Description

Technical Field

[0001] The present invention relates to the technical field of garbage recycling, and in particular to an intelligent kitchen waste recycling system. Background Art

[0002] With the improvement of people's living standards and the rapid development of the catering industry, the amount of food waste is increasing. Food waste has the characteristics of high water content, high organic matter content, easy to rot and stink. If it is not handled properly, it will cause serious pollution to the environment. At present, the traditional food waste treatment methods mainly include landfill, incineration and composting. However, these methods have some problems, such as landfill will occupy a lot of land resources and may pollute groundwater; incineration will produce harmful gases such as dioxins, which will harm the environment and human health; composting treatment cycle is long, and the classification requirements of garbage are high. The existing garbage recycling system is often not accurate enough when classifying food waste, and it is easy to mix recyclables (such as bottles) with food waste, resulting in waste of resources and increased difficulty in subsequent treatment. The traditional garbage recycling system usually adopts manual sorting or simple mechanical sorting, which has low processing efficiency and cannot meet the growing demand for food waste treatment.

[0003] Chinese patent application publication number: CN113118184B discloses an environmentally friendly intelligent kitchen waste treatment system and treatment method, including a base, a drying device and a crushing device, wherein the drying device is arranged on the upper surface of the base, and the crushing device is arranged above the drying device. The invention can solve the existing problems: since the kitchen waste contains a large amount of water after recycling, and the existing drying equipment needs to manually turn the kitchen waste when heating and drying the kitchen waste with a high water content so that it can be dried thoroughly, but there are many harmful substances in the kitchen waste, and manual turning of the kitchen waste will cause certain personal injuries, and the manual turning effect is poor; since the kitchen waste is mixed with various food residues and has a certain viscosity, simply heating and drying it is time-consuming and laborious, and the existing drying equipment does not have the function of crushing the kitchen waste, thereby reducing the drying efficiency of the kitchen waste and worsening the effect.

[0004] It can be seen that the existing technology cannot effectively distinguish the seasoning bottles in the food waste, which leads to the need for secondary sorting of the food waste during subsequent processing, resulting in low efficiency in food waste processing. Summary of the invention

[0005] To this end, the present invention provides an intelligent kitchen waste recycling system to overcome the problem in the prior art that seasoning bottles in kitchen waste cannot be effectively distinguished, resulting in the need for secondary sorting of the kitchen waste during subsequent processing, resulting in low kitchen waste processing efficiency.

[0006] To achieve the above object, the present invention provides an intelligent kitchen waste recycling system, comprising:

[0007] The garbage collection module includes a filter for filtering garbage and a double-layer garbage container for carrying garbage.

[0008] A classification conveying module, which is connected to the garbage collection module, comprises a first conveying pipeline for conveying garbage from the upper layer of the double-layer garbage container to the water-filled separation module, and a second conveying pipeline for conveying garbage from the lower layer of the double-layer garbage container to the food and kitchen waste treatment area;

[0009] A water-filled separation module, which is connected to the classification and conveying module, comprises a separation water tank for receiving garbage from the upper layer of the double-layer garbage container, a water-filling device for filling the separation water tank with water, a water flow circulation device for circulating the water flow in the separation water tank, and a floating collection device for collecting garbage on the water surface of the separation water tank, wherein the water flow circulation device comprises a water pump, a pipeline, and a water flow guide component;

[0010] A distinguishing module, which is connected to the water-filled separation module, and includes a speed detection device for detecting the moving speed of garbage in real time, and a mechanical grabbing device for grabbing garbage under the water surface of the separation tank;

[0011] A control module, which is respectively connected to the garbage collection module, the classification and transportation module, the water filling and separation module and the differentiation module, comprises:

[0012] A conveying start control unit, which is used to determine whether to start the classification conveying module according to the weight of the garbage in the double-layer garbage container and whether there is stacking in the upper layer of garbage;

[0013] A garbage type determination unit, which is used to determine the garbage type according to the moving speed of the garbage under the water surface of the separation tank, and the garbage type includes bottle type and solid kitchen waste type;

[0014] The adjustment unit is used to determine whether to adjust the preset moving speed or the water pump power according to the weight proportion of bottle-type garbage appearing in the food waste treatment area within a preset time period and whether bottle-type garbage appears to be aggregated in the garbage collected under the water surface at a single time.

