[0034] During the photovoltaic silicon wafer production process, when the silicon rods enter the cutting chamber of the slicer for cutting, the cutting chamber needs to be flushed to keep the cleaning chamber and the silicon rods clean.
[0035] In order to ensure that the cutting chamber and silicon rods are rinsed clean, the cutting chamber needs to be rinsed with pure water. During the flushing process, a water gun is usually used to pressurize the pure water to achieve better cleaning effect.
[0036] However, during the cleaning process, a large amount of pure water is required to directly use a water gun to pressurize and flush the cutting chamber and silicon rods.
[0037] In order to solve the above problems, the present application provides a cleaning device, which provides a suction mixing piece at the air outlet of the cleaning gun and connects a self-priming tube to the suction mixing piece. When the gas flows through the suction mixing piece, the cleaning liquid in the water tank is drawn into the suction mixing piece and mixed with the gas, and then sprayed out through the regulating component; the silicon rod and the cutting chamber are flushed by a gas-liquid mixture, and a high-speed jet is formed by the combination of high-pressure gas and cleaning liquid to increase the mechanical impact energy so as to effectively flush the dirt on the surface of the cutting chamber; at the same time, the high-speed impact of the gas and the dispersion effect of the liquid work together to improve the utilization rate of the cleaning liquid, while ensuring the cleaning effect, reducing the use of cleaning liquid.
[0038] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.
[0039] This application provides a cleaning device, referring to Figure 1 and Figure 2 The cleaning device includes a cleaning gun 100, a suction mixing element 200, a water tank 300, a self-suction pipe 400 and an adjustment component 500.
[0040] The cleaning gun 100 is used to connect with the gas source to eject gas. The suction mixing element 200 is arranged at the gas outlet of the cleaning gun 100. One end of the suction pipe 400 is connected to the suction mixing element 200, and the other end is connected to the water tank 300, so that when the gas flows through the suction mixing element 200, the liquid in the water tank 300 is sucked into the suction mixing element 200 to mix with the gas; the adjustment component 500 is arranged at the outlet end of the suction mixing element 200 to adjust the spray area of the outlet end of the suction mixing element 200.
[0041] In the embodiment of the present application, the suction mixing element 200 is a venturi tube, and the self-suction pipe 400 is connected to the throat of the venturi tube.
[0042] By adopting the above technical solution, a Venturi tube is provided at the air outlet of the cleaning gun 100, and a self-priming tube 400 is connected to the throat of the Venturi tube. When the gas flows through the throat of the Venturi tube, the flow rate is accelerated, so that a pressure drop is generated at the end of the self-priming tube 400, and the cleaning liquid in the water tank 300 is drawn into the Venturi tube and mixed with the gas, and then sprayed out through the regulating component 500; the silicon rod and the cutting chamber are cleaned by the gas-liquid mixing method, which reduces the use of cleaning liquid and the waste of water resources.
[0043] The cleaning gun 100 is connected to an external air source, which can be an air compressor or other suitable equipment. To ensure the cleanliness of the silicon rods, certain requirements may be set for the gas supplied, such as inert gas or cleaned air. In this embodiment of the present application, the cleaning liquid in the water tank 300 is pure water to ensure effective rinsing of the silicon rods.
[0044] Before the slicer in the cutting chamber officially cuts, the cleaning gun 100 is used to flush the edges and corners of the cutting chamber. When the cleaning water gun switch is manually turned on, compressed air enters the cleaning gun 100. When the compressed air passes through the roar of the suction mixing element 200, according to the principle of Bernoulli's equation, the pressure is low where the flow rate is high and the pressure is high where the flow rate is low. The pressure at this location becomes smaller. Under the action of negative pressure, the cleaning liquid in the water tank 300 enters the suction mixing element 200 through the self-priming hose and mixes with the compressed air, and is finally sprayed out from the adjustment component 500.
[0045] In some embodiments, reference Figure 2 and Figure 3 The adjustment component 500 includes a nozzle 510 and an adjustment member 520. The nozzle 510 is provided with a first outlet 511 and a second outlet 512. The first outlet 511 and the second outlet 512 are both connected to the suction mixing member 200. The adjustment member 520 is provided on the nozzle 510 and is configured to selectively open the first outlet 511 or the second outlet 512.
