Technical Field

The invention relates to the field of chemical powder packaging and static elimination, in particular to a temperature control ion wind type chemical powder packaging process static detection and elimination device.

Background

The existing chemical powder packaging system is not provided with an electrostatic elimination facility, and most of chemical powder packaging operations adopt manual bagging operation. The friction between the slices and the conveying pipeline, and the direct friction and collision process between the slices and the packaging bags can generate a large amount of static electricity. Generally, chemical powder has high insulation and large electrostatic dissipation time constant, so that the electrification of the chemical powder is not easy to eliminate, and when the powder is discharged from an overhead bin, a large amount of static electricity is still carried. In addition, during the blanking and packaging process, static electricity can be generated due to direct friction and collision between the slices and the packaging bag, and meanwhile, the packaging bag is poor in conductivity and stripping electrification can be generated when the plastic bag with the lining is separated. When the charged body is an electrostatic nonconductor, in general, an electric shock is felt when the electric potential is discharged to a human body at 30kV or more. When manual bagging operation is carried out, electrostatic ignition of the packaging bag and electric shock of operators often occur, so that normal packaging operation is seriously influenced, and even fire and personnel injury accidents can occur.

The accident hidden danger can be caused by incomplete static elimination, so that a plurality of people put forward a plurality of static elimination methods and measures for the problem, and the main measures adopted at home at present are as follows:

Electrostatic grounding: static electricity is led to the ground through the conducting wire, and the conducting wire has a good conducting effect on static electricity on a conductor or free static electricity on metal. An operator wears an anti-static bracelet, a worktable surface is connected with a static earth wire and the like, and the method can only eliminate the static electricity of a conductor and is not suitable for eliminating the static electricity on an insulator.

Humidifying: the relative humidity is reduced by 50-60%, the temperature is 20-25 ℃, an electrostatic environment is easy to generate, and the electrostatic charge can be eliminated by increasing the air humidity under the same environmental temperature, so that the method is very large in investment.

Electrostatic shielding: in the place where the static electricity sensitive element exists, the static electricity sensitive element is often exposed to the area where the static electricity exists during the storage or transportation process, and the static electricity shielding method can be used for weakening the external static electricity. The most common methods are electrostatic shielding bags and electrostatic shielding turnover boxes, etc.

Ion neutralization: the insulator is easy to generate static electricity in the air, and the static electricity on the insulator is eliminated, so that the static electricity grounding method is ineffective, and charged ions are neutralized by adopting equipment such as an ion fan or an ion air gun in a working environment.

Packaging bag static eliminator: the working principle is that the electrostatic field automatic balancing ion injection mode is adopted, the generated positive and negative ions are emitted to the surface of a charged medium, and charges opposite to the medium are attracted by the charges on the surface of the medium, so that the medium surface moves to generate charges with the same quantity and opposite polarity to neutralize the static charges generated on the surface of the woven bag.

The methods have respective defects, and at present, no static electricity eliminating system capable of comprehensively eliminating static electricity carried by materials and packaging bags exists in China.
