Embodiment Construction

[0087] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0088] like figure 1 , 5As shown, the biogas fermentation system includes a fermentation tank body 10, a gas storage plate 20, and a water pressure room 40. The water pressure room 40 is connected to the upper part of the fermentation tank body 10 through water pipes, and the gas storage plate 20 is fixed in the fermentation tank body 10. The area between the left end of the gas storage plate 20 and the fermentation tank body 10 is the feed inlet 12, the area b...

Abstract

The invention discloses a pneumatic mixing and stirring device which comprises a methane fermenting system and stirring sleeves. The methane fermenting system comprises a methane storing plate, a plurality of blocking plates are arranged in the methane storing plate, the methane storing plate is divided into a plurality of fermenting areas by the blocking plates, the stirring sleeves are fixed to the upper ends of the blocking plates, the two ends of the stirring sleeves are symmetrical with each other, pneumatic pistons are in sliding connection in the stirring sleeves in a sleeved mode, the two ends of the pneumatic pistons are respectively connected with outer sleeves through piston connecting rods, the outer walls of the two ends of the stirring sleeves are respectively connected with springs in a sleeved mode, step cavities matched with the outer lateral walls of the stirring sleeves are arranged on the outer sleeves, communicating holes communicated with the fermenting areas and the step cavities are further formed in the outer sleeves, and the outer sleeves are fixedly connected with stirring nets.

Description

technical field [0001] The invention relates to a pneumatic mixing and 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 sundries inside, and then poke through the rod body. [0003] The biogas slurry produced by the fermentation of animal manure is tasteless after fermentation and the fertilizer effect after fermentation is ...
