Description

Technical Field

[0001] This utility model relates to the field of epoxy resin technology, specifically to an epoxy resin filtration device used in epoxy resin production. Background Technology

[0002] Epoxy resin is a high molecular polymer, which refers to a class of polymers containing two or more epoxy groups in their molecules. It is a thermosetting polymer synthetic material.

[0003] During the production of epoxy resin, as the polymerization reaction proceeds, a certain amount of other raw materials are added to the reaction system. After the reaction is completed, a large number of impurities remain in the system, including liquid impurities and solid impurities. Liquid impurities can be removed by adding specific substances to cause a chemical reaction or recovered in subsequent processes. Solid impurities include some particulate matter.

[0004] Chinese patent provides an epoxy resin filtration device, publication number CN221771690U, which includes a main shell. Bases are welded to both sides of the bottom of the main shell. A threaded pipe is welded to the center of the bottom of the main shell. A first outlet is fixedly connected to one side of the threaded pipe. A first rotating plate is movably connected to the bottom of the first outlet. A threaded block is threadedly connected inside the threaded pipe. A second rotating plate is fixedly connected to the bottom of the threaded block. A motor is fixedly connected to the bottom of the second rotating plate. A support block is tightly fitted to the bottom of the motor. A filter screen is fixedly connected inside the main shell. A universal joint is fixedly connected to the top of the main shell. An inlet is movably connected to the top of the universal joint.

[0005] Although the device is equipped with a filter screen for filtration, epoxy resin is a thermosetting polymer synthetic material, so its fluidity is very low compared to other fluids. In order to achieve the filtration effect, the filter screen has very small pores. This results in a long filtration time when relying on gravity, leading to low filtration efficiency.

[0006] Therefore, there is a need to provide an epoxy resin filtration device for epoxy resin production. Utility Model Content

[0007] The purpose of this invention is to provide an epoxy resin filtration device for epoxy resin production, so as to solve the problem mentioned in the background art that the filtration time required by gravity is very long, resulting in low filtration efficiency.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an epoxy resin filtration device for epoxy resin production, comprising a storage tank and a top cover, wherein an intermittent pressing mechanism is fixedly installed on the top surface of the top cover, and a filtration mechanism is provided inside the storage tank; the intermittent pressing mechanism comprises a fixed block and a sleeve, wherein the bottom surface of the fixed block is fixedly connected to the top surface of the top cover, a servo motor is fixedly installed on the top surface of the fixed block, an eccentric wheel is fixedly installed on the end surface of the servo motor transmission rod, a push rod is slidably arranged on the inner wall of the sleeve, an mounting component is fixedly installed on the top surface of the push rod, a top block is fixedly installed on the top surface of the mounting component, the top surface of the top block abuts against the side of the eccentric wheel, a return spring is fixedly installed on the top surface of the top cover, the top surface of the return spring is fixedly connected to the bottom surface of the mounting component, a limit block is fixedly installed on the side of the mounting component, the limit block has a through hole extending vertically, a guide rod is slidably installed on the inner wall of the through hole, and the bottom surface of the guide rod is fixedly connected to the top surface of the top cover.

[0009] Preferably, a pressure plate is fixedly installed on the bottom end face of the push rod, and a rubber ring is fixedly installed on the bottom end face of the pressure plate.

[0010] Preferably, a protective shell is fixedly installed on the top surface of the upper cover, and heat dissipation holes are fixedly opened on the side of the protective shell. The bottom surface of the upper cover is fixedly connected to the top surface of the storage tank, and the lower part of the storage tank is contracted inward.

[0011] Preferably, the filtration mechanism includes a mounting frame, two grooves are fixedly formed on the side of the storage tank, a sealing ring is provided on the inner wall of the groove, the mounting frame is snapped onto the inner wall of the groove, a filter screen is fixedly installed on the inner wall of the mounting frame, a handle is fixedly installed on the side of the mounting frame, and a second filter component is snapped onto the inner wall of the groove.

[0012] Preferably, a funnel is fixedly installed on the bottom end face of the storage tank, a discharge pipe is fixedly installed on the bottom end face of the funnel, and a valve is provided inside the discharge pipe.

[0013] Preferably, a through hole is fixedly opened on the top surface of the upper cover, a feeding port is fixedly installed on the inner wall of the through hole, and a partition is snapped onto the inner wall of the feeding port.

[0014] Preferably, a side plate is fixedly installed on the side of the storage tank, a support leg is fixedly installed on the bottom surface of the side plate, and an anti-slip pad is fixedly installed on the bottom surface of the support leg.

