Description

Technical Field

[0001] This utility model relates to the field of brominated epoxy resin technology, specifically to a filtration and purification device for brominated epoxy resin. Background Technology

[0002] Brominated epoxy resin is an epoxy resin containing bromine. It has self-extinguishing and heat resistance properties. The main types include brominated bisphenol A, phenolic, and dibromopentaerythritol. The molecular formula of brominated epoxy resin is C36H32Br8O6. It has a low melting point and viscosity, is easy to process and apply. It is resistant to most solvents and chemicals, exhibiting good corrosion resistance. It is widely used in the construction, aerospace, shipbuilding, and electronics industries to prepare flame-retardant composite materials, electronic components, and circuit boards. It also has applications in marine engineering and petrochemical fields.

[0003] In the current production process of brominated epoxy resin, a filtration device is required to remove impurities and unreacted substances from the resin for purification. After multiple filtrations, the filter needs to be cleaned to prevent clogging and reduced filtration efficiency. Currently, cleaning the filter usually requires removing it from the device. However, since the filter is often located inside the equipment, removing it requires workers to reach inside the filter, which is time-consuming, cumbersome, and affects the usability of the filtration system.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a new technical solution: a filtration and purification device for brominated epoxy resin, including a filter box 1, an upper cover 2 on the upper surface of the filter box 1, a feed pipe 3 fixedly installed on the upper surface of the upper cover 2, the lower end of the feed pipe 3 being open, the feed pipe 3 communicating with the interior of the filter box 1, and mounting plates 4 fixedly installed on both the left and right surfaces of the filter box 1.

[0024] The auxiliary mechanism is located inside the filter box 1. It includes two hydraulic telescopic rods 5, an annular mounting plate 6, and two scrapers 7. The two hydraulic telescopic rods 5 are fixedly mounted on the upper surfaces of the two mounting plates 4, and their telescopic ends are fixedly connected to the upper cover 2. Two connecting plates 8 are fixedly mounted on the lower surface of the upper cover 2, both located inside the filter box 1. The two connecting plates 8 slide in contact with the left and right inner walls of the filter box 1. The annular mounting plate 6 is fixedly mounted at the lower ends of the two connecting plates 8. The two scrapers 7 are fixedly mounted at the front and rear ends of the upper surface of the annular mounting plate 6, and slide in contact with the inner wall of the filter box 1. A filter screen 9 is slidably mounted on the inner wall of the annular mounting plate 6.

[0025] Furthermore, the auxiliary mechanism also includes an annular base plate 10, which is fixedly connected to the lower end of the inner wall of the annular mounting plate 6, and the filter screen 9 is located at the upper end of the annular base plate 10.

[0026] Furthermore, by using two hydraulic telescopic rods 5 to move the annular mounting plate 6 upward, the two scrapers 7 and the filter screen 9 on the annular mounting plate 6 move upward. The two scrapers 7 further scrape and clean the inner wall of the filter box 1, causing it to fall onto the filter screen 9, and then bring the filter screen 9 to the top of the filter box 1, making it easier to disassemble and clean the filter screen 9, reducing the difficulty of cleaning the device and improving the work efficiency of the staff.

[0027] Furthermore, T-shaped grooves 11 are provided on the distant surfaces of the two connecting plates 8, and the proximal ends of the two T-shaped grooves 11 extend to the proximal surfaces of the two connecting plates 8. T-shaped plates 12 are slidably installed inside the two T-shaped grooves 11, and the two T-shaped plates 12 are in sliding contact with the upper surface of the filter screen 9.

[0028] Furthermore, semi-circular grooves 13 are provided on the upper and lower surfaces of both T-shaped plates 12.

[0029] Furthermore, a rectangular groove 14 is provided on the rear surface of the filter box 1, and the upper surface of the rectangular groove 14 is open. A limiting plate 15 is fixedly installed on the lower surface of the cover 2 corresponding to the position of the rectangular groove 14.

[0030] Furthermore, a baffle 16 is slidably inserted into the inside of the rectangular groove 14, and a limiting groove 17 is formed on the baffle 16 at the position corresponding to the limiting plate 15. The limiting plate 15 and the limiting groove 17 are slidably inserted into each other.

[0031] Furthermore, when using this device to filter and purify brominated epoxy resin, the brominated epoxy resin to be filtered and purified is added into the filter box 1 through the feed pipe 3. The brominated epoxy resin is filtered through the filter screen 9. When the filter screen 9 needs to be cleaned, first activate the two hydraulic telescopic rods 5, causing the two hydraulic telescopic rods 5 to move the upper cover 2, which is fixedly connected to its telescopic end, upward a certain distance. This causes the limiting plate 15, which is fixedly connected to the upper cover 2, to move upward and leave the interior of the limiting groove 17. At this time, the baffle 16 can be pulled out from the interior of the rectangular groove 14, and the interior of the filter box 1 can be rinsed with water through the rectangular groove 14. After rinsing, the two hydraulic telescopic rods 5 can be activated again, causing the two hydraulic telescopic rods 5 to move the upper cover 2 upward. The upward movement of the upper cover 2 causes the two fixedly connected... The plate 8 moves upward, and the two connecting plates 8 move upward, causing the annular mounting plate 6 fixedly connected to it to move upward. The annular mounting plate 6 causes the annular base plate 10 and the two scrapers 7 fixedly connected to it to move upward, thereby causing the filter screen 9 above the annular base plate 10 to move upward. The two scrapers 7 move upward and scrape the inner wall of the filter box 1, scraping the residual brominated epoxy resin on the inner wall of the filter box 1 onto the filter screen 9. When the two hydraulic telescopic rods 5 move the upper cover 2 and the filter screen 9 to the top of the filter box 1, the two T-shaped plates 12 can be pushed to move them away from each other. The two T-shaped plates 12 can leave the inside of the two T-shaped grooves 11 and leave the upper surface of the filter screen 9. At this time, the filter screen 9 can be pushed upward from the inside of the annular mounting plate 6 to remove the filter screen 9 for cleaning.
