Description

Description Circulating and concentrating system for washing liquid for continuous washing equipment

According to the present invention, a cleaning liquid stored in a plurality of cleaning liquid tanks, each having a different degree of contamination, is sprayed on an injection nozzle installed toward a cleaning article suspended in a cleaning chamber according to the prior application of the present invention, and By sequentially switching and supplying the tank from a tank having a high concentration of dirt to a tank having a low concentration of dirt, the amount of the cleaning liquid used is remarkably reduced, and the concentration of the dirt component in the tank with a higher degree of dirt is further increased, thereby increasing the dirt concentration That is, regarding a washing liquid circulating concentration system that facilitates the recovery of reusable useful components,

The present invention relates to a cleaning liquid distribution system for a continuous cleaning device that has achieved compactness, maintenance-free operation, and simplified configuration of the entire device. Background art

Conventionally, for example, in order to wash off the plating liquid adhering to the product immediately after plating and the cutting oil adhering to the product immediately after cutting, the articles to be cleaned are sequentially passed through a plurality of cleaning tanks filled with the cleaning liquid. And a method of passing through a plurality of washing nozzle groups arranged in tandem.

However, this conventional method requires a large amount of cleaning solution, so the cost of processing the cleaning waste solution is high, especially when washing away the plating solution containing a highly toxic chemical, which is expensive. However, there was a problem that a large installation space for the device was required.

Therefore, the applicant of the present application has applied for patents for some inventions after various studies on a cleaning method that can minimize the amount of the cleaning liquid used.

These are disclosed as "Japanese Patent Publication No. 2-4 9 7 3 9" and "Japanese Patent Publication No. 3-4 4830", and the patented cleaning methods are such.

Among them, the outline of the cleaning system used for the cleaning method of “Japanese Patent Publication No. 3-4 4 8 3 0” will be described with reference to FIG. 9. In FIG. 5 1a is a drain port provided at the bottom, and 52 is a fresh This is an immersion type cleaning tank that stores the cleaning liquid.

53 and 54 are cleaning liquid tanks which store cleaning liquid discharged from the cleaning chamber, each having a different degree of contamination according to the degree of progress of the cleaning, and sequentially circulate them to the injection nozzles 60 in a predetermined order. It is for.

5 5 is a waste liquid reservoir for washing and draining which is very dirty at the beginning of cleaning, 70 is a cleaning article, 80 is a flow path switching valve for cleaning liquid, 81 is a valve control device, 82 is a flow meter, Reference numerals 3 and 84 denote a liquid feed pump, and a to f denote a liquid feed piping system.

The operation of the cleaning system is as follows. First, the cleaning liquid in the cleaning liquid tank 53 is supplied to the injection nozzle 60 suspended from the cleaning chamber 51 內 through the pipe a by the pump 83 and injected for a predetermined time.

The highly contaminated washing wastewater at the beginning of the injection is stored in the wastewater reservoir 55 through the pipes b and c by operating the flow path switching valve 80. Thereafter, the flow switching valve 80 is switched to return the cleaning waste liquid to the cleaning liquid tank 53 via the pipe d, and circulate and supply the cleaning liquid to the spray nozzle 60 until a predetermined time has elapsed.

After the cleaning is completed using the cleaning liquid in the cleaning liquid tank 53, the cleaning liquid in the cleaning liquid tank 54 is supplied to the injection nozzle 60 'by the pump 84 and the pipe a' to perform secondary cleaning.

In this case, the washing waste liquid is returned to the washing tank 53 via the pipes b and d at the beginning of the washing period, and after a predetermined time has elapsed, the washing liquid is passed through the pipes b and d 'by operating the flow path switching valve 80. Return to tank 54 and use for circulation.

Next, the cleaning article 70 is transferred to an immersion-type cleaning tank 52 to which fresh cleaning liquid is supplied, and is immersed for a predetermined time to completely remove dirt.

