Description

Technical Field

[0001] The present application relates to the technical field of solar cell panels, and in particular to an additive refilling system. Background Art

[0002] During the mass production of silicon wafers, they undergo acid etching and alkaline polishing. In tank-type cleaning equipment and tank-type wet processing equipment for solar silicon wafers, when the same tank is used in different processes (commonly known as switching between different acid or alkaline solutions), it is necessary to first achieve acid-base balance before rinsing the tank. The usual practice is to manually pour additives into an additive barrel, then add the appropriate proportion of acid or alkaline solution to the tank to achieve acid-base balance. Finally, hot pure water is manually poured into the barrel to clean the residual solution and crystals. However, this manual pouring of additives poses a risk of injury from splashing acid or alkaline solutions, posing a safety hazard. Furthermore, the process is cumbersome and inconvenient.

[0025] The following is a detailed description of an additive rehydration system provided by this embodiment in conjunction with the accompanying drawings. Figure 1-Figure 3 As shown, it includes: a liquid supply device 1, a liquid storage device 2 and a metering device 3; wherein the liquid supply device 1 is used to deliver additives to multiple liquid storage devices 2; the liquid storage devices 2 are provided in plurality, and each liquid storage device 2 is independently connected to the liquid supply device 1, and the liquid storage device 2 is used to temporarily store additives; the metering device 3 is provided in multiple groups, each group of metering devices 3 corresponds to each liquid storage device 2, and the number of metering devices 3 in each group is multiple, and the multiple metering devices 3 in each group are independently connected to the corresponding liquid storage device 2, and the metering device 3 is used to meter the additives to be added and add them to the liquid tank 4.

[0026] In this embodiment, a liquid supply device 1 is used to transport additives to multiple liquid storage devices 2. The additives are temporarily stored in each liquid storage device 2. Then, the liquid storage device 2 transports the additives to the metering device 3. The additives to be added are metered in the metering device 3. After metering, the additives are automatically added to the liquid tank 4 through the metering device 3. Therefore, by adopting the automatic addition method of additives, the risk of splashing acid and alkali liquids that hurt the human body when manually pouring additives is effectively eliminated. In addition, this method has a simple process and is easy to operate.

[0027] Please continue to refer to Figure 1-Figure 3As shown, in this embodiment, it should be noted that the liquid supply device 1 includes a centralized liquid supply station 11 and a centralized liquid supply pipeline 12. The centralized liquid supply pipeline 12 includes multiple independently set liquid addition pipes 121. The multiple liquid addition pipes 121 are connected in parallel to the centralized liquid supply station 11. The multiple liquid addition pipes 121 are arranged in a one-to-one correspondence with the multiple liquid storage devices 2 set up subsequently, that is, one liquid addition pipe 121 supplies additives to one liquid storage device 2 without interfering with each other. The liquid inlet of the liquid addition pipe 121 is connected to the centralized liquid supply station 11, and the liquid outlet of the liquid addition pipe 121 is connected to the liquid storage device 2. The centralized liquid supply station 11 distributes the additives to the multiple liquid addition pipes 121, and then the multiple liquid addition pipes 121 independently transport the additives to each liquid storage device 2. Each liquid addition pipe 121 does not interfere with each other. The multiple independent drug liquid addition pipes 121 provided in this embodiment may be two, three, four or more. In this embodiment, only four drug liquid addition pipes 121 are taken as an example for description.

[0028] In some embodiments, each liquid medicine addition pipe 121 is provided with a first manual valve 122 and a first automatic valve 123, and all the first manual valves 122 are installed in a fixed valve box that is easy to operate manually, and all the first automatic valves 123 are collected on a fixed valve seat. Preferably, the first manual valve 122 is provided at the front end of the first automatic valve 123, and the first manual valve 122 is preferably a manual diaphragm valve, and the first automatic valve 123 is preferably a pneumatic diaphragm valve. A first manual valve 122 and a first automatic valve 123 are separately provided on each liquid medicine addition pipe 121 for independent control, and the corresponding liquid medicine addition pipe 121 can be selected and controlled to deliver additives according to actual needs, which is more flexible to use. Different additives can also be delivered separately in each liquid medicine addition pipe 121 without interfering with each other.

