Description

Technical Field

[0001] This utility model relates to the field of waste liquid treatment, and in particular to a PCB etching waste liquid treatment device. Background Technology

[0002] PCB, or Printed Circuit Board, is a crucial electronic component in electronic products, serving as the support for electronic components and the carrier for electrical connections. Etching is a key process in PCB manufacturing, using an etching solution to remove unwanted copper foil from the copper-clad laminate, thus obtaining the designed circuitry. PCB etching wastewater is the industrial wastewater generated after the etching process, containing large amounts of copper ions, acid ions, and other additives. To achieve the harmless treatment of PCB etching wastewater and the recycling of resources such as copper, PCB etching wastewater treatment equipment is required.

[0003] In existing technologies, some PCB etching waste liquid treatment devices require workers to put the waste liquid and treatment agent into a mixing tank in a certain proportion, and then use the stirring component to fully mix the treatment agent and waste liquid in the tank to treat the waste liquid. However, after each waste liquid treatment is completed, workers need to manually add materials again, which not only increases the workload of workers, but also makes the manual material addition method inefficient. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a PCB etching waste liquid treatment device to solve the problem that some PCB etching waste liquid treatment devices mentioned in the background technology require workers to manually add materials again after each waste liquid treatment, which not only increases the workload of workers, but also makes the manual material addition method inefficient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PCB etching waste liquid treatment device, comprising:

[0006] Base;

A connecting rod is fixedly installed on the inner wall of the mixing tank. A float plate is provided at one end of the connecting rod. A first sealing component and a second sealing component are fixedly connected to the side of the float plate facing the connecting rod.

[0010] An adjustment assembly is located at the top of the mixing tank; the adjustment assembly includes a connecting pipe, a protective shell, and an adjustment disc; the connecting pipe and the first infusion tube, and the connecting pipe and the second infusion tube are slidably connected; the protective shell is fixedly connected to the top of the mixing tank, and a through hole is opened at the top of the protective shell; the adjustment disc is rotatably installed inside the protective shell, and the adjustment disc has several channels.

[0011] A stirring assembly is located at the top of the mixing tank, on one side of the adjusting assembly. The stirring assembly includes a stirring motor and a stirring rod. The stirring motor is fixedly installed at the top of the mixing tank, and the stirring rod is fixedly connected to the output end of the stirring motor.

[0012] Furthermore, the adjustment assembly also includes a slide rod, a return spring, a slide block, and a transmission rod; the slide rod is fixedly installed on the top of the mixing tank, the return spring is sleeved on the surface of the slide rod, the slide block is slidably connected to the surface of the slide rod located on one side of the return spring, the transmission rod is rotatably connected to both sides of the slide block, and the connecting pipe is rotatably connected to one end of the transmission rod.

[0013] Furthermore, the connecting rod also includes:

[0014] An extension rod is slidably connected inside a connecting rod. The extension rod is fixedly connected to the float plate. Both the extension rod and the connecting rod are rectangular structures.

[0015] Furthermore, the bottoms of both the first and second sealing components are cylindrical, and the tops of both are conical.

[0016] Furthermore, several of the channels are distributed in a circle around the center of the adjustment disc, and the vertical cross-section of the channels is T-shaped.

[0039] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0040] Please see Figures 1 to 3 This utility model provides a technical solution: a PCB etching waste liquid treatment device, comprising: a base 1, a waste liquid storage tank 2 fixedly installed on the base 1, and an infusion pipe 201 fixedly connected to the outside of the waste liquid storage tank 2. A treatment agent storage tank 3 is also fixedly installed on the base 1, and a first infusion pipe 301 is fixedly connected to the outside of the treatment agent storage tank 3. A mixing tank 4 is also fixedly installed on the base 1, and the mixing tank 4 is connected to the infusion pipe 201. A second infusion pipe 401 is fixedly connected to the top of the mixing tank 4. A connecting rod 402 is fixedly installed on the inner wall of the mixing tank 4, and a float plate 403 is provided at one end of the connecting rod 402. A first sealing component 404 and a second sealing component 405 are fixedly connected to the side of the float plate 403 facing the connecting rod 402.

[0041] An adjustment component 5 and a stirring component 6 are provided at the top of the mixing tank 4 on one side of the second infusion tube 401.

[0042] Please see Figures 3 to 5 The adjusting assembly 5 includes a slide rod 501, a return spring 502, a slide seat 503, a transmission rod 504, a connecting pipe 505, a protective shell 506, and an adjusting disc 507. The slide rod 501 is fixedly installed on the top of the mixing tank 4. The return spring 502 is installed on the surface of the slide rod 501. The slide seat 503 is slidably connected to the surface of the slide rod 501 and located on one side of the return spring 502. The transmission rod 504 is rotatably connected to both sides of the slide seat 503. The connecting pipe 505 is rotatably connected to one end of the transmission rod 504. The connecting pipe 505 is slidably connected to the first infusion tube 301 and to the second infusion tube 401. The protective shell 506 is fixedly installed on the top of the mixing tank 4. A through hole 5061 is opened at the top of the protective shell 506. The adjusting disc 507 is rotatably connected inside the protective shell 506 and has several channels 5071.

