Description

Technical Field

[0001] This utility model relates to the field of printed circuit board manufacturing equipment technology, and in particular to a device for collecting desoldering water filtrate. Background Technology

[0002] In the electroplating process of printed circuit boards, the tin layer serves as a crucial anti-etch layer to protect the copper patterns of the circuitry. After the etching process is completed, a desoldering solution (whose main components include nitric acid and ferric nitrate) is used to efficiently remove the tin layer, exposing the precisely designed copper circuitry and ensuring the accuracy of subsequent soldering and component mounting.

[0003] Currently, the mainstream treatment method for PCB manufacturers of solder stripping waste liquid is to add a precipitant to precipitate the tin ions in the waste liquid, resulting in a tin sludge mixture. This tin sludge is then filtered out and recycled using a filter press. The filtrate obtained from the filtration process is collected and repurposed for use in the solder stripping system. However, during this filtration process, the filtrate from the initial filtration stage often appears very turbid (called turbid liquid) due to the presence of incompletely separated fine tin sludge. If this turbid liquid is mixed with the later clear filtrate (called clear liquid) for collection, the overall quality of the filtrate in the collection tank will decline, containing suspended solids. This directly affects the chemical stability and process effectiveness when reused in the solder stripping system, potentially negatively impacting the quality of the printed circuit boards.

[0004] Therefore, there is an urgent need for a device that can distinguish and collect filtrates from different stages of pressure filtration in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a filtrate collection device for tin stripping water. This device can effectively distinguish and collect the turbid liquid generated in the early stage of pressure filtration and the clear liquid generated in the later stage, thereby improving the quality of the filtrate and overcoming the shortcomings of the prior art.

[0006] To achieve this objective, the present invention adopts the following technical solution: A tin stripping water filtrate collection device includes a cylinder, a partition plate, a three-way valve, a first manual valve, and a second manual valve. The partition plate is located inside the cylinder and is used to divide the interior of the cylinder into an independent turbid liquid collection chamber and a clear liquid collection chamber. The top of the cylinder is provided with a turbid liquid observation port and a clear liquid observation port. The turbid liquid observation port is located above the turbid liquid collection chamber, and the clear liquid observation port is located above the clear liquid collection chamber. The cylinder body has a turbid liquid inlet and a clear liquid inlet on its side wall. The turbid liquid inlet is located below the turbid liquid observation port and is connected to the turbid liquid collection chamber. The clear liquid inlet is located below the clear liquid observation port and is connected to the clear liquid collection chamber. The three-way valve is provided with a first interface, a second interface, and a third interface that are interconnected; the first interface is used to connect to the filtrate outlet of the filter press, the second interface is connected to the turbid liquid inlet, and the third interface is connected to the clear liquid inlet.

[0007] Furthermore, it also includes a transparent tube, through which the first interface is connected to the filtrate outlet of the filter press.

Both the first solenoid valve and the second solenoid valve are electrically connected to the turbidimeter.

[0009] Furthermore, the volume ratio of the turbid liquid collection chamber to the clear liquid collection chamber is 1:(1.5~2).

[0010] Furthermore, it also includes a transparent turbid liquid sealing assembly and a transparent clear liquid sealing assembly; Both the turbid liquid observation port and the clear liquid observation port have annular support platforms that protrude inward from their edges. The transparent turbid liquid sealing assembly is installed on the top of the support platform of the turbid liquid observation port, and the transparent turbid liquid sealing assembly is used to open and close the turbid liquid observation port; The transparent liquid sealing assembly is placed on top of the support platform of the liquid observation port, and is used to open and close the liquid observation port.

[0011] Furthermore, the top of the cylinder body is provided with a turbid liquid limiting component and a clear liquid limiting component protruding upwards; both the turbid liquid limiting component and the clear liquid limiting component are annular rims, and the height of the front baffle of the rim is less than the height of the rear baffle of the rim. The turbid liquid limiting component is located at the top of the turbid liquid observation port. The cross-sectional shape of the turbid liquid limiting component matches the cross-sectional shape of the transparent turbid liquid sealing assembly, and the transparent turbid liquid sealing assembly is detachably installed inside the turbid liquid limiting component. The clear liquid limiting component is located at the top of the clear liquid observation port. The cross-sectional shape of the clear liquid limiting component matches the cross-sectional shape of the transparent clear liquid sealing assembly, and the transparent clear liquid sealing assembly is detachably installed inside the clear liquid limiting component.

