Description

An integrated treatment device for reducing and dehydrating kitchen waste Technical Field

[0001] This invention relates to the field of kitchen waste treatment equipment technology, and more specifically, to an integrated kitchen waste reduction and dehydration treatment device. Background Technology

[0002] Food waste is a type of waste that exists in every household and restaurant kitchen, especially in large commercial catering kitchens and enterprise kitchens, which generate a large amount of food waste every day. Food waste contains a high amount of moisture and organic matter, making it easy to decompose, produce foul odors, and affect the surrounding environment.

[0003] A search of existing technologies revealed a Chinese patent (publication number CN111359866B) disclosing a kitchen waste processing machine, relating to the field of kitchen waste processing technology. The machine includes: a housing with an inlet for accepting kitchen waste; a crushing component disposed within the housing, the crushing component including a crushing chamber having an inlet communicating with the inlet and a discharge outlet for discharging crushed waste residue; and a compression component having a compression chamber communicating with the discharge outlet. The compression component is used to compress the crushed kitchen waste discharged into the compression chamber. This invention provides a kitchen waste processing machine that can crush and compress kitchen waste, resulting in a small volume of processed kitchen waste, facilitating cleaning, storage, and recycling as fertilizer.

[0004] The aforementioned patent documents and existing technologies reveal that food waste treatment equipment often suffers from low space utilization and integration, as well as limited functionality. This makes it difficult to achieve continuous automated processing of crushing, dewatering, volume reduction, and packaging. More significantly, when processing food waste with high moisture and organic matter content, the solid-liquid separation interface of existing dewatering devices—the dynamic contact area between the spiral pusher and the mesh filter—is highly susceptible to the adhesion and accumulation of organic residue. This residue, continuously accumulating in a humid environment, provides a breeding ground for microbial growth, ultimately forming a stubborn biofilm (a type of derivative solid waste). This biofilm not only becomes a secondary source of pollution requiring treatment but also clogs the dewatering channels, leading to a continuous decline in dewatering efficiency and severely hindering waste reduction and stabilization. Furthermore, the long-term presence of the biofilm exacerbates odor emissions and pathogen growth, ultimately making it difficult for the entire machine to meet the environmental protection technical requirements for hygienic, efficient, continuous treatment and resource utilization of solid waste.

[0005] Therefore, this application proposes an integrated treatment device for reducing and dehydrating kitchen waste to solve the above problems. Summary of the Invention

[0006] Technical problems to be solved: In view of the problems existing in the prior art, the purpose of this invention is to provide an integrated treatment device for reducing and dehydrating kitchen waste, which solves the problems of low space utilization and integration of existing kitchen waste treatment equipment, single function and difficulty in achieving continuous automated treatment, and inability to effectively treat the biological layer generated by high water content and high organic matter waste, which leads to secondary pollution, reduced dehydration efficiency and breeding of odor and bacteria, ultimately failing to meet the requirements of environmental protection treatment and resource utilization.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an integrated treatment device for reducing and dehydrating kitchen waste, comprising an integrated cabinet, a working platform installed on the top of the integrated cabinet, and a feeding funnel installed on the working platform. The integrated cabinet has a solid discharge port at its lower part, and a crushing component for receiving the material discharged from the feeding funnel is installed inside the integrated cabinet. A dehydration cylinder for solid-liquid separation is provided inside the integrated cabinet, and the feeding end of the dehydration cylinder is connected to the discharge port of the crushing component. A mesh filter ring rotates inside the dehydration cylinder, and a hollow discharge shaft rotates in the middle of the dehydration cylinder. A squeezing spiral blade is installed on the outer wall of the hollow discharge shaft. An aeration and dewatering component is provided inside the hollow discharge shaft. The aeration and dewatering component includes a sleeve column fixed to the outer wall of the hollow discharge shaft and two rows of aeration ports symmetrically and equidistantly arranged on the outer wall of the sleeve column. When the hollow discharge shaft rotates, it drives the aeration ports to spray high and low airflows circumferentially, destroying and cleaning the biofilm and organic solid waste residue attached to the inner surface of the mesh filter ring.

