Description

Technical Field

[0001] This utility model relates to the field of municipal sewage discharge, and in particular to a solid waste modified PVC alloy sewage pipe. Background Technology

[0002] In the field of municipal sewage discharge, traditional sewage pipes often face problems such as insufficient structural stability and poor impact resistance. Existing pipes mostly use a single material or a simple structural design. During long-term sewage discharge, fluid impact easily leads to accelerated wear of the pipe's inner wall, and local turbulence can also cause energy loss and pipe vibration, affecting structural stability and shortening service life. Simultaneously, under external impact or compression, traditional pipes lack effective buffering structures, making them prone to cracks, deformation, and other damage, increasing maintenance costs and safety hazards. Furthermore, some pipes have poor corrosion resistance and are prone to aging and failure under the corrosive effects of chemicals in sewage. Therefore, there is an urgent need to develop a new type of sewage pipe that is structurally stable, highly impact-resistant, and durable to meet the actual needs of municipal sewage discharge.

[0003] While existing technologies can achieve a certain level of sewage discharge, they suffer from several drawbacks: they lack a dispersion structure to address fluid impacts and an effective shock-absorbing design. In light of this, we propose a solid waste modified PVC alloy sewage pipe that solves these problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a solid waste modified PVC alloy sewage pipe.

[0005] The technical solution of this utility model is as follows: a solid waste modified PVC alloy sewage pipe, including a pipe body and a biomimetic corrugated layer. The inner wall of the pipe body is provided with an inner layer, and a biomimetic corrugated layer is provided on one side of the inner layer. A plurality of troughs arranged in a circular array are provided on one side of the biomimetic corrugated layer, and a crest is provided at one end of the trough. The width of the trough gradually decreases from the width of the crest. The biomimetic corrugated layer can form a gradual shape similar to natural waves, thereby enhancing structural stability.

[0006] When using one of the solid waste modified PVC alloy sewage pipes in this solution, align the flanges of the two sewage pipes to be connected, ensuring that the bolt holes on the flanges correspond one-to-one. Use appropriate bolts and nuts, and tighten the bolts on the flanges evenly. After the sewage pipe is installed, it can be put into use for sewage discharge. During the discharge process, the gradual shape of the biomimetic corrugated layer can disperse the fluid impact pressure and reduce wear on the inner wall of the pipe. The gentle curvature formed by the 60-degree radius of curvature of the wave crest can reduce the resistance when the fluid flows through, avoid energy loss and pipe vibration caused by local turbulence, and ensure smooth sewage discharge. The impact-resistant layer of the pipe body has multiple circularly arrayed slots, the cross-section of which is an acute triangle with the acute angle pointing towards the center of the pipe. When the pipe is subjected to external impact or compression, the slots can absorb the impact force through deformation. The acute triangle structure uses the stability of triangles to disperse the impact force, and the shape of being wider on the outside and narrower on the inside can guide the force to be transmitted to the center of the pipe for buffering, effectively reducing the risk of pipe damage and enabling the pipe to adapt to external pressure changes within a certain range.

[0007] Preferably, an impact-resistant layer is provided on the other side of the inner layer, and the impact-resistant layer has a plurality of slots arranged in a circular array, which reduces the overall weight.

[0008] Preferably, the impact-resistant layer has a corrosion-resistant layer on one side and a protective layer on the other side.

[0009] Preferably, flanges are fixedly connected to both ends of the pipe body, which facilitates the docking and installation of pipes.

[0010] Preferably, the cross-section of the slot is an acute triangle, with the acute angles of the triangle pointing to the midpoint of the tube. The slot is wider at the outside and narrower at the inside, effectively buffering the impact force.

[0011] Preferably, the radius of curvature of the wave crest is 60 degrees, and the curvature of the wave crest is relatively gentle.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] I. This utility model ensures excellent structural stability through the scientific design of a biomimetic corrugated layer. The biomimetic corrugated layer has multiple troughs and crests arranged in a circular array, with the width of the troughs gradually decreasing towards the crests. This gradual change in shape effectively disperses the fluid impact pressure during sewage discharge, reducing wear on the inner wall of the pipe. At the same time, the 60-degree radius of curvature of the crests forms a gentle curvature, which reduces the resistance when the fluid flows through, avoids energy loss and pipe vibration caused by local turbulence, and ensures that the pipe maintains structural stability during long-term use, guaranteeing smooth sewage discharge.

