Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to an electrostatic precipitator. In this case, the electrostatic precipitator can easily adjust the positions of the dust collecting disk and the discharging member which are repeatedly arranged, so that the precision of the initial assembly and replacement work is improved without being influenced by the skill of the worker. The discharge member 20, the dust collecting disk 30, the plate 40, and the like in order to flexibly cope with the above-described problems, and to achieve modularization capable of changing the structure vertically and horizontally.

The electrostatic dust precipitator according to the present invention includes a plurality of discharge members 20 disposed inside a dust collecting chamber 10 in which an inlet 12 and a discharge port 14 are formed and charging the fine particles with a negative polarity, And a plurality of dust collecting disks 30 arranged between the driving shaft 32 and the (+) polarity rotating together with the driving shaft 32 to collect the charged fine particles. The dust collecting disk 30 is mounted on the drive shaft 32 as a circular plate and is rotated collectively by the operation of the drive shaft 32. The dust collecting disk 30 is coupled to the drive shaft 32 with a loose fitting tolerance. So that the driving force is transmitted by the engagement of the key 34 while the shaft hole 31 is formed. At this time, the drive shaft 32 is connected to the power source including the motor and is rotated.

Here, the loosely fitting tolerance of the shaft hole 31 is set to be within a range of maximum 60 ° with respect to an imaginary line in which the dust collecting disk 30 coupled on the driving shaft 32 is replaced with the driving shaft 32 at right angles 1 and 2, the key 34 is formed on the drive shaft 32 and the shaft 34 is coupled to the shaft hole 31 by the engagement of the key 34. [ A state in which a key groove is formed)

The dust collecting disk 30 is maintained at a predetermined interval during rotation by the plate 40. The plate 40 is formed with a cutout groove 42 at a predetermined interval so as to sandwich the dust collecting disk 30 therebetween.

2 to 3, the plate 40 is provided so as to keep the dust-collecting disk 30 at intervals in two places on the upper left and the lower right and one place in the center on the right side. In this case, The incision groove 42 is formed to be 1 to 30% shorter than the radius of the dust-collecting disk 30 so that the dust-collecting disk 30 scrapes the particulate collected on the surface during rotation, The removal efficiency for the fine particles is improved.

3, the plate 40 provided at the right side is used as a scraper. However, the present invention is not limited to this, and the radius of the dust disk 30 may be divided by the number of plates 40, ) Cutting grooves 42 are formed so as to be in contact with the radii so that the load applied when removing the fine particles collected on the surface of the dust-collecting disk 30 is dispersed in the respective plates 40.

Since the plurality of dust collecting disks 30 are inserted into the drive shaft 32 and the gap is maintained by the plate 40, precision machining of the coupling portions of the drive shaft 32 and the dust collecting disk 30 is not required, Even though the diameter of the dust collecting disk 30 is reduced and the durability due to warping is reduced to secure a large dust collecting area, the edge portion of the plate 40 is accommodated in the cutting groove 42, Since it is supported at the point, it has the advantage of always being precisely rotated at the designated position.

Since the distance between the dust collecting disk 30 and the discharging member 20 is always kept constant by the plate 40, fire and equipment damage due to a short circuit is prevented even if the voltage (power) is increased to increase the dust collecting efficiency .

The plate 40 is disposed on the body frame 16 to adjust the position of the discharge member 20 in the left and right direction by an adjusting screw so that the plurality of dust collecting disks 30) are collectively adjusted so that the accuracy of the initial assembly and replacement of the dust-collecting disk 30 is improved without being influenced by the worker's skill.

The dust collecting disk 30 is spaced apart by at least two plates 40 and the incision grooves 42 are formed in the plate 40 at an inclination angle so as to maintain the dust collecting disk 30 at an inclined angle. 3, the dust collecting disk 30 is spaced apart by a total of three plates 40. At this time, the cutting grooves 42 of the plate 40 located at both ends of the drive shaft 32 are inclined at mutually opposite angles The dust-collecting disk 30, which is sandwiched and held by the incision groove 42 as it is formed, is maintained at the same inclination angle as the incision groove 42 during rotation.

Accordingly, the contaminated air introduced through the inlet 12 of the dust collecting chamber 10 is increased in frictional resistance by the inclination angle of the dust collecting disk 30, that is, the contaminated air conveyed to the dust collecting disks, And collides with another dust-collecting disk via a discharge member. As a result, particulate matter is rapidly charged to the negative polarity and is easily collected on the dust-collecting disk 30 having a positive polarity, The air current in the dust collecting chamber 10 is caused to flow in the zigzag direction by reversely orienting the inclination direction of the dust collecting disk 30 of the dust collecting chamber 10 adjacent to each other when the dust collecting chamber 10 is constructed in the double layer structure and the double layer construction, There is an advantage that the dust collecting disk 30 does not concentrate the airflow and disperses it to the whole area to enlarge the dust collecting area.

The cutout groove 27 is formed at the same interval as the cutout groove 42 of the plate 40, The entrance of the incision groove 27 may be formed so as to be extended at an inclination angle so as to facilitate entry.

The gap maintaining bar 26 is positioned to be longitudinally adjustable by adjusting screws at a position adjacent to the guide rod 24 so that the plurality of discharge members 20 can be moved by a single gap maintaining bar 26, When the dust-collecting disk 30 is set at an inclination angle as shown in FIG. 5, the cutting groove 27 of the gap-maintaining bar 26 is inserted into the cut groove 42 of the plate 40 It is preferable that they are formed at the same inclination angle.
