Description

Technical Field

[0001] The utility model relates to a vertically arranged dust removal pipeline, belonging to the technical field of raw material conveying equipment in the metallurgical industry. Background Art

[0002] There are many dust removal pipelines and gas-material separation pipelines in the metallurgical industry, and their main function is to discharge or collect dust and particulate matter generated during the operation of industrial equipment. These pipelines are arranged vertically. During the dust removal or gas-material separation process, when solid particles flow from top to bottom at various angles, the granular solids in the pipeline will cause friction and collision with the pipeline body, causing pipeline damage and air leakage, affecting production. In addition, after the pipeline is damaged and leaks, it is necessary to cut and remove the damaged and leaking pipeline and replace it with a new one. Frequent replacement causes material waste. Utility Model Content

[0003] The utility model aims to provide a vertically arranged dust removal duct, which can reduce the friction and impact of particles on the duct body, avoid duct damage and air leakage, extend the service life of the duct, and solve the problems existing in the background technology.

[0004] The technical solution of the utility model is:

[0005] A vertically arranged dust removal duct comprises a duct body, an axial rib plate and a circumferential rib plate. The duct body is arranged vertically, and a plurality of circumferential rib plates arranged up and down are provided in the duct body. The plurality of circumferential rib plates are connected together by a plurality of axial rib plates.

[0006] The circumferential rib plate is annular, welded to the inner wall of the pipe body, and inclined upward at a certain angle.

[0007] The angle between the circumferential rib plate and the inner wall of the pipe body is 60°.

[0008] The circumferential rib spacing is 80-120 mm.

[0009] The axial rib plate is rectangular, with a length the same as that of the pipe body and a width matching that of the circumferential rib plate.

[0010] With the utility model, when solid particles flow from top to bottom at various angles, some of the solid particles accumulate between the circumferential rib plate and the pipeline body, and the solid particles that fall again will impact the accumulated particles between the circumferential rib plate and the pipeline body, forming material collision, thereby extending the life of the pipeline.

[0011] The beneficial effects of the utility model are: it can reduce the friction and impact of particles on the pipeline body, avoid pipeline damage and air leakage, and extend the service life of the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is an overall three-dimensional schematic diagram of the utility model;

[0013] In the figure: pipe body 1, axial rib plate 2, circumferential rib plate 3. DETAILED DESCRIPTION

[0014] The present invention will be further described below by way of examples with reference to the accompanying drawings.

[0015] See attached Figure 1 A vertically arranged dust removal duct comprises a duct body 1, axial ribs 2 and circumferential ribs 3. The duct body 1 is vertically arranged, and a plurality of circumferential ribs 3 arranged up and down are provided in the duct body 1. The plurality of circumferential ribs 3 are connected together by a plurality of axial ribs 2.

[0016] In this embodiment, refer to the attached Figure 1 The pipe body 1 is a pipe with a length of 1100 mm, a thickness of 10 mm, and a diameter of 1200 mm, arranged vertically, and the arrow indicates the direction of dust flow.

[0017] The circumferential rib plate 3 is in the shape of a ring, with an outer circumference of 3768 mm, a width of 80 mm, and a thickness of 10 mm. It is inclined upward and forms an angle of 60° with the pipeline body 1. A circumferential rib plate 3 is welded every 100 mm. This data stores solid particles to the greatest extent possible. The circumferential rib plate 3 protects the pipeline body 1 from impact and friction of solid particles, thereby extending the service life of the pipeline body.

[0018] The axial rib plate 2 is rectangular, 1100 mm long, 10 mm thick and 80 mm wide.

[0019] Working principle:

[0020] See attached Figure 1 The arrow indicates the dust flow direction. When solid particles flow from top to bottom at various angles, some solid particles accumulate between the circumferential rib plate 3 and the pipe body 1. The solid particles that fall again will impact the accumulated particles between the circumferential rib plate 3 and the pipe body 1, forming material hitting. The circumferential rib plate 3 forms an eaves protection for the pipe body 1, blocking the impact of solid particles, thereby extending the life of the pipe.
