Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of cleaning sintering mud roller feeders, and more specifically, to a device for preventing material sticking to sintering mud roller feeders. Background Technology

[0002] In the sintering production process of iron and steel metallurgy, the sintering mud roller distributor is a core piece of equipment connecting the raw material silo and the sintering machine. It uses the rotation of the mud rollers to evenly transport the mixed sintering raw materials (such as iron ore powder, fuel, and flux) onto the sintering machine trolley. The uniformity of the material layer thickness directly determines the sintering quality and yield. However, in sintering production, to adapt to the needs of different blast furnaces, it is necessary to frequently adjust the raw material composition (such as changing the iron ore powder ratio and adjusting the moisture content). This process easily leads to serious material sticking problems in the sintering mud roller distributor, which in turn triggers a series of chain reactions, severely affecting the stability of sintering production and product quality.

[0003] When the proportion of fine-particle raw materials in the sintering batch increases or the moisture content exceeds 8%-10%, the raw materials tend to adhere to the surface of the mud roller due to increased viscosity. As production continues, the adhering material accumulates and compacts on the mud roller, gradually forming a hard agglomerated layer. The hardened adhering material layer will continuously rub against the inner wall of the feed hopper as the mud roller rotates, leading to accelerated wear of the feed hopper. The original standard feed hopper width of 100-150mm may expand to 180-220mm within 1-2 months, and the inner wall becomes rough and irregular.

[0004] Therefore, developing a device that can solve the problem of material sticking in the sintering mud roller feeder has become an urgent need to ensure stable sintering production and reduce costs. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a device for preventing material sticking to a sintering mud roller feeder, which solves the technical problem in the prior art where material continuously accumulates and compacts on the mud roller, gradually forming a hard agglomerated layer, affecting production.

[0023] like Figures 1-4 As shown, it illustrates a device for preventing material sticking in a sintering mud roller distributor according to an embodiment of the present disclosure, comprising: A connecting bracket 1 and a cylindrical cylinder 2 are provided, with the cylindrical cylinder 2 being horizontally mounted on the connecting bracket 1. A plurality of scrapers 3 and a driving cleaning assembly 4, wherein the scrapers 3 are all disposed on the cylinder 2 and the driving cleaning assembly 4 is disposed between the cylinder 2 and the connecting bracket 1; A loading and unloading connection assembly 5 is disposed between the scraper 3 and the cylinder 2; The drive cleaning assembly 4 includes a transmission seat 4-1, which is vertically fixed to the side surface of the connecting bracket 1. One end of the cylinder 2 is horizontally rotatably fitted inside the transmission seat 4-1. A driven gear 4-2 is provided on the outer surface of the cylinder 2. A drive gear 4-3, which is driven by electricity, is provided on one side of the connecting bracket 1. The drive gear 4-3 meshes with the driven gear 4-2. A circular opening 4-4 ​​is provided on the side surface of the connecting bracket 1, which is connected to the cylinder 2. A fixing frame 4-5 is provided on one side of the connecting bracket 1. A pull-out auger 4-6 is rotatably connected between the fixing frame 4-5 and the inner side of the cylinder 2. The pull-out auger 4-6 is driven by electricity. Several elongated openings 4-7 are provided on the surface of the cylinder 2.

[0024] In some examples, in order to achieve stable rotation of the cylinder 2 and scraper 3 to clean the sintered slurry, and at the same time quickly collect and discharge the waste generated during cleaning, so as to avoid the accumulation of waste and secondary material sticking, and ensure the continuous and stable operation of the distributor, a drive cleaning component 4 is designed. This component includes a transmission seat 4-1 that is vertically fixed to the side surface of the connecting bracket 1, which provides horizontal rotation support for the cylinder 2. One end of the cylinder 2 is fitted into the transmission seat 4-1 and can rotate smoothly around its own axis, ensuring that the scraper 3 can evenly adhere to the surface of the distributor for cleaning when the cylinder 2 rotates, and avoiding uneven cleaning or wear of the scraper 3 due to the shaking of the cylinder 2.

