Problems solved by technology

The transmission of powder in the pipeline may be stagnant and blown away alternately. Therefore, the accuracy of the powder output by the powder feeder cannot guarantee the stability of the powder output at the outlet of the pipeline after being transported through the pipeline. For stable transmission, it is necessary to detect the state of powder transmission in key parts of the pipeline
[0005] Studies have shown that in the field of pneumatic conveying technology, powder concentration has a very important influence on the formed gas phase. At present, pneumatic conveying devices mainly focus on how to solve the technical problems mentioned above, but for the conveying object, that is, powdery materials or powder Concentration detection also failed to attract enough attention

Abstract

The invention relates to an electronic control system of a pneumatic conveyor. The electronic control system can be an electrical control cabinet or an electrical control device. The pneumatic conveyor comprises a base, a material bin, a feeding inlet, a first discharging pipe, a first fan, a first feeding pipe and the like. The electrical control device comprises an industrial personal computer and an electric valve. The electric valve is arranged at the connector between the pipeline and a second material collection pipe. A rated powder concentration value range is set on an input panel of the electrical control device. When a measured powder concentration value is smaller than a rated concentration value, a tool wheel spindle motor is controlled, the rotation speed is increased until the measured powder concentration value reaches the rated concentration value, and then collection work is conducted. The electronic control system of the pneumatic conveyor improves work efficiency, and the automation degree of a machine is improved.

Description

technical field [0001] The invention relates to the technical field of pneumatic conveying, and more specifically, the present invention relates to an electric control system for a device for pneumatically conveying materials. Background technique [0002] Pneumatic conveying device, also known as pneumatic lifting system, is a device that uses the energy of air to continuously convey and lift powdery bulk materials (cement, fly ash, slag powder, clinker, etc.). Traditional mechanical lifting equipment has the advantages of large lifting capacity, rich types of lifting, and high lifting height, and is widely used in various industries in today's society. However, it also has many disadvantages that cannot be underestimated. The price of the equipment is high, the one-time investment is large, the amount of maintenance is large, it is difficult to operate, the weight of the equipment is large, the investment in civil engineering is large, the area is large, and it is restrict...
