Description

Technical Field

[0001] This invention belongs to the technical field of waste treatment equipment, specifically a facility for the resource recovery of perishable waste. Background Technology

[0002] Currently, waste disposal is a major problem that plagues people. Among them, the conversion and treatment of perishable waste is a major obstacle to the green development of cities. Perishable waste mainly includes kitchen waste generated by canteens, hotels, restaurants, etc., as well as vegetable and fruit waste, rotten meat, meat scraps and bones, eggshells, and offal from livestock and poultry products generated by farmers' markets and agricultural wholesale markets.

[0003] Methods for treating perishable waste include landfill, incineration, and composting. Composting includes anaerobic fermentation and high-temperature aerobic composting. Anaerobic fermentation utilizes anaerobic microorganisms to convert perishable waste into biogas, biogas slurry, and biogas residue. The biogas can be burned for heating or power generation, achieving resource utilization. In high-temperature aerobic composting, perishable waste is sorted, crushed, and then fed into a treatment device. Under high-temperature and aerobic conditions, the waste is efficiently degraded by microorganisms and further processed into soil conditioners.

[0004] Existing anaerobic fermentation equipment treats perishable waste uniformly without targeted sorting and processing, thus reducing the effectiveness of perishable waste treatment. Furthermore, it lacks weighing capabilities, further reducing waste treatment efficiency, and its poor waste crushing effect also impacts fermentation efficiency. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a facility for the resource recovery and treatment of perishable waste.

[0006] The technical solution of the present invention is: a resource utilization treatment facility for perishable waste, including a waste pretreatment main body with a feeding port at the top, a material guiding opening and closing component disposed in the waste pretreatment main body, and a dry anaerobic digestion treatment component and a wet anaerobic digestion treatment component disposed on the left and right sides of the waste pretreatment main body respectively.

[0007] The main body of the waste pretreatment unit is equipped with a partition plate, which divides the interior of the waste pretreatment unit into a sorting and storage chamber and a material guiding chamber. The sorting and storage chamber is equipped with a material separating vertical plate at the center, and the material dispensing cylinder is equipped with a sorting and dispensing plate at the center of the dispensing cylinder. The left and right ends of the partition plate are respectively equipped with material drop ports.

[0008] The material guiding opening and closing assembly includes a mounting vertical plate located at the center of the material guiding cavity, a material guiding inclined plate symmetrically distributed on the left and right sides of the mounting vertical plate and hinged to the side wall of the mounting vertical plate at its upper end, a hydraulic cylinder located between the bottom end of the material guiding inclined plate and the mounting vertical plate, and material guiding ports located on the left and right sides of the material guiding cavity.

[0009] The dry anaerobic digestion treatment assembly includes a first anaerobic chamber connected to the feed inlet located on the left side via a first crushing installation cylinder, a filter plate located in the first anaerobic chamber and having a collection box at its bottom, a first feed guiding screw located in the first anaerobic chamber and located at the top of the filter plate, a first stacking box connected through the side wall of the first anaerobic chamber, and a first bacterial liquid addition assembly located on the side wall of the first anaerobic chamber. The collection box and the bottom of the first anaerobic chamber are connected to the first collection box via a connecting pipe. A first automatic opening and closing plate is provided at the connection between the first stacking box and the first anaerobic chamber.

[0010] The wet anaerobic digestion treatment assembly includes a second anaerobic chamber whose upper end is connected to the feed inlet located on the right side via a second crushing installation cylinder, a support plate disposed in the second anaerobic chamber, a second feed guide screw disposed in the second anaerobic chamber and located at the upper end of the support plate, a second stacking box connected to the side wall of the second anaerobic chamber and provided with a second automatic opening and closing plate at the connection point, and a second bacterial liquid addition assembly disposed on the side wall of the second anaerobic chamber. The second anaerobic chamber is connected to a first collection tank via a connecting pipe.

[0011] Furthermore, a weighing and transfer assembly is provided in the sorting and storage cavity and on both sides of the material separating vertical plate. The weighing and transfer assembly includes a weighing plate located at the upper end of the separating horizontal plate and equipped with a gravity sensor inside, a scraper frame with its bottom end slidably connected to the weighing plate via a slide rail and having an open structure at both the top and bottom ends, and a driving element located between the scraper frame and the material separating vertical plate.

