[0035] Specifically, the first direction can be set to the clockwise direction, and the second direction can be set to the counterclockwise direction, that is, when the driving mechanism 4 is driven clockwise, the driving mechanism 4 drives the first purification layer 23 to rotate clockwise, so that the first filter element 232 corresponding to the filtering effect is rotated to correspond to the position of the liquid outlet 213; when the driving mechanism 4 drives the second purification layer 3 to rotate counterclockwise, the second filter element 32 corresponding to the filtering effect is rotated to correspond to the position of the liquid outlet 213, thereby achieving the corresponding filtering effect; in this way, by rotating the first purification layer 23 and the second purification layer 3 respectively, it is possible to conveniently select any two layers of the first filter element 232 and the second filter element 32 with different filtering effects to be superimposed and then filter the sewage, thereby achieving different purification effects, and the sewage purification treatment is more flexible, so as to flexibly respond to various complex water quality problems, improve sewage treatment efficiency and reduce structural costs.

[0045] like Figures 1 to 4 As shown, a purification device of this embodiment, in some embodiments, the purification component 2 also includes a second shell 21 and a base 22; the second shell 21 is provided with a liquid inlet 211 and a tube body 212 extending therefrom; the base 22 is rotatably arranged at the bottom of the tube body 212 and forms a buffer cavity with the second shell 21; the tube body 212 is provided with a liquid outlet 213 connected to the buffer cavity at a position corresponding to the liquid discharge port 11; the first purification layer 23 is arranged around the outer periphery of the tube body 212; the first purification layer 23 is movably engaged with the base 22.

[0046] Specifically, during installation, the second purification layer 3 is rotated and placed in the first shell 1, and then the base 22 is rotated and installed at the bottom of the tube body 212, and then the first purification layer 23 and the base 22 are clamped and installed from bottom to bottom. After the purification component 2 is installed, the entire purification component 2 is inserted into the first shell 1, thereby realizing modular installation of the purification device, facilitating replacement and maintenance, and reducing the use cost;

[0047] According to the actual water purification demand, the first purification layer 23 and the second purification layer 3 are driven to rotate respectively by the driving mechanism 4, so that the required first filter element 232 and the second filter element 32 are selected and rotated to the positions corresponding to the position of the discharge port 11, and then the sewage to be purified is pumped into the buffer cavity through the liquid inlet 211, and the sewage in the buffer cavity is discharged from the buffer cavity through the liquid outlet 213, and then filtered by the first filter element 232 and the second filter element 32, and then discharged from the discharge port 11, so as to obtain purified liquid.

[0048] like Figure 1 , Figure 4 and Figure 5 As shown, a purification device of this embodiment, in some embodiments, a first purification layer 23 has an inner wall provided with a snap-in groove, a first snap-in pin 221 and a second snap-in pin 222 elastically provided on the first snap-in pin 221 are elastically provided on the base 22, the first snap-in pin 221 and the second snap-in pin 222 are coaxially arranged, the first snap-in pin 221 and the second snap-in pin 222 are movably embedded in the snap-in groove, and the second housing 21 is provided with at least two first springs 214, and the first spring 214 is movably abutted against the top of the first purification layer 23. In this embodiment, a first sliding hole is provided on the base 22, a first return spring is provided in the first sliding hole, one end of the first snap-in pin 221 is movably inserted into the first sliding hole and abuts against the first return spring; a second sliding hole is provided at the other end of the first snap-in pin 221, a second return spring is provided in the second sliding hole, and one end of the second snap-in pin 222 is movably inserted into the second sliding hole and abuts against the second return spring. Preferably, two first sliding holes are symmetrically arranged on the base 22, and the two first sliding holes are located in the same radial direction; a first bayonet 221 is arranged in each first sliding hole, and a second bayonet 222 is arranged on each first bayonet 221; such an arrangement ensures reliable bayonet installation between the first purification layer 23 and the base 22, and the structure is more stable.

