Description

Technical Field

[0001] The present application relates to the field of filter presses, and in particular to a 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 mechanical device that is commonly used in solid-liquid separation equipment. The filter press is the main filtering equipment used in the solid-liquid separation industry and is widely used in municipal environmental protection, food and beverage, chemical pharmaceuticals, petrochemicals, printing and dyeing, papermaking and other related industrial industries.

[0003] In the existing filter press, when in use, multiple filter plates are placed close together, and filter press is performed through the filter plates and filter cloth to discharge the filtrate in the filter residue and form the filter residue into a filter cake. However, in the existing filter press, since the filter plates are not aligned, the adjacent filter plates are prone to deviation, which easily causes the filter residue or filtrate to leak out from between the adjacent filter plates, affecting the filtration process, so it needs to be improved. Utility Model Content

[0004] In order to improve the problem that adjacent filter plates are not aligned, resulting in filter residue or filtrate easily leaking out from between adjacent filter plates when the filter plates are squeezed, the present application provides a filter press.

[0005] The filter press provided in this application adopts the following technical solution:

[0006] A filter press comprises a frame, a plurality of filter press plates are arranged on the frame, support blocks are fixed on the side walls of the filter press plates, a magnet is fixed on the bottom wall of the support block, an iron sheet is arranged on the frame, the magnet and the iron sheet are attracted to each other, a positioning block is fixed on the bottom of the support block, a positioning groove is opened on the frame along the length direction of the frame, and the positioning block is inserted in the positioning groove and can move in the positioning groove.

[0007] By adopting the above technical solution, during installation, the filter press plate is moved to the top of the frame so that the positioning block is aligned with the positioning groove, and then the filter press plate is moved down until the positioning block is inserted into the positioning groove. At this time, the inner wall of the positioning groove abuts against the side wall of the positioning block, thereby limiting the movement of the positioning block along the width direction of the frame, so that the filter press plate will not be offset in the width direction of the frame. The support block is placed on the frame so that the filter press plate is mounted on the frame. At this time, the magnet and the iron sheet are attracted to limit the support block from moving in the vertical direction, so that the filter press plate cannot be offset in the vertical direction, that is, a plurality of filter press plates are aligned in the length direction of the frame.

[0008] When the filter press plate is driven to move, the magnet is attracted to the iron sheet and slides on the iron sheet at the same time. The positioning groove and the positioning block cooperate to play a guiding role, so that the filter press plate will not deviate during the movement until the adjacent filter press plates are squeezed against each other. At this time, the adjacent filter press plates fit together, that is, the edges of the filter press plates fit together and no gaps are easily formed. In the process of mutual squeezing of the filter press plates, the filter residue or filtrate will not leak out from between the adjacent filter plates, that is, the filtration process will not be affected.

[0009] Optionally, a dovetail block is fixed on the bottom wall of the iron sheet, a dovetail groove is opened on the top wall of the frame along the length direction of the frame, one end of the dovetail groove passes through the end of the frame, and the dovetail block is inserted in the dovetail groove and can move in the dovetail groove.

[0010] By adopting the above technical solution, when the filter press plate moves and the magnet keeps sliding on the iron sheet, the iron sheet is easy to wear. At this time, the iron sheet is moved along the length direction of the frame, so that the dovetail block is pulled out of the dovetail slot from one end opening of the dovetail slot, thereby realizing the separation of the iron sheet from the frame. Then, the dovetail block on the new iron sheet is aligned with one end opening of the dovetail slot, and inserted into the dovetail slot from the end opening of the dovetail slot until the dovetail block is completely inserted into the dovetail slot, thereby realizing the installation of the new iron sheet on the frame.

[0011] Optionally, a screw rod is fixed to the end of the frame, a nut is sleeved on the screw rod, the nut is threadedly connected to the screw rod, and the nut close to the side wall of the frame can abut against the end wall of the dovetail block.

[0012] By adopting the above technical solution, when the dovetail block is fully inserted into the dovetail groove, the nut is sleeved on the screw rod and adjusted in the direction of the frame until the nut abuts against the end of the dovetail block on the side close to the frame, thereby limiting the movement of the dovetail block along the length direction of the frame, increasing the stability of the iron sheet installed on the frame, and reducing the possibility that the magnet attracts the iron sheet and drives the iron sheet to move when the filter plate moves.

[0013] Optionally, a limiting hole is provided on the side wall of the positioning block, a limiting block is inserted in the limiting hole, the limiting block can move in the limiting hole, the limiting block is connected to the inner wall of the limiting hole through a limiting spring, the limiting spring is used to push the limiting block out of the limiting hole, a limiting groove is provided on the inner wall of the positioning groove along the length direction of the positioning groove, the limiting block can be inserted in the limiting groove and move in the limiting groove.

