Description

Technical Field

[0001] This utility model relates to the field of shredder technology, specifically a kitchen waste shredder. Background Technology

[0002] Food waste refers to organic waste generated in households, restaurants, canteens, and other similar locations. It mainly includes food scraps, vegetable leaves, fruit peels, bones, and cooking oil. This type of waste often contains moisture, grease, protein, and carbohydrates, making it a high-moisture, high-organic-content waste. Before processing, it needs to be pulverized. Due to its high moisture content, existing pulverizers often only use pulverizing rollers to pulverize the food waste. After the rollers pulverize the food waste, the solids and water are mixed together. Lacking an effective solid-liquid separation structure, the waste and water enter subsequent filtration or separation equipment together. This treatment method leads to low separation efficiency because the pulverized material is viscous and complexly mixed, increasing the difficulty of solid-liquid separation. Utility Model Content

[0015] 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.

[0016] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, 6, and 7, this utility model provides a technical solution: a kitchen waste shredder, comprising: a shredder box 1 with an inverted pyramidal structure, two shredder rollers 2 rotatably connected inside the shredder box 1, a drive unit installed on the outside of the shredder box 1 to drive the shredder rollers 2 to rotate simultaneously toward the center of the shredder box 1; a rotating plate 5 rotatably placed at the discharge port at the bottom of the shredder box 1; a conveying pipe 8 obliquely fixed to the bottom of the shredder box 1, a spiral conveying rod 18 rotatably installed inside the conveying pipe 8, multiple filter holes with through-hole structure opened on the outer wall of the conveying pipe 8, a squeezing part installed at one end of the conveying pipe 8, the squeezing part including a squeezing plate 17 for squeezing kitchen waste; and a drain pipe 10 placed below the conveying pipe 8, the drain pipe 10 communicating with the filter holes.

[0017] It should be noted that this embodiment is equipped with a controller and a corresponding operation panel. Garbage is poured into the pulverizing chamber 1 from the top, and the drive unit simultaneously moves the pulverizing rollers 2 towards the center. The pulverizing teeth of the two rollers 2 are interlaced and have an arc-shaped structure, thus pulverizing large objects in the garbage. The pulverized objects enter the bottom of the pulverizing chamber 1. Under the rotation of the rotating plate 5, the pulverized waste inside the pulverizing chamber 1 flows downward into the conveying pipe 8. Under the action of the filter holes, the internal liquid passes through and enters the drain pipe 10. A water pump then draws the liquid inside the drain pipe 10 into the oil separator, where it is further processed by a screw conveyor. Under the action of rod 18, the crushed material is conveyed upward at an incline along conveying pipe 8. During this period, the internal water flows downward under the action of gravity and enters the drain pipe 10 through the filter hole below. When the crushed kitchen waste comes into contact with the squeezing plate 17, the kitchen waste is squeezed at the end of conveying pipe 8 under the action of spring 16 pushing the squeezing plate 17. In this way, the water inside the crushed material is squeezed out through the accumulation and squeezing of kitchen waste. The squeezed water is discharged into the drain pipe 10 through the filter hole located above. When the pressure of the crushed kitchen waste is greater than that of spring 16, the kitchen waste pushes the squeezing plate 17 open, causing the kitchen waste to fall into the fermentation equipment below.

[0018] In one embodiment, the drive unit includes gears fixed to the ends of the two crushing rollers 2, the two gears meshing together, and a drive motor 4 fixed to one side of the crushing box 1, the output end of the drive motor 4 being fixedly connected to one of the gears.

[0019] It should be noted that in this embodiment, the drive motor 4 is controlled by the operation panel. The drive motor 4 drives one gear to rotate, and the two gears simultaneously drive the crushing roller 2 to rotate. The crushing roller 2 then crushes the waste that falls into the crushing box 1.

[0020] In one embodiment, a rotating shaft is rotatably connected to the bottom of the crushing box 1, and a rotating plate 5 is fixed at an equal angle to the outside of the rotating shaft. A drive motor 6 for driving the rotating shaft is fixed to one side of the crushing box 1.

[0021] It should be noted that in this embodiment, the drive motor 2 6 is operated by a switch. The drive motor 2 6 drives the rotating plate 5 to rotate at the discharge port of the crushing box 1, thereby pushing the crushed kitchen waste downward to prevent it from accumulating and clogging the discharge port.

