Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-sticking technology, specifically a self-cleaning anti-sticking mechanism. Background Technology
[0002] In modern industrial production, mixing equipment is a core component in chemical, pharmaceutical, and food industries. However, the common problem of material adhering to the tank wall seriously affects product quality, production efficiency, and energy consumption. Adhesion not only leads to pollution and waste but also causes frequent equipment downtime and increased maintenance costs, becoming a bottleneck restricting continuous and intelligent production. Therefore, developing efficient and intelligent self-cleaning anti-adhesion technology has become one of the key requirements for industry transformation and upgrading.
[0003] In the mixing and production processes of chemical, food, and pharmaceutical industries, materials tend to adhere to the inner wall of the tank due to their viscosity, humidity, and other characteristics. When the inner wall of the tank has a non-vertical structure such as a slope, cone, or sphere, traditional scrapers, which are mostly designed with fixed angles and heights, cannot adapt to the continuous changes in the angle of the inner wall's curvature. This results in cleaning dead zones at the junction of the slope and the tank body, and in the conical area. Although some solutions currently use a combination of spraying and scraping for cleaning, most do not consider the differences in material properties and the dynamic adaptation requirements of the inner wall's geometry. This leads to low cleaning efficiency and a lack of intelligent control capabilities, which can easily cause cleaning problems. Incomplete or excessive cleaning can cause wear and tear on the inner wall. For example, the utility model patent with authorization announcement number CN222871988U discloses a mixing device that facilitates cleaning of the inner wall. It achieves self-cleaning by creating vibrations through the impact of parallel scrapers on the barrier plate. However, this device still relies on a scraper structure with a fixed angle. Its cleaning effect depends on the degree of matching between the scraper and the inner wall with a preset shape. It is not adaptable to complex inner wall structures with varying angles and non-vertical surfaces. In particular, it is difficult to ensure full contact in sloping areas, and there are still cleaning dead corners. Therefore, we propose a self-cleaning anti-sticking mechanism. Utility Model Content
[0004] To address the aforementioned technical problems, this application provides a self-cleaning anti-sticking mechanism, comprising a fixed frame and a plate frame. A movable box is slidably mounted on the fixed frame, and an installation box is located below the movable box. A scraper is fixedly mounted on the plate frame, and an adjustment mechanism for adjusting the scraper angle is provided inside the installation box. An installation rod is rotatably mounted inside the movable box, and a first lifting rod is slidably mounted inside the installation rod. A second lifting rod is slidably mounted inside the first lifting rod, and the end of the second lifting rod away from the installation rod is fixedly connected to the installation box. Two sets of symmetrically distributed atomizing nozzles are fixedly mounted on both sides of the plate frame.
[0005] In some embodiments, multiple sets of equidistantly distributed ultrasonic sensors are fixedly installed inside the plate frame. The adjustment mechanism includes a rotating frame, which is rotatably connected to the mounting box via a rotating rod. A drive wheel is rotatably installed inside the mounting box. The plate frame is rotatably connected to the rotating frame via a mounting shaft. A worm gear is rotatably installed inside the rotating frame. A controller is fixedly installed on the movable box. The multiple sets of ultrasonic sensors are signal-connected to the controller.
[0006] In some embodiments, a gear is sleeved on the rotating rod, the drive wheel is meshed with the gear, a worm gear is sleeved on the mounting shaft, and the worm is meshed with the worm gear.
[0007] In some embodiments, the mounting rod is provided with a threaded rod, the upper end of which passes through the mounting rod and is rotatably connected to the mounting rod through a rolling bearing; the first lifting rod is provided with a threaded tube, the upper end of which passes through the first lifting rod and is rotatably connected to the first lifting rod through a rolling bearing.
[0008] In some embodiments, the lower end of the threaded rod passes through the first lifting rod and is threadedly connected, and the lower end of the threaded tube passes through the second lifting rod and is threadedly connected to the second lifting rod.
[0009] In some embodiments, the threaded rod is provided with two sets of symmetrically distributed limiting grooves, and the threaded tube is provided with two sets of symmetrically distributed limiting blocks. The limiting blocks are correspondingly arranged with the limiting grooves, and the threaded tube is slidably sleeved with the threaded rod through the limiting blocks and limiting grooves.
[0010] In some embodiments, a lead screw is rotatably mounted inside the fixed frame, the lead screw passing through the movable box and threadedly connected to the movable box.
