Description

Technical Field

[0001] This utility model relates to the field of pressure filter technology, and in particular to a pressure filter structure for precision filtration of chemical products. Background Technology

[0002] In the production of liquid products in chemical manufacturing, the final step often requires filtration to remove impurities and ensure product quality. However, existing liquid products are often filtered using plate filters, which rely on the liquid's own gravity, resulting in a limited filtration rate and limited filtration efficiency. Impurities are also more likely to fall into the finished product. To address these issues, this application proposes a pressure filter structure for precision filtration of chemical products. Utility Model Content

[0003] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides a pressure filter structure for precision filtration of chemical products. The solution includes a gantry frame, characterized in that: a mounting plate is coaxially fixedly connected to the gantry frame; a filter cartridge is coaxially fixedly connected to the upper end of the mounting plate; a filter cloth made of a special pyrolysis membrane fiber material is coaxially fitted around the outer edge of the filter cartridge; a top cylinder is coaxially fixedly connected to the upper end of the top cylinder; the upper end of a reinforcing member is fixedly connected to the outer edge of the top cylinder; the lower end of the reinforcing member is fixedly connected to the mounting plate; a surrounding cylinder coaxially fitted around the filter cartridge and connected to the flange of the mounting plate; an inlet pipe is fixedly connected to the outer edge of the top cylinder; a drain pipe is fixedly connected to the bottom of the surrounding cylinder; a hydraulic rod is coaxially fixedly connected to the gantry frame; a connecting sleeve is slidably connected to the telescopic end of the hydraulic rod; an elastic connecting member connected to the telescopic end of the hydraulic rod is installed on the connecting sleeve; a pressure plate coaxially inserted into the top cylinder is coaxially fixedly connected to the lower end of the connecting sleeve; and an end cap inserted into the mounting plate is connected to the flange at the lower end of the mounting plate.

[0004] Preferably, the reinforcing member includes a plurality of top blocks evenly distributed around the top cylinder and fixedly connected to the top cylinder, each top block having its upper end fixedly connected to a reinforcing rod, and the lower end of each reinforcing member being fixedly connected to a mounting plate.

[0005] Preferably, the elastic connector includes a support spring arranged coaxially with the connecting sleeve. The upper and lower ends of the support spring abut against the telescopic end of the hydraulic rod and the upper end of the pressure plate, respectively. The outer edge of the connecting sleeve has two vertical grooves arranged symmetrically about its axis. The telescopic end of the hydraulic rod is fixedly connected to two guide blocks that correspond one-to-one with the vertical grooves and are slidably connected. The upper end of the connecting sleeve is threadedly connected to a threaded cap, and the threaded cap has a through hole that slidably engages with the telescopic end of the hydraulic rod.

[0006] The beneficial effects of this utility model are:

[0007] 1. When used, the filter cartridge and filter cloth provided in this application can achieve precise filtration of liquid chemicals, thereby ensuring the quality of the finished product. The filter cloth is made of special pyrolysis membrane fiber material, which can increase its filtration accuracy and improve its weft toughness, ensuring the performance and service life.

[0008] 2. The hydraulic rod, in conjunction with the elastic connector and pressure plate and other related components, can filter liquid products. Under the pressure of the pressure plate, the filtration efficiency can be greatly increased, ensuring production efficiency.

[0009] 3. Since the pressure plate is driven by a hydraulic rod, and the stroke of the hydraulic rod is relatively fixed, an elastic connecting piece is provided to prevent the pressure plate from having a fixed stroke compared to the hydraulic rod. Under the action of the elastic connecting piece, the pressure plate and the connecting sleeve can slide relative to the hydraulic rod. Therefore, when a certain amount of impurities accumulate at the bottom of the filter cartridge, it can prevent the accumulated impurities from affecting the pressure plate or even damaging the filter cartridge.

[0018] The following is in conjunction with the appendix Figure 1-6 The specific embodiments of this utility model will be described in further detail.