[0012] Furthermore, both the transparent turbid liquid sealing assembly and the transparent clear liquid sealing assembly include a tempered glass cover and a locking mechanism; The tempered glass cover is placed on top of the support platform, and the tempered glass cover is used to open and close the turbid liquid observation port and the clear liquid observation port; The locking element is rotatably mounted on the tempered glass cover, and the end edge of the locking element is provided with a locking tongue. Both the turbid liquid limiting member and the clear liquid limiting member have locking tongue grooves on their inner sidewalls.

[0016] The technical solution provided by this utility model can include the following beneficial effects: 1. The partition plate is located inside the cylinder and divides the interior of the cylinder into independent turbid liquid collection chamber and clear liquid collection chamber. The turbid liquid collection chamber is used to collect the turbid liquid generated in the early stage of filtration, and the clear liquid collection chamber is used to collect the clear liquid generated in the later stage. This device separates and collects the filtrate from different stages of filtration, ensuring the quality of the filtrate and solving the technical problem of filtrate quality degradation in the prior art.

[0017] 2. The top of the cylinder is equipped with a turbid liquid observation port and a clear liquid observation port. Since the turbid liquid inlet is located below the turbid liquid observation port, the operator can directly monitor the turbidity of the filtrate flowing from the turbid liquid inlet into the turbid liquid collection chamber through the turbid liquid observation port. If the filtrate flowing from the turbid liquid inlet into the turbid liquid collection chamber is observed to be relatively turbid, the filtrate continues to be discharged into the turbid liquid collection chamber; conversely, if the filtrate is relatively clear, it is discharged into the clear liquid collection chamber through the clear liquid inlet. Similarly, the clear liquid inlet is located below the clear liquid observation port. If the operator observes that the filtrate flowing from the clear liquid inlet into the clear liquid collection chamber is relatively clear, the filtrate continues to be discharged into the clear liquid collection chamber; conversely, if the filtrate is relatively clear, it is discharged into the turbid liquid collection chamber. In other words, this application, through the coordinated use of the turbid liquid observation port, the clear liquid observation port, the turbid liquid inlet, and the clear liquid inlet, facilitates the determination of when to discharge the filtrate from the filter press into the turbid liquid collection chamber or the clear liquid collection chamber.

Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] This technical solution provides a filtrate collection device for detinning water, including a cylinder 1, a partition plate 2, a three-way valve, a first manual valve and a second manual valve. The partition plate 2 is located inside the cylinder 1 and is used to divide the inside of the cylinder 1 into two independent turbid liquid collection chambers 5 and clear liquid collection chambers 6. The top of the cylinder 1 is provided with a turbid liquid observation port 7 and a clear liquid observation port 8. The turbid liquid observation port 7 is located above the turbid liquid collection chamber 5, and the clear liquid observation port 8 is located above the clear liquid collection chamber 6. The cylinder body 1 has a turbid liquid inlet 11 and a clear liquid inlet 12 on its side wall. The turbid liquid inlet 11 is located below the turbid liquid observation port 7 and is connected to the turbid liquid collection chamber 5. The clear liquid inlet 11 is located below the clear liquid observation port 8 and is connected to the clear liquid collection chamber 6. The three-way valve is provided with a first interface, a second interface and a third interface that are interconnected; the first interface is used to connect to the filtrate outlet of the filter press, the second interface is connected to the turbid liquid inlet 11, and the third interface is connected to the clear liquid inlet 12. A first manual valve for opening and closing the second interface is provided between the second interface and the turbid liquid inlet 11, and a second manual valve for opening and closing the third interface is provided between the third interface and the clear liquid inlet 12.

[0027] To address the technical problem of declining quality of collected filtrate in existing technologies, this technical solution proposes a tin stripping water filtrate collection device, such as... Figure 1-6As shown, the device includes a cylinder 1, a partition plate 2, a transparent turbid liquid sealing assembly 3, a transparent clear liquid sealing assembly 4, a filter press, and a three-way valve. The partition plate 2 is located inside the cylinder 1 and divides the interior of the cylinder 1 into two independent turbid liquid collection chambers 5 and clear liquid collection chambers 6. The turbid liquid collection chamber 5 is used to collect the turbid liquid generated in the early stage of filtration, and the clear liquid collection chamber 6 is used to collect the clear liquid generated in the later stage. This device separates and collects the filtrate from different stages of filtration, ensuring the quality of the filtrate and solving the technical problem of declining filtrate quality in the prior art.

