Technical Field

[0001] This utility model relates to the field of pipeline transportation technology, specifically a material conveying pipeline with an anti-abrasion lining. Background Technology

[0002] Material conveying pipelines are pipeline systems used to transport solid particles, powders, liquids, or gases. They are widely used in industries such as mining, metallurgy, papermaking, power, chemicals, and building materials. The design and construction of material conveying pipelines are based on various factors, including the properties of the conveyed material, the conveying method, flow rate, pressure, temperature, and abrasiveness.

[0003] Currently, for conveying granular or semi-dry materials, pipes with special lining materials are used to reduce wear on the inner wall of the pipe. These pipes consist of a metal pipe with a wear-resistant and corrosion-resistant material lining the inner wall to extend the pipe's service life and reduce maintenance and replacement costs.

A rotating shaft seat 13 with the same central axis as the outer metal tube 10 is provided in the middle of the extension rods 12. An upward-opening through groove 14 is provided through the rotating shaft seat 13. The outer walls of the extension rods 12 and the rotating shaft seat 13 are lined with an anti-wear material of the same material as the inner lining tube 11.

[0038] The inner liner 11 and the outer metal tube 10 are both sealed with elbows. The outer layer of the elbow is a metal layer, and the inner wall of the metal layer is lined with an anti-wear layer of the same material as the inner liner 11. Figure 3 , Figure 4 , Figure 5As shown, it includes: a 90-degree elbow 31, a 180-degree elbow 32, and a 45-degree elbow 33; the inner walls of the protruding sides of the 90-degree elbow 31, 180-degree elbow 32, and 45-degree elbow 33 are provided with threading lugs 30, which are fixedly connected to the metal part of the elbow. The threading lugs 30 are lined with an anti-friction material of the same material as the inner liner tube 11 for threading a transmission rope, and the transmission rope is made of a flexible material; at least one threading lug 30 is provided in each of the 90-degree elbow 31 and the 45-degree elbow 33. When only one threading lug 30 is provided, the threading lug 30 is located on the symmetrical center line of the 90-degree elbow 31 and the 45-degree elbow 33; at least two threading lugs 30 are provided in the 180-degree elbow 32. When only two threading lugs 30 are provided, the threading lugs 30 are symmetrically located on both sides of the symmetrical center line of the 180-degree elbow 32.

[0039] like Figure 2 As shown, a disc-shaped tension spring 20, which is connected to the transmission rope and the conveying pump shaft, is rotatably inserted into the inner liner tube 11. The disc-shaped tension spring 20 is spaced apart from the inner wall of the inner liner tube 11. A disc-shaped fixing seat 21 is provided at both ends of the disc-shaped tension spring 20. A through rod 22, a rotating shaft 23, and a top 25 are coaxially extended from the center of the outer end face of the fixing seat 21 in sequence.
