Description

Technical Field

[0001] This application relates to the technical field of waste treatment, and in particular to the treatment of food waste. Background Technology

[0002] Food waste, a major component of urban household waste, is complex, containing a mixture of various elements such as grease, protein, starch, bones, and shells. Currently, the mainstream treatment method for food waste is centralized collection and disposal, such as through fermentation to produce biogas. However, this approach essentially represents a low-value transformation of a mixture, completely ignoring the high-value potential of its different components. For example, the organic components in food waste, such as grease, starch, and some proteins, can be used as nutritionally balanced feed ingredients after appropriate processing; or the hard components, such as bones and shells, are rich in minerals and are ideal raw materials for preparing soil conditioners—their value is also severely underestimated. It is precisely because this approach treats food waste as a single mixture that it ignores the high-value potential of its different components. Utility Model Content

[0003] In view of the shortcomings of existing technologies, one of the purposes of this utility model is to provide an intelligent waste sorting, recycling and processing system.

[0004] The intelligent waste sorting, recycling, and processing system provided in this application adopts the following technical solution:

[0005] The intelligent waste sorting, recycling and processing system includes a kitchen waste recycling and processing system. The kitchen waste recycling and processing system has a feeding channel for the disposal of kitchen waste. The feeding channel is connected to a mixing system. The mixing system has a water supply port and a mixed material discharge port.

[0006] The discharge port of the mixed materials is connected to an emulsification system;

[0007] The emulsification system has an emulsification mechanism, and the discharge end of the emulsification mechanism is equipped with a sensor assembly for detecting the state of the material. The sensor assembly includes a temperature sensor, a humidity sensor, and a viscosity sensor.

[0008] The emulsification system has a computer interface circuit board with a USB communication interface, and all the sensor components are connected to the computer interface circuit board;

[0009] The discharge end of the emulsification mechanism is also equipped with an electric valve. The electric valve has a control mechanism and a control signal input terminal, which uses a USB port.

[0010] A screening mechanism is installed behind the electric valve, which has a milk discharge port and a residual solid discharge port;

[0011] The emulsion discharge port is connected to a granulator;

[0012] The drain outlet of the granulator is connected to the water supply outlet of the mixing system.

[0013] Existing food waste treatment methods can only achieve low-value conversion of mixtures, failing to rapidly produce high-value products within a single system. This application integrates a mixing system, emulsification system, and granulator into a single unit. This system enables the separation of high-value materials from food waste through the mixing and emulsification systems in a short process, and then produces high-value granular products through the granulator. Simultaneously, this application introduces sensor components to detect the mixture of emulsion and residual solids that has not yet been screened during the emulsification process. Combined with the judgment and control of a computer interface circuit board and electric valves, the quality of the output is optimized, ensuring that only fully emulsified emulsion enters the subsequent screening and granulation stages. This significantly improves the quality of the final granular product, further guaranteeing the transformation of food waste from low-value to high-value. Furthermore, this application connects the granulator's drain outlet to the mixing system, reusing the water discharged during granulation, conserving fresh water resources, reducing wastewater discharge, and thus lowering operating costs.

[0014] Preferably, the stirring system includes a stirring container, in which a rotating stirring shaft is vertically arranged, and stirring blades are arranged along the axial direction of the stirring shaft.

[0015] By adopting the above technical solution, the kitchen waste can be fully sheared and mixed by the mixing blades in the mixing container and come into uniform contact with water, achieving efficient soaking and crushing of kitchen waste. This effectively promotes the softening of emulsifiable materials and initially loosens the bond between emulsifiable and non-emulsifiable materials, providing sufficient pre-treated material for the subsequent emulsification mechanism to more efficiently break down adhesions, thereby improving the processing efficiency and effect of the entire system.

[0016] Preferably, the emulsification mechanism includes a grinding cylinder, which is connected to the discharge port of the mixture. The grinding cylinder has a grinding shaft inside, and grinding tools are arranged around the grinding shaft.

[0017] Traditional emulsification processes rely primarily on fluid shear force. However, for the oils and proteins in food waste, which are tightly bound by semi-solid organic matter, conventional stirring often provides insufficient shear force. This solution employs mechanical grinding, where a grinding shaft drives grinding blades to rotate at high speed, applying direct, high-intensity mechanical shearing and compression to the material. This force physically and thoroughly disrupts the adhesive structure between emulsifiable substances like oils and starches and non-emulsifiable hard components (bones, shells), forcibly peeling and breaking down the emulsifiable substances from the hard surface, thus greatly promoting emulsification. This mechanical grinding-based emulsification method provides highly homogenized intermediate products for subsequent screening and lays the foundation for high-quality granulation in the subsequent granulator.

