Description

Technical Field

[0001] The utility model relates to a restaurant kitchen waste treatment system, specifically a restaurant kitchen waste collection and treatment system based on a negative pressure pipeline. The system is suitable for places such as the catering industry, large canteens, and food processing plants that generate a large amount of restaurant kitchen waste, and is intended to collect and treat restaurant kitchen waste efficiently and in an environmentally friendly manner. Background Art

[0002] Food waste treatment technology refers to the technology for effectively treating and recycling organic waste generated by the catering industry, household kitchens and food processing plants. Common treatment methods include physical separation, chemical treatment and biological treatment, etc. The purpose is to separate and recycle the usable resources (such as grease, organic matter, etc.) in food waste while reducing pollution to the environment.

[0003] In the process of food waste treatment, oil-water separation is one of the key steps. The oil-water separation effect directly affects the oil recovery rate and the economic benefits of the treatment system. Efficient oil-water separation technology can not only improve the purity and recovery rate of oil, increase economic benefits, but also reduce wastewater treatment costs and reduce environmental pollution. Therefore, the optimization of oil-water separation effect is crucial to the overall benefits and environmental benefits of the food waste treatment system.

[0004] Utility model patent CN209849527U discloses a food waste collection and treatment system based on a biodegradation machine, which includes a garbage delivery box, a garbage conveying pipeline, a material-gas separator, a negative pressure power device and a biodegradation machine. The food waste enters the material-gas separator through the conveying pipeline under negative pressure power to separate the gas from the food waste, and then enters the solid-liquid separator to separate the solid waste from the liquid waste. The solid waste is transported to the biodegradation machine for treatment, and the liquid waste enters the oil-water separator for oil-water separation.

[0005] Although the existing kitchen waste treatment system has achieved resource utilization to a certain extent, there are still some problems in the oil-water separation effect.

[0006] First, much of the grease in kitchen waste is fused in solids, and it is difficult to effectively separate this part of the grease with the existing technology. For example, in patent document CN209849527U, although the solid-liquid separator and the oil-water separator can separate grease and water, due to the close combination of grease and solid waste, many greases cannot be completely separated, resulting in low purity of the grease finally separated. Since the grease in solid waste cannot be effectively separated, the grease will remain in the solid waste, increasing its oil content.

[0007] Secondly, solid waste with high oil content will cause a series of problems during subsequent treatment, such as composting, incineration or biodegradation. For example, in the composting process, excessive oil will affect the activity of microorganisms, prolong the composting time and reduce the quality of compost; in the incineration process, solid waste with high oil content will lead to incomplete combustion, increase harmful gas emissions and pollute the environment; in the biodegradation process, oil will inhibit the degradation activity of microorganisms and reduce the degradation efficiency. Therefore, the existing system has a poor effect on the separation of oil and fat in solid waste, which not only affects the efficiency of resource recovery, but also increases the difficulty and cost of subsequent treatment.

[0008] It can be seen that the existing technology still needs to be improved and advanced. Utility Model Content

[0009] In view of the above-mentioned deficiencies in the prior art, the purpose of the present utility model is to provide a negative pressure pipeline collection and treatment system for kitchen waste, aiming to solve the problem that the existing system has poor grease separation effect in solid waste, which not only affects the resource recovery efficiency, but also increases the difficulty and cost of subsequent processing.

[0010] The technical solution of the utility model is as follows:

[0011] A negative pressure pipeline collection and treatment system for restaurant kitchen waste, the system comprising: a garbage delivery box, a garbage conveying pipeline, a negative pressure power device, a crushing pulping machine and a three-phase oil-water separator; the crushing pulping machine is connected to the garbage delivery box and is used to crush and pulp the restaurant kitchen waste; the three-phase oil-water separator is connected to the crushing pulping machine and is used to separate grease from the prepared pulp.

[0012] The effect of the above scheme is that: the utility model uses a crushing pulping machine to crush the kitchen waste, so that the grease in the solid waste can be released, and then mixed with water to form a slurry, so as to be easier to separate and process later; the design can improve the separation efficiency of grease, ensure that the grease in the solid waste can be fully separated, reduce the grease residue rate, and improve the purity of the separated grease. In addition, the utility model also introduces a three-phase oil-water separator, which uses its high-speed centrifugal effect to more effectively separate the grease from the water in the liquid waste; through the application of the three-phase oil-water separator, the grease in the solid waste can be completely separated, thereby reducing its residue rate, improving the purity of the grease, and reducing the difficulty and cost of subsequent processing. Therefore, the utility model solves the problem that the existing system has a poor grease separation effect in solid waste, which not only affects the resource recovery efficiency, but also increases the difficulty and cost of subsequent processing.

