Guide: The belt conveyor is very familiar to everyone, but the design of the long-distance belt conveyor is not as simple as imagined. Usually, it is necessary to combine the terrain, drive, flip and tension and other major components, so as to ensure the normal operation of the equipment. The need for power distribution and maintenance. The belt conveyors are familiar to everyone, but the design of long-distance belt conveyors is not as simple as imagined. Usually, it is necessary to combine the terrain, drive, flip and tension and other major components, so as to ensure the normal operation of the equipment and the supply. The need for electricity and maintenance is the focus and difficulty of design work.
The process layout of the long-distance belt in the vertical mill production line mainly includes: overall layout, drive arrangement, turning device arrangement and tensioning device arrangement. The first is the overall layout of the long distance belt in the vertical mill production line. Due to the long conveying distance of long belts and the fact that the terrain is complex outside the production area, the process layout of the long belt directly affects the investment cost, the construction difficulty and the subsequent production operation and maintenance. The overall layout of the regional layout plan should be combined with the location of the long belt feeding point and the discharge point to select a relatively close and less undulating route. High-voltage lines, oil pipelines, dense residential areas, highways, etc. should be avoided in the layout area. The impact of railways, etc. Generally, it is impossible to take care of all the problems, so it is necessary to divide the long belt into two or a few sections. The height of the corridor can meet the requirements of clearance, try to avoid high brackets, arrange as far as possible along the terrain, reduce investment costs and operating costs. The belt conveyor corridor should be closed when it is close to the residential area to reduce the impact of belt conveyor noise on the sensitive area.
Followed by the drive arrangement of the long distance belt in the vertical mill production line. The drive of the long belt is very different from the ordinary belt. Ordinary belt drive devices generally use a single drive, low-voltage motor, head wheel as the drive roller, and the down belt conveyor can use the tail wheel as the drive roller. The long belt drive is generally double-drive or multi-drive, and most of them are high-voltage motors. Considering the layout space and convenient maintenance, the drive device can be placed on the ground below the belt conveyor, close to the head or tail of the belt conveyor, facilitating adjacent belts. The machine is centrally powered, and the head and tail wheels are only used as reversing rollers.
Then there is the turning device arrangement of the long distance belt in the vertical mill production line. The turning device of the belt conveyor reverses the conveyor belt that has bypassed the head drum with its working surface facing up without contacting the lower idler. Before turning around the tail roller, it can be turned over and reset to avoid the scraping of the residue on the conveyor belt to the ground when the lower roller is in contact with the working surface of the conveyor belt. Generally used on long belts, the longer the conveying distance, the more significant the economic benefits. In the long belt arrangement, it is necessary to consider the arrangement space of each set of turning devices in the head and tail of the long belt, and each turning device needs about 30m~40m and is to be closed.
In addition, the tensioning device is arranged for the long distance belt in the vertical mill production line. The function of the tensioning device is to tension the conveyor belt to provide the working tension required to ensure normal operation, while also compensating for the elastic elongation of the conveyor belt. The tensioning device of the long-distance belt conveyor mainly depends on the force exerted by the belt running direction and the arrangement space of the surrounding space. The position of the tensioning device in the long belt is generally close to the driving roller, so that the reaction time is shorter and the tensioning effect is better.
The design of long-distance belts in vertical mill production lines is a complex project involving many aspects. In addition, since the long belt is generally a mixed arrangement belt in which the up section, the down section, and the horizontal section are combined, it is necessary to consider the section when calculating the power and the force.
