Description

Technical Field

[0001] The invention relates to the technical field of epoxy resin production, in particular to equipment and a process for preparing brominated epoxy resin. Background Art

[0002] Brominated epoxy resin is an epoxy resin with bromine elements in its molecular structure and self-extinguishing function, also known as bromine-containing epoxy resin, brominated epoxy resin. Brominated epoxy resin is a milky white or light yellow solid substance. It has excellent chemical and physical properties, can be stable under a wide range of temperature, humidity and pH conditions, and has excellent water resistance, oil resistance, chemical resistance and mechanical properties. In the preparation process of brominated epoxy resin, a bag filter is needed to remove impurities in the solution to make it clean and clear.

[0003] There is a brominated epoxy resin bag filter on the market. In order to prevent impurities from accumulating at the bottom of the filter bag and affecting the filtering speed of the filter bag, a push rod motor is installed under the filter bag. The push rod motor drives the bottom of the filter bag to move up and down through the telescopic movement of the push rod motor, so that the impurities accumulated at the bottom of the filter bag are pushed to the sides of the filter bag. In the process of the push rod motor pushing the bottom of the filter bag up and down, although the impurities at the bottom of the inner side of the filter bag can be pushed to the sides of the filter bag, when the bottom of the filter bag moves down and resets, the impurities pushed to the sides of the filter bag will quickly return to the bottom of the filter bag with the flow of liquid, resulting in poor dredging effect on the bottom of the filter bag. In addition, the clogging of the side wall of the filter bag by impurities will be aggravated by the process of moving the bottom of the filter bag up and down, thereby slowing down the filtering speed of the brominated epoxy resin by the filter bag.

[0030] Working principle: When filtering the brominated epoxy resin, the brominated epoxy resin enters the filter tank 1 through multiple feed pipes 5 and falls on the filter cloth 6. The filter cloth 6 filters the brominated epoxy resin. The filtered brominated epoxy resin is discharged from the filter tank 1 through the discharge pipe 3. Impurities in the brominated epoxy resin will remain on the upper side of the filter cloth 6. In the process of filtering the brominated epoxy resin by the filter cloth 6, the motor 19 drives the outer gear ring 16 and the connecting ring 15 to rotate through the first gear 20. The long pressure rod 21 and the short pressure rod 22 rotate with the connecting ring 15. In the process of supporting the support ring 7 with the elastic support of the support rods 9 in the multiple support assemblies, the support ring 7 and the filter cloth 6 can be driven to swing in a circle. Since the brominated epoxy resin has a certain viscosity, the impurities filtered out by the filter cloth 6 will roll and gather into a ball on the filter cloth 6 during the circular swing of the filter cloth 6. In addition, since the multiple feed pipes 5 disperse the brominated epoxy resin for feeding, it can effectively prevent the impurities from being dispersed on the filter cloth 6 and affecting the filtering speed of the filter cloth 6.

[0031] After the filtration of the brominated epoxy resin is completed and the filtered impurities are cleaned, the personnel rotates to open the top cover 2, then takes out the filter cloth 6 from the inside of the filter tank 1 through the support ring 7, and pours out the impurities filtered by the filter cloth 6.

[0032] After the filtration of the brominated epoxy resin is completed, the personnel rotates the knob 36 to move the pressure plate 32 downward under the drive of the compression elastic force of the second spring 35. During the downward movement, the pressure plate 32 can drive the multiple dome-shaped cones 33 to resist the rubber block 29, so that when the motor 19 drives the hollow shaft 31 to rotate through the first gear 20 and the third gear 30, the hollow shaft 31 can drive the connecting shaft 28 and the second gear 27 to rotate through the multiple dome-shaped cones 33 and the rubber block 29. During the rotation, the second gear 27 drives the inner gear ring 24 and the two scrapers 26 to rotate. During the rotation, the two scrapers 26 can scrape off the brominated epoxy resin attached to the inner wall of the filter tank 1, thereby preventing the brominated epoxy resin from being wasted.

[0033] Before filtering the brominated epoxy resin, the personnel rotates the knob 36 to a vertical position. During the rotation, the knob 36 drives the pressure plate 32 to move upward through the spline shaft 34, so that the multiple dome-shaped cones 33 are separated from the rubber block 29. At this time, when the motor 19 drives the first gear 20 to rotate, the hollow shaft 31 drives the pressure plate 32 and the multiple dome-shaped cones 33 to rotate idly, that is, when filtering the brominated epoxy resin, the two scrapers 26 are in a stationary state inside the filter tank 1, which can avoid the scraper 26 from contacting and rubbing with the inner wall of the filter tank 1 for a long time, reduce the wear of the scraper 26, and extend the service life of the scraper 26.

[0034] When the rubber block 29 needs to be replaced, the operator rotates the threaded sleeve 40 to disengage it from the connecting seat 39 , and then removes the connecting seat 39 from the rectangular pin 38 .

A process for preparing a brominated epoxy resin according to claim 8, characterized in that: The following steps are involved: S1: separation stage, the brominated epoxy resin enters the filter tank (1) through a plurality of feed pipes (5), and the filter cloth (6) inside the filter tank (1) filters the brominated epoxy resin; S2: swinging stage, the motor (19) drives the connecting ring (15) to rotate via the first gear (20) and the outer gear ring (16), and the long pressure rod (21) and the short pressure rod (22) drive the filter cloth (6) to swing in a circle via the support ring (7) as the connecting ring (15) rotates, so that impurities filtered out by the filter cloth (6) gather together in the filter cloth (6); S3: in the adjustment stage, the knob (36) is turned to move the pressure plate (32) downward under the driving force of the compression force of the second spring (35), and the pressure plate (32) drives the plurality of dome-shaped cones (33) to press against the rubber block (29) during the downward movement; S4: scraping stage, the motor (19) drives the hollow shaft (31), i.e., the pressure plate (32), to rotate through the first gear (20) and the third gear (30), the pressure plate (32) drives the rubber block (29) and the second gear (27) to rotate through a plurality of dome-shaped cones (33), the second gear (27) drives the inner gear ring (24) and the two scraping strips (26) to rotate, and the scraping strips (26) scrape off the brominated epoxy resin attached to the inner wall of the filter tank (1) during the process of rotating in contact with the inner wall of the filter tank (1).
