Description

Technical Field

[0001] The utility model relates to the technical field of biodegradable materials, in particular to an extruder cooling device used for the production of biodegradable material products. Background Art

[0002] Biodegradable materials and products refer to materials and products that can be completely decomposed into low-molecular compounds by microorganisms (such as bacteria, fungi and algae) under appropriate and definable natural environmental conditions. Biodegradable materials and products are widely used in many fields and are produced in large quantities for use.

[0003] According to the authorization announcement number CN215903947U, an extruder cooling device for the production of biodegradable material products is disclosed, wherein a heat conduction component is arranged on the outside of the extrusion tube, a rubber cooling tube is movably embedded in the embedded groove, two clamping grooves are respectively clamped on both sides of the spring steel plate, positioning clamping grooves are provided on the inner walls on both sides of the clamping strip, an extrusion strip is inlaid on the open end of the U-shaped positioning tube, a water pressure plate is bonded to one side of the extrusion strip, semicircular tiles are sleeved on the top and bottom surfaces of the outer side of the extrusion tube, a reflux component is connected to the end of the butt-joint tube, the water inlet end of the water pump is connected to the water tank, a filter box is movably embedded in the treatment box near one end of the water tank, exhaust holes are evenly provided on the outside of the ventilation ring, and several ventilation rings are connected to the air pump. The spring steel plate of the above application is spirally installed in the embedded groove, and the semicircular tile is wrapped and fixed to facilitate heat conduction. Heat exchange is performed when water flows through the rubber cooling tube, and the rubber cooling tube is easy to disassemble, so it is convenient to clean the spring steel plate, and the cleaning is more convenient and quick.

[0004] However, the above application still has shortcomings. The extruded material of the discharge pipe is cooled by winding the rubber cooling pipe around the outside of the discharge pipe in sequence. However, when water flows from one end of the pipe to the other end of the pipe, the water in the rubber cooling pipe participates in the heat exchange reaction many times during the flow outside the discharge pipe. As the temperature of the water increases, the cooling efficiency of the other end of the discharge pipe will decrease, resulting in uneven cooling of the discharge material. Utility Model Content
