Description

Technical Field

[0001] The utility model relates to the technical field of feces fermentation stirring reaction, in particular to a stirring machine suitable for disassembling an aeration head. Background Art

[0002] The twin-shaft mixer is an important equipment in the technical process of feces fermentation. The twin-shaft mixer is used to achieve the mixing of materials and auxiliary materials. In the mixer, the materials must not only be mixed, but also have sufficient reaction time. At present, the feed port of the existing twin-shaft mixer is set at one end of the twin-shaft mixer, and the discharge port is set at the end away from the feed port. Therefore, the material enters from the feed port and exits from the discharge port in only one stroke to achieve uniform mixing of the material, resulting in a shorter residence time of the material in the mixer, and thus unable to provide sufficient reaction time. Moreover, since the discharge port is located at the end of the twin-shaft mixer, problems such as material accumulation, long discharge time and unclean discharge are prone to occur. In addition, since the auxiliary materials include both powdered auxiliary materials and gaseous auxiliary materials. The mixing of gaseous auxiliary materials requires the help of an aeration head. In order to ensure the uniformity of mixing of gaseous auxiliary materials, at present, the aeration head of the existing twin-shaft mixer is evenly installed on the inner wall of the mixing tank along the length direction of the twin-shaft mixer. When the air outlet of the aeration head of the gaseous auxiliary material is blocked by the material, it is difficult to replace and clean the blocked aeration head, which affects the mixing efficiency of the material and the auxiliary material.

[0003] In summary, the existing double-shaft mixers used in feces fermentation processes have problems such as short residence time of materials in the mixer, insufficient reaction time, easy accumulation of materials, long discharge time, unclean discharge, and difficult replacement of the aeration head for gaseous auxiliary materials.

[0016] Compared with the prior art, the utility model has the following effects:

[0017] 1. The utility model is suitable for the mixer with detachable aeration head. The materials in the mixer must not only be stirred, but also have sufficient reaction time.

[0019] 3. The mixer suitable for disassembling the aeration head of the utility model has the aeration head 7 installed on the bottom bin door 6, and the aeration head 7 is threadedly connected to the bottom bin door 6. In this way, after the unloading is completed, the electric hydraulic push rod 4 is used to drive the bottom bin door 6 to open, so that the aeration head 7 that is blocked by dirt can be easily disassembled, and the new aeration head 7 can be replaced conveniently.
