Description

Technical Field

[0001] This utility model relates to the field of rubber conveyor belt production technology, and in particular to a heat-resistant rubber conveyor belt. Background Technology

[0002] In the field of rubber conveyor belts, heat resistance and heat dissipation performance have always been key factors limiting their service life and application range. In existing technologies, conveyor belts operating in high-temperature environments often suffer damage such as peeling and blistering due to poor heat resistance and inadequate heat dissipation, resulting in a significantly shortened service life. This is particularly true in high-temperature material conveying scenarios such as steel, coking, and cement industries, where conveyor belts must withstand high temperatures for extended periods, making their heat resistance and heat dissipation performance especially crucial. Therefore, developing a rubber conveyor belt with good heat resistance and excellent heat dissipation performance is of great significance for improving the service life of conveyor belts and expanding their application range. Utility Model Content

[0003] The main objective of this invention is to provide a heat-resistant rubber conveyor belt to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A heat-resistant rubber conveyor belt includes a flame-retardant layer, a reinforcing layer, and a wear-resistant layer connected sequentially from top to bottom by an adhesive layer. A heat dissipation layer is disposed between the flame-retardant layer and the reinforcing layer, and a flexible steel wire hose is embedded within the heat dissipation layer. The flexible steel wire hose is inclined relative to the length direction of the conveyor belt, and its two ends respectively form an open first port and a second port. Multiple annular support members are spaced apart along the axial direction inside the flexible steel wire hose.

[0006] Furthermore, the steel wire hose includes a first section, a second section, and a third section that are connected in sequence and extend in a straight line. The first and third sections are parallel to each other and form an angle β of 30°-50° with respect to the length direction of the conveyor belt. The second section is perpendicular to the length direction of the conveyor belt.

[0007] Furthermore, the first pipe segment and the second pipe segment are connected by a first arc-shaped connecting segment, and the second pipe segment and the third pipe segment are connected by a second arc-shaped connecting segment.

[0008] Furthermore, the ends of both the first and second pipe openings are covered with metal filter screens.

[0009] Furthermore, the heat dissipation layer is made of silicone rubber or fluororubber.

[0010] This invention also includes other components that enable the heat-resistant rubber conveyor belt to function properly, and these devices or components all employ conventional techniques in the art. Furthermore, devices and components not limited in this invention all employ conventional techniques in the art, such as the flame-retardant layer, reinforcing layer, and wear-resistant layer mentioned in this application. In specific implementation, appropriate equipment or component models can be selected according to the specific working scenario.

[0011] The working principle of this invention is as follows: When the conveyor belt runs along the conveying direction, due to the special shape and structure of the steel wire hose, air flows in from the first port and then flows out from the second port. This process accelerates the removal of heat generated by the conveyor belt, thereby effectively improving heat dissipation performance. When the conveyor belt rotates in the reverse direction, air flows in from the second port and out from the first port, achieving the same good heat dissipation effect, thus broadening the application range of the conveyor belt.

[0012] In addition, both the ends of the first and second pipe openings are covered with metal filter screens, which effectively prevent foreign objects from entering the steel wire hose and causing blockage, ensuring smooth heat dissipation. Meanwhile, multiple annular support members spaced axially inside the steel wire hose provide support, preventing blockage due to pressure even when heavy objects are placed on the conveyor belt, thus ensuring effective heat dissipation.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Improved heat resistance and extended service life: By setting up a heat dissipation layer and the steel wire hose embedded in the heat dissipation layer, the heat dissipation speed of the conveyor belt can be effectively accelerated, avoiding damage caused by high temperature causing the conveyor belt to peel and blister. This significantly improves the heat resistance of the conveyor belt, enabling it to operate stably in high temperature environments, reducing damage caused by overheating, thereby greatly extending the service life of the conveyor belt and reducing the cost of use.

[0015] 2. Expanding the scope of application: The conveyor belt can maintain good heat dissipation even when rotating in the reverse direction, which expands the scope of application of the conveyor belt and makes it able to adapt to more different working conditions. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Example:

[0021] like Figures 1-2 As shown, a heat-resistant rubber conveyor belt includes a flame-retardant layer 1, a reinforcing layer 3, and a wear-resistant layer 4 connected sequentially from top to bottom by an adhesive layer 5. A heat dissipation layer 2 is disposed between the flame-retardant layer 1 and the reinforcing layer 3, and a steel wire hose 6 is embedded within the heat dissipation layer 2. The steel wire hose 6 is inclined relative to the length direction of the conveyor belt, and its two ends are respectively formed with an open first port 7 and a second port 8. Multiple annular support members 10 are arranged axially at intervals inside the steel wire hose 6.

[0022] Specifically, the flexible steel wire hose 6 includes a first section 61, a second section 62, and a third section 63 that extend in a straight line and are connected sequentially. The first section 61 and the third section 63 are parallel to each other and form an angle β of 30°-50° with respect to the length direction of the conveyor belt. The second section 62 is perpendicular to the length direction of the conveyor belt. The first section 61 and the second section 62 are connected by a first arc-shaped connecting section, and the second section 62 and the third section 63 are connected by a second arc-shaped connecting section. The heat dissipation layer 2 is made of silicone rubber or fluororubber.

[0023] In addition, the ends of the first port 7 and the second port 8 are both covered with metal filter screens 9.

[0024] Among them, the flame retardant layer 1 is composed of chopped glass fiber filaments and flame retardant adhesive, and the bonding layer 5 is made of high-temperature adhesive.

[0025] The working principle of this heat-resistant rubber conveyor belt is as follows: When the conveyor belt runs in the conveying direction, due to the special shape and structure of the steel wire hose 6, air flows in from the first port 7 and then flows out from the second port 8. This process accelerates the removal of heat generated by the conveyor belt, thereby effectively improving heat dissipation performance. When the conveyor belt rotates in the reverse direction, air flows in from the second port 8 and flows out from the first port 7, achieving the same good heat dissipation effect and thus broadening the application range of the conveyor belt.

[0026] Furthermore, both the ends of the first port 7 and the second port 8 are covered with metal filter screens 9, which can effectively prevent foreign objects from entering the steel wire hose 6 and causing blockage, ensuring the smooth progress of the heat dissipation process. At the same time, multiple annular support members 10 arranged axially within the steel wire hose 6 can provide support for the steel wire hose 6, so that even if heavy objects are placed on the conveyor belt, the steel wire hose 6 will not be blocked due to pressure, thus affecting the heat dissipation effect.

[0027] The above embodiments are merely descriptions of preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope of the present utility model.