[0028] Furthermore, the top of the cylinder 1 is provided with a turbid liquid observation port 7 and a clear liquid observation port 8. Since the turbid liquid inlet 11 is located below the turbid liquid observation port 7, the operator can directly monitor the turbidity of the filtrate flowing from the turbid liquid inlet 11 to the turbid liquid collection chamber 5 through the turbid liquid observation port 7. If the filtrate flowing from the turbid liquid inlet 11 to the turbid liquid collection chamber 5 is observed to be relatively turbid through the turbid liquid observation port 7, the filtrate continues to be discharged into the turbid liquid collection chamber 5. Otherwise, the filtrate is discharged into the clear liquid collection chamber 6 through the clear liquid inlet 12. Similarly, the clear liquid inlet 11 is located below the clear liquid observation port 8. If the operator observes that the filtrate flowing from the clear liquid inlet 12 to the clear liquid collection chamber 6 is relatively clear through the clear liquid observation port 8, the filtrate continues to be discharged into the clear liquid collection chamber 6. Otherwise, the filtrate is discharged into the turbid liquid collection chamber 5. That is, the present application uses the turbid liquid observation port 7, the clear liquid observation port 8, the turbid liquid inlet port 11 and the clear liquid inlet port 12 to cooperate with each other, which is helpful to determine when to discharge the filtrate in the filter press into the turbid liquid collection chamber 5 or the clear liquid collection chamber 6.

[0029] Furthermore, the three-way valve (not shown in the figure) is provided with a first interface, a second interface, and a third interface; the first interface is used to connect to the filtrate outlet of the filter press, the second interface is connected to the turbid liquid inlet 11, and the third interface is connected to the clear liquid inlet 12; a first manual valve for opening and closing the second interface is provided between the second interface and the turbid liquid inlet 11, and a second manual valve for opening and closing the third interface is provided between the third interface and the clear liquid inlet 12. The working principle of this technical solution is as follows: when the filtrate in the filter press is initially discharged, the first manual valve is opened and the second manual valve is closed, so that the turbid filtrate in the filter press enters the turbid liquid collection chamber 5 through the turbid liquid inlet 11. Simultaneously, the operator observes the turbidity of the filtrate flowing from the turbid liquid inlet 11 to the turbid liquid collection chamber 5 through the turbid liquid observation port 7. If the filtrate flowing from the turbid liquid inlet 11 to the turbid liquid collection chamber 5 is relatively clear, the first manual valve is closed and the second manual valve is opened, allowing the clear filtrate (clarified liquid) to enter the clear liquid collection chamber 6 through the clear liquid inlet 12 for collection. Similarly, during the filtrate discharge process in the filter press, if the operator observes through the clear liquid observation port 8 that the filtrate flowing from the clear liquid inlet 12 to the clear liquid collection chamber 6 is relatively turbid, the first manual valve is opened and the second manual valve is closed, allowing the turbid filtrate in the filter press to enter the turbid liquid collection chamber 5 through the turbid liquid inlet 11. Repeating the above steps allows for the separate collection of filtrates from different filtration stages.

[0030] Preferably, the bottom of the cylinder 1 is provided with a turbid liquid outlet 13 and a clear liquid outlet 14. The turbid liquid outlet 13 is connected to the turbid liquid collection chamber 5, and the clear liquid outlet 14 is connected to the clear liquid collection chamber 6.

[0031] By setting up a turbid liquid outlet 13 and a clear liquid outlet 14, when the turbid liquid in the turbid liquid collection chamber 5 needs to be discharged, the turbid liquid outlet 13 can be opened to discharge the turbid liquid; at the same time, when the clear liquid in the clear liquid collection chamber 6 needs to be discharged, the clear liquid outlet 14 can be opened to discharge the clear liquid.

[0032] Preferably, it also includes reinforcing ribs 9, and the number of reinforcing ribs 9 is provided in multiples, with the multiple reinforcing ribs 9 protruding from the outer wall and bottom of the cylinder body 1.

[0033] By setting multiple reinforcing ribs 9, the strength of the cylinder body 1 is enhanced, and its durability is improved.

[0034] To further explain, it also includes a transparent tube, through which the first interface is connected to the filtrate outlet of the filter press.

[0035] By setting a transparent tube (not shown in the figure), the turbidity of the filtrate in the filter press can be observed through the transparent tube. If the filtrate in the filter press is relatively turbid, the first manual valve is opened and the second manual valve is closed, so that the turbid filtrate in the filter press enters the turbid liquid collection chamber 5 through the turbid liquid inlet 11. If the filtrate in the filter press is relatively clear, the first manual valve is closed and the second manual valve is opened, so that the clear filtrate filtered out enters the clear liquid collection chamber 6 through the clear liquid inlet 12, which further facilitates the differentiation and collection of filtrates from different stages of filtration.

