Description

Technical Field

[0001] This utility model relates to the field of ventilation technology, and in particular to a ventilation system for pigsties. Background Technology

[0002] In modern animal husbandry, the air quality inside pigsties directly affects the health and growth rate of pigs. However, due to pig excrement and respiration, large amounts of ammonia, hydrogen sulfide, and other harmful gases often accumulate in pigsties. These gases not only affect the pigs' growth environment but may also induce respiratory diseases and reduce farming efficiency. Traditional pigsty ventilation systems often rely on simple mechanical exhaust devices, which suffer from uneven ventilation, high energy consumption, and direct emission of untreated exhaust gases, resulting in significant energy loss during the farming process and ineffective air pollution control.

[0003] Therefore, we propose a pigsty ventilation system to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a ventilation system for pigsties.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pigsty ventilation system, comprising a pad, a tank, and a cylindrical shell. A negative pressure pump and a tank are respectively provided on the upper surface of the pad. The suction end of the negative pressure pump is provided with a suction pipe, and suction heads are provided at equal intervals on the suction pipe. The discharge end of the negative pressure pump is connected to the air inlet of the tank through a connecting pipe. A mesh cylinder is provided inside the tank, and the mesh cylinder is filled with activated carbon. An exhaust pipe is provided at the air outlet of the mesh cylinder. A dust collection assembly is provided at the bottom of the tank. A heat exchange pipe is connected in series on the exhaust pipe, and the heat exchange pipe is located inside the cylindrical shell.

[0006] Preferably, the dust collection assembly consists of a collection tank, a cap, and a collection pipe, wherein the collection pipe is located at the bottom opening of the tank and passes through the pad.

[0007] Preferably, the cap is threaded at the bottom end of the collecting pipe, and the top opening of the collecting tank is engaged with the lower surface of the cap.

[0008] Preferably, the air outlet of the cylinder shell is provided with a panel, and the panel is provided with mounting holes at equal intervals.

[0009] Preferably, the top of the tank has a circular hole that matches the mesh tube, and the mesh tube is movably inserted into the circular hole.

[0010] Preferably, a screw cap is movably fitted onto the discharge pipe, the screw cap being threadedly engaged with the upper outer wall of the tank, and the bottom end of the discharge pipe being pressed into contact with the top end of the mesh cylinder.

[0011] Preferably, the suction pipe is provided with hanging members at equal intervals, and the hanging members are provided with mounting holes symmetrically.

[0012] Preferably, the lower surface of the pad is provided with four legs, and the four legs are arranged in a rectangular array on the lower surface of the pad.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In use, the ventilation system of this utility model can be set up inside the pigsty. The suction pipe is suspended and installed above the internal space of the pigsty through the hanging parts, and the cylinder shell is set at the air inlet on the lower side of the pigsty through the panel.

[0015] Connect to an external power source to activate the negative pressure pump. The negative pressure pump draws air from inside the pigsty through the suction head. The air enters the negative pressure pump through the suction pipe and then enters the tank through the connecting pipe. At this time, the air inside the pigsty passes through the activated carbon inside the mesh cylinder and enters the discharge pipe. During this process, solid impurities carried in the air inside the pigsty are filtered by the mesh cylinder, and odors carried in the air inside the pigsty are filtered by the activated carbon. The impurities trapped by the mesh cylinder enter the collection tank through the collection pipe under the action of gravity.

[0016] At this time, the pigsty is under negative pressure. Fresh air from the outside enters the pigsty through the cylinder shell. At the same time, the treated air enters the heat exchange tube and exchanges heat with the fresh air in the cylinder shell that is about to enter the pigsty. The hot air discharged and the fresh air entering exchange heat, reducing heat loss, thereby reducing winter heating energy consumption and improving energy utilization.

[0017] This invention can purify and filter air before releasing it. The mesh cylinder is responsible for trapping suspended solid particles in the air, while the activated carbon effectively adsorbs odors and harmful gases in the air, significantly improving the air quality inside the pigsty, reducing the impact of harmful gases on the health of pigs, and treating the discharged harmful gases to avoid environmental pollution.

