Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a phosphogypsum-based self-healing antibacterial water supply pipe. Background Technology

[0002] The core material of phosphogypsum-based water supply pipes is mainly derived from phosphogypsum, a large-scale industrial solid waste generated during the wet-process phosphoric acid production process. Approximately 4-5 tons of phosphogypsum are produced for every ton of phosphoric acid produced. Transforming phosphogypsum from waste into a valuable resource solves the problems of its storage, land occupation, and environmental pollution. Pipes made with phosphogypsum as a base are environmentally friendly.

[0003] The water supply pipeline has a large structure and is installed by flange connection. However, the assembly holes inside the flange are difficult to align during the connection process, and misalignment may occur during installation. This makes positioning difficult and increases the time and complexity of installation. To address these issues, we propose a phosphogypsum-based self-healing antibacterial water supply pipe. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a phosphogypsum-based self-healing antibacterial water supply pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a phosphogypsum-based self-healing antibacterial water supply pipe, comprising a phosphogypsum water supply pipe body, flange one, a connecting block, a connecting seat, and flange two. Flange one and flange two are respectively provided at opposite ends of the phosphogypsum water supply pipe body. A connecting seat arranged in a ring array is provided on the outer wall of one side of flange one. A connecting block arranged in a ring array is provided at one end of flange two. Assembly holes arranged in a ring array and correspondingly distributed are provided inside flange one and flange two. A connecting groove and an installation hole are provided inside the connecting seat. A support ring is provided on the inner wall of the installation hole. A spring one is provided at the lower end of the support ring. A pressure ball is provided at the lower end of the spring. A positioning hole is provided inside the connecting block.

[0006] Preferably, both flange one and flange two have corresponding annular grooves at opposite ends, and a sealing ring is disposed inside the annular groove. When flange one and flange two are mated, the sealing ring is placed inside the annular groove, thereby improving the sealing performance when flange one and flange two are mated.

[0007] Preferably, one end of the flange has a groove, and one end of the second flange is rotatably mounted with balls arranged in a circular array and rolling inside the groove. The balls roll inside the groove, and when the first flange and the second flange are mated, the rotational support provided by the balls facilitates pipe angle adjustment.

[0008] Preferably, the phosphogypsum water supply pipe body includes an inner pipe, an outer pipe, and a repair layer. The inner and outer pipes are made of phosphogypsum-based pipe material, and the repair layer is filled with alkali-resistant bacterial spores and nutrients.

[0009] Preferably, the upper end of the pressure ball is provided with a guide rod that is slidably inserted into the support ring, and the upper end of the guide rod is provided with a limit ring. The guide rod passes through the support ring easily through the limit ring, guiding the telescopic spring and preventing the spring from deviating.

[0010] Preferably, one end of the docking block is provided with a second chamfer, and the inner wall of the slot is provided with a first chamfer. When the docking block docks with the slot in the docking seat through the first chamfer, the second chamfer reduces resistance and friction, improving docking smoothness.

[0011] Preferably, a guide plate is provided at one end of the docking seat, a second spring is provided at the lower end of the guide plate, and a pressure block is provided at the lower end of the second spring. During use, the guide plate supports the second spring, and the pressure block elastically presses against the bolt, thus holding the bolt installed inside the assembly hole and preventing it from loosening.

[0012] Preferably, the inner wall of the pressure block is provided with an anti-slip pad, and the upper end of the pressure block is provided with a guide rod two located inside the second spring and slidably inserted into the guide plate. The upper end of the guide rod two is provided with a pull ring. The anti-slip pad improves the tightness of the threaded contact with the outer wall of the bolt, and the guide rod two slides inside the second spring and the guide plate to guide the second spring and prevent it from shifting during the extension and contraction of the second spring. The pull ring makes it easy to apply a pulling force to the guide rod two.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The main body of the phosphogypsum water supply pipe of this utility model is connected by flanges. During the flange connection process, the connecting block and the connecting seat are connected. During the connection process, the connecting block inserted into the slot squeezes the elastic support ball inside the upper end of the slot. The spring is compressed and causes the connecting block to pass through the ball. After the ball is connected with the positioning hole, the elastic support force of the spring pushes the ball into the positioning hole. This ensures that the main body of the phosphogypsum water supply pipe is positioned during installation, and the assembly holes are effectively connected. This avoids the problem of misalignment of the assembly holes during bolt assembly, which affects the installation. This makes the assembly process of the phosphogypsum water supply pipe body time-saving and convenient. Attached Figure Description

[0021] 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.

