Description

Technical Field

[0001] This utility model relates to a sector plate of a filter disc. Background Technology

[0002] In the process of coal washing and beneficiation or non-metallic mineral filtration and dewatering, disc filters are generally used for continuous filtration. They are mainly composed of individual sector-shaped discs, each of which is an individual filtration unit. Filter cloth is made and placed on the sector-shaped disc to form a filter chamber. The motor drives the filter disc to rotate clockwise, and the slurry in the filter chamber adheres to the filter disc to form a filter cake in the adsorption zone with the help of the pressure difference created on both sides of the filter medium by the vacuum pump. After the cake is removed, the agitator rotates to prevent solid sedimentation and keeps the filter cake off the liquid surface. Under the action of vacuum, water is further removed.

[0003] During long-term filtration, the sector plates in the filter disc are prone to wear or filter cloth clogging and damage. Therefore, the sector plates need to be disassembled, cleaned or maintained frequently. Otherwise, the filter cloth will be easily damaged, reducing its service life and the overall filtration effect of the filter disc. Utility Model Content

[0004] This utility model mainly solves the technical problems existing in the prior art, thereby providing a sector plate of the filter disc that is easy to disassemble and maintain, facilitates the replacement of filter cloth by users, and effectively improves filtration performance and service life.

[0005] This utility model relates to a fan-shaped plate of a filter disc, comprising a filter substrate and a filter frame detachably sleeved on the outer surface of the filter substrate. The filter substrate includes a panel, a fence surrounding and connected to the upper and lower sides of the panel, a sliding plate and a clamping plate respectively connected to the sides of the panel, and a reinforcing plate connected to the rear end of the panel. The panel surface has columns and through holes inside the fence. A collection cavity is provided on the side of the panel surface facing the reinforcing plate. A drain pipe connected to the collection cavity is provided in the center of the reinforcing plate. An annular cavity is provided in the center of the fence. The filter frame includes two frame pieces attached to the upper and lower sides of the panel. Each frame piece has an annular platform connected to the annular cavity on the side facing the panel. A filter cloth is connected to the center of each frame piece. A core plate is provided behind the frame piece, and the upper and lower sides of the core plate are elastically connected to the outer edges connected to the frame piece.

[0006] Preferably, the panel has a waist groove on the side away from the reinforcing plate, and the core board is connected to a horizontal block for embedding in the waist groove on the side facing the frame. The cooperation between the horizontal block and the waist groove allows the core board to be installed close to the back of the panel, which facilitates the subsequent installation of the frame on the upper and lower sides of the panel.

[0007] Preferably, the outer edge is provided with two rods located on the upper and lower sides of the core board respectively, and the outer edge is connected to the frame with a connecting piece. The connecting piece is a metal spring piece, which makes the frame and the outer edge elastically connected. This allows the user to lift or pry open the frame when the core board and the panel are engaged with each other by the horizontal block and the waist groove, making it convenient for the user to separate or splice the two frames and the panel.

[0008] Preferably, the surface of the annular cavity is provided with locking holes, and there are two or more locking holes evenly distributed in the center of the annular cavity. The side of the annular platform facing the panel is connected with locking posts, and there are two or more locking posts that engage with the locking holes, so that the annular platform below the frame can be embedded into the annular cavity of the panel, and the locking posts can be engaged with the locking holes, thereby fixing the frame and the panel together so that the filter cloth is located on the upper and lower sides of the panel.

[0009] Preferably, there are two or more columns evenly distributed on the upper and lower surfaces of the panel, and the height of the columns is less than the height of the fence. There are two or more through holes that penetrate the panel, so that the filter cloth can be supported by the columns, avoiding the filter cloth from being directly attached to the panel and affecting the filtration effect. At the same time, it prevents the filter cloth from being deformed and damaged by the slurry due to being suspended from the panel. The through holes facilitate the flow of filtered water during filtration.

[0010] Preferably, the panel side clamps are provided with two clamps, and a groove is provided in the center of the clamps. The slide plate is slidably engaged with the groove, and protrusions are connected to both ends of the groove. The slide plate is provided with concave holes that engage with the protrusions at both ends, so that the two filter substrates can slide into the two clamps through the engagement of the slide plate and the groove, and the slide plate is fixedly engaged in the center of the two clamps by the engagement of the protrusions and concave holes, so as to improve the firmness and stability of the connection between the two filter substrates.

[0011] Preferably, the filter substrate has a fan-shaped structure, and the arc length of the end of the panel near the reinforcing plate is smaller than that of the end of the panel away from the reinforcing plate, so as to facilitate the combination and splicing of multiple filter substrates to form a filter disc. The fan-shaped angle of the filter substrate is between 24 degrees and 45 degrees.

