Description

Technical Field

[0001] The utility model belongs to the technical field of conveyor belts, in particular to a highly wear-resistant and oil-resistant conveyor belt. Background Art

[0002] Conveyor belts are composite products of rubber, fiber, metal, or plastic and fabric used in conveyor belts to carry and transport materials. Conveyor belts are widely used in cement, coking, metallurgy, chemical industry, steel and other industries where the conveying distance is short and the conveying volume is small.

[0003] When transporting coal, the surface of the traditional conveyor belt will absorb the oil on the surface of the coal, and the oil is mixed with a lot of corrosive impurities. After a long period of transportation, the surface of the conveyor belt is prone to pitting and corrosion. At the same time, the surface of the ore is hard, and when it comes into contact with the surface of the conveyor belt, it is easy to cause further wear on the surface, affecting the normal use of the conveyor belt. Summary of the invention

[0004] The purpose of the utility model is to solve the above problems and provide a highly wear-resistant and oil-resistant conveyor belt, which is easy to guide oil and more wear-resistant.

[0005] The purpose of the utility model is achieved in this way:

[0006] A highly wear-resistant and oil-resistant conveyor belt, which includes an upper rubber layer, a woven layer and a bottom rubber layer from top to bottom, and the upper rubber layer, the woven layer and the bottom rubber layer are connected by surface brushing and hot pressing. A plurality of oil conveying grooves are opened on the upper surface of the upper rubber layer, and a guide surface extending toward both ends of the oil conveying groove and gradually decreasing in horizontal height is formed in the middle of each oil conveying groove. An oleophobic layer is arranged on the inner groove wall and the guide surface of the oil conveying groove. The longitudinal cross-section of the oil conveying groove is "V"-shaped, and the groove width gradually increases from the middle of the oil conveying groove to the two ends of the oil conveying groove.

[0007] The utility model is further configured such that the thickness of the upper rubber layer is 6 mm to 7 mm, the thickness of the braided layer is 0.5 mm to 1 mm, and the thickness of the bottom rubber layer is 3 mm to 5 mm.

[0008] The utility model is further configured such that the height difference between the middle of the oil conveying groove and the top of the upper rubber layer is 3 mm, and the height difference between the two ends of the oil conveying groove and the top of the upper rubber layer is 5 mm.

[0009] The utility model is further configured that a hardening layer is provided on the top of the upper glue layer, and the thickness of the hardening layer is 1.5 mm to 2 mm.

[0010] The utility model is further configured that a wear-resistant ceramic sheet is arranged on the upper surface of the hardened layer, and the wear-resistant ceramic sheet and the hardened layer are connected by hot pressing in the form of gluing on the upper and lower sides of the canvas.

[0011] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects:

[0012] 1. The conveyor belt provided by the utility model utilizes the oil conveying groove opened on the upper surface of the upper rubber layer to guide the oil for the coal in transportation, and also utilizes the guide surfaces of different heights to further guide the oil; the "V"-shaped oil conveying groove structure is adopted, so that the surface is not easy to tip over when transporting coal, and the structural strength is stronger and not easy to be blocked.

[0013] 2. The utility model further provides a hardening layer on the top of the adhesive layer, which is hardened by burning to improve the wear resistance, and the wear resistance is further improved by providing a wear-resistant ceramic sheet on the surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below with reference to the accompanying drawings. Figure 1 — Figure 2 :

[0021] A highly wear-resistant and oil-resistant conveyor belt, which includes an upper rubber layer 1, a woven layer 2 and a bottom rubber layer 3 from top to bottom, and the upper rubber layer 1, the woven layer 2 and the bottom rubber layer 3 are connected by surface brushing and hot pressing. A plurality of oil conveying grooves 10 are opened on the upper surface of the upper rubber layer 1, and a guide surface 11 extending toward both ends of the oil conveying groove 10 and gradually decreasing in horizontal height is formed in the middle of each oil conveying groove 10. An oleophobic layer 12 is arranged on the inner groove wall of the oil conveying groove 10 and the guide surface 11. The longitudinal cross-section of the oil conveying groove 10 is "V"-shaped, and the groove width from the middle of the oil conveying groove 10 to the two ends of the oil conveying groove 10 gradually increases.

[0022] When transporting mineral resources, the oil on the surface of the mineral flows into the oil conveying tank 10, and the inclined guide surface 11 is used to allow the oil to flow out from both sides, and the oleophobic layer 12 is provided to enhance the fluidity of the oil.

[0023] In the above structure, the longitudinal cross-section of the oil conveying trough 10 is "V"-shaped, which can not only enhance the supporting capacity of the upper rubber layer, making it less likely to be overturned by the pressure of minerals, but also enhance the structural strength; in addition, the cross-section can drive the oil to the two ends during the movement of the conveyor belt, thereby producing an oil drainage effect.

[0024] Preferably, the thickness of the upper rubber layer 1 is 6 mm to 7 mm, the thickness of the braided layer 2 is 0.5 mm to 1 mm, and the thickness of the bottom rubber layer 3 is 3 mm to 5 mm.

[0025] Preferably, the height difference between the middle of the oil conveying groove 10 and the top of the upper rubber layer 1 is 3 mm, and the height difference between the two ends of the oil conveying groove 10 and the top of the upper rubber layer 1 is 5 mm.

[0026] Preferably, a hardening layer 4 is provided on the top of the adhesive layer 1, and the thickness of the hardening layer 4 is 1.5 mm to 2 mm.

[0027] In the above structure, the hardening layer 4 is formed by carbonizing and oxidizing the upper surface of the upper rubber layer to make the surface material harder, thereby producing a wear-resistant effect. The material of the upper rubber layer is chloroprene rubber.

[0028] Preferably, the upper surface of the hardened layer 4 is provided with a wear-resistant ceramic sheet 5, and the wear-resistant ceramic sheet 5 is hot-pressed with the hardened layer 4 by gluing the upper and lower sides of the canvas. The wear-resistant ceramic sheet is further bonded to the upper surface of the hardened layer to further enhance the wear resistance, and the hardened layer serves as a bottom layer protection to prevent the woven layer 2 under the upper glue layer 1 from being worn.

[0029] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