[0022] In one embodiment, a drive motor 7 is fixedly connected to one end of the conveying pipe 8. The drive motor 7 is fixedly connected to the output end of the spiral conveying rod 18. The filter holes include filter hole 19 and filter hole 12. Filter hole 19 is equidistantly arranged at the position of the conveying pipe 8 below the crushing box 1. A connecting box 9 is fixedly connected between the drain pipe 10 and the conveying pipe 8. Filter hole 19 is placed inside the connecting box 9. Filter hole 12 is opened on the outside of the conveying pipe 8 and located at the end opposite to filter hole 19. A collecting cylinder 11 is fixedly connected to the outside of the conveying pipe 8 at the position corresponding to filter hole 12. A connecting support 13 is fixedly connected between the bottom of the collecting cylinder 11 and the drain pipe 10 for communication and support.

[0023] It should be noted that in this embodiment, the drive motor 37 drives the spiral conveyor rod 18 to rotate inside the conveying pipe 8. Under the action of gravity inside the conveying pipe 8, the water of the crushed waste enters the connecting box 9 through the filter hole 2 19 and then enters the drain pipe 10. The spiral conveyor rod 18 rotates to convey the crushed material inside the conveying pipe 8 at an incline upward. When the kitchen waste is squeezed by the squeezing part at the end of the conveying pipe 8, its water enters the collection cylinder 11 through the filter hole 12, and then enters the drain pipe 10 through the collection cylinder 11 and the connecting support 13. This achieves solid-liquid separation while conveying, and the water can be squeezed and separated by the squeezing part.

[0024] In one embodiment, the extrusion section further includes a connecting frame 15 fixed to the end of the conveying pipe 8, one end of the spiral conveying rod 18 is rotatably connected to the connecting frame 15, one end of the spiral conveying rod 18 is movably mounted with an extrusion plate 17, the extrusion plate 17 rotates and slides at the end of the spiral conveying rod 18, and a spring 16 is sleeved on the outside of the spiral conveying rod 18 and between the extrusion plate 17 and the end of the connecting frame 15.

[0025] It should be noted that in this embodiment, the spiral conveyor rod 18 is fixedly connected to the conveying pipe 8, and one end of the spiral conveyor rod 18 is rotatably connected to the connecting frame 15. The spring 16 applies pressure to the extrusion plate 17, so that the extrusion plate 17 is pressed tightly against the discharge port of the conveying pipe 8. When the spiral conveyor rod 18 conveys the crushed kitchen waste forward and squeezes it inside the sealing of the extrusion plate 17, when the extrusion pressure is greater than the elastic force of the spring 16, the crushed kitchen waste compresses the spring 16 through the extrusion plate 17, causing the extrusion plate 17 to separate from the end of the conveying pipe 8, thereby allowing the kitchen waste to fall into the fermentation equipment.

[0026] In one embodiment, the device further includes a lifting mechanism, which includes a lifting frame 20 fixedly connected to one side of the crushing box 1. The inner side of the lifting frame 20 is provided with a straight guide rail groove 3 and an arc-shaped guide rail groove 14. A lifting plate 22 is slidably connected to the middle of the lifting frame 20. The two sides of the top of the lifting plate 22 are slidably connected to the guide rail groove 14, and the two ends of the bottom of the lifting plate 22 are slidably connected to the guide rail groove 3. A chain transmission assembly 21 for driving the lifting plate 22 to rise and fall is fixedly connected to one side of the lifting frame 20.

[0027] It should be noted that in this embodiment, the chain drive assembly 21 includes two sprockets mounted on one side of the lifting frame 20, with a chain connecting the two sprockets. A motor driving the lower sprocket is fixed to the outer side of the lifting frame 20. A metal plate is fixed to the middle of the chain, and the metal plate is rotatably connected to one bottom end of the lifting plate 22, hooking the hook plate on one side of the lifting plate 22 onto the edge of the trash can. The chain rotation drives the lifting plate 22 to move upward. During this process, the bottom of the lifting plate 22 slides vertically upward inside the first guide groove 3, and the two sides of its top slide inside the second guide groove 14. When the two ends of the top of the lifting plate 22 slide into the arc-shaped structure of the second guide groove 14, the lifting plate 22 is in a horizontal state. This allows the trash in the trash can to be emptied.
