[0002] When peeling off the film on a printed circuit board, the remaining photosensitive film on the surface of the circuit board is usually removed by a stripping solution. After the photosensitive film is removed, a large amount of membrane residue will be present in the wastewater generated by mixing the stripping solution with water. Existing filtration and collection devices can filter the membrane residue in the wastewater and collect the filtered membrane residue.

[0003] However, in existing devices, some wastewater still remains in the filtered membrane sludge, resulting in a heavier overall weight and increasing the load on subsequent transport vehicles. Furthermore, this wastewater is prone to leakage during transport due to compression or other factors, potentially causing leaks. Therefore, this application proposes a printed circuit board membrane sludge filtration and collection device that can flatten the filtered membrane sludge, accelerate its drying process, and allow air to carry away the wastewater mixed in with the sludge. Utility Model Content

[0004] The purpose of this utility model is to provide a printed circuit board membrane sludge filtration and collection device to solve the problem that, when the existing device mentioned in the background art is used, the filtered membrane sludge still contains some wastewater, which results in the overall weight of the membrane sludge being heavy, increasing the load on the subsequent processing and transportation vehicle, and the wastewater is prone to leaking out of the vehicle during transportation due to factors such as compression, which can easily cause wastewater leakage accidents.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a printed circuit board film residue filtration and collection device, including a storage box, a conveying mechanism is provided on the top of the storage box, and a settling tank is provided on one side of the storage box.

[0019] Beneficial effects:

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] like Figures 1-4 As shown in the figure, the printed circuit board film residue filtration and collection device provided by this utility model includes a storage box 1, a conveying mechanism 2 is provided on the top of the storage box 1, and a settling tank 3 is provided on one side of the storage box 1. The conveying mechanism 2 includes a conveying housing 201, a conveying shaft 202, a conveying blade 203, a driving device 204, an intercepting plate 206, and a feed pipe 207.

[0029] Specifically, the conveying housing 201 is configured as a cylindrical shape with an opening at one end, and the conveying housing 201 is inclined. The height of the side of the conveying housing 201 closer to the settling tank 3 is higher than the height of the side farther away from the settling tank 3. The conveying shaft 202 is inserted into the conveying housing 201, and the conveying shaft 202 is equipped with spirally distributed conveying blades 203. The lower end face of the conveying blades 203 abuts against the bottom end of the inner wall of the conveying housing 201. A fan-shaped groove is provided inside the conveying housing 201, and the intercepting plate 206 is inserted into the fan-shaped groove. The intercepting plate 206 is provided with several through holes, and the through holes on the intercepting plate 206 are arranged at equal intervals.

[0030] More specifically, the interceptor plate 206 is set to a circular shape equal to that of the conveyor housing 201, the through hole connects to the storage box 1, the feed pipe 207 is inserted into the conveyor housing 201, the drive device 204 is connected to the conveyor shaft 202, the drive device 204 can be a motor, and the output shaft of the motor can be connected to the conveyor shaft 202 through a coupling.

[0031] When peeling off the film from a printed circuit board, a stripping agent is used to separate the film from the board. The stripping agent is then mixed with water, and the resulting mixture is fed into the conveying housing 201 via the feed pipe 207. The conveying housing 201 is tilted upwards. After the mixed wastewater enters the conveying housing 201, [further details are needed]. Figure 2 Wastewater will preferentially accumulate on the side of the conveying housing 201 away from the opening. The wastewater enters the inside of the collection box 1 through the through hole, while the membrane sludge will remain inside the conveying housing 201 under the interception of the interception plate 206.

[0032] When the drive device 204 is started, it can drive the conveyor shaft 202 and the conveyor blades 203 to rotate, pushing the membrane sludge inside the conveyor housing 201 upwards, thereby separating the membrane sludge from the wastewater. The membrane sludge is pushed to the opening of the conveyor housing 201 and falls from the opening into the settling tank 3.

[0033] It should be noted that the conveying mechanism 2 is equipped with a drive box 205 and a support frame 208. The drive device 204 is retracted into the drive box 205, and the drive box 205 is installed on the storage box 1. The support frame 208 is located at the opening of the conveying housing 201, and the support frame 208 occupies the upper semi-circular area of ​​the opening, so it will not obstruct the movement of the membrane residue.