[0012] Explanation: When perishable waste is placed into the corresponding sorting and storage chamber through the sorting and disposal bins, the weight of the waste is detected by a gravity sensor on the weighing plate. When the preset weight is reached, the waste disposal stops, and the corresponding scraper frame is driven by a drive element to move along the upper part of the weighing plate towards the discharge port. At the same time, the scraper frame moves the waste that falls onto the weighing plate in its own direction of movement. Since the upper and lower ends of the scraper frame are open, when one side of the scraper frame moves to the upper end of the discharge port, the waste falls into the guide chamber through the lower opening of the scraper frame and the discharge port for further processing. By accurately weighing perishable waste, the quantity and quality of waste can be better controlled, thereby optimizing the waste treatment process and improving waste treatment efficiency.

[0013] Furthermore, the side wall of the material separator vertical plate is provided with an installation port, and the driving element includes a vertical mounting rod disposed in the installation port, a sliding mounting ring sleeved on the outside of the vertical mounting rod, two connecting rods for connecting the sliding mounting ring with the scraper frames on the left and right sides of the material separator vertical plate, and a hydraulic rod for driving the sliding mounting ring to slide up and down on the outer wall of the vertical mounting rod.

[0014] Explanation: When the scraper frame is moved left and right by the drive element, the hydraulic rod is opened. The extension of the hydraulic rod causes the sliding mounting ring to slide downward on the vertical mounting rod, thereby causing the connecting rod to move downward synchronously. At this time, the connecting rod will push the scraper frame connected to it to move closer to the discharge port. When it is necessary to move the scraper frame back to its original position, the compression of the hydraulic rod causes the sliding mounting ring to slide upward on the vertical mounting rod. At this time, the connecting rod will pull the scraper frame connected to it to move away from the discharge port. Through the above structure, the synchronous movement of each scraper frame is completed, and the synchronous weighing, transfer and processing of different types of waste are achieved, which greatly improves the overall working efficiency of the device.

[0015] Furthermore, the first anaerobic chamber is provided with multiple parallel filter plates from top to bottom, each filter plate is provided with a first guide screw, and each filter plate is provided with a liquid collection box at its bottom. The connection between the first stacking box and the first anaerobic chamber and corresponding to each filter plate is provided with a first automatic opening and closing plate. The second anaerobic chamber is provided with multiple parallel support plates from top to bottom, each support plate is provided with a second guide screw, and the connection between the second stacking box and the second anaerobic chamber and corresponding to each support plate is provided with a second automatic opening and closing plate.

[0016] Explanation: The purpose of setting up several filter plates distributed from top to bottom is to continuously process several batches of perishable waste of the same weight that are weighed sequentially, shortening the interval between processing two adjacent batches of perishable waste of the same weight, and maintaining the continuity of processing different batches of perishable waste. After the kitchen waste is crushed by the first crushing cylinder, it falls to the top of each filter plate for solid-liquid separation. The separated liquid flows to the corresponding collection box. At this time, the first guide screw is driven by external equipment to rotate clockwise and counterclockwise alternately, and anaerobic bacterial liquid is added to the first anaerobic chamber to stir the kitchen waste and carry out dry anaerobic fermentation. After fermentation is completed, each filter plate is opened. The first automatic opening and closing plate, through the continuous counterclockwise rotation of the first guiding screw, pushes the fermentation products on the upper part of each filter plate out and drops them into the first material bin for final recycling. The second anaerobic chamber is used for the treatment of perishable waste such as fruits and vegetables. The treatment process is the same as the above process, except that the supporting plate does not have a solid-liquid separation effect. By classifying and treating perishable waste such as kitchen waste and fruits and vegetables, we can promote waste reduction and classification, reduce the amount of waste to be treated, and at the same time promote public awareness and action on waste classification and resource recycling. In addition, through different fermentation methods, it is converted into fertilizer or energy, realizing the recycling of resources.

[0017] Furthermore, the first bacterial solution addition component includes a bacterial solution spraying plate disposed from top to bottom in the first anaerobic chamber and located at the upper end of each of the filter media plates, a connecting main pipe connected to each of the bacterial solution spraying plates via connecting branch pipes, a bacterial solution holding tank disposed on the side wall of the first anaerobic chamber and connected to the connecting main pipe, and a liquid pump disposed at the connection between the bacterial solution holding tank and the connecting main pipe.