[0049] like Figure 5 As shown, in this embodiment, further, the snap-in groove includes a vertical groove 2331, a first inclined groove 2332, a second inclined groove 2333 and a third inclined groove 2334; the upper end of the vertical groove 2331 penetrates upwardly through the inner wall of the purification layer; one end of the first inclined groove 2332 is connected to the lower end of the vertical groove 2331, one end of the second inclined groove 2333 is connected to the other end of the first inclined groove 2332, and the second inclined groove 2333 and the third inclined groove 2334 are respectively connected to the vertical groove 2331; the third inclined groove 2334 is arranged at the groove bottom of the second inclined groove 2333, and the groove depth is greater than the groove depth of the second inclined groove 2333; a first step 2335 is arranged at the intersection of the lower end of the vertical groove 2331 and the first inclined groove 2332; a second step 2336 is arranged at the junction of the third inclined groove 2334 and the vertical groove 2331; a transition inclined surface 2337 is arranged in the first inclined groove 2332.

[0050] Specifically, during installation, the vertical slot 2331 on the first purification layer 23 is aligned with the position of the first bayonet 221, and then the first purification layer 23 is lifted upward, so that the first bayonet 221 and the second bayonet 222 are movably embedded in the vertical slot 2331, until the first bayonet 221 and the second bayonet 222 pass over the first step 2335 and enter the first inclined slot 2332. At this time, the first purification layer 23 is movably in contact with the first spring 214, and the first spring 214 is in a natural state. The first bayonet 221 cooperates with the first step 2335 to limit the purification device. At this time, the first purification layer 23 is in a locked state;

[0051] When replacement or maintenance is required, the purification component 2 is taken out from the first shell 1, and then the first purification layer 23 is pressed upward to compress the first spring 214. At this time, the first bayonet 221 and the second bayonet 222 move along the trajectory of the first inclined section, and move in the first inclined groove 2332 through the transition inclined surface 2337 until the first bayonet 221 is embedded in the second inclined groove 2333, and the second bayonet 222 is movably embedded in the third inclined groove 2334, thereby preventing the first bayonet 221 and the second bayonet 222 from retreating. Then the first bayonet 221 and the second bayonet 222 move along the trajectory of the third inclined groove 2334 until the first bayonet 221 and the second bayonet 222 return to the vertical groove 2331 after crossing the second step 2336. At this time, the first purification layer 23 can be pulled out for replacement or maintenance;

[0052] After the purification component 2 is taken out from the first housing 1, the second purification component 2 can be taken out from the first housing 1. The modular design is adopted in this way, which is convenient for replacement and maintenance and reduces the use cost.

[0053] like Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, a purification device of this embodiment, in some embodiments, the first purification layer 23 is provided with a first ratchet 234; the second purification layer 3 is provided with a second ratchet 33 opposite to the first ratchet 234; when the driving mechanism 4 rotates in the first direction, it engages with the first ratchet 234 for transmission; when the driving mechanism 4 rotates in the second direction, it engages with the second ratchet 33 for transmission.

[0054] Specifically, when the driving mechanism 4 rotates clockwise, the driving mechanism 4 engages with the first ratchet 234 for transmission, thereby driving the first purification layer 23 to rotate clockwise. When the driving mechanism 4 rotates counterclockwise, the driving mechanism 4 engages with the second ratchet 33 for transmission, thereby driving the second purification layer 3 to rotate counterclockwise, thereby realizing convenient selection of filter elements with different filtering effects between any two layers for superimposed filtration to improve the filtering efficiency and purification capacity.

[0055] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figures 7 to 9 As shown, a purification device of this embodiment, in some embodiments, the driving mechanism 4 includes a motor 41 and a turntable 42 connected to the output end of the motor 41; the turntable 42 is provided with at least one set of centrifugal transmission components; the turntable 42 is provided with a centrifugal guide groove 421 and a circular arc groove 422 connected to the outer end of the centrifugal guide groove 421 corresponding to each set of centrifugal transmission components, and both ends of the circular arc groove 422 are connected to the inwardly inclined limit groove 423;

[0056] The centrifugal transmission assembly includes a tension spring 431, a centrifugal slider 432 slidably arranged on the turntable 42, and a limiting bracket 433; the tension spring 431 is connected to the centrifugal slider 432 and the middle part of the turntable 42; the centrifugal slider 432 is provided with a sliding pin 4321, and the sliding pin 4321 is initially movably embedded in the centrifugal guide groove 421; the centrifugal slider 432 is slidably provided with a first pawl 434 and a second pawl 435 spaced up and down; the first pawl 434 and the second pawl 435 are respectively connected to the centrifugal slider 432 with a spring piece 436; the two ends of the limiting bracket 433 are respectively connected to the turntable 42 with a second spring 437, and the limiting bracket 433 is provided with a limiting opening 4331.