[0012] Preferably, the reinforcing plate has a groove inside for fixing the drain pipe, and locking holes are provided through both sides of the reinforcing plate. Ribs are provided on the surface of the reinforcing plate so that the drain pipe can be connected to the reinforcing plate through the groove, and bolts can be passed through the locking holes to connect the fan-shaped plate to the disc filter through the reinforcing plate. The ribs increase the strength of the reinforcing plate.

[0013] The beneficial effects of this utility model are as follows: Since filter cloth is connected to the center of each frame, and annular platforms that fit and engage with the annular cavity are connected to the side of the frame facing the panel, and pillars are evenly distributed on the surface of the panel, the frame and panel are engaged with each other through the annular platforms and the annular cavity. This allows the filter cloth to be fixedly installed on the upper and lower sides of the panel via the frame, and the pillars provide air-supported support for the filter cloth relative to the panel, preventing deformation and damage to the filter cloth due to the pressure of the slurry. This ensures the stability and firmness of the filter cloth during filtration. Furthermore, the filter cloth in the filter frame is connected inside the frame, and the two frames are connected by a core plate and an outer... The filter base is elastically connected to the panel, allowing the filter frame to be removed from both sides of the panel when the filter base is fixed on the disc filter. This facilitates the user's subsequent disassembly and maintenance of the filter cloth inside the frame, enabling cleaning, maintenance, or replacement of the filter cloth. The filter base has clamps and slide plates connected to both sides of the panel, allowing two adjacent filter bases to slide into the groove in the center of the two clamps via the slide plate. This increases the firmness and stability of the multiple filter bases after splicing, effectively improving the overall filtration performance and service life of the spliced ​​filter disc.

[0020] like Figures 1 to 3The illustrated filter disc fan-shaped plate includes a filter substrate 1 and a filter frame 3 detachably sleeved on the outer surface of the filter substrate 1. The filter substrate 1 includes a panel 15, a fence 152 surrounding and connected to the upper and lower sides of the panel 15, a sliding plate 12 and a clamping plate 13 respectively connected to the sides of the panel 152, and a reinforcing plate 11 connected to the rear end of the panel 15. The surface of the panel 15, inside the fence 152, is provided with a column 151 and a through hole 153. A collection cavity 154 is provided on the side of the surface of the panel 15 facing the reinforcing plate 11. The reinforcing plate 11 has a drain pipe 2 connected to the collection chamber 154 in the center. The fence 152 has an annular cavity 17 in the center. The filter frame 3 includes two frame pieces 32 attached to the upper and lower sides of the panel 15. Each frame piece 32 has an annular platform (not labeled) connected to the annular cavity 17 on the side facing the panel 15. Each frame piece 32 has a filter cloth 31 connected to the center. A core plate 33 is provided behind the frame piece 32. The upper and lower sides of the core plate 33 are elastically connected to the outer edge 34 connected to the frame piece 32.

[0021] A waist groove 18 is provided on the side of the panel 15 away from the reinforcing plate 11. A horizontal block (not labeled) for embedding into the waist groove 18 is connected to the side of the core plate 33 facing the frame 32. The cooperation between the horizontal block and the waist groove 18 allows the core plate 33 to be installed close to the back of the panel 15, which facilitates the subsequent installation of the frame 32 on the upper and lower sides of the panel.

[0022] The outer edge 34 is provided with two pieces located on the upper and lower sides of the core board 33 respectively, and the outer edge 34 is connected to the frame 32 by a connecting piece 341. The connecting piece 341 is a metal spring piece, which makes the frame 32 and the outer edge 34 elastically connected. When the core board 33 and the back of the panel are engaged with each other by the horizontal block and the waist groove 18, the user can also lift or pry open the frame 32, making it convenient for the user to separate or splice the two frames 32 and the panel 15.

[0023] The surface of the annular cavity 17 is provided with locking holes 171. There are two or more locking holes 171 evenly distributed in the center of the annular cavity 17. The side of the annular platform facing the panel 15 is connected to locking posts (not labeled). There are two or more locking posts and they are engaged with the locking holes 171, so that the annular platform below the frame 32 can be embedded into the annular cavity 17 of the panel 15, and the locking posts can be engaged with the locking holes 171, thereby allowing the frame 32 and the panel 15 to be engaged and fixed together, so that the filter cloth 31 can be located on the upper and lower sides of the panel 15.

