Specific implementation manner

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-6 , a sludge resource treatment tower provided by the present utility model includes a tank body 1. A servo motor 2 is fixed at the top of the tank body 1, and a rotating rod 3 is fixed at the output end of the servo motor 2. The rotating rod 3 is successively provided with a first mounting port 4 and a second mounting port 5 from bottom to top, and a first reset mechanism and a reset stirring mechanism are respectively arranged at the first mounting port 4 and the second mounting port 5. An annular grinding disc 7 is fixed on the inner side wall of the tank body 1, and a conical baffle 8 is fixed on the top of the annular grinding disc 7. The conical baffle 8 serves to limit fine filter residues to the gap between the conical grinding disc 6 and the annular grinding disc 7;

[0024] A first filter screen 9 and a conical grinding disc 6 are successively sleeved on the rotating rod 3 from top to bottom, and a pushing mechanism for pushing the first filter screen 9 and the conical grinding disc 6 to vibrate is arranged between the first filter screen 9 and the conical grinding disc 6. The conical grinding disc 6 and the annular grinding disc 7 serve to grind the filter residues;

[0025] The side wall of the first filter screen 9 is provided with symmetrically distributed second reset mechanisms. The inner wall of the tank body 1 is fixed with a second filter screen 12, and the bottom end of the rotating rod 3 is rotatably connected to the top of the second filter screen 12. The first filter screen 9 can facilitate the filtration of fine filter residues. The bottom end of the rotating rod 3 is also equipped with an inclined scraper 11 to prevent the surface of the second filter screen 12 from accumulating and blocking the mesh holes, and the second filter screen 12 filters out finer powdery sludge;

[0026] The side wall of the tank body 1 is provided with a discharge port 15, and the top of the tank body 1 is respectively provided with a feed port 13 and an exhaust port 14. The exhaust port 14 serves to discharge high-temperature water vapor;

[0027] The pushing mechanism includes three first bumps 1002 fixed to the bottom of the first filter screen 9 and distributed in a circular array. The top of the conical grinding disc 6 is fixed with three second bumps 1001 distributed in a circular array. The collision between the first bumps 1002 and the second bumps 1001 forms repeated vibrations;

[0028] The first reset mechanism includes a sliding plate 1601 and a first spring 1602 respectively inserted into the first mounting opening 4, and both ends of the first spring 1602 are respectively fixed to the opposite side walls of the sliding plate 1601 and the first mounting opening 4. Both ends of the sliding plate 1601 are fixed to the inner side wall of the conical grinding disc 6. The sliding plate 1601 vibrates repeatedly under the action of the first spring 1602, driving the conical grinding disc 6 to vibrate repeatedly;

[0029] The reset stirring mechanism includes a moving plate 1802 and a second spring 1801 respectively inserted into the second mounting opening 5, and both ends of the second spring 1801 are respectively fixed to the opposite side walls of the second mounting opening 5 and the moving plate 1802. Symmetrically distributed inclined scrapers 11 are fixed to both side walls of the moving plate 1802, and a heating mechanism is provided inside the inclined scrapers 11. Under the action of the second spring 1801, the moving plate 1802 presses the inclined scrapers 11 against the surfaces of the first filter screen 9 and the second filter screen 12 all the time to clean the surfaces;

[0030] The heating mechanism includes a heating groove 1902 opened on the side wall of the inclined scraper 11, and an electric heating wire 1901 is installed in the heating groove 1902. The electric heating wire 1901 can directly heat the inclined scraper 11, so that the filter residues and powdery sludge can be directly and evenly heated;

[0031] The second reset mechanism includes two sliding grooves 1701 opened on the opposite side walls of the tank body 1, and a slider 1702 and a third spring 1703 are respectively inserted into the two sliding grooves 1701. Both ends of the third spring 1703 are respectively fixed to the opposite side walls of the slider 1702 and the sliding groove 1701, and the first filter screen 9 is fixed to the opposite side walls of the two sliders 1702. The slider 1702 vibrates repeatedly under the action of the third spring 1703, driving the first filter screen 9 to vibrate repeatedly.

[0032] Working principle: When in use, the filter residue of the sludge is introduced into the tank body 1 from the feed port 13. The filter residue will be stacked on the top of the first filter screen 9. The servo motor 2 drives the rotating rod 3 to rotate, driving the inclined scraper 11 to rotate, breaking up the filter residue. Small particles are separated out from the first filter screen 9, and large particles remain on the top of the first filter screen 9. At the same time, under the elastic action of the third spring 1703, the slider 1702 drives the inclined scraper 11 to rotate rapidly on the tops of the first filter screen 9 and the second filter screen 12, which not only plays a role in stirring and breaking up, but also prevents the surface of the first filter screen 9 and the second filter screen 12 from being blocked by the accumulated materials, improving the filtration efficiency. The second filter screen 12 can separate out the more powdery sludge needed from the mesh holes, realizing the screening of the powdery sludge. Moreover, the electric heating wire 1901 can directly heat the inclined scraper 11, enabling the filter residue and the powdery sludge to be directly and evenly heated, quickly evaporating the moisture in the filter residue and the powdery sludge, and facilitating the obtaining of dry powdery sludge;

[0033] When the rotating rod 3 rotates, it will simultaneously drive the sliding plate 1601 inserted in the first mounting port 4 to rotate, so that the conical grinding disc 6 fixed to the sliding plate 1601 can rotate, quickly grinding the fine filter residue accumulated on the tops of the conical grinding disc 6 and the annular grinding disc 7. The conical baffle 8 serves to limit the fine filter residue to the gap between the conical grinding disc 6 and the annular grinding disc 7. At the same time, the rotation of the conical grinding disc 6 drives the second convex block 1001 to rotate. When it encounters the first convex block 1002 at the bottom of the first filter screen 9, the first filter screen 9 and the conical grinding disc 6 will be pushed, thereby repeatedly squeezing the first spring 1602 and the third spring 1703 respectively, enabling the first filter screen 9 and the conical grinding disc 6 to vibrate repeatedly. The repeated vibration screening of the first filter screen 9 can facilitate the rapid separation of the fine filter residue from the mesh holes, improving the filtration efficiency of the first filter screen 9. And the up-and-down repeated movement of the conical grinding disc 6 can add vertical grinding during the rotational grinding, quickly grinding the fine filter residue into powder and improving the grinding effect.