[0036] Further explanation: It also includes a turbidimeter, which is installed in the transparent tube and is used to measure the turbidity of the filtrate in the filter press; A first solenoid valve for opening and closing the second interface is provided between the second interface and the turbid liquid inlet 11. The first solenoid valve is connected in series with the first manual valve. A second solenoid valve for opening and closing the third interface is provided between the third interface and the clear liquid inlet 12. The second solenoid valve is connected in series with the second manual valve. Both the first solenoid valve and the second solenoid valve are electrically connected to the turbidimeter.

[0037] In some embodiments of this technical solution, a turbidimeter (not shown in the figure) is installed on a transparent tube, and a turbidimeter threshold is set on the turbidimeter. When the turbidimeter measures that the turbidity of the filtrate in the filter press is greater than or equal to the turbidimeter threshold, the first solenoid valve (not shown in the figure) is opened and the second solenoid valve (not shown in the figure) is closed, allowing the filtrate in the filter press to enter the turbid liquid collection chamber 5 through the turbid liquid inlet 11. When the turbidimeter measures that the turbidity of the filtrate in the filter press is less than the turbidimeter threshold, the first solenoid valve is closed and the second solenoid valve is opened, allowing the filtrate in the filter press to enter the clear liquid collection chamber 6 through the clear liquid inlet 12. This embodiment, by integrating the turbidimeter, the first solenoid valve, and the second solenoid valve, achieves fully automated switching between clear and turbid liquids without manual intervention, making the judgment more accurate and reliable, and further improving production efficiency and the quality stability of the collected liquid.

[0038] It should be noted that the turbidimeter is electrically connected to the first and second solenoid valves in the following way: the signal output terminal of the turbidimeter is connected to the analog input module of the PLC. The PLC receives the measurement signal from the turbidimeter in real time. When the signal value is greater than or equal to the turbidity threshold, the PLC controls the opening and closing of the first solenoid valve and the closing of the second solenoid valve, so that the filtrate enters the turbid liquid collection chamber 5. When the signal value is continuously lower than the turbidity threshold, the PLC controls the closing of the first solenoid valve and the opening of the second solenoid valve, so that the filtrate enters the clear liquid collection chamber 6, thereby realizing the automatic switching of the filtrate collection channel.

[0039] To further explain, the volume ratio of the turbid liquid collection chamber 5 to the clear liquid collection chamber 6 is 1:(1.5~2).

[0040] Since the amount of turbid filtrate initially generated by the filter press during operation is relatively small, while the amount of clear filtrate is relatively large, this technical solution limits the volume of the clear filtrate collection chamber 6 to be larger than the volume of the turbid filtrate collection chamber 5, facilitating the recovery of both turbid and clear filtrates.

[0041] Further explanation: It also includes a transparent turbid liquid sealing assembly 3 and a transparent clear liquid sealing assembly 4; Both the turbid liquid observation port 7 and the clear liquid observation port 8 are provided with annular support platforms 71 that protrude inward from their edges. The transparent turbid liquid sealing assembly 3 is placed on top of the support platform 71 of the turbid liquid observation port 7, and the transparent turbid liquid sealing assembly 3 is used to open and close the turbid liquid observation port 7. The transparent liquid sealing assembly 4 is placed on top of the support platform 71 of the liquid observation port 8, and the transparent liquid sealing assembly 4 is used to open and close the liquid observation port 8.

[0042] This technical solution, by setting up a transparent turbid liquid sealing component 3 and a transparent clear liquid sealing component 4, not only allows for convenient observation of the turbid liquid in the turbid liquid collection chamber 5 and the clear liquid in the clear liquid collection chamber 6 respectively, but also effectively seals the turbid liquid collection chamber 5 and the clear liquid collection chamber 6 respectively, preventing the volatile odor in the desoldering solution (which originates from the turbid liquid and the clear liquid, and the desoldering solution is usually an acidic liquid) from spreading into the working environment, protecting the health of employees, and also meeting environmental protection requirements.

[0043] To further explain, the top of the cylinder body 1 is provided with a turbid liquid limiting member 15 and a clear liquid limiting member 16 protruding upwards; both the turbid liquid limiting member 15 and the clear liquid limiting member 16 are annular rims, and the height of the front baffle 152 of the rim is less than the height of the rear baffle 153 of the rim. The turbid liquid limiting member 15 is located at the top of the turbid liquid observation port 7. The cross-sectional shape of the turbid liquid limiting member 15 matches the cross-sectional shape of the transparent turbid liquid sealing assembly 3, and the transparent turbid liquid sealing assembly 3 is detachably installed inside the turbid liquid limiting member 15. The clear liquid limiting member 16 is located at the top of the clear liquid observation port 8. The cross-sectional shape of the clear liquid limiting member 16 matches the cross-sectional shape of the transparent clear liquid sealing assembly 4, and the transparent clear liquid sealing assembly 4 is detachably installed inside the clear liquid limiting member 16.

