The design points of sand conveyor belts involve multiple aspects to ensure their efficient, safe, and stable operation. Here are some key design points:
Working environment and conditions:
Consider how long the conveyor belt runs every day, how frequently it operates, and how it is fed and unloaded.
Evaluate the service life of the conveyor and consider how to extend its service life.
Conveyor line and conveyor belt:
Determine the inclination angle, length, lifting height, as well as the dimensions and connection dimensions of straight and curved sections of the conveyor line.
Choose appropriate conveyor belt materials, considering their verticality requirements, friction resistance coefficient, friction coefficient, and safety factor.
For long-distance transportation, special attention should be paid to the design of the conveyor belt's flipping, pipe formation, and unfolding to meet the principle of gradual progress.
Material properties:
Consider the characteristics of sand such as wear resistance, adhesion, friction coefficient, particle size, loose density, and angle of repose.
Determine the maximum cross-sectional area and available width of the material on the conveyor belt based on its properties.
Conveying capacity:
Determine whether the conveying capacity of the conveyor belt meets the demand based on the expected output.
Consider whether the material flow is uniform and whether the expected conveying effect can be achieved.
Structure and Design:
Design a reasonable support frame to secure the conveyor belt and ensure its stability.
Select appropriate transmission devices, such as motors and reducers, to drive the movement of the conveyor belt.
Consider installing cleaners on the conveyor belt, such as head cleaners and empty section cleaners, to remove materials and debris adhered to the conveyor belt.
In long-distance transportation, necessary facilities such as transfer stations, drive stations, and substations are set up to facilitate installation, transportation, and daily maintenance.
Safety and protection measures:
Design protective devices to prevent deviation, such as a self-aligning tube group, a reasonable arrangement of forward leaning side rollers, and an automatic deviation adjustment device.
Set up a belt speed detection and protection device to monitor the running speed of the conveyor belt and prevent abnormal situations.
Configure belt breakage protection devices, such as wedge catchers and roller catchers, to prevent the conveyor belt from slipping down after breaking.
Install metal debris detection and removal devices to ensure that there are no metal debris on the conveyor belt.
Energy conservation and environmental protection:
Choose a reasonable and energy-saving driving device, such as a controllable start/stop transmission device, to reduce energy consumption.
Design a sealed conveying system to avoid exposed material transportation and reduce dust and noise pollution.
In summary, the design points of sand conveyor belts cover multiple aspects such as working environment, conveying route, material properties, conveying capacity, structure and design, safety and protection measures, as well as energy conservation and environmental protection. These design points are interrelated and influence each other, together forming the complete framework of sand conveyor belt design.
砂子输送带的设计要点涉及多个方面，以确保其高效、安全、稳定地运行。以下是一些关键的设计要点：
-
工作环境与条件：
- 考虑输送带每天要运行多长时间，工作频率如何，以及如何进行给料和卸料。
- 评估输送机的使用寿命，并考虑如何延长其使用寿命。
-
输送线路与输送带：
- 确定输送线路的倾角、长度、提升高度，以及直线段和曲线段的尺寸、连接尺寸等。
- 选择合适的输送带材料，考虑其垂直度要求、摩擦阻力系数、摩擦系数以及安全系数等。
- 对于长距离输送，还需特别注意输送带的翻转、成管与展开等设计，以满足渐进原则。
-
物料性质：
- 考虑砂子的磨损性、粘结性、摩擦系数、粒度、松散密度以及安息角等特性。
- 根据物料的性质，确定输送带上最大的物料横截面积和可用宽度。
-
输送能力：
- 根据预期产量，确定输送带的输送能力是否满足需求。
- 考虑料流是否均匀，以及是否能够达到预期的输送效果。
-
结构与设计：
- 设计合理的支撑架，用于固定输送带，确保其稳定性。
- 选用合适的传动装置，如电机和减速器，以驱动输送带的运动。
- 考虑在输送带上设置清扫器，如头部清扫器和空段清扫器，以清除粘附在输送带上的物料和杂物。
- 在长距离输送中，设置转运站、驱动站房和变电站等必要设施，以方便安装运输和日常维护。
-
安全与保护措施：
- 设计防止跑偏的保护装置，如调心托管组、合理布置前倾的侧托辊以及跑偏自动调整装置。
- 设置带速检测保护装置，以监测输送带的运行速度并防止异常情况。
- 配置断带保护装置，如楔形捕捉器和滚轮捕捉器，以防止输送带断裂后下滑。
- 增设金属杂物检测与清除装置，以确保输送带上不含有金属杂物。
-
节能与环保：
- 选择合理节能的驱动装置，如可控启/停传动装置，以减少能耗。
- 设计密封的输送系统，避免物料裸露输送，减少粉尘和噪声污染。
综上所述，砂子输送带的设计要点涵盖了工作环境、输送线路、物料性质、输送能力、结构与设计、安全与保护措施以及节能与环保等多个方面。这些设计要点相互关联、相互影响，共同构成了砂子输送带设计的完整框架。