[0025] The driven gear 4-2 on the outer surface of the cylinder 2 meshes with the electrically driven drive gear 4-3 on one side of the connecting bracket 1, forming a stable gear transmission mechanism. The electric drive can precisely control the speed of the drive gear 4-3, thereby driving the driven gear 4-2 to rotate synchronously with the cylinder 2, ensuring that the scraping speed of the scraper 3 matches the operating rhythm of the material distributor, thus avoiding excessive wear of the scraper 3 due to excessive speed, and preventing mud residue from sticking due to excessively slow speed.

[0026] The circular opening 4-4 ​​on the side surface of the connecting bracket 1 is connected to the cylinder 2, providing a channel for the scraped waste to enter the inside of the cylinder 2. The mud and waste scraped off by the scraper 3 can fall into the cylinder 2 through the circular opening 4-4, preventing the waste from scattering to the outside of the equipment and causing pollution or accumulation.

[0027] The screw conveyor 4-6, which is rotatably connected between the fixed frame 4-5 on one side of the connecting bracket 1 and the inner side of the cylinder 2, is driven by electricity to rotate. Its spiral structure can continuously transport the waste in the cylinder 2 to the outside of the cylinder 2 along the axial direction, so as to realize the rapid discharge of waste. The screw conveyor method can effectively avoid the blockage of waste in the cylinder 2 and ensure that the waste discharge channel is unobstructed.

[0028] Several long openings 4-7 on the surface of cylinder 2 can help collect the waste material scattered during the scraping of scraper 3, further improving the waste material collection efficiency.

[0029] During operation, the drive gear 4-3 rotates the cylinder 2, and the scraper 3 scrapes the mud. Waste enters the cylinder 2 through the circular opening 4-4 ​​and the long opening 4-7, and is then conveyed out by the auger 4-6. Stable transmission ensures uniform scraping, and the auger conveying achieves efficient waste discharge. All components work together to complete dynamic scraping and waste treatment, effectively preventing sintered mud from sticking.

[0030] like Figures 1-4As shown in the figure, the loading and unloading connection assembly 5 in this embodiment includes a plurality of bosses 5-1, which are evenly distributed around the surface of the cylinder 2. A sliding slot 5-2 is provided in the boss 5-1, and the scraper 3 is horizontally slidably inserted into the sliding slot 5-2. A spacer 5-3 is horizontally slidably inserted into the sliding slot 5-2 and connected to it. The spacer 5-3 is supported between a pair of adjacent scrapers 3. An external thread layer 5-4 is provided on a section of the surface of the cylinder 2. A clamping sleeve 5-5 is screwed onto the external thread layer 5-4 by threads. The clamping sleeve 5-5 is attached to the side end face of the scraper 3 at the tail end.

[0031] In some examples, in order to enable quick disassembly and replacement of scraper 3 and flexible adjustment of its distribution position to adapt to the cleaning needs of different specifications of material spreaders, and at the same time ensure that scraper 3 is stable and reliable after installation and avoids scraping failure due to displacement of scraper 3 during the cleaning process, a loading and unloading connection component 5 is designed. This component includes bosses 5-1 evenly distributed around the surface of cylinder 2 to provide a mounting base for scraper 3. The sliding slot 5-2 in the boss 5-1 is adapted to scraper 3, and scraper 3 can be horizontally slid into the slot to achieve quick positioning and installation without the need for complex connecting parts, which greatly simplifies the scraper 3 loading and unloading process and reduces the difficulty of maintenance operations.

[0032] The horizontally inserted spacer strip 5-3 in the sliding slot 5-2 is supported between adjacent scrapers 3. By replacing the spacer strip 5-3 with different thicknesses, the spacing between adjacent scrapers 3 can be adjusted, thereby changing the distribution density of scrapers 3 on the surface of cylinder 2. When the mud on the surface of the distributor is highly viscous, the thickness of the spacer strip 5-3 can be reduced to increase the density of scrapers 3 and increase the cleaning frequency. When the mud is less viscous, the thickness of the spacer strip 5-3 can be increased to reduce the number of scrapers 3 and reduce the energy consumption of the equipment.

[0033] The spacer bar 5-3 can also provide lateral restraint for the scraper 3, preventing the scraper 3 from shifting laterally along the slot during the cleaning process and ensuring that the scraper 3 is always evenly distributed.

