Description

Technical Field

[0001] This invention relates to the field of kitchen waste treatment equipment technology, specifically to an integrated closed-loop organic treatment device for kitchen waste. Background Technology

[0002] Currently, food waste disposers are devices used to process kitchen waste, reducing the amount of waste sent to landfills by processing food scraps and organic waste in home or commercial environments.

[0003] In current food waste disposers, the common processing method is to crush organic waste into small particles using granulation technology, reducing its volume and facilitating subsequent processing. This method can accelerate the decomposition of waste, reduce subsequent waste processing time, and is conducive to subsequent resource utilization. The main problem faced by food waste disposers on the market is that the oil residue after crushing is difficult to meet emission standards, and there is a lack of further processing of the crushed waste.

[0004] One existing integrated treatment method for kitchen waste typically involves filtering the oil mixture, drying the filtered residue, and then sending it to a shredder. The shredder then crushes the residue to produce reusable material. However, the shredder generates significant noise and vibration, which is not conducive to long-term use.

[0005] A kitchen waste treatment system and method disclosed in the prior art (CN118305158B) involves pre-treatment using a garbage disposal unit at the bottom of the kitchen sink. The oil from the garbage disposal unit then enters an oil-water separator, and the remaining residue enters a primary and secondary filtration unit. Specifically, the oil is further separated by compression. The remaining residue is then collected after being compressed into cakes, and the separated oil continues to enter the oil-water separator. However, while this method achieves further recycling of residue, the cake-shaped waste discharged contains a certain proportion of oil due to the compression-based oil filtration method. This oily waste is prone to fermentation and odor in the garbage collection bin, affecting user experience. Furthermore, the residual oil in the cake-shaped waste is detrimental to subsequent applications in agricultural composting and incineration. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an integrated closed-loop organic treatment device for kitchen waste.

[0010] Furthermore, the water purification chamber is equipped with a first heating unit and a first pump unit. The first heating unit is used to provide hot water to the return pipeline, and the first pump unit is arranged in the return pipeline and draws purified water from the water purification chamber.

[0011] Furthermore, an activated carbon unit is provided within the air passageway; The air passage includes an exhaust section and an air inlet section. The air inlet section is located at the output port of the exhaust unit. The exhaust section is connected to the air inlet section from the bottom of the water purification chamber, and the air outlet of the exhaust section extends to the outside of the water purification chamber and is connected to the sewer. Alternatively, the exhaust section and the air inlet section are arranged alternately, with the air inlet section delivering hot air to the water purification chamber and the exhaust section guiding the gas in the water purification chamber to the sewer.

[0012] Furthermore, the receiving chamber is provided with a first overflow plate, a second overflow plate, and a third overflow plate along the oil-water flow direction; The first overflow port is defined between the top of the first overflow plate and the receiving chamber, and the oil-water inlet extends to the bottom of the first overflow port; The second overflow port is defined between the bottom of the second overflow plate and the receiving chamber, and the third overflow port is defined between the top of the third overflow plate and the receiving chamber. The second overflow port is located below the first overflow port, and the third overflow port is located above the second overflow port.

[0013] Furthermore, the water purification chamber is also equipped with a water inlet connected to an external water source, and a temperature controller is provided on the exhaust section; the bottom of the receiving chamber is equipped with a sewage outlet, and the top of the receiving chamber is equipped with an oil outlet.

[0014] Furthermore, the intermediate processing device also includes a screening barrel, the input side of which is provided with a first oil-water input pipe connected in the material distribution path of the material distribution channel, and a second oil-water input pipe connected to the bottom of the primary filter tank; the output side of the screening barrel is provided with a residue output pipe connected to the first material barrel, and an oil-water output pipe connected to the oil-water separation box.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects: The present invention achieves closed-loop processing of kitchen waste from initial sorting to final resource utilization by working in concert with the upper pretreatment device, intermediate treatment device, drying treatment device, oil-water separation box, air passage and return passage. In addition, it makes full use of heat energy and filtered water in the intermediate process to optimize the treatment effect of kitchen waste.

