Description

Technical Field

[0001] The utility model relates to the technical field of waste water and waste gas recovery, in particular to a device for collecting electroplating waste water and waste gas. Background Art

[0002] Electroplating is a process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. This process applies an electric field in the plating solution to deposit the cations of the metal to be plated in the plating solution on the cathode (i.e. the workpiece to be plated) to form a metal film. During electroplating, the plating metal or other insoluble materials serve as the anode and the workpiece to be plated serves as the cathode. The cations of the plating metal are reduced on the surface of the workpiece to be plated to form a plating layer. The electroplating solution is usually composed of an aqueous solution containing a compound of the plating metal, conductive salts, buffers, pH adjusters and additives.

[0003] A large amount of wastewater and waste gas are usually generated during the electroplating process. Since chemical solutions are used in electroplating, wastewater and waste electricity are dangerous, so they need to be cleaned and recycled in time. However, conventional treatment methods can only treat wastewater or waste gas separately, and cannot treat waste gas and wastewater at the same time, which greatly reduces the efficiency of wastewater and waste gas treatment. Conventional wastewater is treated by activated carbon to adsorb harmful substances in the wastewater, but activated carbon is generally placed in a treatment box, which is cumbersome to replace, resulting in a decrease in the efficiency of filtering wastewater.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model.

[0024] Among them, the filter box 12 is provided with evenly distributed partitions, and the partitions are arranged in a staggered manner. Activated carbon is arranged in the filter box 12. The staggered partitions increase the movement path of the exhaust gas, so that impurities in the exhaust gas are adsorbed more thoroughly.

[0025] Furthermore, the wastewater treatment structure includes evenly distributed columns 13, a wastewater purification box 14, and a waterproof board 15. The bottom end of the column 13 is fixedly connected to the top of the outer wall of the wastewater purification box 14, the top of the wastewater purification box 14 is through-connected to the connecting pipe 7, and the waterproof board 15 is fixedly connected to the inner wall of the wastewater purification box 14.

[0026] Among them, the wastewater treatment structure is to make the wastewater in the electroplating tank 6 flow from the connecting pipe 7 to the wastewater purification box 14. Under the action of the staggered waterproof plates 15, the wastewater is treated more thoroughly and finally discharged from the outlet pipe 8.

[0027] Furthermore, the top of the column 13 is fixedly connected to the bottom of the outer wall of the electroplating tank 6, the bottom of the wastewater purification box 14 is connected to one end of the outlet pipe 8, the other end of the outlet pipe 8 passes through the outer wall of the box body 1, and the waterproof plates 15 are staggered.

[0028] Among them, a movable activated carbon plate is arranged on the staggered waterproof plate 15, so that the wastewater can flow on the activated carbon plate for a longer time, and the substances in the wastewater can be absorbed more thoroughly.

[0029] Furthermore, a sealing door 17 is provided on the outer wall of the wastewater purification box 14 , and a bolt 18 is threadedly connected to the sealing door 17 .

[0030] A rubber sealing pad is arranged on the outer wall of the sealing door 17 to prevent the wastewater in the wastewater purification box 14 from flowing out. The bolt 18 passes through the sealing door 17 and is threadedly connected to the outer wall of the wastewater purification box 14 .

[0031] Furthermore, a limiting hole 16 is provided on the side of the limiting door 9, a sliding hole 19 is provided on the outer wall of the box body 1, a spring 21 is fixedly connected to the inner wall of the sliding hole 19, a limiting column 20 is slidably connected to the inner wall of the sliding hole 19, one end of the spring 21 is fixedly connected to the outer wall of the limiting column 20, and the position and size of the limiting column 20 are adapted to the position and size of the limiting hole 16.

[0033] Working principle: First, we can put the electroplating materials through the water injection pipe 2 and the filling port 3. Then, during the electroplating process, when waste gas is generated, we can start the vacuum pump 4 to inject the waste gas in the electroplating tank 6 into the filter box 12 from the suction pipe 10. Then, the filtered gas from the filter box 12 is discharged from the outlet pipe 5. Then, for the waste water generated after electroplating, we need to open the valve to discharge the waste water from the connecting pipe 7 to the wastewater purification box 14. The waste water is filtered by the waterproof board 15 and finally discharged from the outlet pipe 8.

[0034] When the activated carbon plate needs to be replaced, the limit column 20 can be manually pulled backward to make the limit column 20 move in the sliding hole 19 and squeeze the spring 21. After the limit column 20 is away from the limit hole 16, the limit door 9 can be opened, and then the bolt 18 can be loosened to take out the sealing door 17, and the activated carbon plate can be replaced. After replacement, it can be installed again, so that the exhaust gas and wastewater can be treated at the same time, and no exhaust gas and wastewater will be directly discharged. The treatment efficiency of wastewater and exhaust gas is greatly improved, and the replacement of activated carbon is simpler, which greatly increases the efficiency of filtering wastewater.
