Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco processing technology, and in particular to a deep process cleaning device for a VAS vibrating fluidized bed in a cigarette production line. Background Technology
[0002] In the cigarette manufacturing process, the cooling bed is a key piece of equipment, and its operational stability directly affects the quality and production efficiency of cigarette products. Among the widely used cooling beds in the industry, the VAS vibrating fluidized bed is crucial. The VAS vibrating fluidized bed uses fans located on the outside of the equipment to provide airflow. The airflow passes through perforated baffles and V-shaped plates from bottom to top before entering the cooling bed, achieving fluidized cooling of the fibers. Excess air, dust, and other impurities are removed from the top of the cooling bed using a suction system to maintain a clean environment and stable process conditions. During long-term continuous operation, dust and soot gradually accumulate in the perforations of the perforated baffles and V-shaped plates, eventually clogging many of them. This obstructs airflow, reduces cooling and fluidization effects, and causes uneven fiber cooling and quality fluctuations. Therefore, timely cleaning of the perforated baffles and V-shaped plates is necessary.
[0003] Currently, the industry generally uses compressed air to gently blow clean. While this method can remove dust and soot from the surface and some shallow holes, it is not effective for cleaning deep inside the holes or stubborn blockages. Therefore, it is necessary to clean repeatedly, which not only prolongs the overall cleaning time but also increases the frequency of equipment downtime, thus increasing costs. Utility Model Content

[0026] Compared with the prior art, the deep cleaning equipment for the VAS vibrating fluidized bed in the cigarette production line provided in this embodiment of the invention has the following technical advantages:
[0027] 1. Because the cleaning mechanism is located below the cooling bed body, and the treatment tank is connected to the external water cleaning unit via a drain pipe assembly, and the external water cleaning unit and the gas jet cleaning unit are positioned directly opposite the perforated partition and V-shaped plate, when cleaning of the perforated partition and V-shaped plate is required, the drain pipe assembly delivers the cleaning fluid from the treatment tank to the external water cleaning unit. The external water cleaning unit sprays and cleans the perforated partition and V-shaped plate, clearing any blockages in the perforated partition and V-shaped plate. Then, the gas jet cleaning unit blows and cleans the perforated partition and V-shaped plate. Throughout the process, the cleaning mechanism works in conjunction with the external water cleaning unit and the air jet cleaning unit to achieve multiple cleaning of the perforated partitions and V-shaped plates. It can effectively unclog blocked holes and alleviate the situation where the jet cleaning effect is poor due to hole blockage. This not only shortens the overall cleaning time, but also ensures the cleaning effect of the perforated partitions and V-shaped plates, thereby reducing the cleaning frequency of perforated partitions and V-shaped plates between units, reducing downtime, and thus reducing costs.
[0028] 2. The top wall of the treatment tank is equipped with an inlet pipe for connecting to the drain outlet, and a filter screen is installed inside the treatment tank corresponding to the inlet pipe. Therefore, during the process of the external water cleaning unit spraying and cleaning the perforated partitions and V-shaped plates and unclogging the holes, the cleaned wastewater is collected on the bottom wall of the cooling bed body and flows back into the treatment tank through the drain outlet and the inlet pipe. After entering the treatment tank, the filter screen filters out impurities from the wastewater, and the filtered cleaning solution is stored in the treatment tank for the next spray cleaning and unclogging of the perforated partitions and V-shaped plates. In this way, the cleaning solution is recycled to further reduce costs. Attached Figure Description

[0053] Combination Figures 1 to 8As shown, this embodiment provides a deep cleaning device for a VAS vibrating fluidized bed cooling bed in a cigarette production line. This deep cleaning device is used to clean the perforated partitions and V-shaped plates installed inside the cooling bed body 10. This device improves the cleaning effect on the perforated partitions and V-shaped plates and reduces costs. Specifically, the cooling bed body 10 is equipped with an external water cleaning unit and a gas jet cleaning unit corresponding to the perforated partitions and V-shaped plates. A drain outlet 11 is provided on the bottom wall of the cooling bed body 10. The deep cleaning equipment for the VAS vibrating fluidized bed in the cigarette production line includes a cleaning mechanism 100 and a filtration mechanism. The cleaning mechanism 100 is located below the cleaning cooling bed body 10 and includes a treatment tank 110 and a drain pipe assembly 120. The treatment tank 110 is configured to treat and contain cleaning liquid. The top wall of the treatment tank 110 is provided with an inlet pipe 111 for communicating with a drain outlet 11. The drain pipe assembly 120 is connected to the bottom wall of the treatment tank 110 and is configured to communicate with an external water cleaning unit. The drain pipe assembly 120 is used to transport the cleaning liquid in the treatment tank 110 to the external water cleaning unit. The filtration mechanism includes at least one filter screen 210, which is correspondingly arranged in the treatment tank 110 with the inlet pipe 111.