[0013] In a further preferred embodiment, the crushing pulping machine includes: a garbage receiving box, a first motor, a first screw conveying mechanism, a crushing mechanism, a filtering mechanism and a second screw conveying mechanism. The garbage receiving box is connected to the garbage conveying pipe, the first motor is used to drive the first screw conveying mechanism to rotate, the first screw conveying mechanism is connected to the crushing mechanism, the crushing mechanism is arranged downstream of the first screw conveying mechanism, and the filtering mechanism is arranged between the crushing mechanism and the second screw conveying mechanism.

[0014] The effect of the above scheme is that the utility model can effectively receive and transport food waste to subsequent processing equipment through the connection between the garbage receiving box and the garbage conveying pipeline. The operation of the first motor drives the rotation of the first spiral conveying mechanism to transport the food waste to the crushing mechanism along the pipeline. The crushing mechanism is located downstream of the first spiral conveying mechanism, and uses a specially designed mechanism to crush the food waste to make it into a slurry. Subsequently, the crushed food waste slurry enters the filtering mechanism, which is located between the crushing mechanism and the second spiral conveying mechanism. The filtering mechanism can further remove solid particles, impurities and residual grease in the slurry through a specific filtering method, thereby improving the purity of the slurry. Finally, the filtered food waste slurry is transported to the next processing link through the second spiral conveying mechanism.

[0015] Through the design of the crushing mechanism, the kitchen waste can be fully crushed and made into a slurry, which is conducive to releasing the grease fused in the solid waste and improving the separation efficiency of the grease. The setting of the filtering mechanism can further filter the slurry, remove the solid particles, impurities and residual grease therein, improve the separation purity of the grease, and reduce the residual grease rate. The design of the first spiral conveying mechanism and the second spiral conveying mechanism enables the entire processing process to be carried out continuously, improves the processing efficiency, and reduces energy consumption and costs. The reasonable connection and layout of each component constitute a complete processing system, which can effectively complete the entire processing process from kitchen waste collection to grease separation, and improve the stability and reliability of the system.

[0016] In a further preferred embodiment, the crushing mechanism includes: a garbage storage box, a crushing gear, a linkage shaft and a crushing rod. The garbage storage box is arranged on the outer edge of the first spiral conveying mechanism and is connected to the garbage receiving box. The crushing gear is arranged in the garbage storage box and shares a rotating shaft with the first spiral conveying mechanism; the linkage shaft is connected to the crushing gear and rotates with the crushing gear; the crushing rod is sleeved on the outer edge of the linkage shaft.

[0017] The effect of the above scheme is that: by setting up the garbage temporary storage box, the food waste delivered from the first spiral conveying mechanism can be temporarily stored, ensuring the continuous supply of garbage and preventing incomplete crushing caused by uneven conveying. The design of the crushing gear and the first spiral conveying mechanism sharing the rotating shaft, through the linkage shaft, the crushing gear and the crushing rod are linked to ensure the synchronous progress of the crushing process, which can effectively improve the crushing efficiency. The crushing rod is sleeved on the outer edge of the linkage shaft. When the crushing gear rotates, the crushing rod rotates accordingly, and the garbage is fully crushed and squeezed, especially the grease fused in the solid garbage can be effectively released, further improving the effect of subsequent grease separation. In addition, the combination of the crushing gear and the crushing rod can form an efficient crushing force in the garbage temporary storage box, ensuring that all food waste is fully crushed into fine particles, which is conducive to improving the uniformity and purity of the slurry, thereby further improving the separation efficiency and grease purity in the subsequent solid-liquid separation and oil-water separation process. Therefore, the scheme improves the release and separation effect of grease in food waste by optimizing the structural design of the crushing mechanism, effectively improves the resource recovery efficiency, and reduces the difficulty and cost of subsequent treatment.

[0018] In a further preferred embodiment, the linkage shafts are provided in plurality, and the plurality of linkage shafts are arranged in a circular array on the outer edge of the transmission shaft of the first screw conveying mechanism; the crushing rods are provided in plurality, and the plurality of crushing rods are sleeved on the same linkage shaft to form a crushing coaxial rod group.

