Description

Technical Field

[0001] This utility model relates to the field of kitchen waste treatment technology, specifically to a modular kitchen waste resource recovery treatment device. Background Technology

[0002] With the rapid development of the social economy, the amount of urban food waste is increasing day by day. Driven by relevant policies, the demand for treatment is also growing, resulting in a continuous increase in the number of food waste treatment projects in various regions.

[0003] Traditional food waste treatment projects require site selection and plant construction, involve complex equipment, require secondary modifications during installation, and have lengthy workshop structure construction time, resulting in significant upfront costs. They are also not easily replicable. In addition, excessively large plant areas lead to land waste, dispersed indoor process layouts, and secondary pollution during food waste transfer. Therefore, food waste treatment projects urgently need a modular treatment equipment that can be deployed quickly, save costs, and is not limited by site conditions.

[0004] Meanwhile, existing modular food waste processing equipment typically requires a crusher to shred food waste into small particles. The crusher's interior contains a screen for screening the food waste. This screen, usually 5-10 mm thick, is made of corrosion-resistant steel plate with perforated screen holes. Over time, the screen surface easily accumulates unpassed waste residue, causing screen blockage. This blockage leads to poor material discharge, resulting in repeated circulation of food waste within the crusher and reduced production capacity. Furthermore, the undischarged food waste repeatedly rubs against the crusher's blades, shortening their lifespan. Therefore, workers need to regularly inspect the screen... The screen needs to be cleaned regularly. When cleaning the screen, workers need to remove it from the casing and use methods such as vibration and backflushing to clean the debris inside the screen holes. After long-term use, the screen is prone to deformation due to metal fatigue. Screen deformation can cause the screen holes to expand or shrink in some areas. Some debris is discharged without being fully shredded, while debris is retained in other areas due to blockage, resulting in a decrease in the consistency of the crusher's output. Therefore, when cleaning the screen, workers need to check whether the screen is deformed. In the existing technology, the work of disassembling and assembling the screen and checking whether the screen is deformed cannot be carried out at the same time. Workers can only check the screen after removing it from the crusher, which increases the workload of the workers. Utility Model Content

[0005] The purpose of this utility model is to provide a modular kitchen waste resource recovery and treatment device to solve the problems mentioned in the background art above:

[0006] 1. The existing kitchen waste recycling equipment has a dispersed indoor process layout, which can cause secondary pollution during the transfer of kitchen waste;

[0007] 2. The existing food waste recycling equipment cannot check whether the screen is deformed while disassembling and assembling the screen, which increases the workload of workers.

[0008] To achieve the above objectives, the present invention aims to provide a modular kitchen waste resource recovery equipment, including a skid-mounted device, wherein the skid-mounted device includes:

[0009] The pretreatment unit includes a crusher and a screw press dewatering machine. The crusher is used to shred the kitchen waste. The discharge port of the crusher is connected to the inlet of the screw press dewatering machine. The screw press dewatering machine is used to dewater the shredded kitchen waste. The screw press dewatering machine is equipped with a discharge pipe and a water outlet pipe. The screw press dewatering machine discharges the dewatered kitchen waste through the discharge pipe and discharges the kitchen waste extrusion liquid through the water outlet pipe, thereby completing the pretreatment of the kitchen waste.

[0010] An oil-water separation unit is installed in the subsequent processing flow of the screw press dewatering machine to separate the oil, water and sludge residue from the extruded liquid of kitchen waste and collect the separated oil.

[0011] The aerobic fermentation and exhaust gas treatment unit includes an aerobic fermentation chamber and a UV photolysis machine. The kitchen waste dehydrated by the screw press dewatering machine is transported to the interior of the aerobic fermentation chamber by a vertical elevator. The oil-water separation unit transports the separated sludge residue to the interior of the aerobic fermentation chamber and mixes it with the kitchen waste for composting and fermentation. The UV photolysis machine is used to deodorize the gas emitted from the aerobic fermentation chamber.

