Description

Technical Field

[0001] The present invention relates to the technical field of ventilation for livestock and poultry houses, and in particular to a dust removal and deodorization 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 received increasing attention. In order to remove dust in livestock and poultry houses by exhausting air and improve the odor problem, the existing deodorizing wall-free integrated deodorizing fan has gradually been widely used. This device mainly consists of a box, a fan, a demisting and water collection system, a water sprinkling system, a filtration system and a water pump. Its working principle is as follows:

[0003] After the fan is started, the gas in the box is extracted, and the water sprinkling system evenly sprinkles the deodorizing liquid onto the filter system. The deodorizing liquid that flows through the filter system then falls to the bottom of the box, and is then re-pumped into the water sprinkling system through a water pump to form a cycle. In this process, the gas to be treated enters from the bottom of the box, and comes into contact with the deodorizing liquid when passing through the filter system to achieve gas deodorization. The gas then passes through the demisting and water collection system to remove moisture, and is finally discharged from the upper side of the box.

[0004] However, the prior art has the following deficiencies:

[0005] Uneven air intake: Since the box adopts a horizontal air intake design, the part of the filter system close to the air inlet will directly contact the gas, while the part of the filter system far from the air inlet cannot fully contact the gas due to uneven airflow distribution, resulting in uneven air intake effect of the entire filter system;

[0006] Excessive contact problem of the filtration system: The part of the filtration system close to the air inlet is in contact with the gas to be treated for a long time, which is prone to the accumulation of dust, particulate matter or other pollutants on the surface, thereby forming blockage, resulting in uneven airflow and reducing the ventilation efficiency of the entire system. Summary of the Invention

[0007] In order to solve the problems mentioned in the above background technology, the present invention provides a dust removal and deodorization ventilation device for livestock and poultry houses.

[0008] The technical solution of the present invention is: a dust removal and deodorization ventilation device for livestock and poultry houses, comprising a cabinet body, a mounting frame fixedly connected to the upper side of the cabinet body, an exhaust fan arranged in the mounting frame, a fixed shell fixedly connected to the cabinet body, a bottom plate for supporting the fixed shell arranged in the cabinet body, an upper porous shell and a lower porous shell rotatably connected in the fixed shell, uniformly distributed guide plates are fixedly connected in the upper porous shell and the lower porous shell, a water pump is arranged in the cabinet body below the fixed shell, a liquid spraying part located above the upper porous shell is fixedly connected to the upper side of the fixed shell, the liquid spraying part is connected to the water pump, and a driving component for driving the upper porous shell and the lower porous shell to rotate and making the two rotate in opposite directions is arranged in the cabinet body.

[0009] Preferably, a fixing ring located between the upper porous shell and the lower porous shell is fixed in the fixing shell, and evenly distributed oblique baffles are fixed to the fixing ring.

[0010] Preferably, the driving assembly includes evenly distributed connecting frames, which are all fixed in the cabinet body, and are used to lift the base plate. The opposite sides of the evenly distributed connecting frames are commonly fixed with a protective shell, and a driving motor is arranged in the protective shell. The driving shaft of the driving motor passes through the protective shell and the lower porous shell and is fixed to the lower porous shell. A gear reversing box is installed between the evenly distributed oblique baffles, and the lower side of the gear reversing box is connected to the driving shaft of the driving motor. The upper porous shell is fixed with a transmission shaft that is transmission-connected to the gear reversing box.

[0011] Preferably, the lower side of the upper porous shell is fixedly connected to and communicated with evenly distributed air ducts, and the air ducts are in a shape of a ﹚.

[0012] Preferably, a plurality of water inlets are provided at the position where the air guide tube is fixed to the upper porous shell, and the lower side surfaces of the water inlets and the lower side surface inside the upper porous shell are located at the same horizontal plane.

