Abstract
The utility model discloses a coal drop pipe with wear-resistant high chromium lining boards. The coal drop pipe with the wear-resistant high chromium lining boards comprises a coal drop pipe, wherein the coal drop pipe is aslant arranged and comprises an upper area, a lower area, a left area and a right area, the lower area is the main coal impact part, and the left area and the right area are the secondary coal impact parts; and the wear-resistant high chromium lining boards are fixedly mounted in the lower area, the left area and the right area. The coal drop pipe with the wear-resistant high chromium lining boards has the advantages of good wear-resisting property and long service life, and is convenient to mount and dismount.
Description
Technical field
The utility model relates to a kind of coal spout, more particularly, is a kind of coal spout with wear-resisting high chrome lining.
Background technology
At present, it is to be in coal or the long-term operating mode of impacting and wearing and tearing of other material that coal-fired power plant's coal handling system coal spout inwall and ball grinding mill feed and exhaust tube inwall are in operation, and the wearability defective of inner wall surface is outstanding.At present, be hit at this and method that the outstanding position of wearing and tearing is adopted the lining manganese steel plate more or shock resistance type ceramic lining plate is installed.In actual use, because manganese steel plate or shock resistance type ceramic lining plate are to the limitation of shock resistance and wear resistance, the be hit liner plate of face or abrading section of coal spout inwall and ball grinding mill feed and exhaust tube inwall breakdown or serious wear, appearance in various degree generally just can occur and leaks the phenomenon that coal leaks powder after the time of using about half a year, have a strong impact on the reliable and smooth operation of equipment.
The utility model content
It is good that the utility model aims to provide a kind of wear resisting property, the coal spout with wear-resisting high chrome lining of long service life.
The technical solution of the utility model is: a kind of coal spout with wear-resisting high chrome lining, comprise coal spout, coal spout is for being obliquely installed, coal spout is for being obliquely installed, this coal spout is made of last zone, lower area, left zone, right zone, mainly is subjected to the coal impact portion to be divided into lower area, secondly is zone, a left side and right zone, wherein, be fixedly connected with wear-resisting high chrome lining in lower area, left zone, right zone.
Above-mentioned a kind of coal spout with wear-resisting high chrome lining, described wear-resisting high chrome lining is installed in the coal spout by bolt.
Above-mentioned a kind of coal spout with wear-resisting high chrome lining, wear-resisting high chrome lining are that the high chrome lining that is spliced to form of piecemeal, its one side are suitable with the inner wall shape of coal spout.
Above-mentioned a kind of coal spout with wear-resisting high chrome lining, described coal spout is rectangular tube.
The utility model adopts above-mentioned structure, by being installed with wear-resisting high chrome lining in the lower area of coal spout, left zone, right zone, has increased the service life of coal spout greatly, reduces breakdown rate; Wear-resisting high chrome lining is fixedly mounted in the coal spout by oval head bolt, and the dismounting simple and fast is safe and reliable, improves the efficient of maintenance.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the section-drawing in the A-A cross section of Fig. 1;
Fig. 3 is high chrome lining scheme drawing of the present utility model.
Among the figure: 1 is coal spout, and 11 is last zone, and 12 is lower area, and 13 is zone, a left side, and 14 is right zone, and 15 is coal guide groove, and 2 is wear-resisting high chrome lining.
The specific embodiment
As shown in Figure 1 to Figure 3, a kind of coal spout with wear-resisting high chrome lining, comprise coal spout 1, coal spout 1 is for being obliquely installed, this coal spout 1 is made of last regional 11, lower area 12, zone, a left side 13, right zone 14, mainly being subjected to the coal impact portion to be divided into lower area 12, secondly is zone, a left side 13 and right zone 14, is fixedly connected with wear-resisting high chrome lining 2 in lower area 12, zone, a left side 13, right zone 14; Wear-resisting high chrome lining 2 is installed in the coal spout 1 by bolt; The high chrome lining that wear-resisting high chrome lining 2 is spliced to form for piecemeal, its one side suitable with the inner wall shape of coal spout 1; Coal spout 1 is rectangular tube.
When material falls to impacting the lower area 12 of coal spout 1 from coal spout, in lower area 12, zone, a left side 13 and the right zone 14 of coal spout 1 wear-resisting high chrome lining 2 is installed by bolt, material does not directly impact coal spout 1, and is discharged to coal guide groove 15 by wear-resisting high chrome lining 2 from coal spout 1 outlet.
