Abstract

The utility model discloses an induction-type static eliminator, solving the problems that the static electricity brings hidden troubles and accidents to a plurality of industries, etc. The utility model is characterized in that a discharging need is connected with the earth via a sheet metal; in addition, a static insulating sleeve is coated on the sheet metal for avoiding that the intersect static induction is formed by that an operator or a machine part adjacent to the induction-type static eliminator contacts the sheet metal in the process of static elimination. The induction-type static eliminator has the advantage of simple structure, favorable effect of the static elimination, etc is an ideal static elimination device for industries such as petroleum, chemical engineering, textiles, paper making, etc.

Description

Industion type electrostatic charge eliminator

A kind of device of eliminating static especially is applied to the induction type Xelminator of industries such as oil, chemical industry, rubber, weaving, papermaking.

Static can be human service, as static application technologies such as xerography aspect certain.But in a lot of industries, the small electrostatic spark that static produced is again to set off an explosion and the immediate cause of fire.And in general production process, the energy of static will directly hinder normally carrying out of some production, even influence the quality of some product.As, in fiber process and printing industry because the effect of static electric field power, cause respectively in entanglement, fracture of wire and the printing process in the fabrication processes paper be attached together register trouble, fold unevenly, influence is faults such as printing and printing quality continuously.Utilize high voltage source between spray point and earth electrode, to produce highfield though 86104480 of application numbers are called " auto-discharge type pulse charging electrostatic cleaner ", corona discharge take place, in and static.But this static eraser corona is strong, and promptly discharge spark is big, can produce harmful ozone and nitrogen dioxide during work, and is unsuitable for the environment of explosion hazard.Therefore, the suitable industry of this device is few, cost is high, is difficult for extensive use.

The utility model purpose, design a kind of simple in structure, cost is low, static is eliminated effectively, is applicable to the induction type Xelminator of multiple industry.

The utility model technical solution is, utilize electrostatic induction to make the conductor new principle that distributes of loading that powers on, upper surface at the static carrier, hang the spray point that several link to each other with ground, make it on the static carrier surface, induce the charges of different polarity, and form electric field between the static carrier, corona discharge take place, in and static.Realize the induction type Xelminator of this scheme, its concrete structure is: spray point links to each other with ground by the metallic plate of different shape; Be with on the metallic plate, (resistivity is greater than 10 by insulative material ¹⁰) the static insulating cover made.The purpose that the static insulating cover is set is, prevents to eliminate in the electrostatic process, and operator or the machine part adjacent with this device contact with metallic plate, forms the effect of paying that electrostatic induction brought that intersects.

The utility model advantage:

1, do not need high voltage source, simple in structure, cost is low, corona intensity is suitable, static is eliminated the efficient height.

2, the metallic plate in this device can be made different shapes according to different industries and purposes, and the static that can be widely used in explosion environment and general industry is eliminated, and reaches the purpose of removing a hidden danger, improve the quality of products.

Below in conjunction with description of drawings the utility model most preferred embodiment.

Fig. 1 is this apparatus structure schematic diagram.

Fig. 2 is the structural representation that this device is used for the electrostatic precipitation aspect.

In Fig. 1～2,1 is that spray point, 2 is that metallic plate, 3 is that static insulating cover, 4 is that fixed screw, 5 is earth connection.

In actual applications, static elimination process is as follows:

When spray point 1(can be materials such as conductive fiber, conductive fabric) when the static carrier, its internal charge redistribution, the result is the spray point 1 near the static carrier side, its most advanced and sophisticated position induces the electric charge different with the static carrier; The electric charge identical with the static carrier appears in the afterbody of spray point 1, and this electric charge is through metallic plate 2(or metal bracelet 6) and earth connection 5(earth resistance below 1K Ω) introducing is underground; And form electric field between the electric charge at spray point 1 most advanced and sophisticated position and the static carrier, when local electric field strength surpassed the 25-30 kv/cm, air was ionized, and formed corona discharge.The charges of different polarity to the static carrier movement, make the static on it obtain neutralization under electric field action.

Claims

1, a kind of induction type Xelminator that comprises spray point, it is characterized in that: spray point 1 links to each other with ground by metallic plate 2.
