Description

Technical Field

[0001] This utility model relates to the field of filter press technology, specifically to a filter press device for a gel-like nucleating agent. Background Technology

[0002] Nucleating agents are widely used in chemical engineering, materials processing, and new energy fields to promote crystal formation and regulate grain structure. Among them, gel-like nucleating agents, due to their high dispersion stability and good adhesion properties, can function more uniformly in the reaction system, and are therefore gradually being promoted in processes such as polymer crystallization modification, drug seed preparation, and synthesis of new energy powder precursors. However, gel-like materials generally have characteristics such as high viscosity, low flowability, and easy clogging, making it difficult to achieve efficient solid-liquid separation in the production process.

[0003] Most existing common filter press equipment is designed for suspensions or low-viscosity slurries, relying on the pore structure of filter cloth or filter plates to achieve solid-liquid separation. When processing gel-like nucleating agents, colloidal particles in the material tend to accumulate rapidly on the surface of the filter cloth, forming a dense layer. This not only significantly increases filtration resistance but also easily causes pore blockage of the filter cloth, leading to increased pressure differential and reduced filtration efficiency. Furthermore, due to severe fouling on the filter cloth surface, frequent shutdowns for cleaning or replacement are required, increasing labor intensity and production costs, and making continuous operation difficult to maintain. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a gel-like nucleating agent pressure filtration device, which aims to alleviate the aforementioned problems to at least some extent.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A gel-like nucleating agent pressure filtration device, comprising: Filter press support; A filter box is mounted on the filter press support, and a filter press plate is provided on the top of the filter box; Two rollers mounted on the filter press support are located on both sides of the filter box. A support plate is provided at the bottom of the filter box, and a filter cloth is wound on one of the rollers, covering the support plate and wound on the other roller; A filter press component mounted on the filter press support is used to move the filter press plate up and down; A drive component located between the filter press support and the reel is used to drive the reel to rotate.

[0006] Preferably, the filter press component includes a top plate connected to the filter press support, the top plate is provided with a hydraulic cylinder, and the telescopic shaft of the hydraulic cylinder is connected to the filter press plate.

[0007] Preferably, the driving component includes a rotating shaft fixed on the reel, the rotating shaft being rotatably connected to the filter press bracket, the filter press bracket being equipped with a motor, and the drive shaft of the motor being connected to the rotating shaft.

[0008] Preferably, the filter press support is provided with a collection box, which is located at the bottom of the support plate.

[0009] Preferably, a cylinder is connected to the filter press support, and the telescopic shaft of the cylinder is connected to the support plate.

[0011] Preferably, a sealing ring is connected to the top of the support plate, and a sealing groove adapted to the sealing ring is opened at the bottom of the side frame and the clearance plate.

[0012] In summary, the present invention has the following main advantages: By installing a filter box, filter plates, and support plates on a filter press support, stable filtration of high-viscosity materials is achieved. The support plates work in conjunction with the rollers, allowing the filter cloth to circulate and rewind between the rollers. When the filter cloth surface becomes clogged, it can be quickly replaced, avoiding frequent shutdowns for cleaning. The filter press components use hydraulic cylinders to drive the filter plates up and down, providing stable and controllable clamping force; the support plates are supported and raised by pneumatic cylinders, which not only enhances the uniformity of force distribution but also facilitates unloading and filter cloth replacement.

[0013] The filter cloth is automatically fed by a motor-driven roller, reducing manual labor. A collection box is located below the support plate to collect the filtrate and prevent leakage and contamination. Furthermore, the clearance plates arranged between the side frames are linked to the linkage mechanism, automatically moving downwards during the filtration process to provide clamping assistance, and returning to their original position when the filter cloth is replaced to prevent residual filter residue from being scraped off, ensuring a clean replacement process. The mating structure of the sealing ring and sealing groove effectively improves the sealing performance of the chamber, preventing material leakage under high pressure. Attached Figure Description

[0016] 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.

