Description

Technical Field

[0001] The present invention relates to the field of sericulture equipment, and more particularly to a mulberry leaf disinfection, cleaning and drying line. Background Art

[0002] Before mulberry leaves are used to feed silkworm eggs, they need to be disinfected and cleaned. The disinfected and cleaned mulberry leaves can prevent pathogens from being eaten by silkworms from the source of feed, blocking the occurrence of diseases such as pebbles, and have a very good effect on the prevention and control of pebbles of original seeds. The disinfected and cleaned mulberry leaves cannot be fed to silkworm eggs immediately. They need to dry the surface moisture before feeding. At present, some use drying and air-drying methods for drying. Compared with drying, the drying temperature is low, which can better maintain the nutrition and appearance of mulberry leaves. With reference to prior art document 1, a mulberry leaf disinfection and cleaning process and system are disclosed. The system includes a lifting and selecting leaf machine, a first disinfector, a second disinfector, a first cleaning machine, a second cleaning machine, a buffer table and a control system. The mulberry leaves can be disinfected and cleaned. The mulberry leaves after cleaning and disinfection are dried on the ground or on a plastic rack. The system still has the following problems that need to be improved: 1. The drying section uses a floor drying or plastic rack drying method, which consumes a lot of labor. The degree of automation and drying efficiency still need to be further improved. 2. The production line operation from disinfection, cleaning, and drying to finished product is not truly realized. The degree of automation still needs to be improved. 3. The disinfection and cleaning equipment still needs to be further improved to improve the disinfection and cleaning efficiency. Based on these reasons, it is necessary to design an improved mulberry leaf disinfection, cleaning and drying line.

[0034] The present invention is further described in detail below with reference to examples so that those skilled in the art can implement the invention with reference to the description.

[0035] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0036] like Figure 1 and 3 As shown in Figure 9, a mulberry leaf disinfection, cleaning and drying line comprises:

[0037] Several disinfection sections 10 provide a space for mulberry leaf immersion and disinfection. The immersion and disinfection space has a dynamic disinfection channel 130 constructed by a surface conveyor mesh belt 110, an underwater conveyor mesh belt 120, a stirring mechanism 140, and a bubbling device 150. The mulberry leaves move under the downward pressure and driving action of the conveyor mesh belt and are immersed and disinfected under the action of stirring and bubbles.

[0038] The multi-stage cleaning section 20 receives the mulberry leaves from the disinfection section 10 and has an immersion cleaning channel 2104 and a climbing cleaning channel 2109 constructed with a conveyor mesh belt. The mulberry leaves are immersed, flushed by water sprays, and acted upon by bubbles in the immersion cleaning channel 2104. After climbing, lifting, and flushing in the climbing cleaning channel 2109, the leaves enter the next stage.

[0039] The drying section 60 has a drying channel open to the external environment constructed by several layers of drying conveyor belts 610. The drying channel has an upward airflow. The cleaned mulberry leaves are transported along the drying channel and dried by wind and layer-by-layer turning to dry the surface moisture.

[0040] In this embodiment, a disinfection, cleaning and drying treatment process is used, and each process section is based on a conveyor mesh belt. The disinfection section, cleaning section, and drying section are all designed based on the conveyor mesh belt, which effectively improves the degree of mechanical automation of the disinfection, cleaning and drying operations, and the various processes are naturally connected and transitioned, saving manpower and improving efficiency.

[0041] Further, in another embodiment, Figure 1 and 8 As shown, it also includes a buffer section 30, which is located after the cleaning section 20 to receive the cleaned mulberry leaves. By adjusting the speed of the conveyor belt of the buffer section, the mulberry leaves are cached, and water drips out during the caching process. In the legend, the buffer section includes a buffer tank and a buffer conveyor belt. The buffer conveyor belt is located in the buffer tank. The bottom of the buffer tank is preferably set to a V-shaped structure that helps water converge, and then a water pipe is connected to drain the dripping water. The design of the buffer section provides a buffer space for adjusting the operating speed of the entire drying line. When the operating speed of the disinfection section and the cleaning section is too fast, too many mulberry leaves can be cached in the buffer section and thereby drip out some water. When the operating speed of the drying section of the rear section is too fast, the mulberry leaves in the buffer section can be replenished to the drying section in time, effectively avoiding idling of some sections of the drying line.

