Powdered activated carbon pressure pipeline conveying device

Abstract

The invention discloses a powdered activated carbon pressure pipeline conveying device which comprises a pushing system, a pushing piston, a pushing bracket, a feeding hopper, a compressed exhausting / water pipe and a conveying pipe in sequential connection, wherein the pushing piston is fixedly connected with the tail end of the pushing system and does reciprocating motion in the pushing bracket,the feeding hopper and the compressed exhausting / water pipe under the action of the pushing system to push the material in the conveying pipe and realize material conveying in the pipe. According to the invention, a brand new powder conveying manner is initiated, under the action of powerful external force, the powder is pushed in a closed space, the efficiency is high, dust pollution is avoided,the structure is simple, the failure rate is extremely low, the conveying distance is long, the pipe arrangement flexibility is high, the adaptability is high, and an extrusion dehydration function isfurther realized especially for the semi-dry state powdered activated carbon.

Description

technical field [0001] The invention belongs to the technical field of industrial devices, and in particular relates to a pressure pipeline conveying device for powdered activated carbon. Background technique [0002] As a widely used adsorbent, activated carbon has a considerable annual usage in various industries. The use of activated carbon has strong economic and environmental benefits, and is supported and encouraged by national policies. [0003] In the field of water treatment and sewage purification, activated carbon has two delivery states: one is the dry state before the carbon powder is added to the sewage, and the other is the semi-dry state separated from the water (containing about 50% of water, when placed statically, the surface is In a dry state, dust can float in the exposed air; after being stirred, it will become a muddy state). [0004] The powder conveying devices currently on the market include: belt conveying, screw auger conveying, pneumatic conveyi...

AI Technical Summary

Problems solved by technology

Due to dust pollution, belt conveying cannot be used for powdered activated carbon in dry state; due to viscosity, pneumatic conveying, pipe chain / cable conveying cannot convey powdered activated carbon in semi-dry state; auger conveying can convey both dry powdered activated carbon and semi-dry powdered activated carbon. Dry powder activated carbon, but the conveying of the auger should make use of the self-weight and non-stickiness of the material. Once the powder encounters resistance, even if it is a very small resistance, it is very easy to cause blockage and jamming, and due to the length limit of the screw shaft , a single auger cannot achieve long-distance transportation, so no matter whether the auger is used to transport dry or semi-dry materials, the efficiency is extremely low and the failure rate is extremely high