[0018] The exhaust gas exchanges heat with the fresh air that is about to enter the pigsty before entering the outside, reducing heat loss. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] like Figures 1-5 As shown, the present invention proposes a pigsty ventilation system, including a pad plate 2, a tank body 4, and a cylindrical shell 8. A negative pressure pump 3 and a tank body 4 are respectively provided on the upper surface of the pad plate 2. The suction end of the negative pressure pump 3 is provided with a suction pipe 7, and suction heads 9 are provided at equal intervals on the suction pipe 7. The discharge end of the negative pressure pump 3 is connected to the air inlet of the tank body 4 through a connecting pipe 13. A mesh cylinder 12 is provided inside the tank body 4, and the mesh cylinder 12 is filled with activated carbon. The air outlet of the mesh cylinder 12 is provided with a discharge pipe 6. A dust collection component is provided at the bottom of the tank body 4. A heat exchange pipe 16 is connected in series on the discharge pipe 6 and is located inside the cylindrical shell 8.

[0029] Based on Example 1:

[0030] In use, the ventilation system of this utility model can be installed inside the pigsty and connected to an external power source to make the negative pressure pump 3 work. The negative pressure pump 3 draws air from inside the pigsty through the suction head 9. The air inside the pigsty enters the negative pressure pump 3 through the suction pipe 7, and then enters the tank 4 through the connecting pipe 13. At this time, the air inside the pigsty passes through the activated carbon inside the mesh cylinder 12 and enters the discharge pipe 6. During this process, solid impurities carried in the air inside the pigsty are filtered by the mesh cylinder 12, and odors carried in the air inside the pigsty are filtered by the activated carbon. The impurities trapped by the mesh cylinder 12 enter the collection tank 11 through the collection pipe 15 under the action of gravity.

[0031] At this time, the pigsty is under negative pressure. Fresh air from the outside enters the pigsty through the shell 8. At the same time, the treated air enters the heat exchange tube 16 and exchanges heat with the fresh air in the shell 8 that is about to enter the pigsty. The hot air discharged and the fresh air entering exchange heat, reducing heat loss, thereby reducing winter heating energy consumption and improving energy utilization.

[0032] Example 2

[0033] like Figures 1-5 As shown, the present invention proposes a pigsty ventilation system. Compared with Embodiment 1, this embodiment further includes: a panel 17 is provided at the air outlet of the cylinder shell 8, and mounting holes are equally spaced on the panel 17; hanging members 10 are equally spaced on the suction pipe 7, and mounting holes are symmetrically provided on the hanging members 10; the suction pipe 7 is suspended and installed above the internal space of the pigsty through the hanging members 10; and the cylinder shell 8 is placed at the air inlet on the lower side of the pigsty through the panel 17.

[0034] The dust collection assembly consists of a collection tank 11, a cover 14, and a collection pipe 15. The collection pipe 15 is located at the bottom opening of the tank body 4 and passes through the pad 2. The cover 14 is threaded onto the bottom end of the collection pipe 15. The top opening of the collection tank 11 is snapped onto the lower surface of the cover 14. When the impurities stored in the collection tank 11 reach a certain level, personnel can rotate the cover 14 to separate it from the collection pipe 15, and then pull the cover 14 off the collection tank 11 to clean the impurities inside the collection tank 11.

[0035] The top of the tank 4 has a round hole that matches the mesh cylinder 12. The mesh cylinder 12 is movably inserted into the round hole. A screw cap 5 is movably fitted onto the discharge pipe 6. The screw cap 5 is threadedly engaged with the upper outer wall of the tank 4. The bottom end of the discharge pipe 6 is pressed against the top end of the mesh cylinder 12. At the same time, the part of the discharge pipe 6 corresponding to the screw cap 5 is designed as a flexible hose. With the cooperation of the above structure, when needed, the screw cap 5 can be rotated to move the screw cap 5 away from the tank 4, and the discharge pipe 6 can be removed from the tank 4. At this time, the mesh cylinder 12 can be pulled out from the tank 4 for easy replacement of the activated carbon inside.

[0036] Furthermore, a filter screen can be installed at the air inlet of the suction head 9 and the cylinder shell 8 to filter the air entering the negative pressure pump 3 and the pigsty.

[0037] Furthermore, in winter, an insulation layer can be wrapped around the gas pipeline of the ventilation system to reduce heat loss during gas transportation.

[0038] The lower surface of the pad 2 is provided with four legs 1, and the four legs 1 are arranged in a rectangular array on the lower surface of the pad 2.

[0039] It should be noted that the structure of the negative pressure pump 3 is a mature existing technology, and its working principle and internal structure are known to those skilled in the art. This utility model only utilizes its function and does not improve its internal structure. Therefore, it will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0040] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