[0018] Instructions: When it is necessary to add anaerobic bacterial solution to the first anaerobic chamber, start the pump. The pump will draw the anaerobic bacterial solution from the container into each spray plate via the main pipe and branch pipes. The solution will then be sprayed onto the perishable waste on the upper part of the corresponding filter plate, thus carrying out dry anaerobic fermentation. This allows the anaerobic bacteria to better contact the waste and improves fermentation efficiency.

[0019] Furthermore, the structure of the second bacterial solution addition component is the same as that of the first bacterial solution addition component, and the bacterial solution spraying plates corresponding to the second bacterial solution addition component are distributed from top to bottom on the inner wall of the second anaerobic chamber.

[0020] Note: When it is necessary to add anaerobic bacterial solution to the second anaerobic chamber, the working process of the second bacterial solution addition component is the same as that of the first bacterial solution addition component. The purpose is to spray the bacterial solution onto various parts of the perishable waste on the upper part of the corresponding filter plate, so as to carry out wet anaerobic fermentation treatment, so that the anaerobic bacteria can better contact the waste and improve the fermentation efficiency.

[0021] Furthermore, the upper ends of the first and second stockpiles are respectively connected to biogas purifiers via connecting pipes, and the bottom ends of both the first and second stockpiles are connected to anaerobic sludge processors, which are connected to biogas residue processors and biogas slurry processors.

[0022] Explanation: The biogas produced by anaerobic fermentation in the first and second anaerobic chambers is collected, purified, and reused through a biogas purifier. The fermented sludge is dewatered and reused through an anaerobic sludge processor. The biogas slurry produced by dewatering is purified and discharged through a biogas slurry processor. The biogas residue produced is purified and discharged through a biogas residue processor. The above process can realize the full utilization and purification of waste, promote sustainable development, achieve the dual benefits of resource recycling and environmental protection, and at the same time promote energy transformation and green economic development.

[0023] Furthermore, the first crushing installation cylinder is equipped with a waste crushing component, which includes a first crushing screen plate disposed in the first crushing installation cylinder, a second crushing screen plate disposed in the first crushing installation cylinder and located at the lower end of the first crushing screen plate, a crushing rod disposed on the first crushing screen plate and driven by a motor, and a plurality of crushing rollers disposed in the first crushing installation cylinder and located at the upper end of the second crushing screen plate. The mesh size of the second crushing screen plate is greater than that of the first crushing screen plate, and the structure inside the second crushing installation cylinder is the same as that of the first crushing installation cylinder.

[0024] Explanation: When crushing kitchen waste through the first crushing cylinder, the crushing rod driven by the motor rotates, and the kitchen waste is initially crushed. After crushing, the waste fragments that meet the usage requirements fall through the first crushing screen plate between two adjacent crushing rollers, where they undergo secondary crushing. The crushed waste fragments then fall through the bottom of the first crushing cylinder into the first anaerobic chamber. By using a combination of crushing and crushing to process kitchen waste, it can be broken down into smaller particles, thereby increasing its surface area and improving fermentation efficiency.

[0025] Furthermore, a loosening assembly is provided inside the first crushing installation cylinder and at the upper end of the second crushing screen plate. The loosening assembly includes a vertical installation rod located inside the first crushing installation cylinder and driven by a motor, a rotating installation plate rotatably connected to the outer wall of the vertical installation rod via a connecting sleeve, an installation notch located at the bottom end of the rotating installation plate, and a loosening plate connected to the side wall of the installation notch via an electric telescopic rod and having multiple loosening teeth at its bottom end.

[0026] Explanation: After the waste is crushed by the rollers, it is easy for the waste to stick together. The loosening component can increase the fluffiness of the crushed waste. When using the loosening component, the vertical mounting rod is driven by a motor to rotate, so that the rotating mounting plate connected to the connecting sleeve rotates to the top of the second crushing screen plate. At this time, the electric telescopic rod is activated. Through the repeated compression and extension of the electric telescopic rod, the loosening teeth at the bottom of the loosening plate repeatedly loosen the waste on the top of the crushed waste. This increases the fluffiness of the crushed waste, increases the surface area of ​​the waste, and makes the distribution of bacteria more uniform. It avoids the situation of too many or too few bacteria in some areas, thereby improving the fermentation effect.

