Abstract
The utility model relates to a tool for a coal pulverizer, particularly to a ball selective tool of a cylinder steel ball pulverizer. The tool comprises a flare pipe, an elbow, a flange, and a connecting stub. The elbow and the connecting stub are in the hollow structure; the small end diameter of the flare pipe is connected with one end of the elbow; the other end of the elbow is connected with the connecting stub through the flange; the other end of the connecting stub is connected with a cylinder grid plate. Compared with the prior art, the art adopted by the utility model is characterized in that the connecting stub is welded on an inner end liner plate of a pulverizer cylinder body at the entrance of the coal pulverizer; small steel balls and broken iron blocks in the pulverizer cylinder body will pass through the cylinder gird plate so as to connecting stub, and then passes through the elbow, the flare pipe and flow out of the pulverizer cylinder body in sequence after the coal pulverizer is started, so that the labor intensity is reduced and the working efficiency is improved.
Description
Technical field:
The utility model relates to a kind of coal-grinding machine tool, a kind of specifically barrel-shaped steel ball mill instrument of choosing shuttles.
Background technology:
Steel ball in the coal pulverizer in the course of the work, its diameter of wearing and tearing constantly reduces continuously, the too small steel ball of diameter grinds the ability drop of coal dust, coal is in the process of process of exploiting and accumulating, having metal sneaks into, the ironware that enters coal pulverizer is different, the powder process ability drop, increase coal pulverizer power consumption, therefore to regularly select steel ball, steel ball that diameter is too small and irregular irony fragment are picked out, after treating that coal pulverizer stops, with artificial hand selection's method bead and bushel iron piece are chosen, in the coal pulverizer of more qualified steel ball being packed into, so not only increased working strength of workers but also prolonged maintenance duration.
Summary of the invention:
Goal of the invention of the present utility model is to provide the deficiency that overcomes background technology and a kind of barrel-shaped steel ball mill that labor strength improves work efficiency instrument of choosing shuttles that reduces is provided.
The utility model adopts following technical scheme:
A kind of barrel-shaped steel ball mill instrument of choosing shuttles, comprise oviduct, elbow, flange, connection joint, described elbow, connection joint all are hollow core structures, the end diameter of described oviduct is connected with elbow, the other end of this elbow by flange be connected joint and connect, this other end that connects joint is connected with the tubular grate plate.
The utility model of employing technique scheme compared with prior art, to connect joint at the inlet of coal pulverizer is welded on the interior aside-liner of coal pulverizer cylindrical shell, start coal pulverizer then, small ball in the coal pulverizer cylindrical shell will enter by the tubular grate plate with the bushel iron piece and be connected joint, flow to outside the cylindrical shell of coal pulverizer by elbow and oviduct successively, have the effect that reduces labor strength, improves work efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with drawings and Examples in detail the utility model is described in detail:
A kind of barrel-shaped steel ball mill instrument of choosing shuttles, referring to accompanying drawing 1, by oviduct 1, elbow 2, flange 3, connect joint 4, tubular grate plate 5 is formed.
Elbow 2 be connected joint and 4 all be hollow core structures, the end diameter of oviduct 1 is connected with elbow 2, the other end of elbow 2 saves 4 connections by flange 3 with being connected, connection saves 4 the other end and is connected with tubular grate plate 5.
During use the feed end of coal pulverizer is pulled down, to connect joint 4 at the coal pulverizer inlet is welded on the interior aside-liner of barrel-shaped steel ball mill, the bottom is held with channel-section steel and is fixed, come off when avoiding rotating, oviduct 1 is welded on the coal pulverizer spiral tube, start coal pulverizer then, small ball in the spiral tube and bushel iron piece will by tubular grate plate 5 enter is connected save 4 after, flow to outside the coal pulverizer cylindrical shell by elbow 2 and oviduct 1 successively, the major diameter steel ball can not enter tubular grate plate 5 and stay in the coal pulverizer cylindrical shell, thereby reaches the purpose of choosing shuttles.
