Description

Technical Field

[0001] This utility model relates to the field of screening devices, and in particular to an automatic pellet screening device with selectable selection. Background Technology

[0002] Pelletizing is a product made by processing fine-grained materials (such as iron concentrate, coal powder, etc.) into spherical materials with a certain shape and strength through a specific process. Pelletizing is widely used in the iron and steel metallurgy industry. It has the advantages of uniform particle size, good air permeability, high iron content, and low harmful impurities.

[0003] In the existing technology, during the subsequent processing of pellets, in order to avoid the impact of inconsistent pellet size on the quality of the processed product, the pellets are usually screened. However, existing screening devices can usually only screen a single size. This means that for screening pellets with different specifications, different screens or different screening equipment need to be used multiple times, which is cumbersome, time-consuming, and labor-intensive, resulting in low screening efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic pellet screening device with selectable options, which is equipped with multiple screening cylinders, so as to simultaneously screen pellets of different diameters, thereby improving the screening efficiency of the screening device.

[0005] To achieve the above objectives, a selectable automatic pellet screening device is provided, comprising a base plate and a housing. Two first support rods are fixedly connected to the upper surface of the base plate. A common support frame is fixedly connected to the two first support rods. A hydraulic cylinder is fixedly connected to the support frame. A first connecting block is fixedly connected to the output end of the hydraulic cylinder. A first connecting shaft is fixedly connected to the inner surface of the first connecting block. A connecting rod is rotatably connected to the outer surface of the first connecting shaft. A second connecting shaft is rotatably connected to the inner surface of the connecting rod. A second connecting block is fixedly connected to the second connecting shaft. A motor is fixedly connected to the right surface of the housing. A rotating shaft is fixedly connected to the output end of the motor. A connecting frame is fixedly connected to the left end of the rotating shaft. A large-aperture screen cylinder is fixedly connected to the left surface of the connecting frame. A first connecting ring is fixedly connected to the outer surface of the housing. A medium-diameter screen cylinder is fixedly connected to the left surface of the first connecting ring. A second connecting ring is fixedly connected to the left surface of the medium-diameter screen cylinder. A small-diameter screen cylinder is fixedly connected to the left surface of the second connecting ring. A feed ring is fixedly connected to the left surface of the small-diameter screen cylinder. A first discharge chamber, a second discharge chamber, a third discharge chamber, and a fourth discharge chamber are fixedly connected to the outer surface of the housing. Two second support rods are fixedly connected to the upper surface of the bottom plate. Two connecting rods are fixedly connected to the outer surface of the housing. Rotating shafts are fixedly connected to the side surfaces of the two connecting rods. The outer surfaces of the two rotating shafts are rotatably connected to the two second support rods. Bearing rings are fixedly connected to the first discharge chamber, the second discharge chamber, and the third discharge chamber. Baffles are movably connected to the inner surfaces of the three bearing rings.

[0006] Multiple third connecting blocks are fixedly connected to the outer surface of the housing. A rotating rod is rotatably connected to the inner surface of each third connecting block. A movable block is fixedly connected to the rotating rod. The same protective plate is fixedly connected to two corresponding movable blocks. A handle is fixedly connected to the outer surface of the protective plate.

[0007] The bearing ring has a connecting groove, and the outer surface of the baffle is movably connected to the connecting groove.

[0008] The lower surface of the second connecting block is fixedly connected to the housing.

[0009] A guide ring is fixedly connected to the outer surface of the housing, and the inner surface of the feed ring is rotatably connected to the guide ring.

[0010] The outer surface of the rotating shaft is rotatably connected to the housing.

[0011] The first, second, third, and fourth discharge bins are all connected to the shell.

[0012] The above-mentioned solution has the following beneficial effects:

[0013] 1. By setting up large-aperture, medium-aperture, and small-aperture screen cylinders, this scheme sets up multiple screening cylinders, which can simultaneously screen pellets of different diameters, thereby improving the screening efficiency of the screening device.

[0014] 2. Through the design of the hydraulic cylinder, the first connecting block and the connecting rod, the tilt angle of the shell can be adjusted after the hydraulic cylinder is started. The greater the tilt angle of the shell, the faster the pellets fall inside the shell. During the use of the device, it can be adjusted according to actual needs, which improves the overall practicality of the device. Attached Figure Description

