DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0031] As Figures 1-5 shown, a kind of epoxy resin filtering device used in epoxy resin production proposed in this embodiment includes a bottom shell 1, and further includes:

[0032] A support frame 6, fixed to the bottom end of the bottom shell 1, and a discharge pipe 7 is fixed to the bottom end of one side of the bottom shell 1;

[0033] A tank body 2, detachably installed on the top end of the bottom shell 1, and a filter screen 9 is installed between the tank body 2 and the bottom shell 1;

[0034] A sewage discharge structure 8, arranged at the bottom end of the bottom shell 1, and used for cleaning and discharging foreign matters inside the filter screen 9;

[0035] A tank cover 4, detachably installed on the top end of the tank body 2, and a feed pipe 3 is fixed to one side of the top end of the tank cover 4;

[0036] A pressurizing structure 5, arranged at the top end of the tank cover 4. Among them, the pressurizing structure 5 includes a power assembly installed at the top end of the tank cover 4, a sliding rod 511 sliding inside the top end of the tank cover 4, a pressing plate 507 fixed to the bottom end of the sliding rod 511 and slidably connected to the tank body 2, a rotating frame 512 installed inside the bottom end of the pressing plate 507, a rubber baffle 508 rotatably connected to one side of the rotating frame 512, and a torsion spring 510 installed between the rotating frame 512 and the rubber baffle 508.

[0037] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, as a preferred embodiment, on the basis of the above method, further, the power assembly includes a double-output shaft reducer 505 fixed to the top end of the tank cover 4, a drive motor 506 installed at the input end of the double-output shaft reducer 505, a second bevel gear 509 installed at the top output end of the double-output shaft reducer 505, supports 502 fixed to both sides of the top end of the tank cover 4, a cam 503 rotatably connected to one side of the support 502, a connecting piece 504 rotatably connected inside the cam 503 and connected to the slide bar 511, and a first bevel gear 501 installed on one side of the cam 503 and meshed with the second bevel gear 509. Annular equally spaced through holes are formed inside the top end of the pressure plate 507, and the diameter of the rubber baffle 508 is larger than the diameter of the through holes at the top of the pressure plate 507. The first bevel gear 501 passes through the support 502 and is connected to the cam 503. The slide bars 511 are symmetrically distributed on the vertical center line of the pressure plate 507. By starting the drive motor 506 to drive the double-output shaft reducer 505 to operate, the double-output shaft reducer 505 drives the second bevel gear 509 to rotate. Immediately, the rotating second bevel gear 509 drives the cam 503 to operate through the first bevel gear 501. The rotating cam 503 drives the slide bar 511 to move back and forth through the connecting piece 504. When the slide bar 511 moves upward, the pressure plate 507 driven by the slide bar 511 moves upward. At the same time, using the pressure and weight of the epoxy resin at the top of the pressure plate 507 to push the rubber baffle 508 to overcome the torsion of the torsion spring 510, so that the rubber baffle 508 flips around the rotating frame 512, opening the hole at the bottom of the pressure plate 507, and allowing the epoxy resin to enter the bottom of the pressure plate 507. When the slide bar 511 moves downward, the slide bar 511 drives the pressure plate 507 to squeeze the epoxy resin downward. At the same time, the pressure at the top of the pressure plate 507 decreases, and the pressure at the bottom increases, causing the torsion spring 510 to drive the rubber baffle 508 to reset and block the hole at the bottom of the pressure plate 507, so that the pressure plate 507 squeezes the epoxy resin during the downward movement, increasing the pressure of the epoxy resin, so as to facilitate it to pass through the filter screen 9. Through the reciprocating movement of the pressure plate 507, this process can continue continuously.