[0019] The effect of the above scheme is that by setting up multiple linkage shafts and arranging them in a circular array on the outer edge of the transmission shaft of the first spiral conveying mechanism, the working area and crushing efficiency of the crushing mechanism can be effectively increased. The setting of multiple linkage shafts can make the crushing mechanism evenly stressed during operation, avoiding damage or low working efficiency caused by uneven stress on a single linkage shaft. In addition, the setting of the crushing rod is also very critical. By setting up multiple crushing rods on the same linkage shaft to form a crushing coaxial rod group, the crushing force of the crushing mechanism can be made more uniform and powerful, which helps to fully crush the solid waste and improve the crushing efficiency. Such a design can not only effectively release the grease fused in the solid waste and improve the subsequent separation effect, but also ensure the stability and reliability of the entire crushing process, thereby further improving the working efficiency of the system and the thoroughness of grease separation. Therefore, the scheme effectively improves the working efficiency and stability of the crushing mechanism by optimizing the setting of the linkage shaft and the crushing rod, thereby improving the overall performance of the system and the grease separation effect.

[0020] In a further preferred embodiment, a plurality of the crushing gears are provided, and a crushing circumferential rod group is provided between adjacent crushing gears, and the crushing circumferential rod group is composed of crushing rods on different crushing coaxial rod groups located on the same vertical plane.

[0021] The effect of the above scheme is that by setting a plurality of crushing gears and setting a crushing circumferential rod group between adjacent crushing gears, the working area and crushing efficiency of the crushing mechanism can be effectively increased. The design of setting a crushing circumferential rod group between adjacent crushing gears enables the crushing mechanism to crush solid waste more evenly during operation, avoiding the problem of incomplete local crushing caused by uneven crushing. The crushing circumferential rod group is composed of crushing rods on different crushing coaxial rod groups on the same vertical plane. This layout can make the range of action of the crushing rod more comprehensive and improve the crushing efficiency and crushing uniformity of solid waste. This design scheme can not only more effectively release the grease fused in the solid waste and improve the subsequent separation effect, but also ensure the stability and reliability of the entire crushing process, thereby further improving the working efficiency of the system and the thoroughness of grease separation. Therefore, by optimizing the setting of the crushing gears and the layout of the crushing circumferential rod group, this scheme effectively improves the working efficiency and crushing uniformity of the crushing mechanism, thereby improving the overall performance of the system and the grease separation effect.

[0022] In a further preferred embodiment, two circumferential crushing rod groups are arranged between adjacent crushing gears.

[0023] The effect of the above scheme is that by setting two crushing circumferential rod groups, the working efficiency and crushing uniformity of the crushing mechanism can be further increased. The design of setting two crushing circumferential rod groups between adjacent crushing gears can make the crushing mechanism more efficient in crushing solid waste during operation. Compared with the setting of a single crushing circumferential rod group, the two crushing circumferential rod groups can provide more crushing rods, thereby increasing the working area and crushing efficiency of the crushing mechanism. In addition, the mutual cooperation between the two crushing circumferential rod groups can make the crushing process more continuous and uniform, avoiding the problem of incomplete local crushing caused by uneven crushing. Such a design scheme can more effectively release the grease fused in the solid waste, improve the subsequent separation effect, ensure the stability and reliability of the entire crushing process, and further improve the working efficiency of the system and the thoroughness of grease separation. Therefore, by increasing the number of crushing circumferential rod groups, the scheme effectively improves the working efficiency and crushing uniformity of the crushing mechanism, thereby improving the overall performance and grease separation effect of the system.

[0024] In a further preferred embodiment, the filtering mechanism comprises: a filtering box and a filtering plate; the filtering plate is arc-shaped, fitted to the inner wall of the filtering box, and has filtering holes arranged in an array.

[0025] The effect of the above scheme is that by designing an arc-shaped filter plate, fitting it to the inner wall of the filter box, and arranging filter holes in an array thereon, a more efficient filtering effect is achieved. First, the filter plate is in an arc shape, which can make the liquid produce a larger flow area when flowing through the filter plate, thereby increasing the contact area between the filter plate and the liquid, which is beneficial to filtering out impurities in the liquid. Secondly, the array arrangement of the filter holes allows the liquid to pass through the filter plate evenly, avoiding the problem of uneven filtering effect caused by excessive liquid flow in some areas. Therefore, this scheme improves the filtering efficiency and filtering quality of the filtering mechanism by optimizing the shape of the filter plate and the arrangement of the filter holes, ensures the purity and stability of the liquid during the system processing process, and further improves the overall performance and reliability of the system.

[0026] In a further preferred embodiment, the second spiral conveying mechanism is located below the garbage temporary storage box, a conveying box body is sleeved on the outer side of the second spiral conveying mechanism, and a liquid garbage conveying port connected to a garbage conveying pipeline is opened below the conveying box body.

