Description

Technical Field

[0001] This utility model relates to the field of filter press equipment technology, and in particular to an auxiliary filter cake removal device for a filter press. Background Technology

[0002] As a solid-liquid separation device, the filter press is widely used in many industrial fields. Early filtration equipment had low efficiency and poor separation effect. With industrial development, the requirements for the accuracy and efficiency of solid-liquid separation have increased, and traditional equipment can hardly meet the needs. The filter press stands out with its high filtration pressure and good separation effect. However, early filter presses had problems such as low automation, cumbersome operation and difficulty in unloading filter cake, which restricted production efficiency. Therefore, the development of efficient, intelligent and reliable filter presses has become an urgent need for the industry.

[0003] Most existing equipment still relies on manual operation, requiring two people to pull the filter plates on both sides of the filter press to separate adjacent filter plates, allowing the filter cake to fall down. This is not only time-consuming and labor-intensive, increasing labor costs, but also affects the working efficiency of the plate and frame filter press. Furthermore, the filter cake may stick to the surface of the filter plate, preventing it from falling down properly, which affects the automated production of the filter press and results in low production efficiency.

[0004] Existing patent (CN209076134U) discloses an automatic filter cake removal device for a filter press, including a filter press housing. A guide rail is installed inside the housing. A fixed push plate is installed at one end of the guide rail, and a movable push plate is installed at the other end. A hydraulic cylinder is installed on one side of the movable push plate. A filter plate frame is installed between the fixed and movable push plates. Filter plates are installed inside the filter plate frame. First grooves are provided on both sides of the surface of the filter plate frame. A first push rod is installed inside each groove. A first limiting block is installed at one end of the first push rod, and a first spring is installed on one side of the first limiting block. This invention, by setting a discharge rod, uses the first spring to push the first limiting block at one end of the first push rod. A first rotating rod drives the discharge rod away from the filter plate. With the help of a connecting strip on the discharge rod, the filter cake is peeled off the filter plate, which facilitates automated filter cake removal and improves work efficiency.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, in existing devices, the large filter cake is mostly removed by gravity and falls naturally. When there is some residue, it is usually removed by manual tapping. Manual tapping is inefficient, and after the filter cake is removed, the filter plates are usually cleaned manually, which not only wastes manpower but also increases downtime and affects subsequent production capacity.

[0006] Therefore, an auxiliary filter cake removal device for filter presses is proposed. Utility Model Content

[0026] 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 protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] An auxiliary filter cake removal device for a filter press includes a support frame 1. Several filter plates 2 are arranged inside the support frame 1. Connecting blocks 3 are bolted to the top of both sides of the filter plates 2. The bottom of the connecting blocks 3 slides in contact with the top of the support frame 1. Horizontal plates 4 are bolted to both sides of the support frame 1. Slide rails 5 are bolted to the top of the horizontal plates 4. A plate pulling trolley 6 is slidably arranged on the top of the slide rails 5. A high-frequency vibration component 7 is arranged on the top of the plate pulling trolley 6. A cleaning component 8 is arranged on the right side of the plate pulling trolley 6.

[0029] The high-frequency vibration assembly 7 includes a telescopic cylinder 71, the bottom of which is bolted to the top of the pull plate trolley 6. A mounting block 72 is bolted to the top of the telescopic cylinder 71. A high-frequency vibration motor 73 is installed inside the mounting block 72. An anti-slip and wear-resistant pad 74 is installed on the top of the mounting block 72. An extension plate 75 is bolted to the side of the connecting block 3 away from the filter press plate 2. The bottom of the extension plate 75 contacts the top of the anti-slip and wear-resistant pad 74.

[0030] In this embodiment: the filter press uses an auxiliary filter cake removal device. The device is based on a frame support 1 welded from high-strength steel, which is equipped with several filter plates 2. Each filter plate 2 has connecting blocks 3 bolted to its top sides. The bottom of the connecting blocks 3 is smoothed, allowing for tight and smooth sliding contact with the top of the support 1, facilitating the movement of the filter plates 2 during filtration and unloading. Horizontal plates 4 are welded to both sides of the support 1, and high-precision linear guide rails 5 are bolted to the top of the horizontal plates 4. This ensures that the motor-driven plate-pulling trolley 6 can smoothly reciprocate along a precise trajectory. The plate-pulling trolley 6 can pull apart the filter plates 2 that need filter cake removal, causing the filter cake to fall off. If the filter cake adheres to the filter plate 2, a high-frequency vibration component 7 is installed on the top of the plate-pulling trolley 6. Vibration assistance is provided to the filter press plate 2 at a suitable position to help the filter cake fall off. A cleaning component 8 is provided on the right side of the plate pulling trolley 6 to clean the filter press plate 2 after the filter cake falls off, ensuring its filtration performance. The high-frequency vibration component 7 set at the top of the plate pulling trolley 6 is used to assist the filter cake to fall off the filter press plate 2. The bottom of the telescopic cylinder 71 in the high-frequency vibration component 7 is bolted to the top of the plate pulling trolley 6. The telescopic cylinder 71 can extend and retract up and down, driving the mounting block 72 bolted to the top to move up and down. The high-frequency vibration motor 73 inside the mounting block 72 generates high-frequency vibration after starting. The anti-slip wear-resistant pad 74 on the top of the mounting block 72 contacts the bottom of the extension plate 75 bolted to the side of the connecting block 3 away from the filter press plate 2. In this way, the high-frequency vibration can be transmitted to the filter press plate 2, causing the filter cake to fall off.

