Problems solved by technology

[0004] When the through-wall mixer is used in a high solid content (8%-12%) sludge fermentation tank, since the stirring impeller of the mixer is inside the fermentation tank, its own weight is large; When the mixer is running at high speed, there are problems such as poor stability, large vibration and large wear of the stirring shaft in contact with sludge; and in some cases, once the power part of the mixer or the stirring shaft fails, especially when the stirring shaft fails, How to get rid of the failure of the mixer without discharging the sludge feed liquid in the fermenter is a difficult problem restricting the technical field

Abstract

The invention discloses a through-wall stirrer, and belongs to equipments for stirring sludge in a sludge fermentation tank. The through-wall stirrer comprises a power part, a stirring part and a support par, wherein the power part and the stirring part are connected; the stirring part is mounted on the support part; a stirring shaft of the stirring part is sleeved within a shaft tube of the support part; the stirring shaft is composed of three sections of transmission shaft and two sleeve-type couplers; and a stirring paddle 13 is mounted at the tail end of an inner side stirring shaft 6. The through-wall stirrer helps to solve the problems of vibration and low transmission efficiency caused by poor straightness and rigidity of the transmission shaft under the condition that the transmission shaft is too long when a present through-wall stirrer is used for stirring the sludge with a high solid content. The through-wall stirrer has the advantages of simple structure, safety, stability and high efficiency in maintenance operation.

Description

technical field [0001] The invention belongs to the technical field of stirring equipment, and more specifically, belongs to a kind of equipment for stirring sludge in a sludge fermentation tank. Background technique [0002] In the last century, domestic and foreign manufacturers generally used submersible mixers and vertical mixers to uniformly mix large sludge fermentation tanks; submersible mixers had problems such as installation, maintenance, waterproofing and anti-corrosion. When using a vertical mixer, the motor is required to provide very high power for the stirring shaft; at the same time, higher requirements are required for the material and strength of the stirring shaft of the vertical mixer. [0003] In order to solve the problems of high-speed stability, easy installation, and maintenance of mechanical mixers, at the beginning of this century, foreign countries took the lead in developing through-wall mixers and applied them in sludge fermentation tanks for un...
