Shock absorption and noise elimination shell of draught fan

Abstract

The invention discloses a shock absorption and noise elimination shell of a draught fan. The shock absorption and noise elimination shell of the draught fan comprises a draught fan body and a motor; a draught fan bin is arranged on the draught fan body, and a polyester silencing cotton layer is arranged on the inner wall of the draught fan bin; a sound absorbing material layer is arranged on the inner layer of the polyester silencing cotton layer; the motor is arranged on the right side of the draught fan body, and fixing blocks are fixed to the upper end and the lower end of the motor; the fixing blocks are hinged to one ends of supporting rods through hinge shafts; the outer ends of movable bins at the lower ends are both fixed to the draught fan body; second sliding blocks are fixed to the two sides of the movable bins, and the second sliding blocks are slidably connected with second sliding rails; and the second sliding rails are both arranged on the inner walls of the movable bins. The shell of the draught fan is provided with the draught fan bin, the polyester silencing cotton layer and the sound absorbing material layer, through the arrangement, the shell in the draught fan bin can weaken noise generated inside when the motor drives the draught fan bin to work, and the working environment around the draught fan body is prevented from being affected.

Description

technical field [0001] The invention relates to the technical field of fan casings, in particular to a shock-absorbing and noise-absorbing casing of a fan. Background technique [0002] Fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven flow machine. The existing fan casing basically meets people's needs, but there are still some problems during use. [0003] 1. The existing fan casing is only grounded to the ground to ensure the simple support of the fan itself. When the traditional fan housing and the motor are connected to the casing, when the motor is working, the vibration generated by the motor itself will be transmitted to the casing, and then transmitted to the casing. For the entire fan, this will cause the screw fasteners on the fan to loosen for a long time, and reduce the life of the fan itself. [0004] 2. When the existing fan is driven by the motor to work in the fan cabin, it will generate a lot...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a shock-absorbing and noise-absorbing shell of a fan to solve the problem that the existing shell at the connection between the fan and the motor proposed in the background art will vibrate due to the working of the motor, which will cause the entire fan to vibrate and reduce the life of the fan, and The problem that the sound-absorbing effect of the shell in the fan compartment is poor
