Description

Technical Field

[0001] The present invention relates to the technical field of kitchen waste treatment, and in particular to an overflow alarm device, a kitchen waste treatment system and a machine blockage treatment method. Background Art

[0002] In the process of kitchen waste treatment, the conveyor, as the upstream equipment of the extruder, plays an important role in conveying kitchen waste to the feed port of the extruder. When the extruder fails (i.e., "blockage"), if the conveyor continues to feed, the material will gradually fill the space between the conveyor and the feed port of the extruder, causing the material to gradually accumulate and the difficulty of cleaning to gradually increase. For the inspection of extruder blockage failure, the existing technology mainly uses sensors and other detection elements to detect the material level inside the conveyor or extruder and the pressure on the screen, so as to determine whether the machine is blocked and overflowing.

[0003] However, due to the narrow internal space of the conveyor or extruder, the detection elements will be disturbed by external factors such as light, material status, material layer height or vibration, resulting in low accuracy and poor reliability of machine jam detection. The detection elements often make misjudgments and are unable to detect that machine jams and overflows have occurred, which can easily cause the food waste treatment system to shut down and affect production efficiency.

[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 travel switch and an elastic member. The overflow body has an overflow port, and the overflow cover is movably matched with the overflow body, and the overflow cover is used to open or close the overflow port. The travel switch is arranged on the overflow body, and is used to output an overflow alarm signal when triggered. The elastic member is arranged on the travel switch, and the elastic member is used to engage with the overflow cover to keep the overflow cover closed to the overflow port; and is used to trigger the travel switch when the material overflows from the overflow port and pushes open the overflow cover, so that the overflow cover is separated from the elastic member.

[0045] That is to say, when the conveyor is working normally, the overflow cover is engaged with the elastic part, so that the overflow port is closed, and the elastic part will not trigger the travel switch at this time; and when the kitchen waste treatment system has a machine jam failure and the material overflows from the overflow port, the material will push open the overflow cover, so that the overflow cover is separated from the elastic part, and the elastic part will trigger the travel switch at this time, so that the travel switch outputs an overflow alarm signal.

It is easy to understand that the overflow alarm device will not be disturbed by external factors such as light, material state, material layer height or vibration, and can avoid misjudgment when a machine jam occurs. It has high detection accuracy and good reliability, and can handle machine jams in a short time and quickly resume production, thereby improving production efficiency.

[0047] That is to say, the machine jam alarm device can directly detect the jam situation of the extruder. When the extruder is jammed, it outputs a machine jam alarm signal. After receiving the machine jam alarm signal, the kitchen waste treatment system will control each device to shut down, and then control the cleaning device to clean the material in the extrusion shell. When the machine jam alarm device is disturbed by external factors such as light, material status, material layer height or vibration, and misjudges and fails to detect the jam that has occurred, the material will accumulate at the overflow port through the conveyor, and then the overflow alarm device will continue to be triggered, thereby issuing an overflow alarm signal, and then the kitchen waste treatment system will also control each device to shut down, and then control the cleaning device to clean the material in the extrusion shell. Therefore, the kitchen waste treatment system has high detection accuracy and good reliability, and can handle machine jams in a short time and quickly resume production, thereby improving production efficiency.

[0048] The method for handling kitchen waste jam machine is implemented by utilizing a kitchen waste treatment system, which also has the beneficial effects of high detection accuracy, good reliability, being able to handle machine jam failures in a short time, quickly resuming production, and having high production efficiency.

DETAILED DESCRIPTION

[0060] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0061] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0063] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0064] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0065] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0066] As described in the background technology, for the inspection of the jam failure of the extruder, the existing technology mainly uses sensors and other detection elements to detect the material level inside the conveyor or extruder and the pressure on the screen, so as to determine whether the machine is jammed or overflowing. However, due to the narrow internal space of the conveyor or extruder, the detection element will be disturbed by external factors such as light, material state, material layer height or vibration, resulting in low accuracy and poor reliability of jam detection, which makes the detection element often misjudge and fail to detect that the jam has occurred, which easily leads to the shutdown of the kitchen waste treatment system and affects production efficiency.