[0057] Specifically, when the motor 41 drives the turntable 42 to rotate clockwise at a high speed, the centrifugal slider 432 overcomes the pulling force of the tension spring 431 and slides outward under the action of centrifugal force, and the sliding pin 4321 moves along the trajectory of the centrifugal guide groove 421 until the sliding pin 4321 enters the arc groove 422 and the centrifugal slider 432 enters the limiting opening 4331. At this time, relative rotation occurs between the turntable 42 and the centrifugal slider 432, so that the sliding pin 4321 moves along the arc groove 422, and the second spring 437 on one side is compressed. The limiting bracket 433 follows the centrifugal slider 432 to slide offset under the action of the centrifugal slider 432 until the sliding pin 4321 enters the limiting groove 423 from the arc groove 422. At this time, the limiting groove 423 limits the sliding pin 4321, so that the centrifugal slider 432 remains in the current position. The ratchet direction is opposite to that of the first ratchet 434. Under the action of the spring piece 436, the first ratchet 434 maintains transmission engagement with the first ratchet 234. Then, the rotation speed of the turntable 42 is reduced to adjust the position of the first filter element 232. After the rotation speed is reduced, although the centrifugal force on the centrifugal slider 432 is reduced, the position of the centrifugal slider 432 is maintained due to the limitation of the limiting groove 423. At the same time, the limiting bracket 433 limits the rotational freedom of the centrifugal slider 432 through the limiting opening 4331, so that the first ratchet 434 and the first ratchet 234 are maintained in a meshing state, thereby stably realizing the power transmission between the turntable 42 and the first purification layer 23, so that the turntable 42 synchronously drives the first purification layer 23 to rotate, thereby realizing the adjustment of the position of the first filter element 232, and the first filter element 232 with the required filtering effect is selected to rotate to align with the position of the discharge port 11.

[0058] After the position is adjusted, the motor 41 stops rotating, the second spring 437 pushes the limit bracket 433 to reset, and the limit bracket 433 drives the centrifugal slider 432 to move, so that the sliding pin 4321 enters the arc groove 422 from the limit groove 423. When the sliding pin 4321 moves to a position corresponding to the centrifugal guide groove 421, the centrifugal slider 432 moves centripetally under the tension of the tension spring 431, and the sliding pin 4321 moves inward along the centrifugal guide groove 421, thereby realizing the reset of the centrifugal slider 432.

[0059] Similarly, when the motor 41 drives the turntable 42 to rotate counterclockwise at a high speed, the sliding pin 4321 enters the arc groove 422 through the centrifugal guide groove 421, and then enters the limit groove 423 on the other side, so that the second spring 437 is compressed. At this time, the second pawl 435 is driven and meshed with the second ratchet 33 of the second purification layer 3, thereby realizing power transmission between the turntable 42 and the second purification layer 3, so that the turntable 42 synchronously drives the second purification layer 3 to rotate, thereby adjusting the position of the second filter element 32, so that the second filter element 32 with the required filtering effect is selected to rotate to align with the position of the discharge port 11.

[0060] like Figure 2 , Figure 8 and Fig. 9 As shown, in some embodiments of a purification device of this embodiment, two groups of centrifugal transmission components are provided, and the two groups of centrifugal transmission components are symmetrically distributed on the turntable 42. In this embodiment, two groups of centrifugal transmission components are provided to realize power transmission between the turntable 42 and the first purification layer 23 or the second purification layer 3, so that the turntable 42 can stably and reliably drive the first purification layer 23 or the second purification layer 3 to rotate, so as to adjust the positions of the first filter element 232 and the second filter element 32.

In this embodiment, a plurality of first filter holes are provided on the first purification body 231 to facilitate the installation and replacement of the first filter element 232.
