[0016] 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.

[0017] See Figures 1-5A pre-oxidation furnace cleaning device includes an upper plate 1, a lower plate 2, a collection component 3, a bidirectional cleaning component 4, a drive wheel 9, a drive component 10, and adjusting springs 11. The upper plate 1 forms the top support structure of the device, the lower plate 2 is disposed at the bottom of the upper plate 1 and is arranged parallel to the upper plate 1, the collection component 3 is installed between one side of the upper plate 1 and the lower plate 2, the bidirectional cleaning component 4 is installed on the upper plate 1 and the lower plate 2, the drive wheel 9 is rotatably disposed on both sides of the upper plate 1 and the lower plate 2, the drive component 10 is installed on the upper plate 1 and the lower plate 2, and at least two adjusting springs 11 are fixedly disposed between the upper plate 1 and the lower plate 2.

[0018] Driven by motor 22, the device moves at a constant speed inside the furnace, eliminating the need for manual dragging and reducing labor intensity. It also ensures the uniformity of the cleaning operation. Adjusting spring 11 allows the device to automatically adapt to furnace spaces of different heights. The brush head 5 and cleaning roller 8 in the bidirectional cleaning component 4 work together to achieve all-round cleaning of the top and sides of the furnace. The cleaning roller 8 fits tightly against the arc-shaped inner wall of the furnace side through an adaptive structure, effectively solving the problem of missed cleaning. The collection component 3 can collect dust and impurities generated during the cleaning process in a timely manner, preventing dust from spreading in the air and improving the working environment.

[0019] First, refer to Figure 1 In this embodiment, the upper plate 1 is located at the top of the device, and the lower plate 2 is located below the upper plate 1. Together, they form the support frame of the device. Multiple adjusting springs 11 are provided between the upper plate 1 and the lower plate 2. These adjusting springs 11 are distributed vertically and their two ends are fixedly connected to the upper plate 1 and the lower plate 2, respectively. When the device is placed inside the furnace, the adjusting springs 11 can automatically adjust the distance between the upper plate 1 and the lower plate 2 according to the actual height of the furnace interior space, so that the device can adapt to different working environments. This automatic adjustment function ensures that the device can maintain a stable working state in pre-oxidation furnaces of different specifications, providing a reliable foundation for subsequent cleaning operations.

[0020] Multiple sets of drive wheels 9 are provided on both sides of the upper plate 1 and the lower plate 2. These drive wheels 9 are installed in the mounting grooves 14 of the upper plate 1 and the lower plate 2 via rotating shafts 15. Mounting covers 16 are fixedly installed at both ends of the rotating shafts 15. The mounting covers 16 are fixedly connected to the drive wheels 9. The drive wheels 9 are in contact with the inner surface of the furnace, bear the weight of the device and provide the movement function. The arrangement of the drive wheels 9 is carefully designed to ensure that the device remains stable when moving in the furnace and will not deviate or get stuck. Each drive wheel 9 can independently adapt to the slight unevenness at the bottom of the furnace, ensuring the smooth movement of the entire device.

[0021] Then, refer to Figure 4In this embodiment, the drive assembly 10 provides the power required for the device to move. The motor 22 is fixedly installed in the mounting holes 21 of the upper plate 1 and the lower plate 2. Belt grooves 17 are provided on the lower plate 2 and the upper plate 1. These belt grooves 17 are interconnected with the mounting grooves 14. The support base 18 is fixed on the upper plate 1 and the lower plate 2, and its number is consistent with the belt grooves 17. A support shaft 19 is rotatably installed on the support base 18. The output shaft of the motor 22 is connected to the support shaft 19 through the second transmission belt 23. The support shaft 19 is connected to the rotating shaft 15 through the first transmission belt 20. The first transmission belt 20 slides in the belt groove 17. When the motor 22 starts, the rotational power is transmitted to the rotating shaft 15 in sequence through the second transmission belt 23, the support shaft 19, and the first transmission belt 20, driving the drive wheel 9 to rotate and making the device move at a constant speed along the length of the furnace. This transmission method ensures the stability and reliability of power transmission, enabling the device to complete the cleaning operation of the entire furnace at a constant speed.

[0022] The cleaning function is achieved by the bidirectional cleaning component 4, which includes brush heads 5 fixedly installed on both sides of the upper plate 1 and the lower plate 2. The installation height of the brush heads 5 is higher than that of the drive wheels 9, ensuring that the brush heads 5 can preferentially contact the inner wall surface of the furnace during the movement of the device. The brush heads 5 adopt a rigid structure and remove the impurities attached to the surface through the scraping action with the inner wall of the furnace. This height difference design allows the brush heads 5 to loosen and remove larger particles of attached material first, creating conditions for subsequent fine cleaning. The arrangement of the brush heads 5 covers the main areas of the top and sides of the furnace, ensuring that there are no obvious cleaning dead corners.

