DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes an air deodorization device and an exhaust deodorization method for broiler farming.

[0022] Embodiment 1: See also Figure 1 - Fig.11 An air deodorizing device comprises a device body 1, an air intake mechanism 2 and a collecting bin 4, the air intake mechanism 2 is fixedly mounted on the bottom of the device body 1, the collecting bin 4 is slidably mounted inside the air intake mechanism 2, air inlets 3 are fixedly mounted on both sides of the air intake mechanism 2, an air outlet 5 is fixedly mounted on the top of the device body 1, an exhaust fan 6 is fixedly mounted inside the air outlet 5, a filter chute 9 is opened on the inner side wall of the device body 1, and a transmission mechanism 8 is mounted on the inner side of the filter mechanism 7; The air inlets 3 on both sides of the air inlet mechanism 2 are connected to the air outlet 5 through the air inlet mechanism 2 and the device body 1; Two sets of filtering mechanisms 7 are installed inside the device body 1, and the adjacent sides of the two sets of filtering mechanisms 7 are connected to the transmission mechanism 8; When the exhaust fan 6 rotates, it can drive the air from the air inlet 3 through the air inlet mechanism 2 into the interior of the device body 1. While the exhaust fan 6 rotates, the transmission mechanism 8 drives the filter mechanism 7 to unfold. After the filter mechanism 7 is unfolded, it can filter the debris in the air entering the interior of the device body 1, and the filtered air is discharged from the air outlet 5. After the exhaust fan 6 stops rotating, the transmission mechanism 8 can drive the filter mechanism 7 to shrink. When the filter mechanism 7 shrinks, the debris adhered to the surface can fall off and fall into the interior of the collection bin 4.

[0023] When working, the device body 1 of the device is first installed in the reserved space on the roof of the chicken house. When the air inside the chicken house needs to be purified, the exhaust fan 6 is started, and the air in the chicken house is sucked into the air intake mechanism 2 from the air inlet 3 through the exhaust fan 6. When the exhaust fan 6 rotates, the filter mechanism 7 can be driven to expand through the transmission mechanism 8. After the filter mechanism 7 is expanded, the debris entering the air inside the device body 1 can be filtered. The filtered debris adheres to the surface of the filter mechanism 7 under the combined action of the exhaust fan suction and the surface adhesive. After working for a period of time, the exhaust fan 6 is turned off. After the exhaust fan 6 is turned off, the filter mechanism 7 can be driven to shrink through the transmission mechanism. When the filter mechanism 7 shrinks, the debris adhered to the surface can be automatically cleaned, and the cleaned debris falls downward into the air intake mechanism 2, and then enters and falls into the collection bin 4. By driving the filter mechanism 7 to expand when the exhaust fan 6 is started to filter the debris in the air, and after the exhaust fan 6 is turned off, the filter mechanism 7 can be driven to shrink to clean the debris adhered to the surface, thereby preventing the debris in the air of the chicken house from blocking the ventilation path for a long time.

[0024] Embodiment 2: See also Figure 2 - Figure 3 , which is different from the above-mentioned embodiment, is that the air intake mechanism 2 comprises an air intake body 21, which is mounted at the bottom of the device body 1, and the air intake ports 3 are fixedly connected to the two sides of the air intake body 21, a partition plate connecting block 22 is fixedly mounted inside the air intake body 21, a partition plate rotating shaft 23 is fixedly mounted at the bottom of the partition plate connecting block 22, an air intake partition plate 24 is rotatably mounted outside the partition plate rotating shaft 23, a mounting block 25 is fixedly mounted inside the air intake body 21, and a rotation limit block 26 is fixedly mounted on the inner wall of the air intake body 21; The collecting bin 4 is slidably mounted on the bottom end of the air inlet body 21 , and the collecting bin 4 can move along the direction of the mounting block 25 under the restriction of the mounting block 25 .

[0025] The other end of the air intake partition plate 24 is in contact with the inner wall of the air intake body 21, and the bottom of the air intake partition plate 24 is in contact with the rotation limit block 26; The collecting bin 4 is arranged below the air intake partition plate 24 .

