Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, specifically a vibration descaling mechanism for a cold slag machine cylinder. Background Technology

[0002] In coal-fired power plants, waste incineration plants and other fields, the high-temperature slag discharged from the boiler needs to be cooled to a treatable temperature (such as below 100°C) by a slag cooler, while ash and slag separation is achieved. However, the ash, minerals and other components contained in the high-temperature slag are very easy to form a dense and hard scale layer due to temperature gradient and material deposition during the cooling process on the surface of the slag cooler cylinder (and internal cooling components).

[0003] Currently, existing cold slag descaling methods have many drawbacks: manual descaling requires machine shutdown, is labor-intensive and inefficient, and does not completely remove scale. It also faces safety hazards such as high temperature and dust. Traditional mechanical scraping relies on fixed scrapers or scraping structures attached to spiral blades. When the scale layer is hard, it is easy to wear parts. The gap between the scraper and the cylinder is prone to slag accumulation. After long-term operation, the scraping effect drops sharply and may even scratch the cylinder. Chemical descaling requires the use of acid and alkali agents, which are costly and easily corrode equipment, and the generated waste liquid pollutes the environment. At the same time, the agents have poor stability under high temperature conditions, which severely limits their applicability.

[0004] Therefore, it is urgent to develop a high-efficiency, reliable, and easy-to-maintain cold slag machine cylinder vibration descaling mechanism. The purpose of this utility model is to provide a cold slag machine cylinder vibration descaling mechanism to solve the problems mentioned in the background art. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the technical problem of developing a vibration descaling mechanism for a cold slag mill cylinder as mentioned in the background art, the technical solution adopted by this utility model is as follows: The vibration descaling mechanism for a cold slag mill cylinder includes a cold slag mill cylinder, a descaling component, and a cooling component. A base is placed at the bottom of the cold slag mill cylinder, and an arch frame is fixed to the top of the base. The descaling component is installed at the top of the arch frame. The descaling component is detachably installed inside the cold slag mill cylinder and is used to break the scale layer adhering to the inner wall of the cold slag mill cylinder through mechanical vibration. The cooling component is connected to the cold slag mill cylinder and is used to cool the high-temperature slag inside the cold slag mill cylinder. The cooling component and the descaling component do not interfere with each other. Through the above structure, a collaborative architecture of the cold slag mill cylinder, the vibration descaling component, and the cooling component is realized, ensuring that the descaling function and the cooling function are independent and highly efficient and coordinated. This provides basic structural support for the stable operation of the entire mechanism. The synergistic effect ensures the descaling efficiency without affecting the cooling effect, and can adapt to the continuous operation requirements of the cold slag mill.

[0006] Preferably, the descaling component is a motor-driven structure, including a servo motor, a rotating shaft, and a descaling shovel. The servo motor is installed inside the cold slag machine cylinder, and the output end of the servo motor is rotatably connected to the rotating shaft. The end of the rotating shaft is fixedly connected to the descaling shovel. Through the above structure, the motor-driven mechanical descaling method is achieved directly and efficiently. The descaling shovel can cover a large area of ​​the inner wall of the cold slag machine cylinder as it rotates with the rotating shaft, which has a strong ability to destroy stubborn scale layers and good descaling coverage.

[0007] Preferably, the cooling assembly includes cooling pipes, spiral ridges, and cooling water pipes. The cooling pipes are arranged in layers along the axial direction of the slag cooler cylinder, with a slag drop gap between adjacent layers of cooling pipes. A cooling water pipe is provided at the top of each cooling pipe, and the inner wall of the cooling pipe is provided with spiral ridges to enhance the heat exchange efficiency between the cooling medium and the pipe wall. Through the above structure, the layered cooling pipes combined with the spiral ridges not only enhance the heat exchange efficiency between the cooling medium and the pipe wall to ensure rapid cooling of high-temperature slag, but also reduce the possibility of scaling on the inner wall of the cooling pipes through the spiral structure. The design of the slag drop gaps avoids slag accumulation and blockage, ensuring the long-term stable operation of the cooling system.

[0008] Preferably, a rotary adjuster is installed at the top of the base, and an adjustment frame is fixedly connected to the top of the base. The rotary adjuster and the adjustment frame are threaded together. Through the above structure, the adjustability of the mechanism is increased, and the position of the equipment posture components can be flexibly adjusted according to the characteristics of slag, the degree of scaling, etc., which improves the applicability of the mechanism to different working conditions and makes descaling more targeted.