[0017] refer to Figures 1-4 This embodiment provides a gel-like nucleating agent pressure filtration device. The device includes a pressure filter support 100, a filter box 101, a roller 103, a support plate 104, a pressure filter component, and a drive component.

[0018] The filter press support 100 serves as the load-bearing frame of the device, supporting the main components and ensuring overall stability during operation. The filter housing 101 is fixedly mounted on the filter press support 100, with a filter press plate 102 installed on its top. The filter press plate 102 can move up and down under the drive of the filter pressing components, applying a filter pressing action to the material inside the filter housing 101 during operation.

[0019] The support plate 104 is located at the bottom of the filter housing 101 and is used to support the filter cloth and the material to be filtered. Two rollers 103 are respectively installed on the filter press supports 100 on both sides of the support plate 104, one of which has the filter cloth pre-wound. The filter cloth unfolds along the surface of the support plate 104 and covers it, then extends to the other roller 103 and is wound around it. This arrangement allows the filter cloth to circulate between the rollers 103. When the filter cloth surface becomes clogged or fouled, the rotation of the roller 103 pulls a new portion of filter cloth onto the surface of the support plate 104, ensuring the continuity of the filtration process.

[0020] The filter press component is mounted on the filter press support 100 and is used to drive the filter press plate 102 to move vertically. During the filter press operation, the filter press plate 102 moves downward, pressing the material against the filter cloth on the support plate 104, thereby achieving solid-liquid separation.

[0021] Furthermore, a drive component is provided between the filter press support 100 and the roller 103. This drive component is connected to the roller 103 and is used to drive the roller 103 to rotate, thereby causing the filter cloth to wind between the two rollers 103. By controlling the drive component, the movement and renewal of the filter cloth can be adjusted according to the usage conditions, thereby improving the stability and efficiency of the filtration process.

[0022] Based on the above embodiments, the filter press component specifically includes a top plate 200 connected to the top of the filter press support 100. The top plate 200 is fixed to the filter press support 100 as a load-bearing member, used to install and support the drive element. A hydraulic cylinder 201 is mounted on the top plate 200, and the hydraulic cylinder 201 is fixed to the mounting holes of the top plate 200 by bolts, with its telescopic shaft extending vertically downwards and firmly connected to the filter press plate 102.

[0023] During operation, the hydraulic cylinder 201, under the control of the hydraulic system, drives its telescopic shaft to extend and retract vertically, thereby raising and lowering the filter press plate 102. When the telescopic shaft of the hydraulic cylinder 201 moves downward, the filter press plate 102 is pressed into the filter housing 101, applying a filtration action to the filter cloth and the material to be processed on the support plate 104; when the telescopic shaft of the hydraulic cylinder 201 retracts, the filter press plate 102 rises, facilitating material unloading or filter cloth replacement.

[0024] Based on the above embodiments, the driving component specifically includes a rotating shaft 202 fixed on the roller 103. Both ends of the rotating shaft 202 are rotatably connected to the filter press bracket 100, allowing the roller 103 to rotate smoothly on the bracket. A motor 203 is mounted on the filter press bracket 100, and the drive shaft of the motor 203 is connected to the rotating shaft 202 via a coupling, thereby achieving power transmission.

[0025] During operation, the motor 203, driven by the control system, rotates the drive shaft, which in turn drives the rotating shaft 202 to rotate, causing the roller 103 to rotate synchronously. When the filter cloth needs to be replaced, the motor 203 is energized to drive the roller 103, causing the filter cloth to gradually unfold from one roller 103 and cover the surface of the support plate 104, before being wound onto another roller 103. In this way, the filter cloth can move between the two rollers 103, allowing for quick replacement of the filtration area when clogging or scaling occurs, ensuring the continuity and stability of the pressure filtration process.

