Description

Technical Field

[0001] The utility model relates to the technical field of gangue screening equipment of a filling system, in particular to a gangue screening and transportation integrated belt conveyor. Background Art

[0002] The traditional filling system gangue screening and conveying belt conveyor consists of two belt conveyors, one responsible for unloading the gangue raw materials and the other for transporting the screened gangue, and the two parts operate independently. When filling the mine, the gangue and other materials are first transported to the screener through the unloading drum for screening. The screened granular materials fall onto the belt conveyor with the tail drum, and then the materials are separated. Figure 2 As shown, the belt conveyor responsible for unloading the gangue raw materials and the belt conveyor for transporting the screened gangue are arranged up and down with a height difference, with a gap between them, no connection relationship, and they operate independently.

[0003] In the installation of traditional conveyor belt conveyors, two sets of independent drive equipment are required to drive the unloading drum and the tail drum respectively. The high operating cost of the internal drive mechanism and the need for regular maintenance and servicing make its production cost relatively high. Since the unloading drum and the tail drum operate independently, their operating speeds need to be adjusted manually to keep consistent, which is not very flexible. If the speed of the tail drum is too low, the screened materials will accumulate and the material distribution will be uneven, resulting in excessive local load on the belt conveyor, which will affect the service life of the belt conveyor. If the speed of the tail drum is too fast, the space of the tail drum cannot be fully utilized, resulting in low working efficiency. Since there is a gap between them, the gangue is easy to fall from the gap during screening. Utility Model Content

[0004] The purpose of the utility model is to propose and design an integrated belt conveyor for gangue screening and transportation, in view of the high installation cost, low flexibility, uneven operating speed and material distribution problems existing in the traditional filling system gangue screening and transportation belt conveyor which is driven by two sets of independent driving devices to drive the unloading roller and the tail roller respectively, so as to realize the coarse and fine separation of gangue and the continuous supply of gangue at low cost and high efficiency.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a gangue screening and transporting integrated belt conveyor, including an unloading drum and a tail drum, the unloading drum is higher than the tail drum, the tail drum is located in front of the unloading drum in the conveying direction, a guide drum is arranged between the unloading drum and the tail drum, the unloading drum and the tail drum share the same belt, and the belt bypasses the guide drum. The unloading drum and the tail drum share the same belt, and the guide drum guides the belt, so that the belt between the unloading drum and the tail drum is smoothly transported in the correct conveying direction, and only one set of driving equipment is needed to drive the operation of the gangue screening and transporting belt conveyor, thereby saving its installation cost. At the same time, compared with the traditional gangue screening and transporting belt conveyor, since the improved belt conveyor realizes the integration of screening and transport, the transport speed of the unloading drum and the tail drum is consistent, which ensures the continuous and uniform screening and transport of materials and improves its work efficiency. In addition, the belt blocks the gap between the unloading drum and the tail drum, blocks the gangue falling from the unloading drum, and does not fall out of the gap.

[0006] Further, the guide roller comprises a lower guide roller, and the belt between the lower guide roller and the tail roller is horizontal, so as to ensure the horizontal conveyance of this section, that is, the horizontal conveyance of the gangue dropped from the unloading roller.

[0007] Furthermore, the lower guide roller is higher than the tail roller, and the belt passes around the lower guide roller from the rear and is connected to the tail roller, so as to achieve guidance, so that the belt between the lower guide roller and the tail roller is horizontal, and the lower guide roller can tighten the belt, so that the belt runs more stably.

[0008] Furthermore, the guide roller also includes an upper guide roller, which is higher than the lower guide roller, and lower than the unloading roller, and both the upper guide roller and the lower guide roller are located behind the unloading roller. By arranging the upper guide roller and the lower guide roller backward, the belt between the unloading roller and the tail roller is tightened, which has a better guiding and tightening effect, and is more conducive to ensuring a more stable operation of the belt.

[0009] Furthermore, the upper guide roller is located directly above the lower guide roller, the belt bypasses the unloading roller from the front and bypasses the upper guide roller and the lower guide roller from the rear to be connected to the tail roller, and the belt bypasses the tail roller from the front.

[0010] Furthermore, the belt between the unloading roller and the upper guide roller is arranged horizontally, the belt between the upper guide roller and the lower guide roller is arranged vertically, and the belt between the lower guide roller and the tail roller is arranged horizontally. A better layout ensures that the belt is tightened and the gangue is transported horizontally.

[0011] Furthermore, the upper guide roller and the lower guide roller are of the same size and are both unpowered rollers. There is no need to install a power device specifically for the guide roller, and the guide roller only provides guidance, saving installation costs. The upper guide roller and the lower guide roller are of the same size, which is convenient for finding a point for installation in the same vertical direction, and the same model is used when replacing, which is convenient for replacement.

[0012] Furthermore, a grading screen is arranged between the unloading drum and the tail drum. The grading screen is located below the unloading drum and above the tail drum. The grading screen can screen the gangue falling from the unloading drum. When the gangue on the unloading drum belt is screened by the grading screen, the fine gangue with small particles falls to the tail drum to realize material separation.

[0013] Further, the grading screen is located in front of the upper guide roller and the lower guide roller. The belt between the unloading roller and the tail roller is located behind the grading screen to block it.

[0014] It can be seen from the above technical solutions that the utility model has the following advantages:

[0015] This solution provides an integrated belt conveyor for gangue screening and transportation, which solves the problems of high installation and operation costs, low flexibility, uneven operating speeds and uneven material distribution, thereby realizing coarse and fine separation and continuous supply of gangue at low cost and high efficiency, and improving filling efficiency.