[0027] The effect of the above scheme is that through the above arrangement, more efficient and convenient transportation and processing of garbage is achieved, thereby improving the overall performance and operation efficiency of the system. First, the second spiral conveying mechanism is placed below the temporary storage box of garbage, and gravity is used to accelerate the falling of garbage, which speeds up the transportation speed and efficiency of garbage, reduces the stagnation and blockage of garbage during transportation, and improves the stability and reliability of the conveying system. Secondly, a conveying box is sleeved on the outside of the second spiral conveying mechanism, which can effectively collect and fix the debris and residues generated during the transportation process, prevent them from causing damage or blockage to the conveying mechanism and pipeline, and ensure the continuous and stable operation of the conveying system. Finally, a liquid garbage conveying port connected to the garbage conveying pipeline is opened below the conveying box, making the discharge of garbage more convenient and rapid, entering the subsequent processing system, shortening the processing cycle, and improving the processing efficiency. Therefore, the scheme realizes the efficient, smooth and reliable process of garbage transportation and processing by optimizing the conveying structure and pipeline design, and provides an effective technical solution for solving the problem of low garbage processing efficiency in the existing system.

[0028] In a further preferred embodiment, the system further comprises a constant temperature slag storage box, which is connected to the three-phase oil-water separator and is used to store the separated wet slag.

[0029] The effect of the above scheme is that through the design and application of the constant temperature slag storage box, the wet slag after separation is effectively stored and kept warm, thereby maintaining the stability and quality of the wet slag, and improving the utilization value of the wet slag and the subsequent processing efficiency. First, the constant temperature slag storage box is connected to the three-phase oil-water separator, which can directly receive and store the wet slag separated from the three-phase oil-water separator, avoiding the secondary transportation and transfer process of the wet slag, reducing the waste of energy and resources, and reducing the processing cost. Secondly, the constant temperature slag storage box has a constant temperature function, which can control and adjust the constant temperature of the wet slag as needed, ensuring that the wet slag maintains a stable temperature state during storage, preventing quality loss or deterioration caused by temperature changes, and ensuring the quality and availability of the wet slag. Finally, through the application of the constant temperature slag storage box, the long-term storage and preservation of the wet slag can be realized, which meets the demand for the storage time of the wet slag in the production and processing process, and at the same time provides sufficient time and space for the subsequent utilization and processing of the wet slag, maximizing the resource value and economic benefits of the wet slag. Therefore, this solution effectively solves the storage and insulation problems in the wet slag treatment process through the use of constant temperature slag storage boxes, improves the utilization efficiency and resource recovery rate of wet slag, and has significant technical and economic benefits.

[0030] In a further preferred embodiment, the system further comprises a constant temperature oil storage tank, which is connected to the three-phase oil-water separator and is used for storing the separated oil.

[0031] The effect of the above scheme is that through the design and application of the constant temperature oil storage tank, the separated grease is effectively stored and kept warm, thereby maintaining the quality and stability of the grease, and improving its utilization value and subsequent processing efficiency. First, the constant temperature oil storage tank is connected to the three-phase oil-water separator, which can directly receive and store the grease separated from the separator, avoiding the secondary transportation and transportation process of the grease, reducing the waste of energy and resources, and reducing the processing cost. Secondly, the constant temperature oil storage tank has a constant temperature function, which can control and adjust the constant temperature of the grease as needed, ensuring that the grease maintains a stable temperature state during storage, preventing quality loss or deterioration caused by temperature changes, and ensuring the quality and availability of the grease. Finally, through the application of the constant temperature oil storage tank, the long-term storage and preservation of the grease can be achieved, meeting the demand for grease storage time during production and processing, while providing sufficient time and space for the subsequent utilization and processing of the grease, maximizing the resource value and economic benefits of the grease. Therefore, this solution effectively solves the storage and insulation problems in the oil and fat processing process through the use of constant temperature oil storage tanks, improves the utilization efficiency and resource recovery rate of oil and fat, and has significant technical and economic benefits.

[0038] The utility model provides a negative pressure pipeline collection and treatment system for kitchen waste. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0039] The utility model provides a negative pressure pipeline collection and processing system for restaurant kitchen waste, such as Figure 1As shown, it includes: a garbage disposal box, a garbage conveying pipeline, a negative pressure power device 200, a crushing pulping machine 300 and a three-phase oil-water separator 400; the crushing pulping machine 300 is connected to the garbage disposal box and is used to crush and pulp the kitchen waste; the three-phase oil-water separator 400 is connected to the crushing pulping machine 300 and is used to separate oil from the prepared pulp.

