Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel for processing anti-corrosion coatings. Background Technology

[0002] The anti-corrosion coating processing reactor is a key device used in the production process of anti-corrosion coatings. It is usually composed of a reactor body, a stirrer, a heating or cooling system, a sealing device, and inlet and outlet ports. Through the action of the stirrer, various raw materials of anti-corrosion coatings, such as resins, pigments, fillers, solvents and various additives, can be fully mixed evenly to ensure that the proportion of each component of the coating is accurate and the performance is stable.

[0003] Traditional anti-corrosion coating processing reactors typically only have basic stirring functions, with a single type of stirring mechanism. The movement trajectory of materials within the reactor is limited, resulting in uneven mixing and incomplete reaction of raw materials. This makes it difficult to meet the production requirements of high-quality anti-corrosion coatings. Furthermore, the scraper of conventional reactors is inconvenient to disassemble. When the scraper wears out and needs to be replaced, the disassembly operation is cumbersome, time-consuming, and labor-intensive, extending equipment maintenance time and reducing production efficiency. Based on these issues, an improved anti-corrosion coating processing reactor is proposed. Utility Model Content

[0004] In view of the problems of the existing stirring mechanism being of a single form, having a limited movement trajectory, and the inconvenience of disassembling the scraper of a conventional reaction vessel, this utility model is proposed.

[0006] A lifting motor is fixedly installed at the center of the top of the end cover by bolts. The output shaft of the lifting motor passes through the top of the end cover and is fixedly sleeved with a reciprocating screw. The reciprocating screw is set inside the hollow rotating cylinder, and the bottom end of the reciprocating screw is rotatably connected to the top of the mounting block.

[0007] The reciprocating lead screw has a threaded sleeve on its outer surface. Several connecting blocks are fixedly connected to the bottom end of the threaded sleeve. The bottom ends of the connecting blocks are fixedly connected to the upper end of the same inner ring of a bearing. Several arc-shaped lifting plates are fixedly connected to the lower end of the outer ring of the bearing. The bottom ends of the arc-shaped lifting plates pass through the internal groove of the fixed circular plate and are fixedly connected to the same limiting block. The limiting block is slidably connected to the internal groove of the stirring shaft. Wing-shaped stirring blades are fixedly connected to the outer surface of the arc-shaped lifting plates.

[0008] As a preferred embodiment, a support frame is fixedly installed at the bottom of the reactor body, a stirring motor is fixedly installed at the top inside the support frame, and the output shaft of the stirring motor is fixedly sleeved at the bottom of the stirring shaft.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] 1. This utility model uses a stirring rod in the stirring mechanism to rotate with the stirring shaft to perform conventional stirring of the raw materials in the reactor.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a reaction vessel for processing anti-corrosion coatings, including a reaction vessel body 1, a stirring shaft 22 rotatably connected to the bottom wall of the reaction vessel body 1, an end cover 11 fixedly installed at the top of the reaction vessel body 1, a hollow rotating cylinder 25 rotatably connected to the inner wall of the end cover 11, a bearing 37 provided inside the hollow rotating cylinder 25, a fixed circular plate 34 fixedly connected to the bottom end of the hollow rotating cylinder 25, an installation block 33 fixedly installed at the top of the fixed circular plate 34, and a stirring mechanism 2 and a lifting mechanism 3 provided inside the reaction vessel body 1;

[0025] A lifting motor 31 is fixedly installed at the center of the top of the end cover 11 by bolts. The output shaft of the lifting motor 31 passes through the top of the end cover 11 and is fixedly sleeved with a reciprocating screw 32. The reciprocating screw 32 is set inside the hollow rotating cylinder 25, and the bottom end of the reciprocating screw 32 is rotatably connected to the top of the mounting block 33.

[0026] A threaded sleeve 35 is threaded onto the outer surface of the reciprocating lead screw 32. Several connecting blocks 36 are fixedly connected to the bottom end of the threaded sleeve 35. The bottom ends of the connecting blocks 36 are fixedly connected to the upper end of the inner ring of the same bearing 37. Several arc-shaped lifting plates 38 are fixedly connected to the lower end of the outer ring of the bearing 37. The bottom ends of the arc-shaped lifting plates 38 pass through the internal groove of the fixed circular plate 34 and are fixedly connected to the same limiting block 310. The limiting block 310 is slidably connected to the internal groove of the stirring shaft 22. Wing-shaped stirring blades 39 are fixedly connected to the outer surface of the arc-shaped lifting plates 38.

