Technical Field
[0001] This utility model relates to the field of slicing machine technology, and more specifically, to a drainage system and a wire cutting device having the same. Background Technology
[0002] Currently, after the photovoltaic silicon wafer slicing machine completes the cutting process, the waste cutting fluid (i.e., slurry) in the supply cylinder needs to be drained. Additionally, after the photovoltaic silicon wafer slicing machine has been used for a period of time, an alkaline solution is typically used to clean the inner wall of the supply cylinder to remove impurities.
[0003] In existing technologies, liquid drainage is typically achieved by manually turning valves to discharge slurry or alkaline solution outside the photovoltaic silicon wafer slicing machine. However, this manual drainage method not only increases the workload of workers but also makes it impossible to accurately determine whether the liquid in the supply tank is slurry or alkaline solution. Since alkaline solution is corrosive, incorrect judgment and accidental discharge can cause waste liquid pollution. Utility Model Content
[0004] The main objective of this invention is to provide a drainage system and a wire cutting device thereof, so as to solve the problems of increased labor intensity and waste liquid pollution caused by the drainage method of photovoltaic silicon wafer slicing machines in the prior art.
[0005] To achieve the above objectives, according to one aspect of the present invention, a drainage system is provided for draining liquid within a liquid supply structure. The drainage system includes: a first detection device for detecting the pH value of the liquid stored within the liquid supply structure; and a drainage assembly including a main drainage pipe and multiple branch drainage pipes, at least one branch drainage pipe for draining slurry and at least another branch drainage pipe for draining alkaline solution; wherein a first end of the main drainage pipe is connected to the liquid supply structure; when the detection value of the first detection device is less than or equal to a preset value, a second end of the main drainage pipe is connected to the branch drainage pipe for draining slurry; and when the detection value of the first detection device is greater than the preset value, the other end of the main drainage pipe is connected to the branch drainage pipe for draining alkaline solution.
[0006] Furthermore, the first detection device includes: a pH meter, at least a portion of which extends into the liquid supply structure; and a cover that covers the pH meter.
[0007] Furthermore, the drainage assembly also includes a first control valve, which is disposed on the drainage manifold to control the on / off state of the drainage manifold or to adjust the flow rate or velocity of the liquid medium in the drainage manifold.
[0008] Furthermore, the drainage assembly also includes: a pump body structure, which has an inlet and multiple outlets connected to the inlet. The inlet is connected to the second end of the main drainage pipe, and the multiple outlets are connected to multiple drainage branch pipes in a corresponding manner.
[0009] Furthermore, the multiple drainage branches include a first drainage branch and a second drainage branch, the first drainage branch being used to discharge slurry and the second drainage branch being used to discharge alkaline solution; the drainage assembly also includes: a second control valve, which is disposed on the first drainage branch to control the on / off state of the first drainage branch or to adjust the flow rate or velocity of the liquid medium in the first drainage branch; and / or a third control valve, which is disposed on the second drainage branch to control the on / off state of the second drainage branch or to adjust the flow rate or velocity of the liquid medium in the second drainage branch.
[0010] Furthermore, the multiple drainage branches also include a third drainage branch, which is connected to the middle of the first drainage branch and / or the middle of the second drainage branch.
[0011] Furthermore, the drainage assembly also includes a manual valve, which is installed on the third drainage branch pipe to control the on / off state of the third drainage branch pipe or to adjust the flow rate or velocity of the liquid medium in the third drainage branch pipe.
[0012] Furthermore, the second control valve and / or the third control valve are ball valves, and the drainage system also includes: a second detection device for detecting the working status of the ball valve, and opening the manual valve if the ball valve malfunctions.
[0013] Furthermore, the drainage system also includes: a timer; and a control module electrically connected to both the timer and the first detection device; wherein, when the count value of the timer reaches a preset value, the control module controls the first detection device to start and clear the count value.
[0014] According to another aspect of the present invention, a wire cutting device is provided, including the above-described drainage system.
