Description

A kind of loose Cleaning device for pipeline of telescopic folding strong stirring

Technical field

The utility model belongs to hopper storage bin and stops up the Removal Technology field.Be specifically related to that a kind of side cone feed bin, circular cone feed bin, hyperbola feed bin that is applicable to coal mining enterprise, thermal powerplant, Mineral Processing Enterprises, cement mill, coke-oven plant etc. is loose, the loose Cleaning device for pipeline of the telescopic folding strong stirring of broken arch, block clearing.

Background technology

The run coal bin of domestic thermal powerplant substantially all is that top is square or cylinder, the side of being, bottom cone, circular cone or hyp funnel structure.These funnel coal bunkers are all according to the long-pending shrinkage percentage of uniform cross section or the long-pending shrinkage percentage design of approximate uniform cross section, and mobile in the storehouse of coal is fast below being, toward above slower, present the bulk flow state.The generation of coal bunker blocking phenomenon has been alleviated in this design to a certain extent.But in actual use, be subjected to the impact of the factors such as raw coal kind, grain shape, water ratio, especially in rainy season, the raw coal water ratio increases, and cohesiveness strengthens, the flowing power variation, very easily form tubular flow in funnel bottom, when serious in addition the whole coal bunker knot arch that hardens cause disconnected coal.Unit is forced to throw oily load down operation, and economy reduces, and especially the boiler of blowing powder producing mode has increased the difficulty that burning is adjusted because Coal-fired capacity is unstable, often because adjusting the improper boiler flameout that causes, has caused larger loss to thermal power generation corporations.

The cutout of run coal bin chute blockage has a process that forms gradually.When raw coal dropped to lower hopper from top, the coal at bulkhead place stream produced larger friction drag owing to being subject to the extruding of coal seam deadweight with bulkhead and slows down gradually, and the speed of coal stream is the fastest at central part, and is slower near bulkhead; When resistance during greater than propulsive effort coal fail to be convened for lack of a quorum and stop to flow and then bonding being solidificated on the bulkhead, friction is developed by the friction of coal grain and bulkhead be the friction of flowing between coal grain and the coal grain, aggravated the process of the static curing of coal grain, the flow area of coal stream can reduce gradually, there is the material that is equivalent to the discharging opening size to be column in the coal bunker centre and moves to discharging opening, form tubular flow; When resistance increased to vertical net pressure above coal grain Gravitative Loads, coal stream was stagnated and is formed arch and stop up.

In sum, to harden in the quiet stagnant adhesion at bulkhead place be the basic reason that coal bunker forms tubular flow, the disconnected coal of knot arch to material.In order to address this problem, manufacturing enterprise has adopted a lot of ways, such as air bubble, up and down drawable loosening machine, revolving scraper, electric motor of shaker etc., the Expected Results of all failing to obtain are installed at warehouse.Air bubble is very little because of air disturbance force radiation scope, and face is solidified in the adhesion that often can not effectively destroy knot arch layer, even plays the secondary action of compacting knot arch layer; The drawable loosening machine is limited because of the zone of action up and down, the easy bridging accretion of rake teeth material resistance of motion, and easily be distorted, be out of shape, the defective such as fracture; Revolving scraper is limited because of structure design, can only act on limited zone, coal bunker outlet bottom; Electric motor of shaker is large because of warehouse, and rapping power is inadequate, does not bring into play the broken arch effect, and is but often larger at the raw coal aqueous ingredients after multiple spot is installed electric motor of shaker, is the coal slime shape, or during moist powdery, material can shake more real and more real, flows not smooth.Many power plant, mine, coke-oven plant but produce little effect after the cost huge fund installs these equipment, and coal bunker blocking happens occasionally.

Summary of the invention
