Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry equipment, in particular to animal husbandry equipment with environmental protection function. Background Art

[0002] Application number 201820922302.8 provides a livestock breeding equipment with environmental protection function, including a breeding house, locking bolts and T-bolts. A fixed frame is fixed at the front end of the breeding house, and there are two fixed frames in total. A ventilator, a zeolite layer and an activated carbon fiber layer are fixed in the two fixed frames. A heater and a control box are fixed on the side of the breeding house. An inverter, a controller and an energy storage battery are fixed in the control box. A top cover is installed on the top of the breeding house. The surface of the top cover is covered with solar panels, and an insulation integrated panel and a lightweight partition panel are provided in the gap of the breeding house.

[0003] The device uses a ventilator to promptly remove odors from the breeding room, ensuring good ventilation and providing a good living environment for livestock, while also achieving energy conservation and environmental protection. However, the gases emitted by ruminant livestock, such as cattle and sheep, contain large amounts of methane. For example, a cow can expel 800 to 1,000 liters of gas daily through farting and burping, of which approximately 30% is methane. This gas, if released into the atmosphere simply by removing the odor, could contribute to the greenhouse effect. Utility Model Content

[0030] Example 1:

[0031] See also Figure 1-4 The present invention describes the above technical solution in detail through the following embodiments:

[0032] A livestock breeding equipment with environmental protection function, comprising:

[0033] The frame 1 includes a floor 11 , a ceiling 14 is mounted on the top surface of the floor 11 through columns 12 , and an exhaust pipe 15 is welded to the center of the top surface of the ceiling 14 .

[0034] The columns 12 are welded and mounted on the top surface of the floor 11. The gas exhausted by cattle and sheep contains a large amount of methane gas. The density of methane is lower than that of air, so the methane gas will float upward. The gas produced by livestock can be blocked by the ceiling 14 and then discharged from the exhaust pipe 15.

[0035] The floor 11 is provided with a plurality of through holes.

[0036] The through holes on the floor 11 can facilitate the discharge of animal feces and the discharge of sewage during flushing. A feces collection device can be connected under the floor 11, which is not shown in the figure.

[0037] A top beam 13 is fixedly mounted on the top of the column 12 by bolts, and a roof 14 is fixedly mounted above the top beam 13 by bolts, with an outer edge of the roof 14 being lower than the top beam 13 .

[0038] The outer edge of the ceiling 14 is lower than the top beam 13 , which can improve the collection effect of exhaust gas and reduce the escape of exhaust gas from the outside of the ceiling 14 .

[0039] The fence 2 is installed above the floor 11 and between the pillars 12.

[0040] The fence 2 is used to limit the range of livestock activities.

[0041] The fence 2 includes three first fences 21, which are fixed by bolts between two adjacent upright posts 12. A gap is left between the bottom of the first fence 21 and the floor 11.

[0042] The first fence 21 is used to restrict the movement of livestock.

[0043] The fence 2 further includes a fence gate 22 , one end of which is rotatably connected to the post 12 via a rotating element 23 , and the other end of which is connected to the post 12 via a lock 24 .

[0044] The rotating element 23 can be a hinge or a hinge, and the fence gate 22 can be rotated around the column 12 by the rotating element 23. The lock 24 is used to limit the rotation of the fence gate 22. When the fence gate 22 is opened, it is used for livestock to pass through.

[0045] The preliminary collecting device 3 includes a primary collecting barrel 31 , which is connected to the exhaust pipe 15 and is used to collect the gas discharged from the exhaust pipe 15 .

[0046] The primary collection barrel 31 can be a metal barrel or a plastic barrel.

[0047] An air inlet 32 ​​is provided at the center of the bottom of the primary collecting barrel 31 . The exhaust pipe 15 is fixedly connected to the air inlet 32 ​​by bolts. A third methane detection device 37 is threadedly installed below the air inlet 32 ​​.

