Problems solved by technology

[0002] When feeding the closed tank, in order to prevent the gas in the tank from overflowing, gas-blocking feeding is required. At present, pneumatic conveying is mostly used to realize gas-blocking feeding. Pneumatic conveying uses compressed gas as the power source, and the material is transported through the delivery pipe Send to the airtight tank, the conveying speed is high, the cloth is uniform, but the gas consumption is large, and it is prone to blockage

Abstract

The invention discloses a choke feeding screw conveyor which comprises a cylindrical housing, wherein a feed port and a discharge port are formed on the cylindrical housing, an electric motor is arranged at the end of the feed port of the cylindrical housing, a shaft helical blade and a shaftless helical blade are arranged in the cylindrical housing, the electric motor is in power connection withthe shaft helical blade, the shaft helical blade is connected with the shaftless helical blade, and a sealing water return port is arranged at the back part of the discharge port of the cylindrical housing; due to the adoption of the shaft helical blade, the choke feeding screw conveyor can ensure that materials and water can be pushed forwards, further prevent backflow of the water, and play a water-blocking role; due to the adoption of the shaftless helical blade, the choke feeding screw conveyor can ensure that a sealing water body can not completely enter into a closed tank body; and an inner cavity of the housing at the starting end of the shaftless helical blade is water-sealed, thereby realizing sealing between a feeding machine and the closed tank body, preventing overflow of gas in the tank, having good choke effect and higher conveying speed and further having compact structure.

Description

technical field [0001] The invention relates to a gas barrier feeding device. Background technique [0002] When feeding the closed tank, in order to prevent the gas in the tank from overflowing, gas-blocking feeding is required. At present, pneumatic conveying is mostly used to realize gas-blocking feeding. Pneumatic conveying uses compressed gas as the power source, and the material is transported through the delivery pipe It is sent to a sealed and airtight tank with high conveying speed and uniform cloth distribution, but the gas consumption is large and blockage is prone to occur. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gas-blocking feeding screw conveyor with good gas-blocking effect, high conveying speed and compact structure. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is: the air-blocking feeding screw conveyor includes a c...
