Description

Technical Field

[0001] This utility model relates to the field of rubber hose technology, and specifically to a wear-resistant rubber hose. Background Technology

[0002] In industrial production, rubber hoses are widely used for hydraulic conveying of plastic granules. However, the plastic granules cause severe wear to the inner wall of the rubber hose under the impact of high-speed water flow. Existing technologies usually delay wear by increasing the rubber thickness, but increasing the rubber thickness can lead to a decrease in flexibility, an increase in cost, and cannot solve the problem of local wear on the inner wall. In addition, the outer layer of the rubber hose lacks ground contact protection, and external wear reduces the service life of the rubber hose. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content

[0003] This invention provides a wear-resistant rubber tube to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a wear-resistant rubber tube, including a rubber tube body, the inner wall of the rubber tube body is provided with a spiral continuous protrusion structure, the cross-section of the protrusion structure is trapezoidal, the height of the trapezoid is 10%-20% of the inner diameter of the rubber tube body, and the length of the base of the trapezoid is 25%-35% of the inner diameter of the rubber tube body; the outer wall of the rubber tube body is integrally formed with multiple support strips along the length direction, the multiple support strips are evenly distributed along the circumference of the rubber tube body, and the outer surface of the support strips constitutes the lowest support point of the rubber tube body.

[0005] Preferably, the cross-section of the support strip is semi-circular, and the height of the support strip is 3%-6% of the outer diameter of the rubber tube.

[0006] Preferably, the surface of the raised structure is provided with a wear-resistant ceramic particle layer, the particle size of which is 80-150 mesh, covering 40%-60% of the surface area of ​​the raised structure.

[0007] Preferably, a transition adhesive layer is provided between the ceramic particle layer and the raised structure, and the adhesive layer is chloroprene rubber with added silane coupling agent.

[0008] Preferably, a metal mesh is embedded in the wall of the rubber tube.

[0009] The beneficial effects of this utility model are as follows: (1) By setting a spiral protrusion structure, this utility model can guide the water flow to form a vortex. Under the action of centrifugal force of the vortex, plastic particles with a density less than that of water will gather towards the center line of the rubber tube, reducing the frequency of contact between the particles and the tube wall and reducing wear. In addition, by setting a support strip to support the suspension of the rubber tube, the outer wall is prevented from directly rubbing against the ground, thereby extending the service life of the rubber tube; (2) The vortex effect enhances the fluid's ability to carry plastic particles and reduces the accumulation of particles in the rubber tube, thereby helping to reduce the risk of pipe blockage; (3) By setting a ceramic particle layer to directly bear wear, the wear of the protrusion structure can be delayed, further extending the service life.

[0013] The present invention will now be further described with reference to the accompanying drawings.

[0014] like Figure 1-2 As shown, this utility model provides a wear-resistant rubber tube, including a rubber tube body 1. The inner wall of the rubber tube body 1 is provided with a spiral continuous protrusion structure 2. The cross-section of the protrusion structure 2 is trapezoidal, the height of the trapezoid is 10%-20% of the inner diameter of the rubber tube body 1, and the length of the base of the trapezoid is 25%-35% of the inner diameter of the rubber tube body 1. The outer wall of the rubber tube body 1 is integrally formed with multiple support strips 3 along the length direction. The multiple support strips 3 are evenly distributed along the circumference of the rubber tube body 1. The outer surface of the support strips 3 constitutes the lowest support point of the rubber tube body 1. The cross-section of the support strips 3 is semi-circular, and the height of the support strips 3 is 3%-6% of the outer diameter of the rubber tube body 1.

[0015] Specifically, during use, the spiral protrusion structure 2 guides the water flow to form a vortex. The centrifugal force of the vortex causes the water to adhere to the outside, while plastic particles with a density less than water gather towards the centerline of the rubber tube 1. This reduces the contact frequency between the plastic particles and the inner wall of the rubber tube 1, thereby reducing the wear rate of the inner wall of the rubber tube 1 and extending the service life of the rubber tube. At the same time, the vortex effect enhances the fluid's ability to carry plastic particles, reducing the accumulation of particles inside the rubber tube, thus helping to reduce the risk of pipe blockage. In addition, the external support strip 3 can support the rubber tube 1 in the air, thereby reducing frictional corrosion between the outer wall of the rubber tube 1 and the ground, and extending the service life of the rubber tube.

[0016] In some embodiments, the surface of the protruding structure 2 is provided with a wear-resistant ceramic particle layer 4, the particle size of which is 80-150 mesh, covering 40%-60% of the surface area of ​​the protruding structure 2. Specifically, during use, the ceramic particle layer 4 directly bears the wear, thereby delaying the wear of the protruding structure 2 and extending the service life of the rubber tube.

[0017] In some embodiments, a transition adhesive layer 5 is provided between the ceramic particle layer 4 and the protruding structure 2. This adhesive layer is chloroprene rubber with added silane coupling agent. Specifically, the adhesive layer with added silane coupling agent can enhance the chemical bonding force between the ceramic particles and the rubber, thereby reducing the occurrence of ceramic particle detachment under high temperature and high pressure conditions.

[0018] In some embodiments, a metal mesh 6 is embedded in the wall of the rubber tube 1. The metal mesh 6 can enhance the compressive and tensile properties of the rubber tube 1, thereby preventing the tube wall from deforming due to pressure or tension.

[0019] The above embodiments can be combined with each other.

[0020] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
