Description

Technical Field

[0001] The present invention relates to the technical field of air purification, and in particular to an intelligent air purification device and a poultry house air purification system. Background Art

[0002] An indoor air purifier is a device specially designed to improve indoor air quality, remove pollutants from the air, and keep the indoor air fresh. It can remove pollutants from the air, such as particulate matter, harmful gases, and microorganisms. Some air purifiers have humidification or dehumidification functions, which help to regulate indoor humidity and make the air more comfortable. Among them, wet dust removal technology is usually used for air purification in some larger venues. The purified air is discharged to the outside or returned to the room as needed.

[0003] Wet air purifier can effectively remove liquid or solid particles with a diameter of 0.1 to 20 μm from the airflow, and at the same time, it can also remove some gaseous pollutants. It has the advantages of simple structure, small footprint, convenient operation and maintenance, and high purification efficiency. It can handle high-temperature and high-humidity airflow. It consists of an axial flow fan, a water pump, a nozzle, an ultraviolet lamp, a negative ion generator, and a shell. The schematic diagram of its purification principle is shown below. Fig.21 As shown, a is a spray kettle, b is a pump body, c is a spray head, d is an ultraviolet sterilization lamp, e is an exhaust device, and f is a negative ion generating device. After the air enters, it is "washed → killed → adjusted" and then discharged to be purified. "Washing" means washing the air with water. Pollutants such as ammonia and hydrogen sulfide in livestock and poultry houses are easily soluble in water and can be absorbed by water after contact with water. Dust and other particulate matter are captured under the action of inertial collision and other factors. The water pump draws water from the sump and sprays it out from the nozzle to form a spray layer in the shell. The axial flow fan is placed on the upper part of the shell and an air inlet is provided at the lower part. Under the action of the axial flow fan, negative pressure is formed in the shell. Air is sucked in through the air inlet and fully contacts with the water in the spray layer to absorb or adsorb pollutants such as ammonia, hydrogen sulfide, and dust in the air. "Killing" means using ultraviolet lamps for disinfection to kill microorganisms in the air in order to prevent microbial contamination in the air. "Adjustment" means setting a negative ion generator at the nozzle to further treat the air, increase the concentration of negative water ions, and adjust the air quality.

[0004] The disadvantage of wet dust removal is that it consumes a lot of water. In order to overcome the disadvantage of wet dust removal and reduce water consumption, the existing technology designs a filter structure to filter and treat the used water, so as to recycle water resources. However, the method of filtering the used water with a filter structure will cause impurities such as filter residues to be blocked on the filter screen. In the long run, it will lead to a decrease in the water permeability of the filter screen, thereby reducing the filtering effect. In the prior art, a Chinese patent for a water curtain type wet dust removal device (Announcement No. CN221557899U) is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: "Through the dust removal and dirt removal mechanism, during use, the water pump is driven so that the water pump pipe draws out water, and the water falls into the inside of the top cover through the transmission of the water transmission pipe and is transmitted to the inside of the dust removal cabinet. The water baffle can prevent water from flowing to the outside. The guide plate 1 and the guide plate 2 can guide the water flow to form a water curtain. When the gas carrying dust reaches the inside of the dust removal cabinet, the water will fall to the back of the wastewater tank with the dust, and the sewage pump is driven so that the sewage pump pipe draws out the sewage, and the sewage delivery pipe transports the sewage to the inside of the treatment box. Under the action of the filter plate, the sewage is filtered and waits for the next use. When the filter plate is blocked, the motor is driven so that the transmission shaft of the motor drives the threaded rod to rotate, so that the scraper is repeatedly driven to clean the surface of the filter plate, so that the dust removal device can perform water curtain type wet dust removal and recycle and clean the sewage after dust removal for reuse." However, this solution still has the following problems:

[0005] Although the water has been filtered, it still contains other non-particle contamination after long-term repeated use, so it is necessary to change the water regularly, which increases the workload in the later stage;

[0006] The cleaning process requires the use of a sewage pump to pump out the sewage for filtration, and when the filter plate is blocked, the motor drives the scraper to scrape the filter plate. The overall cost of implementation is high, and multiple drives are required to work together. When the scraper is scraping the filter plate, friction will occur between the particles and the filter plate, thereby causing wear on the filter plate.

[0007] It is often difficult to remove tiny particles attached to the filter plate, and they may get stuck in the filter holes during the scraping process, causing blockage and affecting the recycling effect. Some particles will be crushed by the scraper and the filter plate and fall down through the filter holes, thereby polluting the water quality and seriously damaging the water pump. Summary of the invention

[0008] The object of the present invention is to provide an intelligent air purification device and a poultry house air purification system to solve the problem of poor treatment effect and high treatment cost in the process of water reuse during wet dust removal in the prior art.

[0009] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0010] An intelligent air purification device comprises: a spray tower, water is contained in the spray tower, a fan is installed on the top of the spray tower, a negative ion generator is fixedly installed in the spray tower, an ultraviolet lamp is fixedly installed in the middle of the spray tower, an input pipe is arranged on one side of the spray tower, a spray pipe is fixedly connected to the outside of the spray tower, a plurality of shunt pipes are arranged on the spray pipe, the shunt pipes all extend to the inside of the spray tower and are fixedly installed with nozzles, a water pump is fixedly installed on one side of the spray tower, the input end of the water pump is connected to the lower end of the spray tower, and the water pump is fixedly installed on the upper side of the spray tower. The output end of the water pump is connected to the spray pipe; it also includes: a water collection tank, which is connected to the spray tower through a conduction pipe and is used to collect rainwater and provide it to the spray tower; an air duct, which is fixedly connected to the end of the input pipe away from the spray tower, and is provided with a plurality of air inlets, and the air inlets are used to inhale the air to be purified; a sieve bucket, which is fixedly connected between the inner walls of the spray tower, and the sieve bucket is set as a funnel-shaped filter structure, which is used to separate the water in the spray tower from the solid and the liquid, and the bottom of the spray tower is provided with a water outlet, and the lower end of the sieve bucket is fixedly connected to the water outlet;

[0011] By adopting the above technical solution, due to the design of the screen bucket structure, the particles will automatically gather in the central position after being filtered, especially during the spraying process, when the impact of rainwater produces a slight shake, and the screen bucket is in the shape of a funnel, which will drive the particles to move, so they will not be evenly spread out, reducing the impact on subsequent filtration, so that the filter structure can be used for a longer time without cleaning.

