Description

Technical Field

[0001] This utility model relates to a cylinder cleaning device, specifically, to an intelligent cylinder cleaning device. Background Technology

[0002] After production operations are completed, dust and materials adhere to the inner walls of cylindrical equipment, such as the feeding rollers in cigarette manufacturing production lines. These rollers easily accumulate dust and materials and require frequent cleaning, essentially daily. Manual cleaning of this type of equipment is difficult, requiring personnel to enter the interior. Furthermore, due to the large size of the equipment, cleaning is challenging and inefficient. To improve the production efficiency of cylindrical equipment, automated production lines are now widely used. Manual cleaning clearly cannot meet the efficiency and effectiveness requirements of automated production lines.

[0003] For example, in the Chinese utility model patents already applied for by the applicant, CN202320870768.9 Rotary nozzle assembly for drum cleaning and CN202320110247.3 Rotary nozzle for cleaning box and drum equipment, a rotary nozzle that can freely enter or exit the inside of the drum equipment is adopted. The rotary nozzle itself can rotate 360 ​​degrees, so it can clean the inner wall of the drum equipment without dead angles.

[0004] However, in the aforementioned patent documents, the cleaning devices are generally not equipped with additional drying equipment. When drying the inner wall of the cylindrical equipment after cleaning, high-pressure air medium needs to be provided to the nozzle for drying. However, such cylindrical equipment cleaning devices are generally only equipped with one nozzle, and the nozzle has the characteristic of concentrated spraying. The effective impact range of a single nozzle is very small, which makes the drying efficiency of the cylindrical equipment low and the drying uneven. Therefore, it will require a long overall cleaning operation time. Moreover, the solution of using nozzles to spray compressed air for drying has the problem of high energy consumption, and compressed air needs to be used continuously for drying operations.

[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing an intelligent cylindrical equipment cleaning device. This device replaces the existing method of using nozzles to spray high-pressure air for drying with a blower, thereby improving drying efficiency and reducing drying energy consumption.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a base, a rotating nozzle, a fan, and a linear drive mechanism. The base is installed at the end of the linear drive mechanism, which drives the base to enter or exit the cylindrical equipment. The rotating nozzle is rotatably mounted on the base and is used to clean the inner wall of the cylindrical equipment. The fan is installed on the base and is used to dry the inner wall of the cylindrical equipment.

[0008] Based on the above, the fan is a ducted fan, and the ducted fan blows the inner wall of the cylindrical equipment along the axial direction of the cylindrical equipment.

[0009] Based on the above, a visual recognition camera is installed on the base, and the visual recognition camera is used to identify dirty areas inside the cylinder.

[0010] Based on the above, the air outlet direction of the fan is consistent with the outward extension direction of the rotating nozzle on the base, and the orientation direction of the visual recognition camera is consistent with the outward extension direction of the rotating nozzle on the base.

[0011] Based on the above, the rotating nozzle includes a first rotating joint and a first pipeline shaft. The fixed end of the first rotating joint is mounted on the base, and the rotating end of the first rotating joint is connected to the first pipeline shaft. The first pipeline shaft is mounted on the base through a bearing. The rotating nozzle is provided with a nozzle, and the nozzle rotates with the rotating nozzle as a whole.

[0012] Based on the above, the nozzle is rotatably mounted on the rotating nozzle head to adjust the angle of the nozzle on the rotating nozzle head, and the rotation axis of the nozzle is perpendicular to the rotation axis of the rotating nozzle head.

[0013] Based on the above, the rotary nozzle includes a second rotary joint and a second pipeline shaft, the nozzle is mounted on the second pipeline shaft, and the first pipeline shaft and the second pipeline shaft are rotatably connected through the second rotary joint.

[0014] Based on the above, the cleaning device also includes a U-shaped frame, the base is rotatably disposed within the U-shaped frame, and the base swings horizontally within the U-shaped frame.

[0015] Based on the above, the linear drive mechanism adopts a telescopic arm, which is connected to the back plate of the U-shaped frame to drive the U-shaped frame to move horizontally.

[0016] Based on the above, the cleaning device also includes a mobile trolley and a lifting base, wherein the lifting base is installed on the mobile trolley and the lifting end of the lifting base is connected to the outer cylinder wall of the telescopic arm.

[0017] This utility model has substantial features and advancements compared to the prior art. Specifically, this device, designed for the characteristics of cylindrical equipment, replaces the existing method of using nozzles to spray high-pressure air for drying with a blower. This results in a larger airflow and a wider drying coverage area, promoting the overall discharge of humid air from the cylinder and the replenishment of fresh dry air, thus creating an effective convective drying environment. Moreover, the unit energy required to drive a large flow of air is usually lower than the unit energy required to generate the same impact force with high-pressure compressed air, thereby reducing energy consumption while improving drying efficiency.