[0013] Preferably, a plurality of liquid outlet holes are provided at the lower portion of the air guide tube, and the air guide tube is provided with an overflow hole located above the liquid outlet holes.

[0014] Preferably, the upper side of the lower porous shell is fixedly connected to and communicated with a uniformly distributed first air guide shell, the first air guide shell is fixedly connected to and communicated with a second air guide shell, and the diameters of the two ends of the second air guide shell are different.

[0015] Preferably, a baffle is fixedly connected to a side of the second air guide housing away from the first air guide housing, and serrations are provided on the lower side of the baffle.

[0016] Preferably, the lower porous shell is provided with evenly distributed liquid guide holes, and the lower porous shell is provided with evenly distributed guide members, and the guide members are used to guide part of the liquid in the liquid guide holes to the guide plate in the lower porous shell.

[0017] Preferably, the center line of the air guide tube does not pass through the center axis of the upper porous shell, the side of the air guide tube that is not fixed to the upper porous shell is opposite to the rotation direction of the upper porous shell, the center line of the second air guide shell does not pass through the center axis of the lower porous shell, and the side of the second air guide shell close to the baffle is opposite to the rotation direction of the lower porous shell.

[0018] Compared with the prior art, the present invention has the following advantages: the present invention proposes a new layout, that is, the filtration system is divided into two parts, the upper porous shell and the lower porous shell, and the path of the gas to be treated flowing through the guide plate is changed by the relative rotation between the upper porous shell and the lower porous shell. This design enables the gas to be treated to pass through all the guide plates in the upper porous shell and the lower porous shell evenly, thereby reducing the risk of excessive contact in local areas while improving the gas treatment efficiency. At the same time, in the process of the gas flowing from the lower porous shell to the upper porous shell, the gas is re-watered in combination with the original water spraying system. Leaching further improves the efficiency of gas treatment. When the deodorizing liquid flows downward from the bottom of the upper porous shell, the liquid level at the bottom of the upper porous shell is controlled by the water inlet, so as to ensure the stability of the deodorizing liquid supply at the bottom of the upper porous shell. The guide member is in contact with the guide plate in the lower porous shell, so that the deodorizing liquid directly contacts the guide plate in the lower porous shell and flows downward along it. Compared with the existing method of freely falling water to contact the guide plate, the deodorizing liquid actively contacts the guide plate, further ensuring the water amount on the surface of the guide plate and improving the adsorption effect on dust or other impurities.

DETAILED DESCRIPTION

[0032] First of all, it should be noted that in the various described embodiments, identical components are provided with identical reference numerals or identical component names, wherein the disclosure contained throughout the entire description can be transferred to the same components having the same reference numerals or identical component names. Positional designations selected in the description, such as top, bottom, side, etc., also refer to the directly described and illustrated figures and are transferred to the new position in the event of a change in position.

[0033] In order to solve the problems of uneven air intake and excessive contact of the filtration system in the existing deodorization wall-free integrated deodorization fan, the present invention adopts the method of changing the layout of the filtration system and dividing the filtration system into two parts, and divides the filtration system into an upper porous shell 5 and a lower porous shell 6. The relative rotation of the upper porous shell 5 and the lower porous shell 6 changes the path of the gas flowing through the guide plate 7, so that the gas to be treated can pass through all the guide plates 7 in the upper porous shell 5 and the lower porous shell 6, thereby improving the treatment efficiency of the gas to be treated and reducing the wear of local areas.

[0034] Example 1:

[0035] This embodiment discloses a dust removal and deodorization ventilation device for livestock and poultry houses, which is used to remove dust and odors in the livestock and poultry houses and maintain ventilation in the livestock and poultry houses.

