By arranging the cavity structure formed by combining the pulverized coal conveying pipe, the circumferential partition plate and the fan-shaped expansion rubber piece, if the pulverized coal is hardened in the pulverized coal conveying process, the hardened pulverized coal is adhered to the inner side of the fan-shaped expansion rubber piece, and at the moment, the pulverized coal is prevented from being hardened. High-pressure air only needs to be conveyed into a cavity formed by combining the pulverized coal conveying pipe, the circumferential partition plate and the fan-shaped expansion rubber pieces through operation of an external air pump, the fan-shaped expansion rubber pieces deform and expand, then pulverized coal bonded to the inner sides of the fan-shaped expansion rubber pieces is broken and falls off, and the pulverized coal is conveyed into the cavity through control over sequential expansion and contraction of the multiple fan-shaped expansion rubber pieces. Therefore, all-directional anti-blocking disturbance of the pulverized coal conveying pipe can be realized.

Description

Technical Field

[0001] The utility model relates to the technical field of coal powder pipeline anti-blocking, in particular to a coal powder pipeline anti-blocking disturbance device. Background Art

[0002] A pulverized coal pipeline is a pipeline used to transport pulverized coal. It is usually composed of an inner rubber layer, a multi-layer cloth-wrapped layer and an outer rubber layer. It has good wear resistance, corrosion resistance and high temperature resistance, and can withstand the impact of high-pressure and high-speed flowing pulverized coal particles.

[0003] When a pulverized coal pipeline is transporting pulverized coal, if the water content of the transported pulverized coal is high, dead corners and compaction are likely to occur, which in turn leads to blockage inside the pulverized coal pipeline. Based on this, a pulverized coal pipeline anti-blocking disturbance device is provided. Utility Model Content

[0004] The purpose of the utility model is to provide a pulverized coal pipeline anti-blocking disturbance device in order to solve the problems in the above background.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a pulverized coal pipeline anti-blocking and disturbance device, comprising a pulverized coal conveying pipe, a circumferential partition plate fixedly connected to the inner side of the pulverized coal conveying pipe, a plurality of circumferential partition plates being provided, the plurality of circumferential partition plates being evenly distributed along the circumferential direction, a sector-shaped expansion rubber piece fixedly connected between two adjacent circumferential partition plates, a cavity structure being formed by the combination of the pulverized coal conveying pipe, the circumferential partition plate, and the sector-shaped expansion rubber piece, and a ventilation pipe head in communication with the cavity structure being fixedly connected to the outer side of the pulverized coal conveying pipe;

[0006] The ventilation pipe head is connected to the air pump through an external pipeline. The air pump is used to deliver high-pressure air into the cavity to expand the fan-shaped expansion film, thereby loosening and breaking the coal powder compacted inside the fan-shaped expansion film, thereby preventing blockage and disturbance of the coal powder conveying pipe.

[0007] As a further solution of the present invention: the inner wall of the coal powder conveying pipe is located at both ends of the circumferential partition plate and the fan-shaped expansion rubber sheet, and horizontal annular partitions are fixedly connected. The interior of a single coal powder conveying pipe is evenly provided with multiple groups of circumferential partition plates and fan-shaped expansion rubber sheets along the long side direction of the coal powder conveying pipe.

[0008] As a further solution of the present invention: ventilation pipe heads matching the number of fan-shaped expansion films are provided on the outside of the coal powder conveying pipe, and the external pipes connected to the plurality of ventilation pipe heads are controlled to be connected and cut off by electronic valves.

[0009] As a further solution of the present invention, the initial air pressure inside the cavity structure composed of the pulverized coal conveying pipe, the circumferential partition plate, the fan-shaped expansion rubber sheet and the horizontal annular partition plate is greater than the air pressure of the pulverized coal conveying pipe.

[0010] As a further solution of the present invention: connecting flanges are symmetrically fixed at both ends of the pulverized coal conveying pipe, and two adjacent pulverized coal conveying pipes are connected and fixed by the connecting flanges and bolts;

