Material bag air-washing system

Abstract

The invention discloses a material bag air-washing system, which comprises a material bag, a mixing barrel, an air supply device and a dust collecting device, wherein the dust collecting device is connected with an air inducing device; an opening at the upper end of the material bag is communicated with the air supply device, and a discharge hole at the lower end of the material bag is communicated with the mixing barrel; the mixing barrel is communicated with the dust collecting device; after the material bag is unloaded by adopting a feeding device, in order that the residual material in the material bag is separated from the material bag, the discharge hole at the lower end of the material bag is communicated with the mixing barrel, the air inducing device and the air supply device are turned on, the material bag fully swells through airflow produced by the air inducing device and the air supply device, the residual material in the material bag is blown off by the airflow, the material is fully separated under the coordination of beating on the outer part of the material bag, the material separated from the material bag is brought into the mixing barrel by the airflow, a part of the material is mixed with water in the mixing barrel for adding, and the other part of the material is brought to the dust collecting device by the airflow for adding or reutilization.

Description

technical field [0001] The invention relates to an auxiliary facility of a powder material wet feeding device, in particular to a material bag air washing system. Background technique [0002] The pollution of drinking water sources in my country is becoming more and more serious, and there are many types of organic substances in water sources. In the process of water treatment, activated carbon is usually added to adsorb and remove organic substances and other impurities in raw water. Due to the large specific surface area of ​​powdered activated carbon, it has strong adsorption, which can effectively remove the color, turbidity and peculiar smell of raw water, and effectively reduce the pollutant content in raw water. [0003] The dosing method of powdered activated carbon usually adopts the wet dosing method, that is, after mixing the powdered activated carbon with water, the mixture of powdered activated carbon and water is injected into the raw water through a metering ...

AI Technical Summary

Problems solved by technology

The existing manual, automatic or self-integrated powdered activated carbon dosing devices generally have hoppers, occupy a large area, and are only suitable for installation outdoors. Existing powdered activated carbons generally use special packaging bags The powdered activated carbon in the bag is generally put into the feeding pump truck and transported to the water plant during the specific operation, and then the powdered activated carbon in the feeding pump truck is pumped into the silo for dosing, so A bit cumbersome to operate

Moreover, the powdered activated carbon dosing devices in the prior art are relatively large, so the equipment investment cost is relatively high, and generally have a supporting control system, which also involves many electronic control equipment, resulting in high maintenance and maintenance costs for the equipment.

[0004] However, the addition of powdered activated carbon is generally used when the water quality is poor. There are relatively few times when water plants need to add a large amount of powdered activated carbon within a year. Smaller, powdered activated carbon does not need to be added for most of the year, so the powdered activated carbon dosing device is idle most of the time, and because the powdered activated carbon dosing device of the prior art is relatively large and has a one-time investment cost and maintenance costs are higher, thus causing a certain degree of waste