[0012] The further improvement of the technical solution of the present invention is that: a self-cleaning component is arranged at the bottom of the spray tower, and is used to control the spray tower to discharge water and impurities through buoyancy when the water level in the spray tower rises; a signal acquisition module is installed on the outer wall of the air duct, and is used to detect the concentration of particulate matter in the air; a controller is used to process the concentration signal collected by the signal acquisition module, and control the operation of the water pump and the fan when the particulate matter in the air reaches a set concentration; the self-cleaning component includes a rotating rod rotatably connected between the inner walls of the spray tower, a swing rod is fixedly connected to the outer side of the rotating rod, a float is fixedly connected to the end of the swing rod away from the rotating rod, one end of the rotating rod extends to the outside of the spray tower, a drain valve is fixedly connected to the bottom of the spray tower, the drain valve is connected to the spray tower through a pipeline, the bottom of the drain valve is fixedly connected to a water outlet pipe, a first valve core is rotatably connected between the inner walls of the drain valve, a valve hole is opened on the first valve core, and one end of the central axis of the first valve core extends to the outside of the drain valve and is connected to the rotating rod through a belt and pulley transmission.

[0013] By adopting the above technical solution, when it rains, the water collection tank begins to collect rainwater, and the rainwater enters the spray tower through the conduction pipe. With the continuous inflow of rainwater, the liquid level inside the spray tower will rise, so that the float begins to rise, and the rotating rod is driven to rotate through the rocker arm. Furthermore, the first valve core is driven to rotate through the pulley and belt transmission. The valve hole on the first valve core is a straight hole, and initially, the valve hole and the spray tower are staggered. As the first valve core rotates to nearly 90°, the valve hole can drain water at different speeds. When the valve hole is in a vertical state when the first valve core rotates, the bottom of the spray tower is connected to the external environment to the greatest extent, so that water and particulate impurities can be discharged together.

[0014] A further improvement of the technical solution of the present invention is that: a cross bar is fixedly connected between the inner walls of the spray tower, a sleeve rod is rotatably connected to the bottom of the cross bar, a filter is fixedly connected to the bottom of the sleeve rod, a pressure rod is slidably connected between the inner walls of the sleeve rod, a first spring is fixedly connected between the filter and the pressure rod, a spiral transmission groove is opened on the inner wall of the sleeve rod, a transmission buckle is fixedly connected to the outer side of the pressure rod, the transmission buckle is slidably connected to the transmission groove, a cam is fixedly connected to the central position of the outer side of the rotating rod, and the outer side of the cam is in contact with the top of the pressure rod; and a blade is fixedly connected to the outer side of the sleeve rod.

[0015] By adopting the above technical solution, a rotatable blade is provided, and it can be linked with the rotating rod. During the process of rising water level inside the spray tower, the cam will be driven to rotate along with the rotation of the rotating rod, thereby squeezing the pressure rod and compressing the first spring. The pressure rod moves downward to drive the transmission buckle to squeeze the transmission groove downward, so that the sleeve rod rotates and drives the blades to rotate, so that the water in the spray tower rotates to generate a vortex, so as to help the particles adhering to the screen bucket and the particles accumulated at the lower end of the screen bucket become loose, so that they can be easily discharged when the first valve hole is opened. When the cam is reset and rotated, the pressure rod rebounds under the elastic force of the first spring and drives the sleeve rod to rotate.

[0016] A further improvement of the technical solution of the present invention is that: a water injection valve is fixedly connected to the bottom of the spray tower, a filling pipe is arranged on one side of the water injection valve, the water injection valve is connected to the spray tower through a pipeline, and the pipeline used to connect the water injection valve and the spray tower and the filling pipe are perpendicular to each other, a second valve core is rotatably connected between the inner walls of the water injection valve, an L-shaped hole is provided on the second valve core, the second valve core is fixedly connected to the central axis of the first valve core, and one end of the filling pipe away from the water injection valve is connected to the external water supply pipeline; a mounting plate is fixedly connected to the bottom of the spray tower, two limit plates are fixedly connected to one side of the mounting plate, a stop block is fixedly connected to the outer side of the central axis of the first valve core, and the stop block and the limit plate cooperate to limit the rotation range of the first valve core.

[0017] The above technical solution is adopted, and the float is still used for transmission as the basis of the water injection signal, thereby reducing the cost required for control. Specifically, the float itself has a certain weight. When the water level drops, the float moves downward and drives the rotating rod to rotate through the rocker arm, thereby rotating the second valve core (the first valve core will also rotate during the process, but will not rotate to the valve hole conduction state) until the L-shaped hole can conduct the external water supply pipe and the spray tower. The external water supply pipe is a tap water pipe. When the L-shaped hole is connected, the water supply to the spray tower is completed, and the water level rises after the water supply, which will block the second valve core again, thereby keeping the water level in the spray tower in a dynamic balance as a whole, and no manual regulation and processing are required.

[0018] A further improvement of the technical solution of the present invention is that the conduction pipe is an inverted U-shaped pipe, a nozzle is fixedly installed at one end of the conduction pipe located in the spray tower, and the height of the nozzle is lower than the height of one end of the conduction pipe located in the water collection tank.

[0019] By adopting the above technical solution, by setting the conduction pipe into a U shape, according to the siphon principle, when rainwater begins to pass through the conduction pipe, the conduction pipe will continuously draw water from the water collecting tank until the water level in the water collecting tank is higher than the water collecting tank or the water level in the water collecting tank is lower than the end of the conduction pipe (located at one end of the water collecting tank), and the rainwater enters the spray tower and is sprayed out from the nozzle. When the water level in the spray tower is shallow, the sprayed water directly acts on the screen bucket, thereby flushing the screen bucket.

