A high-efficiency glass-lined reactor with eccentric stirring shaft

Abstract

This utility model discloses a high-efficiency glass-lined reaction vessel with an eccentric stirring shaft. It includes a vessel body, with two fixed shafts rotatably connected to the top of the vessel body and extending into the vessel body. An eccentric stirring mechanism is installed inside the vessel body, comprising a connecting plate, an eccentric shaft, a stirring rod motor, and a support frame. The support frame is fixedly installed on the top of the vessel body, and the motor is fixedly installed on the top of the support frame. The output shaft of the motor is fixedly connected to one of the fixed shafts. The connecting plate is fixedly installed at the bottom of the two fixed shafts inside the vessel body. Rotation of the fixed shaft in the eccentric stirring mechanism drives the connecting plate to rotate, which in turn drives the eccentric shaft to rotate, thereby driving multiple stirring rods to rotate and stirring the materials inside the vessel. The eccentric shaft generates an asymmetric flow field during eccentric stirring, reducing the mixing dead zone, thus accelerating the reaction rate and improving efficiency.

Description

Technical Field

[0001] This utility model relates to the field of glass-lined reaction vessel technology, specifically a high-efficiency glass-lined reaction vessel with an eccentric stirring shaft. Background Technology

[0002] Glass-lined reaction vessels are made by lining the inner surface of a steel container with high-silica glass, which is then firmly bonded to the metal surface by high-temperature firing. They are mainly used in industries such as petrochemicals, rubber, pesticides, dyes, and pharmaceuticals to complete processes such as sulfonation, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation, as well as many other processes for organic dyes and intermediates.

[0003] Currently, when glass-lined tanks are in operation, the materials inside the tank are mainly stirred and reacted directly by a stirring shaft. However, the stirring shaft is generally located in the center of the tank. This fixed stirring position may create dead zones in the stirring reaction, thereby reducing the stirring reaction rate. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a high-efficiency glass-lined reaction vessel with an eccentric stirring shaft, thereby resolving the issues raised in the background section.

[0005] To achieve the above objectives, this utility model proposes a high-efficiency glass-lined reaction vessel with an eccentric stirring shaft, comprising a vessel body, two fixed shafts for filling and extending into the vessel body being rotatably connected to the top of the vessel body, and a rotating shaft penetrating and extending into the vessel body being rotatably connected to the middle position of the top of the vessel body.

[0006] The tank is equipped with an eccentric stirring mechanism, which includes a connecting plate, an eccentric shaft, a stirring rod motor, and a support frame. The support frame is fixedly installed on the top of the tank, and a motor is fixedly installed on the top of the support frame. The output shaft of the motor is fixedly connected to one of the fixed shafts. The two fixed shafts are fixedly installed with connecting plates at the bottom of the tank. The bottom of each of the two connecting plates is fixedly installed with an eccentric shaft, and multiple stirring rods are fixedly installed on the outer ring of each of the two eccentric shafts.

[0007] In one example, the rotating shaft is located on the outer ring of the tank body and has two sprocket sets installed thereon, with the other end of each sprocket set connected to a fixed shaft.

[0008] In one example, the rotating shaft is located on the outer ring of the tank body and two fixing plates are fixedly installed, and scrapers are fixedly installed on the sides of the two fixing plates that are far apart from each other.

[0009] In one example, an inlet pipe and an exhaust pipe are fixedly installed on the other side of the top of the tank.

[0010] In one example, a discharge pipe is fixedly installed at the bottom center of the tank, and a solenoid valve is installed on the outer ring of the discharge pipe.

[0011] In one example, a support leg is fixedly installed at the bottom of the tank.

