Description

Technical Field

[0001] The present application relates to the technical field of rice, and specifically to an exhaust gas treatment device for the production of rice pesticides. Background Art

[0002] Rice, also known as paddy, rice grains, and rough rice, is a cereal crop of the genus Oryza in the family Poaceae. The rice stalk is erect, 0.5 - 1.5 meters tall, the leaf sheath is loose, and the two sides of the base extend downward to form the edge of the leaf sheath. The panicle is loose, the spikelet is oblong, flattened on both sides, contains 3 florets, the lemma of the bisexual floret often has fine hairs, with or without awns, there are 6 stamens, the caryopsis is about 5 mm long and about 2 mm wide. It is an important cereal widely planted in the tropical regions of Asia. The southern part of China is the main rice-producing area, and it is planted in all provinces in the north. It is mainly divided into two subspecies, indica rice and japonica rice.

[0003] A prior patent (publication number: CN216440280U) discloses an exhaust gas treatment device for the preparation of pesticides, belonging to the field of pesticide preparation. It includes a treatment tank. One side of the treatment tank is fixedly sleeved with an air inlet pipe, and the other side of the treatment tank is fixedly sleeved with a water inlet pipe. The inner side of the treatment tank is fixedly connected with a support platform. A spraying mechanism is arranged on the top of the support platform. A filter plate is fixedly connected inside the treatment tank. An exhaust mechanism is arranged on the top of the treatment tank. In this exhaust gas treatment device for pesticide preparation, by setting a water storage bucket, during the exhaust gas treatment process, it can effectively remove particulate matter and water-soluble harmful substances in the exhaust gas. And by setting the spraying mechanism and the filter plate, it can use the treatment liquid to re-treat the exhaust gas after water washing and adsorb odor molecules and moisture in the exhaust gas. This not only ensures the dryness of the filtered gas but also enhances the exhaust gas treatment effect.

[0004] During the use of the above document, the particles in the exhaust gas in the device are adsorbed by using water, and the exhaust gas is re-treated by the spraying mechanism. However, since the spraying device is in a fixed state, it will cause uneven spraying inside the device, and it is difficult to remove harmful substances in the exhaust gas only by water washing during use, and its practicability needs to be improved.

[0018] Furthermore, a plurality of stirring plates are fixedly connected to the outer surface of the rotating rod, and the plurality of stirring plates are distributed in a circular pattern.

[0019] Through the above solution, setting the stirring plates can buffer the tail gas and water source in the machine body, so that the water source can adsorb the impurities in the tail gas.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] Please refer to Figure 1 , Figure 2 and Figure 3 , in a tail gas treatment device for rice insecticide production in this embodiment, which includes a body 1. The inner top wall of the body 1 is rotatably connected to a rotating rod 2 through a sealing bearing. A cavity 3 is provided inside the rotating rod 2. A plurality of drainage cylinders 4 are arranged inside the body 1. A plurality of spraying holes 5 distributed in a circumferential manner are provided on the outer surface of each of the plurality of drainage cylinders 4. Grinding wheels 6 are fixedly connected to the upper ends of the plurality of drainage cylinders 4. A grinding ring 7 is installed on the inner wall of the body 1. Each of the plurality of grinding wheels 6 is in contact with the grinding ring 7. An intake pipe 8 is installed inside the body 1. The intake pipe 8 is in a spiral shape. A plurality of exhaust holes 9 are provided on the outer surface of the intake pipe 8. The plurality of exhaust holes 9 are arranged downward. The cooperation of the drainage cylinders 4 and the spraying holes 5 can spray a catalyst inside the body 1, and the cooperation of the grinding wheels 6 and the grinding ring 7 can make the drainage cylinders 4 rotate, so as to spray the catalyst inside the body 1 more evenly. At the same time, since the intake pipe 8 is in a spiral shape, the tail gas can be evenly contacted with the water inside the body 1, which is convenient for adsorbing impurities therein, thereby improving the treatment effect on the tail gas.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3, an activated carbon filter plate 10 is installed on the inner wall of the body 1. The rotating rod 2 does not contact the activated carbon filter plate 10. A sealing ring 11 is installed on the upper surface of the activated carbon filter plate 10. The sealing ring 11 contacts the rotating rod 2. Installing the sealing ring 11 can seal the connection between the rotating rod 2 and the activated carbon filter plate 10 to prevent the tail gas from leaking out between the two. The bottom ends of multiple drain tubes 4 are all rotatably connected to a communicating pipe 12 through a sealed bearing. The other ends of the multiple communicating pipes 12 are fixedly communicated with the cavity 3. Installing the communicating pipe 12 can transport the catalyst so that it enters the multiple drain tubes 4 and is sprayed out from the multiple water spray holes 5, thereby being able to purify the tail gas in the body 1. An inclined upward water inlet pipe 13 is installed at the upper end of the body 1, and a downward inclined drain pipe 14 is installed at the bottom end of the body 1. Valves 15 are installed on the outer surfaces of the water inlet pipe 13 and the drain pipe 14. Installing the valves 15 can seal the body 1 to prevent the tail gas in the body 1 from leaking.

