Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electroplating wastewater reuse, in particular to a continuous water supply structure for reusing electroplating wastewater. Background Art
[0002] The aviation industry and mechanical processing industry usually have electroplating processes. Electroplating is a highly polluting process in the industry with high water consumption and discharge volume. In addition, the electroplating wastewater contains a large amount of heavy metals. In order to meet the environmental protection requirements of zero emissions, the electroplating wastewater needs to be treated before subsequent processes. The commonly used method is to set up an electroplating wastewater treatment station, treat the wastewater according to the reuse rate index requirements of the wastewater reuse, and the water quality of the treated reused water can theoretically meet the index requirements of the reused water, and then send the reused water to the clean water tank, and then send the reused water from the clean water tank back to the production line for reuse, but in actual production, there is no specific means to ensure that the water quality of the reused water must meet the production requirements. Unqualified water quality will affect product quality, so it is necessary to sample the reused water for testing, and it can only be reused after the water quality test is qualified. The above operation makes the reuse process interrupted and discontinuous, and the treated reused water needs to be tested and qualified before it can be reused after entering the clean water tank, so it is impossible to inject new reused water into the clean water tank, that is, the actual reuse situation is to fill the clean water tank with reused water first, and then reuse it after the water quality test is qualified, and it is impossible to continuously inject water, so the reuse of electroplating wastewater is more cumbersome and costly, so there is very little reuse of treated electroplating wastewater. The utility model provides a continuous water supply structure for reusing electroplating wastewater to solve the above problems. Utility Model Content

[0015] The following will be combined with the drawings of the specification to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0017] like Figure 1As shown, a continuous water supply structure for reusing electroplating wastewater includes a first reuse pool 1, a second reuse pool 2, a first water quality monitor 3, a second water quality monitor 4 and a control box. The first reuse pool 1 and the second reuse pool 2 are arranged in parallel, and the first water quality monitor 3 and the second water quality monitor 4 are respectively arranged on the first reuse pool 1 and the second reuse pool 2. The control box is connected to the first reuse pool 1, the second reuse pool 2, the first water quality monitor 3 and the second water quality monitor 4.
[0018] The utility model is installed at the end of the wastewater treatment process of the electroplating anodizing production line. During normal operation, all valves on the first reuse pool 1 and the second reuse pool 2 are in a closed state. When water replenishment is required, the valve on the water inlet pipe of the first reuse pool 1 is first opened to replenish the first reuse pool 1 with water. When the first reuse pool 1 starts to replenish water, the water quality of the reused water in the first reuse pool 1 is tested, and the test is continuously maintained. After the water is replenished to a high level, the valve on the water inlet pipe of the first reuse pool 1 is closed, and the valve on the water inlet pipe of the second reuse pool 2 is opened at the same time to replenish the second reuse pool 2 with water, and the water quality of the reused water in the second reuse pool 2 is started to be tested. After the water is replenished to a high level, the valve on the water inlet pipe of the second reuse pool 2 is closed After the reused water in the first reuse pool 1 is filled and the water quality test is qualified, the valve on the outlet pipe of the first reuse pool 1 is opened to supply the reused water in the first reuse pool 1 to the production line. When the reused water in the first reuse pool 1 reaches a low water level and the water quality test of the reused water in the second reuse pool 2 is qualified, the valve on the outlet pipe of the first reuse pool 1 is closed, and the valve on the outlet pipe of the second reuse pool 2 is opened to continuously supply water. Then, the first reuse pool 1 is replenished with water and the water quality test is performed at the same time. The above operation is circulated to realize that the reused water is tested first and supplied to the production line after it is qualified. The first reuse pool 1 and the second reuse pool 2 are standby for each other, thereby realizing a continuous and uninterrupted supply of reused water and ensuring stable water use for the production line.
[0019] The detection of the reused water in the first reuse pool 1 and the second reuse pool 2 continues throughout the entire water replenishment process. When the monitor finds that the water quality is unqualified during the water replenishment, the valve on the water inlet pipe is immediately closed to stop the water replenishment, and the return pipe is opened to return the reused water to the wastewater treatment system for further treatment. After the treatment is qualified, the first reuse pool 1 and the second reuse pool 2 are replenished with water. At the same time, after the water inlet pipes on the first reuse pool 1 and the second reuse pool 2 are closed, the water replenishment is completed and no more water replenishment is completed, and the monitor will open the outlet pipe to send the reused water to the production line only after the water quality test is completely qualified. Through the above operations, the water quality of the reused water in the first reuse pool 1 and the second reuse pool 2 is guaranteed to remain qualified, and the water replenishment test is carried out simultaneously, which effectively saves time and strictly controls the reuse of unqualified water.
[0020] The first reuse pool 1 and the second reuse pool 2 are both provided with an inlet pipe, an outlet pipe and a return pipe, and the inlet pipe and the return pipe are connected to the wastewater treatment system. The inlet pipe is used to replenish water from the wastewater treatment system to the first reuse pool 1 and the second reuse pool 2, and the return pipe is used to return the reused water that fails the water quality test in the first reuse pool 1 and the second reuse pool 2 to the wastewater treatment system for further treatment. The outlet pipe is connected to the production line, and is used to send the reused water that passes the water quality test in the first reuse pool 1 and the second reuse pool 2 to the production line for reuse. The inlet pipe, the outlet pipe and the return pipe are all provided with valves, and the valves are solenoid valves.
[0021] The control box controls the operation of the entire structure. The control box receives data sent by the liquid level meter, the first water quality monitor 3 and the second water quality monitor 4, and after calculation, controls the opening and closing of the solenoid valves on the water inlet pipe, the water outlet pipe and the return pipe to realize the operations of water replenishment, water return and reuse, and finally realizes the continuous and uninterrupted reuse of recycled water to the production line.
[0022] Furthermore, the first reuse pool 1 and the second reuse pool 2 are both provided with liquid level gauges for detecting high water levels and low water levels in the first reuse pool 1 and the second reuse pool 2. When the water level is low, the water inlet pipe is opened for water replenishment, and when the water level is high, the water outlet pipe is opened for reuse.
[0023] Furthermore, the control box is connected with the liquid level meter, the valve, the first water quality monitor 3 and the second water quality monitor 4 .
[0024] Furthermore, the first water quality monitor 3 and the second water quality monitor 4 both include a hexavalent chromium monitoring module, a total chromium monitoring module, a nickel monitoring module, a cadmium monitoring module and a COD monitoring module, which automatically monitor the water quality in the first reuse pool 1 and the second reuse pool 2 in real time.
[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