[0014] II. Building upon the first beneficial effect, the special structure of the impact-resistant layer further enhances the pipeline's impact resistance. The impact-resistant layer contains multiple circularly arrayed slots, each with an acute-angled triangular cross-section pointing towards the pipeline's center. When the pipeline is subjected to external impact or compression, the slots absorb the impact force through deformation. The acute-angled triangular structure disperses the impact force through the stability of a triangle, and its wider outer and narrower inner shape guides the force towards the pipeline's center for buffering, effectively reducing the risk of pipeline damage. This allows the pipeline to adapt to a certain range of external pressure changes, improving its durability under complex operating conditions.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Please see Figures 1-4 As shown, this embodiment is a solid waste modified PVC alloy sewage pipe, including a pipe body 1 and a biomimetic corrugated layer 6. The inner wall of the pipe body 1 is provided with an inner layer 7, and a biomimetic corrugated layer 6 is provided on one side of the inner layer 7. A plurality of troughs 5 arranged in a circular array are provided on one side of the biomimetic corrugated layer 6, and a crest 4 is provided at one end of the trough 5. The width of the trough 5 gradually decreases from the width of the crest 4. In use, the gradual change shape of the biomimetic corrugated layer 6 can disperse the fluid impact pressure, reduce the wear of the inner wall of the pipe, and improve the overall structural stability. In the crest 4 area, which bears the maximum bending stress, a PVC alloy layer reinforced with short-cut fibers is used. In the trough 5 area, which requires flexibility, a solid waste modified PVC alloy layer with better toughness and elastic recovery is used.

[0028] Example 2

[0029] Please see Figures 1-4 As shown, this embodiment further includes, based on embodiment 1, an impact-resistant layer 8 on the other side of the inner layer 7. The impact-resistant layer 8 contains a plurality of circumferentially arrayed slots 3. In use, the slots 3 can absorb external impact forces through deformation, reducing the risk of damage to the pipe when it is collided or squeezed, while also reducing the weight of the pipe for easy installation.

[0030] The impact-resistant layer 8 has a corrosion-resistant layer 9 on one side and a protective layer 10 on the other side. During use, the corrosion-resistant layer 9 can resist the erosion of chemicals in sewage, while the protective layer 10 further isolates the pipeline from the influence of the external environment and extends its service life.

[0031] Both ends of the pipe body 1 are fixedly connected to flanges 2. During use, the flanges 2 can quickly achieve a sealed connection between the pipes, ensuring the firmness and leak-proof performance of the connection.

[0032] The cross-section of the hollow groove 3 is an acute triangle, with the acute angles of the triangle pointing towards the center of the pipe. In use, the acute triangle structure utilizes the stability of the triangle to disperse the impact force, and the shape of being wider on the outside and narrower on the inside can guide the force to be transmitted and buffered towards the center of the pipe, thus enhancing the impact resistance.

[0033] The radius of curvature of wave crest 4 is degrees. When in use, the gentle curvature can reduce the resistance of fluid flow and avoid energy loss and pipe vibration caused by local turbulence.

[0034] Instructions for use: When using this device, align the flanges 2 of the two sewage pipes to be connected, ensuring that the bolt holes on the flanges 2 correspond one-to-one. Use appropriate bolts and nuts to tighten the bolts on the flanges 2 evenly. After the sewage pipes are installed, they can be put into use for sewage discharge. During the discharge process, the gradual shape of the biomimetic corrugated layer 6 can disperse the fluid impact pressure and reduce wear on the inner wall of the pipe. The gentle curvature formed by the 4-degree radius of curvature of the wave crest can reduce the resistance when the fluid flows through, avoid energy loss and pipe vibration caused by local turbulence, and ensure smooth sewage discharge. The impact-resistant layer 8 of the pipe body 1 has multiple circularly arrayed slots 3. The cross-section of the slots 3 is an acute triangle with the acute angle pointing towards the center of the pipe. When the pipe is subjected to external impact or compression, the slots 3 can absorb the impact force through deformation. The acute triangle structure uses the stability of triangles to disperse the impact force. The shape of being wider on the outside and narrower on the inside can guide the force to be transmitted to the center of the pipe for buffering, effectively reducing the risk of pipe damage and enabling the pipe to adapt to external pressure changes within a certain range.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