[0054] Since the cleaning mechanism 100 is located below the cooling bed body 10, and the treatment tank 110 is connected to the external water cleaning unit via the drain pipe assembly 120, and the external water cleaning unit and the gas jet cleaning unit are positioned directly opposite the perforated partition and the V-shaped plate, when cleaning of the perforated partition and the V-shaped plate is required, the drain pipe assembly 120 delivers the cleaning fluid from the treatment tank 110 to the external water cleaning unit. The external water cleaning unit sprays and cleans the perforated partition and the V-shaped plate, clearing any blockages in the perforated partition and the V-shaped plate. Then, the gas jet cleaning unit sprays and cleans the perforated partition and the V-shaped plate. Throughout the process, the cleaning mechanism 100 works in conjunction with the external water cleaning unit and the air jet cleaning unit to achieve multiple cleaning of the perforated partitions and V-shaped plates. It can effectively unclog blocked holes and alleviate the situation where the jet cleaning effect is poor due to hole blockage. This not only shortens the overall cleaning time, but also ensures the cleaning effect of the perforated partitions and V-shaped plates, thereby reducing the cleaning frequency of perforated partitions and V-shaped plates between units, reducing downtime, and thus reducing costs.
[0055] The top wall of the treatment tank 110 is equipped with an inlet pipe 111 for connecting to the drain outlet 11. A filter screen 210 is installed inside the treatment tank 110 corresponding to the inlet pipe 111. Therefore, during the process of the external water cleaning unit spraying and cleaning the perforated partitions and V-shaped plates and unclogging the holes, the cleaned wastewater is collected on the bottom wall of the cooling bed body 10 and flows back into the treatment tank 110 through the drain outlet 11 and the inlet pipe 111. After entering the treatment tank 110, the filter screen 210 filters out impurities from the wastewater. The filtered cleaning solution is stored in the treatment tank 110 for subsequent spraying and cleaning of the perforated partitions and V-shaped plates and unclogging of the holes. This achieves the recycling of the cleaning solution, further reducing costs.
[0056] In this embodiment, when cleaning the perforated partition and V-shaped plate, spray cleaning is performed first, followed by blow cleaning, and tap water is used as the cleaning solution. In other embodiments, the cleaning solution may be alkaline cleaning solution, neutral surfactant cleaning solution, enzyme preparation cleaning solution, low concentration food-grade acidic cleaning solution, etc., and is not limited to tap water as used in this embodiment.
[0057] In addition, in this embodiment, an installation platform 12 is provided at intervals below the cooling bed body 10, and the deep process cleaning equipment of the VAS vibrating fluidized cooling bed of the cigarette production line is placed on the installation platform 12.
[0058] Preferably, the filtration mechanism further includes a power component 220. The processing box 110 is cylindrical, and multiple filter screens 210 are provided, each of which is circular. The multiple filter screens 210 are spaced apart in the processing box 110 along the vertical direction and are all connected to the power component 220. The power component 220 can drive the multiple filter screens 210 to rotate along the axis of the processing box 110.
