[0003] The aforementioned reactor has certain defects during use. For example, the reactor is used to inject reaction raw materials into the reactor through the first feed pipe. When liquid raw materials are injected into the reactor through the first feed pipe, some liquid raw materials will adhere to the inner wall of the first feed pipe, resulting in a waste of chemical resources. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art:

[0005] The existing reactor uses a first feed pipe to inject reaction materials into the reactor. When liquid materials are injected into the reactor through the first feed pipe, some of the liquid materials will adhere to the inner wall of the first feed pipe, resulting in a waste of chemical resources.

[0006] An automatic constant temperature and pressure reactor was proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solutions:

[0008] An automatic constant temperature and pressure reactor includes a reactor body. A feed pipe is fixedly installed through the upper end face of the reactor body. A rotating ring is rotatably installed at the inner top of the reactor body and directly below the feed pipe. A scraper is movably installed on the inner wall of the rotating ring. A counterweight is fixed to the lower end face of the scraper. A stirring shaft is rotatably installed between the inner top and inner bottom of the reactor body. A motor for use with the stirring shaft is fixed to the upper end face of the reactor body. A transmission assembly is installed between the stirring shaft and the rotating ring. A material shaking assembly for use with the scraper and the counterweight is installed on the stirring shaft.

[0009] As a further technical solution of the present invention, a sliding groove is provided in the rotating ring, a sliding cylinder is slidably arranged in the sliding groove, a connecting column is fixed on the side of the sliding cylinder near the scraper, the connecting column movably passes through the rotating ring, and a reset member is provided between the sliding cylinder and the sliding groove.

[0010] As a further technical solution of the present invention, the reset component includes a spring fixed between the sliding cylinder and the inner wall of the sliding groove.

[0011] As a further technical solution of the present invention, the transmission assembly includes a gear ring one fixedly sleeved on the outer wall of the stirring shaft, and a gear ring two fixedly sleeved on the outer wall of the rotating ring, with gear ring one and gear ring two meshing and connected.

[0012] As a further technical solution of the present invention, a T-shaped rotating ring is fixed on the upper end face of the rotating ring, and a T-shaped rotating groove is opened on the inner top of the reactor body to cooperate with the T-shaped rotating ring. The T-shaped rotating ring and the T-shaped rotating groove are rotatably connected.

[0013] As a further technical solution of the present invention, the material shaking assembly includes a fixed sleeve fixed to the outer wall of the stirring shaft, one end of the fixed sleeve is provided with a sliding slot, a moving rod is slidably arranged in the sliding slot, and a reset member is provided between the moving rod and the sliding slot.

[0014] As a further technical solution of the present invention, the second reset component includes a telescopic rod fixed between the moving rod and the inner wall of the sliding slot, and a second spring is also fixed between the moving rod and the inner wall of the sliding slot, the second spring being movably sleeved on the outer wall of the telescopic rod.

[0015] As a further technical solution of the present invention, a scraping sleeve is fixedly sleeved at the end of the fixed sleeve, and the scraping sleeve is trumpet-shaped.

[0016] The beneficial effects of this invention are:

[0017] 1. During use, feed pipe 1 and other feed pipes are connected to multiple external material conveying pipes. When the external material conveying pipes inject liquid raw materials into the reactor body through feed pipe 1, a certain amount of liquid raw materials will adhere to the inner wall of feed pipe 1 as it passes through. After the initial feeding is completed, the valve on the corresponding material conveying pipe is closed. At this time, the motor drives the stirring shaft to rotate. The stirring shaft stirs and mixes the raw materials and auxiliary materials inside the reactor body. During this process, the stirring shaft drives the rotating ring and scraper to rotate through the transmission component. When the scraper rotates with the rotating ring, the side wall of the scraper will stick to the inner wall of feed pipe 1, thereby scraping off the liquid raw materials adhering to feed pipe 1. Then, under the guidance of gravity and the scraper, the liquid raw materials quickly drip down into the reactor body, avoiding the liquid raw materials adhering to the inner wall of feed pipe 1 and causing waste of chemical resources.

[0018] 2. In the initial state, spring one is in its normal position. At this time, there is a gap between the scraper and the rotating ring, and the side wall of the scraper is not in contact with the inner wall of the feed pipe one. Then, the motor drives the stirring shaft to rotate rapidly. When the rotating ring rotates rapidly, the scraper, connecting column, and sliding cylinder will move towards the rotating ring under the action of centrifugal force. During this process, the sliding cylinder will squeeze spring one, causing spring one to be compressed and store elastic potential energy. During this process, the side wall of the scraper will contact the inner wall of the feed pipe one, so that the rotating ring can drive the scraper to move towards the feed pipe one. The liquid raw materials adhering to the inner wall are scraped off. After scraping for a period of time, the motor speed is reduced, allowing the stirring shaft to return to its normal stirring speed. At this time, the rotation speed of the rotating ring decreases, and the centrifugal force on the scraper, connecting column, and sliding cylinder is smaller. The elastic potential energy stored in spring one is released, pushing the scraper, connecting column, and sliding cylinder back to their initial positions. At this time, the side wall of the scraper does not contact the inner wall of feed pipe one, so that the scraper does not perform scraping work under normal stirring operation of the stirring shaft, avoiding continuous contact between the scraper and the inner wall of feed pipe one, and avoiding unnecessary wear on the scraper.

