Description

Technical Field

[0001] This utility model belongs to the field of diaphragm filter plate technology, specifically relating to an embedded high-pressure diaphragm filter plate with external feeding. Background Technology

[0002] In the field of filtration and separation technology, high-pressure diaphragm filter plates are a key piece of equipment and are widely used in various solid-liquid separation scenarios. The diaphragm filter plate consists of two membranes and a core plate. When an external medium (such as water or compressed air) is introduced into the cavity between the core plate and the membranes, the membranes expand, thereby compressing the filter cavity composed of the diaphragm filter plate and the chamber filter plate, thus achieving better separation and improving the solid content. However, existing diaphragm plate structures are usually heat-fused integral, which requires replacement of the entire plate when damaged. This not only increases equipment maintenance costs but also leads to the waste of a large amount of reusable parts. At the same time, the process of replacing the entire filter plate is cumbersome and requires a long time and manpower, which seriously affects production efficiency. Therefore, this utility model provides an embedded high-pressure diaphragm filter plate with external feeding. Utility Model Content

[0003] The purpose of this utility model is to provide an embedded high-pressure diaphragm filter plate with external feeding to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an embedded high-pressure diaphragm filter plate with external feeding, comprising a diaphragm core plate, wherein a diaphragm sheet is snapped into the inside of the diaphragm core plate, and a plurality of filter beans are provided on the surface of the diaphragm sheet; a pressing water inlet is provided at the bottom of one side of the diaphragm core plate, a pressing water outlet is provided at the top of the other side of the diaphragm core plate, and a feeding hole is provided at the top of the diaphragm core plate.

[0005] In a preferred embodiment, the inner side of the diaphragm core plate is provided with a diaphragm embedding groove adapted to the diaphragm sheet, the diaphragm sheet is provided with mounting strips around its perimeter, and the four sides of the diaphragm embedding groove are provided with limiting grooves adapted to the mounting strips. The diaphragm core plate is made of modified PP material.

[0006] In a preferred embodiment, the diaphragm core plate has four square support point caps symmetrically arranged inside both ends, and each pair of symmetrical support point caps are fixedly connected by screws.

[0007] In a preferred embodiment, the diaphragm core plate is provided with filtrate collection holes at all four corners, each filtrate collection hole is provided with a filtrate channel on one side, and a filtrate outlet hole is provided at the other end of the filtrate channel. The filtrate outlet hole is located between the diaphragm core plate and the diaphragm sheet.

[0008] In a preferred embodiment, the diaphragm core plate has a through hole adapted to the support point cover at the position of the support point cover, and the inner wall of the through hole is provided with a diaphragm inner hook, and the inner wall of the diaphragm embedding groove is provided with a limiting ring adapted to the diaphragm inner hook.

[0009] Compared with the prior art, the beneficial effects of this utility model are: The externally fed embedded high-pressure diaphragm filter plate is embedded in the diaphragm embedding groove of the core plate by the installation strip, forming a detachable embedded structure. When the diaphragm or core plate is damaged, only the damaged part needs to be replaced, without replacing the entire filter plate, which greatly reduces the operating cost and improves the economy of the equipment. This detachable embedded structure makes equipment maintenance more convenient, and the operation of replacing parts is simple and quick, reducing downtime and improving production efficiency. This externally fed embedded high-pressure diaphragm filter plate has an inner hook structure on the diaphragm at the support point that is embedded into the groove of the core plate and squeezed and sealed by the support point cover. This inner hook embedded compression sealing structure can tightly connect the diaphragm and the core plate together to form a reliable seal, effectively preventing material leakage from the support point during the pressing process and ensuring the smooth progress of the filtration process. This externally fed, embedded high-pressure diaphragm filter plate features an external feeding method with no internal feeding holes, significantly enhancing the pressing effect and improving the efficiency of solid-liquid separation. The external feeding design allows for full utilization of the internal space of the diaphragm, increasing the diaphragm area. During pressing, there is no need to worry about tearing at the feed inlet, allowing for greater pressure and achieving high-pressure diaphragm pressing. This results in more thorough extraction of moisture from the material, leading to lower and more uniform moisture content and improved product quality. Attached Figure Description

[0012] The present invention will be further described below with reference to the embodiments.

