Abstract

A sound reducing box of a single-stage high-speed blower comprises a box body, a cooling air inlet hole, a cooling air outlet pipe and an axial-flow fan, wherein the inner sides of both the box body and the door leaves adopt sound reducing pore plates, while the outer sides of both the box body and the door leaves adopt galvanized plates; sound insulating materials are packed between the sound reducing pore plates and the galvanized plates. The sound reducing box covers the single-stage high-speed blower to achieve a sound reducing function; the cooling air inlet hole in one side of the box body and the axial-flow fan mounted on the cooling air outlet pipe at the top of the box body form a forced air cooling system so as to keep the circulation between the interior of the box body and the external air and achieve the purpose of cooling by the blower; with the door leaves on the box body, in case of blower failure, a maintenance worker can open the door leaves to maintain and debug the blower; the box body is assembled with a plurality of groups of unit modules, and assembly can be performed by unit modules of different specifications and different numbers according to the size of the blower, so that the transportation and mounting are facilitated.

Description

A kind of single-stage high-speed blower Sound Attenuator
Technical field
The present invention relates to a kind of single-stage high-speed air blower silencer.
Background technique
Single-stage high-speed blower is a kind of high pressure ventilation equipment, it when operation motor and impeller can produce very large noise, also can produce high temperature simultaneously, if blower fan is isolated to noise reduction with enclosed construction, ventilation effect extreme difference, blower fan can not be dispelled the heat in time, and when particularly summer temperature is too high, blower fan almost cannot be worked.
Summary of the invention
Object of the present invention is exactly to overcome the deficiency that prior art exists, and provide a kind of, can noise reduction can keep the cooling a kind of single-stage high-speed blower Sound Attenuator of blower fan.
To achieve these goals, the technical solution adopted in the present invention is: a kind of single-stage high-speed blower Sound Attenuator, by casing, cooling air intake opening 7, cooling air air outlet tube 8, axial-flow blower 13, formed, it is characterized in that: casing is comprised of top board 1, left sideboard 2, front plate 3, right sideboard 4, backboard 5 and framework 6; Cooling air air outlet tube 8 is housed on top board 1, and has blower air outlet tube 10 mounting holes; Axial-flow blower 13 is installed on cooling air air outlet tube 8; On left sideboard 2, have cooling air intake opening 7; Front plate 3 and backboard 5 are provided with door leaf, and keeper handle 11 is housed on door leaf, and backplate 5 has control cabinet putting hole 14; On right sideboard 4, have blower air intake pipe 9 mounting holes.
Above-described a kind of single-stage high-speed blower Sound Attenuator, is characterized in that: described case basis and door leaf inner side adopt muffling hole plate, and outside adopts galvanized sheet, between muffling hole plate and galvanized sheet, is filled with soundproof material.
Above-described a kind of single-stage high-speed blower Sound Attenuator, it is characterized in that: described casing is that unit module assembles, top board 1 is divided into a plurality of unit modules, and one of them unit module is equipped with cooling air air outlet tube 8, and another unit module has blower air outlet tube 10 mounting holes; Front plate 3 and backboard 5 are door leaf unit module, and left sideboard 2 and right sideboard 3 are respectively perforate unit module independently, and framework 6 is separate unit module.
This Sound Attenuator is covered on single-stage high-speed blower, there is noise reduction, cooling action.
The beneficial effect that the present invention compared with the existing technology had is: the noise isolation that the present invention can send blower fan, the axial-flow blower 13 of installing on cooling air intake opening 7 on casing side and the cooling air air outlet tube 8 at top has formed the forced air cooling, make case body interior and ambient air circulation, reached the cooling object of blower fan; Casing is provided with door leaf, and when blower fan breaks down, maintenance man can overhaul debugging to blower fan by opened door leaf; Casing, for how group unit modules assemble, selects different size unit module and quantity to assemble according to the size of blower fan, is convenient to transportation and installs.
