Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to an epoxy resin filtration device. Background Technology

[0002] 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 particulate matter and iron filings.

[0003] Chinese utility model patent CN216320343U discloses an epoxy resin filtration device that can divide the conveyed material through a diversion structure and filter it with the help of a filtration structure. It can also adjust the flow rate of the diversion and the liquid space of the centralized conveying to accelerate the filtration speed and prevent clogging. Then, it achieves a dual filtration effect through a first filter screen and a second filter screen, and the whole device is easy to disassemble for replacement or cleaning.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: During the use of the device, it is inconvenient to stir the epoxy resin, and the material on the inner wall also needs to be scraped off to ensure the discharge effect of the epoxy resin filtration. During the filtration process, the epoxy resin may clog the filter holes, thereby affecting the overall filtration effect of the device. It is necessary to shake off the epoxy resin that is clogging the filter holes to ensure the overall filtration efficiency of the device. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an epoxy resin filtration device.

[0006] This utility model is achieved by the following technical solution: an epoxy resin filtration device, including a box, a collection box installed at the bottom of the inner wall of the box, and a lifting component installed at the top of the box.

[0007] The lifting assembly includes two support plates. A rotating rod is rotatably connected to the back of the front support plate. A drive motor is fixedly connected to one end of the rotating rod. A small bearing is installed on the outside of the rotating rod and on the surface of the back support plate. A cam is sleeved on the outside of the rotating rod. A U-shaped frame abuts against the surface of the cam. Two lifting rods are fixedly connected to the bottom of the U-shaped frame. A screening assembly is fixedly connected to the bottom end of the lifting rods.

[0008] The screening assembly includes a mounting box and a screening box. The bottom of the mounting box is fixedly connected to the top of the screening box, and the top of the mounting box is fixedly connected to the bottom of the lifting rod. A support rod is installed inside the mounting box, and connecting gears are fixedly connected to both ends of the support rod. Fixed toothed plates are meshed with the surfaces of the connecting gears, and the surfaces of the fixed toothed plates are fixedly connected to the inner wall of the box. A helical gear A is sleeved on the outside of the support rod, and a helical gear B is meshed with the surface of helical gear A. The bottom end of the intermediate shaft of helical gear B is rotatably connected to the bottom of the inner wall of the screening box. Three connecting rings are sleeved on the outside of the intermediate shaft of helical gear B. A hard brush plate is fixedly connected to the surface of the lower connecting ring, and two connecting rods are fixedly connected to the surfaces of the remaining connecting rings. A scraper is fixedly connected to one end of each connecting rod.

[0009] As a further improvement to the above solution, a mounting block is fixedly connected to the bottom of the drive motor, and the front of the mounting block is fixedly connected to the back of the back support plate, ensuring the normal operation of the drive motor.

[0010] As a further improvement to the above solution, two openings are provided on the top of the box, and the lifting rod is slidably disposed inside the openings to ensure the normal movement of the lifting rod.

[0011] As a further improvement to the above solution, the bottom of the screening box is provided with filter holes at equal intervals to facilitate filtration.

[0012] As a further improvement to the above solution, the front of the collection box is connected to a discharge pipe, and a valve is installed on the outside of the discharge pipe to facilitate the discharge operation.

[0013] As a further improvement to the above solution, two rotary bearings are installed on the outer side of the support rod. The rotary bearings are installed on one side of the mounting box to ensure the normal rotation of the support rod.

[0014] As a further improvement to the above solution, the top of the screening box is connected to a telescopic feed pipe, and the outer side of the telescopic feed pipe is connected through the top of the box body to facilitate the addition of materials into the screening box.

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

[0016] 1. This utility model, by setting up a lifting component and starting the drive motor, causes the rotating rod to rotate. The rotating rod drives the cam to rotate, causing the cam to continuously strike the return frame, causing the return frame to move up and down in the vertical direction. This, in turn, causes the lifting rod to move up and down with the mounting box in the vertical direction, causing the mounting box to vibrate back and forth. Epoxy resin is then introduced into the screening box through the telescopic feed pipe. Under the up and down vibration of the mounting box, the epoxy resin falls into the collection box through the filter holes, reducing the possibility of epoxy resin clogging the filter holes and ensuring the overall filtration efficiency of the device.

