Description

Technical Field

[0001] The utility model belongs to the technical field of biogas slurry treatment, and in particular relates to a biogas slurry treatment device. Background Art

[0002] Biogas slurry is typically fermented from a mixture of cow, rabbit, and chicken manure. It is odorless and boasts a fertilizer efficiency over 10 times that of common chemical fertilizers. Its water-based properties allow it to be easily absorbed by plants, and unlike chemical fertilizers, excessive use of biogas slurry will not burn seedlings. As the fertilizer of choice for green, ecological farming, biogas slurry is commonly supplied directly to large supermarkets, star-rated hotels, and custom-made for individual customers. Biogas slurry has insect repellent and insecticide properties, with a mortality rate of over 90% for larvae and eggs, making it a green biopesticide. Even with controlled dosage, biogas slurry will not burn seedlings, a feature that distinguishes it from common chemical fertilizers.

[0003] During the fermentation process, the biogas slurry needs to ensure constant temperature anaerobic fermentation, and has high requirements on the fermentation environment. The fermentation of biogas slurry is generally achieved in a fermentation tank. The biogas slurry will emit heat during the fermentation process. Since the biogas slurry is generally static in the fermentation tank, the heat generated by the fermentation of the biogas slurry in the fermentation tank will be difficult to dissipate, causing the internal temperature of the biogas slurry to rise, which is not conducive to the fermentation of the biogas slurry. At the same time, the reactants in the static biogas slurry cannot be effectively turned over, further affecting the fermentation effect of the biogas slurry. Utility Model Content

[0019] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The present invention provides a biogas slurry treatment device. Figure 1-3 As shown, the biogas slurry treatment device includes: a plurality of support blocks 1, the top of the plurality of support blocks 1 is fixedly mounted with the same fermentation tank 2 for treating biogas slurry, and the fermentation tank 2 is fixedly mounted with a temperature sensor 14 and a controller; a water tank 3 for storing coolant is fixedly mounted on the bottom of the plurality of support blocks 1; a cooling pipe 4 rotatably mounted on the fermentation tank 2; a cooling mechanism assembled on the water tank 3 for cooling the biogas slurry; and a rotating mechanism mounted on the fermentation tank 2 for rotating the cooling pipe 4.

[0021] In this embodiment, when the device is used to ferment the biogas slurry, the temperature sensor 14 will continuously detect the temperature of the biogas slurry, and the detected temperature will be fed back to the controller. When the temperature fed back to the controller is high, the controller will start the cooling mechanism and the rotating mechanism according to the set requirements. The cooling mechanism will continuously transport the coolant in the water tank 3 to the cooling pipe 4, so that the cooling pipe 4 can cool the biogas slurry by the temperature of the coolant until the biogas slurry temperature drops to the optimal reaction temperature. When the coolant enters the cooling pipe 4, the rotating mechanism will also drive the cooling pipe 4 to rotate on the fermentation tank 2, so that the cooling pipe 4 can contact the biogas slurry more evenly, thereby improving the cooling effect. At the same time, it can also cause the cooling pipe 4 to stir the reactants in the biogas slurry, thereby improving the fermentation effect of the biogas slurry.

[0022] In a further preferred embodiment of the present invention, the cooling mechanism includes: a water pump 5 fixedly mounted on the top of the water tank 3, a water pumping pipe fixedly mounted on the water inlet end of the water pump 5, one end of the water pumping pipe extending to the interior of the water tank 3; a drain pipe 6 fixedly mounted on the drain end of the water pump 5, one end of the drain pipe 6 being sealed and rotatably connected to one end of the cooling pipe 4; a connecting pipe 7 fixedly mounted on the water tank 3, one end of the connecting pipe 7 being sealed and rotatably connected to one end of the cooling pipe 4.