During this time, the shortage of the cleaning liquid that has been discarded by the waste liquid reservoir 55 and reduced is compensated for by supplying a new cleaning liquid that is almost clean in the cleaning tank 52 to the cleaning liquid tank 54 via the pipe e.

According to the above-described cleaning method, the intended purpose of reducing the amount of the cleaning liquid used and concentrating the cleaning liquid to facilitate the recovery and reuse of useful components is remarkably achieved. However, the use of the flow path switching valve 80 composed of a multi-way solenoid valve as the cleaning liquid flow path switching mechanism has caused a new problem to be improved. That is, (a) Since the height of the mounting part of the multi-way switching type solenoid valve including the piping system is high, the installation space for the cleaning device is required accordingly.

(b) For this reason, there are many cases where this equipment cannot be implemented even if it is desired to introduce it into an existing factory.

(c) The flow path switching valve, including its control mechanism, is too expensive to manufacture, install, maintain, and inspect.

(d) The same applies to a complicated piping system connected to the flow switching valve. This drawback becomes more pronounced as the number of wash tanks increases.

(e) Due to the structure of the valve, a residual space for washing waste liquid is inevitably generated inside the valve.Every time the valve is switched, the dirty washing waste liquid flows into the washing liquid tank and the degree of contamination is reduced. Increase.

Among the drawbacks mentioned above, the height of the device can be improved by using a slide valve instead of a solenoid valve.However, the structure is not durable and costs are reduced, including the cost of piping systems. The effect cannot be expected very much.

Accordingly, the applicant of the present application has created a new type of cleaning liquid circulation / concentration system for a continuous cleaning apparatus that does not use a solenoid valve having many disadvantages as described above, and has previously described “Japanese Patent Application No. 7-333992. 2 ”as a patent application.

As shown in FIGS. 10 and 11, the cleaning liquid circulation / concentration system according to the invention of the prior application includes a plurality of cleaning liquid tanks 53 to 56 surrounding the drain port 51 a of the cleaning chamber 51. And it is installed underneath.

The drainage port 51a is connected to a horizontally rotatable liquid guide gutter 57 by a rotating means using a motor, a belt and a pulley to form a cleaning liquid flow path switching mechanism C.

That is, the effluent discharged from the cleaning chamber 51 can be selectively flown into any of the cleaning liquid tanks 53 to 56 by appropriately rotating the liquid guide gutter 57. Reference numeral 58 in the figure denotes a group of rotation position sensors for the liquid guide gutter 57.

However, there was still room for improvement in the invention of Japanese Patent Application No. 7-339392, which was aimed at making the entire washing liquid circulation / concentration system as compact as possible. . That is, it is desirable that the height of the flow path switching mechanism C be further reduced. The belt-pulley transmission mechanism requires a lot of labor and cost for maintenance. Lack of protective measures against corrosive cleaning solutions is also lacking. And so on.

Therefore, an object of the present invention is to significantly reduce the required amount of a cleaning solution and to concentrate useful components in the cleaning solution, which are extremely excellent features of the method for cleaning an article according to the prior application of the present applicant. An object of the present invention is to provide a cleaning liquid circulating and concentrating system for a continuous cleaning apparatus, in which, in addition to the advantage of facilitating recovery, the cleaning apparatus used in this method has also been made more compact, maintenance-free, and simplified in structure.

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4 show a side view and a plan view of the configuration of the main part of the cleaning liquid circulation / concentration system of this embodiment.

That is, in the drawing, reference numeral 51 denotes a cleaning chamber, and a cleaning liquid flow path switching mechanism A is connected directly below the drain port 51a via a mounting member 59.

On the lower side of the flow path switching mechanism A, four rectangular parallelepiped cleaning liquid tanks 3 1 to 3 4 (hereinafter simply referred to as tanks) are arranged so as to surround the drain port 51 a. They are installed close to the shape.