[0014] By adopting the above technical solution, during installation, the limit block is manually pressed into the limit hole, so that the limit spring is compressed and the side wall of the positioning block has no protrusion, thereby facilitating the positioning block to be inserted into the positioning groove. When the magnet and the iron sheet are attracted, the limit block also moves to the limit groove. At this time, the end of the limit block is unrestricted, the limit spring restores its deformation, and pushes the limit block away from the positioning block, so that the limit block is inserted into the limit groove, and the inner wall of the limit groove abuts against the side wall of the limit block, limiting the movement of the limit block in the vertical direction, thereby further increasing the stability of the support block mounted on the frame.

[0015] Optionally, a guide surface is provided on the bottom wall of the limiting block, and the guide surface is inclined upward at one end away from the positioning block.

[0016] By adopting the above technical solution, when the positioning block is inserted from the top of the positioning groove, the guide surface will first abut against the frame, and the positioning block continues to move downward. The guide surface plays a guiding role, so that the frame slides relatively on the guide surface, thereby pushing the limit block to squeeze the limit spring and store it in the limit hole, so that there is no need to manually press the limit block during installation, and the operation is more convenient.

[0017] Optionally, the frame is rotatably connected to a rotating rod, the rotating rod is arranged along the width direction of the frame, the rotating rod is sleeved with a push plate, the push plate is threadedly connected to the rotating rod, the push plate is adapted to be inserted in a limiting groove, and can move in the limiting groove along the length direction of the rotating rod.

[0018] By adopting the above technical scheme, when the filter press plate needs to be cleaned or replaced, the rotating rod is driven to rotate. Since the push plate is threadedly matched with the rotating rod, the circumferential side wall of the push plate abuts against the inner wall of the limit groove, which restricts the push plate, so that the push plate will not rotate with the rotation of the rotating rod, thereby causing the push plate to move along the length direction of the rotating rod. When the push plate abuts against the end of the limit block away from the positioning block, the limit block is pushed to move in the direction of the positioning block until the limit block squeezes the limit spring and is completely received in the limit hole. At this time, there is no protrusion on the side wall of the positioning block, which is convenient for the positioning block to be directly moved up and pulled out of the positioning groove, thereby realizing the disassembly of the filter press plate.

[0019] Optionally, one end of the rotating rod extends out of the frame and is fixed with a handle.

[0020] By adopting the above technical solution, the handle provides a force-applying portion for the hand, which facilitates the rotation of the rotating rod, and the operation is convenient, saving time and effort.

[0021] Optionally, a mounting hole is opened on the side wall of the push plate close to the positioning block, an oil-soaked sponge is arranged in the mounting hole, and the side wall of the oil-soaked sponge close to the positioning block abuts against the side wall of the limit block away from the positioning block.

[0022] By adopting the above technical solution, when the push plate squeezes the limit block so that the limit block is received in the limit hole, the oil-immersed sea surface will also contact the side wall of the positioning block, and under the action of the limit spring, there is an extrusion force between the push plate and the limit block, which facilitates the lubricating oil on the oil-immersed sponge to penetrate into the side wall of the positioning block and the end of the limit block, thereby playing a lubricating role, reducing the friction between the push plates and facilitating the positioning block to be pulled out of the positioning groove.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. During installation, move the filter press plate to the top of the frame so that the positioning block is aligned with the positioning groove, and then move the filter press plate down until the positioning block is inserted into the positioning groove. At this time, the inner wall of the positioning groove abuts against the side wall of the positioning block, thereby limiting the movement of the positioning block along the width direction of the frame, so that the filter press plate will not deviate in the width direction of the frame. The support block is placed on the frame so that the filter press plate is mounted on the frame. At this time, the magnet and the iron sheet are attracted to limit the support block from moving in the vertical direction, so that the filter press plate cannot deviate in the vertical direction, that is, several filter press plates are aligned in the length direction of the frame;

[0025] 2. When the filter plate moves and the magnet keeps sliding on the iron sheet, the iron sheet is easy to wear. At this time, move the iron sheet along the length direction of the frame so that the dovetail block is pulled out of the dovetail slot from one end of the dovetail slot, thus separating the iron sheet from the frame. Then align the dovetail block on the new iron sheet with the opening at one end of the dovetail slot, and insert it into the dovetail slot from the end opening of the dovetail slot until the dovetail block is completely inserted into the dovetail slot, thus installing the new iron sheet on the frame.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] The present application embodiment discloses a filter press. Figure 1 and Figure 2 The filter press comprises a frame 10, on which a plurality of filter press plates 20 are arranged parallel to each other. Figure 3 and Figure 4 A support block 30 is fixed on the side wall of the filter press plate 20, a magnet 31 is fixed on the bottom wall of the support block 30, an iron sheet 60 is provided on the top wall of the frame 10, the magnet 31 is attracted to the iron sheet 60, so that the support plate is placed on the frame 10, and the filter press plate 20 is mounted on the frame 10.

