Description

Technical Field

[0001] The invention belongs to the technical field of industrial transportation, and particularly relates to a powder solid transportation pipeline, a device and a working method thereof. Background Art

[0002] When transporting powder solids through a pneumatic pipeline, factors such as changes in the flow rate (velocity) of the transported solids, changes in ambient temperature, and changes in the moisture content of the solids can cause the transported powder solids to clog and cake in the pipeline. After the pipeline is clogged, it is mostly cleared by external means such as poking the pipe, and the cleaning is difficult. The traditional method has a poor dredging effect and is difficult to dredge serious blockages. Finally, only the method of damaging the pipeline can be used for dredging, resulting in a high cost of the pipeline. Summary of the Invention

[0041] Embodiment

[0042] Please refer to Figures 1-3 , in this embodiment, the powder solid conveying pipeline includes a conveying pipeline 1, and a plurality of branch pipelines 2 are welded on the surface of the conveying pipeline 1. The plurality of branch pipelines 2 are spaced along the length direction of the conveying pipeline 1. The ends of the branch pipelines 2 can be installed with a first flange 3 and a second flange 7 through bolts. Limiting grooves 6 are opened on the end faces of the branch pipelines 2 and the surfaces of the first flanges 3, and sealing rubber rings 5 are installed inside the limiting grooves 6. A blind plate 4 is installed at the middle position of the sealing rubber ring 5; the second flange 7 includes an end plate 7-1 and a clogging clearing device arranged on the inner surface of the end plate 7-1, and the clogging clearing device is located inside the branch pipeline 2. In this implementation scheme, through the sealing rubber ring 5 installed in the limiting groove 6 opened between the branch pipeline 2 and the first flange 3, and at the same time the blind plate 4 is installed in the middle of the sealing rubber ring 5, it is convenient for the blind plate 4, the sealing rubber ring 5 and the limiting groove 6 to cooperate to tightly seal the connection between the branch pipeline 2 and the first flange 3, thereby increasing the tightness of the connection between the branch pipeline 2 and the first flange 3. At the same time, the clogging clearing device arranged on the surface of the end plate 7-1 of the second flange 7 is located inside the branch pipeline 2, which is convenient for the clogging clearing device to be connected to an external power source to clean the blockage inside the conveying pipeline 1, thereby improving the convenience of pipeline cleaning. Specifically, the clogging clearing device includes a first electric telescopic rod 8 installed on the upper surface of the end plate 7-1 (in the orientation shown in Figure 1 and Figure 3 ), a second electric telescopic rod 9 fixed to the telescopic end of the first electric telescopic rod 8, and an electric spiral drill bit 10 fixed to the telescopic end of the second electric telescopic rod 9. The telescopic end of the first electric telescopic rod 8 is perpendicular to the telescopic end of the second electric telescopic rod 9. A spiral blade is arranged outside the electric spiral drill bit 10, and the cross section of the sealing rubber ring 5 is a "C" shaped structure. In this embodiment, through the clogging clearing device composed of the first electric telescopic rod 8, the second electric telescopic rod 9 and the electric spiral drill bit 10, and at the same time the second electric telescopic rod 9 is installed at the telescopic end of the first electric telescopic rod 8, and the electric spiral drill bit 10 is installed at the telescopic end of the second electric telescopic rod 9, it is convenient to adjust the height of the electric spiral drill bit 10 when the first electric telescopic rod 8 extends and retracts, and the second electric telescopic rod 9 extends and retracts to adjust the depth of the electric spiral drill bit 10, so as to facilitate the clearing of blockages in the conveying pipeline 1.

[0043] The working principle and usage process of the powder solid conveying pipeline of the present invention are as follows:

[0044] In use, the first flange 3 is installed at the end of the branch pipe 2. Meanwhile, the branch pipe 2 and the first flange 3 are sealed through a blanking plate 4, a sealing rubber ring 5 and a limiting groove 6. When the conveying pipe 1 is blocked by internal solids, the first flange 3 is removed from the end of the branch pipe 2, and the second flange 7 is installed at the end of the branch pipe 2. At this time, the first electric telescopic rod 8, the second electric telescopic rod 9 and the electric spiral drill bit 10 are located inside the branch pipe 2. Connect the first electric telescopic rod 8, the second electric telescopic rod 9 and the electric spiral drill bit 10 to an external power source. At this time, the first electric telescopic rod 8 drives the second electric telescopic rod 9 to move first, and finally the second electric telescopic rod 9 drives the electric spiral drill bit 10 to extend and retract. Meanwhile, when the electric spiral drill bit 10 rotates, it clears the blockage inside the conveying pipe 1. The branch pipe 2 on the surface of the conveying pipe 1 can replace the first flange 3 for plugging at any time according to the usage needs, or replace the second flange 7 for pipe blockage cleaning.

[0045] As can be seen from the above, the powder solid conveying pipe of the present invention has the following characteristics:

[0046] 1. The first flange or the second flange can be replaced according to the usage of the conveying pipe through the branch pipes arranged at intervals on the conveying pipe. During normal use, the first flange is arranged and plugged with a blanking plate to reduce the leakage of the conveying pipe; when blocked, replace the second flange with a blockage cleaning device to dredge the pipe. The replaceable design reduces investment and increases the operating stability of the equipment.

[0047] 2. Through the sealing rubber ring installed in the limiting groove opened between the branch pipe and the first flange, and the blanking plate is installed in the middle of the sealing rubber ring, it is convenient for the blanking plate, the sealing rubber ring and the limiting groove to cooperate to only plug the connection between the branch pipe and the first flange, thereby increasing the tightness of the connection between the branch pipe and the first flange. Meanwhile, the blockage cleaning device arranged on the surface of the second flange is located inside the branch pipe, which is convenient for cleaning the blockage inside the conveying pipe after connecting the blockage cleaning device to an external power source, thus improving the convenience of pipe cleaning.

[0048] 3. Through the blockage cleaning device composed of the first electric telescopic rod, the second electric telescopic rod and the electric spiral drill bit, and the second electric telescopic rod is installed at the telescopic end of the first electric telescopic rod, and the electric spiral drill bit is installed at the telescopic end of the second electric telescopic rod, it is convenient to adjust the height of the electric spiral drill bit when the first electric telescopic rod extends and retracts, and the second electric telescopic rod extends and retracts to adjust the depth of the electric spiral drill bit, so as to facilitate the blockage cleaning of the conveying pipe.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