[0036] See also Figures 1-6 , including a cabinet 1, an air inlet is provided on the front side of the cabinet 1, a mounting frame 2 is fixedly connected to the upper side of the cabinet 1, an exhaust fan 3 is provided in the mounting frame 2, a filter is fixedly connected to the upper side of the mounting frame 2, a fixed shell 4 is fixedly connected to the cabinet 1, a bottom plate 41 for supporting the fixed shell 4 is provided in the cabinet 1, an upper porous shell 5 and a lower porous shell 6 are rotatably connected in the fixed shell 4, a plurality of dewatering plates are fixed to the cabinet 1 (the dewatering plates are existing dewatering mist collection systems), and the plurality of dewatering plates are located between the exhaust fan 3 and the fixed shell 4, and evenly distributed guide plates 7 are fixedly connected to the upper porous shell 5 and the lower porous shell 6. The vertical cross-section of the guide plate 7 is wavy. A water pump 8 is provided below the fixed shell 4. The liquid inlet of the water pump 8 is fixedly connected and connected to a tee. The lower side of the tee on the front side of the water pump 8 is fixedly connected and connected to a liquid extraction pipe for extracting the liquid at the bottom of the cabinet 1. Before this, a filter can be installed between the liquid extraction pipe and the tee to keep the water pump 8 clean when extracting the liquid at the bottom of the cabinet 1. The upper side of the fixed shell 4 is fixedly connected to a liquid spraying member 9 (the liquid spraying member 9 is an existing water sprinkling system) located above the upper porous shell 5. The liquid spraying member 9 is connected to the liquid outlet of the water pump 8 through a liquid pipe. A driving assembly 12 is provided in the cabinet 1 for driving the upper porous shell 5 and the lower porous shell 6 to rotate and making the two rotate in opposite directions.

[0037] See also Figure 2-Figure 6 , a fixing ring 10 is fixedly connected in the fixing shell 4 and is located between the upper porous shell 5 and the lower porous shell 6, and the fixing ring 10 is fixedly connected with evenly distributed oblique baffles 11, and the driving assembly 12 includes evenly distributed connecting frames 121, and the evenly distributed connecting frames 121 are all fixedly connected to the lower part of the cabinet 1, and the evenly distributed connecting frames 121 are used to lift the lower side of the bottom plate 41, and the opposite sides of the evenly distributed connecting frames 121 are fixedly connected with a protective shell 122, and a driving motor 123 is arranged in the protective shell 122, and the driving motor 1 The drive shaft of 23 passes through the protective shell 122 and the lower porous shell 6 and is fixedly connected to the lower porous shell 6. A gear reversing box 124 is installed between the evenly distributed oblique baffles 11. The lower side of the gear reversing box 124 is connected to the drive shaft of the drive motor 123. The upper porous shell 5 is fixedly connected to a transmission shaft that is transmission-connected to the gear reversing box 124. Through 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.

[0038] The working principle is: when it is necessary to remove dust, deodorize and ventilate the gas in the livestock and poultry house, the staff connects the outlet pipe of the livestock and poultry house to the air inlet on the front side of the cabinet 1, and then the staff connects the external liquid inlet pipe to the three-way pipe of the water pump 8, thereby completing the preparation work for gas treatment in the livestock and poultry house.

[0039] After completing the preparations for gas treatment in the livestock and poultry house, 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 cabinet 1 in a negative pressure state. Then 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 spraying part 9 through the liquid pipe on the upper side of the water pump 8. The spraying part 9 sends the deodorizing liquid to the guide plate 7 in the upper porous shell 5. As the deodorizing liquid flows, the deodorizing liquid falls onto the guide plate 7 in the lower porous shell 6. (As the deodorizing liquid falls downward from the guide plate 7 in the lower porous shell 6, a water curtain is formed in the lower part of the cabinet 1. All subsequent descriptions of the water curtain refer to this part), and finally falls to the bottom of the cabinet 1. At that time, the deodorizing liquid at the bottom of the cabinet 1 can be extracted by the water pump 8 (the flow path of the deodorizing liquid at the bottom of the cabinet 1 is: liquid extraction pipe → filter element → T-piece → water pump 8 → liquid pipe → liquid spray element 9) to achieve the effect of recycling the deodorizing liquid. The above is the detailed process of the deodorizing liquid flowing in the cabinet 1.