[0034] Reference Figure 4 and Figure 5 , a positioning block 32 is fixed at the bottom of the support block 30, and a positioning groove 11 is provided on the frame 10 along the length direction of the frame 10, and the positioning block 32 is inserted in the positioning groove 11 and can move in the positioning groove 11. During installation, the filter press plate 20 is moved to the top of the frame 10 so that the positioning block 32 is aligned with the positioning groove 11, and then the filter press plate 20 is moved down until the positioning block 32 is inserted into the positioning groove 11. At this time, the inner wall of the positioning groove 11 abuts against the side wall of the positioning block 32, thereby limiting the movement of the positioning block 32 along the width direction of the frame 10, so that the filter press plate 20 will not deviate in the width direction of the frame 10. The support block 30 is placed on the frame 10, so that the filter press plate 20 is mounted on the frame 10. At this time, the magnet 31 and the iron sheet 60 are attracted to limit the support block 30 from moving in the vertical direction, so that the filter press plate 20 cannot deviate in the vertical direction, that is, a plurality of filter press plates 20 are aligned in the length direction of the frame 10.

[0035] When the filter press plate 20 is driven to move, the magnet 31 is attracted to the iron sheet 60 and slides on the iron sheet 60. The positioning groove 11 and the positioning block 32 cooperate with each other to play a guiding role, so that the filter press plate 20 will not deviate during the movement until the adjacent filter press plates 20 are squeezed against each other. At this time, the adjacent filter press plates 20 are fitted together, that is, the edges of the filter press plates 20 are fitted together and it is not easy to have gaps, so that when the filter press plates 20 are squeezed against each other, the filter residue or filtrate will not leak out from between the adjacent filter plates.

[0036] Reference Figure 3 and Figure 5 When the filter press plate 20 moves and the magnet 31 continuously slides on the iron sheet 60, the iron sheet 60 is easy to wear. In order to facilitate the replacement of the iron sheet 60, a dovetail block 61 is fixed on the bottom wall of the iron sheet 60. A dovetail groove 13 is opened on the top wall of the frame 10 along the length direction of the frame 10. One end of the dovetail groove 13 passes through the end of the frame 10. The dovetail block 61 is inserted in the dovetail groove 13 and can move in the dovetail groove 13. A screw rod 70 is provided at the end of the frame 10 corresponding to the opening of the dovetail groove 13. The screw rod 70 is horizontally arranged and one end of the screw rod 70 is fixed to the end of the frame 10. A nut 71 is sleeved on the screw rod 70. The nut 71 is threadedly connected to the screw rod 70. The nut 71 is close to the side wall of the frame 10 and can abut against the end wall of the dovetail block 61.

[0037] The iron sheet 60 is driven to move along the length direction of the frame 10, so that the dovetail block 61 is pulled out of the dovetail groove 13 from one end opening of the dovetail groove 13, and the old iron sheet 60 is separated from the frame 10. Then, the dovetail block 61 on the new iron sheet 60 is aligned with one end opening of the dovetail groove 13, and inserted into the dovetail groove 13 from the end opening of the dovetail groove 13 until the dovetail block 61 is completely inserted into the dovetail groove 13, and then the nut 71 is sleeved on the screw rod 70 and adjusted in the direction of the frame 10 until the nut 71 is close to the side of the frame 10 and abuts against the end of the dovetail block 61, thereby limiting the movement of the dovetail block 61 along the length direction of the frame 10, increasing the stability of the iron sheet 60 installed on the frame 10, and realizing the installation of the new iron sheet 60 on the frame 10.

[0038] Reference Figure 4 and Figure 5 In order to increase the stability of the support block 30 placed on the frame 10, a limiting hole 321 is opened on the side wall of the positioning block 32, and a limiting block 40 is inserted in the limiting hole 321. The limiting block 40 can move in the limiting hole 321. A limiting spring 50 is provided in the limiting hole 321. One end of the limiting spring 50 is fixed to the inner wall of the limiting hole 321, and the other end is fixed to the limiting block 40, which is used to push the limiting block 40 out of the limiting hole 321. A limiting groove 12 is opened on the inner wall of the positioning groove 11 along the length direction of the positioning groove 11, and the limiting block 40 can be inserted in the limiting groove 12 and move in the limiting groove 12.

