Embodiment Construction

[0073] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0074] like Figure 1-5 As shown, the biogas fermentation system includes a fermentation tank body 10, a gas storage plate 20, and a partition plate 30. The partition plate 30 is arranged in the fermentation tank body 10 and separates the fermentation tank body 10 into S-shaped or W-shaped fermentation chambers. In the fermentation tank body 10, a gas storage plate 20 matching the shape of the fermentation chamber is fixed, and the two ends of...

Abstract

The invention discloses a self-circulation stirring device which comprises a stirring sleeve, wherein the stirring sleeve is fixed above a gas storage plate of a biogas fermentation system and is communicated with two fermentation areas which are arranged in the gas storage plate at an interval, a pneumatic piston which separates the two fermentation areas is slidably connected in the stirring sleeve in a sleeving mode, two ends of the pneumatic piston are connected with an outer sleeve through piston rods respectively, springs are connected onto outside walls at two ends of the stirring sleeve in a sleeving mode, step cavities matched with the outside wall of the stirring sleeve are arranged on the outer sleeve, communication holes which communicate the step cavities are formed in the outer sleeve, and the outer sleeve is fixedly connected with a stirring net.

Description

technical field [0001] The invention relates to a self-circulation stirring device. Background technique [0002] The latest national standard for biogas digesters released in 2002 includes 5 types of ponds, namely hydraulic cylindrical biogas digesters, separated floating cover biogas digesters, meandering cloth biogas digesters, prefabricated block (cylindrical) biogas digesters and ellipsoidal biogas digesters. Biogas digester: The cylindrical biogas digester is a pipe-type biogas digester. Fermentation raw materials enter the fermentation pipeline to ferment to produce biogas, and accumulate in the fermentation pipeline, which is easy to cause blockage of the fermentation pipeline; if the blockage is deep, it is usually used to clear the fermentation pipeline All the sundries inside, and then poke the cylinder through the rod body. [0003] The biogas slurry produced by the fermentation of animal manure is tasteless after fermentation and the fertilizer effect after fer...
