Abstract
Description
Technical Field
[0001] This application relates to the field of reaction vessels, and in particular to a high-efficiency discharge reaction vessel. Background Technology
[0002] A reaction vessel is a container used for physical or chemical reactions. Through structural design and parameter configuration, it can achieve the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process, and has been widely used in the plastics industry.
[0003] When a typical discharge valve is installed, it is kept at a distance from the discharge port of the reactor. This means that when raw materials are added to the reactor, some of the raw materials will enter this space. The raw materials in this space are difficult to stir during the reaction, which can easily cause blockage of the discharge port. Utility Model Content
[0004] In order to make the material discharge from the reactor more efficient, this application provides a high-efficiency discharge reactor.
[0005] The high-efficiency discharge reactor provided in this application adopts the following technical solution: A high-efficiency discharge reactor includes a reactor body, a discharge pipe connected to the lower end of the reactor body, a discharge valve for controlling the opening and closing of the discharge pipe, a rotating shaft coaxially connected to the reactor body, a stirring paddle provided on the outer wall of the rotating shaft, a vertically downward-oriented driving cylinder provided at the upper end of the reactor body, and a sealing plate for sealing the discharge port of the reactor body provided at the lower end of the piston rod of the driving cylinder.
[0006] By adopting the above technical solution, before adding materials into the reactor, the driving cylinder drives the sealing plate to seal the discharge pipe of the reactor body, so that when materials are added, some materials will not fall into the discharge pipe, allowing the materials to melt more fully in the reactor body. After the reaction is completed, the driving cylinder lifts the sealing plate upward, so that the sealing plate no longer seals the discharge pipe, facilitating the flow of materials. Compared with traditional reactors, where some materials will block the discharge pipe, making discharge more difficult, this reactor discharges materials more efficiently.
[0007] Optionally, the rotating shaft is a hollow circular tube, and the lower end of the piston rod of the driving cylinder is coaxially connected to a vertical connecting rod. The connecting rod is coaxially sleeved inside the rotating shaft, and the sealing plate is located at the lower end of the connecting rod, directly below the connecting rod.
[0008] By adopting the above technical solution, the drive cylinder moves the sealing plate up and down through the connecting rod. The connecting rod is sleeved with the rotating shaft, which reduces the occurrence of jamming.
[0009] Optionally, the lower end of the rotating shaft is provided with a sealing ring for sealing the gap between the rotating shaft and the connecting rod.
[0010] By adopting the above technical solution, the sealing ring can reduce the occurrence of material entering the rotating shaft.
[0011] Optionally, a first gear is fitted onto the upper end of the rotating shaft, a drive motor is provided above the vessel body, and a second gear is fitted onto the transmission rod of the drive motor, with the first gear and the second gear meshing together.
[0012] By adopting the above technical solution, the drive motor drives the second gear to rotate, the second gear meshes with the first gear, thereby driving the first gear to rotate, and the first gear rotates, driving the shaft to rotate.
[0013] Optionally, the upper end of the vessel body is provided with an air inlet pipe, and an air pump is installed in the air inlet pipe.
[0014] By adopting the above technical solution, the reactor is pressurized by an air pump during discharge, making the discharge of materials from the reactor more efficient.
[0015] Optionally, the vessel body is provided with a horizontal filter screen, which is located vertically between the air inlet pipe and the stirring paddle.
[0016] By adopting the above technical solution, the material in the reactor is prone to splashing during stirring, which can cause blockage of the air inlet pipe. The filter screen can block the splashed material and reduce the occurrence of blockage of the air inlet pipe.
[0017] Optionally, the inner wall of the reactor is provided with a horizontal circular frame, and two horizontal semi-circular frames are rotatably connected inside the circular frame. The area of the circle formed by the combination of the two semi-circular frames is the same as that of the circular frame, and the filter screen is disposed inside the semi-circular frames.
[0018] By adopting the above technical solution, when adding raw materials into the reactor, the operator rotates the two semi-circular frames to an overlapping state, so that the raw materials can be smoothly added into the reactor. During the reaction, the operator rotates the semi-circular frames so that the two semi-circular frames combine to form a circular frame, blocking splashed materials.