[0012] The wastewater treatment unit is used to sequentially filter, biochemically treat, and further treat the water separated by the oil-water separation unit to treat the wastewater to meet national discharge standards.

[0013] As a further improvement to this technical solution, the crusher includes a hollow shell that runs vertically through the interior. Inside the shell, two symmetrical shredding rollers are horizontally rotatably arranged. On one side of the shell, a drive assembly is provided to drive the two shredding rollers to rotate in opposite directions. Inside the shell, below the shredding rollers, a screen is provided, and the screen holes on the screen physically filter the kitchen waste.

[0014] As a further improvement to this technical solution, a first slot is provided on one side of the housing, and an inspection port is provided on the other side of the housing. An assembly plate is provided inside the inspection port and fixed to the housing by bolts. A second slot is provided on the assembly plate at a position corresponding to the first slot. The two sides of the screen are respectively inserted into the first slot and the second slot. The first slot and the second slot provide support for the two sides of the screen, so that the screen can be stably placed inside the housing.

[0015] As a further improvement to this technical solution, an end plate is provided on the side of the assembly plate away from the housing. One end of the screen is fixed to the end plate by bolts. Two baffles are symmetrically and rotatably arranged on one side of the housing above the inspection port. When the end plate contacts the assembly plate, the baffle is in a vertical state and the lower end of the baffle contacts the side of the end plate away from the assembly plate. The baffle and the assembly plate cooperate to prevent the end plate and the screen from moving laterally, thereby fixing the screen inside the housing.

[0016] As a further improvement to this technical solution, the pretreatment unit also includes a feed hopper for filtrate treatment of kitchen waste, a primary screw conveyor, a manual sorting platform for picking out inorganic materials from the kitchen waste, and a secondary screw conveyor. The primary screw conveyor is used to transport the kitchen waste after filtrate treatment from the feed hopper to the manual sorting platform, and the secondary screw conveyor is used to feed the kitchen waste after inorganic materials have been picked out into the crusher, so as to avoid damage to the crusher due to crushing harder inorganic materials.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This modular kitchen waste resource recovery equipment greatly simplifies the on-site installation process through its skid-mounted design. The entire equipment is factory-tested, and only pipeline and electrical connections need to be completed on-site, thereby shortening the construction cycle. At the same time, the indoor process flow of the skid-mounted equipment, such as the pretreatment unit, oil-water separation unit, aerobic fermentation and waste gas treatment unit, and sewage treatment unit, is centrally arranged, avoiding secondary pollution of kitchen waste during transportation.

[0019] 2. This modular kitchen waste recycling equipment pulls the end plate away from the shell, causing the end plate to move the screen synchronously. If the screen can be successfully pulled out of the shell through the second slot during this process, the disassembly of the screen is completed. At the same time, it is determined that the screen has not undergone serious deformation that would affect screening. If the movement of the screen is blocked by the second slot, it is determined that the screen has undergone serious deformation. This allows for the simultaneous disassembly and assembly of the screen and the inspection of whether the screen is deformed, saving the workload of workers. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figure 1 , Figure 2 and Figure 7As shown, one of the objectives of this embodiment is to provide a modular kitchen waste resource recovery equipment, including a skid-mounted unit 1. The skid-mounted unit 1 has a U-shaped structure. The outer structure of the skid-mounted unit 1 is made of carbon steel with anti-corrosion structure. The outer protection is made of polyurethane spray insulation and an outer protective panel with powder coating. The interior has a 50mm thick insulation and decorative panel including the top surface. The insulation material is flame retardant. The ground is made of wood with a board thickness of 20mm. The overall external window adopts a one-piece transparent structure. The equipment inlet adopts a roller shutter door. The skid-mounted design greatly simplifies the on-site installation process. The equipment is fully commissioned at the factory. On-site, only pipeline and electrical connections need to be completed, thereby shortening the construction cycle.