[0018] In the process of treating kitchen waste, users first pour the kitchen waste mixture into the primary filter tank. The screen and auxiliary material distribution unit of the primary filter tank first perform coarse sorting of the kitchen waste, effectively separating solid residue and oil-water mixture, avoiding blockage caused by large impurities directly entering the subsequent stages. At the same time, the separated oil-water mixture can enter the oil-water separation box. The separated solid residue enters the waste processor, where it is crushed to provide a basis for subsequent compression and drying. Then, the material distribution channel and the first feeding unit ensure the orderly transportation of the residue, and the residue is compressed during transportation to further separate the oil-water mixture and reduce residue. The drying device uses a combination of hot and cold air drying. Solid residue is first dried with cold air, and then further conveyed by a second feeding unit, continuously receiving cold air during the conveying process. The residue after the second cold air cycle enters the second material tank to receive hot air drying, and is finally discharged through the dry residue outlet at the bottom. Fermentation agents can be added in the high-temperature second material tank to significantly reduce the moisture content of the residue and produce uniformly dried organic fertilizer. The oil-water separation box uses a multi-stage overflow plate design to efficiently separate oil and clean water, improving the purity of oil recovery. The air passage guides the hot air from the drying process to the oil-water separation box to realize waste heat utilization and reduce energy consumption. At the same time, the clean water chamber is connected to the sewer, and the hot air from the second material tank is discharged after reuse. The return flow path returns the separated purified water to the primary filter tank or the feed inlet of the garbage disposer, realizing the recycling of water resources and reducing external water demand.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0022] like Figure 1-11 As shown, an integrated closed-loop organic waste treatment device for kitchen waste includes: The upper pretreatment device includes an open primary filter tank 1 and a garbage disposal unit 2. The primary filter tank 1 includes at least a screen 1.1 for receiving the garbage mixture and an auxiliary material distribution unit 1.2 that acts on the screen 1.1. The garbage mixture is separated into solid residue and oil-water mixture through the screen 1.1, thus completing the first-stage separation. The auxiliary material distribution unit 1.2 actuates the screen 1.1 and guides the residue to the feed inlet 2.1 of the garbage disposal unit 2. The primary filter tank 1 is configured to have at least one dumping opening for users to conveniently dispose of kitchen waste, and to allow the solid residue separated by the primary filter tank 1 to enter the discharge opening of the garbage disposal unit 2. The garbage disposal unit 2 further crushes the solid residue to achieve the second-stage separation. The intermediate processing device includes a material distribution channel 3 that receives the waste processor 2, and a first feeding unit 3.1 that is movably disposed in the material distribution channel 3. The material distribution channel 3 is equipped with a residue outlet 3.2. After receiving the residue from the waste processor 2, the material distribution channel 3 further separates the oil-water mixture in the residue to achieve three-stage separation. The drying device includes a first material tank 4 and a second material tank 5 connected at the top. The top of the first material tank 4 is connected to the residue outlet 3.2, meaning that the residue output from the material distribution channel 3 will enter the top of the first material tank 4 and descend from the top of the first material tank 4. Furthermore, the first material tank 4 is equipped with a cold air unit 4.1 and a second feeding unit 4.2 inside. The cold air unit 4.1 is used to perform preliminary drying on the residue inside, and the second feeding unit 4.2 transports the bottom residue to the top of the second material tank 5. Thus, the residue in the first material tank 4 will undergo a secondary drying process, achieving further oil-water separation. The second material tank 5 is equipped with a hot air unit 5.1 and a dry residue outlet 5.2 at the bottom. The residue from the first material tank 4 will enter the second material tank 5 from the top and be fully dried by the hot air inside. Then it will be discharged from the dry residue outlet 5.2 at the bottom, thus completing the oil-water separation and outputting dry organic residue. The oil-water separator 66 includes a receiving chamber 6.1 and a clean water chamber 6.2. The receiving chamber 6.1 is provided with an oil-water inlet 6.3 for receiving sludge and oily water from the primary filter tank 1 and the distribution channel 3. Overflow plates are arranged at intervals in the receiving chamber 6.1 along the flow direction of the sludge and oily water. The overflow plates divide the receiving chamber 6.1 into multiple overflow areas. Through the multi-stage overflow plates, the oil-water mixture is separated into layers according to its density. The clean water chamber 6.2 is connected to the water phase outlet of the overflow area. The ventilation passage 7 is sequentially connected to the first material tank 4, the second material tank 5 and the clean water chamber 6.2. An exhaust unit is arranged between the first material tank 4 and the second material tank 5. The exhaust unit delivers hot air from the second material tank 5 into the first material tank 4. The hot air in the first material tank 4 rises and enters the bottom of the clean water chamber 6.2 under the action of the exhaust unit. After the clean water chamber 6.2 absorbs the heat of the hot air, the ventilation passage 7 connects from the bottom of the clean water chamber 6.2 to the sewer, that is, the cold air is discharged into the sewer. The return flow path 8, connected to the clean water chamber 6.2, draws clean water to at least the vicinity of the screen 1.1 and / or the inlet 2.1 of the garbage disposal unit 2. By drawing clean water from the clean water chamber 6.2, the return flow path 8 returns it to the area of ​​the screen 1.1 in the primary filter tank 1 and near the inlet 2.1 of the garbage disposal unit 2. This not only achieves water resource recycling and reduces the use of external fresh water, but also utilizes the relatively clean water after oil-water separation to regularly rinse the screen 1.1 of the primary filter tank 1, preventing clogging, and keeping the inlet 2.1 of the garbage disposal unit 2 clean to avoid residue adhesion, ensuring the smooth operation of the entire processing flow. Furthermore, this circulating water system helps improve overall processing efficiency. Through continuous water flow, it accelerates the separation process of solid waste and oil-water mixtures, making the entire integrated kitchen waste sorting device more efficient and environmentally friendly.

[0023] It should be noted that the purpose of applying cold air to the first material bin 4 is to reduce the moisture content of the residue in preparation for the hot air drying in the second material bin 5. If hot air is used directly, it will waste energy. On the other hand, the organic matter in kitchen waste is easily decomposed and deteriorated at high temperatures. Drying with cold air can avoid excessive deactivation of organic matter. Moreover, if hot air is applied directly to the residue, it may cause the surface of the residue to dehydrate too quickly and form a hard shell, which will hinder the removal of internal moisture and prolong the drying time. Cold air can keep the surface pores of the residue open. With the action of cold air followed by hot air, it is ensured that the residue is dehydrated evenly from the inside out. In addition, the temperature of the cold air in the first material bin 4 also needs to be controlled. In this embodiment, the hot air from the second material bin 5 can also flow back to the first material bin 4 to use the residual heat of the second material bin 5 to control the temperature inside the first material bin 4 and reduce the total energy consumption.

[0024] like Figure 11 As shown, as a layout of an integrated kitchen waste sorting device, the device is configured on a kitchen countertop, specifically including a work surface 9 with a sink 9.1. The garbage disposal unit 2, as a general appliance, is usually located at the bottom of the sink 9.1. The pre-filter 1 is recessed in the work surface 9 and connected to the sink 9.1.

[0025] Specifically, the discharge opening of the pre-filter 1 is located at the top of the sink 9.1 and faces the sink 9.1. The pouring opening of the pre-filter 1 can be set to be completely open. Thus, the pre-filter 1 is configured with three walls: the upper part is the pouring opening, one side is the discharge outlet obstruction, and the bottom is the screen 1.1. This integrated design of the sink 9.1 and the pre-filter 1 conforms to the actual layout of the kitchen. Users can directly pour kitchen waste into the pre-filter 1, which is convenient to operate.

