[0042] According to an optional embodiment of the present invention, the pump device 11 is internally connected to a motor 12, a gearbox 13 and a pump body 15.

[0043] According to an optional embodiment of the present invention, the pump inlet pipe 16 is made of a heat-conducting material, a turntable 34 is slidably connected to the axle 14, a rotating cylinder 43 is fixedly connected to the axle 14, an annular groove 35 is provided on the turntable 34, and two centrifugal swing mechanisms are connected to the rotating cylinder 43.

The counterweight 41 is fixedly connected to the other end of the bending rod 40, and the bending rod 40 is rotatably connected to the rotating cylinder 43. The bending rod 40 is connected to the rotating cylinder 43 through the second spring 42.

[0044] The pump device 11 has a swing arm 36 rotatably connected to its inner wall via a rotating shaft 38. An extension wheel 37 and a push wheel 361 are rotatably connected to the swing arm 36. The extension wheel 37 is slidably connected to the inner wall of the annular groove 35. A transmission seat 18 is fixedly connected to the inner wall of the pump device 11. A lifting plate 26 is slidably connected to the inner wall of the transmission seat 18. The lifting plate 26 is connected to the inner wall of the transmission seat 18 via a spring 27. The right end of the lifting plate 26 extends to the outside of the transmission seat 18. The push wheel 361 abuts against the bottom wall of the lifting plate 26. Two electrical sockets 23 are fixedly connected to the 26. Two electrical slots 24 are opened on the electrical sockets 23. Conductive plates 25 are fixedly connected to the inner wall of the electrical slots 24. The conductive plates 25 are electrically connected to the power supply. Two heat-conducting seats 20 are fixedly connected to the outer wall of the pump inlet pipe 16. Cooling plates 19 are fixedly connected to the bottom wall of the heat-conducting seats 20. The cooling plates 19 are connected to an electrical connection plate 21 through wires. The electrical connection plate 21 is fixedly connected to the inner wall of the transmission seat 18. Two electrical plugs 22 are fixedly connected to the bottom wall of the electrical connection plate 21. There is a height difference between the two electrical connection plates 21.

[0045] According to an optional embodiment of the present invention, a fixing plate 29 is fixedly connected to the inner wall of the transmission seat 18, and an airbag 28 is fixedly connected to the bottom wall of the fixing plate 29. The airbag 28 abuts against the top wall of the lifting plate 26. A fixing rod 31 is fixedly connected to the inner wall of the pump body 15. Two steering plates 32 are rotatably connected to the fixing rod 31. An airbag 33 is fixedly connected between the two steering plates 32. The airbag 33 is connected to the airbag 28 through an air pipe 30.

[0046] According to an optional embodiment of the present invention, a frequency modulation circuit 44 is connected inside the pump device 11, and the frequency modulation circuit 44 is electrically connected to the motor 12. The frequency modulation circuit 44 is used to adjust the operating frequency of the motor 12, thereby indirectly controlling the rotational speed of the wheel shaft 14 and the impeller in the pump device 11.

[0047] Example 2:

[0048] When motor 12 is running, the output shaft of motor 12 is reduced by gearbox 13 and drives wheel shaft 14 and impeller to rotate. The impeller centrifugally drives the water entering the pump body 15 in the pump inlet pipe 16, so that the water enters the pump outlet pipe 17 and enters the heating device 56 for heating. High-temperature steam is generated and sprayed out through high-temperature pipe, quick connector and high-temperature steam gun to clean the crystalline silicon.

[0049] The rotation of the impeller creates a low-pressure zone near the pump inlet pipe 16 inside the pump body 15. Under low pressure, the boiling point of water drops significantly and it boils to produce bubbles. Multiple bubbles impact the impeller, causing cavitation.

[0050] The water flow directly impacts the impeller and shaft 14, causing turbulence. Both cavitation and turbulence can easily damage the internal components of the pump body 15.

[0051] When the wheel axle 14 rotates, the centrifugal force causes the two counterweights 41 to move away from each other against the elastic force of the second spring 42, thereby causing the bent rod 40 to rotate. The bent rod 40 drives the turntable 34 to move to the right through the connecting rod 39. The annular groove 35 on the turntable 34 drives the extension wheel 37 to move to the right. The swing rod 36 rotates clockwise around the rotating shaft 38, thereby causing the push wheel 361 to drive the lifting plate 26 to move upward against the elastic force of the first spring 27.

[0052] When the rotating drum 43 rotates at a low speed, cavitation and turbulence are less pronounced, the two counterweights 41 are closer together, the turntable 34 moves to the right a smaller distance, the swing arm 36 and the lifting plate 26 rotate a smaller amplitude, the lifting plate 26 moves up a smaller distance, the right electrical plug 22 does not contact the conductive plate 25, and the cooling plate 19 does not cool, thus saving energy.