[0035] The skid-mounted equipment 1 includes a pretreatment unit, which comprises a feed hopper 2 for filtrate treatment of kitchen waste, a primary screw conveyor 3, a manual sorting platform 4 for removing inorganic materials from the kitchen waste, and a secondary screw conveyor 5. A waste bin tipper with weighing function is installed on one side of the feed hopper 2. The kitchen waste is first poured into the feed hopper 2 through the tipper for initial filtrate treatment. During this process, the tipper automatically weighs the kitchen waste and records the data, importing it into the control system. The primary screw conveyor 3 transports the filtered kitchen waste from the feed hopper 2 to the manual sorting platform 4. Workers on the manual sorting platform 4 remove inorganic materials that were not thoroughly sorted in the initial stage. Inorganic materials include metals, ceramics, etc. The pretreatment unit also includes a crusher. The kitchen waste, after being separated from inorganic materials, is fed into the crusher 6 by the screw press dewatering machine 7 and the secondary screw conveyor 5. The crusher 6 shreds the kitchen waste, and its discharge port is connected to the feed port of the screw press dewatering machine 7. After the crusher 6 shreds the kitchen waste into uniformly sized particles, it is fed into the screw press dewatering machine 7, which dehydrates the shredded kitchen waste. The screw press dewatering machine 7 is equipped with a discharge pipe and a water outlet pipe. The screw press dewatering machine 7 discharges the dehydrated kitchen waste through the discharge pipe and discharges the extruded liquid through the water outlet pipe, thus completing the pretreatment of the kitchen waste. The screw press dewatering machine 7 is a commercially available and mature product, and its working principle will not be described in detail here.

[0036] The structure of crusher 6 is described in detail below, with reference to... Figures 3-6The crusher 6 includes a hollow, vertically connected shell 61, which is bolted to the upper side wall of the screw press dewatering machine 7. The shell 61 is located below the discharge port of the secondary screw conveyor 5. Two symmetrical shredding rollers 62 are horizontally rotatable inside the shell 61, each with several blades fixed on it. The blades on the two shredding rollers 62 are staggered. A drive assembly for driving the two shredding rollers 62 to rotate in opposite directions is located on one side of the shell 61. The drive assembly includes a reducer 63 fixedly mounted on one side of the shell 61. The reducer 63 is a reducer with one input shaft and two output shafts rotating in opposite directions. The reducer 63 can be a SEW-K series dual-output shaft reducer, Nord-SK-9282 dual-shaft reducer, etc., but is not limited to these. The two output shafts of the reducer 63 are respectively connected to… The motor is fixed coaxially to the two shredding rollers 62 via a coupling. The output shaft of the motor is fixed coaxially to the input shaft of the reducer 63 via a coupling. After the motor starts, its output shaft drives the input shaft of the reducer 63 to rotate. The input shaft of the reducer 63 drives the two output shafts to rotate in opposite directions through the transmission component inside the reducer 63. The two output shafts rotating in opposite directions drive the two shredding rollers 62 to rotate synchronously in opposite directions. When the secondary screw conveyor 5 puts the kitchen waste after the inorganic matter has been picked out into the crusher 6, the kitchen waste falls to the middle position between the two shredding rollers 62. At this time, the two rotating shredding rollers 62 cut the kitchen waste with blades, cutting the kitchen waste into small granular pieces. The kitchen waste cut into small granular pieces falls between the two shredding rollers 62 and below the shredding rollers 62.

[0037] Meanwhile, a screen 64 is installed inside the housing 61 below the shredding roller 62. The screen 64 is an approximately W-shaped metal plate with several screen holes on its surface. Two arc-shaped plates are installed on the screen 64, and the axes of the two arc-shaped plates are on the same straight line as the axes of the two shredding rollers 62. The two arc-shaped plates are respectively attached to the rotation trajectory of the two shredding rollers 62. The kitchen waste cut by the shredding rollers 62 will fall onto the screen 64. The screen holes on the screen 64 physically filter the kitchen waste. Kitchen waste smaller than the screen holes will fall into the screw press dewatering machine 7 through the screen holes, while kitchen waste larger than the screen holes will stay on the screen 64. The rotating shredding roller 62 will continue to cut the kitchen waste remaining on the screen 64 until it is cut into a size that can pass through the screen holes. This makes the kitchen waste falling into the screw press dewatering machine 7 into uniformly sized particles, thereby improving the dewatering efficiency of the screw press dewatering machine 7 for kitchen waste.

