Draught fan with damping and noise reduction functions

Abstract

The invention belongs to the technical field of draught fans, and relates to a draught fan with damping and noise reduction functions. The draught fan comprises a shell, a bottom plate, a damping mechanism, a first noise reduction mechanism, a second noise reduction mechanism and an adjusting mechanism, wherein an arc-shaped accommodating groove is formed in the head of the shell, a mounting bracket is arranged in the shell, a motor is mounted on the mounting bracket, detachable mesh enclosures are arranged at the front end and the rear end of the shell, two symmetrically arranged first lifting rings are arranged at the top of the shell, two supporting bases, the damping mechanism, the first noise reduction mechanism, the second noise reduction mechanism and the adjusting mechanism are arranged on the bottom plate, the bottom plate is fixedly connected to the top of the damping mechanism, the shell is rotationally connected to the two supporting bases, the adjusting mechanism is fixedly connected with one of the supporting bases, the first noise reduction mechanism is arranged in the arc-shaped containing groove, and the second noise reduction mechanism is arranged on the mountingbracket. According to the draught fan, vibration generated when the draught fan works is counteracted through the damping mechanism, so that the service life of the draught fan is prolonged, noise generated when the draught fan works is absorbed through the first noise reduction mechanism and the second noise reduction mechanism, and noise pollution is eliminated.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a fan with functions of shock and noise reduction. Background technique [0002] Fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. In addition to the traditional application fields, the ventilation of various places will still have a relatively large market potential in more than 20 potential market fields such as comprehensive utilization of coal gangue, technical transformation of new dry process clinker, energy saving in the metallurgical industry, and comprehensive utilization of resources. Prospects. At present, the fan will generate large vibration and noise during operation. Excessive vibration will affect the service life of the fan. Excessive noise will cause noise pollution, which will have a negative impact on human health. Contents of the invention [0003] The technical problem to be solved by the present invention i...
