[0001] The present application relates to the technical field of conveyor belts, and in particular to a novel flame-retardant conveyor belt and a preparation method thereof. Background Art

[0002] With the rapid development of modern industry, especially in coal, metallurgy, chemical industry and other industries, flame retardant conveyor belts are key material transportation equipment, and their performance stability and safety are increasingly valued. Under long-term and high-intensity working conditions, conveyor belts not only need to bear the weight and friction of materials, but also need to cope with complex and changeable working conditions, such as high temperature, humidity, corrosive media, etc. Therefore, developing a conveyor belt with excellent flame retardant properties, good heat dissipation capacity and long life is of great significance to ensure production safety and improve transportation efficiency.

[0003] Traditional flame-retardant conveyor belts are usually made of high-strength fibers such as nylon and polyester as the skeleton material, and the surface is covered with flame-retardant rubber or PVC and other materials. This type of conveyor belt has been designed with certain flame-retardant properties in mind, and flame retardants such as antimony trioxide and chlorinated paraffin are added to achieve heat absorption and flame blocking during combustion.

[0004] However, although these measures have improved the flame retardant properties of the conveyor belt to a certain extent, the internal temperature of the conveyor belt will still gradually rise due to the heat generated by friction and material transfer during long-term use. The accumulation of internal heat accelerates the thermal aging process of the conveyor belt material, reduces the mechanical properties and flame retardant properties of the material, and shortens the service life of the conveyor belt. Summary of the invention

[0005] The purpose of the present application is to solve the problem that during long-term use, the accumulation of heat inside the conveyor belt accelerates the thermal aging process of the conveyor belt material, reduces the mechanical properties and flame retardant properties of the material, and shortens the service life of the conveyor belt.

[0032] When in use, firstly, the conveyor belt 4 is set to carry the high-temperature raw materials, and then the driving motor 14 is started to drive the worm 13 to rotate, and the worm 13 is driven to mesh with the worm wheel 12, and the worm wheel 12 is driven to drive the driving roller 2 to rotate, so that the driving roller 2 cooperates with the conveyor belt 4 to drive the driven roller 3 to rotate synchronously, and then the conveyor belt 4 forms a circular movement with the driving roller 2 and the driven roller 3 as the fulcrum, and the high-temperature raw materials carried on the top of the conveyor belt 4 are transported; When the transmission belt 4 is circulated with the driving roller 2 and the driven roller 3 as the fulcrum, one end of the transmission belt 4 passes through between the hollow heat exchange roller 5 and the bonding roller 6, and at the same time, the driven roller 3 drives the transmission wheel 17 to rotate, and the transmission wheel 17 drives one end of the transmission rod 18 to eccentrically deflect, and at the same time, the other end of the transmission rod 18 drives the transmission wheel 2 19 to rotate synchronously with the transmission wheel 17, and then the transmission wheel 2 19 drives a bonding roller 6 to drive the synchronous gear 15 to rotate, and at the same time, one synchronous gear 15 drives the synchronous gear 2 16 to mesh synchronously with another synchronous gear 15, and then the synchronous gear 15 and the synchronous gear 2 16 simultaneously drive the hollow heat exchange roller 5 and the bonding roller 6 to rotate, thereby reducing the resistance of the transmission belt 4 when passing between the hollow heat exchange roller 5 and the bonding roller 6, so that the transmission belt 4 can smoothly pass between the hollow heat exchange roller 5 and the bonding roller 6, and reduce the wear of the transmission belt 4 when passing between the hollow heat exchange roller 5 and the bonding roller 6; At the same time, by starting the vacuum pump 9 connected to the external liquid nitrogen storage tank, the nitrogen enters the interior of the hollow heat exchange roller 5 through the air guide pipe 1 8, and at the same time, the nitrogen passes through the hollow heat exchange roller 5 and the conveyor belt 4 passing through the hollow heat exchange roller 5 and the laminating roller 6 to form a rapid heat exchange, so as to reduce the temperature of the surface of the conveyor belt 4, and then the nitrogen after heat exchange is introduced into the drainage gas collecting tank 11 through the air guide pipe 2 10 for collection, and when the nitrogen passes through the interior of the hollow heat exchange roller 5, it collides with the surface of the spiral drainage ring 7, and spirally passes through the interior of the hollow heat exchange roller 5 along the guiding direction of the spiral drainage ring 7, so as to improve the nitrogen and the hollow heat exchange roller 5. The contact area of ​​the hollow heat exchange roller 5 is increased, and the heat exchange efficiency of the nitrogen passing through the hollow heat exchange roller 5 and the conveyor belt 4 is improved. At the same time, the transmission mechanism drives the rotation of the hollow heat exchange roller 5 and the laminating roller 6, which effectively increases the contact heat exchange area between the hollow heat exchange roller 5 and the conveyor belt 4, and further improves the heat exchange and cooling efficiency of the conveyor belt 4. This makes it easier to use the nitrogen to pass through the hollow heat exchange roller 5 and the conveyor belt 4 for contact heat exchange and cooling, so as to quickly achieve heat dissipation on the surface of the conveyor belt 4, thereby reducing the heat accumulation inside the conveyor belt 4, delaying the thermal aging process of the conveyor belt 4, maintaining the flame retardant performance of the conveyor belt 4, and extending the service life of the conveyor belt 4.

[0033] Reference Figure 1 and Figure 2 One end of the driving roller 2 and the driven roller 3 are symmetrically fixedly connected with an anti-skid tooth ring 20, and the inner side of the transmission belt 4 is symmetrically provided with an anti-skid tooth groove 21 meshing with the anti-skid tooth ring 20.

[0034] During use, when the driving component is started to drive the transmission belt 4 to move in a circular motion with the driving roller 2 and the driven roller 3 as the fulcrum, the driving roller 2 and the driven roller 3 drive the anti-skid tooth ring 20 to engage with the anti-skid tooth groove 21, and the engagement and friction between the anti-skid tooth ring 20 and the anti-skid tooth groove 21 are used to push the transmission belt 4 to move with the driving roller 2 and the driven roller 3 as the fulcrum, thereby effectively improving the connection strength and stability between the transmission belt 4 and the driving roller 2 and the driven roller 3, and effectively improving the anti-skid effect between the transmission belt 4 and the driving roller 2 and the driven roller 3.

[0035] Reference Figure 1 and Figure 2 The interior of the U-shaped base 1 is evenly rotated and connected with a plurality of support rollers 22 , and the support rollers 22 form rolling resistance with the inner top of the conveyor belt 4 .

[0036] During use, when the top of the conveyor belt 4 carries raw materials, the raw materials squeeze the top of the conveyor belt 4 under the action of gravity to cause deformation, and a rolling friction is formed between the conveyor belt 4 and the support roller 22, so that the support roller 22 forms a rolling support for one end of the conveyor belt 4, thereby effectively improving the bearing strength and stability of the conveyor belt 4.

[0037] Reference Figure 1 and Figure 2 A glass fiber cloth 23 is fixedly connected to the surface of the conveyor belt 4.

[0038] When in use, by arranging the glass fiber cloth 23 on the surface of the conveyor belt 4, the conveyor belt 4 forms indirect contact with the material through the glass fiber cloth 23, and the glass fiber cloth 23 is resistant to high temperature, anti-corrosion, and fire retardant, which effectively improves the thermal stability and service life of the conveyor belt 4.