[0053] When the rotating drum 43 rotates at a moderate speed, the cavitation and turbulence phenomena are moderate, the two counterweights 41 are moderately spaced, the turntable 34 moves moderately to the right, the swing arm 36 and the lifting plate 26 rotate moderately, the lifting plate 26 moves moderately upward, the two electrical plugs 22 on the right are respectively against the two conductive plates 25, the power supply is supplied to the right cooling plate 19, the cooling capacity of the right cooling plate 19 is transferred to the right heat conduction seat 20, and the right heat conduction seat 20 transfers the cooling capacity to the pump inlet pipe 16, thereby cooling the water, reducing the degree of boiling, reducing the generation of bubbles, and reducing cavitation.

[0054] When the rotating drum 43 rotates at a relatively high speed, cavitation and turbulence phenomena are greater, the two counterweights 41 are far apart, the turntable 34 moves a long distance to the right, the swing arm 36 and the lifting plate 26 rotate a large amplitude, the lifting plate 26 moves a large distance upward, the two electrical plugs 22 on the left side abut against the two conductive plates 25 respectively, the power supply is supplied to the cooling plate 19 on the left side, the cooling capacity of the two cooling plates 19 is transferred to the two heat conduction seats 20 respectively, and the two heat conduction seats 20 transfer the cooling capacity to the pump inlet pipe 16, thereby greatly cooling the water, reducing the boiling degree, reducing the generation of bubbles, and reducing cavitation phenomena.

[0055] The upward movement of the lifting plate 26 presses down on the first airbag 28, causing the gas inside the first airbag 28 to enter the second airbag 33 through the air pipe 30, causing the second airbag 33 to expand. This causes the two steering vanes 32 to open and tilt at a larger angle. The faster the wheel axle 14 rotates, the greater the turbulence. The greater the tilt of the steering vanes 32, the greater the water resistance, thereby reducing the direct impact of water on the impeller and wheel axle 14 and reducing the damage to components caused by turbulence.

[0056] After the rotational speed of the axle 14 decreases, the bending rod 40 moves backward under the elastic force of the second spring 42, causing the two cooling plates 19 to lose power and the two steering plates 32 to move closer to each other, reducing the impact on the water flow.

[0057] Beneficial effects of this embodiment:

[0058] The centrifugal swing mechanism on the rotating drum 43 is driven by the rotation of the wheel axle 14. Combined with the interaction between the counterweight 41 and the second spring 42, the position of the turntable 34 can be automatically adjusted according to the actual rotation speed, thereby adjusting the swing angle of the swing arm 36 and the displacement of the lifting plate 26. This enables intelligent hierarchical control of the working status of the pump inlet pipe 16 and the cooling element 19, achieving automatic detection of the wheel axle 14 speed without power and improving energy efficiency.

[0059] The displacement of the lifting plate 26 causes the electrical plug 22 to make on / off contact with the conductive plate 25, precisely controlling the start and stop of the cooling plate 19. When the speed is low, the cooling plate 19 does not work to avoid resource waste; at medium and high speeds, the right or both cooling plates 19 are activated respectively to adjust the cooling capacity to match different water temperature changes, resulting in a high degree of automation and stable temperature control.

[0060] The cooling energy released by the cooling plate 19 is conducted to the pump inlet pipe 16 through the heat conduction seat 20, which effectively suppresses the early boiling of water caused by low pressure, reduces the generation of bubbles, and thus reduces the frequency of cavitation, significantly improving the service life of the internal components of the pump body 15 and the stability of the device operation.

[0061] The lifting plate 26 simultaneously compresses the first airbag 28, and transmits the gas to the second airbag 33 through the air pipe 30, causing it to expand and drive the steering plate 32 to change its angle, thereby dynamically adjusting the water flow direction and resistance. This achieves the effect of automatically suppressing turbulence and splitting water pressure at high speeds, effectively reducing the direct impact of water flow on the wheel shaft 14 and impeller, and improving the overall durability of the device.

[0062] When the speed of wheel axle 14 decreases, spring 2 42 rebounds and drives the bending rod 40 to reset, causing the cooling chip 19 to be de-energized and stop working. The angle of steering plate 32 decreases to restore the original flow channel state, so that the entire dynamic control mechanism forms a closed loop, with good self-adaptation and automatic reset capabilities, without the need for external intervention.

[0063] The overall structure adopts a multi-level mechanical linkage and electronic control coordination method to realize multiple functions such as cavitation suppression, turbulence reduction, and dynamic cooling adjustment within the pump body 15. It is suitable for the fine control requirements of thermal sensitivity and impact intensity in the process of crystalline silicon cleaning, and significantly improves the reliability, safety and industrial applicability of the cleaning equipment.

[0067] The sealing ring 46 is located in the groove on the inner wall of the fixed joint 45. It is made of high-temperature resistant elastic material and is used to provide a reliable seal when high-temperature steam passes through, prevent steam leakage, and improve the safety of equipment operation.

[0068] Nut 47 is tightened onto the threaded outer wall of fixed connector 45 to securely lock pipe connector 50 and fixed connector 45, ensuring connection strength and sealing stability.

[0069] The protective cap 48 is fastened to the outside of the nut 47 to shield the surface of the high-temperature component, preventing operators from accidentally touching it and causing burns, and also has a certain dustproof function.

[0070] Nut clip 49 is installed on the outside of pipe fitting 50 to enhance its positioning and anti-loosening performance with nut 47, and to maintain reliable connection during repeated disassembly and assembly.
