Description

Technical Field

[0001] The present invention relates to the technical field of ventilation for livestock and poultry houses, and particularly to a dust-removing and deodorizing ventilation device for livestock and poultry houses. Background Art

[0002] With the rapid development of the breeding industry, the air quality problem in livestock and poultry houses has attracted increasing attention. In order to remove dust in livestock and poultry houses by pumping air and improve the odor problem, the existing integrated deodorizing fan with a deodorizing wall has been gradually widely used. This device mainly consists of a box body, a fan, a demisting and water collection system, a water spraying system, a filtering system, and a water pump. Its working principle is as follows: After the fan starts, it extracts the gas in the box body. The water spraying system evenly sprays the deodorizing liquid onto the filtering system. The deodorizing liquid flowing through the filtering system then falls to the bottom of the box body, and is then re-extracted by the water pump and sent back to the water spraying system to form a cycle. During this process, the gas to be treated enters from the bottom of the box body, contacts the deodorizing liquid when passing through the filtering system to achieve gas deodorization, and then the gas passes through the demisting and water collection system to remove moisture, and finally is discharged from the upper side of the box body.

[0003] However, the existing technology has the following deficiencies: Uneven air intake: Due to the horizontal air intake design of the box body, the part of the filtering system close to the air inlet will directly contact the gas, while the part of the filtering system far from the air inlet cannot fully contact the gas due to uneven air flow distribution, resulting in uneven air intake effect of the entire filtering system; Over-contact problem of the filtering system: The part of the filtering system close to the air inlet is prone to accumulating dust, particulate matter, or other pollutants on its surface due to long-term contact with the gas to be treated, thus forming blockages, which leads to uneven air flow through and further reduces the ventilation efficiency of the entire system. Summary of the Invention

[0004] In order to solve the problems mentioned in the above background art, the present invention provides a dust-removing and deodorizing ventilation device for livestock and poultry houses.

[0005] The technical solution of the present invention is as follows: A dust-removing and deodorizing ventilation device for livestock and poultry houses, including a cabinet body, an installation frame is fixedly connected to the upper side of the cabinet body, an exhaust fan is arranged in the installation frame, a fixed shell is fixedly connected in the cabinet body, a bottom plate for supporting the fixed shell is arranged in the cabinet body, an upper porous shell and a lower porous shell are rotatably connected in the fixed shell, guide plates evenly distributed are fixedly connected in both the upper porous shell and the lower porous shell, a water pump is arranged below the fixed shell in the cabinet body, a liquid spraying member located above the upper porous shell is fixedly connected to the upper side of the fixed shell, the liquid spraying member is communicated with the water pump, and a driving component for driving the upper porous shell and the lower porous shell to rotate in opposite directions is arranged in the cabinet body.

[0006] Preferably, a fixing ring located between the upper porous shell and the lower porous shell is fixedly connected inside the fixing shell, and evenly distributed inclined baffle plates are fixedly connected to the fixing ring.

[0007] Preferably, the driving assembly includes evenly distributed connecting frames, and the evenly distributed connecting frames are fixedly connected inside the cabinet body. The evenly distributed connecting frames are used to lift the bottom plate. A protective shell is fixedly connected to the opposite sides of the evenly distributed connecting frames. A driving motor is arranged inside the protective shell. The driving shaft of the driving motor passes through the protective shell and the lower porous shell and is fixedly connected to the lower porous shell. A gear reversing box is installed between the evenly distributed inclined baffle plates. The lower side of the gear reversing box is connected to the driving shaft of the driving motor, and a transmission shaft in transmission connection with the gear reversing box is fixedly connected to the upper porous shell.

[0008] Preferably, evenly distributed air guide pipes are fixedly connected and communicated to the lower side of the upper porous shell, and the air guide pipes are in an L shape.

[0009] Preferably, a plurality of water inlets are arranged at the position where the air guide pipe is fixedly connected to the upper porous shell, and the lower side surfaces of the water inlets are on the same horizontal plane as the lower side surface inside the upper porous shell.

[0010] Preferably, a plurality of liquid outlet holes are arranged at the lower part of the air guide pipe, and an overflow hole is arranged on the air guide pipe above the liquid outlet holes.

[0011] Preferably, evenly distributed first air guide shells are fixedly connected and communicated to the upper side of the lower porous shell, the first air guide shells are fixedly connected and communicated to second air guide shells, and the two ends of the second air guide shells have different diameters.

