Abstract
The utility model discloses a waste filling pneumatic conveying system which comprises a roots blower, a rotary feeder, an accelerating chamber and an abrasion resistant conveying pipeline. One side of the accelerating chamber is provided with an air inlet which is connected with the roots blower, the other side of the accelerating chamber is provided with a discharging port which is connected with the abrasion resistant conveying pipeline, and the top surface of the accelerating chamber is provided with a feeding port which is connected with the rotary feeder; and the abrasion resistant conveying pipeline is a stagewise pipeline, and namely, the inner diameter of the pipeline gradually thickens from the head to the tail end. According to the waste filling pneumatic conveying system, a strong wind force is provided by the roots blower, materials are continuously and quantificationally fed through the rotary feeder, and the materials are fed to a collecting bin arranged at the end of a working surface under the pressure along the abrasion resistant pipeline with the inner diameter stepwise increasing in the accelerating chamber to achieve the purpose of long-distance conveying.
Description
Technical field
The utility model relates to the waste filling system of underground mine use, and delivery 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, compaction material exploitation and stoping-and-filling technologies significant progress has been arranged all.
But whole on the whole filling process origin material equipment, load transfer device, driving surface stowage unit are accomplished.Wherein, supplied materials equipment is the elementary delivery phase of whole filling system, and load transfer device is the core of whole filling system.
The advanced load transfer device of coal mine retrofilling system is to use conveyor screw to cooperate the wind-force conveying to reach the purpose to the driving surface convey materials at present.Advantages such as that conveyor screw has is simple in structure, cross sectional dimensions is little, good seal performance, easy-to-operate and low cost of manufacture.But conveyor screw also has the shortcoming of himself, and its shortcoming is that component wear is serious, operational throughput is lower, and consumed power is big, and fed distance is short, makes the also good result of use of out of reach of whole wind-force delivery system.
Summary of the invention
For overcoming the above-mentioned deficiency of prior art, the purpose of the utility model provides a kind of ability and realizes long fed distance, and waste filling air-transport system is simply and easily installed and arranged to equipment.
For achieving the above object; The technical scheme that the utility model is taked 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 and roots blower bonded assembly ventilation inlet; Opposite side is provided with and abrasion-proof pipe bonded assembly discharging opening, and end face is provided with and rotary feeder bonded assembly inlet point; Described abrasion-proof pipe is the stagewise pipeline, i.e. the internal diameter of the pipeline overstriking gradually that starts anew is until end.
The utility model classification abrasion-proof pipe action principle is: concerning single caliber system; After the rate of onset of air is confirmed; Along with the pressure decay of pipeline, air produces and expands, and the respective air delivery speed constantly increases; Reach maxim 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 delivery speed 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 delivery speed in the low scope, but also greatly reduces required supply gas pressure.
The utility model 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 the utility model scheme drawing.
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 an embodiment of the utility model, specifies present embodiment below in conjunction with accompanying drawing.
As shown in Figure 1; Waste filling air-transport system roots blower 1, rotary feeder 2, accelerating chamber 3 and the wear resistant conveying pipe road of the utility model connect to form; Described accelerating chamber 3 one sides are provided with and roots blower 1 bonded assembly ventilation inlet; Opposite side is provided with and abrasion-proof pipe bonded assembly discharging opening, and end face is provided with and rotary feeder bonded assembly inlet point; 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.
