[0002] Fermentation refers to the process in which people use the life activities of microorganisms under aerobic or anaerobic conditions to prepare the microorganisms themselves, or directly produce metabolites or secondary metabolites. Fermentation is sometimes also written as "酦酵", and its definition varies according to different usage occasions. Usually, the so-called fermentation mostly refers to a certain decomposition process of organisms for organic matter;

[0003] For the treatment of organic solid waste in villages and towns, aerobic fermentation is usually adopted to produce organic fertilizers for recycling.

[0004] When the existing aerobic fermentation device for organic solid waste is in use, the fermentation liquid and the fermentation substances are likely to be unevenly mixed during internal stirring, which affects the fermentation efficiency. Moreover, the previous fermentation substances are often not discharged cleanly before each fermentation, and they are likely to adhere to the inner wall of the tank body, affecting the next fermentation. Therefore, it does not meet the existing requirements, and for this reason, we propose an aerobic fermentation device for organic solid waste in villages and towns. Content of the Utility Model

[0005] The purpose of the utility model is to provide an aerobic fermentation device for organic solid waste in villages and towns, so as to solve the problems raised in the above background technique that when the aerobic fermentation device for organic solid waste is in use, the fermentation liquid and the fermentation substances are likely to be unevenly mixed during internal stirring, which affects the fermentation efficiency, and the previous fermentation substances are often not discharged cleanly before each fermentation, and they are likely to adhere to the inner wall of the tank body, affecting the next fermentation.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an aerobic fermentation device for organic solid waste in villages and towns, including a tank body, four support frames are fixedly installed at the top end of the tank body, the end of the support frame is fixedly connected with a support plate, lifting cylinders are fixedly installed at the four corner positions of the top end of the support plate, the output ends of the lifting cylinders are fixedly connected with a pushing plate, a connecting ring platform is movably installed at the bottom end of the pushing plate, four sector plates are fixedly installed on the outer surface of the connecting ring platform, and a plurality of water spray heads facing the inner wall of the tank body are arranged at the bottom ends of the sector plates.

[0008] Preferably, four U-shaped stirring rods are fixedly installed on the outer surface of the rotating shaft, and a spiral scraper is fixedly installed between each of the four U-shaped stirring rods. The spiral scraper is in contact with the inner wall surface of the tank. Four bottom stirring rods are fixedly installed on the surface of the rotating shaft near the bottom of the tank. The surface of the bottom stirring rod is in contact with the inner wall surface of the tank.

[0009] Preferably, the inner surface of the connecting ring platform is provided with four positioning lifting grooves, and the outer surface of the rotating shaft is fixedly installed with four positioning lifting rods, all of which are slidably inserted into the interior of the positioning lifting grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the cooperation of a U-shaped stirring rod and a bottom stirring rod, enables the device to fully stir the solid waste inside the tank during use, thereby improving its fermentation efficiency and preventing some solid waste from accumulating at the bottom of the tank and becoming impossible to move. Furthermore, the spiral scraper scrapes the inner wall of the tank, allowing the device to stir during use and, after fermentation, scrape away any residual products adhering to the inner wall surface, preventing them from affecting the next use of the device.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 An embodiment of this utility model provides an aerobic fermentation device for organic solid waste in villages and towns, comprising a tank 1, four support frames 3 fixedly installed at the top of the tank 1, support plates 4 fixedly connected to the ends of the support frames 3, lifting cylinders 5 fixedly installed at the four corners of the top of the support plates 4, push plates 7 fixedly connected to the output ends of the lifting cylinders 5, connecting ring platforms 17 movably installed at the bottom of the push plates 7, four fan-shaped plates 8 fixedly installed on the outer surface of the connecting ring platforms 17, and multiple water spray heads 12 facing the inner wall of the tank 1 at the bottom of each fan-shaped plate 8.

