[0045] According to an optional embodiment of the present application, the inner wall of the transmission seat 18 is fixedly connected with a fixed plate 29, the bottom wall of the fixed plate 29 is fixedly connected with an air bag 28, the air bag 28 abuts against the top wall of the lifting plate 26, the inner wall of the pump body 15 is fixedly connected with a fixed rod 31, the fixed rod 31 is rotatably connected with two deflection sheets 32, the two deflection sheets 32 are fixedly connected with an air bag 33, and the air bag 33 is connected with the air bag 28 through an air pipe 30.

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

[0047] Embodiment two:

[0048] The motor 12 is running, and the output shaft of the motor 12 drives the wheel shaft 14 and the impeller to rotate after being decelerated by the gearbox 13. The impeller centrifugally drives the water in the pump inlet pipe 16 into the pump body 15, and the water is heated in the pump outlet pipe 17 and the heating device 56 to form high-temperature steam, which is sprayed out through the high-temperature pipe, the quick adapter, and the high-temperature steam spray gun to clean the crystalline silicon.

[0049] Due to the rotation of the impeller, a low-pressure area is formed near the pump inlet pipe 16 in the pump body 15, and the water boils to generate steam bubbles under the low-pressure state, which impact the impeller to cause cavitation.

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

[0051] When the wheel shaft 14 rotates, the two counterweights 41 overcome the spring force of the spring 42 and move away from each other under the action of centrifugal force, thereby rotating the bent rod 40. The bent rod 40 drives the rotating disc 34 to move to the right through the connecting rod 39, the annular groove 35 on the rotating disc 34 drives the extension wheel 37 to move to the right, and the swing rod 36 rotates clockwise around the rotating shaft 38, thereby driving the push wheel 361 to move upward against the spring force of the spring 27.

[0052] When the rotating drum 43 rotates at a low speed, the cavitation and turbulent flow are low, the two counterweights 41 are close to each other, the rotating disc 34 moves to the right by a small distance, the swing rod 36 and the lifting plate 26 rotate by a small amplitude, the lifting plate 26 moves upward by a small distance, and the right electric plug 22 does not abut against the conductive piece 25, so the refrigeration piece 19 does not refrigerate, thereby saving electric energy.

[0053] When the rotating drum 43 rotates at a medium speed, the cavitation and turbulent flow are medium, the two counterweights 41 are medium apart, the rotating disc 34 moves to the right by a medium distance, the swing rod 36 and the lifting plate 26 rotate by a medium amplitude, the lifting plate 26 moves upward by a medium distance, and the two electric plugs 22 on the right abut against the two conductive pieces 25, respectively. The power supply supplies power to the right refrigeration piece 19, the cold energy of the right refrigeration piece 19 is transmitted to the right heat-conducting seat 20, and the right heat-conducting seat 20 transmits the cold energy to the pump inlet pipe 16, thereby cooling the water, reducing the boiling degree, reducing the generation of steam bubbles, and reducing the cavitation.

[0054] When the rotating drum 43 rotates at a high speed, the cavitation and turbulence phenomena are large, the two counterweights 41 are far apart, the rotating disc 34 moves to the right for a long distance, the swing lever 36 and the lifting plate 26 rotate for a large amplitude, the lifting plate 26 moves upward for a large distance, the left two electric plugs 22 respectively abut against the two conductive sheets 25, the power supply supplies power to the left refrigeration sheet 19, and the cold energy of the two refrigeration sheets 19 is respectively transmitted to the two heat-conducting seats 20, and the two heat-conducting seats 20 transmit the cold energy to the pump water inlet pipe 16, so that the water is greatly cooled, the boiling degree is reduced, the generation of steam bubbles is reduced, and the cavitation phenomenon is reduced.

[0055] The upward movement of the lifting plate 26 presses the air bag 28, so that the gas in the air bag 28 enters the air bag 33 through the air pipe 30 to make the air bag 33 expand, so that the two deflection sheets 32 are opened and the inclination angle is increased, the rotating speed of the axle 14 is faster, the turbulence phenomenon is larger, and the inclination of the deflection sheet 32 is larger, and the water blocking performance is larger, so that the impact force of the water directly on the impeller and the axle 14 is reduced, and the damage degree of the turbulence phenomenon on the components is reduced.

[0056] After the rotating speed of the axle 14 is reduced, the reverse movement of the bent rod 40 under the elastic force of the spring 42 makes the two refrigeration sheets 19 lose power, and the two deflection sheets 32 are close to each other, and the influence on the water flow is reduced.

[0057] The embodiment has the following beneficial effects:

[0058] Through the rotation of the axle 14 to drive the centrifugal swing mechanism on the rotating drum 43, combined with the interaction of the counterweight 41 and the spring 42, the position of the rotating disc 34 can be automatically adjusted according to the actual rotating speed, so as to adjust the swing angle of the swing lever 36 and the displacement of the lifting plate 26, realize the intelligent grading control of the working state of the refrigeration sheet 19 of the pump water inlet pipe 16, realize the automatic detection of the rotating speed of the axle 14 without power, and improve the energy saving performance;

[0059] The displacement of the lifting plate 26 drives the on-off contact of the electric plug 22 and the conductive sheet 25, and the refrigeration sheet 19 is accurately controlled to start and stop. When the rotating speed is low, the refrigeration sheet 19 does not work, so as to avoid resource waste; when the rotating speed is medium and high, the right or both sides of the refrigeration sheet 19 is started, respectively, to adjust the cold energy to match the different water temperature change requirements, so as to be high in automation degree and stable in temperature control;

[0060] The cold energy released by the refrigeration sheet 19 is conducted to the pump water inlet pipe 16 through the heat-conducting seat 20, so as to effectively inhibit the early boiling of the water flow caused by low pressure, reduce the generation of steam bubbles, and further reduce the generation frequency of the cavitation phenomenon, and significantly improve the service life of the internal components of the pump body 15 and the running stability of the device;

[0061] The lifting plate 26 drives the air bag 28 to be pressed at the same time, the gas is transmitted to the air bag 2 through the air pipe 30, the air bag 2 is inflated, and then the angle of the deflection piece 32 is changed, so that the water flow direction and resistance are dynamically adjusted, the effect of automatically inhibiting turbulent flow and shunting water pressure at high rotating speed is realized, the direct impact force of water flow on the axle 14 and the impeller is effectively reduced, and the durability of the whole device is improved.

[0062] When the rotating speed of the axle 14 is reduced, the spring 2 is rebounded to drive the bent rod 40 to reset, drive the refrigeration piece 19 to stop working, and the angle of the deflection piece 32 is reduced to restore the original flow channel state, so that the whole dynamic regulation mechanism forms a closed loop, has good self-adaptation and automatic reset capability, and does not need external intervention.

[0063] In the whole structure, a multi-stage mechanical linkage and electric control cooperative control mode is adopted, the functions of pump body 15 cavitation inhibition, turbulent flow reduction, cooling dynamic regulation and the like are realized, the fine control requirements of heat sensitivity and impact intensity in the crystalline silicon cleaning process are met, and the reliability, safety and industrial applicability of the cleaning equipment are significantly improved.
