Description

Technical Field

[0001] This utility model relates to the field of chemical residue collection technology, and more specifically, to a chemical residue collection device for PCB production. Background Technology

[0002] With the continuous development of technology, people's demand for electronic products is also increasing. A large number of PCB boards are produced for people to use. During the production process of PCB boards, chemical solutions are needed to treat the surface. Therefore, chemical solution residue collection devices are needed to collect the residue to avoid polluting the environment. Existing chemical solution collection devices basically use a filter screen and filter cartridge for collection.

[0003] A search revealed, for example, a Chinese patent application with publication number CN216092451U, which discloses a chemical residue collection device for circuit board production. This device utilizes a limiting groove, an L-shaped groove, a movable mesh, pins, and an L-shaped rod. When a worker lifts the L-shaped rod, it moves upward within the L-shaped groove. Simultaneously, the L-shaped rod drives the movable mesh upward between two limiting grooves, causing several pins to insert into corresponding filter holes. This ensures that residue in the filter holes on the inclined plate is pushed out, clearing the filter holes and allowing the chemical residue on the inclined plate to effectively fall through the filter holes to the bottom of the collection chamber for collection. This allows for the efficient collection of large quantities of chemical residue. The device also includes a collection groove, a U-shaped tube, a discharge port, a threaded plug, and a permeation plate. The system consists of a push plate, a chute, a hydraulic cylinder, a sliding plate, and springs. The output shaft of the hydraulic cylinder pushes the push plate to move within the collection chamber. Simultaneously, the sliding plate is compressed by several springs, ensuring its bottom remains pressed against the inclined plate. The sliding plate moves towards the collection trough along with the push plate, ensuring that the residue on the inclined plate is pushed into the collection trough. Subsequently, the residue in the collection trough enters the U-shaped tube under gravity and falls onto the threaded plug. At this point, the chemical residue contained in the residue enters the collection chamber through the permeation plate, ensuring effective collection of the chemical residue. Then, personnel can rotate the threaded plug to remove it from the outlet, allowing the residue in the U-shaped tube to be discharged to the outside through the outlet, facilitating easy cleaning of the residue on the inclined plate.

[0004] However, the above solution can only filter the residue. As is well known, the chemical residues used in PCB production contain heavy metals, and the above solution is difficult to separate heavy metal substances, resulting in a limited effect. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a chemical residue collection device for PCB production, and the technical problem to be solved is: it is difficult to separate heavy metal substances.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chemical residue collection device for PCB manufacturing, comprising a collection tank:

[0007] The inner wall of the collection box is fixedly provided with a funnel platform, a drain pipe is connected to one side of the lower end of the collection box, and a sewage pipe passes through the lower end of the collection box;

[0008] The collection box is equipped with a filter plate installation device for filtering chemical residues inside the collection box.

[0009] The filter plate mounting device includes a mounting groove, which is opened in the inner wall of the collection box. A mounting frame is movably provided inside the mounting groove. A first filter screen and a filter element are fixedly provided on the inner wall of the mounting frame. The first filter screen is located at the upper end of the filter element.

[0010] The collection box is equipped with a reaction filtration device for separating heavy metals, which is used to filter out heavy metals from the chemical solution after the reaction.

[0011] In a preferred embodiment, a handle is fixedly provided on one side of the collection box, and two movable limiting blocks are hinged to one side of the collection box, the movable limiting blocks being located on one side of the mounting frame.

[0012] In a preferred embodiment, rubber strips are fixedly provided in the grooves at the upper and lower ends of the mounting frame, and the mounting frame is adapted to the mounting groove.

[0013] In a preferred embodiment, the reaction filtration device includes a receiving box, which is fixedly installed at the lower end of the funnel platform. A chemical reagent tube is connected to one side of the receiving box, which passes through one side of the collecting box and is connected to the output end of a reagent pump. The reagent pump draws the metal reactant into the receiving box.

[0014] In a preferred embodiment, the receiving box has grooves on both sides, a second filter screen is fixed inside the grooves, and the upper end of the drain pipe is connected to the lower end of the receiving box.

[0015] In a preferred embodiment, a movable frame is movably provided on the outer surface of the receiving box, and blocks are fixedly provided on both sides of the inner wall of the movable frame. The blocks are located inside the slide groove. Connecting ears are fixedly provided on both sides of the movable frame. Two electric push rods are fixedly provided at the lower end of the collecting box. The output end of the electric push rod passes through the lower end of the collecting box and is fixedly connected to the lower end of the connecting ear.

[0016] In a preferred embodiment, the lower end of the collection box is fixedly provided with a support foot, a controller is fixedly provided on one side of the collection box, the upper end of the collection box is connected to a feed pipe, the upper end of the feed pipe is threadedly connected to a sealing cap, and a booster pump is fixedly provided on the upper end of the collection box by a bracket, and the outlet of the booster pump is connected to the upper end of the collection box.

[0017] The present invention has the following advantages:

[0018] 1. This utility model uses an installation frame inserted into the installation groove. The rubber strips at the top and bottom of the installation frame can prevent leakage of chemical residue, allowing the chemical residue to pass through the first filter screen. The booster pump can pressurize the inside of the collection tank, thereby improving the filtration efficiency of the chemical residue. This allows the chemical residue to quickly pass through the first filter screen and be filtered by the filter element. When the first filter screen and filter element are clogged, the installation frame can be pulled out of the installation groove by rotating the two movable limit blocks and pulling the handle, thereby reducing unnecessary operations and making the installation of the first filter screen and filter element more convenient.

