Description

Technical Field

[0001] The utility model relates to the technical field of air-cooling devices, in particular to an air-cooling device for a granulator. Background Art

[0002] The air-cooling device of a granulator is a device for heat dissipation, and its main function is to help dissipate the heat generated inside the equipment to ensure the normal operation of the equipment. In a granulator, granular materials are pressed into granular form through a series of technological processes, and heat will be generated during this process. The air-cooling device is one of the key components for dissipating this heat. When the granular materials pass through processes such as pressing in the granulator, a certain degree of heat accumulation will occur. If this heat cannot be dissipated in time, it will affect the normal operation of the equipment or even cause failures. When the materials in the pellet extruder are transported in the screw extrusion tube body, a large amount of heat will be generated. At this time, the air-cooling device needs to blow cool air into the tube body to accelerate the heat dissipation, so as to maintain the stable operating temperature of the equipment;

[0003] An air-cooling device for a screw extrusion granulator shown in the publication number CN213137759U includes an air-cooling sleeve mechanism, a clamping and supporting mechanism, and a blowing mechanism. The clamping and supporting mechanism is movably installed at one end of the air-cooling sleeve mechanism, and the blowing mechanism is fixedly installed at the other end of the air-cooling sleeve mechanism. The air-cooling sleeve mechanism is provided with a sleeve body, a first flange connection head, a reinforcing pipe, and an air inlet flange head. One end of the sleeve body is fixedly welded with the first flange connection head, the reinforcing pipe is fixedly welded at the other end of the sleeve body, and the air inlet flange head is fixedly welded on the side of the end of the sleeve body where the first flange connection head is provided and is communicated with the sleeve body.

[0004] In the above device, although the sleeve body wraps the entire extrusion tube section, so that the air blown in by the blowing mechanism takes the heat generated by the materials inside the extrusion tube out from the air outlet pipe, during its use, the size of the pipeline plays a very important role in the cooling effect. Therefore, it is necessary to set a too long pipeline, which occupies a large space and does not have a better cooling effect. Summary of the Utility Model
