Description

Technical Field

[0001] This invention relates to the field of food waste treatment technology, and more specifically, to an overflow alarm device, a food waste treatment system, and a blockage treatment method. Background Technology

[0002] In the process of food waste treatment, the conveyor, as the upstream equipment of the extruder, plays a crucial role in transporting food waste to the extruder's feed inlet. When the extruder malfunctions (i.e., "blockage"), if the conveyor continues to feed, material will gradually fill the space between the conveyor and the extruder feed inlet, causing material accumulation and increasing the difficulty of cleaning. Current technology for checking extruder blockage mainly relies on sensors and other detection elements to monitor the material level inside the conveyor or extruder and the pressure on the screen, thereby determining whether there is blockage and overflow.

[0003] However, due to the narrow internal space of the conveyor or extruder, the detection element is affected by external factors such as light, material condition, material layer height or vibration, resulting in low accuracy and poor reliability of blockage detection. This often leads to misjudgment by the detection element, making it unable to detect the phenomenon of blockage and overflow, which can easily cause the kitchen waste treatment system to shut down and affect production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an overflow alarm device, a kitchen waste treatment system, and a blockage handling method, which have high detection accuracy and reliability, can handle blockage faults in a short time, quickly restore production, and improve production efficiency.

[0009] A limit switch, wherein the limit switch is disposed on the overflow body and is used to output an overflow alarm signal when triggered; and

[0010] An elastic element is disposed on the limit switch. The elastic element is used to engage with the overflow cover to maintain the overflow cover in a closed state relative to the overflow port; and to trigger the limit switch when material overflows from the overflow port and pushes open the overflow cover, causing the overflow cover to separate from the elastic element.

[0011] In an optional embodiment, one of the overflow cap and the elastic member is provided with a snap-fit ​​protrusion, and the other is provided with a snap-fit ​​groove, wherein the snap-fit ​​protrusion is used to snap into the snap-fit ​​groove.

[0021] If the jamming alarm device outputs the jamming alarm signal, it controls the material conveying equipment of the kitchen waste treatment system to stop feeding and controls the cleaning device to clean the material in the extrusion shell.

[0022] If the jamming alarm device does not output the jamming alarm signal, then determine whether the limit switch outputs the overflow alarm signal;

[0023] If the limit switch outputs the overflow alarm signal, the material conveying equipment of the kitchen waste treatment system is controlled to stop feeding, and the cleaning device is controlled to clean the material in the extrusion shell.

[0024] The material conveying equipment includes the conveyor.

[0025] In an optional embodiment, the step of controlling the cleaning device to clean the material inside the extrusion housing includes:

[0026] The hydraulic cylinder of the cleaning device is controlled to retract to the initial position and remain there for a first duration;

[0027] The hydraulic cylinder is controlled to extend to a preset position and remain there for a second duration;

[0028] Repeat the steps of controlling the hydraulic cylinder of the cleaning device to retract to the initial position and stay there for a first duration, and controlling the hydraulic cylinder to extend to a preset position and stay there for a second duration, until the time for the hydraulic cylinder to move and stay reaches the first preset cleaning duration.

[0029] In an optional embodiment, before the step of controlling the hydraulic cylinder of the cleaning device to retract to the initial position and remain there for a first duration, the step of controlling the cleaning device to clean the material inside the extrusion housing further includes:

[0030] The hydraulic cylinder is controlled to stop working and remains stationary for a third duration.

[0031] In an optional embodiment, the step of controlling the cleaning device to clean the material inside the extrusion housing includes:

[0032] The main shaft motor of the cleaning device is controlled to reverse, and after a fourth duration, the main shaft motor is controlled to stop, and this is maintained for a fifth duration.

[0033] After controlling the spindle motor to rotate forward for a continuous period of six hours, the spindle motor is then stopped and maintained for a continuous period of seven hours.

[0034] Repeat the steps of controlling the main shaft motor of the cleaning device to reverse for a fourth time, then controlling the main shaft motor to stop for a fifth time, and then controlling the main shaft motor to rotate forward for a sixth time, then controlling the main shaft motor to stop for a seventh time, until the time for the main shaft motor to rotate and stop reaches the second preset cleaning time.

[0035] In an optional embodiment, before the step of controlling the main shaft motor of the cleaning device to reverse and continue for a fourth time, and then controlling the main shaft motor to stop and maintain this for a fifth time, the step of controlling the cleaning device to clean the material inside the extrusion shell further includes:

[0040] The steps of controlling the flushing water pump of the cleaning device to flush the material in the extrusion housing for a ninth time are repeated, and the steps of controlling the flushing water pump to stop flushing and maintaining it for a tenth time are repeated until the flushing and stopping time of the flushing water pump reaches a third preset cleaning time.

