DETAILED DESCRIPTION

[0025] The utility model is further explained by the following embodiment and example, and the mode of the utility model includes but is not limited to the following embodiment.

[0026] As Figures 1-3 As shown in the utility model provides dairy farm manure collection and anaerobic fermentation device, including: U-shaped base 1, base 1 top is equipped with fermentation tank 2, and the top of fermentation tank 2 is equipped with sealing cover 3, and the manure produced by dairy farming is sent into fermentation tank 2 to carry out sealed anaerobic fermentation, and the bottom of fermentation tank 2 is equipped with lifting plate 6, and sealing ring is installed between lifting plate 6 and the inner wall of fermentation tank 2, and a plurality of hydraulic cylinders 7 are installed in base 1, and the top end of hydraulic cylinder 7 extends into fermentation tank 2 and is connected with lifting plate 6, when using, the manure produced by dairy farming is sent into fermentation tank 2 to store, according to the height of manure in tank, start hydraulic cylinder 7, make its output shaft elongation, then make lifting plate 6 rise, make the manure in fermentation tank 2 rise, make the top of manure close to the top of fermentation tank 2, then use sealing cover 3 to seal fermentation tank 2, make the manure in fermentation tank 2 can anaerobic fermentation, because of the rise of lifting plate 6, the air (oxygen) content in fermentation tank 2 reduces, then make the anaerobic bacteria in manure grow better, then improve fermentation speed. When the manure fermentation is finished, open sealing cover 3, extract the upper liquid in tank, then raise lifting plate 6, make the top of precipitate flush with the top of fermentation tank 2, can conveniently use excavator to take out the precipitate in tank and load the car, also can wait for the precipitate in tank to dry, then use excavator to take out the precipitate and load the car, it is worth mentioning that with the continuous taking out of precipitate, lifting plate 6 is driven to rise synchronously, makes the precipitate rise, facilitates the excavation of excavator.

[0027] By setting base 1, fermentation tank 2, sealing cover 3, lifting plate 6 and hydraulic cylinder 7, the manure in dairy farm can be collected and anaerobic fermentation, the size of the storage space of fermentation tank 2 can be adjusted by driving lifting plate 6 to rise by hydraulic cylinder 7, the excess air in fermentation tank 2 is discharged, which is beneficial to the growth of anaerobic bacteria, thereby improving the fermentation speed, and it is also beneficial to taking out the fermentation product in tank.

[0028] Example 2:

[0029] As Figure 1As shown, a pressure relief valve 4 is installed on the sealing cover 3. When in use, a large amount of biogas will be generated during fermentation in the fermentation tank 2, which will increase the air pressure in the fermentation tank 2. When the air pressure increases to a certain level, the excess gas in the tank is discharged through the pressure relief valve 4 to prevent the pressure in the tank from being too high, which may cause damage to the device.

[0030] By installing a pressure relief valve 4 on the sealing cover 3, excess gas in the tank can be discharged, the gas pressure in the tank can be reduced, and the safety of the device can be improved.

[0031] Example 3:

[0032] like Figure 1 As shown, a connecting pipe 5 is installed on the sealing cover 3, and one end of the connecting pipe 5 is connected to a biogas lamp or other biogas-using equipment. These devices are used to continuously consume the biogas in the fermentation tank 2, reduce the air pressure in the tank, and enable the device to be used safely. It is worth noting that a pressure gauge is installed on the connecting pipe 5, and biogas can be used for daily use within the pressure range.

[0033] By installing the connecting pipe 5 on the sealing cover 3, biogas can be conveniently utilized for domestic use, which can be beneficial to energy saving, reduce the air pressure in the fermentation tank 2, and improve the safety of the device.

[0034] Example 4:

[0035] like Figure 3 As shown, a sealing belt 8 is installed around the bottom of the fermentation tank 2. When the lifting plate 6 is lowered to the lowest position, its bottom is pressed against the sealing belt 8, so that a second seal is formed between the bottom of the fermentation tank 2 and the lifting plate 6, thereby improving the sealing performance of the lifting plate 6.

[0036] By installing the sealing belt 8 around the bottom of the fermentation tank 2, the sealing performance between the lifting plate 6 and the fermentation tank 2 can be improved.

[0037] Example 5:

[0038] like Figure 3 As shown, temperature sensors 9 are installed at multiple heights in the fermentation tank 2, and multiple circulation pipes 10 are pre-buried in the side wall of the fermentation tank 2. The circulation pipe 10 is divided into two parts, one part is connected to the cooling water equipment, and the other part is connected to the hot water equipment. When in use, in order to ferment the bacteria in the fermentation tank 2 at a suitable temperature, the temperature sensor 9 detects the temperature in the tank. When the temperature in the tank is low, the hot water equipment pumps hot water (60-65°C) into a part of the circulation pipe 10 to heat the fermentation tank 2, so that the fermentation tank 2 is heated to a suitable fermentation temperature range. When the temperature in the tank is high, the cooling water equipment pumps cold water (10-15°C) into the other part of the circulation pipe 10 to cool the fermentation tank 2, so that the fermentation tank 2 is cooled to a suitable fermentation temperature range.

[0039] By installing temperature sensor 9 and circulating pipe 10 in fermentation tank 2, the temperature of fermentation tank 2 can be controlled to keep the temperature within a suitable temperature range, thereby facilitating fermentation.

[0040] Embodiment 6:

[0042] By installing lifting lug 11 on the four corners of the sealed cover 3, the sealed cover 3 can be easily hoisted.

[0043] Embodiment 7:

[0044] As shown in the sealed cover 3 of the four corners of the installation of the lifting lug 11, in use, the use of wire rope connecting lifting lug 11, can be easily sealed cover 3 hoisted. Figures 1-2

[0045] By installing lifting lug 11 on the four corners of the sealed cover 3, the sealed cover 3 can be easily hoisted.

[0046] Working principle: in use, the manure produced by the dairy cattle is sent into the fermentation tank 2 for storage, according to the height of the manure in the tank, the hydraulic cylinder 7 is started to make its output shaft elongated, thereby making the lifting plate 6 elevated, making the manure in the fermentation tank 2 elevated, making the top of the manure close to the top of the fermentation tank 2, then using the sealed cover 3 to seal the fermentation tank 2, so that the manure in the fermentation tank 2 can be anaerobic fermentation, due to the elevation of the lifting plate 6, the air (oxygen) content in the fermentation tank 2 is reduced, thereby making the anaerobic bacteria in the manure grow better, thereby improving the fermentation speed.

[0047] When the manure is fermented, the sealed cover 3 is opened, the upper layer liquid in the tank is extracted, the lifting plate 6 is elevated, the top of the sediment is flush with the top of the fermentation tank 2, the excavator or the manure suction vehicle can be used to take out the sediment in the tank, or the sediment can be dried and then taken out by the excavator, it is worth mentioning that with the continuous taking out of the sediment, the lifting plate 6 is simultaneously driven to elevate, making the sediment elevated, facilitating the excavation.​​