[0042] Further, in another embodiment, Figure 1 and 9 As shown, the dehydration section 40 is also included for dehydrating the mulberry leaves before they enter the drying section 60; the dehydration section includes a platform 410 and a dehydrator 420. The platform 410 receives and collects the mulberry leaves sent from the buffer section 30. After the workers put the mulberry leaves into the dehydrator 420 for dehydration, they put the dehydrated mulberry leaves into the material elevator 50, and the material elevator 50 supplies the mulberry leaves to the drying section. Preferably, the material elevator is a conveyor belt arranged at an angle. In this embodiment, a vertical dehydrator is used, so a manual auxiliary operation is required. During a dehydration operation, the worker pushes the mulberry leaves into the dehydrator and controls the dehydrator to rotate for 5 to 20 seconds to remove a large amount of water, saving a lot of drying time. After dehydration is completed, the worker takes out the mulberry leaves and pushes them into the material elevator 50.

[0043] Further, in another embodiment, Figure 3 As shown, the disinfection section 10 includes: a disinfection water tank 100 that provides a soaking and disinfection space, a surface conveying mesh belt 110 and an underwater conveying mesh belt 120 are arranged along the disinfection water tank, a mulberry leaf dynamic disinfection channel 130 is formed between the surface conveying mesh belt 110 and the underwater conveying mesh belt 120, steel plates 111 for enhancing the stirring effect are arranged on the surface conveying mesh belt 110 and the underwater conveying mesh belt 120, a stirring mechanism 140 is arranged at the rear end of the surface conveying mesh belt 110, and a bubbling device 150 is arranged along the bottom of the disinfection water tank 100.

[0044] Specifically, such as Figure 3 In the structure shown, (1) the disinfection tank 100 is mainly used to hold disinfectant solution. (2) the underwater conveyor belt 120 about 10 cm away from the bottom of the disinfection tank is mainly used to convey mulberry leaves and isolate them from the disinfectant residue at the bottom. (3) the surface conveyor belt 110 at the upper part of the disinfection tank is slightly shorter, and its main function is to press the mulberry leaves so that they are completely immersed in the disinfectant solution and conveyed forward. (4) two sets of stirring mechanisms 140 at the rear end of the upper part of the disinfection tank. The stirring mechanism includes a rotating shaft and stirring blades. The motor drives the stirring blades through the rotating shaft to stir and loosen the mulberry leaves so that the mulberry leaves are fully exposed to the disinfectant solution. In the figure, when the stirring blades rotate in the direction of mulberry leaf conveyance, they can also promote the mulberry leaves to enter the lifting conveyor belt 160. When the stirring blades rotate against the direction of mulberry leaf conveyance, they can hinder the mulberry leaves from moving onto the lifting conveyor belt 160, thereby increasing the residence time of the mulberry leaves in the disinfection tank and achieving the purpose of controlling the mulberry leaf conveying speed. Furthermore, the zigzag shape of the stirring blade can fully stir and loosen the mulberry leaves without damaging them, thus keeping the leaves intact. (5) A bubbling device 150 is installed at the bottom of the disinfection tank. When the disinfection machine is running, the bubbling device 150 starts to spray bubbles from the bottom to the top, causing the mulberry leaves in the disinfection tank to roll continuously.

[0045] The working principle is as follows: mulberry leaves enter the disinfection tank from the front end between the water surface and the underwater conveyor belt. The mulberry leaf dynamic disinfection channel 130 is completely immersed in the disinfectant. The mulberry leaves are pressed by the water surface and underwater conveyor belts, completely immersed in the disinfectant and slowly moving forward. The bubbler operates to release bubbles to break up the overlapping mulberry leaves and fully contact the disinfectant. The mulberry leaves are conveyed to the disinfection immersion tank. The stirring blades of the stirring mechanism at the rear end further stir the mulberry leaves, further contacting the disinfectant. By adjusting the conveying speed of the water surface and underwater conveyor belts and the stirring speed of the stirring mechanism, the time the mulberry leaves soak in the disinfectant in the disinfection tank is controlled to achieve comprehensive disinfection of the mulberry leaves. After disinfection is completed, the rotation direction of the stirring mechanism is adjusted to assist in the mulberry leaves to be transported out via the lifting conveyor belt 160.

[0046] Further, in another embodiment, Figure 2 As shown, the disinfection section 10 has two stages, including a first-stage disinfection section 11 and a second-stage disinfection section 12. The first-stage disinfection section is used for pre-disinfection treatment, and the second-stage disinfection section is used for deep disinfection treatment. In this embodiment, the first-stage disinfection section and the second-stage disinfection section are both filled with disinfectant containing 0.4% effective chlorine content. The mulberry leaves are immersed in the first-stage disinfection section for 2 minutes for pre-disinfection treatment to effectively remove the dirt, dust, insects and eggs, etc. adhered to the mulberry leaves. The mulberry leaves are immersed in the second-stage disinfection section for 8 minutes for deep and sufficient disinfection.