[0041] In an optional embodiment, before the step of controlling the flushing water pump of the cleaning device to flush the material inside the extrusion shell for a ninth duration, the step of controlling the cleaning device to clean the material inside the extrusion shell further includes:

[0042] The flushing water pump is controlled to stop working and remains in operation for eleven hours.

[0043] The beneficial effects of the embodiments of the present invention include:

[0044] The overflow alarm device includes an overflow body, an overflow cover, a limit switch, and a resilient element. The overflow body has an overflow port, and the overflow cover is movably fitted with the overflow body, used to open or close the overflow port. The limit switch is located on the overflow body and is used to output an overflow alarm signal when triggered. The resilient element is located on the limit switch and is used to engage with the overflow cover to maintain the overflow cover in a closed state relative to the overflow port; and to trigger the limit switch when material overflows from the overflow port and pushes open the overflow cover, causing the overflow cover to separate from the resilient element.

[0045] In other words, when the conveyor is operating normally, the overflow cover engages with the elastic element, closing the overflow port. At this time, the elastic element does not trigger the limit switch. However, when a blockage occurs in the food waste processing system, material overflows from the overflow port, pushing open the overflow cover and separating it from the elastic element. This triggers the limit switch, causing it to output an overflow alarm signal. Upon receiving this alarm signal, the food waste processing system will shut down all equipment and initiate subsequent blockage clearing operations on the extruder. This overflow alarm device is unaffected by external factors such as light, material condition, material layer height, or vibration, preventing misjudgments during blockages. It boasts high accuracy and reliability, enabling rapid handling of blockages and quick resumption of production, thereby improving efficiency.

[0046] The food waste treatment system includes an overflow alarm device, a conveyor, a compressor, and a blockage alarm device. The overflow material is located on the conveyor. The compressor includes a compressor housing and a cleaning device. The compressor housing is connected to the conveyor, and the cleaning device is located inside the compressor housing. The blockage alarm device is located on the compressor housing and is used to output a blockage alarm signal. When the limit switch outputs an overflow alarm signal or the blockage alarm device outputs a blockage alarm signal, the cleaning device is used to clean the material inside the compressor housing.

[0047] In other words, the clogging alarm device can directly detect clogging in the extruder. When clogging occurs, it outputs an alarm signal. Upon receiving this alarm signal, the food waste treatment system will shut down all equipment and then control the cleaning device to remove material from the extrusion shell. If the clogging alarm device is interfered with by external factors such as light, material condition, material layer height, or vibration, and fails to detect the clogging, material will accumulate at the overflow port via the conveyor. This will trigger the overflow alarm device, which in turn will shut down all equipment and control the cleaning device to remove material from the extrusion shell. Therefore, this food waste treatment system has high detection accuracy and reliability, can quickly handle clogging faults, and rapidly restore production, thereby improving production efficiency.

[0048] The method for handling food waste blockages in kitchen waste processing machines utilizes a kitchen waste processing system, which has the advantages of high detection accuracy, good reliability, ability to handle blockages in a short time, rapid resumption of production, and high production efficiency.

Detailed Implementation

[0060] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0061] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0062] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0063] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0064] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0065] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0066] As described in the background section, existing technologies for inspecting extruder blockage faults primarily rely on sensors and other detection elements to monitor the material level and screen pressure inside the conveyor or extruder to determine if blockage and overflow have occurred. However, due to the confined internal space of the conveyor or extruder, the detection elements are susceptible to interference from external factors such as light, material condition, material layer height, or vibration. This results in low accuracy and poor reliability in blockage detection, frequently leading to false alarms and failure to detect blockage and overflow. This can easily cause the food waste treatment system to shut down, impacting production efficiency.

[0067] Based on this, please refer to Figures 1-9 The embodiments of the present invention provide an overflow alarm device 100, a food waste treatment system 1000, and a method for handling machine blockage, which can effectively improve the aforementioned technical problems. Specifically, it has high detection accuracy and reliability, can handle machine blockage faults in a short time, quickly restore production, and improve production efficiency. The overflow alarm device 100, the food waste treatment system 1000, and the method for handling machine blockage will be described in detail below.