[0046] The nozzle 510 is threadedly connected to the outlet end of the suction mixing element 200, and the adjustment element 520 is installed on the nozzle 510 to select either the first outlet 511 or the second outlet 512 to open, thereby changing the spraying area of the gas-liquid mixture sprayed from the nozzle 510 to adapt to different flushing positions and improve the cleaning effect.
[0047] In some embodiments, the diameter of the first outlet 511 at an end close to the suction mixing element 200 is larger than the diameter of the first outlet 511 at an end away from the suction mixing element 200 .
[0048] The first outlet 511 is a gradually shrinking circular hole, so that the gas-liquid mixture sprayed from the nozzle 510 is sprayed in a columnar shape, increasing the spraying pressure to flush away impurities and reduce impurities adhering to the cutting chamber and silicon rods.
[0049] In some embodiments, reference Figure 3 and Figure 4 The second outlet 512 is an arc-shaped outlet. The diameter of the second outlet 512 is larger than that of the first outlet 511 . The diameter of the second outlet 512 at the end away from the suction mixing element 200 is larger than the diameter of the second outlet 512 at the end close to the suction mixing element 200 .
[0050] The second outlet 512 is an arc-shaped opening, and the end of the second outlet 512 away from the suction and mixing element 200 is tilted toward the center axis of the nozzle 510. That is, the diameter of the second outlet 512 away from the suction and mixing element 200 is larger than the diameter of the second outlet 512 near the suction and mixing element 200. This allows the gas-liquid mixture to spread outward after being ejected from the second outlet 512, forming a larger arc-shaped mist surface, increasing the flushing area and further reducing the amount of cleaning fluid used. The centers of the first outlet 511 and the second outlet 512 coincide.
[0051] In other embodiments, the end of the nozzle 510 can be set as a cover, and circular holes can be opened in a ring shape on the cover to radiate spraying.
[0052] In some embodiments, reference Figure 3 and Figure 4 The adjusting member 520 includes an adjusting plate, on which a first communicating groove 521 and a second communicating groove 522 are provided. The first communicating groove 521 is used to communicate with the first outlet 511, and the second communicating groove 522 is used to communicate with the second outlet 512. The adjusting plate is slidably inserted on the nozzle 510. When the first communicating groove 521 is connected with the first outlet 511, the second communicating groove 522 is misaligned with the second outlet 512. When the second communicating groove 522 is connected with the second outlet 512, the first communicating groove 521 is misaligned with the first outlet 511.
[0053] The nozzle 510 is provided with an adjustment slot, into which an adjustment plate is slidably inserted, sliding in a direction perpendicular to the axis of the nozzle 510. The first connecting slot 521 is a circular hole that mates with the first outlet 511, and the second connecting slot 522 is an arc-shaped hole that mates with the second outlet 512. The distance between the center of the first connecting slot 521 and the center of the second connecting slot 522 is greater than or equal to the diameter of the first connecting slot 521, ensuring that only a single channel is connected during use.
[0054] The adjustment plate is further provided with a slider 523, and a chute 524 is provided in the nozzle 510. The slider 523 is slidably connected to the chute 524. When the slider 523 moves to one end of the chute 524 and abuts against the side wall of the chute 524, the first connecting groove 521 is connected to the first outlet 511. When the slider 523 moves to the other end of the chute 524 and abuts against the side wall of the chute 524, the second connecting groove 522 is connected to the second outlet 512. This prevents the adjustment plate from falling and facilitates the operator to move the adjustment plate to the appropriate position, thus achieving a positioning effect.
[0055] Furthermore, a clamping block can be provided on the slider 523. When the slider 523 moves to both ends of the slide groove 524, the slider 523 can be clamped and fixed in the slide groove 524 to fix the adjustment plate and prevent the adjustment plate from slipping.
