Description
Technical field
The present invention relates to a kind of coal breakage bucket blocking preventing and dredger, be applicable to that the former coal hopper in power plant and other have the occasion of a large amount of Flow of Goods and Materials.
Background technology
Thermal power plant's raw coal material-falling hopper is that coal handling system is carried coal-fired visual plant to boiler combustion system.Its planform is basic identical, and top is cylindrical, and the bottom is conical.Suitable for reading big, following young, charging suitable for reading, raw coal falls by deadweight from top to bottom.The following raw coal that falls behind enters coal mill by feeder, finally delivers to combustion chamber.In actual moving process, the blanking blockage problem that this equipment ubiquity is serious.After stopping up, can bring by coal bunker operation to shut down or waste serious consequences such as heavy oil.
Usually, the power station attendant uses sledgehammer to pound the outer wall of material blanking tube suddenly, makes the loosening whereabouts of material of obstruction.Yet this original method can make the blanking barrel deformed damaged very soon.At present, producer is also arranged at this problem, install air bubble additional on material blanking tube, utilize air bubble to the material that the stops up mediation of exploding, this method can produce great noise, causes airborne dust, also has potential dangerous hidden danger.
Summary of the invention
The problem that the present invention need solve provides a kind of unpowered self-driven type anti-block apparatus of power plant feed coal funnel, realizes the pre-anti-clogging of power plant feed coal funnel and dredges two kinds of functions of obstruction.This device has designed a kind of unpowered self-driven type anti-block apparatus that the block clearing bar is moved up and down fully analyzing on the basis of coal bunker blanking obstruction, is installed on coal breakage bucket inside.
The technical scheme that the present invention solves its technical matters employing is:
A kind of unpowered self-driven type coal hopper anti-blocking device comprises: protecting against shock cap assembly, last fixed link assembly, oscillating bar assembly, connecting rod assembly, parallel-crank mechanism;
First adapter sleeve of last fixed link assembly is connected by safety washer, screw bolt and nut with first sleeve, forms revolute pair; Last fixed link assembly connects firmly on the coal breakage headwall by upper mounted plate;
One end of first fork on the oscillating bar assembly passes trepanning, and welding connects firmly; Second sleeve on the oscillating bar assembly is connected by safety washer, screw bolt and nut with second adapter sleeve on the connecting rod assembly, forms revolute pair; The 3rd sleeve on the connecting rod assembly is connected by safety washer, screw bolt and nut with the 3rd adapter sleeve, forms revolute pair;
Parallel-crank mechanism connects firmly on the coal breakage headwall by bottom plate;
When coal cinder when coal breakage bucket top falls, impact cone-shaped stainless steel erosion control cap, the protecting against shock cap assembly is by oscillating bar assembly and connecting rod assembly, the block clearing bar that drives on the parallel-crank mechanism moves up and down, and realizes the pre-anti-clogging of coal breakage bucket and dredges obstruction.
The beneficial effect that the present invention had:
Utilize the simple and easy characteristic of connecting rod mechanism, provide a kind of and can realize pre-anti-clogging and dredge the unpowered self-driven type coal hopper anti-blocking device that stops up two kinds of functions.This anti-block apparatus can make the block clearing bar move up and down, and the coal charge of the obstruction of cleaning and mediation is installed on coal bunker inside.Mechanism all places cone-shaped stainless steel protecting against shock cap bottom, prevents that effectively blanking from impacting the destruction to mechanism kinematic pairs.This device is with pre-anti-clogging and dredge and stop up two kinds of functions and carry out combination, is a kind of novel power plant coal handling system accessory machinery.