[0009] Preferably, the side wall of the descaling shovel is fitted with a snap-fit ​​strip, and the end of the snap-fit ​​strip is fixed with an anti-wear strip, the shape of which fits the end of the descaling shovel. Through the above structure, the descaling shovel is protected to reduce direct wear and extend its service life, and the anti-wear strip can be quickly replaced by snap-fit ​​after wear, which is highly convenient for maintenance and reduces long-term use costs.

[0010] Preferably, the slag inlet end of the slag cooler cylinder is equipped with a detachable filter element, which is a circular mesh screen. Through the above structure, the circular mesh screen pre-treats the slag inlet, intercepts large foreign objects, and prevents them from entering the slag cooler cylinder and damaging the descaling components or clogging the cooling pipes. This effectively protects the internal structure, reduces the failure rate, and ensures the stable operation of the mechanism.

[0011] Preferably, an elastic bracket is fixed to the top of the arch frame, and the top of the elastic bracket is in contact with the descaling component. The elastic bracket is made of rubber, which reduces the noise during operation of the mechanism, reduces the damage of vibration to the arch frame, base and other supporting structures, and extends the service life of the overall mechanism.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The cold slag machine cylinder vibration descaling mechanism described in this utility model achieves a coordinated architecture of the cold slag machine cylinder, descaling components, and cooling components through the structural design of the cold slag machine cylinder. This ensures that the descaling and cooling functions are independent yet highly coordinated, providing basic structural support for the stable operation of the entire mechanism. The coordinated effect ensures descaling efficiency without affecting the cooling effect, and can adapt to the continuous operation requirements of the cold slag machine.

[0014] 2. The cold slag machine cylinder vibration descaling mechanism described in this utility model achieves direct and efficient mechanical descaling through the structural arrangement of a servo motor and a descaling shovel. The descaling shovel can cover a large area of ​​the inner wall of the cold slag machine cylinder as it rotates with the shaft, which has a strong ability to destroy stubborn scale layers and good descaling coverage.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] like Figure 1As shown in the embodiment of this utility model, a cold slag mill cylinder vibration descaling mechanism includes a cold slag mill cylinder 1, a descaling component, and a cooling component. A base 11 is placed at the bottom of the cold slag mill cylinder 1, and an arch frame 12 is fixed to the top of the base 11. The descaling component is installed at the top of the arch frame 12. The descaling component is detachably installed inside the cold slag mill cylinder 1 and is used to break the scale layer attached to the inner wall of the cold slag mill cylinder 1 through mechanical vibration. The cooling component is connected to the cold slag mill cylinder 1 and is used to cool the high-temperature slag inside the cold slag mill cylinder 1. The cooling component and the descaling component do not interfere with each other. During operation, the bottom of the slag cooler cylinder 1 is placed on the base 11, and the arch frame 12 fixed to the top of the base 11 is used to support the descaling component. The descaling component can be detachably installed inside the slag cooler cylinder 1 and breaks the scale layer attached to the inner wall of the cylinder through mechanical vibration. The cooling component is connected to the slag cooler cylinder 1 to cool the high-temperature slag inside the cylinder. The spatial layout of the cooling component and the descaling component do not interfere with each other and they operate independently. Through the above structure, the overall structural layout is stable. The descaling function and the cooling function are independent of each other to avoid functional interference, and they work together to ensure the descaling efficiency without affecting the cooling effect, which can meet the continuous operation requirements of the slag cooler.

[0024] like Figure 3 As shown, the descaling assembly is a motor-driven structure, including a servo motor 2, a rotating shaft 21, and a descaling shovel 22. The servo motor 2 is installed inside the cold slag machine cylinder 1. The output end of the servo motor 2 is rotatably connected to the rotating shaft 21, and the end of the rotating shaft 21 is fixedly connected to the descaling shovel 22. During operation, the servo motor 2 is installed inside the cold slag machine cylinder 1. After the servo motor 2 is started, its output end drives the rotating shaft 21 to rotate. The descaling shovel 22 fixedly connected to the end of the rotating shaft 21 rotates synchronously with the rotating shaft. The scale layer on the inner wall of the cold slag machine cylinder 1 is scraped off through mechanical contact and vibration. With the above structure, the motor-driven mechanical descaling method is direct and efficient. The descaling shovel 22 can cover a large area of ​​the inner wall of the cold slag machine cylinder 1 as it rotates with the rotating shaft 21. It has a strong ability to destroy stubborn scale layers and good descaling coverage.