[0026] Based on the above embodiment, the filter press support 100 is provided with a collection box 204, which is located at the bottom of the support plate 104. The collection box 204 is fixedly installed below the filter press support 100 by a support member, with its opening facing upward and arranged opposite to the bottom surface of the support plate 104, for collecting the filtrate that passes through the filter cloth during the filter press process.

[0027] During operation, the material is squeezed by the filter press 102, and the liquid portion passes through the filter cloth and flows down along the support plate 104, eventually flowing into the collection box 204, thus achieving effective solid-liquid separation. The collection box 204 not only prevents the filtrate from leaking and polluting the surrounding environment, but also facilitates the subsequent centralized treatment or recycling of the filtrate.

[0028] Based on the above embodiment, a cylinder 205 is connected to the filter press bracket 100. The cylinder 205 is fixed to the filter press bracket 100 by a mounting seat, and its telescopic shaft extends downward and is connected to the support plate 104.

[0029] During operation, cylinder 205 drives the telescopic shaft to extend and retract under the control system, enabling the support plate 104 to rise and fall vertically. When cylinder 205 extends and retracts, the support plate 104 is lifted, thus providing auxiliary support for the filter cloth and materials; when cylinder 205 retracts, the support plate 104 descends, which is beneficial for unloading or replacing the filter cloth.

[0030] Based on the above embodiments, the filter housing 101 includes two side frames 300, which are fixed to the filter press bracket 100 by screws. A clearance plate 301 is slidably connected between the two side frames 300, and the clearance plate 301 can be raised and lowered in the vertical direction.

[0031] A connecting rod 302 is connected to the support plate 104. The upper end of the connecting rod 302 is rotatably connected to the connecting rod a304, and the other end of the connecting rod a304 is slidably engaged with the connecting ring 303. The connecting ring 303 is mounted on the side frame 300 and can rotate around the mounting point. A connecting rod b305 is also slidably connected to the connecting ring 303, and the other end of the connecting rod b305 is rotatably connected to the clearance plate 301.

[0032] In the initial state, the support plate 104 maintains a predetermined distance from the filter box 101, and the clearance plate 301 is in an elevated state with a large distance between it and the support plate 104, thus reserving space for the replacement of the filter cloth.

[0033] In operation, the telescopic shaft of cylinder 205 retracts, causing the support plate 104 to move upward, thus pressing the filter cloth. At this time, connecting rod 302 moves upward along with the support plate 104, causing connecting rod a304 to push connecting ring 303 to rotate. As connecting ring 303 rotates, connecting rod b305 is pulled to swing, causing the clearance plate 301 to gradually descend, thus approaching the support plate 104 to complete the liquid inlet and pressure filtration operations.

[0034] When the filter cloth needs to be replaced, the telescopic shaft of cylinder 205 extends, causing the support plate 104 to move downwards. The connecting rods and connecting rings 303 then reset, and the clearance plate 301 returns to its raised position. In this way, during the filter cloth replacement process, the clearance plate 301 maintains a sufficient gap with the support plate 104, preventing residual filter material on the filter cloth surface from being scraped off upon contact with the filter housing 101, thus improving the cleanliness and convenience of the filter cloth replacement process.

[0035] Based on the above embodiment, a sealing ring 306 is connected to the top of the support plate 104. The sealing ring 306 is arranged along the edge of the support plate 104 and is fixed by screws or snap-fit, so that it can rise or fall together with the support plate 104 during the filter pressing process.

[0036] At the bottom of the side frame 300 and the clearance plate 301, a sealing groove 307 adapted to the sealing ring 306 is provided. The cross-sectional dimensions of the sealing groove 307 match the sealing ring 306. When the support plate 104 moves upward to the filter press state under the action of the cylinder 205, the sealing ring 306 is precisely embedded in the sealing groove 307, thereby forming a closed structure between the support plate 104 and the filter box 101, preventing material or liquid from leaking from the gap.

[0037] 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.
