Linear knife belt conveyor for material protection

Question

Accepted Answer

With the development of various industries and the development of the market, linear knife belt conveyors have gradually become the necessary transportation equipment for various industries. When the linear knife belt conveyor is used as the traction member and the conveying length is large, the conveying speed should not be too large to prevent the increase of the dynamic load. For linear knife belt conveyors that perform process operations at the same time, the conveying speed should be determined according to the requirements of the production process. In the process of transporting materials by a linear knife belt conveyor, the running time and efficiency determine the amount of coal transported by the linear knife belt conveyor. To this end, the running time should be increased as much as possible. Generally speaking, under the same load condition, the higher the operating rate of the equipment, the larger the conveying capacity. Therefore, in the machine work, all feasible and effective methods should be adopted to reduce the running time. For example, in the work, if the linear knife belt conveyor fails, the temporary maintenance method can be adopted to ensure the normal operation of the equipment and the repair and maintenance work is postponed to work if the guarantee range is not expanded and the front dam is not affected. After the end.

During the operation of the linear knife belt conveyor, the running time and efficiency determine the conveying capacity of the linear knife belt conveyor. To this end, the running time should be increased as much as possible. In general, the higher the operating rate of the equipment under the same load conditions, the greater the throughput. Therefore, in the work of the machine, it is necessary to adopt all feasible and effective methods to reduce its running time. For example, in the work, if the linear blade belt conveyor malfunctions, under the premise of ensuring that the fault range does not expand and does not affect the subsequent work, temporary maintenance can be adopted to ensure the normal operation of the equipment, and the repair and maintenance work is postponed until After the work is over.

In addition, during the operation of the linear knife belt conveyor, there may be curvature in the vertical and horizontal directions, but it must be controlled within the allowable range. If the elbow is too large or has a sharp bend, the chute will be damaged under the action of external force. Once the chute is lost or damaged, the joint will be out of control. At this time, the powder will leak into the trough, which not only increases the running resistance, but also A safety incident may result from a blockage. Linear knife belt conveyors can be used for horizontal transport or for inclined transport. When the linear knife belt conveyor is transported obliquely upward, the inclination angle of the coal seam shall not exceed 25°. When transporting downward, the inclination angle shall not exceed 20°. When the inclination angle of the coal seam is large, anti-skid devices shall be installed. The flexible linear knife belt conveyor allows bending in the horizontal and vertical directions of 2°-4°. In addition, linear knife belt conveyors can cause personal safety accidents if they are not laid flat.

Standard operation of linear knife belt conveyor to improve operational stability

In order to ensure the stability of the linear knife belt conveyor operation, it is necessary to standardize the operation, starting from the following aspects:

(1) Before starting the linear knife belt conveyor, it must be intermittently jogged, and after a few seconds, it will be officially started. The main purpose of this is to determine whether the linear knife belt conveyor can run normally, and at the same time, It should be used as a warning for people walking nearby; usually, the linear knife belt conveyor should be started first, then the coal should be loaded, and the load should not be forced to start; if it is started, if it does not start normally, you need to find out Reason, and do a good deal in time.

(2) During the start-up process, the starting direction should be started from the outside to the inside in the direction of the reverse flow; if the machine stops running, it cannot be packed.

(3) In the working surface, in order to avoid the linear knife belt conveyor can not be started due to full load, it is better to adopt the segmentation method and take effective measures; in order to avoid accidents, the linear knife belt conveyor runs stably and maintains the load. Reasonable operation of the conveyor

In the operation of the linear knife belt conveyor, in order to ensure the effective performance of its transport capacity, it is best to ensure that its load reaches the rated value. In the course of operation, if there is too little load, not only will it not be a work target, but the running ability will not be fully exerted; if there is too much load, the object will overflow the chute, which wastes labor and can cause damage to the machine. . In addition, in order to ensure the safe operation of the equipment, the service life of the linear knife belt conveyor is improved, and the uniformity of the load operation is also ensured.