[0031] Specifically, such as Figure 1 , Figure 4 As shown, the cleaning assembly 8 includes a fixing plate 81, which is bolted to the pull plate trolley 6 on the side near the pull plate trolley 6.

[0032] Specifically, such as Figure 4 As shown, a water supply pipe 82 is provided inside the fixed plate 81. The other end of the water supply pipe 82 extends to the bottom of the support frame 1. A stabilizing member 83 is bolted to the side of the fixed plate 81 away from the pull plate trolley 6. Two locking blocks 84 are bolted to the left side and top of the stabilizing member 83. The inner wall of the locking block 84 is in contact with the surface of the water supply pipe 82.

[0033] Specifically, such as Figure 4 As shown, a rotating nozzle 85 is rotatably connected to the left side of the water supply pipe 82, and the rotating nozzle 85 is used in conjunction with the filter press plate 2. A water delivery hose 86 is fixedly connected to the top of the water supply pipe 82.

[0034] In this embodiment: the cleaning assembly 8 plays an important role in the chemical raw material filtration production line. The cleaning assembly 8 mainly consists of a fixed plate 81, a water supply pipe 82, a stabilizing component 83, a rotating nozzle 85, and a water delivery hose 86. The fixed plate 81 is made of aluminum alloy, which has a light weight and high strength. Its side near the pull plate trolley 6 is firmly bolted to the pull plate trolley 6 to ensure synchronous movement during the movement of the pull plate trolley 6. The water supply pipe 82 is a high-strength plastic pipe installed inside the fixed plate 81, and its other end extends to the bottom of the support frame 1 to facilitate water delivery and cleaning of the filter press plates 2. The stabilizing component 83 is bolted to the fixed plate by welding. On the side away from the pull plate trolley 6, there are two locking blocks 84 on its left side and top, which are bolted together. The inner wall of the locking block 84 is in close contact with the surface of the water supply pipe 82, which firmly fixes the water supply pipe 82. The rotating nozzle 85 is made of stainless steel and is rotatably connected to the left side of the water supply pipe 82 through a rotary joint. Its spray hole design has been optimized to produce a uniform and wide-coverage water spray effect. It matches the position and size of the filter press plate 2 to achieve comprehensive cleaning of the filter press plate 2. The water supply hose 86 is a pressure-resistant rubber hose. One end of it is fixedly connected to the top of the water supply pipe 82, and the other end is connected to an external high-pressure water source, which can stably deliver cleaning water to the rotating nozzle 85.

[0035] Specifically, such as Figure 3 As shown, anti-slip and wear-resistant pad 74 has anti-fall rubber strips 9 on both sides of its top.

[0036] Specifically, such as Figure 3 As shown, the front and rear sides of the telescopic cylinder 71 are both bolted with fixing blocks 10, and the bottom of the fixing blocks 10 is bolted to the top of the pull plate trolley 6.

[0037] In this embodiment: the relevant components of the high-frequency vibration assembly 7 ensure the effective transmission of vibration and the stability of the equipment. The anti-slip and wear-resistant pad 74 is made of rubber and has good anti-slip and wear-resistant properties. Anti-detachment rubber strips 9 are glued to its top two sides. These anti-detachment rubber strips 9 can prevent the extension plate 75 on the connecting block 3 from slipping off the anti-slip and wear-resistant pad 74 during vibration, ensuring that the high-frequency vibration can be stably transmitted to the filter press plate 2. The telescopic cylinder 71 is pneumatically controlled, and its bottom is bolted to the top of the pull plate trolley 6. At the same time, the telescopic cylinder 71 is divided into front and rear sides. The fixed block 10 is bolted to the bottom of the plate trolley 6. The fixed block 10 is also bolted to the top of the plate trolley 6. The fixed block 10 can enhance the stability of the telescopic cylinder 71 and prevent it from shaking or shifting during operation. It ensures that the telescopic cylinder 71 can accurately control the up and down movement of the mounting block 72. The mounting block 72 has a certain weight and strength. A high-frequency vibration motor 73 is fixedly installed inside it by bolts. The vibration generated by the high-frequency vibration motor 73 is transmitted to the extension plate 75 on the filter press plate 2 through the mounting block 72 and the anti-slip wear-resistant pad 74, which in turn drives the filter press plate 2 to vibrate to assist the filter cake to fall off.

