Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to a filter plate limiting structure for a filter press. Background Technology

[0002] Filter presses are the main filtration equipment in the solid-liquid separation industry and are widely used in chemical, coal washing, food, environmental wastewater treatment and other industries. When unloading the filter cake, the filter plates are pulled apart by pullers installed on the rails on both sides of the filter press main beam to unload the filter cake.

[0003] The existing patent with announcement number CN222550217U discloses a filter plate limiting structure for a filter press, including a filter press body. Multiple filter plates are arranged in a sliding array at the middle of the right end of the filter press body. A hydraulic push plate is provided at the left end corresponding to the multiple filter plates. A set of connecting columns is provided on each of the front and rear sides of the filter press body corresponding to the hydraulic push plate. A sliding groove is opened laterally on the opposite side of the two sets of connecting columns. A sliding component is provided on the front and rear sides of the hydraulic push plate corresponding to the corresponding sliding groove. A limiting structure is provided at the right end of the two sets of connecting columns corresponding to the sliding groove. When the hydraulic push plate pushes the multiple filter plates to fit together completely, the limiting structure can be engaged with the sliding component.

[0004] The patent points out that traditional filter presses generally use a hydraulic locking circuit to maintain the rodless chamber of the pressing cylinder and the system at a certain pressure value to seal the rodless chamber of the pressing cylinder. When the pressure in the rodless chamber of the pressing cylinder and the system decreases, pressure is immediately replenished to keep the filter plates pressed and maintained.

[0005] In this traditional method, the sealing elements of the hydraulic system are prone to wear, resulting in a short pressure holding time. The pump station needs to be frequently started to replenish the pressure of the clamping cylinder. This not only wastes energy, but also increases the pressure on the filter plate due to continuous pressure replenishment, which will greatly reduce the service life of the filter plate over a long period of time. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a filter plate limiting structure for a filter press.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] This utility model discloses a filter plate limiting structure for a filter press, comprising:

[0009] A filter press assembly includes a filter press body and filter plates. The bottom of the filter press body is provided with a base plate. The filter press body has a pressure structure inside. Sliding grooves are provided on both sides of the filter press body. A limit component is provided on one side of the top of the base plate. The limit component includes a mounting plate, a motor, a rotating rod, a bevel gear one, a bevel gear two, a lead screw, a movable plate, a limit rod, and a connecting plate. Multiple filter plates are slidably arranged inside the filter press body.

[0010] As a preferred embodiment of this utility model, the mounting plate is installed on the top side of the base plate, the motor is installed on one side of the mounting plate, and the lead screw is rotatably installed inside the mounting plate.

[0011] As a preferred embodiment of this utility model, the connecting plate is installed on both sides of the top of the mounting plate. The interior of the connecting plate and the mounting plate are both hollow structures and are interconnected. Rectangular through holes are opened on both sides of the connecting plate, and the lead screw is rotatably installed on the top of the interior of both connecting plates.

[0012] As a preferred technical solution of this utility model, the bottom of the lead screw is equipped with the second bevel gear, the outer sides of the rotating rod are equipped with the first bevel gear, the second bevel gear meshes with the first bevel gear, the outer side of the lead screw is threaded with the movable plate, one end of the movable plate passes through the rectangular through hole and is slidably connected to the rectangular through hole, and the limiting rod is fixedly installed on the top side of the movable plate.

[0013] As a preferred embodiment of this utility model, the pressure structure includes a hydraulic cylinder structure, a moving plate, a connecting rod, and a slider. The hydraulic cylinder structure is installed on one side of the inside of the filter press body. The moving plate is installed at the free end of the hydraulic cylinder structure. The connecting rod is installed on both sides of the moving plate. The slider is installed on the outer side of the connecting rod. The slider is slidably connected to the slide groove.

[0014] As a preferred technical solution of this utility model, the slider has a first limiting hole inside, and the slide groove has a second limiting hole on the side near the limiting component. The first limiting hole, the second limiting hole, and the limiting rod are used in cooperation, and the second limiting hole and the limiting rod are positioned relative to each other.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a limiting component, where a motor drives a rotating rod, which in turn drives a lead screw via bevel gear meshing. This causes a movable plate to move a limiting rod and insert it into a limiting hole, effectively restricting the movement of the filter press plate. This design prevents displacement of the filter press plate due to pressure changes, ensuring its stability during filtration and thus guaranteeing the filtration effect and improving the quality of the filtrate. Furthermore, after the hydraulic cylinder assembly pushes the filter press plate, the limiting component keeps it in a limited position, eliminating the need for continuous pressure replenishment by the hydraulic cylinder assembly, significantly reducing energy consumption and production costs. In addition, it avoids the pressure from continuous pressure replenishment on the filter press plate, reducing damage and effectively extending its service life, thus lowering equipment maintenance and replacement costs.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] In the attached diagram, all identical reference numerals refer to the same components.