[0025] like Figure 3As shown, the cooling assembly includes cooling pipes 3, spiral ribs 31, and cooling water pipes 32. The cooling pipes 3 are arranged in layers along the axial direction of the slag cooler cylinder 1, with a slag drop gap between adjacent layers of cooling pipes 3. Cooling water pipes 32 are located at the top of each cooling pipe 3. The inner wall of each cooling pipe 3 has spiral ribs 31 to enhance the heat exchange efficiency between the cooling medium and the pipe wall. During operation, the cooling pipes 3 are arranged in layers along the axial direction of the slag cooler cylinder 1, with a slag drop gap between adjacent layers of cooling pipes 3. The cooling medium enters the cooling pipe 3 from the cooling water pipe 32. The spiral ridges 31 on the inner wall of the cooling pipe 3 increase the contact area between the cooling medium and the pipe wall, enhance the turbulence of the medium, and improve the heat exchange efficiency. Through the above structure, the layered cooling pipe 3 combined with the spiral ridges 31 not only enhances the heat exchange efficiency between the cooling medium and the pipe wall to ensure rapid cooling of high-temperature slag, but also reduces the possibility of scaling on the inner wall of the cooling pipe through the spiral structure. The design of the slag drop gap avoids slag accumulation and blockage, ensuring the long-term stable operation of the cooling system.

[0026] like Figures 1 to 4 As shown, a rotary adjuster 4 is installed at the top of the base 11, and an adjustment frame 41 is fixedly connected to the top of the base 11. The rotary adjuster 4 and the adjustment frame 41 are threaded together. During operation, the relative position angle between the base 11 and related components can be adjusted by rotating the rotary adjuster 4, thereby adjusting the posture of the cold slag machine cylinder 1 or the position of the descaling components. After descaling is completed, the cold slag machine cylinder 1 is tilted to allow the internal descaling to accumulate. Through the above structure, the adjustability of the mechanism is increased, and the position of the equipment posture components can be flexibly adjusted according to the characteristics of the slag and the degree of scaling, which improves the applicability of the mechanism to different working conditions and makes descaling more targeted.

[0027] like Figure 4 As shown, a snap-fit ​​strip 5 is snapped onto the side wall of the descaling shovel 22, and an anti-wear strip 51 is fixedly attached to the end of the snap-fit ​​strip 5. The shape of the anti-wear strip 51 fits the end of the descaling shovel 22. During operation, the snap-fit ​​strip 5 is installed on the side wall of the descaling shovel 22 by snap-fit, and the anti-wear strip 51 is fixedly attached to the end of the snap-fit ​​strip 5. The shape of the anti-wear strip 51 fits the end contour of the descaling shovel 22. During descaling, the anti-wear strip 51 directly contacts the inner wall of the cold slag machine cylinder 1, reducing the wear of the descaling shovel 22. Through the above structure, the descaling shovel 22 is protected from direct wear and its service life is extended. It can also be quickly replaced by snap-fit ​​after the anti-wear strip 51 is worn, which is convenient for maintenance and reduces long-term use costs.

[0028] like Figure 3As shown, the slag inlet end of the slag cooler cylinder 1 is equipped with a detachable filter element, which is a circular mesh screen 6. During operation, before the slag enters the cylinder, the circular mesh screen 6 intercepts large foreign objects such as unburned large slag deposits and castable fragments. Through the above structure, the circular mesh screen 6 pre-treats the incoming slag, intercepts large foreign objects, and prevents them from entering the slag cooler cylinder 1 and damaging the descaling components or clogging the cooling pipes. This effectively protects the internal structure, reduces the failure rate, and ensures the stable operation of the mechanism.

[0029] like Figure 1 As shown, an elastic bracket 7 is fixed to the top of the arch frame 12. The top of the elastic bracket 7 is in contact with the descaling component. The elastic bracket 7 is made of rubber. During operation, when the descaling component vibrates, the elastic bracket 7 can buffer the vibration impact force and reduce the transmission of vibration to the arch frame 12 and the base 11. Through the above structure, the noise during the operation of the mechanism is reduced, the damage of vibration to the supporting structures such as the arch frame 12 and the base 11 is reduced, and the service life of the overall mechanism is extended.