[0059] Combination Figure 2 and Figure 3 As shown, the cross-sectional shape of the treatment box 110 and the multiple filter screens 210 are all set to circular along the vertical direction. This setting can, on the one hand, minimize the gap or filtration dead angle between the inner side of the treatment box 110 and the edge of the filter screen 210, thereby improving the removal effect of impurities in the sewage; on the other hand, when the power component 220 drives the multiple filter screens 210 to rotate around the circumference of the treatment box 110, interference between the filter screens 210 and the inner wall of the treatment box 110 is avoided, thereby ensuring the operational stability of the multiple filter screens 210.
[0060] From top to bottom, the mesh size of each filter screen 210 gradually increases. As the sewage flows downward in the treatment tank 110, the filtration effect on the sewage entering the treatment tank 110 is gradually enhanced, minimizing the amount of impurities remaining in the cleaning solution after filtration, so as to ensure the cleaning effect during the next spray cleaning of the perforated baffle and V-shaped plate.
[0061] In some other embodiments, a flow equalization element can be provided in the treatment tank 110. The flow equalization element is located above multiple filter screens 210 and is connected to the liquid inlet pipe 111. When sewage enters the treatment tank 110, it first passes through the flow equalization element for flow equalization treatment, so that the sewage is dispersed as much as possible, thereby increasing the contact area between the sewage and the filter screens 210, so as to improve the filtration effect and filtration efficiency.
[0062] In this embodiment, the specific facilities of the power assembly 220 are provided in two implementations, as follows:
[0063] In the first implementation method
[0064] The power assembly 220 includes a transmission rod 221, a limiting member 222, and multiple auxiliary blades 223. The limiting member 222 is fixed inside the processing box 110. The first end of the transmission rod 221 is inserted into a limiting hole on the limiting member 222, and the second end extends upward. Multiple filter screens 210 are all sleeved on the second end of the transmission rod 221. Multiple auxiliary blades 223 are spaced apart circumferentially on the transmission rod 221, and are spirally extended in the vertical direction. A drain pipe assembly is also included. The component 120 includes a first drain pipe 121, a second drain pipe 122, a third drain pipe 123, and an auxiliary pump 124. The two ends of the first drain pipe 121 are connected to the inside of the treatment tank 110 and the inlet of the auxiliary pump 124, respectively. The first end of the second drain pipe 122 is connected to the outlet of the auxiliary pump 124, and the second end is connected to the inside of the treatment tank 110 and is used to deliver cleaning fluid to multiple auxiliary blades 223. The two ends of the third drain pipe 123 are connected to the treatment tank 110 and the external water cleaning unit, respectively.
[0065] Combination Figure 3 and Figure 5 As shown, the limiting member 222 is fixedly installed inside the processing box 110 and located on the lower side of the processing box 110. The first end of the transmission rod 221 is inserted into the limiting hole on the limiting member 222. A transmission bearing is provided between the inner wall of the limiting hole and the transmission rod 221 to improve the convenience of the transmission rod 221 rotating around its own axis.
[0066] The principle by which the power unit 220 drives the rotation of multiple filter screens 210 is as follows: the auxiliary pump 124 draws cleaning fluid from the treatment tank 110 through the first drain pipe 121, and sprays the cleaning fluid onto multiple auxiliary blades 223 through the second drain pipe 122. Under the impact force of the cleaning fluid, the multiple auxiliary blades 223 rotate around the axis of the transmission rod 221, thereby driving the transmission rod 221 to rotate around its own axis, thus driving the multiple filter screens 210 to rotate. Throughout the process, the rotation of the multiple filter screens 210 is achieved solely by the cleaning fluid, which not only ensures the rotation effect but also saves energy consumption during rotation, further reducing costs. The third drain pipe 123 is used to transport the cleaning fluid in the treatment tank 110 to an external water cleaning unit for spray cleaning.
