Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch production, and more specifically, to a masterbatch cooling device. Background Art

[0002] Masterbatch refers to the process of plastic processing and molding. For the convenience of operation, various additives, fillers and a small amount of carrier resin are mixed and kneaded first. After being extruded into masterbatch by an extruder, the masterbatch is immersed in the cooling water of the cooling device for water cooling. After the masterbatch is cooled, it is sent out of the cooling device for drying. After the masterbatch is dried, it is cut into pellets by a pelletizing device to obtain granular materials.

[0003] The current cooling device is a water cooling device, and the cooling water tank is relatively long. Although the mother bar is conveyed in the cooling water to ensure the cooling effect of the mother bar, when the mother bar is conveyed out of the cooling device, its surface will carry a large amount of moisture, which is not conducive to the drying operation of the mother bar and reduces the production efficiency of the masterbatch. Therefore, it is urgently needed to improve this. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and provide a mother bar cooling device, which realizes water cooling and air cooling of the mother bar by setting a water cooling bin, a water blowing bin and an air cooling bin, which not only effectively ensures the cooling effect of the mother bar, but also can maintain the drying effect of the mother bar after cooling, thereby improving the production efficiency of masterbatch.

It is used to shape and solidify the mother bar 100 to facilitate the transmission of the mother bar 100. The mother bar 100 is transmitted into the water blowing bin 2 through the first transmission roller 7. The upper and lower surfaces of the mother bar 100 are blown with water by the blow gun 4 to blow off the water droplets on the surface of the mother bar 100 for pre-drying. At the same time, the blown wind can further cool the mother bar 100. The mother bar 100 after water blowing is transmitted to the air-cooling bin 3 through the second transmission roller 8. The fan 5 arranged along the length direction of the air-cooling bin 3 can not only cool the mother bar 100, but also further dry the mother bar 100, so that the transmitted mother bar 100 does not need to be dried again, and can be directly pelletized, which greatly improves the production efficiency of the masterbatch.

[0019] A partition 6 is fixed between the water-cooling bin 1 and the water-blowing bin 2, and the partition 6 includes a transfer port 61 and a through hole 62. The mother bar 100 passes through the transfer port 61, and the through hole 62 is located at the bottom of the partition 6. The bottom of the water-blowing bin 2 is higher than the bottom of the water-cooling bin 1, and the bottom of the water-blowing bin 2 is inclined downward toward the water-cooling bin 1. The through hole 62 is located at the lowest point of the bottom of the water-blowing bin 2, and the position of the through hole 62 is higher than the liquid level in the water-cooling bin 1. By setting the partition 6, the torrent wind blown out by the blow gun 4 can be effectively blocked from affecting the coolant in the water-cooling bin 1. By setting the water-blowing bin 2 with an inclined bottom, the water droplets blown off can be easily returned to the water-cooling bin 1 from the through hole 62.

[0020] The present embodiment also includes a water circulation mechanism 9, which includes a water outlet pipe 91, a water pump 93 and a water inlet pipe 95. The inlet end of the water outlet pipe 91 is connected to the bottom of the water cooling warehouse 1 and the outlet end is connected to the inlet of the water pump 93. The inlet end of the water inlet pipe 95 is connected to the outlet of the water pump 93. A water inlet 11 is provided on the side of the water cooling warehouse 1. The other end of the water inlet pipe 95 is connected to the water inlet 11. Specifically, the water circulation mechanism 9 includes a coil 92, and the coil 92 is distributed in an S shape. The coil 92 is located in the air cooling warehouse 3, and the fan 5 is directly opposite to the coil 92. The outlet end of the water outlet pipe 91 is connected to the inlet of the coil 92, and the outlet of the coil 92 is connected to the inlet of the water pump 93 through a connecting pipe 94.

At this time, the water pump 93 can be turned on to pass the cooling water in the water-cooling bin 1 through the water outlet pipe 91, the coil 92, the connecting pipe 94, the water pump 93, the water inlet pipe 95, and the water inlet 11 in sequence, and finally re-enter the water-cooling bin 1 to realize the circulation function of the cooling water. When the cooling water passes through the coil 92, the cooling water in the coil 92 can be cooled by the fan 5. The cooled cooling water re-enters the water-cooling bin 1 through the water pump 93, thereby effectively ensuring the pre-cooling effect of the water-cooling bin 1.
