Technical Field

[0001] The utility model relates to the technical field of pesticide production, in particular to a device for producing a pesticide intermediate oxadiazine with a waste gas dust removal function. Background Art

[0002] 3-Methyl-4-nitroiminohydro-1,3,5-oxadiazine (oxadiazine for short) is an important intermediate of the neonicotinoid insecticide thiamethoxam developed by Syngenta. It is prepared through a specific chemical process, for example, the cyclization reaction of methylnitroguanidine and polyformaldehyde under acidic conditions. The equipment used to produce the pesticide intermediate oxadiazine mainly includes a device for neutralizing the synthetic raw materials. This device is designed to achieve uniform mixing of the raw materials and scrape the material on the inner wall of the neutralization tank to speed up the discharge efficiency and avoid material waste.

[0003] Most existing pesticide intermediates, such as oxadiazines, only have a one-way neutralization function during the production process. Since waste gas containing harmful substances may be generated during the production process of pesticide intermediates, if these waste gases are directly discharged into the environment without proper treatment, they will have a serious impact on air quality, ecosystems and human health. For example, particulate matter in the waste gas may cause respiratory diseases, and organic and inorganic matter may cause water and soil pollution.

[0004] Therefore, in view of the fact that most of the existing pesticide intermediates oxadiazine only have a one-way neutralization function during the production process, and since waste gas containing harmful substances may be generated during the production process, if directly discharged, it will have a serious impact on air quality, ecosystems and human health, a pesticide intermediate oxadiazine production device with waste gas dust removal function can be designed. After the raw materials are neutralized, a smoke suction pipe is set to filter and discharge the waste gas. Utility Model Content

After stirring for a period of time, the telescopic valve 111 is gradually opened by the control of the electromagnetic control valve 112, so that the mixed raw materials can be discharged through the discharge pipe 110.

[0025] See also Figure 4-Figure 5In this embodiment, the outlet pipe 2 passes through the connecting hole 102 and penetrates into the mixing tank 1. The lower end of the fixing ring 202 is provided with a first clamping post 203 corresponding to the first clamping hole 103. The outlet pipe 2 is first passed through the connecting hole 102 and positioned and connected with the circular cover 101, so that the outlet pipe 2 penetrates into the mixing tank 1. Then the first clamping post 203 drives the fixing ring 202 to pass through the first clamping hole 103 and is positioned and connected with the circular cover 101, so that the position of the outlet pipe 2 is further reinforced. A plurality of groups of second clamping posts 207 are laterally symmetrically installed on both sides of the upper end of the receiving box 205.

[0026] During operation, the outlet pipe 2 is first passed through the connecting hole 102 and positioned and connected with the circular cover plate 101, so that the outlet pipe 2 penetrates into the mixing tank 1, and then the first clamping column 203 drives the fixing ring sleeve 202 to pass through the first clamping hole 103 and be positioned and connected with the circular cover plate 101, so that the position of the outlet pipe 2 is further reinforced, and then an appropriate amount of activated carbon is removed and evenly laid on the grid placement plate 208, and then the raw materials are poured into the mixing tank 1 through the feeding pipe 104 in turn, and finally, driven by the first motor 105, the rotating column 106 drives the stirring rod 107 to mix the raw materials evenly, and at the same time, the stirring rod 107 drives the scraper 108 to scrape along the inner wall of the mixing tank 1 to avoid waste of raw materials;

[0027] During the raw material mixing production process, waste gas containing harmful substances may be generated. The waste gas is extracted through the outlet pipe 2 by the action of the vacuum pump 201. The solid particles in the waste gas are initially filtered through the porous filter plate 209. The harmful substances in the waste gas are then further filtered through the activated carbon on the grid placement plate 208 before being discharged into the atmosphere.

After the receiving box 205 has been used for a period of time, the receiving box 205 is removed and its interior is cleaned. Then, the second clamping post 207 drives the receiving box 205 to be positioned and connected to the outlet pipe 2 through the second clamping hole 206, and the receiving box 205 can continue to be used.

[0029] After stirring for a period of time, the telescopic valve 111 is gradually opened under the control of the electromagnetic control valve 112 , so that the mixed raw materials can be discharged through the discharge pipe 110 .

[0030] Through the above steps, the raw materials are first poured into the mixing tank 1 for uniform mixing. During this process, the pesticide intermediate oxadiazine may produce waste gas containing harmful substances, which can be filtered through the outlet pipe 2 and discharged into the atmosphere. Through this method, particulate matter and harmful components in the waste gas generated during the production process can be effectively removed, reducing pollution to the atmosphere, which helps to protect the air environment and reduce the impact on surrounding residents and ecosystems. At the same time, it can also reduce the risk of workers being exposed to harmful environments, which helps to protect the health and safety of workers, and solves the problem that most existing pesticide intermediates oxadiazine only have a one-way neutralization function during the production process. Since waste gas containing harmful substances may be generated during the production process, if it is directly discharged, it will have a serious impact on air quality, ecosystems and human health.
