Description

Technical Field

[0001] This utility model relates to the field of flame-retardant conveyor belt technology, and in particular to a high-strength solid-core flame-retardant conveyor belt. Background Technology

[0002] Flame-retardant conveyor belts are a type of conveyor belt with special properties, mainly used in industries such as coal mines, mining, and chemical plants to prevent the occurrence and spread of fires. Solid-woven flame-retardant conveyor belts use a one-piece woven structure without layers. This gives the conveyor belt high strength and stability, enabling it to withstand greater tensile and impact forces. The core of the conveyor belt is typically made of synthetic fiber materials with good flame-retardant properties, such as polyester and nylon. These materials have high strength and wear resistance, as well as good flame-retardant properties.

[0003] Traditionally, coal mine PVC flame-retardant conveyor belts are produced by impregnating the entire belt crown with glue, followed by coating and plasticizing in a plasticizing box. Traditionally, coal mine PG flame-retardant conveyor belts are produced by impregnating and plasticizing the entire belt core, then applying double-layer glue to the top and bottom of the semi-plastic core, and finally molding to achieve the desired texture and finish.

[0004] However, the core of traditional conveyor belts typically uses a single material or a relatively simple combination of fibers, resulting in a relatively simple structure. For example, it may use ordinary canvas or synthetic fiber core, with a loose fiber arrangement that lacks sufficient compactness and integrity. This structure is prone to fiber slippage and breakage when subjected to tensile forces, leading to a reduction in the strength of the conveyor belt. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-strength solid core flame-retardant conveyor belt, which aims to improve the problem that the core of traditional conveyor belts is prone to fiber slippage and breakage when subjected to tensile force, resulting in a reduction in the strength of the conveyor belt.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength solid core flame-retardant conveyor belt, including a conveyor belt skeleton, a plurality of belt cores fixedly connected inside the conveyor belt skeleton, an inner core covering component inside the belt core, a flame retardant component inside the belt core, and a reinforcing component inside the belt core;

[0007] The inner core covering assembly includes polyvinyl chloride paste resin and polyvinyl chloride suspension resin, wherein the polyvinyl chloride paste resin is disposed inside the core and the polyvinyl chloride suspension resin is disposed inside the core. The flame retardant assembly includes pentabromophenyl acrylate and Dow organothiol methyltin heat stabilizer, wherein the polybromophenyl acrylate and the Dow organothiol methyltin heat stabilizer are disposed inside the core.

[0008] Furthermore, the reinforcing component includes a reinforcing core, which is fixedly connected inside the strip core.

[0009] Furthermore, the outer wall of the core is provided with an antistatic layer.

[0010] Furthermore, the antistatic layer is disposed inside the conveyor belt frame.

[0011] Furthermore, the conveyor belt frame is provided with an upper composite layer inside.

[0012] Furthermore, a lower composite layer is provided inside the conveyor belt frame.

[0013] Furthermore, the upper composite layer and the lower composite layer are respectively disposed on the upper and lower surfaces of the core.

[0014] Furthermore, an inner core layer is provided between the upper composite layer and the lower composite layer.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the entire belt core is first fully impregnated by polyvinyl chloride suspension resin and polyvinyl chloride paste resin, which improves the bonding strength between the cover core, extends the service life, and protects the belt core from external environmental erosion, such as avoiding the effects of moisture, dust, wear, etc. It can penetrate into the belt core, enhance the strength and integrity of the belt core, and at the same time improve the flame retardant performance of the conveyor belt.

[0017] 2. In this utility model, the upper composite layer protects the belt core and other structures of the conveyor belt from wear and erosion by the conveyed materials, the lower composite layer reduces friction and wear between the conveyor belt and the idler or guide rail, and improves the operating efficiency and stability of the conveyor belt, while the inner core layer further enhances the tear resistance of the belt core.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a high-strength solid core flame-retardant conveyor belt, including a conveyor belt skeleton 1. The conveyor belt skeleton 1 can withstand various tensile, compressive and bending forces on the conveyor belt during transportation. Multiple belt cores 2 are fixedly connected inside the conveyor belt skeleton 1. The belt cores 2 are woven from multiple layers of fabric or chemical fiber materials and have high strength and toughness. An inner core covering component is provided inside the belt cores 2. A flame retardant component is provided inside the belt cores 2. A reinforcing component is provided inside the belt cores 2.

[0026] The inner core covering assembly includes polyvinyl chloride paste resin 3 and polyvinyl chloride suspension resin 4. Polyvinyl chloride paste resin 3 is disposed inside the core 2, and polyvinyl chloride suspension resin 4 is disposed inside the core 2. Polyvinyl chloride suspension resin 4 has good flame retardancy, abrasion resistance, corrosion resistance and insulation properties. The flame retardant assembly includes pentabromophenyl acrylate 5 and Dow organothiol methyl tin heat stabilizer 6. Polybromophenyl acrylate 5 is disposed inside the core 2. Polybromophenyl acrylate 5 is a high-efficiency flame retardant with good thermal stability and flame retardant properties. Dow organothiol methyl tin heat stabilizer 6 is disposed inside the core 2.