[0038] As Figure 5As shown, as a preferred embodiment, on the basis of the above method, further, the sewage discharge structure 8 includes a connecting shaft 801 installed at the bottom output end of the double-output shaft reducer 505 and slidably connected to the pressing plate 507, a scraping plate 803 fixed to the outside of the connecting shaft 801, a reinforcing ring 802 fixed inside the scraping plate 803, a spiral blade shaft 806 installed at the bottom end of the connecting shaft 801, a sewage discharge pipe 804 sleeved at the bottom end of the filter screen 9, and a sewage discharge valve 805 installed at the bottom end of the sewage discharge pipe 804. The sewage discharge pipe 804 extends to the outside of the bottom shell 1 and is connected to the sewage discharge valve 805. There are multiple groups of scraping plates 803, and multiple groups of scraping plates 803 are connected by the reinforcing ring 802. When the pressurizing structure 5 is operating, the double-output shaft reducer 505 drives the connecting shaft 801 to rotate, so that the connecting shaft 801 drives the scraping plate 803 to scrape the foreign matters on the surface of the filter screen 9, so that they enter the inside of the sewage discharge pipe 804. At the same time, the connecting shaft 801 drives the spiral blade shaft 806 to rotate, so that the spiral blade shaft 806 pushes the foreign matters to the bottom of the sewage discharge pipe 804 through the spiral blades on the surface, squeezing the foreign matters to reduce the content of epoxy resin in the foreign matters. When the filtering is completed, start the sewage discharge valve 805 to open to discharge the foreign matters inside the sewage discharge pipe 804. The multiple groups of scraping plates 803 are connected and fixed by the reinforcing ring 802, so that the scraping plates 803 are not easy to generate during rotation.

[0039] Specifically, when the epoxy resin filtering device used in the production of epoxy resin is in use: Pour the epoxy resin into the inside of the tank body 2 through the feed pipe 3, so that the epoxy resin contacts the filter screen 9, start the pressurizing structure 5 to pressurize the epoxy resin inside the tank body 2, accelerate the epoxy resin to pass through the filter screen 9, and the epoxy resin during the process is discharged from the device through the discharge pipe 7. While pressurizing the epoxy resin, the sewage discharge structure 8 cleans the impurities filtered inside the filter screen 9. After the filtering is completed, the foreign matters inside the device can be discharged.

[0040] By starting the driving motor 506 to drive the double-output shaft reducer 505 to operate, the double-output shaft reducer 505 drives the second bevel gear 509 to rotate. Immediately afterwards, the rotating second bevel gear 509 drives the cam 503 to operate through the first bevel gear 501. The rotating cam 503 drives the slide bar 511 to move back and forth through the connecting piece 504. When the slide bar 511 moves upward, the pressing plate 507 driven by the slide bar 511 moves upward. At the same time, using the pressure and weight of the epoxy resin on the top of the pressing plate 507 to push the rubber baffle 508 to overcome the torsion of the torsion spring 510, so that the rubber baffle 508 flips around the rotating frame 512, opening the hole at the bottom of the pressing plate 507, allowing the epoxy resin to enter the bottom of the pressing plate 507. When the slide bar 511 moves downward, the slide bar 511 drives the pressing plate 507 to squeeze the epoxy resin downward. At the same time, the pressure on the top of the pressing plate 507 decreases and the pressure on the bottom increases, causing the torsion spring 510 to drive the rubber baffle 508 to reset and block the hole at the bottom of the pressing plate 507, so that the pressing plate 507 squeezes the epoxy resin during the downward movement, increasing the pressure of the epoxy resin, facilitating its passage through the filter screen 9. Through the reciprocating movement of the pressing plate 507, this process can continue continuously;

[0041] When the pressurizing structure 5 is operating, the double-output shaft reducer 505 drives the connecting shaft 801 to rotate, so that the connecting shaft 801 drives the scraper 803 to scrape the foreign matter on the surface of the filter screen 9, making it enter the inside of the sewage pipe 804. At the same time, the connecting shaft 801 drives the spiral blade shaft 806 to rotate, so that the spiral blade shaft 806 pushes the foreign matter to move towards the bottom of the sewage pipe 804 through the spiral blades on the surface, squeezing the foreign matter to reduce the epoxy resin content in the foreign matter. When the filtration is completed, start the sewage discharge valve 805 to open to discharge the foreign matter inside the sewage pipe 804. The multi-group scrapers 803 are connected and fixed through the reinforcement ring 802, so that the scrapers 803 are not easily deformed during rotation.

[0042] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