[0008] In a new embodiment, an air supply assembly for providing air to the aeration ports is installed inside the sleeve. The air supply assembly includes a three-way pipe and two straight pipes. The three-way pipe is installed inside the sleeve, and the two air outlets of the three-way pipe are respectively connected to the straight pipes. Each straight pipe is provided with multiple fan-shaped nozzles. The fan-shaped nozzles on the two straight pipes are embedded in the corresponding aeration ports and located in the interval area between two adjacent extrusion spiral blades. The fan-shaped nozzles of the two straight pipes are respectively inclined upward and downward, so that when the hollow discharge shaft rotates, the fan-shaped nozzles on both sides form a complementary scanning airflow that disrupts the adhesion environment on the inner surface of the mesh filter ring.

[0009] In a new embodiment, the air inlet end of the three-way pipe is embedded in the lower shaft of the hollow discharge shaft and extends to the outside to connect to the rotary joint. The rotary joint is sequentially connected to the pulse air valve, the air tank and the air compressor pump through the air supply pipe. The air tank and the air compressor pump are installed on the rear inner wall of the integrated cabinet.

[0010] In a new embodiment, a dewatering cylinder is mounted on the side wall of the integrated cabinet via an assembly table. A power unit is mounted on the assembly table. The power unit uses a drive motor, pulleys, and belt to drive the mesh filter ring and the hollow discharge shaft to rotate inside the dewatering cylinder. A drain ring is provided on the lower side of the inner wall of the dewatering cylinder, and a drain pipe is connected to the bottom of the drain ring. A feed cover is installed on the top of the dewatering cylinder, and the middle of the feed cover is rotatably connected to the other end of the hollow discharge shaft. A horn-shaped discharge port is installed at the bottom of the feed cover.

[0011] In a new embodiment, a negative pressure assembly is installed at the bottom of the dehydration cylinder to provide a negative pressure suction space between the dehydration cylinder and the mesh filter ring. The negative pressure assembly includes: a bottom ring cover installed at the bottom of the dehydration cylinder; a rotating ring rotatably installed on the top of the bottom ring cover, with the top of the rotating ring sealingly fitted to the bottom of the dehydration cylinder; and an air extraction ring installed at the bottom of the bottom ring cover. An air extraction pipe is installed on the top of the air extraction ring, and the air extraction pipe is connected to an air extraction pump installed on the rear wall of the integrated cabinet through a pipeline. The air extraction ring is arranged around the outer periphery of the mesh filter ring, and its air extraction action area is set close to the outer surface of the mesh filter ring and maintains a distance from the inner wall of the dehydration cylinder, thereby preferentially extracting the residue splashed from the aeration port on the outer side of the mesh filter ring.

[0012] In a new embodiment, an inclined grid plate is installed on the outer wall of the rotating ring, and a ring frame is installed on the inner wall of the rotating ring. The middle part of the ring frame is fixedly installed on the lower shaft of the hollow discharge shaft. A scraper is installed on the lower rear side of the dewatering cylinder, and the scraper abuts against the inclined surface of the inclined grid plate. An arc-shaped discharge port is installed at the bottom end of the bottom ring cover, and a heating plate is installed on the lower arc surface of the arc-shaped discharge port. A discharge tank is connected to the discharge port of the arc-shaped discharge port.

[0013] In a new embodiment, the outer surface of the inclined grid plate is coated with a wear-resistant and oleophobic material layer, which is a Teflon coating or a ceramic matrix composite coating.

[0014] In a new embodiment, the crushing assembly includes a crushing motor, a crushing disc, and a crushing water blade disc; the crushing motor drives the crushing water blade disc to rotate at high speed to crush the kitchen waste fed from the feed funnel; the crushing disc has a discharge hole on its side for discharging the crushed material into the dewatering cylinder.