[0026] As a further embodiment of the primary filter tank 1, the auxiliary material distribution unit 1.2 can be selected as a vibrating screen. The screen 1.1 can be integrated on the vibrating screen. The screen 1.1 can be driven to vibrate by a vibrating motor, thereby separating the solid material residue through vibration. The solid material residue will enter the water tank 9.1 with the vibration.

[0027] In this embodiment, the primary filter tank 1 and the vibrating screen are preferably set in an inclined position. For the primary filter tank 1, the oil-water mixture separated by the vibrating screen will be guided to the bottom for easy discharge. For the vibrating screen, its inclined direction is preferably set towards the feed inlet 2.1 in the water tank 9.1 so as to fix the material residue into the waste processor 2.

[0028] As another implementation of the primary filter tank 1, in order to further optimize the transmission of solid slag and prevent it from being left on the screen 1.1, the auxiliary material distribution unit 1.2 can also be set as a stainless steel mesh conveyor belt, the conveying surface of which is the screen 1.1. That is to say, the screen 1.1 is also integrated on the conveyor belt to forcibly send the solid slag out of the primary filter tank 1.

[0029] To improve safety, a protective cover can be installed above the primary filter tank 1 to prevent users from touching it with their hands, or a resistance sensor can be installed on the conveyor belt to stop when the conveying resistance reaches a set threshold.

[0030] It is worth mentioning that the purified water from the return channel can further optimize the primary separation of kitchen waste.

[0031] Further reference Figure 9 and Figure 11 As shown, in the embodiment of the primary filter tank 1 described above, at least above the primary filter tank 1, there is an output section of the return flow path 8, specifically referring to a water outlet pipe located at the top edge of the primary filter tank 1. The water outlet pipe is preferably made of stainless steel thin pipe and is embedded between the operating table 9 and the top of the primary filter tank 1. It has multiple small holes and is connected to the return flow path 8, thereby applying flowing water to the primary filter tank 1 in real time to reduce adhesion and blockage, extend the equipment life, and reduce the frequency of manual cleaning by the user, thus improving the convenience of use.

[0032] Correspondingly, the water outlet pipe can also be configured on the top of the sink 9.1, similarly positioned between the work surface 9 and the top of the sink 9.1, thereby rinsing the inside of the sink 9.1, reducing the use of external water sources and improving water resource utilization. The water outlet pipe can be configured on the primary filter tank 1 or on the water tank 9.1. In a preferred embodiment, the water outlet pipe is configured on the top of both the primary filter tank 1 and the water tank 9.1, thereby realizing multi-point cleaning and improving the system's self-cleaning and maintenance capabilities.

[0033] Furthermore, to improve the pretreatment of the slag, the primary filter tank 1 is provided with a first water outlet pipe 8.1 that is arranged around the screen 1.1, and the upper open side of the water tank 9.1 is provided with a second water outlet pipe 8.2. The first water outlet pipe 8.1 is connected to the return flow path 8, and the second water outlet pipe 8.2 is connected to the return flow path 8, so as to control the first water outlet pipe 8.1 and the second water outlet pipe 8.2 respectively. Alternatively, the first water outlet pipe 8.1 and the second water outlet pipe 8.2 are connected, in which case the first water outlet pipe 8.1 and the second water outlet pipe discharge water simultaneously.

[0034] like Figure 4As shown, as a further embodiment of the material distribution channel 3, the first feeding unit 3.1 within the material distribution channel 3 is preferably a compression-type auger. The material distribution channel 3 can be horizontally arranged, with its upper interface connected to the discharge port 2.2 of the waste processor 2. The solid slag is conveyed forward by the compression of the auger. During the conveying process, the compression action of the auger causes the oil-water mixture in the slag to further precipitate. This precipitated oil-water mixture flows out through the pre-set holes or gaps on the material distribution channel 3 and is conveyed toward the oil-water separation box 6, achieving further separation of oil and water from the solid slag. The end of the material distribution channel 3 is provided with a residue outlet 3.2, from which the solid slag after compression separation is discharged and enters the subsequent drying treatment device.

[0035] The material distribution channel 3 can be selected to have a length of 600mm, an outer diameter of 220mm, and a wall thickness of 2mm. The outer part of the first conveying pipe unit is a stainless steel screening sleeve 3.3, which is equipped with a waste oil and water outlet hole 3.4. The diameter of the hole is preferably 50 to 60 mils. The auger is preferably a solid auger, and the outer periphery of the auger is extended with a brush, the length of which can be selected to be 3 to 4mm.

[0036] like Figures 5 to 7 As shown, in terms of layout, the residue outlet 3.2 of the material distribution channel 3 is located on the top of the first material bucket 4. The first material bucket 4 and the second material bucket 5 are vertically arranged bucket-shaped structures, with end caps installed at the upper end for material residue to enter and exit, or for airflow to enter and exit, as well as for the arrangement of hot air unit 5.1 or cold air unit 4.1.

[0037] To accommodate the internal structure of the cabinet, the height of the first material bin 4 and the second material bin 5 can be selected as 50cm. The first material bin 4 is for accommodating the vertical second feeding unit 4.2, and its inner diameter is 40cm. The inner diameter of the second material bin 5 can be selected as 30cm.

[0038] Further reference Figure 6 Specifically, the first material hopper 4 is vertically spaced with multiple layers of first conveyor belt units 4.3, and the second material hopper 5 is vertically spaced with multiple layers of second conveyor belt units 5.3. The first conveyor belt units 4.3 and the second conveyor belt units 5.3 have the same structure, and their purpose is to realize that the slag slowly descends from the top so as to fully receive the airflow drying effect. For ease of description, the first conveyor belt units 4.3 and the second conveyor belt units 5.3 are collectively referred to as conveyor mesh belts, and the space inside the first material hopper 4 and the second material hopper 5 is defined as the drying chamber.

