Description

Technical Field

[0001] This utility model relates to tobacco processing equipment, and more particularly to a cleaning device for a dehumidification screen of a rehumidifier. Background Technology

[0002] In the tobacco processing production process, the stem rehumidifier is a key piece of equipment for increasing the temperature and humidity of tobacco stem materials. Its working principle is to heat and rehumidify the tobacco stems with steam. Excess steam needs to be filtered through a dehumidification screen before being discharged to maintain the internal pressure balance and process parameters of the equipment.

[0003] However, existing dehumidification machine screen cleaning technology has significant flaws, leading to frequent screen clogging problems. This not only affects production continuity but also poses quality and safety hazards. Specifically, during the preheating stage of the rehumidification machine, the equipment needs to be heated to the set temperature. However, at this time, no tobacco stem material has absorbed steam, and excess steam should be discharged through the dehumidification screen. However, when the screen becomes clogged, the steam cannot be effectively discharged and is forced to accumulate inside the cylinder and overflow at both ends, forming a large amount of condensate at the front and rear ends of the rehumidification machine. This phenomenon not only causes the temperature and humidity parameters inside the cylinder to fail to meet process requirements, affecting the uniformity of tobacco stem rehumidification quality, but also causes water accumulation in the surrounding area of ​​the equipment, increasing the safety risk of water ingress and leakage into electrical equipment.

[0004] Therefore, there is an urgent need to design a dehumidification screen cleaning device for rehumidifiers to solve the above technical problems. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0042] This embodiment provides a cleaning device for the dehumidification screen of a rehumidification machine, which can effectively solve the problem of screen blockage, improve production efficiency and product yield, and reduce safety hazards.

[0043] like Figures 1-6As shown, the dehumidification screen cleaning device of the rehumidification machine mainly includes a brush shaft 10, a brush roller 20, and at least one set of brush assemblies 30. The two ends of the brush shaft 10 are used for mounting on the frame. The brush roller 20 is sleeved on and connected to the brush shaft 10, and a mounting groove 21 is provided on the outer periphery of the brush roller 20. The brush assembly 30 includes a base 31, a brush screw 32, and a V-shaped brush 33. The V-shaped brush 33 is spirally wound on the brush screw 32, and the brush screw 32 is embedded in the base 31. The base 31 is detachably connected to the mounting groove 21.

[0044] Based on the above design, in this embodiment, a brush assembly 30 is provided, consisting of a brush shaft 10, a brush roller 20, and at least one set of brush components 30, including a base 31, a brush screw 32, and a V-shaped brush 33. The brush assembly 30 is detachably connected to the brush roller 20, allowing for quick replacement when the brush assembly 30 is damaged, reducing maintenance time and costs. Specifically, the brush assembly 30 is detachably connected to the mounting groove 21 via the base 31, facilitating quick replacement of worn V-shaped brushes 33, reducing downtime for maintenance, and improving work efficiency. The V-shaped brush 33 is spirally wound around the brush screw 32, causing it to make multi-angle contact with the dehumidifier's screen during rotation. This increases the cleaning coverage area, effectively removing dust and debris from the dehumidifier's screen, preventing clogging, ensuring smooth dehumidification, avoiding steam overflow and condensate accumulation, eliminating safety hazards, and improving production efficiency and product quality.

[0045] like Figures 5-6 As shown, the base 31 has a trapezoidal cross-section, and an opening is provided on one side of the base 31, which is configured to press in the brush screw 32. This structural design enhances the fixing effect of the base 31 on the brush screw 32, ensures the stability of the brush assembly 30 during high-speed rotation and friction with the screen, prevents the brush screw 32 from loosening, and thus improves the reliability and durability of the dehumidification screen cleaning device of the dehumidifier.

[0046] For example, the angle of the bevel of the base 31 can be designed to be 5°-15° to ensure that sufficient friction is generated under centrifugal force.

