Abstract
The utility model relates to a silencer of a high-speed wire rod rolling cold air control fan. The surface of the periphery of a volute of the centrifugal cold air control machine is wrapped with a layer of sound-absorbent materials for blocking impact noise and friction noise generated when high-speed airflow in the fan impacts the volute, and the surfaces and the interiors of a rectifying cone and a rectifying barrel at air inlets in the two sides of the cold air control fan are filled with silencing materials. The silencer is simple in structure and convenient to transform; in the actual production application, the combination structure of wrapping type silencing and inlet absorbent silencing can reduce noise by about 15dB.
Description
Affiliated technical field
The utility model belongs to the noise reduction additional device of the cooling blower using in a kind of steel rolling production, is a kind of silencer of high-speed wire rolling control air cooler specifically.
Background technique
In high-speed wire rolling production process, the control air cooler of controlling cooling stage is the Main Noise Sources of whole manufacturing shop.In industry, the centrifugal control air cooler of application is without silencer or measure at present, and the noise producing in actual production causes tremendous influence to Environmental Conditions.
Summary of the invention
The utility model is exactly a kind of high-speed wire rolling control air cooler silencer for the shortcoming design of prior art, reduces control air cooler noise, improves working environment.
The utility model solves the technological scheme that its technical problem adopts: design a kind of high-speed wire rolling control air cooler silencer, at the coated one deck of the spiral case peripheral surface of centrifugal control air cooler, be used for producing while blocking blower fan high speed gas shock spiral case the quieter material of impact noise and friction noise, at fairing cone and flow regulating barrels surface and the inner quieter material of filling of the both sides intake grill of control air cooler.The coated quieter material of spiral case peripheral surface by the orifice layer of the clad of outside, the inside and two-layer between the superfine glass fiber silk layer of filling form, fairing cone and flow regulating barrels surface be orifice layer, inside filling superfine glass fiber silk.
The beneficial effects of the utility model are that simple in structure, conveniently, in production application, this clad type noise reduction adds the composite structure of entrance absorption noise reduction, can reduce noise 15dB left and right in transformation.
Accompanying drawing explanation
Fig. 1 is the utility model volute section separation structure schematic diagram.
Fig. 2 is the utility model spiral case and wind inlet part-structure schematic diagram.
Embodiment
Make high-speed wire rolling control air cooler silencer, at the coated quieter material of spiral case 1 peripheral surface of centrifugal control air cooler, at fairing cone 8 and flow regulating barrels 5 surfaces and the inner quieter material of filling of the both sides intake grill of control air cooler.The coated quieter material of spiral case peripheral surface by the orifice layer 4 of the clad 2 of outside, the inside and two-layer between the superfine glass fiber silk layer 3 of filling form, fairing cone 8 and flow regulating barrels 5 surfaces are orifice layer 6,7, the inner superfine glass fiber silk of filling, clad is fixed by bolts to spiral case 1 outer surface.This clad type noise reduction adds the composite structure of entrance absorption noise reduction, can reduce noise 15dB left and right.