[0067] Furthermore, the limiting member 222 is configured as a limiting box with a cavity and is fixedly installed on the inner side of the bottom wall of the processing box 110. The limiting hole is set on the top wall of the limiting box. Multiple auxiliary blades 223 are located in the limiting box. The second end of the second drain pipe 122 and the third drain pipe 123 are both connected to the limiting box.
[0068] Combination Figure 3 As shown, multiple auxiliary blades 223 are all located within the limiting box. Therefore, when the second drain pipe 122 sprays cleaning fluid onto the multiple auxiliary blades 223, the impact force on the multiple auxiliary blades 223 is not weakened due to the influence of the cleaning fluid outside the limiting box, thus ensuring the rotation effect of the multiple auxiliary blades 223 and the transmission rod 221. In addition, in this embodiment, the limiting box is cylindrical, which can prevent the transmission rod 221 from experiencing a decrease in rotation effect due to turbulence after the cleaning fluid enters the limiting box. The third drain pipe 123 is connected to the limiting box, ensuring that the cleaning fluid can be delivered to the external water cleaning unit in a timely manner while ensuring that the force on the multiple auxiliary blades 223 is not affected by excessive cleaning fluid inside the limiting box.
[0069] In the second implementation method
[0070] Specifically, the power assembly 220 includes a transmission rod 221 and a rotary motor (not shown in the figure). The first end of the transmission rod 221 is inserted into the mounting hole in the bottom wall of the treatment tank 110 and extends out of the bottom wall of the treatment tank 110. The first end of the transmission rod 221 is connected to the output shaft of the rotary motor. The second end of the transmission rod 221 extends upward, and multiple filter screens 210 are sleeved on the second end of the transmission rod 221. The drain pipe assembly 120 includes a third drain pipe 123 and an output pump. The two ends of the third drain pipe 123 are respectively connected to the treatment tank 110 and the external water cleaning unit. The output pump is located in the third drain pipe 123.
[0071] In this embodiment, the limiting member 222 and multiple auxiliary blades 223 are not provided, nor are the first drain pipe 121, second drain pipe 122, and auxiliary pump 124. The first end of the transmission rod 221 is inserted into the mounting hole on the bottom wall of the treatment tank 110. A transmission bearing and a seal are provided between the inner wall of the mounting hole and the transmission rod 221 to improve the smoothness of the transmission rod 221 when rotating around its own axis and to ensure the sealing of the treatment tank 110. When sewage enters the treatment tank 110 from the inlet pipe 111, the rotary motor starts to drive the transmission rod 221 to rotate, thereby driving the transmission rod 221 to rotate around its own axis, thereby driving multiple filter screens 210 to rotate. By providing a rotary motor, the continuity and stability of the rotation of multiple filter screens 210 can be ensured. The third drain pipe 123 directly delivers the cleaning liquid in the treatment tank 110 to the external water cleaning unit through the output pump.
[0072] In some other embodiments, the mounting hole may also be provided on the top wall of the processing box 110, the second end of the transmission rod 221 extends upward and protrudes from the top wall of the processing box 110 through the mounting hole, the rotary motor is provided on the top wall of the processing box, and the output shaft of the rotary motor is connected to the second end of the transmission rod 221.
[0073] The above two implementation methods can be selected or set simultaneously; this embodiment does not impose any specific limitations.
[0074] Preferably, the deep process cleaning equipment for the VAS vibrating fluidized bed in the cigarette production line further includes an impurity cleaning mechanism 100. The impurity cleaning mechanism 100 includes multiple cleaning components, each of which is disposed in the processing box 110 in a one-to-one correspondence with multiple filter screens 210. Each cleaning component includes a mounting frame 310 and a cleaning element 320. The mounting frame 310 is fixed to the inner wall of the processing box 110 and extends radially along the processing box 110. The cleaning element 320 is disposed on the mounting frame 310 and can contact the upper surface of the corresponding filter screen 210.
