Description

Technical Field

[0001] This utility model relates to the field of industrial dust treatment technology, specifically to a flow guiding device for a cyclone separator used in industrial dust treatment. Background Technology

[0002] Cyclone separators, as an important gas-solid separation device, are widely used in the field of industrial dust treatment. Their working principle is that the dust-laden airflow enters the cyclone separator through the inlet, forming an airflow rotating around its axis inside. Under the action of centrifugal force, the dust is thrown against the outer wall and downwards through the dust discharge port into the ash collection hopper, while the clean gas is discharged from the central outlet pipe.

[0003] The air entering the cyclone separator is mixed with large dust particles. These dust particles often rub against the guide vanes installed at the air inlet. The most common problem with cyclone separators is that the guide vanes are prone to wear. In the existing technology, there are many solutions to the wear of the guide vanes. Most of them add a removable protective shell to protect the guide vanes. Bolts or flanges are usually used for connection. Bolts or flanges are easily bent by large dust particles or become stuck with dust particles, making them difficult to disassemble. Protruding nuts and other parts are also easy to be covered with deposited sand and soil. Disassembly requires washing with water, which is extremely time-consuming and laborious.

[0024] 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.

[0025] 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.

[0026] Please see Figure 1-5 As shown, this utility model is a flow guiding device for a cyclone separator used in industrial dust treatment, comprising:

[0027] The fixed component includes a cyclone separator body, which includes a tank 10, an air inlet 11 welded to the upper side of the tank 10, a guide vane 12 threadedly fixed inside the air inlet 11, and an ash hopper 13 fixed to the lowest end of the tank 10.

[0028] The protective quick-release component includes a rubber pad 20 that is glued to one side of the guide vane 12, a protective liner 21 that is engaged with the other side of the rubber pad 20, and four fixing blocks 22 that are engaged with both ends of the guide vane 12. The fixing blocks 22 are located at the four corners of the guide vane 12.

[0029] Among the fixed components, the cyclone separator body is the basic frame of the entire device, the tank 10 is used to contain the airflow and dust separation process; the air inlet 11 is welded to the tank 10 and is the entrance for the dust-laden airflow; the guide vanes 12 are threaded and fixed inside the air inlet 11, which guide the airflow to form a stable vortex and improve the separation efficiency; the ash hopper 13 is fixed at the lowest end of the tank 10 and is used to collect the separated dust.

[0030] The inner sides of both ends of the protective liner 21 are fitted with the fixing blocks 22, and the inner side of the protective liner 21 is also fixed with rubber pads 20.

[0031] The inner sides of the protective liner 21 are fitted with the fixing blocks 22, and the inner side is fixed with rubber pads 20, which can resist the scouring and wear of dust on the guide vanes 12 and extend their service life. The rubber pads 20 play a buffering role and reduce the impact force.

[0032] The protective quick-release component also includes a first threaded hole 23 at both ends of the protective liner 21 and a second threaded hole 24 through both ends of the fixing block 22, with the first threaded hole 23 and the second threaded hole 24 being connected.

[0033] The first threaded hole 23 and the second threaded hole 24 are respectively opened on the protective liner 21 and the fixing block 22, and are connected in position, providing a channel for the long rod screw 25 to pass through and fix, so as to realize the fastening connection between the components of the protective quick-release component.

[0034] The protective quick-release component also includes a long rod screw 25 that passes through and fixes the first threaded hole 23 and the second threaded hole 24, a rotating port 26 at both ends of the long rod screw 25, and a soft plug 27 inserted in the second threaded hole 24.

[0035] The long screw 25 passes through the first threaded hole 23 and the second threaded hole 24, and firmly fixes the protective liner 21 and other components to the guide vane 12; the rotating port 26 makes it easy to use tools to tighten the long screw 25; the soft plug 27 is inserted into the second threaded hole 24 to prevent dust and other particles from entering the hole and thus avoid affecting the performance of the threaded connection.

[0036] Working principle: When the protective quick-release component is worn and needs to be replaced, simply wipe the outer surface of the fixing block 22 with a towel to expose the soft plug 27. Remove the soft plug 27 to expose the rotating port 26. Insert a tool into the rotating port 26 and rotate it to drive the long screw 25 to rotate, gradually disengaging the fixing block 22 and the protective liner 21. This allows for quick removal of the protective quick-release component on the guide vane 12. When replacing it, simply assemble the protective liner 21 and the fixing block 22 at the corresponding positions on the guide vane 12, then turn the long screw 25 into the first threaded hole 23 and the second threaded hole 24 to fix the protective quick-release component. Finally, insert the soft plug 27 into the second threaded hole 24 to complete the replacement.

[0037] This solution solves the problem of easy dust accumulation on components such as bolts or flanges, which makes disassembly inconvenient. It reduces the time required to replace the protective liner 21, saving a lot of time and preventing delays in work due to the replacement of the protective liner 21, thus reducing economic losses.

[0038] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, further includes:

[0039] The shock-absorbing component includes a retaining ring 30 threadedly fixed to one side of the rubber pad 20, a memory spring 31 fixed inside the retaining ring 30, and a protective sleeve 32 sleeved outside the retaining ring 30. The two ends of the protective sleeve 32 are fixed to the retaining rings 30 at both ends of the memory spring 31, and the memory spring 31 is located inside the protective sleeve 32.

[0040] In the shock-absorbing component, the retaining ring 30 is threaded onto one side of the rubber pad 20 for mounting and fixing the memory spring 31. The memory spring 31 is in a semi-compressed state, which can absorb the vibration caused by the airflow and reduce the vibration amplitude and frequency of the guide vane 12. At the same time, the spring itself will not affect the protective liner 21. The protective sleeve 32 is fitted on the outside of the retaining ring 30 and fixed at both ends to the retaining rings 30 at both ends of the memory spring 31. It can protect the memory spring 31 and prevent it from being corroded by dust and mechanically damaged.

[0041] Both ends of the memory spring 31 are provided with fixing rings 30. One fixing ring 30 is fixed to the rubber pad 20 on one side of the guide vane 12, and the other fixing ring 30 is threaded to the rubber pad 20 on the inner side of the protective liner 21.

[0042] This arrangement enables the memory spring 31 to form an elastic connection between the guide vane 12 and the protective liner 21, effectively transmitting and buffering vibrations.

[0043] Memory spring 31 is always in a semi-compressed state;

[0044] The compressed memory spring 31 is always capable of absorbing vibration energy, ensuring a continuous damping effect on the guide vane 12, and will not become unstable due to its own elasticity.

[0045] Working principle: When the guide vane 12 starts to guide the flow, the dust hits the protective liner 21. The force of the dust impact causes the protective liner 21 to vibrate. The transmitted force is transmitted to the compressed memory spring 31. The memory spring 31 cancels out the transmitted force. Since it is in a compressed state, it will not produce excessive shaking. At the same time, the fixed rubber pad 20 can absorb the noise generated by the dust impact while absorbing the excess vibration.

[0046] This solution absorbs the vibrations caused by dust impacts through the shock-absorbing components, preventing the long rod screw 25 from loosening due to vibration, which could lead to fatigue stress in the guide vane 12 and the interface, and long-term problems such as blade cracking, thus reducing the economic losses that would result.

[0047] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