[0015] In a new embodiment, the integrated cabinet is further equipped with a dehydration circulation component, which includes a circulating water pump, a circulating water storage tank, and a dehydration recovery pipe. The inlet of the dehydration recovery pipe is connected to a drain pipe, and the outlet is connected to the circulating water storage tank. The inlet of the circulating water pump is connected to the circulating water storage tank, and the outlet of the circulating water pump is connected to the feed funnel through a water delivery pipe.

[0016] Beneficial effects: Compared with the prior art, the advantages of this invention are as follows: 1. This application integrates the crushing component, dewatering cylinder and built-in aeration and desliming component into the same cabinet. The dewatering cylinder integrates spiral lifting and centrifugal dewatering, combined with the dual functions of high-pressure air explosion cleaning. This effectively solves the problems of low integration, insufficient space utilization and inability to achieve continuous automated processing of crushing, dewatering and volume reduction caused by the dispersed structure and single function of traditional equipment. Furthermore, when processing kitchen waste with high moisture content and high organic matter content, it can automatically and thoroughly remove the biofilm solid waste from the mesh filter ring of the dewatering cylinder, maintain the dewatering efficiency of the equipment for a long time, eliminate the growth of odor and bacteria from the source, ensure the quality of the solids after dewatering, and facilitate the subsequent resource utilization of waste.

[0017] When the torque sensor integrated on the control circuit of the drive motor detects an increase in the load of the drive motor, the cleaning process is automatically started after the dehydration cycle ends. The air compressor pump stores compressed air in the air tank, which is discharged by the pulse air valve at a set frequency. The high-pressure gas enters the rotating hollow discharge shaft through the rotary joint, is transported through the built-in three-way pipe and straight pipe, and is finally sprayed out at high speed from the upward and downward inclined fan-shaped nozzles. As the hollow discharge shaft rotates, the fan-shaped airflow formed by the two rows of nozzles scans and impacts the entire inner surface of the mesh filter ring without dead angles, powerfully peeling off the biological film and organic residues attached to it. When the high-pressure airflow impacts the inner surface of the mesh filter ring, it can break through the filter holes and spray some of the blockages and water droplets into the dewatering cylinder cavity outside the filter screen, contaminating the cleaned area and the inner wall of the equipment, causing cross-contamination. To solve this problem, an air extraction ring is installed close to the outside of the mesh filter ring. This ring is connected to an air extraction pump through a pipeline. At the same time as the air is sprayed at the aeration port for cleaning, the air extraction pump starts, creating a high negative pressure zone between the air extraction ring and the outer surface of the mesh filter ring. This instantly removes the dirt and water vapor that have been shaken out and splashed onto the outside of the filter screen by the airflow, thus achieving a synergistic effect of internal blowing and external suction, ensuring that the cleaning process does not cause secondary pollution. Solid residue drawn in by negative pressure will enter the suction ring and contaminate the suction space. To address this issue, a cleaning and collection structure consisting of an inclined grid plate and fixed scrapers is installed at the bottom of the dehydration cylinder. The falling residue falls onto the inclined grid plate driven by the rotating ring. As the rotating ring rotates, the grid plate conveys the residue to the fixed scrapers. The scrapers contact the inclined surface of the grid plate, scraping the residue off the grid gaps. The residue falls into the arc-shaped discharge port at the bottom. The scraped-off wet organic residue is extremely sticky and easily adheres to the inner wall of the discharge port, causing blockage and preventing smooth discharge. Therefore, a heating plate is installed on the lower arc surface of the arc-shaped discharge port, and its outlet is connected to the discharge tank. The residue falling into the arc-shaped discharge port is moderately heated and dried by the heating plate during the sliding process, reducing its surface moisture and stickiness, making it loose and easy to slide, and finally smoothly slides into the sealed discharge tank for storage, awaiting unified cleaning from the solid discharge port.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] This application provides an integrated kitchen waste reduction and dehydration treatment device, which solves the problems of low space utilization and integration of existing kitchen waste treatment equipment, limited functionality making continuous automated treatment difficult, and inability to effectively treat the biofilm solid waste generated by high-moisture and high-organic-content waste, leading to secondary pollution, decreased dehydration efficiency, and the growth of odorous bacteria, ultimately failing to meet environmental protection and resource recovery requirements. In use, this invention utilizes an aeration and dewatering component and a negative pressure component to effectively treat the biofilm solid waste generated when the dewatering device processes high-moisture and high-organic-content waste, avoiding secondary pollution, improving dehydration efficiency, and meeting the environmental protection and resource recovery requirements of kitchen waste.

