Description

Technical Field

[0001] This utility model belongs to the field of ion exchange resin production technology, and in particular relates to a pollution-resistant enhanced strong base anion exchange resin preparation equipment. Background Technology

[0002] In the production of antifouling-enhanced strong-base anion exchange resin, firstly, cross-linked polystyrene white spheres are prepared through a suspension copolymerization reaction of styrene and divinylbenzene, serving as the resin matrix. Subsequently, a chloromethylation reaction is carried out using chloromethyl ether and a catalyst to introduce chloromethyl groups onto the benzene ring. Next, amination treatment with trimethylamine solution converts the chloromethyl groups into quaternary ammonium groups, forming a strong-base anion exchange resin. To enhance antifouling performance, various modification methods are typically employed, such as surface coating with hydrophilic polymers (e.g., polyvinyl alcohol) to form a protective layer, designing a cross-linking degree gradient structure to improve outer layer density, and introducing weakly basic or amphoteric groups to improve selectivity. However, the preparation of antifouling-enhanced strong-base anion exchange resin still suffers from the following drawbacks:

[0003] In the preparation process of anti-fouling enhanced strong base anion exchange resin, the exchange resin is directly fed into the coating equipment for coating operations. During the coating process, the resin particles need to be fed into the coating equipment, output after coating, and then re-input. The continuous coating operation in the coating equipment is not convenient.

[0004] Secondly, in the production of anti-pollution reinforced strong base anion exchange resin, after directly coating it with a polyvinyl alcohol aqueous solution, the coating process requires applying an appropriate amount of polyvinyl alcohol, continuous stirring and mixing after spraying, and multiple spraying steps, which is not convenient. Utility Model Content

[0005] The purpose of this invention is to provide a device for preparing anti-pollution enhanced strong base anion exchange resin. By setting up a conveying chamber, a feed pipe, a drive assembly, a support shell, and a support frame, it solves the problems of insufficient continuity of modification coating and inconvenience of multi-step spraying in the preparation of anti-pollution enhanced strong base anion exchange resin.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a pollution-resistant enhanced strong basic anion exchange resin preparation device, comprising a conveying chamber, a feed pipe, a drive assembly, a support shell, and a support frame. Spiral blades are fixed to the inner wall of the conveying chamber. A feed pipe is movably connected to one end of the conveying chamber. A support shell is located at the end of the conveying chamber away from the feed pipe. A support frame is fixed at the end of the support shell away from the conveying chamber. A feed pipe is fixedly connected to the support frame, extending into the conveying chamber. Nozzles are fixedly connected at equal intervals to the lower periphery of the feed pipe within the conveying chamber. The drive assembly is symmetrically arranged on the lower periphery of the conveying chamber. During operation, resin particles are conveyed by the spiral blades in the conveying chamber and by the feed pipe. The drive assembly drives the conveying chamber to rotate during operation. The support shell receives the resin particles output from the conveying chamber, and the support frame fixes the feed pipe within it.

[0008] Furthermore, a support ring is fixed to the periphery of the conveying chamber near the edge of the supporting shell, and an annular groove is fixed to the periphery of the supporting shell near the edge of the conveying chamber. The support ring is movably connected in the annular groove, and the conveying chamber is movably connected to the annular groove through the support ring, thereby restricting and supporting the conveying chamber.

[0009] Furthermore, two limiting rings are fixed around the feed pipe. The two limiting rings are respectively set on the inner and outer sides of the conveying chamber and respectively contact the inner wall and surface of the conveying chamber. The feed pipe is restricted in its position relative to the conveying chamber by the limiting rings.

[0010] Furthermore, the drive assembly includes a support plate, a drive shaft, and support rollers. The upper part of the two support plates, which are close to each other, is rotatably connected to the drive shaft. Support rollers are fixed at both ends of the drive shaft. The drive assembly supports the drive shaft through the support plates and supports the conveyor bin on the support plates through the support rollers.

[0011] Furthermore, the drive assembly also includes a drive motor. The drive motor is fixed on the upper part of a support plate of the same drive assembly on the side away from the support roller. The output shaft of the drive motor passes through the support plate and is fixed to the transmission shaft. The drive assembly drives the output shaft to rotate through the drive motor, and drives the support roller to rotate during the rotation of the output shaft.

[0012] Furthermore, an output pipe is fixedly connected to the lower periphery of the support shell, and the material conveying pipe passes through the inside of the support shell, through which the support shell outputs the resin particles that have entered it.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of insufficient continuity in the modification coating process during the preparation of anti-fouling enhanced strong base anion exchange resin by setting up a conveying chamber, a feed pipe, a drive assembly, and a support shell. The two drive assemblies, including drive motors, rotate the transmission shaft. During the rotation of the transmission shaft, the conveying chamber rotates, and resin particles are conveyed through the feed pipe to the end of the conveying chamber furthest from the support shell. The rotation of the conveying chamber drives the spiral blades to rotate, causing the resin particles to be spirally conveyed and transported to the support shell, and then output through the output pipe. This allows for continuous modification coating during the preparation of anti-fouling enhanced strong base anion exchange resin, resulting in better coating continuity.

