It has good evaporation effect, can perform high-temperature maturation and sterilization treatment, accelerate the decomposition of organic matter, shorten the maturation time, increase steam utilization rate, save energy and protect the environment, and recycle water resources.

[0014] With the above structure, before maturation, the staff adds high-temperature decomposition bacteria into the horizontal mixer, and the telescopic end of the electric push rod three drives the closing plate one to move, opening the entrance, allowing the solid slag to fall from the drop hopper to the feed hopper and enter the horizontal mixer from the feed hopper. The entrance is then closed to form a closed internal environment of the horizontal mixer, and the steam output by the evaporation mechanism continues to enter the horizontal mixer.

The right-angle commutator 2 34 are both transmission-connected to the screw rod 32.

[0050] In this embodiment, the output shaft of the drive motor 2 31 drives the input shaft of the right-angle commutator 3 36 to rotate, the input shaft of the right-angle commutator 3 36 drives the two output shafts of the right-angle commutator 3 36 to rotate, the two output shafts of the right-angle commutator 3 36 respectively drive the input shafts of the right-angle commutator 1 33 at the corresponding positions of the two transmission groups to rotate, the input shaft of the right-angle commutator 1 33 drives the two output shafts of the right-angle commutator 1 33 at the corresponding positions to rotate, the two output shafts of the right-angle commutator 1 33 respectively drive the input shafts of the two right-angle commutator 2 34 at the corresponding positions to rotate, and the input shafts of the two right-angle commutator 2 34 respectively drive the screw rods 32 at the corresponding positions to rotate.

[0051] The scraper assembly includes a connecting rod 47, and sliders 48 are provided at both ends of the connecting rod 47. The two sliders 48 are respectively slidably set in two slide grooves 44 at corresponding positions on the same side of the two fixed plates 42.

The two screw rods 32 at corresponding positions of the transmission group on the same side are respectively rotatably set on the two sliders 48 of the scraper assembly away from the heat transfer plate 40.

[0052] In this embodiment, the two screw rods 32 of the transmission group rotate to drive the two sliders 48 at the corresponding positions of the scraper assembly near the heat transfer plate 40 on the same side to slide in the corresponding position of the second slide groove 44. The two sliders 48 drive the connecting rod 47 and a plurality of clamping plates 46 to move. When the clamping plates 46 move, they abut against the adjacent evaporation plates 45. When moving, the plurality of clamping plates 46 scrape off the scale generated by evaporation on the evaporation plates 45, thereby preventing excessive scale from affecting the evaporation efficiency.