[0040] While the deodorizing liquid is flowing in the cabinet 1, the staff starts the drive motor 123 through the remote control terminal, and the drive shaft of the drive motor 123 drives the lower porous shell 6 to rotate counterclockwise (counterclockwise when viewed from top to bottom), and then the drive shaft of the drive motor 123 transmits power to the gear reversing box 124, and the gear reversing box 124 drives the upper porous shell 5 to rotate clockwise (clockwise when viewed from top to bottom) through the transmission shaft.

[0041] When the upper porous shell 5 and the lower porous shell 6 rotate, under the action of the negative pressure state in the cabinet 1, the gas to be treated enters the cabinet 1 from the air inlet on the front side, passes through the water curtain at the lower part of the cabinet 1 and comes into contact with the gas to remove large particles of dust in the gas, and the gas is deodorized by the deodorizing liquid.

[0042] The gas treated by the water curtain at the lower part inside the cabinet body 1 gradually flows upward from the lower part of the guiding plate 7 inside the lower porous shell 6 until it flows out from the upper part inside the lower porous shell 6. During this process, since the guiding plate 7 inside the upper porous shell 5 will guide the deodorizing liquid downward, therefore, a flushing chamber will be created 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 guiding plate 7 inside the upper porous shell 5. The gas in this flushing chamber is blocked by the uniformly 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, so as to enhance the efficiency of gas treatment. When the gas flows out from the guiding plate 7 inside the upper porous shell 5, it contacts the water droplet removing plate inside the cabinet body 1 to remove the moisture in the gas. This gas is finally discharged from the upper side of the installation frame 2.

[0043] When it is no longer necessary to treat the gas in the livestock and poultry house, the staff can close all the above-mentioned electrical components through the remote control terminal.

[0044] Embodiment 2:

[0045] This embodiment discloses a dust-removing and deodorizing ventilation device for livestock and poultry houses, which is improved on the basis of Embodiment 1.

[0046] Please refer to Figures 9-11 , the lower side of the upper porous shell 5 is fixedly connected with uniformly distributed air guide pipes 51. 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 with 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 inside the upper porous shell 5, which is used to guide the deodorizing liquid at the bottom inside 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 maintain 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 inside the lower porous shell 6. The horizontal ropes inside the guiding members 65 contact the upper side of the adjacent guiding plates 7.

[0047] 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 inside the upper porous shell 5 during the process of being sprayed out by the liquid spraying member 9 until it flows to the bottom inside the upper porous shell 5. The deodorizing liquid at the bottom inside 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, causing the liquid level of the deodorizing liquid at the bottom inside the upper porous shell 5 to gradually rise.

[0048] When the level of the deodorizing liquid at the bottom of the upper porous shell 5 rises to cover the upper side of all the air ducts 51, the deodorizing liquid enters all the air ducts 51. The stability of the deodorizing liquid supply is ensured by the above-mentioned method, and the deodorizing liquid in the air duct 51 is then sprayed out from all the liquid outlet holes 53 thereon (in order to prevent the liquid level in the air duct 51 from being too high and affecting the efficiency of the subsequent upward flow of gas, the deodorizing liquid will not flow out from the overflow hole 54 until the level of the deodorizing liquid in the air duct 51 rises to a threshold value).

[0049] The deodorizing liquid flowing out of all the liquid outlet holes 53 then 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 lower porous shell 6 guided by the liquid guide holes 64, part of the deodorizing liquid flows downward through the liquid guide holes 64, and the other part of the deodorizing liquid is actively guided to the guide plate 7 in the lower porous shell 6 through the guide member 65, so that the other part of the deodorizing liquid directly contacts the guide plate 7 in the lower porous shell 6 and flows downward along it. Compared with the existing method of contacting the guide plate 7 by free falling of water flow, the deodorizing liquid actively contacts the guide plate 7, further ensuring the water amount on the surface of the guide plate 7, and improving the adsorption effect on dust or other impurities. The deodorizing liquid falls to the bottom of the cabinet 1 under the guidance of the guide plate 7 in the lower porous shell 6.

