Specific embodiments

[0020] It is easy to understand that according to the technical solution of the present utility model, without changing the essence of the present utility model, those of ordinary skill in the art can propose various replaceable structural forms and implementation manners. Therefore, the following specific embodiments and the accompanying drawings are only exemplary illustrations of the technical solution of the present utility model, and should not be regarded as all of the present utility model or as a limitation or restriction on the technical solution of the present utility model.

[0021] Combined with an embodiment of the present utility model Figures 1 - 4 Shown as follows.

[0022] As Figure 1 shown, for the overall structure, a magnetic filtration structure includes: a cylinder body 1, both ends of the cylinder body 1 are fixedly communicated with a liquid inlet 2 and a liquid outlet 3, and first hoops 4 for communicating with external pipelines are fixedly arranged at the ends of the liquid inlet 2 and the liquid outlet 3. The inside of the cylinder body 1 is a cavity and the top is open, and the opening is sealed by a cover 5 with a corresponding structure. The edge of the cover 5 extends outwards with an annular platform 6 corresponding to the side of the top of the cylinder body 1. The annular platform 6 is covered with a second hoop 7, one end of the second hoop 7 is hinged and the other end is movably locked. A plurality of detachable filter water pipes 8 are fixedly arranged at the bottom of the cover 5. Each filter water pipe 8 is provided with small holes 9 on both sides corresponding to the liquid inlet 2 and the liquid outlet 3. Each filter water pipe 8 is filled with magnetic particles 10, and the diameter of the magnetic particles 10 is set to be larger than the diameter of the small holes 9.

[0023] As Figure 4 shown, in this embodiment, the filter water pipes 8 include five and are equidistantly distributed in a circumferential manner around the center of the inner bottom of the cover 5. The filter water pipes 8 are arranged at an interval from the inner bottom of the cylinder body 1, and the interval distance does not exceed 15 mm.

[0024] Furthermore, the first hoop 4 and the second hoop 7 have similar structures, and the inner diameters of the corresponding hoops respectively correspond to the cover 5, the liquid inlet 2, and the liquid outlet 3. Similarly, as Figure 1 and Figure 3As shown, the annular platform 6 has a trapezoidal structure. The first hoop 4 is recessed with a mating groove 11 corresponding to the annular platform 6. The annular platform 6 is embedded and fixed in the mating groove 11. The second hoop 7 and the corresponding liquid inlet 2 and liquid outlet 3 form the same mating groove 11 and annular platform 6 at the connection.

[0025] Taking the second hoop 7 as an example, in this embodiment, the second hoop 7 includes a first semi-circular ring 12, a second semi-circular ring 13, a limiting block 14 and a locking bolt 15. The first semi-circular ring 12 and the second semi-circular ring 13 are respectively formed with a notch and an extension platform 17 at the corresponding hinged ends. The extension platform 17 is placed on the notch and is rotatably connected to the bottom of the notch through a positioning shaft 21. The top surface of the extension platform 17 is flush with the top surface of the first semi-circular ring 12. The first semi-circular ring 12 and the second semi-circular ring 13 are both convex with a U-shaped groove 18 at the corresponding movable locking ends. The limiting block 14 is fixedly connected in the U-shaped groove 18 of the first semi-circular ring 12. The locking bolt 15 is rotatably connected in the U-shaped groove 18 of the second semi-circular ring 13. One end of its corresponding threaded shaft section is in threaded cooperation with the limiting block 14, and the other end is exposed outside the U-shaped groove 18 of the second semi-circular ring 13.

[0026] With the above structure, for the biological waste liquid to be processed, it can be correspondingly connected to the liquid inlet 2 and the liquid outlet 3 through an external hose and deployed into the corresponding water circuit. The connection is locked and sealed by the first hoop 4. Then, under the action of an external water pump or the like, the waste liquid enters from the liquid inlet 2 and starts filtering. The water flow direction is sent from the liquid inlet 2 to the liquid outlet 3.

[0027] During the filtering process, it is preliminarily screened by 5 filter tubes evenly distributed at equal intervals in the circumference. The small holes 9 opened at the corresponding liquid inlet and outlet 3 are used for preliminary filtering. This can also increase the residence time of the waste liquid in the cylinder 1 and ensure sufficient time for the magnetic adsorption process. Then, the waste liquid entering the filter tube is adsorbed by the pre-placed magnetic particles 10. Then, the magnetic impurities in the waste liquid are removed, and then it is sent out from the liquid outlet 3 for the next step of biological waste liquid treatment.

[0028] Furthermore, a butterfly-shaped handle 19 is fixed at one end of the locking bolt 15 exposed outside the U-shaped groove 18 of the second semi-circular ring 13. A U-shaped lifting rod 20 is also fixed on the top of the cover 5. When actually tightening each hoop, it can be easily rotated through the butterfly-shaped handle 19. Then, the locking bolt 15 continuously screws in or out along the preset threaded opening in the limiting block 14 to realize the tightening and loosening of the first hoop 4 or the second hoop 7, and ensure the connection and sealing at the cover 5, the liquid inlet 2, and the liquid outlet 3.

[0029] The technical scope of the present utility model is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present utility model, and these deformations and modifications should all fall within the protection scope of the present utility model.