[0015] The present invention provides a drainage system for discharging liquid from a liquid supply structure. The drainage system includes a first detection device and a drainage assembly. The first detection device detects the pH value of the liquid stored in the liquid supply structure. The drainage assembly includes a main drainage pipe and multiple branch drainage pipes. At least one branch drainage pipe is used to discharge slurry, and at least another branch drainage pipe is used to discharge alkaline solution. When the detection value of the first detection device is less than or equal to a preset value, it is determined that slurry is stored in the liquid supply structure. In this case, the slurry flows through the main drainage pipe into the branch drainage pipe used for discharging slurry and is discharged. When the detection value of the first detection device is greater than the preset value, it is determined that alkaline solution is stored in the liquid supply structure. In this case, the alkaline solution flows through the main drainage pipe into the branch drainage pipe used for discharging alkaline solution and is discharged. Thus, the first detection device replaces manual labor in accurately determining the type of liquid stored in the liquid supply structure, thereby solving the problem of increased labor intensity and waste liquid pollution caused by the existing drainage methods in photovoltaic silicon wafer slicing machines. This reduces the labor intensity of workers and avoids waste liquid pollution caused by misjudgment of liquid type. Attached Figure Description

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0025] To address the problems of increased labor intensity and waste liquid pollution caused by the existing liquid drainage methods in photovoltaic silicon slicing machines, this application provides a liquid drainage system and a wire cutting device incorporating the system.
[0026] like Figures 1 to 3 As shown, the drainage system is used to drain the liquid within the liquid supply structure 10. The drainage system includes a first detection device 20 and a drainage assembly 30. The first detection device 20 is used to detect the pH value of the liquid stored in the liquid supply structure 10. The drainage assembly 30 includes a main drainage pipe 31 and multiple branch drainage pipes 32. At least one branch drainage pipe 32 is used to drain slurry, and at least another branch drainage pipe 32 is used to drain alkaline solution. The first end of the main drainage pipe 31 is connected to the liquid supply structure 10. When the detection value of the first detection device 20 is less than or equal to a preset value, the second end of the main drainage pipe 31 is connected to the branch drainage pipe 32 used to drain slurry; when the detection value of the first detection device 20 is greater than the preset value, the other end of the main drainage pipe 31 is connected to the branch drainage pipe 32 used to drain alkaline solution.
[0027] Applying the technical solution of this embodiment, when the detection value of the first detection device 20 is less than or equal to a preset value, it is determined that slurry is stored in the liquid supply structure 10. At this time, the slurry enters the drain branch pipe 32 for discharging slurry through the drain main pipe 31 and is discharged. When the detection value of the first detection device 20 is greater than the preset value, it is determined that alkali is stored in the liquid supply structure 10. At this time, the alkali enters the drain branch pipe 32 for discharging alkali through the drain main pipe 31 and is discharged. Thus, the first detection device 20 replaces manual labor to accurately determine the type of liquid stored in the liquid supply structure 10, thereby solving the problem that the liquid discharge method of the photovoltaic silicon wafer slicing machine in the prior art increases the labor intensity of the workers and causes waste liquid pollution. This reduces the labor intensity of the workers and avoids waste liquid pollution caused by misjudgment of the liquid type.
[0028] In this embodiment, if the liquid supply structure 10 stores slurry, then the liquid stored in the liquid supply structure 10 is slurry; if the liquid supply structure 10 stores alkaline solution, then the liquid stored in the liquid supply structure 10 is alkaline solution.
[0029] In this embodiment, the preset value is 7. It should be noted that the preset value can be adjusted according to usage requirements and operating conditions.
[0030] In this embodiment, one drain branch pipe 32 is used to discharge slurry, and another drain branch pipe 32 is used to discharge alkaline solution, so as to achieve separate discharge of slurry and alkaline solution, thereby preventing waste liquid pollution and losses caused by misoperation.
[0031] like Figure 2 As shown, the first detection device 20 includes a pH meter and a housing 21. At least a portion of the pH meter extends into the liquid supply structure 10, and the housing 21 covers the pH meter. In this way, the pH meter can monitor the acidity or alkalinity of the liquid in real time to automatically identify the liquid type. The housing 21 protects the pH meter from external environmental influences, ensuring the accuracy of the detection and extending the service life of the pH meter.
[0032] like Figure 1 and Figure 2 As shown, the drainage assembly 30 also includes a first control valve 40. The first control valve 40 is installed on the drainage manifold 31 to control the on / off state of the drainage manifold 31 or to adjust the flow rate or velocity of the liquid medium within the drainage manifold 31. This arrangement of the first control valve 40 allows the drainage system to adjust the discharge rate and flow of the liquid medium as needed, and to control the operating status of the drainage system, reducing the operational difficulty for workers and improving the intelligence level of the drainage system.