[0067] Based on this, please refer to Figure 1-Figure 9 The embodiment of the present invention provides an overflow alarm device 100, a kitchen waste treatment system 1000 and a machine jam treatment method, which can effectively improve the above-mentioned technical problems, that is, it has high detection accuracy and good reliability, can handle machine jam failures in a short time, quickly resume production, and improve production efficiency. The overflow alarm device 100, the kitchen waste treatment system 1000 and the machine jam treatment method will be described in detail below.

[0068] Please refer to Figure 1 , Figure 1 The structural diagram of the kitchen waste treatment system 1000 provided in this embodiment is combined with Figure 1 The kitchen waste treatment system 1000 includes an overflow alarm device 100, a conveyor 200, an extruder 300, and a machine jam alarm device (not shown). The overflow alarm device 100 is arranged on the conveyor 200. The conveyor 200 is connected to the extruder 300 to convey the material to the extruder 300. The extruder 300 performs subsequent compression and other processing on the material, and the machine jam alarm device is arranged on the extruder 300.

[0069] It should be noted that when the extruder 300 is jammed, the jam alarm device can send out a jam alarm signal to remind; and when the jam alarm device is interfered with and misjudged and cannot detect that a jam has occurred, the overflow alarm device 100 will send out an overflow alarm signal to remind.

[0070] Specifically, please refer to Figure 2 and Figure 3 , Figure 2 A schematic diagram of the closed state of the overflow alarm device 100 provided in this embodiment, Figure 3 This is a schematic diagram of 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 travel switch 30 and an elastic member 40. The overflow body 10 has an overflow port 11, and the overflow cover 20 is movably matched with the overflow body 10, and the overflow cover 20 is used to open or close the overflow port 11. The travel switch 30 is arranged on the overflow body 10, and is used to output an overflow alarm signal when triggered. The elastic member 40 is arranged on the travel switch 30, and the elastic member 40 is used to engage with the overflow cover 20 to keep the overflow cover 20 closed to the overflow port 11; and is used to trigger the travel switch 30 when the material 001 overflows from the overflow port 11 and pushes open the overflow cover 20, so that the overflow cover 20 is separated from the elastic member 40.

[0072] That is to say, when the conveyor 200 is working normally, the overflow cover 20 is engaged with the elastic member 40, so that the overflow port 11 is closed, and the elastic member 40 will not trigger the travel switch 30 at this time; and when the kitchen waste treatment system 1000 has a machine jam failure, and the material 001 overflows from the overflow port 11, the material 001 will push open the overflow cover 20, so that the overflow cover 20 is separated from the elastic member 40, and the elastic member 40 will trigger the travel switch 30, so that the travel switch 30 outputs an overflow alarm signal. In this way, after receiving the overflow alarm signal, the kitchen waste treatment system 1000 will control each device to stop, and perform the subsequent machine jam cleaning operation of the extruder 300. It is easy to understand that the overflow alarm device 100 will not be disturbed by external factors such as light, material state, material layer height or vibration, and can avoid misjudgment when a machine jam occurs. It has high detection accuracy and good reliability, and can handle the machine jam failure in a short time and quickly resume production, thereby improving production efficiency.

[0073] It should be noted that, in the present embodiment, the elastic member 40 is specifically a contact spring rod, one end of the overflow cover 20 is specifically 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, and it can be understood that the circuit of the travel switch 30 will be disconnected at this time; and 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, so that the other end of the overflow cover 20 is separated from the contact spring rod, and the contact spring rod will stretch and return to its original position, at which time the travel switch 30 can be triggered to be energized and send out an overflow alarm signal.

[0074] Of course, in other embodiments, the elastic member 40 may also be other elastic structures such as springs, rubber sleeves, etc., as long as they can cooperate with the travel switch 30 to achieve circuit breaking or power-on.

