[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] This embodiment provides an epoxy resin purification device, see [link]. Figure 1-6 Specifically, including:

[0032] The chamber 1 and filter plates 2 are movably inserted into the inner cavity of the chamber 1 for purifying epoxy resin. Multiple sets of filter plates 2 are provided for multiple filtrations to achieve better purification results. An outlet 104 is provided on the outer wall of the chamber 1, and a cleaning assembly is provided on the inner wall of the outlet 104. This cleaning assembly includes:

[0033] The fixed block 3 and the scraper 301 are fixedly connected to the inner wall of the outlet 104. The scraper 301 is fixedly set at the bottom of the fixed block 3. When in use, the user pulls the filter plate 2 to the right so that the outer wall of the scraper 301 contacts the surface of the filter plate 2. The scraper 301 scrapes off the impurities on the surface of the filter plate 2. The scraper 301 is set outside the box 1 to prevent the scraped impurities from falling into the box 1 and affecting the quality of epoxy resin purification.

[0034] The collection box 4 is set at the bottom of the fixing block 3 by a snap-fit ​​unit. The collection box 4 is used to collect the impurities that fall from the filter plate 2. When the impurities on the surface of the filter plate 2 are scraped off by the scraper 301, the filter plate 2 is moved out of the box 1. At this time, the impurities scraped off by the scraper 301 fall downwards under the action of gravity and fall into the collection box 4 for easy collection and subsequent processing.

[0035] The snap-fit ​​unit includes a limiting groove 401 and a connecting block 5. The limiting groove 401 is formed on the outer wall of the collection box 4. The connecting block 5 is fixedly set at the bottom of the fixing block 3. The outer wall of the connecting block 5 has a groove. The inner wall of the groove on the outer wall of the connecting block 5 is movably snapped with the limiting block 501. The limiting block 501 is engaged and snapped into the corresponding limiting groove 401. In use, the user presses the limiting block 501 into the connecting block 5 to retract it into the connecting block 5. Furthermore, by aligning the groove on the top of the collection box 4 with the connecting block 5 and pushing the collection box 4 upward, the connecting block 5 is inserted into the inner cavity of the collection box 4. When the limiting block 501 is aligned with the limiting groove 401, the limiting block 501 is pushed outward by the pushing force of the compression spring 502, so that the limiting block 501 is inserted and locked in the limiting groove 401, thus fixing the collection box 4 at the bottom of the fixing block 3, which facilitates the support of the collection box 4 and makes it convenient to collect purified impurities. Furthermore, by pressing the limiting block 501 inward through the limiting groove 401, the limiting block 501 is disengaged from the limiting groove 401. Then, by pulling the collection box 4 downward, the connecting block 5 is disengaged from the collection box 4, which makes it easy to remove the collection box 4 from the fixing block 3 and facilitates the cleaning of the purified impurities in the collection box 4.

[0036] A compression spring 502 is fixedly installed on the inner wall of the groove opened on the outer wall of the connecting block 5, and the other end of the compression spring 502 is fixedly installed on the outer wall of the limiting block 501. The limiting block 501 is pushed outward by the pushing force of the compression spring 502, so that the limiting block 501 is tightly locked in the limiting groove 401, forming a stable connection structure. It is not easy to loosen or fall off when not adjusted, thus improving the stability and reliability of positioning and ensuring the normal operation of the component.

[0037] The inner wall of the inner cavity of the housing 1 is provided with a slot 103, and a side block 201 is fixedly provided on the outer wall of the filter plate 2. The side block 201 is connected and locked in the slot 103. The inner wall of the slot 103 supports the side block 201, which promotes the stability of the filter plate 2.

[0038] The filter plate 2 has a positioning groove 202 on its top, and the outer wall of the fixing block 3 has a groove. The inner wall of the groove on the outer wall of the fixing block 3 is through which a positioning rod 302 is inserted. The bottom of the positioning rod 302 is connected to and inserted into the positioning groove 202. During use, the filter plate 2 is positioned to prevent the filter plate 2 from moving at will and affecting the filtration effect.

[0039] The fixed block 3 has a connecting groove 304 inside, and a push plate 305 is movably inserted into the inner wall of the connecting groove 304. The push plate 305 is fixedly set between the two sets of positioning rods 302. In use, the push plate 305 restricts the movement range of the positioning rods 302 within the connecting groove 304, preventing them from detaching from the fixed block 3 at will. It is also used to connect the two sets of positioning rods 302 together for convenient simultaneous operation.

[0040] A spring strip 306 is fixedly installed on the inner wall of the connecting groove 304, and the other end of the spring strip 306 is fixedly installed on the top of the push plate 305. The push plate 305 is pushed downward by the pushing force of the spring strip 306, so that the downward moving push plate 305 drives the positioning rod 302 to move downward, so that the positioning rod 302 is tightly inserted into the positioning groove 202 under the action of the spring strip 306, forming a stable connection structure. It is not easy to loosen or fall off when not adjusted, thus improving the stability and reliability of positioning and ensuring the normal operation of the component.

[0041] An adjustment block 303 is fixedly installed on the top of the positioning rod 302 for easy hand adjustment by the user.

[0042] A feeding channel 101 is fixedly installed on the top of the box 1, and a discharging channel 102 is fixedly installed on the bottom of the box 1. Epoxy resin enters the box 1 through the feeding channel 101, is purified by the filter plate 2, and then the valve is opened to discharge the purified epoxy resin through the discharging channel 102.

[0043] Specifically, the working principle and operation method of this utility model are as follows:

[0044] During use, epoxy resin enters the housing 1 through the feed channel 101, is purified by the filter plate 2, and then the valve is opened, allowing the purified epoxy resin to be discharged through the discharge channel 102. During use, the user pulls the adjusting block 303 upwards, causing the positioning rod 302 to move upwards and disengage from the positioning groove 202. At this time, by pulling the filter plate 2 outwards, the outer wall of the scraper 301 contacts the surface of the filter plate 2, scraping away impurities from the surface of the filter plate 2. The scraper 301 is positioned outside the housing 1 to prevent scraped impurities from falling into the housing 1 and affecting the purification quality of the epoxy resin. After the impurities on the surface of the filter plate 2 are scraped away by the scraper 301, the filter plate 2 is removed from the housing 1. At this time, the impurities scraped by the scraper 301 fall downwards under gravity into the collection box 4 for easy collection and subsequent processing.

[0045] In use, the user presses the limiting block 501 inward through the limiting groove 401 to disengage the limiting block 501 from the limiting groove 401. Then, by pulling down the collection box 4, the connecting block 5 disengages from the collection box 4, making it easy to remove the collection box 4 from the fixing block 3. This facilitates the cleaning of the purified impurities inside the collection box 4. After cleaning the impurities, the user presses the limiting block 501 inward through the connecting block 5 to retract the limiting block 501 into the connecting block 5. By aligning the top groove of the collection box 4 with the connecting block 5, the user pushes the collection box 4 upward to insert the connecting block 5 into the inner cavity of the collection box 4. When the limiting block 501 is aligned with the limiting groove 401, the user pushes the limiting block 501 outward through the pushing force of the compression spring 502, causing the limiting block 501 to insert and lock into the limiting groove 401. This fixes the collection box 4 at the bottom of the fixing block 3, providing support for the collection box 4 and facilitating the collection of purified impurities.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
