Abstract

A kind of equal thick roll sieve clearing apparatus, comprise fishback, fixed mount, wherein, three broach are arranged at described fishback top, on described fixed mount, be laterally evenly equipped with unthreaded hole, described fishback bottom have four with fixed mount on the unthreaded hole of unthreaded hole corresponding matching, there is triangle reinforcement in broach front on described fishback, described fixed mount two ends are connected with roller picker shell, described fishback bottom is connected with fixed mount, between the broach on described fishback and sieve on roller picker, coordinates; The chamfered surface of the triangle reinforcement on described broach has build-up wear-resistant layer, the beneficial effects of the utility model are, install sweeper additional and can clear up at any time the long-pending coal between roller screen axle and sieve, guarantee exerting oneself of equal thick roll sieve, effectively avoid causing coal breaker to amass coal phenomenon, the long-pending coal effect of cleaning is remarkable, and simple in structure, durable, is easy to installation, maintenance, replacing.

Description

Equal thick roll sieve clearing apparatus

Technical field

This practical power plant soot conveying technology that relates to, especially a kind of equal thick roll sieve clearing apparatus.

Background technology

Due to coal market pressure, Thermal Power Enterprises ature of coal amount used changes thereupon, and Thermal Power Enterprises can only take mixed coal combustion to reduce costs.Quality decline, chad increases, and causes to original coal handling plant many inapplicable.Easily long-pending coal between the gap of roller picker sieve, through long-play, amasss coal by the gap smaller between two sieve axles, the reduction of exerting oneself of equal thick roll sieve, and the effect of screening coal reduces, and the coal amount that enters coal breaker increases, and often causes the full coal phenomenon of coal breaker.Particularly winter, broken coal also easily freezes, and the long-pending coal of roller picker sieve is removed very difficult, and clear coal operation is more dangerous, affects unit safety operation.

Summary of the invention

In order to overcome long-pending coal between two sieves of roller picker, affect the deficiency of exerting oneself of equal thick roll sieve, for guaranteeing the stable operation of coal breaker, the utility model provides a kind of equal thick roll sieve clearing apparatus, this equal thick roll sieve clearing apparatus has taked to use the form of broach, not only simple in structure, be easy to install, and reached and effectively avoid causing coal breaker amass coal phenomenon, the object of coal is amassed in cleaning.

The technical scheme of the invention for solving the technical problem comprises fishback, fixed mount, wherein, three broach are arranged at described fishback top, on described fixed mount, be laterally evenly equipped with unthreaded hole, described fishback bottom have four with fixed mount on the unthreaded hole of unthreaded hole corresponding matching, there is triangle reinforcement in broach front on described fishback, described fixed mount two ends are connected with roller picker shell, described fishback bottom is connected with fixed mount, between the broach on described fishback and sieve on roller screen axle, coordinates;

The chamfered surface of the triangle reinforcement on described broach has build-up wear-resistant layer.

The beneficial effects of the utility model are, end employing huge cross-section design due to fishback top broach, make it can be consistent with the fit clearance of roller screen axle, the triangle reinforcement on fishback have strengthened the intensity of broach, and broach is not yielding, clearing apparatus can be cleared up the long-pending coal between roller screen axle and sieve at any time, guarantee exerting oneself of equal thick roll sieve, effectively avoid causing coal breaker to amass coal phenomenon, the long-pending coal effect of cleaning is remarkable, and simple in structure, durable, be easy to installation, maintenance, replacing.

Accompanying drawing explanation:

In conjunction with drawing, the utility model is further illustrated:

Fig. 1. be the utility model installation diagram;

Fig. 2. be the side view of the utility model Fig. 1;

Fig. 3. be the structure chart of the utility model fishback.

The specific embodiment:

The concrete mode of implementing of the utility model is, comprise fishback 6, fixed mount 4, wherein, with reference to Fig. 1, Fig. 2, three broach 8 are arranged at described fishback 6 tops, on described fixed mount 4, be laterally evenly equipped with unthreaded hole 5, described fishback 6 bottoms have four with fixed mount 4 on the unthreaded hole 10 of unthreaded hole 5 corresponding matching, there is triangle reinforcement 7 in broach 8 fronts on described fishback 6, described fixed mount 4 two ends are connected with roller picker shell 3, described fishback 6 bottoms are connected with fixed mount 4, broach 8 on described fishback 6 coordinates with 2 of sieves on roller screen axle 1, remove the falling material being mingled with in roller screen axle 1 and sieve 2, with reference to Fig. 3, the chamfered surface of the triangle reinforcement 7 on described broach 8 has build-up wear-resistant layer 9, strengthens holding capacity and the wearability of two roller screen axles 1 and 2 materials that drop of sieve, the utility model can be according to a plurality of fishbacks 6 of length axially-aligned that are mated the roller screen axle 1 of use.

Claims