[0020] A further improvement of the technical solution of the present invention is that a filter cover is fixedly connected to the top of the water collection tank, the top of the filter cover is an arc-shaped protrusion, and the filter cover is used to filter rainwater.

[0021] By adopting the above technical solution, a filter cover is set up to filter rainwater before it falls into a water collection tank. The filter cover structure is in the shape of a round bottom pot. During the filtering process, impurities can automatically flow toward the periphery along the top arc surface, thereby avoiding blockage caused by long-term filtration and requiring no manual maintenance.

[0022] A further improvement of the technical solution of the present invention is that the diameters of the valve hole and the water outlet pipe are both larger than the diameter of the conduction pipe.

[0023] By adopting the above technical solution, when the valve hole is in a completely vertical state, the drainage speed of the spray tower is greater than the speed of water entering the spray tower from the water collecting tank, thereby avoiding the water level in the spray tower from being too high; secondly, the design can enable the water level in the spray tower to always maintain a dynamic balance close to the vertical state of the valve hole, so the float is also in a state of repeated up and down swinging, further, the blades are constantly reversed, causing the water inside the spray tower to churn, so as to fully clean the screen bucket.

[0024] The present invention also provides a poultry house air purification system, comprising: a feeding shed, wherein a plurality of feeding cages are installed inside the feeding shed, a fixed mesh plate is provided at the central position of the bottom of the feeding cage, a mesh support structure composed of a plurality of modular mesh plates is provided at both sides of the fixed mesh plate at the bottom of the feeding cage, a support rod is fixedly connected between the inner walls of the feeding cage near the bottom, and the modular mesh plates are rotatably connected to the outer sides of the support rods; a cross plate is fixedly connected to the bottom of the support rods, two piston cylinders are symmetrically fixedly connected to one side of the cross plate, a piston plate is slidably connected between the inner walls of the piston cylinders, a bottom cover is detachably connected to the bottom of the piston cylinder, and the bottom of the bottom cover slides The cam is movably connected with a slide rod, the top of which extends to the interior of the piston cylinder and is fixedly connected to the piston plate, the bottom of the slide rod is fixedly connected to a linkage frame, the bottom of the modular mesh plate is in contact with the top of the linkage frame, and a second spring is sleeved on the outside of the slide rod and located inside the piston cylinder; the top of the piston cylinder is fixedly connected to an exhaust pipe, the side wall of the piston cylinder is fixedly connected to an exhaust pipe, the exhaust pipe is communicated with the piston cylinder, and both the exhaust pipe and the exhaust pipe are provided with a one-way valve, both sides of the breeding cage are fixedly connected to a transfer pipe, one end of the transfer pipe is communicated with the air duct, and the exhaust pipe is communicated with the transfer pipe; a limiting ring is fixedly connected between the inner walls of the piston cylinder.

[0025] By adopting the above technical solution, by setting the bottom part of the breeding cage as a modular mesh plate, when the poultry steps on one end, it will tilt up, so that the modular mesh plate on the pressed side will press the linkage frame downward, so that the second spring is compressed and drives the slide rod to move downward, and drives the piston plate to move downward. During this process, the one-way valve in the air extraction pipe is connected, and the one-way valve in the exhaust pipe is blocked, so that the piston cylinder extracts air through the air extraction pipe (air enters from the air inlet hole), and when the poultry leaves the pressed end or walks to the other end (one end of the modular mesh plate will be pressed down), the linkage frame, the slide rod and the piston plate on this side are reset under the reset of the second spring, and when the piston plate moves upward, the one-way valve in the air extraction pipe is blocked, and the one-way valve in the exhaust pipe is connected, so that the air will be discharged to the transfer pipe; since the air extraction operation occurs at the place where the poultry walks, it is possible to extract air at the location where the poultry is, and no power drive is required, saving implementation costs.

[0026] A further improvement of the technical solution of the present invention is that vertical plates are symmetrically fixedly connected on both sides of the bottom of the modular mesh panel, the vertical plates are installed at the outermost tangent position of the modular mesh panel, the vertical plates on adjacent modular mesh panels are in contact with each other, and two anti-pinch rings are sleeved between the sides of the modular mesh panel close to the fixed mesh panel, and connecting rods are fixedly connected between the anti-pinch rings.

[0027] By adopting the above technical solution, vertical plates are arranged at both ends of the bottom of the modular mesh panels. When adjacent modular mesh panels move relative to each other to form an angle, the vertical plates fill the gaps so that there is no gap that can be stepped on, thereby avoiding the possibility of birds being pinched. Anti-pinch rings and connecting rods are arranged between the modular mesh panels and the fixed mesh panels, which can produce a slope during the movement of the modular mesh panels, reducing the number of standing positions where birds can be pinched, thereby reducing the risk of pinching.

[0028] A further improvement of the technical solution of the present invention is that: one end of the transfer pipe away from the air duct is fixedly connected to the air inlet, the top of the inner wall of the air inlet is hinged with a wind blocking plate, the inner wall of the air inlet is fixedly connected with a baffle, and the baffle is in contact with one side of the wind blocking plate.

[0029] By adopting the above technical solution, when the piston cylinder is not pumping out air, the air duct is evacuated when the fan is working normally, and the air enters the transfer pipe through the air inlet. During the process, the air blocking plate will be pushed open, thereby generating an air flow channel in the transfer pipe to the air duct. When the piston cylinder moves (its corresponding piston plate makes a piston movement), the exhausted air can flow along the air flow channel; when the piston cylinder moves but the fan is not working (at this time the concentration of particulate matter in the air is low and can be discharged directly), since there is no air flow channel in the transfer pipe and the air blocking plate is not opened, the air exhausted from the piston cylinder is discharged into the transfer pipe, pressed into the air duct, and discharged directly to the outside, and cannot be discharged back into the room through the air blocking plate, thereby preventing particulate matter from accumulating in the poultry activity area.