[0036] The technical solutions in this application are intended to solve the above-mentioned technical problems, and the overall approach is as follows.

[0037] Example 1, please refer to Figures 1-16. This embodiment of the application provides an integrated treatment device for reducing and dehydrating kitchen waste, including an integrated cabinet 1, a working platform 2 installed on the top of the integrated cabinet 1, and a feeding funnel 3 installed on the working platform 2. A solid discharge port 4 is provided at the bottom of the integrated cabinet 1, and a crushing component 5 for receiving the discharge from the feeding funnel 3 is installed inside the integrated cabinet 1. A dehydration cylinder 6 for solid-liquid separation is provided inside the integrated cabinet 1, and the feeding end of the dehydration cylinder 6 is connected to the discharge port of the crushing component 5; inside the dehydration cylinder 6... A mesh filter ring 61 is installed, and a hollow discharge shaft 62 rotates in the middle of the dewatering cylinder 6. An extrusion spiral blade 63 is installed on the outer wall of the hollow discharge shaft 62. An aeration and dewatering assembly 7 is provided inside the hollow discharge shaft 62. The aeration and dewatering assembly 7 includes a sleeve column 71 fixed to the outer wall of the hollow discharge shaft 62 and two rows of aeration ports 72 symmetrically and equidistantly arranged on the outer wall of the sleeve column 71. When the hollow discharge shaft 62 rotates, it drives the aeration ports 72 to spray high and low airflows in a circumferential direction, which destroys and cleans the biological film and organic solid waste residues attached to the inner surface of the mesh filter ring 61.

[0038] Furthermore, the crushing component 5 includes a crushing motor, a crushing disc, and a crushing water blade disc; the crushing motor drives the crushing water blade disc to rotate at high speed to crush the kitchen waste fed from the feed hopper 3; the crushing disc has a discharge hole on its side for discharging the crushed material into the dewatering cylinder 6.

[0039] In the preferred embodiment of this solution, the crushing component 5, the dewatering cylinder 6, and the built-in aeration and desliming component 7 are highly integrated into the integrated cabinet 1. The dewatering cylinder 6 integrates spiral lifting and centrifugal dewatering, combined with the dual functions of high-pressure air explosion cleaning. This effectively solves the problems of low integration, insufficient space utilization, and inability to achieve continuous automated processing of crushing, dewatering, and volume reduction caused by the dispersed structure and single function of traditional equipment. Furthermore, when processing kitchen waste with high moisture content and high organic matter content, it can automatically and thoroughly remove the biofilm from the mesh filter ring 61 of the dewatering cylinder 6 without contaminating the inner wall of the dewatering cylinder 6, thus maintaining the equipment's dewatering efficiency for a long time, reducing energy consumption, eliminating the growth of odors and bacteria from the source, ensuring the quality of the solids after dewatering, and facilitating subsequent waste resource utilization.