A small-aperture screen cylinder 18 is fixedly connected to the left surface of the second connecting ring 17. A feed ring 19 is fixedly connected to the left surface of the small-aperture screen cylinder 18. The outer surface of the housing 2 is respectively fixed... The casing 2 is fixedly connected to a first discharge bin 20, a second discharge bin 21, a third discharge bin 22, and a fourth discharge bin 23. Two second support rods 24 are fixedly connected to the upper surface of the base plate 1. Two connecting rods 25 are fixedly connected to the outer surface of the casing 2. Rotating shafts 26 are fixedly connected to the side surfaces of both connecting rods 25. The outer surfaces of the two rotating shafts 26 are rotatably connected to the two second support rods 24, respectively. Bearing rings 27 are fixedly connected to the first discharge bin 20, the second discharge bin 21, and the third discharge bin 22. Baffles 28 are movably connected to the inner surfaces of the three bearing rings 27. Multiple third connecting blocks 29 are fixedly connected to the outer surface of the casing 2. A rotating rod 30 is rotatably connected to the inner surface of the connecting block 29. A movable block 31 is fixedly connected to the rotating rod 30. The same protective plate 32 is fixedly connected to the two corresponding movable blocks 31. A handle 33 is fixedly connected to the outer surface of the protective plate 32. A connecting groove 34 is opened on the bearing ring 27. The outer surface of the baffle 28 is movably connected to the connecting groove 34. A guide ring 35 is fixedly connected to the outer surface of the housing 2. The inner surface of the feeding ring 19 is rotatably connected to the guide ring 35. The outer surface of the rotating shaft 12 is rotatably connected to the housing 2. The first discharge chamber 20, the second discharge chamber 21, the third discharge chamber 22 and the fourth discharge chamber 23 are all connected to the housing 2.

[0025] It should be noted that when the baffle 28 is inserted into the connecting groove 34, the baffle 28 can be pulled out of the connecting groove 34 according to actual needs. This allows selection of whether the pellets are being fed normally. By lifting the handle 33 upwards, the protective plate 32 and the structure on the protective plate 32 can be rotated around the rotating rod 30 in the third connecting block 29 as the central axis, thereby opening the protective plate 32. This facilitates observation of the screening of the pellets in the shell 2 and timely adjustment of the tilt angle. At the same time, under the action of the guide ring 35, the rotating shaft 12, connecting frame 13, large-diameter screen cylinder 14, first connecting ring 15, medium-diameter screen cylinder 16, second connecting ring 17, small-diameter screen cylinder 18 and feeding ring 19 can rotate, while also providing support for the feeding ring 19 and other structures.

[0026] Working principle: First, storage devices such as collection basins are installed below the first discharge bin 20, the second discharge bin 21, the third discharge bin 22, and the fourth discharge bin 23. Then, the baffle 28 is pulled out from the bearing ring 27. Then, the motor 11 is started. The motor 11 drives the rotating shaft 12, the connecting frame 13, the large-diameter screen cylinder 14, the first connecting ring 15, the medium-diameter screen cylinder 16, the second connecting ring 17, the small-diameter screen cylinder 18, and the feeding ring 19 to rotate. Then, the pellets are fed into the shell 2 through the feeding ring 19. The pellets inside shell 2 will first contact the small-aperture screen cylinder 18. Pellets that fit the aperture of the small-aperture screen cylinder 18 will fall through the apertures into the first discharge bin 20, and then through the first discharge bin 20 into the external receiving device. Simultaneously, pellets that do not fit the apertures will continue to enter the interior of shell 2 and contact the medium-aperture screen cylinder 16 and the large-aperture screen cylinder 14. At this point, pellets that fit the apertures of the medium-aperture screen cylinder 16 and the large-aperture screen cylinder 14 will pass through the apertures of the medium-aperture screen cylinder 16 and the large-aperture screen cylinder 14, and then through the second discharge bin 21 and the second discharge bin 22, respectively. 21. The pellets are lowered into the external receiving device, thus achieving simultaneous screening of pellets of various diameters. Finally, pellets that do not conform to the large-aperture screen cylinder 14, medium-aperture screen cylinder 16, and small-aperture screen cylinder 18 will fall into the external receiving device through the fourth discharge bin 23. The rotating shaft 12, connecting frame 13, large-aperture screen cylinder 14, first connecting ring 15, medium-aperture screen cylinder 16, second connecting ring 17, and small-aperture screen cylinder 18 are all in a rotating state, which can prevent the pellets from piling up and allow the pellets to be screened smoothly. The hydraulic cylinder 5 on the support frame 4 is activated to start the... The hydraulic cylinder 5 can drive the first connecting block 6 and the first connecting shaft 7 to move downwards. At this time, the moving first connecting shaft 7 will push the connecting rod 8 to move, thereby causing the moving connecting rod 8 to drive the second connecting shaft 9 and the second connecting block 10 to move downwards. At this time, the second connecting block 10 will drive the housing 2 and the structure on the housing 2 to rotate around the rotating shaft 26 as the central axis, thereby adjusting the angle of the housing 2. The greater the tilt angle of the housing 2, the faster the pellets fall inside the housing 2. During the use of the device, it can be adjusted according to actual needs.