[0068] Please refer to Figure 1 , Figure 1 This is a structural diagram of the kitchen waste treatment system 1000 provided in this embodiment, combined with... Figure 1 The food waste treatment system 1000 includes an overflow alarm device 100, a conveyor 200, a compressor 300, and a blockage alarm device (not shown in the figure). The overflow alarm device 100 is located on the conveyor 200. The conveyor 200 is connected to the compressor 300 and is used to transport materials to the compressor 300. The compressor 300 performs subsequent processing such as compression on the materials. The blockage alarm device is located on the compressor 300.

[0069] It should be noted that when the extruder 300 experiences a blockage fault, the blockage alarm device can issue a blockage alarm signal to remind the user; however, if the blockage alarm device is interfered with and makes a false judgment, and fails to detect the blockage fault, the overflow alarm device 100 will issue an overflow alarm signal to remind the user.

[0070] For details, please refer to Figure 2 and Figure 3 , Figure 2 This is a schematic diagram showing the off state of the overflow alarm device 100 provided in this embodiment. Figure 3 This is a schematic diagram showing the open state of the overflow alarm device 100 provided in this embodiment.

[0071] Combination Figure 2 and Figure 3The overflow alarm device 100 includes an overflow body 10, an overflow cover 20, a limit switch 30, and a resilient element 40. The overflow body 10 has an overflow port 11, and the overflow cover 20 is movably fitted with the overflow body 10, used to open or close the overflow port 11. The limit switch 30 is disposed on the overflow body 10 and is used to output an overflow alarm signal when triggered. The resilient element 40 is disposed on the limit switch 30 and is used to engage with the overflow cover 20 to maintain the overflow cover 20 in a closed state relative to the overflow port 11; and to trigger the limit switch 30 when material 001 overflows from the overflow port 11 and pushes open the overflow cover 20, causing the overflow cover 20 to separate from the resilient element 40.

[0072] In other words, when the conveyor 200 is operating normally, the overflow cover 20 is engaged with the elastic element 40, closing the overflow port 11. At this time, the elastic element 40 will not trigger the limit switch 30. However, when the food waste treatment system 1000 experiences a blockage, and material 001 overflows from the overflow port 11, the material 001 will push open the overflow cover 20, separating it from the elastic element 40. At this point, the elastic element 40 will trigger the limit switch 30, causing it to output an overflow alarm signal. Upon receiving this overflow alarm signal, the food waste treatment system 1000 will control all equipment to stop and perform subsequent blockage clearing operations on the extruder 300. It is easy to understand that this overflow alarm device 100 is not affected by external factors such as light, material condition, material layer height, or vibration, avoiding misjudgments during blockages. It has high detection accuracy and reliability, can quickly resolve blockages, and rapidly restore production, thereby improving production efficiency.

[0073] It should be noted that in this embodiment, the elastic element 40 is specifically a contact spring rod. One end of the overflow cover 20 is rotatably connected to the overflow body 10, and the other end of the overflow cover 20 is used to engage with the contact spring rod. When the overflow cover 20 is engaged with the contact spring rod, the contact spring rod will be compressed. At this time, it can be understood that the circuit of the limit switch 30 will be disconnected. When the material 001 pushes the overflow cover 20 open, one end of the overflow cover 20 will rotate relative to the overflow body 10, thereby causing the other end of the overflow cover 20 to separate from the contact spring rod. The contact spring rod will then extend and return to its original position. At this time, the limit switch 30 can be triggered to energize it and issue an overflow alarm signal.

[0074] Of course, in other embodiments, the elastic element 40 can also be a spring sheet, rubber sleeve or other elastic structure, as long as it can cooperate with the limit switch 30 to achieve circuit breaking or power supply.

[0075] Further, please refer to Figure 4 , Figure 4 This is a structural schematic diagram of the extruder 300 provided in this embodiment, combined with... Figures 1-4 Specifically, the overflow body 10 is installed on the conveyor 200, and the extruder 300 includes an extrusion shell 301 and a cleaning device 302. The extrusion shell 301 is connected to the conveyor 200, and the cleaning device 302 is installed inside the extrusion shell 301. A jamming alarm device is installed in the extrusion shell 301 and is used to output a jamming alarm signal. When the limit switch 30 outputs an overflow alarm signal or when the jamming alarm device outputs a jamming alarm signal, the cleaning device 302 is used to clean the material inside the extrusion shell 301.

