Description

Technical Field

[0001] The utility model belongs to the technical field of garbage incineration, and more specifically relates to a fermentation tank for garbage incineration. Background Art

[0002] Currently, waste-to-energy plants use garbage to generate electricity. First, garbage is unloaded by truck into a fermentation tank. After a period of settling and fermentation, a crane and mechanical gripper load the fermented garbage into piles and transfer them to the incinerator for incineration and power generation. However, due to the decay and fermentation of the garbage, the humidity in the fermentation tank is high. If the fermented garbage is directly transferred to the incinerator, a large amount of water vapor will be present in the exhaust gas from the incineration, making subsequent waste gas treatment more difficult.

[0003] For example, patent application number CN202123442582.3 describes a garbage drying device for a waste incineration power plant, comprising a hot air supply assembly mounted on the side wall of a waste fermentation tank for providing heated air, an exhaust assembly mounted near the bottom of the side wall of the waste fermentation tank and connected to the waste incineration power plant's exhaust gas treatment system, and a foldable and resetting air guide assembly mounted on the side wall of the waste fermentation tank at the exhaust port of the hot air supply assembly. This device can reduce the moisture content of waste to be fed into the waste incinerator.

[0004] Although the above-mentioned garbage drying device for a waste incineration power plant can reduce the moisture content of the garbage to be put into the waste incinerator, its fermentation efficiency is low. Utility Model Content

[0007] Preferably, the upper end of the push plate is provided with an arc surface which is higher in the middle and lower on both sides.

[0008] Preferably, the two stirring blades are spiral stainless steel plates.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0015] Specific embodiment 1: Please refer to Figure 1-2 A fermentation tank for waste incineration, comprising a fermentation tank 10; a cover 11 is clamped on the upper end of the fermentation tank 10; a feeding port 20 is fixedly connected to the upper end of the cover 11; a pair of motors 12 are fixedly provided on one side of the fermentation tank 10; the output ends of the two motors 12 are fixedly connected to stirring blades 19; a discharge pipe 13 is fixedly provided on one side of the fermentation tank 10; a filter 14 is clamped on the end of the discharge pipe 13 away from the fermentation tank 10; a pair of electric cylinders 15 are fixedly provided on the lower end of the inner side of the fermentation tank 10; the output ends of the pair of electric cylinders 15 are fixedly connected to the push plate 18; the fermentation tank 10 is fixedly provided with a pair of electric cylinders 15. The inner side of the pool 10 is fixedly connected to the fixed plate 17 at the lower end of the push plate 18; the upper end surface of the fixed plate 17 is fixedly connected to the heating block 16; the fermentation pool 10 is rotatably connected to the flip door 21 on the upper side of the push plate 18; by setting the heating block 16, the heating block 16 is used to heat the water flow in the garbage, and at the same time, the heating block 16 is used to heat the air between the fixed plate 17 and the push plate 18 to dry the garbage and improve the fermentation efficiency; by setting the electric cylinder 15, the output end of the electric cylinder 15 is fixedly connected to the push plate 18, and the push plate 18 is used to push the garbage, thereby accelerating the outflow of water in the garbage and improving the fermentation efficiency.

[0016] See also Figure 2 The upper end of the push plate 18 is provided with an arc surface with a high middle and low sides.

[0017] See also Figure 2 , the two stirring blades 19 are spiral stainless steel plates; by setting the stirring blades 19 to spiral stainless steel plates, it does not occupy too much space inside the fermentation tank 10, thereby improving the efficiency of garbage disposal.

[0018] During operation, garbage is put into the feeding port 20, and then the motor 12 is started. The output end of the motor 12 drives the stirring blade 19 to rotate, and the fan blades of the stirring blade 19 drive the garbage to rotate, so that the gaps between the garbage are constantly changing during the continuous turning of the garbage, causing the moisture in the garbage to gradually flow to the upper end surface of the push plate 18, and finally the moisture in the garbage flows down from the push plate 18, and the heating block 16 is started. The heating block 16 heats the moisture in the garbage, and then the water flows out from the discharge pipe 13. When the heating block 16 is continuously turned on, the air between the push plate 18 and the fixed plate 17 is heated, and the water is discharged from the discharge pipe 13, filtered through the filter 14, and the garbage is left inside the fermentation tank 10;

[0019] When there is too much garbage and the stirring blades 19 alone cannot effectively turn it over, the electric cylinder 15 is started. The output end of the electric cylinder 15 drives the push plate 18 to lift up the garbage. After the garbage is lifted, it is stirred in conjunction with the stirring blades 19. Then the output end of the electric cylinder 15 is quickly retracted, so that the shaking of the push plate 18 can filter the water in the garbage from the push plate 18. While increasing the flow of water, the push plate 18 is used to continuously adjust the flow of water in the garbage so that it gradually flows onto the upper end surface of the fixed plate 17.

[0020] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