[0039] The conveyor belts are arranged vertically at intervals within the drying chamber, and multiple conveyor belts are staggered in height so that the falling part of the upper conveyor belt is directly opposite the receiving part of the lower conveyor belt. As a result, the residue will fall down step by step along the conveyor belts. The conveying surfaces of the first conveyor belt unit 4.3 and the second conveyor belt unit 5.3 are both provided with mesh holes for airflow. Thus, the multi-layered conveyor belts extend the drying path of the residue, and the mesh hole design promotes airflow penetration.

[0040] Furthermore, an air outlet unit can be configured inside the conveyor belt to further improve the drying effect of the airflow on the residue. This is a common technology in some baking and automation fields, and it is only necessary to integrate the air outlet unit inside the conveyor belt. We will not go into too much detail here.

[0041] Inside the first material hopper 4, the second feeding unit 4.2 and the first conveyor belt unit 4.3 receive airflow from the cold air unit 4.1 and the hot air unit 5.1. The second feeding unit 4.2 can be a vertically arranged screw, and its outer casing can be equipped with a mesh jacket to prevent residue from falling off while ensuring airflow. Thus, the residue undergoes a second vertical stroke inside the first material hopper 4, preventing the outer shell of the residue from hardening excessively and ensuring a more uniform moisture content.

[0042] Inside the second material hopper 5, the second conveyor belt unit 5.3 ensures that the hot air acts fully on the residue. Furthermore, thanks to the cold air in the first material hopper 4, the surface pores of the residue are made uniform, thereby improving the drying efficiency. The dry residue outlet 5.2 at the bottom of the second material hopper 5 is equipped with a third feeding unit 10.5. This third feeding unit 10.5 can be a hydraulic push rod to force the residue to be shaped at the dry residue outlet 5.2, or it can be equipped with a screw conveyor or other feeding components to send the dry residue out.

[0043] To ensure that the third feeding unit 10.5 fully exerts its effect on the residue at the bottom of the second material bucket 5, the bottom of the second material bucket 5 is preferably designed with a constricted opening to guide the residue to fall, and the constricted opening at the bottom matches the outer diameter of the third feeding unit 10.5.

[0044] In the above embodiments, in order to fully utilize the combined effect of hot and cold airflows in the first material barrel 4 and the second material barrel 5, the second feeding unit 4.2, cold air unit 4.1, and first conveyor belt unit 4.3 in the first material barrel 4, and the hot air unit 5.1 and second conveyor belt unit 5.3 in the second material barrel 5 can be time-controlled to at least ensure that the residue entering the first material barrel 4 can be affected by the cold air.

[0045] Preferably, a fermentation agent is placed in the second feed hopper 5. Specifically, it can be set as a timed dispenser to control the fermentation variables. This dispenser is similar to a timed pet food dispenser, which is an existing product and will not be described in detail here.

[0046] Combination Figure 6 and Figure 8 , Figure 9 As shown, as a further embodiment of the air passage 7, the air passage 7 specifically refers to all airflow pipes connecting the first material tank 4, the second material tank 5 to the clean water chamber 6.2.

[0047] Since the air passage delivers the hot flow from the second material tank 5 to the clean water chamber 6.2 and then discharges it, it is preferable to provide an activated carbon unit 7.1 in the air passage 7. The activated carbon unit 7.1 can be set on the air outlet side of the first material tank 4 to perform preliminary filtration of the air discharged from the first material tank 4 and remove some odors and impurities. Alternatively, it can be set on the air inlet side of the clean water chamber 6.2 to further purify the hot flow and prevent the water flow output from the return passage 8 from carrying odors and affecting the user experience.

[0048] Of course, activated carbon unit 7.1 can also be replaced with other deodorizing devices.

[0049] Temperature and flow sensors can also be installed in the air passage 7. The temperature sensor monitors the temperature of the heat flow within the air passage 7 in real time, allowing for adjustments to the operating parameters of the hot air unit 5.1 and the cold air unit 4.1 based on actual conditions, ensuring drying efficiency and energy utilization. The flow sensor monitors the heat flow rate, ensuring smooth and stable operation of the entire air passage 7. If abnormal flow occurs, an alarm can be issued promptly, prompting the user to check for equipment malfunctions. Furthermore, the pipes in the air passage 7 can be wrapped with insulation material to reduce heat loss during transport, improving energy efficiency. Pipe connections should be properly sealed to prevent heat leakage and ensure the normal operation of the entire system.

[0050] Specifically, the air passage 7 includes an exhaust section 7.3 and an air inlet section 7.2. The air passage 7 following the water purification chamber 6.2 is defined as the exhaust section 7.3, and the air passage 7 preceding the water purification chamber 6.2 is defined as the air inlet section 7.2. The air inlet section 7.2 is located at the output port of the exhaust unit. The exhaust section 7.3 connects to the air inlet section 7.2 from the bottom of the water purification chamber 6.2, and the air outlet of the exhaust section 7.3 extends to the outside of the water purification chamber 6.2 and connects to the sewer. Alternatively, the exhaust section 7.3 and the air inlet section 7.2 are set alternately, with the air inlet section 7.2 delivering hot air to the water purification chamber 6.2 and the exhaust section 7.3 used to guide the gas in the water purification chamber 6.2 to the sewer.

