Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to an automated water-flushing filter press. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to the material, causing the liquid to seep out. It is a commonly used solid-liquid separation device, mainly used in chemical production, and is still widely used in industries such as chemical, pharmaceutical, metallurgy, dye, food, brewing, ceramics, and environmental protection.

[0003] During the use of a filter press, the filter plates need to be cleaned frequently to maintain the filtration effect. For example, the utility model disclosed in CN204469368U discloses an automatic flushing device for a belt filter press for water treatment, which includes an upper cover plate and a lower bottom plate. The upper cover plate and the lower bottom plate form a sealed cleaning chamber. Inlet and outlet for the mesh belt to move are provided on the left and right sides of the cleaning chamber. A set of cleaning brush rollers is provided in the middle of the cleaning chamber and is connected to a drive device located outside the cleaning chamber. The mesh belt passes through the middle of the set of cleaning brush rollers. Several spray pipes are provided along the inner wall of the cleaning chamber. The structure is simple and the design is reasonable. The same set of pipelines separately uses water and air to clean the surface of the mesh belt, which saves processing costs and ensures the cleaning effect on the surface of the mesh belt, reducing the downtime and frequency of the belt filter press.

[0004] Although the filter press in the above application achieves automatic cleaning of the mesh belt with good cleaning effect and ensures the working efficiency of the belt filter press, it is not thorough enough for impurities with strong adhesion, which affects the subsequent filtration effect of the filter plate. Therefore, an automated water-flushing filter press is proposed to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figure 1-4As shown, the present invention proposes an automated water-flushing filter press, which includes a frame 1, a plurality of filter plates 2 slidably placed inside the frame 1, a hydraulic cylinder 4 installed on one side of the frame 1, and a pressure plate 5 located inside the frame 1 fixedly connected to the output end of the hydraulic cylinder 4.

[0031] The frame 1 is equipped with a rinsing element 3 for rinsing the filter plate 2.

[0032] In this invention, the rinsing component 3 on the frame 1 can rinse the filter plate 2 while also brushing it to improve the cleaning effect.

[0033] In an optional embodiment, the rinsing component 3 includes two sets of crossbeams 31 symmetrically fixed to the frame 1. Sliding frames 32 are slidably connected to the outer sides of the top two crossbeams 31. Support rods 33 are fixedly connected to the outer sides of the two sliding frames 32. A mounting plate 312 is fixedly connected between the two support rods 33. A cylinder 311 is fixedly mounted on the mounting plate 312. A mounting bracket 36 is fixedly connected to the output end of the cylinder 311. Drive shafts 39 are rotatably connected to both sides of the mounting bracket 36, with one end of the drive shaft 39 located inside the mounting bracket 36. A brush plate 38 is fixedly connected. A water guide chamber 37 is fixedly connected to the inner top wall of the mounting frame 36, and several nozzles 310 are connected to the bottom of the water guide chamber 37. A dual-axis motor 313 is fixedly installed at the upper end of the mounting frame 36, and a transmission assembly 314 is provided between the end of the transmission shaft 39 located outside the mounting frame 36 and the output shaft of the dual-axis motor 313. A water tank 316 is placed on the back of the frame 1, and a pump body 315 is fixedly installed on the water tank 316. The outlet and inlet of the pump body 315 are connected to the water guide chamber 37 and the water tank 316 respectively through pipe fittings.

[0034] In this embodiment, the mounting frame 36 lowered by the cylinder 311 can drive a set of brush plates 38 inside the mounting frame 36 to work with the nozzles 310 on the water guide chamber 37 to rinse and brush both sides of the separated filter plate 2, thereby improving the cleaning effect of the filter plate 2 and thus improving the subsequent filtration effect of the filter plate 2.

[0035] It should be noted that control boxes 34 are fixedly installed on both the front and rear sides of the frame 1, and the control boxes 34 are equipped with drive components for driving the sliding frame 32 to move laterally along the horizontal plane. The drive components drive the sliding frame 32 to move laterally along the horizontal plane on the top crossbeam 31. The upper end of the sliding frame 32 is equipped with a contact component for hooking the filter plate 2 to move laterally. The contact component on the sliding frame 32 hooks the filter plate 2 to separate it one by one on the frame 1.

[0036] The mounting bracket 36 is U-shaped, and the pipe connected to the water outlet of the pump body 315 is a flexible hose, so that the flexible hose at the water outlet of the pump body 315 can extend and retract as the water guide chamber 37 rises and falls and moves laterally.