[0030] A further improvement of the technical solution of the present invention is that a conical baffle cover is fixedly connected to the top of the exhaust pipe, a plurality of ventilation holes are opened on the outside of the exhaust pipe, the bottom area of ​​the conical baffle cover is larger than the bottom area of ​​the piston cylinder, there is a gap between the conical baffle cover and the piston cylinder, and a plurality of air inlet holes are opened on the outside of the exhaust pipe.

[0031] By adopting the above technical solution, a conical shield is arranged on the top of the exhaust pipe, which can block and guide the falling impurities and prevent the impurities from being sucked into the piston cylinder.

[0032] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0033] 1. The present invention collects rainwater by setting a water collection tank, and injects rainwater into the spray tower for flushing and guiding the release of used water. During the rain, the continuous inflow of rainwater will increase the liquid level inside the spray tower, so that the float begins to rise, and the swing rod drives the rotating rod to rotate, driving the first valve core to rotate, and the bottom of the spray tower is connected to the external environment, so that water and particulate impurities can be discharged together, thereby realizing automatic water replacement.

[0034] 2. The present invention filters the water after spraying by setting a funnel-shaped filter. The particles will automatically gather in the central position after being filtered, especially when the impact of rainwater produces a slight shake during the spraying process, and the screen bucket is in the shape of a funnel, which will drive the particles to move, so they will not be evenly spread out, reducing the impact on subsequent filtration, so that the filter structure can be used for a longer time without cleaning, so as to maintain a good filtering effect when it does not rain for a long time.

[0035] 3. The present invention provides rotatable blades that can be linked with the rotating rod. During the rising process of the water level inside the spray tower, the rotation of the rotating rod will drive the cam to rotate, thereby squeezing the pressure rod and compressing the first spring. The pressure rod moves downward to drive the transmission buckle to squeeze the transmission groove downward, so that the sleeve rod rotates and drives the blades to rotate, so that the water in the spray tower rotates to generate a vortex, thereby helping the particles adhering to the screen bucket and the particles accumulated at the lower end of the screen bucket to become loose, so that they can be easily discharged when the first valve hole is connected to avoid blockage.

[0036] 4. The present invention sets a water injection valve controlled by the water level. When the water level drops, the float moves downward and drives the rotating rod to rotate through the rocker arm, thereby rotating the second valve core until the L-shaped hole can connect the external water supply pipe and the spray tower. The external water supply pipe is a tap water pipe. When the L-shaped hole is connected, the water supply to the spray tower is completed. After the water supply, the rising water level will block the second valve core again, thereby keeping the water level in the spray tower in a dynamic balance as a whole, and no manual adjustment and processing are required.

[0037] 5. The present invention sets the conduction pipe to be U-shaped. According to the siphon principle, when rainwater starts to pass through the conduction pipe, the conduction pipe will continuously draw water from the water collecting tank until the water level in the water collecting tank is higher than the water collecting tank or lower than the end of the conduction pipe. The rainwater enters the spray tower and is sprayed out from the nozzle. When the water level in the spray tower is shallow, the sprayed water directly acts on the sieve bucket, so that the sieve bucket can be flushed. The diameter of the valve hole is set to be larger than the diameter of the conduction pipe. When the valve hole is in a completely vertical state, the drainage speed of the spray tower is greater than the speed of entering the spray tower from the water collecting tank, thereby avoiding the water level in the spray tower from being too high. Secondly, the design can keep the water level in the spray tower in a dynamic balance close to the vertical state of the valve hole. Therefore, the float is also in a state of repeated up and down swinging. Further, the blades are continuously reversed, causing the water inside the spray tower to churn, so as to fully clean the sieve bucket.

[0038] 6. The present invention sets the bottom part of the breeding cage as a modular mesh plate, which can accompany the birds to move to different positions. Through transmission, the air inside the breeding cage can be evacuated and discharged into the air duct. Since the air extraction operation occurs at the place where the birds walk, it can be evacuated at the position where the birds are located, and no power drive is required, saving implementation costs.

DETAILED DESCRIPTION

[0062] The present invention is further described in detail below in conjunction with embodiments:

[0065] Specifically, the fan 101 is controlled to work so that air is sucked from the air duct 103 and discharged through the spray tower 1, and then discharged to the outside after purification. The purification is specifically as follows: the water pump 105 is controlled to work, water is pumped from the lower end of the spray tower 1, and water mist is sprayed into the spray tower 1 through the spray pipe 19 and the nozzle 106. The above air is mixed with the water mist when passing through the spray tower 1, so that the particulate matter in the air settles downward, thereby achieving air purification.

[0067] Specifically, due to the design of the sieve bucket 12 structure, the particles will automatically gather in the central position after being filtered, especially when the impact of rainwater produces slight shaking during the spraying process, and the sieve bucket 12 is in the shape of a funnel, which will drive the particles to move, so they will not be evenly spread out, reducing the impact on subsequent filtration, so that the filter structure can be used for a longer time without cleaning.

[0068] The self-cleaning component is arranged at the bottom of the spray tower 1, and is used to control the spray tower 1 to discharge water and impurities through buoyancy when the water level in the spray tower 1 rises; the signal acquisition module is installed on the outer wall of the air duct 103, and is used to detect the concentration of particulate matter in the air; the controller is used to process the concentration signal collected by the signal acquisition module, and control the water pump 105 and the fan 101 to work when the particulate matter in the air reaches a set concentration; the self-cleaning component includes a rotating rod 201 rotatably connected between the inner walls of the spray tower 1, and the outer side of the rotating rod 201 is fixedly connected to a swing rod 202, and the swing rod 20 A floating ball 203 is fixedly connected to one end away from the rotating rod 201, one end of the rotating rod 201 extends to the outside of the spray tower 1, a drain valve 204 is fixedly connected to the bottom of the spray tower 1, the drain valve 204 is communicated with the spray tower 1 through a pipeline, a water outlet pipe 205 is fixedly connected to the bottom of the drain valve 204, a first valve core 206 is rotatably connected between the inner walls of the drain valve 204, a valve hole 207 is opened on the first valve core 206, one end of the central axis of the first valve core 206 extends to the outside of the drain valve 204 and is connected to the rotating rod 201 through a belt and a pulley transmission.