[0027] This invention also discloses a method for the resource recovery and treatment of perishable waste, based on the aforementioned perishable waste resource recovery and treatment facility, comprising the following steps:

[0028] S1. Kitchen waste is placed into the left side of the sorting and storage chamber through the left side of the sorting and disposal bin, and then falls into the left side of the guide chamber through the discharge port. At this time, the hydraulic cylinder on the left side of the guide chamber is activated. The extension action of the hydraulic cylinder drives the corresponding guide inclined plate to rise, guiding the falling kitchen waste through the guide port into the first crushing and installation cylinder for crushing and forming waste fragments. Then, the waste fragments fall into the filter plate in the first anaerobic chamber through the first crushing and installation cylinder, and solid-liquid separation is performed through the filter plate. After separation, the liquid flows into the collection box. At this time, the first guide screw is driven by external equipment to rotate clockwise and counterclockwise alternately. Anaerobic bacterial liquid is added into the first anaerobic chamber through the first bacterial liquid addition component, stirring the kitchen waste and carrying out dry anaerobic fermentation. After fermentation, the first automatic opening and closing plate is opened. Through the continuous counterclockwise rotation of the first guide screw, the fermentation product at the top of the filter plate is pushed out and falls into the first stacking box for recycling.

[0029] S2. Fruit and vegetable waste is placed into the right side of the sorting and storage chamber through the right side of the sorting and disposal bin, and then falls into the right side of the guide chamber through the discharge port. At this time, the hydraulic cylinder on the right side of the guide chamber is activated. The extension action of the hydraulic cylinder drives the corresponding guide inclined plate to lift upward, guiding the fallen fruit and vegetable waste through the guide port into the second crushing and installation cylinder for crushing and processing, forming waste fragments. Then, the waste fragments fall into the support plate in the second anaerobic chamber through the second crushing and installation cylinder. At this time, the liquid after solid-liquid separation of kitchen waste in the first liquid collection tank is pumped onto the support plate. The second guide screw is driven by external equipment to rotate clockwise and counterclockwise alternately. Anaerobic bacteria liquid is added into the second anaerobic chamber through the second bacterial liquid addition component to carry out wet anaerobic fermentation of fruit and vegetable waste. After fermentation, the second automatic opening and closing plate is opened. Through the continuous clockwise rotation of the second guide screw, the fermentation products at the top of the support plate are pushed out and fall into the second stacking bin for final recycling.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] The perishable waste resource recovery facility of this invention allows for the separate and targeted treatment of perishable kitchen waste and fruit and vegetable waste. Kitchen waste undergoes dry anaerobic digestion, while fruit and vegetable waste undergoes wet anaerobic digestion. This ensures thorough decomposition of organic matter and reduces the emission of harmful gases. During wet anaerobic digestion, the filtrate from dry anaerobic digestion is used as leachate, enriching the organic matter and nutrient content of the wet anaerobic digestion process. Furthermore, it eliminates the need for separate filtrate treatment, thus contributing to energy conservation and emission reduction. When perishable waste is placed into the corresponding sorting compartments via the sorting bins, a gravity sensor on a weighing plate detects the weight of the waste. This allows for better control over the quantity and quality of waste, thereby optimizing the waste treatment process and improving efficiency. Several filter plates and support plates distributed from top to bottom can continuously process batches of perishable waste of the same weight, shortening the interval between processing adjacent batches and maintaining continuity in the processing of different batches. The combination of crushing and grinding in the treatment of kitchen waste breaks it down into smaller particles, increasing surface area and improving fermentation efficiency. Simultaneously, the loosening component increases the fluffiness of the crushed waste, further increasing surface area and resulting in a more even distribution of microorganisms, preventing areas with excessive or insufficient microorganisms and thus improving fermentation effectiveness.

The collection box 320 and the bottom end of the first anaerobic chamber 31 are connected to a first collection tank 35 via a connecting pipe. A first automatic opening and closing plate 340 is provided at the connection between the first stacking box 34 and the first anaerobic chamber 31.

