I. Types of Scraper Conveyor
There are various types of Scraper Conveyor, mainly depending on the usage scenario, industry needs and the way the manufacturer categorizes them. The following are some common types of Scraper Conveyor:
TGW type scraper conveyor: usually used for horizontal or slightly inclined material conveying, suitable for mining, metallurgy, construction and many other industries.
MS type scraper conveyor: a common conveying equipment, suitable for large-scale material conveying, commonly used in coal mines, power plants and other occasions.
GB type scraper conveyor: commonly used in coal mines, ports and other fields, can be customized according to the need, suitable for different material conveying requirements.
TYS type scraper conveyor: commonly used in construction sites, port terminals and other places, suitable for various types of material conveying.
ZB type scraper conveyor: usually used in mining, coal mine and other environments, suitable for conveying large materials or granular materials.
MSH type scraper conveyor: suitable for conveying coal, ore and other materials, commonly used in mines and industrial and mining enterprises.
MC type scraper conveyor: commonly used in mining, metallurgy, building materials and other industries, suitable for various types of material conveying.
TCS type scraper conveyor: suitable for large-scale material conveying, commonly used in mining, power plant, harbor and other industries.
Please note that the above list is only part of the common Scraper Conveyor model, the actual market there are more kinds of Scraper Conveyor.
Second, the working principle of the Scraper Conveyor
The working principle of Scraper Conveyor is relatively simple and efficient. Specifically, its working principle is as follows:
The open chute as a coal, gangue or material, etc. bearing pieces.
The scraper is fixed on the chain (composed of scraper chain) as the traction member.
When the head drive department starts, it drives the sprocket on the head shaft to rotate, so that the scraper chain circulates.
The scraper chain drives the material along the chute until it reaches the head for unloading.
The scraper chain runs around the sprocket wheel for stepless closed cycle, so as to complete the continuous conveying of materials.
C. Precautions for the use of Scraper Conveyor
In order to ensure the safe and efficient operation of the Scraper Conveyor, the use of the following matters need attention:
Installation quality: the installation quality of Scraper Conveyor must meet the specified requirements, and the pressure and bump column must be firm and reliable.
Safety facilities: the head of each Scraper Conveyor should be equipped with a protective cover or protective railing to prevent personnel from accidentally touching or being injured. The tail of the first Scraper Conveyor of Shunto which is close to the working face must be covered to prevent personnel from being hurt by accidentally entering the tail of the machine.
The order of picking and placing: the order of picking and placing of the materials transported by the Scraper Conveyor should be reasonable; when placing the materials, it should follow the running direction of the scraper and put the front end first and then the tail end; when picking up the materials, it should pick up the tail end first and then the front end, so as to prevent the materials from supporting the scraper and hurting the personnel.
Prohibit crossing: It is prohibited to cross the conveyor at the head and tail of the machine to prevent accidents.
Troubleshooting: When the underground electrician handles the fault of Scraper Conveyor, he must stop the power to make the Scraper Conveyor stop running, and hang the sign of "under maintenance, no power supply" to prevent others from misoperation which may cause accidents.
Signal warning: In the whole length of the Scraper Conveyor, sound and light signals or alarms should be installed, and a signal should be sent out before starting the machine, and then a test drive should be carried out to confirm that there is no problem before starting the machine.
In summary, Scraper Conveyor as an important material handling equipment, has a wide range of applications in a variety of industries. Understanding its type, working principle and the use of precautions, to ensure the normal operation of the equipment and personnel safety is of great significance.