[0075] For further information, please refer to Figure 4 , Figure 4 The schematic diagram of the structure of the extruder 300 provided in this embodiment, combined with Figure 1-Figure 4 Specifically, the overflow body 10 is arranged on the conveyor 200, 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 arranged in the extrusion shell 301; the machine blockage alarm device is arranged in the extrusion shell 301, and is used to output a machine blockage alarm signal; wherein, when the travel switch 30 outputs an overflow alarm signal or when the machine blockage alarm device outputs a machine blockage alarm signal, the cleaning device 302 is used to clean the material in the extrusion shell 301.

[0076] That is to say, the jam alarm device can directly detect the jam situation of the extruder 300. When the extruder 300 is jammed, it outputs a jam alarm signal. After receiving the jam alarm signal, the kitchen waste treatment system 1000 will control each device to stop, and then control the cleaning device 302 to clean the material in the extrusion shell 301. When the jam alarm device is interfered by external factors such as light, material state, material layer height or vibration, and misjudgments and fails to detect the jam that has occurred, the material 001 will accumulate at the overflow port 11 through the conveyor 200, and then the overflow alarm device 100 will continue to be triggered, thereby issuing an overflow alarm signal, and then the kitchen waste treatment system 1000 will also control each device to stop, and then control the cleaning device 302 to clean the material in the extrusion shell 301. Therefore, the kitchen waste treatment system 1000 has high detection accuracy and good reliability, and can handle jam failures in a short time and quickly resume 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, and of course can also be connected and fixed by welding, bolting or riveting.

[0078] Please refer to Figure 5 , Figure 5 The schematic diagram of the assembly of the travel switch 30 and the elastic member 40 provided in this embodiment is 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-fitting protrusion 21 , and the other is provided with a snap-fitting groove 41 , and the snap-fitting protrusion 21 is used for snap-fitting with the snap-fitting groove 41 .

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

[0080] Combination Figure 2 and Figure 3 In order to ensure the stability of the overflow cover 20 when it is not resisted by the material 001, in this embodiment, the overflow alarm device 100 further includes a counterweight 50, which is arranged at one end of the overflow cover 20 close to the elastic member 40. By providing 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 preventing the material 001 from overflowing from the overflow port 11 when the conveyor 200 is working normally. In addition, due to the combination of the gravity of the overflow cover 20 and the counterweight 50, it is difficult to separate the overflow cover 20 from the elastic member 40 unless there is a large external force. During the normal operation of the equipment, general vibration will not cause the overflow cover 20 to shift, thereby reducing the possibility of misjudgment of 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 local materials. For example, by utilizing the steel plates, bolts, screws and other accessories left over from the production process, they can be set on the overflow cover 20, thereby saving production costs.

[0082] Furthermore, in order to facilitate the installation of the travel switch 30 and improve its working stability, the overflow alarm device 100 further includes a mounting bracket 60, which is disposed on the overflow body 10, and the travel switch 30 is disposed on the mounting bracket 60. Figure 1-Figure 3 The mounting bracket 60 can also be connected to the overflow body 10 and the outer shell of the conveyor 200 at the same time, thereby further improving the connection stability of the mounting bracket 60.

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

[0084] Please continue to combine Figure 4 Specifically, the cleaning device 302 includes a hydraulic cylinder 3021 and a screen 3022, both of which are arranged in 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. When performing the cleaning operation, the screen 3022 can be driven to move by controlling the hydraulic cylinder 3021 to move forward or backward, thereby increasing the extrusion area volume in the extrusion housing 301, reducing the extrusion force, and facilitating the cleaning of the plugged material.

[0085] Furthermore, the cleaning device 302 further includes a spindle motor 3023, which is disposed in the extrusion housing 301. When performing the cleaning operation, the spindle motor 3023 can be controlled to rotate forward or reversely to facilitate the return of materials, thereby facilitating the cleaning of the jammed materials.

