Description

Technical Field

[0001] This utility model belongs to the field of kitchen waste degradation and treatment technology, specifically relating to a direct-discharge kitchen waste biodegradation machine. Background Technology

[0002] For drier food waste that does not contain bones, it can be directly put into a special treatment device. The device contains biodegradable agents, which can achieve immediate degradation and on-site disposal of the waste without any leakage. This direct discharge treatment of food waste achieves source control of food waste and effectively reduces the risk of secondary pollution during transportation.

[0003] For example, Chinese patent CN215696725U discloses a microbial degradation device for kitchen waste, including a lifting and dumping mechanism for raising and emptying the waste bin, a crushing mechanism for crushing the waste, a biodegradation mechanism for biodegrading the crushed waste, and an intermediate conveying mechanism for conveying the crushed waste to the biodegradation mechanism. The biodegradation mechanism includes a fermentation tank and a stirring mechanism, with a waste outlet at the lower end of the fermentation tank. The stirring mechanism includes a spiral stirring rod and a stirring drive mechanism for driving the spiral stirring rod to rotate. This device can process and transfer kitchen waste at the source, offering advantages such as low pollution, simple operation, and flexibility.

[0004] In current food waste treatment methods, degradation agents are mostly added manually and uniformly, then mixed and reacted with the food waste using the mixing components inside the degradation machine. In this mixing method, the mechanical mixing action of the mixing components makes it difficult for the agent to quickly disperse into the waste, initially leading to localized areas of excessively high or low agent concentrations. This prolongs the reaction cycle, resulting in inefficient and slow degradation of the food waste. Furthermore, incomplete degradation due to insufficient localized reactions can lead to residual pollutants. Simultaneously, the longer reaction time reduces the amount of waste processed per unit time, impacting overall treatment efficiency. Utility Model Content

[0005] Existing technologies using manual application of degradation agents often fail to achieve rapid dispersion of the agents within the waste, leading to localized areas of excessively high or low agent concentrations. This prolongs the reaction cycle, hindering the rapid and effective degradation of food waste and resulting in incomplete degradation and residual pollutants. This invention provides a direct-discharge food waste biodegradation machine that uses a spraying method to apply the degradation agents, combined with a semi-circular oscillation of the agent application pipe to ensure even application of the agent to the surface of the food waste within the degradation chamber. Compared to traditional manual application, this method achieves more uniform agent dispersion. The oscillating spray creates surface coverage, and the stirring function within the degradation chamber agitates the food waste, ensuring that all angles of the waste come into contact with the agent. This rapid and thorough mixing of the agent and food waste shortens the reaction cycle, improves degradation efficiency, avoids pollutant residues caused by incomplete localized reactions, reduces agent waste, and lowers treatment costs. The specific technical solution is as follows: A direct-discharge biodegradation machine for kitchen waste includes a degradation chamber, and further includes: a reagent delivery pipe, nozzles, an incomplete gear, and a rack. The reagent delivery pipe is rotatably disposed within the cavity of the degradation chamber, and its right end extends out of the cavity. Multiple sets of nozzles are provided, each set being disposed on the reagent delivery pipe. The incomplete gear is fixedly installed on the right end of the reagent delivery pipe. The rack is reciprocatingly disposed below the incomplete gear in a front-back direction, and is meshed with the incomplete gear. The rack reciprocates back and forth, driving the incomplete gear, the drug delivery tube, and the nozzle to oscillate within a semi-circular range.

[0006] In the above technical solution, the rack moves back and forth in the forward and backward direction through a drive unit. The drive unit includes a drive frame, a first motor frame, a first stepper motor, a drive rod, and a drive pin. The drive frame is fixedly and vertically installed below the rack, and a through slot is provided through the drive frame. The first motor frame is fixedly installed on the right side wall of the degradation chamber. The first stepper motor is installed on the first motor frame. One end of the drive rod is connected to the output end of the first stepper motor. The drive pin is connected to the other end of the drive rod, and the drive pin is slidably embedded in the through slot cavity of the drive frame.

[0007] In the above technical solution, the drive unit further comprises: two fixing plates, two guide rods and a connecting frame; the two sets of fixing plates are fixedly mounted on the right side wall of the degradation bin in a front-back corresponding manner; the two sets of guide rods are fixedly mounted between the two fixing plates in an up-down parallel manner; one end of the connecting frame is fixedly connected to the side wall of the rack, the other end is fixedly connected to the bottom end of the driving frame, and the connecting frame is slidably sleeved on the two sets of guide rods.

[0008] In the above technical solution, the connecting frame is configured in a "U" shape.

