Problems solved by technology

[0004] However, since the discharge needle is surrounded by an insulator tube, there is a problem that it is difficult to clean
Especially in the case of using the static elimination device in Patent Document 1, in order to protect the discharge needle, the top of the discharge needle is retracted inwardly compared with the top of the insulator tube, so it is more difficult to clean around the electric needle
Since the discharge needle is very thin and may be broken, it must be handled with care during maintenance

Embodiment Construction

[0028] Below, according to Figure 1(a) - Figure 7 , an embodiment of the present invention will be described.

[0029] As shown in FIG. 1( a ), the static elimination device 11 includes: a main body 12 ; and a discharge needle unit 13 detachably attached to the main body 12 .

[0030] The discharge needle unit 13 includes: a rectangular plate-shaped base 21 ; four holding portions 22 provided on the lower surface of the base 21 ; and four discharge needles 23 held by each holding portion 22 . The base 21 and each holding portion 22 are integrally formed of synthetic resin. Each holding portion 22 is formed in a cylindrical shape. The holding portions 22 are arranged at predetermined intervals on a straight line along the longitudinal direction of the base 21 . Such as Figure 5 Also shown in , the proximal end of the discharge needle 23 is fixed to the distal end of each holding portion 22 by being embedded. A conical coil spring 24 is fixed on the middle part of each di...

Abstract

A neutralization apparatus (11) is provided with a pair of protective walls (60, 61) that protrude toward a neutralization object. The protective walls (60, 61) are made to sandwich therebetween a plurality of ion discharge openings (42) arranged in a single row in the neutralization apparatus (11) and extend in a straight line along the direction in which the ion discharge openings (42) are arranged. Therefore, by moving, for example, a brush along the protective walls (60, 61), the plurality of ion discharge openings (42) and discharge needles (23) can be cleaned all at once.

Description

technical field [0001] The invention relates to a static elimination device. Background technique [0002] Conventionally, there is known a static elimination device that generates ions by corona discharge by applying a high voltage to a discharge needle, and blows the generated ions onto an object to be neutralized. In this static eliminator, insulating foreign matter in the air is deposited on the discharge needle, etc., and the ion generation efficiency gradually decreases. Therefore, the discharge needle needs to be cleaned regularly. For example, the static eliminator in Patent Document 1 is configured to be capable of cleaning with a discharge needle attached to a discharge rod. [0003] Patent Document 1 Japanese Patent Application Laid-Open No. 10-125445 [0004] However, since the discharge needle is surrounded by the insulator tube, there is a problem that cleaning is difficult. Especially in the case of using the static elimination device in Patent Document 1,...
