Description

Technical Field

[0001] This utility model belongs to the technical field of etching solution recovery equipment, and in particular relates to a ferric chloride etching solution regeneration and recycling equipment. Background Technology

[0002] Ferric chloride etching solution is widely used for etching metal materials in industrial production processes such as printed circuit board manufacturing and metal processing. After a period of use, the etching ability of the etching solution gradually decreases, requiring regeneration treatment to restore its etching performance and recover valuable components.

[0003] Traditional ferric chloride etching solution regeneration and recycling equipment typically uses a return water pipe to continuously flow the used etching solution back to a water tank for regeneration. However, this type of equipment generally suffers from inadequate liquid level monitoring: because the etching solution is continuously flowing back, operators find it difficult to accurately monitor the liquid level in the tank in real time. If the tank is not stopped in time when it is about to be full, the etching solution can easily overflow.

[0004] This problem has several negative impacts: First, the overflow of etching solution directly wastes raw materials, reduces the amount of etching solution that can be recycled, and increases production costs. Second, the overflowing etching solution is corrosive and may cause corrosion damage to the equipment itself and the surrounding environment. In addition, operators need to frequently monitor the water tank level, which increases labor costs, and manual monitoring is subject to the risk of delayed response, making it impossible to fundamentally avoid the overflow problem. Utility Model Content

[0005] The purpose of this invention is to provide a ferric chloride etching solution regeneration and recycling equipment, which aims to solve the technical problem in the prior art that if the etching solution is not detected and stopped in time, it is easy for the etching solution to overflow from the water tank, reducing the amount of etching solution recovered and increasing the production cost.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0035] In one embodiment of this utility model, such as Figures 1-3 As shown, a ferric chloride etching solution regeneration and recycling equipment is provided, including a base frame 1, a water tank 2, an electrical control box 3, a return water pipe 4, a first diversion mechanism 5, a second diversion mechanism 6, an outlet water pipe 7, and a detection mechanism 8.

[0036] The base frame 1, serving as the basic support structure of the equipment, is welded from high-strength steel to ensure the overall stability of the equipment. The water tank 2 and the electrical control box 3 are both fixedly installed on the base frame 1. The water tank 2 is used to store and process the returned ferric chloride etching solution, and its interior forms a return cavity 21, which provides space for the temporary storage and diversion of the etching solution.

[0037] The return water pipe 4 has an L-shaped design, with one end extending through the side wall of the water tank 2 into the return cavity 21, and the other end extending outside the water tank 2 to connect to external etching equipment, introducing the used ferric chloride etching solution into the water tank 2. The L-shaped design allows for more flexible installation of the return water pipe 4, adapting to different external piping layouts. The return water pipe 4 is equipped with an electric valve 41, which is electrically connected to the electrical control box 3. The flow rate of the etching solution in the return water pipe 4 can be controlled via the electric valve 41 and the electrical control box 3.

[0038] Both the first diversion mechanism 5 and the second diversion mechanism 6 are connected to the water tank 2 and are used to divert and discharge the treated etching solution from the water tank 2. The first diversion mechanism 5 includes a first diversion pipe 51, a first diversion valve 52, and a first diversion pump 53. One end of the first diversion pipe 51 is connected to the return chamber 21 of the water tank 2, and the other end is connected to the outlet pipe 7. The first diversion valve 52 and the first diversion pump 53 are both fixedly installed on the first diversion pipe 51, and the first diversion pump 53 is electrically connected to the electrical control box 3, which controls its start and stop. In this embodiment, two first diversion valves 52 are provided, installed on both sides of the first diversion pump 53 respectively, forming dual control and improving the reliability of the operation of the first diversion mechanism 5.

[0039] Similarly, the second diversion mechanism 6 includes a second diversion pipe 61, a second diversion valve 62, and a second diversion pump 63. One end of the second diversion pipe 61 is connected to the return chamber 21 of the water tank 2, and the other end is connected to the outlet pipe 7. The second diversion valve 62 and the second diversion pump 63 are both fixedly installed on the second diversion pipe 61. The second diversion pump 63 is electrically connected to the electrical control box 3 and is controlled by the electrical control box 3. Two second diversion valves 62 are also provided, installed on both sides of the second diversion pump 63 respectively.