[0076] In other words, the blockage alarm device can directly detect the blockage situation of the extruder 300. When the extruder 300 experiences a blockage fault, it outputs a blockage alarm signal. Upon receiving this alarm signal, the food waste treatment system 1000 will control all equipment to stop and then control the cleaning device 302 to clean the material inside the extrusion shell 301. If the blockage alarm device is interfered with by external factors such as light, material state, material layer height, or vibration, and fails to detect the blockage fault, the material 001 will accumulate at the overflow port 11 via the conveyor 200. The overflow alarm device 100 will then be triggered, issuing an overflow alarm signal. This again triggers the food waste treatment system 1000 to control all equipment to stop and then controls the cleaning device 302 to clean the material inside the extrusion shell 301. Therefore, the food waste treatment system 1000 has high detection accuracy and reliability, can handle blockage faults quickly, and rapidly restore production, thereby improving production efficiency.

[0077] It should be noted that the overflow body 10 is specifically connected to the outer shell of the conveyor 200. The overflow body 10 and the outer shell can be integrally formed, or they can be connected and fixed by welding, bolting or riveting.

[0078] Please refer to Figure 5 , Figure 5 This is an assembly diagram of the limit switch 30 and the elastic element 40 provided in this embodiment, combined with... Figure 2 , Figure 3 and Figure 5 One of the overflow cover 20 and the elastic member 40 is provided with a snap-fit ​​protrusion 21, and the other is provided with a snap-fit ​​groove 41. The snap-fit ​​protrusion 21 is used to snap-fit ​​with the snap-fit ​​groove 41.

[0079] Specifically, in this embodiment, the overflow cover 20 is provided with a snap-fit ​​protrusion 21, and the elastic member 40 is provided with a snap-fit ​​groove 41; of course, in other embodiments, the overflow cover 20 may be provided with a snap-fit ​​groove 41, and the elastic member 40 may be provided with a snap-fit ​​protrusion 21. As long as the snap-fit ​​between the two can be achieved, and the material 001 can separate the two from the snap-fit ​​state in the event of overflow, it is acceptable.

[0080] Combination Figure 2 and Figure 3 To ensure the stability of the overflow cover 20 when it is not supported by material 001, in this embodiment, the overflow alarm device 100 also includes a counterweight 50, which is disposed at the end of the overflow cover 20 near the elastic member 40. By setting the counterweight 50, it can be ensured that the overflow cover 20 and the elastic member 40 are stably engaged when no overflow occurs, thereby ensuring that the overflow cover 20 closes the overflow port 11 and prevents material 001 from overflowing from the overflow port 11 when the conveyor 200 is working normally. Furthermore, due to the combined weight of the overflow cover 20 and the counterweight 50, it is difficult to separate the overflow cover 20 from the elastic member 40 unless a large external force is applied. During normal operation of the equipment, ordinary vibrations will not cause the overflow cover 20 to shift, thereby reducing the possibility of false judgment by the overflow alarm device 100 and further improving the detection accuracy and reliability.

[0081] It should be noted that the counterweight 50 can be made from locally available materials. For example, it can be made from leftover steel plates, bolts, or screws from the production process and placed on the overflow cover 20, thereby saving production costs.

[0082] Furthermore, to facilitate the installation of the limit switch 30 and improve its operational stability, the overflow alarm device 100 also includes a mounting bracket 60, which is disposed on the overflow body 10, and the limit switch 30 is disposed on the mounting bracket 60. Combined with... Figures 1-3 The mounting bracket 60 can also be connected to both the overflow body 10 and the housing of the conveyor 200, thereby further improving the connection stability of the mounting bracket 60.

[0083] It should be noted that in this embodiment, the mounting bracket 60 is L-shaped, which helps to reduce the vibration of the limit switch 30. Of course, in other embodiments, the mounting bracket 60 can also be S-shaped, C-shaped, or V-shaped, etc.

[0084] Please continue to combine Figure 4 Specifically, the material cleaning device 302 includes a hydraulic cylinder 3021 and a screen 3022. Both the hydraulic cylinder 3021 and the screen 3022 are disposed within the extrusion housing 301. The hydraulic cylinder 3021 is connected to the screen 3022 and is used to drive the screen 3022 to move relative to the extrusion housing 301. During the material cleaning operation, by controlling the hydraulic cylinder 3021 to move forward or backward, the screen 3022 can be moved, thereby increasing the volume of the extrusion area within the extrusion housing 301, reducing the extrusion pressure, and facilitating the removal of material blockage.