[0027] A support frame 14 is fixedly installed at the bottom of the reactor body 1. A stirring motor 21 is fixedly installed at the top inside the support frame 14. The output shaft of the stirring motor 21 is fixedly sleeved at the bottom of the stirring shaft 22.

[0028] Several C-shaped connecting rods 23 are fixedly connected to the surface of the stirring mechanism 2. Scrapers 42 are provided on the outer side of the C-shaped connecting rods 23. Stirring rods 24 are fixedly connected to the inner side of the C-shaped connecting rods 23. The top ends of the C-shaped connecting rods 23 are fixedly connected to the surface of the hollow rotating cylinder 25.

[0029] Specifically, the stirring motor 21 is started first, and its output shaft drives the stirring shaft 22 to rotate. The stirring shaft 22 drives several C-shaped connecting rods 23 to rotate accordingly. The C-shaped connecting rods 23 drive the stirring rod 24 and the scraper 42 to rotate, thereby stirring the anti-corrosion coating raw materials in the reactor body 1, so that the raw materials are fully mixed and reacted. During the rotation, the scraper 42 cleans the inner wall of the reactor body 1 to prevent the raw materials from adhering to the reactor wall. At the same time, the stirring shaft 22 drives the hollow rotating cylinder 25 to rotate through the C-shaped connecting rods 23.

[0030] Next, the lifting motor 31 is started, and its output shaft drives the reciprocating screw 32 to rotate. When the reciprocating screw 32 rotates, the screw sleeve 35 will move up and down along the reciprocating screw 32 under the action of the thread. The screw sleeve 35 is connected to the bearing 37 through the connecting block 36, which in turn drives the arc-shaped lifting plate 38 to move up and down. The bearing 37 is used to separate the rotational motion of the reciprocating screw 32 and the rotational motion of the stirring mechanism 2 to prevent them from affecting each other. The limiting block 310 at the bottom of the arc-shaped lifting plate 38 slides in the internal groove of the stirring shaft 22, which plays a limiting and guiding role in the movement of the arc-shaped lifting plate 38, ensuring its stable lifting. As the arc-shaped lifting plate 38 rises and falls, the wing-shaped stirring blades 39 on its outer surface will also move up and down in the reactor body 1 to stir the raw materials at different heights, further improving the stirring effect.

[0031] This design uses the stirring rod 24 in the stirring mechanism 2 to rotate with the stirring shaft 22 to perform conventional stirring of the raw materials in the reactor body 1, while the lifting mechanism 3 drives the wing-shaped stirring blades 39 to move up and down. The combination of the two ensures that the raw materials can be fully stirred in both horizontal and vertical directions, avoiding uneven stirring in certain areas. This makes the anti-corrosion coating raw materials more uniformly mixed and the reaction more complete, which helps to improve product quality.

[0032] Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a quick-release mechanism 4 is also provided inside the reactor body 1. A limiting plate 41 is inserted into the outer slot of the C-shaped connecting rod 23. A scraper 42 is fixedly connected to the outer side of the limiting plate 41. One end of the scraper 42 is in contact with the inner wall of the reactor body 1.

[0033] A limiting bolt 43 is provided on one side of the limiting plate 41. One end of the limiting bolt 43 passes through the top of the limiting plate 41 and is threaded into the C-shaped connecting rod 23.

[0034] Specifically, when the scraper 42 needs to be disassembled for replacement, the limiting bolt 43 is rotated in the opposite direction to remove it from inside the C-shaped connecting rod 23. After the limiting bolt 43 is loosened, the limiting plate 41 can be pulled out from the slot on the outside of the C-shaped connecting rod 23, and then the scraper 42 can be removed, completing the quick disassembly process. By simply inserting the limiting plate 41 and fixing it with the limiting bolt 43, the installation and disassembly of the scraper 42 can be completed in a short time without complicated operations, reducing equipment maintenance downtime and improving overall production efficiency.

[0035] Reference Figures 1-5 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that: a feed pipe 12 is fixedly sleeved on one side of the top of the end cap 11, a discharge pipe 13 is fixedly sleeved on one side of the bottom of the reactor body 1, and a heating pipe 15 is fixedly installed inside the side wall of the reactor body 1.

[0036] During use, various raw materials required for the reaction can be fed into the reactor body 1 through the feed pipe 12, the products after the reaction are discharged through the discharge pipe 13, and the heating pipe 15 is used to provide the heat required for the reaction.
