Feeding and dedusting device of powder

Abstract

The invention discloses a feeding and dedusting device of powder, which belongs to a device for preventing dirt or snoot from escaping. The feeding and dedusting device of powder is composed of a powder chamber, a cyclone separator, and a powder transportation distributer, wherein a guide rail is horizontally arranged at one side of the upper part of the powder chamber; a tractor crane is arranged on the guide rail; the powder transportation distributer is horizontally arranged on the powder chamber at the opposite side of the guide rail; more than one group of dispersing tanks are arranged below the powder transportation distributer and communicated with a pipeline of the powder transportation distributer; the pipeline of the powder chamber is connected with the cyclone separator; the other end of the cyclone separator is communicated with a fan; and more than one group of spiral conveyers and more than one group of powder elevators are longitudinally arranged are transversely arranged at the lower part inside the powder chamber. The feeding and dedusting device of powder disclosed by the invention is reasonable in structural design, and good in dust removal effect; the traditional three-stage dust removal is changed into one-stage dust removal; the flow is simplified; the construction cost of the device is reduced; and the entire device is scientific and reasonable in sequential operations of each link from front to back, so that the dust removal can achieve the maximal efficiency and benefit.

Description

technical field [0001] The invention belongs to a device for preventing dirt or smoke from escaping, in particular to a powder feeding and dedusting device. Background technique [0002] In the field of tertiary oil recovery in the late stage of oilfield exploitation, polymer flooding technology has been applied on a large scale, and has become an ideal oil displacement method for increasing and stabilizing oilfield production. Although it can greatly increase the recovery rate, the investment is large and the cost High, but at present, the injection stations of various configuration stations in the oil field, when using mechanical equipment to dissolve and mix the powder, usually use the open feeding method of the sky crane, which cannot guarantee the timeliness and continuity of the main material. A large amount of dust will be generated and the pollution will be serious. The staff have to be in direct contact with the dust, which seriously affects the health and is not h...

AI Technical Summary

Problems solved by technology

However, its structural design is unreasonable and its technical content is not high, which is reflected in the dust removal process, which is mainly realized by the three-stage dust removal method of the first-stage cyclone dust collector, the second-stage cyclone dust collector and the third-stage cyclone dust collector. High, and in the process of feed dust removal, the dust removal effect will vary with the feed amount. Although most of them can be separated, there will still be some impurities with smaller particles that will be discharged along the outlet of the fan. , the dust removal effect is not good, forming air pollution

It affects and destroys the surrounding environment, and the cyclone dust collector cannot be effectively controlled. The only thing that can be controlled is to control the source of the feed, but it increases a lot of labor intensity for the operator, and the result is not good for dust removal. The efficiency and quality achieved in the process are not ideal