[0045] The wet anaerobic digestion treatment component 4 includes a second anaerobic chamber 41, which is connected to the feed inlet 23 located on the right side through a second crushing installation cylinder 40; a support plate 42 located in the second anaerobic chamber 41; a second feed guide screw 43 located in the second anaerobic chamber 41 and located above the support plate 42; a second stacking box 44 connected to the side wall of the second anaerobic chamber 41 and provided with a second automatic opening and closing plate 440 at the connection point; and a second bacterial liquid addition component 45 located on the side wall of the second anaerobic chamber 41. The second anaerobic chamber 41 is connected to the first collection tank 35 through a connecting pipe.

[0046] like Figure 5 As shown, the first bacterial solution addition component 36 includes a bacterial solution spraying plate 360 ​​disposed from top to bottom in the first anaerobic chamber 31 and located at the top of each filter plate 32, a connecting main pipe 361 connected to each bacterial solution spraying plate 360 ​​through a connecting branch pipe 3610, a bacterial solution holding tank 362 disposed on the side wall of the first anaerobic chamber 31 and connected to the connecting main pipe 361, and a liquid pump 363 disposed at the connection between the bacterial solution holding tank 362 and the connecting main pipe 361;

[0049] Example 2

[0050] This embodiment discloses a method for the resource recovery and treatment of perishable waste, based on a perishable waste resource recovery and treatment facility according to Embodiment 1, including the following steps:

[0051] S1. Kitchen waste is fed into the left side of the sorting and storage chamber 12 through the left side of the sorting and disposal bin 100, and falls into the left side of the guide chamber 13 through the discharge port 110. At this time, the hydraulic cylinder 22 on the left side of the guide chamber 13 is activated. Through the extension action of the hydraulic cylinder 22, the corresponding guide inclined plate 21 is pushed upward, guiding the falling kitchen waste through the guide port 23 into the first crushing and installation cylinder 30 for crushing and processing, forming waste fragments. Then, the waste fragments fall into the filter plate 32 in the first anaerobic chamber 31 through the first crushing and installation cylinder 30. Solid-liquid separation is achieved through the filter plate 32. After separation, the liquid flows to the collection box 320. At this time, the first guide screw 33 is driven by external equipment to rotate clockwise and counterclockwise alternately. Anaerobic bacterial liquid is added to the first anaerobic chamber 31 through the first bacterial liquid addition component 36. The kitchen waste is stirred and dry anaerobic fermentation is carried out. After fermentation, the first automatic opening and closing plate 340 is opened. The fermentation product at the top of the filter plate 32 is pushed out and falls into the first pile box 34 through the continuous counterclockwise rotation of the first guide screw 33. Finally, it is recycled.

[0052] S2. Fruit and vegetable waste is placed into the right side of the sorting and storage chamber 12 through the sorting and disposal bin 100, and falls into the right side of the guide chamber 13 through the discharge port 110. At this time, the hydraulic cylinder 22 on the right side of the guide chamber 13 is activated. Through the extension action of the hydraulic cylinder 22, the corresponding guide inclined plate 21 is pushed upward, guiding the fallen fruit and vegetable waste through the guide port 23 into the second crushing and installation cylinder 40 for crushing and processing, forming waste fragments. Then, the waste fragments fall into the support plate 42 in the second anaerobic chamber 41 through the second crushing and installation cylinder 40. At this point, the liquid from the solid-liquid separation of kitchen waste in the first collection tank 35 is pumped onto the support plate 42. The second guide screw 43 is driven by external equipment to rotate clockwise and counterclockwise alternately. Anaerobic bacterial liquid is added into the second anaerobic chamber 41 through the second bacterial liquid addition component 45 to carry out wet anaerobic fermentation of fruit and vegetable waste. After fermentation, the second automatic opening and closing plate 440 is opened. Through the continuous clockwise rotation of the second guide screw 43, the fermentation product at the top of the support plate 42 is pushed out and falls into the second stacking box 44 for final recycling.

[0053] S3. When it is necessary to add anaerobic bacterial liquid to the first anaerobic chamber 31, start the pump 363. The anaerobic bacterial liquid in the bacterial liquid holding tank 362 is pumped through the main pipe 361 and each connecting branch pipe 3610 to each bacterial liquid spraying plate 360. The bacterial liquid is then sprayed on the perishable waste on the upper part of the corresponding filter plate 32 through the bacterial liquid spraying plate 360, thereby carrying out dry anaerobic fermentation treatment.

