[0001] This application belongs to the field of steel smelting tool technology, specifically relating to a perforation device for the material surface of a sintering machine with adjustable forward and reverse thread screws. Background Technology
[0002] Sintering is a crucial step in the entire steel production process. As the upstream process of blast furnace ironmaking, the quality of sintered ore plays a decisive role in blast furnace ironmaking output, energy consumption, pig iron quality, and blast furnace lifespan. Currently, the industry generally promotes thick-layer sintering. However, when the sintering layer reaches a certain thickness, it leads to problems such as decreased permeability, reduced sintering speed, and over-melting of the lower layer of sinter, resulting in deteriorated physical and chemical properties. Therefore, improving the permeability of the sintering layer has become key to increasing the layer thickness and ensuring the quality of sintered ore.
[0003] In recent years, many sintering machine material surface perforation technologies have emerged, which make the sintering reaction more complete and the combustion more uniform and thorough. However, they are complex in structure and inconvenient to operate. Therefore, this invention proposes a sintering machine material surface perforation device with a simple structure and flexible and convenient operation using a forward and reverse thread screw adjustment.

[0028] See also Figure 1-2As shown, according to an embodiment of this application, a sintering machine material surface drilling device with adjustable positive and negative thread screws is provided, including: a support 1, a connecting component 2, a roller cone 3, and a drive component 4; a space for trolley movement is provided between the supports 1, the connecting component 2 is slidably disposed between the supports 1, the roller cone 3 is rotatably connected to the connecting component 2, and the drive component 4 is disposed on the supports 1, the drive component 4 being able to drive the connecting component 2 to slide up and down along the supports 1, so that the roller cone 3 can drill holes in the material layer of the trolley.
[0029] Specifically, two support brackets are vertically installed on both sides of the trolley, allowing the trolley to move between the support brackets. The drive assembly 4 is installed on the support brackets and drives the connecting assembly 2 installed between the support brackets to slide up and down, adjusting the position of the roller cone 3 as needed so that the roller cone 3 contacts the material layer stored in the trolley. During the movement of the trolley, the roller cone 3 becomes a passive roller, and the rotation of the roller cone 3 achieves alternating drilling on the material surface. During the drilling process, the height of the connecting assembly 2 does not change due to force, and the drilling depth is stable, thereby improving the air permeability of the sintering machine material layer, making the sintering reaction of the material layer more complete, and the combustion more uniform and thorough. This device has a simple structure, the drilling depth can be adjusted according to the usage requirements, and it is easy to operate and maintain.
[0030] The drive assembly 4 includes: a drive rod 41, a slider 42, and a connecting rod 43;
[0031] The drive rod 41 is rotatably mounted on the bracket 1, the slider 42 is symmetrically mounted on the drive rod 41, and the connecting rod 43 is mounted between the drive rod 41 and the connecting assembly 2. Rotating the drive rod 41 can drive the slider 42 to move towards or away from the drive rod 41.
[0032] The drive rod 41 has a reverse thread on its outer circumference, and the slider 42 is symmetrically arranged on the reverse thread on the drive rod 41.
[0033] Specifically, the drive rod 41 has reverse threads on both sides, and the slider 42 is symmetrically installed on the reverse threads. The slider 42 is threadedly connected to the drive rod 41. When the drive rod 41 is rotated, the slider 42 can move in opposite directions on the drive rod 41. Then, through the connecting rod 43, the connecting component 2 can slide up or down on the bracket 1 to adjust the position of the roller cone 3.
[0034] The slider 42 and the drive rod 41 are connected by a thread. When the roller cone 3 punches the material layer of the trolley and is subjected to an upward force, the external thread on the slider 42 and the drive rod 41 form a self-locking mechanism. The slider 42 will not move and can always maintain the position of the roller cone 3 to stabilize the punching depth.
[0035] The connecting rod 43 is connected to the slider 42 and the connecting component 2 in the vertical direction. The slider 42 can move in opposite directions on the driving rod 41 to drive the connecting component 2 to move up and down. At the same time, the connecting component 2 is slidably connected to the bracket 1, which can limit the slider 42 so that the slider 42 will not rotate with the driving rod 41 during the rotation of the driving component 4, and can move in opposite directions to adjust the position of the roller cone 3.
[0036] The connecting rod 43 is rotatably connected to the slider 42.
[0037] The drive assembly 4 also includes a handwheel 44, which is mounted on the drive rod 41 and is used to drive the drive rod 41 to rotate.
[0038] The drive assembly 4 also includes a seated bearing 45, which is disposed on the top of the bracket 1, and the drive rod 41 is connected to the bracket 1 through the seated bearing 45.
[0039] Specifically, the handwheel 44 is mounted on one end of the drive rod 41, which is connected to the bracket 1 via a seated bearing 45. The operator can rotate the drive rod 41 by using the handwheel 44, which facilitates applying force to the drive rod 41. The seated bearing 45 facilitates the rotation of the drive rod 41 while reducing the friction generated when the drive rod 41 rotates.
[0040] The connecting assembly 2 includes: a crossbeam 21, a side column 22, and a guide wheel 23;
[0041] The side columns 22 are disposed on both sides of the crossbeam 21, the connecting rod 43 is hinged to the crossbeam 21, the guide wheel 23 is disposed on the side columns 22, the guide wheel 23 is slidably connected to the bracket 1, and the roller cone 3 is rotatably disposed between the side columns 22.
[0042] The connecting component 2 also includes a lug 24, which is provided on the crossbeam 21, and the connecting rod 43 is hinged to the lug 24.
[0043] A slide rail is provided on the side wall of the bracket 1, and the guide wheel 23 is slidably disposed in the slide rail.
[0044] Specifically, the crossbeam 21 is horizontally arranged between the supports 1. Two lugs 24 are installed on the top of the crossbeam 21. One end of the connecting rod 43 is hinged to the lug at the bottom of the slider 42, and the other end is hinged to the lug 24 on the crossbeam 21. A slide is provided on the side wall of the support 1. The guide wheel 23 is slidably installed in the slide, which can limit the slider 42 so that when the drive rod 41 rotates, the slider 42 can move in opposite directions on the drive rod 41. It can also guide the crossbeam 21 so that the crossbeam 21 and the side column 22 can move up and down in the support 1, thereby realizing the adjustment of the height of the roller cone 3.
[0045] The roller cone 3 includes a roller body 31 and a punching rod 32. The roller body 31 is connected to the side column 22, and the punching rod 32 is disposed on the outer circumference of the roller body 31.
[0046] A seated spherical bearing 5 is provided between the roller body 31 and the side column 22.
[0047] Specifically, the punching rods 32 are distributed on the outer circumference of the roller body 31. After the punching rods 32 on the roller cone 3 are adjusted to the height that they can extend into the material layer, the roller body 31 can become a passive roller during the movement of the trolley. The rotation of the roller body 31 enables the punching rods 32 to punch holes alternately on the material surface. The punching depth is stable, which improves the air permeability of the sintering machine material layer, makes the sintering reaction of the material layer more complete, and the combustion more uniform and thorough.
