Abstract
Description
Technical Field
[0001] This application relates to the field of coating production, and more specifically, to a feeding device for a coating reaction vessel. Background Technology
[0002] As the "reaction center" in paint production, the paint reaction vessel is used to complete chemical reactions such as resin synthesis (e.g., alkyd, polyurethane, acrylic resin), emulsion polymerization, esterification, and condensation. Raw materials are fed into the vessel in proportion through a feeding device (e.g., screw pump, negative pressure suction system), and the agitator is activated to achieve uniform mixing and reduce local concentration differences.
[0003] However, the existing feeding devices for coating reactors still have the following shortcomings during use: The output end of most existing feeding devices extends directly into the interior of the reactor, directly inputting the raw materials into the reactor. However, the output end of most existing feeding devices is set in a fixed position, which makes it impossible for the raw materials to be added evenly into the interior of the reactor. The added raw materials can only be stirred by the stirring mechanism to fully mix with the raw materials inside the reactor, resulting in low mixing efficiency. Utility Model Content
[0004] To overcome the above shortcomings, this application provides a feeding device for a coating reaction vessel, which aims to improve the problem that the output end of the existing feeding device is mostly set in a fixed position, which leads to the raw materials not being added evenly into the interior of the reaction vessel. The raw materials can only be stirred by a stirring mechanism to ensure that the added raw materials are fully mixed with the raw materials inside the reaction vessel, resulting in low mixing efficiency.
[0005] This application provides a feeding device for a coating reaction vessel, used to transport raw materials from inside a raw material tank to the interior of the reaction vessel body. The interior of the reaction vessel body is provided with a conveying mechanism for transporting the raw materials and a stirring mechanism for stirring the raw materials. The material conveying mechanism includes multiple sets of second pipes, one end of which is connected to a nozzle. The nozzle is located inside the reactor body. The other end of each set of second pipes passes through the reactor body and is connected to the same set of first pipes. The other end of the first pipe is connected to the output end of the raw material tank.
[0006] In the above implementation process, through the setting of the first pipeline, the raw materials inside the raw material tank are transported to the inside of the first pipeline through the output component, then to the inside of the second pipeline, and then sprayed into the inside of the reactor body through the nozzle. The output component is existing technology, such as a screw pump, which will not be described in detail here.
[0007] In one specific implementation, a first circular plate is connected inside the reactor body, a motor is connected to the top of the reactor body, the output shaft of the motor passes through the reactor body and the first circular plate and is connected to a rotating component, and the rotating component is rotatably connected to the bottom of the first circular plate.
[0008] In the above implementation process, by setting up the motor, the output shaft of the motor can be controlled to rotate, which drives the rotating part to rotate at the bottom of the first circular plate, while the first circular plate does not rotate.
[0009] In one specific implementation, the bottom of the rotating component is connected to a second circular plate, and the top of the second circular plate has multiple sets of sliding grooves.
[0010] In the above implementation process, by setting the rotating component, the second circular plate can be driven to rotate inside the reactor body when the rotating component rotates.
[0011] In one specific implementation, the bottom of the first circular plate is connected to multiple sets of moving tracks, the inside of the moving tracks is slidably connected to a moving component, the outer surface of the moving component is connected to a sliding component, the sliding component slides inside the sliding groove, and the sliding component is connected to the mounting end of the nozzle.
[0012] In the above implementation process, by setting the sliding groove, when the second circular plate rotates, the sliding member can be driven to slide inside the sliding groove. Since one end of the sliding member is connected to the moving member, the moving member is driven to move horizontally inside the moving track, so that the sliding member can only slide in the horizontal direction of the moving track. The sliding member drives the nozzle to move and adjusts the position of multiple sets of nozzles, so that the raw material sprayed by the nozzle is evenly added into the interior of the reactor body, which can improve the mixing efficiency of the added raw material with the raw material inside the reactor.
[0013] In one specific implementation, the stirring mechanism includes a first vertical rod connected to the bottom of a second circular plate, and a plurality of stirring rods are connected to the outer surface of the first vertical rod.
[0014] In the above implementation process, by setting the first vertical rod, when the motor drives the second circular plate to rotate, the first vertical rod will rotate, which in turn will drive the stirring rod to rotate. This allows the raw materials inside the reactor body to be stirred by the stirring rod while the raw materials are being added, thereby improving the efficiency of raw material mixing.
