Description

Technical Field

[0001] This application relates to the technical field of kitchen waste treatment, and particularly relates to a kitchen waste sorting and pulping device. Background Art

[0002] Kitchen waste is domestic waste formed during the process of residents' living consumption. The main components of kitchen waste include food residues, and kitchen waste often contains a large amount of grease. Kitchen waste needs to be treated in a timely manner, otherwise it is extremely easy to rot and deteriorate, emit a foul smell, and spread bacteria and viruses.

[0003] In view of the above related technologies, for the treatment of kitchen waste at present, generally through a pulping device, centralized treatment of kitchen waste is carried out. For example, the existing kitchen waste feeding, pulping, pre-treatment and sorting device with the application number CN202221950608.7 belongs to the technical field of kitchen waste treatment. It includes a sorting component and a grasping component. The sorting component includes a large residue sorter and a primary sedimentation tank. The large residue sorter is used to screen solid substances in the material body. The primary sedimentation tank is connected to the large residue sorter. The primary sedimentation tank is used to precipitate and separate solid substances in the material body. The grasping component is arranged on the primary sedimentation tank. The grasping component is used to grasp suspended substances in the material body in the primary sedimentation tank. Kitchen waste is put into the large residue sorter. The large residue sorter screens out larger solid substances. The remaining material body enters the primary sedimentation tank. During the entry process, larger or heavier solid substances fall under the action of their own gravity. If there are still solid substances suspended on the upper layer of the material body, the grasping component is activated to grasp them and separate them from the material body, reducing the process of manual picking and improving the automation degree of sorting and pulping pre-treatment.

[0004] In the above-mentioned existing technology, through the grasping component, the solids inside the sedimentation tank are grasped, reducing the manual picking process and improving the automation degree of garbage treatment. However, the effective separation rate of organic matter and impurities is relatively low, which is likely to affect the efficiency of the overall treatment process. At the same time, there is a problem of solid garbage remaining in the grasping treatment, resulting in the relatively easy occurrence of equipment blockage, wear and other situations in the subsequent process.

In the present application, a food waste sorting and pulping system is formed by setting a hydraulic pulping machine, a slag-lifting screw receiving bin, a slag discharging screw conveyor, a screw extruder, an impurity temporary storage box and a leachate buffer box. Among them, the hydraulic pulping machine realizes the high-speed crushing of organic matter through the pulping rotor arranged inside, and cooperates with the sieve plate to realize the sorting activity of inorganic matter and organic matter, and achieves the functions of crushing, pulping and sorting in one, effectively shortening the process flow.

[0026] 5. This application is provided with an oscillation assembly. That is, when the second bevel gear provided on the right rotates, the rotation of the butt joint rod can be realized. In this way, the convex plate butt-jointed to one side of the rod can rotate to realize the up-and-down push-pull movement of the inner butt-jointed connecting rod. Therefore, the butt joint head butt-jointed to the lower end of the connecting rod can intermittently impact the sleeve through the pressure rod fixed at the bottom, so that the sleeve squeezes the filter plate provided at the lower end. The filter plate can, through the cooperation of the vertical rod, the connecting cylinder and the vibration spring, realize the reciprocating vibration effect of the filter plate with the reciprocating impact effect of the pressure rod.

The output end of the servo motor 272 is connected to a driving wheel 273. A transmission belt 274 is externally connected to the driving wheel 273. A driven wheel 275 is butted on one side of the transmission belt 274. A first bevel gear 276 is connected to the inside of the driven wheel 275. A fixed pipe 277 is vertically inserted in the middle of the first bevel gear 276, and the upper end of the fixed pipe 277 is fixedly connected to the bracket 271. Second bevel gears 278 are installed on both sides of the lower end of the fixed pipe 277. One end of both second bevel gears 278 meshes with the first bevel gear 276, and the other end of both second bevel gears 278 meshes with a third bevel gear 279. The third bevel gear 279 is connected to the bottom of the fixed pipe 277, and stirring rods 2710 are fixedly provided on both outer ends of the third bevel gear 279. An oscillation structure 2711 is butted on the side of one second bevel gear 278. A sleeve 2712 is sleeved outside the lower end of the oscillation structure 2711. The lower end of the sleeve 2712 is connected to a filter plate 2713. Vertical rods 2714 are fixedly provided on both sides of the bottom of the filter plate 2713. The lower ends of the vertical rods 2714 are inserted into a connecting cylinder 2715. A vibration spring 2716 is installed inside the connecting cylinder 2715, and the upper end of the vibration spring 2716 is connected to the lower end of the vertical rod 2714.

[0046] Specifically, the first bevel gear 276 drives the rotation of the stirring rod 2710 through the meshing transmission between the second bevel gear 278 and the third bevel gear 279, so as to realize the stirring of the slurry discharged inside the slag discharge port 26 and avoid the problem of material discharge blockage. At the same time, when the second bevel gear 278 rotates on one side, the oscillation structure 2711 is rigidly connected to the filter plate 2713 through the sleeve 2712, and combined with the elastic buffer of the vibration spring 2716, it can periodically trigger the up and down vibration of the filter plate 2713 and accelerate the solid-liquid separation efficiency inside the slurry.