[0012] Preferably, a baffle is fixedly connected to the side of the second air guide shell away from the first air guide shell, and sawteeth are arranged on the lower side of the baffle.

[0013] Preferably, evenly distributed liquid guide holes are arranged on the lower porous shell, and evenly distributed guiding members are arranged on the lower porous shell.

[0015] Compared with the prior art, the present invention has the following advantages: The present invention proposes a novel layout, that is, the filtration system is divided into an upper porous shell and a lower porous shell, and by the relative rotation between the upper porous shell and the lower porous shell, the path of the gas to be treated flowing through the guide plate is changed. This design enables the gas to be treated to evenly pass through all the guide plates in the upper porous shell and the lower porous shell, thereby reducing the risk of excessive contact in local areas while improving the gas treatment efficiency. At the same time, during the process of the gas flowing from the lower porous shell into the upper porous shell, the original water spraying system is combined to re-spray the gas, further improving the gas treatment efficiency. When the deodorizing liquid flows downward from the bottom inside the upper porous shell, the liquid level height at the bottom inside the upper porous shell is controlled through the water inlet to ensure the stability of the supply of the deodorizing liquid at the bottom inside the upper porous shell. By relying on the contact between the guiding member and the guide plate inside the lower porous shell, the deodorizing liquid directly contacts the guide plate inside the lower porous shell and flows downward along it. Compared with the existing method of the water flow freely falling to contact the guide plate, the deodorizing liquid actively contacts the guide plate, further ensuring the water quantity on the surface of the guide plate and improving the adsorption effect on dust or other impurities.

Detailed implementation mode

[0018] First of all, it should be pointed out that in different described implementation modes, the same components are provided with the same reference numerals or the same component names. Among them, the disclosed content included in the whole specification can be transferred to the same components with the same reference numerals or the same component names according to the meaning. The position descriptions selected in the specification, such as up, down, side, etc., also refer to the directly described and shown drawings and are transferred to the new positions according to the meaning when the positions change.

[0019] In order to solve the problems of uneven air intake and excessive contact of the existing integrated deodorization fan of the odor removal wall, the present invention adopts the method of changing the layout of the filtration system and dividing the filtration system into two parts. The filtration system is divided into two parts, the upper porous housing 5 and the lower porous housing 6. By the relative rotation of the upper porous housing 5 and the lower porous housing 6, the path of the gas flowing through the guide plate 7 is changed, so that the gas to be treated can pass through all the guide plates 7 in the upper porous housing 5 and the lower porous housing 6, improving the treatment efficiency of the gas to be treated while reducing the wear in the local area.

[0020] Embodiment 1: This embodiment discloses a dust removal and deodorization type ventilation device for livestock and poultry houses, which is used to remove dust and odor in the livestock and poultry houses and keep the ventilation in the livestock and poultry houses.

[0021] Please refer to Figures 1 - 6, including a cabinet body 1, an air inlet is arranged on the front side of the cabinet body 1, an installation frame 2 is fixedly connected to the upper side of the cabinet body 1, an exhaust fan 3 is arranged in the installation frame 2, a filter screen is fixedly connected to the upper side of the installation frame 2, a fixed shell 4 is fixedly connected in the cabinet body 1, a bottom plate 41 for supporting the fixed shell 4 is arranged in the cabinet body 1, an upper porous shell 5 and a lower porous shell 6 are rotatably connected in the fixed shell 4, the cabinet body 1 is fixedly connected with a plurality of dewatering plates (the dewatering plates are existing dewatering and water collection systems for water mist), and a plurality of dewatering plates are all located between the exhaust fan 3 and the fixed shell 4. Guide plates 7 are fixedly connected in both the upper porous shell 5 and the lower porous shell 6, and the cross-section of the guide plate 7 in the vertical direction is wavy. A water pump 8 is arranged below the fixed shell 4 in the cabinet body 1. The liquid inlet of the water pump 8 is fixedly connected and communicated with a three-way pipe. The lower side of the three-way pipe on the front side of the water pump 8 is fixedly connected and communicated with a liquid suction pipe for sucking the liquid at the bottom of the cabinet body 1. Before this, a filter element can be installed between the liquid suction pipe and the three-way pipe to keep the liquid sucked by the water pump 8 from the bottom of the cabinet body 1 clean. A liquid spraying member 9 (the liquid spraying member 9 is an existing water spraying system) located above the upper porous shell 5 is fixedly connected to the upper side of the fixed shell 4. The liquid spraying member 9 is communicated with the liquid outlet of the water pump 8 through a liquid conveying pipe. A driving assembly 12 is arranged in the cabinet body 1 for driving the upper porous shell 5 and the lower porous shell 6 to rotate in opposite directions.

