Description

Technical Field

[0001] The utility model belongs to the technical field of pesticide intermediate production, in particular to a wastewater treatment device for pesticide intermediate production. Background Art

[0002] Pesticide intermediates are a key category of fine chemicals. Essentially, they are "semi-finished products" processed from agricultural raw materials, serving as intermediates that bind two or more substances together. Pesticide intermediates can be considered synergists or "active agents" in pesticides, serving as intermediate materials in pesticide production. The production of pesticide intermediates must minimize environmental impact, making wastewater treatment crucial.

[0003] The patent "A Pesticide Intermediate Wastewater Filtering Device" (patent number: ZL202220216935.3) discloses a technical solution. A water inlet pipe and a discharge pipe are provided on the side of the above-mentioned tank body. The water inlet pipe passes through the tank body and is close to the top of the tank body. A drive motor and a storage box are provided on the top of the tank body. The drive motor is connected to a rotating shaft, which passes through the tank body and extends to the bottom of the tank body. A stirring rod and a scraper are provided on the rotating shaft. One side of the scraper is connected to the inner wall of the tank body. A discharge pipe is provided on the storage box, which passes through the top of the tank body. A water outlet pipe is provided at the bottom of the tank body. The water outlet pipe passes through the tank body. A filter screen is provided in the tank body, and one end of the filter screen is connected to the bottom of the discharge pipe.

[0004] However, there are certain certainties. For example, when wastewater enters the tank, a part of it will pass directly through the filter. After adding flocculants, flocs will be generated under the filter, resulting in incomplete filtration of impurities. A scraper is set to clean the side wall of the tank, but the cleaning effect is limited and it cannot clean the residue on the filter. Utility Model Content