[0051] The air inlet section 7.2 includes an air duct 7.21 located between the top of the first material hopper 4 and the second material hopper 5, and an air inlet pipe 7.22 located between the first material hopper 4 and the clean water chamber 6.2. The exhaust section 7.3 includes an exhaust pipe connected to the sewer. The exhaust unit includes a first fan 7.4 located on the air duct 7.21 and a second fan 7.5 located inside the air inlet pipe 7.22. The activated carbon unit 7.1 is located inside the air inlet pipe 7.22.

[0052] The first fan 7.4 draws hot air from the second material bin 5 into the first material bin 4. Under the action of the cold air unit 4.1 within the first material bin 4, the air is fully utilized at the bottom of the first material bin 4, thus achieving the initial heat utilization of the heat flow and preliminary drying of the residue. Subsequently, the second fan 7.5 draws the preliminarily dried air, along with any small residue particles it may carry, into the clean water chamber 6.2. Inside the clean water chamber 6.2, the activated carbon unit 7.1 deeply purifies the incoming air, removing odors and impurities to ensure the exhaust air is clean and pollution-free. Furthermore, all parts of the air passage 7 are designed for easy disassembly and cleaning, facilitating regular maintenance and ensuring long-term stable operation of the equipment.

[0053] For the water purification chamber 6.2, the airflow entering through the air inlet section 7.2 carries residual heat, which can preheat the water in the water purification chamber 6.2 to a certain extent and improve the energy utilization efficiency. The hot airflow entering is cooled by the water purification chamber 6.2 and then discharged through the exhaust section 7.3.

[0054] like Figure 8 As shown, in one embodiment of the exhaust section 7.3, the air inlet pipe 7.22 is directly connected to the exhaust pipe. In this case, the hot air supplied to the water purification chamber 6.2 preheats the water in the water purification chamber 6.2 through heat exchange. The hot air is then directly discharged to the sewer through the exhaust pipe. The advantage of this method is that it reduces airflow changes in the water purification chamber 6.2 and reduces noise from airflow entering the water purification chamber 6.2. As an optimization of the exhaust section 7.3 in this embodiment, a coil can be installed between the exhaust pipe and the inlet pipe 7.22 inside the water purification chamber 6.2 to increase the heat flow path. The coil is preferably installed at the bottom of the water purification chamber 6.2 to improve the preheating effect of the water purification chamber 6.2.

[0055] like Figure 9As shown, as another implementation of the exhaust section 7.3, the air inlet pipe 7.22 and the exhaust pipe are spaced apart, that is, the air inlet pipe 7.22 and the exhaust pipe are not directly connected. In this case, the hot flow delivered to the water purification chamber 6.2 will directly enter the water purification chamber 6.2. The advantage of this method is that the hot flow can fully act on the water purification chamber 6.2, ensuring that the airflow output to the sewer is a cold airflow. In this embodiment, the water purification chamber 6.2 is preferably set as a closed cavity, and the exhaust pipe is set at the top of the water purification chamber 6. Only the water inlet for receiving the oil-water separator 6 and the return port for discharging to the return flow path 8 are allowed. Of course, a water supply port 6.23 that allows external water sources to enter can also be set. Importantly, the water supply port 6.23, the water inlet and the return port are preferably equipped with one-way valves. The purpose is to prevent the hot flow or the airflow that still has an odor from flowing back into the user's operating environment. However, if the arrangement of the activated carbon unit 7.1 in the air inlet pipe 7.22 is sufficient, it is possible to consider not to set a one-way valve.

[0056] from Figure 8 and Figure 9 As can be seen from this, as a further explanation of the oil-water separation box 6, its purpose is to receive the oil-water mixture from the preceding processing device through the receiving chamber 6.1, and let it settle and separate into layers. The purified water after settling and separating is discharged into the purified water chamber 6.2. The bottom of the receiving chamber 6.1 is provided with a drain port 6.4 to discharge the settled oil, and the top of the receiving chamber 6.1 is provided with an oil outlet 6.5 to discharge the usable oil at the top.

[0057] Specifically, the water purification chamber 6.2 is equipped with a first heating unit 6.21 and a first pump unit 8.36.22. The first heating unit 6.21 provides hot water to the return pipe, and the first pump unit 8.36.22 is arranged in the return flow path 8 and draws purified water from the water purification chamber 6.2. Preferably, the first heating unit 6.21 is located at the bottom of the water purification chamber 6.2. The return flow path 8 includes a return pipe located in the water purification chamber 6.2, which is connected to the first outlet pipe 8.1 and the second outlet pipe. The first pump unit 8.36.22 is located on the return pipe. Through the above improvements, the first heating unit 6.21 provides hot water return, which can dissolve oil stains and improve the cleaning efficiency of the pre-filter tank 1 and the garbage disposal unit 2; the first pump unit 8.36.22 ensures stable delivery of purified water and avoids flushing failure due to insufficient water pressure.

[0058] As a further improvement to the water purification chamber 6.2, a water inlet 6.23 connected to an external water source is also provided in the water purification chamber 6.2. The water inlet 6.23 is opened when there is insufficient water in the water purification chamber 6.2 to ensure that the water volume in the water purification chamber 6.2 is sufficient to carry out a flushing process on the pre-filter tank 1 and the water tank 9.1. To a certain extent, users do not need to actively clean the pre-filter tank 1, and the self-cleaning of the pre-filter tank 1 can be completed through the return flow path 8.

[0059] In addition, a temperature controller 6.24 is installed on the exhaust section 7.3. When the temperature of the airflow output from the exhaust section 7.3 is detected to be high, it can be determined that there is insufficient residual water in the water purification chamber 6.2, or that the temperature of the residual water in the water purification chamber 6.2 has reached the threshold. At this time, the first pump unit 8.36.22 is started to flush the primary filter tank 1 and the water tank 9.1. At the same time, the water inlet 6.23 is started to replenish water to ensure that there is residual water in the water purification chamber 6.2.