[0018] Preferably, the grinding tools are arranged in a spiral pattern on the grinding shaft.

[0019] By adopting the above technical solution, the spiral-shaped grinding cutter can generate thrust along the axial direction of the grinding cylinder, causing the mixture to move along a set path inside the grinding cylinder, thus avoiding local accumulation of the mixture.

[0020] Preferably, the screening mechanism has a speed-increasing mechanism, which is connected to a screen in the shape of an inverted frustum. The screen is a screen with a mesh size that meets the fineness requirements of the emulsion output.

[0021] A milky substance collection container is provided below the screen, and the milky substance discharge port is provided on the milky substance collection container;

[0022] The end with the larger screen radius has an outwardly extending flange, and a residual solid collection container is arranged around the end with the larger screen radius. The residual solid collection container is located below the flange, and the residual solid discharge port is located on the residual solid collection container.

[0023] By adopting the above technical solution, the speed-increasing mechanism ensures that the screen can obtain sufficient rotational speed, thereby generating strong centrifugal force. The inverted frustum-shaped screen structure facilitates the upward movement of residual solid particles along the inclined plane under the action of centrifugal force and their being thrown out, while the emulsion is separated through the screen holes. This enables the full separation of products with different values ​​and uses in the screening process, which is a key link in realizing the transformation of low-value food waste into high-value food waste.

[0024] Preferably, the aperture of the screen is 0.5 mm to 2 mm.

[0025] By adopting the above technical solution, the aperture of the screen is clearly defined to be in the range of 0.5 mm to 2 mm. This ensures that most of the emulsion passes through smoothly to achieve a high yield, while intercepting most of the residual solid particles, thus achieving a balance between separation efficiency and separation purity.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Existing food waste treatment methods can only achieve low-value conversion of mixtures, and cannot quickly produce high-value products within the same system. This application integrates a mixing system, an emulsification system, and a granulator into a single unit. This system can separate high-value materials from food waste in a short process through the mixing and emulsification systems, and then produce high-value granular products through the granulator. Simultaneously, this application introduces sensor components to detect the mixture of emulsion and residual solids that has not yet been screened during the emulsification process. Combined with the judgment and control of a computer interface circuit board and electric valves, the quality of the output is optimized, ensuring that only fully emulsified emulsion can enter the subsequent screening and granulation stages. This significantly improves the quality of the final granular product and further guarantees the conversion of food waste from low-value to high-value. Furthermore, this application connects the granulator's drain outlet to the mixing system, reusing the water discharged during granulation, saving fresh water resources, reducing wastewater discharge, and thus lowering operating costs.

[0028] 2. This allows the food waste to be fully sheared and mixed by the mixing blades in the mixing container and to come into uniform contact with water, achieving efficient soaking and crushing of the food waste. It can effectively promote the softening of emulsifiable materials and initially loosen the combination of emulsifiable and non-emulsifiable materials, providing sufficient pre-treated materials for the subsequent emulsification mechanism to more efficiently break down the adhesion, thereby improving the processing efficiency and effect of the entire system.

[0029] 3. Traditional emulsification processes primarily rely on fluid shear force. However, for the oils and proteins in food waste, which are tightly bound by semi-solid organic matter, the shear force provided by conventional stirring is often insufficient. This solution employs mechanical grinding, where a grinding shaft drives grinding blades to rotate at high speed, applying direct, high-intensity mechanical shearing and compression to the material. This force physically and thoroughly disrupts the adhesive structure between emulsifiable substances such as oils and starches and non-emulsifiable hard components (bones, shells), forcibly peeling and breaking down the emulsifiable substances from the hard surface, thus greatly promoting emulsification. This mechanical grinding-based emulsification method provides highly homogenized intermediate products for subsequent screening and lays the foundation for high-quality granulation in the subsequent granulator.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1 This application will be described in further detail.

[0033] This application discloses an intelligent waste sorting, recycling, and processing system.

[0034] Reference Figure 1 The intelligent waste sorting and recycling system includes a food waste recycling system. The food waste recycling system has a feeding channel 1 for food waste input, which is connected to a mixing system 2. The mixing system 2 includes a mixing container 21, to which the feeding channel 1 connects. The mixing container 21 has a water inlet 3 for injecting water into the food waste and a mixture outlet 4 for discharging the mixed materials. A rotating mixing shaft 22 is vertically installed inside the mixing container 21, with multiple mixing blades 23 arranged axially on the mixing shaft 22. During operation, food waste is fed into the mixing container 21 through the feeding channel 1, and a certain amount of water is injected through the water inlet 3. The mixing shaft 22 drives the mixing blades 23 to rotate, crushing and mixing the food waste. This process softens the emulsifiable substances (such as oils, starches, and proteins) in the food waste and, under the action of the stirring blades 23, separates them from the hard components (bones and shells), ultimately forming a solid-liquid slurry mixture, which is then discharged from the mixture discharge port 4 at the bottom of the stirring container 21.