[0040] The system design provided by the utility model focuses on the process from the delivery of kitchen waste to the separation of grease, thus realizing a complete processing process.

[0041] First, the kitchen waste is put into the waste disposal box. Once the waste in the box reaches a certain level, the waste conveying pipeline starts to operate and conveys the waste from the box to the crushing pulping machine 300.

[0042] The crushing pulping machine 300 plays a key role. After the food waste enters the crushing pulping machine 300, it is processed by the crushing mechanism to crush the waste and make it into a pulp-like substance. In this process, due to the high-speed rotation and special structure inside the machine (to be described in detail below), the grease in the solid waste is released and mixed with water to form a pulp-like substance.

[0043] Next, the slurry enters the three-phase oil-water separator 400. This separator uses high-speed centrifugal force to completely separate the residue, grease and water in the slurry. Through this step, the grease in the solid waste can be completely separated, thereby reducing the grease residue rate and improving the purity of the grease.

[0044] The entire process achieves continuous processing from the delivery of food waste to the separation of grease through the organic coordination of various components in the system, effectively solving the problem of poor grease separation in the existing system, improving resource recovery efficiency, and reducing the difficulty and cost of subsequent processing.

[0045] In a further preferred embodiment of the utility model, the system may also include a constant temperature slag storage box 700, a constant temperature oil storage tank 600 and a liquid storage tank 500, wherein the constant temperature slag storage box 700 is used to store wet slag separated from the slurry, the constant temperature oil storage tank 600 is used to store oil separated by the three-phase oil-water separator 400, and the liquid storage tank 500 is used to store separated wastewater.

[0046] In specific implementation, the constant temperature slag storage box 700 is connected to the three-phase oil-water separator 400 to store the separated wet slag. Its specific functions and advantages are as follows:

[0047] The constant temperature slag storage box 700 is directly connected to the three-phase oil-water separator 400, which can immediately receive and store the separated wet slag, avoiding the secondary transportation and transfer process of the wet slag, reducing the waste of energy and resources, and reducing the processing cost;

[0048] The box has a constant temperature function, which can control and adjust the wet slag to a constant temperature according to needs, ensuring that the wet slag maintains a stable temperature during storage, preventing quality loss or deterioration caused by temperature changes, and ensuring the quality and availability of the wet slag;

[0049] The constant temperature slag storage box 700 can realize long-term storage and preservation of wet slag, meet the demand for wet slag storage time during production and processing, and provide sufficient time and space for subsequent utilization and processing of wet slag, so as to maximize the resource value and economic benefits of wet slag.

[0050] In specific implementation, the constant temperature oil storage tank 600 is connected to the three-phase oil-water separator 400 to store the separated oil. Its specific functions and advantages are as follows:

[0051] The constant temperature oil storage tank 600 is connected to the three-phase oil-water separator 400, and can instantly receive and store the oil separated from the separator, avoiding the secondary transportation and transfer process of the oil, reducing the waste of energy and resources, and reducing the processing cost;

[0052] The oil storage tank has a constant temperature function, which can control and adjust the constant temperature of the oil according to the needs, ensuring that the oil maintains a stable temperature during storage, preventing quality loss or deterioration caused by temperature changes, and ensuring the quality and availability of the oil;

[0053] The constant temperature oil storage tank 600 can be used to achieve long-term storage and preservation of oils and fats, meeting the demand for oil storage time during production and processing, while providing sufficient time and space for subsequent utilization and processing of oils and fats, thereby maximizing the resource value and economic benefits of oils and fats.

[0054] The working process of the negative pressure pipeline collection and treatment system for kitchen waste is preferably as follows:

[0055] The restaurant kitchen waste is transported from the delivery port to the processing room through the negative pressure pipe system;

[0056] In the processing room, the garbage is first crushed and pulped by a crushing pulping machine 300;

[0057] The prepared slurry enters the three-phase oil-water separator 400 to separate the residue, grease and waste water;

[0058] The separated wastewater directly enters the liquid storage tank 500 for storage;

[0059] The dehydrated wet slag is directly stored in the constant temperature slag storage box 700, avoiding the secondary transportation of the wet slag;

[0060] The separated grease is directly stored in the constant temperature oil storage tank 600.

