Abstract
Description
Technical Field
[0001] This utility model relates to the field of medium-frequency furnaces, specifically a furnace cleaning device for medium-frequency furnaces that is easy to operate. Background Technology
[0002] An intermediate frequency furnace is an industrial device that uses the principle of electromagnetic induction to heat or melt metals. Its operating frequency is usually in the intermediate frequency range. The core principle is to generate eddy currents inside the metal through alternating current, thereby achieving efficient and precise heating or melting. The intermediate frequency furnace cleaning device is a special device used to remove residual slag, oxide scale and scale inside the furnace. It is crucial for maintaining furnace performance, extending service life and improving smelting efficiency.
[0003] In existing technologies, furnace cleaning typically involves spraying high-pressure gas to flush the furnace. Cleaning usually requires personnel to hold the nozzle by hand. Existing medium-frequency furnace cleaning devices do not allow for automatic movement of the nozzle to different locations for cleaning, reducing the convenience of using the cleaning device. In addition, large medium-frequency furnaces have a large internal space, and existing medium-frequency furnace cleaning devices do not allow for rotating the nozzle while spraying high-pressure gas, which can easily create blind spots and reduce the cleaning effect. Utility Model Content
[0004] To overcome the shortcomings of existing technologies and solve the problems of inconvenience in automatically moving the nozzle to different positions for cleaning and inconvenience in rotating the nozzle while spraying high-pressure gas, this utility model proposes an easy-to-operate medium-frequency furnace cleaning device.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The present utility model provides an easy-to-operate medium-frequency furnace cleaning device, including a frame plate, a through hole in the middle of the top of the frame plate, a lifting component rotatably connected to the surface of the through hole, an upper fixing ring fixedly connected to the bottom of the lifting component, a connecting rod fixedly connected in a ring array at the bottom edge of the upper fixing ring, a lower fixing ring fixedly connected to the bottom of the connecting rod, and a cleaning component fixedly connected to the inner surface of the lower fixing ring. The lifting assembly includes a threaded rod rotatably connected to the surface of a through hole, a transmission rod fixedly connected to the top of the threaded rod, a splined connection of the top of the transmission rod to the output end of a servo motor, a threaded cylinder threadedly connected to the surface of the threaded rod, an upper fixing ring fixedly connected to the surface of the threaded cylinder, and an upper fixing ring fixedly connected to the bottom of the threaded cylinder. The cleaning component includes a connecting cylinder fixedly connected to the inner surface of the lower fixing ring, a conical cylinder rotatably connected to the bottom of the connecting cylinder, a pressurized nozzle arranged in a ring array at the bottom of the conical cylinder, and a guide plate fixedly connected to the inner surface of the conical cylinder.
[0006] Preferably, a base plate is fixedly connected to the bottom of the frame plate, and a caster wheel is fixedly connected to the bottom edge of the base plate.
[0007] Preferably, a limiting plate is slidably connected to the surface of the threaded cylinder, and frame plates are fixedly connected to both ends of the limiting plate.
[0008] Preferably, a limiting cylinder is fixedly connected to the middle of the top of the frame plate, and a threaded rod is rotatably connected to the inner surface of the limiting cylinder.
[0009] Preferably, a motor box is fixedly connected to the top of the limiting cylinder, and a servo motor is fixedly connected to the inner surface of the motor box.
[0010] Preferably, the top of the connecting cylinder is threaded with a threaded connector, and the top of the threaded connector is connected through a gas supply pipe.
[0011] The advantages of this utility model are: 1. This utility model, through the structural design of the lifting component, delivers high-pressure airflow to the cleaning component through the gas supply pipe when using the cleaning device to clean the furnace. At the same time, the servo motor is connected to the power supply and powered on, causing the transmission rod to drive the threaded rod to rotate. The threaded rod pushes the threaded cylinder to slowly descend, thereby causing the cleaning component to move slowly during the process of spraying high-pressure gas for cleaning. This allows the medium-frequency furnace cleaning device to automatically move the nozzle to different positions for cleaning, improving the convenience of using the cleaning device. 2. Through the structural design of the cleaning components, this utility model allows for the cleaning of the furnace by delivering high-pressure airflow through the gas supply pipe to the connecting cylinder. After being guided by the guide plate, the high-pressure airflow is ejected from the booster nozzle to clean the furnace. The impact of the high-pressure airflow on the guide plate creates a component force on the inclined surface of the guide plate that drives the conical cylinder to rotate, thereby causing the booster nozzle to rotate during the jetting process. This avoids blind spots in cleaning while improving the cleaning effect. Attached Figure Description

[0015] 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 scope of protection of the present utility model.