[0018] Meanwhile, the blower uses a ducted fan, and the ducted fan blows air in the axial direction of the cylindrical equipment, which can further increase drying efficiency and reduce drying energy consumption. This device is also equipped with a vision recognition camera to target dirty areas inside the cylinder, allowing the rotating nozzle to clean those areas specifically, thus ensuring cleaning effectiveness. This device ensures that the air outlet direction of the blower, the orientation of the vision recognition camera, and the outward extension direction of the rotating nozzle on the base are consistent, enabling the vision recognition camera to more effectively identify areas with severe dirt accumulation. The device allows the base to swing horizontally within a U-shaped frame, which in turn drives the rotating nozzle, blower, and vision recognition camera to swing horizontally, further increasing the cleaning range, drying range, and recognition range.

[0032] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0033] Example 1

[0034] like Figures 1-6 As shown, the intelligent cylindrical equipment cleaning device of this embodiment includes a base 1, a rotary nozzle 2, a fan 3, and a linear drive mechanism 6. The base 1 is installed at the end of the linear drive mechanism 6, and the linear drive mechanism 6 drives the base 1 to enter or exit the cylindrical equipment. The rotary nozzle 2 is rotatably mounted on the base 1. The rotary nozzle 2 increases the cleaning range by rotating inside the cylindrical equipment, that is, it sprays cleaning medium while rotating, so as to clean the inner wall of the cylindrical equipment. The fan 3 is installed on the base 1. The fan 3 uses wind power to accelerate the air flow in the inner cavity of the cylindrical equipment, so as to dry the inner wall of the cylindrical equipment after the rotary nozzle 2 has cleaned it.

[0035] In this application, the base 1 can be in the form of a frame to install the rotary nozzle 2 and the fan 3. The nozzle 25 of the rotary nozzle 2 and the front air outlet of the fan 3 are exposed on the base 1 to perform the cleaning and drying functions. The base 1 usually enters or exits the cylindrical equipment along the axial direction of the cylindrical equipment.

[0036] In this application, in order not to hinder the normal operation of the cylindrical equipment, the cleaning device as a whole uses a linear drive mechanism 6 to drive the base 1 into or out of the cylindrical equipment. For example, when it is necessary to clean the cylindrical equipment, the cylindrical equipment is stopped, and the base 1 drives the rotating nozzle 2 and the fan 3 into the interior of the cylindrical equipment to achieve the purpose of cleaning and drying the inner wall of the cylindrical equipment.

[0037] In this application, considering the characteristics of the cylinder equipment, a blower 3 is used instead of the existing solution of using nozzle 25 to spray high-pressure air for drying. This can bring a larger air flow and a larger drying coverage area, which can promote the overall discharge of humid air in the cylinder and the replenishment of fresh dry air, forming an effective convective drying environment. Moreover, since the use of air compressors and other equipment is avoided, the energy loss of air compression is reduced. Therefore, the unit energy required to drive a large flow of air (to produce the same air volume) is usually lower than the unit energy required to produce the same impact force of high-pressure compressed air. Overall, energy consumption can be reduced while improving drying efficiency.

[0038] Example 2

[0039] Based on Embodiment 1, in this embodiment, the fan 3 is a ducted fan; the ducted fan is also called a ducted axial flow fan, which adds a ducted fan housing 31 compared to an ordinary axial flow fan; the ducted fan, as prior art, is particularly suitable for the drying requirements of the cylindrical equipment in this application. The internal environment of the cylindrical equipment is generally low static pressure, and the drying requires a large air volume to increase the airflow; the impeller of the ducted fan is wrapped by an annular duct, which greatly improves the airflow at the blade tip, thereby bringing the advantages of improved drying efficiency, increased static pressure, and increased airflow.

[0040] Furthermore, directing the ducted fan towards the axial direction of the cylindrical equipment, compared to a method where the ducted fan blows directly towards the side wall of the cylindrical equipment, results in higher overall drying efficiency. When the airflow from the ducted fan reaches the end of the cylindrical equipment, the airflow rebounds at the end, forming a 360-degree circulation. This circulation sweeps across the entire inner wall surface of the cylindrical equipment, eliminating any dead zones and continuously removing moisture, preventing localized humidity saturation and achieving a forced convection dehumidification effect. Therefore, using the ducted fan to dry the inner wall of the cylindrical equipment along its axial direction, compared to the method of using nozzles 25 to spray high-pressure air, avoids situations where only localized areas are subjected to strong winds, wasteful and disordered rebound airflow, and the possibility of the rebound airflow carrying droplets and dirt towards already dried areas, further increasing drying efficiency and reducing drying energy consumption.