[0061] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the crushing pulping machine 300 includes the following main components: a garbage receiving box 310, a first motor 320, a first screw conveying mechanism 330, a crushing mechanism 340, a filtering mechanism 350 and a second screw conveying mechanism 360. The garbage receiving box 310 is connected to the garbage conveying pipeline and is used to receive and preliminarily store the food waste from the conveying pipeline. The first motor 320 drives the first screw conveying mechanism 330, and by providing power to rotate it, the food waste is conveyed to the crushing mechanism 340. The first screw conveying mechanism 330 is located downstream of the garbage receiving box 310, and is driven by the first motor 320 to convey the food waste to the crushing mechanism 340 along a predetermined path. The crushing mechanism 340 is arranged downstream of the first screw conveying mechanism 330, and crushes the food waste to make it into a slurry. The filtering mechanism 350 is located between the crushing mechanism 340 and the second screw conveying mechanism 360, and uses a multi-stage filter screen or a centrifugal separation device to further purify the slurry to remove solid particles, impurities and residual grease therein. The second screw conveying mechanism 360 is disposed downstream of the filtering mechanism 350, receives the filtered pulp and conveys it to the next processing link, such as the three-phase oil-water separator 400. The crushing pulping machine 300 also includes: a second motor 380, which is used to drive the second screw conveying mechanism 360 to rotate.

[0062] The garbage receiving box 310 can effectively receive and transport the food waste to the subsequent processing equipment by connecting with the garbage conveying pipeline. The first motor 320 drives the first spiral conveying mechanism 330 to rotate, and transports the food waste to the crushing mechanism 340 along the pipeline. The crushing mechanism 340 is located downstream of the first spiral conveying mechanism 330, and crushes the food waste to make it into a slurry. Subsequently, the crushed food waste slurry enters the filtering mechanism 350, which is located between the crushing mechanism 340 and the second spiral conveying mechanism 360. The filtering mechanism 350 can further remove solid particles, impurities and residual grease in the slurry to improve the purity of the slurry. Finally, the filtered food waste slurry is transported to the next link through the second spiral conveying mechanism 360.

[0063] Through the design of the crushing mechanism 340, the kitchen waste can be fully crushed and made into a slurry, which is conducive to releasing the grease fused in the solid waste and improving the separation efficiency of the grease. The setting of the filtering mechanism 350 can further filter the slurry, remove the solid particles, impurities and residual grease therein, improve the separation purity of the grease, and reduce the residual grease rate. The design of the first spiral conveying mechanism 330 and the second spiral conveying mechanism 360 enables the entire processing process to be carried out continuously, improves the processing efficiency, and reduces energy consumption and costs. The reasonable connection and layout of each component constitute a complete processing system, which can effectively complete the entire processing process from kitchen waste collection to grease separation, and improves the stability and reliability of the system.

[0064] Furthermore, the crushing mechanism 340 includes: a garbage temporary storage box 341 (such as Figure 4 As shown), the crushing gear 342, the linkage shaft 343 and the crushing rod 344, as shown Figure 5 As shown. The garbage temporary storage box 341 is arranged at the outer edge of the first spiral conveying mechanism 330 and is connected to the garbage receiving box body 310, and is used to temporarily store the food and kitchen waste conveyed from the first spiral conveying mechanism 330. The crushing gear 342 is arranged in the garbage temporary storage box 341 and shares a rotating shaft with the first spiral conveying mechanism 330. The linkage shaft 343 is connected to the crushing gear 342 and rotates with the crushing gear 342. The crushing rod 344 is sleeved on the outer edge of the linkage shaft 343 and is responsible for fully crushing and squeezing the garbage.

[0065] The garbage temporary storage box 341 ensures the continuous supply of food waste, thereby preventing incomplete crushing due to uneven transportation. The crushing gear 342 shares a rotating shaft with the first spiral conveying mechanism 330, and the crushing gear 342 is linked with the crushing rod 344 through the linkage shaft 343 to ensure that the crushing process is carried out synchronously. The rotation of the crushing gear 342 drives the crushing rod 344 to rotate, fully crushing and squeezing the garbage, especially releasing the grease fused in the solid garbage. The crushing rod 344 rotates with the rotation of the crushing gear 342, forming an efficient crushing force, so that all food waste is fully crushed into fine particles, ensuring the uniformity and purity of the slurry.

