Description

Technical Field

[0001] The utility model relates to the technical field of sintering machine trolleys, and in particular to an air leakage prevention device at the end of a sintering machine trolley. Background Art

[0002] The sintering machine trolley end is a device that smoothly guides the raw material into the sintering machine for sintering. The sintering machine trolley end feeds the raw material into the sintering machine and sintered it into pellets. The ore sintered into pellets has better mechanical strength and wear resistance. The sintering machine trolley end needs to be in a closed state when working. Even the air leaking in will affect the temperature and other parameters of the sintering machine trolley end, thereby reducing the sintering efficiency;

[0003] At present, the method of isolating the end of the sintering machine trolley is generally to isolate the end of the sintering machine trolley by using a partition to reduce the impact on the end of the sintering machine trolley and make the parameter error of the end of the sintering machine trolley lower;

[0004] However, since the end of the sintering machine trolley is relatively large, a larger baffle is needed to close the end of the sintering machine trolley. When the end of the sintering machine trolley needs to be maintained, it is troublesome to separate the baffle from the end of the sintering machine trolley due to its large size and heavy weight, so the staff needs to make improvements. Utility Model Content

[0005] The purpose of the utility model is to overcome the problem that multiple baffles in the prior art will form multiple leaks when combined, and thus provide a sintering machine trolley end anti-air leakage device;

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] include:

[0008] A bottom plate, the front and rear sides of the top of the bottom plate are both slidably connected with sliding plates, the front of the top of the sliding plate is fixedly connected with a first partition plate, the tail of the first partition plate is fixedly connected with a first connecting card plate, the tail of the top of the sliding plate is fixedly connected with a second partition plate, the front of the second partition plate is fixedly connected with a second connecting card plate, the front of the second connecting card plate is fixedly connected with a plug-in board, and the surface of the plug-in board is plugged into the inner wall of the first connecting card plate, and the fronts of the first partition plate and the second partition plate are both fixedly connected with handles.

[0009] The left and right sides of the inner top wall of the sliding plate are both fixedly connected with a rotating rod, and the bottom end of the rotating rod is rotatably connected with a roller.

[0010] The upper and lower ends of the left and right sides of the first connecting card plate are fixedly connected with telescopic rods, the front end of the telescopic rods is plugged with a connecting box, the middle parts of the two groups of connecting boxes are fixedly connected with limiting rings, the middle parts of the limiting rings are rotatably connected with connecting blocks, the front of the connecting block is fixedly connected with a pull ring, the tail of the connecting block is fixedly connected with a screw, and the surface of the screw is threadedly connected to the inner wall of the first connecting card plate and the plug-in plate.

[0011] The first connection card plate is identical to the second connection card plate, so that after the plug board is inserted into the first connection card plate, the first connection card plate and the second connection card plate can fit together, thereby making it difficult for wind to blow into the inner wall.

[0012] The left and right sides of the sliding plate are both semicircular, and the groove for sliding the sliding plate opened on the top of the bottom plate is equal to the horizontal longitudinal section of the sliding plate, so that the groove opened on the bottom plate limits the sliding direction of the first partition.

[0013] The bottoms of the first partition plate and the second partition plate fit with the top of the bottom plate, so that less air can pass through the bottoms of the first partition plate and the second partition plate.

[0014] The technical solution provided by the utility model has the following technical effects:

[0015] 1. The utility model provides a sintering machine trolley end anti-air leakage device, which makes the first partition and the second partition unable to rise by inserting the sliding plates at the bottom of the first partition and the second partition into the groove at the top of the bottom plate. When the sintering machine trolley end needs to be isolated, the first partition and the second partition are pushed from the outside to the middle, so that the plug-in plate is inserted into the first connecting card plate, thereby isolating the sintering machine trolley end. When the sintering machine trolley end needs to be checked, the first partition and the second partition can be pulled to both sides so that the two can be slid apart for inspection. This device has fewer gaps, so that less air leaks in, and the sintering machine trolley end can be checked and maintained by pushing and pulling the first partition and the second partition, thereby achieving the effect of conveniently opening the partition to check the sintering machine trolley end.

[0016] 2. The utility model provides a sintering machine trolley end anti-air leakage device, which can fix the first partition plate and the second partition plate through a screw by rotating the pull ring. When the screw is rotated to separate from the first connecting clamping plate, the telescopic rod and the limiting ring effectively limit the screw to prevent the screw from falling and being lost, thereby achieving the effect of effectively preserving the screw.

