Description

Technical Field

[0001] This utility model belongs to the technical field of environmental protection equipment in the metallurgical industry, and relates to cold solidification pellets for dust removal, especially a forming equipment for cold solidification pellets. Background Technology

[0002] Cold-forming pellets are made from sludge, dust, and iron oxide scale produced in steelmaking, with the addition of lime and binders, and are produced into pellets using high-pressure pelletizing equipment. This process optimizes the raw material structure of steel plants. Traditional high-pressure pelletizing equipment, which processes raw materials into pellets through pressure rollers and then cleans the rollers, has the following problems:

[0003] 1. The finished pellets were not screened and were all transported away by conveyor belt, which resulted in some unqualified, small pellets and fragments being mixed in, resulting in inconsistent quality and affecting subsequent processes.

[0004] 2. The material remaining on the pressure roller will fall directly to the bottom of the equipment after being cleaned off. Over time, too much waste will accumulate inside the equipment, requiring regular cleaning and affecting the operation of the equipment.

[0005] To address these issues, we propose a cold-solidified pellet forming device. Utility Model Content

A feed inlet 11, which is funnel-shaped, is fixedly installed at the top of the housing 1. A ball-pressing assembly 2 is rotatably installed in the middle of the housing 1, located below the feed inlet 11, and is suitable for pressing the material entering the device into balls. Cleaning rods 4 are rotatably installed on both sides of the housing 1, and are driven to be installed on both sides of the ball-pressing assembly 2, suitable for cleaning the material adhering to the surface of the ball-pressing assembly 2. A discharge port 13 is provided at the bottom of the front end of the housing 1, suitable for discharging the finished balls. A recycling port 16 is provided at the bottom of the rear end of the housing 1, suitable for recycling and reprocessing unqualified balls and the waste material cleaned up.

[0034] like Figure 1 , Figure 3As shown, the ball-forming assembly 2 includes a pair of pressure rollers 25, each with a cylindrical structure. Several forming grooves 251 are spaced apart on the surface of each roller, each groove being hemispherical. The grooves 251 on the pair of rollers are arranged in a one-to-one correspondence, allowing them to interlock and form a sphere, thus pressing the material into balls. Both ends of the pair of rollers 25 extend to the outer end face of the equipment housing 1. Gears 21 are fixedly mounted on one end of each roller, and the two gears 21 are connected together, located on the front end face of the equipment housing 1. A base is fixedly mounted on the equipment housing 1, and a ball-forming motor 23 is fixedly mounted on the base.

The cross-section of the cleaning rods 4 is a cross-shaped structure, and a number of semi-circular protrusions 42 are spaced apart on the outer side of a pair of horizontal arms. The shape of the protrusions 42 corresponds to the shape of the forming groove 251, which facilitates scraping off the residual material in the forming groove 251 and on the surface of the pressure rollers 25. Both ends of the pair of cleaning rods 4 extend to the outer end face of the equipment housing 1. A circular cleaning rod drive block 41 is fixedly installed on one end of each pair of cleaning rods 4, and the pair of cleaning rod drive blocks 41 are located on the rear end face of the equipment housing 1.

The vibrating screen 3 is located below a pair of pressure rollers 25, and its bottom end is located at the discharge port 13. The pellets pressed by the pair of pressure rollers 25 fall downward onto the vibrating screen 3, which screens the pellets. Unqualified pellets and fragments fall to the bottom of the equipment casing 1, while qualified pellets slide down the vibrating screen 3 to the discharge port 13. An inclined guide plate 14 is fixedly installed at the discharge port 13. The cross-section of the guide plate 14 is shown in the figure. The structure is U-shaped, and the width of the guide plate 14 corresponds to the discharge port 13, which is suitable for the smooth sliding out of the pellets; the bottom surface of the inner side of the equipment shell 1 is set as an inclined ramp 15. The ramp 15 is an inclined V-shaped structure, and the lowest point of the bottom surface is located at the recovery port 16, so that the unqualified pellets screened by the vibrating screen 3 and the waste scraped off by the cleaning rod 4 can fall onto the ramp 15 and slide down along the ramp 15 to the recovery port 16 to complete the waste recycling and avoid accumulation inside the equipment shell 1.

[0037] like Figure 2 , Figure 4 As shown, a recycling component 5 is fixedly installed at the recycling port 16, suitable for crushing and recycling unqualified pellets and waste materials sliding out of the recycling port 16; the recycling component 5 includes a hydraulic cylinder 51, a crushing chamber 52, a recycling conveyor belt 53, a pressure plate 54, and a screening plate 55.

Below the hydraulic cylinder 51 is an output shaft 511, which extends into the interior of the crushing chamber 52. The bottom end of the output shaft 511 is fixedly installed... A fixed pressure plate 54 is installed to crush the waste material in the crushing chamber 52. A screening plate 55 is fixedly installed at the bottom end of the crushing chamber 52. The periphery of the screening plate 55 is fixed to the crushing chamber 52 by bolts, which facilitates installation, disassembly and replacement. The screening plate 55 includes several spaced round rods. The spacing between adjacent round rods is determined according to the usage requirements, so that the crushed waste material can be screened out. A recycling conveyor belt 53 is set below the screening plate 55. The recycling conveyor belt 53 is connected to the new material processing device, so that the crushed waste material is recycled and reprocessed and pressed together with the new material, thereby improving the finished product qualification rate and saving materials.
