Description

Technical Field

[0001] This utility model relates to the field of PVC stabilizer production, and in particular to a PVC stabilizer reaction vessel capable of temperature regulation. Background Technology

[0002] PVC composite stabilizers are additive mixtures that can improve the thermal stability of PVC polymers. They can capture HCl released by PVC resin with autocatalytic activity or react with unstable structures generated by PVC resin, thereby interrupting the degradation chain reaction and achieving the purpose of stabilizing PVC.

[0003] In the production of PVC composite stabilizers, mixing is also required to ensure that the components of the PVC composite stabilizer are fully and uniformly dispersed in the PVC resin. However, there is no good temperature control during the mixing of PVC composite stabilizers. If the temperature is too low, the PVC material may be plasticized unevenly, affecting its physical properties; while if the temperature is too high, the PVC material may consume too much stabilizer in the mixing tank, easily degrade, or even cause agglomeration and coagulation. Utility Model Content

[0004] The main objective of this invention is to provide a PVC stabilizer reactor capable of temperature regulation, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A temperature-regulating PVC stabilizer reactor includes a mounting base and a water tank. A controller is fixedly mounted on the upper front end of the mounting base, and a mounting sleeve is fixedly mounted on the upper right end of the mounting base. A mixing vessel is fixedly mounted through the upper end of the mounting sleeve. Mixing devices are fixedly mounted on the upper left and upper front ends of the mixing vessel. A heating device is fixedly mounted on the lower end of the mixing vessel, and a water cooling device is fixedly mounted on the front end of the water tank.

[0007] Preferably, the mixing device includes a servo motor and a first pulley. A second pulley is fixedly mounted on the output end of the servo motor. A transmission belt is mounted on the outer surfaces of both the first and second pulleys. A stirring frame is fixedly mounted on the lower end of both the first and second pulleys. Both stirring frames are rotatably mounted inside the mixing vessel. A mounting bracket is fixedly mounted on the right end of the servo motor. A temperature sensor is fixedly mounted on the lower end of the mounting bracket, located inside the mixing vessel. The servo motor is fixedly mounted on the upper right side of the mixing vessel via the mounting bracket. The servo motor drives the second pulley, which in turn drives the first pulley via the transmission belt, causing the stirring frames at the lower ends of the two pulleys to rotate within the mixing vessel. Furthermore, the mixing device has two units, and the four stirring frames are arranged in a rectangular row within the mixing vessel, with each pair of stirring frames rotating in opposite directions. Therefore, the device can thoroughly agitate the raw materials within the mixing vessel.

[0008] Preferably, the water cooling device includes a water pump, a water delivery pipe installed at the front end of the water pump, a return pipe fixedly installed at the upper end of the water tank, and a circulation pipe fixedly installed at the front ends of the water delivery pipe and the return pipe. The water pump is fixedly installed at the front end of the water tank. A cooling plate is provided on the lower inner wall of the water tank, and the cooling plate is electrically connected to the controller. The water pump draws cold water from the water tank and delivers it to the circulation pipe through the water delivery pipe, and finally returns it to the water tank through the return pipe. This process is repeated. When the cold water passes through the circulation pipe, it carries away the heat from the mixing vessel, thereby cooling the mixing vessel.

[0009] Preferably, the heating device includes a heater and a heat-conducting base. A heating tube is installed at the left end of the heater and is inserted into the heat-conducting base. The heat-conducting base is fixedly installed at the lower end of the mixing vessel, and the heater is fixedly installed at the lower right end of the mounting sleeve. The controller is electrically connected to the servo motor, temperature sensor, water pump, and heater. The heater drives the heating tube to heat the heat-conducting base, which then transfers heat to the mixing vessel for heating treatment.

[0010] Preferably, the four stirring racks are arranged in a rectangular row inside the mixing vessel.

[0011] Preferably, the circulation pipe is inserted and fixedly installed inside the mounting sleeve, and the circulation pipe is in contact with the outer surface of the mixing vessel.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The servo motor on the mixing device drives the second pulley, which in turn drives the first pulley via a transmission belt. This causes the stirring racks at the lower ends of the two pulleys to rotate inside the mixing vessel. In addition, there are two mixing devices, and the four stirring racks are arranged in a rectangular row inside the mixing vessel. The four stirring racks rotate in opposite directions to each other. Therefore, the device can fully agitate the raw materials in the mixing vessel, thus improving the mixing effect.