[0047] Furthermore, the brush assembly 30 includes multiple V-shaped brushes 33, which are arranged in a straight line along the axial direction of the brush roller 20, greatly enhancing the cleaning power and cleaning range. Multiple V-shaped brushes simultaneously contact the screen, enabling more effective removal of debris from the screen, improving cleaning efficiency, ensuring the smooth flow of the dehumidification screen, and thus ensuring the normal operation of the dehumidifier.

[0048] The axial linear arrangement ensures that the V-shaped brushes 33 are subjected to uniform force during rotation, reducing localized wear and extending service life. For example, the bristle spacing between adjacent V-shaped brushes 33 can be designed to be 2mm-3mm to avoid the V-shaped brushes 33 from being squeezed and deformed due to excessively small spacing.

[0049] In some alternative implementations, adjacent V-shaped brushes 33 may be arranged in an alternating manner, that is, the bristles of the later V-shaped brush 33 are inserted into the gaps of the earlier V-shaped brush 33 to form a denser cleaning area.

[0050] For example, the number of brush assemblies 30 can be adjusted according to the width of the screen. For example, for a screen with a width of 1m, 8 to 10 sets of brush assemblies 30 can be set.

[0051] Optionally, the V-shaped brush 33 in this embodiment is made of stainless steel. The stainless steel V-shaped brush 33 can withstand the high temperature and humidity environment inside the dehumidifier, preventing rust and deformation. For example, in a steam environment of 80℃-100℃, the lifespan of the stainless steel V-shaped brush 33 is 3-5 times longer than that of ordinary plastic brushes. At the same time, the stainless steel bristles have high hardness and toughness, effectively removing stubborn impurities from the screen surface while reducing their own wear.

[0052] Optionally, the diameter of the V-shaped brush 33 can be adjusted according to the mesh size of the screen. For example, for a screen with a mesh diameter of 2mm-3mm, stainless steel brush bristles with a diameter of 0.3mm-0.5mm can be selected.

[0053] In this embodiment, bearings (not shown in the figure) are provided at both ends of the brush shaft 10, and the bearings are used to connect to the frame; such as Figure 4 As shown, the brush shaft 10 is also provided with a first threaded hole 11. The dehumidifier screen cleaning device also includes a first fixing member (not shown in the figure). The first fixing member passes through the first threaded hole 11 and is used to connect the brush shaft 10 and the brush roller 20.

[0054] The bearing design allows the brush shaft 10 to rotate smoothly and connects it to the frame, providing stable support for the entire cleaning device. The engagement of the first threaded hole 11 and the first fixing member ensures a tight connection between the brush shaft 10 and the brush roller 20, guaranteeing that the brush shaft 10 rotates in tandem with the brush roller 20. When the brush roller 20 needs replacement or repair, simply unscrewing the first fixing member allows for easy and quick removal from the brush shaft 10. For example, in actual maintenance, if the brush roller 20 is found to be damaged, this connection method allows for rapid replacement, minimizing downtime.

[0055] In this embodiment, the brush roller 20 is cylindrical, and its inner hole is tightly fitted with the brush shaft 10. The first fixing member passes through the inner hole of the brush roller 20 and connects with the first threaded hole 11 on the brush shaft 10 to achieve a fixed connection between the brush roller 20 and the brush shaft 10.

[0056] For example, the bearing can be a sealed bearing to prevent steam and dust from entering and extend bearing life. The first fastener can be an internal hex head screw for easy tightening with tools to ensure a secure connection.

[0057] like Figures 1-3 As shown, the dehumidifier screen cleaning device in this embodiment also includes a fixing component 40. The fixing component 40 is disposed at both ends of the brush roller 20. The fixing component 40 is configured to fix the brush roller 20 and the brush assembly 30 on the brush shaft 10, effectively preventing the brush roller 20 from axial movement and radial shaking when rotating.

