Abstract
The utility model discloses a coal dropping device with an improved screw rod propeller. The coal dropping device comprises a material feeding and storing groove, a conveying pipeline, a motor, a speed reducer, an inner screw rod and a bearing, wherein the material feeding and storing groove is installed at the tail end of the conveying pipeline; the inner screw rod extends to the head end from the tail end of the conveying pipeline, and the inner screw rod is provided with rotary blades; the inner screw rod is connected with the speed reducer and the motor; the head end of the conveying pipeline is provided with a coal material dropping opening; the inner screw rod is divided into a rough-segmentation conveying section and a fine-segmentation conveying section; the rough-segmentation conveying section is arranged at the tail section of the inner screw rod, and the fine-segmentation conveying section is arranged at the front section of the inner screw rod; and a distance between the rotary blades of the fine segmentation conveying section is 1/3-2/3 that of the rough-segmentation conveying section. By dividing the inner screw rod into the rough-segmentation conveying section and the fine-segmentation conveying section, the rotary blades of the fine-segmentation conveying section are more dense than those of the rough-segmentation conveying section so that the space between the rotary blades of the fine-segmentation conveying section is smaller; when the sand coal is transported to the fine-segmentation conveying section at the tail end, the sand coal amount is uniform, and the coal drops off continuously, so that the coal powder of a fine grinding machine can be stably, uniformly and quantitatively sprayed into a hearth to reach the best use efficiency.
Description
Technical field
The utility model relates to coal charge load transfer device technical field, is specifically related to a kind of buster.
Background technology
The principle of buster is the driving through motor; Inner screw ceaselessly rotates; Be with rotating blade to gyrate; Thereby can the sand coal in the charging stock chest constantly be transferred out from delivery duct, and fall from blanking port, the operational throughput of sand coal can be adjusted through the rotative speed of regulating inner screw.The product that sand coal is a raw coal after kibbler grinds, size is like the uniform state as the fine sand.It is a line from the beginning to the end that the tradition buster generally is designed to the rotating blade on the screw rod (screw thread), and the spacing between the rotating blade is big and spacing is identical.When the sand coal of carrying on the screw rod falls into atomizer mill; Because the spacing of rotating blade is big and identical, cause the coal breakage of sand coal discountinuity one top one top, make the coal breakage amount inhomogeneous, discontinuous; Cause the coal dust spray volume of atomizer mill also discontinuous, unstable, inhomogeneous, influence the service efficiency of equipment.
The utility model content
To the defective of prior art, the technical matters that the utility model will solve provide a kind of coal breakage evenly, the buster of connection, quantitative improvement worm propeller.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of buster that improves worm propeller; Comprise charging stock chest, delivery duct, motor, reductor, inner screw and bearing, delivery duct is an incline structure, and its head end is high, tail end is low; The charging stock chest is installed in the delivery duct tail end, and the bottom opening of charging stock chest is communicated with the inlet of delivery duct; Inner screw is installed in the delivery duct, and its tail end from delivery duct extends to head end always, and the screw-shaped rotating blade is arranged on the inner screw; Inner screw connects reductor, and reductor connects motor, and motor and reductor are located at delivery duct head front; The delivery duct head end is provided with the coal charge blanking port; Whole buster is rack-mount, it is characterized in that: whole inner screw is divided into two sections of A and B, and the A section is the rough segmentation span line, and the B section is the segmentation span line, and the rough segmentation span line is positioned at the rear of inner screw, and the segmentation span line is positioned at the leading portion of inner screw; The spacing of segmentation span line rotating blade is less than the spacing of rough segmentation span line rotating blade.
Preferably, the spacing of said segmentation span line rotating blade is 1/3～2/3 of a rough segmentation span line rotating blade spacing.
Preferably, the length of said segmentation span line is 20～40cm.
The utility model is through making inner screw rough segmentation span line and segmentation span line, and the rotating blade of segmentation span line is closeer than rough segmentation span line, thereby spacing is littler; When sand coal is transferred to tail end segmentation span line; Not only the sand coal amount evenly but also be successive coal breakage, thereby the coal dust of atomizer mill can be stablized, spray in the burner hearth evenly, quantitatively, reach best service efficiency; The assurance entire equipment is worked continually and steadily, improves the work efficiency of equipment.