[0034] In order to allow the membrane residue to dry quickly, a water control plate 4 is installed inside the settling tank 3. There is a gap between the water control plate 4 and the bottom of the inner wall of the settling tank 3. The gap is used to store the wastewater after filtration. A drain pipe 9 is installed on the settling tank 3. The drain pipe 9 is located below the water control plate 4.

[0035] In order to spread out the membrane residue and prevent it from clumping together, thereby accelerating its drying speed, a smoothing shaft 5 is provided inside the settling tank 3. A transmission part 501 is provided on the smoothing shaft 5, and a smoothing component 6 is provided at the transmission part 501. The smoothing component 6 and the transmission part 501 can only slide relative to each other up and down. The two can move relative to each other up and down. At the same time, when the smoothing shaft 5 rotates, the smoothing component 6 can rotate synchronously.

[0036] In order to adjust the height of the smoothing part 6, a height adjustment unit 7 is provided at the smoothing shaft 5 and the smoothing part 6. The height adjustment unit 7 is used to adjust the height of the smoothing part 6 on the smoothing shaft 5.

[0037] Specifically, the height adjustment unit 7 includes an upper support 701, an adjusting rod 702, an adjusting tube 703, and a lower support 704. The upper support 701 is mounted on the smoothing shaft 5 and has an adjusting seat. The adjusting rod 702 is movably connected to the adjusting seat, and the adjusting rod 702 is threadedly connected to the adjusting tube 703. The adjusting tube 703 is movably connected to the lower support 704, which is mounted on the smoothing component 6. The smoothing component 6 contains two smoothing plates, and there are two height adjustment units 7. The two height adjustment units 7 are connected to the two smoothing plates respectively. The height adjustment unit 7 can also be an electric telescopic rod.

[0038] In order to drive the smoothing shaft 5 to rotate, a transmission unit 10 is also included. The transmission unit 10 is used to drive the smoothing shaft 5 to rotate. The transmission unit 10 includes two bevel gears, one of which is mounted on the smoothing shaft 5 and the other is mounted on the conveyor shaft 202. The two bevel gears are connected by meshing.

[0039] After the membrane residue falls onto the water control plate 4 in the settling tank 3, the transmission unit 10 drives the smoothing shaft 5 to rotate, which in turn causes the smoothing component 6 to rotate. The smoothing component 6 pushes the membrane residue accumulated on the water control plate 4 to move, allowing the membrane residue to be evenly distributed inside the settling tank 3, enabling the membrane residue to dry faster and facilitating subsequent unified processing. Furthermore, the transmission unit 10 transmits power from the conveyor shaft 202 to the smoothing shaft 5 through the meshing of bevel gears, achieving synchronous rotation of the conveyor shaft 202 and the smoothing shaft 5. This allows the separation and smoothing of the membrane residue to be carried out simultaneously within the conveyor housing 201 and the settling tank 3. The synchronous rotation of the conveyor shaft 202 and the smoothing shaft 5 simplifies operation, reduces the number of motors required, and lowers the cost of the equipment.

[0040] The top of the settling tank 3 is provided with a top plate 8, and the smoothing shaft 5 is movably connected to the top plate 8.

[0041] In summary, this utility model embodiment provides a printed circuit board membrane sludge filtration and collection device. Wastewater enters the inside of the collection box 1 through the through hole, while the membrane sludge is intercepted by the interception plate 206 and remains inside the conveying housing 201.

[0042] When the drive device 204 is started, it can drive the conveyor shaft 202 and the conveyor blades 203 to rotate, pushing the membrane sludge inside the conveyor housing 201 upwards, thereby separating the membrane sludge from the wastewater. The membrane sludge is pushed to the opening of the conveyor housing 201 and falls from the opening into the settling tank 3.

[0043] After the membrane residue falls onto the water control plate 4 in the settling tank 3, the transmission unit 10 can drive the smoothing shaft 5 to rotate, which in turn causes the smoothing component 6 to rotate. The smoothing component 6 can push the membrane residue accumulated on the water control plate 4 to move, so that the membrane residue is evenly distributed inside the settling tank 3, which can make the membrane residue dry faster and facilitate the unified treatment of the membrane residue in the future.

[0044] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