[0033] Please refer to Figure 1 , Figure 2 and Figure 4 , a motor 16 is installed at the upper end of the body 1. The output end of the motor 16 is fixedly connected to the upper end of the rotating rod 2. An exhaust pipe 17 is fixedly communicated with the upper end of the body 1. The motor 16 can drive the rotating rod 2 to rotate, so that the rotating rod 2 can drive the multiple drain tubes 4 to swing, thereby being able to spray the catalyst in the body 1 more evenly., A communicating frame 18 is installed at the bottom end of the body 1. The bottom end of the rotating rod 2 is rotatably connected to the communicating frame 18 through a sealed bearing. The cavity 3 is communicated with the communicating frame 18. A liquid inlet pipe 19 is fixedly communicated with the bottom end of the communicating frame 18. The cooperation of installing the communicating frame 18 and the liquid inlet pipe 19 can pour the catalyst into the cavity 3, facilitating the transportation of the catalyst. Multiple stirring plates 20 are fixedly connected to the outer surface of the rotating rod 2. The multiple stirring plates 20 are distributed in a circular pattern. Setting the stirring plates 20 can relieve the tail gas and water source in the body 1, so that the water source can adsorb the impurities in the tail gas. Multiple support plates 21 are fixedly connected to the upper end of the rotating rod 2. Each of the multiple drain tubes 4 is rotatably connected to the support plate 21 close to it. Installing the support plate 21 can drive the drain tube 4 to swing during the rotation of the rotating rod 2, so that the drain tube 4 can revolve and spray the catalyst in the body 1.

[0034] In a tail gas treatment device for the production of a rice insecticide in this embodiment, by installing the cooperation of the drain tube 4 and the water spray hole 5, the catalyst can be sprayed in the body 1, and through the cooperation of the grinding wheel 6 and the grinding ring 7, the drain tube 4 can be rotated, so as to spray the catalyst in the body 1 more evenly. At the same time, since the intake pipe 8 is in a spiral shape, the tail gas can be evenly contacted with the water in the body 1, facilitating the adsorption of impurities therein, and thus improving the treatment effect of the tail gas.

[0035] The working principle of the above embodiments is as follows: When treating the exhaust gas in the body 1, the external exhaust gas enters the body 1 through the intake pipe 8 and is discharged from a plurality of exhaust holes 9. At this time, the motor 16 starts and drives the rotation, so that during the rotation of the rotating rod 2, a plurality of stirring plates 20 can be driven to stir the water source in the body 1, enabling it to evenly adsorb the impurities in the exhaust gas. At the same time, the external catalyst can enter the connecting frame 18 through the liquid inlet pipe 19 and enter the cavity 3, and enter the drainage cylinder 4 through the cavity 3 and the connecting pipe 12. The rotation of the rotating rod 2 can drive a plurality of drainage cylinders 4 to revolve through the support plate 21. When the drainage cylinder 4 revolves, the cooperation of the grinding wheel 6 and the grinding ring 7 can drive the drainage cylinder 4 to rotate, so that the catalyst sprayed through the water spray holes 5 can be evenly sprayed into the body 1, thereby enabling it to purify the exhaust gas in the body 1. The purified exhaust gas can pass through the activated carbon filter plate 10. By installing the activated carbon filter plate, the particles and odors in the exhaust gas can be adsorbed, thereby further purifying the exhaust gas in the body 1 and improving the purification efficiency of the exhaust gas.
