Conveyor belt cleaning device:
Select suitable cleaning devices, such as scraper type cleaners, roller type cleaners, brush type cleaners, etc., to remove adhesive substances on the surface of the conveyor belt.
According to the actual situation, water jets and wiper cleaning devices can also be selected for auxiliary cleaning.
Conveyor belt flipping:
The flipping of the conveyor belt is the fundamental measure to prevent blockage of the lower space of the conveyor belt and material adhesion to the roller group.
The flipping methods mainly include free flipping, forced flipping, directional flipping, and tubular flipping. The appropriate flipping method is selected according to the bandwidth and strength of the conveyor belt.
Mechanical and electrical protection device:
Select necessary electromechanical protection devices, such as anti deviation protection device, belt speed detection protection device, belt breakage protection device, metal debris detection and removal device, and longitudinal tear protection device.
These protective devices can ensure timely shutdown of the conveyor belt in case of malfunction, protecting the equipment from further damage.
Flat turning design:
For long-distance belt conveyors, flat turns are essential.
When designing, the curvature radius of the turning section, turning measures, and corresponding parameters of the roller group should be considered to ensure that the conveyor belt can run smoothly during turning.
Drive device selection:
The driving device should have good starting, controllability, and overload protection capabilities.
Choose energy-saving driving devices to reduce energy consumption and operating costs.
For long-distance belt conveyors, it is also possible to consider using a multi motor drive method to evenly distribute the load of each motor.
Other considerations:
Most conveyor systems adopt the form of steel structure overhead piers, and their overhead height should meet the national limit requirements.
Belt conveyors should be sealed with colored steel plates throughout the entire process to avoid material exposure and reduce dust and noise pollution.
The transportation system should be equipped with facilities such as transfer stations, drive stations, and substations to facilitate installation, transportation, and daily maintenance.
In summary, the design of mining conveyor belts involves multiple aspects and requires comprehensive consideration of equipment reliability, engineering cost, terrain conditions, installation and maintenance convenience, and other factors. By optimizing the design, it is possible to ensure the stable operation of the conveyor belt in the mining environment, improve production efficiency, and reduce operating costs.
矿山输送带，特别是长距离带式输送机，因其特殊的工作环境和需求，在设计时需要综合考虑多个要点。以下是对矿山输送带设计要点的详细归纳：
一、设计原则
- 提高设备可靠性：确保输送带在各种工况下都能稳定运行，减少故障率。
- 降低工程造价：在保证性能的前提下，优化设计以降低材料、安装和运行成本。
- 考虑地形条件：根据矿山的实际地形进行布局设计，避开复杂地形和障碍物。
- 便于安装与维护：设计时要考虑输送带的安装便捷性和日常维护保养的可操作性。
二、具体设计要点
-
缓冲受料装置：
- 带式输送机在受料点承受较大的冲击，因此需要采用合理的缓冲装置来减小对胶带的冲击。
- 可以选用带托板的整体式缓冲受料装置，集合缓冲托辊和缓冲床的优点，有效降低落料高差对胶带的冲击。
-
管状皮带设计：
- 对于管状皮带，其成管与展开必须满足渐进原则，确保输送带在过渡段能够平稳变形。
- 过渡段的长度应合理设计，避免产生过大的附加变形和应力。
-
输送带清扫装置：
- 选用适宜的清扫装置，如刮板式清扫器、辊式清扫装置、刷式清扫装置等，以清除输送带表面的粘附物。
- 根据实际情况，还可以选择喷水器和刮水器清扫装置进行辅助清扫。
-
输送带翻转：
- 输送带的翻转是防止堵塞输送带下部空间和物料黏附于托辊组的根本措施。
- 翻转方法主要有自由翻转、强制翻转、定向翻转和管形翻转等，根据输送带的带宽和强度选择合适的翻转方式。
-
机电保护装置：
- 选用必需的机电保护装置，如防止跑偏保护装置、带速检测保护装置、断带保护装置、金属杂物检测与清除装置以及纵向撕裂保护装置等。
- 这些保护装置能够确保输送带在发生故障时及时停机，保护设备免受进一步损坏。
-
平面转弯设计：
- 对于长距离带式输送机，平面转弯是必不可少的。
- 设计时要考虑转弯段的曲率半径、转弯措施以及相应的托辊组参数等，确保输送带在转弯时能够平稳运行。
-
驱动装置选择：
- 驱动装置应具有良好的启动性、可控性和过载保护能力。
- 选用节能型驱动装置，降低能耗和运行成本。
- 对于长距离带式输送机，还可以考虑采用多电机驱动方式，使各电机的负载均匀分布。
-
其他考虑因素：
- 输送机系统大部分采用钢结构架空栈桥形式，其架空高度应满足国家规定的限界要求。
- 带式输送机全程应设彩钢板密封，避免物料无裸露输送，减少粉尘和噪声污染。
- 输送系统中应设有转运站、驱动站房和变电站等设施，方便安装运输和日常维护。
综上所述，矿山输送带的设计要点涉及多个方面，需要综合考虑设备可靠性、工程造价、地形条件、安装与维护便捷性等多个因素。通过优化设计，可以确保输送带在矿山环境中稳定运行，提高生产效率并降低运行成本。
