Embodiment 1

[0039] Such as figure 1 As shown, the heterogeneous segmented high wear-resistant double-layer straight pipe of the concrete pump truck in this embodiment consists of a protective outer pipe 1, a wear-resistant connecting flange 2, a segmented heterogeneous wear-resistant inner pipe 3 and a shock-absorbing filling cavity 4. In this embodiment, the protective outer pipe 1 is a welded steel pipe with a weld 1-1 on it; the segmented heterogeneous wear-resistant inner pipe 3 is composed of a filling channel 3-1 and a wear-resistant left end The inner tube 3-2, the middle wear-resistant inner tube 3-3 and the right end wear-resistant inner tube 3-4 are composed; the segmented heterogeneous wear-resistant inner tube 3 is installed inside the protective outer tube 1, and the wear-resistant connecting flange 2 The two ends of the protective outer tube 1 and the segmented heterogeneous wear-resistant inner tube 3 are designed to be packaged and reinforced by welding, and the shock-abso...

Embodiment 2

[0047] Such as Figure 5 As shown, in this embodiment, the main structure of the straight pipe is the same as that of Embodiment 1. It’s just that the segmented heterogeneous wear-resistant inner tube 3 is composed of a filling channel 3-1, a wear-resistant inner tube 3-2 at the left end, a wear-resistant inner tube 3-3 at the middle part, and a wear-resistant inner tube 3-4 at the right end; Grinding inner tube 3-3 is two or more; Between the wear-resistant inner tube 3-2 of the left end and the wear-resistant inner tube 3-3 of the middle part, the wear-resistant inner tube 3-4 of the right end part and the wear-resistant inner tube of the middle part A filling channel 3-1 is provided between the tubes 3-3 or between two adjacent wear-resistant inner tubes 3-3 in the middle (filling channels can also be provided); the wear-resistant inner tube 3-2 at the left end and the wear-resistant inner tube in the middle The tube 3-3 and the wear-resistant inner tube 3-4 at the right e...

Embodiment 3

[0053] In this embodiment, the basic structure of the straight pipe is the same as in Embodiment 1, but a specific wear-resistant connecting flange is provided. Such as Figure 6 As shown, the wear-resistant connecting flange 2 is composed of a flange 2-1 and a wear-resistant sleeve 2-2; the wear-resistant sleeve 2-2 is installed inside the flange 2-1.

[0054] The flange 2-1 in the present invention refers to: a component of the wear-resistant connecting flange 2; its function is to facilitate the connection and installation of straight pipes and other equipment.

[0055] The wear-resistant sleeve 2-2 of the present invention refers to: wear-resistant materials such as high-chromium cast iron, low-chromium cast iron, medium-chromium cast iron, wear-resistant cast iron, alloy steel, bearing steel, ceramics, hard alloy, polymer materials, etc. A wear-resistant sleeve made of one of them; its function is to prolong the service life of the wear-resistant connecting flange 2 and ...

Abstract

The invention discloses a heterogeneous sectional-type high abrasion resistant double-layer straight pipe used for concrete conveying. The double-layer straight pipe comprises a protective outer pipe (1) and a sectional-type heterogeneous abrasion resistant inner pipe (3). The sectional-type heterogeneous abrasion resistant inner pipe (3) is nested in the protective outer pipe (1). The sectional-type heterogeneous abrasion resistant inner pipe (3) comprises two or more abrasion resistant inner pipe sections connected mutually in order. The sectional-type heterogeneous abrasion resistant inner pipe (3) at least comprises the left end inner pipe section (3-2), the right end inner pipe section (3-4) and the one or more middle inner pipe sections (3-3). According to the abrasion resistant straight pipe, the service life of a pipeline can be greatly prolonged, and the ratio of the price to performance of the pipeline is increased by a certain times or above. Large batches of production are easy to achieve, the quality is stable and reliable, and safety performance is high.

Description

technical field [0001] The invention relates to a wear-resistant double-layer straight pipe structure for conveying fluid state materials, in particular to a heterogeneous segmented high wear-resistant double-layer straight pipe used for concrete conveyance. Background technique [0002] Wear-resistant pipeline transportation has been widely used in electric power, metallurgy, coal, petroleum, chemical industry, building materials, machinery and other industries. When transporting abrasive materials (such as ash, coal powder, ore powder, etc.) There is a problem that the wear-resistant pipeline wears quickly. When the gas, liquid or solid with strong corrosion is transported in the wear-resistant pipeline, there is a problem that the wear-resistant pipeline is corroded and quickly destroyed; when the wear-resistant pipeline is transported with high temperature When using high-quality materials, there is a problem that the use of heat-resistant steel pipes is very expensive; ...
