Granulation extruder air-cooled cooling pipe noise reduction device

Abstract

The invention discloses a granulation extruder air-cooled cooling pipe noise reduction device which comprises a material conveying pipe, cooling pipes and soundproof sponge. The material conveying pipe is used for connecting a fan and a material bin and for conveying materials, the cooling pipes are fixed outside the material conveying pipe in an electrowelding manner, the cooling pipes are externally connected with circulating cooling water, and the whole material conveying pipe and the cooling pipes are externally wrapped with the soundproof sponge tightly. The granulation extruder air-cooled cooling pipe noise reduction device is simple in structure and reasonable in design, the problem of material cooling is solved, meanwhile environmental noise is effectively controlled, and the healthy hidden trouble of operation workers is lowered.

Description

technical field [0001] The invention relates to a noise reduction device for an air-cooled cooling pipe of a granulation extruder. Background technique [0002] During the granulation and extrusion process of plastics, after the materials are plasticized at high temperature, plastic pellets with processing properties are obtained by pelletizing. At this time, the pellets are still kept at high temperature, and in engineering applications, through multi-stage air cooling, vibrating sieving and other links, the finished materials that meet the requirements are obtained. In the air-cooling process, blowers are generally used to blow high-temperature pellets into multi-stage silos through metal material conveying pipes. During the conveying process, the materials are constantly rolling and moving to achieve the purpose of gradually cooling down and avoiding the adhesion between materials. At the same time, the metal conveying pipe can effectively dissipate heat, which is conduc...

Problems solved by technology

Caused long-term harm to the health of workers and environmental protection

However, in general production, the sound cannot be silenced outside the conveying pipe, otherwise it will cause poor heat dissipation in the pipe, aggravate the adhesion of materials, and hinder normal production