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

[0016] 1) In the epoxy resin production process, the epoxy resin filtration device first activates the servo motor, which drives the eccentric wheel to rotate and push the top block and mounting component downwards. As the mounting component moves downwards, it compresses the return spring, causing the spring to contract and accumulate elastic potential energy. At this time, the lower pressure plate presses the epoxy resin into the filtration process. As the servo motor rotates, it drives the eccentric wheel to rotate. The section of the eccentric wheel near the servo motor transmission rod contacts the top block, at which point the return spring unfolds, pushing the mounting component upwards and causing the push rod and lower pressure plate to rise. The epoxy resin inside the storage tank flows down to the lower pressure plate, performing the filtration operation. Repeating the above reciprocating motion of the lower pressure plate completes the process of pressing down and replenishing epoxy resin, effectively improving the speed of epoxy resin filtration, filtration efficiency, and practicality.

[0017] 2) In this epoxy resin production process, the epoxy resin filtration device first opens the partition, pours the epoxy resin to be filtered into the storage tank, further opens the valve, and then starts the intermittent pressing mechanism to force the epoxy resin into the filtration mechanism. The epoxy resin first passes through the filter screen, and then through the second filter component for two filtrations. This ensures that the epoxy resin is filtered to prevent solid particles from mixing with the epoxy resin and affecting subsequent use. After filtering out the solid particles inside the epoxy resin, it is discharged from the storage tank through the discharge pipe. When the filter screen becomes clogged due to long-term use, it can be replaced by pulling the installation frame by the handle. After replacement, it can be reinstalled for filtration operations. The installation is simple, quick, and saves time and effort. Attached Figure Description

[0025] Example 1

[0026] Combination Figures 1-5 An epoxy resin filtration device for epoxy resin production includes a storage tank 1 and a top cover 2. An intermittent pressing mechanism 6 is fixedly installed on the top surface of the top cover 2. A filtration mechanism 7 is installed inside the storage tank 1. The intermittent pressing mechanism 6 includes a fixing block 601 and a sleeve 604. The bottom surface of the fixing block 601 is fixedly connected to the top surface of the top cover 2. A servo motor 602 is fixedly installed on the top surface of the fixing block 601. An eccentric wheel 603 is fixedly installed on the end face of the transmission rod of the servo motor 602. A push rod 608 is slidably arranged on the inner wall of the sleeve 604. An installation part 605 is fixedly installed on the top surface of the push rod 608. A top block 606 is fixedly installed on the top surface of component 605. The top surface of the top block 606 abuts against the side of the eccentric wheel 603. A return spring 607 is fixedly installed on the top surface of the upper cover 2. The top surface of the return spring 607 is fixedly connected to the bottom surface of the mounting component 605. A limit block 611 is fixedly installed on the side of the mounting component 605. The limit block 611 has a through hole extending through the top and bottom. A guide rod 612 is slidably installed on the inner wall of the through hole. The bottom surface of the guide rod 612 is fixedly connected to the top surface of the upper cover 2. A lower pressure plate 609 is fixedly installed on the bottom surface of the push rod 608. A rubber ring 610 is fixedly installed on the bottom surface of the lower pressure plate 609.

[0027] Specifically, in use, firstly, the servo motor 602 is turned on, driving the eccentric wheel 603 to rotate. The eccentric wheel 603 then pushes the top block 606 downwards, causing the mounting part 605 to move downwards. Simultaneously, the downward movement is guided and limited by the limit block 611 and the guide rod 612, which in turn pushes the push rod 608 to slide on the inner wall of the sleeve 604. When the mounting part 605 moves downwards, it compresses the return spring 607. The return spring 607 contracts, accumulating elastic potential energy. At this time, the lower pressure plate 609 presses the epoxy resin into the filtration process. As the servo motor 602 rotates, it drives the eccentric wheel 603 to rotate. The section of the eccentric wheel 603 near the transmission rod of the servo motor 602 contacts the top block 606. At this time, the reset spring 607 unfolds, pushing the mounting part 605 upward, and driving the push rod 608 and the lower pressure plate 609 to rise. The epoxy resin inside the storage tank 1 flows down to the lower pressure plate 609 to filter the epoxy resin. Repeating the above reciprocating motion of the lower pressure plate 609 can complete the process of pressing down the epoxy resin and replenishing the epoxy resin, thereby improving the filtration speed.

An anti-slip pad 5 is fixedly installed on the bottom end face of the support leg 4.

[0030] Specifically, in use, first open the partition 9 and pour the epoxy resin to be filtered into the storage tank 1. Then, open the valve 707 and start the intermittent pressing mechanism 6 to press the epoxy resin into the filter mechanism 7. The epoxy resin first passes through the filter screen 702 and then through the second filter component 704 for two filtrations. After filtering out the solid particles inside the epoxy resin, it is discharged from the storage tank 1 through the discharge pipe 706. When the filter screen 702 becomes clogged after long-term use, the filter screen 702 can be replaced by pulling the installation frame 701 with the handle 703. After replacement, it can be reinstalled for filtration. The installation is simple and quick, saving time and effort.
