Raw material screening device for desulfurization catalyst production

Abstract

A raw material screening device for desulfurization catalyst production comprises a device body and a base, the base is fixed to the bottom of the device body, four discharging pipes penetrate through the outer surface of the device body, and an operation panel is installed in the middle of the outer surface of the device body. According to the raw material screening device for desulfurization catalyst production, homogenizing plates and a rotating shaft are arranged, the homogenizing plates are detachably connected with the output end of a motor through the rotating shaft, in use, a worker opens a dustproof cover and pours materials into a feeding port, at the moment, the motor is started, and enables the homogenizing plates to rotate through the rotating shaft, so as to control the quantity of the materials, and therefore excessive accumulation of the materials is avoided; and when wet raw materials adhere to dead corners between the homogenizing plates, the worker turns off the motor, detaches the rotating shaft and the output end of the motor, scraps off the materials at dead corners and performs drying treatment, and therefore use is convenient.

Description

technical field [0001] The invention relates to the technical field of desulfurization catalyst raw material screening, in particular to a raw material screening device for desulfurization catalyst production. Background technique [0002] With the continuous deepening of industrialization in various countries in the world, SO pollution has surpassed smoke pollution to become the largest pollutant in the atmospheric environment. Flue gas desulfurization (FGD) is different from other desulfurization methods. It is the only large-scale commercial application of desulfurization method in the world, and it is the most effective and main technical means to control acid rain and SO pollution. [0003] The surface of the desulfurization catalyst is active, can catalyze oxidation, can promote the direct reaction of SO2, accelerate the dissolution of CaCO, promote the rapid oxidation of CaSO to CaSO, strengthen the precipitation of CaSO, reduce the liquid-gas ratio, reduce the calciu...

AI Technical Summary

Problems solved by technology

[0005] The existing desulfurization catalyst raw material screening equipment will control the raw materials through the feed valve or the uniform material plate during screening to avoid the accumulation of raw materials, but the feed valve or the uniform material plate will be fixedly installed with the main body of the device, while the screening When feeding materials, it is inevitable to encounter wet materials, which are easy to adhere to the dead corner of the equalizing plate and the feed valve, which is inconvenient to clean. In addition, the existing screening devices are vibrating screens through vibrating motors, which will cause vibration The frame and the main body of the device collide and rub, making noise and causing wear at the same time
