Description

Technical Field

[0001] This utility model belongs to the technical field of plate and frame filter presses, and in particular relates to a plate and frame filter press with a filter plate replacement structure. Background Technology

[0002] Plate and frame filter presses, as key equipment for solid-liquid separation, are widely used in chemical, environmental protection, mining, food and other fields. Their core working unit is an array of filter chambers composed of multiple alternating filter plates and frames. During long-term operation, filter cloth clogging, filter plate wear or damage are inevitable, requiring periodic or emergency replacement of the filter plates to maintain equipment efficiency and filtration quality. However, existing plate and frame filter press filter plate replacement structures still have some problems.

[0003] For example, the utility model patent with publication number CN221673512U includes two support platforms, with two slide rails fixed between the support platforms. Several first sliders are slidably arranged on one of the slide rails, and several second sliders corresponding to the positions of the first sliders are slidably arranged on the other slide rail. Filter plates are arranged between the first sliders and second sliders that are in opposite positions. This utility model uses multiple bolts to fix the filter plates. The bolt fixing method requires tools to operate during disassembly and installation, and the operation process is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a plate and frame filter press with a filter plate replacement structure. By setting a quick-release component, specifically, when the hydraulic cylinder pushes the filter plate to move, due to the restriction of the positioning pin, the slider can only slide on the inner wall of the first slide groove, while the outer surface of the positioning pin slides on the inner wall of the second slide groove. When the filter plate needs to be replaced, the positioning pin is pulled out of the inner wall of the positioning hole, which releases the restriction of the slider, allowing the slider to disengage from the first slide groove and remove the filter plate. This solves the problem that existing plate and frame filter presses use multiple bolts to fix the filter plate, resulting in time-consuming and labor-intensive disassembly and installation processes with low efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a plate and frame filter press with a filter plate replacement structure, comprising a support frame, a quick-release assembly, and a cleaning assembly. The support frame includes a hydraulic cylinder fixedly connected to the left side of the support frame. The support frame contains a plurality of filter plates. The filter plates are characterized by having connecting frames fixedly connected to both their front and back sides. The quick-release assembly is installed at the bottom of the connecting frames for quick assembly and disassembly of the filter plates. The quick-release assembly includes: A slide groove is formed on the top front and back of the support frame. A slider is fixedly connected to the bottom of the connecting frame. The outer surface of the slider is slidably connected to the inner wall of the slide groove. Slide groove two is provided on both the front and back sides of slide groove one; The positioning hole is opened on the front of the slider, and the positioning pin is provided on the front of the second slide groove. The back of the positioning pin passes through the second slide groove and is inserted into the inner wall of the positioning hole. The cleaning component is installed on top of the support frame and is used for cleaning the filter plates.

[0006] Furthermore, a hoisting interface is fixedly connected to the top of the filter plate.

[0007] Furthermore, a slot is formed on the outer surface of the positioning pin, a locking cap is inserted into the back of the positioning pin, and an elastic block is fixedly connected to the inner wall of the locking cap, with the outer surface of the elastic block in contact with the inner wall of the slot.

[0008] Furthermore, the cleaning component includes: A support block, with an electric push rod fixedly connected to the top of the support block, and a spray frame fixedly connected to the bottom of the electric push rod; A spray pipe is fixedly connected inside the spray frame, and several spray nozzles are fixedly connected to the left side of the spray pipe. A drive mechanism is used to drive the support block to move for cleaning the filter plates at different positions.

[0009] Furthermore, the drive mechanism includes four support frames II, which are fixedly connected to the top four corners of the support frame I. Two support frames II are rotatably connected to lead screws on their corresponding sides. Synchronous pulleys are fixedly connected to the right side of the lead screws. The two synchronous pulleys are connected by a synchronous belt drive. A motor is fixedly connected to the left side of the support frame II. The right output end of the motor is fixedly connected to the left side of the lead screw located on the front side via a coupling.

[0010] Furthermore, two limiting rods are fixedly connected to the top of the spray frame, and the outer surface of the limiting rods is slidably connected to the inside of the support block.

[0011] This utility model has the following beneficial effects: 1. This utility model improves installation and disassembly efficiency by setting up a quick-release component. Specifically, when the hydraulic cylinder pushes the filter plate to move, the slider can only slide on the inner wall of the first slide groove due to the restriction of the positioning pin. The outer surface of the positioning pin slides on the inner wall of the second slide groove. When the filter plate needs to be replaced, the positioning pin is pulled out of the inner wall of the positioning hole, which can release the restriction of the slider, allowing the slider to disengage from the first slide groove and the filter plate to be removed.

[0012] 2. This utility model, by setting up a cleaning component, specifically, when the filter plate needs to be cleaned, the motor is started. Due to the action of the synchronous pulley and synchronous belt, the two lead screws are driven to rotate simultaneously, thereby driving the support block to move. The support block is moved in front of the filter plate that needs to be cleaned. The electric push rod is started to push the spray frame down. Water is connected to an external water source through the water injection pipe and sprayed out from the spray nozzle through the spray pipe to rinse the filter plate, thus realizing automated continuous cleaning.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figures 1-5 As shown, this utility model has the following two specific embodiments.

