DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a drainage device for a surface treatment machine, such as a Parker treatment machine, a plating treatment machine, an etching treatment machine, which performs a surface treatment on a work.

(Prior Art) For example, as shown in FIG. 3, the Parker treatment machine includes a degreasing tank 100, a first water washing tank 102, a second water washing tank 104, a film forming tank 106,
The first washing tank 108 and the second washing tank 110 are arranged side by side,
The work 112 is conveyed by various methods such as a turntable method, a trolley conveyor method, and a crane method, and these are sequentially dipped in the tanks 100 to 110 to form a chemical conversion film on the surface thereof. .

In such a Parker processing machine, the washing tanks 102, 104, 108, 11
The methods for treating wastewater from 0 are generally shown in Figs.
It is as shown in the figure. Among them, in the system shown in FIG. 4, the flow of washing water is set from the second washing tank 104 or 110 to the first washing tank 102 or 108, and the pipe 114 is connected to the first washing tanks 102 and 108. Then, the wastewater from each washing tank is guided to the wastewater collecting tank 116, and the wastewater collected in the wastewater collecting tank 116 is sent to the wastewater treatment section by the pump 118 to be purified and then discharged to the outside.

On the other hand, the method shown in FIG.
The pan 120 is used to receive the waste water from the washing tank, guide it to the waste water collecting tank 116, and then discharge it to the outside in the same manner as described above.

(Problems to be solved by the invention) However, in the case of the method shown in FIG. 4, not only piping work is required, but also many impurities, especially in the film forming tank, are generated in the drainage water from the washing tank. Since the solid content called so-called sludge is included, the pipes are easily clogged, which requires periodic and frequent cleaning.
Meanwhile, the operation of the equipment must be stopped. Further, if the pipe is clogged, the drainage will not be performed smoothly, which causes a problem that water overflows from the washing tank.

On the other hand, in the case of the pan receiving type of FIG. 5, there is no problem such as clogging of piping, but a large pan 120 that covers the whole of the plurality of tanks 100 to 110 is required, which increases the equipment cost and There is a problem that the area occupied by the equipment becomes large.

(Means for Solving the Problem) The present invention has been made to solve such a problem, and its gist is to use a plurality of water tanks of a surface treatment machine for surface-treating a workpiece by immersing it in a liquid. In the drainage device of the type that temporarily collects the wastewater of the wastewater into the wastewater collection tank and discharges it through the post-wastewater treatment unit, the wastewater collection tank is arranged adjacent to the water tank that is the final step of the water flow among the plurality of water tanks. That is, the waste water from the water tank in the final step is caused to overflow and transferred to the waste water collecting tank.

(Operation and effect of device) As described above, in the present invention, since the drainage from the water tank is transferred to the drainage collecting tank by overflow, piping for connecting the water tank and the drainage tank is not necessary, and therefore the piping The problem that the water in the water tank overflows from the tank does not occur due to the clogging of the tank, and the cleaning work for removing or preventing the clogging of the piping is not necessary, and the operation rate of the apparatus is improved.

Further, unlike the system shown in FIG. 5, a large bread is not required, so that the area efficiency of the entire equipment is improved and the equipment cost is reduced.

(Example) Next, an example in which the present invention is applied to a drainage device in a Parker processing machine for metal works will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 10 denotes a circular drainage collecting tank, and a degreasing tank 12, a first water washing tank 14, a second water washing tank 16, a film forming tank 18, a first water washing tank so as to surround the drainage collecting tank 10. 20, a second washing tank 22 is provided. As shown in the figure, in this example, each of these tanks 12, 14, 16, 18, 20, 22 and the drainage collecting tank 10 have an integrated structure, and they are partitioned by a common partition wall.

In the second water washing tanks 16 and 22, small capacity water supply chambers 28 and 30 defined by partition plates 24 and 26 are formed, and water from a water supply source is supplied to these water supply chambers 28 and 30. It has become so. The wash water supplied to the water supply chambers 28 and 30 is
The second washing tank 16,22 through the lower openings 32,34 of the partition plates 24,26.
Flows into the body of.

On the other hand, in the first washing tanks 14 and 20, intermediate chambers 40 and 42 defined by partition plates 36 and 38 are formed.
The washing water from 6,22 is led to the intermediate chambers 40,42 through the overflow ports 44,46 formed by notching the upper part of the common partition wall, and further from the lower openings 48,50 of the partition plates 36,38. The first flush tanks 14 and 20 are adapted to flow into the main body portions thereof, respectively.

On the other hand, in the circular drainage collecting tank 10, the first washing tank 1
Overflow ports 52, 54 are formed by partially cutting out the upper part of the common partition wall with 4, 20, and the drainage water from the first washing tanks 14, 20 is discharged through the overflow ports 52, 54. It is about to overflow.

In the drainage device of this example, the cleaning water from the water supply source is in the direction opposite to the direction in which the work is conveyed, that is, from the water supply chambers 28 and 30 to the second water washing tanks 16 and 22 and the intermediate chambers 40 and 42 and the first water washing. Sequentially flowing to the tanks 14, 20, and from the first washing tank 14,20 which is the final step of the flow into the drainage collecting tank 10 through the overflow ports 52, 54, and then to the outside through the purification treatment section. Is released.

In this example, the degreasing tank 12, the first washing tank 14, the second washing tank 1
6, the film forming tank 18, the first water washing tank 20, the second water washing tank 22 and the drainage collecting tank 10 have an integrated structure in which they are partitioned by a common partition wall. It is much more compact than the. Further, in the device of this structure, the degreasing tank 12, the water washing tanks 14, 16, 20, 22, the film forming tank 18 and the like are arranged in a circle, and the space in the central portion is used as it is as the drainage collecting tank 10. Compared to the case where the drainage collecting tank 10 is independently provided, there is a feature that there is less waste and that the space can be effectively used. Incidentally, in this example, the degreasing tank 12 and the film forming tank 18 may not be integrated with the washing tanks 14, 16, 20, 22 and may be provided independently.

In the above embodiment, the washing tank is arranged in a circle around the drainage collecting tank, but it is also possible to arrange these in a row in the lateral direction. FIG. 2 shows an example thereof. In the figure, 56, 58, 60, 62 and 64 are the second washing tank, the first washing tank, the drainage collecting tank, the first washing tank and the second washing tank, respectively, which are arranged in a row and are integrally constructed as a whole. ing. Thus, the cleaning water supplied to the water supply chambers 66, 68 flows through the lower openings 74, 76 of the partition plates 70, 72 into the main body of the second washing tanks 56, 64, and further through the overflow ports 78, 80. After reaching the intermediate chambers 82 and 84, they flow from the lower openings 90 and 92 of the partition plates 86 and 88 that define the intermediate chambers 62 and 84 into the main body of the first washing tank 58 and 62, and finally Overflow port 94,96 to drainage collection tank 6
It overflows to 0 and is then discharged to the outside through the wastewater treatment section.

In the above examples, the pipe for connecting the flush tank and the drainage collecting tank or the pan for receiving the drainage from the flush tank is not required, and thus the pipe construction and the cleaning based on the clogging of the pipe are unnecessary, and There are various advantages such as the need for space for installing bread is eliminated.

It should be noted that these are merely examples of the present invention, and the present invention can be variously modified without departing from the gist of the invention, for example, each washing tank can be independently provided and closely arranged. Can be configured with.