[0030] During operation, the bottom of the slag cooler cylinder 1 rests on the base 11, and the arch frame 12 fixed to the top of the base 11 supports the descaling component. The descaling component is detachably installed inside the slag cooler cylinder 1 and breaks down the scale layer adhering to the inner wall of the cylinder through mechanical vibration. The cooling component is connected to the slag cooler cylinder 1 to cool the high-temperature slag inside the cylinder. The spatial layout of the cooling component and the descaling component is independent and they operate independently. Through the above structure, the overall structural layout is stable. The descaling function and the cooling function are independent to avoid functional interference, and they work together to ensure descaling efficiency without affecting cooling. The system is effective and adaptable to the continuous operation requirements of the slag cooler. The servo motor 2 is installed inside the slag cooler cylinder 1. After starting the servo motor 2, its output drives the rotating shaft 21 to rotate. The descaling scraper 22, fixed to the end of the rotating shaft 21, rotates synchronously with the shaft, scraping away the scale layer on the inner wall of the slag cooler cylinder 1 through mechanical contact and vibration. Through this structure, the motor-driven mechanical descaling method is direct and efficient. The descaling scraper 22, rotating with the rotating shaft 21, can cover a large area of ​​the inner wall of the slag cooler cylinder 1, exhibiting strong destructive power against stubborn scale layers and good comprehensive descaling. The cooling pipes 3 are arranged in layers along the axial direction of the slag cooler cylinder 1, with adjacent layers of cooling pipes... A slag drop gap is reserved between the cooling pipes 3 and 3. The cooling medium enters the cooling pipe 3 from the cooling water pipe 32. The spiral ridges 31 on the inner wall of the cooling pipe 3 increase the contact area between the cooling medium and the pipe wall, enhance the turbulence of the medium, and improve the heat exchange efficiency. Through the above structure, the layered arrangement of the cooling pipes 3 combined with the spiral ridges 31 not only enhances the heat exchange efficiency between the cooling medium and the pipe wall to ensure rapid cooling of high-temperature slag, but also reduces the possibility of scaling on the inner wall of the cooling pipe through the spiral structure. The design of the slag drop gap avoids slag accumulation and blockage, ensuring the long-term stable operation of the cooling system. By rotating the rotary regulator 4, the slag drop gap can be adjusted. Adjust the relative position angle between the base 11 and related components, thereby adjusting the posture of the cold slag machine cylinder 1 or the position of the descaling components. After descaling is completed, tilt the cold slag machine cylinder 1 to allow the internal descaling to accumulate. Through the above structure, the adjustability of the mechanism is increased. The position of the equipment posture components can be flexibly adjusted according to the characteristics of the slag and the degree of scaling, which improves the applicability of the mechanism to different working conditions and makes descaling more targeted. The side wall of the descaling shovel 22 is fitted with a snap-fit ​​strip 5 by snap-fitting. The end of the snap-fit ​​strip 5 is fixed with an anti-wear strip 51, and the shape of the anti-wear strip 51 fits the end contour of the descaling shovel 22.During descaling, the anti-wear strip 51 directly contacts the inner wall of the cold slag machine cylinder 1, reducing the wear of the descaling shovel 22. This structure protects the descaling shovel 22, reducing direct wear and extending its service life. It also allows for quick replacement of the anti-wear strip 51 after wear, providing high maintenance convenience and reducing long-term operating costs. Before the slag enters the cylinder, the circular screen 6 intercepts large foreign objects such as unburned slag and castable fragments. This structure pre-treats the incoming slag, intercepting large foreign objects and preventing them from entering the cold slag machine cylinder 1 and damaging the descaling components or clogging the cooling pipes. This effectively protects the internal structure, reduces the failure rate, and ensures stable operation. When the descaling components vibrate during operation, the elastic support 7 buffers the vibration impact, reducing the transmission of vibration to the arch frame 12 and base 11. This structure reduces noise during operation and minimizes damage to the arch frame 12, base 11, and other supporting structures, extending the overall service life of the mechanism.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