[0009] In the above technical solution, a mixing assembly is arranged in the inner cavity of the degradation bin, and the mixing assembly comprises: a second motor frame, a second stepping motor, a stirring shaft and a plurality of stirring blades; the second motor frame is fixedly mounted on the right side wall of the degradation bin; the second stepping motor is mounted on the second motor frame; the stirring shaft is rotatably arranged in the inner cavity of the degradation bin along the horizontal direction, and the stirring shaft is connected with the output end of the second stepping motor; a plurality of sets of the stirring blades are arranged, and the multiple sets of the stirring blades are arranged at equal intervals along the axial direction of the stirring shaft.

[0010] In the above technical solution, a discharge port is arranged at the bottom end of the front side wall of the degradation bin.

[0011] In the above technical solution, the top end of the degradation bin is provided with a feed inlet that can be opened and closed in a rotating manner, and a PLC controller is arranged on the side wall of the degradation bin.

[0012] In the above technical solution, an oil-water discharge port is arranged in communication at the bottom end of the left side of the degradation bin.

[0013] In the above technical solution, a temperature sensor is arranged in the inner cavity of the degradation bin.

[0014] Compared with the prior art, the direct-discharge kitchen waste biodegradation machine of the present utility model has the following beneficial effects: I. Existing methods of manually adding degradation agents are difficult to disperse quickly into the waste, often resulting in localized areas of excessively high or low agent concentrations. This prolongs the reaction cycle, hindering the rapid and effective degradation of food waste and leading to incomplete degradation and residual pollutants. This invention addresses this issue by using a spraying method to apply the degradation agent, combined with a semi-circular oscillation of the agent dispensing tube. This ensures the agent is evenly sprayed onto the surface of the food waste within the degradation chamber. Compared to traditional manual application, this method achieves more uniform agent dispersion. The oscillating spraying creates a surface coverage, and the stirring function within the degradation chamber agitates the food waste, ensuring that all angles of the waste come into contact with the agent. This allows for rapid and thorough mixing of the agent with the food waste, shortening the reaction cycle, improving degradation efficiency, avoiding residual pollutants caused by incomplete localized reactions, reducing agent waste, and lowering treatment costs. II. This utility model uses a rack and pinion to move back and forth, which can link an incomplete gear, a drug delivery pipe and a nozzle to complete a reciprocating swing motion, realizing the transformation of forward and backward displacement into reciprocating swing spraying of the nozzle; compared with the traditional method of using a forward and reverse motor to frequently switch the output drive direction to drive the nozzle to swing back and forth, this solution does not require frequent reversal of the motor output end, which can significantly reduce the reversal wear of the motor output shaft and related transmission components, reduce the probability of equipment failure, ensure stable and continuous spraying action, and improve the overall operational reliability of the equipment; Third, in this utility model, the drive rod and drive pin are rotated circumferentially by the first stepper motor, which can link the drive frame and rack to achieve linear displacement in the front-to-back direction. That is, this utility model relies on the first stepper motor to always maintain a single-direction drive output, without the need to switch directions, which can be converted into the back-to-back reciprocating movement of the rack, thereby driving the nozzle to complete the reciprocating oscillation to achieve the spraying of degradation agents. This design has several significant advantages: First, the first stepper motor always drives in a single direction, completely avoiding the mechanical wear caused by frequent changes in direction at the output end, greatly reducing the failure risk of the first stepper motor and related transmission components, and extending the service life of the core components of the equipment. Firstly, it reduces later operation and maintenance costs; secondly, it can realize the continuous motion transformation of a direct-discharge food waste biodegradation machine from "circumferential rotation → back-and-forth reciprocating movement → half-circumferential reciprocating oscillation". The entire transmission link does not require an additional reversing mechanism, simplifying the structure of the equipment transmission system and reducing component redundancy and assembly difficulty; thirdly, the single-direction drive mode makes the first stepper motor run more stably and output power more balanced, which not only ensures the precise control of the nozzle oscillation amplitude and ensures the uniformity of the agent spray coverage, but also avoids equipment vibration caused by reversing impact, improving the overall operational stability and fully reflecting the combination of design ingenuity and practicality. In summary, this utility model has several significant advantages: By using a spraying method combined with the semi-circular reciprocating oscillation of the agent delivery pipe to achieve surface-covering application of the degradation agent, and by combining this with the stirring function within the degradation chamber to agitate the kitchen waste, the agent is more evenly dispersed and thoroughly mixed with the waste, effectively shortening the reaction cycle, improving degradation efficiency, avoiding pollutant residues caused by incomplete local reactions, and simultaneously reducing agent waste and lowering treatment costs; by using a drive rack and pinion to reciprocate in a linked, partially oriented gear, agent delivery pipe, and nozzle to achieve the reciprocating oscillation, frequent reversing of the motor output is eliminated, significantly reducing commutation wear on the motor and transmission components, lowering the probability of equipment failure, and ensuring stable spraying action. Continuous operation enhances overall operational reliability. Driven by a single-direction stepper motor, the drive rod and drive pin rotate circumferentially, linking the drive frame and rack to achieve forward and backward reciprocating movement. This, in turn, drives the nozzle to oscillate back and forth, completely avoiding mechanical wear caused by frequent changes in direction at the output end. This extends the service life of core components, reduces maintenance costs, and eliminates the need for an additional reversing mechanism, simplifying the transmission system structure and reducing assembly difficulty. Simultaneously, it makes the stepper motor more stable and the power output more balanced, ensuring precise control of the nozzle's oscillation amplitude and uniform pesticide spray coverage. It also avoids equipment vibration caused by reversing impacts, further improving overall operational stability and demonstrating a high degree of integration between ingenious design and practicality.

