Description

Technical Field

[0001] This invention relates to the field of next-generation breeding technology, and more specifically, to a ventilated pigsty. Background Technology

[0002] In traditional pigsties, continuous ventilation is necessary to maintain air quality, effectively reducing the chances of pigs getting sick and improving the overall environmental quality. However, during ventilation, some odor inevitably remains in the pigsty air. The gas displaced outside pollutes the surrounding air, causing odors and directly impacting external air quality. Furthermore, the higher the ventilation efficiency, the more severe the external odor problem becomes.

[0003] In view of the above, this application is hereby submitted. Summary of the Invention

[0004] The purpose of this invention is to provide a ventilated pigsty that ensures continuous air exchange while preventing odor leakage and continuously improving the air quality inside the pigsty.

[0005] The embodiments of the present invention are implemented as follows:

[0006] A ventilated pigsty includes: a pigsty body and an air exchange device, the air exchange device including a driver, a first cylinder and a second cylinder.

[0007] The first cylinder contains a first piston, which is reciprocated by a driver via a first piston rod. The first piston has a vent hole that passes through it, and the vent hole is equipped with a valve for controlling the unidirectional flow of air.

[0008] The end of the first cylinder furthest from the first stopper is connected to the second cylinder via a one-way valve. The inner diameter of the second cylinder is smaller than that of the first cylinder. There are multiple second cylinders, and each of the multiple second cylinders is connected to the first cylinder via a one-way valve.

[0009] A second piston is installed inside the second cylinder, and an elastic element abuts against the end of the second cylinder away from the one-way valve. A filter cartridge is fixedly connected to the outside of the second cylinder, extending axially along the second cylinder. The second cylinder and the filter cartridge are connected by a perforation located at the end of the second cylinder near the one-way valve. The filter cartridge is filled with deodorizing material and / or dust-collecting material.

[0010] An air outlet is provided at the end of the filter cartridge away from the perforation, and an air inlet is provided at the end of the first cylinder away from the one-way valve.

[0011] Furthermore, a drive ring is fitted onto the first piston rod, and the drive ring is slidably fitted onto the first piston rod. A second piston rod is fixedly connected to the side of the second piston away from the one-way valve, and the drive ring and the second piston rod are fixedly connected by a transmission rod.

[0012] The first stopper rod has an annular flange located on the side of the drive ring away from the first cylinder. When the first stopper rod moves into the first cylinder, the annular flange pushes the drive ring.

[0013] Furthermore, the ventilated pigsty also includes a controller. A trigger button is located on the side of the drive ring near the annular flange, and the trigger button is electrically connected to the controller.

[0014] When the first piston rod moves into the first cylinder, the annular flange pushes the drive ring and triggers the trigger button.

[0015] The controller monitors the duration of the trigger button being triggered during the movement of the first piston rod into the first cylinder. When the duration is less than the time threshold, the controller controls the driver to stop and sends a prompt to the administrator.

[0016] Furthermore, the central axis of the second cylinder is set parallel to the axis of the first cylinder, and the second cylinders are evenly spaced along the circumference of the first cylinder.

[0017] Furthermore, the second piston rod of the second cylinder is fixedly connected to the transmission rod.

[0018] Furthermore, when the air inlet is connected to the interior of the pigsty, the air outlet is connected to the exterior of the pigsty, and the filter cartridge is filled with deodorizing material.

[0019] Furthermore, when the air inlet is connected to the outside of the pigsty, the air outlet is connected to the inside of the pigsty, and the filter cartridge is filled with dust removal material.

[0020] The beneficial effects of the technical solutions in the embodiments of the present invention include:

[0021] The ventilated pigsty provided in this invention can effectively improve air purification by filling the filter cartridge with deodorizing / dust-removing materials. Although filling the filter cartridge directly affects the airflow and filtration speed within it, the large amount of gas supplied from the first cartridge to the second cartridge at one time cannot all be filtered directly. The unfiltered air pushes the second piston to compress the elastic element, thus temporarily storing the excess air in the second cartridge. The presence of the elastic element in the second cartridge ensures a relatively high gas pressure, which helps improve airflow and filtration speed, thereby offsetting the negative impact on purification speed.

[0022] After the first piston has pushed all the air from the first cylinder into the second cylinder, the actuator pushes the first piston to reset, thus drawing air back into the first cylinder in preparation for continuing to push air into the second cylinder. During the reset process of the first piston, under the action of the elastic element, the second piston can continue to push the air from the second cylinder into the filter cartridge for filtration, ensuring that the air in the second cylinder is fully filtered.

[0023] When the first piston starts supplying air into the second cylinder next time, the air in the second cylinder has been fully filtered out, and it can then continue to receive air from the first cylinder smoothly.

[0024] In this way, although the first piston intermittently supplies air to the second cylinder, the filter cartridge, in conjunction with the second cylinder, can continuously purify the air, effectively ensuring air purification efficiency. Furthermore, the air is pressurized throughout the entire purification process, allowing for the installation of thicker deodorizing / dust-removing materials, thus improving both purification effect and speed.