[0040] Specifically, the integrated kitchen waste reduction and dehydration treatment device of this application has the following working process: First, kitchen waste is fed into the feeding funnel 3 and falls into the crushing component 5 below it. The crushing motor drives the crushing water blade disc to rotate at high speed, cutting and crushing the waste into a fine particle mixture. The crushed material is discharged through the discharge hole on the side of the crushing disc, and then transported through the pipeline into the feeding end of the dehydration cylinder 6, and enters the hollow discharge shaft 62 of the dehydration cylinder 6, and is discharged through the opening at the bottom of the hollow discharge shaft 62; Second, the hollow discharge shaft 62 is driven to rotate by the drive motor, pulley and belt, and the extrusion screw installed on the hollow discharge shaft 62... The rotary vane 63 rotates accordingly, and simultaneously, the drive motor drives the pulley connected to the mesh filter ring 61 to rotate. The kitchen waste is lifted and compressed upwards by the extruding rotary vane 63, and the centrifugally dehydrated kitchen waste is transported to the funnel discharge port 67 of the dehydration cylinder 6 for discharge. The separated liquid is collected through the drain ring port 64 and discharged through the drain pipe 65, thus achieving the lifting and dehydration treatment of the kitchen waste. It should be noted that the control circuit of the drive motor can integrate a current or torque sensor to monitor the motor's operating resistance in real time and continuously monitor the motor torque. When the detected torque continuously increases and exceeds a preset threshold (indicating that the mesh filter ring 61...), a sensor will be activated. (If the blockage worsens and the motor load increases), the control system (the control panel installed at the front of the integrated cabinet 1) can record the cleaning command. After the current dehydration operation ends naturally, the control system will automatically start the cleaning process again. Third, after the cleaning process starts, the air compressor pump 87 works and fills the air tank 86 with air. The pulse air valve 85 opens and closes at a set frequency, and the high-pressure gas is delivered through the rotary joint 84 and the pipeline in the hollow discharge shaft 62 to the three-way pipe 81 and the two straight pipes 82. The high-pressure gas is finally ejected at high speed from the fan-shaped nozzles 83 that are set to be inclined upwards and downwards respectively. When the hollow discharge shaft 62 rotates, the upper and lower rows of inclined fan-shaped nozzles spray out at high speed. The head 83 rotates accordingly, and the high-pressure airflow it ejects forms a complementary scanning impact, covering and impacting the entire inner surface of the mesh filter ring 61 without dead angles, effectively destroying, peeling off and cleaning the biological mucus and organic solid residues attached to it; Fourth, while the high-pressure gas cleaning operation is underway, the suction pump 94 is started, which forms a negative pressure suction space in the area between the suction ring 93 and the outer surface of the mesh filter ring 61, and quickly extracts the residual dirt and water vapor that have been shaken off by the gas explosion and blown to the outside of the mesh filter ring 61, so as to avoid contaminating the inner wall of the dehydration cylinder 6 and also prevent the residual dirt from flowing back into the mesh filter ring 61 due to the gas explosion, causing secondary pollution;Fifth, the cleaned and fallen residue falls to the bottom of the dewatering cylinder 6. The rotating ring 92 rotates with the hollow discharge shaft 62 via the ring frame 96, and the inclined grid plate 95 on its outer wall rotates accordingly. The scraper 97 installed in the lower middle of the rear of the dewatering cylinder 6 abuts against the inclined surface of the rotated inclined grid plate 95, scraping off the residue hanging on the inclined grid plate 95, causing it to roll down through the arc-shaped discharge port 98. It is then dried using the heating plate inside, and the resulting solid dry residue enters the discharge tank 99 for collection, awaiting subsequent manual periodic cleaning. It should be noted that the separation liquid discharged from the drain pipe 65 can be transported to the circulating water storage tank 102 for temporary storage through the connected dewatering recovery pipe 103. When needed, the circulating water pump 101 can return this water to the feed funnel 3 through the water delivery pipe for wetting materials or rinsing pipelines, realizing the recycling of water resources. The solid waste discharged through the trumpet discharge port 67 is collected by an external garbage bin.

