SU962663A2 - Loading device for pneumatic transport of filling-up material - Google Patents

Description

The invention relates to the mining industry and can be used in the development of minerals with the laying of a goaf. According to the main auth. If 61761 a loading device for pneumatic transport of a backfill material is known that contains an inclined bunker with partitions in its upper part, transport pneumatic pipes, an ejector, a vibrator and a bellows will accept partitions made in the form of gate valves with canopies attached to them installed with the possibility of moving perpendicular to the flow of material , at the same time the hopper-feeder is connected to the base by means of elastic connections, and with the transport pneumatic tubing by means of a bellows. The disadvantages of the known device are the increased expenditure of energy on the creation of vibrations. This is due to the need to overcome the axial force in the bellows, which is directed perpendicular to its cross section and perceived by elastic connections. The purpose of the invention is to reduce energy consumption for the creation of vibrations. The goal is achieved by the fact that the charging device for pneumatic transport of the backfill material is equipped with an additional bellows installed coaxially to the bellows mounted on the feed hopper; One end of which is fixed, the additional bellows cavities and the feed hopper communicate with each other, and the bellows are made with the same areas cross cross sections. The drawing shows the proposed device. The loading device includes an inclined feed hopper 1 connected by a bellows 2 with pneumatic pipes 3 and Aj between which the

The height remains constant and the specified degree of sealing of the transport pneumatic pipe 4. A continuous stream of material with a layer height determined by the position of the lower end of the gate moves to the loading point of the ejection chamber 5, where water 3 is drawn into the transport pneumatic pipe by an active stream of compressed air coming out of the pneumatic tube 4. The feed hopper is in a balanced state for any air pressure in the ejection chamber 5, since the axial force in the bellows 2 is balanced by the axial force in the additional “bellows 10. The proposed device can significantly reduce energy consumption and the creation of vibrations. • g The loading device for pneumo · * transport of filling material by ed. 1? 617614, characterized in that, in order to reduce energy consumption for creating vibrations, it is equipped with an additional bellows coaxially mounted to the bellows hopper, one end of which is fixed motionless, while the cavities of the additional bellows and hopper are interconnected and the bellows are made with the same areas of the passage cross-sections.