[0075] Specific combination Figure 3 and Figure 5 As shown, with the discharge of wastewater and the rotation of multiple filter screens 210, impurities filtered by the filter screens 210 adhere to the upper surface of the corresponding filter screens 210. By setting up the mounting bracket 310 and the cleaning component 320, during the rotation of the filter screens 210, the mounting bracket 310 and the cleaning component 320 can scrape off and collect the impurities attached to the upper surface of the filter screens 210 for subsequent unified treatment. On the one hand, this reduces the probability that impurities attached to the upper surface of the filter screens 210 will be washed into the bottom of the treatment tank 110 with the flow of wastewater, ensuring the purity of the cleaning liquid at the bottom of the treatment tank 110; on the other hand, timely scraping off and cleaning the impurities attached to the upper surface of the filter screens ensures the real-time filtration effect of the filter screens 210.
[0076] Furthermore, the cleaning assembly also includes a cleaning shaft 330, a gear 340, and a transmission gear 350. The mounting bracket 310 is provided with a downward-facing cleaning groove that extends radially along the treatment box 110. The side wall of the treatment box 110 is provided with an avoidance opening corresponding to the cleaning groove. The cleaning shaft 330 is disposed in the cleaning groove and is provided with auger conveying blades 331 arranged spirally along its axial direction. The gear 340 is fixed to the second end of the transmission rod 221 and is located on the upper side of the corresponding filter screen 210. The transmission gear 350 is fixed to the first end of the corresponding cleaning shaft 330 and meshes with the corresponding gear 340.
[0077] Taking one of the cleanup components as an example, combined with Figure 3 , Figure 5 and Figure 6 As shown, the structure and working principle are explained. The length of the mounting bracket 310 is greater than the radius of the processing box 110. The first end of the mounting bracket 310 is fixedly connected to the inner wall of the processing box 110, and the second end extends radially into the processing box 110. The cleaning groove extends along the length of the mounting bracket 310, but does not penetrate the second end of the mounting bracket 310. A baffle 311 is provided on the side of the cleaning groove near the second end of the mounting bracket 310 to separate the mounting cavity 312 at the second end of the cleaning groove. An auxiliary hole is provided on the baffle 311. The first end of the cleaning shaft 330 is inserted into the auxiliary hole. An auxiliary bearing 332 is provided between the inner wall of the auxiliary hole and the first end of the cleaning shaft 330 to improve the smoothness of the rotation of the cleaning shaft 330. The transmission gear 350 is fixed to the first end of the corresponding cleaning shaft 330. The gear disk 340 is fixed to the second end of the transmission rod 221 and is located in the corresponding mounting cavity 312. The transmission gear 350 meshes with the gear disk 340. The cleaning shaft 330 is provided with auger conveying blades 331 extending along its axial direction. As the transmission rod 221 rotates, it drives the gear disc 340 to rotate. The transmission gear 350 meshes with the gear disc 340, causing the transmission gear 350 and the cleaning shaft 330 to rotate around the axis of the cleaning shaft 330. During the rotation of the cleaning shaft 330, the auger conveyor blades 331 rotate, thereby conveying the impurities accumulated on the mounting bracket 310 and cleaning component 320 on the filter screen 210 axially along the cleaning shaft 330 to the corresponding clearance opening, achieving automatic cleaning and discharge of impurities from the upper surface of the filter screen 210. Because a baffle 311 is provided on the side of the cleaning groove near the second end of the mounting bracket 310, it prevents impurities from entering the mounting cavity 312, thus avoiding any impact on the meshing effect of the transmission gear 350 and the gear disc 340.
[0078] Furthermore, the impurity cleaning mechanism 100 also includes multiple circulation modules 400, each of which includes a circulation box 410, a circulation pipe 420, and a circulation filter assembly 430. Each circulation box 410 is correspondingly disposed on the outer wall of the processing box 110 with multiple clearance openings. The circulation filter assembly 430 is disposed inside the corresponding circulation box 410. The first end of the circulation pipe 420 is connected to the bottom wall of the corresponding circulation box 410, and the second end of the circulation pipe 420 is connected to the processing box 110. The second end of the circulation pipe 420 is located at least above the bottom filter screen 210.