[0019] 3. In the initial stage, when the motor drives the stirring shaft to stir rapidly, the stirring shaft drives the fixed sleeve and the moving rod to rotate together. At this time, under the action of centrifugal force, the moving rod moves away from the fixed sleeve. During this process, the moving rod stretches the second spring, which is stretched and deformed, storing elastic potential energy. Under the constraints of centrifugal force, the second spring, and the telescopic rod, the end of the moving rod can only extend forward a certain distance. In this state, when the stirring shaft drives the fixed sleeve and the moving rod to rotate, the side wall of the end of the moving rod will collide with the counterweight, causing the counterweight and scraper to vibrate back and forth. This shakes the liquid raw materials adhering to the counterweight and scraper into the reactor body, preventing the liquid raw materials from adhering to the scraper and counterweight and causing waste of resources.

[0027] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0028] Reference Figures 1-6 An automatic constant temperature and pressure reactor includes a reactor body 1. A feed pipe 2 is fixedly installed through the upper end face of the reactor body 1. A rotating ring 3 is rotatably installed at the inner top of the reactor body 1 and directly below the feed pipe 2. A scraper 4 is movably installed on the inner wall of the rotating ring 3. A counterweight 5 is fixed to the lower end face of the scraper 4. A stirring shaft 6 is rotatably installed between the inner top and inner bottom of the reactor body 1. A motor 7 for use with the stirring shaft 6 is fixed to the upper end face of the reactor body 1. A transmission assembly is installed between the stirring shaft 6 and the rotating ring 3. A material shaking assembly for use with the scraper 4 and the counterweight 5 is installed on the stirring shaft 6.

[0029] The reactor body 1 is also equipped with multiple other feed pipes, and multiple sensors are installed inside the reactor body 1 to coordinate and regulate the temperature and pressure inside the reactor body 1, thereby achieving the effect of automatic constant temperature and pressure.

[0030] Reference Figure 2 and Figure 3 During use, feed pipe 2 and other feed pipes are connected to multiple external material conveying pipes. When the external material conveying pipes inject liquid raw materials into the reactor body 1 through feed pipe 2, a certain amount of liquid raw materials will adhere to the inner wall of feed pipe 2 as it passes through it. After the initial feeding is completed, the valve on the corresponding material conveying pipe is closed. At this time, motor 7 drives stirring shaft 6 to rotate. Stirring shaft 6 stirs and mixes the raw materials and auxiliary materials inside the reactor body 1. During this process, stirring shaft 6 drives rotating ring 3 and scraper 4 to rotate through transmission components. When scraper 4 rotates with rotating ring 3, the side wall of scraper 4 will adhere to the inner wall of feed pipe 2, thereby scraping off the liquid raw materials adhering to feed pipe 2. Then, under the guidance of gravity and scraper 4, the liquid raw materials quickly drip down into the reactor body 1, avoiding the liquid raw materials adhering to the inner wall of feed pipe 2 and causing waste of chemical resources.

[0031] Reference Figure 2 and Figure 3 When the scraper 4 rotates with the rotating ring 3, the counterweight 5 will cause the scraper 4 to tilt and flip under the action of inertial force. This will guide the liquid material to move downward when the scraper 4 scrapes off the liquid material adhering to the feed pipe 2.

[0032] Reference Figure 5 A sliding groove 8 is provided inside the rotating ring 3. A sliding cylinder 9 is slidably arranged inside the sliding groove 8. A connecting column 10 is fixed on the side of the sliding cylinder 9 near the scraper 4. The connecting column 10 movably passes through the rotating ring 3. A reset component is provided between the sliding cylinder 9 and the sliding groove 8. The reset component includes a spring 11 fixed between the sliding cylinder 9 and the inner wall of the sliding groove 8.