[0047] Further, in another embodiment, Figure 1 and 4 As shown, the washing section includes an immersion washing trough 2101 and a climbing washing trough 2107. A conveyor mesh belt is constructed at the bottom of the immersion washing trough 2101 and the climbing washing trough 2107, forming an immersion washing channel 2104 and a climbing washing channel 2109 that can drive the mulberry leaves. Water spray units are installed along the immersion washing trough and the climbing washing trough to spray water downward to flush the mulberry leaves. A foaming device is installed along the bottom of the immersion washing trough. In the example, a two-stage washing section is used, including a first washing section 210 and a second washing section 220. In the first washing section, the immersion washing conveyor mesh belt 2102, the immersion washing spray unit 2105, and the immersion washing foaming device 2103 are installed in the immersion washing trough 2101, and the climbing washing conveyor mesh belt 2108 and the climbing washing spray unit 2106 are installed above the climbing washing trough 2107. The second washing section has the same structure as the first washing section.

[0048] Further, in another embodiment, Figure 1 and 4 As shown, the soaking and cleaning water spray unit is configured to form a unidirectional water flow to push the mulberry leaves to move in the soaking and cleaning water tank.

[0049] Further, in another embodiment, Figure 1 and 4 As shown, the bottom 230 of the climbing cleaning water tank is connected to a water tank, which is used to receive water. When the cleaning section is multi-stage, the water received by the water tank is filtered and supplied to the immersion cleaning water tank spray unit of the same level and the climbing cleaning water tank spray unit of the previous level.

[0050] The operation process of the cleaning section is as follows: tap water is introduced by the spray unit for the ramp cleaning of the second cleaning section, and a multi-faceted high-pressure water curtain is formed at the ramp cleaning trough of the second cleaning section to rinse the mulberry leaves on the ramp conveyor belt. The water after the ramp cleaning of the second cleaning section flows to the bottom 230 of the ramp cleaning trough of the second cleaning section, and flows into the second large water reservoir through the top notch of the side of the bottom trough. After sedimentation and impurity removal in the large water reservoir, it is pumped to the immersion cleaning spray unit of the second cleaning section and the ramp cleaning spray unit of the first cleaning section via a water pump. The immersion cleaning spray unit of the second cleaning section is installed above the immersion cleaning trough. A clip-on nozzle is added to form a high-pressure flushing water curtain to rinse the mulberry leaves during the immersion cleaning. The water after the immersion cleaning of the second cleaning section flows into the small water reservoir through the opening at the bottom front end of the immersion cleaning trough of the second cleaning section. After sedimentation and impurity removal in the small water reservoir, it is pumped to the immersion cleaning trough of the first cleaning section for use. After the first washing section's ramp-up wash, the water flows to the bottom of the first washing section's ramp-up wash tank, then flows through a notch at the top of the bottom water tank into the first large water reservoir. After sedimentation and impurities removal in the first large water reservoir, it is pumped to the front end of the first washing section's immersion wash tank by a water pump. After passing through a clip nozzle, the water in the first washing section's immersion wash tank is flushed with mulberry leaves. The water in the first washing section's immersion wash tank is finally discharged through a drain outlet at the bottom front end of the immersion wash tank.

[0051] This embodiment realizes the multiple recycling of mulberry leaf washing water while ensuring the mulberry leaf washing effect, greatly reduces the water consumption for washing mulberry leaves, and achieves the purpose of saving water.

[0052] Further, in another embodiment, Figure 1 and Figures 5-7 As shown, in the drying section 60, the mulberry leaves move to the end of the conveyor mesh belt and then fall down to the conveyor mesh belt of the next layer; wherein, a baffle plate and a combing and dispersing mechanism are provided at the end of the conveyor mesh belt, the baffle plate is used to prevent the mulberry leaves from flying out of the lower conveyor mesh belt, and the combing and dispersing mechanism is in elastic contact with the conveyor mesh belt. When the conveyor mesh belt is running, the combing and dispersing mechanism is driven to vibrate and disperse the fallen mulberry leaves on the conveyor mesh belt of the next layer.

