Description

Technical Field

[0001] This utility model belongs to the field of kitchen waste treatment technology, specifically a kitchen waste crushing and filtering device. Background Technology

[0002] With the continuous development of food waste treatment technology, various food waste crushing and filtering equipment have gradually become more widespread in practical applications, providing important support for the efficient treatment and resource utilization of food waste. However, existing equipment still has many shortcomings in structural design and functional implementation, making it difficult to fully meet the needs of efficient, intelligent, and resource-based treatment.

[0003] A search revealed that the "Intelligent Kitchen Waste Treatment Device" with publication number CN109465278B uses a counter-rotating jet disc to create a highly efficient foam mechanism, effectively removing impurities from the liquid and purifying it through subsequent filtration and adsorption. However, this device suffers from poor integration between the crushing and filtration stages; the crushed material may not promptly enter the filtration phase, easily causing blockages or reduced efficiency. Furthermore, its complex multi-stage processing results in a large equipment size, high installation and maintenance costs, and high energy consumption, making it unsuitable for small- to medium-scale applications.

[0004] Another patent, CN118417021B, entitled "Kitchen Waste Crushing and Processing Device," uses a first and second channel design to allow smaller kitchen waste to fall directly below the crushing mechanism, thereby reducing the workload and contamination of the crushing mechanism. However, the design of the solid-liquid separation and filtration stages of this device is relatively simple, making it unable to effectively handle kitchen waste with high humidity or high viscosity, and prone to filter clogging or incomplete separation. Furthermore, the lack of coordination between its crushing and filtration components may result in some material entering subsequent processing stages without being fully crushed, affecting the overall processing efficiency.

[0005] The aforementioned problems indicate that existing food waste crushing and filtration equipment still has significant shortcomings in terms of the synergy between crushing and filtration, the efficiency of solid-liquid separation, and the overall compactness and energy consumption control of the equipment. Therefore, there is an urgent need for a new type of food waste crushing and filtration equipment to optimize the connection between crushing and filtration, improve solid-liquid separation efficiency, and simultaneously reduce equipment size and energy consumption, thereby better meeting the needs of efficient, intelligent, and resource-based treatment.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0045] Example 1:

[0046] like Figures 1 to 6 As shown, this embodiment provides a kitchen waste crushing and filtering device, including: a support assembly 1, including a sleeve 103, fixedly mounted on a bracket 102, with a spiral extrusion screen 6 disposed inside; a housing 101 fixedly mounted on the sleeve 103, with a material channel 2, a crushing assembly 3, an arc-shaped vibrating screen 4, and a scraper assembly 5 disposed inside; a drive motor 7, mounted on the bracket 102, for driving the inner cutter disc 302, the convex turntable 403, and the spiral groove 601; and a large particle outlet 8, located on one side of the housing 101 and mounted on the sleeve 103.

[0047] In this embodiment, the crushing component, the arc-shaped vibrating screen screw, and the rotary extrusion screen constitute the kitchen waste crushing and filtering device involved in this application, realizing the crushing and filtering of kitchen waste.

[0048] In this embodiment, both the housing 101 and the sleeve 103 are made of aluminum alloy, which is lightweight and corrosion-resistant. The spiral groove 601 is made of high-strength alloy steel, which has strong wear and corrosion resistance.

[0049] Specifically, the material channel 2 includes: a material channel 2, which is set inside the housing 101 and is used to guide the kitchen waste so that the kitchen waste falls into the crushing component 3.

[0050] In this embodiment, the material channel 2 is made of aluminum alloy, which has strong corrosion resistance.

[0051] Specifically, the crushing component 3 includes: an outer cutter disc 301, disposed below the material channel 2; an inner cutter disc 302, rotatably disposed within the housing 101 and below the outer cutter disc 301, used to cooperate with the outer cutter disc 301 to crush kitchen waste; and a belt 12, one end of which is disposed at the shaft input end of the spiral groove 601, and the other end of which is disposed at the input end of the inner cutter disc 302, used to drive the inner cutter disc 302 to rotate.

