Adjustable oblique coaling double-furnace sleeve type device

Abstract

The invention discloses an adjustable oblique coaling double-furnace sleeve type device which comprises a cross beam. Bases are arranged on the left side and the right side of the cross beam, and theinner walls of the bases are connected with the outer wall of the cross beam. A motor base is arranged on the upper surface of the cross beam, and the lower surface of the motor base is connected withthe upper surface of the cross beam. A motor is arranged on the upper surface of the motor base, and the lower surface of the motor is connected with the upper surface of the motor base. A connectingplate is arranged on the left side of the base. A box cooperates with supporting legs, and therefore connection of the motor and a fan is more stable through the box. All the assemblies can be fixedinto the box, and all the assemblies in the box operate more stably. By means of the box, the situation that an assembly in a conveying belt generates noise to influence work of an operator can be effectively avoided, and therefore the defect that a traditional adjustable oblique coaling double-furnace sleeve type device is unstable in connection and high in noise is overcome.

Description

technical field [0001] The invention relates to the technical field of industrial machinery, in particular to an adjustable double-furnace casing device for coal feeding on an incline. Background technique [0002] In blast furnace ironmaking, cheap pulverized coal is injected instead of expensive coke as fuel to reduce the cost of pig iron. The process of producing pulverized coal for blast furnace injection is to use the overhead crane to grab the raw coal from the coal yard to the coal blending bunker, and after blending The disc coal feeder under the bunker brings the raw coal to the belt, and then transports it to the raw coal bunker. The raw coal in the raw coal bunker enters the coal mill through the coal feeder for grinding, and the qualified pulverized coal is used for the blast furnace. The disc coal feeder under the coal bunker brings the raw coal to the belt through the rotation of the disc on it, and then transports it to the raw coal bunker by the belt. The amo...

[0002] In blast furnace ironmaking, cheap pulverized coal is injected instead of expensive coke as fuel to reduce the cost of pig iron. The process of producing pulverized coal for blast furnace injection is to use the overhead crane to grab the raw coal from the coal yard to the coal blending bunker, and after blending The disc coal feeder under the bunker brings the raw coal to the belt, and then transports it to the raw coal bunker. The raw coal in the raw coal bunker enters the coal mill through the coal feeder for grinding, and the qualified pulverized coal is used for the blast furnace. The disc coal feeder under the coal bunker brings the raw coal to the belt through the rotation of the disc on it, and then transports it to the raw coal bunker by the belt. The amount of coal feeding is adjusted by the rotating speed of the disc. In the prior art For example, the invention patent with application number 201020263630.5 includes a turntable on which at least two coal-discharging tendons protruding from the upper surface of the turntable are fixed. The coal-discharging rebar is selected as threaded steel, and the diameter of the rebar is 5-20mm. The rebar is welded on the turntable. One or more of steel pipe, steel bar, steel wire, or threaded steel. Although the structure of this invention is simple, there are many deficiencies and defects. In the existing equipment, the design of the disc has defects. When the coal feeding speed is too fast In this case, the coal will directly overflow and fall from the edge of the disc, losing the adjustment function. In view of these situations, in order to avoid the above-mentioned technical problems, it is necessary to provide an adjustable double-furnace casing device for slanting upward coal feeding to overcome the existing said defects in the technology
