed is discharged through the filter press inlet 104. The feed inlet 103 and the filter press inlet 104 are both connected to the side of the first diaphragm 100 away from the support plate 102. The hot water inlet 106 is used to introduce hot water or high-temperature steam to heat the filter press.

[0034] In one embodiment, such as Figures 2-4 As shown, the installation mechanism 200 includes an installation block 201, which is fixedly disposed on the back of the first diaphragm 100 and the second diaphragm 101. A connecting plate 202 is fixedly disposed on the surface of the installation block 201, and a connector 203 is fixedly disposed at the top of the connecting plate 202. The connector 203 is used in conjunction with a connector interface 204, which is located at the edge of the surface of the support plate 102. A baffle 2 is fixedly disposed on the edge of the connector interface 204 to prevent the connector 203 from falling off. 06. One end of the insertion interface 204 is connected to the disassembly port 205. During installation, the plug 203 is inserted into the insertion interface 204, and the plug 203 is fixed in the insertion interface 204 by the baffle 206. The first diaphragm 100 and the second diaphragm 101 are installed on the support plate 102. During disassembly, the first diaphragm 100 is moved to the right, so that the plug 203 moves toward the disassembly port 205, thereby allowing the plug 203 to be removed from the disassembly port 205, and the first diaphragm 100 is removed from the support plate 102.

[0035] In one embodiment, such as Figure 3and Figure 5 As shown, the fixing mechanism 300 includes a fixing block 301, which is fixed to the top of the support plate 102 by bolts 302. A sliding rod 303 is slidably inserted into the side of the fixing block 301. A limiting member 6 for limiting is slidably provided on the sliding rod 303. The limiting member includes a spring 304, which is sleeved on the sliding rod 303. One end of the spring 304 is fixedly connected to the side of the fixing block 301, and the other end of the spring 304 is fixedly connected to a fixing plate 306, which is sleeved on the sliding rod 303. The top of 303 is fixed with a limiting block 305 to prevent the fixing plate 306 from falling off. During installation, the fixing plate 306 is pulled to place the first diaphragm 100 and the second diaphragm 101 between the fixing plate 306 and the fixing block 301. When the fixing plate 306 is released, it is driven to retract under the action of the spring 304, so that the fixing plate 306 fixes the first diaphragm 100 and the second diaphragm 101 on the support plate 102. During disassembly, the fixing plate 306 is pulled to disengage the first diaphragm 100 and the second diaphragm 101 from the fixing, thereby separating the first diaphragm 100 and the second diaphragm 101.

[0036] In one embodiment, such as Figure 6 As shown, the support plate 102 includes a reinforcing rib 401 and a plate frame 402. The reinforcing rib 401 is fixedly disposed on the inner wall of the plate frame 402. The reinforcing rib 401 can be a steel plate or a steel mesh to make the structure of the support plate 102 more stable.

[0037] In one embodiment, such as Figures 7-9 As shown, the cleaning mechanism 500 includes a cleaning plate 501. A slider 503 is fixedly provided at the bottom end of the cleaning plate 501. The slider 503 is slidably connected to a groove 502. The groove 502 is opened at the bottom of the first diaphragm 100. A protrusion 504 is fixedly provided on the surface of the cleaning plate 501. A driving member is provided on the back of the cleaning plate 501 to drive the cleaning plate 501 to slide. The driving member causes the cleaning plate 501 to move towards the first diaphragm 100, so that the protrusion 504 on the surface of the cleaning plate 501 applies a pushing force to the first diaphragm 100, causing the first diaphragm 100 to bulge outward and clean the impurities attached to the extrusion block 107 on the surface of the first diaphragm 100.

[0038] In one embodiment, such as Figure 7 and Figure 9As shown, the driving component includes a push plate 505. The top end of the push plate 505 is fixedly connected to the inner wall of the first diaphragm 100 through an elastic membrane 506. An air inlet 507 is provided on the inner top wall of the first diaphragm 100. The air inlet 507 passes through the first diaphragm 100 and communicates with the push plate 505. After the filtration is completed, air is blown or water is added to the air inlet 507. Under the action of the elastic membrane 506, the cleaning plate 501 moves towards the first diaphragm 100.

[0039] The above embodiment discloses a rubber diaphragm filter plate with high support strength. During installation, the connector 203 is inserted into the insertion interface 204, and the connector 203 is fixed inside the insertion interface 204 by the baffle 206. The first diaphragm 100 and the second diaphragm 101 are installed on the support plate 102. The fixing plate 306 is pulled to place the first diaphragm 100 and the second diaphragm 101 between the fixing plate 306 and the fixing block 301. Releasing the fixing plate 306 causes it to retract under the action of the spring 304, thus securing the first diaphragm... The first diaphragm 100 and the second diaphragm 101 are fixedly mounted on the support plate 102. The high-pressure water inlet 105 is used to inject high-pressure water. Water entering through the high-pressure water inlet 105 can push the first diaphragm 100 to bulge away from the support plate 102. The feed inlet 103 is used to feed the filter press. The filter water generated when the filter press is squeezed is discharged through the filter water outlet 104. Both the feed inlet 103 and the filter water outlet 104 are connected to the side of the first diaphragm 100 away from the support plate 100. The hot water outlet 106 is used to introduce hot water or high-temperature steam. Steam, using hot water or high-temperature steam, heats the filter press. The first diaphragm 100 and the second diaphragm 101 are made of waterproof, deformable materials. The first diaphragm 100 and the second diaphragm 101 can bulge away from the support plate 102, thereby causing the sides of the first diaphragm 100 and the second diaphragm 101 away from the support plate 102 to press the filter press. During disassembly, pulling the fixing plate 306 disengages the first diaphragm 100 and the second diaphragm 101, thus separating them. The first diaphragm 100 is then pushed towards... The connector 203 moves to the right, causing it to move toward the disassembly port 205, thereby removing the connector 203 from the disassembly port 205 and removing the first diaphragm 100 from the support plate 102. After the filter press is completed, air or water is blown into the air inlet 507. Under the action of the elastic membrane 506, the cleaning plate 501 moves toward the first diaphragm 100, causing the protrusions 504 on the surface of the cleaning plate 501 to exert a pushing force on the first diaphragm 100, causing the first diaphragm 100 to bulge outward and clean the impurities attached to the extrusion block 107 on the surface of the first diaphragm 100.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