[0041] Please refer to Figures 15-16. An air supply assembly 8 is installed inside the sleeve 71 to provide air to the aeration port 72. The air supply assembly 8 includes a three-way pipe 81 and two straight pipes 82. The three-way pipe 81 is installed inside the sleeve 71. The two air outlets of the three-way pipe 81 are respectively connected to the straight pipes 82. Each straight pipe 82 is provided with multiple fan-shaped nozzles 83. The fan-shaped nozzles 83 on the two straight pipes 82 are embedded in the corresponding aeration port 72 and are located in the interval area between two adjacent extrusion spiral blades 63. The fan-shaped nozzles 83 of the two straight pipes 82 are respectively inclined upward and downward, so that when the hollow discharge shaft 62 rotates, the fan-shaped nozzles 83 on both sides form a complementary scanning airflow to destroy the adhesion environment on the inner surface of the mesh filter ring 61.

[0042] In the preferred embodiment of this solution, two rows of straight pipes 82 located within the sleeve column 71, and fan-shaped nozzles 83 positioned between and on two adjacent extrusion spiral blades 63, tilted upwards and downwards respectively, allow the high-pressure airflow from the two rows of nozzles to form a complementary, scanning impact range when the hollow discharge shaft rotates. This ensures that the high-pressure airflow can fully cover the entire inner surface of the mesh filter ring 61, leaving no blind spots in cleaning. This thoroughly and efficiently destroys and peels off the biofilm and organic residues attached to it, preventing the filter screen of the mesh filter ring 61 from being clogged by biofilm solid waste generated by oil stains, which would lead to a decrease in dewatering efficiency and an increase in equipment load, thus ensuring the continuous and stable operation of the dewatering operation.

[0043] Please refer to Figures 8 and 15. The air inlet end of the three-way pipe 81 is embedded in the lower shaft of the hollow discharge shaft 62 and extends to the outside to connect to the rotary joint 84. The rotary joint 84 is connected to the pulse air valve 85, the air tank 86 and the air compressor pump 87 in sequence through the air supply pipe. The air tank 86 and the air compressor pump 87 are installed on the rear inner wall of the integrated cabinet 1.

[0044] In the preferred embodiment of this solution, a fixed air supply pipe is connected to a rotating hollow discharge shaft 62 via a rotary joint 84. This solves the connection and dynamic sealing issues between the rotating component and the fixed air source, ensuring that high-pressure gas can be continuously, stably, and leak-free delivered to the air supply assembly 8 inside the high-speed rotating hollow discharge shaft 62, guaranteeing the continuous and stable operation of the aeration cleaning function. Secondly, the combination of an air compressor pump 87 and an air storage tank 86 allows for the pre-storage of sufficient compressed air, ensuring that a large volume of high-pressure airflow can be provided at the moment of pulse jet, creating a powerful air explosion effect that effectively breaks down and removes blockages. This avoids the airflow pressure and flow fluctuations that may occur when using a single air pump, significantly enhancing the cleaning power. Furthermore, the control of the pulse valve 85 causes the airflow to be ejected intermittently and instantaneously, rather than continuously. This pulse mode greatly reduces the consumption of compressed air, achieving optimal cleaning results while significantly reducing energy consumption, making it more energy-efficient and environmentally friendly.

[0045] Please refer to Figures 8 and 9. A dewatering cylinder 6 is installed on the side wall of the integrated cabinet 1 via an assembly table. A power unit is installed on the assembly table. The power unit uses a drive motor, two pulleys, and a belt to drive the hollow discharge shaft 62 to rotate inside the dewatering cylinder 6. A drain ring 64 is provided on the lower side of the inner wall of the dewatering cylinder 6. A drain pipe 65 is connected to the bottom of the drain ring 64. A feed cover 66 is installed on the top of the dewatering cylinder 6. The middle of the feed cover 66 is rotatably connected to the other end of the hollow discharge shaft 62. A horn-shaped discharge port 67 is installed at the bottom of the feed cover 66.

