Description
Technical field
The utility model belongs to coal conveying equipment field, blocks up protection system more specifically to a kind of anti-coal.
Background technique
Currently, the protection of coal handling system coal pipe coal blockage is radio frequency admittance pattern, it is installed below reversible deflector at coal spout,
Measuring cylinder is open obliquely.Fall about 0.8 meter -1.0 meters of length of the radio frequency admittance formula anti-clogging coal inductive switching feeler lever, the type induction
Element is affected by site environment, and gathering coal, which splashes down, to be touched on induction rod or induction rod product coal dust and can all equipment be caused to be missed
It is dynamic；On the other hand induction feeler lever is such as to encounter gathering coal and pound to fall in insertion coal spout, and feeler lever is easily damaged；Chute blockage protection simultaneously
Device cannot can not detect in time protective device reliability in thread test；Even if can not be dredged in time after monitoring chute blockage
Logical work can only join and stop corresponding belt, reduce coal handling system working efficiency.
In view of the above-mentioned problems, be also correspondingly improved, it is open such as Chinese Patent Application No. CN201620312349.3
Day is on April 14th, 2016, and which disclose the buffering anti-block apparatus for coal spout, including several settings are in coal spout
The chain of top, described chain one end are fixed on the shield above coal spout by the hook of elasticity, and the other end freely dangles,
The shock surface face conveyer belt that the chain is formed throws direction.The utility model is arranged to chain type stream buffering using chain
Anti-block apparatus carries out whole water conservancy diversion to the coal stream left by chain flexible, makes coal stream from unordered pendant using discrete principle
Fall the controllable landing process that is changed into, effective solution coal spout is easy the defect of chute blockage, reduces coal stream and conveys skin to junior
The impact of band, effective protection belt machine equipment, prevents coal dropping point from just not inducing belt deviation, while alleviating coal stream to coal spout