[0034] The clamping sleeve 5-5, screwed onto the external thread layer 5-4 on the surface of the cylinder 2, fits against the side end face of the tail scraper 3. Tightening the clamping sleeve 5-5 can apply axial pressure to the scraper 3 and the spacer strip 5-3 in the slot, fixing them tightly in the slot and preventing the scraper 3 from loosening and falling off due to centrifugal force or cleaning resistance when the cylinder 2 rotates. When disassembling the scraper 3, simply loosen the clamping sleeve 5-5 to pull the scraper 3 and the spacer strip 5-3 out of the slot, which is convenient to operate.

[0035] During operation, adjust the spacing of scraper 3 according to the requirements by selecting the spacer bar 5-3, insert it into the slot, and tighten the clamping sleeve 5-5 to fix it. When scraper 3 is worn, loosen the clamping sleeve 5-5 to replace it. The slot installation simplifies installation and disassembly, the spacer bar 5-3 can be adjusted and distributed, and the clamping sleeve 5-5 ensures stability. All components work together to enable convenient maintenance and flexible adaptation of scraper 3, improving the practicality of the anti-sticking device.

[0036] For example, such as Figure 2 As shown, a shield 6 is provided on the side surface of the connecting bracket 1, and the shield 6 covers the driven gear 4-2 and the driving gear 4-3.

[0037] In some examples, a shield 6 is provided on the side surface of the connecting bracket 1, covering the driven gear 4-2 and the driving gear 4-3. This effectively prevents sintered clay waste, dust, and external debris from entering the gear meshing area, avoiding gear wear or transmission failure due to foreign object jamming, and ensuring the stability and service life of the gear transmission. The shield 6 adopts a closed design while reserving necessary heat dissipation gaps, which affects heat dissipation during gear operation.

[0038] For example, such as Figure 1 As shown, a discharge chute 7 is provided on one side of the connecting bracket 1, and one end of the discharge chute 7 is inclined downward.

[0039] In some examples, the discharge hopper 7, located on one side of the connecting bracket 1, is inclined downwards at one end. This provides a guiding channel for the waste material conveyed by the auger 4-6, allowing the waste to slide down the inclined hopper surface under gravity to a designated collection container, preventing the waste from scattering and causing pollution around the equipment during discharge. The inclination angle of the discharge hopper 7 is adaptively designed to ensure that the waste material slides smoothly without accumulation. Its inlet precisely connects with the discharge end of the auger 4-6, maximizing the reception of discharged waste and reducing material loss.

[0040] For example, such as Figure 4 As shown, the cross-section of the connection between the sliding slot 5-2 and the scraper 3 has an L-shaped structure.

[0041] In some examples, the cross-section of the connection between the sliding slot 5-2 and the scraper 3 is L-shaped. This structure creates a double limit in both the lateral and longitudinal directions after the scraper 3 is inserted into the slot. Compared with a planar connection, this structure can more effectively resist the radial and axial forces generated by the scraper 3 during cleaning, prevent the scraper 3 from tilting or falling off during the cleaning process, ensure the fit between the scraper 3 and the surface of the fabric spreader, and guarantee a stable cleaning effect.

[0042] In practical use: Select appropriate scraper 3 and spacer strip 5-3 according to the specifications of the sintering mud roller distributor. Horizontally insert scraper 3 into the boss 5-1 of cylinder 2 via the sliding slot 5-2 of the mounting and dismounting assembly 5. Adjust the spacing between adjacent scraper 3 by inserting spacer strips 5-3. Tighten the clamping sleeve 5-5 on the external thread layer 5-4 to securely fix the scraper 3 and spacer strip 5-3. Start the drive cleaning assembly 4. The electric drive rotates the drive gear 4-3, which meshes with the driven gear 4-2, causing cylinder 2 to rotate around the transmission seat 4-1. The scraper 3 rotates synchronously with cylinder 2, scraping away the material adhering to the surface of the distributor. The scraped waste enters cylinder 2 through the circular opening 4-4 ​​of the connecting bracket 1 and the long opening 4-7 on the surface of cylinder 2. Simultaneously, the auger 4-6 is activated, conveying the waste axially along cylinder 2 to the discharge hopper 7. The waste falls into the collection container along the inclined hopper. If scraper 3 needs to be replaced, simply loosen the clamping sleeve 5-5, pull out the old scraper 3 and spacer strip 5-3, replace the new parts, and then fix them back in place. This achieves dynamic anti-sticking and convenient maintenance throughout the process.
