Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an electrostatic precipitator used for industrial purposes, building air conditioning, etc.

BACKGROUND ART As shown in FIGS. 3 to 5, a conventional electrostatic precipitator of this type includes a support plate 102 fixed to a dust collection section frame 101 by welding or the like, and an electrode plate support supporting a charged electrode plate 103. It is insulated and supported between the metal fitting 104 and the metal fitting 104 by an insulator 105. The charged electrode plate 103 is supported by a rod 106 and a spacer 107 at regular intervals, and the rod 106 is fixed to the electrode plate support fitting 104 with a nut 108.
The electrical connection between the charged electrode plate 103 and the electrode plate support fitting 104 is maintained. Further, the ground electrode plate 109 is similarly supported by a rod 106 and a spacer 107 at regular intervals, and is fixed with a nut 108. 110 is a nozzle for blowing air onto the insulator 105.

Problems that the invention attempts to solve In such a conventional configuration, nozzle 1 is periodically
Even if the insulator 105 is air-blown by the insulator 10, the back side of the insulator 105 is not completely cleaned as shown by the hatched area in FIG. Therefore, if the insulator 105 is left for a long time, dust will accumulate on the insulator 105, resulting in poor insulation, and the insulator 105 will eventually have to be manually wiped.

This invention solves these problems,
The purpose of this invention is to provide an insulator whose back side can be thoroughly cleaned without wiping with hands.

Means for Solving the Problem In order to solve this problem, the present invention is such that an insulator is rotatably mounted on a bearing, and a brush fixed to an actuator such as an air cylinder is brought into contact with the insulator. It is configured as an electrostatic precipitator that can be mounted freely.

Function: With this configuration, when cleaning an insulator, if the brush is brought into contact with the insulator and moved by activating an actuator such as an air cylinder, the insulator will also rotate as the brush moves due to the contact pressure, and the entire surface of the insulator can be cleaned. becomes.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Reference numeral 1 denotes an insulator, which has a shaft 2 protruding from both ends, and is rotatably sandwiched via a bearing 3 between an electrode plate support fitting 4, which is a live part, and a support plate 5, which is a ground part. The charged electrode plate 6 is supported at regular intervals by a rod 7 and a spacer 8, and is fixed to the electrode plate support fitting 4 with a nut 9 to maintain conduction. On the other hand, the ground electrode plate 10 is similarly supported at regular intervals by the rod rod 7 and the spacer 8, and is fixed to the dust collection part frame 11 with a nut 9 to maintain continuity, and the dust collection part frame 11 is grounded by a contact piece (not shown). has been done. Also, 12 is the housing 1
A brush is slidably attached to the air cylinder 3 and is driven by an air cylinder 14. Furthermore, brush 1
It is important that the length of insulator 2 (l in the figure) is longer than the circumference of insulator 1.

In the above configuration, when cleaning the insulator 1, when the brush 12 is moved in the direction of the arrow in FIG. 2 by the air cylinder 14, the brush 12 and the insulator 1
The insulator 1 also rotates due to the contact pressure, and the brush 12 comes into contact with the insulator surface. In this embodiment, the brush 12 is moved by the air cylinder 14, but the effect is the same even if the dust collecting part (that is, the insulator) is moved.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, the insulator that insulates and supports the live part and the ground part of the electrostatic precipitator is made rotatable by a bearing, and the brush is brought into contact with the insulator. By moving the insulator while moving, it is possible to thoroughly clean the back side of the insulator, so there is no need to perform tasks such as wiping your hands, and the effect is great.
