Description
Technical field
The utility model belongs to field of metallurgical equipment, particularly the single roll crusher grate plate of replacing for convenience detach protection loose piece in a kind of SINTERING PRODUCTION.
Background technology
In SINTERING PRODUCTION, generally use the broken finished product sintering deposit of single-tooth roller, interlaced arrangement three toothrow hats on circular shaft, the grate plate of evenly arranging in the bottom of axle, in the time that axle rotates, crown passes through between the gap between grate plate, and the bulk sintering finished ores of falling above grate plate is broken into the fritter sintering deposit that is less than grate plate gap.
Because the temperature of sintering deposit is more than 300 DEG C; grate plate hardness under the condition of high temperature has decline by a relatively large margin; and the impact while being subject to fragmentation for a long time; the rate of wear is very fast, and the less than 1 year in service life of most domestic grate plate, often need to all change grate plate; larger sintering machine will be changed 20 polylith grate plates; cause downtime longer, affect the operating rate of sintering machine, also need larger fund. Domestic sintering industry and the industry of manufacturing single roll crusher are all being found short, method that can local replacing of replacing time, more meet the needs of SINTERING PRODUCTION. For improving the service life of rod-toothed crusher, be all to 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; Mainly by grate plate body, the grate plate body activity helmet that is connected therewith; the right-hand member of its movable helmet is connected with grate plate body by briquetting; be provided with groove on grate plate body top; 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, easily along notch fracture, affects the service life of activity helmet.
For 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 because its structure is to be also provided with groove on grate plate body top; have boss in movable helmet bottom; when trapezoidal faces contact, upper plane will there will be gap; when upper 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, affected 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 two installations of this structure, dismounting; under impulsive force, faying face is stuck; loose piece cannot be dismantled, and exists contact area little in use, requires quality of fit high.
Can find out sintering industry all seeking a kind of can replacing loose piece for convenience detach, the combining form grate plate of long service life, solves the problem that prior art exists.
Summary of the invention
The utility model has overcome the shortcoming and defect of prior art, and a kind of single roll crusher grate plate protection loose piece of replacing for convenience detach is provided, and has effectively solved the loose piece replacing time long, and repair and maintenance labour intensity is large, minimizing repair and maintenance expense.
The utility model 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 utility model, comprise grate plate body, with the protection loose piece that comprises that grate plate body is 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 form, the joint face of described left part loose piece and right part loose piece and grate plate body is up big and down small inclined-plane, with middle part loose piece joint face for facing directly, 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, middle and lower part at described left part loose piece and right part loose piece has bolt hole I,
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 the microscler grate plate that middle part is provided with the trapezoid boss suitable with trapezoid grafting groove, on described grate plate body, also have bolt hole III, when the whole trapezoid boss of the trapezoid grafting groove of described left part loose piece, right part loose piece and middle part loose piece and grate plate body is pegged graft, plane place leaves gap, and by fastening bolt, clamp nut and be arranged on fastening bolt and clamp nut between spring washer 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 middle part loose piece side, is provided with the groove matching with left part loose piece and right part loose piece locating convex block correspondence position on the trapezoid boss of described grate plate body.
Both sides at the trapezoid grafting groove inner top of described middle part loose piece are provided with locating convex block II, on described grate plate body trapezoid boss, are provided with the groove matching with locating convex block II correspondence position.
Middle part in the inclined-plane side of described left part loose piece and right part loose piece has oblique detent, is provided with the oblique projection suitable with oblique detent correspondence position on the inclined-plane, inner side of described grate plate body.
The utility model has the advantages that:
The utility model is owing to having adopted 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 to protect the contact-making surface of loose piece and grate plate body larger; trapezoidal cooperation is more convenient dismounting protection loose piece also; the inclined-plane of end loose piece contacts with the inclined-plane of grate plate body; because the contact-making surface of loose piece and grate plate body increases; when broken, produce larger impulsive force and disperseed, there will not be like this phenomenon that contact surface abrasion speed is fast and loose piece rocks. Effectively solve the large problem of prior art protection loose piece assembly difficulty, also solved because the problem of rocking appears in the little protection loose piece of contact area, extended the service life of loose piece;
2, when the trapezoid grafting groove of left part loose piece, right part loose piece and middle part loose piece and the trapezoid boss of grate plate body are pegged graft, plane place leaves gap, and by fastening bolt, clamp nut and be arranged on fastening bolt and clamp nut between spring washer be fixedly connected with, simple and convenient when replacing, reduce repair and maintenance workload, shortened the repair and maintenance time;
3, reduced maintenance cost.
