Description

Technical Field

[0001] This utility model relates to the field of kitchen waste treatment technology, and in particular to a highly efficient and environmentally friendly device for extracting and separating grease from kitchen waste. Background Technology

[0002] The environmentally friendly kitchen waste grease extraction and separation device is a professional equipment that efficiently separates grease, solid residue and water from kitchen waste, thereby realizing the resource utilization of kitchen waste, reducing environmental pollution and promoting the development of a circular economy.

[0003] Currently, while existing environmentally friendly kitchen waste oil extraction and separation devices can crush ordinary kitchen waste, they cannot effectively handle situations where solid hard kitchen waste such as bones cannot enter between the two sets of crushing blades, resulting in insufficient crushing. This leads to poor overall crushing effect, uneven material particle size, and affects the quality of subsequent oil extraction and separation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to effectively handle solid hard kitchen waste like bones between the two sets of pulverizing blades, resulting in insufficient pulverization and poor overall pulverization effect. Therefore, this invention proposes a highly efficient and environmentally friendly kitchen waste grease extraction and separation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A highly efficient and environmentally friendly device for extracting and separating grease from kitchen waste includes: A three-phase centrifuge has a feed inlet on one side of its top. A frame is fixedly installed on the top of the feed inlet, and a cover is fixedly installed on the top of the frame. The frame is equipped with a crushing mechanism for crushing food waste. The cover is equipped with a pressing mechanism to assist in crushing food waste. The crushing mechanism is equipped with a linkage mechanism to drive the pressing mechanism to work when the crushing mechanism is working.

[0006] In one possible design, the crushing mechanism includes two rotating rollers symmetrically arranged and rotatably disposed inside the frame. Both rollers have a plurality of uniformly distributed crushing blades fixedly disposed on the outer side of the inner side of the frame. The plurality of crushing blades on the two rollers are staggered. Both rollers have gears fixedly disposed at the outer ends of the frame. The two gears mesh and drive each other. A motor is fixedly disposed on one side of the frame. The output shaft of the motor is fixedly connected to one of the rollers.

[0007] In one possible design, the pressing mechanism includes two symmetrically arranged grooves on both sides of the cover frame, with the same support rod slidably arranged inside the two grooves, and a pressing frame fixedly arranged on the outside of the support rod on the inner side of the cover frame.

[0008] In one possible design, the linkage mechanism includes a turntable fixedly mounted on one end of another roller located next to the motor. An eccentric shaft is fixedly mounted on one side of the turntable off-center. A linkage rod is hinged to the outside of the eccentric shaft, and the other end of the linkage rod is hinged to one end of a support rod.

[0009] In one possible design, a guide frame is fixedly installed on one side of the cover, and the top wall of the guide frame is inclined.

[0010] In one possible design, the pressure frame is fan-shaped, narrow at the top and wide at the bottom, and the bottom of the pressure frame is arc-shaped.

[0011] In this application, when starting to use the device, first connect the entire device to the power supply, pour the collected kitchen waste into the guide rack. The top wall of the guide rack is inclined to facilitate the smooth sliding of the material into the cover. The kitchen waste entering the cover will fall into the crushing area inside the frame. At this time, start the motor fixed on one side of the frame. The motor starts to run, and its output shaft drives one of the rollers to rotate. Since gears are fixedly installed on both rollers extending to the outer end of the frame, and these two gears mesh and drive each other, when one roller rotates, the other roller will rotate in the opposite direction synchronously. During the process of the two rollers rotating in the opposite direction, the intersecting crushing blades will crush the kitchen waste entering the frame. While the crushing mechanism is working, the turntable rotates along with the roller, and the eccentric shaft fixed off-center on one side of the turntable also rotates. As the eccentric shaft rotates, the linkage rod pulls the support rod to slide up and down in two symmetrically opened grooves on both sides of the cover. When the support rod slides down, it drives the pressing frame to move down, applying pressure to the kitchen waste in the frame. For some solid hard waste, such as bones, it is not easy to enter them when crushed by the two sets of crushing blades. However, the downward pressure of the pressing frame can force these kitchen wastes into the two sets of crushing blades for thorough crushing, which plays an auxiliary role in crushing kitchen waste. After being thoroughly crushed, the kitchen waste is discharged from the bottom of the frame, and the sliding material finally enters the three-phase centrifuge. At this point, the three-phase centrifuge starts working. When the material enters the high-speed rotating drum, due to the difference in specific gravity, the solid particles, the heavy liquid phase (such as water), and the light liquid phase (such as oil) are subjected to different centrifugal forces. According to the magnitude of the centrifugal force, a concentric solid layer and two liquid layers are formed from the outside to the inside. The screw conveyor pushes the solid particles that have settled on the drum wall toward the slag outlet, realizing the continuous discharge of solids. The liquids are discharged from their respective liquid guide ports. The centrifugal pump component can adjust the position of the neutral layer of the heavy and light phases and control the discharge layer, thereby realizing the separation of solid, liquid, and liquid phases and completing the extraction and separation of grease from kitchen waste.

[0012] This utility model has the following beneficial effects: In this invention, the crushing mechanism is designed so that two meshing gears driven by a motor rotate the rollers in opposite directions, creating a highly efficient shearing force field with staggered crushing blades, which can quickly crush soft organic matter in kitchen waste.