[0015] In one specific implementation, a cavity is formed at the bottom of the first vertical rod, and a second vertical rod is slidably connected inside the cavity. A spring is connected to the top of the second vertical rod, and the other end of the spring is connected to the inner wall of the cavity.
[0016] In the above implementation process, by setting the spring, the spring can be compressed and set inside the cavity. The elastic potential energy released by the spring makes the bottom of the stirring piece tightly adhere to the inner wall of the reactor body. When the first vertical rod rotates, the second vertical rod will rotate together with the first vertical rod.
[0017] In one specific implementation, the bottom of the second vertical rod is connected to a connector, and the outer surface of the connector is connected to multiple sets of stirring components, with inclined surfaces on both sides of each stirring component.
[0018] In the above process, by setting the inclined surface, the stirring component can be driven to rotate when the second vertical rod rotates. The inclined surface causes the raw materials deposited at the bottom of the reactor body to surge upward, thereby improving the mixing efficiency of the raw materials in the reactor body.
[0019] Compared with the prior art, the beneficial effects of this application are as follows: By setting up the feeding mechanism and the stirring mechanism, the output shaft of the motor can be controlled to rotate, driving the rotating part to rotate at the bottom of the first circular plate, driving the second circular plate to rotate inside the reactor body, and driving the sliding part to slide inside the sliding groove. Since one end of the sliding part is connected to the moving part, the moving part is driven to move horizontally inside the moving track, so that the sliding part can only slide in the horizontal direction of the moving track. The sliding part drives the nozzle to move, and the position of multiple sets of nozzles can be adjusted so that the raw materials sprayed from the nozzles are evenly added into the reactor body, which can improve the mixing efficiency of the added raw materials with the raw materials inside the reactor. When the second circular plate rotates, it drives the first vertical rod to rotate, which in turn drives the stirring rod to rotate. This allows the raw materials inside the reactor body to be stirred simultaneously with the addition of raw materials. When the first vertical rod rotates, the second vertical rod will rotate along with it, causing the stirring component to rotate as well. The inclined surface creates an upward surge of raw materials deposited at the bottom of the reactor body, improving the mixing efficiency of the raw materials inside the reactor body. This solves the problem that most existing feeding devices have their output ends set in fixed positions, resulting in uneven addition of raw materials into the reactor body. The only solution is to rely on the stirring mechanism to ensure thorough mixing of the added raw materials with the materials inside the reactor, leading to low mixing efficiency.

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0024] Please see Figure 1 and Figure 2 This application provides a feeding device for a coating reaction vessel, which is used to transport the raw materials inside the raw material tank 1 to the inside of the reaction vessel body 5. The inside of the reaction vessel body 5 is provided with a conveying mechanism 2 for conveying the raw materials, and a stirring mechanism 3 for stirring the raw materials.
[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The material conveying mechanism 2 includes multiple sets of second pipes 209. One end of each set of second pipes 209 is connected to a nozzle 2010, which is located inside the reactor body 5. The other end of each set of second pipes 209 passes through the reactor body 5 and is connected to the same set of first pipes 4. The other end of the first pipe 4 is connected to the output end of the raw material tank 1. Through the first pipe 4, the raw material inside the raw material tank 1 is transported to the inside of the first pipe 4 via the output component, then to the inside of the second pipe 209, and finally sprayed into the inside of the reactor body 5 via the nozzle 2010. The output component is existing technology, such as a screw pump, which will not be described in detail here.
[0026] In the specific setup, a first circular plate 202 is connected inside the reactor body 5, and a motor 201 is connected to the top of the reactor body 5. The output shaft of the motor 201 passes through the reactor body 5 and the first circular plate 202 and is connected to a rotating component 204. The rotating component 204 is rotatably connected to the bottom of the first circular plate 202. By controlling the output shaft of the motor 201 to rotate, the rotating component 204 can be driven to rotate at the bottom of the first circular plate 202, while the first circular plate 202 does not rotate.
[0027] In a specific configuration, the bottom of the rotating component 204 is connected to a second circular plate 203, and the top of the second circular plate 203 has multiple sets of sliding grooves 207. Through the configuration of the rotating component 204, the second circular plate 203 can be driven to rotate inside the reactor body 5 when the rotating component 204 rotates.
