Alternating current powder charge eliminator and powder delivery pipeline charge eliminating system

Abstract

The invention relates to an alternating current powder charge eliminator and a powder delivery pipeline charge eliminating system and belongs to the field of static elimination. In the powder deliverydirection, an oblique base is arranged for a powder delivery pipeline; a nozzle is arranged on the oblique base, and a pin seat sleeves the nozzle; a discharge pin is arranged in the pin seat, and anair supply duct is arranged on the side face of the discharge pin, a gas joint seat is arranged on the pin seat; the gas joint seat, the air supply duct, the nozzle, the oblique base and the powder material delivery pipeline are sequentially communicated through gas channels; a casing is arranged on the pin seat, and a circuit board is arranged in the casing; one end of the circuit board is electrically connected with ta high-voltage end connector, and the other end of the circuit board is electrically connected with the tail end of the discharge pin; the high-voltage end connector is electrically connected to with an alternating current power source; the parts, containing the circuit board, of the casing and the pin seat, are filled with epoxy glue to fix and seal the high-voltage end connector, the circuit board and the discharge pin to form a whole. The universality of the eliminator on pipelines of different diameters is achieved. The eliminator can be widely used in the design and manufacture field of static elimination devices for powder delivery systems.

Description

technical field [0001] The invention belongs to the field of static elimination, and in particular relates to a static elimination device and an elimination system used in the process of powder storage and transportation. Background technique [0002] In the process of powder storage, transportation and loading and unloading operations, due to frequent contact and re-separation between materials and pipe walls, container walls, and material particles, there will be an obvious electrostatic electrification process. [0003] Charged combustible materials will easily cause combustion and explosion with the accumulation of static electricity. [0004] Therefore, timely and accurate monitoring and elimination of particle static electricity has become a very important topic in the field of static electricity research and industrial control. [0005] The ion air pipeline powder static eliminator provides a good way to solve this problem. It applies a high voltage to the electrode ...

AI Technical Summary

Problems solved by technology

[0007] 1. The ion output characteristics cannot be adjusted, which makes the power dissipation efficiency unsatisfactory;

[0008] 2. The ion air outlet of the consumer is easily blocked by powder, and the structural design needs to be improved;

[0009] 3. The body of the consumer and the pipe are integrated, which is inconvenient to manufacture, install and use, and only applies to pipes with a single diameter; the consumer must be remanufactured for pipes with different diameters;

[0010] 4. The safety and reliability of the eliminator body and safety control system need to be further improved