[0013] In this invention, the pressing mechanism allows solid, hard waste such as bones to be pressed between two sets of crushing blades when the pressing frame is pressed down. This solves the problem that such waste is difficult to enter the blades and is not crushed sufficiently in conventional crushing processes. It achieves more comprehensive and thorough crushing of kitchen waste, providing more uniformly sized material for the subsequent three-phase separation process, and effectively improving the overall quality of oil extraction and separation from kitchen waste.

[0014] In this invention, the linkage mechanism is used to drive the linkage rod to move the support rod back and forth in the groove by rotating the eccentric shaft with the rotating roller. This allows the pressing frame and the crushing mechanism to move synchronously. This not only simplifies the device structure and reduces energy consumption, but also ensures that the pressing frame presses down during the crushing process, assisting the crushing blades in fully processing hard waste. This significantly improves the crushing efficiency and uniformity of kitchen waste, laying the foundation for efficient grease separation in the future. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] In one embodiment Reference Figure 1-4 An extraction and separation device, comprising: The three-phase centrifuge 1 (model: LW450) is mainly composed of a drive unit, differential, screw conveyor, drum, machine cover, machine base, control system, centrifugal pump, bearings, etc. Its working principle is based on the centrifugal sedimentation principle. When the material enters the high-speed rotating drum, due to the different specific gravities of solid particles, heavy liquid phase such as water and light liquid phase such as oil, the centrifugal force is also different. According to the magnitude of the centrifugal force, a concentric solid layer and two liquid layers will be formed from the outside to the inside. The screw conveyor pushes the solid particles that have settled on the drum wall to the slag outlet to realize the continuous discharge of solids, while the liquid is discharged from its respective liquid guide port. The centrifugal pump component can adjust the position of the neutral layer of heavy and light phases and control the discharge layer, thereby realizing the separation of solid, liquid and liquid three phases. It is the core component of the whole device to realize the extraction and separation of oil. A feed port 2 is opened on one side of the top of the three-phase centrifuge 1 to receive the pre-treated kitchen waste material.

[0019] A frame 3 is fixedly installed at the top of the feed inlet 2. The frame 3 provides support and space for the entire crushing process. A crushing mechanism is installed on the frame 3 for crushing food waste. The crushing mechanism includes two rotating rollers 5 symmetrically arranged inside the frame 3. Multiple uniformly distributed crushing blades 6 are fixedly installed on the outer side of the two rotating rollers 5 inside the frame 3. The multiple crushing blades 6 on the two rotating rollers 5 are staggered, so that the crushing blades can more fully shear and crush the food waste when the rollers rotate. Gears 7 are fixedly installed at the outer ends of the two rotating rollers 5 extending to the frame 3. The two gears 7 mesh and drive each other. A motor 8 is fixedly installed on one side of the frame 3. The output shaft of the motor 8 is fixedly connected to one of the rotating rollers 5. When the motor 8 starts, its output shaft drives the rotating roller 5 connected to it to rotate. Through the meshing transmission of the two gears 7, the other rotating roller 5 will rotate synchronously in the opposite direction, thereby realizing the crushing action of the crushing blades 6 on the two rotating rollers 5 on the food waste.

[0020] A cover 4 is fixedly installed on the top of the frame 3. The cover 4 provides support and storage space for the entire pressing process. A pressing mechanism is installed on the cover 4 to assist in the crushing of kitchen waste. The pressing mechanism includes two slid grooves 9 symmetrically opened on both sides of the cover 4. The same support rod 10 is slidably installed inside the two slid grooves 9. A pressing frame 11 is fixedly installed on the outside of the support rod 10 inside the cover 4. Since some kitchen waste is solid, such as hard waste like bones, it is not easy to enter the two sets of crushing blades 6 when crushing. The pressing frame 11 is a fan shape that is narrow at the top and wide at the bottom, and the bottom is arc-shaped to adapt to the crushing blades 6. This ensures that the pressing frame 11 will not be damaged by the crushing blades 6 when pressing down on the kitchen waste, and at the same time, it can press the hard waste into the two sets of crushing blades 6 for thorough crushing.

[0021] The crushing mechanism is equipped with a linkage mechanism to drive the pressing mechanism when the crushing mechanism is working. The linkage mechanism includes a turntable 12 fixedly mounted on one end of another roller 5 located next to the motor 8. An eccentric shaft 13 is fixedly mounted on one side of the turntable 12 off-center. A linkage rod 14 is hinged to the outside of the eccentric shaft 13. The other end of the linkage rod 14 is hinged to one end of the support rod 10. When the motor 8 drives the roller 5 to rotate, the turntable 12 rotates accordingly, and the eccentric shaft 13 performs a circular motion. Through the linkage rod 14, the support rod 10 is pulled to slide up and down in the slide groove 9, thereby driving the pressing frame 11 to move up and down, realizing the auxiliary pressing and crushing action of kitchen waste.

[0022] This application can be used in the field of efficient and environmentally friendly kitchen waste oil extraction and separation devices, and can also be used in other fields applicable to this application.

[0023] In another embodiment Reference Figure 1-2 A high-efficiency and environmentally friendly kitchen waste oil extraction and separation device is applied to the technical field of high-efficiency and environmentally friendly kitchen waste oil extraction and separation devices. A guide frame 15 is fixedly installed on one side of the cover 4. The top wall of the guide frame 15 is inclined to facilitate the smooth introduction of the collected kitchen waste into the cover 4, and then into the frame 3 for crushing.

[0024] However, as is well known to those skilled in the art, the working principles and wiring methods of the three-phase centrifuge 1 and the motor 8 are conventional methods or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0025] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