[0011] This utility model has at least the following beneficial effects:
[0012] 1. Through the synergy of an angle adjustment structure and an intelligent detection system, precise cleaning of complex, non-vertical inner walls is achieved, avoiding the adaptation difficulties of traditional fixed scrapers. The rotating frame is rotatably connected to the mounting box via a rotating rod. The drive wheel meshes with a gear on the rotating rod, causing the rotating frame to rotate around the rod. Simultaneously, the worm gear inside the rotating frame meshes with a worm wheel on the mounting shaft, enabling fine angle adjustment of the mounting shaft, which in turn adjusts the contact angle of the scraper on the plate frame. Multiple sets of ultrasonic sensors fixed within the plate frame can detect changes in the shape of the tank's inner wall, such as slopes or cones, in real time, transmitting signals to the controller on the moving box for further control. The controller dynamically adjusts the mechanism based on detection data to ensure the scraper fits tightly against the non-vertical inner wall to the maximum extent, avoiding cleaning dead zones formed by traditional fixed-angle scrapers at the junction of the slope and the tank body, and in the transition area of the conical surface. At the same time, the atomizing nozzles on both sides of the plate frame can spray cleaning liquid simultaneously during the scraping process, forming a dual cleaning effect of scraping and spraying. For materials that are prone to adhesion in the chemical, food, and pharmaceutical industries, it can quickly remove the residue after scraping by the scraper. It has stronger adaptability to complex inner walls, significantly improves cleaning coverage, and can achieve efficient cleaning without relying on vibration, reducing damage to the tank body.
[0013] 2. Through the precise linkage of a multi-level lifting structure and a horizontal moving structure, the cleaning components achieve full coverage of the tank, further enhancing the ability to clean without blind spots, and the lifting drive logic is more in line with actual operating needs. The nested sliding design of the mounting rod, the first lifting rod, and the second lifting rod, combined with the motor-driven threaded rod transmission, constitutes a stable and efficient lifting system that can accurately adapt to the cleaning needs of tanks of different depths, avoiding the problems of limited adjustment range and insufficient adaptability of traditional single-stage lifting structures. At the same time, the screw rod rotatably installed in the fixed frame passes through the moving box and is threadedly connected to the moving box. Rotating the screw rod can drive the moving box to slide horizontally along the fixed frame, thereby pulling the cleaning components to move smoothly radially along the tank. Combined with precise lifting adjustment and angle adaptation, the scraper can completely cover all areas of the tank from top to bottom and from center to edge. Whether it is radial wide-range cleaning of large-diameter tanks or axial long-distance cleaning of deep-cavity tanks, it can achieve cleaning operations without omissions or deviations.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1:
[0022] Please see Figure 1-5 This utility model provides a technical solution: a self-cleaning anti-sticking mechanism, including a fixed frame 1 and a plate frame 5. A movable box 2 is slidably mounted on the fixed frame 1, and an installation box 4 is provided below the movable box 2. A scraper 6 is fixedly mounted on the plate frame 5. An adjustment mechanism 7 for adjusting the angle of the scraper 6 is provided inside the installation box 4. An installation rod 10 is rotatably mounted inside the movable box 2. A first lifting rod 11 is slidably mounted inside the installation rod 10. A second lifting rod 12 is slidably mounted inside the first lifting rod 11. The end of the second lifting rod 12 away from the installation rod 10 is fixedly connected to the installation box 4. Two sets of symmetrically distributed atomizing devices are fixedly mounted on both sides of the plate frame 5. The nozzle 8 and the fixed frame 1 provide a sliding support base for the movable box 2. The movable box 2 can drive the installation box 4 below and the cleaning components to move as a whole. The nested sliding structure of the installation rod 10, the first lifting rod 11 and the second lifting rod 12 can adjust the height of the installation box 4 by telescoping, thereby changing the vertical position of the plate frame 5 and the scraper 6 to adapt to tanks of different depths. The atomizing nozzles 8 on both sides of the plate frame 5 can spray cleaning liquid simultaneously during the scraping of the wall by the scraper 6, forming a dual cleaning effect of scraping and spraying with the scraping action of the scraper 6, quickly removing the material residue after the scraper 6 has scraped it, improving cleaning efficiency and preventing the material from accumulating on the inner wall of the tank.
