Abstract
The utility model relates to an automatic ball guiding device of a steel ball coal grinding machine, which is characterized by comprising a conical pipe, ball collecting grooves and a ball collecting pipe, wherein the conical pipe is connected with an inlet of the coal grinding machine through a support, the small diameter end of the conical pipe is connected with the ball collecting pipe, the ball collecting grooves are symmetrically arranged on the ball collecting pipe along the radial direction, ball outlet holes are arranged on the wall of the ball collecting pipe corresponding to the ball meeting sides of the ball collecting grooves, and partition plates for separating the ball outlet holes are arranged on the ball collecting pipe. The number of the ball collecting grooves is 1-2 pairs. Compared with the prior art, the automatic ball guiding device of the steel ball coal grinding machine has the benefits that, when a cylinder body of the steel ball coal grinding machine rotates normally, steel balls can fall into a ball guiding groove along with the rotation of the coal grinding machine and are discharged along the conical pipe, thereby greatly reducing the maintenance workload and the labor intensity.
Description
Technical field
The utility model relates to the low speed coal mill field, relates in particular to a kind of low speed coal mill and leads ball device automatically.
Background technology
Low speed coal mill is the main equipment of thermal power plant coal dust preparation system; Its effect is with coal cinder drying, the fragmentation of certain size and grinds into coal dust for giving boiler combustion; Low speed coal mill is adopted by domestic and international thermal power plant in a large number, also is applicable to pulverized coal preparation systems such as cement industry, metallurgical industry, chemical industry, sugar industry simultaneously.During the low speed coal mill internal overhaul, need steel ball is drawn out in cylindrical shell, the steel ball that more renews is perhaps changed lining tile in the cylindrical shell, and this labor intensity is big, and hazards are many, can only manually-operated because the space is little, can't use plant equipment.
Summary of the invention
The purpose of the utility model provides a kind of low speed coal mill and leads ball device automatically, realizes emptying automatically steel ball in the coal pulverizer cylindrical shell, reduces labour intensity.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
Low speed coal mill is led ball device automatically; Comprise conical pipe, collection ball groove and collection bulb; Conical pipe is connected with the coal pulverizer inlet through support, and the conical pipe miner diameter end is connected with the collection bulb, and collection ball groove radially is symmetricly set on the collection bulb; The last corresponding collection ball groove of Ji Qiuguanbi is met the ball side and is provided with spherical cavity, and said collection bulb is provided with the dividing plate that spherical cavity is separated.
Said collection ball groove quantity is 1～2 pair.
Prior art is compared, and the beneficial effect of the utility model is: normal rotating steel ball milling coal machine drum body, steel ball can be discharged along conical pipe along with coal pulverizer rotates to drop in the collection ball groove automatically, thereby reduces maintenance workload and labour intensity greatly.

The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model:
See Fig. 1, Fig. 2, Fig. 3, Fig. 4; Be that the utility model low speed coal mill is led ball device example structure sketch map automatically; This device is arranged on the coal pulverizer porch, and conical pipe 1 is connected with coal pulverizer inlet 6 through support 10, comprises conical pipe 1, collection ball groove 2 and collection bulb 3; Conical pipe 1 miner diameter end is connected with collection bulb 3; A pair of collection ball groove 2 radially is symmetricly set on the collection bulb 3, and corresponding collection ball groove 2 is met the ball side and is provided with spherical cavity 4 on collection bulb 3 walls, and collection bulb 3 is provided with the dividing plate 5 that spherical cavity 4 is separated.
During the coal pulverizer operate as normal, coal cinder is sent into from coal pulverizer inlet 6, cylindrical shell 7 rotations; 8 frictions of coal cinder and steel ball are discharged from coal pulverizer outlet 9 after clashing into into powder; When overhauling out ball, this device is arranged on coal pulverizer 6 places that enter the mouth, rotary barrel 7; Steel ball 8 drops on automatically in the collection ball groove 2 and discharges along conical pipe 1, need not manual work and draws operation clearly.
Claims (2)
1. low speed coal mill is led ball device automatically; It is characterized in that comprise conical pipe, collection ball groove and collection bulb, conical pipe is connected with the coal pulverizer inlet through support; The conical pipe miner diameter end is connected with the collection bulb; Collection ball groove radially is symmetricly set on the collection bulb, and the last corresponding collection ball groove of Ji Qiuguanbi is met the ball side and is provided with spherical cavity, and said collection bulb is provided with the dividing plate that spherical cavity is separated.
