Abstract
The utility model discloses a self-fastening coal mill liner without a bolt for a coal mill in the industries of power plants, metallurgy, mines, building materials and the like, comprising a cylinder body and a plurality of liners, wherein the surface shape of the bottom surface of each liner is adapted to that of the inner surface of the cylinder body, and the plurality of liners are inlaid in and fixed to the cylinder body two by two. After being installed, the liners tightly cling to the cylinder body of the coal mill self, and only little liners are convenient to disassemble and fixed with bolts, therefore, the tightness of the cylinder body is greatly improved, the phenomenon that the liners drop caused by broken bolts of the cylinder body is completely eliminated, the repair and maintenance times of the coal mill are reduced, the utilization efficiency of the liners is fully exerted, and the safety economic running of equipment is ensured.
Description
Technical field
The utility model relates to a kind of coal pulverizer in sector applications such as power plant, metallurgy, mine, building materials, relates in particular to coal pulverizer and uses liner plate.
Background technology
At present, coal pulverizer has all obtained widely using in industries such as power plant, metallurgy, mine, building materials, and the effect of coal pulverizer is that abrasive body and material roll to the other end from liner plate one end when material is ground by abrasive body in cylindrical shell.Phenomenons such as coal pulverizer that can be present is because most of bolt liner plate that adopts, and it hits in the operation process in high strength, and bolt will inevitably produce fracture, become flexible.Can cause powder after bolt looseness or the fracture with Louing, fall liner plate etc., both pollute production environment, increase each item recondition expense of coal pulverizer again, normally keep the safety in production for the user and bring suitable trouble and puzzlement.China utility model patent CN201537513U discloses a kind of leakproof ball mill barrel; Cylinder inboard wall is provided with liner plate; Be provided with rubber slab between said liner plate and the cylinder inboard wall, through bolt with liner plate with rubber slab is disposable is pressed abd fixed on the cylinder inboard wall, though rubber slab can guarantee that ball mill barrel is at not spillage in service for a long time; Also play the effect that reduces coal pulverizer noise, protection cylindrical shell steel plate; But it can not fundamentally solve the problem of bolt fracture, is in operation because the defective of structural design causes maintenance workload big, difficult in maintenance, serious causes the improper stoppage in transit of generating set.
The utility model content
It is a kind of from fastening type non-bolt coal pulverizer liner plate that the utility model purpose is to provide, and liner plate adopted be fixed on the cylindrical shell from fastening mode, fundamentally solves the problem of bolt fracture in the prior art.Thoroughly eliminate the phenomenon that cylindrical shell falls liner plate, reduced the maintenance and the maintenance number of times of coal pulverizer, given full play to the utilization ratio of liner plate, guaranteed the safety and economic operation of equipment.
The technical scheme that realizes the utility model purpose is:
A kind ofly comprise cylindrical shell and some blocks of liner plates from fastening type non-bolt coal pulverizer liner plate, the surface configuration of said liner plate bottom surface and cylinder inner surface is suitable, it is characterized in that: said some blocks of liner plates phase build-in in twos fix on the cylindrical shell.
The cross section of said liner plate is a kind of in balancing waveform, waveform, tooth ripple and the trapezoidal ripple.
The utility model compared with prior art has following advantage:
1. after the installation of liner plate, liner plate self is attached on the cylindrical shell body of coal pulverizer tightly, only has to be convenient on a small quantity dismantle to use set bolt; So just increased the tightness of cylindrical shell widely, because the circumference arch form characteristic of coal pulverizer cylindrical shell, when coal pulverizer turns round; Liner plate phase embedding is in twos hit down pounding of steel ball, has corresponding stretching, extension and Zhang Yan; So along with the running and the steel ball of coal pulverizer are pounded the effect of hitting down the self-tightening power that stretches and produce; Be fixed on tightly on the coal pulverizer cylindrical shell, can not collapse the purpose that bolt does not stress thereby reach the coal pulverizer liner plate.Thoroughly eliminated cylindrical shell since Broken bolt cause the liner plate phenomenon, reduce the maintenance and the maintenance number of times of coal pulverizer, give full play to the utilization ratio of liner plate, guaranteed the safety and economic operation of equipment.
2. because of the shutoff to about 95% bolt hole, effectively stopped coal dust and leaked the powder phenomenon, environmental protection effect is obvious.
Description of drawings
Fig. 1 is the said structural representation from fastening type coal pulverizer cylindrical shell of the utility model.
Fig. 2 be among Fig. 1 A to diagrammatic sketch.
⒈ liner plate ⒉ cylindrical shell.
The specific embodiment
Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model, and all technical schemes that are equal to also belong to the category of the utility model, and the scope of patent protection of the utility model should be limited each item claim.
From Fig. 1 and Fig. 2, can find out; A kind of from fastening type non-bolt coal pulverizer liner plate; Comprise cylindrical shell 2 and some blocks of liner plates 1, the surface configuration of said liner plate 1 bottom surface and cylindrical shell 2 inner surfaces is suitable, it is characterized in that: said some blocks of liner plates 1 phase build-in in twos fix on the cylindrical shell 2.The cross section of said liner plate 1 is a kind of in balancing waveform, waveform, tooth ripple and the trapezoidal ripple.
Claims (2)
1. one kind from fastening type non-bolt coal pulverizer liner plate, comprises cylindrical shell ⑵ and some liner plate ⑴, and the surface configuration of said liner plate ⑴ bottom surface and cylindrical shell ⑵ inner surface is suitable, it is characterized in that: said some liner plate ⑴ phase build-in in twos fix on the cylindrical shell ⑵.
2. according to claim 1 a kind of from fastening type non-bolt coal pulverizer liner plate, it is characterized in that: the cross section of said liner plate ⑴ is a kind of in balancing waveform, waveform, tooth ripple and the trapezoidal ripple.