[0026] Two air intake partition plates 24 are installed inside the air intake body 1. The two air intake partition plates 24 correspond to the two air intake ports 3 opened on both sides of the air intake body 21 respectively. The air intake partition plates 24 can rotate inside the air intake body 1 through the partition plate rotating shaft 23. When the air intake partition plates 24 rotate upward, they are in contact with the inner wall of the air intake body 21. When the air intake partition plates 24 rotate downward, the bottom of the air intake partition plates 24 contacts the rotating limit block.

[0027] When the exhaust fan 6 rotates, it first drives the air inlet partition plate 24 to rotate upward, and makes the air inlet partition plate 24 fit with the inner wall of the air inlet body 21. After the air inlet partition plate 24 fits with the inner wall of the air inlet body 21, the air inlet partition plate 24 can separate the upper and lower parts of the air inlet body 21. At this time, the air in the chicken house enters the air inlet body 21 from the air inlet port 3, and then enters the device body 1. After the exhaust fan 6 is turned off, the air inlet partition plate 24 rotates downward under the action of gravity until the lower surface of the air inlet partition plate 24 contacts the rotating limit block 26. At this time, the upper and lower parts of the air inlet body 21 are connected, and the filter The debris on the mechanism 7 enters the collection bin 4 after falling into the air intake body 21, and the conical structure inside the collection bin 4 can make the entered debris fall into the center of the collection bin 4. When the exhaust fan 6 is started to exhaust, it can drive the air intake partition plate 24 to rotate upward to separate the upper and lower parts of the air intake body 21, preventing the exhaust fan 6 from sucking the debris inside the collection bin 4 onto the filter mechanism 7. After the exhaust fan 6 is turned off, the air intake partition plate 24 automatically opens, causing the debris on the filter mechanism 7 to fall into the collection bin 4, thereby ensuring that the filtered debris is collected and preventing debris in the air from causing secondary pollution.

[0028] Embodiment three: See also Figure 4 - Figure 8 , which is different from the above-mentioned embodiment, is that the filtering mechanism 7 comprises a fixed filter plate 71, a filling filter plate 72 and a connecting filter plate 73, the fixed filter plate 71 is fixedly mounted inside the device body 1, the filling filter plate 72 and the connecting filter plate 73 are both slidably mounted inside the filter chute 9, a fixed plate block 74 is arranged on the top of the fixed filter plate 71, a filling plate block 75 is arranged on the top of the filling filter plate 72, a filling plate stopper 76 is arranged on the bottom of the filling filter plate 72, and a connecting plate stopper 77 is arranged on the bottom of the connecting filter plate 73; Two groups of filter mechanisms 7 are arranged inside the device body 1 , and each group of filter mechanisms 7 includes a fixed filter plate 71 , a connecting filter plate 73 and a plurality of filling filter plates 72 .

[0029] The fixed plate clamping block 74 and the filling plate limiting block 76 are connected to prevent the fixed filter plate 71 from being separated from the filling filter plate 72 close to the fixed filter plate 71; the filling plate clamping block 75 and the filling plate limiting block 76 are connected to prevent the two adjacent filling filter plates 72 from being separated; and the connecting plate limiting block 77 and the filling plate clamping block 75 are connected to prevent the connecting filter plate 73 from being separated from the filling filter plate. A plurality of filter chutes 9 are provided on the inner wall of the device body 1, and the fixed filter plate 71, the filling filter plate 72 and the connecting filter plate 73 are respectively slidably installed inside the separate filter chutes 9, and the installation positions of the fixed filter plate 71, the filling filter plates 72 and the connecting filter plates 73 are gradually raised.