[0025] Overall, the ventilated pigsty provided by the embodiments of the present invention can ensure continuous air exchange while preventing odor leakage and continuously improving the air quality inside the pigsty. Attached Figure Description

For example, "parallel" simply means that its direction is more parallel than "perpendicular," not that the structure must be perfectly parallel, but that it can be slightly tilted.

[0040] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] Please refer to Figure 1 This embodiment provides a ventilated pigsty 1000, which includes a pigsty body 100 and an air exchange device 200. The air exchange device 200 includes a shell 300, a driver 400, a first cylinder 500 and a second cylinder 700.

[0042] The driver 400, the first cylinder 500, and the second cylinder 700 are all located inside the housing and distributed along the length of the housing. The first cylinder 500 is located between the second cylinder 700 and the driver 400, and the centerlines of the first cylinder 500 and the second cylinder 700 are arranged in parallel.

[0043] The first cylinder 500 is provided with a first piston 510, which is reciprocated by the driver 400 via a first piston rod 520. The first piston 510 has a vent hole 511 through which it passes, and the vent hole 511 is opened in the axial direction of the first cylinder 500. The vent hole 511 is provided with a valve 512 for controlling the unidirectional flow of air.

[0044] The end of the first cylinder 500 away from the first stopper 520 is connected to the second cylinder 700 through a one-way valve 600. Under the action of the one-way valve 600, air can enter the second cylinder 700 from the first cylinder 500, but air cannot enter the first cylinder 500 from the second cylinder 700.

[0045] The inner diameter of the second cylinder 700 is smaller than that of the first cylinder 500. There are multiple second cylinders 700, and all of them are connected to the first cylinder 500 through a one-way valve 600.

[0046] A second piston 710 is provided inside the second cylinder 700, and an elastic element 720 abuts against the end of the second cylinder 700 away from the one-way valve 600. A filter cartridge 800 is fixedly connected to the outside of the second cylinder 700, extending axially along the second cylinder 700. The second cylinder 700 and the filter cartridge 800 are connected by a through hole 810 located at the end of the second cylinder 700 near the one-way valve 600. The filter cartridge 800 is filled with deodorizing material 820 and / or dust-collecting material (not shown in the figure).

[0047] An air outlet 830 is provided at the end of the filter cartridge 800 away from the perforation 810, and an air inlet 530 is provided at the end of the first cylinder 500 away from the one-way valve 600.

[0048] When the first piston 510 moves toward the side where the actuator 400 is located, the valve 512 opens, and air enters the first cylinder 500 through the air inlet 530 and passes through the vent 511 into the space on the side of the piston closer to the second cylinder 700. When the first piston 510 moves toward the side where the second cylinder 700 is located, the valve 512 closes, and the first piston 510 can push the air in the first cylinder 500 into the second cylinder 700 through the one-way valve 600.

[0049] When air flows from the one-way valve 600 into the second cylinder 700, the air can enter the filter cartridge 800 through the perforation 810 and be filtered by the deodorizing material 820 / dust removal material to remove odors / dust.

[0050] This design allows the filter cartridge 800 to be filled with deodorizing material 820 / dust-removing material, effectively improving air purification. Although filling the filter cartridge 800 directly affects the airflow and filtration speed within it, the large volume of gas supplied from the first cartridge 500 to the second cartridge 700 at once cannot be filtered directly through the filter cartridge 800. The unfiltered air pushes the second piston 710 to compress the elastic element 720, temporarily storing the excess air in the second cartridge 700. The presence of the elastic element 720 in the second cartridge 700 ensures a relatively high gas pressure, further enhancing airflow and filtration speed within the filter cartridge 800, thus offsetting the negative impact on purification speed.

[0051] By setting up multiple second cylinders 700 to simultaneously receive air from the first cylinder 500, the air purification efficiency can be effectively improved, while ensuring that all the air discharged from the first cylinder 500 to the second cylinders 700 can be received.

[0052] After the first piston 510 has pushed all the air in the first cylinder 500 into the second cylinder 700, the driver 400 pushes the first piston 510 to reset, that is, to draw air back into the first cylinder 500 in preparation for continuing to push air into the second cylinder 700. During the reset process of the first piston 510, under the action of the elastic element 720, the second piston 710 can continue to push the air in the second cylinder 700 into the filter cartridge 800 for filtration, ensuring that the air in the second cylinder 700 is fully filtered.

[0053] When the first piston 510 starts supplying air into the second cylinder 700 next time, the air in the second cylinder 700 has been fully filtered out, and it can then continue to receive air supplied by the first cylinder 500 smoothly.

[0054] In this way, although the first piston 510 intermittently supplies air to the second cylinder 700, the filter cartridge 800, in conjunction with the second cylinder 700, can continuously purify the air, effectively ensuring air purification efficiency. Furthermore, throughout the entire purification process, the air is pressurized, facilitating the installation of a thicker deodorizing material 820 / dust-removing material, thus improving both purification effect and purification speed.

