PURPOSE:To obtain an inexpensive, lightweight throwaway type dust collecting unit by a method wherein the dust collecting electrodes for charging dusts in the air with a positive electricity by corona discharge for dust collection are formed into a plurality of honeycomb-like constructions by bonding alumi num foil to the entire surface of a nonflammable paper. CONSTITUTION:Dust collecting electrodes 3 are provided which charge dusts in the air with a positive electricity by corona discharge so as to collect the dusts. The dust collecting electrodes 3 are formed into a plurality of honey comb-like constructions by bonding aluminum foil 2 to the entire surface of a nonflammable paper 1. As a result, an expensive, lightweight throwaway type dust collecting unit can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a dust collection unit that collects dust and the like.

Conventional Technology In recent years, dust collection units that collect dust and the like are troublesome to clean, and are desired to be inexpensive, disposable, lightweight, and compact.

A conventional dust collection unit will be explained with reference to FIGS. 3 and 4.

As shown in the figure, the dust collection unit 11 includes a plurality of honeycomb (regular hexagonal) dust collection electrodes 12 made of aluminum or the like. A cylindrical anode rod 13 having a spherical suction end is provided at the center of the honeycomb-shaped dust collecting electrode 12, and a needle-like discharge needle 14 is installed at the tip on the suction side.

Furthermore, a DC high-voltage power source 15 is connected to the anode rod 13 and applies a high voltage of (1) and (e) to the dust collecting electrode 12, respectively.

In the above structure, when the air flow 16 containing dust particles is blown by a blower (not shown), the discharge needle 14 is connected to the anode rod 13, so a high voltage of (3) is applied. ,
Corona discharge occurs between the discharge needle 14 and the dust collecting electrode 12. Dust particles that have flowed into the area where this corona discharge is occurring are charged to 9cm by the corona discharge. The charged dust particles are attracted to the dust collecting electrode 12 applied to e by the electric field generated between the anode rod 13 and the dust collecting electrode 12, and are collected on the dust collecting electrode 12.

Problems to be Solved by the Invention When the conventional dust collection unit 11 is used for a long time, a large amount of dust particles are trapped in the dust collection Wi 12, and the dust collection power decreases, so depending on the place of use, the conventional dust collection unit 11 must be cleaned about once a month. There is a need to. In addition, the dust particles collected on the dust collection electrode 12 are difficult to wash off, and there is a problem in that it takes a lot of effort to wash them.

In addition, since the dust collecting electrode 12 is usually formed of metal such as aluminum, it is very heavy and large, which not only causes inconvenience when cleaning, but also when handling the dust collecting unit 11 for maintenance etc. However, it also causes inconvenience, is expensive, and is not suitable for disposable use.

The present invention was made in view of the above-mentioned problems, and is an inexpensive, lightweight, disposable type of dust collector by forming a honeycomb shape of aluminum foil glued onto the surface of non-combustible paper and using it as a dust collection pole. The purpose is to provide units.

A means to solve the problem? In order to achieve the above object, the first means of the invention is to charge dust particles in the air to ■ by corona discharge, to provide a dust collection electrode, and to attach the dust collection electrode to the entire surface of non-combustible paper with aluminum foil. and form into multiple honeycomb shapes.

The second method is to adhere electrode plates with a) V foil adhered to the entire surface of noncombustible paper at equal intervals on the front and back surfaces of each electrode plate when laminating them, and when the laminated electrode plates are unfolded, , the precepts are shaped almost like a honeycomb.

Operation The present invention has the above-mentioned structure, and the first means is as follows:
Since the dust collection electrode is formed by bonding aluminum foil to non-combustible paper, it is lighter and less expensive than a) one that uses a V-board. As for the second method, since the stacked electrodes are expanded to form the dust collecting electrode, it can be stored in a stacked state with a small volume.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 and 2.

Note that the same parts as those in the conventional example are given the same numbers and the description thereof will be omitted. As shown in the figure, in the first means,
The dust collection electrodes 3 are constructed by bonding aluminum foil 2 to the entire surface of the non-combustible paper 1 and forming them into a plurality of honeycomb (regular hexagonal) shapes.

When the above structure is pressed and the airflow 16 containing dust particles is blown by a blower (not shown), the dust particles are charged to ■ due to the corona discharge generated between the discharge needle 14 and the dust collecting electrode 3. The charged dust particles are attracted to and collected by the dust collecting electrode 3 by the electric field generated between the anode rod 13 and the dust collecting electrode 3.

In the second method, the dust collecting electrode 3 is made of a non-combustible paper 1 with aluminum foil 2 adhered to the entire surface, and each electrode plate 4 is laminated.
The front and back surfaces of the electrode plates 4 are adhered at equal intervals so that when the laminated electrode plates 4 are unfolded, they form a substantially honeycomb shape.

In the above structure, the dust collecting means performs the same operation as the first means. When storing the dust collection electrode 3, the electrode plates 4 can be folded and stored in a stacked state.

Effects of the Invention As described above, according to the present invention, aluminum foil is applied to the entire surface of non-combustible paper! iji: t & let me. By using several honeycomb-shaped dust collectors, it is possible to provide a cheap and disposable dust collection unit. In addition, the dust collection tilt, which is a replacement part, can be folded and stored in a compact state when stored, which is a great advantage for dormitory use.