[0030] When the exhaust fan 6 rotates, the transmission mechanism 8 can simultaneously drive the two connecting filter plates 73 to move toward the center of the device body 1. When the connecting filter plate 73 moves, the connecting plate limit block 77 can be fitted with the filling plate block 75 to drive the filling filter plate 72 connected thereto to move. The filling filter plates 72 are fitted with the filling plate block 75 and the filling plate limit block 76, so that when the connecting filter plate 73 moves, all the filling filter plates 72 can be gradually driven to unfold. After the two connecting filter plates 73 are in contact, the impurities in the air can be effectively filtered and the impurities in the air can be left on the surfaces of the connecting filter plate 73 and the filling filter plate 72. After the exhaust fan 6 is turned off, the transmission mechanism 8 can drive the connecting filter plate 73 and the filling filter plate 72 to move to both sides of the device body 1. When the connecting filter plate 73 and the filling filter plate 72 move, the filling plate block 75 and the fixed plate block 74 can scratch the debris adhered to the lower surface of the connecting filter plate 73 and the lower surface of the filling filter plate 72 to make them fall off. The debris in the air is filtered by the movable connecting filter plate 73 and the filling filter plate 72, and the debris adhered to the surface can be cleaned when the connecting filter plate 73 and the filling filter plate 72 shrink, thereby preventing the filter mechanism 7 from being blocked by sticky debris during long-term operation.

[0031] Embodiment 4: See also Fig. 9 - Fig.11 , which is different from the above-mentioned embodiment, is that the transmission mechanism 8 comprises a filter connecting plate 81 and a separation pressing plate 84, the outside of the filter connecting plate 81 is fixedly connected to the connection filter plate 73, the top of the filter connecting plate 81 is fixedly connected with a separation block 82, the outside of the filter connecting plate 81 is fixedly installed with a filter plate spring 83, the separation pressing plate 84 is slidably installed inside the device body 1, and the top of the separation pressing plate 84 is fixedly installed with a rising connecting plate 85; One end of the filter plate spring 83 is connected to the inner wall of the device body 1 , and the other end of the filter plate spring 83 is fixedly connected to the filter connecting plate 81 .

[0032] Both ends of the two connecting filter plates 73 are fixedly mounted with filter connecting plates 81. When the filter mechanism 7 is unfolded, the filter connecting plates 81 on the two connecting filter plates 73 are fitted together, and the separation blocks 82 on the top of the filter connecting plates 81 are bent to both sides. A protrusion is provided at the bottom of the separation lower pressing plate 84 , and the bottom of the separation lower pressing plate 84 is in contact with the top of the separation block 82 .

[0033] Separation lower pressing plates 84 are provided above the separation blocks 82 connected to both ends of the filter plate 73. The two separation lower pressing plates 84 are fixedly connected by a rising connecting plate 85. The outer portion of the separation lower pressing plate 84 is in contact with the inner side wall of the filter connecting plate 81. The rising connection plate 85 connects the tops of the two separated lower pressing plates 84 , and the rising connection plate 85 is provided with a protrusion below the air outlet 5 .

[0034] When the exhaust fan 6 rotates, the rising connecting plate 85 can be driven to move upward, and when the rising connecting plate 85 moves upward, the separation pressing plate 84 can be driven to move upward. After the separation pressing plate 84 moves upward, the filter plate spring 83 can drive the filter connecting plate 81 to move toward the center of the device body 1. When the filter connecting plate 81 moves toward the center of the device body 1, it can drive the filter mechanism 7 to expand. When the exhaust fan 6 stops rotating, the rising connecting plate 85 and the separation pressing plate 84 move downward. When the separation pressing plate 84 moves downward, it can be inserted from the center of the separation block 82 on the filter connecting plate 81, and drive the filter connecting plate 81 to move toward both sides of the device body 1 during the descending process of the separation pressing plate 84. When the filter connecting plate 81 moves, it can drive the filter mechanism 7 to shrink. When the exhaust fan 8 rotates, the transmission mechanism 8 can automatically drive the filter mechanism 7 to expand to filter the debris in the air in time, and when the exhaust fan 6 stops rotating, it can drive the filter mechanism 7 to shrink to clean the debris adhered to the surface, so that the debris on the filter mechanism 7 can be cleaned in time to prevent the debris on the filter mechanism 7 from being difficult to clean for too long.