[0066] Therefore, by setting up the temporary garbage storage box 341, the continuous supply of garbage is guaranteed to prevent incomplete crushing. The design of the crushing gear 342 and the first spiral conveying mechanism 330 sharing the same rotating shaft realizes the linkage between the crushing gear 342 and the crushing rod 344 through the linkage shaft 343, ensuring the synchronization of the crushing process, thereby improving the crushing efficiency. The combination of the crushing rod 344 and the crushing gear 342 forms an efficient crushing force in the temporary garbage storage box 341, so that the food waste is fully crushed into fine particles, which helps to improve the uniformity and purity of the slurry. In this way, in the subsequent solid-liquid separation and oil-water separation process, the separation efficiency and oil purity are improved, the resource recovery efficiency is improved, and the difficulty and cost of subsequent processing are reduced. Therefore, by optimizing the structural design of the crushing mechanism 340, this scheme significantly improves the release and separation effect of oil in food waste.

[0067] Preferably, there are multiple linkage shafts 343, and these linkage shafts 343 are arranged in a circumferential array on the outer edge of the transmission shaft of the first screw conveying mechanism 330. A plurality of crushing rods 344 are sleeved on each linkage shaft 343, and multiple crushing rods 344 form a crushing coaxial rod group on the same linkage shaft 343. Through such an arrangement and design, the working area and crushing efficiency of the crushing mechanism 340 are effectively improved.

[0068] The arrangement of multiple linkage shafts 343 enables the crushing mechanism 340 to be evenly stressed during operation, thus avoiding the problem of damage or low working efficiency caused by uneven stress on a single linkage shaft 343. The design of the crushing rod 344 is also crucial. The multiple crushing rods 344 sleeved on each linkage shaft 343 together form a crushing coaxial rod group, making the crushing force more uniform and powerful. When the crushing mechanism 340 is running, these crushing rods 344 fully crush the garbage by rotating, effectively releasing the grease in the solid garbage, and ensuring the smooth progress of the subsequent separation process.

[0069] Therefore, the utility model arranges multiple linkage shafts 343 in a circular array and sets multiple crushing rods 344 on each linkage shaft 343, which not only increases the working area and crushing efficiency of the crushing mechanism 340, but also ensures the stability and reliability of the crushing process. Such a design makes the crushing force uniform and strong, which helps to fully crush the solid waste, thereby improving the release efficiency of grease. Ultimately, this optimized structural design significantly improves the working efficiency and stability of the crushing mechanism 340, thereby improving the overall performance of the system and the grease separation effect, and effectively solves the problems of incomplete crushing and poor grease separation effect during the treatment of food waste.

[0070] Furthermore, there are multiple crushing gears 342, and a crushing circumferential rod group is provided between adjacent crushing gears 342. The crushing circumferential rod group is composed of crushing rods 344 on different crushing coaxial rod groups on the same vertical plane. Such a design expands the overall structure of the crushing mechanism 340 through the combination of multiple crushing gears 342 and crushing circumferential rod groups, making it work more comprehensive and efficient.

[0071] When the pulverizing mechanism 340 is in operation, the pulverizing circumferential rod group between adjacent pulverizing gears 342 can evenly pulverize the solid waste. The pulverizing circumferential rod group is composed of pulverizing rods 344 on different pulverizing coaxial rod groups on the same vertical plane. This layout design makes the pulverizing rods 344 have a more comprehensive range of action and can apply the pulverizing force more evenly. Through this uniform and comprehensive pulverizing process, the solid waste can be fully pulverized, especially the internal fused grease can be effectively released, ensuring that the subsequent separation process is smoother and more efficient.

[0072] It can be seen that the utility model not only increases the working area and efficiency of the pulverizing mechanism 340 by optimizing the setting of the pulverizing gear 342 and the layout of the pulverizing circumferential rod group, but also ensures the uniformity and stability of the pulverizing process. The design of the pulverizing circumferential rod group makes the pulverization of solid waste more thorough, improves the uniformity and purity of the slurry, and thus improves the separation efficiency and oil purity in the subsequent solid-liquid separation and oil-water separation processes. Ultimately, this optimized design significantly improves the working efficiency and stability of the pulverizing mechanism 340, enhances the overall performance of the system and the oil separation effect, and effectively solves the problems of incomplete pulverization and poor oil separation effect during the treatment of food waste.

[0073] Specifically, the crushing mechanism 340 is provided with two crushing circumferential rod groups between adjacent crushing gears 342. The two crushing circumferential rod groups are composed of a plurality of crushing rods 344, and the crushing rods 344 are evenly distributed on different crushing coaxial rod groups on the same vertical plane. Through this arrangement, the structure of the crushing mechanism 340 is more complex and sophisticated, and can cover a larger working area during operation.

