Abstract
The invention discloses a gangue filling pneumatic conveying system. The gangue filling pneumatic conveying system comprises a Roots blower, a rotating feeding machine, an accelerating chamber and a wear-resisting conveying pipeline which are connected with each other, wherein an air inlet which is connected with the Roots blower is arranged on one side of the accelerating chamber; a discharge port which is connected with the wear-resisting conveying pipeline is arranged on the other side of the accelerating chamber; a feeding port which is connected with the rotating feeding machine is arranged at the top; and the wear-resisting conveying pipeline is a graded type pipeline, namely, the inner diameter of the pipeline is gradually increased from head to tail. The strong wind power is supplied by the Roots blower; the continuous quantitative feeding of materials is realized by the rotating feeding machine; and the materials are conveyed to a collecting cabin at an end of an operating surface through the wear-resisting conveying pipeline with the gradually increased inner diameter, thereby achieving the purpose of long-distance conveying.
Description
Technical field
The present invention relates to the waste filling system of underground mine use, induction system is simply and easily installed, arranged to especially a kind of suitable long distances, equipment.
Background technology
China is coal big country, and high strength exploitation for many years causes the gangue bulk deposition; The landed property resource, goaf and subsidence area are also in continuous expansion, in recent years simultaneously; Coal industry is development and application gangue refill technology competitively, the gangue backfilling goaf, not only can protect farmland; And can utilize the mining industry solid waste to greatest extent, keep mining industry production sustainable and stable development.Through continuous development in the past few years, mining with stowing has new progress again improving and improving on the basis of prior art, at aspects such as casting resin preparation, conveying technology, filler exploitation and stoping-and-filling technologies significant progress has been arranged all.
But whole on the whole filling process origin material equipment, conveying equipment, work plane stowage unit are accomplished.Wherein, supplied materials equipment is the elementary delivery phase of whole filling system, and conveying equipment is the core of whole filling system.
The advanced conveying equipment of coal mine retrofilling system is to use conveying worm to cooperate the wind-force conveying to reach the purpose to the work plane convey materials at present.Advantages such as that conveying worm has is simple in structure, cross sectional dimensions is little, good seal performance, easy-to-operate and low cost of manufacture.But conveying worm also has the shortcoming of himself, and its shortcoming is that component wear is serious, conveying capacity is lower, and consumed power is big, and fed distance is short, makes whole wind-force induction system also not reach good result of use.
Summary of the invention
For overcoming the above-mentioned deficiency of prior art, the purpose of this invention is to provide a kind of ability and realize long fed distance, waste filling air-transport system is simply and easily installed and arranged to equipment.
For achieving the above object; The technical scheme that the present invention takes is: it is connected to form by roots blower, rotary feeder, accelerating chamber and wear resistant conveying pipe road; Described accelerating chamber one side is provided with the air intake that is connected with roots blower; Opposite side is provided with the discharging opening that is connected with abrasion-proof pipe, and end face is provided with the charging aperture that is connected with rotary feeder; Described abrasion-proof pipe is the stagewise pipeline, i.e. the internal diameter of the pipeline overstriking gradually that starts anew is until end.
Classification abrasion-proof pipe action principle of the present invention is: concerning single caliber system; After the initial velocity of air is confirmed; Along with the pressure decline of pipeline, air produces and expands, and the respective air transporting velocity constantly increases; Reach maximum value to end of line, the wearing and tearing of pipeline second half section than preceding half section serious many.For the system of classification caliber, through increasing caliber step by step, can be controlled at the air transporting velocity in the optimum range at streamwise, the classification position guarantees after the classification caliber increases this place's air velocity to be dropped to below the necessary numerical value of convey materials; The classification pipeline not only is controlled at the air transporting velocity in the low scope, but also greatly reduces required supply gas pressure.
The present invention provides powerful pneumatic power by roots blower, and rotary feeder is realized material feed continuously and quantitatively, and the wear-resisting pipeline force feed that in accelerating chamber, the material edge is increased internal diameter step by step reaches the purpose of remote conveying to the collecting bin of face end.The rotary feeder discharge is smooth in this system, good seal performance, and the wearing and tearing of stagewise abrasion-proof pipe reduce long service life.
Description of drawings
Fig. 1 is a sketch map of the present invention.
Marginal data: 1-roots blower; 2-swivel feeding machine; The 3-accelerating chamber; 4-head level abrasion-proof pipe; 5-final stage abrasion-proof pipe.
The specific embodiment
Accompanying drawing is one embodiment of the present of invention, specifies present embodiment below in conjunction with accompanying drawing.
As shown in Figure 1; Waste filling air-transport system roots blower of the present invention 1, rotary feeder 2, accelerating chamber 3 and wear resistant conveying pipe road connect to form; Described accelerating chamber 3 one sides are provided with the air intake that is connected with roots blower 1; Opposite side is provided with the discharging opening that is connected with abrasion-proof pipe, and end face is provided with the charging aperture that is connected with rotary feeder; Described abrasion-proof pipe is the stagewise pipeline, and the internal diameter of the pipeline overstriking gradually that starts anew until end, also can be found out from figure, and the internal diameter of head level abrasion-proof pipe 4 is less than the internal diameter of final stage abrasion-proof pipe 5.
