Description

Technical Field

[0001] This disclosure relates to the field of cleaning solution filtration and recovery technology, and in particular to a cleaning solution circulation filtration sedimentation and waste residue recovery device. Background Technology

[0002] Cleaning silver paste from substrates is a crucial process in photovoltaic manufacturing. Currently, there are some pressing issues regarding the treatment of the cleaning solution in this process.

[0003] Existing cleaning solution treatment methods, while involving some degree of recycling, have a low overall recycling rate. On one hand, insufficient filtration precision in the treatment devices makes it difficult to fully remove impurities from the cleaning solution, resulting in a solution that cannot meet the requirements for re-cleaning. This leads to a significant waste of potentially recyclable cleaning solution and increases production costs.

[0004] On the other hand, existing recycling technologies struggle to efficiently and thoroughly recover substances such as silver paste residue contained in the cleaning solution. Valuable components like silver in the residue cannot be fully extracted and utilized, resulting in resource waste. Furthermore, improper disposal of cleaning solutions containing residue can pollute the environment.

[0005] In addition, the existing processing equipment is lacking in automation, making it difficult to accurately control and adjust according to the actual situation of the cleaning solution, which further affects the recycling rate and treatment effect of the cleaning solution.

[0006] Therefore, there is an urgent need for a cleaning solution circulation filtration sedimentation and waste residue recycling device that can improve the recycling rate of cleaning solutions, achieve efficient waste residue recycling, and have a higher degree of automation, so as to meet the needs of the photovoltaic industry for efficient resource utilization and environmental protection.

[0034] Example

[0035] like Figure 1-3 As shown, this embodiment provides a cleaning solution circulation filtration sedimentation and waste residue recovery device, including a filtration sedimentation tank 100, including a first inlet 101, n (n≥1) filter sections are arranged sequentially from top to bottom at the output end of the first inlet 101, and a sedimentation section is arranged at the output end of the filter section. A bottom water storage section 5 is arranged at the bottom of the filtration sedimentation tank 100, and a first outlet 102 is opened in the bottom water storage section 5. The first outlet 102 is connected to a water pump 6 through a pipe; a cleaning water tank, including a second inlet 201 and a second outlet 202.

[0036] The first inlet 101 is connected to the second outlet 202, and the output end of the water pump 6 is connected to the second inlet 201, so that the filter sedimentation tank 100 and the cleaning water pool form a circulation.

[0037] In this application, the second outlet 202 of the cleaning tank 200 and the first inlet 101 of the filter sedimentation tank 100 are connected by a pipe. It should be noted that the first inlet 101 of the filter sedimentation tank 100 is located at the top of the filter sedimentation tank 100, so that the cleaning liquid of the cleaning tank 200 can flow downward under the action of gravity after entering the first inlet 101 through the pipe. Inside the filter sedimentation tank 100, below the first outlet 102, there are n (n≥1) filter sections arranged sequentially from top to bottom. After the cleaning liquid passes through the n filter sections in sequence, it enters the sedimentation section. After sedimentation in the sedimentation section, it is stored in the bottom water storage section 5 at the bottom and then pumped back to the cleaning tank 200 for recycling by the water pump 6.

[0038] In one embodiment of this application, there are two filtration units, including a first filtration unit and a second filtration unit, which are arranged sequentially from top to bottom. The cleaning solution is filtered by passing through the first filtration unit and the second filtration unit sequentially.

[0039] Specifically, the first filtration section includes a first filter housing 311 and a first filter screen 312, with the first filter screen 312 disposed at the bottom of the first filter housing 311. The second filtration section includes a second filter housing 321 and a second filter screen 322, with the second filter screen 322 disposed at the bottom of the second filter housing 321. A support member 7 is bolted to the inner side of the filtration sedimentation tank 100. The first filter housing 311 and the second filter housing 321 are detachably connected to the support member 7. The first filter housing 311 and the second filter housing 321 are directly mounted on top of the support member 7. When filter residue needs to be collected, the first filter housing 311 and the second filter housing 321 can be directly removed, and the filter residue on the filter screen can be cleaned out.

