Description

Technical Field

[0001] The utility model belongs to the technical field of roasting machines, in particular to a sealing device for a belt sintering and pellet roasting machine. Background Art

[0002] Sintering or pelletizing is a crucial process in steelmaking, providing high-quality raw materials for blast furnace ironmaking. To improve energy efficiency during the sintering process, sintering and pelletizing professionals have been diligently exploring numerous solutions. However, most roaster sealing covers currently in use lack safety mechanisms. If the wire rope breaks, the sealing cover falls directly, posing a safety hazard during maintenance. Therefore, a sealing device for belt sintering and pelletizing roasters is needed to address this issue. Utility Model Content

[0003] Aiming at the problem that the current sealing cover of the roasting machine has no safety device and there is a potential safety hazard, the utility model provides a sealing device for a belt sintering and pellet roasting machine to improve the safety of the sealing cover.

[0004] The utility model is realized through the following technical solutions:

[0005] A sealing device for a belt sintering and pellet roasting machine is provided on both sides of a roasting machine trolley and comprises a support frame and a sealing cover;

[0006] The motor is fixed to the top of the support frame through the side plate, and a collecting roller is provided at the output end of the motor. A mounting plate is fixed to the side of the side plate away from the motor. The bottom of the back of the mounting plate is movably connected to the tail end of the sealing cover through a bearing. A limiting thorn wheel is also fixed to one side of the tail end of the sealing cover, and a plurality of limiting grooves are equidistantly provided around the limiting thorn wheel.

[0007] The middle part of the mounting plate is provided with a through slot in the vertical direction, and slide slots are provided on both sides of the through slot for placing a slider, and a spring is provided between the top of the slider and the top of the through slot; the slider is provided with a movably connected guide wheel on the front side of the mounting plate, and the slider is fixed with a connecting rod on the back side of the mounting plate, and a triangular limit block is provided at the end of the connecting rod, and the connecting rod is arranged vertically;

[0008] A steel wire rope is provided at the front end of the sealing cover to connect with the collecting roller, and the steel wire rope passes through the bottom of the guide wheel.

[0009] The working principle of this utility model is as follows:

[0010] When the roasting machine is working, the motor is started to drive the collecting roller to rotate. At this time, the wire rope is tightened, and the guide wheel is lifted upward by the wire rope, thereby driving the slider to slide upward in the through groove, squeezing the spring, and the connecting rod set on the back of the slider drives the limit block to be lifted upward and disengaged from the limit groove of the limit ratchet. The sealing cover is unlocked and can be rotated and lifted by the wire rope.

[0011] When the wire rope breaks, the guide wheel loses the upward force exerted by the wire rope on it, and the slider is pushed downward under the action of the spring force, thereby driving the connecting rod to clamp the limit block into the limit groove of the limit ratchet, thereby limiting the limit secondary wheel to prevent it from rotating, so that the sealing cover cannot rotate to avoid safety accidents.

[0012] As a further improvement of the present invention, reinforcing ribs are provided on both sides of the connecting rod on the back side of the mounting plate.

[0013] The reinforcing ribs can further restrict the connecting rod, preventing the connecting rod from being broken due to excessive force when driving the limit block to lock the limit ratchet, thereby further improving safety.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The utility model discloses a simple structure, is easy to operate, by arranging a limiting secondary wheel at the bottom end of the sealing cover, utilizing the elastic force of the wire rope when it is retracted to lift the guide wheel to drive the limiting block to separate from the limiting thorn wheel and thus unlock the lock; when a fault occurs, the wire rope breaks and the thrust limiting block is lost, and the limiting block automatically falls down and locks the limiting secondary wheel under the action of the spring elastic force, making the sealing cover unable to rotate, thus avoiding safety accidents and greatly improving safety.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings. In the embodiments, unless otherwise specified, the technical means used are conventional technical means in the art. Example 1

[0022] like Figure 1The sealing device of a belt sintering and pellet roasting machine shown is arranged on both sides of the roasting machine trolley 6 and includes a support frame 5 and a sealing cover 7;

[0023] The motor 2 is fixed to the top of the support frame 5 through the side plate 17, and the output end of the motor 2 is provided with a collecting roller 1. The side of the side plate 17 away from the motor 2 is fixed with a mounting plate 3. The bottom of the back of the mounting plate 3 is movably connected to the tail end of the sealing cover 7 through a bearing. A limiting thorn wheel 4 is also fixed to one side of the tail end of the sealing cover 7. A plurality of limiting grooves 16 are equidistantly provided around the limiting thorn wheel 4.

[0024] like Figure 2-3 As shown, a through slot 12 is provided in the middle of the mounting plate 3 in the vertical direction, and slide slots 11 are provided on both sides of the through slot 12 for placing a slider 9. A spring 8 is provided between the top of the slider 9 and the top of the through slot 12; the slider 9 is located on the front side of the mounting plate 3 and is provided with a movably connected guide wheel 10, and the slider 9 is located on the back side of the mounting plate 3 and is fixed with a connecting rod 13, and a triangular limit block 14 is provided at the end of the connecting rod 13, and the connecting rod 13 is set vertically;

[0025] A steel wire rope 18 is provided at the front end of the sealing cover 7 to connect with the collecting roller 1 , and the steel wire rope 18 passes through the bottom of the guide wheel 10 .

[0026] The working principle of this embodiment is as follows:

[0027] When the roasting machine is working, the starting motor 2 drives the collecting roller 1 to rotate. At this time, the wire rope 18 is tightened, and the guide wheel 10 is lifted upward by the wire rope 18, thereby driving the slider 9 to slide upward in the through groove 12, squeezing the spring 8, and the connecting rod 13 set on the back of the slider 9 drives the limit block 14 to be lifted upward and disengaged from the limit groove 16 of the limit ratchet 4. The sealing cover 7 is unlocked and can be rotated and lifted by the wire rope 18.

[0028] When the wire rope 18 breaks, the guide wheel 10 loses the upward force exerted by the wire rope 18, and the slider 9 is pushed downward by the elastic force of the spring 8, thereby driving the connecting rod 13 to clamp the limit block 14 into the limit groove 16 of the limit ratchet 4, thereby limiting the limit secondary wheel 4 to prevent it from rotating, so that the sealing cover 7 cannot rotate to avoid safety accidents. Example 2

[0029] This embodiment is a further improvement made on the basis of embodiment 1, and is specifically as follows:

[0030] The back side of the mounting plate 3 is provided with reinforcing ribs 15 on both sides of the connecting rod 13 .

[0031] The working principle of this embodiment is the same as that of embodiment 1. The reinforcing rib 15 can further limit the connecting rod 13 to prevent the connecting rod 13 from being broken due to excessive force when driving the limiting block 14 to lock the limiting ratchet 4, thereby further improving safety.
