Vacuum belt filter for carbendazim production

Abstract

The invention discloses a vacuum belt filter for carbendazim production. The vacuum belt filter comprises a machine frame, a filter cloth, a rubber belt, a driving roller and a driven roller, wherein the filter cloth, the rubber belt, the driving roller and the driven roller are arranged on the machine frame. One end of the machine frame is provided with the driving roller, the other end of the machine frame is provided with the driven roller, and the rubber belt is in sleeved connection between the driving roller and the driven roller. A vacuum tank is arranged in the machine frame, an annular friction belt is arranged between the upper edge of the periphery of the vacuum tank and the rubber belt, the vacuum tank is divided into a plurality of vacuum partition cavities through partition plates in the rubber belt material-conveying direction, an ascending portion of the filter cloth is pressed and overlaid on the upper end face of the ascending portion of the filter cloth through a cloth pressing roller, and the filter cloth is sequentially connected with a discharging roller, a filter cloth conveying roller, a filter cloth tensioning device and the cloth pressing roller. A feeding device and a leaching device are sequentially arranged on the right side of the cloth pressing roller and located above the filter cloth in the filter cloth material-conveying direction. The vacuum belt filter is simple in structure, improves product quality, is good in filtering effect, effectively protects the filter cloth and intelligently controls vacuum degree.

Description

technical field [0001] The invention relates to the technical field of pesticide processing and production, in particular to a vacuum belt filter for carbendazim production. Background technique [0002] The vacuum belt filter is a kind of filter cloth or filter screen as the medium, so that the slurry is horizontally arranged on the filter medium, and the solid-liquid separation is realized by making full use of the slurry gravity and vacuum suction. The vacuum belt filter is suitable for materials under various concentration conditions, and has high filtration efficiency, so it is preferred by many industries. The existing defects of the belt vacuum filter are: the filtration efficiency is low, the washing effect is poor, and the best running state of the filter cannot be guaranteed; When the slurry is distributed on the filter cloth of the vacuum filter, the suction and filtration effect is often very poor; during the operation, the vacuum degree required by the belt fil...

AI Technical Summary

Problems solved by technology

The existing defects of the belt vacuum filter are: the filtration efficiency is low, the washing effect is poor, and the best running state of the filter cannot be guaranteed; When the slurry is distributed on the filter cloth of the vacuum filter, the suction and filtration effect is often very poor; during the operation, the vacuum degree required by the belt filter is generated by the operation of the supporting water-gas separator and vacuum pump. The level of vacuum is related to the quality of the filtration effect, and the degree of vacuum depends on the air output of the vacuum pump. Usually, the operation of the air output is manually controlled by the staff. Due to the differences in the operating level of the operators, it is impossible to ensure that the water supply is stable and can be adjusted at any time. The thickness of the material layer adjusts the air output
