[0002] PCB board is a printed circuit board, which is the support of electronic components and the carrier of electrical connection of electronic components. It is composed of an insulating substrate, connecting wires and pads for assembling and welding electronic components. It has the functions of conductive circuits, carrying electronic components and insulating substrates. In the process of PCB board production and manufacturing, it is usually necessary to design the circuit board first, and then carry out multiple links such as board making, drilling, electroplating, etching, solder mask, silk screen printing, etc. In the process of PCB production, the substrate will be copper plated, copper coated, polished and etched. In the process of polishing the copper-plated PCB board, a large amount of cleaning waste liquid containing copper powder will be generated. These waste liquids will consume a lot of water if discharged directly, and will also cause waste of copper and environmental pollution. In order to reduce the cost of use and reduce the pollution caused by emissions, it is necessary to recycle the metal in the washing water and treat the washing water so that the washing water can be used again.

[0006] By adopting the above technical solution, large debris and metal objects in the cleaning water can be filtered through the filter plate.

[0010] By adopting the above technical scheme, the block-shaped protrusions between the first sedimentation tank, the second sedimentation tank, and the third sedimentation tank can restrict the flow of the plate washing water and prevent it from flowing out. The horizontal and vertical fixed design of the first sedimentation tank, the second sedimentation tank, and the third sedimentation tank can reduce the usage area for sedimentation of the washing water, so that the fine impurities and metals in the washing water can be gradually precipitated, which is convenient for the next step of treating the washing water, and the metals can be separated, which is convenient for subsequent removal from the first sedimentation tank, the second sedimentation tank, and the third sedimentation tank for recycling.

[0011] Preferably, a water inlet is installed through one end of the third sedimentation tank away from the second sedimentation tank, and the water inlet is lower than the height of the third sedimentation tank, and a drainage valve is fixedly installed on the side surface of one end of the third sedimentation tank.

[0012] By adopting the above technical solution, when the cleaning water is higher than the height of the water inlet, it will automatically flow into the water inlet, and the water in the third sedimentation tank can be removed by opening the drain valve during cleaning and maintenance.

[0013] Preferably, a storage box is fixedly installed on the outer surface of the base plate, and the interior of the storage box is inclined, an observation window is inlaid on the outer surface of one end of the storage box, and the observation window is located at the lowest point of the storage box, and an electromagnetic valve drain outlet is fixedly installed at the lowest point of the storage box.

[0014] By adopting the above technical solution, the water level inside the storage box can be checked through the observation window, and the dirt condensed after the addition of the agent can be concentrated together through the inclined surface of the storage box, and the condensed dirt can be regularly discharged through the electromagnetic valve drain port to ensure the cleanliness of the storage box.

[0015] Preferably, a rotating mechanism is provided between the third sedimentation tank and the storage box, and the cleaning water injected into the storage box can be stirred and evenly mixed with the reagent through the rotating mechanism.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the PCB board cleaning water recycling equipment:

[0024] 1. When the cleaning water is discharged into the liquid inlet box, the water will flow and flush along the inclined surface of the filter plate, so that large debris and metal items in the cleaning water can be filtered and concentrated together. After that, the electric push rod can be started regularly to enable the push plate to move with the cover, so that the concentrated debris and metal items can be pushed out of the liquid inlet box, and the debris and metal items can be pushed out from the discharge port and enter the inside of the receiving box, which is convenient for preliminary filtration of the cleaning water and collection and recovery of useful metals;

[0025] 2. After the plate washing water is filtered and enters the first sedimentation tank, the fine powder and dirt in the washing water will flow and settle along the first sedimentation tank. When the water level rises, it will overflow and flow into the second sedimentation tank, and then flow into the third sedimentation tank after the second sedimentation tank is full. It can separate the fine dust and impurities. The circular design of the first sedimentation tank, the second sedimentation tank, and the third sedimentation tank can reduce the floor space during use, making it convenient to shovel out the metal from the first sedimentation tank, the second sedimentation tank, and the third sedimentation tank for recycling;

[0026] 3. As the water level in the third sedimentation tank rises, water will be discharged into the storage tank through the water inlet. The inflowing water will drive the paddle to rotate, so that the paddle can drive the stirring rod to rotate together, so that the reagent can be discharged into the valve. The discharged reagent can be integrated with the cleaning water faster, speeding up the condensation speed of the debris in the cleaning water, and using the water flow to accelerate the processing speed of the cleaning water;

[0027] 4. When the water in the storage tank rises, the float will rise with it, allowing the float to move up and down with the slide rod, so that the oil in the cleaning water can be intercepted by the float. After that, the oil pump can be started at a fixed time so that the pumping bar can absorb the oil floating on the surface of the cleaning water and discharge it from the storage tank, making it easier to clean the floating oil.

[0041] The overall levelness of the equipment can be adjusted and leveled by adjusting the feet 2 on the outer surface of the bottom plate 1, so that the cleaning water can move in a specified direction during subsequent treatment of the cleaning water.