[0052] The crushing assembly 3 consists of an outer cutter disc 301, an inner cutter disc 302, and a belt 12. Kitchen waste falls from the material channel 2. The outer cutter disc 301 blocks and initially positions the waste, placing it within the action zone of the inner cutter disc 302, where the two work together to crush it. One end of the belt 12 is connected to the input end of the spiral groove 601's shaft, and the other end is connected to the input end of the inner cutter disc 302, transmitting the rotational power of the spiral groove 601's shaft to the inner cutter disc 302, driving its rotation. During rotation, the cutting edges of the inner and outer cutters work together to cut and tear the kitchen waste into small pieces, providing suitable particle size material for subsequent screening and other processing, ensuring the stable operation of the crushing assembly 3.

[0053] Example 2:

[0054] Based on Example 1, in order to further improve the crushing efficiency, an arc-shaped vibrating screen and a spiral extrusion screen are arranged under the crushing component 3;

[0055] Specifically, the arc-shaped vibrating screen assembly 4 includes: an arc-shaped screen 401, disposed below the inner cutter disc 302, with one end connected to the large particle outlet 8, used to screen the crushed kitchen waste and vibrate the unfiltered kitchen waste into the large particle outlet 8; five sets of springs 402, one end fixedly connected to a cylinder below one end of the arc-shaped screen 401, and the other end fixedly connected to a cylinder at the upper inlet of the sleeve 103, used to rebound the arc-shaped screen 401; and a support plate 405, disposed below the arc-shaped screen 401, used to push the arc-shaped screen 401 to vibrate up and down. The top frame 404 is located under the support plate 405 and is used to push the support plate 405 to move up and down. Two sets of convex turntables 403 are provided and are rotatably set under the top frame 404 via a rotating rod, and are used to drive the top frame 404 to move up and down. Two sets of rotating shafts 406 are provided and are fixed to one end of the convex turntables 403 and rotatably set inside the housing 101, and are used to drive the convex turntables 403 to rotate. One belt 11 is located at the output end of the drive motor 7 and at the input end of the rotating shaft 406, and is used to drive the rotating shaft 1 to rotate.

[0056] Drive motor 7 drives shaft 406 to rotate via belt 11, which in turn drives convex turntable 403. The convex turntable 403 converts the rotational motion into vertical displacement of top frame 404. Top frame 404 drives support plate 405, which in turn pushes arc screen 401 to vibrate up and down. During this process, spring 402 assists; when support plate 405 pushes upward, it compresses and stores energy, and when it moves downward, it releases energy to help arc screen 401 rebound, improving screening efficiency and quality.

[0057] The crushed kitchen waste falls onto the arc screen 401. Material that meets the screen aperture size passes through the screen, while large unfiltered particles are shaken into the large particle outlet 8, achieving particle size separation and providing suitable material for subsequent processing. All components work together to complete the screening work.

[0058] As a preferred implementation method, it can screen large pieces of kitchen waste and perform secondary crushing to improve crushing efficiency.

[0059] The drive motor 7 drives the rotating shaft 406, causing the fixed convex turntable 403 to rotate. The convex turntable 403 protrudes and pushes the top frame 404 to move up and down, which in turn drives the support plate 405, which in turn pushes the arc screen 401 to vibrate up and down. The crushed kitchen waste falls onto the arc screen 401, and materials of suitable particle size pass through the screen to achieve separation. The five sets of springs 402 at one end of the arc screen 401 and at the sleeve 103 compress and store energy when the support plate 405 pushes the arc screen 401 upward, and release energy to help it rebound when it moves downward, thereby enhancing vibration, improving screening efficiency and quality, and ensuring that the arc vibrating screen assembly 4 can stably complete the screening work.

[0060] Specifically, the spiral extrusion screen 6 includes: a cylindrical screen 602, which is installed inside the sleeve 103 for filtering sewage; a spiral groove 601, which is rotatably installed inside the sleeve 103 and inside the cylindrical screen 602 for extruding kitchen waste and conveying it to the discharge port 604; a drainage pipe 603, which is connected to the sleeve 103 for discharging the extruded sewage; and a discharge port 604 for discharging the crushed and filtered kitchen waste; and a belt 10, one end of which is installed at the output end of the drive motor 7 and the other end of which is installed at the input end of the rotating shaft of the spiral groove 601 for driving the spiral groove 601 to rotate and adjusting the belt 12 to rotate.

