Abstract
The utility model discloses a blower casing capable of realizing wear-resistant lining board replacement, which includes a blower casing, wherein two and more wear-resistant sound absorbing boards are fixed on the inner side of the blower casing in the circumferential direction to completely cover the circumference on the inner side of the blower casing, and are fixed on a blower lining board; and the blower lining board is movably fixed on the inner side of the blower casing. The blower casing capable of realizing wear-resistant lining board replacement has the characteristics of excellent wearing resistance, low noise, longer service life and low maintenance cost.
Description
Technical field
The utility model belongs to the Fan Equipment technical field, especially relates to a kind of fan casing that is used for the replaceable wear liner plate of work under bad environment such as road sweeper tool.
Background technique
At present, existing fan casing is in order to strengthen the wear resistance of casing, and the overwhelming majority adopts the casing of wear resistance electrode built-up welding and installed a wear-resisting steel plate additional through bolt; Though this mode has increased the wear resistance of casing; But picture is used on the more abominable blower fan of working environment such as road sweeper tool, and the working life of casing is still very low, in case can not repair after the casing wearing and tearing; Can only change whole casing assembly; User cost is too high, and the sandstone that get into blower fan have at a high speed directly produced noise pollution to casing.
Summary of the invention
The purpose of the utility model be to improve the deficiency of prior art and provide that the fan casing wear resistance is good, noise is little, the fan casing of working life is long, maintenance cost is low replaceable wear liner plate.
The purpose of the utility model is achieved in that a kind of fan casing of replaceable wear liner plate, is made up of fan casing, is characterized in being fixed with wear-resisting acoustical panel at the inboard circumferencial direction of fan casing.
In order further to realize the purpose of the utility model, can be the circumference that 2 and above wear-resisting acoustical panel cover the fan casing inboard fully.
In order further to realize the purpose of the utility model, can be that wear-resisting acoustical panel is fixed on the blower fan liner plate, the activity of blower fan liner plate is fixed on the fan casing inboard.
In order further to realize the purpose of the utility model, can be that the inner side surface at the blower fan liner plate is equipped with wear-resisting acoustical panel, be connected to fixing bolt at the blower fan liner plate towards casing one face down bonding, fixing bolt with casing on the bolt hole matching and fixing.
Compared with present technology the utility model has following distinguishing feature and good effect: the utility model is to be fixed with wear-resisting acoustical panel in fan casing inside circumference direction; Fan casing inside circumference direction is the maximum positions of blower fan work shell on opportunity wearing and tearing; Strengthen the scurf resistance of fan casing like this, and after wear-resisting acoustical panel wearing and tearing, can change wear-resisting acoustical panel; Need not change whole fan casing; Have good economic benefit, reduced maintenance cost, the noise when also having reduced simultaneously blower fan work; 2 and above wear-resisting acoustical panel cover the inboard circumference of fan casing fully; The one, guaranteed that wear-resisting acoustical panel and casing are inboard well identical; Protect casing, reduced noise, also can prolong the working life of wear-resisting acoustical panel simultaneously; The 2nd, can change the wear-resisting acoustical panel of serious wear as required, reduced the repair and replacement cost; Wear-resisting acoustical panel is fixed on the blower fan liner plate, and the activity of blower fan liner plate is fixed on the fan casing inboard, is convenient to the wear-resisting acoustical panel of repair and replacement; The inner side surface of blower fan liner plate is equipped with wear-resisting acoustical panel, is connected to fixing bolt at the blower fan liner plate towards casing one face down bonding, fixing bolt with casing on the bolt hole matching and fixing; Wear-resisting like this acoustical panel and casing liner plate have guaranteed good conformity; The distance of mounting hole is the same, can be used as standard piece, and is easy for installation between each wear-resisting acoustical panel and the casing; Improve maintenance efficiency, reduced maintenance cost.
