Chain Scraper Conveyor and Scraper Chain Conveyor are commonly used in material conveying equipment, widely used in mining, metallurgy, building materials and other industries. Their working principles are similar, but there are differences in structure and application. The following is a detailed introduction to these two conveyors, including the working principle, precautions and operational safety.
I. Chain scraper conveyor
1. Working principle
The main working principle of chain scraper conveyor is as follows:
Structure composition: the conveyor is mainly composed of frame, chain, scraper, pallet, motor and tensioning device.
Conveying process:
Starting: the electric motor drives the chain movement.
Material shoveling up: the scraper attached to the chain moves forward driven by the chain, the scraper at the front end will shovel up the material and push the material forward.
Material conveying: the material is pushed to other parts of the conveyor by the scraper until the discharge port of the conveyor.
Material unloading: the material is slid backward along the Chain Scraper Conveyor by gravity during the movement of the chain to complete the conveying.
The conveyor is suitable for horizontal or mildly inclined conveying materials.
Scraper chain conveyor
1. Working principle
Scraper Chain Conveyor is a specific realization of chain scraper conveyor, its working principle is similar to that of chain scraper conveyor, but may have different design details:
Structural components: including chain, scraper, frame, drive device, etc..
Conveying process:
Starting: the electric motor drives the chain movement.
Material shoveling: scraper moves along the chain, shoveling and pushing the material located in the conveyor.
Material passes through the change chute: while the chain of the Scraper Chain Conveyor maintains its movement, the scraper will push the material to the discharge opening.
Discharge: The material is unloaded in the descending section of the chain by gravity or by the action of the scrapers.
Scraper Chain Conveyor is suitable for conveying all kinds of loose materials, especially when dealing with materials with poor fluidity.
Note
Material Characteristics: Understand the characteristics of the material to be conveyed in order to choose the suitable scraper material and design.
Load limitation: In normal operation, pay attention not to exceed the rated load of the equipment.
Chain wear: Regularly check the wear condition of chain and scraper, and replace the damaged parts in time.
Lubrication and maintenance: Regularly lubricate the chain and bearings to reduce friction and wear.
Environmental adaptability: When working in high temperature, high humidity, acid and alkali and other harsh environments, it is necessary to ensure that the performance of the equipment meets the requirements and take appropriate protective measures.
Fourth, operation safety
Training and qualification: The operator must receive special training and hold the corresponding operation qualification certificate, and be familiar with the working principle and operation regulations of the equipment.
Safety inspection: Before each operation, the operating status of the equipment should be checked, including the condition of the electrical system, mechanical connection and scraper and chain, to ensure that there is no abnormality.
Wearing protective equipment: Safety helmets, protective glasses, gloves and non-slip shoes should be worn during operation to avoid possible accidental injuries during operation.
Warning signs: Set up warning signs during equipment operation and maintenance to ensure that unrelated personnel stay away from the operation area.
Emergency Measures: Familiarize yourself with the location of the equipment emergency stop device and understand the emergency procedures in case of a malfunction or accident.
Cleaning and Maintenance: When cleaning and maintaining equipment, be sure to disconnect the power supply and ensure that the equipment is in a shutdown state.
Summary
Chain Scraper Conveyor and Scraper Chain Conveyor play an important role in industrial production, and their design and working principle, although similar, can be selected according to specific applications. Following safety norms and precautions in operation and maintenance can effectively improve the working efficiency of the equipment and reduce safety risks. Regular inspection and maintenance can ensure the long-term stable operation of the equipment and improve the efficiency of material transportation.