[0026] like Figure 1-5 As shown, this utility model provides a filter plate limiting structure for a filter press, comprising:

[0027] The filter press assembly 1 includes a filter press body 101 and filter plates 102. A bottom plate 2 is provided at the bottom of the filter press body 101. A pressure structure 3 is provided inside the filter press body 101. Sliding grooves 4 are provided on both sides of the filter press body 101. A limit component 5 is provided on one side of the top of the bottom plate 2. The limit component 5 includes a mounting plate 501, a motor 502, a rotating rod 503, a first bevel gear 504, a second bevel gear 505, a lead screw 506, a movable plate 507, a limit rod 508, and a connecting plate 509. Multiple filter plates 102 are slidably arranged inside the filter press body 101.

[0028] Example 1

[0029] In this embodiment, the mounting plate 501 is installed on the top side of the base plate 2, the motor 502 is installed on one side of the mounting plate 501, and the lead screw 506 is rotatably installed inside the mounting plate 501.

[0030] Furthermore, connecting plates 509 are installed on both sides of the top of the mounting plate 501. The interior of the connecting plate 509 and the mounting plate 501 is hollow and interconnected. Rectangular through holes are opened on both sides of the connecting plate 509. Screws 506 are rotatably installed on the top of the interior of both connecting plates 509.

[0031] Furthermore, a second bevel gear 505 is installed at the bottom of the lead screw 506, and a first bevel gear 504 is installed on both sides of the outer side of the rotating rod 503. The second bevel gear 505 meshes with the first bevel gear 504. A movable plate 507 is threadedly connected to the outside of the lead screw 506. One end of the movable plate 507 passes through a rectangular through hole and is slidably connected to the rectangular through hole. A limit rod 508 is fixedly installed on one side of the top of the movable plate 507.

[0032] Specifically, the motor 502 drives the rotating rod 503 and the first bevel gear 504 to rotate, which in turn drives the second bevel gear 505 and the lead screw 506 to rotate, thereby causing the movable plate 507 and the limiting rod 508 to move longitudinally. This facilitates the insertion of the limiting rod 508 into the limiting hole 6 and the limiting hole 7, thus facilitating the limiting operation of the filter press plate 102.

[0033] Example 2

[0034] In this embodiment, the pressure structure 3 includes a hydraulic cylinder structure 301, a moving plate 302, a connecting rod 303, and a slider 304. The hydraulic cylinder structure 301 is installed on one side of the inside of the filter press body 101. The moving plate 302 is installed on the free end of the hydraulic cylinder structure 301. The connecting rods 303 are installed on both sides of the moving plate 302. The sliders 304 are installed on the outer sides of the connecting rods 303. The sliders 304 are slidably connected to the slide groove 4.

[0035] Furthermore, a limiting hole 6 is provided inside the slider 304, and a limiting hole 7 is provided on the side of the slide groove 4 near the limiting component 5. The limiting hole 6, the limiting hole 7, and the limiting rod 508 are used in conjunction, and the limiting hole 7 and the limiting rod 508 are positioned relative to each other.

[0036] Specifically, the hydraulic cylinder structure 301 drives the moving plate 302 to move laterally, pushing the filter plate 102 to move, and the connecting rod 303 and the slider 304 cooperate to guide the operation.

[0037] Working principle:

[0038] Improving the stability of the filter press plate: By setting a limiting component 5, the motor 502 drives the rotating rod 503, which in turn drives the lead screw 506 to rotate through the meshing transmission of bevel gear 1 504 and bevel gear 2 505. This causes the movable plate 507 to move the limiting rod 508, ultimately allowing the limiting rod 508 to insert into the limiting hole 1 6 and the limiting hole 2 7. This effectively restricts the movement of the filter press plate 102, improves the stability of the filter press plate during operation, prevents displacement of the filter press plate due to pressure changes, and ensures the filtration effect. At the same time, it ensures that the hydraulic cylinder assembly 3 can maintain the limiting state after pushing the filter press plate 102, eliminating the need for continuous pressure replenishment of the hydraulic cylinder assembly 3, greatly reducing energy consumption. Furthermore, when maintaining the filtration state, the filter press plate 102 will not be subjected to pressure from continuous pressure replenishment, reducing damage to the filter press plate 102 and extending its service life.

[0039] Enhancing the stability of the pressure structure: The slider 304 in the pressure structure 3 is slidably connected to the grooves 4 on both sides of the filter press body 101, providing stable guidance for the movement of the moving plate 302. When the hydraulic cylinder structure 301 drives the moving plate 302 to move, the slider 304 slides along the grooves 4, ensuring the straightness of the movement of the moving plate 302, reducing swaying and offset, thereby enhancing the stability of the pressure structure, enabling the pressure to be applied evenly to the filter plate 102, and improving the filtration efficiency and quality.

[0040] Collaborative operation enhances overall performance: The limiting component 5 and the pressure structure 3 work together to improve the overall performance of the filter press. When the pressure structure 3 applies pressure to the filter plate 102 for filtration, the limiting component 5 promptly limits and fixes the filter plate 102. This collaborative operation improves the working efficiency and filtration quality of the filter press, and extends the service life of the equipment.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