[0016] Please see Figures 1-4 As shown, an easy-to-operate medium-frequency furnace cleaning device includes a frame plate 1. A through hole is provided in the middle of the top of the frame plate 1. A lifting component 2 is rotatably connected to the surface of the through hole. An upper fixing ring 3 is fixedly connected to the bottom of the lifting component 2. A connecting rod 4 is fixedly connected in a ring array at the bottom edge of the upper fixing ring 3. A lower fixing ring 5 is fixedly connected to the bottom of the connecting rod 4. A cleaning component 6 is fixedly connected to the inner surface of the lower fixing ring 5. The lifting assembly 2 includes a threaded rod 201 rotatably connected to the surface of the through hole, a transmission rod 202 fixedly connected to the top of the threaded rod 201, a splined connection of the top of the transmission rod 202 to the output end of the servo motor 203, a threaded cylinder 204 threadedly connected to the surface of the threaded rod 201, an upper fixing ring 3 fixedly connected to the surface of the threaded cylinder 204, and an upper fixing ring 3 fixedly connected to the bottom of the threaded cylinder 204. The cleaning component 6 includes a connecting cylinder 601 fixedly connected to the inner surface of the lower fixing ring 5, a conical cylinder 602 rotatably connected to the bottom of the connecting cylinder 601, a pressurizing nozzle 603 arranged in a ring array at the bottom of the conical cylinder 602, and a guide plate 604 fixedly connected to the inner surface of the conical cylinder 602. During operation, the lifting component 2, through its structural design, delivers high-pressure airflow to the cleaning component 6 via the gas supply pipe 13 when cleaning the furnace. Simultaneously, the servo motor 203 is connected to the power supply, causing the transmission rod 202 to drive the threaded rod 201 to rotate. This, in turn, pushes the threaded cylinder 204 to descend slowly, allowing the cleaning component 6 to move slowly during the high-pressure gas cleaning process. This enables the medium-frequency furnace cleaning device to automatically move the nozzle to different positions for cleaning, improving the convenience of using the cleaning device. The cleaning component 6, through its structural design, delivers high-pressure airflow to the connecting cylinder 601 via the gas supply pipe 13 when cleaning the furnace. After impacting the guide plate 604 and being guided, the high-pressure airflow is ejected from the pressurized nozzle 603 to clean the furnace. The impact of the high-pressure airflow on the guide plate 604 creates a component force on the inclined surface of the guide plate 604 that pushes the conical cylinder 602 to rotate, causing the pressurized nozzle 603 to rotate during the jetting process. This avoids blind spots in cleaning while improving the cleaning effect.
[0017] Furthermore, a base plate 7 is fixedly connected to the bottom of the frame plate 1, and a caster wheel 8 is fixedly connected to the bottom edge of the base plate 7; During operation, the mobility of the equipment is improved by the base plate 7 and the casters 8.
[0018] Furthermore, a limiting plate 9 is slidably connected to the surface of the threaded cylinder 204, and frame plates 1 are fixedly connected to both ends of the limiting plate 9; During operation, the rotation of the threaded cylinder 204 is restricted by the setting of the limiting plate 9, preventing the threaded rod 201 from driving the threaded cylinder 204 to rotate together.
[0019] Furthermore, a limiting cylinder 10 is fixedly connected to the middle of the top of the frame plate 1, and a threaded rod 201 is rotatably connected to the inner surface of the limiting cylinder 10. During operation, the limiting sleeve 10 provides additional lateral support to the threaded rod 201, preventing it from shaking when rotating.
[0020] Furthermore, a motor box 11 is fixedly connected to the top of the limiting cylinder 10, and a servo motor 203 is fixedly connected to the inner surface of the motor box 11. During operation, the motor box 11 can protect and support the servo motor 203.
[0021] Furthermore, the top of the connecting cylinder 601 is threadedly connected to a threaded connector 12, and the top of the threaded connector 12 is connected through a gas supply pipe 13. During operation, the high-pressure air cylinder can be delivered to the cleaning component 6 through the air supply pipe 13, and then sprayed out through the pressurized nozzle 603 for cleaning.
[0022] Working principle: When using this cleaning device to clean the furnace, high-pressure airflow is delivered to the connecting cylinder 601 through the gas supply pipe 13. After being guided by the guide plate 604, the high-pressure airflow is sprayed out from the pressurized nozzle 603 to clean the furnace. The impact of the high-pressure airflow on the guide plate 604 causes the inclined surface of the guide plate 604 to generate a component force that pushes the conical cylinder 602 to rotate, thereby causing the pressurized nozzle 603 to rotate during the air jet process. Subsequently, the servo motor 203 is connected to the power supply and energized, causing the transmission rod 202 to drive the threaded rod 201 to rotate. The threaded rod pushes the threaded cylinder 204 to slowly descend, thereby causing the cleaning component 6 to move slowly during the high-pressure gas cleaning process, moving the pressurized nozzle 603 to different positions for cleaning.
[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