[0060] As a further explanation of the overflow plate and overflow area, the oil-water inlet 6.3 is located on the side of the receiving chamber 6.1 and the overflow plate away from the clean water chamber 6.2, wherein there are multiple overflow plates and overflow areas.

[0061] Specifically, the receiving chamber 6.1 is provided with a first overflow plate 6.11, a second overflow plate 6.12 and a third overflow plate 6.13 along the oil-water flow direction; The top of the first overflow plate 6.11 and the top wall of the corresponding receiving chamber 6.1 define the first overflow port 6.14, and the oil-water inlet 6.3 extends to below the first overflow port 6.14; The bottom of the second overflow plate 6.12 and the bottom of the receiving chamber 6.1 define a second overflow port 6.15. The top of the third overflow plate 6.13 and the corresponding top wall of the receiving chamber 6.1 define a third overflow port 6.16. The second overflow port 6.15 is located below the first overflow port 6.14, and the third overflow port 6.16 is located above the second overflow port 6.15. The first overflow plate 6.11 defines a first overflow area on the side close to the oil-water inlet 6.3, defines a second overflow area between the first overflow plate 6.11 and the second overflow plate 6.12, and defines a third overflow area on the side of the third overflow plate 6.13 away from the oil-water inlet 6.3.

[0062] In this embodiment, the oil-water mixture can be fully settled and stratified within the receiving chamber 6.1 by the multi-stage overflow plates. The mixture entering through the oil-water inlet 6.3 first passes over the first overflow plate 6.11 and undergoes initial sedimentation in the first overflow area. Heavier oil and impurities begin to sink, while lighter oil and water continue to flow into the second overflow area through the first overflow port 6.14. Under the action of the second overflow plate 6.12, further stratification occurs, with more oil depositing at the bottom and clean water gradually rising. As the liquid level gradually rises, the relatively clear water at the top flows over the third overflow plate 6.13 into the third overflow area. Finally, the water flows over the second overflow plate 6.12 and the third overflow plate 6.13, and through the third overflow port 6.16 above the second overflow port 6.15 into the third overflow area. Under the action of the third overflow plate 6.13, oil and water are separated relatively thoroughly. Usable oil at the top of the second overflow area is discharged through the oil outlet 6.5, and oil sludge at the bottom is cleaned periodically through the drain port 6.4. The clean water is discharged into the clean water chamber 6.2 for further treatment. This process extends the oil-water residence time, improves the oil-water-sludge stratification accuracy, and reduces intermediate layer mixing. This not only improves the efficiency of oil-water separation but also ensures the quality of the discharged clean water and reduces environmental pollution.

[0063] The drain outlet 6.4 can be connected to a corresponding pipe to guide the oil sludge into a dedicated collection box 5.4 for subsequent treatment. The oil outlet 6.5 is generally located at the top of the receiving chamber 6.1 near the oil layer. Through reasonable structural design, the usable oil at the top can flow out smoothly. The oil outlet 6.5 can also be equipped with a corresponding control valve to control the discharge volume and discharge time according to actual needs. In addition, to achieve better oil-water separation, some auxiliary structures can be set inside the receiving chamber 6.1. For example, some inclined guide plates can be set inside the receiving chamber 6.1 to guide the oil-water mixture to flow along a specific path, increasing the oil-water separation time and efficiency; or some filter screens can be set inside the receiving chamber 6.1 to further filter out fine impurities in the oil-water mixture, improving the quality of the separated purified water and usable oil.

[0064] Furthermore, as a further improvement to the receiving chamber 6.1, a second heating unit 6.6 and a level mirror are provided in the second overflow area. The function of the second heating unit 6.6 is to appropriately heat the oil-water mixture in the second overflow area to improve the efficiency of oil-water separation, especially at low ambient temperatures, where heating can reduce the viscosity of oil and water, making it easier for oil and water to separate. The level mirror is installed on the side wall of the receiving chamber 6.1, and its position facilitates observation of the liquid level in the second overflow area. Users can intuitively understand the progress of oil-water separation and the liquid level in the receiving chamber 6.1 through the level mirror, so as to perform corresponding operations in a timely manner, such as draining oil or purifying water.

[0065] Furthermore, a clean water discharge pipe is provided in the third overflow area, which connects to the clean water chamber 6.2.

[0066] Reference Figure 7 As shown, as another embodiment of the intermediate processing device, the difference from the above embodiment is that the intermediate processing device further includes a screening tank 10, which is used to receive paste-like residue with a low oil-water ratio, and further separate the oil and water in the paste-like residue, perform secondary separation on the paste-like residue, further extract residual oil and water, and reduce the oil content of the final dry residue.

[0067] The input side of the screening barrel 10 is provided with a first oil-water input pipe 10.1 connected to the material distribution path of the material distribution channel 3, and a second oil-water input pipe 10.2 connected to the bottom of the primary filter tank 1. Therefore, the first oil-water input pipe 10.1 is specifically located at the bottom of the horizontal material distribution channel 3. The output side of the screening barrel 10 is provided with a residue output pipe 10.3 connected to the first material barrel 4, and an oil-water output pipe 10.4 connected to the receiving chamber 6.1 connected to the oil-water separation box 6. The oil-water output pipe 10.4 is equipped with a sewage pump 10.6, which is used to pump oil and water to the receiving chamber 6.1.

[0068] The preferred mesh size of the screen 1.1 in the primary filter tank 1 is 40 to 50 mesh, and the diameter of the screen 1.1 is 60 filaments. The outer diameter of the sieve barrel 10 can be 30 cm, and the mesh gap inside it is 60 mesh with a mesh diameter of 30 filaments.