[0028] In a specific configuration, the bottom of the first circular plate 202 is connected to multiple sets of moving tracks 205. Moving parts 206 are slidably connected inside the moving tracks 205, and sliding parts 208 are connected to the outer surface of the moving parts 206. The sliding parts 208 slide inside the sliding groove 207 and are connected to the mounting end of the nozzle 2010. The sliding groove 207 allows the sliding parts 208 to slide inside the sliding groove 207 when the second circular plate 203 rotates. Since one end of the sliding part 208 is connected to the moving part 206, the moving part 206 moves horizontally inside the moving tracks 205, allowing the sliding part 208 to slide only in the horizontal direction of the moving tracks 205. The sliding part 208 moves the nozzle 2010, adjusting the position of the multiple sets of nozzles 2010 so that the raw materials sprayed from the nozzles 2010 are evenly added into the reactor body 5, improving the mixing efficiency of the added raw materials with the raw materials inside the reactor.
[0029] In a specific configuration, the stirring mechanism 3 includes a first vertical rod 301, which is connected to the bottom of the second circular plate 203. Multiple sets of stirring rods 302 are connected to the outer surface of the first vertical rod 301. By setting the first vertical rod 301, when the motor 201 drives the second circular plate 203 to rotate, the first vertical rod 301 is driven to rotate, which in turn drives the stirring rods 302 to rotate. This allows the stirring rods 302 to stir the raw materials inside the reactor body 5 while the raw materials are being added, thereby improving the efficiency of raw material mixing.
[0030] In a specific configuration, a cavity 303 is provided at the bottom of the first vertical rod 301. A second vertical rod 304 is slidably connected inside the cavity 303. A spring 305 is connected to the top of the second vertical rod 304. The other end of the spring 305 is connected to the inner wall of the cavity 303. The spring 305 can be compressed and placed inside the cavity 303. The elastic potential energy released by the spring 305 causes the bottom of the stirring element 307 to be in close contact with the inner wall of the reactor body 5. When the first vertical rod 301 rotates, the second vertical rod 304 will rotate together with the first vertical rod 301.
[0031] In a specific configuration, a connector 306 is connected to the bottom of the second vertical rod 304. Multiple sets of stirring elements 307 are connected to the outer surface of the connector 306. Inclined surfaces 308 are provided on both sides of the stirring elements 307. The inclined surfaces 308 enable the stirring elements 307 to rotate when the second vertical rod 304 rotates. The inclined surfaces 308 also cause the raw materials deposited at the bottom of the reactor body 5 to rise upwards, thereby improving the mixing efficiency of the raw materials in the reactor body 5.
[0032] The working principle of the feeding device for the coating reactor is as follows: When using the feeding device for the coating reactor, the raw material inside the raw material tank 1 can be transported through the output component to the inside of the first pipe 4, then to the inside of the second pipe 209, and then sprayed into the inside of the reactor body 5 through the nozzle 2010. By controlling the output shaft of the motor 201 to rotate, the rotating part 204 is driven to rotate at the bottom of the first circular plate 202, which in turn drives the second circular plate 203 to rotate inside the reactor body 5. This causes the sliding part 208 to slide inside the sliding groove 207. Since one end of the sliding part 208 is connected to the moving part 206, the moving part 206 is driven to move horizontally inside the moving track 205, so that the sliding part 208 can only slide in the horizontal direction of the moving track 205. The sliding part 208 drives the nozzle 2010 to move. By adjusting the position of the multiple sets of nozzles 2010, the raw material sprayed by the nozzles 2010 can be adjusted. The material is evenly added into the interior of the reactor body 5, which improves the mixing efficiency between the added material and the material inside the reactor. When the motor 201 drives the second circular plate 203 to rotate, it drives the first vertical rod 301 to rotate, which in turn drives the stirring rod 302 to rotate. This allows the material inside the reactor body 5 to be stirred simultaneously with the addition of the material. When the first vertical rod 301 rotates, the second vertical rod 304 will rotate along with it, driving the stirring element 307 to rotate. Through the inclined surface 308, the material deposited at the bottom of the reactor body 5 is allowed to surge upward, improving the mixing efficiency of the material inside the reactor body 5. This solves the problem that most existing feeding devices have their output ends set in fixed positions, resulting in the material not being evenly added into the reactor. The material can only be stirred by the stirring mechanism 3 to ensure that the added material is fully mixed with the material inside the reactor, resulting in low mixing efficiency.
[0033] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
