Problems solved by technology

[0002] The single-stage high-speed blower is a kind of high-pressure ventilation equipment. When it is running, the motor and impeller will generate a lot of noise and high temperature. If the fan is isolated and silenced with a closed structure, the ventilation effect will be extremely poor, so that the fan cannot be timely Heat dissipation, especially when the temperature is too high in summer, the fan can hardly work

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

technical field [0001] The invention relates to a single-stage high-speed blower noise reduction device. Background technique [0002] The single-stage high-speed blower is a kind of high-pressure ventilation equipment. When it is running, the motor and impeller will generate a lot of noise and high temperature. If the fan is isolated and silenced with a closed structure, the ventilation effect will be extremely poor, so that the fan cannot be timely Heat dissipation, especially when the temperature is too high in summer, the fan can hardly work. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a single-stage high-speed blower sound-absorbing box which can not only eliminate noise but also keep the fan cooling. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a single-stage high-speed blower soundproof box, which is composed of a b...
