Novel horizontal fermentation tank

Abstract

The invention discloses a novel horizontal fermentation tank, which belongs to the field of stirring, and comprises a horizontal tank cylinder body, a main transmission shaft is rotatably connected in the horizontal tank cylinder body, a stirring motor is mounted and connected at the left end of the main transmission shaft, and a stirring shaft is fixedly connected at the right end of the main transmission shaft. A plurality of groups of stirring blades is arranged on the stirring shaft, a bottom plate is arranged at the lower end of the horizontal tank barrel, one side of the bottom plate is rotatably connected to the bracket, a lifting device is mounted on the other side of the bottom plate, and compared with the prior art, the invention has the advantages of damping, enhancing the stirring strength, scraping dirt on the inner wall and the like.

Description

technical field [0001] The invention belongs to the technical field of stirring, and in particular relates to a novel horizontal fermenter. Background technique [0002] At present, anaerobic fermentation tanks are divided into vertical and horizontal fermentation tanks. The vertical type uses 2-3 layers of stirring paddles to stir, and the axial stirring is carried out. The upper and lower materials cannot be stirred and mixed, and the stirring effect is poor. The horizontal type adopts the fermentation mode of spraying on the upper part and composting at the bottom, without a stirring device, which leads to uneven mixing of materials and difficulty in feeding and discharging materials. This device, through the design of the stirring shaft and the stirring seal of the horizontal tank, overcomes the axial pressure seal of the stirring paddle and the horizontal center drag force, strengthens the stirring, and ensures the heat and mass transfer of the material; the design of ...

AI Technical Summary

Problems solved by technology

The vertical type uses 2-3 layers of stirring paddles to stir, and the axial stirring is carried out. The upper and lower materials cannot be stirred and mixed, and the stirring effect is poor.

The horizontal type adopts the fermentation mode of upper spraying and bottom composting, without a stirring device, resulting in uneven mixing of materials and difficulty in feeding and discharging materials.

This device, through the design of the stirring shaft and the stirring seal of the horizontal tank, overcomes the axial pressure seal of the stirring paddle and the horizontal center drag force, strengthens the stirring, and ensures the heat and mass transfer of the material; the design of the screw pump feed and the gas-liquid separator ensures Automatic feeding and discharging; design of lifting device to ensure rapid gas outlet and enhance fermentation efficiency; traditional mixing device, the position between the mixing tank and the paddle is relatively fixed, resulting in a fixed mixing area. For some viscous materials, it is easy to cause problems such as uneven mixing.