[0016] The following are specific implementation cases and appendices. Figures 1 to 6The present invention will be further described below, but the present invention is not limited to these embodiments.

[0017] A direct-discharge biodegradation machine for kitchen waste includes a degradation chamber 1, and further includes: a reagent delivery pipe 2, a nozzle 3, an incomplete gear 4, and a rack 5. The reagent delivery pipe 2 is rotatably mounted inside the degradation chamber 1, with its right end extending out of the chamber. Multiple sets of nozzles 3 are provided, each mounted on the reagent delivery pipe 2. The reagent delivery pipe 2 can reciprocate within a half-circle without affecting the sealing of its connection with the degradation chamber 1. When the reagent delivery pipe 2 is connected to an external degradation reagent storage tank, a rotating bearing is used for the rotatable connection, and an external pump pumps the reagent from the storage tank into the delivery pipe 2, which is then sprayed through the nozzles 3. This design ensures both the sealing of the connection between the reagent delivery pipe 2 and the external degradation reagent storage tank, and also allows the reagent delivery pipe 2 to reciprocate within a normal half-circle. The connections of the reagent delivery pipe 2, the external pump, the degradation reagent storage tank, and the aforementioned components are all existing... The components are commercially available and of mature technology. Their combination is sufficient to achieve the effect of spraying the pesticide from the pesticide storage tank via the pesticide dispensing pipe 2 and the nozzle 3. Further details and limitations are omitted here. An incomplete gear 4 is fixedly installed at the right end of the pesticide dispensing pipe 2. A rack 5 is positioned below the incomplete gear 4, reciprocating in the front-back direction, and meshes with the incomplete gear 4. The number of teeth and meshing parameters on the incomplete gear 4 and rack 5 are compatible, sufficient to meet the requirement of the pesticide dispensing pipe 2 to perform a 180-degree reciprocating oscillation, and ensuring that the incomplete gear 4 and rack 5 do not experience tooth loss or other malfunctions during their normal service life. Commercially available general-purpose models of the incomplete gear 4 and rack 5 are used, and only models and parameters meeting the above requirements are needed. Further details and limitations are omitted here. The reciprocating movement of the rack 5 drives the incomplete gear 4, pesticide dispensing pipe 2, and nozzle 3 to perform a reciprocating oscillation within a semi-circular range. In this invention, by driving the rack 5 to reciprocate in the front-to-back direction, the incomplete gear 4, the agent dispensing pipe 2, and the nozzle 3 can be driven to synchronously complete the reciprocating swing motion, thereby converting the front-to-back displacement of the rack 5 into the reciprocating swing spraying motion of the nozzle 3. Compared with the traditional technology that relies on the frequent switching of the output drive direction of the forward and reverse motors to drive the nozzle 3 to swing back and forth, this solution does not require the motor output end to frequently change direction, which can significantly reduce the wear of the motor output shaft and related transmission components caused by the change direction, reduce the probability of equipment failure, ensure the stable and continuous spraying action of the nozzle 3, and thus improve the overall operational reliability of the equipment.