[0054] S4. When it is necessary to add anaerobic bacterial liquid to the second anaerobic chamber 41, the working process of the second bacterial liquid adding component 45 is the same as that of the first bacterial liquid adding component 36. The purpose is to spray the bacterial liquid onto the perishable waste on the upper part of the corresponding filter plate 32, so as to carry out wet anaerobic fermentation treatment.

[0055] Example 3

[0056] The difference between this embodiment and Embodiment 1 is that:

[0057] like Figure 3 , 4 As shown, weighing and transfer components 14 are provided in the classification storage cavity 12 and on both sides of the material separating vertical plate 120. The weighing and transfer components 14 include a weighing plate 141 located at the upper end of the separating horizontal plate 11 and equipped with a gravity sensor 140, a scraper frame 142 with its bottom end slidably connected to the weighing plate 141 via a slide rail and having open structures at both the top and bottom ends, and a driving element located between the scraper frame 142 and the material separating vertical plate 120.

[0058] The side wall of the material separating vertical plate 120 is provided with an installation port 121, and the driving element includes a vertical mounting rod 122 provided in the installation port 121, a sliding mounting ring 123 sleeved on the outside of the vertical mounting rod 122, two connecting rods 124 for connecting the sliding mounting ring 123 and the scraper frames 142 on the left and right sides of the material separating vertical plate 120, and a hydraulic rod 125 for driving the sliding mounting ring 123 to slide up and down on the outer wall of the vertical mounting rod 122;

[0059] The gravity sensor 140 and the hydraulic rod 125 both use existing technologies.

[0060] Example 4

[0061] The difference between this embodiment and Embodiment 2 is that:

[0062] When perishable waste is placed into the corresponding sorting storage chamber 12 through the sorting and disposal cylinder 100, the weight of the waste is detected by the gravity sensor 140 on the weighing plate 141. When the preset weight is reached, the waste is stopped from being placed. The corresponding scraper frame 142 is driven by the drive element to move along the upper end of the weighing plate 141 towards the side closer to the discharge port 110. At the same time, the scraper frame 142 moves the waste that falls onto the weighing plate 141 along its own moving direction. Since the upper and lower ends of the scraper frame 142 are open structures, when one side of the scraper frame 142 moves to the upper end of the discharge port 110, the waste falls into the guide chamber 13 through the opening structure at the lower end of the scraper frame 142 and the discharge port 110 for further processing.

[0063] When the scraper frame 142 is moved left and right by the drive element, the hydraulic rod 125 is opened. The extension of the hydraulic rod 125 causes the sliding mounting ring 123 to slide downward on the vertical mounting rod 122, thereby causing the connecting rod 124 to move downward synchronously. At this time, the connecting rod 124 will push the scraper frame 142 connected to it to move closer to the discharge port 110. When it is necessary to move the scraper frame 142 back to its original position, the compression of the hydraulic rod 125 causes the sliding mounting ring 123 to slide upward on the vertical mounting rod 122. At this time, the connecting rod 124 will pull the scraper frame 142 connected to it to move away from the discharge port 110.

[0064] Example 5

[0065] The difference between this embodiment and embodiment 3 is that:

[0066] like Figure 1 As shown, the first anaerobic chamber 31 has two parallel filter plates 32 arranged from top to bottom. Each filter plate 32 is equipped with a first guide screw rod 33. Each filter plate 32 has a liquid collection box 320 at its bottom. The connection between the first stacking box 34 and the first anaerobic chamber 31, and corresponding to each filter plate 32, is equipped with a first automatic opening and closing plate 340. The second anaerobic chamber 41 has multiple parallel support plates 42 arranged from top to bottom. Each support plate 42 is equipped with a second guide screw rod 43. The connection between the second stacking box 44 and the second anaerobic chamber 41, and corresponding to each support plate 42, is equipped with a second automatic opening and closing plate 440.