[0038] During operation, screen 64 easily accumulates waste residue that has not passed through the screen holes, causing screen blockage. This blockage leads to poor material discharge, causing food waste to repeatedly circulate within the housing 61, resulting in reduced production capacity. Simultaneously, the undischarged food waste repeatedly rubs against the blades on the shredding roller 62, shortening the lifespan of the blades. Therefore, workers need to clean screen 64 regularly. Cleaning screen 64 requires removing it from the housing 61 and using methods such as vibration and backflushing to remove waste residue from the screen holes. After long-term use, the screen 64 is prone to deformation due to metal fatigue. Deformation of the screen 64 will cause the screen holes to expand or shrink locally. Some garbage will be discharged without being fully shredded, while garbage will be retained in other areas due to blockage. This will reduce the consistency of the output of the crusher 6. Therefore, when cleaning the screen 64, the workers need to check whether the screen 64 is deformed. In the existing technology, the work of disassembling and assembling the screen 64 and checking whether the screen 64 is deformed cannot be carried out at the same time. The workers can only check the screen 64 after removing it from the inside of the crusher 6, which increases the workload of the workers.

[0039] To solve the above problems, a first slot 611 is provided on one side of the housing 61, and an inspection port is provided on the other side of the housing 61. The inspection port is connected to the interior of the housing 61, and an assembly plate 65 is installed inside the inspection port and fixed to the housing 61 by bolts. The assembly plate 65 blocks the inspection port. A second slot 651 is provided on the assembly plate 65 at a position corresponding to the first slot 611. The two sides of the screen 64 are respectively inserted into the first slot 611 and the second slot 651. The first slot 611 and the second slot 651 are W-shaped to fit the screen 64. The first slot 611 and the second slot 651 provide support for the two sides of the screen 64. The support allows the screen 64 to be stably placed inside the housing 61. At the same time, an end plate 66 is provided on the side of the mounting plate 65 away from the housing 61. One end of the screen 64 is fixed to the end plate 66 by bolts. A handle is fixed on the side of the end plate 66 away from the screen 64. Two baffles 67 are symmetrically rotated and arranged on one side of the housing 61 above the inspection port. When the end plate 66 contacts the mounting plate 65, the baffles 67 are in a vertical state and the lower end of the baffles 67 contacts the side of the end plate 66 away from the mounting plate 65. The baffles 67 and the mounting plate 65 cooperate to prevent the end plate 66 and the screen 64 from moving laterally, thereby fixing the screen 64 inside the housing 61.

[0040] When the worker removes the screen 64 from the inside of the housing 61, they first rotate the two baffles 67 to disengage them from the end plate 66. Then, they pull the end plate 66 away from the housing 61 by holding the handle, causing the end plate 66 to move the screen 64 synchronously. If the screen 64 can be smoothly pulled out of the housing 61 through the second slot 651 during this process, it is determined that the screen 64 has not undergone serious deformation that would affect screening. If the movement of the screen 64 is blocked by the second slot 651, it is determined that the screen 64 has undergone serious deformation. In this case, the worker first uses a wrench or other tools to connect the assembly plate 65 and the housing 61. Unscrew the bolts on body 61, remove assembly plate 65 from inside the inspection port, and remove assembly plate 65, end plate 66, and screen 64 from housing 61 as a whole. Then, use a wrench to unscrew the bolts connecting end plate 66 and screen 64, and screen 64 can be pulled out from inside the second slot 651. Separate end plate 66 and deformed screen 64. Workers discard the deformed screen 64 and install a new screen 64 inside housing 61 to restore the normal use of crusher 6. This allows for the simultaneous disassembly and assembly of screen 64 and inspection of screen 64 for deformation, saving workers' workload.