[0053] Specifically, in the figure, a total of seven layers of drying conveyor mesh belts 610 are set on the drying rack 640. The drying conveyor mesh belts 610 are driven by the drying conveyor motor 620. Several blowers 630 are set on the side of the drying rack. The blowers 630 provide airflow to the drying conveyor mesh belts 610 through air pipes, air valves 632 and air nozzles or air holes. In the figure, multiple air pipes cross the drying conveyor mesh belts 610. Air nozzles or air holes are set on the air pipes to blow air upward to form airflow. The air valves control the on and off of the air pipes to achieve the purpose of controlling the amount of airflow. A baffle plate 660 and a combing and dispersing mechanism 650 are set at the end of each layer of the drying conveyor mesh belt. The baffle plate 660 extends obliquely downward from the upper conveyor mesh belt to the top of the lower conveyor mesh belt. The baffle plate 660 can prevent the mulberry leaves falling from the upper layer from flying out of range, so that the mulberry leaves fall accurately into the lower conveyor mesh belt. As shown Figure 7 As shown, the combing and dispersing mechanism 650 specifically includes a rotating shaft 6501, a combing plate 6502 and a spring claw 6503; the combing plate 6502 is arranged between the baffle plate 660 and the drying conveyor belt 610 through the rotating shaft 6501, and the outermost combing plate 6502 is provided with a spring claw 6503, which is hinged on the combing plate 6502, and a support spring 6504 is provided between the spring claw 6503 and the combing plate 6502 so that the spring claw can elastically vibrate up and down. One end of the claw 6503 rests on the edges of the upper surface of the drying conveyor mesh belt 610. One end of the claw 6503 engages with the mesh of the upper surface. As the conveyor mesh belt moves forward, the claw 6503 continuously interacts with the mesh of the upper surface of the drying conveyor mesh belt, driving the combing plate to vibrate or bounce. When mulberry leaves from the upper drying conveyor mesh belt fall onto the combing plate, the vibrating combing plate drives the leaves to flip and disperse, effectively improving the leaf flipping effect and preventing the leaves from falling and piling up. This structural design is driven by the conveyor mesh belt, requiring no additional power, and can automatically adjust the vibration amplitude according to the operating speed of the conveyor mesh belt, providing adaptive functionality.

[0054] Further, in another embodiment, Figure 6 As shown, the drying section is set in an environment with controllable temperature and humidity. Each layer of the conveyor mesh belt is equipped with a humidity sensing unit. Based on the ambient humidity and the humidity of each layer of the conveyor mesh belt, the conveying speed and air flow of the drying section conveyor mesh belt are automatically adjusted to allow the mulberry leaves to dry to the set moisture content. In the figure, the external environment of the drying section is regulated by a refrigerator 670 and a dehumidifier 680 to adjust the temperature and humidity so that the external environment temperature and humidity of the drying section are within the set range, generally set to a humidity of less than 50% and a temperature of less than 20°C. Only when the external environment is relatively dry can the surface moisture of the mulberry leaves in the drying section be quickly dissipated. In order to promote rapid air flow, a circulating fan 690 can also be set to blow air towards the drying section.

[0055] In order to achieve automatic adjustment, the temperature and humidity of the surrounding environment of the drying section are sensed by temperature and humidity sensors, and the surrounding humidity is divided into gradients by a computer. The operating speed of the drying conveyor belt is also divided into gradients. When the actual humidity of the surrounding environment is in the corresponding humidity gradient, the computer controls the drying conveyor belt to operate at the corresponding speed gradient.

[0056] At the same time, each layer of drying conveyor belt is equipped with a humidity sensor to sense the surface humidity of mulberry leaves. The final drying humidity of the mulberry leaves, that is, the target humidity, is set by computer, and the difference between the target humidity and the surface humidity of the mulberry leaves is calculated. Then, according to the number of layers of the drying conveyor belt, the difference is evenly distributed to each layer of drying conveyor belt to form a drying task for each layer. The computer automatically adjusts the air flow corresponding to each layer of the conveyor belt to complete the drying task of each layer.

[0057] In one specific embodiment, the drying section has seven layers, each with a conveyor belt length of 11 meters and a width of 2 meters. When the ambient humidity is 20% to 30%, the conveyor belt speed is adjusted to 5 meters per minute; when the ambient humidity is 30% to 40%, the conveyor belt speed is adjusted to 4 meters per minute; and when the ambient humidity is 40% to 50%, the conveyor belt speed is adjusted to 3 meters per minute. A humidity sensor detects that the mulberry leaf humidity on the top drying conveyor belt is 95% to 97%, meaning the initial humidity of the mulberry leaves is 95% to 97%. The final drying target humidity is set at 81% to 83%, with a humidity difference of approximately 14%. This results in a drying task of approximately 2% for each layer of the conveyor belt. Based on the humidity detected by the humidity sensor on each layer of the conveyor belt, the computer automatically controls the airflow on each layer of the conveyor belt via an air valve, ensuring that the humidity of the mulberry leaves drops by approximately 2% after each layer of the conveyor belt. This configuration allows for precise control and automated regulation of the mulberry leaf drying process.

[0058] Furthermore, in another embodiment, the computer automatically adjusts the operating speed of the conveyor belts in the disinfection section and the cleaning section according to the transport speed of the conveyor belt in the drying section, thereby realizing the linkage control of the operating speed of the entire drying section.

[0059] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiment. They can be applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized.