[0027] Specifically, in this flame-retardant conveyor belt, the conveyor belt skeleton 1 serves as the basic support structure, giving the conveyor belt its basic shape and frame. The belt core 2, as the main load-bearing component, plays a crucial role in the operation of the conveyor belt. Polyvinyl chloride (PVC) suspension resin 4 enhances the physical and mechanical properties of the covering material, effectively protecting the belt core 2 from external environmental factors such as moisture penetration, dust contamination, and abrasion. As an impregnating material, PVC suspension resin 4 penetrates into the interior of the belt core 2, strengthening its strength, making it more stable, and improving its overall integrity. Simultaneously, it also enhances the flame-retardant properties of the conveyor belt, ensuring safe use in flammable environments. Polyvinyl chloride paste resin 3 can fully impregnate the integral belt core 2, greatly improving the bonding strength between the cover and the core, thereby extending the service life of the conveyor belt. Poly(pentabromophenyl acrylate) 5 has good thermal stability and flame retardant properties. It can work with other materials in the conveyor belt to further improve the flame retardant effect of the conveyor belt. When the conveyor belt encounters a fire source, it can promote the rapid self-extinguishing of the conveyor belt, effectively reducing the occurrence and spread of fire. Dow organothiol methyltin heat stabilizer 6 has excellent thermal stability and processing performance. In high-strength solid woven flame retardant conveyor belts, it can be used together with materials such as polyvinyl chloride to improve the thermal stability of the conveyor belt and prevent problems such as deformation and aging of the conveyor belt in high-temperature environments.

[0028] Reference Figure 3 and 4 The reinforcing components include a reinforcing core 8, which is made of high-strength fiber or metal materials, such as steel wire rope or glass fiber. The reinforcing core 8 is fixedly connected inside the belt core 2. An antistatic layer 7 is provided on the outer wall of the belt core 2. The antistatic layer 7 is formed by adding conductive materials or antistatic agents to the material of the conveyor belt. The antistatic layer 7 is provided inside the conveyor belt skeleton 1. An upper composite layer 9 and a lower composite layer 10 are provided inside the conveyor belt skeleton 1. The upper composite layer 9 and the lower composite layer 10 are respectively provided on the upper and lower surfaces of the belt core 2. An inner core layer 11 is provided between the upper composite layer 9 and the lower composite layer 10.

[0029] Specifically, the antistatic layer 7 effectively conducts away the static electricity generated by the conveyor belt during operation, thus preventing the accumulation of static electricity and the occurrence of discharge phenomena. The reinforcing core 8 significantly enhances the tensile strength, impact strength, and tear strength of the conveyor belt, enabling it to withstand greater loads and harsher working conditions. The upper composite layer 9 protects the belt core 2 and other structures from wear and erosion by the conveyed materials. The lower composite layer 10 reduces friction and wear between the conveyor belt and idlers or guide rails, thereby improving the operating efficiency and stability of the conveyor belt. The inner core layer 11 further enhances the tear resistance of the belt core 2.

[0030] Working Principle: In this flame-retardant conveyor belt, the conveyor belt skeleton 1 is the basic support structure, providing the basic shape and frame of the conveyor belt. The belt core 2 is the main load-bearing structure. Polyvinyl chloride suspension resin 4 improves the physical and mechanical properties of the covering material, protecting the belt core 2 from external environmental erosion, such as moisture, dust, and abrasion. As an impregnating material, it can penetrate into the belt core 2, enhancing its strength and integrity, while also improving the flame-retardant performance of the conveyor belt, ensuring safe use in flammable environments. Polyvinyl chloride paste resin 3 fully impregnates the entire belt core 2, improving the bonding strength between the cover and the core, and extending its service life. Poly(pentamyl methacrylate) 5 has good thermal stability and flame-retardant properties. It can work in conjunction with other materials in the conveyor belt to improve its flame-retardant effect, enabling it to self-extinguish quickly when exposed to a fire source, reducing the occurrence and spread of fire. Dow organothiol methyl tin heat stabilizer 6 has good thermal stability and processing performance. In high-strength solid woven flame-retardant conveyor belts, it can be used in conjunction with materials such as polyvinyl chloride to improve the thermal stability of the conveyor belt and prevent deformation and aging in high-temperature environments. The antistatic layer 7 can effectively conduct away the static electricity generated during the operation of the conveyor belt in a timely manner, avoiding the accumulation and discharge of static electricity. The reinforcing core 8 enhances the tensile strength, impact strength, and tear strength of the conveyor belt, enabling it to withstand greater loads and harsher working environments. The upper composite layer 9 protects the belt core 2 and other structures from wear and erosion by the conveyed materials. The lower composite layer 10 reduces friction and wear between the conveyor belt and idlers or guide rails, improving the operating efficiency and stability of the conveyor belt. The inner core layer 11 further enhances the tear resistance of the belt core 2.