[0033] Reference Figure 5In the initial state, spring 11 is in its normal position. At this time, there is a gap between scraper 4 and rotating ring 3, and the side wall of scraper 4 does not contact the inner wall of feed pipe 2. Then, motor 7 drives stirring shaft 6 to rotate rapidly. When rotating ring 3 rotates rapidly, scraper 4, connecting column 10, and sliding cylinder 9 will move towards rotating ring 3 under the action of centrifugal force. During this process, sliding cylinder 9 will squeeze spring 11, and spring 11 will be compressed and contracted, storing elastic potential energy. During this process, the side wall of scraper 4 will contact the inner wall of feed pipe 2, so that the rotating ring 3 can drive scraper 4 to move towards feed pipe 2. The liquid raw materials adhering to the inner wall are scraped off. After scraping for a period of time, the motor 7 slows down, so that the stirring shaft 6 returns to the normal stirring speed. At this time, the rotation speed of the rotating ring 3 decreases. At this time, the centrifugal force on the scraper 4, connecting column 10 and sliding cylinder 9 is small. At this time, the elastic potential energy stored in the spring 11 is released, pushing the scraper 4, connecting column 10 and sliding cylinder 9 back to the initial position. At this time, the side wall of the scraper 4 does not contact the inner wall of the feed pipe 2, so that the scraper 4 does not perform scraping work under the normal stirring operation of the stirring shaft 6, avoiding the scraper 4 from continuously contacting the inner wall of the feed pipe 2 and avoiding unnecessary wear on the scraper 4.

[0034] Reference Figure 2 , Figure 3 and Figure 4 The transmission assembly includes a gear ring 12 fixedly sleeved on the outer wall of the stirring shaft 6, and a gear ring 2 13 fixedly sleeved on the outer wall of the rotating ring 3. The gear ring 12 and the gear ring 2 13 are meshed together. When the motor 7 drives the stirring shaft 6 to rotate, the stirring shaft 6 drives the gear ring 12 to rotate. Since the gear ring 12 is meshed with the gear ring 2 13, the rotating gear ring 12 will drive the gear ring 2 13 and the rotating ring 3 to rotate, thereby driving the scraper 4 to rotate.

[0035] Reference Figure 3 and Figure 4 A T-shaped rotating ring 14 is fixed on the upper end face of the rotating ring 3. A T-shaped rotating groove is provided on the inner top of the reactor body 1 to cooperate with the T-shaped rotating ring 14. The T-shaped rotating ring 14 is rotatably connected to the T-shaped rotating groove. Through the cooperation of the T-shaped rotating ring 14 and the T-shaped rotating groove, the rotating ring 3 is rotatably connected to the inner top of the reactor body 1.

[0036] Reference Figure 2 and Figure 6The material shaking assembly includes a fixed sleeve 15 fixed to the outer wall of the stirring shaft 6. One end of the fixed sleeve 15 is provided with a sliding slot 16. A moving rod 17 is slidably arranged in the sliding slot 16. A reset component 2 is provided between the moving rod 17 and the sliding slot 16. The reset component 2 includes a telescopic rod 18 fixed between the moving rod 17 and the inner wall of the sliding slot 16. A spring 2 19 is also fixed between the moving rod 17 and the inner wall of the sliding slot 16. The spring 2 19 is movably sleeved on the outer wall of the telescopic rod 18.

[0037] In the initial stage, when the motor 7 drives the stirring shaft 6 to stir rapidly, the stirring shaft 6 drives the fixed sleeve 15 and the moving rod 17 to rotate together. At this time, the moving rod 17 moves away from the fixed sleeve 15 under the action of centrifugal force. During this process, the moving rod 17 stretches the second spring 19. The second spring 19 is stretched and deformed, storing elastic potential energy. Under the restriction of centrifugal force, the second spring 19 and the telescopic rod 18, the end of the moving rod 17 can only extend forward a certain distance. In this state, when the stirring shaft 6 drives the fixed sleeve 15 and the moving rod 17 to rotate, the side wall of the end of the moving rod 17 will collide with the counterweight 5, thereby causing the counterweight 5 and the scraper 4 to shake back and forth, thus shaking the liquid raw materials adhering to the counterweight 5 and the scraper 4 into the reactor body 1, avoiding the liquid raw materials from adhering to the scraper 4 and the counterweight 5, which would cause waste of resources.

[0038] When the motor 7 drives the stirring shaft 6 to resume normal stirring speed, the elastic potential energy stored in the second spring 19 is released, causing the second spring 19 to return to its initial state, thereby pulling the telescopic ends of the moving rod 17 and the telescopic rod 18 to their initial positions. At this time, the moving rod 17 will not collide with the counterweight 5 while rotating with the stirring shaft 6.

[0039] Reference Figure 2 and Figure 6 The end of the fixed sleeve 15 is fixedly fitted with a scraping sleeve 20, which is flared in shape.

