Discharging mechanism of straw discharge cleaning on upper part of straw methane anaerobic tank

Abstract

The invention discloses a discharging mechanism of straw discharge cleaning on the upper part of a straw methane anaerobic tank and the discharging mechanism is characterized by comprising a cleaning device and a spraying mechanism, wherein the cleaning device is installed on the cabin top of an anaerobic tank in a suspension mode; the spraying mechanism is arranged on the cabin top of the anaerobic tank; the cleaning device comprises a rotary shaft and a blade, wherein the rotary shaft penetrates through the cabin top of the anaerobic tank, and extends downward vertically to the part above aliquid level; the blade is installed on the rotary shaft in a fixed mode, and the rotary surface of the blade and the water level form an inclined angle of 60 degrees; a power driven mechanism which is used for driving the rotary shaft to perform a rotary motion and is composed of a motor and a speed reducer is installed on the cabin top of the anaerobic tank through a supporting frame; and the extending section connected by the rotary shaft of the cabin top of the anaerobic tank and the speed reducer is provided with a water seal.

Description

technical field [0001] The invention relates to a straw cleaning and discharging mechanism for the upper part of the straw biogas anaerobic tank. The cleaning device is particularly suitable for cleaning and discharging the upper part of the straw biogas anaerobic tank. Background technique [0002] At present, a large number of plant straws are produced in vast rural areas every year, but they are burned in many areas, which is not only a waste of resources, but also seriously pollutes the environment. The emergence of straw biogas has solved such a problem. [0003] However, the use of straw fermentation can cause a lot of scum on the upper part of the reaction tank. At present, there is no good solution to this problem. The usual method is to design an angle of 60 degrees on the top of the anaerobic tank, relying on the gravity of the biogas residue to make it fall into the discharge port; or add an oblique stirring device to one side of the bin to circulate the upper sc...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a straw cleaning and discharging mechanism for the upper part of the straw biogas anaerobic reaction tank in view of the problems that the upper part of the large-scale straw biogas anaerobic reaction tank cannot be cleaned and the removal is not thorough.
