[0025] like Figure 1-5 As shown, a filtering and slag discharge machine comprises a frame 1, on which a filtering mechanism is arranged, and a slag discharge mechanism is connected to the bottom of the filtering mechanism, the filtering mechanism comprises a filtering shell 2, and the upper and lower parts of the side walls of the filtering shell 2 are respectively provided with a feed port 3 and a liquid outlet 4, a slag outlet 5 is provided at the bottom of the filtering shell 2, a cylindrical filtering screen 6 is arranged in the filtering shell 2, and the upper and lower ends of the filtering screen 6 are both open in design, and the top outer wall and the bottom outer wall of the filtering screen 6 are respectively fixedly connected to the inner wall of the filtering shell 2 by an upper connecting ring 7 and a lower connecting ring 8, and a cleaning gap is left between the filtering screen 6 and the filtering shell 2, a rotating shaft 9 is arranged in the filtering screen 6, and the top of the rotating shaft 9 extends upward through the top wall of the filtering shell 2 and is connected to a first driving member 10, and the first driving member 10 is installed on the top surface of the top wall, and a plurality of scrapers are fixedly arranged on the outer wall of the rotating shaft 9, and the scrapers are against the inner wall of the filtering screen 6, wherein the first driving member 10 is a driving motor.

[0026] In this embodiment, the mixed liquid to be separated enters the filter screen 6 of the filter housing 2 through the feed port 3, and the first driving member 10 drives the rotating shaft 9 and the scraper to rotate, so that the mixed liquid is separated by the filter screen 6 under the action of centrifugal force, and then discharged from the liquid outlet 4. The filter residue sticks to the inner wall of the filter screen 6, and the filter residue is scraped off from the inner wall of the filter screen 6 by the rotation of the scraper, and then enters the slag discharge mechanism through the slag outlet 5.

[0027] A cleaning assembly is mounted on the upper connecting ring 7, and the cleaning assembly is located outside the filter 6. The cleaning assembly includes a rotating ring 11 rotatably connected to the upper connecting ring 7, and the upper connecting ring 7 is coaxially arranged with the rotating ring 11. Specifically, the two side walls of the rotating ring 11 are respectively provided with annular ridges, and the side walls of the upper connecting ring 7 connected with the rotating ring 11 are both provided with annular grooves, and the annular ridges are slidably connected in the annular grooves, so that the rotating ring 11 can rotate in the upper connecting ring 7. The top of the rotating ring 11 is fixedly connected with a column 12, and the column 12 is fixedly connected to the rotating shaft 9 through a cross bar 13. The bottom surface of the upper connecting ring 7 is rotatably connected with a longitudinal rod 14, and the upper outer wall of the longitudinal rod 14 is fixedly sleeved with a first gear 15, and the bottom surface of the upper connecting ring 7 is fixedly provided with a coaxial second gear 16, and the tooth groove of the outer wall of the first gear 15 is meshed with the tooth groove of the inner wall of the second gear 16. The outer wall of the longitudinal rod 14 is provided with a brush, and the brush contacts the outer wall of the filter 6.

[0028] In this embodiment, when the first driving member 10 drives the rotating shaft 9 to rotate, the column 12 connected to the cross bar 13 is driven to rotate, so that the rotating ring 11 rotates in the upper connecting ring 7, and then the longitudinal rod 14 rotates around the circumference of the filter screen 6. Since the first gear 15 is fixedly provided on the upper outer wall of the longitudinal rod 14, and the first gear 15 and the second gear 16 are engaged with each other during the rotation of the longitudinal rod 14 around the filter screen 6, the first gear 15 rotates. Therefore, the longitudinal rod 14 rotates while rotating around the filter screen 6, so that the brush cleans the outer wall of the filter screen 6.

[0029] Specifically, the slag discharge mechanism includes a slag discharge shell 18, which is fixedly mounted on the lower part of the frame 1. A slag inlet 19 is provided on the top of the slag discharge shell 18, and the slag inlet 19 is communicated with the slag outlet 5. A slag discharge screw 20 is provided in the slag discharge shell 18, and one end of the slag discharge screw 20 is transmission-connected to the output end of the second driving member 21. The second driving member 21 is fixedly mounted on one end of the slag discharge shell 18. A filter residue outlet 22 is provided on the top of the end of the slag discharge shell 18 away from the second driving member 21, and a filtrate outlet 23 is provided at the bottom of the slag discharge shell 18. The second driving member 21 is a driving motor.

