Stirring apparatus for reaction kettle

Abstract

The invention discloses a stirring apparatus for a reaction kettle, comprising a rotating shaft, an external spiral ring surrounding the rotating shaft, a plurality of supporting plates mounted on the rotating shaft in sequence radially and asymmetrically according to the phase difference of 90 degrees and a plurality of paddles, wherein the first end of the supporting plat is further from the central axis of the rotating shaft compared with the second end and is connected with the external spiral ring; and the paddles form an intermittent spiral ring along the axis of the rotating shaft and are mounted at the second ends of the supporting plates, respectively. Spiral direction of the intermittent spiral ring is opposite to that of the external spiral ring. The reaction kettle has reasonable designed structure, diversified material moving forms during stirring, adequate stirring and improved efficiency and the materials are not easy to pile up.

Description

technical field [0001] The invention relates to a waste treatment device, in particular to a reactor stirring device. Background technique [0002] In the prior art, on May 21, 2008, the Chinese Invention Patent Bulletin disclosed an invention patent with the publication number CN101184560A and the name "organic waste treatment device and liquid separation and recovery method", which has a closed container, A rotating shaft and a stirring blade are installed in the airtight container. The rotating shaft is arranged horizontally in the airtight container and is rotatably supported by a shaft. The agitating blade is installed on the rotating shaft and has a part that widens in the circumferential direction of the rotating shaft. , the length from the rotating shaft of the stirring blade to the front end of the blade is formed as follows: it corresponds to the horizontal barrel shape of the airtight container, and is longer at the central position in the length direction of the...

AI Technical Summary

Problems solved by technology

[0003] The disadvantage of the above-mentioned treatment device is that the waste is packed into the airtight container and piled up at the bottom of the airtight container due to the effect of gravity. Under the propulsion of the propeller blade and gravity, the trajectory of the waste is almost a straight line, which cannot Turning, squeezing, and stirring are formed. Therefore, the contact between the waste and the steam under high temperature and pressure is insufficient, and the expected hydrolysis, catalysis, extraction, and refinement of various physical and chemical reactions cannot be carried out effectively, so the reaction time and efficiency are prolonged. Low, the overall operation is not ideal, and the expected effect cannot be achieved