[0012] The high-efficiency glass-lined reaction vessel with an eccentric stirring shaft proposed in this utility model can bring the following beneficial effects:

[0013] 1. This high-efficiency glass-lined reaction vessel with an eccentric stirring shaft rotates by rotating a fixed shaft in the eccentric stirring mechanism, which in turn drives a connecting plate to rotate and the eccentric shaft to rotate. This, in turn, drives multiple stirring rods to rotate and stirs the materials inside the vessel. By setting the eccentric shaft, an asymmetric flow field is generated during eccentric stirring, reducing the mixing dead zone, thereby accelerating the reaction rate and improving its efficiency.

[0014] 2. This high-efficiency glass-lined reaction vessel with an eccentric stirring shaft rotates a fixed plate, which in turn rotates a scraper. The scraper can scrape off some material adhering to the inner wall of the vessel, thereby improving the stirring and reaction of the material inside the vessel and increasing the reaction rate.

[0020] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0021] like Figures 1-3As shown, an embodiment of this utility model proposes a high-efficiency glass-lined reaction vessel with an eccentric stirring shaft, including a vessel body 1. The top of the vessel body 1 is rotatably connected to two fixed shafts 6 that are filled and extend into the vessel body 1, and the top middle position of the vessel body 1 is rotatably connected to a rotating shaft 2 that passes through and extends into the vessel body 1.

[0022] The tank 1 is equipped with an eccentric stirring mechanism, which includes a connecting plate 7, an eccentric shaft 8, stirring rods 9, a motor 10, and a support frame 11. The support frame 11 is fixedly installed on the top of the tank 1, and the motor 10 is fixedly installed on the top of the support frame 11. The output shaft of the motor 10 is fixedly connected to one of the fixed shafts 6. The two fixed shafts 6 are fixedly installed at the bottom of the tank 1 with connecting plates 7. The bottom of the two connecting plates 7 is fixedly installed with eccentric shafts 8, and multiple stirring rods 9 are fixedly installed on the outer ring of the two eccentric shafts 8.

[0023] Specifically, two sprocket sets 5 are installed on the outer ring of the rotating shaft 2 outside the tank body 1. The other end of each sprocket set 5 is connected to the fixed shaft 6, and the sprocket sets 5 respectively transmit power between the fixed shaft 6 and the outer ring of the rotating shaft 2.

[0024] Specifically, the rotating shaft 2 is located on the outer ring of the tank 1 and two fixing plates 3 are fixedly installed. Scrapers 4 are fixedly installed on the side of the two fixing plates 3 that are far apart from each other. The scrapers 4 are fixed by the fixing plates 3. The scrapers 4 stir and react the material in the tank 1 and scrape off some residual material on its inner wall.

[0025] Specifically, a feed pipe 16 and an exhaust pipe 12 are fixedly installed on the other side of the top of the tank 1. The feed pipe 16 is used for feeding, and the exhaust pipe 12 is used to exhaust the gas generated during stirring.

[0026] Specifically, a discharge pipe 13 is fixedly installed at the middle of the bottom of the tank 1, and a solenoid valve 14 is installed on the outer ring of the discharge pipe 13. The material mixed in the tank 1 is discharged through the discharge pipe 13, and the solenoid valve 14 controls the discharge pipe 13.

[0027] Specifically, a support leg 15 is fixedly installed at the bottom of the tank body 1 to provide fixed support for the tank body 1.

[0028] Working principle: Material is poured into tank 1 through feed pipe 16. Then, motor 10 is started to drive one of the fixed shafts 6 to rotate, which in turn drives the rotating shaft 2 through one of the sprocket sets 5, and the other fixed shaft 6 through another sprocket set 5. This drives the two connecting plates 7 to rotate, causing the eccentric shaft 8 to rotate, which in turn drives the stirring rod 9 to rotate, thereby stirring the material in tank 1. At the same time, the rotation of the rotating shaft 2 drives the fixed plate 3 to rotate, which in turn drives the scraper 4 to make a circular motion, which can scrape off some of the adhering material, so that the material in tank 1 can be stirred and reacted better. After the stirring reaction is completed, the discharge pipe 13 is opened through the solenoid valve 14, and the stirred material is discharged through the discharge pipe 13.