[0040] When the motor 7 drives the stirring shaft 6 to stir rapidly, the stirring shaft 6 drives the fixed sleeve 15 and the moving rod 17 to rotate together. At this time, the moving rod 17 extends out of the scraping sleeve 20. When the end of the moving rod 17 collides with the counterweight 5, the liquid material on the counterweight 5 will also stick to the side wall of the end of the moving rod 17. When the motor 7 drives the stirring shaft 6 to resume normal stirring speed, the moving rod 17 returns to the fixed sleeve 15. During this process, the scraping sleeve 20 will scrape off the liquid material stuck to the outer side wall of the moving rod 17. This part of the liquid material is collected on the working end surface of the scraping sleeve 20 and then drips down, further avoiding waste of resources.

[0041] In use, the feed pipe 2 and other feed pipes are connected to multiple external material conveying pipes. When the external material conveying pipes inject liquid raw materials into the reactor body 1 through the feed pipe 2, a certain amount of liquid raw materials will adhere to the inner wall of the feed pipe 2 as it passes through it. After the initial feeding is completed, the valve on the corresponding material conveying pipe is closed. At this time, the motor 7 drives the stirring shaft 6 to rotate. The stirring shaft 6 stirs and mixes the raw materials and auxiliary materials inside the reactor body 1. During this process, the stirring shaft 6 drives the rotating ring 3 and the scraper 4 to rotate through the transmission component. When the scraper 4 rotates with the rotating ring 3, the side wall of the scraper 4 will stick to the inner wall of the feed pipe 2, thereby scraping off the liquid raw materials adhering to the feed pipe 2. Then, under the guidance of gravity and the scraper 4, the liquid raw materials quickly drip down into the reactor body 1, avoiding the liquid raw materials from adhering to the inner wall of the feed pipe 2 and causing waste of resources.

[0042] Initially, spring 11 is in its normal state, and there is a gap between scraper 4 and rotating ring 3. At this time, the side wall of scraper 4 is not in contact with the inner wall of feed pipe 2. Then, motor 7 drives stirring shaft 6 to rotate rapidly. When rotating ring 3 rotates rapidly, scraper 4, connecting column 10, and sliding cylinder 9 will move towards rotating ring 3 under the action of centrifugal force. During this process, sliding cylinder 9 will squeeze spring 11, causing spring 11 to be compressed and store elastic potential energy. During this process, the side wall of scraper 4 will contact the inner wall of feed pipe 2, so that rotating ring 3 can drive scraper 4 to move towards feed pipe 2. The liquid raw materials adhering to the inner wall are scraped off. After scraping for a period of time, the motor 7 slows down, so that the stirring shaft 6 returns to the normal stirring speed. At this time, the rotation speed of the rotating ring 3 decreases. At this time, the centrifugal force on the scraper 4, connecting column 10 and sliding cylinder 9 is small. At this time, the elastic potential energy stored in the spring 11 is released, pushing the scraper 4, connecting column 10 and sliding cylinder 9 back to the initial position. At this time, the side wall of the scraper 4 does not contact the inner wall of the feed pipe 2, so that the scraper 4 does not perform scraping work under the normal stirring operation of the stirring shaft 6, avoiding the scraper 4 from continuously contacting the inner wall of the feed pipe 2, and avoiding unnecessary wear on the scraper 4.

[0043] In the initial stage, when the motor 7 drives the stirring shaft 6 to stir rapidly, the stirring shaft 6 drives the fixed sleeve 15 and the moving rod 17 to rotate together. At this time, the moving rod 17 moves away from the fixed sleeve 15 under the action of centrifugal force. During this process, the moving rod 17 stretches the second spring 19. The second spring 19 is stretched and deformed, storing elastic potential energy. Under the restriction of centrifugal force, the second spring 19 and the telescopic rod 18, the end of the moving rod 17 can only extend forward a certain distance. In this state, when the stirring shaft 6 drives the fixed sleeve 15 and the moving rod 17 to rotate, the side wall of the end of the moving rod 17 will collide with the counterweight 5, thereby causing the counterweight 5 and the scraper 4 to shake back and forth, thereby shaking the liquid raw materials adhering to the counterweight 5 and the scraper 4 into the reactor body 1, avoiding the liquid raw materials from adhering to the scraper 4 and the counterweight 5, causing waste of resources.

[0044] When the motor 7 drives the stirring shaft 6 to stir rapidly, the stirring shaft 6 drives the fixed sleeve 15 and the moving rod 17 to rotate together. At this time, the moving rod 17 extends out of the scraping sleeve 20. When the end of the moving rod 17 collides with the counterweight 5, the liquid material on the counterweight 5 will also stick to the side wall of the end of the moving rod 17. When the motor 7 drives the stirring shaft 6 to resume normal stirring speed, the moving rod 17 returns to the fixed sleeve 15. During this process, the scraping sleeve 20 will scrape off the liquid material stuck to the outer side wall of the moving rod 17. This part of the liquid material is collected on the working end surface of the scraping sleeve 20 and then drips down, further avoiding waste of resources.