[0085] Furthermore, the cleaning device 302 also includes a main shaft motor 3023, which is disposed inside the extrusion housing 301. During the cleaning operation, by controlling the main shaft motor 3023 to rotate forward or reverse, it is possible to facilitate the return of material, thereby making it easier to clean up any blockages.

[0086] Furthermore, the cleaning device 302 also includes a flushing pipe 3024 and a flushing water pump 3025. The flushing pipe 3024 is connected to both the flushing water pump 3025 and the extrusion housing 301. The flushing water pump 3025 is used to flush the material inside the extrusion housing 301 through the flushing pipe 3024. In other words, during the cleaning operation, by controlling the flushing water pump 3025, the flushing pipe 3024 is used to flush and clean the material blockage inside the extrusion housing 301. At the same time, it can work in conjunction with the hydraulic cylinder 3021 and the screen 3022 to facilitate the dispersing of the material cake layer under the action of the flushing water.

[0087] It should be noted that during the material cleaning operation, the hydraulic cylinder 3021, the main shaft motor 3023, and the flushing water pump 3025 can be controlled simultaneously. Depending on the actual situation, the blockage can be handled in coordination among the three, thereby further improving the cleaning effect and efficiency. This ensures that the blockage can be dealt with in a short time, enabling rapid resumption of production and further improving production efficiency.

[0088] Please refer to Figure 6 , Figure 6 This is a flowchart of the food waste blockage treatment method provided in this embodiment, combined with... Figure 6 The method for handling food waste blockages utilizes a food waste treatment system 1000, which includes:

[0089] Step S10: Determine whether the jamming alarm device outputs a jamming alarm signal;

[0090] Step S20: If the jamming alarm device does not output a jamming alarm signal, determine whether the limit switch 30 outputs an overflow alarm signal;

[0091] Step S30: If the jamming alarm device outputs a jamming alarm signal, or if the limit switch 30 outputs an overflow alarm signal, then control the material conveying equipment of the kitchen waste treatment system 1000 to stop feeding.

[0092] Step S40: Control the cleaning device 302 to clean the material inside the extrusion shell 301.

[0093] Understandably, the system will only continue to check whether the overflow alarm device 100 issues an overflow alarm signal if the jamming alarm device malfunctions and fails to detect a jamming fault in the extruder 300. That is, during the waste processing process, as long as either the jamming alarm device 100 or the overflow alarm device 100 issues an overflow alarm signal, the food waste processing system 1000 can immediately control the material conveying equipment to stop feeding and then proceed with the subsequent cleaning process. If neither of them issues an alarm signal, it indicates that the extruder 300 is working normally and no jamming fault has occurred.

[0094] Therefore, this method for handling food waste blockages also has the advantages of high detection accuracy and high reliability. It can handle blockages in a short time and quickly restore production, thereby improving production efficiency.

[0095] It should be noted that the material conveying equipment mentioned in step S30 above includes conveyor 200. That is, after a blockage occurs, it is necessary to first stop conveyor 200 from continuing to convey materials, and then use cleaning device 302 to clean the materials inside the extrusion shell 301. Of course, it is easy for those skilled in the art to know that the material conveying equipment of the kitchen waste treatment system 1000 may also include garbage trucks, sorting and screening devices, bag breakers or crushers, etc. When a blockage occurs, it is necessary to control each device of the material conveying equipment to stop feeding in sequence, so as to facilitate subsequent cleaning operations.

[0096] In addition, it should be noted that the kitchen waste treatment system 1000 also includes a controller (not shown in the figure). The controller is used to acquire the jamming alarm signal and the overflow alarm signal, and to control the start and stop of the material conveying equipment and the extruder 300, that is, to control the operation of the garbage truck, the sorting and screening device, the bag breaking machine, the crusher, the conveyor 200 and the extruder 300.

[0097] In this embodiment, the cleaning device 302 includes a hydraulic cylinder 3021, a spindle motor 3023, and a flushing water pump 3025. Therefore, the controller is used to control the hydraulic cylinder 3021, the spindle motor 3023, and the flushing water pump 3025 to perform corresponding cleaning operations.

[0098] For details, please refer to Figure 7 , Figure 7 for Figure 6 The flowchart of the first seed step in step S40, combined with Figure 6 and Figure 7 Step S40 includes:

[0099] Sub-step S42a: Control the hydraulic cylinder 3021 to retract to the initial position and maintain it for a first duration;

[0100] Sub-step S43a: Control the hydraulic cylinder 3021 to extend to the preset position and maintain it for a second duration;

[0101] Sub-step S44a: Repeat steps S42a and S43a until the time for the hydraulic cylinder 3021 to move and stay reaches the first preset cleaning time.