[0040] Specifically, the sedimentation section includes a sedimentation tank 41, with a sedimentation tank 42 at its upper part. A third filter screen 43 is provided on the side of the sedimentation tank 42 near the bottom water storage section 5. The water pump 6 is located inside the sedimentation tank 41, separating it from the bottom water storage section 5. The sedimentation tank 41 and the inner side of the filter sedimentation tank 100 are integrally formed or welded to each other. A sedimentation tank 42 is provided at the top of the sedimentation tank 41. The cleaning liquid after being filtered by the first and second filters flows into the sedimentation tank 42. After being filtered by the third filter screen 43, the cleaning liquid enters the bottom water storage section 5. The water pump 6 is located inside the sedimentation tank 41, separating it from the bottom water storage section 5, so that the water pump 6 is not affected by the liquid and its service life is improved.

[0041] Furthermore, the pore sizes of the first filter screen 312, the second filter screen 322, and the third filter screen 43 decrease sequentially. Through staged filtration using the first filter screen 312, the second filter screen 322, and the third filter screen 43, the filtration accuracy is improved, ensuring thorough filtration of the cleaning solution. After three layers of filtration, the cleaning solution enters the bottom water storage section 5 and is finally pumped back into the cleaning tank 200 by the water pump 6.

[0042] In one embodiment of this application, the cleaning water tank is equipped with a liquid level sensor 203, which is used to detect the liquid level in the cleaning water tank and control the operation of the water pump 6. The liquid level sensor 203 is used to monitor the liquid level in the cleaning water tank in real time. When the liquid level drops to a certain range, a signal is transmitted to the control system through a wire. The control system then instructs the water pump 6 to operate, which facilitates automated control and management and improves the operating efficiency and stability of the device.

[0043] In one embodiment of this application, at least one filter 300 is provided between the water pump 6 and the second inlet 201 to filter the liquid entering the cleaning tank 200. In this embodiment, two filters 300 are provided on each circulation pipe to ensure the cleanliness of the recovered cleaning solution.

[0044] In one embodiment of this application, the filter sedimentation tank 100 is hinged with a lid 103, which can be rotated to open or close the opening of the filter sedimentation tank 100. During operation, the lid 103 is closed to prevent internal liquid from splashing out or external dust from contaminating the internal cleaning fluid. When the waste residue on the filter screen settles to a certain extent, the lid 103 is opened to recycle the internal waste residue.

[0045] In one embodiment of this application, the number of the first inlet 101, the first outlet 102, the second inlet 201, the second outlet 202, and the water pump 6 are all two, forming two sets of circulation. The two sets of circulation pipes can improve the liquid circulation speed, and the two first inlets 101 are arranged side by side, so the position of the cleaning liquid entering the filter section is more uniform, thereby improving the filtration speed.

[0046] The working principle of this utility model is as follows: The cleaning liquid in the cleaning tank 200 is discharged through the second outlet 202 and enters the first inlet 101 of the filter sedimentation tank 100. After entering through the first inlet 101, it is filtered once through the first filter section and the second filter section, and then filtered a third time through the sedimentation section before entering the bottom water storage section 5. The first outlet 102 of the bottom water storage section 5 is connected to the water pump 6. The water pump 6 transports the filtered cleaning liquid back to the cleaning tank 200. During the transportation process, it is further filtered by the filter 300 to ensure the cleanliness of the cleaning liquid. In addition, this application provides a liquid level sensor 203 in the cleaning tank 200 to monitor the liquid level in the cleaning tank 200 in real time. When the liquid level drops to a certain range, a signal is transmitted to the control system through a wire. The control system instructs the water pump 6 to work, which facilitates automated control and management and improves the operating efficiency and stability of the device.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
