Description

TECHNICAL FIELD

[0001] The utility model relates to a sorting and crushing device, in particular to a device capable of screening and crushing large sintering raw materials on a belt, and belongs to the technical field of material sorting and crushing equipment. BACKGROUND

[0002] In the sintering process, the quality of raw materials plays a key role in the quality of sintered ore. After batching, the iron-containing materials are mixed into a mixture according to a certain ratio, and then fuel and solvent are added for mixing and granulation. The mixed material obtained after mixing and granulation controls the particle size composition. The mixed material is laid on the trolley and sintered by ignition and air extraction. At this time, the sintering process needs good and uniform air permeability, and the particle size composition of the mixed material plays a key role in air permeability. Good air permeability can improve the yield of sintered ore, while large pieces of material can damage the air permeability and uniformity of the mixed material. At the same time, the mixed material with uniform particle size has obvious effect on mineralization in the sintering process. Good mineralization can make the chemical composition of sintered ore uniform and qualified, and the strength index is good, which can improve the quality of sintered ore. Large pieces of material are not conducive to mineralization, and large pieces of material affect the chemical reaction and strength index in the sintering process. At present, large pieces of sintering raw materials on the belt are screened out by manual screening and then crushed and re-fed onto the belt. This process not only has high labor intensity, but also has low efficiency of sorting and crushing large pieces of raw materials, which cannot meet the needs of production. Therefore, a sorting and crushing device is needed to sort and crush large pieces of raw materials on the belt, thereby reducing the labor intensity of workers and improving the efficiency of sorting and crushing large pieces of raw materials. SUMMARY

[0003] The utility model aims at overcoming the defects of prior art, and provides a sintering large piece of raw material sorting and crushing device, which can not only reduce the labor intensity of workers, but also improve the sorting and crushing efficiency of large pieces of raw materials.

The bottom support part is arranged on the ground across the large belt. The screen mesh is arranged on the bottom support part and located directly below the discharge end of the small belt. The material cleaning part is arranged on the bottom support part. The crusher is suspended above the large belt by a support, and the crusher and the material cleaning part are respectively located on both sides of the bottom support part along the center line direction of the large belt.

[0006] The above-mentioned sintering bulk raw material sorting and crushing device includes a base support comprising a square frame, guide rods, and weighing devices. The four corners of the square frame are mounted on the ground via brackets, with the square frame positioned directly above the large conveyor belt and directly below the end of the small conveyor belt. Holes are provided at the four corners of the upper surface of the square frame, and a weighing device is installed at the bottom of each hole. Guide rods are inserted into each hole, and the bottom ends of the guide rods are mounted on the weighing devices corresponding to their positions. The four corners of the lower surface of the screen are connected to the top ends of the four guide rods.

[0007] The above-mentioned sintered bulk raw material sorting and crushing device includes a cleaning section comprising an electric cylinder, a pusher plate, and a V-shaped baffle. The electric cylinder is mounted on the side wall of a square frame via a bracket, and the axis of the electric cylinder piston rod is parallel to the center line of the large belt. The end of the electric cylinder piston rod is connected to the pusher plate. The bottom surface of the pusher plate contacts the top surface of the screen, and the length of the pusher plate is the same as the length of the screen, with the length direction line of the pusher plate parallel to the length direction line of the screen. The maximum extension length of the electric cylinder piston rod is greater than the width of the screen. The V-shaped baffle is located at the top of the electric cylinder housing, with its tip pointing upwards.

[0008] In the above-mentioned sintered bulk raw material sorting and crushing device, the crusher is located directly below the end of the square frame away from the electric cylinder.

[0009] This invention effectively sorts large pieces of raw material through a screen, preventing them from falling directly from the small conveyor belt to the large conveyor belt. Then, the bottom support determines the amount of large material accumulated on the screen, and the cleaning section pushes the large pieces of raw material on the screen to the crusher for crushing. The crushed material then falls back onto the large conveyor belt. Attached Figure Description