Of these four tanks, tank 31 is a storage tank that is discharged at the beginning of cleaning and stores the heaviest cleaning liquid without circulating it.

The present invention is different from the above-mentioned prior application “Japanese Patent Application No. 7-333972” in the configuration of the flow path switching mechanism A.

Therefore, the following description will be mainly limited to the configuration of the flow path switching mechanism A.

As shown in FIG. 1, the flow path switching mechanism A is attached to the flat bottom surface of an attachment member 59 fixed to the lower surface of the cleaning chamber 51 by using a connection bolt 90 in a tightly contacted state. The schematic configuration of the flow path switching mechanism A is, as shown in FIGS. 1 and 2, rotatable in a horizontal direction around the drain port 51a, so that the liquid discharged from the drain port 51a is discharged. The four distribution tanks 3:! ~ 3 4 are equipped with a rotating distribution plate 1 which plays the role of successively flowing from the tank with the higher concentration of dirt components in the liquid to the tank with the lower concentration. , It is freely rotatable.

A motor 3 serving as a driving source of the spin distribution board 1 is mounted on a side surface of the turntable support member 2.

The rotary distribution board 1 of this embodiment is made of a metal or synthetic resin, and is made of a thick disk-shaped block. The center of the upper surface is slidably connected to the drain port 51 a of the cleaning chamber 51. A liquid inlet 4 is opened, and a liquid outlet 5 is provided at one location on the lower peripheral edge. The liquid inlet 4 and the liquid outlet 5 communicate with each other via a liquid flow passage 6 provided so as to hollow out the rotary distribution board 1.

A ring gear 7 is fitted on the outer peripheral surface of the rotary distribution board 1.

An annular packing 8 slidably in contact with the flat lower surface of the mounting member 59 is provided on the upper surface of the rotary distribution board 1 so as to surround the liquid inlet 4. Rotary disc supporting member 2, the upper half 2 A and the lower half ² B, and a structure in which is united by a connecting bolt 9.

The turntable 1 is rotatably supported by the turntable support member 2 via a bearing 10 fitted in an inner space provided in the upper half 2A.

The upper surface of the upper half 2 A of the annular casing-shaped turntable support member 2, the contact surface between the mounting member 59, and the outer peripheral surface of the upper half 2 A and the outer peripheral surface of the rotary distribution plate 1. Annular packings 11 and 12 for maintaining the liquid tightness are disposed in the annular gaps a provided between them. As shown in FIG. 2, the rotary plate supporting member 2 has a shape in which one portion of the outer peripheral surface of the circular disk is bulged as shown in FIG. 2, and this bulging portion is used as a gear box portion 2C. Yes.

The variable speed motor 3 is mounted on the side end face of the gear box 2C.

The gearbox section 2C incorporates a pair of upper and lower bearings 15 and 15 that support the gear shaft 14 of the pinion 13 that is coupled to the ring gear 7. A bevel gear 16 is fitted on the gear shaft 14.

This bevel gear 16 has another bevel gear 1 fitted on the output shaft 17 of the motor 3.

8 is combined.

Furthermore, on the outer peripheral surface of the rotary distribution board 1, a rotation position display section 21 for detecting the rotation position of the rotary distribution board 1 is attached at a total of four locations corresponding to the arrangement of the four tanks 31 to 34. I have.

On the other hand, on the lower surface of the lower half 2 B of the annular casing 2, rotation position sensors 22 are mounted at respective positions corresponding to the respective rotation position display sections 21.

As shown in FIG. 2, each rotation position sensor 22 is attached to a displaceable arc-shaped strip 23 along the circumferential direction of the annular casing 2.

The arc-shaped strip 23 is provided with a long hole 24 arranged along the arc.