[0102] In other words, during the retraction or extension of the hydraulic cylinder 3021, the screen 3022 can be moved, thereby increasing the volume of the extrusion area inside the extrusion housing 301, reducing the extrusion pressure, and facilitating the removal of material blockage.

[0103] It should be noted that both the initial position and the preset position can be adjusted. For example, the initial position can be the position where the hydraulic cylinder 3021 retracts to its shortest length, and the preset position can be the position where the hydraulic cylinder 3021 extends to its longest length.

[0104] Similarly, the specific values ​​of the first and second durations can be adjusted according to the actual situation. The first and second durations can be the same or different. For example, the first duration can be set to 30 seconds, and the second duration can also be set to 30 seconds. That is, the hydraulic cylinder 3021 retracts and stays for 30 seconds before extending, and then stays for another 30 seconds after extending to the preset position. This retraction and extension action of the hydraulic cylinder 3021 can be understood as forward or backward movement. In this way, the forward or backward movement of the hydraulic cylinder 3021 is repeated until the time for controlling the action of the hydraulic cylinder 3021 reaches the first preset cleaning duration, and then the mode of controlling the hydraulic cylinder 3021 to clean the material is exited.

[0105] It is easy to understand that by controlling the hydraulic cylinder 3021 to perform this intermittent action, it can be ensured that the hydraulic cylinder 3021 cannot immediately extend after retracting, or cannot immediately retract after extending, and a forced rest is required in the middle. This can protect the extruder 300 and prevent damage caused by excessive torque of the hydraulic cylinder 3021. At the same time, during this pause time, it can also wait for the cleaning operation of other components of the cleaning device 302 to cooperate and improve the cleaning effect.

[0106] It should be noted that if the hydraulic cylinder 3021 fails to move and becomes completely blocked during the material clearing operation, the material clearing operation controlled by the material clearing device 302 should be stopped and switched to manual adjustment. The material clearing operation can be continued after the hydraulic cylinder 3021 can move.

[0107] Please continue to combine Figure 7 Furthermore, before sub-step S42a, step S40 also includes:

[0108] Sub-step S41a: Control the hydraulic cylinder 3021 to stop working and maintain it for a third duration.

[0109] It should be noted that this third duration can also be adjusted according to the actual cleaning situation. Since the hydraulic cylinder 3021 is also moving normally during the normal operation of the extruder 300, if a blockage occurs, the controller will control the cleaning device to perform the cleaning action. At this time, by first stopping the hydraulic cylinder 3021 and maintaining this for a certain period, an intermittent setting can be achieved. This protects the extruder 300 from damage caused by excessive torque of the hydraulic cylinder 3021, and also allows for the waiting for the cleaning operations of other components of the cleaning device 302 to coordinate, thereby further improving the cleaning effect.

[0110] Please refer to Figure 8 , Figure 8 for Figure 6 The flowchart of the second seed step in step S40, combined with Figure 6 and Figure 8 Step S40 includes:

[0111] Sub-step S42b: Control the spindle motor 3023 to reverse, continue for the fourth time, then control the spindle motor 3023 to stop, and maintain for the fifth time;

[0112] Sub-step S43b: Control the spindle motor 3023 to rotate forward for six hours, then control the spindle motor 3023 to stop and maintain this for seven hours.

[0113] Sub-step S44b: Repeat steps S42b and S43b until the rotation and shutdown time of the spindle motor 3023 reaches the second preset cleaning time.

[0114] In other words, during the material clearing operation, controlling the main shaft motor 3023 to rotate forward or reverse facilitates material return, thereby making it easier to clear the blockage.

[0115] It should be noted that the fourth, fifth, sixth, and seventh time durations can all be adjusted according to actual conditions. These times can be the same or different. For example, the fourth and sixth time durations can be set to 30 seconds, while the fifth and seventh time durations can be set to 15 seconds. That is, the forward and reverse rotation of the main spindle motor 3023 can be set to the same duration, with the corresponding stop times being the same. In other words, the main spindle motor 3023 reverses for 30 seconds, then stops for 15 seconds, then rotates forward for 30 seconds, and then stops again for 15 seconds. This forward or reverse rotation and stop operation of the main spindle motor 3023 is repeated until the overall operation time of the main spindle motor 3023 reaches the second preset cleaning duration, at which point the mode of controlling the main spindle motor 3023 for material cleaning is exited.

