Description

The safety-type ion bar

Technical field

The utility model belongs to electrostatic art, relates in particular to a kind of device that is used to eliminate static.

Background technology

The static technology for eliminating is obtaining increasingly extensive application in industries such as semiconductor, encapsulation, photoelectricity, communication, spraying, printing, weaving, medical equipment, building materials and injection mouldings.

In industries such as electronics, printing, plastic cement, weavings; needs according to production technology and device layout; run into the situation that in narrow and small, elongated working space, to carry out the static elimination through regular meeting; existing fan air-supply type static eraser often because volume is big, it disappears the electricity zone generation area of anion (promptly end) do not satisfy the needs of technology and can't be used for circular or conical.

The utility model content

Technical problem to be solved in the utility model provides a kind of safety-type ion bar, its positive and negative ion generating region field width, can carry out static to narrow and small, elongated working space and eliminate, safer with respect to fan air-supply type static eraser, the scope of application is more extensive.

The technical solution of the utility model is: a kind of safety-type ion bar is provided, comprises the power line and the spray point that are connected with power supply, it is characterized in that: a strip insulator compound bar core that is constituted by upper and lower excellent core is set; Set gradually at least two discharge aperture along its length at last excellent core, spray point is set in the discharge aperture; Between upper and lower excellent core, establish a groove, one three core high-voltage shield line is set in the groove; Left and right two heart yearns in the three core high-voltage shield lines are connected with power supply; Spray point runs through excellent core, and a heart yearn plug-in type middle with three core high-voltage shield lines is connected, and forms electric pathway; At arranged outside one " U " font of compound bar core or the conducting metal shell of approximate " U " font; The openend of conducting metal shell is positioned at a side at the discharge aperture place of compound bar core.

Further, between described two discharge aperture, pore is set, last excellent core or down excellent core or its junction surface air flue is set, tracheae is set in the air flue, tracheae is connected with pore through conduit, the tracheae while is connected with wind regime or source of the gas.

Concrete, left and right two heart yearns of described three core high-voltage shield lines are connected with high-voltage ac power.

Bottom at described spray point is provided with conical head, and conical head directly passes the insulating barrier of the middle heart yearn of three core high-voltage shield lines, inserts conductor wire core bundle wherein, forms electric pathway.

Described conducting metal shell is provided with earth terminal, and earth terminal is connected through lead with the earth terminal of power supply.

Compared with the prior art, the utility model has the advantages that:

1. discharge aperture and spray point adopt wire or strip to distribute, ion generating region field width, and generating capacity is big, can carry out static to narrow and small, elongated working space and eliminate;

2. can have source of the gas, operating distance is far away, and it is fast to eliminate static speed, and gas consumption is little;

3. the metallic conduction earthing of casing, whole device is safer, can work in to purify the higher working region of rank.

Embodiment

Below in conjunction with drawings and Examples the utility model is described further.

In Fig. 1 and Fig. 2, be provided with a strip insulator compound bar core that constitutes by last excellent core 1, following excellent core 2; Set gradually two or more at least discharge aperture 3 along its length at last excellent core, spray point 4 is set in the discharge aperture; Between upper and lower excellent core, establish a groove 5, one three core high-voltage shield line 6 is set in the groove; Left and right two heart yearns in the three core high-voltage shield lines are connected with power supply; Spray point runs through excellent core, and is connected with a heart yearn plug-in type of three core high-voltage shield lines centre, forms electric pathway; At arranged outside one " U " font of compound bar core or the conducting metal shell 7 of approximate " U " font; The openend of conducting metal shell is positioned at a side at the discharge aperture place of compound bar core.

In the bottom of spray point, conical head 4-1 is set, conical head directly passes the insulating barrier of the middle heart yearn of three core high-voltage shield lines, inserts conductor wire core bundle wherein, forms electric pathway.

The conducting metal shell is provided with earth terminal, and earth terminal is connected (not shown) with the earth terminal of power supply through lead.

A heart yearn in the middle of the three core high-voltage shield lines is because the induction effect of high voltage electric field, produces and imports power supply same frequency, wave mode is similar, amplitude is lower than input voltage value slightly voltage.Because the induced voltage effect of high voltage, little electric current, the spray point needle point produces corona, ionized air; On same needle point, send positive and negative ion, thereby can produce the effect of removing static efficient, energy-conservationly.

Through actual measurement, adopt the ion bar electrical performance indexes excellence of this kind fabrication techniques, security performance is good, is particularly suitable for working in the higher working region of purification rank.

Among Fig. 3, further, between described two discharge aperture, pore 9 is set, last excellent core or down excellent core or its junction surface air flue 9 is set, tracheae is set in the air flue, tracheae is connected with pore through conduit, the tracheae while is connected with wind regime or source of the gas.

This figure is to be provided with wind regime (being commonly called as source of the gas) with the difference of preceding figure, no matter raising is by a relatively large margin then all arranged on disappear electricity work distance, the indexs such as electricity time, the electric speed that disappears and ionic equilibrium concentration that disappear.

The utility model is specially adapted to carry out the field that static is eliminated at narrow and small working space.
