Problems solved by technology

However, due to the special structure of the unconventional structure pipeline, it generally needs to be rolled or pressed, so it is difficult to use wear-resistant materials for forming, and the cost of using wear-resistant castings is relatively high and the production cycle is relatively long

Embodiment Construction

[0023] The following specific examples illustrate the implementation of the present invention. Those familiar with the technology can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0024] Such as Figure 1-3 As shown, a pipeline with an unconventional structure includes a pipeline 1. The pipeline 1 is composed of an outer wall 101 and an inner tube 107. The diameter of the inner tube 107 of the pipeline 1 gradually decreases from the right opening to the bottom end. The outer wall 101 is on the outer wall There are reinforcing ribs 10, multiple sets of parallel vertical support plates 102 are provided under the outer wall 101, and a bottom plate 103 is connected under the support plates 102 of the same height, which increases the overall stability and facilitates installation and fixation, especially during hauling , To prevent rolling; the right opening of the pipe 1 is provided with a flange 11 for eas...

Abstract

The invention discloses an unconventional-structure pipeline and a manufacturing method thereof. The unconventional-structure pipeline comprises a pipeline body. The pipeline body is composed of an outer wall and an inner pipe. The outer wall is in a quadrangular frustum pyramid shape, a hoop is arranged in the middle of the outer wall, a pair of lifting lugs are arranged on the left side and the right side of the upper portion of the outer wall, and a reinforcing plate is arranged between the lifting lugs. A first lining plate is arranged in the inner pipe of the pipeline body, a bolt hole is formed in the first lining plate, an annular groove is formed in the position, at the edge of the bolt hole, of the first lining plate, an installation hole is formed in the corresponding position, below the bolt hole in the first lining plate, of the pipeline body, the pipeline body and the first lining plate are connected by installing a bolt in the bolt hole and the installation hole, the first lining plate is formed by splicing lining plate blocks, a second lining plate is connected to the first lining plate on the pipeline body through an adhesive layer, and grooves are formed in the second lining plate. The unconventional-structure pipeline has the advantages of being stable in structure, high in safety coefficient, convenient to carry, assemble and disassemble, convenient to replace at a later stage, resistant to wear and good in anti-impact effect.

Description

Technical field [0001] The invention relates to a pipeline with an unconventional structure and a manufacturing method thereof. Background technique [0002] It is used in mines, concentrates, tailings and slurry transportation pipelines, coal-fired power plants ash transportation pipelines, and liquid transportation pipelines with solid particles in chemical systems. Generally, pipelines have high requirements for wear resistance. Unconventional pipeline structures are often encountered in the production of foreign mining machinery products, and such pipelines also have certain wear resistance requirements. Generally, the internal wear resistance of the pipeline is realized by the following two methods: 1. The internal integral liner is lined with wear-resistant rubber; 2. The internal wear-resistant material liner or wear-resistant castings are installed. Considering the short service life of the internal wear-resistant structure and frequent replacement, for the internal wear...