[0011] Both ends of the pulverized coal conveying pipe are fixedly connected with horizontal annular partitions.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By setting up a cavity structure composed of a coal powder conveying pipe, a circumferential partition plate, and a fan-shaped expansion film, during the coal powder conveying process, if the coal powder becomes compacted, the compacted coal powder will adhere to the inner side of the fan-shaped expansion film. At this time, it is only necessary to use an external air pump to deliver high-pressure air to the inside of the cavity composed of the coal powder conveying pipe, the circumferential partition plate, and the fan-shaped expansion film. The fan-shaped expansion film will deform and expand, and then the coal adhered to the inner side of the fan-shaped expansion film will be shattered and fall off. By controlling the expansion and contraction of multiple fan-shaped expansion films in sequence, the coal powder conveying pipe can be fully prevented from blocking and disturbance.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1 to 3In an embodiment of the utility model, a pulverized coal pipeline anti-blocking and disturbance device includes a pulverized coal conveying pipe 1, a circumferential partition plate 3 is fixedly connected to the inner side of the pulverized coal conveying pipe 1, a plurality of circumferential partition plates 3 are provided, and the plurality of circumferential partition plates 3 are evenly distributed along the circumferential direction, a sector-shaped expansion rubber sheet 4 is fixedly connected between two adjacent circumferential partition plates 3, a cavity structure is formed by the combination of the pulverized coal conveying pipe 1, the circumferential partition plates 3, and the sector-shaped expansion rubber sheet 4, and a ventilation pipe head 6 that is in conduction with the cavity structure is fixedly connected to the outer side of the pulverized coal conveying pipe 1;

[0020] The vent pipe head 6 is connected to the air pump through an external pipe. The air pump delivers high-pressure air into the cavity to expand the sector-shaped expansion film 4, thereby loosening and breaking the coal powder compacted inside the sector-shaped expansion film 4, thereby preventing the coal powder conveying pipe 1 from being blocked and disturbed.

[0021] Ventilation pipe heads 6 are provided on the outside of the pulverized coal conveying pipe 1 in a number matching the number of sector-shaped expansion films 4, and the external pipelines connected to the plurality of ventilating pipe heads 6 are controlled to be connected and disconnected by electronic valves.

[0022] In this embodiment, when the pulverized coal conveying pipe 1 is in use, the inner pipe wall is composed of a plurality of sector-shaped expansion films 4. During the pulverized coal conveying process, if the pulverized coal becomes compacted, the compacted pulverized coal will adhere to the inner side of the sector-shaped expansion films 4. At this time, it is only necessary to operate an external air pump to deliver high-pressure air into the cavity formed by the pulverized coal conveying pipe 1, the circumferential partition plate 3, and the sector-shaped expansion films 4 to increase the air pressure in the cavity. The sector-shaped expansion films 4 deform and expand under this pressure, and then the coal adhered to the inner side of the sector-shaped expansion films 4 is pulverized and falls off. After that, the conveying airflow of the pulverized coal conveying pipe 1 is connected, and the airflow can blow away the fallen pulverized coal, thereby achieving the anti-clogging function of the pulverized coal conveying pipe 1.

[0023] By controlling the expansion and contraction of the plurality of sector-shaped expansion films 4 in sequence, the pulverized coal conveying pipe 1 can be prevented from being blocked in all directions.

[0024] Please refer to Figures 1 to 3 The inner wall of the pulverized coal conveying pipe 1 is located at both ends of the circumferential partition plate 3 and the sector-shaped expansion rubber 4, and a horizontal annular partition plate 5 is fixedly connected. The interior of a single pulverized coal conveying pipe 1 is evenly provided with multiple groups of circumferential partition plates 3 and sector-shaped expansion rubber 4 along the long side direction of the pulverized coal conveying pipe 1;

[0025] Connecting flanges 2 are symmetrically fixed at both ends of the pulverized coal conveying pipe 1, and two adjacent pulverized coal conveying pipes 1 are connected and fixed by the connecting flanges 2 and bolts;

[0026] Both ends of the pulverized coal conveying pipe 1 are fixedly connected with horizontal annular partitions 5.

[0027] In this embodiment, the multiple groups of circumferential partition plates 3 and sector-shaped expansion films 4 of the pulverized coal conveying pipe 1 are separated by a horizontal annular partition plate 5. When the multiple ventilation pipe heads 6 are sequentially connected, the multiple sector-shaped expansion films 4 can be sequentially expanded, thereby achieving the anti-clogging function of the pulverized coal conveying pipe 1.

[0028] Moreover, each pulverized coal conveying pipe 1 can be independently controlled, so that the conveying pipeline can be better managed.

[0029] Please refer to Figures 1 to 3 The initial air pressure inside the cavity structure composed of the pulverized coal conveying pipe 1, the circumferential partition plate 3, the fan-shaped expansion rubber sheet 4, and the horizontal annular partition plate 5 is greater than the air pressure of the pulverized coal conveying pipe 1.

[0030] In this embodiment, this structure can ensure that the fan-shaped expansion film 4 maintains a stable arc state under normal conditions, thereby ensuring stable coal powder transportation.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