[0069] In this embodiment, when it rains, the water collection tank 11 starts to collect rainwater, and the rainwater enters the spray tower 1 through the conduction pipe 13. With the continuous inflow of rainwater, the liquid level inside the spray tower 1 will rise, so that the float 203 begins to rise, and drives the rotating rod 201 to rotate through the rocker arm 202. Further, the first valve core 206 is driven to rotate through the pulley and belt transmission. The valve hole 207 on the first valve core 206 is a straight hole, and initially, the valve hole 207 is staggered from the spray tower 1. As the first valve core 206 rotates to nearly 90°, the valve hole 207 can drain water at different speeds. When the valve hole 207 is in a vertical state when the first valve core 206 rotates, the bottom of the spray tower 1 is connected to the external environment to the greatest extent, so that water and particulate impurities can be discharged together.

[0070] Embodiment 2:

[0071] like Figure 2 , Figure 4 and Fig.18As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, a cross bar 309 is fixedly connected between the inner walls of the spray tower 1, a sleeve rod 301 is rotatably connected to the bottom of the cross bar 309, a filter 303 is fixedly connected to the bottom of the sleeve rod 301, a pressure rod 304 is slidably connected between the inner walls of the sleeve rod 301, a first spring 305 is fixedly connected between the filter 303 and the pressure rod 304, a spiral transmission groove 307 is opened on the inner wall of the sleeve rod 301, a transmission buckle 306 is fixedly connected to the outer side of the pressure rod 304, the transmission buckle 306 is slidably connected to the transmission groove 307, a cam 308 is fixedly connected to the central position of the outer side of the rotating rod 201, and the outer side of the cam 308 is in contact with the top of the pressure rod 304; a blade 302 is fixedly connected to the outer side of the sleeve rod 301.

[0072] Since the self-cleaning component relies on the accumulation of rainwater, it cannot be manually controlled, and usually requires a certain time interval to operate. During this time period, particulate impurities will accumulate on the screen bucket 12 and it is difficult for them to flow out with the water flow. In particular, impurities at the lower end of the screen bucket 12 will cause the lower end of the screen bucket 12 to be blocked, so that when the first valve core 206 is turned on, there is a situation where the impurities cannot be discharged or the discharge is slow;

[0073] In this embodiment, by providing a rotatable blade 302 that can be linked with the rotating rod 201, during the process of the water level rising inside the spray tower 1, the rotation of the rotating rod 201 will drive the cam 308 to rotate, thereby squeezing the pressure rod 304 and compressing the first spring 305. The pressure rod 304 moves downward to drive the transmission buckle 306 to squeeze the transmission groove 307 downward, so that the sleeve rod 301 rotates, and drives the blade 302 to rotate, so that the water in the spray tower 1 rotates to generate a vortex, so as to help the particles adhered to the screen bucket 12 and the particles accumulated at the lower end of the screen bucket 12 become loose, so that they can be easily discharged when the first valve hole 207 is opened. When the cam 308 is reset and rotated, the pressure rod 304 rebounds under the elastic force of the first spring 305 and drives the sleeve rod 301 to rotate.

[0074] Embodiment three:

[0075] like Figure 3 and Figure 6As shown, on the basis of the second embodiment, the present invention provides a technical solution: preferably, a water injection valve 401 is fixedly connected to the bottom of the spray tower 1, a filling pipe 402 is arranged on one side of the water injection valve 401, the water injection valve 401 is connected to the spray tower 1 through a pipeline, and the pipeline used to connect the water injection valve 401 and the spray tower 1 is perpendicular to the filling pipe 402, a second valve core 403 is rotatably connected between the inner walls of the water injection valve 401, an L-shaped hole 404 is provided on the second valve core 403, the second valve core 403 is fixedly connected to the central axis of the first valve core 206, and one end of the filling pipe 402 away from the water injection valve 401 is connected to an external water supply pipeline; a mounting plate 17 is fixedly connected to the bottom of the spray tower 1, two limit plates 15 are fixedly connected to one side of the mounting plate 17, a stopper 16 is fixedly connected to the outer side of the central axis of the first valve core 206, and the stopper 16 cooperates with the limit plate 15 to limit the rotation range of the first valve core 206.

[0076] During the air purification process, water mist is blown out with the airflow and evaporates. If it does not rain for a long time, the water level will drop, and external water injection is required;

[0077] In this embodiment, the float 203 is still used for transmission as the basis of the water injection signal to reduce the cost required for control. Specifically, the float 203 itself has a certain weight. When the water level drops, the float 203 moves downward and drives the rotating rod 201 to rotate through the rocker 202, thereby rotating the second valve core 403 (the first valve core 206 will also rotate during the process, but will not rotate to the valve hole 207 The conductive state), until the L-shaped hole 404 can conduct the external water supply pipeline and the spray tower 1. The external water supply pipeline is a tap water pipe. When the L-shaped hole 404 is conductive, the water supply to the spray tower 1 is completed, and the water level rises after the water replenishment, which will block the second valve core 403 again, so that the water level in the spray tower 1 is generally in a dynamic balance, and no manual regulation and processing are required.

[0078] Specifically, Figure 6 It is a schematic diagram of the cross-sectional structure of the sewage valve 204 and the water injection valve 401 of the present invention in three states, wherein the left side shows when the water level is normal, the water injection valve 401 and the sewage valve 204 are both not connected; the upper right shows when the water level rises to the highest, the water injection valve 401 is blocked and the sewage valve 204 is connected; the lower right shows when the water level is relatively low, the water injection valve 401 is connected and the sewage valve 204 is blocked.

[0079] like Figure 2 , Figure 3 and Fig.18 As shown, preferably, the conduction pipe 13 is an inverted U-shaped pipe, and a nozzle 14 is fixedly installed at one end of the conduction pipe 13 located in the spray tower 1, and the height of the nozzle 14 is lower than the height of one end of the conduction pipe 13 located in the water collecting tank 11.