[0015] Furthermore, the conveying start control unit starts the classification conveying module under the condition that the weight of garbage in the double-layer garbage container is greater than or equal to a preset garbage weight or stacking occurs in the upper layer of garbage.

[0016] Furthermore, the preset garbage weight is determined according to the garbage weight when the double-layer garbage container is filled with garbage.

[0017] Furthermore, the water-filled separation module transports the garbage on the water surface of the separation tank collected by the floating collection device to the bottle type garbage recycling area.

[0018] Furthermore, the garbage type determination unit determines the garbage type according to the moving speed of the garbage under the water surface of the separation tank, including determining that the garbage type is a bottle type under the condition that the moving speed of the garbage under the water surface of the separation tank is greater than or equal to a preset moving speed, or determining that the garbage type is a solid food waste type under the condition that the moving speed of the garbage under the water surface of the separation tank is less than a preset moving speed.

[0019] Furthermore, the mechanical grabbing device grabs bottle type garbage from under the water surface of the separation tank to the bottle type garbage recycling area.

[0020] Further, the adjustment unit determines the adjustment of the preset moving speed or the water pump power, including, under the condition that the weight proportion of bottle type garbage appearing in the food waste treatment area within the preset time period is greater than or equal to the preset weight proportion, and there is no aggregation of bottle type garbage in the garbage collected under the water surface in a single time, determining the adjustment of the preset moving speed, or, under the condition that the weight proportion of bottle type garbage appearing in the food waste treatment area is greater than or equal to the preset weight proportion, and there is aggregation of bottle type garbage in the garbage collected under the water surface in a single time, determining the adjustment of the water pump power.

[0021] Furthermore, the adjustment amount of the water pump power is positively correlated with the weight proportion of bottle type garbage appearing in the food waste treatment area, and the adjustment amount of the preset moving speed is negatively correlated with the weight proportion of bottle type garbage appearing in the food waste treatment area.

[0022] Furthermore, the differentiation module filters out moisture after the mechanical grasping device grasps the bottle-type garbage, and transports the garbage after the moisture is filtered out to the solid food and kitchen waste treatment area.

[0023] Furthermore, a vibration device is installed at the first conveying pipeline and the second conveying pipeline to start vibration when blockage occurs, and to judge whether blockage occurs when the pipeline pressure is greater than the historical average pressure of the corresponding pipeline when conveying garbage.

[0024] Compared with the prior art, the beneficial effect of the present invention lies in that, by setting a preset garbage weight and judging the stacking phenomenon of upper garbage, the system can not start the classification and conveying module when the garbage amount has not reached a certain level, so that it can avoid frequent starting of the equipment when the garbage amount is small, thereby reducing equipment wear and energy consumption, and improving the overall operation efficiency of the system. For example, in a time period when the amount of garbage generated is small, the system can remain in a standby state until the amount of garbage meets the starting conditions before starting to run, saving energy and equipment maintenance costs. When the system intelligently decides whether to start the classification and conveying module according to the garbage weight and stacking situation, resources can be better allocated. By monitoring the stacking phenomenon of upper garbage, situations that may cause system failures can be discovered in time. For example, if the upper garbage is stacked too high, it may affect the screening effect of the filter screen and even cause garbage overflow. Timely starting of the classification and conveying module can avoid the occurrence of these problems and improve the reliability of the system. The above method can effectively distinguish the seasoning bottles in the kitchen waste to avoid the need for secondary sorting of the kitchen waste in subsequent processing, thereby improving the efficiency of kitchen waste processing.