[0116] Understandably, by controlling the main shaft motor 3023 to perform this intermittent action, it can be ensured that the main shaft motor 3023 cannot immediately reverse after rotating forward, or cannot immediately rotate forward after reversing, and a forced rest is required in between. This can protect the extruder 300 and prevent the main shaft motor 3023 from burning out due to frequent forward and reverse rotation or excessive instantaneous current. At the same time, this pause time can also wait for the cleaning operation of other components of the cleaning device 302 to cooperate and improve the cleaning effect.

[0117] Please continue to combine Figure 8 Furthermore, before sub-step S42b, step S40 also includes:

[0118] Sub-step S41b: Control the spindle motor 3023 to stop and maintain for the eighth duration.

[0119] It should be noted that this eighth duration can also be adjusted according to the actual cleaning situation. Since the main shaft motor 3023 is also rotating normally during the normal operation of the extruder 300, if a blockage occurs, the controller will control the cleaning device to perform the cleaning action. At this time, by first stopping the main shaft motor 3023 and maintaining this for a certain period, an intermittent setting can be achieved, thereby protecting the extruder 300 and preventing the main shaft motor 3023 from burning out due to frequent forward and reverse rotation or excessive instantaneous current. It also allows for the waiting of the cleaning operations of other components of the cleaning device 302, enabling coordinated operation and further improving the cleaning effect.

[0120] Please refer to Figure 9 , Figure 9 for Figure 6 The flowchart of the third seed step in step S40, combined with... Figure 6 and Figure 9 Step S40 includes:

[0121] Sub-step S42c: Control the flushing water pump 3025 to flush the material inside the extrusion shell 301 for a duration of nine hours;

[0122] Sub-step S43c: Control the flushing water pump 3025 to stop flushing and maintain it for ten hours;

[0123] Sub-step S44c: Repeat steps S42c and S43c until the flushing time of the flushing pump 3025 reaches the third preset cleaning time.

[0124] In other words, during the material cleaning operation, the flushing water pump 3025 is controlled to flush and clean the blockage in the extrusion shell 301 through the flushing pipeline 3024; at the same time, it can work together with the hydraulic cylinder 3021 and the screen 3022 to facilitate the dispersal of the material cake layer under the action of the flushing water.

[0125] It should be noted that the ninth and tenth durations can be adjusted according to the actual situation. The two durations can be the same or different. For example, the ninth duration can be set to 30 seconds and the tenth duration can be set to 180 seconds. That is, after the flushing water pump 3025 flushes for 30 seconds, the flushing stops and is maintained for 180 seconds. The flushing and stopping operation of the flushing water pump 3025 is repeated until the total operation time of the flushing water pump 3025 reaches the third preset cleaning duration, and then the mode of controlling the flushing water pump 3025 to clean the material is exited.

[0126] It is understandable that by controlling the flushing water pump 3025 to perform this intermittent flushing action, it is possible to wait for the other components of the cleaning device 302 to perform cleaning operations during the flushing stop process. That is, in this embodiment, it is possible to wait for the hydraulic cylinder 3021 to move forward or backward, and for the main shaft motor 3023 to rotate forward or backward. After the material has been cleaned to a certain extent through the above operations, the flushing water pump 3025 is turned on to flush again. In this way, the cleaning effect is improved through mutual coordination.

[0127] Please continue to combine Figure 9 Furthermore, before sub-step S42c, step S40 also includes:

[0128] Sub-step S41c: Control the flushing water pump 3025 to stop working and maintain it for eleven hours.

[0129] It should be noted that this eleventh duration can also be adjusted according to the actual cleaning situation. When the machine malfunctions and the material cleaning device 302 is cleaning the material, stopping the flushing water pump 3025 for a certain period of time can ensure coordination with other components of the material cleaning device 302. That is, in this embodiment, waiting for the hydraulic cylinder 3021 to move forward or backward, and the main shaft motor 3023 to rotate forward or backward, and after the material has been cleaned to a certain extent, the flushing water pump 3025 is turned on for rinsing. This can further improve the cleaning effect.

[0130] In addition, it should be noted that the first, second, ... eleventh durations mentioned above are set as development parameters and can be adjusted according to the actual cleaning situation. They are highly adaptable and versatile, and can be combined with various waste treatment conditions and factors to comprehensively coordinate and set the cleaning time, further improving the cleaning effect and production efficiency. Furthermore, the flushing water volume can also be controlled as needed, which can save resources and reduce costs.

