Abstract
The utility model relates to an automatic ball feeding machine matched with a steel ball coal mill, which is composed of an electric automatic control loop, a hydraulic control system, a material hopper, a ball locking device and a ball conveying tube. The electric automatic control loop is composed of a time relay, and the hydraulic control system comprises an oil tank, an oil pump, an electro-magnetic valve and an oil cylinder. The material hopper is communicated with the ball conveying tube. The ball locking device is arranged at the upper part of the point the ball conveying tube communicating with the material hopper, and the lower part of the point is provided with a push rod driven by an oil cylinder piston. The utility model can feed the steel ball for the coal mill automatically according to the set time and set ball feeding quantity, and the coal mill can always run at an optimal efficiency point.
Description
The utility model belongs to machinery manufacturing technology field, is specifically related to a kind of automatic pulping apparatus that cooperates low speed coal mill to use.
At present, low speed coal mill is widely applied in each thermal power plant of China.Because low speed coal mill is in operation process, the mutual collision that steel ball does not stop makes worn steel ball, accumulates over a long period, and the steel ball amount reduces in the coal-grinding machine barrel, cause the steel ball coefficient of fullness of coal pulverizer to reduce, thereby the abrasive dust amount reduces.For keeping the abrasive dust amount constant, be forced to prolong the running time of coal pulverizer, thereby caused waste of electric energy, up to now, the domestic machinery that does not also add steel ball to coal pulverizer regularly manually adds ball so each power plant still continues to use traditional artificial mode that regularly adds steel ball.This conventional method, not only labour intensity is big, and is also very dangerous.
The purpose of this utility model is a kind of automatic marble-feeder of development, adopts machinery to add steel ball, replaces artificial strong physical work, improves the efficient of coal pulverizer, eliminates hidden danger.
The utility model is by the electric automatic control loop, and hydraulic control system, hopper, lock ball device and the pipe of losing are formed.The electric automatic control loop comprises the automatic control loop that the motor and the time relay thereof constitute.Hydraulic control system comprises fuel tank, oil pump, electromagnetism back control valve, oil cylinder.Hopper communicates with the pipe of losing, and is provided with the lock ball device above lose pipe and the hopper place of communicating, and its underpart is provided with the push rod by oil cylinder piston driving.In the hopper steel ball by the top of deadweight arrival push rod.After machine obtains losing instruction, motor rotation, oil pump feed also forms pressure, and pressure oil enters the bottom of oil cylinder through electromagnetism back control valve, makes the piston of oil cylinder promote to move on the push rod, steel ball is pushed into the lock ball device and steel ball is pinned.The lock ball device sends signal, makes the back controller action, and oil cylinder base pressure oil enters fuel tank, and pressure oil enters the top of oil cylinder through electromagnetism back control valve, and oil cylinder piston is moved down, and push rod also moves down thereupon, sets back.This moment, steel ball by from the top that reenters push rod, was promptly finished a working cycles again.
