Pre-mixing type spiral powder feeding device

Abstract

The invention discloses a pre-mixing type spiral powder feeding device which comprises a rack, a plane table, weighing sensors, a box, a motor, a rotating shaft, a hollow shaft, a sealing seat, a blowing pipe, a spiral impeller, a feeding nozzle, a discharging nozzle and a controller. Raw materials and a modifier are fed into the box through the feeding nozzle, and the controller controls the motor to drive the spiral impeller fixedly connected with the hollow shaft to rotate through the rotating shaft, so that the raw materials and the modifier are continuously conveyed; meanwhile, compressed air is pumped into the hollow shaft through the blowing pipe, so that the raw materials and the modifier are blown up, and the raw materials and powder are mixed; and the raw materials and the modifier are mixed and pushed to move forwards by the spiral impeller at the same time till mixtures are discharged from the discharging nozzle, and the weighing sensors are used for weighing, so that the output amount of the raw materials and the modifier is precisely controlled. The pre-mixing type spiral powder feeding device is simple in structure, the raw materials and the modifier are mixed and pushed to move forwards by the spiral impeller at the same time so as to be mixed in advance, the subsequent modification mixing time is shortened, and modification efficiency is improved.

Description

technical field [0001] The invention relates to a powder auxiliary production device, in particular to a premixed powder screw feeding device. Background technique [0002] The powder surface is treated by physical or chemical methods, and the physical and chemical properties of the surface are purposely changed to meet the specific requirements of use. The surface modification of the powder is widely used in papermaking, Modified calcium carbonate in plastics, plastic films, chemical fibers, rubber, adhesives, sealants, daily chemicals, cosmetics, building materials, coatings, paints, inks, putty, sealing wax, medicine, food (such as chewing gum, chocolate), feed General production process: cleaning, drying, crushing, stockpiling, grinding, grading, modification, packaging. During modification production, raw materials and modifiers need to be sent to the modification equipment for stirring modification. Due to raw materials and The modifier is input into the modification ...