[0037] In addition, the transmission assembly 314 consists of two sets of pulleys and two transmission belts. Each set of pulleys is fixedly connected to one end of the transmission shaft 39 located outside the mounting bracket 36 and the output shaft of the dual-axis motor 313. Each transmission belt is sleeved on each set of pulleys, so that the started dual-axis motor 313 drives one set of transmission shafts 39 on the mounting bracket 36 to rotate synchronously through the transmission assembly 314, thereby driving the brush plate 38 to rotate synchronously. The bristles on the brush plate 38 are soft bristles.

[0038] In an optional embodiment, the drive assembly includes a servo motor 35 fixedly mounted on one side of the control box 34. The output shaft of the servo motor 35 is fixedly connected to a threaded rod 318 with one end penetrating through the top crossbeam 31. A support ring 325 is threadedly connected to the outer side of the threaded rod 318. The upper end of the support ring 325 is U-shaped, and its U-shaped end penetrates through the top crossbeam 31 and is fixedly connected to the sliding frame 32.

[0039] In this embodiment, after the servo motor 35 is started and drives the threaded rod 318 to rotate, it can drive the support ring 325 and the sliding frame 32 connected to the support ring 325 to move laterally along the horizontal plane, thereby driving the support rod 33 and the mounting bracket 36 and brush plate 38 on the mounting plate 312 to move accordingly.

[0040] It should be noted that the inner circumferential wall of the support ring 325 is provided with an internal thread, and the internal thread is adapted to the thread on the outer side of the threaded rod 318, so that the rotating threaded rod 318 can drive the support ring 325 to move and adjust the sliding frame 32 laterally. The upper surface of the top beam 31 is provided with a rectangular through hole for the convex end of the support ring 325 to slide, so that the connection between the support ring 325 and the sliding frame 32 has space for lateral movement.

[0041] In an optional embodiment, the upper end of the sliding frame 32 is U-shaped, and the abutment component includes a support shaft 321 rotatably connected inside the U-shaped end of the sliding frame 32 and passing through the U-shaped end of the sliding frame 32. A drive block 319 located inside the U-shaped end of the sliding frame 32 is fixedly connected to the support shaft 321. An abutment block 320 is fixedly connected inside the U-shaped end of the sliding frame 32. A plug rod 324 is inserted into the outer surface of the U-shaped end of the sliding frame 32. A torsion spring 322 is installed between the T-shaped end of the support shaft 321 and the U-shaped end of the sliding frame 32. A hanging rod 323 that overlaps the plug rod 324 is fixedly connected to the T-shaped end of the support shaft 321.

[0042] In this embodiment, when the U-shaped end of the sliding frame 32 is inserted to support and block the hanging rod 323 on the support shaft 321, the drive block 319 can only rotate towards the side closer to the abutment block 320 after being resisted. Therefore, the servo motor 35, which is started, drives the threaded rod 318 to rotate, causing the support ring 325 and the sliding frame 32 to rotate towards the side away from the servo motor 35, thereby moving the drive block 319 and the abutment block 320 to the front and rear of the filter plate 2. After the front and rear sections of the filter plate 2 are located between the drive block 319 and the abutment block 320, the reverse-driven servo motor 35 can pull a single filter plate 2 towards the side closer to the hydraulic cylinder 4 through the drive block 319 and the abutment block 320 to separate the two filter plates 2 after filtration. This facilitates rinsing the separated filter plates 2 and also facilitates the falling of filter residue between the two filter plates 2.

[0043] When the sliding frame 32 needs to be reset, pull out the plug rod 324 so that the drive block 319 can rotate left and right, and then drive the sliding frame 32 to the position near the pressure plate 5 through the threaded rod 318 to reset.

[0044] It should be noted that the overlap between the hanging rod 323 and the insert rod 324 is J-shaped, so that the J-shaped end of the hanging rod 323 can fit tightly against the insert rod 324, restricting the drive block 319 from rotating away from the abutment block 320. The outer surface of the U-shaped end of the sliding frame 32 is provided with a slot for the insert rod 324 to be inserted, so that the insert rod 324 can be inserted into the U-shaped end of the sliding frame 32 through the slot. At the same time, the insert rod 324 can be pulled out and no longer limit the drive block 319.

[0045] In an optional embodiment, a water pipe 317 is connected to one side of the water tank 316, and a filter element 7 is placed on the front side of the frame 1.