[0050] The above are the effects brought about by the flow path and flow mode of the deodorizing liquid.

[0051] Example 3:

[0052] This embodiment discloses a dust removal and deodorization ventilation device for livestock and poultry houses, which is improved on the basis of Example 2.

[0053] See also Figure 5 、 Figure 6 and Figure 9 - Figure 12 The upper side of the lower porous shell 6 is fixedly connected to and communicated with a uniformly distributed first air guide shell 61, the first air guide shell 61 is fixedly connected to and communicated with a second air guide shell 62, the first air guide shell 61 is composed of a bent pipe and a truncated cone-shaped pipe, and the two are connected, the side of the truncated cone-shaped pipe with a larger diameter faces downward, so that Figure 12 For example, the diameter of the left end of the second air guide shell 62 is smaller than that of the right end, and 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. A baffle 63 is fixed to the side of the second air guide shell 62 away from the first air guide shell 61, and a serration is provided on the lower side of the baffle 63.

[0054] The above setting can be achieved. In the process of treating the gas in the livestock and poultry house, under the action of the exhaust fan 3 extracting the gas in the cabinet 1, the gas in the livestock and poultry house flows upward from the lower side of the cabinet 1, and the gas on the lower side of the cabinet 1 then flows upward through the guide plate 7 in the lower porous shell 6, and then the gas flows to the lower part of the first air guide shell 61. Under the action of the diameter of the lower part of the first air guide shell 61 gradually decreasing 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 to the serrations on the lower side of the baffle 63 under the action of gravity, and falls to the inner side of the upper part of the lower porous shell 6, and repeats the steps in Example 2.

[0055] The gas that hits the baffle 63 is then discharged from the lower part of the second air guide shell 62 away from the first air guide shell 61. The gas discharged from this way comes into contact with the deodorizing liquid sprayed from the liquid outlet 53, and the gas is deodorized. Then, under the action of the exhaust fan 3 extracting the gas in the cabinet 1, the gas passes through the deodorizing liquid sprayed from the liquid outlet 53 and enters the air guide pipe 51 from the front side thereof, and is then discharged from the rear side of the air guide pipe 51 (the flow direction of the gas in the air guide pipe 51 here can be referred to). Figure 10 ), until it enters the porous shell 5, the above operation is realized: the gas passes through the deodorizing liquid sprayed from the liquid outlet 53 and enters the air guide pipe 51, so that the gas is forced to contact with the deodorizing liquid, thereby improving the gas treatment efficiency.

[0056] Example 4:

[0057] This embodiment discloses a dust removal and deodorization ventilation device for livestock and poultry houses, which is improved on the basis of Example 3.

[0058] See also Figure 5-Figure 11 The center line of the air guide tube 51 does not pass through the central axis of the upper porous shell 5, the side of the air guide tube 51 that is not fixed to the upper porous shell 5 is opposite to the rotation direction of the upper porous shell 5, the center 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 is opposite to the rotation direction of the lower porous shell 6.

[0059] The above arrangement can achieve that, during the upward flow of gas in the cabinet 1, the lower porous shell 6 drives all the first air guide shells 61, the second air guide shells 62 and their accessories to rotate counterclockwise synchronously, and cooperates with the upper porous shell 5 to drive the air guide pipe 51 and its accessories to rotate clockwise. Compared with the vertical air guide, the time that the gas exists in the upper porous shell 5 and the lower porous shell 6 is extended, thereby increasing the contact time between the gas and the deodorizing liquid, thereby improving the gas treatment efficiency.