[0025] Furthermore, the present invention realizes the preliminary separation and recycling of recyclable bottles by transporting the garbage on the water surface collected by the floating collection device to the bottle type garbage recycling area, which helps to improve the recycling rate of resources and reduce resource waste. The garbage under the water surface is classified according to the moving speed, and the bottle type and solid food waste type can be accurately distinguished. This accurate classification can make different types of garbage enter the treatment process that is most suitable for them. For bottle type garbage, a series of recycling and utilization treatments such as cleaning, crushing, and re-granulation can be carried out; for solid food waste type, composting, anaerobic fermentation and other treatments can be carried out to produce organic fertilizer or bioenergy, thereby improving the treatment efficiency and effect of the entire food waste treatment system. The above method can effectively distinguish the seasoning bottles in the food waste, avoid the need for secondary sorting of the food waste during subsequent treatment, and thus improve the food waste treatment efficiency.

[0026] Furthermore, the present invention can accurately distinguish and specifically capture the types of garbage, and subsequently adopt a treatment method that is more suitable for the characteristics of bottles and solid food waste. The preset moving speed or water pump power is adjusted according to the weight proportion of bottle-type garbage in the food waste treatment area and the aggregation phenomenon of bottle-type garbage in the underwater garbage collected at a time. The system can dynamically respond according to the actual processing feedback. For example, if it is found that the proportion of bottles in the food waste treatment area is too high and there is no aggregation phenomenon of bottle-type garbage in the underwater garbage collected at a time, it means that the garbage classification is When the preset moving speed is too high, bottle type garbage is misjudged as solid food waste. At this time, the preset moving speed is adjusted with the first adjustment coefficient. If it is found that the proportion of bottles in the food waste treatment area is too high and bottle type garbage is aggregated in the underwater garbage collected in a single time, it means that the bottle garbage is blocked and cannot move, causing the bottle type garbage to be misjudged as solid food waste. At this time, the water pump power is increased with the second adjustment coefficient. The above method can effectively distinguish the seasoning bottles in the food waste, avoid the need for secondary sorting of the food waste in the subsequent treatment, thereby improving the food waste treatment efficiency.

[0027] Furthermore, the present invention installs a vibration device at the first conveying pipeline and the second conveying pipeline, and judges the blockage situation based on the pipeline pressure being greater than the historical average pressure when the corresponding pipeline conveys garbage. This design can timely and accurately detect pipeline blockage problems. Once blockage occurs, the system can quickly start the vibration device to loosen the accumulated garbage through vibration, restore the normal conveying function of the pipeline, avoid garbage accumulation and overflow caused by pipeline blockage, and affect the normal operation of the entire kitchen waste recycling system. By timely detecting and handling the blockage problem, the further deterioration of the blockage situation is prevented. Because long-term blockage may cause damage to the pipeline (such as pipeline deformation, rupture, etc.), and may also affect other equipment connected to it (such as delivery pumps, etc. damaged due to overload), timely dredging measures reduce these potential equipment loss risks, correspondingly reduce the cost of equipment maintenance and replacement, extend the service life of the entire conveying system, and improve the stability and reliability of the system.

[0040] The intelligent kitchen waste recycling system of the embodiment of the present invention comprises:

[0041] The garbage collection module includes a filter 2 for filtering garbage and a double-layer garbage container 1 for carrying garbage.

[0042] A classification conveying module, which is connected to the garbage collection module, comprises a first conveying pipeline 3 for conveying garbage from the upper layer of the double-layer garbage container to the water-filled separation module, and a second conveying pipeline 4 for conveying garbage from the lower layer of the double-layer garbage container to the food waste treatment area 8;

[0043] A water-filled separation module, which is connected to the classification and conveying module, comprises a separation water tank 5 for receiving garbage from the upper layer of the double-layer garbage container, a water-filling device for filling the separation water tank with water, a water circulation device (not shown in the figure) for circulating the water flow in the separation water tank, and a floating collection device (not shown in the figure) for collecting garbage on the water surface of the separation water tank, wherein the water circulation device comprises a water pump, a pipeline and a water flow guide component;

