Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ore processing, in particular to an iron ore screening equipment. BACKGROUND

[0002] In the process of ore processing, the ore needs to be crushed first, and the ore is crushed into a compound size requirement. However, the size of the ore cannot be accurately controlled during the crushing process, so the crushed ore needs to be screened to recover and crush the larger particle size ore again.

[0003] For example, patent application No. CN201810240222.9 discloses an ore screener. The smaller ore falls through the gap between the first and second screen rods, and the larger ore is stuck between the first and second screen rods. The first screen rod rotates in one direction, and the ore is flipped on the first screen rod and moves in one direction until it falls off the end of the screener, achieving the screening of different sizes of ore. The gap between the first and second screen rods is divided into small cells by the spacer, which prevents long ore from falling. The first screen rod is provided with raised stripes, toothed belts and other forms to make the entire ore screener structure more robust and reliable.

[0004] The screening method in the prior art causes small particles of ore to be washed out of the screener when the amount of ore falling is large, resulting in poor filtering effect. In addition, the screening equipment is prone to have ore stuck between the first and second screen rods. UTILITY MODEL CONTENT

[0005] The technical problem to be solved by the utility model is to provide an iron ore screening equipment to solve the problem of the prior art described in the background that the ore screening equipment is prone to cause the ore to be stuck and has poor screening effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an iron ore screening equipment, comprising

[0007] The screening bucket has a discharge hopper and two discharge pipes at the bottom, and the two discharge pipes are located on both sides of the discharge hopper.

[0008] The rotating column is rotatably arranged in the screening bucket.

[0009] The two baffles are fixedly connected to the rotating column.

[0010] The two screens are fixedly connected to the two ends of the rotating column and are fixedly connected to the baffles.

[0011] The two screen meshes are arranged at one end of the two baffles and at the other end of the discharge hopper and the two discharge pipes.

[0012] Preferably, the screen is a circular arc shape.

[0013] Preferably, the screening barrel is fixedly connected with a cross beam plate, a push cylinder is rotatably arranged on the cross beam plate, an output end of the push cylinder is rotatably connected with a push plate, and the push plate is fixedly connected to one end of the two baffle plates.

[0014] Preferably, the screen is an iron chain screen.

[0015] The beneficial effects of the above technical solutions are:

[0016] The push cylinder can drive the push plate to move, the push plate drives the baffle plate to rotate, the baffle plate drives the rotating column to rotate, the ore is guided into the two screens through the external conveying belt, and then the rotating column reciprocatingly rotates, so that the ore in the screen is screened.

[0018] Figure 2 is a sectional view of the iron ore screening device.

[0019] Figure 3 is a sectional view of the ore discharged from the screen.

[0020] Among them: the screening barrel 10, the discharge hopper 20, the discharge pipe 30, the rotating column 40, the push plate 41, the push cylinder 42, the cross beam plate 43, the baffle plate 50, the screen 60, the partition plate 61, the screen 70. DETAILED DESCRIPTION

[0021] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0022] As Figures 1-3 In this embodiment, an iron ore screening device includes

[0023] The screening barrel 10 has a discharge hopper 20 and two discharge pipes 30 at the bottom, and the two discharge pipes 30 are located on both sides of the discharge hopper 20.

[0024] The rotating column 40 is rotatably arranged in the screening barrel 10.

[0025] The two baffle plates 50 are fixedly connected to the rotating column 40.

[0026] The two screens 60 are fixedly connected to both ends of the rotating column 40 and fixedly connected with the baffle plates 50.

[0027] Two blocking nets 70 are respectively arranged at the two ends of the two baffle plates 50 and at the positions where the discharge hopper 20 intersects with the two discharge pipes 30.

[0028] This embodiment is implemented as follows:

[0029] In use, the rotating column 40 is reciprocatingly rotated by a small angle, which drives the two baffle plates 50 and the screen 60 to rotate, so that the ore on the screen 60 is shaken, which makes the ore be screened, and the ore meeting the requirements is discharged from the discharge hopper 20, and the ore with a larger particle size is left on the screen 60. When the ore on the screen 60 is more, the rotating column 40 is rotated by a larger angle, and the ore is poured from the two screens 60 into the two discharge pipes 30 respectively, so as to guide the ore out.

[0030] Meanwhile, the blocking net 70 can block the ore, so as to avoid the ore from flowing into the discharge pipe 30 and rushing into the discharge hopper 20.

[0031] Compared with the prior art, the application has the advantages that the ore can be conveniently screened, the screening effect is good, and the ore is not easy to be stuck.

[0032] Please refer to Figure 2 , 3 , the screen 60 is in a circular arc shape.

[0033] The circular arc-shaped screen 60 is more convenient for ore screening, and the ore is not easy to rush out of the screen 60 during screening.

[0034] Please refer to Figure 1 , 2 , 3, the screening bucket 10 is fixedly connected with a cross beam plate 43, the cross beam plate 43 is rotatably provided with a push cylinder 42, the output end of the push cylinder 42 is rotatably connected with a push plate 41, and the push plate 41 is fixedly connected to one end of the two baffle plates 50.

[0035] The push cylinder 42 arranged on the cross beam plate 43 can drive the push plate 41 to move, so that the push plate 41 pushes the baffle plate 50, and the baffle plate 50 drives the rotating column 40 to rotate.

[0036] Please refer to Figure 2 , 3 , the blocking net 70 is an iron chain net.

[0037] The iron chain net as the blocking net 70 is more durable.

[0038] The above is only a preferred embodiment of the application, and it should be pointed out that, for ordinary skilled persons in the art, without departing from the creative concept of the application, a number of modifications and improvements can be made, which all belong to the protection scope of the application.
