Description

Technical Field

[0001] This utility model relates to the field of steel strip pipe technology, and more specifically, to a wear-resistant perforated steel strip pipe. Background Technology

[0002] Currently, sewage needs to be discharged through steel strip pipes, also known as steel strip spiral pipes. These pipes are made by adding steel strips to plastic pipes. Buried drainage steel strip reinforced spiral corrugated pipes use high-density polyethylene as the base material and steel strips coated with adhesive resin to form a waveform as the main support structure. They are then wound and combined with polyethylene material to form a whole double-walled spiral corrugated pipe. The materials used include polyethylene, steel strips, and adhesive resin.

[0003] However, in actual use, it is prone to breakage after being subjected to external impact or after long-term use, which affects its service life. At the same time, conventional steel strip pipes also have insufficient heat resistance and waterproof properties, making it difficult to meet the requirements of some application scenarios with high environmental conditions. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wear-resistant perforated steel strip tube to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wear-resistant perforated steel strip tube includes an outer tube, a steel strip layer fixedly disposed on the inner wall of the outer tube, an inner tube fixedly disposed on the inner wall of the steel strip layer, a plurality of through holes being formed on the surface of the steel strip layer, and a reinforcing mechanism being disposed inside the outer tube.

[0007] The strengthening mechanism includes multiple fixing grooves opened inside the external tube, and reinforcing steel bars are fixedly installed inside each of the multiple fixing grooves. Multiple reinforcing rings are fixedly installed on the surface of the reinforcing steel bars, and multiple outer rings are fixedly installed on the outside of the external tube. The reinforcing rings are made of carbon steel.

[0008] By adopting the above technical solution, the reinforcing steel bars inside the external pipe are welded and fixed at both ends, which enhances the overall rigidity of the pipeline. Moreover, the carbon steel reinforcing ring cooperates with the outer ring to improve the pipeline's pressure resistance and impact resistance, thereby effectively resisting external forces, ensuring stable operation of the pipeline under complex working conditions, and extending its service life.

[0009] As a further description of the above technical solution: the inner wall of the built-in tube is provided with an auxiliary mechanism, the auxiliary mechanism including a heat-resistant layer fixedly disposed on the inner wall of the built-in tube, and a wear-resistant layer fixedly disposed on one side of the inner heat-resistant layer;

[0010] The inner heat-resistant layer is made of ceramic fiber, and the wear-resistant layer is made of polyurethane.

[0011] By adopting the above technical solution, the heat-resistant layer and the wear-resistant layer work together to make the built-in pipe both heat-resistant and wear-resistant, thereby improving the overall performance of the pipeline.

[0012] As a further description of the above technical solution: an external heat-resistant layer is fixedly provided on the surface of the external tube, and a waterproof layer is fixedly provided on one side of the external heat-resistant layer. The external heat-resistant layer is made of glass fiber material, and the waterproof layer is made of polyvinyl chloride material.

[0013] The through holes are arranged in an array on the surface of the steel strip layer, and the two ends of the reinforcing steel bars extend to the two ends of the external tube, and the reinforcing steel bars and the ends of the external tube are fixed by welding.

[0014] By adopting the above technical solutions: the outer heat-resistant layer made of fiberglass can resist high external temperatures and protect the pipe structure from high temperature effects, while the waterproof layer made of polyvinyl chloride can effectively block external moisture, prevent internal corrosion of the pipe, and extend its service life.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By setting up a reinforcement mechanism, compared with the existing technology, the reinforcing steel bars in multiple fixed grooves inside the external pipe extend to both ends of the external pipe and are welded and fixed, which effectively enhances the overall rigidity. The carbon steel reinforcing rings on the surface of the reinforcing steel bars, together with multiple outer rings on the outside of the external pipe, form a stable support system. When the pipeline is squeezed by external forces, the reinforcing rings and outer rings work together to disperse the pressure and prevent the pipeline from deforming. When subjected to impact, they can buffer the impact force and ensure the integrity of the pipeline structure. This reinforcement mechanism allows the pipeline to operate stably in complex environments, such as being buried deep underground under soil pressure or being hit during construction, which greatly improves the practicality and reliability of the pipeline and extends its service life. Moreover, the steel strip layer is made of a whole piece of perforated steel strip, which improves its own strength, reduces the weight of the pipe, and enhances the tightness of the connection between each layer, improving the overall performance of the pipeline.