[0053] The working principle of the present invention is as follows: the staff intermittently passes the livestock sewage into the primary filtering mechanism 8, and the primary filtering mechanism 8 filters the livestock sewage, that is, it is preliminarily filtered through the T-type filter 19 to preliminarily filter out large particles of solid residues. The filtered treated sewage is filtered again through the filter mesh, and the filtered treated sewage flows into the drain pipe 24 through the conical drainage bucket 23, and flows into the mixing barrel 11 through the drain pipe 24. After the filtration is completed, the large particles of solid residues are transported to the stirring and maturing mechanism 1, that is, the telescopic ends of the two electric push rods 21 drive the door closing plate 38 to slide in the two slide grooves to make the door closing plate 38 rise, and the telescopic ends of the two electric push rods 6 49 drive the opening and closing plate to move, so that the opening and closing plate is opened, and then the telescopic ends of the two electric push rods 18 drive the flip The shell 20 moves, and the flip shell 20 drives the filter screen and the T-type filter screen 19 to move. The flip shell 20 moves and tilts, so that the solid residue on the filter screen and the T-type filter screen 19 slides into the drop hopper 22, and falls from the drop hopper 22 into the feed hopper 26. The sewage filtered by the primary filtering mechanism 8 is transported to the sedimentation filtering mechanism 3, and the sedimentation filtering mechanism 3 stirs and precipitates the primary sewage to precipitate the small particles in the primary sewage, and filters and separates after the sedimentation treatment. The filtered sediment is discharged into the collecting box 4, that is, the filtered sewage is transported to the stirring barrel 11, and the two liquid medicine barrels 16 inject a certain amount of precipitation liquid into the stirring barrel 11. The output shaft of the driving motor 15 drives the stirring rod 9 to move, and the stirring rod 9 stirs the precipitation liquid The mixed liquid with sewage is fully mixed, condensed and precipitated to remove small suspended particles in the sewage. During the stirring and sedimentation process, the conical filter 50 filters the mixed liquid. After stirring and sedimentation, the electric butterfly valve 13 is opened, and the sediment is transported to the collection box 4 through the sewage pipe 14 to be collected. After the collection is completed, the staff will transport the collected sediment to the stirring and maturing mechanism 1. The water after precipitation and filtration is transported to the evaporation mechanism 5 through the pipeline. Steam is obtained after evaporation by the evaporation mechanism 5. That is, the water after precipitation and filtration flows into the evaporation zone directly from the two liquid inlet pipes 39. The fixed plate 42 protrudes from the upper and lower ends of the heat transfer plate 40, and cooperates with the heat insulation plate and the other two scraper assemblies to make the evaporation zone a closed space. The other two scraper assemblies After the movement of the components, the space is opened, and the evaporation blades 45 increase the contact area between the water and the hot surface. When evaporating water, the telescopic end of the electric push rod 5 30 drives the connecting frame to make intermittent movement, and the connecting frame drives the other two scraper assemblies to make intermittent movement, thereby intermittently releasing the steam generated in the upper and lower evaporation areas during evaporation, so that the steam is transported from the two outlet pipes 37 to the cooling water barrel 6 and the horizontal mixer 25. After evaporation is completed, the telescopic end of the electric push rod 5 30 drives the connecting frame to retract, and the connecting frame drives the other two scraper assemblies to retract, thereby releasing the seal of the two evaporation areas. After evaporation is completed, the transmission mechanism 7 cooperates with the evaporation mechanism 5 to scrape off the scale generated by evaporation, that is, the output shaft of the drive motor 2 31 drives the input shaft of the right-angle commutator 3 36 to rotate.The input shaft of the right-angle commutator 3 36 drives the two output shafts of the right-angle commutator 3 36 to rotate. The two output shafts of the right-angle commutator 3 36 respectively drive the input shafts of the right-angle commutator 1 33 at the corresponding positions of the two transmission groups to rotate. The input shaft of the right-angle commutator 1 33 drives the two output shafts of the right-angle commutator 1 33 at the corresponding positions to rotate. The two output shafts of the right-angle commutator 1 33 respectively drive the input shafts of the two right-angle commutator 2 34 at the corresponding positions to rotate. The input shafts of the two right-angle commutator 2 34 respectively drive the screw rods 32 at the corresponding positions to rotate. The four screw rods 32 of the two transmission groups respectively drive the scraper assemblies at the corresponding positions to move. The two scraper assemblies away from the heat transfer plate 40 slide on the corresponding slide grooves 2 44. When the scraper assembly slides, it scrapes off the scale on the evaporation sheets 45 at the upper and lower ends of the heat transfer plate 40. That is, the two screw rods 32 of the transmission group rotate to drive the two sliders 48 at the corresponding positions of the scraper assembly on the same side close to the heat transfer plate 40 to slide in the corresponding position of the slide groove 2 44. The two sliders 48 drive the connecting rod 47 and the several clamping plates 46 to move. When the clamping plates 46 move, they abut against the adjacent evaporation sheets 45. When moving, the several clamping plates 46 scrape off the scale generated by evaporation on the evaporation sheets 45, preventing the evaporation sheets from scaling and reducing the evaporation efficiency. The scraped scale is pushed to the discharge port, discharged from the discharge port, and collected by the staff. The steam is respectively transported to the cooling water bucket 6 and the stirring and aging mechanism 1, and high The thermolytic bacteria steam is introduced into the stirring and maturing mechanism 1 to heat the stirring and maturing mechanism 1 and perform high-temperature sterilization on the solid residue inside the stirring and maturing mechanism 1. That is, before maturation, the staff adds the thermolytic bacteria into the horizontal mixer 25. The telescopic end of the electric push rod 3 27 drives the closing plate 1 to move, opens the entrance, and allows the solid residue to fall from the drop hopper 22 to the feed hopper 26 and enter the horizontal mixer 25 from the feed hopper 26. Then, the entrance is closed to form a closed internal environment of the horizontal mixer 25, and the steam output by the evaporation mechanism 5 continues to enter the horizontal mixer 25. The horizontal mixer 25 stirs the solid residue and thermolytic bacteria that have entered, and inactivates them through high-temperature steam, which can completely kill the Escherichia coli in the feces. , parasite eggs and weed seeds, playing the role of sterilization, maturation and fermentation, and accelerating the decomposition of organic matter through high-temperature bacteria, quickly degrading malodorous substances such as hydrogen sulfide and ammonia, quickly deodorizing, shortening the maturation cycle, and completing the maturation to form organic fertilizer. The telescopic end of the electric push rod 4 29 drives the closing plate 2 to move, opening the discharge pipe 28, so that the organic fertilizer is output to the conveyor 2 and output through the conveyor 2, accelerating the closed maturation speed. The organic fertilizer formed by maturation is discharged to the conveyor 2 and transported out through the conveyor 2. The cooling water barrel 6 cools the steam to obtain distilled water. After completing the sewage treatment, the water in the cooling water barrel 6 is sucked by an external water pump to flush the sedimentation filter mechanism 3 and the primary filter mechanism 8, thereby extending the service life of the device.

[0054] In summary, the primary filtering mechanism 8 intercepts and filters large particles, and the sedimentation filtering mechanism 3 precipitates and filters small suspended particles, performing multi-stage solid-liquid separation to efficiently treat livestock wastewater;

[0055] The evaporation mechanism 5 cooperates with the transmission mechanism 7 to quickly evaporate the water after sedimentation and filtration, and clean the scale after evaporation, with good evaporation effect;

[0056] By transporting the steam generated by the evaporation mechanism 5 to the stirring and maturing mechanism 1, the stirring and maturing mechanism 1 performs high-temperature maturation and sterilization treatment on the sewage solid residue, accelerating the decomposition of organic matter, shortening the maturation time, increasing the steam utilization rate, and saving energy and protecting the environment;

[0057] By transporting the steam generated by the evaporation mechanism 5 to the cooling water barrel 6, distilled water is collected. The water has high purity after evaporation treatment, and cooperates with an external water pump to suck the water in the cooling water barrel 6 and flush the primary filter mechanism 8 and the sedimentation filter mechanism 3, thereby recycling water resources.