[0041] Regarding the end caps at the front and rear ports of the fan 3, for example, both the front and rear ends of the fan housing 31 of the fan 3 are equipped with openable and closable end caps. Since the opening at the front port of the fan 3 is relatively small, the front end cap 35 can be installed at the front port of the fan 3 using a hinged design. Because the rear port of the fan 3 has a larger opening (air inlet), it can be designed to open via a sliding mechanism. Specifically, the rear end of the fan housing 31 is equipped with a sliding rod 32, and the rear end cap 33 of the fan housing 31 slides along the axial direction of the fan 3 via the sliding rod 32 to open and close. A drive rod 34 can be installed outside the fan housing 31 to drive the rear end cap 33 to slide along the sliding rod 32, thereby opening or closing the rear end cap 33. The end caps at the front and rear ports of the fan 3 effectively prevent water stains or dirt from entering the fan 3 and affecting its performance.

[0042] In this embodiment, the use of a ducted fan for the blower 3 is a preferred embodiment. In other embodiments, the blower 3 can also be a common axial flow fan or a centrifugal fan, but the drying efficiency and drying range of the two are not as good as those of the ducted fan.

[0043] Example 3

[0044] Based on Embodiment 1 or Embodiment 2, a visual recognition camera 4 is installed on the base 1. The visual recognition camera 4 is used to identify the dirty areas inside the cylinder, so that the rotating nozzle 2 can perform targeted cleaning on the areas, thereby ensuring the cleaning effect.

[0045] For example, the relevant configuration of the vision system based on the vision recognition camera 4 is as follows: the vision recognition camera 4 adopts an 800W pixel or higher high-definition waterproof camera to ensure that the minimum coverage area occupied by the residual tobacco leaves in the image is 48*48 pixels, and to ensure that the computing power of a single high-definition camera configuration is not less than 2 TOPS.

[0046] For example, the relevant process for a vision system based on a vision recognition camera 4 is as follows: 1. Image acquisition: Use a high-resolution vision recognition camera 4 to acquire images of the inner wall of the cylinder equipment (hereinafter referred to as the cylinder wall) to ensure clear images that can capture obvious tobacco leaves and stains; 2. Image preprocessing: Preprocess the acquired images, including image denoising, contrast enhancement, and brightness adjustment, to improve image quality; 3. Model training: Train a deep learning model using a large dataset of labeled clean and uncleaned cylinder wall images, and through supervised learning, the model can learn the key features of residual tobacco leaves; 4. Detection and recognition: The trained model detects and recognizes the preprocessed images to determine whether the cylinder wall is clean. The model outputs a result indicating residual tobacco leaves, and the algorithm provides the target bounding box for the residual tobacco leaves; 5. Result feedback: Feedback the classification results to operators in real time or integrate them into the production system. For cylinder walls with a large amount of residual tobacco leaves, the system can trigger an alarm or prompt employees to repeat the cleaning process; 6. Continuous optimization: By continuously collecting new image data and classification results, the algorithm is iterated to improve classification accuracy.

[0047] In this embodiment, by configuring a vision system based on the vision recognition camera 4, the inner wall surface of the cylinder equipment is identified, so that the rotating nozzle 2 can focus on cleaning the dirty areas, avoiding unqualified cleaning and ensuring the cleaning effect. Moreover, no manual intervention is required, thereby meeting the food-grade production process requirements and hygiene and safety standards of the tobacco industry, and ultimately realizing fully automatic intelligent online cleaning operation of the cylinder equipment.

[0048] Example 4

[0049] Based on Embodiment 3, in this embodiment, the air outlet direction of the fan 3 is consistent with the outward extension direction of the rotating nozzle 2 on the base 1, and the orientation direction of the visual recognition camera 4 is consistent with the outward extension direction of the rotating nozzle 2 on the base 1. By keeping the air outlet direction of the fan 3, the orientation direction of the visual recognition camera 4, and the outward extension direction of the rotating nozzle 2 on the base 1 consistent, the visual recognition camera 4 can more efficiently identify areas with severe dirt accumulation. In order to keep the three consistent and still allow the rotating nozzle 2 to have a relatively wide cleaning range, the rotating nozzle 2 can adopt the following structure: The rotating nozzle 2 includes a first rotating joint 21 and a first pipeline shaft 22. The fixed end of the first rotating joint 21 is installed on the base 1, and the rotating end of the first rotating joint 21 is connected to the first pipeline shaft 22. The first pipeline shaft 22 is installed on the base 1 through a bearing. The first rotating joint 21 is used to connect the medium pipeline to provide cleaning medium for the nozzle 25. The nozzle 25 rotates as a whole with the rotating nozzle 2, and is rotatably mounted on the rotating nozzle 2 to adjust its angle on the rotating nozzle 2. The axis of rotation of the nozzle 25 is perpendicular to the axis of rotation of the rotating nozzle 2. Specifically, the rotating nozzle 2 includes a second rotary joint 23 and a second pipeline shaft 24. The nozzle 25 is mounted on the second pipeline shaft 24, and the first pipeline shaft 22 and the second pipeline shaft 24 are rotatably connected through the second rotary joint 23.

