Due to the continuous increase in the use of mining materials, the corresponding mining scale is constantly increasing. During the production process, it is necessary to ensure the normal operation of the work. Therefore, the requirements for the stable operation of the sidewall belt conveyor are also very important. We will use the belt below. The more stable operation of the machine is explained in detail.
Belt conveyors are indispensable in mining: they have the advantages of large capacity, long transmission distance, continuous transportation, etc., and can be automated and remotely controlled. Therefore, conveyor equipment has a wide range of applications, but with the rapid level of technology automation The increase and the increase in the number of mining have a higher demand for operation requirements and efficiency. In the operation and production process, a large inclination and long-distance belt conveyor machine with higher operation intensity has been invested. The current large inclination can reach 50 degrees, but it is increasing. At the same time of large inclination, special attention must be paid to the operation stability of the equipment. In addition to the equipped brake equipment, a scientific and reasonable layout is also required to make the belt conveyor equipment operate more stably.
If the belt conveyor stops transporting a large amount of mineral materials, there will be materials attached to the skirt conveyor belt, and the sliding force will cause the whole machine to slide backward, which will cause abnormal accidents. To avoid such problems, reliable protection must be configured. Inverter, this can ensure the stable operation of the large-incline belt conveyor. The prerequisite for the selection is to measure the sliding moment of the conveyor at the time of working capacity. Within ten meters from the loading point to the front of the operation, the installation angle of the tailstock and the middle frame of this section is reduced to less than 30 degrees, so that the installation angle of the whole machine is smaller than the dynamic dumping angle of the raw materials, so that the materials are waiting to be loaded. After stabilizing on the rubber belt, enter the operating condition of large inclination.
In order to avoid the problem of belt slippage when the belt conveyor is in use, a high-strength flame-retardant pattern steel wire rope core tear-resistant conveyor belt can be selected to increase the frictional resistance between the belt surface and the belt body is laid flat in a deep groove shape. For the roller group, the upper groove angle of the misaligned roller can be selected to be 60 degrees to increase the lateral squeezing force between the material and the wire rope conveyor belt and prevent the whole machine from spattering during use. According to the sidewall belt conveyor The carrying capacity needs to be equipped with an appropriate loading mechanism, and then use the hopper to select an appropriate angle according to the site conditions. The chute is designed into a spoon shape, and the blanking direction is changed to horizontal. This can ensure smoother conveying and reduce the impact on the belt. .
In addition, choose a suitable frequency conversion soft start method, and set a closed protective device on the upper belt to prevent the material rolling due to excessive inclination. A closed scraper is placed in the middle of the lower belt to prevent the material from rolling towards the machine. These tails are very important to the smooth operation of the conveyor. Reasonable protection of the tail can prevent abnormalities such as misalignment of the belt caused by debris and stones, and damage to the broken belt. We can completely seal the tail.
Increase the storage capacity to reduce the frequent operation of the belt conveyor, avoid overloading operation, strictly control the moisture of the material, prevent the mixing of water in other production and transportation links, repair the belt pattern wear, after technical analysis and field observation, the large inclination belt conveyor Due to the frictional resistance between the material and the non-slip rubber conveyor belt when running at a constant speed, the rapid increase in the sliding speed will cause the pattern part of the industrial rubber belt to wear. If it is not repaired in time, the belt will not be able to convey the material. Therefore, professional rubber should be used. Repair in time such as cold sticking method;