[0022] Please refer to Figures 2 - 6 , a fixing ring 10 located between the upper porous shell 5 and the lower porous shell 6 is fixedly connected in the fixed shell 4. The fixing ring 10 is fixedly connected with uniformly distributed inclined baffle plates 11. The driving assembly 12 includes uniformly distributed connecting frames 121. The uniformly distributed connecting frames 121 are all fixedly connected to the lower part in the cabinet body 1. The uniformly distributed connecting frames 121 are used for lifting the lower side of the bottom plate 41. The opposite sides of the uniformly distributed connecting frames 121 are commonly fixedly connected with a protective shell 122. A driving motor 123 is arranged in the protective shell 122. The driving shaft of the driving motor 123 passes through the protective shell 122 and the lower porous shell 6 and is fixedly connected with the lower porous shell 6. A gear reversing box 124 is installed between the uniformly distributed inclined baffle plates 11. The lower side of the gear reversing box 124 is connected with the driving shaft of the driving motor 123. The upper porous shell 5 is fixedly connected with a transmission shaft that is in transmission connection with the gear reversing box 124. By the relative rotation between the upper porous shell 5 and the lower porous shell 6, the path of the gas to be treated flowing through the guide plate is changed, so that the gas flows through all the guide plates 7 in the upper porous shell 5 and the lower porous shell 6.

[0023] The working principle is as follows: When it is necessary to remove dust, deodorize and ventilate the gas in the livestock and poultry house, the staff connects the air outlet pipe of the livestock and poultry house to the air inlet on the front side of the cabinet body 1, and then the staff connects an external liquid inlet pipe to the three-way pipe of the water pump 8 to complete the preparation work for treating the gas in the livestock and poultry house.

[0024] After the preparatory work for gas treatment in the livestock and poultry house is completed, the staff starts the exhaust fan 3 through the remote control terminal. The exhaust fan 3 extracts the gas in the cabinet 1, making the inside of the cabinet 1 in a negative pressure state. Subsequently, the staff starts the water pump 8. The water pump 8 extracts the deodorizing liquid in the external liquid inlet pipe and sends the deodorizing liquid into the liquid spraying part 9 through the liquid passing pipe on the upper side of the water pump 8. The liquid spraying part 9 sends the deodorizing liquid onto the guide plate 7 in the upper porous shell 5. As the deodorizing liquid flows, the deodorizing liquid drops onto the guide plate 7 in the lower porous shell 6 (when the deodorizing liquid drops downward from the guide plate 7 in the lower porous shell 6, a water curtain is formed at the lower part of the inside of the cabinet 1, and all subsequent descriptions of the water curtain refer to this place), and finally falls to the bottom inside the cabinet 1. At this time, the deodorizing liquid at the bottom inside the cabinet 1 can be extracted by the water pump 8 (the flow path of the deodorizing liquid at the bottom inside the cabinet 1 is: liquid extraction pipe → filtering part → three-way pipe → water pump 8 → liquid passing pipe → liquid spraying part 9), so as to achieve the effect of recycling the deodorizing liquid. The above is the detailed process of the deodorizing liquid flowing in the cabinet 1.

[0025] During the process of the deodorizing liquid flowing in the cabinet 1, the staff starts the driving motor 123 through the remote control terminal. The driving shaft of the driving motor 123 drives the lower porous shell 6 to rotate counterclockwise (viewed from top to bottom, it rotates counterclockwise). Subsequently, the driving shaft of the driving motor 123 transmits the power to the gear reversing box 124, and the gear reversing box 124 drives the upper porous shell 5 to rotate clockwise (viewed from top to bottom, it rotates clockwise) through the transmission shaft.

[0026] After the upper porous shell 5 and the lower porous shell 6 rotate, under the action of the negative pressure state inside the cabinet 1, the gas to be treated enters the cabinet 1 from the air inlet on the front side of the cabinet 1, and passes through the contact between the water curtain at the lower part inside the cabinet 1 and the gas, removing large particle dust in the gas, and deodorizing the gas through the deodorizing liquid.