[0044] A distinguishing module, which is connected to the water-filled separation module, includes a speed detection device (not shown in the figure) for detecting the moving speed of garbage in real time, and a mechanical grabbing device (not shown in the figure) for grabbing the garbage under the water surface of the separation tank;

[0045] A control module, which is respectively connected to the garbage collection module, the classification and transportation module, the water filling and separation module and the differentiation module, comprises:

[0046] A conveying start control unit, which is used to determine whether to start the classification conveying module according to the weight of the garbage in the double-layer garbage container and whether there is stacking in the upper layer of garbage;

[0047] A garbage type determination unit, which is used to determine the garbage type according to the moving speed of the garbage under the water surface of the separation tank, and the garbage type includes bottle type and solid kitchen waste type;

[0048] The adjustment unit is used to determine whether to adjust the preset moving speed or the water pump power according to the weight proportion of bottle-type garbage appearing in the food waste treatment area within a preset time period and whether bottle-type garbage appears to be aggregated in the garbage collected under the water surface at a single time.

[0049] In the embodiment of the present invention, the filter screen can be a metal mesh filter screen with a certain aperture size (for example, 10 cm × 10 cm). When garbage is poured into a double-layer garbage container, the garbage on the upper layer of the double-layer garbage container is intercepted by the filter screen, and small-volume garbage falls into the lower layer of the container through the filter screen; the first conveying pipeline can be a stainless steel pipeline with a diameter of 20 cm, and the second conveying pipeline can be a stainless steel pipeline with a diameter of 15 cm; the water filling device can be a spray system composed of multiple nozzles, which is installed above the separation tank. The nozzle can be connected to the water source through a pipeline. When the garbage on the upper layer of the double-layer garbage container enters the separation tank, the nozzle starts to spray water, causing the water level in the tank to rise, thereby realizing water filling and separation. The floating collection device can be a collection net with a mechanical arm, which is installed above the water surface of the separation tank. When the garbage on the water surface floats up, the robotic arm will automatically lower the collection net to collect the garbage, then lift it to a certain height and transport it to the bottle type garbage recycling area; the speed detection device can be an underwater laser speed meter installed in the underwater part of the separation tank. When the garbage moves in the water, the laser speed meter will emit a laser beam and calculate the movement speed of the garbage by measuring the reflection time of the laser beam; the mechanical grasping device can be a grasping device composed of a robotic arm and a clamp, which is installed in the underwater part of the separation tank. When the speed detection device determines that the garbage type is a bottle type, the robotic arm will According to the instruction, the clamp is moved to the corresponding position, the bottle is clamped and lifted above the water surface, and then transported to the bottle type garbage recycling area; the present invention also installs a water pump, a pipeline and corresponding water flow guiding components inside the separation tank to construct a water flow circulation device, and the judgment of whether the upper garbage is stacked can be determined by installing a camera. The solid food waste treatment area includes but is not limited to "composting treatment area, anaerobic fermentation area and feed processing area"; the bottle type garbage recycling area includes but is not limited to "plastic bottle recycling area, glass bottle recycling area and metal bottle recycling area".

[0050] Specifically, the conveying start control unit determines whether to start the classification conveying module, including determining whether to start the classification conveying module according to the comparison result of the garbage weight in the double-layer garbage container with the preset garbage weight and whether stacking occurs in the upper layer of garbage;

[0051] If the weight of the garbage in the double-layer garbage container is greater than or equal to the preset garbage weight or there is a stacking phenomenon in the upper layer of garbage, the conveying start control unit determines to start the classification conveying module;

[0052] If the weight of the garbage in the double-layer garbage container is less than the preset garbage weight and there is no stacking phenomenon in the upper layer of garbage, the conveying start control unit determines not to start the classification conveying module.

[0053] The preset garbage weight in the embodiment of the present invention is nine-tenths of the garbage weight when the double-layer garbage container is full of garbage, but the above value is not limited to this, and those skilled in the art can also adjust the value according to actual needs.