[0024] The column 151 is provided in two or more and is evenly distributed on the upper and lower surfaces of the panel 15. The height of the column 151 is less than the height of the fence 152. The through hole 153 is provided in two or more and penetrates the panel 15, so that the filter cloth 31 can be supported by the column 151, avoiding the filter cloth 31 from being directly attached to the panel 15 and affecting the filtration effect. At the same time, it prevents the filter cloth 31 from being deformed and damaged by the slurry due to being suspended from the panel 15. The through hole 153 is provided to facilitate the flow of filtered water when the filter cloth 31 is filtering.

[0025] Two clamping plates 13 are provided on the side of the panel 15, and a sliding groove 14 is provided in the center of the clamping plate 13. The sliding plate 12 slides with the sliding groove 14, and the two ends of the sliding groove 14 are connected to the protrusions 131. The two ends of the sliding plate 12 are provided with concave holes 121 that engage with the protrusions 131, so that the two filter substrates 1 can slide into the two clamping plates 13 through the cooperation of the sliding plate 12 and the sliding groove 14. The sliding plate 12 is fixedly engaged in the center of the two clamping plates 13 by the engagement of the protrusions 131 and the concave holes 121, so as to improve the firmness and stability of the connection between the two filter substrates 1.

[0026] The filter substrate 1 has a fan-shaped structure, and the arc length of the end of the panel 15 near the reinforcing plate 11 is smaller than that of the end of the panel 15 away from the reinforcing plate 11, so that multiple filter substrates 1 can be combined and spliced ​​around to form a filter disc. The fan-shaped angle of the filter substrate 1 is between 24 degrees and 45 degrees.

[0027] The reinforcing plate 11 has a groove 112 inside for fixing the drain pipe 2, and locking holes 111 are provided through both sides of the reinforcing plate 11. Ribs 113 are provided on the surface of the reinforcing plate 11, so that the drain pipe 2 can be connected to the reinforcing plate 11 through the groove 112, and bolts can be passed through the locking holes 111 to connect the fan-shaped plate to the disc filter through the reinforcing plate 11. The ribs 113 increase the strength of the reinforcing plate 11.

[0028] The filter substrate 1 of the filter disc slides into the groove 14 of another filter substrate 1 via a sliding plate 12. The sliding plate 12 is then inserted into the two clamping plates 13 of the other filter substrate 1 through the engaging engagement of the protrusion 131 and the recess 121, allowing the two filter substrates 1 to be combined and spliced ​​together. Simultaneously, the filter substrate 1 is connected and installed on the disc filter machine via bolts passing through the locking holes 111. Then, the filter frame 3 is fitted onto the outside of the filter substrate 1. The core plate 33 is fitted against the back of the panel 15 through the engagement of the horizontal block and the waist groove 18. Finally, the circumferential surface of the frame 32 is secured by the engaging engagement of the locking post and the locking hole 171. The filter cloth 31, which is embedded in the annular cavity 17 in the center of the fence 152, completely covers the upper and lower surfaces of the panel 15. At the same time, the pillars 151 on the surface of the panel 15 support the filter cloth 31. Then, multiple filter substrates 1 and filter frames 3 are assembled in pairs to form a fan-shaped plate and connected to the disc filter machine, so that they are assembled into a corresponding filter disc for filtering the slurry. This allows the liquid in the slurry to flow through the filter cloth 31 to the surface of the filter substrate 1 and be guided by the panel 15 to flow into the collection chamber 154, and then discharged through the drain pipe 2.

[0029] The beneficial effects of this utility model are as follows: Since filter cloth is connected to the center of each frame, and annular platforms that fit and engage with the annular cavity are connected to the side of the frame facing the panel, and pillars are evenly distributed on the surface of the panel, the frame and panel are engaged with each other through the annular platforms and the annular cavity. This allows the filter cloth to be fixedly installed on the upper and lower sides of the panel via the frame, and the pillars provide air-supported support for the filter cloth relative to the panel, preventing deformation and damage to the filter cloth due to the pressure of the slurry. This ensures the stability and firmness of the filter cloth during filtration. Furthermore, the filter cloth in the filter frame is connected inside the frame, and the two frames are connected by a core plate and an outer... The filter base is elastically connected to the panel, allowing the filter frame to be removed from both sides of the panel when the filter base is fixed on the disc filter. This facilitates the user's subsequent disassembly and maintenance of the filter cloth inside the frame, enabling cleaning, maintenance, or replacement of the filter cloth. The filter base has clamps and slide plates connected to both sides of the panel, allowing two adjacent filter bases to slide into the groove in the center of the two clamps via the slide plate. This increases the firmness and stability of the multiple filter bases after splicing, effectively improving the overall filtration performance and service life of the spliced ​​filter disc.
