Description

Technical Field

[0001] The utility model relates to the technical field of blockage clearing machine seals, in particular to a cavity-type carbon fiber combined seal component. Background Art

[0002] The rotary silo clearing machine is a new product developed specifically to solve the problem of raw coal sticking and blocking. Due to its rotatable characteristics, it solves the problem of raw coal sticking to and hanging on the inner wall of the coal hopper, loosens the pressure of the coal seam, and is not affected by climatic conditions, environmental factors, and coal quality. It can increase the fluidity of raw coal and has obvious clearing effects, greatly improving the coal supply capacity of the coal feeder, thereby avoiding the unit being forced to operate with oil.

[0003] After consulting the literature, we know that the rotary silo blockage clearer has played a vital role in the application field of coal powder transportation, greatly ensuring the anti-blocking effect during coal powder transportation. However, when the coal powder pipeline is docked, although the existing pipelines have a relatively good sealing effect after docking, the existing pipelines are usually docked with sealing gaskets and then fixed by auxiliary components. This method has the problem of relatively complicated installation during operation, and the pipeline needs to be separated when replacing the sealing gasket, which greatly reduces the efficiency of replacing the sealing gasket. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a cavity-type, carbon fiber combined sealing component that can solve the problem that pipes are usually butt-jointed with sealing gaskets and then fixed with auxiliary components, but this method is relatively complicated to install and requires separation of the pipes when replacing the sealing gaskets, which greatly reduces the efficiency of replacing the sealing gaskets.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cavity-type, carbon fiber combined sealing assembly, including an anti-blocking machine, a powder hose is fixedly connected to the surface of the anti-blocking machine, a connecting pipe is arranged at the end of the powder hose away from the anti-blocking machine, a first annular cavity is fixedly connected to the surface of the powder hose, a sliding rod is slidably connected to the inside of the first annular cavity, a second annular cavity is fixedly connected to the end of the sliding rod away from the first annular cavity, the inner side of the second annular cavity is fixedly connected to the surface of the connecting pipe, an inner ring is rotatably connected to the inside of the first annular cavity, an outer cavity ring is fixedly connected to the surface of the inner ring, and the inner side of the outer cavity ring is rotatably connected to the surface of the second annular cavity.

[0006] Preferably, a docking groove is provided on the surface of the powder tube, a docking tube is fixedly connected to the surface of the connecting tube, a fiber pad is provided on the inner wall of the docking groove, and the surface of the fiber pad abuts against the surface of the docking tube.

[0007] Preferably, an adjusting rod is slidably connected to the interior of the outer cavity ring, a first spring is slidably sleeved on the surface of the adjusting rod, and two ends of the first spring are respectively fixedly connected to the surface of the adjusting rod and the interior of the outer cavity ring.

[0008] Preferably, a slot is provided on the surface of the second annular cavity, and the lower end of the adjusting rod is slidably engaged with the inner wall of the slot.

[0009] Preferably, the outer side of the outer cavity ring is fixedly connected to an outer rod, the surface of the outer rod is slidably connected to an outer plate, the surface of the outer plate is slidably connected to the outer side of the outer cavity ring, the surface of the outer rod is slidably sleeved with a second spring, and the two ends of the second spring are respectively fixedly connected to the surface of the outer plate and the surface of the outer cavity ring.

[0010] Preferably, a positioning groove is provided on the inner side of the outer plate, and the upper side of the adjusting rod is clamped on the inner wall of the positioning groove.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The cavity-type, carbon fiber combined sealing assembly can only move a certain distance when the powder hose and the connecting pipe are limited by the sliding rod. At this time, the operator takes out the fiber pads on the opposite sides of the powder hose and the connecting pipe for replacement. When the replacement is completed, the connecting pipe only needs to drive the second ring cavity to reset so that the powder hose and the connecting pipe are docked. At this time, the operator controls the outer plate to squeeze the arc surface of the adjusting rod, so that the adjusting rod passes through the outer cavity ring and enters the inner wall of the card groove until the adjusting rod is carded with the positioning groove, and the powder hose and the connecting pipe are fixed. This method not only ensures the convenience of replacing the fiber pad, but also ensures that this sealing form can be replaced online without stopping the machine, which ensures convenient operation when replacing the fiber pad, reduces the cumbersomeness caused by the need to disassemble the connection between the connecting pipe and the powder hose when replacing the traditional fiber pad, and greatly improves the simplicity of fixing and separating the powder hose and the connecting pipe through the outer cavity ring on the powder hose and the connecting pipe.

[0013] The cavity-type, carbon fiber combined sealing component can displace the gap between the powder hose and the connecting pipe when docking by utilizing the docking groove provided on the powder hose and the docking pipe fixed on the connecting pipe. At this time, when the fiber pad is docked on the inner wall of the docking groove by squeezing the docking pipe, the fiber pad can also be docked by the staggered docking of the powder hose and the connecting pipe when the powder hose and the connecting pipe are docked. The staggered docking of the fiber pad at the docking point of the powder hose and the connecting pipe is achieved, thereby greatly improving the sealing effect of the docking between the powder hose and the connecting pipe, and maintaining the sealing of the docking point between the powder hose and the connecting pipe for a longer period of time without powder leakage, thereby reducing the number of times the fiber pad is replaced, and also ensuring the double sealing effect of the fiber pad combined sealing when the powder hose and the connecting pipe are cavity-type docked.

[0014] This cavity-type, carbon fiber combined sealing assembly, by arranging a slidable slide rod between the first ring cavity and the second ring cavity, not only achieves the effect that the powder hose and the connecting pipe do not need to be separated when replacing the fiber pad, but also ensures the accuracy of small-range movement and docking between the powder hose and the connecting pipe, thereby ensuring the convenience of docking and fixing between the powder hose and the connecting pipe.

Preferably, the material of the outer plate 16 is a carbon fiber aluminum plate. A second spring 17 is sleeved on the surface of the outer rod 15 along the setting direction of the outer rod. The two ends of the second spring 17 are respectively fixedly connected to the surface of the outer plate 16 and the surface of the outer cavity ring 11. Further, the elastic potential energy of the second spring 17 is greater than the elastic potential energy of the first spring 13. A concave positioning groove 18 is provided on the side of the outer plate 16 that is in sliding contact with the outer cavity ring 11, and the positioning groove 18 is a concave spherical surface. The upper end of the adjustment rod 12 is a spherical surface that matches the size of the positioning groove 18, and their positions are also corresponding.

[0028] Working principle: A cavity-type, carbon fiber combined sealing component. When the fiber pad 6 needs to be replaced, the operator only needs to control the outer plate 16 to move above the adjusting rod 12, and the adjusting rod 12 will slide out of the positioning groove 18. At this time, the outer plate 16 no longer forms an extrusion and limiting effect on the adjusting rod 12, and then the adjusting rod 12 is pushed by the elastic performance of the stretched first spring 13, and the first spring 13 drives the adjusting rod 12 to slide upward from the card groove 14. At this time, the operator controls the connecting pipe 3 to drive the second ring cavity 9 to slide on the inner side of the outer cavity ring 11. Out, and then through the limit of the sliding rod 8, the powder hose 2 and the connecting pipe 3 will only move a certain distance. At this time, the operator will take out the fiber pad 6 on the opposite side of the powder hose 2 and the connecting pipe 3 for replacement. When the replacement is completed, it is only necessary for the connecting pipe 3 to drive the second annular cavity 9 to reset so that the powder hose 2 and the connecting pipe 3 are connected.