[0019] In the first embodiment, the technical solution is as follows: During use, the present application is installed in a suitable area of ​​the workshop via a gantry frame 1. The provided filter cartridge 3, in conjunction with the filter cloth 4, enables precise filtration of liquid chemicals, thereby ensuring the quality of the finished product. The filter cloth 4 is made of a special pyrolysis membrane fiber material, which increases both filtration accuracy and weft toughness, ensuring performance and lifespan. The provided hydraulic rod 10, in conjunction with the elastic connector 12 and pressure plate 13, etc., can perform pressure filtration of liquid products. Under the pressure of the pressure plate 13, the filtration efficiency is greatly increased, ensuring production efficiency. Since the pressure plate 13 is driven by the hydraulic rod 10, and the stroke of the hydraulic rod 10 is relatively fixed, the elastic connector 12 is provided to prevent the pressure plate 13 from having a fixed stroke compared to the hydraulic rod 10. Under the action of the elastic connector 12, the pressure plate 13, together with the connecting sleeve 11, can slide relative to the hydraulic rod 10. Therefore, when a certain amount of impurities accumulate at the bottom of the filter cartridge 3, the accumulated impurities can be prevented from affecting the pressure plate 13 or even damaging the application. The end cap 14 of this application is installed below the mounting plate 2 by means of a flange connection, which is convenient for disassembly, and then the end cap 14 can be removed to clean the accumulated impurities.

[0020] In Example 2, based on Example 1, when this application is in use, under normal circumstances (i.e., when no liquid product is added to the filter cartridge 3), when the hydraulic rod 10 on the gantry 1 extends to its maximum stroke, the pressure plate 13 will also move to its maximum stroke. At this time, the pressure plate 13 is in contact with the upper end of the end cover 14, and the support spring 17 of the elastic connector 12 is in its natural state.

[0021] During pressure filtration, the liquid product to be filtered is first transported to the filter cartridge 3 through the inlet pipe 8 on the top cylinder 5. The liquid then flows through the filter cartridge 3 and filter cloth 4 into the surrounding cylinder 7 and is discharged through the drain pipe 9, while impurities are trapped inside the filter cartridge 3. Furthermore, to enhance the filtration effect, the hydraulic rod 10 is activated and extends at a certain rate, allowing pressure filtration through the pressure plate 13 and increasing the filtration rate. Specifically, when the hydraulic rod 10 is activated, its extension end extends downwards at a set rate. This extension end drives the connecting sleeve 11 and pressure plate 13, among other components, downwards. The pressure plate 13 then compresses the liquid product in the filter cartridge 3, significantly improving the efficiency of the liquid passing through the filter cartridge 3 and filter cloth 4. In other words, pressure filtration greatly improves the filtration efficiency. The filter cloth 4 is made of a special pyrolysis membrane fiber material, which increases both its filtration accuracy and weft toughness, ensuring the effectiveness and lifespan of the filter cloth 4 during pressure filtration.

[0022] Furthermore, as the filter press operation continues for an extended period, a certain amount of impurities will gradually accumulate above the end cap 14. If the pressure plate 13 and the hydraulic rod 10 are fixedly connected, the general stroke of the pressure plate 13 and the hydraulic rod 10 will be fixed. In this case, the hydraulic rod 10 will be blocked by the accumulated impurities during its extension to the maximum stroke, which may cause the hydraulic rod 10 to burst or cause deformation of related components due to excessive pressure. To avoid the above problems, an elastic connector 12 is provided. Under the action of the elastic connector 12, during the extension of the hydraulic rod 10, when the pressure plate 13 comes into contact with the accumulated impurities, the pressure plate 13 is blocked by the impurities and cannot continue to move downward. The telescopic end of the hydraulic rod 10 will continue to move downward relative to the connecting sleeve 11 under the guidance of the guide block 19 and the vertical groove 18 and compress the support spring 17. This ensures the normal extension of the hydraulic rod 10 and avoids bursting or deformation of related components due to excessive pressure.

[0023] In Embodiment 3, based on Embodiment 2, the elastic connector 12, through supporting spring 17, guide block 19, and vertical groove 18, allows the telescopic end of the hydraulic rod 10 to slide relative to the pressure plate 13, preventing the end cap 14 from accumulating too many impurities and affecting the normal use of this application. The threaded cap 20 is threadedly connected to the upper end of the connecting sleeve 11, facilitating the disassembly and assembly of related components during maintenance. The through hole 21 above the threaded cap 20 facilitates the normal operation of the hydraulic rod 10.

[0024] In Example 4, based on Example 1, the reinforcing member 6 provided in this application connects the top cylinder 5 and the mounting cylinder through the reinforcing rod 16 and the top block 15. Under the action of the reinforcing rod 16, the stability and strength of components such as the filter cartridge 3 are ensured, and the service life of this application is improved.