[0046] In the preferred embodiment of this solution, a power unit consisting of a drive motor and a belt pulley transmission is used to control the rotation of the mesh filter ring 61 and the hollow discharge port 62, thereby utilizing centrifugal force and lifting action for dewatering and discharge. An annular drainage ring 64 is provided on the lower side of the inner wall of the dewatering cylinder 6, which can collect the squeezed wastewater in a 360-degree manner (in reality, the dewatering cylinder 6 is installed at an angle, and the drainage ring 64 in the lower half plays the main collection role). The wastewater is then centrally discharged through the bottom drainage pipe 65, effectively preventing splashing or accumulation of wastewater inside the equipment, ensuring a clean dewatering working environment, improving drainage efficiency, and allowing the discharged wastewater to be recycled in the subsequent dewatering circulation component 10.

[0047] The top of the dewatering cylinder 6 is sealed by the feed cover 66, and the middle part is rotatably connected to the hollow discharge shaft 62. This design ensures that the crushed kitchen waste can be smoothly introduced into the dewatering cylinder 6 from the crushing component 5, and also achieves dynamic sealing at the rotating shaft, effectively preventing sewage and odor from leaking from the top during the dewatering process. At the same time, the horn-shaped discharge port 67 installed at the bottom of the feed cover 66 forms a gradually narrowing guide channel, which can smoothly guide the dewatered solid waste that is lifted up to be discharged into the external garbage bin.

[0048] Please refer to Figures 5, 12, and 13. A negative pressure assembly 9 is installed at the bottom of the dehydration cylinder 6 to provide a negative pressure suction space between the dehydration cylinder 6 and the mesh filter ring 61. The negative pressure assembly 9 includes: a bottom ring cover 91, installed at the bottom of the dehydration cylinder 6; a rotating ring 92, rotatably installed on the top of the bottom ring cover 91, with the top of the rotating ring 92 sealingly fitting the bottom of the dehydration cylinder 6; and a suction ring 93, installed at the bottom of the bottom ring cover 91. A suction pipe is installed on the top of the suction ring 93, and the suction pipe is connected to a suction pump 94 installed on the rear wall of the integrated cabinet 1 through a pipeline. The suction ring 93 is arranged around the outer periphery of the mesh filter ring 61, and its suction action area is set close to the outer surface of the mesh filter ring 61 and maintains a distance from the inner wall of the dehydration cylinder 6, thereby preferentially extracting the residue splashed from the aeration port 72 on the outer side of the mesh filter ring 61.

[0049] In the preferred embodiment of this solution, a negative pressure environment is created on the outer surface of the mesh filter ring 61 by the suction pump 94. This environment instantly removes residual dirt and moisture that have been broken down, shaken off, and splashed onto the outside of the filter screen by the high-pressure airflow from the aeration port 72, preventing these contaminants from splashing, spreading, or re-adhering inside the dehydration cylinder 6. The suction zone is positioned close to the outer surface of the mesh filter ring 61, forming a high-speed airflow channel that creates a suction and sweeping effect on the outer surface of the filter screen. This not only removes large residues but also removes fine particles that clog the filter pores. The particles, together with the internal air-explosion cleaning, form an internal and external linkage, complementing each other and greatly improving the overall cleaning efficiency and thoroughness. At the same time, the spacing between the suction ring 93 and the inner wall of the dehydration cylinder 6 allows the negative pressure suction force to be prioritized and concentrated on the most critical mesh filter ring 61 area, accurately extracting contaminants here. On the one hand, this avoids the dispersion and waste of suction force, improving energy utilization efficiency and suction effect. On the other hand, it also prevents the contaminants that are splashed and sucked into contact with the inner wall of the dehydration cylinder 6, causing the inner wall contamination problem.