[0054] The present invention sets a preset garbage weight and determines the stacking phenomenon of upper garbage. The system may not start the classification and conveying module when the amount of garbage has not reached a certain level. This can avoid frequent startup of the equipment when the amount of garbage is small, thereby reducing equipment wear and energy consumption and improving the overall operation efficiency of the system. For example, in a time period when the amount of garbage generated is small, the system can remain in a standby state until the amount of garbage meets the startup conditions, saving energy and equipment maintenance costs. When the system intelligently decides whether to start the classification and conveying module based on the garbage weight and stacking situation, resources can be better allocated. By monitoring the stacking phenomenon of upper garbage, situations that may cause system failures can be discovered in time. For example, if the upper garbage is stacked too high, it may affect the screening effect of the filter and even cause garbage overflow. Timely activation of the classification and conveying module can avoid these problems and improve the reliability of the system. The above method can effectively distinguish the seasoning bottles in the kitchen garbage to avoid the need for secondary sorting of the kitchen garbage during subsequent processing, thereby improving the efficiency of kitchen garbage processing.

[0055] Specifically, the water-filled separation module transports the garbage on the water surface of the separation tank collected by the floating collection device to the bottle type garbage recycling area 7.

[0056] Specifically, the garbage type determination unit determines the garbage type by comparing the moving speed of the garbage under the water surface of the separation tank with a preset moving speed;

[0057] If the moving speed of the garbage under the water surface of the separation tank is greater than or equal to the preset moving speed, the garbage type determination unit determines that the garbage type is a bottle type;

[0058] If the moving speed of the garbage under the water surface of the separation tank is less than a preset moving speed, the garbage type determination unit determines that the garbage type is a solid food and kitchen waste type.

[0059] The preset moving speed in the embodiment of the present invention is the average value of the moving speeds of bottle-type garbage under the water surface under the same water pump power for several times, but the above value is not limited to this, and those skilled in the art can also adjust the value according to actual needs.

[0060] The present invention realizes the preliminary separation and recycling of recyclable bottles by transporting the garbage on the water surface collected by the floating collection device to the bottle type garbage recycling area, which helps to improve the recycling rate of resources and reduce resource waste. The garbage under the water surface is classified according to the moving speed, and the bottle type and the solid kitchen waste type can be accurately distinguished. This accurate classification can make different types of garbage enter the treatment process that is most suitable for them. For the bottle type garbage, a series of recycling and utilization treatments such as cleaning, crushing, and re-granulation can be carried out; for the solid kitchen waste type, composting, anaerobic fermentation and other treatments can be carried out to produce organic fertilizer or bioenergy, thereby improving the treatment efficiency and effect of the entire kitchen waste treatment system. The above method can effectively distinguish the seasoning bottles in the kitchen waste, avoid the need for secondary sorting of the kitchen waste in the subsequent treatment, and thus improve the kitchen waste treatment efficiency.

[0061] Specifically, the mechanical grabbing device grabs bottle-type garbage from under the water surface of the separation tank to the bottle-type garbage recycling area.

[0062] Specifically, the adjustment unit determines to adjust the preset moving speed or the water pump power, including determining to adjust the preset moving speed or the water pump power according to the weight proportion of bottle-type garbage appearing in the food waste treatment area within a preset time period and whether the bottle-type garbage appears to be aggregated in the garbage collected under the water surface at a single time;

[0063] If the weight proportion of bottle-type garbage in the food and kitchen garbage processing area is greater than or equal to the preset weight proportion and there is no aggregation of bottle-type garbage in the garbage collected under the water surface at a single time, the adjustment unit determines to adjust the preset moving speed;

[0064] If the weight proportion of bottle-type garbage in the restaurant and kitchen garbage processing area is greater than or equal to the preset weight proportion and the bottle-type garbage is aggregated in the garbage collected under the water surface at a single time, the adjustment unit determines to adjust the water pump power;

[0065] If the weight proportion of bottle-type garbage in the food waste treatment area is less than a preset weight proportion, the adjustment unit determines that there is no need to adjust the food waste treatment process.