[0086] Furthermore, the material cleaning device 302 further includes a flushing pipeline 3024 and a flushing water pump 3025. The flushing pipeline 3024 is connected to the flushing water pump 3025 and the extrusion housing 301 at the same time. The flushing water pump 3025 is used to flush the material in the extrusion housing 301 through the flushing pipeline 3024. That is, when performing the material cleaning operation, the flushing water pump 3025 is controlled to flush and clean the plugged material in the extrusion housing 301 through the flushing pipeline 3024; at the same time, it can cooperate with the hydraulic cylinder 3021 and the screen 3022 to facilitate the breaking of the material cake layer under the action of the flushing water.

[0087] It should be noted that when performing the material cleaning operation, the hydraulic cylinder 3021, the spindle motor 3023 and the flushing water pump 3025 can be controlled at the same time. According to the actual situation, the blockage is handled with the coordinated cooperation of the three, thereby further improving the cleaning effect and efficiency, and then ensuring that the machine blockage failure is handled in a short time, achieving rapid resumption of production, and further improving production efficiency.

[0088] Please refer to Figure 6 , Figure 6 The flowchart of the method for processing kitchen waste plugging machine provided in this embodiment is combined with Figure 6 The method for treating kitchen waste is implemented by using a kitchen waste treatment system 1000, which includes:

[0089] Step S10: determining whether the machine jam alarm device outputs a machine jam alarm signal;

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

[0091] Step S30: If the machine jam alarm device outputs a machine jam alarm signal, or if the travel switch 30 outputs an overflow alarm signal, the material conveying device of the food waste treatment system 1000 is controlled to stop feeding;

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

[0093] It can be understood that only when the jam alarm device makes a misjudgment and fails to detect the jam failure of the extruder 300, will it continue to determine whether the overflow alarm device 100 sends an overflow alarm signal; that is, in the process of garbage disposal by the system, as long as the jam alarm device outputs a jam alarm signal, or the overflow alarm device 100 outputs an overflow alarm signal, the food waste disposal system 1000 can immediately control the material conveying equipment to stop feeding, and then carry out subsequent material clearing processing; if neither of them outputs an alarm signal, it indicates that the extruder 300 is working normally and there is no jam failure.

[0094] Therefore, the method for handling kitchen waste machine blockage also has the advantages of high detection accuracy and good reliability. It can handle machine blockage failures in a short time and quickly resume production, thereby improving production efficiency.

[0095] It should be noted that the material conveying equipment mentioned in the above step S30 includes the conveyor 200, that is, after the machine jam occurs, it is necessary to first stop the conveyor 200 from continuing to convey the material, and then use the material cleaning device 302 to clean the material in the extrusion shell 301. Of course, for those skilled in the art, it is easy to know that the material conveying equipment of the kitchen waste treatment system 1000 can also include a garbage truck, a sorting and screening device, a bag breaker or a crusher, etc. When the machine jam occurs, it is necessary to control the various devices of the material conveying equipment in turn to stop feeding in turn, so as to facilitate the subsequent material cleaning operation.

[0096] In addition, it should be noted that the food waste treatment system 1000 also includes a controller (not shown in the figure), which is used to obtain machine blockage alarm signals and overflow alarm signals, and to control the start and stop operations of material conveying equipment and equipment such as the extruder 300, that is, to control the operation of the garbage truck, sorting and screening device, bag breaker, crusher, conveyor 200 and extruder 300.

[0097] Since in this embodiment, the cleaning device 302 includes a hydraulic cylinder 3021 , a spindle motor 3023 and a flushing water pump 3025 , 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] Specifically, please refer to Figure 7 , Figure 7 for Figure 6 The flowchart of the first sub-step of step S40 in Figure 6 and Figure 7 , step S40 comprises:

[0099] Sub-step S42a: controlling the hydraulic cylinder 3021 to retract to the initial position and stay there for a first time period;

[0100] Sub-step S43a: controlling the hydraulic cylinder 3021 to extend to a preset position and stay there for a second time period;

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

[0102] That is to say, when the hydraulic cylinder 3021 is retracted or extended, it can drive the screen 3022 to move, thereby increasing the volume of the extrusion area in the extrusion shell 301, reducing the extrusion force, and facilitating the cleaning of the plugged material.

[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 is retracted to the shortest length, and the preset position can be the position where the hydraulic cylinder 3021 is extended to the longest length.

