Embodiment Construction

[0019] The present invention will be further described below in conjunction with the drawings.

[0020] See figure 1 , A biogas fermentation tank agitator, which includes a transmission device installed on the top of the fermentation tank 5 and a stirring device installed in the fermentation tank 5. The transmission device is composed of a motor 1, a reducer 2 and a rotary gear box 3. The stirring device is composed of a stirring shaft 8, a stirring paddle 9 and a shell-breaking structure, and the stirring device and the transmission device are fixedly connected by a coupling 4. The shell-breaking frame is composed of a support rod 6 and a serpentine grid 7. The stirring paddle 9 has several layers.

[0021] See figure 2 The slewing gear box is composed of a box body 10 and a slewing support 11 and a gear shaft 12 installed in the box body 10. The ring gear of the slewing support 11 meshes with the gear shaft 12, and the shaft head of the gear shaft 12 and the reducer The outpu...

Abstract

The invention relates to a stirrer of a biogas fermentation tank. The stirrer comprises a transmission device and a stirring device, wherein the transmission device is mounted at the top of the fermentation tank; the stirring device is mounted in the fermentation tank; the transmission device consists of a motor speed reducer and a rotary gear box; the stirring device consists of a stirring shaft,stirring paddles and a shell breaking frame; the stirring device and the transmission device are fixedly connected through a coupling; the rotary gear box consists of a box body, a rotary bearing anda gear shaft which are mounted in the box body; a gear ring of the rotary bearing meshes with the gear shaft; a shaft head of the gear shaft is connected with an output shaft of the speed reducer; and the shell breaking frame consists of a supporting rod and snakelike grid bars. The device has the advantages of simple structure, stable operation and long service life, the problems existing in theexisting stirrers of biogas fermentation tanks are solved, the long-term stable production of the biogas fermentation tank is guaranteed, and the gas production rate of the fermentation tank is improved.

Description

Technical field [0001] The invention relates to the field of biogas fermentation, in particular to a stirrer of a biogas fermentation tank. Background technique [0002] Biogas is a kind of combustible gas produced by fermentation of organic matter. It is the same as wind energy and solar energy. It is a renewable clean energy. With the increasing maturity of biological fermentation technology, more and more companies use straw, livestock manure and industrial waste to prepare biogas, and the industrialized production of biogas is emerging nationwide. [0003] Since the industrialized production of biogas is carried out in the fermentation tank, the more fully mixed the various biological raw materials during the fermentation process, the greater the gas production, so it must be continuously stirred with a stirrer. [0004] There are two types of fermenter agitators currently in use, side-entry and top-entry. The side-entry agitator is installed on the wall of the bottom of the fer...