[0035] The mixture discharge port 4 is connected to an emulsification system, which has an emulsification mechanism 5. The emulsification mechanism 5 includes a grinding cylinder 51, which is connected to the mixture discharge port 4. The mixture discharged through the mixture discharge port 4 is discharged into the grinding cylinder 51. A rotating grinding shaft 52 is provided inside the grinding cylinder 51, and grinding blades 53 are arranged around the grinding shaft 52. In this embodiment, the grinding blades 53 are arranged in a spiral shape on the grinding shaft 52. When the grinding shaft 52 rotates at high speed, the grinding blades 53 apply shearing and extrusion to the flowing mixture, forcibly peeling off the emulsifiable substances still adhering to the surface of hard components such as bones and shells, and simultaneously breaking down these hard components to a certain extent. The product after processing by the emulsification mechanism 5 is a mixture of emulsion and hard particles.

[0036] Furthermore, to ensure that only materials reaching the predetermined emulsification level can proceed to subsequent sorting processes, this application incorporates an intelligent quality detection and control unit at the discharge end of the emulsification mechanism 5. Specifically, a discharge pipe is connected to the discharge end of the grinding cylinder 51, and a sensor assembly 6 for detecting the material state is installed on this discharge pipe. The sensor assembly 6 includes a temperature sensor, a humidity sensor, and a viscosity sensor. The emulsification system also has a computer interface circuit board with a USB communication interface, and the signal output terminals of the sensor assembly 6 are all connected to this computer interface circuit board. An electric valve 7 is also installed at the discharge end of the emulsification mechanism 5. The electric valve 7 has a control mechanism with a control signal input terminal, which uses a USB port. This control signal input terminal is also connected to the computer interface circuit board.

[0037] In this application, the computer interface circuit board has a preset set of parameter thresholds corresponding to the material's compliance status. When the real-time data detected by the sensor component 6 reaches or exceeds the preset threshold, it indicates that the material has been sufficiently emulsified. At this time, the computer interface circuit board will issue a control command to drive the electric valve 7 to open. If the detected data does not meet the standard, the electric valve 7 will be controlled to close.

[0038] A screening mechanism 8 is located behind the electric valve 7. The screening mechanism 8 has a speed-increasing and variable speed mechanism 81. In this embodiment, the speed-increasing and variable speed mechanism 81 consists of a drive motor and a speed-increasing gearbox. The speed-increasing and variable speed mechanism 81 is connected to a screen 82 in the shape of an inverted frustum. The screen 82 rotates at a high speed of several hundred revolutions per minute under the drive of the speed-increasing and variable speed mechanism 81. The screen 82 has a mesh size that meets the fineness requirements of the emulsion output. Specifically, the mesh diameter of the screen 82 is 0.5 mm to 2 mm. In this embodiment, the mesh diameter of the screen 82 is selected as 2 mm. This mesh diameter is sufficient to allow the emulsion to pass through smoothly, while effectively trapping most of the hard particles.

[0039] The screening mechanism 8 also has an emulsion collection container 12 disposed below the screen 82, and an emulsion discharge port 9 disposed on the emulsion collection container 12. The top of the inverted frustum screen 82, that is, the end of the screen 82 with the larger radius, is provided with an outwardly extending flange 13, and a residual solid collection container 14 is disposed around the end of the screen 82 with the larger radius. The residual solid collection container 14 is located below the flange 13, and the residual solid discharge port 10 is disposed on the residual solid collection container 14.

[0040] During the screening process, the mixture of emulsion and hard particles flows through the electric valve 7 into the high-speed rotating screen 82. The hard particles (such as bone fragments and shell fragments) are quickly thrown against the inner wall of the screen 82 and move upward along the inclined screen surface, eventually being ejected from the edge of the large-diameter end of the top of the screen 82 and falling into the peripheral residual solids collection container 14. They are then discharged through the residual solids discharge port 10 and used as a soil conditioner. At the same time, the emulsion passes through the mesh of the screen 82, falls into the emulsion collection container 12, and flows out from the emulsion discharge port 9.

[0041] The emulsion discharge port 9 is connected to a granulator 11. The emulsion flowing out is processed into high-density granules through extrusion, dehydration, and molding. The process wastewater generated during granulation is returned to the water supply port 3 of the mixing system 2 through a recycled water pipe as supplementary water for mixing and soaking, thus realizing the closed-loop utilization of water resources.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