[0104] Similarly, the specific values ​​of the first time length and the second time length can also be adjusted according to actual conditions. The first time length and the second time length can be the same or different. For example, the first time length can be set to 30s, and the second time length can also be set to 30s. That is, the hydraulic cylinder 3021 retracts and stays for 30s before extending, and continues to stay for 30s after extending to the preset position; this retraction and extension action of the hydraulic cylinder 3021 can be understood as moving forward or backward. 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 time length, 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 be extended immediately after retracting, or cannot be retracted immediately after extending. It is necessary to be forced to rest in the middle, which can protect the extruder 300 and prevent the hydraulic cylinder 3021 from being damaged due to excessive torque. At the same time, during this dwell time, it is also possible to wait for the cleaning operation of other components of the cleaning device 302 to cooperate with each other, thereby improving the cleaning effect.

[0106] It should be noted that during the material clearing operation, if the hydraulic cylinder 3021 cannot move and is completely blocked, it is necessary to exit the material clearing operation of the material clearing device 302 and switch to manual debugging. When the hydraulic cylinder 3021 can move, continue the material clearing operation.

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

[0108] Sub-step S41a: Control the hydraulic cylinder 3021 to stop working and stay for a third time period.

[0109] It should be noted that the third time 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 jam occurs, the controller will control the cleaning device to perform a cleaning operation. At this time, by first stopping the hydraulic cylinder 3021 and maintaining it for a certain period of time, an intermittent setting can also be reflected, thereby protecting the extruder 300 from damage caused by excessive torque of the hydraulic cylinder 3021, and waiting for the cleaning operation of other parts of the cleaning device 302 to cooperate, thereby further improving the cleaning effect.

[0110] Please refer to Figure 8 , Figure 8 for Figure 6 The flowchart of the second sub-step of step S40 in Figure 6 and Figure 8 , step S40 comprises:

[0111] Sub-step S42b: controlling the spindle motor 3023 to rotate in reverse for a fourth time period, and then controlling the spindle motor 3023 to stop for a fifth time period;

[0112] Sub-step S43b: controlling the spindle motor 3023 to rotate forward for a sixth time period, and then controlling the spindle motor 3023 to stop for a seventh time period;

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

[0114] That is to say, when performing the material clearing operation, by controlling the spindle motor 3023 to rotate forward or reverse, the material can be returned easily, thereby facilitating the cleaning of the jammed material.

[0115] It should be noted that the fourth duration, the fifth duration, the sixth duration and the seventh duration can be adjusted according to actual conditions, and the above-mentioned time can be the same or different. For example, the fourth duration and the sixth duration can be set to 30s, and the fifth duration and the seventh duration can be set to 15s, that is, the forward and reverse rotation of the spindle motor 3023 can be set to the same time, and the corresponding downtime is the same, that is, the spindle motor 3023 reverses for 30s and then stops for 15s, and then rotates forward for 30s and then stops for 15s. In this way, the forward or reverse rotation and the downtime operation of the spindle motor 3023 are repeated until the overall operation time of the spindle motor 3023 reaches the second preset cleaning time, and then the mode of controlling the spindle motor 3023 to clean the material is exited.

[0116] It can be understood that by controlling the spindle motor 3023 to perform this intermittent action, it can be ensured that the spindle motor 3023 cannot reverse immediately after rotating forward, or cannot rotate forward immediately after reversing, and is forced to rest in the middle. This can protect the extruder 300 and prevent the spindle motor 3023 from burning out due to frequent forward and reverse rotation or excessive instantaneous current without rest. At the same time, during this dwell time, it can also wait for the cleaning operation of other components of the cleaning device 302 to cooperate with each other, thereby improving the cleaning effect.