[0046] The filter element 7 includes a placement rack 71 placed on the front side of the frame 1. A slag receiving rack 72 is placed inside the placement rack 71. A filter screen 74 is placed at the upper end of the slag receiving rack 72. A water guide plate 73 is fixedly connected to the inner side of the slag receiving rack 72, and the water guide plate 73 is inclined. The back of the placement rack 71 is connected to the water guide pipe 317, and a drain hole connected to the water guide pipe 317 is opened on the back of the slag receiving rack 72.

[0047] It should be noted that the left and right sides of the slag receiving frame 72 are fixedly connected with the first handle that passes through the placement frame 71, and the back of the filter screen 74 is fixedly connected with the second handle that passes through the slag receiving frame 72 and the placement frame 71 in sequence, so as to facilitate the operator to lift the filter screen 74 and the slag receiving frame 72 respectively.

[0048] The back of the water tank 316 has a water inlet and a drain outlet, and the drain outlet is equipped with a valve, which is connected to the workshop's sewage pipe network.

[0049] In this embodiment, when the water flow during the filter press process needs to be discharged, the slag receiving rack 72 can be placed into the placement rack 71 so that the wastewater from the filter press can flow along the guide rack 6 to the slag receiving rack 72, and then flow along the guide plate 73 and the guide pipe 317 to the water tank 316, and then be discharged along the drain outlet of the water tank 316.

[0050] When the filter plates 2 separate and the filter residue falls along the guide frame 6, the filter screen 74 can be removed so that the filter residue falls into the slag receiving frame 72 and is collected and processed. During the rinsing process of the filter plates 2, the slag receiving frame 72 and the filter screen 74 can be placed in sequence so that the rinsing water can flow along the guide frame 6 into the slag receiving frame 72. After being filtered by the filter screen 74, the water flows along the water guide plate 73 and the water guide pipe 317 into the water tank 316, so that the rinsing water can be filtered and reused.

[0051] The working principle in the above embodiments is as follows:

[0052] When the filter plate 2 needs cleaning, the U-shaped end inserted into the sliding frame 32 supports and blocks the hanging rod 323 on the support shaft 321, thus limiting and blocking the drive block 319. This prevents the drive block 319 from rotating only towards the side closer to the abutment block 320. Therefore, the activated servo motor 35 drives the threaded rod 318 to rotate, causing the support ring 325 and the sliding frame 32 to rotate away from the servo motor 35. This moves the drive block 319 and the abutment block 320 to the front and rear of the filter plate 2, respectively, allowing the filter plate to be cleaned. The front and rear sections of plate 2 are located between drive block 319 and abutment block 320. The servo motor 35, which can be driven in reverse, pulls a single filter plate 2 towards the side closer to hydraulic cylinder 4 through drive block 319 and abutment block 320, separating the two filter plates 2 after filtration. After the filter plate 2 moves between the pressure plate 5 and the previous filter plate 2, the filter residue between the two filter plates 2 can fall off easily. The fallen filter residue can slide along the guide frame 6 into the slag receiving frame 72 where no filter screen 74 is placed, and after being collected, it is lifted and dumped for centralized treatment.

[0053] When it is necessary to clean the filter plate 2, the drive block 319 and the abutment block 320 can pull the single filter plate 2 to move towards the side closer to the hydraulic cylinder 4. When the single filter plate 2 moves between the pressure plate 5 and the previous filter plate 2, the cylinder 311 is activated to lower the mounting frame 36, which drives the brush plate 38 on the mounting frame 36 to cover the single filter plate 2. Then, the dual-shaft motor 313 is activated to drive the transmission shaft 39 through the transmission assembly 314 to drive the brush plate 38 to rotate and brush both sides of the filter plate 2. At the same time, the pump body 315 is activated to deliver the water injected into the water tank 316 to the water guide chamber 37. After being sprayed by the nozzle 310, it works with the brush plate 38 to complete the rinsing and cleaning of the single filter plate 2. Then, the drive block 319 and the abutment block 320 can pull the next filter plate 2 to rinse it. Multiple filter plates 2 can be brushed and cleaned in sequence.

[0054] During the washing process, the water flow can be easily discharged onto the filter screen 74 and the slag receiving rack 72, so that the filter screen 74 can filter the water flow into the slag receiving rack 72. Then, the water flows back into the water tank 316 through the water guide pipe 317 for reuse. When the water becomes turbid, it can be discharged through the drain port on the back of the water tank 316.

[0055] 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 and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