[0023] In this embodiment, the cooling mechanism is used to cool the biogas slurry. When in use, the water pump 5 is started, and the water pump 5 will transfer the coolant in the water tank 3 to the drain pipe 6 through the pumping pipe. The drain pipe 6 will transfer the water to the cooling pipe 4, so that the cooling pipe 4 can cool the biogas slurry by the temperature of the coolant, thereby effectively cooling the biogas slurry to prevent the biogas slurry from affecting the fermentation effect due to excessive temperature. Then the coolant entering the cooling pipe 4 will flow into the water tank 3 from the connecting pipe 7, so that the coolant can be recycled.

[0024] In a further preferred embodiment of the present invention, the rotating mechanism includes: a shell 8 arranged on one side of the fermentation tank 2, and a motor 9 is fixedly installed on the inner wall of one side of the shell 8; a rotating shaft 10 rotatably installed on the shell 8, and one end of the rotating shaft 10 is fixedly connected to the output shaft of the motor 9; a first gear 11 fixedly installed on the rotating shaft 10; a second gear 12 fixedly sleeved on the cooling pipe 4, and the second gear 12 is meshed with the first gear 11.

[0025] In this embodiment, the rotating mechanism is used to rotate the cooling pipe 4. When in use, the motor 9 is started, the motor 9 will drive the rotating shaft 10 to rotate, the rotating shaft 10 will drive the first gear 11 to rotate, the first gear 11 will drive the second gear 12 to rotate, and the second gear 12 will drive the cooling pipe 4 to rotate on the fermentation tank 2. This not only allows the cooling pipe 4 to use coolant to evenly cool the biogas slurry, but also allows the cooling pipe 4 to stir the reactants in the biogas slurry, thereby improving the fermentation effect of the biogas slurry.

[0026] In a further preferred embodiment of the present invention, a pool cover 13 is provided on the top of the fermentation pool 2, and a plurality of handles are fixedly installed on the pool cover 13.

[0027] In this embodiment, the top of the fermentation tank 2 can be shielded by using the tank cover 13 to prevent pollutants from falling into the biogas slurry during the fermentation process. The use of multiple handles can facilitate the operator to open and close the tank cover 13.

[0028] In a further preferred embodiment of the present invention, a water adding pipe 15 is fixedly mounted on the water tank 3 , a hopper 16 is fixedly mounted on the top end of the water adding pipe 15 , and a filter screen 17 is provided inside the hopper 16 .

[0029] In this embodiment, by using the water adding pipe 15 and the hopper 16 in combination, the operator can easily and quickly add coolant to the water tank 3. By using the filter 17, the added coolant can be filtered and debris can be prevented from entering the water tank 3.

[0030] In a further preferred embodiment of the present invention, an observation port is provided on one side of the fermentation tank 2 , and an observation window 18 is fixedly mounted on the inner wall of the observation port.

[0031] In this embodiment, the use of the observation window 18 allows the operator to clearly see the actual situation in the fermentation tank 2 and conveniently observe the fermentation status of the biogas slurry.

[0032] In a further preferred embodiment of the present invention, a support base 19 is fixedly installed on one side of the fermentation tank 2 , and the bottom of the support base 19 is fixedly connected to the top of the shell 8 .

[0033] In this embodiment, by using the support base 19, the housing 8 can be stably fixed on one side of the fermentation tank 2, so that the motor 9 in the housing 8 can maintain good stability during operation.

[0034] To sum up, compared with the relevant technology, this solution can continuously detect the temperature of the biogas slurry during the fermentation process through the use of the temperature sensor 14. Through the use of the controller, the cooling mechanism and the rotating mechanism can be automatically started or shut down according to the temperature feedback from the temperature sensor 14. The cooling mechanism can continuously transport the coolant in the water tank 3 to the cooling pipe 4, so that the cooling pipe 4 can cool the biogas slurry by the temperature of the coolant until the biogas slurry temperature drops to the optimal reaction temperature. During the cooling process of the biogas slurry, the rotating mechanism will also drive the cooling pipe 4 to rotate on the fermentation tank 2, so that the cooling pipe 4 can stir the biogas slurry. This not only allows the cooling pipe 4 to evenly cool the biogas slurry with the coolant, but also allows the cooling pipe 4 to turn over the reactants in the biogas slurry, thereby improving the fermentation effect of the biogas slurry.
