Description
Technical Field
[0001] This utility model relates to the field of air blowing device technology, specifically an air blowing device for producing high-pressure hoses. Background Technology
[0002] High-pressure hoses are flexible pipes capable of withstanding high pressure and are widely used in industries such as industrial construction machinery, petrochemicals, and aerospace to transport liquids, gases, or mixed media. High-pressure hoses typically consist of a multi-layered composite structure and mainly include the following components:
[0003] Inner layer: In direct contact with the conveyed medium, it needs to be corrosion-resistant and wear-resistant (common materials: nitrile rubber, polyurethane, fluororubber, etc.);
[0004] Reinforcing layer: a critical load-bearing component, typically made of high-strength steel wire woven or wound (stainless steel wire, polyester fiber, aramid fiber, etc.).
[0005] Outer layer: Protective layer, resistant to wear and environmental corrosion (such as neoprene rubber, polyvinyl chloride, etc.).
[0006] In the production process of high-pressure hoses, the inner layer formed by the extruder needs to be cooled in a water tank before being transported to the next station for the winding of the reinforcing layer. During this process, in order to avoid water stains remaining on the outer wall of the inner layer affecting the winding work, an air blowing device is needed to blow water off the outer wall of the inner layer that passes through the water tank. Based on this, in order to achieve all-round water removal of the inner layer surface, a high-pressure hose production air blowing device is provided. Utility Model Content

[0027] 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.
[0028] Please see Figures 1-3 In this embodiment of the present invention, a high-pressure hose production air blowing device includes an air blowing assembly 2 for blowing air onto the surface of the hose body 1. The air blowing assembly 2 includes a spiral blowing unit and a water guiding unit.
[0029] The spiral jet unit is used to guide airflow to spray air onto the surface of the hose body 1 in all directions;
[0030] The water guiding unit is used to intercept and guide the water droplets blown by the spiral jet unit;
[0031] The spiral jet unit includes a spiral tube 201, a jet nozzle 202, and an air inlet pipe 203;
[0032] The main body of the hose 1 extends through the middle area of the spiral tube 201. The nozzle 202 is fixed to the outer side of the spiral tube 201 and communicates with the inner cavity of the spiral tube 201. Multiple nozzles 202 are provided and are evenly distributed along the spiral trajectory of the spiral tube 201.
[0033] The air inlet pipe 203 is fixed to one end of the spiral tube 201. The end of the spiral tube 201 away from the air inlet pipe 203 is blocked. The air inlet pipe 203 is connected to the air pump through an external pipeline. The airflow ejected through multiple spirally distributed nozzles 202 is used to spray the surface of the hose body 1 in all directions.
[0034] Multiple nozzles 202 are tilted toward the surface of the hose body 1, and the multiple nozzles 202 are distributed in a staggered manner along the ring.
[0035] In this embodiment, it should be noted that the air blowing assembly 2 is installed at the rear end of the hose cooling water tank via a bracket, and the hose body 1 formed by the extruder passes through the cooling water tank and the middle area of the spiral tube 201 in sequence.
[0036] During this process, an external air pump is started simultaneously, which delivers high-pressure air to the air inlet pipe 203, then into the spiral tube 201, and then sprays it out through multiple nozzles 202 to blow air onto the surface of the hose body 1. Through the spirally distributed multiple nozzles 202, the entire surface of the hose body 1 can be blown away, thereby blowing away water droplets on the surface of the hose body 1 and achieving efficient water removal.
[0037] Please refer to this carefully. Figures 1-3 The water guiding unit includes a spiral back plate 204 and a spiral arc-shaped guide groove 205;
[0038] The spiral back plate 204 is fixed to the spiral tube 201 on the side away from the nozzle 202, and the spiral arc-shaped guide groove 205 is integrally formed on the inner ring side of the spiral back plate 204.
[0039] The spiral arc-shaped guide grooves 205 are distributed on the side of the spiral back plate 204 away from the spiral tube 201;
[0040] The spiral backplate 204 is used to intercept water droplets blown up by the rear nozzle 202, and the spiral arc-shaped guide groove 205 is used to guide the water droplets flowing downward along the surface of the spiral backplate 204.
[0041] The inner diameter of the spiral arc guide groove 205 is larger than the outer diameter of the hose body 1, and the outer ring outer diameter of the spiral back plate 204 is larger than the track outer diameter of the spiral tube 201.
[0042] In this embodiment: during the process of blowing water off the surface of the hose body 1, the airflow blown out by the nozzle 202 located at the rear end of the spiral back plate 204 blows up the water on the surface of the hose body 1, and the splashed water droplets hit the rear end face of the spiral back plate 204, thus achieving the interception of splashed water droplets.
[0043] The intercepted water droplets flow downwards along the surface of the spiral back plate 204 and the spiral arc guide groove 205, and then flow downwards along the trajectory of the spiral arc guide groove 205. This effectively prevents splashed water droplets from falling back onto the surface of the hose body 1, further improving the water removal effect and efficiency.
[0044] Please refer to this carefully. Figures 1-3 The spiral back plate 204 and the spiral arc-shaped guide groove 205 are integrally molded from PVC material. The spiral back plate 204 and the spiral tube 201 are fixed by glue or ultrasonic welding.
[0045] In this embodiment, the overall structure of the spiral back plate 204 is simple to manufacture and easy to assemble and fix with the spiral tube 201, which facilitates production and promotion.
[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
