A reaction vessel for producing high-temperature resistant polyester powder coatings

Abstract

This utility model discloses a reactor for producing high-temperature resistant polyester powder coatings, including a reactor body. A feed hopper is connected to the upper surface of the reactor body. A heat insulation layer, made of nano-anti-corrosion and heat-insulating coating, is connected to the inner wall of the reactor body. A first motor is connected to the upper surface of the reactor body, and a first rotating column is connected to the output end of the first motor. A first bearing is embedded in the inner top wall of the reactor body. This device uses the first motor to drive the first rotating column to rotate, causing an adjusting rod to drive a stirring rod to rotate on the outer surface of the first rotating column, thereby stirring the material. A second motor is then activated to drive the second rotating column to rotate, causing a first spiral blade to rotate on the outer surface of the second rotating column, thus stirring the material. This prevents the material from agglomerating due to excessive temperature. The first spiral blade and the stirring rod work together to ensure more thorough and uniform stirring, improving stirring efficiency and benefiting the later use of the material.

Description

Technical Field

[0001] This utility model relates to the field of polyester powder coating production, and in particular to a reaction vessel for producing high-temperature resistant polyester powder coating. Background Technology

[0002] Polyester-based powder coatings are thermosetting powder coatings composed of polyester resin, curing agent, pigment, filler and additives. They are characterized by being solvent-free, low-pollution, high-efficiency, low-cost and weather-resistant, and are widely used in automobiles, furniture, home appliances and other fields.

[0003] Existing reactors generally use mechanical stirring to agitate materials. However, polyester powder coatings have a high density, and mechanical stirring may result in uneven mixing and low stirring efficiency, thus affecting the later use of the materials. To address this issue, we propose a high-temperature resistant reactor for the production of polyester powder coatings. Utility Model Content

[0004] The purpose of this invention is to provide a reaction vessel for producing high-temperature resistant polyester powder coatings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A reactor for producing high-temperature resistant polyester powder coatings includes a reactor body, a feed hopper connected to the upper surface of the reactor body, a heat insulation layer (a nano-anti-corrosion and heat-insulating coating) connected to the inner wall of the reactor body, a first motor connected to the upper surface of the reactor body, a first rotating column connected to the output end of the first motor, a first bearing embedded in the inner top wall of the reactor body, the inner ring of the first bearing connected to the outer surface of the first rotating column, two adjusting rods connected to the outer surface of the first rotating column, and stirring rods connected to the upper surfaces of the two adjusting rods, two second motors connected to the upper surface of the reactor body, and second rotating columns connected to the output ends of the two second motors, two second bearings embedded in the inner top wall of the reactor body, the inner rings of the two second bearings connected to the outer surfaces of the two second rotating columns, and first helical blades connected to the outer surfaces of the two second rotating columns.

[0007] In a further embodiment, a support assembly is connected to the bottom surface of the reactor body. The support assembly includes multiple support columns, and a base is connected to the bottom surface of each support column.

[0008] In a further embodiment, the bottom surface of the reactor body is connected to a discharge assembly, the discharge assembly including a discharge pipe, and the outer surface of the discharge pipe is connected to a discharge valve.

[0009] In a further embodiment, the upper surface of the feed hopper is hinged with a protective assembly, which includes two cover plates, each with a pull rod connected to its upper surface.

[0010] In a further embodiment, a feeding assembly is connected to the upper surface of the feeding hopper. The feeding assembly includes a third motor and a third bearing. The third bearing is located on the inner bottom wall of the feeding hopper. The output end of the third motor is connected to a third rotating column. The inner ring of the third bearing is connected to the outer surface of the third rotating column. A second helical blade is connected to the outer surface of the third rotating column.

[0011] In a further embodiment, each of the two adjusting rods is connected to a cleaning component on its opposite side. Each cleaning component includes an adjusting plate, and each adjusting plate is connected to a brush on its opposite side. The opposite sides of each brush are in contact with the interior of the reactor body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses a first motor to drive a first rotating column to rotate, which in turn causes an adjusting rod to drive a stirring rod to rotate on the outer surface of the first rotating column, thus stirring the material. A second motor is then activated to drive a second rotating column to rotate, causing a first spiral blade to rotate on the outer surface of the second rotating column, thereby stirring the material. This prevents the material from overheating and clumping. The first spiral blade and the stirring rod work together to ensure more thorough and uniform stirring, improving stirring efficiency and benefiting the later use of the material.

