The process needs to measure the conveying amount of the sawdust per unit time under a certain spiral rotating speed, then determines the flow rate of the activating agent according to the proportion requirement of the sawdust and the activating agent solution, but when the rotating speed of the spiral conveyor needs to be adjusted to adjust the conveying speed of the sawdust, the flow rate of the activating agent cannot be determined to what extent, so that the accurate mixing ratio of the sawdust and the activating agent cannot be determined, and the adsorption performance of the activated carbon product is influenced. At present, there is a patent report of a material mixing device for wood chips and an activating agent, for example, the utility model 'a proportioning mixing device for wood chips and an activating agent in a chemical method activated carbon manufacturing process' with application number 201620273283.1, the mixing device is operated intermittently, and has no facility for heating and preserving heat of materials, the temperature of the materials is low, the phosphoric acid solution has poor infiltration effect in wood chip fiber tissues, so that the subsequent activation effect is influenced, and the materials mixed at each time are transferred to a feeding device of a rotary activation furnace, which is troublesome. Therefore, there is a great need for a continuous automatic mixing apparatus for wood chips and activating agents, which can accurately adjust and determine the mixing ratio of wood chips and activating agents according to the adsorption performance requirement of activated carbon products. Based on this background, the utility model discloses a continuous automatic blending mixing apparatus of saw-dust and phosphoric acid solution in chemical process system active carbon technology.
