Technical Field

[0001] The utility model relates to the technical field of material discharge devices, in particular to a material discharge device which is convenient for quickly discharging materials from a fermentation tank. Background Art

[0002] Fermentation tanks are commonly used equipment for producing fermented products. After the materials inside the fermentation tanks are fully stirred and fermented, the materials need to be discharged from the fermentation tanks. However, the discharge devices used by fermentation tanks with different structures on the market are also different.

[0003] For example, a Chinese patent application with publication number CN116082073A discloses a feeding structure for an organic fertilizer fermentation tank, the feeding structure for an organic fertilizer fermentation tank comprises a fermentation tank body, a stirring assembly is arranged in the fermentation tank body, the bottom end of the stirring assembly is rotatably connected to the upper surface of the bottom plate, the bottom plate is rotatably connected to the fermentation tank body, a feeding assembly is arranged on the fermentation tank body, the feeding assembly is arranged above the bottom plate, and a plurality of groups of partitions are arranged on the bottom plate, and the partitions are installed on the lifting assembly; the beneficial effect is: the bottom plate at the bottom end of the stirring assembly is slidably connected to the fermentation tank body, when the stirring assembly is completed and the organic fertilizer is discharged, the bottom plate can be rotated to facilitate the discharge of the organic fertilizer, and the organic fertilizer far away from the discharge port can be rotated to the discharge port to avoid that some organic fertilizer is difficult to discharge and causes waste, and a liftable partition is arranged on the bottom plate, and the partition is used to accelerate the rotation of the organic fertilizer to the discharge port, so as to speed up the feeding speed.

[0004] Fermentation tanks are mainly divided into vertical tanks and horizontal fermentation tanks. The discharge device of the vertical fermentation tank is mostly installed at the bottom, and will not interfere with the stirring mechanism of the vertical fermentation tank, and can also assist the vertical fermentation tank to discharge materials quickly.

The discharge structure provided by the above patent is for vertical fermentation tanks, and cannot assist the horizontal fermentation tank to quickly discharge the material inside it, resulting in low discharge efficiency and troublesome discharge of the horizontal fermentation tank.