[0040] The detection mechanism 8, used to prevent etching solution overflow, includes a first level sensor 81, a second level sensor 82, and an alarm 83. The first level sensor 81 is installed at the bottom of the water tank 2 to monitor the low level of the etching solution within the tank. The second level sensor 82 is installed at the top of the water tank 2, slightly below the upper edge of the tank, to monitor the high level of the etching solution. Both the first and second level sensors 81 and 82 are electrically connected to the electrical control box 3, enabling real-time transmission of the detected level signals. The alarm 83 is installed on the outer casing of the electrical control box 3 and electrically connected to it, emitting an audible and visual alarm signal under the control of the electrical control box 3. When the low level of the etching solution in the water tank 2 exceeds the second level sensor 82, the electrical control box 3 controls the alarm 83 to issue an audible and visual alarm and controls the electric valve 41 to close, cutting off the flow of etching solution and preventing overflow.

[0041] Among them, the first liquid level sensor 81 and the second liquid level sensor 82 can be submersible liquid level sensors. Their core components (probe, cable sheath) are made of PTFE, such as model LTC-800-PTFE. The liquid level is detected by the hydrostatic principle. The PTFE probe is in direct contact with the etching solution and has extremely strong corrosion resistance.

[0042] In addition, a drain pipe 9 is installed on the bottom side of the water tank 2. One end of the drain pipe 9 is connected to the return cavity 21, and the other end extends outside the water tank 2. A drain valve 91 is installed on the drain pipe 9. By controlling the opening and closing of the drain valve 91, the etching solution in the water tank 2 can be drained, which facilitates the maintenance and cleaning of the equipment. Multiple reinforcing ribs 22 are fixedly connected to the side of the water tank 2. These reinforcing ribs 22 are evenly distributed and connected to the water tank 2 by welding, which can effectively enhance the structural strength of the water tank 2 and prevent the water tank 2 from deforming due to long-term storage of etching solution.

[0043] The working process of this equipment is as follows:

[0044] Etching solution recirculation: The used ferric chloride etching solution continuously flows into the recirculation chamber 21 of the water tank 2 through the return water pipe 4.

[0045] Liquid level monitoring: The first liquid level sensor 81 and the second liquid level sensor 82 monitor the level of the etching solution in the reflux chamber 21 in real time and transmit the liquid level signal to the electrical control box 3.

[0046] Normal operating condition: When the etching solution level is between the first level sensor 81 and the second level sensor 82, the electrical control box 3 controls the first diversion pump 53 and the second diversion pump 63 to start, and at the same time opens the first diversion valve 52 and the second diversion valve 62. The etching solution enters the outlet pipe 7 through the first diversion pipe 51 and the second diversion pipe 61 and is transported to the subsequent treatment or reuse stage.

[0047] High-level warning status: When the etching solution level rises to the position of the second level sensor 82, the second level sensor 82 transmits a signal to the electrical control box 3. The electrical control box 3 immediately issues a control command: closes the electric valve 41 of the return water pipe 4 to stop the continued flow of etching solution; simultaneously controls the operation of the first diversion pump 53 and the second diversion pump 63 to accelerate the discharge speed of the etching solution. In addition, the electrical control box 3 controls the alarm 83 to issue an audible and visual alarm to remind the operator to handle the situation promptly.

[0048] Low level indication status: When the etching solution level drops to the position of the first level sensor 81, the first level sensor 81 transmits a signal to the electrical control box 3. The electrical control box 3 can indicate to the operator that the etching solution level is low, so as to make timely arrangements for the return or replenishment of the etching solution.

[0049] Maintenance and Drainage: When the equipment needs maintenance or cleaning, the operator can open the drain valve 91 and drain the etching solution in the water tank 2 through the drain pipe 9.

[0050] The ferric chloride etching solution regeneration and recycling equipment provided in this application, by setting a first liquid level sensor 81 (low level sensor) and a second liquid level sensor 82 (high level sensor), can monitor the liquid level of the etching solution in the water tank 2 in real time. When the liquid level reaches the position of the second liquid level sensor 82, the electrical control box 3 can immediately control the relevant mechanism to stop the backflow of the etching solution or start the diversion, and at the same time trigger the alarm 83 to remind the operator, which fundamentally avoids the overflow of the etching solution and improves the recovery of the etching solution.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