[0018] This invention delivers the degradation agent via spraying, while the agent delivery pipe 2 oscillates back and forth in a semi-circular motion to ensure the agent evenly covers the surface of the food waste within the degradation chamber 1. Compared to traditional manual feeding, this method achieves more uniform agent dispersion. The reciprocating spraying creates surface coverage, and the stirring function within the degradation chamber 1 agitates the food waste, ensuring that all angles of the waste are exposed to the agent, thus quickly and thoroughly mixing the agent with the food waste. This not only shortens the reaction cycle and improves degradation efficiency but also avoids pollutant residues due to incomplete local reactions, reduces agent waste, and lowers treatment costs.

[0019] The rack 5 reciprocates in the front-to-back direction via a drive unit, which includes a drive frame 6, a first motor frame 7, a first stepper motor 8, a drive rod 9, and a drive pin 10. The drive frame 6 is fixed and vertically installed below the rack 5, and a through slot is provided through the drive frame 6. The first motor frame 7 is fixedly installed on the right side wall of the degradation chamber 1. The first stepper motor 8 is installed on the first motor frame 7. One end of the drive rod 9 is connected to the output end of the first stepper motor 8. The drive pin 10 is connected to the other end of the drive rod 9, and the drive pin 10 is slidably embedded in the cavity of the through slot of the drive frame 6.

[0020] In this invention, the first stepper motor 8 provides driving force, causing the drive rod 9 and drive pin 10 to rotate circumferentially, which in turn links the drive frame 6 and rack 5 to achieve linear displacement in the front-to-back direction. In other words, this invention relies on the first stepper motor 8 to maintain a single-direction drive output, without switching the rotation direction, to convert its power into the back-to-back reciprocating movement of the rack 5, ultimately driving the nozzle 3 to complete the reciprocating oscillation, thereby achieving the spraying operation of the degradation agent. This design boasts several significant advantages: First, the first stepper motor 8 always drives in a single direction, fundamentally avoiding mechanical wear caused by frequent reversal at the output end. This significantly reduces the risk of failure for the first stepper motor 8 and related transmission components, extends the service life of the core components, and reduces subsequent maintenance costs. Second, it enables the direct-discharge kitchen waste biodegradation machine to achieve a continuous motion transformation of "circumferential rotation → forward and backward reciprocating movement → half-circumferential oscillation." The entire transmission process does not require an additional reversing mechanism, simplifying the structure of the equipment's transmission system and reducing component redundancy and assembly difficulty. Third, the single-direction drive mode makes the first stepper motor 8 operate more stably and output power more evenly. This ensures precise and controllable oscillation amplitude of the nozzle 3, guaranteeing uniform spray coverage of the pesticide, while also avoiding equipment vibration caused by reversing impacts. This enhances the overall operational stability of the equipment, fully demonstrating the ingenious design and practical value.

[0021] The drive unit also includes: a fixed plate 11, guide rods 12, and a connecting frame 13. Two sets of fixed plates 11 are fixedly installed on the right side wall of the degradation chamber 1, corresponding to each other. Two sets of guide rods 12 are fixedly installed between the two fixed plates 11, parallel to each other vertically. One end of the connecting frame 13 is fixedly connected to the side wall of the rack 5, and the other end is fixedly connected to the bottom end of the drive frame 6. The connecting frame 13 is slidably sleeved on the two sets of guide rods 12. The connecting frame 13 is U-shaped. Through the connection of the connecting frame 13, when the rack 5 and the drive frame 6 move, the connecting frame 13 can move relative to the two guide rods 12, thus limiting the direction of movement of the rack 5 and the drive frame 6, and effectively ensuring the meshing of the rack 5 and the incomplete gear 4.

[0022] The degradation chamber 1 is equipped with a mixing assembly, which includes a second motor frame 14, a second stepper motor 15, a stirring shaft 16, and stirring blades 17. The second motor frame 14 is fixedly installed on the right side wall of the degradation chamber 1; the second stepper motor 15 is installed on the second motor frame 14; the stirring shaft 16 is rotatably disposed in the inner cavity of the degradation chamber 1 in the horizontal direction, and the stirring shaft 16 is connected to the output end of the second stepper motor 15; multiple sets of stirring blades 17 are provided, and the multiple sets of stirring blades 17 are equidistantly arranged along the axial direction of the stirring shaft 16.

