Abstract
The utility model discloses a spiral coal feeder which comprises a horizontal cylinder. A discharging port is formed in the middle of the bottom of the cylinder, a first feeding port and a second feeding port is symmetrically formed in the surface of the cylinder by taking the discharging port as a center, a transmission shaft s arranged in the cylinder, spiral blades for conveying coal powder are arranged on the transmission shaft, the rotating direction of the spiral blades of the left half-section transmission shaft corresponding to the first feeding port is opposite to that of the spiral blades of the right half-section transmission shaft corresponding to the second feeding port, and a transmission device is connected on the transmission shaft at the end of the cylinder. The spiral coal feeder has the advantages that by the aid of double-feeding ports, working efficiency of the coal feeder can be improved, the rotating directions of the spiral blades on two sections of the same transmission shaft are opposite, so that the coal powder fed by two ends are oppositely conveyed and then discharged in a concentrated manner from the discharging port, and the spiral coal feeder is less in supporting facility, small in occupied space, easy to operate and lower in energy consumption.
Description
Technical field
The utility model belongs to powder conveying technical field, is specifically related to the pneumatic conveying of fine coal and the coal feeder of fuming furnace intermediate bin.
Background technology
In the industries such as the pneumatic conveying of powder is carried in modern cement strength, metallurgy, be widely used.But traditional feeder auxiliary facility is more, machine floor area is large, complicated operation, equipment are prone to fault, easily causes safety misadventure simultaneously.
Utility model content
Utility model object: the purpose of this utility model is to provide that a kind of auxiliary facility is few, operation cylinder just, screw-type coal distributor safe and reliable to operation.
Technical scheme: screw-type coal distributor described in the utility model, comprise horizontally disposed cylindrical shell, in the middle of this cylinder body bottom, be provided with feed opening, at drum surface, centered by this feed opening, be symmetrical arranged the first inlet point and the second inlet point, in cylindrical shell, be provided with transmission shaft, and on this transmission shaft, be provided for the helicallobe of pulverized coal conveying, contrary with the helicallobe hand of rotation on half section, right side transmission shaft corresponding to the second inlet point corresponding to the helicallobe on half section, the left side transmission shaft of the first inlet point, connection for transmission device on the transmission shaft of cylindrical shell end simultaneously.
Wherein, described the first inlet point, the second inlet point and feed opening are provided with for controlling the valve of coal amount.
Described transmission shaft is connected with driving device by coupler.
Be positioned at the transmission shaft at described cylindrical shell two ends by graphite packing_seal.
Described driving device is frequency modulation control motor or without Excitation Adjustment speed motor.
Beneficial effect: compared with prior art, its advantage is the utility model: this feeder adopts the charging simultaneously of two inlet points, can improve the work efficiency of feeder; Two sections of helicallobe hand of rotation on same transmission shaft are contrary, and the coal dust of two endfeeds is carried in opposite directions, then concentrate from feed opening discharging; This feeder auxiliary facility is few, occupation of land space is little, easily operation and energy consumption minimizing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, this feeder comprises horizontally disposed cylindrical shell 1, and cylindrical shell is the hollow steel pipe that wall thickness is greater than 8mm, this cylindrical shell 1 use supported on shelves, and the other end is fixed on bench board.Cylindrical shell is provided with feed opening 2 in the middle of 1 bottom, is symmetrical arranged the first inlet point 3 and the second inlet point 4 at drum surface centered by this feed opening.The first inlet point 3, the second inlet point 4 and feed opening 2 are provided with valve 7, for controlling the operational throughput of coal dust.It is the equalization of pressure in order to guarantee that transmission shaft 5 bears that inlet point is symmetrical arranged, and also multipair inlet point can be depending on the circumstances or the needs of the situation set.In cylindrical shell 1, be provided with transmission shaft 5, and on this transmission shaft 5, be provided for the helicallobe of pulverized coal conveying, contrary with the helicallobe hand of rotation on half section, right side transmission shaft corresponding to the second inlet point corresponding to the helicallobe on half section, the left side transmission shaft of the first inlet point, the coal dust of two endfeeds is carried in opposite directions, then concentrated from feed opening discharging.In order to guarantee the normal rotation of helicallobe, the distance of cylinder inboard wall and helicallobe outer end is greater than 0 and be less than 2.5mm.The transmission shaft at described cylindrical shell two ends is by graphite packing_seal.Simultaneously on the transmission shaft of cylindrical shell end by coupler connection for transmission device 6, this driving device 6 is frequency modulation control motor or without Excitation Adjustment speed motor, driving device 6, coupler and cylindrical shell end are all fixed on bench board.
Working process: the valve of first opening inlet point and feed opening, powder enters screw-type coal distributor cylindrical shell from the inlet point at two ends, the running of actuator drives transmission shaft, two sections of helicallobes, with transmission shaft synchronous rotary, are carried the powder in cylindrical shell collect to cylindrical shell centres by cylindrical shell two ends to enter feed opening.