[0044] A discharge port 11 is fixedly opened on the outer surface of one end of the liquid inlet box 3 away from the push plate 9, and a cover 10 is threadedly installed on the outer surface of the push plate 9. The end of the cover 10 close to the electric push rod 8 is inclined, and the outer surface of the cover 10 is tightly fitted with the outer surface of the discharge port 11.

[0045] The sealing cover 10 can prevent the cleaning water from flowing into the liquid inlet box 3 and out of the liquid inlet box 3, and the sealing cover 10 will be moved together with the pushing plate 9, so that the debris can be pushed out from the discharge port 11 and enter the inside of the receiving box 12, so that the debris in the liquid inlet box 3 can be cleaned regularly, and can pass through the inclined surface of the sealing cover 10, so that the sealing cover 10 can automatically return to its original position when it is reset.

[0046] A first sedimentation tank 5 is fixedly installed on the outer surface of the liquid inlet box 3, and a second sedimentation tank 6 is laterally fixed on one end of the first sedimentation tank 5 away from the liquid inlet box 3, a third sedimentation tank 7 is vertically fixedly installed on the outer surface of one end of the second sedimentation tank 6, and the third sedimentation tank 7 is fixedly connected to the liquid inlet box 3, a block-shaped protrusion is provided between the first sedimentation tank 5 and the second sedimentation tank 6, and a block-shaped protrusion is provided between the second sedimentation tank 6 and the third sedimentation tank 7, and the first sedimentation tank 5, the second sedimentation tank 6 and the bottom plate 1 are fixedly connected.

[0047] After being initially filtered, the cleaning water will flow into the first sedimentation tank 5, and then into the second sedimentation tank 6 and the third sedimentation tank 7. The block-shaped protrusions are arranged so that the cleaning water will not flow out of the first sedimentation tank 5, the second sedimentation tank 6 and the third sedimentation tank 7. The horizontal and vertical design of the first sedimentation tank 5, the second sedimentation tank 6 and the third sedimentation tank 7 can reduce the area of ​​use, making the equipment more compact, and can precipitate smaller debris and metals in the cleaning water. During subsequent recycling, the metals and other debris can be taken out from the first sedimentation tank 5, the second sedimentation tank 6 and the third sedimentation tank 7 for recycling.

[0048] A water inlet 13 is installed through one end of the third sedimentation tank 7 away from the second sedimentation tank 6 , and the water inlet 13 is lower than the height of the third sedimentation tank 7 . A drainage valve 25 is fixedly installed on the side surface of one end of the third sedimentation tank 7 .

[0049] The cleaning water flows into the interior of the storage box 16 through the water inlet 13, and the drain valve 25 can be opened to release the cleaning water during maintenance and cleaning.

[0050] A storage box 16 is fixedly installed on the outer surface of the base plate 1, and the interior of the storage box 16 is designed to be inclined. An observation window 28 is embedded in the outer surface of one end of the storage box 16, and the observation window 28 is located at the lowest point of the storage box 16. An electromagnetic valve drain outlet 21 is fixedly installed at the lowest point of the storage box 16.

[0053] When the cleaning water flows into the storage box 16 through the water inlet 13, the paddle 14 will be pushed and drive the stirring rod 15 to rotate, so that the reagent discharged through the reagent discharge valve 26 can be more fully mixed with the cleaning water, thereby accelerating the mixing speed of the cleaning and reagent removal and improving the efficiency of the chemical reaction.

[0054] A slide rod 17 is fixedly installed inside the storage box 16, and a float 18 is installed through the outer surface of the slide rod 17, and the float 18 and the slide rod 17 are slidably connected, a pumping bar 19 is fixedly installed on the side surface of the float 18, an oil pump 20 is fixedly installed on the side surface of the storage box 16, and the oil pump 20 and the pumping bar 19 are connected to each other, a waterproof contact switch 24 is fixedly installed on the outer surface of the slide rod 17, and the waterproof contact switch 24 is located above the float 18.

[0055] As the cleaning water in the storage box 16 rises, the float 18 will rise along with it, so that the pumping bar 19 can always be level with the liquid surface to intercept the oil stains floating on the surface of the cleaning water. By timed starting of the oil pump 20, the pumping bar 19 can extract the floating oil stains so that the oil stains can be discharged from the storage box 16. At the same time, as the water in the storage box 16 rises, the float 18 will move in the direction of the slide rod 17 and contact the waterproof contact switch 24, so that the water pump 22 can be started to discharge the processed cleaning water and prevent the water from overflowing due to overfilling.

A long groove 27 is provided on the outer surface of one end of the base plate 1 close to the filter 23.

[0057] After the water pump 22 is started, the cleaning water in the storage box 16 will be pumped out and filtered through the filter 23, so that the small amount of condensate that is pumped out can be filtered, and when the filter 23 is cleaned, the long groove 27 can effectively prevent the cleaning water from remaining on the outer surface of the base plate 1, reducing the chance of rust on the base plate 1, and preventing the condensate from being pumped out, and the treated cleaning water can be used again to reduce the cost of use.