[0027] Circular grooves are provided on both the left and right sides of the first partition plate 3 and the second partition plate 5, and cotton pads are installed in the circular grooves, so that the output line of the sintering machine trolley end can be extended through the circular grooves, and the output line can be wrapped with the cotton pads to effectively reduce the air leakage rate;

[0028] Fix the bottom plate 1 at the position where the sintering machine trolley end head needs to be installed, then place the sintering machine trolley end head on the top of the bottom plate 1 and install it, then push the two sliding plates 2 through the grooves on the top of the bottom plate 1, and then when the sintering machine trolley end head needs to be closed, push the first partition plate 3 and the second partition plate 5 toward the middle, so that the sliding plate 2 drives the top first partition plate 3 and the second partition plate 5 to slide to the middle, and make the plug-in plate 7 contact the first connecting card plate 4, so that the plug-in plate 7 is inserted into the inner wall of the first connecting card plate 4, and the first connecting card plate 4 is fit with the second connecting card plate 6, and then fixed again, so that the sintering machine trolley end head can be closed, and when the sintering machine trolley end head needs to be checked, the first partition plate 3 and the second partition plate 5 are unfixed, and then the handle 8 is held and pulled backward, so that the first partition plate 3 and the second partition plate 5 slide outward, thereby exposing the sintering machine trolley end head to the outside, so that it can be easily inspected and maintained;

[0029] The left and right sides of the inner top wall of the sliding plate 2 are fixedly connected with a rotating rod 9, and the bottom end of the rotating rod 9 is rotatably connected with a roller 10;

[0030] When the first partition 3 and the second partition 5 are pushed and pulled forward and backward, the sliding plate 2 drives the rotating rod 9 at the bottom to move, and the rotating rod 9 drives the roller 10 at the bottom to move forward and backward, so that the staff can push and pull the first partition 3 and the second partition 5 more easily;

[0031] The upper and lower ends of the left and right sides of the first connecting card plate 4 are fixedly connected with telescopic rods 11, the front end of the telescopic rods 11 is plugged with a connection box 12, the middle parts of the two groups of connection boxes 12 are fixedly connected with a limiting ring 13, the middle part of the limiting ring 13 is rotatably connected with a connecting block 14, the front of the connecting block 14 is fixedly connected with a pull ring 15, the tail of the connecting block 14 is fixedly connected with a screw 16, and the surface of the screw 16 is threadedly connected to the first connecting card plate 4 and the inner wall of the plug-in board 7;

[0032] When the first partition 3 and the second partition 5 need to be fitted and fixed, the tail end of the screw 16 is touched to the first connecting card plate 4, and then the pull ring 15 is rotated so that the pull ring 15 drives the front screw 16 to rotate, so that the screw 16 rotates through the first connecting card plate 4 and the plug-in board 7, and the connecting block 14 drives the surface limiting ring 13 to move toward the first connecting card plate 4, and the limiting ring 13 drives the upper and lower sides of the connecting box 12 to move, so that the telescopic rod 11 shrinks into the inner wall of the connecting box 12, thereby fixing the first partition 3 and the second partition 5. When the first partition 3 and the second partition 5 need to be opened, the pull ring 15 is rotated in the opposite direction to disengage the screw 16 from the outside of the first connecting card plate 4, thereby disengaging the first partition 3 and the second partition 5 from being fixed while preventing the screw 16 from being lost.

[0033] Working principle: fix the bottom plate 1 at the position where the sintering machine trolley end head needs to be installed, then place the sintering machine trolley end head on the top of the bottom plate 1 and install it. Then, when the sintering machine trolley end head needs to be closed, push the first partition plate 3 and the second partition plate 5 toward the middle, so that the roller 10 drives the first partition plate 3 and the second partition plate 5 to move to the middle, so that the plug-in board 7 is inserted into the inner wall of the first connecting card plate 4, and the first connecting card plate 4 and the second connecting card plate 6 are fitted together, and then the screw 16 touches the first connecting card plate 4. A connecting card plate 4 is used to rotate the pull ring 15 to fix the first partition plate 3 and the second partition plate 5. When the sintering machine trolley end needs to be inspected and maintained, the pull ring 15 is rotated in the opposite direction to disengage the screw 16 from the first connecting card plate 4. Then, the handle 8 is held and pulled outward to make the first partition plate 3 and the second partition plate 5 drive the rollers 10 to move to both sides, thereby separating the first partition plate 3 from the second partition plate 5 and exposing the sintering machine trolley end to the outside, so that the sintering machine trolley end can be easily inspected and maintained.