[0019] 2. This utility model uses a funnel platform to allow the filtered chemical solution residue to flow into a receiving tank. A metal reactant is then drawn in through a chemical reagent tube, mixing with the chemical solution residue to react and precipitate the heavy metals. Once the reaction time is reached, two electric push rods pull the movable frame, lowering the baffle from the chute. This allows the reacted chemical solution residue to be discharged through a drain pipe. The remaining heavy metal precipitate is discharged through a drain pipe, thus improving the utility model's practicality and enabling the separation of heavy metals from chemical solution residue.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] like Figure 1 and 2 As shown, this utility model provides a chemical residue collection device for PCB production, including a collection box 1: a funnel platform 10 is fixedly provided on the inner wall of the collection box 1, a drain pipe 9 is connected to one side of the lower end of the collection box 1, a sewage pipe 5 passes through the lower end of the collection box 1, a support foot 4 is fixedly provided at the lower end of the collection box 1, a controller 11 is fixedly provided on one side of the collection box 1, a feed pipe 6 is connected to the upper end of the collection box 1, a sealing cap 8 is threadedly connected to the upper end of the feed pipe 6, and a booster pump 7 is fixedly provided at the upper end of the collection box 1 by a bracket, and the outlet of the booster pump 7 is connected to the upper end of the collection box 1.

[0030] In order to simplify the operation steps and make it easier to install the first filter screen 24 and filter element 25, the inside of the collection box 1 is equipped with a filter plate mounting device 2 for filtering chemical residues, which is used to filter chemical residues inside the collection box 1.

[0031] like Figure 3As shown, the filter plate mounting device 2 includes a mounting groove 21, which is formed on the inner wall of the collection box 1. A mounting frame 22 is movably mounted inside the mounting groove 21. A first filter screen 24 and a filter element 25 are fixedly mounted on the inner wall of the mounting frame 22. The first filter screen 24 is located at the upper end of the filter element 25. A handle 23 is fixedly mounted on one side of the collection box 1. Two movable limiting blocks 27 are hinged to one side of the collection box 1, located on one side of the mounting frame 22. Rubber strips 26 are fixedly mounted in the grooves at both ends of the mounting frame 22. The mounting frame 22 is adapted to the mounting groove 21. The mounting frame 22 is inserted into the mounting groove 21, utilizing the mounting... The rubber strips 26 at the top and bottom of the frame 22 prevent leakage of chemical residue, allowing the chemical residue to pass through the first filter screen 24. The booster pump 7 pressurizes the inside of the collection tank 1, thereby improving the filtration efficiency of the chemical residue and enabling it to quickly pass through the first filter screen 24 and be filtered by the filter element 25. When the first filter screen 24 and the filter element 25 are clogged, the frame 22 can be pulled out of the mounting slot 21 by rotating the two movable limit blocks 27 and pulling the handle 23, thereby reducing unnecessary operations and making the installation of the first filter screen 24 and the filter element 25 more convenient.

[0032] Furthermore, in order to separate heavy metals from the chemical solution residue, the collection tank 1 is equipped with a reaction filter device 3 for separating heavy metals, which is used to filter out heavy metals in the chemical solution after the reaction.

[0033] like Figure 4 and 5 As shown, the reaction filtration device 3 includes a receiving box 31, which is fixedly installed at the lower end of the funnel platform 10. A chemical reagent tube 32 is connected to one side of the receiving box 31 and passes through one side of the collection box 1. Slide grooves 33 are provided on both sides of the receiving box 31. A second filter screen 38 is fixedly installed inside the slide grooves 33. The upper end of the drain pipe 5 is connected to the lower end of the receiving box 31. A movable frame 34 is movably installed on the outer surface of the receiving box 31. Blocks 35 are fixedly installed on both sides of the inner wall of the movable frame 34. The blocks 35 are located inside the slide grooves 33. Connecting ears 36 are fixedly installed on both sides of the movable frame 34. Two electric push rods 37 are fixedly installed at the lower end of the collection box 1. The electric push rods 37 output... The end of the electric push rod 37 is fixedly connected to the lower end of the connecting ear 36 through the bottom of the collection box 1. The filtered chemical residue flows into the receiving box 31 through the funnel platform 10. The metal reactant is drawn in by the chemical reagent tube 32 and mixed in with the chemical residue, causing the heavy metals to react and precipitate. When the reaction time is reached, the two electric push rods 37 pull the movable frame 34 to move the stop block 35 down from the slide 33, thereby draining the chemical residue after the reaction through the drain pipe 9. The remaining heavy metal precipitate is discharged through the drain pipe 5, thereby improving the practicality of this utility model and enabling the separation of heavy metals from chemical residue.

[0034] The working principle is as follows: When using this utility model, the residual liquid of chemical solution used in PCB production is poured into the feed pipe 6, and then the utility model is sealed with the sealing cap 8. The booster pump 7 is started, and the residual liquid of chemical solution is filtered by the first filter screen 24 and the filter element 25. When the first filter screen 24 and the filter element 25 are clogged, the first filter screen 24 and the filter element 25 can be quickly replaced and cleaned by the filter plate mounting device 2. After the residual liquid of chemical solution is filtered, the heavy metals are reacted and settled by the reaction filtration device 3, and the heavy metal precipitate is discharged through the drain pipe 5. The residual liquid of chemical solution after reaction is discharged from the drain pipe 9. Overall, the utility model is improved, the unnecessary operation of replacing the first filter screen 24 and the filter element 25 is reduced, and heavy metals in the waste liquid can be removed.

[0035] In addition, it is worth noting that the control process of electronic devices such as booster pump 7 and electric push rod 37 in this utility model is realized by controller 11. The control circuit and structure of controller 11 are mature existing technologies, so they will not be described in detail in this utility model.

[0036] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
