Application of guide groove in belt conveyor

The data required for the design of transfer chute varies with different applications, and the design information required in practice usually includes: Information of processed materials, such as lumpiness, fine particle distribution, humidity, material density, accumulation Angle, adhesion characteristics, etc. (It is recommended to refer to several engineering examples obtained from practice, including humidity difference, the comparison between large materials and fine particles, etc., and the accuracy of design calculation has been confirmed by the measurement of material flow characteristics); The speed of the conveyor belt and two acid and alkali resistant conveyor belts needed, the running direction of the industrial conveyor belt, the vertical distance and horizontal deviation of the two rubber conveyor belts, the transmission distance, the data of the conveyor belt, the roller and the roller; Determine the buffer method used, such as short distance buffer conveyor, material box or suitable buffer structure, choose chute liner material, after installation should be easy to replace, carefully consider the existence of pipeline, electrical pipeline, adjacent structure, dust collection, in place to facilitate the installation and lifting chute components, tube funnel and chute components have serialized spectrum, However, with the different engineering applications, only the traditional continuous model design calculation method can not meet the actual needs. The height of the groove, the height of the guide groove must be enough to accommodate the amount of material loaded on the conveyor belt; The gap between the guide groove and the rubber conveyor belt, the distance between the metal (or wooden) bottom edge of the guide groove and the working surface of the industrial conveyor belt shall not be less than 25mm, and the gap should be increased evenly along the direction of the conveyor belt. As mentioned above, the uniformly increased gap can make the block material or foreign material move forward without getting stuck between the bottom edge of the guide groove and the conveyor belt. Larger clearance can be used, but the width and thickness of the rubber side plate need to be increased, especially for the long guide groove should be so; Guide groove rubber side plate, in order to prevent powder from leaking out from the bottom side of guide groove and running conveyor belt, the usual practice is to install 10-12mm thick long strip of hard rubber plate on the outside of guide groove, these rubber plates are fixed or clamped on the guide groove side baffle with bolts, so that in the initial installation or after wear, The rubber plate can be adjusted to make it gently against the heat resistant conveyor belt working surface, the side plate should be made of hard rubber, its hardness is at least 60 to 100 hardness tester units, in order not to clamp wear particles make circular conveyor belt covered by rubber wear, rubber side plate should not be with fiber fabric, the old rubber belt can not be used as a guide groove side plate, The width of the rubber side plate depends on its fixing method and allowable wear on the guide groove. The rubber side plate can be installed vertically or at a certain Angle. Because the bearing polyester conveyor belt will bend between two idlers, the rubber side plate installed at a certain Angle can play a better sealing role, but it must be carefully designed. In order to achieve a good sealing effect under the condition that the rubber covering wear of the conveyor belt is minimal, if the material characteristics, such as uniform material particle size, greater than 25mm, no powder, etc. allow, the guide trough can not use the rubber side plate, but only under the condition that the guide trough side baffle and the edge of the canvas conveyor belt are not very close to each other. Guide groove without rubber side plate can reduce the ordinary conveyor belt covering rubber wear and scratch; When the guide groove is opened outwards, the scope of the rubber side plate pressing on the flame retardant conveyor belt is relatively large, which can reduce the possibility that the cover of the transport belt is ground out of the ditch. The rubber side plate of the guide groove should be adjusted frequently to make it just contact the surface of the heavy conveyor belt, and the side plate can be pressed on the transport belt.