[0017] 2. By setting up auxiliary mechanisms, compared with existing technologies, the wear-resistant layer of polyurethane material is located on the inner wall of the built-in pipe, which can effectively resist the scouring and other wear of solid particles in the medium, greatly extending the service life of the built-in pipe. Secondly, the inner heat-resistant layer made of ceramic fiber and the outer heat-resistant layer made of glass fiber protect the inner pipe and the overall pipe structure, respectively, ensuring stable operation of the pipeline regardless of high-temperature media or external high-temperature environment. Furthermore, the waterproof layer of polyvinyl chloride is tightly attached to the outside of the outer heat-resistant layer, effectively blocking external moisture, preventing the steel strip layer from rusting and corroding, ensuring the structural strength of the pipeline, extending the overall service life of the pipeline, and enabling the pipeline to adapt to a variety of complex working conditions.

[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] The embodiments disclosed in this application are as follows: Figure 1-5 The wear-resistant perforated steel strip tube shown includes an outer tube 1, a steel strip layer 2 fixedly disposed on the inner wall of the outer tube 1, an inner tube 3 fixedly disposed on the inner wall of the steel strip layer 2, a plurality of through holes 4 opened on the surface of the steel strip layer 2, and a reinforcing mechanism disposed inside the outer tube 1.

[0026] The strengthening mechanism includes multiple fixing grooves 5 inside the external tube 1, with reinforcing steel bars 6 fixedly installed inside each fixing groove 5, and multiple reinforcing rings 7 fixedly installed on the surface of the reinforcing steel bars 6. Multiple outer rings 8 are fixedly installed on the outside of the external tube 1, and the reinforcing rings 7 are made of carbon steel.

[0027] The steel strip layer 2 is made of a whole piece of steel strip with through holes 4. The through holes 4 are distributed in an array on the steel strip layer 2. The steel strip layer 2 made in this way avoids the problem of weak connection that may exist in the braided structure, improves the strength of the steel strip layer 2 itself, and reduces the overall weight of the pipe. On the other hand, when it is processed and integrated with the inner tube 3 and the outer tube 1, it can make the materials of the inner tube 3 and the outer tube 1 better penetrate into the through holes 4, enhance the tightness of the connection between the layers, further enhance the stability and strength of the overall structure, and effectively avoid the separation between the layers due to thermal expansion and contraction caused by temperature changes.

[0028] Furthermore, the reinforcing mechanism inside the external pipe 1 greatly enhances the structural strength of the pipe. The reinforcing steel bars 6 in the multiple fixed grooves 5 extend to both ends of the external pipe 1 and are fixed by welding, which can effectively enhance the overall rigidity of the pipe. The multiple reinforcing rings 7 made of carbon steel fixed on the surface of the reinforcing steel bars 6, together with the multiple outer rings 8 fixed on the outside of the external pipe 1, further improve the pipe's resistance to pressure and deformation, ensuring that the pipe can still maintain good structural stability when subjected to external pressure or impact.

[0029] Reference Figure 2-3 As shown, the inner wall of the built-in tube 3 is provided with an auxiliary mechanism, which includes a heat-resistant layer 9 fixedly disposed on the inner wall of the built-in tube 3, and a wear-resistant layer 10 fixedly disposed on one side of the inner heat-resistant layer 9.

[0030] The inner heat-resistant layer 9 is made of ceramic fiber, and the wear-resistant layer 10 is made of polyurethane.

[0031] When the medium is transported through the pipeline, the medium first comes into contact with the wear-resistant layer 10 on the inner wall of the inner tube 3. Since the wear-resistant layer 10 is made of polyurethane, it has good wear resistance and can effectively resist the scouring of solid particles and other abrasive factors that may exist in the medium, thereby reducing the direct wear on the inner tube 3 and extending the service life of the inner tube 3.

