Problems solved by technology

[0003] The production of benomyl generally consists of a reactor, a centrifuge, a discharge device, and a mother liquor recovery device. The existing production system has the following disadvantages: the material will contain a lot of impurities or foreign matter after being discharged from the centrifuge after being processed by the reactor. When unloading, they are all discharged into the material together, which will affect the quality of the material

Abstract

The invention discloses a filter device used for benomyl production and used after reactor treatment. The filter device comprises a filter box and a centrifugal drum, wherein a buffer base is fixed atthe lower end of the filter box, an inner tooth ring is fixed in the filter box, a second sealing door is mounted on the front end surface of the centrifugal drum, a drive rotating shaft is fixed atthe upper end of the centrifugal drum, and a gear is fixed on the drive rotating shaft and meshed with the inner tooth ring. The filter device used for benomyl production and used after reactor treatment has good impurity filter effect and high rate, and the quality effect of impurities on centrifuged materials is avoided.

Description

technical field [0001] The invention relates to a filter device, in particular to a filter device after treatment in a reaction kettle for benomyl production. Background technique [0002] Benomyl is a systemic fungicide, which is metabolized into carbendazim and another volatile butyl isocyanate in plants, which are its main fungicidal substances. The pure product is white crystal with a slight odor. Insoluble in water, soluble in organic solvents, stable in dry state, will decompose and lose effect when wet. Low toxicity to humans and animals, safe to crops. Benomyl is a systemic fungicide with protective, eradicating and therapeutic effects. It has control effect on diseases caused by fungi of Ascomycetes, Deuteromycetes and some Basidiomycetes on cereal crops, grapes, pome fruits and stone fruits, rice and vegetables. It can also be used to control mites, mainly as an ovicide. Used for pre-harvest and post-harvest spraying and dipping to prevent fruit and vegetable ...
