Description
Technical field
The invention belongs to field of metallurgical equipment, the single roll crusher grate plate protection loose piece of particularly replacing for convenience detach in a kind of SINTERING PRODUCTION.
Technical background
The broken finished product sintering deposit of single-tooth roller is generally used in SINTERING PRODUCTION, interlaced arrangement three toothrow hat on circular shaft, evenly to arrange in the bottom of axle grate plate, when the shaft is rotated, crown passes through between the gap between grate plate, the bulk sintering finished ores fallen above grate plate is broken into the fritter sintering deposit being less than grate plate gap.
Because the temperature of sintering deposit is more than 300 DEG C; grate plate at high operating temperatures hardness has decline by a relatively large margin; and the impact be subject to for a long time during fragmentation; the rate of wear is very fast, and the service life of most domestic grate plate, less than 1 year, often needs grate plate all to change; larger sintering machine will change 20 polylith grate plates; cause downtime longer, affect the operating rate of sintering machine, also need larger fund.Domestic sintering industry and manufacture single roll crusher industry all find replacing construction short, can the method for local replacing, more meet the needs of SINTERING PRODUCTION.For improving the service life of rod-toothed crusher, be all inlay loose piece or protective cap at the upper surface of grate plate body, the prior art patent No. 201020638693.4 discloses a kind of combination grate plate of single roll crusher; To be connected activity helmet primarily of grate plate body, therewith grate plate body; the right-hand member of its movable helmet is connected with grate plate body by briquetting; groove is provided with at grate plate body upper part; have boss in movable helmet bottom, both are connected with groove by boss, although this structure also has processing protection simply; the advantage that use cost is low; but because movable helmet is provided with groove, under the effect of high temperature and mechanical force, movable helmet is easily along notch fracture, affects the service life of activity helmet.
In order to head it off; the patent No. 200920137619.1 discloses a kind of sintering single roll crusher grid plate device with segmental protective cover "; the sintering single roll crusher grid plate device of segmental protective cover; but due to its structure be also be provided with groove at grate plate body upper part; have boss in movable helmet bottom; during trapezoidal faces contact, upper plane will there will be gap; when going up plane contact, trapezoidal faces will there will be the problems such as gap; after being subject to larger broken impulsive force, rocking appears in loose piece; the loose piece rate of wear is accelerated, affects stability.
The patent No. 201420338281.7 discloses a kind of dovetail groove type grate plate with backplate ", the forms such as its dovetail groove are all very difficult when this structure two pieces installation, dismounting; faying face is stuck under impact force; loose piece cannot be dismantled, and there is contact area little in using, and requires that quality of fit is high.
Sintering industry can being found out all seeking a kind of energy replacing loose piece for convenience detach, the combining form grate plate of long service life, solving prior art Problems existing.
Summary of the invention
Instant invention overcomes the shortcoming and defect of prior art, provide a kind of single roll crusher grate plate protection loose piece of replacing for convenience detach, effectively solve loose piece replacing construction long, repair and maintenance labour intensity is large, reduces repair and maintenance expense.
The present invention is achieved through the following technical solutions:
The single roll crusher grate plate protection loose piece of a kind of replacing for convenience detach of the present invention, comprise grate plate body, with the protection loose piece comprising grate plate body and be connected, it is characterized in that described protection loose piece is by left part loose piece, right part loose piece and middle part loose piece formed, described left part loose piece and the joint face of right part loose piece and grate plate body are up big and down small inclined-plane, live joint face for facing directly with middle part, described left part loose piece and the normal section of right part loose piece are that top is triangular in shape, bottom has the elongate structure body of trapezoid grafting groove, bolt hole I is had in the middle and lower part of described left part loose piece and right part loose piece,
The normal section of described middle part loose piece is that top is triangular in shape, and bottom has the elongate structure body of trapezoid grafting groove, also has bolt hole II in the middle and lower part of described middle part loose piece;
Described grate plate body is that middle part is provided with the trapezoid suitable with trapezoid grafting groove
The microscler grate plate of boss, described grate plate body also has bolt hole III, described left end
During the whole trapezoid boss grafting of the trapezoid grafting groove of portion's loose piece, right part loose piece and middle part loose piece and grate plate body, plane place leaves gap, and by fastening bolt, clamp nut be arranged on spring washer between fastening bolt with clamp nut and be fixedly connected with.
Top in the trapezoid grafting groove of described left part loose piece and right part loose piece is provided with locating convex block I near loose piece side, middle part, and the correspondence position of the trapezoid boss of described grate plate body is provided with the groove matched with left part loose piece and right part loose piece locating convex block correspondence position.
Be provided with locating convex block II in the both sides of the trapezoid grafting groove inner top of described middle part loose piece, the correspondence position of described grate plate body trapezoid boss is provided with the groove matched with locating convex block II correspondence position.
Have oblique detent at the middle part of the side, inclined-plane of described left part loose piece and right part loose piece, the medial slope of described grate plate body is provided with the oblique projection suitable with oblique detent correspondence position.
Advantage of the present invention is:
The present invention is owing to have employed said structure; trapezoid groove is opened in both ends loose piece and loose piece bottom, middle part; this trapezoid groove matches with the trapezoid boss of grate plate body; this cooperation makes the contact surface of protection loose piece and grate plate body larger; trapezoidal cooperation is more convenient dismounting protection loose piece also; the inclined-plane of end loose piece and the contact of incline plane of grate plate body; because the contact surface of loose piece and grate plate body increases; produce larger impulsive force time broken to be disperseed, there will not be the phenomenon that the fast and loose piece of contact surface abrasion speed rocks like this.Efficiently solve the problem that prior art protection loose piece assembly difficulty is large, also solve because the little protection loose piece of contact area occurs the problem of rocking making extend the service life of loose piece;
During the trapezoid boss grafting of 2, the trapezoid grafting groove of left part loose piece, right part loose piece and middle part loose piece and grate plate body, plane place leaves gap, and by fastening bolt, clamp nut be arranged on spring washer between fastening bolt with clamp nut and be fixedly connected with, simple and convenient during replacing, reduce repair and maintenance workload, shorten the repair and maintenance time;
3, maintenance cost is reduced.