[0033] In this embodiment, the precise adjustment function of the first control valve 40 enables the drainage system to flexibly adjust the drainage parameters, thereby realizing the automated drainage of the drainage system.
[0034] like Figure 3 As shown, the drainage assembly 30 also includes a pump body structure 33. The pump body structure 33 has an inlet and multiple outlets connected to the inlet. The inlet is connected to the second end of the main drainage pipe 31, and the multiple outlets are connected to multiple drainage branch pipes 32 in a corresponding manner. This arrangement of the pump body structure 33 ensures that the drainage system can extract slurry or alkali solution from the supply structure 10 and deliver it to the corresponding drainage branch pipes 32, thereby improving the drainage reliability and stability of the drainage system.
[0035] In this embodiment, the pump body structure 33 can transport slurry or alkali solution over long distances to different treatment units or discharge points, which not only simplifies the pipeline layout but also improves the continuity and efficiency of drainage.
[0036] Optionally, the pump body structure 33 is a pneumatic diaphragm pump. The pneumatic diaphragm pump uses compressed air as a power source, and a pneumatic mechanism drives the diaphragm inside the pump to move back and forth, thereby achieving the intake and discharge of slurry or alkali solution.
[0037] like Figure 3 As shown, the multiple drainage branches 32 include a first drainage branch 321 and a second drainage branch 322. The first drainage branch 321 is used to discharge slurry, and the second drainage branch 322 is used to discharge alkaline solution. The drainage assembly 30 also includes a second control valve 34, which is disposed on the first drainage branch 321 to control the on / off state of the first drainage branch 321 or to adjust the flow rate or velocity of the liquid medium within the first drainage branch 321; and / or, the drainage assembly 30 also includes a third control valve 35, which is disposed on the second drainage branch 322 to control the on / off state of the second drainage branch 322 or to adjust the flow rate or velocity of the liquid medium within the second drainage branch 322. Thus, the aforementioned arrangement of the second control valve 34 and / or the third control valve 35 enables the drainage system to adjust the discharge speed and flow rate of the liquid medium as needed and to control the operating status of the drainage system, reducing the operational difficulty for workers and improving the intelligence level of the drainage system.
[0038] In this embodiment, the drainage assembly 30 includes a second control valve 34 and a third control valve 35. The second control valve 34 is disposed on the first drainage branch pipe 321 and the third control valve 35 is disposed on the second drainage branch pipe 322, so as to intelligently control the first drainage branch pipe 321 and the second drainage branch pipe 322 respectively, thereby improving the intelligence level of the drainage system.
[0039] like Figure 3 As shown, the multiple drainage branch pipes 32 also include a third drainage branch pipe 323, which is connected to the middle of the first drainage branch pipe 321 and / or the middle of the second drainage branch pipe 322. Thus, the third drainage branch pipe 323 serves as a backup drainage branch pipe. In the event of a failure of the second control valve 34 or the third control valve 35, the slurry or alkali solution can be discharged through the third drainage branch pipe 323 to ensure the normal operation of the drainage system and improve its drainage reliability.
[0040] In this embodiment, the third drain branch pipe 323 is connected to the middle of the first drain branch pipe 321, and the second control valve 34 is located between the connection between the two and the pump body structure 33.
[0041] Specifically, the pneumatic diaphragm pump has three outlets. Two of the outlets are connected to the first drain branch pipe 321 and the second drain branch pipe 322, respectively, and are controlled to open and close by a pneumatic ball valve. The other outlet is connected to the third drain branch pipe 323 and is connected to the first drain branch pipe 321 by a manual ball valve.
[0042] In other embodiments not shown in the accompanying drawings, the third drainage branch pipe is independently provided as well as the first and second drainage branch pipes.
[0043] like Figure 3 As shown, the drainage assembly 30 also includes a manual valve 36. The manual valve 36 is installed on the third drainage branch pipe 323 to control the on / off state of the third drainage branch pipe 323 or to adjust the flow rate or velocity of the liquid medium within it. Thus, in the event of a malfunction of the second control valve 34 or the third control valve 35, the operator can manually open the manual valve 36 to discharge the slurry or alkali solution through the third drainage branch pipe 323, ensuring the normal operation of the drainage system and improving its reliability.
