Description

Technical Field

[0001] This utility model relates to the field of material feeding technology for roller mills, specifically to an anti-clogging feed hopper for roller mills. Background Technology

[0002] In industrial production, various powders need to be mixed with water, stirred, and compacted using a roller mill to ultimately prepare grinding mud suitable for blast furnaces. Among these materials, clay, due to its inherent characteristics, exhibits significant airborne phenomena when transported by belt conveyors. Clay is lightweight and has fine particles; during belt conveyor transport, most of it is carried by the wind into the conveyor corridor, leading to resource waste and environmental pollution. Furthermore, the ton-bag loading method for clay requires consideration of reducing labor intensity during unloading. Currently, after clay is transported to the mine trough in ton-bag form, manual unloading is mostly used, which is labor-intensive and inefficient. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-clogging feed hopper for a roller mill, which enables clay in ton bags to be hoisted from the plant to the clay hopper on the steel platform of the roller mill by an overhead crane, and allows the clay to flow smoothly into the roller mill. This effectively solves the problem of resource waste caused by clay flying during belt conveying, eliminates the need for manual unloading, significantly reduces labor intensity, and improves work efficiency.

[0004] To achieve the above-mentioned technical effects, the present invention provides an anti-clogging feed hopper for a roller mill, comprising a hopper assembly, which includes a top pipe, a hopper tube, a bottom pipe, and an inclined pipe. The top and bottom surfaces of the hopper tube are both rectangular. The inner diameter of the top surface of the hopper tube is larger than the inner diameter of the bottom surface. The hopper tube is composed of four trapezoidal sidewalls welded together. The inner diameter of the top pipe is the same as the inner diameter of the top surface of the hopper tube and is fixedly connected to the top surface of the hopper tube. The inner diameter of the bottom pipe is the same as the inner diameter of the bottom surface of the hopper tube and is fixedly connected to the bottom surface of the hopper tube. The upper end of the inclined pipe is fixedly connected to the end of the bottom pipe away from the hopper tube, and the lower end of the inclined pipe is fixedly connected to the feed inlet of the roller mill. A scraper is fixedly connected to the inner sidewall of the hopper tube. The scraper is arc-shaped, and the height of the scraper near the axis of the hopper tube is greater than the height of the scraper near the inside of the hopper tube. The upward-facing arc-shaped surface of the scraper is the blade.

[0005] Furthermore, the scraper is provided with four scrapers, which are respectively fixedly connected to the inner side of the four trapezoidal sidewalls of the funnel tube. The four scrapers are evenly distributed around the axis of the funnel tube, and the ends of the four scrapers away from the sidewalls of the funnel tube are fixedly connected to each other.

[0006] Furthermore, a filter plate is fixedly connected to the top of the bottom tube. The filter plate has a rectangular cross-sectional shape and is fixedly connected inside the bottom tube. Multiple filter holes are evenly distributed on the filter plate.

[0007] Furthermore, a cover plate assembly is connected to the top surface of the jacking pipe. The cover plate assembly includes a cover plate and a handle. The handle is "n" shaped and is fixedly connected to the top surface of the cover plate assembly. The bottom surface of the cover plate is connected to the top surface of the jacking pipe, and the cover plate covers the jacking pipe.

[0008] Furthermore, multiple handles are evenly distributed in a matrix on the top surface of the cover plate.

[0009] Furthermore, it includes a support assembly, which includes top ribs, columns, and bottom ribs. There are four top ribs, which form a rectangular frame. The four top ribs are located on the outside of the jacking pipe. There are four columns, which are all located on the bottom surface of the top ribs. The four columns are located at the four corners of the rectangular frame formed by the four top ribs. There are four bottom ribs, which are all located below the top ribs. The two ends of the bottom ribs are fixedly connected to the side walls of the two columns. The four bottom ribs are located on the four sides of the rectangle.

[0010] Furthermore, the top and bottom reinforcing bars are both channel steel, and the columns are square steel.

[0011] Furthermore, the included angle between the two side walls of the blade is 15°.

[0012] The beneficial effects of this utility model are as follows: The design facilitates the addition of clay in ton bags, effectively solving the problem of resource waste caused by clay flying during belt conveying. The scraper can cut open the bottom of the ton bag, allowing the clay to flow smoothly into the roller mill, reducing labor intensity and improving work efficiency. The filter plate effectively prevents material impurities from entering the roller mill, protecting downstream equipment. The plate assembly allows for easy covering when not in use, improving equipment safety. The support assembly enhances the structural strength of the device and facilitates installation and use.