[0041] After the screw press dewatering machine 7 discharges the kitchen waste extrusion liquid through the outlet pipe, in order to further treat the kitchen waste extrusion liquid and the wastewater filtered by the feed hopper 2, the skid-mounted equipment 1 also includes an oil-water separation unit. The oil-water separation unit is installed in the subsequent processing flow of the screw press dewatering machine 7 to separate the grease, water, and sludge residue from the kitchen waste extrusion liquid, and to collect the separated grease. The structure of the oil-water separation unit is detailed below. The oil-water separation unit includes a diaphragm pump for conveying the kitchen waste extrusion liquid, and is equipped with... In the subsequent processing of the diaphragm pump, the oil-water separator 21 includes a sedimentation tank, a slag collection well at the bottom of the sedimentation tank, an oil collection tank at the top of the sedimentation tank, a spun oil guiding system at the oil outlet of the oil collection tank, and a deep processing module. The deep processing module includes a slag guiding system, an upper separation system, and a lower separation system. When the diaphragm pump delivers the extruded liquid from the kitchen waste into the oil-water separator 21, and the wastewater filtered by the feed hopper 2 is discharged into the oil-water separator 21, the upper separation system and the spun oil guiding system work together to separate the wastewater... The system separates sludge and fine residue from wastewater through a combination of a middle oil separation system, a lower separation system, and a sludge guiding system. These components, along with the spinning oil guiding system, upper separation system, lower separation system, and sludge guiding system, together form a vortex centrifugal sedimentation system. Under the action of this system, wastewater is separated. Due to the different specific gravities of oil, water, and residue in the wastewater, the sludge and residue gradually settle to the sludge collection well at the bottom of the sedimentation tank under centrifugal force, while the grease gradually floats to the oil collection tank. The spinning oil guiding system guides the grease in the oil collection tank to the vicinity of the oil outlet. This spinning oil guiding system ensures that the grease in the oil collection tank... During discharge, there is no blockage. Under the action of the lower separation system and the slag guiding system, the sludge and fine slag in the sewage settle into the slag collection well at the bottom of the cone-shaped sedimentation tank. The slag guiding system is set near the slag discharge port of the slag collection well. The slag guiding system can ensure that the sludge and fine slag in the slag collection well do not block the discharge. The oil-water separation unit also includes an oil storage tank 12 and a sewage tank 13. The spinning oil guiding system transports the grease in the oil collection tank to the inside of the oil storage tank 12 for storage, which facilitates the subsequent recycling of the grease. The sewage separated by the oil-water separator 21 enters the inside of the sewage tank 13 for storage.

[0042] When the screw press dewatering machine 7 discharges the dewatered kitchen waste through the discharge pipe, the skid-mounted equipment 1 also includes an aerobic fermentation and exhaust gas treatment unit for further processing of the dewatered kitchen waste. This unit includes an aerobic fermentation chamber 9 and a UV photolysis machine 14. The kitchen waste dewatered by the screw press dewatering machine 7 is transported to the aerobic fermentation chamber 9 via a vertical elevator 8. The oil-water separation unit transports the separated sludge residue to the aerobic fermentation chamber 9 and mixes it with the kitchen waste for composting. The composting process in the aerobic fermentation chamber 9 is as follows: fermentation bacteria are added to the dewatered and oil-extracted kitchen waste residue and mixed evenly in a certain proportion. After the moisture content reaches the design requirements, the mixture enters the aerobic fermentation chamber 9 to form a pile. The aerobic fermentation chamber 9 adjusts the moisture, oxygen content, and temperature of the pile to ensure thorough aerobic fermentation and decomposition. During the decomposition process, the waste releases... The heat from the fermentation chamber raises the temperature of the sludge to a maximum of 80°C. As the temperature rises, the moisture in the kitchen waste evaporates, and some organic matter decomposes, thus reducing the volume of the waste and achieving waste reduction. The aerobic fermentation chamber 9 controls the temperature of the waste pile between 55°C and 65°C through ventilation, oxygenation, and stirring, achieving the optimal temperature for kitchen waste fermentation. At this temperature, a large number of pathogens and parasites in the waste pile die. Waste gas is generated during the fermentation process and is discharged through the exhaust pipe installed on the aerobic fermentation chamber 9. The exhaust pipe of the aerobic fermentation chamber 9 is connected to the air inlet pipe of the UV photolysis machine 14. The UV photolysis machine 14 is used to deodorize the gas emitted from the aerobic fermentation chamber 9, achieving the purpose of harmless and resource-based treatment. After the aerobic fermentation chamber 9 discharges the fermented kitchen waste residue, workers compost the residue.