[0080] The spray tower 1 is connected to the water collecting tank 11 through the transmission pipe 13. If the transmission pipe 13 is only set as a straight pipe, the water transmission process will be slow and no large "water waves" will be caused, so the flushing of the screen bucket 12 cannot be completed.

[0081] In this embodiment, by setting the conduction pipe 13 to a U shape, according to the siphon principle, when rainwater begins to pass through the conduction pipe 13, the conduction pipe 13 will continuously extract water from the water collecting tank 11 until the water level in the water collecting tank 11 is higher than the water collecting tank 11 or the water level in the water collecting tank 11 is lower than the end of the conduction pipe 13 (located at one end of the water collecting tank 11), and the rainwater enters the spray tower 1 and is sprayed out from the nozzle 14. When the water level in the spray tower 1 is shallow, the sprayed water directly acts on the screen bucket 12, thereby flushing the screen bucket 12.

[0082] like Figure 1 , Figure 2 and Figure 3 As shown, preferably, a filter cover 18 is fixedly connected to the top of the water collecting tank 11, and the top of the filter cover 18 is an arc-shaped protrusion, and the filter cover 18 is used to filter rainwater.

[0083] Since the device relies on rainwater to flush and replace used water, it is inevitable that some impurities will be adsorbed in the rainwater. If it is used directly, it is easy to further increase the impurity content in the water.

[0084] In this embodiment, by setting up a filter cover 18, rainwater can be filtered and then fall into the water collection tank 11. The filter cover 18 has a round bottom pot shape. During the filtering process, impurities can automatically flow along the top arc surface to the periphery, thereby avoiding blockage caused by long-term filtration and requiring no manual maintenance.

[0085] Embodiment 4:

[0086] On the basis of the third embodiment, the present invention provides a technical solution: preferably, the diameters of the valve hole 207 and the water outlet pipe 205 are both larger than the diameter of the conduction pipe 13 .

[0087] In this embodiment, when the valve hole 207 is in a completely vertical state, the drainage speed of the spray tower 1 is greater than the speed of water entering the spray tower 1 from the water collecting tank 11, thereby avoiding the water level in the spray tower 1 from being too high; secondly, this design can enable the water level in the spray tower 1 to always be maintained in a dynamic balance close to the vertical state of the valve hole 207, so the float 203 is also in a state of repeated up and down swinging, further, the blade 302 is continuously reversed, causing the water inside the spray tower 1 to churn, so as to fully clean the screen bucket 12.

[0088] like Figure 7 , Fig. 9 and Fig.10As shown, the present invention also provides a poultry house air purification system, comprising: a breeding shed 21, wherein a plurality of breeding cages 5 are installed inside the breeding shed 21, a fixed mesh plate 501 is located at the central position of the bottom of the breeding cage 5, and a mesh support structure composed of a plurality of modular mesh plates 503 is located on both sides of the fixed mesh plate 501 at the bottom of the breeding cage 5, a support rod 502 is fixedly connected between the inner walls of the breeding cage 5 near the bottom, and the modular mesh plate 503 is rotatably connected to the outer side of the support rod 502; a cross plate 504 is fixedly connected to the bottom of the support rod 502, and two piston cylinders 505 are symmetrically fixedly connected to one side of the cross plate 504, a piston plate 508 is slidably connected between the inner walls of the piston cylinder 505, a bottom cover is detachably connected to the bottom of the piston cylinder 505, and a slide rod 507 is slidably connected to the bottom of the bottom cover, and the slide rod 507 is detachably connected to the bottom of the bottom cover. The top of 07 extends to the interior of the piston cylinder 505 and is fixedly connected to the piston plate 508, the bottom of the slide rod 507 is fixedly connected to the linkage frame 506, the bottom of the modular mesh plate 503 is in contact with the top of the linkage frame 506, and the second spring 509 is sleeved on the outside of the slide rod 507 and located inside the piston cylinder 505; the top of the piston cylinder 505 is fixedly connected to the exhaust pipe 511, the side wall of the piston cylinder 505 is fixedly connected to the exhaust pipe 510, the exhaust pipe 510 is communicated with the piston cylinder 505, and the exhaust pipe 510 and the exhaust pipe 511 are both provided with a one-way valve, both sides of the breeding cage 5 are fixedly connected to the transfer pipe 513, one end of the transfer pipe 513 is communicated with the air duct 103, and the exhaust pipe 510 is communicated with the transfer pipe 513; the inner walls of the piston cylinder 505 are fixedly connected with a limiting ring.

[0089] The concentration of particulate matter in the poultry breeding environment will directly affect the health of the poultry. When the intelligent air purification device is used in the poultry house air purification system, the poultry house environment is more complex, including the large breeding shed 21, and it is difficult to achieve air extraction to cover the entire site; the breeding cages 5 are scattered, and the air extraction cannot be targeted at the location of the poultry; there are many dead corners in the poultry house environment, which cannot be covered during air extraction, so the effect is limited when air purification is performed on large-scale poultry houses. The main reason is that: although more branch pipelines can be added to the air duct 103 to target each corner of the breeding shed 21, the air intake of the air purification device relies on the fan 101 to exhaust the air duct 103, and a spraying operation is required during the process. If the power of the fan 101 is set too large, it will inevitably cause the air to pass quickly, which will cause the particulate matter in the air to be discharged before it is completely settled, and even the sprayed water mist will be discharged together. In addition, this method will also increase the implementation cost, so it is not realistic to only set up a high-power fan 101;

[0090] In this embodiment, by setting the bottom part of the breeding cage 5 as a modular mesh plate 503, when the poultry steps on one end, it will tilt up, so that the modular mesh plate 503 on the pressed side will press the linkage frame 506 downward, so that the second spring 509 is compressed and drives the slide bar 507 to move downward, and drives the piston plate 508 to move downward. During this process, the one-way valve in the air extraction pipe 511 is turned on, and the one-way valve in the exhaust pipe 510 is blocked, so that the piston cylinder 505 is evacuated through the air extraction pipe 511 (air enters from the air inlet 512), and When the poultry leaves one end that is pressed down or walks to the other end (one end of the modular mesh plate 503 will be pressed down), the second spring 509 will reset the linkage frame 506, the slide rod 507 and the piston plate 508 on that side. When the piston plate 508 moves upward, the one-way valve in the air extraction pipe 511 is blocked and the one-way valve in the exhaust pipe 510 is connected, thereby discharging air to the transfer pipe 513. Since the air extraction operation occurs at the place where the poultry walks, air can be extracted at the location of the poultry without the need for power drive, thus saving implementation costs.