[0067] Example 6

[0068] The difference between this embodiment and embodiment 4 is that:

[0069] After the kitchen waste is crushed by the first crushing cylinder 30, it falls onto the upper part of each filter plate 32 for solid-liquid separation. The separated liquid flows to the corresponding collection box 320. At this time, the first guide screw 33 is driven by external equipment to rotate clockwise and counterclockwise alternately, and anaerobic bacterial liquid is added into the first anaerobic chamber 31 to stir the kitchen waste and carry out dry anaerobic fermentation. After the fermentation is completed, the first automatic opening and closing plate 340 at each filter plate 32 is opened. Through the continuous counterclockwise rotation of the first guide screw 33, the fermentation products at the upper part of each filter plate 32 are pushed out and fall into the first stacking box 34 for recycling. The second anaerobic chamber 41 is used for the treatment of perishable waste such as fruits and vegetables. The treatment process is the same as the above process, except that the bearing plate 42 does not have the solid-liquid separation effect.

[0070] Example 7

[0071] The difference between this embodiment and embodiment 5 is that:

[0072] like Figure 1 As shown, the upper ends of the first material bin 34 and the second material bin 44 are respectively connected to the biogas purifier 15 through connecting pipes, and the bottom ends of the first material bin 34 and the second material bin 44 are both connected to the anaerobic sludge processor 16. The anaerobic sludge processor 16 is connected to the biogas residue processor 160 and the biogas slurry processor 161.

[0073] like Figure 6 As shown, a waste crushing assembly 5 is provided inside the first crushing installation cylinder 30. The waste crushing assembly 5 includes a first crushing screen plate 50 disposed inside the first crushing installation cylinder 30, a second crushing screen plate 51 disposed inside the first crushing installation cylinder 30 and located at the lower end of the first crushing screen plate 50, a crushing rod 52 disposed on the first crushing screen plate 50 and driven by a motor, and three crushing rollers 53 disposed inside the first crushing installation cylinder 30 and located at the upper end of the second crushing screen plate 51. The mesh size of the second crushing screen plate 51 is greater than that of the first crushing screen plate 50. The structure inside the second crushing installation cylinder 40 is the same as that of the first crushing installation cylinder 30.

[0074] A loosening assembly 6 is provided inside the first crushing installation cylinder 30 and at the upper end of the second crushing screen plate 51. The loosening assembly 6 includes a vertical installation rod 60 located inside the first crushing installation cylinder 30 and driven by a motor, a rotating installation plate 61 rotatably connected to the outer wall of the vertical installation rod 60 through a connecting sleeve 610, an installation notch 62 located at the bottom end of the rotating installation plate 61, and a loosening plate 63 connected to the side wall of the installation notch 62 through an electric telescopic rod 630 and having 10 loosening teeth 631 at its bottom end.

[0075] Among them, the biogas purifier 15, the anaerobic sludge processor 16, the biogas residue processor 160, the biogas liquid processor 161, the rolling roller 53, and the electric telescopic rod 630 adopt existing technologies.

[0076] Example 8

[0077] The difference between this embodiment and embodiment 6 is that:

[0078] The biogas produced by anaerobic fermentation in the first anaerobic chamber 31 and the second anaerobic chamber 41 is collected, purified and reused by the biogas purifier 15. The fermented sludge is dewatered and reused by the anaerobic sludge processor 16. The biogas slurry produced by the dewatering process is purified and discharged by the biogas slurry processor 161. The biogas sludge produced by the biogas residue processor 160 is purified and discharged.

[0079] When kitchen waste is crushed by the first crushing cylinder 30, the crushing rod 52 driven by the motor rotates and performs the initial crushing treatment on the kitchen waste. After crushing, the waste fragments that meet the usage requirements fall between two adjacent crushing screen plates 50 and the crushing rollers 53. The crushing rollers 53 then perform a secondary crushing treatment on the waste fragments. The crushed waste fragments fall into the first anaerobic chamber 31 from the bottom of the first crushing cylinder 30.

[0080] After the garbage is crushed by the crushing roller 53, it is easy for it to stick together. The loosening component 6 can increase the looseness of the crushed garbage. When the loosening component 6 is in use, the vertical mounting rod 60 is driven by the motor to rotate, so that the rotating mounting plate 61 connected to the connecting sleeve 610 rotates to the top of the second crushing screen plate 51. At this time, the electric telescopic rod 630 is activated. Through the repeated compression and extension of the electric telescopic rod 630, the loosening teeth 631 at the bottom of the loosening plate 63 repeatedly loosen the crushed garbage.
