[0013] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of this utility model, and are not intended to limit the protection scope of this utility model.

[0014] Example: Please refer to Figure 1-2This utility model provides the following technical solution: a cleaning device for an electrofused refractory brick storage silo, comprising a silo cover 2 that can be snapped onto the top of the storage silo 1, a sleeve 3 that extends into the interior of the storage silo 1 and is fixedly connected to the center of the silo cover 2; a screw 4 is inserted into the sleeve 3; a sliding sleeve 5 located in the gap between the screw 4 and the sleeve 3 is threadedly connected to the screw 4; a plurality of circumferentially distributed support arms 51 are fixedly connected to the side wall of the sliding sleeve 5; the support arms 51 extend out of the sleeve 3 from a pre-set groove 31 on the side wall of the sleeve 3; the ends of the support arms 51 are fixedly connected to the inner side of an annular scraper 52. On the side, the outer side of the annular scraper 52 is provided with a U-shaped groove 53, and a rubber ring 6 is embedded in the U-shaped groove 53; the upper end of the screw 4 extends out of the hopper cover 2 and is fixedly connected to the driven gear 41, the driven gear 41 is meshed with the driving gear 71 connected to the end of the output shaft of the drive motor 7, and the drive motor 7 is fixedly connected to the upper surface of the hopper cover 2; the lower end of the screw 4 extends out of the sleeve 3 and is connected to a conical profile frame 42, the outer side of the profile frame 42 is connected to a brush 43, and the end of the brush 43 abuts against the inner wall of the conical part at the lower end of the storage hopper 1.

[0015] In use, first assemble all components, then hoist the cover 2 onto the upper end of the storage bin 1 and lower it down, then fix the cover 2 to the storage bin 1. Next, start the drive motor 7, transmitting power sequentially to the driving gear 71, driven gear 41, screw 4, and sliding sleeve 5. Because the sleeve 3 is fixed and the support arm 51 is restricted by the sliding groove 31, the sliding sleeve 5 cannot rotate when the screw 4 rotates, but moves upwards through the threaded connection. Then, the sliding sleeve 5 drives the support arm 51, which in turn drives the annular scraper 52. The rubber ring 6 connected to the annular scraper 52 vertically scrapes away dirt from the inner wall of the storage bin 1. According to the preset program of the drive motor 7's controller, when the annular scraper 52 reaches the uppermost stop position, the drive motor 7 reverses, driving the annular scraper 52 downwards. When it reaches the lower stop position, the drive motor 7 reverses again; this process repeats, driving the annular scraper 52 up and down, allowing for multiple scrapings of the inner wall of the storage bin 1, resulting in better cleaning. Meanwhile, the screw 4 drives the conical frame, which in turn drives the brush 43 to scrape the inner wall of the conical section at the lower end of the storage silo 1, cleaning the adhering dirt. This ensures that all dirt on the inner wall of the entire storage silo 1 can be cleaned. Based on this, personnel do not need to enter the storage silo 1, saving manpower. The drive motor 7 is located outside the storage silo 1, facilitating maintenance and control. The upper cylindrical section of the storage silo 1 is scraped by the rubber ring 6, and the conical section is repeatedly scraped by the brush 43, allowing for convenient and efficient cleaning of the inner wall of the storage silo 1. The rubber ring 6 is elastic, has high friction, provides good scraping effect, can be replaced after wear, has low operating costs, and will not damage the storage silo 1. Even if the brush 43 fails to completely clean the inner wall of the conical section, the conical section is close to the bottom outlet of the storage silo 1 and is low in position, making operation convenient. Personnel can use a water gun inserted into the storage silo 1 from the bottom outlet to clean the inner wall of the conical section, without needing to enter the storage silo 1.

[0016] To further improve the cleaning effect, water is sprayed to clean the inner wall of the storage silo 1 while scraping it; the silo cover 2 is connected to a water inlet pipe 21; the lower end of the water inlet pipe 21 extends into the lower part of the silo cover 2 and communicates with an annular water pipe 22 fixed to the lower part of the silo cover 2; the lower part of the annular water pipe 22 is provided with a plurality of circumferentially distributed downward inclined nozzles 23, and the spraying direction of the nozzles 23 is towards the inner wall of the storage silo 1.

[0017] An exemplary connection method between the sleeve 3 and the hopper cover 2 is as follows: the sleeve 3 extends into the storage hopper 1 through a pre-set through hole in the center of the hopper cover 2, and a connecting flange 32 is fixedly connected to its top; the connecting flange 32 covers the through hole and is fixed to the hopper cover 2 by screws. The assembly of the sliding sleeve 5, screw 4, support arm 51, and sleeve 3 can be performed before cleaning. Exemplarily, the connecting flange 32 is welded to the sleeve 3 last. First, the sliding sleeve 5 and screw 4 are installed into the sleeve 3, then the support arm 51 is inserted from the sliding groove 31 until it abuts against the sliding sleeve 5, and then the sliding sleeve 5 and support arm 51 are welded and fixed; then, the sleeve 3 containing the sliding sleeve 5 and screw 4 is inserted through the through hole, and finally the connecting flange 32 is welded to the sleeve 3.

[0018] To limit the downward movement of the screw 4, a thrust bearing 33 is connected to the screw 4 located between the connecting flange 32 and the driven gear 41. The lower end of the thrust bearing 33 abuts against the upper surface of the connecting flange 32. Alternatively, a limiting rod can be welded to the screw 4 and mounted on the top of the sleeve 3. However, the thrust bearing 33 allows for more flexible rotation of the screw 4, reduces wear, and extends its service life.

[0019] To control the stable rotation of the screw 4, a retainer 8 is connected to the lower end of the screw 4. The retainer 8 includes an outer ring 81 and an inner sleeve 82, which are fixed together by multiple circumferentially distributed spokes 83. The outer ring 81 has multiple connecting holes through which bolts pass to connect the outer ring 81 to the lower flange of the storage bin 1. The inner sleeve 82 is fitted onto the outside of the screw 4. This design prevents the screw 4 from swinging and confines it to the center position of the storage bin 1. The retainer 8 has multiple radial spokes 83 and is hollow, preventing water and dirt from falling in.

[0020] The advantage of this embodiment is that personnel do not need to enter the storage silo 1, saving time and effort; the combination of scraping and sweeping can conveniently and efficiently remove dirt from the inner wall of the storage silo 1; the drive motor 7 is outside the storage silo 1 and can be disassembled separately while retaining the screw 4 and the sleeve 3, which facilitates maintenance and control.

[0021] The parts of this utility model not described in detail are prior art; for those skilled in the art, the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. The scope of this utility model is defined by the appended claims and their equivalents.