[0131] According to the above description, after the material is cleaned up and the blockage is resolved, the elastic element 40 needs to be manually reset. That is, the overflow cover 20 is snapped into the elastic element 40 to close the overflow port 11 and disconnect the limit switch 30. This setting can prevent strong impacts or collisions from compressing or popping the elastic element 40, thereby ensuring the service life of the elastic element 40 and the limit switch 30.

[0132] It should be noted that, from a safety perspective, the kitchen waste treatment system 1000 provided in this embodiment, except for the elastic element 40 and the overflow cover 20 which require manual reset, is fully automated in terms of jamming alarm, overflow alarm, and subsequent cleaning operations, resulting in high production efficiency. This avoids the frequent misjudgments by detection elements in existing technologies, such as misjudging localized material buildup inside enclosed conveyor equipment as blockage, leading to frequent production line starts and stops. This not only fails to accurately detect jamming faults but also significantly impacts production efficiency. Furthermore, it saves considerable manpower and resources, allowing for early intervention when jamming faults occur, reducing the cleaning burden. The system boasts high reliability and improved production efficiency.

[0133] In summary, embodiments of the present invention provide an overflow alarm device 100, a kitchen waste treatment system 1000, and a blockage treatment method. The overflow alarm device 100 includes an overflow body 10, an overflow cover 20, a limit switch 30, and an elastic element 40. The overflow body 10 has an overflow port 11, and the overflow cover 20 is movably engaged with the overflow body 10, used to open or close the overflow port 11. The limit switch 30 is disposed on the overflow body 10 and is used to output an overflow alarm signal when triggered. The elastic element 40 is disposed on the limit switch 30 and is used to engage with the overflow cover 20 to maintain the overflow cover 20 in a closed state relative to the overflow port 11; and to trigger the limit switch 30 when material 001 overflows from the overflow port 11 and pushes open the overflow cover 20, causing the overflow cover 20 to separate from the elastic element 40.

[0134] When the conveyor 200 is operating normally, the overflow cover 20 is engaged with the elastic element 40, closing the overflow port 11. At this time, the elastic element 40 will not trigger the limit switch 30. However, when the food waste treatment system 1000 experiences a blockage, and material 001 overflows from the overflow port 11, the material 001 will push open the overflow cover 20, separating it from the elastic element 40. At this time, the elastic element 40 will trigger the limit switch 30, causing it to output an overflow alarm signal. Upon receiving this overflow alarm signal, the food waste treatment system 1000 will control all equipment to stop and perform subsequent blockage clearing operations on the extruder 300. It is easy to understand that this overflow alarm device 100 is not affected by external factors such as light, material condition, material layer height, or vibration, avoiding misjudgments during blockages. It has high detection accuracy and reliability, and can quickly handle blockages and restore production, thereby improving production efficiency.

[0135] The kitchen waste treatment system 1000 includes an overflow alarm device 100, a conveyor 200, a compressor 300, and a blockage alarm device. The overflow body 10 is disposed on the conveyor 200. The compressor 300 includes a compressor housing 301 and a cleaning device 302. The compressor housing 301 is connected to the conveyor 200, and the cleaning device 302 is disposed inside the compressor housing 301. The blockage alarm device is disposed on the compressor housing 301 and is used to output a blockage alarm signal. When the limit switch 30 outputs an overflow alarm signal or when the blockage alarm device outputs a blockage alarm signal, the cleaning device 302 is used to clean the material inside the compressor housing 301.

[0136] The clogging alarm device can directly detect clogging in the extruder 300. When clogging occurs, it outputs an alarm signal. Upon receiving this alarm signal, the food waste treatment system 1000 will stop all equipment and then control the cleaning device 302 to clean the material inside the extrusion shell 301. If the clogging alarm device is interfered with by external factors such as light, material condition, material layer height, or vibration, and fails to detect the clogging, material 001 will accumulate at the overflow port 11 via the conveyor 200. The overflow alarm device 100 will then be triggered, issuing an overflow alarm signal. This again triggers the food waste treatment system 1000 to stop all equipment and control the cleaning device 302 to clean the material inside the extrusion shell 301. Therefore, the food waste treatment system 1000 has high detection accuracy and reliability, can handle clogging in a short time, and quickly restore production, thereby improving production efficiency.

[0137] The method for handling food waste blockages is implemented using the 1000 food waste treatment system, which has the advantages of high detection accuracy, good reliability, ability to handle blockages in a short time, rapid resumption of production, and high production efficiency.

[0138] The above description is merely a specific embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