[0058] Specifically, the fixing component 40 in this embodiment includes a locking ring 41 and a second fixing member (not shown in the figure). The end face of the locking ring 41 has a second threaded hole 411, and the second fixing member passes through the second threaded hole 411 and is used to connect the locking ring 41 and the brush roller 20. The locking ring 41 is installed at the end of the brush roller 20, and the second threaded hole 411 on it cooperates with the second fixing member to firmly fix the brush roller 20 on the brush shaft 10. When the cleaning device rotates, the locking ring 41 can withstand the axial force generated by the brush roller 20 and prevent the brush roller 20 from moving on the brush shaft 10. For example, when the brush roller 20 rotates at high speed and is subjected to the reaction force of the screen, the locking ring 41 firmly fixes the brush roller 20 on the brush shaft 10 through the second fixing member, ensuring that there is no relative displacement between the brush roller 20 and the brush shaft 10, thereby ensuring the normal operation of the cleaning device.

[0059] For example, the second fastener can be a bolt or screw. Furthermore, the multiple second threaded holes 411 on the end face of the locking ring 41 are evenly distributed, enabling the second fastener to uniformly transmit axial force when connecting the locking ring 41 and the brush roller 20, preventing the brush roller 20 from deforming or being damaged due to uneven force distribution.

[0060] Furthermore, the fixing component 40 in this embodiment also includes a locking ring 42, a third fixing member, and a fourth fixing member (not shown in the figure). The locking ring 42 has a third threaded hole 421 on its side and a fourth threaded hole 422 on its end face. The third fixing member passes through the third threaded hole 421 and is used to connect circumferentially with the brush shaft 10. The fourth fixing member passes through the fourth threaded hole 422 and is used to connect with the locking ring 41.

[0061] The locking ring 42 is mounted on the brush shaft 10 and is circumferentially connected to the brush shaft 10 via a third fixing member, preventing relative rotation between the brush shaft 10 and the locking ring 42. Simultaneously, the locking ring 42 is connected to the locking ring 41 via a fourth fixing member, tightly securing the locking ring 41 to the brush shaft 10. This structure forms a robust whole between the brush shaft 10, locking ring 42, locking ring 41, and brush roller 20, capable of withstanding greater torque and axial force. For example, during the cleaning process, when the brush assembly 30 is subjected to the reaction torque of the screen, the connection between the locking ring 42 and the locking ring 41 effectively prevents relative rotation between the brush roller 20 and the brush shaft 10, ensuring that all components work closely together under complex working conditions without relative rotation or displacement, thus improving the reliability and stability of the dehumidifying screen cleaning device for the rehumidifier.

[0062] For example, the third and fourth fasteners can be bolts or screws. The multiple third threaded holes 421 and multiple fourth threaded holes 422 on the side and end faces of the locking ring 42 are evenly distributed, making the connection between the locking ring 42 and the brush shaft 10 and the locking ring 41 more secure, while avoiding localized stress concentration and improving the stability and load-bearing capacity of the entire connection structure.

[0063] The dehumidifier screen cleaning device in this embodiment also includes a motor and a coupling (not shown in the figure). The output end of the motor is connected to the coupling, and the coupling is connected to one end of the brush shaft 10 so that the motor drives the brush shaft 10 to rotate.

[0064] Specifically, the motor acts as the power source, transmitting power to the brush shaft 10 via a coupling, which in turn drives the dehumidifier screen cleaning device to rotate. This method allows for precise control of the device's speed and operating time, achieving a highly efficient and stable cleaning process. Compared to traditional manual cleaning methods, the automated dehumidifier screen cleaning device can operate continuously for extended periods, resulting in more uniform and consistent cleaning. For example, during production, simply starting the motor allows the device to automatically clean the screen without manual intervention, significantly improving production efficiency and avoiding potential errors and safety hazards associated with manual operation.

[0065] For example, a variable frequency speed control motor can be selected, with a speed range of 50rpm-300rpm, to adapt to cleaning needs under different working conditions. The coupling can be a plum blossom-shaped flexible coupling, whose elastic element is made of polyurethane material, which has good buffering and vibration damping performance.