Then, the bolt 2 5 was揷通in the elongated hole 2 4, by Nishitome the threaded hole of the annular casing 2, _c passage switching mechanism fixed position of the rotational position sensor 2 2 which enables fine adjustment In A, as described above, during the cleaning process of the cleaning articles 70 in the cleaning chamber 51, the cleaning liquid discharged from the liquid discharging port 51a is sequentially transferred to the multiple tanks 31 to 34. Rotation control unit of motor 3 that controls the rotation of rotation distribution board 1 (Not shown) is attached.

Next, the operation of the above embodiment will be described.

The principle of operation of the washing solution circulating concentration system according to the present invention is characterized in that, at the beginning, the amount of washing solution used can be significantly reduced, and the washing solution is concentrated to facilitate recovery and reuse of useful components. It is equivalent to that of the prior application of the present applicant.

The feature of the present invention resides in the flow path switching mechanism A as described above.

Now, it is assumed that the cleaning liquid circulation / concentration system is in operation, and that the cleaning liquid in the tank 32 is supplied to the injection nozzle 60 in the cleaning chamber 51 in the primary cleaning step.

At this time, the liquid distributor 5 of the rotation distribution board 1 is brought directly above the tank 31 by the motor 3 that operates in response to an instruction from the rotation control unit.

In this state, the cleaning liquid in the tank 32 is circulated and supplied to the injection nozzle 60.

During this time, the very dirty cleaning liquid at the beginning of the cleaning is stored in the tank 31. When the predetermined time has elapsed, the supply of the cleaning liquid is temporarily stopped, and the motor 3 is started in accordance with an instruction from the rotation control unit.

Then, the rotation of the motor 3 is transmitted through the set of bevel gears 16 and 18, the pinion 13 and the ring gear 7, and the rotation distributor 1 starts rotating.

When the rotation position sensor 22 for the cleaning liquid tank 32 attached to the lower surface of the turntable support member 2 detects the corresponding rotation position display section 21 on the rotation distribution plate 1, the detection signal indicates that the motor 3 stops.

At this time, the liquid outlet 5 of the rotary distribution board 1 is brought to a position immediately above the tank 32.

Then, the circulation supply of the cleaning liquid from the tank 32 to the injection nozzle 60 is restarted. When a predetermined time has elapsed, the supply of the cleaning liquid to the injection nozzle 60 is stopped, and the primary cleaning step is completed.

Next, the process proceeds to the secondary cleaning step.

In the initial period of this process, the liquid outlet 5 of the rotary distribution board 1 is located above the tank 32, and the cleaning liquid in the tank 33 with a lower degree of contamination is supplied to the spray nozzle 60 in a circulating manner.

Then, when a predetermined time has elapsed, the liquid outlet 5 of the rotary distribution board 1 is placed on the tank 33. After being moved, the cleaning is continued with the cleaning liquid in the tank 33 for a predetermined time, and the secondary cleaning process is completed.

Subsequently, a tertiary cleaning step using a cleaning liquid with a lower degree of contamination in the tank 34 is performed in the same manner as in the second cleaning step.

As is easily understood from FIG. 1, the flow path switching mechanism A has a structure in which the height dimension can be kept as low as possible.

As a result, the overall height of the washing solution circulating and concentrating system can be considerably reduced, and the system can be easily installed in a limited space. Further, as shown in FIG. 1, the flow path switching mechanism A has a complete liquid-tight structure as a whole. Therefore, even when using a corrosive cleaning solution, the maintenance and management of the cleaning solution can be reduced in labor and cost, and sufficient durability can be ensured.

In the above embodiment, the thickness and diameter of the rotary distribution board 1 and the shape and arrangement of the liquid flow-down passage 6 are determined by the scale of the entire washing liquid circulation / concentration system and the shape and arrangement of each component thereof. The design may be changed as appropriate.

Further, in the above-described embodiment, the rotation of the motor 3 is transmitted through the pinion and the ring gear as the rotation means of the rotation distribution board 1.

However, a combination of a worm wheel and a worm may be used instead of a combination of a ring gear and a pinion.