[0047] Among them, the oscillation structure 2711 includes a connecting rod 27111. Convex plates 27112 are rotatably butted on both sides of the connecting rod 27111. A rotating rod 27113 is butted inside the convex plates 27112 on both sides. One end of one rotating rod 27113 is connected to the second bevel gear 278 on one side. The lower end of the connecting rod 27111 is rotatably connected to the docking head 27114. A pressing rod 27115 is fixedly connected to the bottom of the docking head 27114. The docking head 27114 slides into the sleeve 2712.

[0048] The implementation principle of the embodiment of this application is as follows: Pour the kitchen waste into the pulping cylinder 11 through the feed port 14. When the kitchen waste is inside the pulping cylinder 11, the high-speed rotation of the pulping rotor 17 can be realized. Under the tearing of the impeller blades of the pulping rotor 17 and the mutual turbulence of the slurry layers at different speeds, a huge frictional force is generated, which can strongly decompose the organic matter in the kitchen waste in the wet state. At the same time, in cooperation with the guide plates 15 equidistantly arranged on the inner wall of the pulping cylinder 11, the slurry will form a turbulent circulation to strengthen the crushing quality of the organic matter. In this way, the organic matter and inorganic impurities will be sorted through the sieve plate 16. The separated liquid is pre-collected into the liquid drainage buffer tank 6 through the liquid outlet 110. The screened inorganic impurities can enter the first transmission cylinder 21 along the slag discharge port 111 by opening the slag discharge valve 112 installed outside the slag discharge port 111; When the inorganic impurities enter the first transmission cylinder 21, the first motor 22 can drive the first shaftless spiral 23 to rotate to realize the transmission of the inorganic impurities and the further separation of the slag water inside. The separated slag water can enter the liquid drainage buffer tank 6 through the drain pipe 25 provided on the lower right side of the receiving bin 24. The slag material that falls into the receiving bin 24 can enter the slag discharge spiral conveyor 3 through the slag discharge port 26. In cooperation with the second transmission cylinder 31, the second motor 32 and the second shaftless spiral 33 provided inside the slag discharge spiral conveyor 3, the slag material can be transmitted into the screw extruder 4; Under the spiral rotation of the third shaftless spiral body 43 inside the screw extruder 4, the inorganic impurities will be transported and squeezed for dehydration. The dehydrated impurities enter the impurity temporary storage box 5 through the feed hopper 44. The impurities entering the inside of the impurity temporary storage box 5 can enter the fourth transfer cylinder 55 connected to the two lower ends of the impurity temporary storage box 5 through the spiral transmission of the fourth shaftless spiral body 54. Under the spiral transmission of the fifth shaftless spiral body 57 correspondingly arranged inside the two-sided fourth transfer cylinder 55, the impurities can be lifted and fall into the slag box of the slag transport vehicle for further external transportation and disposal; When the inorganic impurities enter the inside of the receiving bin 24, to avoid the problem of material discharge blockage when the slag material enters the second transfer cylinder 31 through the slag discharge port 26 for transmission activities. At this time, the servo motor 272 provided at the upper end of the left side of the operation support 271 can be operated to make the servo motor 272 rotate the driving wheel 273 connected to the bottom. In this way, the driving wheel 273 can cooperate with the externally connected transmission belt 274 to synchronously drive the driven wheel 275. Thus, the first bevel gear 276 connected to the inside of the driven wheel 275 can rotate simultaneously and then mesh and drive the second bevel gears 278 connected to both sides of the bottom. The two second bevel gears 278 rotating simultaneously can achieve stable self-rotation through the docking effect of the fixed pipe 277. The third bevel gear 279 meshing with the lower ends of the two second bevel gears 278 can rotate in the opposite direction synchronously with the first bevel gear 276. Driven by the rotation of the third bevel gear 279, the stirring rods 2710 arranged on the left and right sides of the outer end of the third bevel gear 279 will rotate rapidly to stir the slag material inside the slag discharge port 26, accelerating the discharge efficiency of the slag material and avoiding the problem of accumulation and blockage between the slag materials; Secondly, when the second bevel gear 278 on the right rotates, the rotation of the connecting rod 27113 docked on the right side can be realized. As the connecting rod 27113 rotates, the convex plate 27112 docked on the right side of the connecting rod 27113 will drive the connecting rod 27111 rotatably docked inside through rotational movement. The connecting rod 27111 can cooperate with the convex plate 27112 and the connecting rod 27113 docked on the other side to achieve a stable reciprocating up-and-down pushing and pulling state. Thus, the docking head 27114 docked at the lower end of the connecting rod 27111 can smoothly move up and down inside the sleeve 2712, enabling the pressing rod 27115 fixed to the lower end of the docking head 27114 to impact and extrude the sleeve 2712. The sleeve 2712 subjected to the reciprocating impact can realize the extrusion of the filter plate 2713 connected at the bottom. Since both sides of the bottom of the filter plate 2713 are slidably inserted into the connecting cylinder 2715 through the connecting vertical rods 2714 and are connected to the vibration spring 2716 provided inside the connecting cylinder 2715, through the resilience assistance of the vibration spring 2716, the filter plate 2713 can be subjected to reciprocating impact extrusion activities to achieve reciprocating vibration activities. In this way, the slag falling outside the filter plate 2713 can quickly move towards the slag discharge port 26, and further accelerate the screening of the liquid in the slag, significantly enhancing the solid-liquid separation effect.
