Embodiment
[0031] Such as Figure 1-Figure 7 The super-deep shaft concrete vertical conveying equipment with anti-wear and quick dredging structure includes several groups of conveying main pipes 1. After testing, the steel pipe with a diameter of 320mm is the most suitable in terms of cost, conveying smoothness, and installation convenience and safety. , the conveying main pipes 1 are flexibly connected by flanges and bolts, and the bottom end of the terminal conveying main pipe 1 is provided with a stilling converter 2, and the stilling converter 2 has lateral branches arranged obliquely, and the bottom of the stilling converter 2 The end is provided with a flange cover 3, and the space formed by the flange cover 3 and the stilling converter 2 is provided with a middle stone pile 9.
[0032] In other embodiments, the top of the middle stone pile 9 is inclined, and the degree of inclination of the middle stone pile 9 is consistent with the degree of inclination of the lateral branches o...

The invention discloses ultra-deep vertical shaft concrete vertical conveying equipment with a wear-resistant and rapid dredging structure. The ultra-deep vertical shaft concrete vertical conveying equipment comprises a plurality of groups of conveying main pipes, the conveying main pipes are movably connected through flanges and bolts, the bottom ends of the conveying main pipes are provided with stilling converters, and the stilling converters are provided with lateral branches which are obliquely arranged. According to the ultra-deep vertical shaft concrete vertical conveying equipment with the wear-resistant and rapid dredging structure, a herringbone stilling converter is adopted at the bottom end of a conveying pipeline to replace a corner steel pipe, middle stone piles are arranged at the corners of the stilling converter, so that the thickness of a pipe wall at the vertical stress position is increased, meanwhile, a buffering inclined face is formed, the impact force effect of material falling is resisted is achieved, and meanwhile material steering is facilitated; an Mn17 wear-resistant reinforcing plate, a flow deflecting sheet and a steel bar ring are combined to form a wear-resistant speed reduction system, so that the speed and the impact force of materials are reduced; and a detachable sealing flange cover is arranged so that the pipeline can be dredged conveniently, through the design, impact abrasion at the corners of the pipeline can be effectively reduced, and convenience is provided for rapid dredging of blockage materials.
Description
technical field [0001] The invention belongs to the technical field of shaft conveying equipment, and in particular relates to vertical concrete conveying equipment for ultra-deep shafts with an anti-wear fast dredging structure. Background technique [0002] Xin'an County Yinzhen Jijian Project is one of the key Yellow River diversion projects in Luoyang City. The development task is to divert water through underground tunnels to meet Xin'an County's domestic water supply and industrial water needs along the Jianhe River, improve the ecological environment of the Jianhe River, and ensure agricultural efficiency in irrigation areas. Farmers Increase income and give full play to the role of tributary storage capacity in the Xiaolangdi reservoir area. The grade of this project is Ⅲ, and the level of the main buildings is 3. The tunnel is a non-pressure tunnel, with a total length of about 13.601km, a gradient of 1 / 5038, and a designed maximum diversion flow of 2.2m 3 / s. Th...