[0023] A discharge port 18 is provided at the bottom of the front side wall of the degradation chamber 1. The discharge port 18 is a rotatable and closable door. When closed, it can form a sealed relationship with the degradation chamber 1. When open, it can scoop out the degraded material in the degradation chamber 1, leaving an opening space. The connection between the discharge port 18 and the degradation chamber 1 is existing technology, which can meet the above-mentioned usage requirements and will not be described in detail or limited here. A feeding port 19 is provided at the top of the degradation chamber 1, which can be rotated and opened. A PLC controller 20 is provided on the side wall of the degradation chamber 1. The PLC controller 20 is a digital computing controller with a microprocessor for automatic control, which can load control instructions into memory for storage and execution at any time. The programmable controller consists of a CPU, instruction and data memory, input / output interface, power supply, digital-to-analog conversion and other functional units. It includes various functions such as logic control, timing control, analog control, and multi-machine communication. In this application, the PLC controller 20 can control the start-up, shutdown, timing, and other operational sequences and effects of various components. The PLC controller 20 can control and adjust corresponding instructions, which is prior art. The connection and control methods with the components in this application are also existing common technologies, and will not be elaborated or limited here. An oil-water drain outlet 21 is connected to the bottom left side of the degradation chamber 1. The oil-water drain outlet 21 is connected to an external oil-water separator for subsequent oil-water separation treatment. This is prior art, and it is sufficient to meet the usage requirements; it will not be elaborated or limited here. A temperature sensor 22 is installed inside the degradation chamber 1. The temperature sensor 22 is a commercially available, general-purpose sensor capable of sensing the temperature inside the degradation chamber 1. This is prior art, and it is sufficient to meet the usage requirements; it will not be elaborated or limited here.

[0024] In addition, in this application, the first stepper motor 8 and the second stepper motor 15 are common motor models available on the market, which can meet the above-mentioned usage requirements, and will not be elaborated or limited here.

[0025] The working principle of a direct-discharge food waste biodegradation machine in this embodiment is as follows: When degrading food waste, the food waste to be treated is first put into the inner cavity of the degradation chamber 1 through the feeding port 19; then the external pump is started to transport the degradation agent along the agent delivery pipe 2 to the nozzle 3, and the nozzle 3 sprays the food waste in the inner cavity of the degradation chamber 1 to lay the foundation for the full interaction between the agent and the waste. During this process, the first stepper motor 8 is started, which drives the drive rod 9 and the drive pin 10 to rotate circumferentially. The drive pin 10 synchronously drives the drive frame 6 and the rack 5 to reciprocate in the front-back direction, while causing the connecting frame 13 to complete the corresponding movement along the guide rod 12. The rack 5, which reciprocates back and forth, further drives the incomplete gear 4 to reciprocate in a semi-circular range, thereby driving the agent dispensing pipe 2 and the nozzle 3 to reciprocate in a semi-circular range. This transmission mechanism, in conjunction with the continuous spraying of the degradation agent by the nozzle 3, can ensure that the degradation agent evenly covers the surface of the kitchen waste in the degradation chamber 1. At the same time, the second stepper motor 15 is started, which drives the stirring shaft 16 and stirring blades 17 to rotate. During the process of stirring and mixing the kitchen waste in the degradation chamber 1, the degradation agent is sprayed evenly and repeatedly, so that all parts of the kitchen waste can quickly and effectively contact the degradation agent, and finally achieve efficient and rapid degradation of the kitchen waste. This invention offers several significant advantages: Firstly, the spraying method, combined with the semi-circular reciprocating oscillation of the agent delivery pipe 2, achieves comprehensive application of the degradation agent. Secondly, the stirring function within the degradation chamber 1 agitates the kitchen waste, ensuring more even dispersion and thorough mixing of the agent. This effectively shortens the reaction cycle, improves degradation efficiency, avoids pollutant residue caused by incomplete local reactions, reduces agent waste, and lowers treatment costs. Thirdly, the reciprocating oscillation of the drive rack 5, in conjunction with the incomplete gear 4, agent delivery pipe 2, and nozzle 3, eliminates the need for frequent reversing of the motor output, significantly reducing wear on the motor and transmission components, lowering the probability of equipment failure, and ensuring stable and continuous spraying. The system enhances overall operational reliability. Driven by a single-direction stepper motor 8, the system uses a drive rod 9 and drive pin 10 to rotate in a circumferential direction, linking the drive frame 6 and rack 5 to achieve forward and backward reciprocating motion. This, in turn, drives the nozzle 3 to oscillate back and forth, completely avoiding mechanical wear caused by frequent changes in direction at the output end. This extends the service life of core components, reduces maintenance costs, and eliminates the need for an additional reversing mechanism, simplifying the transmission system structure and reducing assembly difficulty. Simultaneously, it makes the stepper motor 8 more stable and its power output more balanced, ensuring precise control of the nozzle 3's oscillation amplitude and uniform coverage of the pesticide spray. It also avoids equipment vibration caused by reversing impacts, further improving overall operational stability and demonstrating a high degree of integration between ingenious design and practicality.