[0013] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0014] Please see Figure 1-2 This utility model provides an embedded high-pressure diaphragm filter plate with external feeding, including a diaphragm core plate 1. A diaphragm sheet 2 is snapped into the inside of the diaphragm core plate 1. A plurality of filter beans 5 are evenly distributed on the surface of the diaphragm sheet 2. A press water inlet 10 is provided at the bottom of one side of the diaphragm core plate 1, and a press water outlet 11 is provided at the top of the other side of the diaphragm core plate 1. A feed hole 12 is provided at the top of the diaphragm core plate 1. A diaphragm embedding groove 4 adapted to the diaphragm sheet 2 is provided on the inner side of the diaphragm core plate 1. The diaphragm sheet 2 is provided with a feed hole 12 at the top of the diaphragm core plate 1. The mounting strip 401 and the diaphragm embedding groove 4 are provided with limiting grooves that are compatible with the mounting strip 401 on all four sides. The diaphragm core plate 1 is made of modified PP material. The diaphragm core plate 1 has four square support point covers 3 symmetrically arranged inside both ends. Each pair of symmetrical support point covers 3 are fixedly connected by screws 6. The diaphragm core plate 1 has through holes that are compatible with the support point covers 3 at the position of the support point covers 3, and the inner wall of the through holes is provided with membrane inner hooks 13. The inner wall of the diaphragm embedding groove 4 is provided with limiting rings that are compatible with the membrane inner hooks 13. The mounting strips 401 around the diaphragm sheet 2 are aligned with the limiting grooves on the four sides of the diaphragm embedding groove 4 on both sides of the diaphragm core plate 1. The diaphragm sheet 2 is slowly inserted into the diaphragm embedding groove 4. During this process, the inner hook 13 on the diaphragm sheet 2 will initially contact the limiting ring on the inner wall of the diaphragm embedding groove 4, which plays a role in positioning and initial fixation. The support point cover 3 is placed at the corresponding position on the diaphragm core plate 1, so that it passes through the through hole opened at the support point position on the diaphragm core plate 1. Then, screws 6 are used to fix every two symmetrical support point covers 3 to the diaphragm core plate 1. As the screws 6 are tightened, the support point cover 3 squeezes the diaphragm sheet 2, so that the inner hook 13 on the diaphragm sheet 2 fits tightly with the limiting ring on the inner wall of the diaphragm embedding groove 4, forming a reliable sealing structure to ensure that there will be no material leakage or other problems in the subsequent operation. The diaphragm sheet 2 is embedded in the diaphragm mounting groove 4 of the diaphragm core plate 1 through the mounting strip 401, forming a detachable structure. When the diaphragm sheet 2 or the diaphragm core plate 1 is damaged, only the damaged part needs to be replaced, without replacing the entire filter plate, which greatly reduces the operating cost and improves the economy of the equipment. This detachable design makes equipment maintenance more convenient, and the operation of replacing parts is simple and quick, reducing downtime and improving production efficiency. At the same time, it also facilitates regular inspection and maintenance of the filter plate, extending the service life of the equipment.