[0048] After the exhaust gas enters the exhaust pipe 15 , it can enter the primary collection barrel 31 through the air inlet 32 ​​. The third methane detection device 37 can be a well-known methane detector. The third methane detection device 37 is used to detect the methane concentration in the gas entering the primary collection barrel 31 .

[0049] A second methane detection device 36 is threadedly mounted on the center of the top of the primary collecting barrel 31 .

[0050] The second methane detection device 36 can be a well-known methane detector. The second methane detection device 36 is used to detect the methane concentration of the gas at the top of the primary collection barrel 31.

[0051] A ventilation pipe 33 is welded to the bottom of the primary collecting barrel 31 and located on the left side of the air inlet 32. The ventilation pipe 33 is connected to the external atmosphere. A first methane detection device 35 is threadedly installed on the ventilation pipe 33.

[0052] Because methane gas has a lower density than air, methane in the exhaust gas entering primary collection barrel 31 concentrates at the top of primary collection barrel 31, displacing air, allowing the air to be discharged through ventilation pipe 33 at the bottom. A first methane detector 35 can be a well-known methane detector. The first methane detector 35 is used to detect the methane concentration in the exhaust gas from ventilation pipe 33. When the first methane detector 35 detects that the methane concentration in the exhaust gas from ventilation pipe 33 reaches a set value, it indicates that the majority of the gas in primary collection barrel 31 is methane.

[0053] An exhaust pipe 34 is welded to the bottom of the primary collecting barrel 31 and to the right of the air inlet 32 ​​. The head of the exhaust pipe 34 is inserted into the interior of the primary collecting barrel 31 and extends upward.

[0054] The head of the air extraction pipe 34 is close to the inner top surface of the primary collection barrel 31 , and a gap is left between the head of the air extraction pipe 34 and the inner top surface of the primary collection barrel 31 .

[0055] The secondary collection device 4 includes an air pump 41, which is connected to a secondary collection tank 43 through a drying filter tank 42. The air pump 41 is used to pump out the gas collected in the primary collection barrel 31, and the gas is filtered by the drying filter tank 42 and then collected by the secondary collection tank 43.

[0056] The drying filter tank 42 is used to filter moisture and odor in the exhaust gas, and a desiccant and a deodorant can be set in the drying filter tank 42. The secondary collection tank 43 is used to store methane gas for subsequent processing.

[0057] The air extraction pump 41 is connected to the tail end of the air extraction pipe 34 through a pipeline.

[0058] The air extraction pump 41 is a well-known gas pump with explosion-proof function, and can pump out the methane gas in the primary collection barrel 31 through the air extraction pipe 34 .

[0059] When the operator of this embodiment uses this device, the lighter methane in the gas produced by livestock burping and farting will float up, and the rising gas will be blocked by the ceiling 14 and then enter the exhaust pipe 15.

[0060] After the exhaust gas enters the exhaust pipe 15 , it can enter the primary collection barrel 31 through the air inlet 32 ​​.

[0061] Because methane gas has a lower density than air, methane in the exhaust gas entering primary collection barrel 31 concentrates at the top of primary collection barrel 31, displacing air, allowing the air to be discharged through ventilation pipe 33 at the bottom. A first methane detector 35 can be a well-known methane detector. The first methane detector 35 is used to detect the methane concentration in the exhaust gas from ventilation pipe 33. When the first methane detector 35 detects that the methane concentration in the exhaust gas from ventilation pipe 33 reaches a set value, it indicates that the majority of the gas in primary collection barrel 31 is methane.

[0062] At this time, the vacuum pump 41 is started, and the methane gas in the primary collection barrel 31 is pumped out through the vacuum pipe 34. The pumped out gas is filtered by the drying filter tank 42 and then collected by the secondary collection tank 43.

[0063] When both the second methane detection device 36 and the third methane detection device 37 detect that the methane gas concentration is insufficient, the air extraction pump 41 stops working and the primary collection barrel 31 performs a second round of gas collection.
