The sludge separation unit 50 is mounted inside the main body 10, and the filter base 57 supporting the rotary filter 55 is fixed between the fixed base 60 and the main body 10. .

Referring to the internal structure of the rotary filter 55, as shown in Figure 6, the filter motor 52 is installed inside the fixed base 60, the rotation axis of the flange 64 and the bolt 66 It is connected to the external fixing plate 70, the bearing 76 is coupled to the flange 64, the bearing 76 is coupled to the fixed base 60. Therefore, the rotation operation of the motor 52 is to rotate the filter 55 mounted on the fixed base 60 to be rotatable through the bearing 76.

The rotary filter 55 has an outer fixing plate 70 of a cylindrical drum with an open top, and a nonwoven fabric 72 made of a material through which a plating solution passes, but does not pass a sludge component, and another inside thereof. The inner fixing plate 74 of the upper open cylindrical drum overlaps, and bolts 78 are fastened to the upper end thereof, and are coupled to the outer fixing plate 70. Therefore, the rotary filter 55 has a structure in which the nonwoven fabric 72 is fixed between the inner and outer fixing plates 70 and 74.

And, as shown in the exploded view in Figure 6, the outer fixing plate 70 and the inner fixing plate 74, the mesh structure has a thickness of the degree of deformation does not occur in the centrifugal force or air pressure, the non-woven fabric ( 72).

In addition, a cylindrical nozzle 80 is disposed at the center of the inner fixing plate 74, and a circular plate 82 is fitted to the outer surface of the cylindrical nozzle 80 so as to be slidable.

As shown in FIG. 7, the circular plate 82 may reciprocate along a longitudinal groove 80a formed on an outer surface of the cylindrical nozzle 80, and stoppers 84 may be formed at the end of the cylindrical nozzle 80. Although protruding, the circular plate 82 can slide along the cylindrical nozzle 80, but is separated from the cylindrical nozzle 80 so as not to escape.

In addition, the cylindrical nozzle 80 is formed coaxially to the rotary filter 55, the nozzle hole 86 is formed to gradually decrease the hole toward the outside from the inner space is formed to flow the plating solution from the inside to the outside Can be.

In addition, the present invention includes a solution support plate 92 which receives the sludge attached to the filter to drop from the main body 10 and an air cylinder 94 for horizontally moving the sludge to collect the plating solution, and the remaining sludge. It has a sludge recovery unit 90 receives.

The sludge recovery unit 90 has a pair of rails 93 mounted on the frame 5 at a lower side of the main body 10 and fixedly disposed in a horizontal direction, and a solution support plate 92 is disposed on the rails 93. And the solution recovery pipe 96 and the air cylinder 94 is seated.

5, the solution support plate 92 may move on the support rail 93 by the operation of the air cylinder 94, and the solution support plate 92 may be operated by the operation of the air cylinder 94. It may be positioned to extend to the bottom of the 10, or retreat from the bottom of the main body 10 to escape. In addition, the sludge box 98 is positioned below the solution support plate 92.

Reference numeral 120 denotes a controller 120, which is a controller for automatically controlling various driving elements according to a preset program, and may be made of a small computer or a PLC.

According to the present invention configured as described above, when the filter motor 52 rotates at a high speed, the rotary filter 55 connected to the rotating shaft rotates at a high speed inside the main body 10. At this time, when the plating solution is supplied to the solution supply pipe 22 of the plating solution supply unit 20, the plating solution is supplied from the solution supply nozzle 26 to the inside of the cylindrical nozzle 80 as shown in FIG. And leaks to the outside through the nozzle holes 86 of the cylindrical nozzle 80 due to the centrifugal force generated by the high speed rotation of the rotary filter 55.

In addition, the inside of the rotary filter 55 is discharged to the outside of the rotary filter 55 through the inner fixing plate 74 and the nonwoven fabric 72 and the outer fixing plate 70 disposed outside the cylindrical nozzle 80. Sludge remains and only pure plating solution comes out. Then, the plating solution flows downward along the inner wall surface of the main body 10, is collected in the solution support plate 92 and recovered through the solution recovery pipe 96 as shown in FIG.