[0050] Please refer to Figures 12 and 13. An inclined grid plate 95 is installed on the outer wall of the rotating ring 92, and a ring frame 96 is installed on the inner wall of the rotating ring 92. The middle part of the ring frame 96 is fixedly installed on the lower shaft of the hollow discharge shaft 62. A scraper 97 is installed on the lower rear side of the dewatering cylinder 6. The scraper 97 abuts against the inclined surface of the inclined grid plate 95. An arc-shaped discharge port 98 is installed at the bottom end of the bottom ring cover 91. A heating plate is installed on the lower arc surface of the arc-shaped discharge port 98. The discharge port 98 is connected to a discharge tank 99.

[0051] Furthermore, the outer surface of the oblique grid plate 95 is coated with a wear-resistant and oleophobic material layer, which is a Teflon coating or a ceramic matrix composite coating.

[0052] In the preferred embodiment of this solution, the rotating ring 92 rotates synchronously with the hollow discharge shaft 62 via the ring frame 96, causing the inclined grid plate 95 on its outer wall to rotate synchronously. The stationary scraper 97 continuously contacts the inclined surface of the rotating grid plate 95, effectively scraping off the residue carried on the grid plate and detached from the filter screen, thus achieving automatic cleaning and collection and preventing the grid plate pores from being blocked. At the same time, the scraped residue eventually falls into the arc-shaped discharge port 98 at the bottom. The heating plate installed on the lower arc surface of the discharge port can lightly heat and dry the residue, effectively reducing its surface moisture and stickiness, significantly preventing the adhesion, accumulation and blockage of moist organic matter on the inner wall of the discharge port, ensuring the long-term unobstructed discharge channel, and finally entering the discharge tank 99 at the discharge port 98 for storage, awaiting regular cleaning by the staff.

[0053] The Teflon or ceramic-based composite coating has extremely low surface energy and non-stick properties, effectively preventing damp and greasy kitchen waste residue from adhering to the surface of the inclined grid plate 95. This allows the residue scraped off by the scraper 97 to slide more smoothly and thoroughly into the arc-shaped discharge port 98, greatly reducing residue on the surface of the inclined grid plate 95 and avoiding the risk of clogging the grid gaps of the inclined grid plate 95 due to residue accumulation. Maintaining the cleanliness of the surface of the inclined grid plate 95 and the unobstructed passage is the key to maintaining the negative pressure suction effect. By preventing residue from clogging the grid gaps, this coating ensures the long-term unobstructed flow of the negative pressure airflow channel, thereby ensuring the continuous and stable suction efficiency of the suction ring 93 and indirectly improving the reliability of the entire cleaning system.

[0054] Please refer to Figure 6. The integrated cabinet 1 is also equipped with a dehydration circulation component 10, which includes a circulating water pump 101, a circulating water storage tank 102, and a dehydration recovery pipe 103. The inlet of the dehydration recovery pipe 103 is connected to the drain pipe 65, and the outlet is connected to the circulating water storage tank 102. The inlet of the circulating water pump 101 is connected to the circulating water storage tank 102, and the outlet of the circulating water pump 101 is connected to the feed funnel 3 through a water delivery pipe.

[0055] In a preferred embodiment of this solution, the wastewater separated by compression is collected in a circulating water storage tank 102 through the dewatering recovery pipe 103, and can be reused in the feeding funnel 3 by the circulating water pump 101 as wetting or rinsing water for wet waste, forming a closed-loop water resource recycling system. This greatly reduces the consumption of fresh tap water and achieves the goal of energy conservation and environmental protection. At the same time, additional purification devices such as filters, oil-water separators, or sterilizers can be added to the inlet or outlet of the circulating water storage tank 102 for purification treatment, thereby achieving better secondary utilization. Secondly, the reused water can pre-wet the kitchen waste fed into the feeding funnel 3, making it easier for the blade of the crushing component 5 to cut and crush, reducing the load and wear of the blade, and helping to form a more uniform slurry material, which is conducive to the smooth progress of the subsequent dewatering process.