[0015] This invention solves the problem of inconvenience in multi-step spraying of anti-pollution enhanced strong base anion exchange resin coating modified coatings by setting up a conveying chamber, a drive component, a support shell, and a support frame. During the rotation of the conveying chamber, polyvinyl alcohol solution is transported to the nozzle through the conveying pipe, and sprayed onto the resin particles between the spiral blades in the conveying chamber. This ensures that the surface of the resin particles is fully coated with polyvinyl alcohol aqueous solution, making the multi-step spraying of anti-pollution enhanced strong base anion exchange resin coating modified coatings more convenient.

A spiral blade 101 is fixed on the inner wall of the conveying chamber 1. The conveying chamber 1 conveys the resin particles to be processed. During the rotation of the conveying chamber 1, the spiral blade 101 drives the resin particles to move and roll. The feed pipe 2 is movably connected to one end of the conveying chamber 1. The end of the feed pipe 2 away from the conveying chamber 1 is fixedly connected to the equipment for inputting resin particles, conveying the resin particles into the conveying chamber 1. A support shell 4 is provided at the end of the conveying chamber 1 away from the feed pipe 2, supporting one end of the conveying chamber 1. A support frame is fixed at the end of the support shell 4 away from the conveying chamber 1. 5. The support frame 5 supports the conveying chamber 1 above the working plane. A conveying pipe 501 is fixedly installed inside the support frame 5. The conveying pipe 501 extends into the conveying chamber 1. The end of the conveying pipe 501 away from the support shell 4 is connected to the output end of the equipment for conveying polyvinyl alcohol aqueous solution, so as to convey the polyvinyl alcohol aqueous solution to the nozzle 502. The lower periphery of the conveying pipe 501 in the conveying chamber 1 is fixedly connected to the nozzle 502 at equal intervals. When the nozzle 502 is working, it sprays the polyvinyl alcohol aqueous solution conveyed by the conveying pipe 501 into the conveying chamber 1. The polyvinyl alcohol solution is sprayed in stages by the nozzle 502, with a 30-second interval between each stage to promote uniform adsorption. The lower periphery of the conveying chamber 1 is symmetrically provided with the drive assembly 3, which drives the conveying chamber 1 to rotate.

[0027] Specifically, a support ring 102 is fixed on the periphery of the conveying chamber 1 near the edge of the support shell 4, and an annular groove 401 is fixed on the periphery of the support shell 4 near the edge of the conveying chamber 1. The support ring 102 is movably connected in the annular groove 401. When the conveying chamber 1 is working, the resin of the sprayed polyvinyl alcohol aqueous solution conveyed in the conveying chamber 1 is conveyed to the support shell 4 through the annular groove 401 on the support shell 4 via the movable connection of the support ring 102.

[0028] Furthermore, two limiting rings 201 are fixed around the feed pipe 2. The two limiting rings 201 are respectively set on the inner and outer sides of the conveying chamber 1 and respectively contact the inner wall and surface of the conveying chamber 1. The feed pipe 2 is restricted in position on the conveying chamber 1 by the limiting rings 201.

[0029] Furthermore, the drive assembly 3 includes a support plate 301, a drive shaft 302, and a support roller 303. The upper part of the two support plates 301, which are close to each other, is rotatably connected to the drive shaft 302. The two ends of the drive shaft 302 are fixed with the support roller 303. The support plate 301 supports the drive shaft 302 on it, and the support roller 303 on the drive shaft 302 supports the conveying chamber 1 above the working plane through the support plate 301.

[0030] Furthermore, the drive assembly 3 also includes a drive motor 304. The drive motor 304 is fixed on the upper part of a support plate 301 on the side away from the support roller 303. The output shaft of the drive motor 304 passes through the support plate 301 and is fixed to the transmission shaft 302. The drive motor 304 drives the transmission shaft 302 to rotate, which in turn drives the support roller 303 to rotate. After the support roller 303 rotates, it drives the conveying bin 1 to rotate.

[0031] The operation process of this embodiment is as follows: During operation, the two drive components 3 include drive motors 304, which drive the transmission shaft 302 to rotate. During the rotation of the transmission shaft 302, the conveying chamber 1 is driven to rotate. During the rotation of the conveying chamber 1, the resin particles are conveyed to the end of the conveying chamber 1 away from the support shell 4 through the feed pipe 2. The rotation of the conveying chamber 1 drives the spiral blades 101 to rotate, so that the resin particles are spirally conveyed and conveyed into the support shell 4, and output through the output pipe 402. Specific Implementation Example 2

The bottom end of the output pipe 402 on the lower periphery of the support shell 4 is connected to the equipment input pipe for drying resin particles. The conveying pipe 501 passes through the support shell 4, so that the conveying pipe 501 can convey the polyvinyl alcohol solution nozzle 502 to the conveying chamber 1.

[0033] The operation process of this embodiment is as follows: During operation, when the conveying chamber 1 rotates, the polyvinyl alcohol solution is conveyed to the nozzle 502 through the conveying pipe 501, and sprayed out by the nozzle 502 onto the resin particles between the spiral blades 101 in the conveying chamber 1, so that the surface of the resin particles is fully coated with the polyvinyl alcohol aqueous solution.