[0027] The gas treated by the water curtain at the lower part inside the cabinet 1 gradually flows upward from the lower part of the guide plate 7 in the lower porous shell 6 until it flows out from the upper part of the lower porous shell 6. During this process, since the guide plate 7 in the upper porous shell 5 will guide the deodorizing liquid downward, therefore, the deodorizing liquid will create a flushing chamber between the upper porous shell 5 and the lower porous shell 6. The gas is further flushed through this flushing chamber to further improve the gas treatment effect. The gas passing through this flushing chamber then flows upward along the guide plate 7 in the upper porous shell 5. The gas in this flushing chamber is blocked by the evenly distributed inclined baffle plates 11, extending the upward flow path of the gas and increasing the residence time of the gas in the flushing chamber, thereby enhancing the efficiency of gas treatment. When the gas flows out from the guide plate 7 in the upper porous shell 5, it contacts the water droplet removing plate inside the cabinet 1, thereby removing the moisture in the gas. This gas is finally discharged from the upper side of the mounting frame 2.

[0028] When it is no longer necessary to treat the gas in the livestock and poultry house, the staff can turn off all the above-mentioned electrical components through the remote control terminal.

[0029] Embodiment 2: This embodiment discloses a dust removal and deodorization type ventilation device for livestock and poultry houses, which is improved on the basis of Embodiment 1.

[0030] Please refer to Figures 9 - 11 , a plurality of uniformly distributed air guide pipes 51 are fixedly connected to the lower side of the upper porous shell 5. The air guide pipes 51 are L-shaped. A plurality of water inlets 52 are arranged at the position where the air guide pipes 51 are fixedly connected to the upper porous shell 5. The lower side surface of the water inlets 52 is on the same horizontal plane as the lower side surface in the upper porous shell 5, which is used to guide the deodorizing liquid at the bottom of the upper porous shell 5. A plurality of liquid outlet holes 53 are arranged at the lower part of the air guide pipes 51. The air guide pipes 51 are provided with overflow holes 54 above the liquid outlet holes 53. The overflow holes 54 are located at the middle position of the lower part of the corresponding air guide pipes 51. The overflow holes 54 are used to keep the liquid level in the corresponding air guide pipes 51 at a threshold value. The lower porous shell 6 is provided with uniformly distributed liquid guide holes 64. The lower porous shell 6 is provided with uniformly distributed guiding members 65. The guiding members 65 are composed of a plurality of Y-shaped ropes and horizontal ropes, and the Y-shaped ropes and the horizontal ropes are fixedly connected. The guiding members 65 are used to guide part of the liquid in the liquid guide holes 64 to the guiding plate 7 in the lower porous shell 6. The horizontal ropes in the guiding members 65 are in contact with the upper side of the adjacent guiding plates 7.

[0031] The working principle is as follows: When treating the gas in the livestock and poultry house, the deodorizing liquid flows along the guiding plate 7 in the upper porous shell 5 during the process of being sprayed out by the liquid spraying member 9 until it flows to the bottom of the upper porous shell 5. The deodorizing liquid at the bottom of the upper porous shell 5 then enters the corresponding air guide pipes 51 through all the water inlets 52. At this time, the amount of the deodorizing liquid sprayed out by the liquid spraying member 9 is greater than the amount discharged by all the water inlets 52, so that the liquid level of the deodorizing liquid at the bottom of the upper porous shell 5 gradually rises.

[0032] When the liquid level of the deodorizing liquid at the bottom of the upper porous shell 5 rises to cover the upper sides of all the air guide pipes 51, the deodorizing liquid enters all the air guide pipes 51. By the above method, the stability of the deodorizing liquid supply is ensured. The deodorizing liquid in the air guide pipes 51 is then sprayed out from all the liquid outlet holes 53 thereon (in order to prevent the liquid level in the air guide pipes 51 from being too high and affecting the upward flow efficiency of the subsequent gas, the deodorizing liquid will flow out from the overflow holes 54 only when the liquid level of the deodorizing liquid in the air guide pipes 51 rises to the threshold value).

[0033] The deodorizing liquid flowing out of all the liquid outlet holes 53 immediately flows to the inner side of the upper part of the lower porous shell 6. Under the action of the deodorizing liquid on the upper side of the porous shell 6 guided by the liquid guide hole 64, part of the deodorizing liquid flows downward through the liquid guide hole 64, and the other part of the deodorizing liquid is actively guided by the guide member 65 to the guide plate 7 inside the lower porous shell 6, so that the other part of the deodorizing liquid directly contacts the guide plate 7 inside the lower porous shell 6 and flows downward along it. Compared with the existing method of freely dropping water to contact the guide plate 7, the deodorizing liquid actively contacts the guide plate 7, further ensuring the water volume on the surface of the guide plate 7 and improving the adsorption effect on dust or other impurities. The deodorizing liquid drops to the bottom inside the cabinet 1 under the guidance of the guide plate 7 inside the lower porous shell 6.