[0043] To further treat the wastewater inside the wastewater tank 13, the skid-mounted equipment 1 also includes a wastewater treatment unit. The wastewater treatment unit is used to sequentially perform filtration, biological treatment, and advanced treatment on the water separated by the oil-water separation unit. The processes of filtration, biological treatment, and advanced treatment are described in detail below:

[0044] Filtration treatment: The wastewater treatment unit includes a water treatment tank 10. A feed pump is fixedly installed on the water treatment tank 10. The feed pump first transports the wastewater inside the wastewater tank 13 to the inside of the water treatment tank 10 for pretreatment. The inside of the water treatment tank 10 is equipped with a grid and a mesh plate. The wastewater will pass through the grid and the mesh plate in the water treatment tank 10 to remove large debris such as bones and vegetable leaves, thereby achieving the filtration treatment of wastewater.

[0045] Biological treatment: The wastewater treatment unit includes an MBR membrane tank 11. The output pipe of the water treatment tank 10 is connected to the input pipe of the MBR membrane tank 11. The wastewater filtered by the water treatment tank 10 flows into the interior of the MBR membrane tank 11. The MBR membrane tank 11 combines membrane technology and biological treatment to effectively remove suspended solids and bacteria from the wastewater. The MBR membrane tank 11 is a commercially available and mature product. Its working principle and structure will not be described in detail here.

[0046] In existing technologies, an equalization tank is set up before the sewage enters the MBR membrane tank 11 to regulate the sewage volume and quality. In this solution, a water treatment tank 10 is used instead of an equalization tank to regulate the sewage volume and quality. That is, the water treatment tank 10 can cope with the sewage load that increases and decreases with its sufficient volume, so that the sewage quality and quantity entering the sewage treatment unit are relatively stable, providing stable operating conditions for the subsequent water treatment process. This reduces the sewage treatment process and speeds up the sewage treatment process.

[0047] Advanced Treatment: The wastewater treatment unit includes NF / RO16, which are two types of water treatment equipment based on membrane separation technology. These are mature products available on the market, and their working principles and structures will not be detailed here. The output pipe of the MBR membrane tank 11 is connected to the input pipe of the NF / RO16. When the wastewater filtered by the MBR membrane tank 11 enters the interior of the NF / RO16, the NF / RO16 uses the RO reverse osmosis system + ion exchange adsorption column to remove inorganic salt ions from the wastewater through membrane filtration and resin adsorption. This process is used to remove organic matter that is difficult to biodegrade, thereby treating the wastewater to meet national discharge standards for discharge or recycling.

[0048] The skid-mounted equipment 1 also includes an office 18, an indoor toilet 17, and an electrical control box 19. The office 18 is equipped with soundproof wall panels and a panoramic monitoring screen that displays the processing status of each unit in real time. The indoor toilet 17 has integrated bathroom facilities to meet the needs of staff and fully reflects the humanized design concept. The electrical control box 19 adopts PLC automatic control, which can be switched between manual and automatic modes, automatically cut off faults, and has a safe and reliable system alarm. It can also be remotely viewed and operated via a cloud platform.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
