Abstract
The invention discloses a blower casing of a pulverizer, which comprises a casing, a lining plate high in anti-abrasion performance is arranged on the inner circumferential surface of the casing; holes matched with countersunk head screws are uniformly formed in the lining plate and are corresponding to countersunk head screws in the casing; the lining plate is fixedly connected with the casing via the countersunk head screws. The blower casing of the pulverizer has the remarkable advantages of simple process, low cost and long service life.
Description
Technical field:
The present invention relates to the blower housing of a kind of blower fan, particularly a kind of pulverizer.
Background technology:
The blower housing of pulverizer generally has two kinds, and a kind of for the monoblock cast structure, another kind is welded-steel plate construction, and the former complex process cost is high, but long service life, and the simple cost of latter process is low but owing to being that metal sheet is short service life.
Summary of the invention:
The object of the invention provides the blower housing of a kind of pulverizer of the low and long service life of the simple cost of a kind of technique.
The technical scheme that realizes the object of the invention is, a kind of blower housing of pulverizer, comprise shell, it is characterized in that: the inner peripheral surface of described shell is provided with the high liner plate of anti-wear performance, the sunk screw hole that is evenly equipped with on the described liner plate on the described shell of the Kong Bingyu that matches with sunk screw is relative, and described liner plate is connected by sunk screw and described shell.
The present invention has the remarkable advantage that the simple cost of technique is low and the life-span is long compared with the prior art.
Description of drawings:
Fig. 1 is structural representation of the present invention.
The specific embodiment:
The present invention is on original welded-steel plate construction basis, inner peripheral surface at shell 1 arranges the high liner plate of anti-wear performance 2, this liner plate adopts the gray iron liner plate, its mode that is connected is, be evenly equipped with the hole that matches with sunk screw 3 on the liner plate, and relative with the sunk screw hole on the shell, by sunk screw liner plate is fixed on the inner peripheral surface of blower housing.This interior lining panel blower housing that is provided with not only has technique simple, the advantage of the low long service life of cost, and also replaceable and do not need integral replacing behind wear liner, renewal cost is low.