[0050] Regarding the driving method of the first pipeline rotating shaft 22 and the second pipeline rotating shaft 24, the first driving motor 26 can be used to drive the first pipeline rotating shaft 22 to rotate, and the first driving motor 26 is mounted on the base 1; the second driving motor 27 can be used to drive the second pipeline rotating shaft 24 to rotate, and the second driving motor 27 is mounted inside the rotating nozzle 2.

[0051] Regarding the form in which the first pipe shaft 22 is mounted on the base 1, it can be achieved by using a first rotary joint 21, a first bearing 28, and a second bearing 29 to connect the first pipe shaft 22. Assuming that the base 1 adopts a frame structure, including a front plate, a rear plate, an upper plate, and a lower plate, the first rotary joint 21 is connected to the rear plate of the base 1, the first bearing 28 is connected to the upper or lower plate of the base 1, and the second bearing 29 is connected to the front plate of the base 1. In this way, the rotating nozzle 2 can be rotatably mounted on the base 1.

[0052] For example, a slot can be provided at the front end of the rotating nozzle 2, and the nozzle 25 can be placed in the slot to allow it to swing. The main body of the first pipe shaft 22 is bent when passing through the slot, and the first pipe shaft 22 is connected to the second pipe shaft 24 from one side plate of the slot via the second rotary joint 23. A second drive motor 27 for driving the second pipe shaft 24 to rotate is installed in the other side plate of the slot. In this way, the slot rotates with the rotary joint 2, and the nozzle 25 swings within the slot to adjust the spray angle of the nozzle 25, so that the nozzle 25 has a wider coverage area. The rotating nozzle 2, including the slot portion, extends outward on the base 1, and the air outlet of the fan 3 is located at the rear of the slot portion to prevent interference between the fan 3 and the jet sprayed from the nozzle 25. Similarly, the visual recognition camera 4 can be located at the rear of the slot portion.

[0053] In other embodiments, the first pipe shaft 22, the second rotary joint 23, and the second pipe shaft 24 can be replaced by flexible hoses, as detailed in the rotary nozzle for cleaning box and drum equipment disclosed in CN202320110247.3.

[0054] Example 5

[0055] Based on Embodiment 4, the intelligent cylindrical equipment cleaning device of this embodiment further includes a U-shaped frame 5, a mobile trolley 7, and a lifting base 8. The base 1 is rotatably disposed within the U-shaped frame 5, and the base 1 swings horizontally within the U-shaped frame 5, which can drive the rotating nozzle 2, the fan 3, and the visual recognition camera 4 to swing horizontally. For example, when the rotating nozzle 2 swings horizontally, it can increase the cleaning coverage of the rotating nozzle 2 and prevent cleaning dead zones; when the fan 3 swings horizontally, it can finely adjust the air outlet angle of the fan 3 for complex inner wall structures of the cylindrical body to increase the drying coverage and prevent drying dead zones; when the visual recognition camera 4 swings horizontally, it can increase the recognition range of the visual recognition camera 4 and prevent recognition dead zones caused by the obstruction of the rotating nozzle 2 or the fan 3.

[0056] Regarding the driving method between the U-shaped frame 5 and the base 1, a waterproof electric rotary table 51 (or a motor gear drive) can be used.

[0057] In addition, the linear drive mechanism 6 adopts a telescopic arm, which is connected to the back plate of the U-shaped frame 5 to drive the U-shaped frame 5 to move horizontally, so that the frame 1 can enter or exit the cylindrical device.

[0058] In addition, the lifting base 8 is installed on the mobile trolley 7. The lifting end of the lifting base 8 is connected to the outer cylinder wall of the telescopic arm. The lifting base 8 can use a double column form to drive the telescopic arm to lift and lower. The mobile trolley 7 can be equipped with a storage tank for storing cleaning media, a pumping device for pressurizing the cleaning media, a hose for moving with the telescopic end of the telescopic arm, and a hose storage tray.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
