Description

Technical Field

[0001] This utility model relates to the technical field of boiler cleaning devices, specifically a device for tightening metal hoses in hydraulic ash removal systems. Background Technology

[0002] In the field of waste-to-energy incineration, waste heat boilers are often equipped with hydraulic ash removal systems to remove ash buildup in the flue and ensure boiler operating efficiency. The core of this system lies in the use of a retractable metal hose to deliver high-pressure cleaning water into the flue. In non-operating conditions, this metal hose is coiled within the cleaning unit mounted above the boiler's main beam; when the cleaning system is running, the metal hose must be precisely inserted into the flue, and water jets are sprayed out through nozzles at its end to complete the ash removal.

[0003] Whether the metal flexible hose can extend safely and smoothly from the main unit and accurately enter the flue, and whether it can be completely and orderly retracted into the main unit after the system has finished operating, are the key factors determining the success or failure of the entire hydraulic cleaning system.

[0004] However, in practical applications, manufacturing tolerances of the metal hose and fluctuations in internal water pressure can cause dynamic changes in its outer diameter. This change directly affects the friction between the metal hose and the drive wheel, which is the sole power source for driving the hose's extension and retraction.

[0005] Excessive friction can cause a surge in drive load, which may not only overload the drive system but also rapidly accelerate the wear of the metal hose and drive wheel, shortening the equipment's lifespan.

[0006] If the friction is too low, the drive will slip, causing the metal hose to be unable to extend or retract normally, resulting in problems such as jamming and disordered arrangement, which will cause the dust removal system to fail.

[0007] Based on this, our company has specially designed and manufactured a metal hose clamping device that can automatically adjust the clamping force between the clamping device and the drive wheel according to the change of the outer diameter of the metal hose. Utility Model Content

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure will not be enlarged to scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0033] This invention provides a device specifically for tightening metal hoses in hydraulic cleaning systems. By adjusting the preload of the tension spring, the pressure of the rollers and drive wheels on the metal hose can be precisely controlled, thereby stabilizing the friction between the metal hose and the drive wheel within the optimal range.

[0034] Figures 1-3 The diagram shown is a structural schematic of one embodiment of a device for clamping metal hoses in a hydraulic cleaning system according to this utility model. Please refer to [link / reference]. Figures 1-3 This embodiment provides a device specifically for tightening metal hoses in hydraulic cleaning systems. Its main body includes a bracket 100, rollers 2, tension springs 5, drive wheels 7, and metal hoses 8.

[0035] The bracket 100, composed of side plates and positioning posts 4, and the sliding groove 11 facilitate the movement of the wheel axle 3. Its stroke is determined by the extension and contraction of the tension spring 5. By adjusting the preload of the tension spring 5, the pressure of the roller 2 and the drive wheel 7 on the metal hose 8 can be precisely controlled, thereby stabilizing the friction between the metal hose 8 and the drive wheel 7 within the optimal range. The setting of the pressure roller 6 ensures the dynamic balance and synchronization of the roller 2 and the drive wheel 7 during the pressing process. Specifically, the side wall of the bracket 100 is provided with a sliding groove 11. In this embodiment, the bracket 100 is composed of two side plates arranged opposite each other, with a positioning post 4 between the side plates. The pressure roller 6 is provided on the lower side of the bracket 100, and the pressure roller 6 rolls close to the inner edge of the drive wheel 7.

[0036] The minimum number of rollers 2 is 3, and a three-roller 2 parallel layout is adopted to form system redundancy. In the extreme case of accidental failure of a single roller 2, the other two rollers 2 can temporarily maintain the necessary clamping force on the drive wheel 7 by adjusting the pressure of the tension spring 5, thereby ensuring that the system continues to operate stably for a short time without stopping the machine, which significantly improves the fault tolerance and operational reliability of the equipment. Specifically, the shaft of the roller 2 is provided with a wheel axle 3 that moves along the slide groove 11. In this embodiment, the side wall of the wheel axle 3 is provided with a plane that moves along the slide groove 11. Limit heads are respectively provided at both ends of the wheel axle 3. The shaft of the roller 2 is provided with a bearing 21, and the inner ring of the bearing 21 is interference-fitted with the outer ring of the wheel axle 3.

[0037] The tension spring 5 provides flexible pressure. Specifically, one end of the tension spring 5 pulls the wheel axle 3, and the other end is fixedly connected to the side wall of the bracket 100. In this embodiment, the top of the tension spring 5 is provided with a hook that hooks onto the end of the wheel axle 3, and the bottom of the pull rope spring is provided with a hook that hooks onto the end of the positioning post 4 on the lower side of the bracket 100.

[0038] The drive wheel 7 is controlled to rotate by a motor and uses friction to transmit the metal hose 8. Specifically, the drive wheel 7 is set on the side wall of the bracket 100 and cooperates with the roller 2. In this embodiment, a drive shaft is set on the lower side of the bracket 100, and the drive wheel 7 is set on the outer periphery of the drive shaft.

[0039] The metal hose 8 passes between the roller 2 and the drive wheel 7.

[0040] Combination Figures 1-3 This embodiment describes a device specifically designed for clamping metal hoses in a hydraulic cleaning system. The specific operation is as follows: By adjusting the preload of the tension spring 5, the pressure of the rollers 2 and drive wheel 7 on the metal hose 8 can be precisely controlled, thereby stabilizing the friction between the metal hose 8 and the drive wheel 7 within an optimal range. The pressure roller 6 ensures dynamic balance and synchronization between the rollers 2 and drive wheel 7 during the clamping process. A minimum of three rollers 2 are used, arranged in a parallel configuration to create system redundancy. In extreme cases where a single roller 2 fails unexpectedly, the remaining two rollers 2 can temporarily maintain the necessary clamping force on the drive wheel 7 by adjusting the pressure of the tension spring 5, thus ensuring the system continues to operate stably for a short period without shutting down the system. This significantly improves the equipment's fault tolerance and operational reliability. The drive wheel 7 rotates under motor control, using friction to transmit the metal hose 8.

[0041] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