[0014] 2. The temperature sensor transmits the temperature inside the mixing vessel to the controller for display. When the temperature is too low, the heater drives the heating tube to heat the heat-conducting seat, which then transfers heat to the mixing vessel for heating. When the temperature is too high, the water pump draws cold water from the water tank and delivers it to the circulation pipe through the water supply pipe. Finally, the water flows back to the water tank through the return pipe. This process is repeated. When the cold water passes through the circulation pipe, it carries away the heat from the mixing vessel, thereby cooling the mixing vessel. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-4 As shown, a temperature-regulating PVC stabilizer reactor includes a mounting base 1 and a water tank 5. A controller 8 is fixedly installed on the upper front end of the mounting base 1, and a mounting sleeve 7 is fixedly installed on the upper right end of the mounting base 1. A mixing vessel 6 is fixedly installed through the upper end of the mounting sleeve 7. A mixing device 2 is fixedly installed on the upper left and upper front ends of the mixing vessel 6. A heating device 4 is fixedly installed on the lower end of the mixing vessel 6, and a water cooling device 3 is fixedly installed on the front end of the water tank 5.

[0024] The mixing device 2 includes a servo motor 20 and a first pulley 21. A second pulley 22 is fixedly mounted on the output end of the servo motor 20. A transmission belt 23 is mounted on the outer surfaces of both pulleys 21 and 22. A stirring frame 24 is fixedly mounted on the lower end of both pulleys 21 and 22. Both stirring frames 24 are rotatably mounted inside the mixing vessel 6. A mounting bracket 25 is fixedly mounted on the right end of the servo motor 20. A temperature sensor 26 is fixedly mounted on the lower end of the mounting bracket 25. The temperature sensor 26 is located inside the mixing vessel 6. The servo motor 20 is fixedly mounted on the upper right side of the mixing vessel 6 via the mounting bracket 25. The four stirring frames 24 are arranged in a rectangular row inside the mixing vessel 6. The servo motor 20 drives the second pulley 22, which in turn drives the first pulley 21 via the transmission belt 23. This causes the stirring racks 24 at the lower ends of the two pulleys to rotate inside the mixing vessel 6. In addition, there are two mixing devices 2, and the four stirring racks 24 are arranged in a rectangular row inside the mixing vessel 6. The four stirring racks 24 rotate in opposite directions to each other. Therefore, the device can fully agitate the raw materials inside the mixing vessel 6.

[0025] The water cooling device 3 includes a water pump 30, with a water supply pipe 31 installed at the front end of the water pump 30. A return pipe 32 is fixedly installed at the upper end of the water tank 5. A circulation pipe 33 is fixedly installed at the front ends of the water supply pipe 31 and the return pipe 32. The water pump 30 is fixedly installed at the front end of the water tank 5. The circulation pipe 33 is inserted and fixedly installed inside the mounting sleeve 7, and the circulation pipe 33 is in contact with the outer surface of the mixing vessel 6. A cooling plate is provided on the lower inner wall of the water tank 5, and the cooling plate is electrically connected to the controller 8. The water pump 30 draws cold water from the water tank 5 and delivers it to the circulation pipe 33 through the water supply pipe 31. Finally, it flows back to the water tank 5 through the return pipe 32. This process is repeated. When the cold water passes through the circulation pipe 33, it carries away the heat from the mixing vessel 6, thereby cooling the mixing vessel 6.

[0026] The heating device 4 includes a heater 40 and a heat-conducting seat 41. A heating tube 42 is installed at the left end of the heater 40 and is inserted into the heat-conducting seat 41. The heat-conducting seat 41 is fixedly installed at the lower end of the mixing vessel 6, and the heater 40 is fixedly installed at the lower right end of the mounting sleeve 7. The controller 8 is electrically connected to the servo motor 20, the temperature sensor 26, the water pump 30, and the heater 40. Before use, the controller 8 can be connected to an external power source. The heater 40 drives the heating tube 42 to heat the heat-conducting seat 41, thereby transferring heat to the mixing vessel 6 for heating treatment.

[0027] It should be noted that this utility model is a PVC stabilizer reactor capable of temperature regulation. A servo motor 20 on the mixing device 2 drives a second pulley 22, which in turn drives a first pulley 21 via a transmission belt 23. This causes the stirring racks 24 at the lower ends of the two pulleys to rotate within the mixing vessel 6. Furthermore, there are two mixing devices 2, and the four stirring racks 24 are arranged in a rectangular row within the mixing vessel 6, with each pair of stirring racks rotating in opposite directions. Therefore, the device can thoroughly agitate the raw materials within the mixing vessel 6, improving the mixing efficiency. The mixing vessel 6 achieves a combined effect, and the temperature sensor 26 transmits the temperature inside the mixing vessel 6 to the controller 8 for display. When the temperature is too low, the heater 40 drives the heating tube 42 to heat the heat conduction seat 41, which then transfers heat to the mixing vessel 6 for heating. When the temperature is too high, the water pump 30 draws cold water from the water tank 5 and delivers it to the circulation pipe 33 through the water supply pipe 31. Finally, the water flows back to the water tank 5 through the return pipe 32. This process is repeated. When the cold water passes through the circulation pipe 33, it carries away the heat from the mixing vessel 6, thereby cooling the mixing vessel 6.
