[0044] Example 4

[0045] Based on the above embodiment 3, Figure 1-Figure 4 As shown, connecting rods 21 are symmetrically arranged on the inner wall of the tank body 1, and a second scraper 23 is fixedly arranged on one side of the connecting rods 21 that are close to each other, and the second scraper 23 is in contact with the filter cartridge 13; a knocking assembly is also arranged on the connecting rod 21, and the knocking assembly includes a fixed rod 25, and the fixed rod 25 is fixedly arranged on one side of the connecting rod 21, and a knocking rod 27 is hingedly arranged on the fixed rod 25, and a torsion spring 26 is arranged at the hinge position of the fixed rod 25 and the knocking rod 27, and a knocking head 28 is fixedly connected to the other end of the knocking rod 27, and a plurality of protrusions are arranged in a ring shape on the outer wall of the filter cartridge 13, and the knocking head 28 cooperates with the protrusions.

[0046] The working principle and beneficial effects of the above technical solution are as follows: when the filter cartridge 13 rotates, the fixed second scraper 23 will scrape the outer surface of the filter cartridge 13, and through the cooperation between the second scraper 23 and the first scraper 20, the filter cartridge 13 can always be in a relatively clean state, and the solid-liquid separation effect is more stable; while the filter cartridge 13 rotates, several protrusions of the filter cartridge 13 and the outer wall of the filter cartridge 13 will contact the knocking head 28. When the protrusions and the knocking head 28 contact, an extrusion force is formed on the knocking head 28. When the protrusions leave the contact position with the knocking head 28, the knocking head 28 is reset under the action of the torsion spring 26, thereby knocking on the outer wall of the filter cartridge 13, causing the filter cartridge 13 to vibrate, thereby accelerating the falling speed of impurities in the filter cartridge 13; reducing the adhesion of impurities to the filter cartridge 13, and improving its cleanliness and practicality.

The arc tube 14 will heat the wastewater and also simply dry the dried impurities, which can effectively reduce the moisture in the impurities and make the centrifugal drying effect of the entire device better; at the same time, when the hot air enters the arc tube 14, it will also enter the injection plate 22 from the connecting pipe 18, and then be ejected from a number of injection ports, thereby achieving a better mixing effect on the wastewater in the filter cartridge 13, and also achieving a drying effect, and its practicality and functionality are stronger.

[0056] The working principle and beneficial effects of the above technical solution are as follows: when the filter cartridge 13 rotates, the filter cartridge 13 drives the push rod 15 to rotate together; when the trapezoidal head 1 35 on the push rod 15 contacts the trapezoidal head 2 36, the trapezoidal head 1 35 drives the trapezoidal head 2 36 to move; the trapezoidal head 2 36 drives the sleeve 37 to move; the sleeve 37 drives the stabilizing plate 39 and the moving rod 42 to move together; the moving rod 42 drives the baffle plate 43 to move, thereby no longer blocking the drainage hole 44; when the moving rod 42 moves to the limit position and the push rod 15 continues to move, the trapezoidal head 1 35 causes the trapezoidal head 2 36 to drop, and the reset elastic member 38 presses The stabilizing plate 39 slides in the sleeve 37 (the stiffness coefficient of the resetting elastic member 38 is greater than the stiffness coefficient of the spring 41, which will cause the spring 41 to be compressed first); and when the trapezoidal head 1 35 is not in contact with the trapezoidal head 2 36, the baffle 43 blocks the drainage hole 44, so as to ensure that the water flow will remain in the tank body 1 for a period of time, so that the cleaning effect of the filter cartridge 13 will be better; and in order to speed up the centrifugal drying speed, those skilled in the art can set the drainage hole 44 to a normally open state or an intermittently open and closed state according to actual needs; its flexibility and the coordination of various parts are stronger, it has more functionality and higher practicality.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
