Etching process is a processing technology used to manufacture microelectronic devices such as printed circuit boards and integrated circuits. Etching wastewater is wastewater generated in this process. Etching wastewater is a hazardous wastewater that poses a great threat to the environment and human health. If it is discharged directly into natural water bodies without treatment, it will cause water pollution and damage the aquatic ecosystem; if it is treated by a sewage treatment plant, a series of physical, chemical and biological technologies need to be used to remove harmful substances such as organic matter, heavy metals and suspended solids to meet the discharge standards. For the treatment of etching wastewater, the commonly used methods include sedimentation, flocculation, flotation, activated carbon adsorption, membrane separation and other technologies. These technologies can effectively remove organic matter and heavy metals in wastewater, convert them into harmless substances or recycle them, thereby reducing pollution to the environment. At the same time, it is also necessary to strengthen environmental awareness in the etching process, adopt environmentally friendly alternatives, and reduce the generation of wastewater.

In the utility model, the staff discharges the etching waste liquid into the stirring barrel through the liquid inlet pipe, and then puts the treatment reagent into the stirring barrel, and then activates the stirring assembly to fully stir the treatment reagent and waste liquid in the barrel, so that under the cooperation of the stirring assembly, the reagent and waste liquid in the stirring barrel are fully mixed, which greatly improves the stirring efficiency and greatly enhances the treatment effect of the etching waste liquid.
[0004] However, the above practicality still has shortcomings:
[0005] After the above device completes one treatment, workers are required to add materials again. This operation is very frequent. Manual feeding is inefficient and will bring a huge workload. Utility Model Content
[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a PCB etching waste liquid treatment machine, which solves the problem that after the device has finished one treatment, workers need to feed again, which is a very frequent operation.
[0007] To achieve the above-mentioned purpose, the utility model proposes a PCB etching waste liquid treatment machine, comprising: a bracket, the top of the bracket is fixedly connected to a waste liquid storage tank, one side of the waste liquid storage tank is provided with a limiting pipe, the bottom of the limiting pipe is fixedly connected to a treatment tank body, the interior of the limiting pipe is slidably connected to a conical stopper, the bottom of the conical stopper is fixedly connected to a connecting rod, the bottom of the connecting rod is fixedly connected to a floating block, the top of the floating block is fixedly connected to one end of a telescopic rod, and the other end of the telescopic rod is fixedly connected to the inner top of the treatment tank body.
[0008] Preferably, a waste liquid inlet is provided at the top of the waste liquid storage tank, a feeding pipe is fixedly connected to one side of the waste liquid storage tank close to the limiting pipe, and the limiting pipe is fixedly connected to the bottom of the feeding pipe.
[0009] Preferably, an engine is fixedly connected to the top of the processing tank.
[0010] Preferably, a stirring power column is provided inside the processing tank body, the top of the stirring power column passes through the top of the processing tank body and extends to the outside thereof, one end of the stirring power column extending to the outside of the processing tank body is fixedly connected to the engine, and the side wall of the stirring power column is fixedly connected to a stirring rod.
[0011] Preferably, the floating block is arranged on one side of the stirring power column.
[0012] Preferably, the stirring rod is in a W-shape.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] When treating waste, a large amount of untreated waste is stored in the waste liquid storage tank. At this time, the waste liquid will flow into the limiting pipe through the feeding pipe. Because there is no waste liquid in the treatment tank at this time, the floating block will move downward, and the limiting pipe will have a gap with the conical block, and the waste liquid will flow into the treatment tank through the gap. When there is too much waste liquid in the treatment tank, the floating block will float on the waste liquid. The more waste liquid there is, the closer the floating block will be to the top of the treatment tank. At this time, the gap between the conical block and the limiting pipe will become smaller, and the speed at which the waste liquid flows into the treatment tank will slow down. The advantage of this design is that automatic loading can be completed without manual monitoring and operation. At the same time, the flow rate of added waste liquid can be changed according to the remaining amount of waste liquid in the treatment tank, which can greatly reduce the workload of workers.