[0044] Specifically, the manual valve 36 provides an emergency control measure for the drainage system. It is applicable in situations where the second control valve 34 or the third control valve 35 fails or requires manual intervention. For example, in the event of a system malfunction or maintenance, operators can control the system via the manual valve 36, improving the safety and reliability of the drainage system. Thus, the aforementioned configuration of the manual valve 36 provides dual protection for the drainage system, ensuring normal system operation even in the event of automatic control failure through manual intervention.
[0045] Optionally, the second control valve 34 and / or the third control valve 35 are ball valves, and the drainage system also includes a second detection device. The second detection device is used to detect the operating status of the ball valve; if the ball valve malfunctions, the manual valve 36 is opened. Thus, the aforementioned configuration of the ball valve and the use of the second detection device enable the drainage system to monitor the operating status of the ball valve in real time. If the ball valve malfunctions, the manual valve 36 is manually opened to drain the fluid, thereby improving the drainage stability of the drainage system.
[0046] In this embodiment, both the second control valve 34 and the third control valve 35 are pneumatic ball valves.
[0047] Optionally, the drainage system also includes a timer and a control module. The control module is electrically connected to both the timer and the first detection device 20. When the timer's count reaches a preset value, the control module controls the first detection device 20 to start and clear the count. This configuration of the timer and control module enables the drainage system to periodically and automatically detect the pH of the liquid medium within the supply structure 10, improving the monitoring efficiency and production safety of the drainage system.
[0048] In this embodiment, the time interval for draining can be adjusted according to the alkaline washing frequency set or preset by the user, so as to intelligently adjust the alkaline washing frequency and further improve the intelligence of the draining system.
[0049] Optionally, the drainage system also includes a first support structure, a second support structure, a third support structure, and a fourth support structure. The first support structure is used to support and fix the pump body structure 33, the second support structure is used to support and fix the first control valve 40, the third support structure is used to support and fix the second control valve 34, and the fourth support structure is used to support and fix the third control valve 35, thereby improving the structural stability of the drainage system.
[0050] Optionally, the drain branch pipe 32 is made of a corrosion-resistant material. This allows the drain branch pipe 32 to resist corrosion from acidic and alkaline liquids, extending its service life and reducing maintenance costs.
[0051] Optionally, the first drain branch 321 and the second drain branch 322 are respectively provided with liquid type markings. In this way, the above-mentioned setting of liquid type markings enables operators to clearly identify different drain branches 32, which helps operators to quickly identify and operate the correct drain branch 32 in complex production environments, avoiding production accidents and environmental pollution caused by operational errors.
[0052] Optionally, the drainage assembly 30 also includes a filter disposed at the first end of the main drainage pipe 31. This filter configuration allows the drainage system to filter impurities in the slurry or alkali solution, preventing impurities from clogging the main drainage pipe 31 and / or the branch drainage pipe 32 and affecting the normal operation of the drainage system.
[0053] Optionally, the drainage system also includes an operation panel to start or stop drainage via the operation panel.
[0054] like Figure 1 As shown, this application also provides a wire cutting apparatus, including the above-described drainage system.
[0055] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0056] The drainage system is used to drain liquid from the liquid supply structure. The drainage system includes a first detection device and a drainage assembly. The first detection device detects the pH value of the liquid stored in the liquid supply structure. The drainage assembly includes a main drainage pipe and multiple branch drainage pipes. At least one branch drainage pipe is used to drain slurry, and at least another branch drainage pipe is used to drain alkaline solution. Thus, when the detection value of the first detection device is less than or equal to a preset value, it is determined that slurry is stored in the liquid supply structure. In this case, the slurry flows through the main drainage pipe into the branch drainage pipe used for slurry discharge and is discharged. When the detection value of the first detection device is greater than the preset value, it is determined that alkaline solution is stored in the liquid supply structure. In this case, the alkaline solution flows through the main drainage pipe into the branch drainage pipe used for alkaline discharge and is discharged. This system, by replacing manual labor, accurately determines the type of liquid stored in the liquid supply structure, thus solving the problems of increased labor intensity and waste liquid pollution associated with the existing drainage methods in photovoltaic silicon wafer slicing machines. It reduces the labor intensity of workers and avoids waste liquid pollution caused by misjudgment of liquid type.