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

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

[0119] It should be noted that the eighth time length can also be adjusted according to the actual cleaning situation. Since the spindle motor 3023 is also rotating normally during the normal operation of the extruder 300, if a jam occurs, the controller will control the cleaning device to perform a cleaning operation. At this time, by first stopping the spindle motor 3023 and maintaining it for a certain period of time, an intermittent setting can also be reflected, thereby protecting the extruder 300, avoiding the spindle motor 3023 from frequently rotating forward and reverse or the instantaneous current is too large and does not get a rest, thereby burning the motor, and waiting for the cleaning operation of other parts of the cleaning device 302 to cooperate, thereby further improving the cleaning effect.

[0120] Please refer to Fig. 9 , Fig. 9 for Figure 6 The flowchart of the third sub-step of step S40 in Figure 6 and Fig. 9 , step S40 comprises:

[0121] Sub-step S42c: controlling the flushing water pump 3025 to flush the material in the extrusion housing 301 for a ninth time period;

[0122] Sub-step S43c: controlling the flushing water pump 3025 to stop flushing and maintaining the flushing for the tenth time period;

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

[0124] That is to say, when performing the material cleaning operation, the flushing water pump 3025 is controlled to flush and clean the plugged material in the extrusion shell 301 using the flushing pipeline 3024; at the same time, it can cooperate with the hydraulic cylinder 3021 and the screen 3022 to facilitate breaking up the material cake layer under the action of the flushing water.

[0125] It should be noted that the ninth time period and the tenth time period can be adjusted according to actual conditions, and the two times can be the same or different. For example, the ninth time period can be set to 30s, and the tenth time period can be set to 180s, that is, after the flushing water pump 3025 flushes for 30s, it stops flushing and maintains it for 180s; the flushing and stopping operations of the flushing water pump 3025 are repeated until the overall operation time of the flushing water pump 3025 reaches the third preset cleaning time, and then the mode of controlling the flushing water pump 3025 to clean the material is exited.

[0126] It can be understood that by controlling the flushing water pump 3025 to perform this intermittent flushing action, it is possible to wait for the cleaning operation of other components of the cleaning device 302 while stopping the flushing. That is, in this embodiment, wait for the forward or backward operation of the hydraulic cylinder 3021 and the forward or reverse operation of the spindle motor 3023. After the material has been cleaned to a certain extent through the above operations, the flushing water pump 3025 is turned on for flushing. In this way, the cleaning effect is improved through mutual coordination and cooperation.

[0127] Please continue to combine Fig. 9 Further, before sub-step S42c, step S40 further includes:

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

[0129] It should be noted that the eleventh time period can also be adjusted according to the actual cleaning situation. When the machine is blocked and the cleaning device 302 is controlled to clean the material, the flushing water pump 3025 is stopped first and maintained for a certain period of time, so as to ensure coordination with other components of the cleaning device 302. That is, in this embodiment, the hydraulic cylinder 3021 is waited for to move forward or backward, and the spindle motor 3023 is rotated forward or reversed, and the flushing water pump 3025 is turned on for flushing after the material is cleaned to a certain extent. In this way, the cleaning effect can be further improved.

[0130] In addition, it should be noted that the first duration, second duration...eleventh duration mentioned above are set as development parameters, which can be adjusted according to the actual cleaning situation. They have strong adaptability and versatility, and can be combined with various garbage disposal conditions and factors to comprehensively coordinate and set the cleaning time, further improve the cleaning effect and production efficiency, and the flushing water volume can also be controlled as needed, which can also save resources and reduce costs.

[0131] According to the above description, when the material is cleaned up and the machine blockage is resolved, the elastic member 40 needs to be reset manually, that is, the overflow cover 20 is engaged with the elastic member 40, the overflow port 11 is closed, and the travel switch 30 is disconnected. Such a setting can avoid strong impact or collision to cause compression or rebound of the elastic member 40, thereby ensuring the service life of the elastic member 40 and the travel switch 30.

[0132] It should be noted that the kitchen waste treatment system 1000 provided in this embodiment is based on safety considerations. Except for the elastic member 40 and the overflow cover 20, which need to be manually reset, the entire machine jam alarm, overflow alarm and subsequent material clearing operations are all automated, with high production efficiency. This not only avoids the frequent misjudgment of detection elements in the prior art, such as the misjudgment of local hanging materials inside the closed conveying equipment as material jams, which leads to frequent start and stop of the production line, not only the inability to accurately detect machine jams, but also the problem of greatly affecting production efficiency, but also can save a lot of manpower and material resources, and can handle the machine jam at the beginning of the occurrence, reducing the burden of material clearing, and the reliability of the system is good, which improves production efficiency.

