Description

A sound insulation cotton waste recycling system

This patent application is a divisional application with the application number: 2015101651729. The filing date of the original application is: 2015-04-09. The name of the invention is: a sound insulation cotton waste recycling system.

technical field

The invention belongs to the technical field of resource recycling, and more specifically relates to a recycling system for sound-insulating cotton waste.

Background technique

The main noise source of the outdoor unit of the air conditioner is the compressor part, and the operating noise of the air conditioner compressor is relatively large; in order to reduce the noise of the air conditioner compressor, the noise problem is generally solved through resonance analysis and system matching. At present, the commonly used noise reduction technology for outdoor units of air conditioners mainly realizes sound reduction through the principle of preventing the propagation of sound waves. Existing air-conditioning outdoor units use sound-proof cotton, which is wrapped around the cylinder of the compressor, wrapped around the periphery of the pipeline, and a top felt is installed on the top of the compressor to solve the problem of air-conditioning by absorbing sound waves and isolating sound waves from outside. The noise of the compressor is absorbed, so as to absorb the sound wave energy of each frequency band radiated by the compressor, so as to achieve the effect of greatly reducing the noise.

In the prior art, after the sound insulation cotton is produced into a specific shape, it must be cut into the required structural shape. Therefore, a large amount of sound insulation cotton cutting waste will be produced in the process of producing the finished sound insulation cotton. For this reason, usually The sound insulation cotton cut waste will be recycled and reused, and recycling usually takes certain steps of crushing and separation. One is to crush the sound insulation cotton cut waste to facilitate melting and recasting, and the other is to ensure that the melted waste The singleness, that is, its purity, usually separates the cut waste of sound insulation cotton, and recycles and melts the waste of a single material after separation, which will greatly reduce the production cost.

At present, in the existing public technology, there are devices and methods for crushing and separating sound-insulating cotton, but there has not been a separation device for sound-insulating cotton, nor has there been a device or method for recycling sound-insulating cotton waste, that is, it has not yet appeared. With regard to the crushing and separating device for the sound-insulating cotton waste, the prior art also lacks a dust removal and recovery device for the separated sound-insulating cotton waste.

Therefore, there is an urgent need for a production line and method for crushing, separating and dedusting soundproof cotton to realize the recycling and reuse of soundproof cotton waste, that is, a soundproof cotton waste recycling system.