[0074] When the pulverizing mechanism 340 is in operation, the food waste first enters the pulverizing gear 342 area, where the waste undergoes a preliminary pulverizing process. Subsequently, the waste is transferred to the two pulverizing circumferential rod groups between the adjacent pulverizing gears 342. The two pulverizing circumferential rod groups further pulverize the waste through the coordinated work of multiple pulverizing rods 344. Since the two pulverizing circumferential rod groups can provide more pulverizing rods 344, they can apply the pulverizing force more evenly and continuously, thereby ensuring that the waste is fully pulverized. In particular, the grease in the solid waste can be effectively released in this process, preparing for the subsequent separation process.

[0075] By setting two crushing circumferential rod groups between adjacent crushing gears 342, the working efficiency and crushing uniformity of the crushing mechanism 340 are significantly improved. Compared with the design of only setting one crushing circumferential rod group, this configuration of two groups of crushing circumferential rod groups can increase the working area of ​​the crushing mechanism 340, improve the crushing efficiency, and ensure that the garbage crushing process is more thorough and uniform. Ultimately, this optimized design not only improves the release and separation effect of grease, but also enhances the overall performance and stability of the system, and reduces the processing difficulty and cost. By increasing the number of crushing circumferential rod groups, the efficiency and uniformity of the crushing mechanism 340 are effectively improved, thereby significantly improving the overall performance and grease separation effect of the system.

[0076] Preferably, the filter mechanism 350 includes a filter box 351 (such as Figure 5 As shown) and filter plate 352 (as Figure 4 ). The filter plate 352 is designed to be arc-shaped and fits on the inner wall of the filter box 351, and a plurality of filter holes are arranged in an array on the filter plate 352. This design enables the filter plate 352 to form a tight filter layer in the filter box 351, providing an effective structural basis for filtering the liquid.

[0077] When the liquid enters the filter mechanism 350, it first contacts the filter plate 352. Since the filter plate 352 is in an arc shape, the area through which the liquid flows is increased, so that the liquid can flow on a larger surface. The filter holes on the filter plate 352 are arranged in an array to ensure that the liquid can pass through each filter hole evenly. As the liquid flows through these filter holes, impurities are trapped on the surface of the filter plate 352, while pure liquid flows out through the filter holes. This structural design not only increases the filtration efficiency, but also ensures the uniformity of the liquid flow rate, avoiding the problem of uneven filtration caused by excessive local flow rate.

[0078] The filter mechanism 350 achieves an efficient filtering effect through the design of the arc-shaped filter plate 352 and the array arrangement of the filter holes. The arc-shaped filter plate 352 provides a larger contact area, so that the liquid has a more complete contact with the filter plate 352 during the flow process, thereby increasing the removal rate of impurities. At the same time, the uniform arrangement of the filter holes ensures that the liquid can pass evenly, improving the uniformity and stability of the filtration. Overall, this solution significantly improves the filtration efficiency and filtration quality, ensures the purity and stability of the liquid during the system processing process, and thus enhances the overall performance and reliability of the system.

[0079] Preferably, the second spiral conveying mechanism 360 is located below the temporary garbage storage box 341, and is provided with a conveying box body 370 on the outside. A liquid garbage conveying port is provided below the conveying box body 370 for connecting to a garbage conveying pipeline. This design enables the second spiral conveying mechanism 360 to better handle the garbage falling from the temporary garbage storage box 341, and conveniently convey the liquid garbage to the next processing link.

[0080] When the garbage falls from the temporary storage box, the second spiral conveying mechanism 360 uses gravity to accelerate the falling process of the garbage and quickly conveys the garbage to the conveying box 370. The conveying box 370 not only collects the garbage, but also plays a fixing role to prevent debris and residues from causing damage or blockage during the conveying process. The liquid garbage is discharged through the liquid garbage conveying port below the conveying box 370 and enters the connected garbage conveying pipeline, ensuring that the liquid garbage can be quickly and conveniently conveyed to the subsequent processing system.

[0081] The utility model achieves more efficient and convenient garbage transportation and treatment by optimizing the position and structural design of the second spiral conveying mechanism 360. The use of gravity speeds up the falling speed of garbage, improves the conveying efficiency, reduces stagnation and blockage, and improves the stability of the system. The setting of the conveying box 370 effectively collects and fixes debris during the conveying process to prevent damage to the conveying mechanism and pipeline. The design of the liquid garbage conveying port enables liquid garbage to be quickly discharged and enter the subsequent processing link, shortening the processing cycle and improving the processing efficiency. This optimization significantly improves the performance and operating efficiency of the system and solves the problem of low garbage treatment efficiency in the existing system.