[0038] Specifically, such as Figure 1 As shown, the bottom of the support frame 1 is bolted with four support feet 11. The front side of the inside of the support frame 1 is provided with a feed pipe 12. The rear side of the feed pipe 12 extends into the inside of the support frame 1 and is fixedly connected to a fixed baffle 13.

[0039] Specifically, such as Figure 5 As shown, a telescopic electric cylinder 14 is provided on the rear side inside the support frame 1, and a push plate 15 is bolted to the front side of the telescopic electric cylinder 14.

[0040] In this embodiment: During the overall operation of the chemical raw material filtration production line, the components at the bottom and inside of the support frame 1 ensure the stable operation of the device and the effective filtration of materials. The bottom of the support frame 1 is equipped with cast iron support feet 11, which are firmly connected to the bottom of the support frame 1 by welding, providing stable support for the entire device. The front side of the inside of the support frame 1 is equipped with a feed pipe 12, which extends to the inside of the support frame 1 and is connected to a fixed baffle 13 by welding, allowing the material to enter between the filter plates 2 for filtration. The rear side of the inside of the support frame 1 is equipped with an electrically controlled telescopic cylinder 14, and the front side of the cylinder is bolted with a push plate 15 with a smooth surface. The telescopic cylinder 14 can precisely control the forward and backward movement of the push plate 15, pushing the filter plates 2 to squeeze each other during the filtration process to achieve efficient filtration. During the unloading process, the push plate 15 moves backward, providing sufficient space for the plate pulling trolley 6 to facilitate the removal of the filter cake.

[0041] Working distance: The auxiliary filter cake removal device of this filter press is based on a frame-type support frame 1 welded from high-strength steel. Support feet 11 are welded to the bottom of the frame to provide stable support for the device. A feed pipe 12 is installed on the front side inside the support frame 1, extending to the rear and welded to a fixed baffle 13. Material enters through this pipe and is filtered between the filter plates 2. An electrically controlled telescopic cylinder 14 is also installed on the rear side inside the cylinder, with a smooth rectangular push plate 15 bolted to its front. During filtration, the cylinder pushes the filter plates 2 to compress and achieve efficient filtration. During unloading, the push plate 15 moves backward to facilitate the removal of material. The trolley 6 provides space for the filter plates. Each filter plate 2 has connecting blocks 3 bolted to its top sides. The bottom of the connecting blocks 3 is smooth, allowing for tight and smooth sliding against the top of the support frame 1, facilitating movement of the filter plates 2 during filtration and unloading. Horizontal plates 4 are welded to both sides of the support frame 1. High-precision linear guide rails 5 at the top of the horizontal plates 4 ensure that the motor-driven trolley 6 slides smoothly back and forth along a precise trajectory. The trolley 6 can pull apart the filter plates 2 from which the filter cake needs to be removed, causing the filter cake to fall off. If the filter cake is stuck, the high-frequency vibration component 7 at its top can assist in its removal. The bottom of the telescopic cylinder 71 is bolted to the top of the pull plate trolley 6. Stability is enhanced by fixing blocks 10 on the front and rear sides. The telescopic cylinder 71 is pneumatically controlled, allowing the top mounting block 72 to move up and down. A high-frequency vibration motor 73 is fixed inside the mounting block 72. The top anti-slip and wear-resistant pad 74 contacts the bottom of the extension plate 75 of the filter press plate 2 connecting block 3. Anti-detachment rubber strips 9 are located on both sides of the anti-slip and wear-resistant pad 74 to ensure stable transmission of high-frequency vibration to the filter press plate 2, causing the filter cake to fall off. The cleaning assembly 8 on the right side of the pull plate trolley 6 ensures the filtration performance of the filter press plate 2. The fixed plate 81 of the 8 is made of aluminum alloy and is bolted to the pull plate trolley 6 for synchronous movement; the high-strength plastic water supply pipe 82 installed inside extends to the bottom of the support frame 1; the stabilizing component 83 fixes the water supply pipe 82 through the clamp 84; the stainless steel rotating nozzle 85 is connected to the water supply pipe 82 through the rotating joint, and the optimized spray hole can thoroughly clean the filter press plate 2; the pressure-resistant rubber water supply hose 86 connects the water supply pipe 82 to the external high-pressure water source to stably deliver cleaning water. The entire device achieves the functions of chemical raw material filtration, filter cake removal and filter plate 2 cleaning through the coordinated work of various components.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
