Description
Technical field
The present invention relates to a kind of feeder, specifically to the improvement of traditional round taper or hyperbola coal bunker feeder.
Background technology
The version of storage bin mostly is cylinder or the rectangular structure that straight section is adopted in the upper end at present, the lower end is inverted pyramidal structures, because conical section bulkhead and horizontal surface angle of cut angle require to be not less than 60 °, the space that the short transverse of traditional coal bunker is adjustable is very little, and overall height is very high.The discharge way of storage bin mostly is the gravity type boat davit discharging, because the storage bin lower end is reverse taper, after use after a while, putty phenomenon in various degree all appears, the technology of current this difficult problem of solution putty comprises following several mode: the first, by in reverse taper inside the hydraulic pressure dredger being installed, after the putty phenomenon occurs, start the hydraulic pressure dredger material in the cone is dredged, improve the flowing power of material in cone.The second, by inlay corrosion-resistant steel or high polyvinyl chloride liner plate in the inside of reverse taper, reduce the friction force between material and the reverse taper inside face, improve the flowing power of material in cone with this.Three, by the outside face at reverse taper the devices such as vibrator, air bubble are installed, Vibration on Start-up device, air cannon device after the putty phenomenon occurs are by vibrating the material in the cone or the mode of suddenly explosion is improved the flowing power of material in cone.
In conjunction with real condition of service, for three kinds of different modes of above-mentioned storage bin and solution putty, have following shortcoming: storage bin itself has excessive height, space availability ratio is low, investment is large, material easily stops up; Because the coal bunker outlet size is too little with respect to the coal bunker diameter, be subjected to coal seam pressure too large, tradition coal bunker ubiquity chute blockage phenomenon, three kinds of modes that solve putty all belong to the compensating measure, different materials is existed the phenomenons such as bad adaptability, DeGrain, can't fundamentally solve the storage bin excessive height, space availability ratio is low, investment is large, the easy difficult problems such as obstruction of material.
Summary of the invention
Goal of the invention: the objective of the invention is in order to overcome deficiency of the prior art, a kind of saving bunker bay volume is provided, chute blockage not reduces the novel flat-bottom coal bunker of main building comprehensive cost.