[0061] As a preferred implementation method, it is possible to squeeze and crush the screened kitchen waste, squeeze out the sewage, and discharge the squeezed kitchen waste.

[0062] The drive motor 7 drives the spiral trough 601 to rotate within the sleeve 103 and the cylindrical screen 602 via belt 10. Kitchen waste is pushed towards the discharge port 604 by the spiral blades. Due to the reduced space and the interaction with the cylindrical screen 602, it is compressed, and the water is filtered out as wastewater, which is discharged through the drain pipe 603, achieving solid-liquid separation. The dehydrated waste is discharged from the discharge port 604. Simultaneously, the spiral trough 601 drives the inner cutter disc 302 via belt 12, reusing power, and all components work together to ensure the operation of the equipment.

[0063] Example 3:

[0064] Based on Example 2, in order to ensure the long-term operation of the device, a scraper assembly and a micro high-pressure nozzle are arranged on one side of the arc-shaped vibrating screen assembly 4.

[0065] Specifically, the scraper assembly 5 includes: a flexible scraper 503, which is disposed on the arc screen 401 and is used to remove residual waste from the arc screen 401 after operation; a scraper shaft 502, which is fixedly disposed on the flexible scraper 503 by a support rod and is rotatably disposed inside the housing 101, and is used to drive the flexible scraper 503 to swing; and a handle 501, which is fixedly disposed at one end of the scraper shaft 502 by a turntable and is disposed outside the housing 101, and is used to drive the scraper shaft 502 to rotate.

[0066] The operator manually rotates the plastic handle 501 outside the housing 101, which drives the metal scraper shaft 502 inside the housing to rotate via a turntable. The scraper shaft 502 drives the flexible rubber scraper 503 on the screen surface to swing via a support rod, adhering to the screen surface of the arc-shaped screen 401 to remove residual waste after screening, ensuring the screen is transparent and subsequent screening is efficient.

[0067] Specifically, the support component 1 also includes: a miniature high-pressure nozzle 9, of which five sets are provided, connected to the housing 101, spraying water to clean the arc screen 401.

[0068] When cleaning the arc-shaped screen 401 is required, water enters the nozzle through a water supply system connected to the miniature high-pressure nozzle 9. The miniature high-pressure nozzle 9 is existing technology, and its specific internal structure is not described here as no improvement has been made. The high-pressure water flow impacts the screen surface of the arc-shaped screen 401, washing away residual kitchen waste adhering to the screen mesh. In conjunction with the scraper assembly 5, this further ensures the cleanliness of the arc-shaped screen 401. This helps maintain the screen's permeability and prevents clogging of the screen holes.

[0069] The miniature high-pressure nozzle 9 is equipped with 5 sets, all made of brass. Brass has good corrosion resistance and can adapt to the humid environment and acid / alkali environment that may exist inside the equipment, ensuring long-term stable operation.

[0070] When in use, if it is necessary to crush and filter kitchen waste, the user starts the drive motor 7. The output of the drive motor 7 drives the inner cutter disc 302, the convex turntable 403, and the spiral groove 601 to rotate through the leather. At this time, the kitchen waste is introduced into the material channel 2 and passes through the material channel 2 to the crushing component 3 for crushing. After being crushed by the crushing component 3, it flows into the arc vibrating screen 4 for preliminary screening. Kitchen waste of appropriate size falls into the spiral extrusion screen 6 through the holes on the arc screen 401. Under the action of the spiral groove 601 and the cylindrical screen 602, the crushed kitchen waste is squeezed. The squeezed wastewater flows through the holes of the cylindrical screen 602 into the drain pipe 603 and is discharged from the drain pipe 603. The squeezed kitchen waste is sent to the discharge port 604 for discharge under the drive of the spiral groove 601.

[0071] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
