[0068] The working principle of the water treatment equipment is as follows: during water treatment, water containing impurities is conveyed from the water inlet pipe 3 to the middle layer filter screen 51.2, the water passes through the middle layer filter screen 51.2 and the lower layer filter screen 51.3 to flow to the bottom of the shell 1, and the impurities are intercepted on the middle layer filter screen 51.2 and the lower layer filter screen 51.3, during which, the motor 53.4 is started to drive the driving wheel 53.5 to rotate and drive the driven wheel 53.3 to rotate through the transmission belt 53.6, so that the driving shaft 53.1 drives the first filter screen 51 to rotate on the bearing 53.2, and drives the impurities on the middle layer filter screen 51.2 and the lower layer filter screen 51.3 to rotate, under the action of centrifugal force, the impurities on the middle layer filter screen 51.2 and the lower layer filter screen 51.3 move upwards on the inner side wall of the middle layer filter screen 51.2 to the top of the upper layer filter screen, in addition, the rotation of the first filter screen 51 enables the press wheel 55.2 to extrude the impurities on the upper layer to extrude the water in the impurities and pass through the upper layer filter screen 51.1 to flow to the bottom of the shell 1, and the impurities after extrusion move away from the axis of the middle layer filter screen 51.2 again under the action of centrifugal force, and finally fall from the edge of the upper layer filter screen 51.1 into the slot 54 of the collecting groove 52, in addition, the water in the middle layer filter screen 51.2 can also increase the speed of passing through the middle layer filter screen 51.2 under the action of centrifugal force, that is, the water filtration efficiency is improved;

[0069] During the extrusion of the impurities by the press wheel 55.2, the press wheel 55.2 moves upwards, drives the bracket 55.1 to move upwards on the guide rod 55.3, and makes the reset spring 55.5 deform, the press wheel 55.2 is subjected to the downward force by the elastic force of the reset spring 55.5, which not only ensures the reliability of the extrusion of the impurities by the roller, but also avoids being stuck;

[0070] The water in the impurities dropped into the notch 54 still remains, when the water in the impurities flows out, the water flows from the filter hole 61 to the bottom of the shell 1 through the second filter screen 62, the impurities in the notch 54 are intercepted by the second filter screen 62, at the same time, the rotation of the first filter screen 51 drives the knocking block 63.6 to rotate synchronously, so that the knocking block 63.6 intermittently pushes the transmission plate 63.5, when the knocking block 63.6 pushes the transmission plate 63.5, the transmission plate drives the rotating shaft 63.2 to rotate, the rotation of the rotating shaft 63.2 drives the scraper 63.1 to rotate synchronously, and the torsional spring 63.4 is deformed, when the knocking block 63.6 is separated from the transmission plate 63.5, the scraper 63.1 is reversely rotated by the elastic action of the torsional spring 63.4, the reverse rotation of the scraper 63.1 drives the transmission plate 63.5 to reversely rotate through the rotating shaft 63.2, so as to realize the reciprocating swing of the scraper 63.1, and further make the scraper 63.1 scrape the impurities on the second filter screen 62, so as to avoid the blockage of the second filter screen 62 caused by the impurities;

[0071] Finally, the filtered water at the bottom of the shell 1 is discharged from the water outlet pipe 4;

[0072] In addition, during the water filtration, the rotation of the driving shaft 53.1 drives the fan blade 75 to rotate, so that the air in the air collecting box 71 is discharged from the air pipe 72 and transported to the upper side of the first filter screen 51, then the air enters the air collecting box 71 from the air hole 74 after passing through the first filter screen 51 and the second filter screen 62, under the action of the wind force, not only the speed of the water passing through the first filter screen 51 and the second filter screen 62 is increased, that is, the filtration efficiency is improved, but also the evaporation of the water in the impurities in the collecting groove 52 is accelerated, so as to reduce the volume of the impurities in the collecting groove 52 and improve the impurity collecting capacity of the collecting groove 52;

[0076] S3, during the action of step S2, the impurities on the upper filter screen 51.1 are extruded by the extrusion assembly 55 to extrude the water in the impurities and flow to the bottom of the shell 1 through the upper filter screen 51.1, and the impurities after extrusion are transported to the notch 54 of the collecting groove 52 again by the centrifugal force;

[0077] S4, the water remaining in the impurities in the notch 54 flows from the filter hole 61 to the bottom of the shell 1 through the second filter screen 62, and the impurities are intercepted by the second filter screen 62;

[0078] S5, during the operation of step S4, the scraper 63.1 reciprocating swing, the scraper 63.1 scrape the impurities on the second filter screen 62, to avoid the impurities cause the second filter screen 62 blockage;

[0079] During the operation of steps S2 to S5, the air below the first filter screen 51 and the second filter screen 62 flows from the air pipe 72 to the above of the first filter screen 51 and the second filter screen 62 through the wind power mechanism 7, and the air above the first filter screen 51 and the second filter screen 62 flows to the below of the first filter screen 51 and the second filter screen 62 through the first filter screen 51 and the second filter screen 62, and the cycle is repeated; S6, the filtered water at the bottom of the shell 1 is discharged from the water outlet pipe 4.

[0080] As described above, the impurities intercepted on the first filter screen 51 are transported to the notch 54 by centrifugal force, realizing the automatic cleaning of the first filter screen 51, at the same time, the impurities on the second filter screen 62 are scraped by the scraper 63.1, realizing the automatic cleaning of the second filter screen 62, so that the frequency of cleaning the filter screen can be reduced, the working efficiency is improved, in addition, the rotation of the middle layer filter screen 51.2 is driven by the centrifugal force, the effect of passing through the middle layer filter screen 51.2 is improved, so as to improve the filtering efficiency, secondly, the water in the impurities is squeezed out by the squeezing of the pressure roller 55.2, and the water remaining in the impurities after squeezing is filtered by the second filter screen 62, not only saving water resources, but also facilitating the drying of the impurities in the later stage, and during the filtering process, the air passes through the first filter screen 51 and the second filter screen 62, driving the water to pass through the first filter screen 51 and the second filter screen 62, that is, improving the filtering efficiency, speeding up the evaporation of the water in the impurities in the collection tank 52, so as to reduce the volume of the impurities in the collection tank 52, and improve the collection capacity of the collection tank 52.
