Powder quantitative pneumatic feeding equipment for powder and use method thereof

Abstract

The invention relates to powder quantitative pneumatic feeding equipment and a using method thereof. The powder quantitative pneumatic feeding equipment comprises a spiral scale and an air locking rotary valve; a discharging port of the spiral scale is connected with a feeding port of the air locking rotary valve; the spiral scale comprises an extending hopper and a main hopper which are arranged up and down and communicate with each other; the bottom end of the extending hopper is fixedly connected with the top end of the main hopper; and a dust discharge port and a flexible connection interface are formed in the top end of the extension hopper. According to the powder quantitative pneumatic feeding equipment and the using method thereof, a Venturi tube is connected with the spiral scale through the air-locking rotary valve, and the air-locking rotary valve and the Venturi ejector are combined to isolate the interference of airflow on the spiral scale; and the air suction amount of the Venturi tube is adjusted through the air-locking rotary valve, air sucked by the Venturi tube is used for cleaning materials and removing dust for the spiral scale, a dust hood can remove dust for the spiral scale in real time, and therefore, the maintenance-free purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of material weighing and conveying, in particular to a powder quantitative air conveying and dosing device and a use method thereof. Background technique [0002] With the development of my country's industry, the improvement of people's living standards, the development of economy and industry, the urban environment and garbage disposal have become increasingly important, and the dust reprocessing technology generated by urban garbage disposal has emerged as the times require. This is the dust treatment after garbage treatment. During the process, the equipment that continuously measures and adds additives to the designated position according to the proportion, that is, the accurate weighing of materials, accurately weighs the materials (slaked lime) and transports them to the air conveying pipeline. However, in the prior art, during the weighing process of the screw scale, dust will be generated during the ...

AI Technical Summary

Problems solved by technology

However, in the prior art, during the weighing process of the screw scale, dust will be generated during the conveying of materials. The exhaust port on the screw scale is generally connected with a dust cover, and the air cleaned by the bag is directly discharged indoors. If the bag is blocked or damaged , the dust will not be excluded or the dust will pollute the indoor environment
