Technical Field

[0001] The utility model relates to the technical field of manure water treatment, in particular to a wet fermentation device for manure water treatment. Background Art

[0002] Manure water refers to the liquid formed after a certain period of fermentation and decomposition of human or animal excrement. This liquid usually contains a large number of bacteria, viruses, parasites and other microorganisms, as well as various organic and inorganic substances. In the agricultural field, properly treated manure water is sometimes used as fertilizer to provide nutrients for crops. However, direct discharge of untreated manure water into the environment will cause serious pollution and harm to the soil, water sources and ecosystems. In order to promote the decomposition of organic matter, kill harmful bacteria, retain nutrients, improve soil structure and reduce environmental pollution, manure water needs to be wet fermented.

[0003] In the prior art, when the manure water is fermented, it needs to be constantly turned over to avoid insufficient fermentation. Generally, workers pour the manure water into a fermentation tank and then start the stirring component in the equipment to continuously turn the manure water over. However, the traditional stirring device can often only stir the fertilizer from one direction, and the stirring direction is single, which can easily cause uneven stirring and lead to insufficient fermentation. Therefore, a wet fermentation device for manure water treatment is proposed to solve the above problem. Utility Model Content

[0031] Specifically, the fermentation tank 1 is the core component of the whole device, which is used to contain the manure water to be fermented. The rotating column 2 serves as the supporting structure of the fermentation tank 1. The rotating column 2 ensures that the fermentation tank 1 can be placed stably and can be turned to dump out the material when necessary. The supporting column 3 provides a stable support for the whole device, ensuring the stability of the fermentation tank 1 and various power components during operation. The bottom plate 4 is the bottom foundation of the device, carrying all the components, ensuring the stability of the whole structure, and preventing the device from shifting. The motor 6 serves as the driving source, and the motor 6 provides power to drive the rotating shaft 7 and related stirring components to perform stirring. The rotating shaft 7 rotates to achieve mixing and fermentation of manure water. The rotating shaft 7 rotates under the drive of the motor 6. It is the power transmission component of the stirring frame 8 and is fixedly connected with the lower teeth 9 to participate in the two-way stirring mechanism. The stirring frame 8 is fixed on the rotating shaft 7 and rotates with the rotation of the rotating shaft 7 to stir the manure water in the fermentation tank 1 to promote the uniform fermentation process. The lower teeth 9 are fixedly connected with the rotating shaft 7. When the rotating shaft 7 rotates, the lower teeth 9 also rotate accordingly, which meshes with the gear 15 to transmit power and drive the rotation of the gear 15. The rotating shaft 10 rotates under the drive of the gear 15 and the upper teeth 12. It is the support and power transmission component of the stirring frame 11, realizing reverse stirring with the stirring frame 11. The stirring frame 11 fixed on the rotating shaft 10 rotates with the rotation of the rotating shaft 10, and realizes two-way stirring together with the stirring frame 18 to improve the fermentation efficiency of the manure water. The upper teeth 12 are connected to the rotating shaft 10 and rotate under the drive of the gear 15. It, the lower teeth 9 and the gear 15 together constitute a power transmission system to realize the two-way stirring function. The protective shell 13 covers the outside of the transmission parts such as the gear 15 to play a protective role and prevent external substances from entering the transmission system. The rotating rod 14 is used to connect the gear 15. The gear 15 is a key component for power transmission. By meshing the lower teeth 9 and the upper teeth 12, the power conversion and transmission are realized to ensure the realization of the two-way stirring function. The hinge 21 connects the discharge cover 22 and the fermentation tank 1, so that the discharge cover 22 can be flexibly opened and closed, which is convenient for pouring in and out of manure. The discharge cover 22 can be opened and closed under the action of the hinge 21, and it is convenient to close the fermentation tank 1 during the fermentation process and open the discharge port when discharging with the action of the cover 5. The handle 23 is convenient for workers to hold and is used to pull the discharge cover 22 so that it can be easily opened and closed, thereby improving the convenience of operation.

[0032] Reference Figure 1 and Figure 4The pushing component includes a sliding groove 16, the bottom of the sliding groove 16 is fixedly connected to the top of the bottom plate 4, the front side of the sliding groove 16 is fixedly connected to a motor 2 17, the output end of the motor 2 17 is fixedly connected to a threaded rod 18, the outer thread of the threaded rod 18 is threadedly connected to a slider 19, a connecting rod 20 is arranged between the slider 19 and the fermentation tank 1, the outer side of the slider 19 is slidably connected to the inside of the sliding groove 16, both ends of the threaded rod 18 are rotatably connected to the inside of the sliding groove 16, one end of the connecting rod 20 is hinged to the outer wall of the fermentation tank 1, and the other end of the connecting rod 20 is hinged to the top of the slider 19.

[0033] Specifically, the sliding groove 16 provides a motion track for the slider 19, ensuring that the slider 19 can slide smoothly therein, thereby driving the connecting rod 20 and the fermentation tank 1 to tilt. The motor 2 17 serves as a power source for tilting the fermentation tank 1, and drives the threaded rod 18 to rotate to achieve the tilting and resetting of the fermentation tank 1. The threaded rod 18 rotates under the drive of the motor 2 17, and through the threaded connection with the slider 19, the rotational motion is converted into the linear motion of the slider 19. The connecting rod 20 connects the slider 19 and the fermentation tank 1, acts as a bridge, and transmits the motion of the slider 19 to the fermentation tank 1, thereby achieving the tilting of the fermentation tank 1.

[0034] Working principle: Pull the handle 23 to open the discharge cover 22, pour the manure to be fermented into the fermentation tank 1, start the motor 16 to drive the rotating shaft 17 and the stirring frame 18 to rotate, and at the same time, the rotating shaft 17 drives the lower teeth 9 fixed thereto to rotate. Since the lower teeth 9 and the gear 15 are meshed and connected, the rotation of the lower teeth 9 drives the gear 15 to rotate at the same time. At the same time, since the gear 15 and the upper teeth 12 are meshed and connected, the rotation of the gear 15 will drive the upper teeth 12 to rotate in the opposite direction, and then drive the rotating shaft 2 10 and the stirring frame 2 11 to rotate in the opposite direction, so as to realize the two-way stirring of the manure during fermentation. Stir to make the manure ferment more fully. When the manure fermentation is completed, the fermented manure needs to be dumped out. At this time, the motor 2 17 is started to drive the threaded rod 18 to rotate. The rotation of the threaded rod 18 drives the slider 19 to slide along the inside of the sliding groove 16, and drives the connecting rod 20 hinged thereto to move, thereby pushing the fermentation tank 1 to start tilting through the connecting rod 20. When the connecting plate 20 pushes the fermentation tank 1 to a suitable tilt angle, hold the handle 23 to open the discharge cover 22 to dump the fermented manure out, which solves the problem that the viscosity of the fermented manure is high and it is not easy to discharge smoothly during discharge.