[0019] Example 1 This utility model relates to a plate and frame filter press with a filter plate replacement structure, comprising a support frame 1, a quick-release assembly 2, and a cleaning assembly 3. The support frame 1 includes a hydraulic cylinder 11, which is fixedly connected to the left side of the support frame 1. A plurality of filter plates 12 are disposed inside the support frame 1. The key feature is that connecting frames 121 are fixedly connected to both the front and back of the filter plates 12. The quick-release assembly 2 is installed at the bottom of the plurality of connecting frames 121 for quick disassembly and assembly of the filter plates 12. The quick-release assembly 2 includes: Slide 21 is formed on the top front and back of the support frame 1. A slider 211 is fixedly connected to the bottom of the connecting frame 121. The outer surface of the slider 211 is slidably connected to the inner wall of the slide 21. Slide groove 22 is provided on both the front and back sides of slide groove 1 21; Positioning hole 23 is provided on the front of slider 211. Positioning pin 231 is provided on the front of slide groove 22. The back of positioning pin 231 passes through slide groove 22 and is inserted into the inner wall of positioning hole 23. The cleaning component 3 is installed on top of the support frame 1 and is used for cleaning the filter plate 12.

[0020] like Figures 1-3 As shown, by setting up the quick-release component 2, specifically when the hydraulic cylinder 11 pushes the filter plate 12 to move, due to the restriction of the positioning pin 231, the slider 211 can only slide on the inner wall of the first slide groove 21, and the outer surface of the positioning pin 231 slides on the inner wall of the second slide groove 22. When the filter plate 12 needs to be replaced, the positioning pin 231 is pulled out from the inner wall of the positioning hole 23, which can release the restriction of the slider 211, allowing the slider 211 to disengage from the first slide groove 21 and the filter plate 12 to be removed, thus improving the efficiency of installation and disassembly.

[0021] The top of the filter plate 12 is fixedly connected to a hoisting interface 122.

[0022] The outer surface of the positioning pin 231 has a slot 232, and a locking cap 233 is inserted into the back of the positioning pin 231. An elastic block 234 is fixedly connected to the inner wall of the locking cap 233, and the outer surface of the elastic block 234 contacts the inner wall of the slot 232.

[0023] The lifting interface 122 on the top of the filter plate 12 facilitates the use of lifting equipment to move heavy filter plates, reducing labor intensity and improving replacement efficiency; the slot 232 of the positioning pin 231 cooperates with the elastic block 234 in the locking cap 233, which can quickly lock or loosen the positioning pin without tools, making the operation simple and providing reliable anti-loosening protection.

[0024] Example 2 The difference from Embodiment 1 is that this embodiment discloses a cleaning component 3: Cleaning component 3 includes: Support block 32, electric push rod 321 is fixedly connected to the top of support block 32, and spray frame 322 is fixedly connected to the bottom of electric push rod 321; Spray pipe 323 is fixedly connected inside spray frame 322, and several nozzles 324 are fixedly connected to the left side of spray pipe 323; The drive mechanism is used to drive the support block 32 to move for cleaning the filter plate 12 at different positions.

[0025] The drive mechanism includes four support frames 31. The support frames 31 are fixedly connected to the top four corners of the support frame 1. Two support frames 31 are rotatably connected to lead screws 311 on their corresponding sides. The right side of the lead screws 311 is fixedly connected to synchronous pulleys 312. The two synchronous pulleys 312 are connected by synchronous belt drive. The left side of the support frame 31 is fixedly connected to a motor 313. The right output end of the motor 313 is fixedly connected to the left side of the lead screw 311 located on the front through a coupling.

[0026] like Figures 4-5 As shown, by setting up the cleaning component 3, specifically when the filter plate 12 needs to be cleaned, the motor 313 is started. Due to the action of the synchronous pulley 312 and the synchronous belt, the two lead screws 311 are driven to rotate, thereby driving the support block 32 to move. The support block 32 is moved in front of the filter plate 12 that needs to be cleaned. The electric push rod 321 is started to push the spray frame 322 down. The water source is connected through the water injection pipe 325, and the water is sprayed out from the spray nozzle 324 through the spray pipe 323 to rinse the filter plate 12, realizing automated continuous cleaning.

[0027] Two limiting rods 33 are fixedly connected to the top of the spray frame 322, and the outer surface of the limiting rods 33 is slidably connected to the inside of the support block 32.

[0028] The limiting rod 33 effectively restricts the swing and rotation of the spray frame 322 during the lifting process, ensuring the stability of its vertical lifting and lowering, and ensuring that the nozzle 324 is always aligned with the target cleaning area, thereby improving the cleaning accuracy.

[0029] A specific application of this embodiment is as follows: During use, the hydraulic cylinder 11 pushes the filter plate 12 to move. Due to the restriction of the positioning pin 231, the slider 211 can only slide on the inner wall of the first slide groove 21, and the outer surface of the positioning pin 231 slides on the inner wall of the second slide groove 22. When the filter plate 12 needs to be replaced, the locking cap 233 on the back of the positioning pin 231 is pulled out, so that the elastic block 234 is disengaged from the slot 232, releasing the lock of the positioning pin 231. Then, the positioning pin 231 is pulled out from the inner wall of the positioning hole 23, which releases the restriction of the slider 211, allowing the slider 211 to disengage from the first slide groove 21 and the filter plate 12 to be removed. The same principle applies during installation. The slider 211 is placed into the inner wall of the first slide groove 21, the positioning pin 231 is inserted into the positioning hole 23, and the locking cap 233 is inserted into the back of the positioning pin 231. The slot 232 engages with the elastic block 234 inside the locking cap 233, allowing for quick locking or unlocking of the positioning pin without tools. The top lifting interface 122 of the filter plate 12 facilitates connection with lifting equipment, reducing the workload of workers by lifting the filter plate 12. When the filter plate 12 needs to be cleaned, the motor 313 is started. Due to the action of the synchronous pulley 312 and the synchronous belt, the two lead screws 311 are driven to rotate, thereby moving the support block 32. The support block 32 is moved to the front of the filter plate 12 that needs to be cleaned. The electric push rod 321 is started to push the spray frame 322 down. Water is connected to an external water source through the water injection pipe 325 and sprayed from the nozzle 324 through the spray pipe 323 to rinse the filter plate 12, achieving automated continuous cleaning.
