As shown in fig. 1 to 2, a mirror image pressure differential type biogas anaerobic fermentation tank includes: the anaerobic fermentation tank comprises a first anaerobic fermentation tank 1, a second anaerobic fermentation tank 2, a connecting pipe fitting 3, a valve 4 and a stirring unit 5;
the first anaerobic fermentation tank 1 and the second anaerobic fermentation tank 2 are the same in volume and shape, and the height of the first anaerobic fermentation tank 1 is higher than one half of the height of the second anaerobic fermentation tank 2; no. 1 anaerobic fermentation pond and No. 2 anaerobic fermentation ponds are the cuboid type pond that two cement built, highly are 6m, and length is 32m, and the top of No. 2 anaerobic fermentation ponds is located the centre of No. 1 anaerobic fermentation ponds, and No. 1 anaerobic fermentation ponds are higher than No. 2 height 3m promptly. The biogas residue in the first anaerobic fermentation tank 1 is reserved, and the biogas slurry in the upper half part is discharged to the second anaerobic fermentation tank 2.
Obviously, most anaerobic fermentation ponds are arranged underground, and in order to reduce the land area, the first anaerobic fermentation pond 1 and the second anaerobic fermentation pond 2 are arranged in a butting mode.
Further, one end of the connecting pipe fitting 3 is connected above the side wall of the first anaerobic fermentation tank 1, and the other end of the connecting pipe fitting is connected with the top of the second anaerobic fermentation tank 2; the connecting pipe fitting 3 is a steel water pipe, and aims to discharge biogas slurry to the second anaerobic fermentation tank 2.
Further, a valve 4 is arranged on the connecting pipe fitting 3; the valves 4 are ball valves and are three in number, with the aim of ensuring tightness.
Further, a stirring unit 5 is arranged in each of the first anaerobic fermentation tank 1 and the second anaerobic fermentation tank 2; every stirring unit 5 includes eight mixers, and equidistant evenly distributed becomes two, four mixers of every row promptly to the direction of rotation of two mixers is opposite, and one is clockwise rotation, and another is anticlockwise rotation, and its aim at, when two mixers opposite direction of rotation, two regional natural pond liquid in middle part of mixer can not produce the vortex, but move towards one direction.
Further, a feeding hole 6 is formed in one side above the first anaerobic fermentation tank 1; a discharge hole is formed in one side of the bottom of the second anaerobic fermentation tank 2, an output pipeline is arranged on the discharge hole, and an output valve is arranged on the output pipeline.

And the third fermentation tank, the first fermentation tank and the second fermentation tank are independently fermented, so that the problem that the direct current decomposition of new materials generated by feeding is not thorough is solved. And the fourth fermentation tank and the second fermentation tank continuously ferment the old materials for four days, so that biogas residues obtained after the raw materials are completely converted into biogas can be directly used for producing organic fertilizers without the secondary aerobic fermentation problem.
The working principle of the device is as follows: two independent anaerobic fermentation tanks with certain height difference are connected through pipe fittings, and biogas slurry is pushed to the other anaerobic fermentation tank through the pipe fittings by the reverse rotation of the two rows of stirrers, so that biogas residues in the first anaerobic fermentation tank continue to precipitate, strains grow better, and the anaerobic conditions of the fermentation tanks are ensured.
