Description

Technical Field

[0001] This utility model relates to the field of wastewater recycling, specifically to a comprehensive treatment device for electroplating wastewater reuse. Background Technology

[0002] In existing electronic products, electroplating is often used to enhance the conductivity, corrosion resistance, and solderability of circuit boards. After prolonged use, a large amount of impurities accumulate in the electroplating solution. To ensure excellent electroplating performance, the electroplating solution needs to be replaced regularly. To prevent wastewater from polluting the environment, these wastewaters need to be recycled and purified using an integrated electroplating wastewater recycling system before discharge. The current purification process includes initial collection and filtration, neutralization, sedimentation, filtration, activated carbon treatment, and ultraviolet disinfection. Among these, sedimentation is the most time-consuming process.

[0003] When sedimentation occurs in a sedimentation tank, a long period of settling is required after adding the flocculant. After the settling is complete, a water pump or other device is used to pump the settled liquid to the next process.

[0004] As the water pump extracts water, some impurities from the bottom of the pool will gradually enter the filtration equipment due to the pump's suction, thus affecting the accuracy of the next stage. Furthermore, these impurities can damage the internal structure of the water pump, thereby affecting its lifespan. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a comprehensive treatment device for electroplating wastewater recycling, including a sedimentation tank, wherein a plurality of adjustable discharge components are provided on the side wall of the sedimentation tank, the adjustable discharge components include a plurality of semi-arc rotating rods passing through the side wall of the sedimentation tank, a fixing plate is provided on the outer wall end of the sedimentation tank to fix the shafts on both sides of the semi-arc rotating rods, and the fixing plate used for the shafts on the top surface of the semi-arc rotating rods is a detachable structure, an elastic sealing gasket is attached to the groove of the semi-arc rotating rod on the side of the sedimentation tank, a discharge port passing through the side wall of the sedimentation tank is provided on the bottom surface of the groove of the semi-arc rotating rod, and a filter screen plate passing through the side wall of the sedimentation tank is provided on the inner wall of the sedimentation tank.

[0007] As an improvement, the bottom surface of the semi-circular rotating rod groove on the side of the sedimentation tank is provided with a discharge groove for discharge, and the bottom surface of the discharge groove is provided with a liquid outlet.

[0008] As an improvement, the outlet is connected to the next stage of filtration equipment via a plastic hose.

[0009] As an improvement, the detachable fixing plate above the semi-circular rotating rod is connected to the outer wall of the sedimentation tank by a bolt structure.

[0010] As an improvement, a polygonal connecting post is provided on the top surface of the semi-circular rotating rod, and a polygonal wrench for rotating the semi-circular rotating rod is provided on the outer wall end of the polygonal connecting post.

[0011] As an improvement, the elastic sealing gasket is made of fluororubber.

[0012] The advantages of this invention compared to the prior art are as follows: This device uses a semi-circular rotating rod and an elastic sealing gasket to ensure that after sedimentation, the liquid in the sedimentation tank will be quickly discharged from the drain under the action of gravity. In order to ensure that impurities do not flow out of the sedimentation tank, a filter screen is installed in front of the drain, which can effectively filter out the impurities generated by sedimentation.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] As per the instruction manual Figure 1 , 2As shown in Figures 3 and 5, the sedimentation tank 1 is included. To ensure that the waste liquid can be drained without the need for extraction equipment, several adjustable drainage components 2 are provided on the side wall of the sedimentation tank 1. Each adjustable drainage component 2 includes several semi-circular rotating rods 21 that pass through the side wall of the sedimentation tank 1. The outer wall end of the sedimentation tank 1 is provided with a fixing plate 22 for fixing the shafts on both sides of the semi-circular rotating rods 21. To facilitate the disassembly of the semi-circular rotating rods 21, the fixing plate 22 used for the shafts on the top surface of the semi-circular rotating rods 21 is a detachable structure, and the detachable fixing plate 22 above the semi-circular rotating rods 21 is connected to the outer wall of the sedimentation tank 1 by bolts.

[0021] To ensure the sealing of the semi-circular rotating rod 21, an elastic sealing gasket 23 is attached to the groove of the semi-circular rotating rod 21 on the side of the sedimentation tank 1. To adapt to different sediments, the elastic sealing gasket 23 is made of fluororubber.

[0022] To prevent the semi-circular rotating rod 21 from completely passing through the sedimentation tank 1, which would result in the side wall of the sedimentation tank 1 being too thin, the depth to which the semi-circular rotating rod 21 passes through the side wall of the sedimentation tank 1 cannot be too deep. The remaining thickness needs to be cut out with tools such as an electric saw to create a drain outlet 24. To prevent impurities from flowing out of the sedimentation tank 1, a filter screen plate 25 that passes through the side wall of the sedimentation tank 1 is provided on the inner wall of the sedimentation tank 1.

[0023] To facilitate the rotation of the semi-circular rotating rod 21, a polygonal connecting post 211 is provided on the top surface of the semi-circular rotating rod 21, and a polygonal wrench 212 for rotating the semi-circular rotating rod 21 is provided on the outer wall end of the polygonal connecting post 211.

[0024] As per the instruction manual Figure 2 , 4 As shown, in order to facilitate the unified collection of liquid flowing out of each drain port 24, the bottom surface of the groove of the semi-circular rotating rod 21 on the side of the sedimentation tank 1 is provided with a drain trough 26 for draining, and the bottom surface of the drain trough 26 is provided with a liquid outlet 261, which is then connected to the next stage filtration equipment using a plastic hose.

[0025] In the specific implementation of this utility model, a polygonal wrench 212 is used to close all the semi-circular rotating rods 21. Then, waste liquid is added to the sedimentation tank 1, followed by the addition of a precipitant for settling. After the settling time is completed, the semi-circular rotating rods 21 are rotated to open the drain port 24, allowing the purified liquid to flow into the drain trough 26 and then out through the outlet 261. The purified liquid is then transported to the filtration equipment through a plastic hose. Finally, the filter screen 25 and the impurities at the bottom of the sedimentation tank 1 are cleaned for the next use.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