[0044] By setting up a turbid liquid limiting component 15 and a clear liquid limiting component 16, the position of the transparent turbid liquid sealing assembly 3 is limited by the turbid liquid limiting component 15, and the position of the transparent clear liquid sealing assembly 4 is limited by the clear liquid limiting component 16, so as to prevent the transparent turbid liquid sealing assembly 3 and the transparent clear liquid sealing assembly 4 from moving, thereby ensuring the sealing effect of both.

[0045] Furthermore, both the turbid liquid limiting member 15 and the clear liquid limiting member 16 are annular rims, and the height of the front baffle 152 of the rim is less than the height of the rear baffle 153 of the rim. This allows the bottom plane of the rim, the front baffle 152, and the rear baffle 153 to jointly define an inclined guide surface, thereby facilitating the placement and removal of the transparent turbid liquid sealing assembly 3 and the transparent clear liquid sealing assembly 4, and improving operational convenience. It should be noted that the front baffle 152 is located in the front of the cylinder body 1, and the rear baffle 153 is located in the rear of the cylinder body.

[0046] To further explain, both the transparent turbid liquid sealing assembly 3 and the transparent clear liquid sealing assembly 4 include a tempered glass cover 31 and a locking element 32; The tempered glass cover 31 is placed on top of the support platform 71, and the tempered glass cover 31 is used to open and close the turbid liquid observation port 7 and the clear liquid observation port 8. The locking element 32 is horizontally rotatable and mounted on the tempered glass cover 31. The end edge of the locking element 32 is provided with a locking tongue 3221. Both the turbid liquid limiting member 15 and the clear liquid limiting member 16 have locking tongue grooves 151 on their inner sidewalls. The horizontal rotation of the locking member 32 causes the locking tongue part 3221 to engage or disengage from the locking tongue groove 151.

[0047] By setting up a tempered glass cover 31, a locking fastener 32, and a locking tongue groove 151, the operator only needs to rotate the locking fastener 32 to make the locking tongue 3221 engage or disengage from the locking tongue groove 15, thereby locking or disengaging the tempered glass cover 31 from the cylinder body 1, making the operation convenient and efficient.

[0048] To further explain, the locking element 32 includes a relatively stationary rotating rod 321, a locking block 322, and a mounting block 323; The mounting block 323 is located at the bottom of the tempered glass cover 31, and the mounting block 323 is located on one side of the support platform 71; The end of the rotating rod 321 passes through the tempered glass cover 31 and is connected to the mounting block 323; The locking block 322 is located on the top of the tempered glass cover 31, and the locking block 322 is sleeved on the outside of the rotating rod 321, and the locking tongue 3221 is recessed inward at the end edge of the locking block 322.

[0049] This technical solution uses a rotating rod 321, a locking block 322, and a mounting block 323. The rotation of the rotating rod 321 drives the rotation of the locking block 322, thereby causing the locking tongue 3221 of the locking block 322 to engage or disengage from the locking tongue groove 151, thus achieving the locking and disengagement of the tempered glass cover 31. The structure is simple, and the locking and disengagement methods are simple and efficient.

[0050] In addition, the locking tongue 3221 is recessed inward at the end edge of the movable end of the locking block 322, which makes it easier for the locking block 322 to be engaged or disengaged from the locking tongue groove 151, thereby improving the efficiency of locking and disengaging.

[0051] To further explain, the locking element 32 also includes a rotating handle 324, which is sleeved on the outside of the rotating rod 321 and integrally formed on the top of the locking block 322.

[0052] In a preferred embodiment of this technical solution, by setting a rotating handle 324, the rotation of the rotating rod 321 is adjusted by the rotating handle 324, thereby realizing the rotation of the rotating rod 321, and thus realizing the switching between the state of the locking tongue 3221 being engaged or disengaged from the locking tongue groove 15.

[0053] To further explain, both the transparent turbid liquid sealing assembly 3 and the transparent clear liquid sealing assembly 4 include a glass cover handle 33, which is located at the top center of the tempered glass cover 31.

[0054] The addition of a handle 33 to the glass cover makes it easier to open the tempered glass cover 31.