[0022] like Figures 1-5 As shown, this utility model proposes a phosphogypsum-based self-healing antibacterial water supply pipe, which includes a phosphogypsum water supply pipe body 1, flange 1 5, connecting block 9, connecting seat 12, and flange 29. Flange 1 5 and flange 29 are respectively provided at opposite ends of the phosphogypsum water supply pipe body 1. Connecting seats 12 are arranged in a ring array on one side of the outer wall of flange 1 5. Connecting blocks 9 are arranged in a ring array at one end of flange 29. Assembly holes 6 are arranged in a ring array and correspondingly distributed inside flange 1 5 and flange 29. Connecting seat 12 is provided with a communicating groove 13 and mounting hole 20 inside. Support ring 18 is provided on the inner wall of mounting hole 20. Spring 16 is provided at the lower end of support ring 18. Pressure ball 15 is provided at the lower end of spring 16. Positioning hole 28 is provided inside connecting block 9.

[0023] Flange 1 5 and Flange 2 29 are each provided with a corresponding annular groove 8 at one end, and a sealing ring 10 is provided inside the annular groove 8;

[0024] Flange 1 has a groove 7 at one end, and flange 29 has balls 11 arranged in a ring array and rolled inside the groove 7 at one end.

[0025] The main body 1 of the phosphogypsum water supply pipe includes an inner pipe 2, an outer pipe 4, and a repair layer 3;

[0026] The upper end of the pressure bead 15 is provided with a guide rod 17 that is slidably inserted into the support ring 18, and the upper end of the guide rod 17 is provided with a limit ring 19.

[0027] One end of the mating block 9 is provided with chamfer 27, and the inner wall of the slot 13 is provided with chamfer 14;

[0028] A guide plate 22 is provided at one end of the docking seat 12, a second spring 23 is provided at the lower end of the guide plate 22, and a pressure block 26 is provided at the lower end of the second spring 23;

[0029] The inner wall of the pressure block 26 is provided with an anti-slip pad 25. The upper end of the pressure block 26 is provided with a guide rod 24 located inside the second spring 23 and slidably inserted into the guide plate 22. The upper end of the guide rod 24 is provided with a pull ring 21.

[0030] Based on the implementation steps of Example 1: Before flange 15 and flange 29 are connected, the sealing ring 10 is pre-embedded in the annular groove 8. This design ensures that when the two flange end faces are closed, the sealing ring 10 is uniformly squeezed to form a radial seal. When the angle of the phosphogypsum water supply pipe body 1 is finely adjusted, the ball 11 of flange 29 is embedded in the groove 7 of flange 15. The ball 11 rolls freely in the groove 7, providing rotational freedom. When the phosphogypsum water supply pipe body 1 rotates, the resistance is reduced, and the problem of installation angle deviation caused by the weight of the large pipe is overcome.

[0031] Align the mating block 9 of flange 29 with the mating seat 12 of flange 15 and insert it. The chamfer 27 at the front end of the mating block 9 contacts the chamfer 14 of the inner groove 13 of the mating seat 12, and the frictional resistance is reduced by the guide of the chamfer.

[0032] During the insertion of the docking block 9, the bottom of the block presses the pressure ball 15 in the slot 13. The pressure ball 15 is forced to move upward, compressing the spring 16 and driving the guide rod 17 to slide in the support ring 18. When the positioning hole 28 of the docking block 9 reaches directly below the pressure ball 15, the spring 16 releases its elastic force, pushing the pressure ball 15 into the positioning hole 28 to achieve mechanical locking. The elastic pressure ball 15 forms an instantaneous self-locking mechanism, which automatically aligns all the assembly holes 6, completely eliminating the time-consuming process of manually calibrating the hole positions.

[0033] Insert the bolt into the aligned assembly hole 6 and tighten the nut. During the bolt installation process, lift the pressure block 26 inside the docking seat 12. After the bolt is fixed, the elastic force of the second spring 23 pushes the pressure block 26 down. The anti-slip pad 25 on the inner wall of the pressure block 26 is in close contact with the bolt thread. At the same time, the second spring 23 is compressed and stores energy. After releasing the pressure block 26, the second spring 23 pushes the pressure block 26 to continuously tighten the bolt, generating constant pressure to suppress bolt vibration and loosening.

[0034] During pipe manufacturing, specific alkali-resistant bacterial spores (such as Bacillus pasteurellii) and their required nutrients (such as calcium lactate and yeast extract) are encapsulated in a protective carrier (such as porous ceramsite, expanded clay, or biodegradable polymer microcapsules) and uniformly incorporated into the phosphogypsum-based composite material. When microcracks appear in the pipe, moisture and air seep in, and the moisture activates the dormant bacterial spores. The bacteria metabolize nutrients (especially calcium sources), producing carbonate ions. In an alkaline environment (provided by cement / gypsum hydration products), carbonate ions combine with calcium ions to form calcium carbonate crystal precipitates. The main body of the pipe uses phosphogypsum solid waste as the primary raw material, reducing production costs and minimizing solid waste storage pollution. The calcium carbonate crystals gradually fill and seal the cracks, restoring the structural integrity and airtightness, preventing leakage, and blocking the intrusion of harmful substances.

[0035] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