[0029] In some embodiments, a main flushing pipe 13 is also separated from the centralized liquid supply station 11, and a main flushing valve 15 is provided on the main flushing pipe 13. The main flushing valve 15 is used to control the on and off of hot pure water. Multiple bypass flushing pipes 14 are connected in parallel on the pipeline after the main flushing valve 15. The multiple bypass flushing pipes 14 are arranged in a one-to-one correspondence with the multiple liquid addition pipes 121, that is, one bypass flushing pipe 14 corresponds to one liquid addition pipe 121, that is, each liquid addition pipe 121 is separately configured with a bypass flushing pipe 14 for flushing. The bypass flushing pipe 14 is connected to the liquid addition pipe 121 after the first manual valve 122 and / or the first automatic valve 123. Preferably, the bypass flushing pipe 14 is connected to the liquid addition pipe 121 between the first manual valve 122 and the first automatic valve 123. It should be noted that the front and rear pipeline positions of the first manual valve 122 or the first automatic valve 123 are distinguished by the direction of liquid flow, such as the direction before the first manual valve 122 is the direction of liquid inflow, and the direction after the first manual valve 122 is the direction of liquid outflow. Each bypass flushing pipe 14 is also provided with a second automatic valve 16. The provision of the second automatic valve 16 can prevent additives from flowing into the bypass flushing pipe 14. Similarly, the main flushing valve 15 is installed in a fixed valve box that is easy to operate manually, and all the second automatic valves 16 are gathered on the fixed valve seat. Preferably, the main flushing valve 15 adopts a manual ball valve, and the second automatic valve 16 adopts a pneumatic diaphragm valve. Each liquid medicine adding pipe 121 is correspondingly provided with a bypass flushing pipe 14 . After the liquid medicine adding pipe 121 delivers the additive, hot pure water can be delivered through the bypass flushing pipe 14 to flush the liquid medicine adding pipe 121 .

[0030] In this embodiment, it should also be noted that the liquid storage device 2 includes a liquid storage sub-tank 21. The top of the liquid storage sub-tank 21 is provided with an inlet, which is connected to the liquid outlet of the liquid addition tube 121. The bottom of the liquid storage sub-tank 21 is provided with a first outlet, which is connected to a main liquid infusion tube 22. The main liquid infusion tube 22 is provided with a main liquid infusion valve 24 and a pneumatic pump 25 in sequence. The main liquid infusion valve 24 is used to control the on-off flow of additives in the main liquid infusion tube 22, and the pneumatic pump 25 is used to pump the additives out of the liquid storage sub-tank 21. Multiple bypass liquid infusion tubes 23 are connected in parallel on the pipeline after the pneumatic pump 25. The multiple bypass liquid infusion tubes 23 correspond to and are connected to the multiple metering addition devices 3 in each group. Each bypass liquid infusion tube 23 is provided with a one-way valve 26 and a third automatic valve 27 in sequence. Preferably, the main liquid infusion valve 24 is a manual ball valve, and the third automatic valve 27 is a pneumatic diaphragm valve. A plurality of bypass infusion pipes 23 are branched out in parallel from the main infusion pipe 22, and each bypass infusion pipe 23 independently delivers additives to each metering addition device 3. Thus, the corresponding bypass infusion pipe 23 can be selected and controlled to deliver additives to the metering addition device 3 according to actual needs, which is more flexible to use.

[0031] In addition, the liquid storage sub-tank 21 is also equipped with low, medium and high liquid level sensing systems. The low liquid level alarm protects the pneumatic pump 25, the medium liquid level prompts liquid replenishment, and the high liquid level stops liquid replenishment, and it has a leakage detection alarm.

[0032] In some embodiments, a second outlet is further provided at the bottom of the liquid storage sub-tank 21, which is connected to a waste pipe 28. A waste valve 29 is provided on the waste pipe 28. Preferably, the waste valve 29 can be a manual valve, such as a manual ball valve, or an automatic valve. Flushing liquid flowing through the flushing liquid addition pipe 121 and the liquid storage sub-tank 21 can be directly discharged into the waste pipe 28 and then discharged through the waste pipe 28.