[0056] By adopting the above technical solution, at the start, the second connecting groove 522 on the adjustment plate is connected to the second outlet 512. The cleaning liquid and gas are mixed in the suction mixing element 200 and then enter the nozzle 510. They are then sprayed out from the second outlet 512 in an arc-shaped diffusion pattern through the second connecting groove 522 to increase the cleaning area. If the cleaning force is insufficient or some areas are difficult to clean, the adjustment plate is moved and pushed to the bottom, so that the first connecting groove 521 is connected to the first outlet 511 and the second connecting groove 522 is separated from the second outlet 512. The nozzle 510 is switched to water column mode, and the spray pressure is increased to increase the cleaning force.
[0057] In some embodiments, reference Figure 2 A flow regulating valve 410 is provided on the self-suction pipe 400 , and the flow regulating valve 410 is used to adjust the flow of the self-suction pipe 400 .
[0058] The provision of the flow control valve 410 is conducive to regulating the mixing ratio of the gas and the cleaning liquid, thereby further reducing the use of the cleaning liquid while ensuring the cleaning effect.
[0059] In some embodiments, reference Figure 2 The cleaning gun 100 is provided with a hanging ring 110 for hanging the cleaning gun 100 .
[0060] The provision of the hanging ring 110 is conducive to placing the cleaning gun 100 and keeping the site tidy.
[0061] In some embodiments, a pressure sensor is provided on the hanging ring 110 , and the pressure sensor is electrically connected to the flow regulating valve 410 . When the pressure sensor detects that the hanging ring 110 is under pressure, the pressure sensor controls the flow regulating valve 410 to close the self-suction pipe 400 .
[0062] A pressure sensor is mounted on the inner ring of the hanging ring 110. The pressure sensor is electrically connected to the flow control valve 410. Furthermore, the flow control valve 410 is equipped with a microcontroller to adjust the opening of the flow control valve 410 based on information from the pressure sensor. In the embodiment of the present application, after the cleaning gun 100 is hung, the pressure sensor detects the pressure and transmits a pressure signal to the controller on the flow control valve 410. The controller is set to a preset pressure. When the pressure detected by the pressure sensor is greater than or equal to the preset pressure, the controller controls the flow control valve 410 to close the self-priming pipe 400. This allows the self-priming pipe 400 to automatically close after the cleaning gun 100 is placed, further reducing waste of cleaning fluid.
[0063] In some embodiments, a cover plate 310 is provided on the water tank 300 , and a water inlet 311 and a water outlet 312 are provided on the cover plate 310 . The suction pipe 400 passes through the water outlet 312 and is plugged into the bottom of the water tank 300 .
[0064] The water inlet 311 is used to replenish cleaning liquid into the water tank 300. During use, it also plays a role in connecting the air pressure inside and outside the water tank 300 to ensure the normal occurrence of self-priming.
[0065] In some embodiments, a weighted collar is provided at one end of the self-priming pipe 400 located in the water tank 300 , so that the end of the self-priming pipe 400 is located at the bottom of the water tank 300 .
[0066] The weighted collar is fixed to one end of the self-priming pipe 400 located in the water tank 300 so that the self-priming pipe 400 can sink to the bottom of the water tank 300 to ensure the absorption of the cleaning liquid.
[0067] The present application provides a cleaning device, which provides a suction mixing piece 200 at the air outlet of a cleaning gun 100, and connects a self-suction pipe 400 to the throat of the suction mixing piece 200. When the gas flows through the throat of the suction mixing piece 200, the flow rate is accelerated, so that a pressure drop is generated at the end of the self-suction pipe 400, and the cleaning liquid in the water tank 300 is drawn into the suction mixing piece 200 to mix with the gas, and then sprayed out through the regulating component 500; the silicon rod and the cutting chamber are flushed by a gas-liquid mixture, and a high-speed jet is formed by combining high-pressure gas and cleaning liquid to increase the mechanical impact energy, so as to effectively flush the dirt on the surface of the cutting chamber; at the same time, the high-speed impact of the gas and the dispersion effect of the liquid work together to improve the utilization rate of the cleaning liquid, while ensuring the cleaning effect, reducing the use of cleaning liquid.