[0043] Pulling the slide block 503 causes it to slide along the surface of the slide rod 501 and compress the return spring 502, thereby driving the transmission rods 504 connected to both sides of the slide block 503 to rotate. This, in turn, causes the connecting pipes 505 connected to the other ends of the two transmission rods 504 to slide along the surfaces of the first infusion tube 301 and the second infusion tube 401, respectively. This allows the connecting pipes 505 to disengage from the channel 5071 on the surface of the adjusting plate 507. Then, while keeping the slide block 503 stationary, rotate the adjusting plate 507 so that it rotates within the protective shell 506 until the channel 5071 with the corresponding inner diameter is aligned with the first infusion tube 301 and the second infusion tube 401. Then, release the slide block 503, and the connecting pipe 505 will be inserted into the channel 5071 under the action of the return spring 502. This allows the ratio between waste liquid and treatment agent to be adjusted, making the device suitable for treating different types of waste liquid and enhancing its applicability.

[0044] Furthermore, several channels 5071 are distributed in a circle around the center of the adjusting disk 507, and the vertical cross-section of the channels 5071 is T-shaped.

[0045] The vertical cross-section of channel 5071 is T-shaped to ensure that there is sufficient space at both ends of channel 5071 for insertion of the connecting pipe 505.

[0046] Furthermore, an indicator plate 508 is fixedly connected to the top of the protective shell 506, and an indicator rod 509 is fixedly connected to the top of the adjustment disc 507.

[0047] Each scale of the indicator plate 508 corresponds to the inner diameter of each channel 5071. During the rotation of the adjustment plate 507, the indicator rod 509 will rotate together with the adjustment plate 507. By observing the positional relationship between the sharp side of the indicator rod 509 and the indicator plate 508, it is easy to know the inner diameter of the connecting pipe 505 that is directly opposite the first infusion tube 301 and the second infusion tube 401.

[0048] Preferably, a sealing gasket 510 is fixedly connected to one end of the connector 505.

[0049] The sealing gasket 510 can improve the sealing between the connecting pipe 505 and the channel 5071.

[0050] Optionally, the surface of the slide 503 is provided with anti-slip texture, and the anti-slip texture is integrally formed with the surface of the slide 503.

[0051] The anti-slip texture increases the friction between the hand and the slide block 503, thereby preventing the hand from slipping while pulling the slide block 503.

[0052] Please see Figure 2The stirring assembly 6 includes a stirring motor 601 and a stirring rod 602. The stirring motor 601 is fixedly installed on the top of the mixing tank 4, and the stirring rod 602 is fixedly connected to the output end of the stirring motor 601.

[0053] During the waste liquid treatment process, the stirring motor 601 will drive the stirring rod 602 to mix and stir the waste liquid and treatment agent located in the mixing tank 4, thereby improving the mixing effect of the waste liquid and treatment agent.

[0054] Preferably, the vertical cross-section of the stirring rod 602 is W-shaped, and the rod body of the stirring rod 602 is a one-piece molded structure.

[0055] The W-shaped vertical cross-section of the stirring rod 602 not only increases its contact area with the liquid in the mixing tank 4 and improves the uniformity of stirring, but also the multi-segment bends of the W shape can create more complex fluid disturbances during stirring, allowing the treatment agent and waste liquid to mix more thoroughly, further enhancing the treatment effect on the waste liquid.

[0056] Waste liquid and treatment agent are stored in waste liquid storage tank 2 and treatment agent storage tank 3, respectively. When treating waste liquid, the waste liquid will flow into mixing tank 4 through infusion pipe 201. The treatment agent will enter the mixing tank 4 through first infusion pipe 301, regulating component 5 and first infusion pipe 301. During this process, float plate 403 will move upward as the liquid level in mixing tank 4 rises. Connecting rod 402 will ensure that float plate 403 moves vertically upward. When there is too much waste liquid in mixing tank 4, float plate 403 will drive first sealing component 404 and second sealing component 405 to gradually seal infusion pipe 201 and second infusion pipe 401. This not only allows the feeding of waste liquid and treatment agent without manual monitoring and operation, which is beneficial to improving the treatment efficiency, but also allows the addition rate of waste liquid and treatment agent to be dynamically adjusted according to the remaining liquid in mixing tank 4.

[0057] Furthermore, an extension rod 4021 is slidably connected inside the connecting rod 402, and the extension rod 4021 is fixedly connected to the float 403. Both the extension rod 402 and the connecting rod 402 are rectangular.

[0058] During the addition of waste liquid and treatment agent, the extension rod 4021 will slide along the inner wall of the connecting rod 402, thereby ensuring that the float 403 always moves vertically upward.

[0059] Furthermore, the bottoms of both the first sealing element 404 and the second sealing element 405 are cylindrical, and the tops of both the first sealing element 404 and the second sealing element 405 are conical.

[0060] By setting the tops of the first sealing member 404 and the second sealing member 405 into a conical shape, the gap between the first sealing member 404 and the infusion pipe 201, and between the second sealing member 405 and the second infusion pipe 401, can be reduced when the liquid level rises, thereby reducing the flow rate of waste liquid and treatment agent. Similarly, when the liquid level drops, the flow rate of waste liquid or treatment agent will increase. In this way, the addition rate of waste liquid and treatment agent can be dynamically adjusted according to the liquid level in the mixing tank 4.

[0061] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