When sludge of a certain weight is collected and collected by the nonwoven fabric 72 through the sludge separation process as described above, the weight check sensor 16 detects this and the control unit 120 sets a predetermined weight. When it reaches, the plating solution supplied to the solution supply pipe 22 is stopped.

After stopping the supply of the plating solution as described above, the rotation of the rotary filter 55 is continued for a predetermined time to completely dehydrate the plating solution from the sludge, and then decelerate to high speed rotation at low speed (speed at which no centrifugal force is generated). Air is supplied to the air pipe 30.

The air supplied in this way is injected from the plurality of air nozzles 46 disposed in all directions along the rotary filter 55 inside the main body 10 so that the sludge is fixed to the inner fixing plate 74 and the nonwoven fabric of the rotary filter 55. At 72.

This is because, as shown in b) of FIG. 4, the ejected air jet direction is deviated from the diagonal direction G toward the center of the rotary filter 55, where the outer longitudinal grooves 80a of the cylindrical nozzle 80 are positioned. Toward (H), the sludge adhering to the inner fixing plate 74 and the nonwoven fabric 72 of the rotary filter 55 is collected to fall to the home position of the cylindrical nozzles 80 and 109.

In this case, the longitudinal grooves 80a formed on the outer surface of the cylindrical nozzle 80 may prevent sludges from scattering in all directions inside the rotary filter 55, and in the absence of the cylindrical nozzle 80, The sludge dropped in all directions may be attached to the opposite wall surface of the rotary filter 55, but the sludge may be prevented from scattering in all directions due to the groove position H of the cylindrical nozzle 80.

As such, when the sludge separation of the rotary filter 55 is completed, the solution support plates 92 under the sludge body 10 are moved backward along the support rail 93 by the action of the air cylinder 94. Likewise, when the solution supporting plates 92 are reversed, the solution recovery pipe 96 can be expanded in a bellows form to freely operate.

Then, when the solution supply pipe 22 is lifted up by the action of the air cylinder 24 of the plating solution supply unit 20 so that the position of the solution supply nozzle 26 is the same as that of the upper cover 12, the main body 10 is opened. Rotation does not interfere with the solution supply nozzle 26.

4, the sludge collected around the cylindrical nozzle 80 is rotated by the driving of the motor 38, in which case the motor shaft gear 36 and the air shaft gear ( 34) will rotate and flip over 180 °. At this time, the air pipe 30 is connected to the rotary joint 40 so that the body 10 does not rotate even when rotated 180 ° does not cause the pipe distortion.

Meanwhile, in FIG. 5, when the main body 10 rotates 180 ° about the bearing fixing shaft 32, the upper cover 12 and the upper part of the main body 10 do not interfere with each other and may rotate.

As described above, when the main body 10 rotates 180 °, the circular plate 82 of the cylindrical nozzle 80 provided inside the rotary filter 55 may rotate the cylindrical nozzle 80 due to its own weight. Accordingly, the slide is scraped down from the surface of the cylindrical nozzle 80 to the stopper 84 while sliding.

In this way, the sludge separated from the cylindrical nozzle 80 to the bottom thereof is collected in the sludge box 98 and processed. When the sludge treatment is completed as described above, the main body 10 is rotated again, and its operation position is returned to its original position. As shown in FIG. 9, the operation is performed in the order of supply of the plating solution.

As described above, according to the present invention, the sludge component in the plating solution generated during the electroplating operation is separated from the plating solution by using the high-speed rotating centrifugal force of the rotary filter 55, and the sludge is automatically rotated at the low speed rotation. By allowing separation and withdrawal, it is possible to efficiently maintain and manage the plating solution and sludge as one apparatus.

Accordingly, the productivity of the sludge filter system is improved, and the initial cost of the facility can be reduced, and the operation and maintenance of the facility can be made simple, thereby reducing the facility maintenance cost.
