Silo, silo feeding method and concrete mixing plant

Abstract

The invention relates to the technical field of silo feeding, and discloses a silo and a silo feeding method. The silo comprises a material containing cavity defined by the silo wall, wherein a cyclone feeding cylinder is arranged on the silo wall, the cyclone feeding cylinder comprises a feeding channel, a feeding inlet at one end of the feeding channel communicates with the outside of the silo,a feeding outlet at the other end of the feeding channel communicates with the material containing cavity, and the structure of the feeding channel is set to achieve the effect that a material conveyed by the wind power moves downwards in the circumferential direction of the feeding channel and enters the material containing cavity in the circumferential direction from the feeding outlet. Due to the fact that the powder material moves downwards in the circumferential direction of the feeding channel, the initial speed of the powder material when the powder material enters the silo is reduced,then the amount of dust generated in the powder material falling process is reduced, and then the dust removal pressure of the silo is further reduced, such as the dust removal pressure of a dust remover arranged on the silo.

Description

technical field [0001] The invention relates to the technical field of silo feeding, in particular to a silo, a silo feeding method and a concrete mixing device. Background technique [0002] The existing concrete mixing plant (building) is equipped with a silo, and the powder is stored in the silo through a powder tanker through a feed pipe. When the mixing station uses powder, the powder in the silo passes through a screw conveyor or a wind The trough is conveyed into the silo of the mixing main building. [0003] The existing silo adopts a 90-degree right-angle feeding pipe design, that is, the vertical pipe extends upwards to the top of the silo, and then connects with a horizontal pipe, and the horizontal pipe is connected to the downward vertical pipe to enter the silo. In this way, the powder The material needs to enter the silo through two right-angle turns, then spread out to both sides along the outlet of the feed pipe, and accumulate continuously at the bottom of...

AI Technical Summary

Problems solved by technology

[0004] The feeding method of the current silo has certain deficiencies. For example, the powder needs to enter the silo through two 90-degree corners. On the one hand, the powder tanker also needs more feed air pressure, resulting in waste; in addition, when the powder enters the silo vertically, it has a certain initial velocity when entering the silo, coupled with the effect of gravity acceleration during the descent process, resulting in the powder falling speed Soon, the time is very short, and a large amount of dust will be generated during the process of falling and accumulating. A large amount of dust requires a relatively high dust removal capacity of the dust collector
