Abstract
The utility model discloses a device for generating biogas via a ball-milling treatment on straw, and in particular relates to a device for performing a ball-milling treatment on straw and then fermenting. According to the device, a clapboard is arranged in the device, and a pre-treatment device is arranged on one side of the clapboard; a charge port is additionally formed in the upper part of the pre-treatment device, and a ball-milling treatment device is additionally arranged on the lower part of the charge port; a ceramic grinding device is additionally arranged in the ball-milling treatment device; a discharge port is additionally formed in the lower part of the pre-treatment device, a fermentation device is arranged at the other side of the pre-treatment device, and a stirring device is additionally arranged in the pre-treatment device; the rotary shaft of the stirring device is connected with the upper end of the device, and a stirring paddle is installed at the lower end of the device; an isolation plate is installed at the middle part of a reactor, and the rotary shaft of the stirring device penetrates through the isolation plate. During fermentation, straw enters the pre-treatment device after being subjected to the ball-milling treatment of the ball-milling treatment device, and a pre-treatment is performed in the pre-treatment device; the stirring device can be used for stirring fermentation materials, and the fermentation materials are isolated on the lower part by the isolation plate, so as to prevent the case of incomplete fermentation of straw, so that the fermentation rate of straw is increased.
Description
Technical field
The utility model relates to a kind of stalk ball-milling processing and produces the biogas device, especially stalk is carried out the device that ferments again after the ball-milling processing.
Background technology
Along with the development of agriculture production, China is since the eighties in 20th century, and grain yield significantly improves, and stalk quantity also increases, because burning straw, so that the concentration of flue dust, particulate matter and other pollutents sharply increases in the air, Air quality descends rapidly.Fermentation reactor is a kind of device of fermentation gas commonly used, stalk can be carried out producing methane through anaerobic fermentation, but the Structure Decreasing on stalk surface the fermentation efficiency of stalk, limited the fermentation of stalk.
Summary of the invention
In order to solve the problem of stalk surface tissue restriction stalk fermentation rate, the utility model provides a kind of stalk ball-milling processing to produce the biogas device, and this device carries out stalk to ferment after the ball-milling processing again, has improved simply and easily the fermentation rate of stalk.
The technical scheme that its technical problem that solves the utility model adopts is: device inside has dividing plate, dividing plate one side is pretreatment unit, the top of pretreatment unit installs opening for feed additional, the opening for feed bottom installs the ball-milling processing device additional, ball mill device inside installs the ceramic grinding device additional, install discharge gate additional in the pretreatment unit bottom, opposite side is fermentation unit, and its inside installs whipping appts additional, and the rotating shaft of whipping appts is connected with the device upper end, stirring rake is installed in the lower end of rotating shaft, division board is installed at the reactor middle part, has small hole on the division board, and division board is passed in the rotating shaft of whipping appts, the shell upper end has gas recovery pipe, and nutritive medium adds pipe.When fermenting, stalk enters pretreatment unit after ball-milling processing, and carries out pre-treatment interior, whipping appts can stir fermented product, fermented product is isolated plate and is isolated in the bottom, and this just prevents the incomplete situation of stalk fermentation, has improved the stalk fermentation rate.
The beneficial effects of the utility model are that the stalk ball-milling processing produces the biogas device, and stalk is carried out fermenting after the pre-treatment again, has improved the stalk fermentation rate.