[0017] 2. This utility model, by setting up a screening component, ensures that during the lifting and lowering movement of the lifting rod carrying the mounting box, the surface of the connecting gear is subjected to the action of the fixed tooth plate, causing the connecting gear to reciprocate. This reciprocates the support rod, causing helical gear A to rotate with helical gear B, which in turn causes the intermediate shaft of helical gear B to reciprocate with the connecting ring. This causes the connecting rod to scrape off the epoxy resin adhering to the inner wall of the screening box with the scraper. At the same time, the hard brush plate sweeps the bottom of the inner wall of the screening box, brushing off the epoxy resin in the filter holes and brushing large particles away from the filter holes. This reduces the situation of epoxy resin adhering to the inner wall of the screening box and large particles clogging the filter holes, ensuring the discharge effect of the device.

The front of the mounting block is fixedly connected to the back of the back support plate 3 to ensure the normal operation of the drive motor. The back of the front support plate 3 is rotatably connected to a rotating rod 4. One end of the rotating rod 4 is fixedly connected to the drive motor. A small bearing is installed on the outside of the rotating rod 4. The small bearing is installed on the surface of the back support plate 3. A cam 5 is sleeved on the outside of the rotating rod 4. The surface of the cam 5 abuts against a U-shaped frame 6. Two lifting rods 7 are fixedly connected to the bottom of the U-shaped frame 6. Two openings are opened on the top of the box 1. The lifting rods 7 are slidably set inside the openings to ensure the normal movement of the lifting rods 7. A screening assembly is fixedly connected to the bottom of the lifting rods 7.

[0027] The screening assembly is used to filter epoxy resin. The assembly includes a mounting box 8 and a screening box 9. The bottom of the screening box 9 has evenly spaced filter holes for easy filtration. The bottom of the mounting box 8 is fixedly connected to the top of the screening box 9. A telescopic feed pipe is connected to the top of the screening box 9, and its outer side extends through the top of the housing 1, facilitating the addition of material into the screening box 9. The top of the mounting box 8 is fixedly connected to the bottom of the lifting rod 7. A support rod 10 is installed inside the mounting box 8, and two rotary bearings are installed on the outer side of the support rod 10. These bearings are mounted on one side of the mounting box 8 to ensure the normal rotation of the support rod 10. Both ends of the rod 10 are fixedly connected to connecting gears 11. The surfaces of the connecting gears 11 are meshed with fixed tooth plates 12. The surfaces of the fixed tooth plates 12 are fixedly connected to the inner wall of the box 1.

[0028] The implementation principle of the epoxy resin filtration device in this application embodiment is as follows: The drive motor is started, causing the rotating rod 4 to rotate. The rotating rod 4 drives the cam 5 to rotate, causing the cam 5 to continuously strike the retaining frame 6, causing the retaining frame 6 to move vertically up and down. This causes the lifting rod 7 to move vertically up and down, causing the mounting box 8 to vibrate back and forth. Epoxy resin is then introduced into the screening box 9 through the telescopic feed pipe. Under the up-and-down vibration of the mounting box 8, the epoxy resin falls through the filter holes into the collection box 2, reducing the possibility of epoxy resin clogging the filter holes and ensuring the overall filtration efficiency of the device.

[0029] During the lifting and lowering movement of the lifting rod 7 carrying the mounting box 8, the surface of the connecting gear 11 is subjected to the action of the fixed tooth plate 12, causing the connecting gear 11 to reciprocate, causing the support rod 10 to reciprocate, causing the helical gear A13 to rotate with the helical gear B14, and then causing the intermediate shaft of the helical gear B14 to reciprocate with the connecting ring 15, causing the connecting rod 17 to scrape off the epoxy resin adhering to the inner wall of the screening box 9 with the scraper 18. At the same time, the hard brush plate 16 brushes the bottom of the inner wall of the screening box 9, brushing off the epoxy resin in the filter holes and brushing large particles away from the filter holes, reducing the situation of epoxy resin adhering to the inner wall of the screening box 9 and large particles clogging the filter holes, thus ensuring the discharge effect of the device.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