Alternatively, a combination of a sprocket and a chain may be used.

Next, FIGS. 5 to 8 show another embodiment of the present invention, which is different from the above embodiment in that the drainage guide member B is connected to the lower side of the flow path switching mechanism A. I have.

The discharged liquid guide member B guides the cleaning liquid discharged from the liquid outlet 5 of the rotary distribution board 1 to each liquid surface of the plurality of tanks 31 to 34 immediately below, so that the falling liquid flows on the liquid surface. It serves to prevent bouncing.

As shown in FIG. 5, the discharge guide member B includes a plurality of discharge guide members B arranged so as to be able to communicate sequentially with the liquid outlet 5 as the rotary distributor 1 of the flow path switching mechanism A rotates. In this case, a hole opening plate 41 having four liquid passage holes 42 is used as its main body.

The perforated plate 41 is connected to the lower surface of the turntable support member 2 by fastening ports 43 disposed at a plurality of locations on the periphery. A liquid-tight packing 44 is provided at a portion where the hole opening plate 41 comes into sliding contact with the rotary distribution plate 1.

An elbow-shaped liquid guide cylinder 45 is connected to the lower end of each liquid passage hole 42 for guiding the liquid discharged from the liquid outlet 5 to the liquid surface of each of the plurality of tanks 31 to 34. are doing.

Further, as shown in FIG. 8, an extension pipe 46 having a length reaching the liquid level of each of the tanks 31 to 34 is connected to each of the liquid guide cylinders 45, respectively.

Since the height of this liquid level fluctuates with time during operation of the cleaning device, the length of the extension pipe 46 is set so that the lower end of the extension pipe 46 is in contact with the liquid level even when the liquid level drops to the lowest level. . And, when the lower end of the extension pipe 46 is submerged below the liquid level, the air trapped in the pipe does not prevent the drainage liquid from flowing down. Air vent holes 46a are provided.

In this way, the discharged liquid that has fallen from the liquid outlet 5 of the flow path switching mechanism A toward the liquid surface in the cleaning liquid tanks 31 to 34 rebounds on the liquid surface, and thus the degree of contamination differs, respectively. (5) The inconvenience that the cleaning liquids in the contact tank are mixed with each other can be reliably prevented. Also, the problem that the rebound liquid adheres to the lower side of the flow path switching mechanism A can be solved. By the way, in a plating factory or the like using the system of the present invention, it is often difficult to secure a space for newly installing a cleaning liquid tank due to a series of additional facilities in the past.

In such a case, if the extension pipe 46 is effectively used, the washing liquid tank can be freely installed in a place separated from the washing room 51 without restriction on the distance. Industrial applicability

As is clear from the above description, the cleaning liquid circulation / concentration system for the continuous cleaning apparatus according to the present invention can significantly reduce the required amount of the cleaning liquid, By increasing the concentration of useful components, the cost of wastewater treatment as a countermeasure against pollution and the effect of greatly reducing the cost of recovering useful components in the wastewater are greatly reduced. As described below, more excellent effects can be obtained. (a) The remarkable reduction in the height of the flow path switching mechanism makes it possible to fit the entire cleaning liquid circulating and concentrating system in a limited space.

(b) Therefore, it is easy to upgrade or remodel the cleaning equipment at the existing factory.

(c) Since the flow path switching mechanism has a completely liquid-tight structure, the labor and cost for maintenance and management of parts replacement and the like can be saved, especially when handling corrosive cleaning liquids.

(d) Also, since it has sufficient durability, the investment in the washing liquid circulation and concentration system can be significantly reduced.

(e) Further, by connecting the drainage guide member to the lower surface of the flow path switching mechanism, various inconveniences caused by the drainage that has fallen on the liquid surface of each washing liquid tank can be reliably eliminated.

(f) Even if the installation space for the washing liquid tank is limited, the extension pipe can be used to freely install the tank even at a location away from the washing room.
