Pulverizer for biological hydrogen production

The utility model discloses a pulverizer for biological hydrogen production. The pulverizer comprises a case with an inner cavity, wherein a pulverizing device is arranged in the inner cavity, the inner cavity is divided into a pulverizing cavity and a blending cavity by a partition plate, the partition plate is provided with multiple interconnecting holes for interconnecting the pulverizing cavity with the blending cavity, the pulverizing device is arranged in the pulverizing cavity, the upper ends of the pulverizing cavity and the blending cavity are respectively provided with a pulverized substrate inlet and a blended substrate inlet, and the lower end of the pulverizing cavity is provided with a mixed substrate outlet with a valve. According to the pulverizer, because the partition plate is additionally arranged in the case, the inner cavity of the case is divided into a pulverizing cavity and a blending cavity by the partition plate, and the partition plate is provided with multiple interconnecting holes for interconnecting the pulverizing cavity with the blending cavity, a pulverized substrate and a blended substrate can be fully mixed while the substrates are pulverized, so that the approach of pulverizing firstly and then stirring in a traditional technology is replaced, the time of the hydrogen production is greatly shortened; and the pulverized substrate and the blended substrate are mixed relatively fully and completely, and therefore, the fermentation effect is relatively good.
