Belt conveyor covers is made of cold-rolled hot-dip galvanized color coated board. The plate base is an excellent cold-rolled steel plate. Two layers are hot aluminum zinc layer, three layers are chemical conversion layer, four layers are initial coating layer, and five layers are fine coating layer. PE film selection of domestic excellent bonbon paint, good adhesion, a wide range of formability and outdoor sex, excellent chemical resistance, service life of 10 years. belt conveyor covers fixed, open and with observation window, you can see the material in the transmission process and the conveyor belt operation is normal, there is a deviation cover, for the conveyor with deviation switch to play the role of rain, dust and so on. Color steel belt conveyor covers different colors, sea blue, white gray, red and so on to meet customer needs, can also be customized color, shape.
Belt conveyor covers how to do the strength is better, color steel plate to cold rolled steel plate as the base material, the degreasing, phosphating and chromic salt treatment, under the protection of nitrogen for double-sided hot dip galvanizing, and then easy to primer solid adhesion of the chemical conversion film, and then coated with epoxy resin primer, but also coated with chemical corrosion resistance of color finish paint. At present, color steel plate has developed a number of varieties, there are single layer color steel plate, sandwich color steel plate, sandwich color steel plate and polystyrene and rock wool color steel plate. With the further expansion of the use of color steel plate, the user's requirements for color steel plate are also constantly improving.
Below, for you to introduce the characteristics of the belt conveyor covers built-in pressure belt device:
The device comprises a press wheel support fixed on the middle support; The shape of the pressure wheel bracket is a gantry structure, the cross beam of the pressure wheel bracket is arranged for the axial vertical conveyor conveying direction of the pressure belt pressure, the pressure wheel bracket is lower than the preset height of the belt conveyor covers, And its larger width is lower than the preset width of belt conveyor covers; The press wheel is two and symmetrical against the belt surface on both sides of the upper belt along the middle line of the upper belt; The pressure wheel support comprises two support parts which are directly and fixedly connected with the two sides of the middle support and the two ends of the arc bracket are respectively set up on the two support parts. The support part and the arc bracket part are fixedly connected to form the curved gantry structure of the pressure wheel support; A waist-shaped hole is arranged in the longitudinal plumb line on each support part, and a mounting hole is arranged at the corresponding matching end of the curved support part, and the bolts are fixedly connected between the two. There are multiple waist holes and mounting holes, and the corresponding holes are arranged in the corresponding support part and the arc support part and are distributed in turn along the vertical direction of the lead.
The device also includes a support hanging ear used to fix the pressure wheel on the pressure wheel support. The support hanging ear is arranged at both ends of each pressure wheel shaft and forms a rolling fit with each wheel shaft end of the pressure wheel. The support hanging ear can adjust the reciprocating displacement along the pressure wheel support in the conveying direction perpendicular to the conveyor. A waist shaped mounting hole is provided at the end of the support bracket for matching the pressure wheel, and the length direction of the waist shaped mounting hole is perpendicular to the conveying direction of the conveyor. A bolt hole is provided on the pressure wheel bracket for the waist shaped mounting hole, and the two forms a bolt fixing fit. The device also includes a vertical roll support arranged at both sides of the upper belt running path, and the vertical roll support is located at the side of the press wheel support; And the front end of the vertical roll support is arranged with the vertical roll arranged in the vertical axis. The low height of the vertical roll surface is lower than the small floating height of the upper belt and the large height of the vertical roll surface is higher than the large floating height of the upper belt. In the conveying direction of the conveyor, the vertical roller support is arranged in front of the press wheel support. The two feet of the gantry structure of the pressure wheel support is arranged at the end of the connecting bottom plate connected to each other, the connecting bottom plate is located under the upper belt and the position of the conveyor parts between the avoidance arrangement, the vertical roller support is arranged in the cantilever shape in the connection of the bottom plate.
Belt conveyor with conveying, conveying distance is far, simple structure and easy to maintain, can easily implement program control and automatic operation, so as to be widely used in mining, raw materials, coal and other industries. When the belt conveyor is transporting the raw materials with more dust, it often produces large material dust at the material point of the belt conveyor, and the material dust will float into the air, thus causing pollution to the environment. It is the development trend of industry to advocate green production. Therefore, it is an urgent problem to avoid the material dust generated on the belt conveyor to float into the air.
