Description

Technical Field

[0001] The utility model relates to the technical field of rabbit breeding related equipment, in particular to a biogas pool for harmless treatment of rabbit excrement. Background Art

[0002] In the process of rabbit breeding, a large amount of rabbit manure will be produced. If it is not cleaned up in time, it will pollute the breeding environment and easily cause the rabbits to get sick. Because rabbits like a clean and dry environment, breeders need to clean the rabbit house frequently. The cleaned rabbit manure can be fermented or made into fertilizer. The most common fermentation method is biogas fermentation. The gas produced by fermentation can be used as fuel, and the fermented solid can be used as fertilizer. However, the existing biogas pool has only one fermentation chamber. When the pipeline is blocked, the rabbit manure cannot be processed and accumulates, affecting the health of the rabbits. Utility Model Content

[0003] The utility model aims to provide a biogas tank for harmless treatment of rabbit excrement. The biogas tank has two fermentation chambers which can be switched for use, thereby ensuring that the biogas tank can continuously collect rabbit excrement and keep the rabbit house environment clean.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a biogas pool for harmless treatment of rabbit manure, including a fermentation tank, a feed chamber and a water pressure chamber, an air outlet pipe is arranged on the top of the fermentation tank, a partition is arranged in the fermentation tank, and the partition divides the fermentation tank into two fermentation chambers; a feed branch pipe and a pressure regulating branch pipe are arranged on each fermentation chamber, a feed main pipe is arranged at the bottom of the feed chamber, the feed main pipe is connected with the two feed branch pipes, and each feed branch pipe is provided with a feed valve; a pressure regulating main pipe is arranged at the bottom of the water pressure chamber, the pressure regulating main pipe is connected with the two pressure regulating branch pipes, and each pressure regulating branch pipe is provided with a pressure regulating valve.

[0005] Optionally, discharge pipes are provided at the bottoms of the two fermentation chambers.

[0006] Optionally, the diameter of the main feed pipe is smaller than the diameter of the branch feed pipe.

[0007] Optionally, the diameter of the main pressure regulating pipe is larger than the diameter of the branch pressure regulating pipe.

[0008] Optionally, a dehydration box and a desulfurization box are sequentially arranged on the gas outlet pipe.

[0009] The biogas digester for harmless treatment of rabbit manure of the utility model has the following advantages:

[0010] (1) Under normal circumstances, only one side of the fermentation chamber is in use, and the other side is in standby mode. When the pipeline on one side is blocked or there is insufficient space in the fermentation chamber, the fermentation chamber on the other side can be switched to process rabbit manure. The switching operation is simple and can ensure the continuity of rabbit manure treatment and the cleanliness of the rabbit house environment.

[0011] (2) The discharge pipe can discharge the fertilizer at the bottom of the fermentation chamber.

[0012] (3) The diameter of the main feed pipe is smaller than that of the branch feed pipe, and the diameter of the main pressure regulating pipe is larger than that of the branch pressure regulating pipe. This can reduce pipeline blockage and improve the operating stability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 It is a structural diagram of the fermentation room. DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings.

[0016] like Figure 1-Figure 2 As shown, a biogas tank for harmless treatment of rabbit manure includes a fermentation tank 1, a feed chamber 2 and a hydraulic chamber 3. An air outlet pipe 4 is arranged on the top of the fermentation tank 1, and a dehydration box 5 and a desulfurization box 6 are arranged on the air outlet pipe 4 in sequence. The dehydration box 5 and the desulfurization box 6 can process the produced gas so that it can be used as fuel better. A partition 7 is arranged in the fermentation tank 1. The height of the partition 7 is lower than the height of the fermentation tank 1. The partition 7 divides the fermentation tank 1 into two fermentation chambers 8. A feed branch pipe 9 and a pressure regulating branch pipe 12 are arranged on each fermentation chamber 8. The feed branch pipe 9 is located above the liquid level in the fermentation chamber 8, and the pressure regulating branch pipe 12 is located below the liquid level in the fermentation chamber 8. A feed main pipe 10 is arranged at the bottom of the feed chamber 2. The feed main pipe 10 is connected to the two feed branch pipes 9. The diameter of the feed main pipe 10 is smaller than the diameter of the feed branch pipe 9. A feed valve 11 is arranged on each feed branch pipe 9. A pressure regulating main pipe 13 is provided at the bottom of the hydraulic chamber 3, and the pressure regulating main pipe 13 is connected to two pressure regulating branch pipes 12. The diameter of the pressure regulating main pipe 13 is larger than that of the pressure regulating branch pipes 12, and a pressure regulating valve 14 is provided on each pressure regulating branch pipe 12. A discharge pipe 15 is provided at the bottom of the two fermentation chambers 8.

[0017] Under normal circumstances, only one side of the fermentation tank 1 is put into use, and the corresponding feed valve 11 and pressure regulating valve 14 are opened, while the fermentation tank 1 on the other side is in standby state, and the corresponding feed valve 11 and pressure regulating valve 14 are closed. The mixture of rabbit manure and rabbit urine enters the fermentation tank 1 from the feed box through the feed main pipe 10 and the feed branch pipe 9. Because the diameter of the feed main pipe 10 is smaller than the diameter of the feed branch pipe 9, if the rabbit manure is not blocked in the feed main pipe 10, then when entering the feed branch pipe 9, there will be no blockage, ensuring normal feeding. The decomposition and metabolism of various microorganisms in the fermentation tank 1 produce biogas, which can increase the pressure in the fermentation tank 1 and squeeze part of the liquid into the water pressure chamber 3 to adjust the pressure. If there is no blockage in the pressure regulating main pipe 13, then when the liquid enters the pressure regulating branch pipe 12, it is not easy to be blocked, ensuring normal pressure regulation. The biogas can be used as fuel, and the fermentation residue at the bottom of the fermentation tank 1 can be used as fertilizer and can be discharged through the discharge pipe 15.

[0018] When the pipeline on one side is blocked or the storage space of the fermentation chamber 8 is insufficient, the fermentation chamber 8 on the other side can be switched to process rabbit manure to ensure that the biogas digester can continue to collect rabbit manure without causing rabbit manure accumulation and keeping the rabbit house environment clean. During this period, the unusable fermentation chamber 8 can be repaired or processed to restore it to standby status as soon as possible.

[0019] The embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.
