Abstract
Description
Technical Field
[0001] This utility model relates to the field of curing agent production technology, specifically a mixing reaction vessel for curing agent production. Background Technology
[0002] Curing agents, also known as hardeners, ripening agents, or stabilizers, are substances or mixtures that enhance or control the curing reaction. Resin curing is an irreversible process that occurs in thermosetting resins through chemical reactions such as condensation, ring closure, addition, or catalysis. Curing is accomplished by adding curing (crosslinking) agents. Curing agents are essential additives; they are required in adhesives, coatings, and casting materials, otherwise epoxy resins cannot cure. In the curing agent production process, the mixing reactor is one of the core pieces of equipment, and its performance directly affects the product quality and production efficiency of the curing agent.
[0003] Currently, the discharge structure design of some mixing reactors is not reasonable enough. Because the curing agent material has a certain viscosity, it is easy to accumulate in the discharge pipe, resulting in poor discharge or even blockage, which prolongs the discharge time and reduces production efficiency.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a mixing reactor for the production of curing agents. Utility Model Content
[0005] The purpose of this invention is to provide a mixing reactor for the production of curing agents, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing reactor for producing a curing agent, comprising a reactor body and a servo motor. A cylinder is provided at the top of the reactor body, and a feeding channel is provided at the top of the cylinder. The servo motor is located on the right side of the feeding channel, and the output end of the servo motor is connected to an auger. A synchronous pulley is sleeved on the outside of the auger, and a synchronous pulley is connected to the outside of the synchronous pulley via a synchronous belt. A transmission rod passes through the middle of the synchronous pulley, and a bevel gear is provided at the right end of the transmission rod. A bevel gear is connected to the outside of the bevel gear, and a stirring shaft passes through the middle of the bevel gear. A stirring paddle is provided on the outside of the stirring shaft, and a scraper is connected to the other end of the stirring paddle. An auger is provided at the bottom end of the stirring shaft, and a protective shell is provided at the bottom center of the feeding channel.
[0007] Furthermore, a support leg is fixed at the edge of the bottom of the vessel body, and a discharge pipe is provided at the middle of the bottom of the vessel body, with a valve installed on the discharge pipe.
[0008] Furthermore, a feeding pipe is provided on the top left side of the feeding channel, and a feeding pipe is provided on the bottom right side of the feeding channel.
[0009] Furthermore, the second feeding pipe passes through the opening on the right side of the top of the vessel, and the stirring shaft passes through the opening at the middle of the top of the vessel.
[0010] Furthermore, the auger and the transmission rod are parallel to each other, and the transmission rod is located inside the bearing at the opening on the left side of the protective shell.
[0011] Furthermore, the transmission rod and the stirring shaft are perpendicular to each other, and the stirring shaft is disposed in the bearing at the bottom opening of the protective shell.
[0012] Furthermore, the discharge pipe and the second auger are coaxially arranged, and the first auger and the second auger are perpendicular to each other.
[0013] This utility model provides a mixing reactor for producing curing agents, which has the following beneficial effects:
[0014] 1. This utility model starts the servo motor, which transmits power to the first synchronous pulley through the auger. The synchronous belt meshes with the first and second synchronous pulleys to transmit power, causing the transmission rod and the first bevel gear to rotate, which in turn drives the second bevel gear to rotate. This enables the stirring shaft and stirring paddle to stir the material. When working with the cylinder, the stirring height of the stirring paddle can be flexibly adjusted to achieve stirring of the material in the vessel at different heights, thereby improving the uniformity of stirring.
