Automatic crust breakage biogas fermentation tank

Abstract

The invention discloses an automatic crust breakage biogas fermentation tank. The tank body of the automatic crust breakage biogas fermentation tank is provided with a hydraulic pressure chamber, a gas storage chamber and a fermentation chamber in sequence from top to bottom, wherein the hydraulic pressure chamber is communicated with the fermentation chamber through a communicating pipe; the gas storage chamber is connected with a gas delivery pipe which leads to the exterior of the tank body; the fermentation chamber is connected with a feed pipe which is inserted from the exterior of the tank body; a cross frame and a plurality of crust breakage cones are arranged in the gas storage chamber; the bottom end of each crust breakage cone is a tip and faces towards the fermentation chamber; the top end of each crust breakage cone is fixedly connected with a bottom plate of the hydraulic pressure chamber; and the cross frame is fixedly connected with the tank body. By arranging an automatic crust breakage device in the fermentation tank, not only can a scum crust layer be crushed, but also the crust layer can be softened and soaked, so that a part of scums are settled and digested again, the raw material conversion rate is improved, the scum formation is reduced, and the scum is discharged easily.

Description

Technical field [0001] The invention relates to a biogas fermentation device, in particular to a movable automatic shell-breaking biogas fermentation tank. Background technique [0002] Movable plastic biogas fermentation tank is composed of hydraulic room, fermentation room, gas storage room, etc. Because of its advantages such as easy installation and convenient management, it is welcomed by users. However, because there is no stirring device in the fermentation tank, scum crusts easily appear above the liquid level, resulting in low raw material utilization and reduced gas production. The main reason is that in the anaerobic fermentation process, some of the organic matter such as straws in the raw materials forms scum under the action of buoyancy. With the passage of fermentation time, scum continued to form and float, causing the scum on the liquid surface to thicken day by day. Without the disturbance of external force, the scum on the liquid surface will form a crust la...

Problems solved by technology

The latter method requires higher water pressure, which is not available in many rural areas, and the area of ​​scum crushed is limited

However, other simple and practical automatic shell breaking methods suitable for plastic biogas fermentation tanks are rarely applied and publicly reported.
