Cyclic heating fermentation tank

Abstract

The invention discloses a cyclic heating fermentation tank. The cyclic heating fermentation tank comprises a tank body, a cyclic packing auger, and a cyclic cylinder; the cyclic packing auger is designed to penetrate an internal cavity of the cyclic cylinder so as to form a circulating channel used for material cyclic flow in the interval cavity; the internal wall of the circulating channel is connected with a heating structure used for heating materials flowing in the internal cavity of the cyclic cylinder. The heating structure can be used for heating or thermal insulation of materials in circulation, no heating dead angle is left, heating is more uniform and full, and fermentation effect is excellent.

Description

technical field [0001] The invention relates to the field of organic fertilizer fermentation devices, in particular to a circulation heating fermenter. Background technique [0002] In agricultural production, fertilizers play an important role. From ancient times to modern farming processes, in order to ensure that crops have enough nutrients to grow, people have developed many types of fertilizers, which mainly include two categories, namely organic fertilizers and chemical fertilizers. , chemical fertilizers are gradually being improved and replaced or reduced because of their long-term use will cause deterioration of the soil environment. Organic fertilizers are more environmentally friendly and effective because they are suitable for the normal operation mode of nature. Organic fertilizers are usually made of crop straw and animal manure. Fermentation tanks are extremely important equipment in the production of organic fertilizers. [0003] The current fermentation tan...

The Chinese patent with the authorized notification number CN 206345805 U discloses a fermenter for organic fertilizer production, including a tank body, which is wrapped with a heat medium circulation chamber, and a stirring mechanism driven by a rotating motor 3 is arranged in the tank body. It includes a stirring shaft with two helical blades and several hollow stirring rods. The helical blades can push the organic fertilizer at the upper and lower ends of the tank to the middle of the tank for full stirring. The fermenter can provide the temperature required for the fermentation of farmyard manure conditions, the fermentation is complete, but the fermenter relies on two helical blades to force the organic fertilizer to the middle to make the organic fertilizer circulate. Although the stirring shaft is broken, it is still easy to cause the organic fertilizer to stick to form plates or strips, and Since the heat medium circulation chamber is wrapped around the outside of the tank, it is very easy to form a blind area for organic fertilizer activities at the edge, thereby affecting the fermentation and heating effects. Therefore, the fermentation tank is not heated uniformly.