[0039] Reference Figure 4 and Figure 5A guide surface 41 is provided on the bottom wall of the limiting block 40 , and an end of the guiding surface 41 away from the positioning block 32 is inclined upward. When the positioning block 32 is inserted into the top end of the positioning groove 11, the guide surface 41 will first abut against the frame 10, and the positioning block 32 will continue to move downward. The guide surface 41 plays a guiding role, so that the frame 10 slides relatively on the guide surface 41, thereby pushing the limit block 40 to squeeze the limit spring 50 and be received in the limit hole 321. The side wall of the positioning block 32 has no protrusion, which facilitates the positioning block 32 to be inserted into the positioning groove 11. When the magnet 31 is attracted to the iron sheet 60, the limit block 40 also moves to the limit groove 12. At this time, the end of the limit block 40 is unrestricted, the limit spring 50 recovers its deformation, and pushes the limit block 40 in the direction away from the positioning block 32, so that the limit block 40 is inserted into the limit groove 12. The inner wall of the limit groove 12 abuts against the side wall of the limit block 40, limiting the movement of the limit block 40 in the vertical direction, further increasing the stability of the support block 30 mounted on the frame 10.

[0040] Reference Figure 4 and Figure 5 In order to facilitate the removal and replacement of the filter press plate 20, a rotating rod 80 is rotatably connected to the frame 10. The rotating rod 80 is arranged along the width direction of the frame 10 and can rotate on the frame 10 with the central axis of the rotating rod 80 as the axis. One end of the rotating rod 80 extends out of the frame 10 and is fixed with a handle 81. A push plate 90 is sleeved on the rotating rod 80, and the push plate 90 is threadedly connected to the rotating rod 80. The push plate 90 is adapted to be inserted in the limiting groove 12 and can move in the limiting groove 12 along the length direction of the rotating rod 80.

[0041] When the filter press plate 20 needs to be cleaned or replaced, the handle 81 is manually turned to drive the rotating rod 80 to rotate. Since the push plate 90 is threadedly matched with the rotating rod 80, the circumferential side wall of the push plate 90 abuts against the inner wall of the limit groove 12, which restricts the push plate 90, so that the push plate 90 will not rotate with the rotation of the rotating rod 80, so that the push plate 90 will move along the length direction of the rotating rod 80. When the push plate 90 abuts against the end of the limit block 40 away from the positioning block 32, the limit block 40 is pushed to move in the direction of the positioning block 32 until the limit block 40 squeezes the limit spring 50 and is completely received in the limit hole 321. At this time, there is no protrusion on the side wall of the positioning block 32, which is convenient for the positioning block 32 to be directly moved up and pulled out of the positioning groove 11, thereby realizing the disassembly of the filter press plate 20.

[0042] Reference Figure 4 and Figure 5A mounting hole 91 is provided on the side wall of the push plate 90 close to the positioning block 32, and an oil-soaked sponge 110 is provided in the mounting hole 91. The side wall of the oil-soaked sponge 110 close to the positioning block 32 abuts against the side wall of the limit block 40 away from the positioning block 32. When the push plate 90 squeezes the limit block 40 so that the limit block 40 is accommodated in the limit hole 321, the oil-soaked sea surface will also contact the side wall of the positioning block 32, and under the action of the limit spring 50, there is an extrusion force between the push plate 90 and the limit block 40, which facilitates the lubricating oil on the oil-soaked sponge 110 to penetrate the side wall of the positioning block 32 and the end of the limit block 40, playing a lubricating role, reducing the friction between the push plate 90, and facilitating the positioning block 32 to be pulled out of the positioning groove 11.

[0043] The implementation principle of a filter press according to an embodiment of the present application is as follows: during installation, the filter press plate 20 is moved to the top of the frame 10 so that the positioning block 32 is aligned with the positioning groove 11, and then the filter press plate 20 is moved downward until the positioning block 32 is inserted into the positioning groove 11. At this time, the inner wall of the positioning groove 11 abuts against the side wall of the positioning block 32, thereby limiting the movement of the positioning block 32 along the width direction of the frame 10, so that the filter press plate 20 will not deviate in the width direction of the frame 10. The support block 30 is placed on the frame 10, so that the filter press plate 20 is mounted on the frame 10. At this time, the magnet 31 and the iron sheet 60 are attracted to limit the support block 30 from moving in the vertical direction, so that the filter press plate 20 cannot deviate in the vertical direction, that is, a plurality of filter press plates 20 are aligned in the length direction of the frame 10.

[0044] When the filter press plate 20 is driven to move, the magnet 31 is attracted to the iron sheet 60 and slides on the iron sheet 60. The positioning groove 11 and the positioning block 32 cooperate with each other to play a guiding role, so that the filter press plate 20 will not deviate during the movement until the adjacent filter press plates 20 are squeezed against each other. At this time, the adjacent filter press plates 20 are fitted to each other, that is, the edges of the filter press plates 20 are fitted together and it is not easy to have gaps. In the process of mutual squeezing of the filter press plates 20, the filter residue or filtrate will not leak out from between the adjacent filter plates, that is, the filtration process will not be affected.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
