Description

Technical Field

[0001] The utility model belongs to the technical field of PVC heat stabilizer production equipment, and specifically relates to a PVC heat stabilizer production cooling device. Background Art

[0002] In the production process of PVC heat stabilizer in the prior art, the raw materials need to go through the processes of stirring, filter pressing, drying and crushing to obtain the finished product; and during stirring, since the raw materials contain a multi-component mixed material of various organic materials, inorganic materials and even nano materials, a large amount of heat will be generated during stirring.

[0003] The prior art discloses a PVC heat stabilizer production cooling device with a patent announcement number of CN212576235U. The patent includes a reactor, in which a through main shaft is installed. The upper and lower ends of the main shaft extend out of the reactor, and the upper end of the main shaft is provided with a driven gear, and a driving gear is correspondingly meshed and installed on the outer side of the driven gear. A driving motor is correspondingly installed on the driving gear, and the main shaft is driven to rotate in the reactor by the driving motor. In this device, the cold water channel is set inside the main shaft and the stirring shaft. The cooling water flows through the inside of the main shaft and the S-shaped stirring shaft, and flows when the main shaft rotates to drive the S-shaped stirring shaft to stir. In this way, as the S-shaped stirring shaft rotates, the cooling range of the cooling water is very large, which can cover the core area in the reactor, and the position is always changing, not fixed, so the cooling effect is very good, but there are still the following deficiencies in actual use: from a practical point of view, the device can only cool the material by stirring. Since the material cannot be circulated during the stirring process, it is difficult to cool the material quickly. Moreover, under long-term stirring, since the material is always stirred according to a certain rule, the heat transfer in the same area can easily cause the cooling temperature to be kept within a range from beginning to end, thereby reducing the cooling efficiency and increasing the cooling time.

[0004] Therefore, a PVC heat stabilizer production cooling device is needed to solve the problem in the prior art that the material cannot be circulated, which makes it difficult to cool the material quickly and the cooling temperature can only be maintained within a range from beginning to end during the material stirring process.

[0027] When in use, the cooling water in the cold water tank 401 is circulated and transported in the cooling pipe 403 through the delivery pipe 402 by running the pump, so that the cooling pipe 403 cools the circulation barrel 501, thereby realizing the cooling work of the material in cooperation with the circulation mechanism 5.

[0028] According to the above working process, it can be known that: by setting the cooling device 4 in conjunction with the circulation mechanism 5, when cooling the material in the reactor 1, the material can be circulated, which speeds up the process of heat dissipation of the material, and then the cooling efficiency of the material can be improved through the cooling device.

Since the chamber is connected with the inside of the circulation barrel 501 through the guide port 504 and the connecting port 505, the airflow forms a cycle, so that the material is circulated again in the chamber through the connecting port 505 and transported to the circulation barrel 501. In the process of transportation in the chamber, due to the set spoiler groove 507, the airflow forms a certain cyclone at the spoiler groove 507, so that the material can rotate in the cyclone, and then the cooling effect on the material is further improved through the circulation barrel 501, thereby improving the cooling efficiency.
