[0002] During the dust removal operation, dust removal ducts are generally required to transport the dust. The dust usually contains particulate materials, which will cause collision and friction on the dust removal duct during high-speed flow, which can easily cause local wear of the dust removal duct, resulting in thinning, perforation or even damage to the duct wall, causing problems such as air leakage and material leakage.

[0003] In order to solve the above problems, people usually make the wall of the dust removal duct thicker to enhance its wear resistance; or use physical methods to replace the dust removal duct with a material with better wear resistance to reduce the collision friction of the material dust particles and increase the wear resistance.

[0004] However, in the related dust removal duct loss reduction technology, increasing the thickness of the duct wall and replacing the material to improve the wear resistance of the duct will significantly increase the cost. Utility Model Content

[0035] In order to facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0036] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be an intermediate element. The terms "mounted", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this document pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] The following combination Figures 1 to 5 It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute any limitation to the present invention.

[0039] Combine Figures 1 to 5 An embodiment of the present invention provides a wear reducing device for a dust removal air duct, which includes a support plate 100 and a plate member 200.

[0040] The first surface 110 of the support plate 100 is fixed on the windward side of the dust removal duct.

[0041] There are multiple panels 200 , all of which are arranged on the second surface 120 of the support plate 100 . The area formed by the multiple panels 200 is larger than the coverage area of the windward surface.

[0042] When the airflow enters the dust removal duct, it will first come into contact with the multiple plates 200 located on the windward side, and the dust particles in the airflow will also first collide with the multiple plates 200. The kinetic energy of the dust particles will be weakened and then hit other positions of the dust removal duct to reduce collision and wear on the dust removal duct.

[0043] It can be understood that the wear-reducing device for the dust-collecting air duct provided by the embodiment of the present invention, by arranging multiple plates 200 at the windward position in the dust-collecting air duct, the area formed by the multiple plates 200 is larger than the area covered by the windward position of the dust-collecting air duct, so that the dust particles in the air flow entering the dust-collecting air duct first collide with the multiple plates 200 located at the windward position, and the kinetic energy of the dust particles is weakened before colliding with other positions of the dust-collecting air duct, which can reduce the wear of the dust particles on the dust-collecting air duct, thereby improving the wear resistance of the dust-collecting air duct; in addition, since the wear-reducing device is arranged at the windward position of the dust-collecting air duct instead of thickening the entire dust-collecting air duct, the cost is greatly reduced, and there is no need to replace the dust-collecting air duct with a material with better wear resistance, which can also achieve the effect of improving the wear resistance of the dust-collecting air duct while reducing its manufacturing cost.

[0044] Specifically, in some embodiments of the present invention, the first surface 110 of the support plate 100 matches the shape of the windward surface of the dust removal duct, allowing the support plate 100 to fit tightly within the dust removal duct, preventing the support plate 100 from falling due to collisions with high-speed airflow and dust particles, and improving the stability of the wear reduction device. For example, if the windward surface of the dust removal duct is curved, the curvature of the first surface 110 of the support plate 100 is the same as the curvature of the windward surface of the dust removal duct.

[0045] To block more dust particles, minimize their collisions with other locations in the dust removal duct, and minimize the increase in airflow resistance, in some embodiments of the present invention, the gaps between each plate 200 are uniform and evenly distributed, and the length of the plate 200 aligns with the direction of the airflow entering the dust removal duct. Dust particles are partially embedded in the gaps, allowing them to offset collisions with dust particles, rather than requiring other locations in the dust removal duct to directly react to collisions. This significantly reduces kinetic energy and reduces wear.

[0046] Of course, in order to more effectively reduce the kinetic energy of dust particles, in some embodiments of the present invention, the gaps between the plates 200 can be 0.5 mm to 2 mm, making the gaps between the multiple plates 200 closer. For example, the gaps between the plates 200 are set to 1 mm.

[0047] Furthermore, in some embodiments of the present invention, the heights from the top of each plate 200 to the second surface 120 of the support plate 100 are the same, so as to avoid causing resistance to the airflow and affecting the passage of the airflow.

[0048] Of course, the height between the top of each plate 200 and the second surface 120 of the support plate 100 can be 20 mm to 30 mm, significantly improving the wear resistance of the dust removal duct. For example, if the height between the top of each plate 200 and the second surface 120 of the support plate 100 is 25 mm, and the wall thickness at other locations of the dust removal duct is 2.5 mm, the local wear resistance of the windward side of the dust removal duct is improved tenfold.

[0049] In order to facilitate the installation of the wear reduction device and further reduce manufacturing costs, in some embodiments of the present invention, the plate 200 is fixed to the second surface 120 of the support plate 100 by welding, and the support plate 100 is fixed to the windward surface of the dust removal duct by welding.

[0050] Of course, the plate 200 in the wear reduction device for the dust removal air duct provided in the embodiment of the present invention can be a strip of flat steel, which is convenient to manufacture and simplifies the manufacturing process.

[0051] An embodiment of the present invention further provides a dust removal air duct, which includes the above-mentioned wear reduction device for the dust removal air duct and a dust removal air duct body 300.

[0052] The wear reducing device is arranged on the windward side of the dust removal duct body 300 .

[0053] It is understandable that the dust removal duct provided by the embodiment of the present invention, since it includes the above-mentioned wear reduction device, must have all the advantages of the device. That is, the dust removal duct is provided with multiple plates 200 at the windward position of the dust removal duct, and the area formed by the multiple plates 200 is larger than the area covered by the windward position of the dust removal duct, so that the dust particles in the air flow entering the dust removal duct first collide with the multiple plates 200 located at the windward position, and the kinetic energy of the dust particles is weakened before colliding with other positions of the dust removal duct, which can reduce the wear of the dust particles on the dust removal duct, thereby improving the wear resistance of the dust removal duct; In addition, since the wear reduction device is provided at the windward position of the dust removal duct, rather than thickening the entire dust removal duct, the cost is greatly reduced, and there is no need to replace the dust removal duct with a material with better wear resistance, which can also achieve the effect of improving the wear resistance of the dust removal duct while reducing its manufacturing cost.

[0054] In some embodiments of the present invention, the dust removal air duct is provided with a first air inlet 310 and a second air inlet 320 .

[0055] The first air inlet 310 and the second air inlet 320 extend in directions that intersect with each other.

[0056] The wear reducing device is arranged in the dust removal air duct body 300 and is located on the windward side facing the intersection. The dust removal air duct with multiple air inlets can also use the wear reducing device to improve wear resistance.