[0030] The filter residue scraped off from the inner wall of the filter screen 6 falls into the slag discharge shell 18 through the slag inlet 19, and then the slag discharge screw 20 is driven to rotate by the second driving member 21 to transport the filter residue from the slag inlet 19 to the filter residue outlet 22, and is discharged from the filter residue outlet 22, and the filtrate reflux flows out from the filtrate outlet 23.

[0031] Specifically, the slag discharge screw 20 is a variable diameter and variable pitch mechanism, the end close to the slag inlet 19 is the feed end, and the end close to the filter residue outlet 22 is the discharge end. The pitch of the slag discharge screw 20 gradually decreases from the feed end to the discharge end, and the diameter of the slag discharge screw 20 gradually decreases from the feed end to the discharge end.

[0032] Since part of the filtrate is still mixed in the filter residue, the filtrate in the filter residue can be further squeezed by providing a variable diameter and variable pitch mechanism, so that the filtrate is discharged through the filtrate outlet 23, so that the moisture content of the final filter residue is lower.

[0033] Specifically, the filtrate outlet 23 is connected to the inlet of the water pump 24 through a pipeline, and the outlet of the water pump 24 is connected to the feed port 3 through a pipeline, so that the filtrate squeezed out of the slag discharge mechanism enters the filtering mechanism again for filtration.

[0034] Specifically, the feed port 3 is eccentrically arranged, and a guide plate 25 is provided at the feed port 3, and the guide plate 25 is fixedly connected to the inner wall of the filter housing 2. The feed port 3 is eccentrically arranged and the guide plate 25 is provided, so that the mixed liquid can be easily screwed into the filter screen 6 in the filter housing 2, so that the mixed liquid can enter more stably, thereby making the equipment run more stably. A slag separation net 26 is provided at the liquid outlet 4. Since the cleaning component scrapes off the filter residue on the outer wall of the filter screen 6, the filtrate mixed with a small amount of filter residue can be blocked by the slag separation net 26 when passing through the liquid outlet 4, so that the filtrate and the filter residue are separated more thoroughly.

[0035] Specifically, an electric control box 17 is disposed on the frame 1 , and the electric control box 17 is electrically connected to the first driving member 10 , the second driving member 21 and the water pump 24 .

[0036] The working principle of the utility model is as follows: by setting a filtering mechanism, the mixed liquid to be separated enters the filter housing 2 from the feed port 3, and the first driving member 10 drives the rotating shaft 9 and the scraper to rotate, so that the mixed liquid is separated by the filter screen 6 and discharged from the liquid outlet 4 under the action of centrifugal force, and the filter residue is attached to the inner wall of the filter screen 6, and the filter residue is scraped off from the inner wall of the filter screen 6 by the rotation of the scraper, and then enters the residue discharge mechanism through the residue outlet 5. During the filtering process, the rotating shaft 9 rotates, driving the rotating ring 11 to rotate in the upper connecting ring 7, thereby driving the longitudinal rod 14 to rotate around the circumference of the filter screen 6, and at the same time The first gear 15 is meshed with the second gear 16 to rotate the first gear 15, driving the longitudinal rod 14 to rotate, thereby cleaning the outer wall of the filter screen 6; the second driving member 21 drives the slag discharge screw 20 to rotate, and the filter residue is discharged from the filter residue outlet 22. During the rotation of the slag discharge screw 20, the filter residue is squeezed by the slag discharge screw 20 with a variable diameter and variable pitch, so that the filtrate in the filter residue is further squeezed out, and the filtrate flows from the filtrate outlet 23 through the pipeline to the feed port 3 for re-filtration. Finally, the filter residue in the slag discharge mechanism is discharged from the filter residue outlet 22, so that the moisture content of the final filter residue is lower.

[0037] The filtering and slag discharge machine provided by the utility model is provided with a cleaning component, so that during the rotation of the rotating shaft 9, the longitudinal rod 14 is driven by the cross bar 13, the column 12 and the rotating ring 11 to rotate along the circumferential direction of the filter screen 6. At the same time, the first gear 15 on the upper part of the longitudinal rod 14 is meshed with the second gear 16 of the upper connecting ring 7, so that the first gear 15 rotates, and then the longitudinal rod 14 rotates with the first gear 15. Therefore, during the rotation of the rotating shaft 9, the outer wall of the filter screen 6 can be cleaned by the rotation of the cleaning component to prevent the outer wall of the filter screen 6 from being clogged by long-term adhesion of filter residues, thereby improving the filtering effect.

[0038] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
