[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: during the recycling and processing of feces, the mixture contains a lot of impurities, and existing feces solid-liquid separation and recycling devices are not convenient for pre-treating the impurities, which can easily lead to equipment damage or blockage. Utility Model Content

[0005] The purpose of this invention is to provide a fecal recycling processor with solid-liquid separation function to solve the problem in the above-mentioned fecal solid-liquid separation and recycling device that is not convenient to pre-treat the impurities in the device, which can easily lead to equipment damage or blockage.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fecal recycling processor with solid-liquid separation function, comprising a shell, a feeding hopper fixedly connected to one side of the top of the shell, and a separation structure installed inside the shell;

[0007] The separation structure includes two drive rollers rotatably connected inside the housing, and the drive rollers are provided with equally spaced mounting grooves on their outer sides. The two drive rollers are rotatably connected to the outer sides through the mounting grooves, and the drive rollers are equally spaced between the drive rollers to form a mesh filter structure. The drive rollers are driven by a motor.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1 - Figure 6This utility model provides the following technical solution: a fecal recycling processor with solid-liquid separation function, including a shell 1, a feeding hopper 2 fixedly connected to one side of the top of the shell 1, and a separation structure installed inside the shell 1; the separation structure includes two drive rollers 3 rotatably connected inside the shell 1, and the outer sides of the drive rollers 3 are provided with equally spaced mounting grooves 4, the outer sides of the two drive rollers 3 are rotatably connected to the drive rollers 3 through the mounting grooves 4, and the drive rollers 5 are equally spaced between the drive rollers 3 to form a mesh filter structure, and the drive rollers 3 are driven by a motor; the top of the shell 1 is provided as a sloping structure inclined downward toward the feeding hopper 2, and the installation height of the drive roller 3 closer to the feeding hopper 2 is lower than that of the other drive roller 3. The transmission ropes 5 installed on the outer sides of the two drive rollers 3 form a slope facing the feed hopper 2; the filling blocks 6 are fixedly connected to both sides inside the outer shell 1, and the filling blocks 6 are in contact with both sides of the drive rollers 3 and both sides of the transmission ropes 5. The outer shell 1 is provided with a first discharge port 7 on the side away from the feed hopper 2; a scraper 8 is fixedly connected to one end of the filling block 6 near the first discharge port 7, and the scraper 8 is provided with equidistant guide holes 9 inside, and each transmission rope 5 is slidably connected inside the guide hole 9; a baffle 10 is fixedly connected to one end of the filling block 6 near the feed hopper 2, and the baffle 10 is provided with equidistant guide holes 9 at both the upper and lower ends inside, and the transmission ropes 5 are slidably connected inside the baffle 10 through the guide holes 9.

[0027] In operation, the operator first feeds the feces and solidifying agent into the outer casing 1 through the feed hopper 2. The mixture falls directly onto the drive rope 5 through the feed hopper 2. At this time, the motor drives the drive roller 3 to rotate, and the drive roller 3 drives the outer drive rope 5 to rotate through the mounting groove 4 during rotation. During its rotation, the drive rope 5 guides the mixture to move along the slope inside the outer casing 1. Because the drive rope 5 is inclined towards the feed hopper 2, the moisture in the mixture flows down into the gap as the mixture moves on the drive rope 5, entering the collection area. The drive rope 5 acts as a mesh filter structure, effectively performing preliminary filtration of the mixture, extracting most of the moisture, while solid matter accumulates at the top of the drive rope 5. After a period of time, these solid residues are gradually pushed into the first discharge port 7 by the movement of the drive rope 5, thus being discharged from the outer casing 1.

[0028] As the drive rope 5 continues to move, when it slides through the guide hole 9 inside the scraper 8, the debris attached to the outside of the drive rope 5 will be scraped off by the scraper 8. The scraper 8 will then discharge the scraped debris through the first discharge port 7, ensuring the cleanliness of the equipment and the proper functioning of the filter.

[0029] Example 2: Based on Example 1, the following structure is also disclosed: A water collection tank 11 is fixedly connected to the lower inner side of the outer shell 1, and a cylindrical filter screen 12 is fixedly connected to the end of the water collection tank 11. A second discharge port 14 is provided at the end of the cylindrical filter screen 12 away from the water collection tank 11, and a drainage trough 13 is provided at the lower end of the water collection tank 11 and the cylindrical filter screen 12. The drainage trough 13 is connected to the outside through a pipe. A drive shaft is rotatably connected inside the water collection tank 11 and the cylindrical filter screen 12. The drive shaft is driven by a motor. The drive shaft is composed of a mixing section 15 and an extrusion section 16. The mixing section 15 is located inside the water collection tank 11, and the extrusion section 16 is located inside the cylindrical filter screen 12. Drive bars 17 distributed in a spiral structure are fixedly connected to the outside of the extrusion section 16 and the mixing section 15. The density of the drive bars 17 located outside the extrusion section 16 is greater than that of the drive bars 17 located outside the mixing section 15. The extrusion section 16 is designed as a frustum-shaped structure.

[0030] A drive shaft, driven by a motor, is rotatably connected inside the water collection tank 11 and the cylindrical filter screen 12. The drive shaft is divided into a mixing section 15 and a pressing section 16. The mixing section 15, located inside the water collection tank 11, is mainly used for mixing and stirring, while the pressing section 16, located inside the cylindrical filter screen 12, is mainly used for pressing the solid-liquid mixture. Drive bars 17, arranged in a spiral structure, are fixedly connected to the outside of the drive shaft. The drive bars 17 on the outer side of the pressing section 16 have a higher density, while those on the outer side of the mixing section 15 have a relatively lower density. This design allows for higher pressure to be generated at the pressing section 16, thereby achieving more efficient solid-liquid separation.

[0031] When the pre-filtered liquid enters the collection tank 11, the motor starts driving the drive shaft to rotate. At this time, the mixing section 15 and the extrusion section 16 rotate within the collection tank 11 and the cylindrical filter screen 12, respectively. Inside the cylindrical filter screen 12, the drive bar 17 on the outside of the mixing section 15 agitates the liquid and solidifying agent, ensuring thorough mixing. The rotation of the drive bar 17 also moves the solid-liquid mixture towards the second discharge port 14.

[0032] As the solid-liquid mixture moves along the second discharge port 14, it is compressed due to the increased density of the drive strips 17 on the outer side of the extrusion section 16. The frustum-shaped structure formed around the extrusion section 16 compresses the solid-liquid mixture against the inner wall of the cylindrical filter screen 12, thereby separating the solid from the liquid. The squeezed-out water is filtered through the cylindrical filter screen 12 and eventually flows into the drainage trough 13 to be discharged from the outer casing 1, while the solid residue is driven by the extrusion section 16 to the discharge section of the second discharge port 14.

For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