[0066] In the embodiment of the present invention, the value range of the preset weight ratio is 0.1-0.3, the value of the preset weight ratio is preferably 0.2, and the preset duration is set to 5 days, but the above values ​​are not limited to this, and technical personnel in this field can also adjust the value according to actual needs.

[0067] Specifically, under the condition of determining the adjustment of the preset moving speed, the adjustment unit determines to adjust the preset moving speed with a first adjustment coefficient, and under the condition of determining the adjustment of the water pump power, the adjustment unit determines to adjust the water pump power with a second adjustment coefficient.

[0068] In the embodiment of the present invention, the value range of the first adjustment coefficient is set to 0.82-0.95, and the value of the first adjustment coefficient is preferably 0.86. The value range of the second adjustment coefficient is set to 1.05-1.19, and the value of the second adjustment coefficient is preferably 1.12. The adjustment amount of the water pump power is positively correlated with the weight proportion of bottle type garbage appearing in the food waste treatment area, and the adjustment amount of the preset moving speed is negatively correlated with the weight proportion of bottle type garbage appearing in the food waste treatment area. However, the above values ​​are not limited to this, and those skilled in the art may also adjust the values ​​according to actual needs.

[0069] The present invention accurately distinguishes and captures garbage types in a targeted manner, and subsequently, a treatment method that is more suitable for the characteristics of bottles and solid kitchen waste can be adopted for bottles and solid kitchen waste. The preset moving speed or water pump power is adjusted according to the weight proportion of bottle type garbage in the kitchen waste treatment area and the aggregation phenomenon of bottle type garbage in the underwater garbage collected at a time. The system can dynamically respond according to actual processing feedback. For example, if it is found that the proportion of bottles in the kitchen waste treatment area is too high and the bottle type garbage in the underwater garbage collected at a time does not aggregate, it means that the preset moving speed is too high during garbage classification, resulting in the bottle type garbage being misjudged as solid kitchen waste. At this time, the preset moving speed is adjusted with a first adjustment coefficient. If it is found that the proportion of bottles in the kitchen waste treatment area is too high and the bottle type garbage in the underwater garbage collected at a time aggregates, it means that the bottle garbage is blocked and does not move, resulting in the bottle type garbage being misjudged as solid kitchen waste. At this time, the water pump power is increased with a second adjustment coefficient. The above method effectively distinguishes the seasoning bottles in the kitchen waste, avoids the need for secondary sorting of the kitchen waste in the subsequent treatment, and thus improves the kitchen waste treatment efficiency.

[0070] Specifically, the differentiation module filters out moisture after the mechanical grasping device grasps the bottle-type garbage, and transports the filtered garbage to the solid food waste treatment area; a vibration device is also installed at the first conveying pipeline and the second conveying pipeline to start vibration when blockage occurs, and judge that blockage occurs including pipeline pressure being greater than the historical average pressure of the corresponding pipeline when conveying garbage.

[0071] The present invention installs a vibration device at the first conveying pipeline and the second conveying pipeline, and judges the blockage situation according to the pipeline pressure being greater than the historical average pressure when the corresponding pipeline conveys garbage. This design can timely and accurately detect the pipeline blockage problem. Once blockage occurs, the system can quickly start the vibration device to loosen the accumulated garbage through vibration, restore the normal conveying function of the pipeline, avoid garbage accumulation and overflow caused by pipeline blockage, and affect the normal operation of the entire kitchen waste recycling system. By timely detecting and handling the blockage problem, the further deterioration of the blockage situation is prevented. Because long-term blockage may cause damage to the pipeline (such as pipeline deformation, rupture, etc.), and may also affect other equipment connected thereto (such as delivery pumps, etc. damaged due to overload), timely dredging measures reduce these potential equipment loss risks, correspondingly reduce the cost of equipment maintenance and replacement, extend the service life of the entire conveying system, and improve the stability and reliability of the system.
