Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, and in particular to a kitchen waste sorting and pulping device. Background Technology

[0002] Kitchen waste refers to easily perishable, easily spoiled and smelly waste generated in daily life.

[0003] For example, a patent application with publication number CN109909267B, published on March 1, 2017, entitled "A Method for Sorting and Pulping Kitchen Waste," describes a method for sorting and pulping kitchen waste, including a large-material separator and a fine pulping machine. The original kitchen waste is fed into the large-material separator, where the main shaft drives multiple sets of stripping conveyor blades to rotate at low speed, breaking up inert, large debris. Oil-water mixtures and organic matter are stripped and pushed towards the outlet. The sorted coarse slurry flows through a coarse steel screen into a coarse slurry storage bin, while inert debris is discharged from the large material outlet. A dual-cylinder slurry pump continuously transports the coarse slurry to the crushing chamber of the fine pulping machine. The crushing main shaft drives multiple sets of crushing blades to rotate at high speed, cutting and crushing the coarse slurry. The crushed slurry flows through a fine steel screen into a fine slurry storage bin, while lightweight fragments are ejected from the fragment outlet at the rear. This invention can effectively separate recalcitrant inert debris; however, the slag discharge efficiency needs improvement. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a kitchen waste sorting and pulping device to solve the problem of insufficient slag discharge efficiency.

[0005] To achieve the above objectives, the present invention provides a kitchen waste sorting and pulping device, comprising a support frame, a crusher mounted on the support frame, a drive unit mounted on the support frame, the drive unit being connected to and controlling the rotation of the crushing main shaft, multiple sets of conveying crushing components mounted on the crushing main shaft, each set of conveying crushing components including alloy hammer plates arranged at equal angles and inclined, a housing mounted on the support frame on the outside of the crushing main shaft, a crushing chamber accommodating the crushing main shaft within the housing, a discharge port communicating with the crushing chamber at the upper end of the housing, a screen at the lower part of the housing, a large slag opening on the side of the screen away from the discharge port of the drive unit, the large slag opening including an upper slag opening at the lower part of the housing.

[0006] Optionally, each set of conveying crushing components includes two adjacent convex plates connected to the crushing main shaft. Each convex plate has at least one protrusion, and the protrusions on adjacent convex plates are staggered. The alloy hammerhead plate is mounted on the protrusion on the convex plate via a rotating shaft.

[0007] Optionally, there may be a certain deflection angle between two adjacent conveying crushing components.

[0008] Optionally, the tilt angle of the alloy hammerhead plate gradually decreases along the conveying method.

[0009] Optionally, the rotating shaft is rotatably mounted on the convex plate, and a torsion spring is provided outside the rotating shaft. The two ends of the torsion spring are respectively connected to the alloy hammer plate and the convex plate. A protective sleeve is fitted outside the torsion spring, and both ends of the protective sleeve are connected to the rotating shaft through bearings.

[0010] Optionally, the size of the screen gradually decreases along the conveying direction.

[0011] Optionally, the housing includes a lower shell disposed on the support frame, and an upper cover is fitted onto the lower shell.

[0012] Optionally, the lower end face of the upper cover is provided with wear-resistant plates arranged at equal angles, and a wear-resistant strip is connected between two adjacent wear-resistant plates.

[0013] Optionally, a discharge hopper is provided under the lower shell, and a slurry inlet is provided on the discharge hopper below the screen. The large slag inlet also includes a slag outlet located below the upper slag outlet. The slag outlet is located on the side of the slurry inlet away from the discharge outlet. A partition plate is provided between the slag outlet and the slurry inlet, and the upper end of the partition plate abuts against the lower end of the lower shell.

[0014] Optionally, the driving component includes a crushing motor mounted on the support frame, and the output end of the crushing motor is connected to the crushing main shaft via a transmission.

[0015] The beneficial effects of this invention: This invention provides a kitchen waste sorting and pulping device. Waste enters the crushing chamber of a crusher through the feed inlet. The drive unit controls the rotation of the crushing main shaft, which drives the alloy hammer plate on the crushing main shaft to rotate and hammer and knock the waste. During the knocking process, the waste hits the inner wall of the crushing chamber, crushing some organic matter. However, there are still some fibers, garbage bags and other waste that are not easy to crush. The crushed waste becomes a slurry that can be discharged through the screen. Because the alloy hammer plate is inclined at a certain angle, it can push the waste that cannot be discharged through the screen forward. At the same time, during the high-speed rotation, lightweight objects are also pushed forward. Finally, the uncrushed material is discharged through the large slag outlet, which facilitates the pulping and slag discharge of the waste. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0024] like Figures 1 to 4As shown, a kitchen waste sorting and pulping device includes a support frame 10, on which a crusher 1 is mounted. The crusher 1 includes a drive unit mounted on the support frame 10. The drive unit is connected to a crushing spindle 3 and controls the rotation of the crushing spindle 3. The crushing spindle 3 is equipped with multiple sets of conveying crushing components. Each set of conveying crushing components includes alloy hammer plates 4 arranged at equal angles. The alloy hammer plates 4 are inclined. A housing mounted on the support frame 10 is provided on the outside of the crushing spindle 3. A crushing chamber is provided inside the housing to accommodate the crushing spindle 3. A feed port 11 communicating with the crushing chamber is provided at the upper end of the housing. A screen 6 is provided at the lower part of the housing. A large slag port 13 is provided on the side of the screen 6 away from the feed port 11 of the drive unit. The large slag port 13 includes an upper slag port provided at the lower part of the housing.