[0069] Combination Figure 10 The workflow of this invention: Primary filter 1 separates and initially removes surface moisture and free grease from kitchen waste: Kitchen waste enters the primary filter tank 1 through the dumping opening. The 40-50 mesh screen 1.1 achieves solid-liquid separation under the vibration of the auxiliary material distribution unit 1.2 or the action of the conveyor belt. The free oil and water enter the lower screening tank 10 through the screen holes. The separated residue enters the garbage processor 2 through the discharge opening. Subsequently, the first pump unit 8.36.22 is started, and the return clean water from the clean water chamber 6.2 continuously washes the screen 1.1 and the water tank 9.1 to prevent the holes from clogging and to help the residue enter the garbage processor 2 for crushing.

[0070] Garbage disposer 2-stage shredding: Solid residue enters the waste processor 2, where the crushing process generates a mechanical squeezing effect, further releasing bound water and grease. At the same time, the overall surface area of ​​the crushed residue increases, which is beneficial for subsequent oil-water separation.

[0071] Material distribution channel 3: extrusion separation After being crushed by the garbage processor 2, the slag enters the distribution channel 3. Under the action of the screw extrusion of the auger, the slag is squeezed, and the residual oil and water are further separated. The squeezed oil and water mixture enters the screening bucket 10, while the relatively dry slag after being squeezed continues to move forward along the distribution channel 3 and is guided to the top of the first bucket 4.

[0072] The screening tank 10 performs a fine treatment: It receives the low-oil-water ratio paste-like residue from the bottom of the distribution channel 3 and the primary filter tank 1. Through internal vibration and wire mesh structure, the paste-like residue undergoes secondary separation. Under vibration, the oil and water in the residue further precipitate out and flow into the bottom of the screening tank 10 through the gaps in the wire mesh, and then into the oil-water separation box 6 for further oil-water separation. The relatively dry residue is then transported to the first material tank 4 by the fourth distribution unit, such as a vertically arranged screw.

[0073] First material tank 4 cold air pretreatment: The first material bin 4 receives relatively dry residue from the distribution channel 3 and paste-like residue from the screening bin 10. At this time, the cold water unit is activated. Under the action of the cold air unit 4.1 inside the first material bin 4, the cold air flow fully acts on the residue at the bottom of the first material bin 4, achieving preliminary drying of the residue. At the same time, the first conveyor belt unit 4.3 slowly transports the residue. The residue passes through the transverse path of the conveyor belt unit and the vertical path of the first material bin 4, and then passes through the vertical path of the first material bin 4 again through the second distribution unit. During this process, the moisture content of the initially dried residue decreases, and its texture becomes relatively loose, facilitating subsequent processing. Furthermore, the cold air pretreatment reduces residue adhesion caused by excessive moisture during later processing, improving the efficiency and stability of the entire process.

[0074] Second material hopper 5 hot air final drying: The second feed tank 5 receives the residue from the first feed tank 4 after preliminary drying. At this time, the hot air unit 5.1 inside the second feed tank 5 is activated, generating hot air and simultaneously adding a fermentation agent. The hot air circulates within the second feed tank 5, exchanging heat thoroughly with the residue, further evaporating the remaining moisture and achieving final drying. The residue after final drying has extremely low moisture content and a loose texture, facilitating subsequent storage, transportation, and further processing. Simultaneously, some of the hot air generated in the second feed tank 5 is drawn back into the first feed tank 4, accelerating the release of some moisture from the residue and achieving the recycling of thermal energy.

[0075] Finally, the dried residue at the bottom of the second hopper 5 will be pushed out to the collection box 5.4 by the third feeding unit 10.5.

[0076] Air passage 7 handles heat flow: The first blower 7.4 draws the hot air from the second material tank 5 into the first material tank 4. Then, the second blower 7.5 draws the hot air from the first material tank 4 into the water purification chamber 6.2. The hot air will pass through the activated carbon unit 7.1 for deodorization. After entering the water purification chamber 6.2, the hot air is heated. If the temperature of the water purification chamber 6.2 is insufficient, the first heating unit 6.21 is turned on. If the temperature of the water purification chamber 6.2 is too high or the remaining water is insufficient, tap water is added. Then, the purified water in the water purification chamber 6.2 rinses the primary filter tank 1 and the water tank 9.1.

[0077] It is worth mentioning that this closed-loop processing not only improves energy efficiency but also ensures the cleanliness and efficient operation of the entire integrated kitchen waste sorting device. The water purification chamber 6.2, as a key component in the closed loop, not only serves as a heat-assisted heating source and stores purified water, but also, through the cooperation of the first heating unit 6.21 and the first pump units 8.3 and 6.22, achieves hot water recirculation, significantly improving the cleaning efficiency of the pre-filter tank 1 and the waste processor 2. Simultaneously, the water inlet 6.23 ensures sufficient water volume in the water purification chamber 6.2, guaranteeing a complete rinse of the pre-filter tank 1 and the water tank 9.1 even under continuous operation, reducing the need for manual intervention and enhancing the automation level of the device.

[0078] (Cloud control) like Figure 11 As shown, as a further improvement, the primary filter tank 1, garbage processor 2, material distribution channel 3, first material bucket 4, second material bucket 5 and oil-water separator 66 in the above embodiment can all be defined as garbage processing units, and also include a smart cloud control system for monitoring and controlling the garbage processing units. The intelligent cloud control system includes: Multiple sensors are installed on the aforementioned waste treatment units to monitor temperature, pressure, flow rate, and weight parameters in real time. The local controller connects to the sensors and is used to receive sensor data and control the operation of various components. The cloud server communicates with the local controller via a wireless network to store data, analyze processing efficiency, generate operation and maintenance reports, and remotely monitor and adjust system parameters through user terminals; The intelligent cloud control system is also equipped with an early warning module. When sensor data is abnormal, the early warning module sends alarm information to the user terminal through the cloud server and automatically adjusts the equipment operating status.

