Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0027] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or equipment.

[0028] The following is combined with Figure 1-Figure 2 This application is described in further detail.

[0029] refer to Figure 1-Figure 2The small organic fertilizer fermentation tank shown includes: a tank body 1 (the tank body can be a flange barrel: the outer shape is cylindrical, wide in the middle and narrow at the upper and lower ends, the maximum diameter of the tank body 1 is 51 cm, the minimum diameter is 40 cm, and the height is 80 cm), an exhaust gas treatment mechanism 2 and an aeration mechanism 3. The top of the tank body 1 is provided with a tank mouth, and a top cover 11 is detachably provided at the tank mouth; the exhaust gas treatment mechanism 2 is used to treat the exhaust gas discharged from the tank body 1; the aeration mechanism 3 is used to aerate the material in the tank body 1; the inner cavity of the tank body 1 is provided with a partition net 5, and the partition net 5 divides the inner cavity of the tank body 1 into two parts, upper and lower. The tank body 1 is provided with a discharge port above the partition net 5, the bottom of the discharge port is flush with the top surface of the partition net 5, and a baffle 6 is inserted at the discharge port. The tank body 1 is provided with a liquid discharge port 4 below the partition net 5. In this way, before adding the material into the tank body 1, the partition net 5 is first fixed to the inside of the tank body 1. In this embodiment, the partition net 5 is fixed to the lower middle part of the tank body 1. The partition net is circular and its diameter is lower than the maximum diameter of the tank body 1. The distance between the partition net 5 and the bottom of the tank body 1 is about 15 cm. At the same time, there is a blockage on the inner wall of the tank body 1 to facilitate the fixation of the partition net 5. Then the material is put into the tank body 1 from the tank mouth, and the material is added from the top of the tank body 1 (the top cover 11 is detachably connected to the tank body 1). During the fermentation of the material, the top cover 11 can be opened for manual mixing and temperature measurement. The discharge port 4 is close to the bottom of the tank body 1. After the fermentation of the material is completed or during the fermentation, the waste liquid generated by the fermentation inside the tank body 1 can be discharged at any time. A baffle 6 is provided at the discharge port (the baffle 6 can be plugged into the tank body 1 from top to bottom). After the fermentation of the material is completed, the discharge port is opened to discharge the fermented material. Since the bottom of the discharge port is flush with the top surface of the partition net 5, it is convenient to discharge the material from the tank body 1, thereby improving the production and processing efficiency.

[0030] refer to Figure 1 As shown, the waste gas treatment mechanism 2 includes a waste gas pipe 21, a waste gas treatment tank 22 and an outlet pipe 23. One end of the waste gas pipe 21 is connected to the waste gas treatment tank 22, and the other end is connected to the tank body 1. Waste gas treatment liquid is provided in the waste gas treatment tank 22. The end of the waste gas pipe 21 is located in the waste gas treatment liquid, and the outlet pipe 23 is provided at the top of the waste gas treatment tank 22. In this way, harmful gases such as hydrogen sulfide and ammonia will be generated during the composting process. The harmful gases are discharged from the tank body 1 into the waste gas treatment tank 22 through the waste gas pipe 21. After passing through the waste gas treatment liquid in the waste gas treatment tank 22 (generally a dilute sodium hydroxide solution), the harmful gases are discharged after being treated or absorbed by the waste gas treatment liquid through the waste gas pipe 21. Most of the harmful gases have a lower density than air. Therefore, the end of the waste gas pipe 21 away from the waste gas treatment tank 22 is provided on the top cover 11. This can ensure that the harmful gases are concentrated on the top of the tank body 1 and discharged through the waste gas pipe 21.

[0031] refer to Figure 1As shown, the aeration mechanism 3 includes an aeration pipe 31 and an aeration pump 32. One end of the aeration pipe 31 is connected to the tank body 1, and the other end is connected to the aeration pump 32. The aeration pump 32 can be turned on and off by setting a timer switch, and the aeration air volume and aeration frequency are adjusted according to the amount of material inside the tank body 1. The aeration pipe 31 is a hose structure, and a first pipe clamp 33 is provided at the hose on the outside of the tank body 1. When the aeration pump 32 is turned on, the first pipe clamp 33 is opened to let in air, and when the aeration pump 32 stops working, the first pipe clamp 33 is closed. On the one hand, this design minimizes internal heat loss, and on the other hand, it is conducive to the internal exhaust gas entering the exhaust gas treatment mechanism 2, and the end of the aeration pipe 31 away from the aeration pump 32 is located below the partition net 5, and the height of the end of the aeration pipe 31 away from the aeration pump 32 is higher than the height of the drain port 4 to prevent waste liquid from flowing back into the aeration pipe 31.

[0032] refer to Figure 1 As shown, a heating belt 7 is provided on the outside of the tank body 1. The location of the heating belt 7 does not require it to cover the entire tank body. It is only provided at the maximum diameter of the tank body 1. The outside of the tank body 1 is wrapped by the heating belt 7. The effective area of the heating belt 7 is not less than 30% of the surface area of the tank body 1 (excluding the upper and lower bottoms). The function of the heating belt 7 is to provide auxiliary heating in the initial stage of fermentation to increase the internal temperature. The heating belt 7 can be turned off in the middle and late stages of fermentation.

[0033] refer to Figure 1 As shown, a drain pipe 8 is provided at the drain port 4 , and a second pipe clamp 81 is provided on the drain pipe 8 , so that the drain pipe 8 can be opened and closed by the second pipe clamp 81 .

[0034] The working principle of the utility model is as follows: before adding the material into the tank body 1, the partition net 5 is first fixed inside the tank body 1, and then the material is put into the tank body 1 from the tank mouth, and the material is added from the top of the tank body 1. The discharge port 4 is close to the bottom of the tank body 1. After the fermentation of the material is completed or during the fermentation, the waste liquid generated by the fermentation inside the tank body 1 can be discharged at any time, and a baffle 6 is provided at the discharge port. After the fermentation of the material is completed, the discharge port is opened to discharge the fermented material. Since the bottom of the discharge port is flush with the top surface of the partition net 5, it is convenient to discharge the material from the tank body 1, thereby improving the production and processing efficiency;

[0035] Furthermore, during use of the present application, since the waste gas in the tank is discharged through the waste gas treatment mechanism 2, the harm to the human body when the worker is stirring is reduced.

[0036] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations directly derived or imagined by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the scope of protection of the present invention.