[0023] Secondly, see Figure 2 In this embodiment, mounting rings 6 are fixedly installed on both sides of the upper plate 1 and the lower plate 2. A support plate 7 is connected between the left and right corresponding mounting rings 6. A cleaning roller 8 is rotatably installed on the side of the support plate 7. To enhance the adaptability of the cleaning roller 8 to the arc-shaped structure of the furnace side, a rotating plate 12 is installed on the support plate 7 by means of hinge. The cleaning roller 8 is installed at the end of the rotating plate 12. A first spring 13 is fixedly installed on both sides of the support plate 7. The other end of the first spring 13 is connected to the rotating plate 12 and arranged at an angle. When the cleaning roller 8 contacts the side of the furnace, the change in the furnace wall contour will cause the rotating plate 12 to rotate accordingly. The first spring 13 will then generate an elastic restoring force, pushing the cleaning roller 8 to always keep it in close contact with the arc-shaped inner wall surface of the furnace. This adaptive structure enables the cleaning roller 8 to effectively remove various impurities in the arc-shaped area of ​​the furnace side, including those hard-to-handle corners and attachments on curved surfaces. During the rotation, the cleaning roller 8 maintains appropriate contact pressure with the inner wall of the furnace, which ensures the cleaning effect and avoids damage to the inner wall of the furnace.

[0024] Again, see Figure 3In this embodiment, the dust collection system is responsible for handling the dust and debris generated during the cleaning process. The collection component 3 is installed on one side of the upper plate 1 and the lower plate 2, located at the rear of the device in the direction of travel. The collection component 3 includes a collection frame 24, which is fixed between the upper plate 1 and the lower plate 2. A spring hose 25 is connected to the side of the collection frame 24, and a dust collection bag 26 is connected to the other end of the spring hose 25. The spring hose 25 is in communication with the collection frame 24 and the dust collection bag 26. During the cleaning process, the dust stripped by the brush head 5 and the cleaning roller 8 enters the collection frame 24 under the action of the device's forward thrust, and is then guided into the dust collection bag 26 for storage through the spring hose 25. The collection frame 24 is made of flexible material, which can form an effective seal with the inner wall of the furnace to prevent dust from escaping from the gaps. This immediate collection method ensures the cleanliness of the working environment and avoids dust from harming the health of the operators.

[0025] Finally, see Figure 1 In this embodiment, a connecting plate 27 is fixedly arranged between the drive wheels 9. The connecting plate 27 is arranged in a rotatable manner by stacking them up and down. This structure enhances the linkage between the drive wheels 9 and improves the stability of the device movement. The arrangement of the connecting plate 27 enables each drive wheel 9 to work together, share the weight of the device, and maintain overall balance when encountering uneven surfaces.

[0026] When using this pre-oxidation furnace cleaning device, the device is first placed at the furnace inlet. The adjusting spring 11 automatically adjusts the height of the device to adapt to the internal dimensions of the furnace. This automatic adjustment process is fast and accurate, ensuring that the device maintains a suitable fit with the internal contour of the furnace. The motor 22 is started, and the drive assembly 10 drives the drive wheel 9 to rotate, so that the device enters the furnace at a uniform speed. The working speed of the motor 22 is precisely controlled to ensure that the device moves at the optimal speed, which not only ensures the cleaning effect but also improves the work efficiency.

[0027] The brush head 5 at the forefront first contacts the inner wall surface of the top and sides of the furnace, removing most of the larger particles of impurities attached to the surface through scraping. The rigid structure and reasonable arrangement of the brush head 5 enable it to effectively handle various types of deposits. As the device continues to move forward, the cleaning roller 8 begins to contact the side area of ​​the furnace. When it encounters the arc-shaped structure on the side of the furnace, the adaptive mechanism of the cleaning roller 8 begins to function. The rotating plate 12 automatically adjusts its angle under the action of the first spring 13, ensuring that the cleaning roller 8 always maintains good contact with the inner wall of the furnace. Through rotational friction, it further removes the remaining stubborn impurities. This layered cleaning method ensures that each area is thoroughly cleaned.

[0028] While the entire cleaning operation is underway, the dust collection system works simultaneously. The collection frame 24 is located at the rear of the device and continuously receives the removed impurities and dust. Because the collection frame 24 is made of flexible material, it can form a relatively sealed contact with the inner wall of the furnace, effectively preventing dust from escaping backward. The dust entering the collection frame 24 is transported to the dust collection bag 26 for storage through the spring hose 25 under the action of the airflow generated by the movement of the device. This design allows the dust to be captured almost at the same time as it is generated, greatly reducing the dust content in the air.

[0029] The device moves continuously along the length of the furnace until the cleaning of the entire furnace is completed. Throughout the process, the various systems coordinate and cooperate to complete the cleaning task. The drive component 10 keeps the device moving at a constant speed to ensure that the cleaning time of each section is consistent. The adjustment system adjusts the working status of the device at any time to adapt to the structural changes inside the furnace. The cleaning system performs the work in layers. First, the brush head 5 performs preliminary cleaning, and then the cleaning roller 8 performs fine cleaning. The collection system processes the work products in a timely manner to keep the environment clean. The entire operation is carried out continuously without human intervention, realizing the mechanization and automation of the cleaning operation.
