Description

Curtain device with dustproof sound absorption function

Technical Field

The utility model relates to a dustproof sound absorbing material technical field specifically is a separate curtain device with dustproof sound absorption.

Background

In recent years, the environmental noise problem more and more seriously affects the life, work and study of people, and becomes one of three public hazards of society together with air pollution and water pollution, in textile enterprises, because machines such as looms, spinning frames and the like have large noise, are sharp and harsh, have wide pollution surfaces, the noise is generally 95-105 decibels, and the physical and mental health of workers and residents around factories is seriously harmed, so that enough attention needs to be paid to the control of textile noise.

Although the existing sound absorption and noise removal technology is well applied to different fields, a considerable part of sound absorption materials have the factors of poor environmental adaptability, large volume, single function, high construction cost and the like, and are not popularized in a large range all the time; therefore, the sound-absorbing material which is harmless to human body, multifunctional and efficient, such as sound absorption, fire prevention, flame retardation and dust prevention, becomes a hot spot of current research.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: to the not enough that prior art exists, provide a separate curtain device with dustproof sound absorption, changed traditional function singleness, only have dustproof separate the curtain, except having the acoustical performance of sound absorption noise removal, satisfy simultaneously in addition that the enterprise prevents fires requirements such as insulating and pollution-free.

The technical scheme is as follows: the utility model provides a separate curtain device with dustproof sound absorption, includes organic glass and attached multifunctional fiber net check cloth on the organic glass upper and lower surface that has fire-retardant function, organic glass comprises upper surface, middle structure, lower surface, upper surface, middle structure, lower surface are integrated into one piece, be equipped with a plurality of cavitys between upper surface and the middle structure, between lower surface and the middle structure, be equipped with a plurality of through-holes on upper surface and the lower surface, through-hole and cavity intercommunication.

Preferably, the aperture of the through hole is 0.5-2 mm.

Preferably, the grid lines in the grid cloth are formed by twisting bamboo pulp fibers, polytetrafluoroethylene fibers and carbon fibers.

Preferably, the cavity between the upper surface and the intermediate structure and the cavity between the lower surface and the intermediate structure are symmetrically arranged.

Preferably, the through holes on the upper surface and the lower surface of the organic glass are arranged in the center of the cavity.

Preferably, the contact surface of the organic glass and the mesh cloth is coated with a flame retardant.

Has the advantages that: compared with the prior art, the utility model has the advantages of it is following: the grid lines in the grid cloth are formed by twisting bamboo pulp fibers, polytetrafluoroethylene fibers and carbon fibers, have high temperature resistance and sound absorption functions, and can protect the middle organic glass; organic glass of band stop fire-retardant function, this organic glass's acoustic resistance itself is limited, through the cavity in organic glass, leaves the air bed of certain thickness to be equipped with the through-hole on the cavity, reach the sound absorption function, this separates curtain device easily cutting process, construction convenience, through net cloth, improve and separate the curtain device high temperature resistant, inhale the sound function.