[0055] Overall, the ventilated pigsty 1000 provided in this embodiment can ensure continuous air exchange while preventing odor leakage and continuously improving the air quality inside the pigsty.

[0056] In this embodiment, specifically during implementation, when the air inlet 530 is connected to the interior of the pigsty body 100, the air outlet 830 is connected to the exterior of the pigsty body 100, and the filter cartridge 800 is filled with deodorizing material 820. When the air inlet 530 is connected to the exterior of the pigsty body 100, the air outlet 830 is connected to the interior of the pigsty body 100, and the filter cartridge 800 is filled with dust-removing material. This design allows for simultaneous purification of the air entering and leaving the pigsty body 100.

[0057] Furthermore, a drive ring 540 is fitted onto the first piston rod 520, and the drive ring 540 is slidably fitted onto the first piston rod 520. A second piston rod 730 is fixedly connected to the side of the second piston 710 away from the one-way valve 600. The second piston rod 730 extends from the end of the second cylinder 700 away from the one-way valve 600, and the drive ring 540 and the second piston rod 730 are fixedly connected by a transmission rod 550.

[0058] The first stopper rod 520 has an annular flange 560 located on the side of the drive ring 540 away from the first cylinder 500. When the first stopper rod 520 moves into the first cylinder 500, the annular flange 560 pushes the drive ring 540.

[0059] The central axis of each of the second cylinders 700 is parallel to the axis of the first cylinder 500, and the second cylinders 700 are evenly spaced along the circumference of the first cylinder 500. The second stopper rods 730 of each of the second cylinders 700 are fixedly connected to the transmission rods 550.

[0060] With this design, when the actuator 400 drives the first piston 510 through the first stopper rod 520 to push the air in the first cylinder 500 into the second cylinder 700, the first stopper rod 520 pushes the drive ring 540 through the annular flange 560, thereby pushing the second stopper rod 730 through the transmission rod 550. This causes the second piston 710 to move synchronously towards the end of the second cylinder 700 away from the one-way valve 600. This reduces the resistance encountered by the air when entering the second cylinder 700. Furthermore, since the second pistons 710 of multiple second cylinders 700 move synchronously, it can effectively ensure that the air is more evenly distributed among the second cylinders 700, keeping the amount of air in each second cylinder 700 balanced, thus improving the air purification effect and purification speed.

[0061] The ventilated pigsty 1000 also includes a controller (not shown in the figure). A trigger button 570 is provided on the side of the drive ring 540 near the annular flange 560, and the trigger button 570 is electrically connected to the controller. When the first stop rod 520 moves into the first cylinder 500, the annular flange 560 is in contact with the drive ring 540, and the annular flange 560 pushes the drive ring 540 and triggers the trigger button 570.

[0062] The controller monitors the duration of the trigger button 570 being triggered during the movement of the first stopper 520 into the first cylinder 500. When the duration is less than the time threshold, the controller controls the driver 400 to stop and sends a prompt to the administrator.

[0063] The time threshold can be flexibly set according to actual conditions. Under normal circumstances, after the first piston 510 pushes air into the second cylinder 700, the first piston 510 begins to reset. In the second cylinder 700, the second piston 710 pushes air to continue entering the filter cartridge 800 to continue purifying the air. When the first piston 510 has completely reset, the second piston 710 has also returned to the end of the second cylinder 700 near the one-way valve 600. At this time, the first cylinder 500 is full of air, and the air in the second cylinder 700 has been emptied, making it easy for the second cylinder 700 to receive the next wave of air.

[0064] As usage time increases, the gaps between the deodorizing material 820 and the dust-removing material in the filter cartridge 800 may become partially blocked, affecting the purification speed of the filter cartridge 800. At this time, when the first piston 510 resets, the movement speed of the second piston 710 will slow down. After the first piston 510 resets, the second piston 710 may not have returned to the end of the second cylinder 700 near the one-way valve 600, meaning the drive ring 540 has not fully reset. This results in the annular flange 560 not immediately engaging with the drive ring 540 when the first piston 510 pushes air into the second cylinder 700 again. Consequently, the duration of the trigger button 570 being triggered during the movement of the first stopper rod 520 into the first cylinder 500 will be shorter.

[0065] When the duration is less than the time threshold, it means that the reset speed of the second piston 710 is too slow, which means that the air permeability of the deodorizing material 820 / dust removal material in the filter cartridge 800 has become very poor, and it is very likely that the required purification effect or purification speed can no longer be achieved. At this time, the controller controls the driver 400 to stop and sends a prompt to the manager, so that the manager can replace the deodorizing material 820 / dust removal material in the filter cartridge 800 in time.

[0066] In summary, the ventilated pigsty 1000 provided in this embodiment of the invention can ensure continuous air exchange while preventing odor leakage and continuously improving the air quality inside the pigsty.

[0067] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