[0015] In this embodiment, each of the four corners of the diaphragm core plate 1 is provided with a filtrate collection hole 9, and each filtrate collection hole 9 is provided with a filtrate channel 8 on one side. The other end of the filtrate channel 8 is provided with a filtrate outlet hole 7, which is located between the diaphragm core plate 1 and the diaphragm sheet 2. When the material enters the filter chamber of the filter press through the feed hole 12 at the top of the diaphragm core plate 1, the solid particles in the material are intercepted by the filter cloth, while the water begins to pass through the filter cloth. At this time, the space formed between the diaphragm core plate 1 and the diaphragm sheet 2 becomes the prototype of the filtrate flow channel. The water passing through the filter cloth gradually gathers and flows towards the filtrate outlet hole 7. Since the filtrate outlet hole 7 is located between the diaphragm core plate 1 and the diaphragm sheet 2, the water can smoothly enter the filtrate outlet hole 7. The filtrate collected by multiple filtrate outlet holes 7 begins to flow in their respective corresponding filtrate channels 8. The filtrate channels 8 play a role in guiding the flow of filtrate, collecting the dispersed filtrate in an orderly manner. The filtrate flows along the filtrate channels 8 and finally reaches the filtrate collection holes 9 at the four corners of the diaphragm core plate 1, which collect the filtrate transported from each filtrate channel 8. These filtrate collection holes 9 can be connected to other external filtrate collection devices to discharge the collected filtrate from the filter plate, completing the filtrate collection work in the entire filtration process.

[0016] Since there is no feed hole 12 inside the plate, the moisture in the material can be squeezed out more effectively under high pressure, increasing the diaphragm area and making the material moisture content lower and more uniform, thus improving the efficiency of solid-liquid separation and product quality. In the traditional plate-infeed method, the membrane at the feed hole 12 is prone to tearing due to the large pressure during high-pressure pressing. The external feeding design of this utility model completely eliminates this risk, ensures the stable operation of the equipment, and reduces downtime and maintenance time and costs caused by membrane tearing. At the support point, the relevant structure on the diaphragm sheet 2 is tightly fitted with the limiting ring on the inner wall of the diaphragm embedding groove 4 of the diaphragm core plate 1, and a reliable sealing structure is formed by the squeezing action of the support point cover 3. This sealing structure can effectively prevent the material from leaking from the support point during the pressing process, ensuring the smooth progress of the filtration process. At the same time, it can also prevent the leakage of external media when it enters the chamber, ensuring the stability and safety of the pressing process.

[0017] The working principle and usage process of this utility model are as follows: First, align the mounting strips 401 around the diaphragm sheet 2 with the limiting grooves on the four sides of the diaphragm embedding grooves 4 on both sides of the diaphragm core plate 1. Slowly insert the diaphragm sheet 2 into the diaphragm embedding groove 4. During this process, the inner hooks 13 on the diaphragm sheet 2 will initially contact the limiting rings on the inner wall of the diaphragm embedding groove 4, playing a role in positioning and initial fixation. Place the support point pressure cap 3 at the corresponding position on the diaphragm core plate 1, so that it passes through the through hole opened at the support point position on the diaphragm core plate 1. Then, use screws... 6. Fix each pair of symmetrical support point caps 3 to the diaphragm core plate 1. As the screws 6 are tightened, the support point caps 3 compress the diaphragm sheet 2, causing the inner hooks 13 on the diaphragm sheet 2 to fit tightly with the limiting rings on the inner wall of the diaphragm embedding groove 4, forming a reliable sealing structure to ensure that there will be no material leakage or other problems in the subsequent operation. When the material enters the filter chamber of the filter press through the feed hole 12 at the top of the diaphragm core plate 1, the solid particles in the material are intercepted by the filter cloth, while the water begins to pass through the filter cloth. At this point, the space formed between the diaphragm core plate 1 and the diaphragm sheet 2 becomes the initial channel for the flow of filtrate. The water passing through the filter cloth gradually gathers and flows towards the filtrate outlet hole 7. Since the filtrate outlet hole 7 is located between the diaphragm core plate 1 and the diaphragm sheet 2, the water can smoothly enter the filtrate outlet hole 7. The filtrate collected by the multiple filtrate outlet holes 7 begins to flow in their respective corresponding filtrate channels 8. The filtrate channels 8 play a role in guiding the flow of filtrate, orderly gathering the dispersed filtrate. The filtrate flows along the filtrate channels 8 and finally reaches the filtrate collection holes 9 at the four corners of the diaphragm core plate 1, which collect the filtrate delivered from each filtrate channel 8. These filtrate collection holes 9 can be connected to other external filtrate collection devices to discharge the collected filtrate from the filter plate, completing the filtrate collection work in the entire filtration process.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