[0091] A limiting ring is arranged inside the piston cylinder 505 to limit the movement of the piston plate 508 , thereby limiting the tilting angle of the modular mesh plate 503 .

[0092] like Fig.13 , Fig.14 and Fig. 20 As shown, preferably, vertical plates 25 are symmetrically fixedly connected on both sides of the bottom of the modular mesh panel 503, and the vertical plates 25 are installed at the outermost tangent position of the modular mesh panel 503. The vertical plates 25 on adjacent modular mesh panels 503 are in contact with each other, and two anti-pinch rings 23 are sleeved between the sides of the modular mesh panel 503 close to the fixed mesh panel 501, and connecting rods 24 are fixedly connected between the anti-pinch rings 23.

[0093] Since the modular mesh panels 503 are movable, and gaps are generated at the contact positions between adjacent modular mesh panels 503 and the fixed mesh panels 501 during movement, birds may be easily injured;

[0094] In this embodiment, vertical plates 25 are provided at both ends of the bottom of the modular mesh panels 503. When adjacent modular mesh panels 503 move relative to each other to form an angle, the vertical plates 25 fill in the gaps so that there is no gap that can be stepped on, thereby avoiding the possibility of birds being pinched. An anti-pinch ring 23 and a connecting rod 24 are provided between the modular mesh panels 503 and the fixed mesh panels 501, which can form a slope during the movement of the modular mesh panels 503, thereby reducing the number of standing positions where birds can be pinched, thereby reducing the risk of being pinched.

[0095] like Fig.14 and Fig.17As shown, preferably, one end of the transfer pipe 513 away from the air duct 103 is fixedly connected to the air inlet 601, the top of the inner wall of the air inlet 601 is hinged with a wind blocking plate 602, the inner wall of the air inlet 601 is fixedly connected with a baffle 603, and the baffle 603 is in contact with one side of the wind blocking plate 602.

[0096] In this embodiment, when the piston cylinder 505 does not pump out air, the air duct 103 is evacuated when the fan 101 is working normally, and the air enters the transfer pipe 513 through the air inlet 601. During the process, the air blocking plate 602 is pushed open, so that an air flow channel flowing to the air duct 103 is generated in the transfer pipe 513. When the piston cylinder 505 moves (its corresponding piston plate 508 makes a piston movement), the exhausted air can flow along the air flow channel; when the piston cylinder 505 moves but the fan 101 is not working (at this time, the concentration of particulate matter in the air is low and can be discharged directly), since there is no air flow channel in the transfer pipe 513 and the air blocking plate 602 is not opened, the air exhausted from the piston cylinder 505 is discharged into the transfer pipe 513, pressed into the air duct 103, and discharged directly to the outside, and cannot be discharged back to the room through the air blocking plate 602, so as to prevent particulate matter from accumulating in the poultry activity area.

[0097] like Fig.15 , Fig.16 and Fig. 20 As shown, preferably, a conical baffle 514 is fixedly connected to the top of the exhaust pipe 511, a plurality of ventilation holes are opened on the outer side of the exhaust pipe 511, the bottom area of ​​the conical baffle 514 is larger than the bottom area of ​​the piston cylinder 505, there is a gap between the conical baffle 514 and the piston cylinder 505, and a plurality of air inlet holes 512 are opened on the outer side of the exhaust pipe 511.

[0098] Since the above-mentioned structure for exhausting air is arranged below the feeding cage 5, during the poultry feeding process, impurities such as feces or feathers may fall downwards and easily block the exhaust passage;

[0099] In this embodiment, a conical shield 514 is provided on the top of the exhaust pipe 511 to block and guide the falling impurities, thereby preventing the impurities from being sucked into the piston cylinder 505 .

[0100] The working principle of the intelligent air purification device and the poultry house air purification system is explained in detail below.

[0101] like Figure 1-Figure 21As shown, by controlling the operation of the fan 101, the air is sucked out of the air duct 103 and discharged through the spray tower 1, and then discharged to the outside after purification. A rain shelter is arranged above the spray tower 1, and the water collecting tank 11 is arranged in an open air environment. The purification is specifically as follows: controlling the operation of the water pump 105 to pump water from the lower end of the spray tower 1, and spraying water mist into the spray tower 1 through the spray pipe 19 and the nozzle 106. The above-mentioned air is mixed with the water mist when passing through the spray tower 1, so that the particulate matter in the air settles downward and falls on the sieve bucket 12, and the water penetrates downward through the sieve bucket 12, and the particulate matter is blocked in the sieve bucket 12.

[0102] Due to the design of the sieve bucket 12 structure, the particles will automatically gather in the central position after being filtered, especially when the impact of rainwater produces slight shaking during the spraying process, and the sieve bucket 12 is in the shape of a funnel, which will drive the particles to move, so they will not be evenly spread out, reducing the impact on subsequent filtration, so that the filter structure can be used for a longer time without cleaning.

[0103] The device is applicable to areas with abundant rainfall. When it rains, the water collecting tank 11 starts to collect rainwater. When the rainwater is higher than the top of the conductive pipe 13, the rainwater starts to flow into the spray tower 1 through the conductive pipe 13. Since the conductive pipe 13 is arranged as an inverted U-shaped structure, according to the siphon principle, when rainwater starts to pass through the conductive pipe 13, the conductive pipe 13 will continuously extract water from the water collecting tank 11 until the water level in the water collecting tank 11 is higher than the water collecting tank 11 or the water level in the water collecting tank 11 is lower than the end of the conductive pipe 13 (located at one end of the water collecting tank 11). After the rainwater enters the spray tower 1, it is sprayed out from the nozzle 14. When the water level in the spray tower 1 is shallow, the sprayed water directly acts on the screen bucket 12, thereby being able to flush the screen bucket 12.