[0023] Multiple sets of equidistantly distributed ultrasonic sensors 708 are fixedly installed inside the plate frame 5. The adjustment mechanism 7 includes a rotating frame 701, which is rotatably connected to the mounting box 4 via a rotating rod 702. A drive wheel 704 is rotatably installed inside the mounting box 4. The plate frame 5 is rotatably connected to the rotating frame 701 via a mounting shaft 705. A worm gear 707 is rotatably installed inside the rotating frame 701. A controller 3 is fixedly installed on the movable box 2. The multiple sets of ultrasonic sensors 708 are signal-connected to the controller 3. A gear 703 is sleeved on the rotating rod 702, and the drive wheel 704 is meshed with the gear 703. A worm wheel 706 is sleeved on the mounting shaft 705, and the worm gear 707 is meshed with the worm wheel 706. The ultrasonic sensors 708 inside the plate frame 5 can detect changes in the shape of the inner wall of the tank, such as slopes or cones, in real time, and transmit the detected signals. The signal is transmitted to the controller 3. After analyzing the difference in the inner wall angle based on the signal, the controller 3 controls the adjustment mechanism 7 to operate. When the drive wheel 704 rotates, it meshes with the gear 703 on the rotating rod 702, causing the rotating rod 702 and the rotating frame 701 to rotate around the mounting box 4, thus achieving the initial angle adjustment of the scraper 6. When the worm gear 707 inside the rotating frame 701 rotates, it meshes with the worm wheel 706 on the mounting shaft 705, causing the mounting shaft 705 and the plate frame 5 to rotate finely, further fine-tuning the angle of the scraper 6. The dual angle adjustment structure, combined with the intelligent linkage between the sensor and the controller 3, ensures that the scraper 6 can fit the non-vertical inner wall to the maximum extent, avoiding the formation of cleaning dead corners at the connection between the slope and the tank and the transition area of the conical surface by the traditional fixed-angle scraper 6. At the same time, it does not require vibration cleaning, reducing damage to the tank.
[0024] Example 2:
[0025] Please see Figure 1-2The mounting rod 10 has a threaded rod 13 inside. The upper end of the threaded rod 13 passes through the mounting rod 10 and is rotatably connected to the mounting rod 10 through a rolling bearing. The first lifting rod 11 has a threaded tube 15 inside. The upper end of the threaded tube 15 passes through the first lifting rod 11 and is rotatably connected to the first lifting rod 11 through a rolling bearing. The lower end of the threaded rod 13 passes through the first lifting rod 11 and is threadedly connected. The lower end of the threaded tube 15 passes through the second lifting rod 12 and is threadedly connected to the second lifting rod 12. The threaded rod 13 has two sets of symmetrically distributed limiting grooves 14. The threaded tube 15 has two sets of symmetrically distributed limiting blocks 16 inside. The limiting blocks 16 are correspondingly set with the limiting grooves 14. The threaded tube 15 is slidably sleeved with the threaded rod 13 through the limiting blocks 16 and the limiting grooves 14. The threaded rod 13 inside the mounting rod 10 rotates under the drive of the motor. Because the threaded tube 15 passes through the limiting blocks 16... The threaded tube 15 is slidably sleeved with the limiting groove 14 of the threaded rod 13. The limiting block 16 restricts the relative rotation between the threaded tube 15 and the threaded rod 13, so that the threaded tube 15 rotates synchronously with the threaded rod 13. The lower end of the threaded rod 13 is threadedly connected to the first lifting rod 11. When the threaded rod 13 rotates, it drives the first lifting rod 11 to slide along the inner wall of the mounting rod 10 through threaded transmission. At the same time, the lower end of the threaded tube 15 is threadedly connected to the second lifting rod 12. When the threaded tube 15 rotates, it drives the second lifting rod 12 to slide along the inner wall of the first lifting rod 11 through threaded transmission. Through the linkage between the threaded rod 13 and the threaded tube 15, the multi-level extension and retraction of the first lifting rod 11 and the second lifting rod 12 are realized, thereby adjusting the height of the mounting box 4, the plate frame 5 and the scraper 6, adapting to the cleaning needs of tanks of different depths, and solving the problems of limited adjustment range and insufficient adaptability of traditional single-stage lifting structures.
[0026] A lead screw 9 is rotatably installed inside the fixed frame 1. The lead screw 9 passes through the movable box 2 and is threadedly connected to the movable box 2. When the lead screw 9 inside the fixed frame 1 rotates, it drives the movable box 2 to slide horizontally along the fixed frame 1 through the threaded transmission with the movable box 2. The sliding of the movable box 2 can pull the installation rod 10, the first lifting rod 11, the second lifting rod 12, and the cleaning components such as the installation box 4 and the plate frame 5 to move synchronously along the radial direction of the tank. Combined with the adjustment of the height of the scraper 6 by the lifting structure and the adaptation of the angle of the scraper 6 by the angle adjustment mechanism 7, the scraper 6 can completely cover all areas of the tank from top to bottom and from center to edge. Whether it is radial wide-range cleaning of large-diameter tanks or axial long-distance cleaning of deep-cavity tanks, it can achieve cleaning operation without omissions or deviations, further enhancing the ability to clean without dead angles.