[0023] Please see Figure 1-5This utility model discloses a high-temperature resistant polyester powder coating production reactor, comprising a reactor body 1, a feed hopper 7 connected to the upper surface of the reactor body 1, a heat insulation layer 17 connected to the inner wall of the reactor body 1, the heat insulation layer 17 being a nano-anti-corrosion and heat-insulating coating, a first motor 8 connected to the upper surface of the reactor body 1, a first rotating column 9 connected to the output end of the first motor 8, a first bearing 10 embedded in the inner top wall of the reactor body 1, the inner ring of the first bearing 10 connected to the outer surface of the first rotating column 9, two adjusting rods 11 connected to the outer surface of the first rotating column 9, a stirring rod 12 connected to the upper surface of each of the two adjusting rods 11, and two second motors 13 connected to the upper surface of the reactor body 1, the output ends of each of the two second motors 13 connected to a second rotating column 14. Two second bearings 15 are embedded in the inner top wall of the vessel body 1. The inner rings of the two second bearings 15 are connected to the outer surface of the second rotating column 14. The outer surfaces of the two second rotating columns 14 are connected to first spiral blades 16. The first motor 8 drives the first rotating column 9 to rotate, which causes the adjusting rod 11 to drive the stirring rod 12 to rotate on the outer surface of the first rotating column 9, thereby stirring the material. The second motor 13 is started to drive the second rotating column 14 to rotate, which causes the first spiral blades 16 to rotate on the outer surface of the second rotating column 14, thereby stirring the material. Through the coordinated use of the first spiral blades 16 and the stirring rod 12, they complement each other, making the material more thoroughly and evenly stirred, improving the stirring efficiency, and benefiting the later use of the material.

[0024] A support assembly 2 is connected to the bottom surface of the reactor body 1. The support assembly 2 includes multiple support columns 201, and a base 202 is connected to the bottom surface of each support column 201. Through the cooperation of the support columns 201 and the base 202, the reactor body 1 can be effectively supported, preventing shaking during use and increasing the stability of the reactor body 1. A discharge assembly 3 is connected to the bottom surface of the reactor body 1. The discharge assembly 3 includes a discharge pipe 301, and a discharge valve 302 is connected to the outer surface of the discharge pipe 301. Through the cooperation of the discharge pipe 301 and the discharge valve 302, the reactor body 1 can effectively support the reactor body 1, preventing shaking during use and increasing the stability of the reactor body 1. This device can effectively discharge evenly mixed materials, increasing ease of use. Specifically, the inside of the discharge pipe 301 is coated with antistatic paint, and the upper surface of the feed hopper 7 is hinged with a protective component 4. The protective component 4 includes two cover plates 401, and the upper surface of each cover plate 401 is connected to a pull rod 402. The cooperation of the cover plates 401 and the pull rods 402 can effectively protect the internal parts of the reactor body 1 from dust, thereby preventing damage to the internal parts, increasing the service life of the device, and reducing the maintenance cost of the device.

[0025] A feeding assembly 5 is connected to the upper surface of the feeding hopper 7. The feeding assembly 5 includes a third motor 501 and a third bearing 503. The third bearing 503 is located on the inner bottom wall of the feeding hopper 7. The output end of the third motor 501 is connected to a third rotating column 502. The inner ring of the third bearing 503 is connected to the outer surface of the third rotating column 502. A second spiral blade 504 is connected to the outer surface of the third rotating column 502. The third motor 501 drives the third rotating column 502 to rotate using the third bearing 503, thereby causing the second spiral blade 504 to rotate on the outer surface of the third rotating column 502. This allows the second spiral blade 504 to convey the material, efficiently moving the material from the feeding hopper. The material is conveyed from the hopper 7 into the reactor body 1. This continuous pushing method ensures uniform material delivery and avoids blockage and accumulation during the delivery process. Cleaning components 6 are connected to the opposite sides of the two adjusting rods 11. Each cleaning component 6 includes an adjusting plate 601. Each adjusting plate 601 has a brush 602 connected to its opposite side. The opposite sides of each brush 602 are in contact with the interior of the reactor body 1. The adjustment plate 601 is rotated by rotating the adjusting rod 11, which in turn drives the brush 602 to rotate, thereby cleaning the inner wall of the reactor body 1 and avoiding material waste.

[0026] The working principle of this utility model is as follows:

[0027] In use, the first motor 8 is started, causing the first rotating column 9 to rotate using the first bearing 10. This causes the adjusting rod 11 to drive the stirring rod 12 to rotate on the outer surface of the first rotating column 9, thereby causing the stirring rod 12 to stir the material. At the same time, the second motor 13 is started, causing the second rotating column 14 to rotate using the second bearing 15. This causes the first spiral blade 16 to rotate on the outer surface of the second rotating column 14, thereby causing the first spiral blade 16 to stir the material.