[0033] Therefore, the centralized liquid supply pipeline 12 in this embodiment has a hot water flushing function, which can automatically and regularly flush the liquid addition pipe 121 and the liquid storage sub-tank 21 inner wall of the liquid residue and crystals. The flushing liquid can be directly discharged through the waste pipe 28. The above cleaning process can be completed without affecting the wool making rhythm, thereby improving production efficiency.

[0034] Please continue to refer to Figure 1-Figure 3 As shown, in this embodiment, it should be noted that the metering addition device 3 includes a liquid medicine buffer tank 31, which is equipped with a meter. The liquid inlet of the liquid medicine buffer tank 31 is connected to the bypass infusion tube 23, and the liquid outlet of the liquid medicine buffer tank 31 is connected to the liquid medicine tank 4 through a liquid outlet pipe 32. A fourth automatic valve 33 is provided on the liquid outlet pipe 32. The third automatic valve 27 is controlled to open, and the bypass infusion pipe 23 conveys the additive into the liquid medicine buffer tank 31. At the same time, it is measured by the meter. When the required amount of medicine is reached, the third automatic valve 27 is controlled to close, and the fourth automatic valve 33 on the liquid outlet pipe 32 is opened, so that the texturing additive can be added to the liquid medicine tank 4.

[0035] In some embodiments, a calibration bypass line 34 extends from the liquid outlet line 32 above the fourth automatic valve 33. This line is connected to a calibration bucket 35 and is provided with a fifth automatic valve 36. The meter in the liquid buffer tank 31 may experience inaccuracies over extended periods of measurement, which cannot be visually detected. Therefore, the calibration bypass line 34 is provided to discharge the additive measured in the liquid buffer tank 31 into the calibration bucket 35 for calibration and then to waste after calibration is complete.

[0036] In some embodiments, an overflow port is also provided on the medicine liquid buffer tank 31, and the overflow port is connected to an overflow pipe 37. The additives in the medicine liquid buffer tank 31 flow to the medicine liquid tank 4 through the liquid outlet pipe 32 at the bottom. If the liquid outlet pipe 32 is blocked by debris, the waste liquid in the medicine liquid buffer tank 31 is discharged through the overflow pipe 37, and the equipment performs an alarm prompt.

[0037] In this embodiment, it should also be noted that the liquid storage sub-tank 21 and the liquid buffer tank 31 are both made of plastic, and the volume of the liquid storage sub-tank 21 is not less than 50L. All automatic valves and metering devices of the liquid buffer tank 31 are interlocked and controlled by an automatic controller.

[0038] The implementation principle of this embodiment is: when the texturing additive needs to be used normally, manually open the first manual valve 122 on the liquid addition pipe 121, and close the main flushing valve 15 on the main flushing pipe 13. The automatic controller controls the opening of the first automatic valve 123, and the texturing additive flows to each liquid storage sub-tank 21 through each liquid addition pipe 121; manually open the main infusion valve 24, close the waste valve 29, and the automatic controller controls the opening of the third automatic valve 27. At this time, the texturing additive flows to the liquid buffer tank 31 through each bypass infusion pipe 23 and starts metering; when the required amount of medicine is reached, the automatic controller controls the closing of the third automatic valve 27 and opens the fourth automatic valve 33 on the liquid outlet pipe 32, and the texturing additive can be added to the liquid tank 4. Similarly, texturing additives can also be added to other liquid tanks 4. Similarly, different texturing additives can also be replaced.

[0039] When the acid-base balance is reached in the liquid tank 4, stop adding the medicine. When hot water cleaning is needed, first close the first manual valve 122 on the liquid adding pipe 121, then open the main flushing valve 15 on the main flushing pipe 13, and the automatic controller controls the opening of the second automatic valve 16 on the bypass flushing pipe 14. Hot pure water will flow through the bypass flushing pipe 14 and then through the liquid adding pipe 121 into the liquid storage sub-tank 21 to perform thermal cleaning on the inner wall of the centralized liquid supply pipeline 12 of the additive and the liquid storage sub-tank 21. Open the waste valve 29, and the flushing liquid for cleaning the centralized liquid supply pipeline 12 and the liquid storage sub-tank 21 can be directly discharged through the waste pipe 28. The above cleaning process can be completed without affecting the textile making rhythm, while also eliminating the risk of splashing acid and alkali liquids harming the human body and efficiently removing liquid residues.

[0040] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