[0032] Furthermore, during the medium transportation process, if the medium temperature is high or the ambient temperature changes significantly, the inner heat-resistant layer 9 and the outer heat-resistant layer 11 come into play. The inner heat-resistant layer 9 is made of ceramic fiber, and the outer heat-resistant layer 11 is made of glass fiber. Both of them have good heat resistance. The inner heat-resistant layer 9 can prevent the high-temperature medium from causing thermal damage to the inner pipe, while the outer heat-resistant layer 11 can resist the impact of the high-temperature environment on the overall structure of the pipeline, ensuring that the pipeline can operate stably under different temperature conditions.

[0033] Reference Figure 4-5 As shown, an external heat-resistant layer 11 is fixedly provided on the surface of the external tube 1, and a waterproof layer 12 is fixedly provided on one side of the external heat-resistant layer 11. The external heat-resistant layer 11 is made of fiberglass, and the waterproof layer 12 is made of polyvinyl chloride.

[0034] Through holes 4 are arranged in an array on the surface of steel strip layer 2. The two ends of reinforcing steel bars 6 extend to the two ends of external tube 1 respectively, and the reinforcing steel bars 6 and the ends of external tube 1 are fixed by welding.

[0035] During pipeline use, external moisture may damage the pipeline. At this time, the waterproof layer 12 plays a key role. The waterproof layer 12 is made of polyvinyl chloride and is tightly attached to one side of the outer heat-resistant layer 11. It can effectively block the intrusion of external moisture and prevent moisture from penetrating into the pipeline and causing the steel strip layer 2 to rust and corrode, thereby ensuring the structural strength and service life of the pipeline.

[0036] Working principle of this utility model:

[0037] This utility model is a wear-resistant perforated steel strip pipe. When the device is in use, when there is a fluid medium that needs to be transported through the pipeline, the medium first comes into contact with the wear-resistant layer 10 on the inner wall of the inner tube 3. Since the wear-resistant layer 10 is made of polyurethane, it has good wear resistance and can effectively resist the scouring of solid particles and other wear factors that may exist in the medium, reducing the direct wear on the inner tube 3, thereby extending the service life of the inner tube 3.

[0038] Furthermore, during the medium transportation process, if the medium temperature is high or the ambient temperature changes significantly, the inner heat-resistant layer 9 and the outer heat-resistant layer 11 come into play. The inner heat-resistant layer 9 is made of ceramic fiber, and the outer heat-resistant layer 11 is made of glass fiber. Both of them have good heat resistance. The inner heat-resistant layer 9 can prevent the high-temperature medium from causing thermal damage to the inner pipe, while the outer heat-resistant layer 11 can resist the influence of the high-temperature environment on the overall structure of the pipeline, ensuring that the pipeline can operate stably under different temperature conditions.

[0039] During the use of the pipeline, external moisture may damage the pipeline. At this time, the waterproof layer 12 plays a key role. The waterproof layer 12 is made of polyvinyl chloride and is tightly attached to one side of the outer heat-resistant layer 11. It can effectively block the intrusion of external moisture and prevent moisture from penetrating into the pipeline and causing the steel strip layer 2 to rust and corrode, thereby ensuring the structural strength and service life of the pipeline.

[0040] The steel strip layer 2 is made of a whole piece of steel strip with through holes 4. The through holes 4 are distributed in an array on the steel strip layer 2. The steel strip layer 2 made in this way avoids the problem of weak connection that may exist in the braided structure, improves the strength of the steel strip layer 2 itself, and reduces the overall weight of the pipe. On the other hand, when it is processed and integrated with the inner tube 3 and the outer tube 1, it can make the materials of the inner tube 3 and the outer tube 1 better penetrate into the through holes 4, enhance the tightness of the connection between the layers, further enhance the stability and strength of the overall structure, and effectively avoid the separation between the layers due to thermal expansion and contraction caused by temperature changes.

[0041] Furthermore, the reinforcing mechanism inside the external pipe 1 greatly enhances the structural strength of the pipe. The reinforcing steel bars 6 in the multiple fixed grooves 5 extend to both ends of the external pipe 1 and are fixed by welding, which can effectively enhance the overall rigidity of the pipe. The multiple reinforcing rings 7 made of carbon steel fixed on the surface of the reinforcing steel bars 6, together with the multiple outer rings 8 fixed on the outside of the external pipe 1, further improve the pipe's resistance to pressure and deformation, ensuring that the pipe can still maintain good structural stability when subjected to external pressure or impact.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