[0015] 2. The scraper of this utility model adopts a composite structure of high-temperature resistant rubber (fluororubber) and stainless steel frame. When the auger rotates, the scraper simultaneously scrapes off the material adhering to the inner wall of the vessel, which greatly improves the material feeding speed, prevents the material from blocking the discharge pipe, ensures smooth discharge, and facilitates the cleaning of the inner wall of the vessel.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0021] like Figure 1 and Figure 2 As shown, a mixing reactor for producing a curing agent includes a reactor body 1 and a servo motor 9. A cylinder 5 is mounted on the top of the reactor body 1, and a feeding channel 6 is mounted on the top of the cylinder 5. A feeding pipe 7 is mounted on the top left side of the feeding channel 6, and a feeding pipe 8 is mounted on the bottom right side of the feeding channel 6. The servo motor 9 is located on the right side of the feeding channel 6, and its output end is connected to an auger 10. A synchronous pulley 11 is fitted around the auger 10, and a synchronous pulley 13 is connected to the outside of the synchronous pulley 11 via a synchronous belt 12. A transmission rod 14 is inserted through the middle of the first 11, and a bevel gear 15 is provided at the right end of the transmission rod 14. A bevel gear 16 is connected to the outside of the bevel gear 15, and a stirring shaft 17 is inserted through the middle of the bevel gear 16. A stirring paddle 18 is provided on the outside of the stirring shaft 17. A protective shell 21 is provided at the bottom middle of the feeding channel 6. The auger 10 and the transmission rod 14 are parallel to each other. The transmission rod 14 is located in the bearing at the left opening of the protective shell 21. The transmission rod 14 and the stirring shaft 17 are perpendicular to each other. The stirring shaft 17 is located in the bearing at the bottom opening of the protective shell 21.
[0022] The specific operation is as follows: Start the servo motor 9, so that the power is transmitted to the synchronous pulley 11 through the auger 10. The synchronous belt 12 meshes with the synchronous pulley 11 and the synchronous pulley 13 to transmit power, so that the transmission rod 14 and the bevel gear 15 rotate, which in turn drives the bevel gear 16 to rotate, so that the stirring shaft 17 and the stirring paddle 18 can stir the material. In conjunction with the cylinder 5, the stirring height of the stirring paddle 18 can be flexibly adjusted to stir the material in the vessel 1 at different heights, thereby improving the uniformity of stirring.
[0023] like Figure 2 and Figure 3 As shown, a support leg 2 is fixed at the bottom edge of the vessel body 1, and a discharge pipe 3 is provided at the middle of the bottom of the vessel body 1. A valve 4 is installed on the discharge pipe 3. A feeding pipe 8 passes through the opening on the right side of the top of the vessel body 1. A stirring shaft 17 passes through the opening at the middle of the top of the vessel body 1. A scraper 19 is connected to the other end of the stirring paddle 18. A screw conveyor 20 is provided at the bottom of the stirring shaft 17. The discharge pipe 3 and the screw conveyor 20 are coaxially arranged, and the screw conveyor 10 and the screw conveyor 20 are perpendicular to each other.
[0024] The specific operation is as follows: the scraper plate 19 adopts a composite structure of high temperature resistant rubber (fluororubber) and stainless steel skeleton. When the auger 20 rotates, the scraper plate 19 scrapes off the material adhering to the inner wall of the vessel body 1, which greatly improves the material feeding speed, prevents the material from blocking the discharge pipe 3, ensures smooth discharge, and facilitates the cleaning of the inner wall of the vessel body 1.
[0025] In summary, when using the mixing reactor for producing this curing agent, the material is first fed into the feeding channel 6 through the feeding pipe 7, and the auger 10 is rotated by the servo motor 9 to push the material along the length of the feeding channel 6, realizing the conveying from the left end to the right end, until it reaches the feeding pipe 8 and falls into the reactor body 1. The continuous pushing action of the auger 10 reduces the accumulation and agglomeration of the material, and at the same time, it allows the material to be mixed in advance during the conveying process, reducing the subsequent load.
[0026] During the operation of the servo motor 9, the power is transmitted to the synchronous pulley 11 via the auger 10. The synchronous belt 12 meshes with the synchronous pulley 11 and the synchronous pulley 13 to transmit power, causing the transmission rod 14 and the bevel gear 15 to rotate, which in turn drives the bevel gear 16 to rotate. This enables the stirring shaft 17 and the stirring paddle 18 to stir the material. With the cylinder 5 extending or retracting, the height of the feeding channel 6, the protective shell 21, and the stirring paddle 18 can be flexibly adjusted, allowing the stirring paddle 18 to stir the material in the vessel 1 at different heights, further improving the uniformity of stirring.
[0027] During this period, the scraper 19 moves close to the inner wall of the vessel 1, scraping off the attached material and pushing it to the mixing area, forming a synergistic effect of mixing and scraping, so as to eliminate dead corners and improve the uniformity of mixing. After mixing is completed, the valve 4 is opened, and the cylinder 5 is controlled to retract and drive the auger 20 to move down. The auger 20 pushes the material to ensure smooth discharge and avoid blockage of the material in the discharge pipe 3.

Many modifications and variations will be apparent to those skilled in the art.