[0034] The above are the effects brought by the flow path and flow mode of the deodorizing liquid.

[0035] Embodiment 3: This embodiment discloses a dust removal and deodorization type ventilation device for livestock and poultry houses, which is improved on the basis of Embodiment 2.

[0036] Please refer to Figure 5 、 Figure 6 and Figure 9 - Figure 12 On the upper side of the lower porous shell 6, there are fixedly connected and communicated with evenly distributed first air guide shells 61. The first air guide shells 61 are fixedly connected and communicated with second air guide shells 62. The first air guide shell 61 is composed of a bent pipe and a frustum-shaped pipe, and the two are communicated. The side with the larger diameter of the frustum-shaped pipe faces downward, so as to Figure 12 take... as an example. The diameter of the left end of the second air guide shell 62 is smaller than that of the right end, and it gradually increases from the left end to the right end, which is used to guide the moisture in the second air guide shell 62 and reduce the moisture content in the second air guide shell 62. On the side of the second air guide shell 62 away from the first air guide shell 61, there is a fixedly connected baffle 63, and sawteeth are arranged on the lower side of the baffle 63.

[0037] The above settings can achieve that during the process of treating the gas in the livestock and poultry house, under the action of the exhaust fan 3 extracting the gas inside the cabinet 1, the gas in the livestock and poultry house flows upward from the lower side inside the cabinet 1. The gas on the lower side inside the cabinet 1 then flows upward through the guide plate 7 inside the lower porous shell 6, and then the gas flows to the lower part inside the first air guide shell 61. Under the action of the gradually decreasing diameter of the lower part of the first air guide shell 61 from bottom to top, the gas is accelerated. The accelerated gas then enters the second air guide shell 62 from the upper side of the first air guide shell 61 and impacts the baffle 63, so that the moisture in the gas remains on the baffle 63, thereby reducing the water content in the gas. The moisture on the baffle 63 gathers towards the sawteeth on the lower side of the baffle 63 under the action of gravity and drops to the inner side of the upper part of the lower porous shell 6, and the steps in Embodiment 2 are repeated.

[0038] The gas of the impact baffle 63 is then discharged from the lower part of the second air guide shell 62 on the side far from the first air guide shell 61. The discharged gas contacts the deodorizing liquid ejected from the liquid outlet hole 53, and the gas is deodorized. Subsequently, under the action of the exhaust fan 3 extracting the gas in the cabinet 1, the gas passes through the deodorizing liquid ejected from the liquid outlet hole 53 and then enters the inside of the gas guide pipe 51 from the front side, and then is discharged from the rear side of the gas guide pipe 51 (the flow direction of the gas in the gas guide pipe 51 here can be referred to Figure 10 ), until it enters the porous shell 5. The above operation realizes that the gas passes through the deodorizing liquid ejected from the liquid outlet hole 53 and enters the gas guide pipe 51, so that the gas is forced to contact the deodorizing liquid, thereby improving the treatment efficiency of the gas.

[0039] Example 4: This embodiment discloses a dust removal and deodorization type ventilation device for livestock and poultry houses, which is improved on the basis of Example 3.

[0040] Please refer to Figures 5 - 11 , the central line of the gas guide pipe 51 does not pass through the central axis of the upper porous shell 5, the side of the gas guide pipe 51 not fixedly connected to the upper porous shell 5 faces away from the rotation direction of the upper porous shell 5, the central line of the second air guide shell 62 does not pass through the central axis of the lower porous shell 6, and the side of the second air guide shell 62 close to the baffle 63 faces away from the rotation direction of the lower porous shell 6.

[0041] The above settings can achieve that when the gas in the cabinet 1 flows upward, the lower porous shell 6 drives all the first air guide shells 61, the second air guide shells 62 and their accessory parts to rotate counterclockwise synchronously, and cooperates with the upper porous shell 5 to drive the gas guide pipe 51 and its accessory parts to rotate clockwise. Compared with the gas guide in the vertical direction, the time that the gas exists between the upper porous shell 5 and the lower porous shell 6 is prolonged, so as to increase the contact time between the gas and the deodorizing liquid, thereby improving the treatment efficiency of the gas.

[0042] The above has introduced the present application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