[0133] In summary, the embodiments of the present invention provide an overflow alarm device 100, a kitchen waste treatment system 1000 and a method for treating a jam. The overflow alarm device 100 includes an overflow body 10, an overflow cover 20, a travel switch 30 and an elastic member 40. The overflow body 10 has an overflow port 11, and the overflow cover 20 is movably matched with the overflow body 10, and the overflow cover 20 is used to open or close the overflow port 11. The travel switch 30 is arranged on the overflow body 10, and is used to output an overflow alarm signal when triggered. The elastic member 40 is arranged on the travel switch 30, and the elastic member 40 is used to engage with the overflow cover 20 to keep the overflow cover 20 closed to the overflow port 11; and is used to trigger the travel switch 30 when the material 001 overflows from the overflow port 11 and pushes open the overflow cover 20, so that the overflow cover 20 is separated from the elastic member 40.

[0134] When the conveyor 200 is working normally, the overflow cover 20 is engaged with the elastic member 40, so that the overflow port 11 is closed, and the elastic member 40 will not trigger the travel switch 30 at this time; and when the kitchen waste treatment system 1000 has a machine jam failure, and the material 001 overflows from the overflow port 11, the material 001 will push open the overflow cover 20, so that the overflow cover 20 is separated from the elastic member 40, and the elastic member 40 will trigger the travel switch 30, so that the travel switch 30 outputs an overflow alarm signal. In this way, after receiving the overflow alarm signal, the kitchen waste treatment system 1000 will control each device to stop, and perform the subsequent machine jam cleaning operation of the extruder 300. It is easy to understand that the overflow alarm device 100 will not be disturbed by external factors such as light, material state, material layer height or vibration, and can avoid misjudgment when a machine jam occurs. It has high detection accuracy and good reliability, and can handle the machine jam failure in a short time and quickly resume production, thereby improving production efficiency.

[0135] The kitchen waste treatment system 1000 includes an overflow alarm device 100, a conveyor 200, an extruder 300 and a machine jam alarm device, wherein the overflow body 10 is arranged on the conveyor 200; the extruder 300 includes an extrusion shell 301 and a material cleaning device 302, the extrusion shell 301 is connected to the conveyor 200, and the material cleaning device 302 is arranged in the extrusion shell 301; the machine jam alarm device is arranged in the extrusion shell 301, and is used to output a machine jam alarm signal; wherein, when the travel switch 30 outputs an overflow alarm signal or when the machine jam alarm device outputs a machine jam alarm signal, the material cleaning device 302 is used to clean the material in the extrusion shell 301.

[0136] The jam alarm device can directly detect the jam situation of the extruder 300. When the extruder 300 is jammed, it outputs a jam alarm signal. After receiving the jam alarm signal, the kitchen waste treatment system 1000 will control each device to stop, and then control the cleaning device 302 to clean the material in the extrusion shell 301. When the jam alarm device is interfered by external factors such as light, material state, material layer height or vibration, and misjudgments and fails to detect the jam that has occurred, the material 001 will accumulate at the overflow port 11 through the conveyor 200, and then the overflow alarm device 100 will continue to be triggered, thereby issuing an overflow alarm signal, and then the kitchen waste treatment system 1000 will also control each device to stop, and then control the cleaning device 302 to clean the material in the extrusion shell 301. Therefore, the kitchen waste treatment system 1000 has high detection accuracy and good reliability, and can handle jam failures in a short time and quickly resume production, thereby improving production efficiency.

[0137] The method for handling kitchen waste jam machine is implemented using the kitchen waste treatment system 1000, which also has the beneficial effects of high detection accuracy, good reliability, the ability to handle machine jam failures in a short time, rapid resumption of production, and high production efficiency.