[0079] When the impurities accumulated on the mounting bracket 310 and cleaning component 320 on the filter screen 210 are axially conveyed along the cleaning shaft 330 to the outside of the corresponding clearance opening, they enter the corresponding circulation tank 410. The circulation filter assembly 430 then filters the cleaned impurities again to remove the cleaning fluid entrained in the impurities, and then reintroduces it into the processing tank 110 through the circulation pipe 420, further improving the utilization rate of the cleaning fluid. Simultaneously, since the cleaned impurities enter the circulation tank 410, as the impurities accumulate, the circulation tank 410 can be cleaned uniformly, preventing impurities from falling directly onto the mounting platform 12 and affecting the production environment. Furthermore, since the second end of the circulation pipe 420 is located at least above the bottom filter screen 210, the cleaning fluid entrained in the impurities enters the processing tank 110 after being filtered out. The filter screen 210 filters this portion of the cleaning fluid again, further improving the purity of the cleaning fluid at the bottom of the processing tank 110, thereby ensuring the cleaning effect on the perforated baffle and V-shaped plate.
[0080] To further increase the filtration area, thereby improving the filtration effect and efficiency, in this embodiment, the circulating filtration assembly 430 includes a collecting filter frame 431 and a central filter frame 432. The central filter frame 432 protrudes from the bottom wall of the collecting filter frame 431, and the collecting filter frame 431 communicates with a corresponding clearance opening. The size of the filter holes on the collecting filter frame 431 and the central filter frame 432 can be adaptively set according to actual needs, and this embodiment does not impose a specific limitation.
[0081] Furthermore, the impurity cleaning mechanism 100 also includes multiple auxiliary vibration modules, each of which includes an elastic reset component 510 and an eccentric wheel 520; the second end of the cleaning shaft 330 extends out of the corresponding clearance opening, the eccentric wheel 520 is fixed to the second end of the corresponding cleaning shaft 330 and abuts against the central filter frame 432, and the elastic reset component 510 is disposed in the corresponding circulation box 410 and is located between the bottom wall of the corresponding collection filter frame 431 and the bottom wall of the corresponding circulation box 410.
[0082] Combination Figure 8 and Figure 9As shown, in this embodiment, the collection filter frame 431 is set as a rectangular frame, and four sets of elastic reset components 510 are provided. The four sets of elastic reset components 510 are arranged between the bottom wall of the collection filter frame 431 and the bottom wall of the corresponding circulation box 410, corresponding to the four corners of the collection filter frame 431.
[0083] Taking one set of elastic reset components 510 as an example, the structure and working principle are analyzed. Specifically, the elastic reset component 510 includes a first mounting cylinder 511, a second mounting cylinder 512, and a reset spring 513. The reset spring 513 is a compression spring. The second end of the second mounting cylinder 512 is connected to the bottom wall of the circulation box 410, and the first end extends upward. The compression spring is set inside the second mounting cylinder 512. The lower end of the first mounting cylinder 511 is inserted into the first end of the second mounting cylinder 512, and the upper end is fixed to the bottom wall of the collection filter frame 431. When the cleaning shaft 330 rotates, it drives the eccentric wheel 520 to rotate. As the eccentric wheel 520 rotates, the resisting force on the central filter frame 432 changes. When the eccentric wheel 520 presses down on the central filter frame 432 and the collecting filter frame 431, the compression spring is compressed. Then, as the eccentric wheel 520 continues to rotate, the downward pressure on the central filter frame 432 and the collecting filter frame 431 decreases, and the downward pressure on the compression spring decreases simultaneously. At this time, the compression spring returns to its original state, pushing the central filter frame 432 and the collecting filter frame 431 to move upward. With the continuous rotation of the eccentric wheel 520, in conjunction with the compression spring, the central filter frame 432 and the collecting filter frame 431 vibrate in the vertical direction, thereby further improving the filtration effect and filtration efficiency.