[0079] By monitoring key parameters in real time through multiple sensors, the cloud server analyzes the data and generates operation and maintenance reports. The early warning module automatically adjusts equipment operation or sends alarms when abnormalities occur, realizing unmanned intelligent management and significantly reducing maintenance costs.

[0080] Specifically, the sensors include: The weight monitoring module includes weighing sensors installed at the bottom of each component of the waste treatment unit to monitor the weight of materials in each component in real time. The pipeline unobstructed flow monitoring module includes a non-contact flow sensor and a differential pressure sensor installed inside the oily pipeline to detect the unobstructed cross section of the pipeline; The dry slag collection and monitoring module includes a weight sensor installed at the dry slag outlet 5.2 and a material level sensor inside the dry slag collection bucket, used to monitor the weight of the dry slag discharged and the fullness of the collection bucket; The oil-water separation layer height monitoring module includes a multi-layer liquid level sensor installed in the receiving chamber 6.1, which is used to monitor the height of the bottom layer oil, the middle layer clean water and the upper layer oil and water in real time. In addition, a temperature sensor and a liquid level sensor are also installed in the clean water chamber 6.2. The control unit, connected to each monitoring module, is configured as follows: Analyze the data from the weight monitoring module. When the weight inside the waste treatment unit is detected to be continuously increasing or the single increase exceeds the threshold, the self-cleaning program is triggered. Based on data from the pipeline unobstructed monitoring module, the proportion of unobstructed sections in the pipeline is calculated, and an alarm is triggered when a blockage occurs. Based on the data from the dry residue collection and monitoring module, the weight of the dry residue is calculated and a reminder is given to replace the collection bucket. The oil-water separation layer height monitoring module controls or prompts the oil and water discharge operations of the oil-water separation box 6 based on the data.

[0081] The control unit connects to the cloud server and user terminal via a wireless communication module; the user terminal is a mobile APP that displays data on weight, pipeline patency, dry residue weight, and oil-water layer height in real time, and receives alarm and prompt information.

[0082] The control unit connects to a cloud server via a communication module for data storage and analysis. The user terminal is a mobile app, displaying real-time weight, pipe patency, dry residue weight, and oil-water layer height curves. Alarm information includes residual waste alarms, pipe blockage alarms, and full collection bin alarms. Remote initiation of the self-cleaning function is supported.

[0083] Among them, the weighing sensor of the weight monitoring module is a strain gauge weighing sensor, which is installed on the support feet of the primary filter tank 1, the waste processor 2, the material distribution channel, the first material bucket 4 and the second material bucket 5. The control unit has a preset weight threshold. When it detects that the weight of a component increases beyond the threshold after use, it is determined that there is residual waste. The self-cleaning program is automatically started, and clean water is introduced for rinsing. If the weight does not return to the normal range after self-cleaning, an alarm signal is triggered.

[0084] Specifically, high-precision strain gauge load cells are installed on the bottom support structure of the waste treatment unit. These sensors monitor the weight of materials within each component in real time, and the data is sent to the control unit. The control unit presets a weight threshold; when it detects a continuous increase in weight or a single increase exceeding the threshold, it is determined that residual waste has accumulated. The control unit automatically triggers a self-cleaning program: it opens the clean water valve to flush the relevant components with clean water. After flushing, the weight is weighed again. If the weight still exceeds the threshold, an alarm is issued through the user terminal, prompting manual cleaning. This prevents waste from rotting and emitting foul odors, and extends the equipment's lifespan.

[0085] Among them, the non-contact flow sensor of the pipeline unobstructed flow monitoring module is an ultrasonic flow meter, which is installed on the outer wall of the oily pipeline to measure the flow velocity; Differential pressure sensors are installed at both ends of the pipeline to calculate the unobstructed cross-section based on the pressure difference; the sensor surface is coated with an oleophobic coating to prevent oil contamination and interference.

[0086] Specifically, ultrasonic flow meters are installed on the outer wall of the oil-contaminated pipe to indirectly calculate the unobstructed cross-section by measuring changes in flow velocity. Simultaneously, differential pressure sensors are installed at the pipe inlet and outlet, and the unobstructed proportion is calculated in real time using a model relating the differential pressure data to the theoretical unobstructed cross-section. The sensor surfaces are coated with a polytetrafluoroethylene (PTFE) oleophobic coating to reduce oil adhesion. The control unit periodically scans the data; if the unobstructed cross-section falls below a set threshold, an alarm is triggered and high-pressure flushing is recommended.

[0087] The dry slag collection and monitoring module includes a dynamic weighing module as its weight sensor, located below the dry slag outlet 5.2 of the second hopper 5, to measure the weight of the discharged dry slag in real time. The level sensor is an ultrasonic level gauge, located at the top of the dry slag collection hopper, used to detect the overflow status of the hopper. When overflow occurs, a notification message is sent via the control unit. When the level reaches a set threshold, a notification message is pushed to the user terminal, and the system is paused until the collection hopper is replaced. This helps users optimize the collection frequency and avoid leakage.

[0088] In this embodiment, by integrating monitoring modules for weight, pipelines, dry residue, and oil-water layer height, the entire process is automated for monitoring and intelligent maintenance. Suitable for both residential and commercial environments, it effectively prevents blockages, residues, and inefficient separation. Simultaneously, it enables predictive maintenance of the food waste treatment system, improving reliability and user experience. All monitoring data is traceable, providing a basis for optimizing the processing flow. The system features a high degree of automation, low maintenance costs, and high processing efficiency.

[0089] The sensors mentioned above all demonstrate their own detection function. Their purpose is solely to send sensing information to the control unit to obtain the working information and status of each waste treatment unit. Those skilled in the art can design the sensor placement and communication, which will not be elaborated upon here.

[0090] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
