Counter-blowing type hot-cutting hood with cooling effect

Abstract

The invention discloses a counter-blowing type hot-cutting hood with a cooling effect and relates to the technical field of mechanical equipment. A first round rabbet (1) is formed in one side of a hood body (3); a second round rabbet (2) is formed in the other side of the hood body (3); water inlet pipe joint (4) and a water outlet pipe joint (5) are arranged on two sides of the periphery of the hood body (3); a high-pressure fan blowing-in joint pipe (6) is arranged at one end of the lower part of the hood body (3); a discharging pipeline (7) is arranged at the other end of the lower part of the hood body (3); the high-pressure fan blowing-in joint pipe (6) is communicated with the discharging pipeline (7). The counter-blowing type hot-cutting hood has the beneficial effects that a material bonding problem is solved, and an inner cavity of the hot-cutting hood is not prone to block; the hot-cutting hood is simple in structure, convenient to use and operate and easy to air and cool, the time-saving and labor-saving effects are achieved, and the production efficiency is improved.

Description

Technical field: [0001] The invention relates to the technical field of mechanical equipment, in particular to a blow-through heat cutting hood with cooling function. Background technique: [0002] In actual production, generally according to the type and characteristics of the processed materials, the extruder head and die, and the corresponding auxiliary equipment after pelletizing are selected. Pelletizing can be divided into hot cutting and cold cutting. The material is cut off by the rotating knife as soon as it is extruded from the die of the extruder, and then cooled by air or water. Or water-cooled and then cut into particles by another independent granulator. In the above-mentioned hot granulation method, the granulated particle materials need to be air-dried and cooled, and must be collected before being transported to the relevant equipment behind through the pipeline. Existing granulation cover is only the cover body that is enclosed within the machine head part...

AI Technical Summary

Problems solved by technology

The particles that have just been granulated are often not cooled down quickly due to the temperature, and are easy to stick into agglomerates, or stick to the inner wall of the hot cutting hood, blocking the material conveying pipeline, seriously affecting the normal conveying of materials, causing downtime accidents, and It is necessary to manually disassemble the pelletizing cover for cleaning and maintenance, otherwise it will not be able to produce normally, the operation is cumbersome, time-consuming and laborious, reducing production efficiency, and the sticky materials are also unqualified