[0022] By cooperating with the fan-shaped plate 8 and the spray head 12, when the device needs to be cleaned after fermentation, the output end can be driven down by the lifting cylinder 5, which in turn pushes the push plate 7 down, thereby pushing the connecting ring platform 17 down. At this time, the connecting ring platform 17 will move along the direction of the rotating shaft 11. At this time, the fan-shaped plate 8 is located between the two U-shaped stirring rods 13. The U-shaped stirring rods 13 will not affect the descent of the fan-shaped plate 8 and the connecting ring platform 17. Subsequently, when the fan-shaped plate 8 descends, it will deliver water to the inside of the spray head 12 through the water supply pipe 9, thereby spraying water to clean the inner wall of the tank 1 through the spray head 12. With the scraping of the spiral scraper 14, the tank 1 can be automatically cleaned, avoiding the presence of residual products inside the tank 1 after fermentation.

[0023] A servo motor 6 is installed inside the bottom of the tank body 1. The output end of the servo motor 6 is connected to a rotating shaft 11 through a coupling. The rotating shaft 11 extends through the bottom of the tank body 1 to the top surface of the tank body 1 and is rotatably connected to the support plate 4.

[0024] Four U-shaped stirring rods 13 are fixedly installed on the outer surface of the rotating shaft 11. A spiral scraper 14 is fixedly installed between each of the four U-shaped stirring rods 13. The spiral scraper 14 is in contact with the inner wall surface of the tank body 1. Four bottom stirring rods 15 are fixedly installed on the surface of the rotating shaft 11 near the bottom of the tank body 1. The surface of the bottom stirring rods 15 is in contact with the inner wall surface of the tank body 1.

[0025] By cooperating with the U-shaped stirring rod 13 and the bottom stirring rod 15, the solid waste inside the tank 1 can be fully stirred during use, thereby improving the fermentation efficiency and preventing some solid waste from accumulating at the bottom of the tank 1 and becoming unmovable. Furthermore, by scraping the inner wall of the tank 1 with the spiral scraper 14, the device can not only stir during use but also scrape off any residual products adhering to the inner wall of the tank 1 after fermentation, thus preventing them from affecting the next use of the device.

[0026] The inner surface of the connecting ring platform 17 is provided with four positioning lifting grooves 10, and the outer surface of the rotating shaft 11 is fixedly installed with four positioning lifting rods 16, all of which are slidably inserted into the interior of the positioning lifting grooves 10.

[0027] By cooperating with the positioning lifting rod 16 and the positioning lifting groove 10, when the device sprays water through the spray head 12, the servo motor 6 can be activated to drive the rotating shaft 11 to rotate, which in turn drives the fan-shaped plate 8 to rotate simultaneously, so that the spray head 12 can rotate and spray water onto the inner wall of the tank 1, avoiding the situation of water spray dead angles.

[0028] A feed inlet 2 is provided on one side of the tank body 1, and the top of the rotating shaft 11 moves through the interior of the push plate 7 and the connecting ring platform 17. A discharge outlet is provided on one side of the tank body 1.

[0029] The top surface of the fan-shaped plate 8 is provided with a water supply pipe 9, which is connected to the inside of the spray head 12. One end of the water supply pipe 9 is connected to a water tank.

[0030] This aerobic fermentation device for organic solid waste in rural areas can fully stir the solid waste inside the tank 1 using the U-shaped stirring rod 13 and the bottom stirring rod 15, thereby improving the fermentation efficiency and preventing some solid waste from accumulating at the bottom of the tank 1 and becoming impossible to move. Simultaneously, the spiral scraper 14 stirs the waste, and after fermentation, it can scrape the inner wall of the tank 1 to remove any residual products adhering to the surface, preventing them from affecting the next use of the device.

[0031] When the device needs to be cleaned after fermentation, the output end can be lowered by the lifting cylinder 5, which in turn pushes the push plate 7 down, thereby pushing the connecting ring platform 17 down. At this time, the connecting ring platform 17 will move along the direction of the rotating shaft 11. At this time, the fan-shaped plates 8 are all located between the two U-shaped stirring rods 13. The U-shaped stirring rods 13 will not affect the descent of the fan-shaped plates 8 and the connecting ring platform 17. Subsequently, when the fan-shaped plates 8 descend, they will deliver water to the inside of the spray head 12 through the water supply pipe 9, thereby spraying water to clean the inner wall of the tank 1 through the spray head 12. With the scraping of the spiral scraper 14, the tank 1 can be automatically cleaned to avoid residual products inside the tank 1 after fermentation.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
