Description

Technical Field

[0001] This utility model relates to the technical field of livestock and poultry treatment equipment, and in particular to a fermentation equipment for harmless treatment of livestock and poultry. Background Technology

[0002] Nowadays, farms often use high-temperature wet processing equipment to harmlessly treat diseased and dead livestock and poultry. After the diseased and dead livestock and poultry are treated by the high-temperature wet processing equipment, a certain amount of wastewater and residue will remain. The remaining wastewater will be discharged into the sewage treatment plant or septic tank, and the remaining residue is usually directly fermented as organic fertilizer. However, the direct fermentation of a large amount of residue has the disadvantages of insufficient fermentation and long fermentation cycle.

[0003] Therefore, a fermentation equipment for the harmless treatment of livestock and poultry is needed to solve the above problems. Utility Model Content

[0004] This utility model proposes a livestock and poultry harmless treatment fermentation equipment, which is equipped with a multi-chamber structure to realize secondary fermentation of residues and ensure that the residues are fully fermented into organic fertilizers.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A livestock and poultry harmless treatment fermentation equipment includes a tank body, which comprises a pre-fermentation tank, a temporary storage tank, a mixing tank, and a secondary fermentation tank, all integrated together. The pre-fermentation tank, temporary storage tank, mixing tank, and secondary fermentation tank are connected in sequence. A spiral feeding assembly is provided inside the temporary storage tank. The mixing tank is connected to a first material bin and a second material bin. A stirring assembly is provided inside the mixing tank. A residue inlet is provided on the pre-fermentation tank. A fermentation product outlet is provided at the bottom of the secondary fermentation tank.

[0007] As a preferred technical solution, the bottoms of the tank, the pre-fermentation tank, the mixing tank, the first material silo, and the second material silo are all conical.

[0008] As a preferred technical solution, the bottom of the mixing tank is provided with a discharge port, and the stirring assembly includes a vertically arranged stirring shaft with its lower end extending into the discharge port. A first bolt blade adapted to the discharge port is fixedly installed on the stirring shaft, and a stirring plate and stirring rod adapted to the bottom of the mixing tank are fixedly installed on the stirring shaft.

[0009] As a preferred technical solution, a feeding port is provided between the temporary storage tank and the mixing tank. The spiral feeding assembly includes a rotating shaft, which is rotatably installed at the feeding port via a bracket. The rotating shaft extends horizontally into the interior of the temporary storage tank and is fixedly fitted with a second spiral blade.

[0010] As a preferred technical solution, at least one pair of vent pipes are fixedly installed on the side wall of the secondary fermentation tank. One end of each vent pipe extends into the secondary fermentation tank and is equipped with an arch-breaking gas disc. Each arch-breaking gas disc is conical and its outer edge is attached to the inner wall of the secondary fermentation tank. Each vent pipe is provided with an air passage for connecting the inner side of the arch-breaking gas disc and the gas source.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0012] Since the livestock and poultry harmless treatment fermentation equipment includes a pre-fermentation tank, a temporary storage tank, a mixing tank, and a secondary fermentation tank, during use, the pre-crushed residue is fed into the pre-fermentation tank in batches for the first fermentation. The fermented residue is then transported to the temporary storage tank and then to the mixing tank through a screw conveyor assembly. In the mixing tank, it is mixed evenly with rice bran powder and inoculum. After being evenly mixed, it is transported to the second fermentation tank for the second fermentation. After the second fermentation is completed, powdered organic fertilizer is obtained.

[0013] In this invention, the tank adopts a multi-chamber structure. The residue sequentially passes through a pre-fermentation tank, a temporary storage tank, a mixing tank, and a secondary fermentation tank, where it undergoes the first fermentation, temporary storage, material mixing, and second fermentation, respectively. This achieves secondary fermentation of the residue, ensuring that the residue is fully fermented into organic fertilizer and solving the problem of insufficient fermentation caused by direct fermentation of large amounts of residue.

[0014] When the secondary fermentation tank is fermenting the current batch of residue for the second time, the pre-fermentation tank can simultaneously ferment the next batch of residue for the first time. After the residue in the secondary fermentation tank has completed fermentation and been discharged, the next batch of residue is stirred and then enters the secondary fermentation tank for secondary fermentation. In other words, this equipment can process two batches of residue at the same time, thereby shortening the overall fermentation time of the residue and solving the problem of long fermentation cycle caused by direct fermentation of a large amount of residue.

[0015] Because the mixing tank is equipped with a stirring assembly, when the stirring assembly is in the stirring state, the first bolt blades convey the material from the bottom of the mixing tank upwards. After being stirred by the stirring plate and stirring rod, the material is mixed evenly, which helps to accelerate the secondary fermentation of the residue. When the stirring assembly is in the discharge state, the stirring shaft rotates in the reverse direction, and the first bolt blades convey the mixed material into the secondary fermentation tank. The stirring plate and stirring rod disperse the material at the discharge port to avoid blocking the discharge port and allow the material to enter the secondary fermentation tank smoothly.

[0016] Because the secondary fermentation tank is equipped with an arch-breaking gas disc, the arch-breaking gas disc does not work during the fermentation process. The outer edge of the arch-breaking gas disc is in contact with the secondary fermentation tank. During the discharge process, the gas source enters between the arch-breaking gas disc and the secondary fermentation tank through the air pipe. The gas pushes up the outer edge of the arch-breaking gas disc and sprays it outwards along the inner wall of the secondary fermentation tank, forming a blowing effect on the material. At the same time, the gas pushes the edge of the arch-breaking gas disc to vibrate. Through the vibration and blowing effect, the powdered organic fertilizer is assisted to move towards the fermentation material outlet, so that the organic fertilizer can be discharged smoothly.