[0025] Waste enters the crushing chamber of the crusher 1 through the feed port 11. The drive unit controls the rotation of the crushing main shaft 3, which drives the alloy hammer plate 4 on the crushing main shaft 3 to rotate and hammer and knock the waste. During the knocking process, the waste hits the inner wall of the crushing chamber, crushing some organic matter. However, there are still some fibers, garbage bags and other waste that are not easy to crush. The crushed waste becomes a slurry that can be discharged through the screen 6. Since the alloy hammer plate 4 is inclined at a certain angle, it can push the waste that cannot be discharged through the screen 6 forward. At the same time, during the high-speed rotation, lightweight objects are also pushed forward. Finally, the uncrushed material is discharged through the large slag outlet 13, which facilitates the production of slurry and slag discharge. While producing a certain amount of slurry, slag can be discharged relatively quickly.

[0026] Each set of conveying crushing components includes two adjacent convex plates 14 connected to the crushing main shaft 3. Each convex plate 14 has at least one protrusion, and the protrusions on adjacent convex plates 14 are staggered. The alloy hammer plate 4 is mounted on the protrusion on the convex plate 14 via a rotating shaft 15.

[0027] There is a certain deflection angle between two adjacent conveying and crushing components. The smaller the deflection angle, the easier it is to convey. By controlling the deflection angle, the crushing time of the waste in the crushing chamber can be controlled, thereby improving the crushing quality of the waste.

[0028] The tilt angle of the alloy hammer plate 4 gradually decreases along the conveying method. When the initial tilt angle of the alloy hammer plate 4 is relatively large, the radial (perpendicular to the axial) component of the garbage's gravity increases, and more garbage tends to slide down the surface of the alloy hammer plate 4 rather than be pushed forward, which facilitates the crushing of the garbage. Subsequently, the alloy hammer plate 4 is arranged horizontally or at a small tilt angle. The smaller the tilt angle, the faster the conveying speed and the higher the conveying efficiency. The axial component of the garbage's gravity is larger, and the thrust of the alloy hammer plate 4 can more efficiently drive the garbage forward. The garbage that has not been crushed after a period of crushing is the garbage that is not easy to crush. This part of the garbage can be quickly transferred to the large slag outlet 13 for discharge, improving the crushing efficiency of the garbage.

[0029] The rotating shaft 15 is rotatably mounted on the convex plate 14. A torsion spring is provided outside the rotating shaft 15. The two ends of the torsion spring are respectively connected to the alloy hammer plate 4 and the convex plate 14. A protective sleeve is provided on the outside of the torsion spring. Both ends of the protective sleeve are connected to the rotating shaft 15 through bearings.

[0030] The size of the screen 6 gradually decreases along the conveying direction, which helps to reduce the amount of difficult-to-crush waste passing through the screen 6.

[0031] The housing includes a lower shell 5 disposed on the support frame 10, and an upper cover 7 is provided on the lower shell 5 to facilitate the detachable installation of the housing.

[0032] The lower end face of the upper cover 7 is provided with wear-resistant plates 9 arranged at equal angles. Wear-resistant strips 8 are connected between two adjacent wear-resistant plates 9. The rotation of the crushing main shaft 3 drives the alloy hammer plate 4 to knock the garbage. During the knocking process, the garbage hits the wear-resistant plates 9 and wear-resistant strips 8 on the top of the upper cover 7. The wear-resistant plates 9 and wear-resistant strips 8 are both made of alloy, which facilitates the crushing of organic matter in the garbage and improves the crushing efficiency.

[0033] The screen 6 is disposed on the lower shell 5.

[0034] The lower shell 5 is provided with a discharge hopper, and the discharge hopper is provided with a slurry inlet 12 located below the screen 6. The large slag inlet 13 also includes a slag outlet located below the upper slag inlet. The slag outlet is located on the side of the slurry inlet 12 away from the discharge outlet 11. A partition plate is provided between the slag outlet and the slurry inlet 12. The upper end of the partition plate is abutted against the lower end of the lower shell 5. The partition plate is located below the screen 6 and the upper slag inlet. The lower end face of the lower shell 5 is provided with a protruding groove that engages with the partition plate.

[0035] The driving component includes a crushing motor 2 mounted on the support frame 10. The output end of the crushing motor 2 is connected to the crushing spindle 3. When the crushing motor 2 starts, it drives the crushing spindle 3 to rotate. Through the inclined alloy hammer plate 4, the waste entering the crushing chamber from the feed port 11 moves towards the large slag port 13. At the same time, the alloy hammer plate 4 on the crushing spindle 3 crushes and slurries the waste. The slurry is discharged through the screen 6, while the slag is conveyed to the large slag port 13 by the rotation of the crushing spindle 3 and discharged through the large slag port 13.
