Here, the nozzle bar is preferably provided in two symmetrical forms with respect to the center.

Reference numeral 54 is a shutoff valve installed in the nozzle bar 56.

Hereinafter will be described the operation of the present invention.

When the plating solution is prepared in the solution manufacturing tank 40, since it is heated to a considerable temperature, steam is generated inside the manufacturing tank 40.

At this time, when operating the drive motor 32, the motor shaft 33 is rotated while the power is transmitted to the pulley 26 through the pulley 38 and the belt 31 installed on the shaft circular pulley 26 is installed device The shaft 83 rotates in one direction.                     

Accordingly, the two-stage device frame 45 installed under the device circular shaft 83 rotates, so that the suction part 41 attached to the side of the device frame 45 rotates in one direction to suck the fume. do.

As the suction part 41 rotates, the suction part 41 of the second stage sucks the fume generated in the manufacturing tank 40 step by step. At this time, the fume suction capability of the fume suction guide plate 76 is increased. It is further improved.

The fume sucked into the suction part 41 passes through the inner sponge filter 71 through the hole 78 formed in the bottom perforated plate 72, and condensed water contained in the fume in the sponge filter 71 in the process. Etc. are primary filtered.

After passing through the sponge filter 71, the fume is introduced into the case 25 through the device circular shaft 83 and stays in the entire internal space up to the connecting square frame 30 which is in communication therewith. This fume is reprocessed by the outlet, which will be explained later.

Meanwhile, as the device circular shaft 83 rotates, the drive gear 27 installed on the device circular shaft 83 rotates to rotate the shaft 3 engaged with the driven gear 5.

As the shaft 3 rotates, the shaft 9 connected to the bevel gears 17 and 18 is rotated to rotate the cam 6 installed on the shaft 9 at a constant speed.

As the cam 6 rotates, the driving shaft, which is in close contact with the cam 6 via the roller 10, repeatedly moves up and down according to the gradient of the cam 6.

That is, the cam 6 pushes the roller 10 so that the driving shaft 14 connected thereto is lowered and the operation of raising and lowering again in accordance with the elastic force of the elastic spring 12 is repeated. (14) Ascending and descending the drive center shaft 48 is connected to the lower end and the connecting table (16).

Here, the driving center shaft 48 itself rotates like the device circular shaft 83, but is hinged to the connecting table 16 so as not to be disturbed by the rotation.

As the driving center shaft 48 is lowered, the pusher shafts 65 respectively connected to the driving center shafts 48 are down, and the supporters 70 and the pusher perforated plate 69 connected to the pusher shafts 65 are lowered. Descended.

Therefore, the sponge filter 71 is pressed by the descending perforated plate 69, and is compressed to squeeze and discharge the condensed water contained in the sponge filter during the fume suction process.

When the cam 6 continues to rotate, the roller 10 is moved upward by the spring 12 and operates in the opposite manner as described above, so that the support 70 and the pusher perforated plate 69 are lifted up, and the sponge filter ( 71 is swollen.

As this operation is repeated, the condensed water collected by the sponge filter 71 is introduced into the solution again, and the fume is collected and stays inside the case 25 and the connecting square frame 30. Therefore, the fume escaping to the inlet 61 of the manufacturing tank 40 can be removed widely.

On the other hand, the collected fume is condensed again by the solution sprayed in the form of mist and re-introduced into the solution.

That is, when the pump 92 is operated, the solution in the manufacturing tank 40 is sucked through the suction pipe 91 connected to the pump and is supplied through the supply pipe 93, and the solution supplied through the supply pipe 93 is It is connected to the supply pipe is supplied to the solution nozzle bar 94 installed in the connecting square frame 30 is sprayed through the spray nozzle 95 formed along the solution nozzle bar 94.

The mist sprayed in this way condenses the fume filled in the connecting square frame 30 again, and the condensed fume and the mist are moved to the case 25 connected to the connecting square frame, and then the device circular shaft (83) installed at the bottom of the case (83). Through the inside of the

And it is introduced into the nozzle bar 56 installed on the bottom of the device circular shaft 83 can be injected back into the solution in the tank through the injection nozzle (57) installed on the nozzle bar (56).

According to the discharge fume condensation apparatus of the electroplating process solution production tank according to the present invention as described above, when the chemicals are introduced into the tank, and when the chemicals are not introduced into the tank, the exhaust fume and the fume in the tank are suction-filtered and discharged to the fume dust collecting facility. This prevents the release of fumes into the atmosphere, thereby reducing air pollution.

In addition, by re-condensing the condensed water in the solution can reduce the evaporation of the solution to some extent to effect the concentration management.