[0019] Optionally, the diameter sides of the two semicircular frames are connected to each other by snap fasteners.
[0020] By adopting the above technical solution, the two semi-circular frames are fixed by buckles, reducing the occurrence of relative rotation of the two semi-circular frames due to vibration during material mixing.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] Before adding materials into the reactor, the drive cylinder drives the sealing plate to seal the discharge pipe of the reactor body, so that some materials will not fall into the discharge pipe when materials are added, allowing the materials to melt more fully in the reactor body. After the reaction is completed, the drive cylinder lifts the sealing plate upward, so that the sealing plate no longer seals the discharge pipe, facilitating the flow of materials. Compared with traditional reactors, where some materials will block the discharge pipe and make discharge more difficult, this reactor has a more efficient discharge rate.
[0023] The material inside the reactor is prone to splashing during stirring, which can cause blockage of the air inlet pipe. The filter screen is designed to block the splashed material and reduce the occurrence of blockage in the air inlet pipe. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0029] This application discloses a high-efficiency discharge reactor. (Refer to...) Figure 1 , Figure 2 as well as Figure 3A high-efficiency discharge reactor includes a reactor body 1. A discharge pipe 11 is coaxially mounted on the lower end of the reactor body 1. A discharge valve 12 for controlling the opening and closing of the discharge pipe 11 is installed on the discharge pipe 11. A vertically downward-oriented drive cylinder 2 is fixed to the upper end of the reactor body 1 by a frame. The lower end of the piston rod of the drive cylinder 2 is coaxially connected to a vertically downward-oriented connecting rod 21. A sealing plate 22 for sealing the discharge port of the reactor body 1 is fixedly connected to the lower end of the connecting rod 21. Typically, the discharge valve 12 is installed at a distance from the discharge port of the reactor, so that… When raw materials are added to the reactor body 1, some of the raw materials will enter the space. The raw materials in this space are difficult to stir during the reaction, which can easily cause blockage of the discharge port. Before adding raw materials, the reactor body 1 is sealed by the drive cylinder 2 driving the sealing plate 22 to reduce the accumulation of raw materials in the discharge pipe 11. When it is necessary to release the material, the drive cylinder 2 lifts the sealing plate 22 upward so that the sealing plate 22 no longer blocks the discharge port. The material is discharged from the unblocked discharge pipe 11 more efficiently.
[0030] Reference Figure 1 , Figure 2 as well as Figure 3 A drive motor 3 is installed at the upper end of the vessel body 1. A second gear 32 is sleeved on the transmission rod of the drive motor 3. A rotating shaft 33 is coaxially rotatably connected inside the vessel body 1. The rotating shaft 33 is a hollow round tube and is coaxially sleeved on the outside of the connecting rod 21. A stirring paddle 35 is installed on the outer wall of the rotating shaft 33. The upper end of the rotating shaft 33 extends out of the vessel body 1. A first gear 31 is sleeved on the upper end of the rotating shaft 33. The first gear 31 and the second gear 32 are meshed. When the drive motor 3 is working, it drives the stirring paddle 35 to stir the material inside the vessel body 1 through the transmission of the first gear 31 and the second gear 32.
[0031] Reference Figure 1 , Figure 2 as well as Figure 3 An air inlet pipe 41 is installed at the upper end of the reactor body 1. An air pump 4 is installed in the air inlet pipe 41 to pressurize the reactor. When the reactor discharges material, the air pump 4 pressurizes the reactor, making the material discharge more efficient. A horizontal circular frame 5 is installed inside the reactor. The circular frame 5 is located vertically between the stirring paddle 35 and the air inlet pipe 41. Two horizontal semi-circular frames 51 are rotatably connected inside the circular frame 5. The area of the circle formed by the combination of the two semi-circular frames 51 is equal to that of the circular frame 5. A filter screen 53 is installed inside each of the two semi-circular frames 51. The two semi-circular frames 51 are connected and fixed to each other by a buckle 52. When adding raw materials into the reactor, the operator rotates the two semi-circular frames 51 to an overlapping state so that the raw materials can be smoothly added into the reactor. During the reaction, the operator rotates the semi-circular frames 51 so that the two semi-circular frames 51 combine to form a circular frame 5 to block splashed materials.
[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