[0104] As the rainwater continues to flow in, the liquid level inside the spray tower 1 will rise, so that the float 203 starts to rise, and the swing rod 202 drives the rotating rod 201 to rotate. Further, the first valve core 206 is driven to rotate through the pulley and the belt transmission. The valve hole 207 on the first valve core 206 is a straight hole, and initially, the valve hole 207 is staggered with the spray tower 1. As the first valve core 206 rotates to nearly 90 degrees, the valve hole 207 can drain water at different speeds. When the first valve core 206 rotates, the valve hole 207 is in a vertical state. In the closed state, the bottom of the spray tower 1 is connected to the external environment to the greatest extent (at this time, the block 16 is in contact with the limit plate 15 located above), and its drainage speed is controlled by the water level in the spray tower 1, that is, the higher the water level in the spray tower 1, the greater the drainage speed through the first valve core 206; along with the drainage of the valve hole 207, the particles gathered in the center of the screen bucket 12 will be discharged downward, thereby completing the self-cleaning of the particles. When the valve hole 207 is in a vertical state, the block 16 contacts one of the limit plates 15, and the first valve core 206 cannot continue to rotate.

[0105] In addition, during the rising process of the water level inside the spray tower 1, the rotation of the rotating rod 201 will drive the cam 308 to rotate, thereby squeezing the pressure rod 304 and compressing the first spring 305. The pressure rod 304 moves downward to drive the transmission buckle 306 to squeeze the transmission groove 307 downward, so that the sleeve rod 301 rotates, and drives the blade 302 to rotate, so that the water in the spray tower 1 rotates to generate a vortex, so as to help the particles adhering to the screen bucket 12 and the particles accumulated at the lower end of the screen bucket 12 become loose, so that they can be easily discharged when the first valve hole 207 is connected. When the cam 308 is reset and rotated, the pressure rod 304 rebounds under the elastic force of the first spring 305, and drives the sleeve rod 301 to rotate.

[0106] Among them, the diameters of the valve hole 207 and the outlet pipe 205 are both larger than the diameter of the conduction pipe 13. Therefore, when the valve hole 207 is in a vertical state, its drainage speed is greater than the discharge speed of the water collecting tank 11 to the spray tower 1. Therefore, the water level in the spray tower 1 can always be maintained in a dynamic balance close to the valve hole 207 being in a vertical state. Therefore, the float 203 is also in a state of repeated up and down swinging. Further, the blade 302 is continuously reversed, causing the water inside the spray tower 1 to churn so as to fully clean the screen bucket 12. After the rain stops, the water level in the spray tower 1 will gradually drop due to drainage, causing the first valve core 206 to rotate until the valve hole 207 is offset from the spray tower 1, thereby stopping drainage.

[0107] During the rotation of the first valve core 206, the second valve core 403 will rotate synchronously, but the hole on the second valve core 403 is an L-shaped hole 404. In the initial state, the process of rotating to the first valve core 206 is not able to rotate to the point where the two ends of the L-shaped hole 404 correspond to the spray tower 1 and the external water supply pipe respectively, so water will not be injected. When it has not rained for a long time, external control of water injection is required. Specifically, the float 203 itself has a certain weight. When the water level drops, the float 203 moves downward and swings The rod 202 drives the rotating rod 201 to rotate, thereby rotating the second valve core 403 (the first valve core 206 will also rotate during the process, but will not rotate to the valve hole 207 The conductive state), until the L-shaped hole 404 can conduct the external water supply pipeline and the spray tower 1. The external water supply pipeline is a tap water pipe. When the L-shaped hole 404 is connected, the water replenishment of the spray tower 1 is completed, and the water level rises after the water replenishment, which will block the second valve core 403 again, so that the water level in the spray tower 1 is in a dynamic balance as a whole, and no manual regulation and processing are required.

[0108] In addition, in the poultry house air purification system proposed by the present invention, the bottom part of the breeding cage 5 is provided with a modular mesh plate 503, and when the poultry steps on one end, the modular mesh plate 503 will be tilted, so that the modular mesh plate 503 on the pressed side will press the linkage frame 506 downward, so that the second spring 509 is compressed and the slide bar 507 is driven to move downward, and the piston plate 508 is driven to move downward. During this process, the one-way valve in the air extraction pipe 511 is turned on, and the one-way valve in the exhaust pipe 510 is blocked, so that the piston cylinder 505 is exhausted through the air extraction pipe 511 (air is discharged from the air inlet hole 512). When the poultry leaves the pressed end or walks to the other end (one end of the modular mesh plate 503 is pressed down), the side linkage frame 506, the slide bar 507 and the piston plate 508 are reset under the reset of the second spring 509. When the piston plate 508 moves upward, the one-way valve in the air extraction pipe 511 is blocked, and the one-way valve in the exhaust pipe 510 is connected, so that the air is discharged to the transfer pipe 513. Since the air extraction operation occurs at the place where the poultry walks, it is possible to extract air at the location of the poultry, and no power drive is required, which saves the implementation cost.

[0109] The transfer pipe 513 is connected to the air duct 103. When the piston cylinder 505 does not pump out air, the air duct 103 is pumped out when the fan 101 is working normally. The air enters the transfer pipe 513 through the air inlet 601. During the process, the air blocking plate 602 is pushed open, thereby generating an air flow channel in the transfer pipe 513 that flows to the air duct 103. When the piston cylinder 505 moves (its corresponding piston plate 508 performs piston movement), the exhausted air can flow along the air flow channel; when the piston cylinder 505 moves but the fan 101 is not working (at this time, the concentration of particulate matter in the air is low and can be discharged directly), since there is no air flow channel in the transfer pipe 513 and the air blocking plate 602 is not opened, the air exhausted from the piston cylinder 505 is discharged into the transfer pipe 513, pressed into the air duct 103, and discharged directly to the outside to prevent particulate matter from accumulating in the poultry activity area.

[0110] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
