[0022] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.

[0025] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0026] The specific embodiments of the present disclosure are described below in conjunction with the accompanying drawings.

[0027] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0028] In this article, "first", "second", etc. are only used to distinguish each other, and do not indicate the importance and order, or the premise of each other's existence.

[0029] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0030] In order to solve the problems of complicated manufacturing process and high manufacturing cost of the black stone composite material pipe in the prior art, the present invention provides a method for manufacturing the black stone composite material pipe, see Figure 1 The method for making the black stone composite material tube disclosed in the present invention comprises the following steps: S102: Processing the basalt raw material into basalt powder, wherein the basalt raw material contains 47% to 52% of silicon dioxide and 12% to 15% of aluminum oxide; S104: melting the black stone powder to form a black stone solution and drawing the solution into a black stone fiber bundle; S106: After the black stone fiber bundle 3 is impregnated with the substrate, and the surface felt 8 is applied to the outer side of the black stone fiber bundle 3, and the input pipe is heat-set in sections within the mold to form a black stone composite material tube 9; S108: After the basalt composite material tube is cooled, the basalt composite material tube is pulled out and cut.

[0031] It should be noted that the basalt raw material referred to in this disclosure refers to the block basalt formed by volcanic eruptions in the mining area. Due to the different proportions of each component in the basalt, the characteristics presented are also different. The basalt raw material selected in this disclosure contains 47% to 52% silicon dioxide and 12% to 15% aluminum oxide, and the remaining elements can be: calcium oxide, iron oxide, etc. Compared with basalt raw materials of other components, the basalt composite material pipe processed by using this basalt raw material with a certain proportion has the advantages of corrosion resistance and high strength.

[0032] Among them, the specific steps of processing the black stone raw material into black stone powder in step S102 include: The basalt raw material is processed into basalt particles of a preset mesh size, and then the basalt particles are crushed into basalt powder by a crushing mechanism. It should be noted that the preset mesh size range of the basalt particles is: 600 mesh to 800 mesh.

[0033] After the basalt raw material is processed into basalt powder in step S102, the manufacturing method enters step S104, that is, the basalt powder is melted to form a basalt solution and drawn into a basalt fiber bundle 3. In detail, S104 includes the following steps: S1040: Add the black stone powder into the heating container. Adding the black stone powder into the heating container can effectively speed up the melting speed of the black stone. S1041: Heat the basalt powder in the heating container to melt it and form a basalt solution.

[0034] It should be noted that the heating temperature and pressure in step S1041 are controlled to heat the black stone powder into a black stone solution. For example, in one embodiment, the heating temperature is 1500° C. and the pressure can be 1 GPa: S1042: Processing the heated basalt solution into basalt fiber yarns.

[0035] Specifically, see Figure 3 A plurality of leakage holes are provided at the bottom of the heating container, and the diameter of the leakage holes depends on the diameter requirement of the basalt fiber. In one embodiment, the diameter of the leakage holes is between 5 and 10 μm.

[0036] The basalt solution in the heating container flows out from the leak hole under its own gravity, and after flowing out, it is cooled to form a flexible filament, that is, basalt fiber. The diameter of the basalt fiber depends on the size of the leak hole. For example, in the embodiment described above, the diameter of the basalt fiber ranges from 5 to 10 μm. Of course, the diameter of the basalt fiber can be determined according to actual product requirements, and this is only an exemplary description.

[0037] S1043: The black stone fiber strands are twisted to form black stone fiber bundles.

[0038] Specifically, in one embodiment, the plying process step of the present disclosure is completed by a plying mechanism, see Figure 4 The stranding mechanism 5 includes a first circular threading plate 51, a second circular threading plate 52, a third circular threading plate 53 and a wire harness 54 which are arranged at intervals and parallel to each other, wherein the first circular threading plate 51, the second circular threading plate 52 and the third circular threading plate 53 are coaxially arranged, and the first circular threading plate 51, the second circular threading plate 52 and the third circular threading plate 53 can rotate around the axis of the stranding mechanism 5, and at the same time, the first circular threading plate 51, the second circular threading plate 52 and the third circular threading plate 53 are evenly provided with a plurality of threading holes in the circumferential direction.

[0039] During the plying process, a plurality of black stone fiber strands 2 pass through the threading holes of the third circular threading plate 53 , the second circular threading plate 52 and the first circular threading plate 51 in sequence, and one end of the black stone fiber strands 2 is wound around the drum 4 .

[0040] During the operation of the stranding mechanism 5, since the diameters of the third circular threading plate 53, the second circular threading plate 52 and the first circular threading plate 51 decrease gradually, under the action of the third circular threading plate 53, the second circular threading plate 52 and the first circular threading plate 51, multiple basalt fiber filaments 2 are gathered together.

[0041] At the position between the first circular threading plate 51 and the wire bundle 54, a wetting agent will be applied to the basalt fiber filaments 2 that are about to converge, so as to prevent the basalt fiber filaments 2 from sticking together after high-temperature contact. At the same time, it is also beneficial for the subsequent coupling of the basalt fiber bundle 3 with the substrate, acting as a bridge for the bonding of the basalt fiber bundle 3 with the substrate.

[0042] At the same time, the third circular threading plate 53, the second circular threading plate 52 and the first circular threading plate 51 drive the black stone fiber filaments 2 to rotate relative to the axis of the plying mechanism, so that the black stone fiber filaments 2 are intertwined to form a black stone fiber bundle 3. Then, the black stone fiber bundle 3 passes through the wire bundle 54 to straighten the black stone fiber bundle 3. At the same time, the drum 4 keeps rotating, so that the black stone fiber bundle 3 just formed is wound on the drum 4, and finally the drum 4 with the black stone fiber bundle 3 is placed on the creel.

[0043] In step S106, the basalt fiber bundle is impregnated with the base material, and a surface felt is applied to the outside of the basalt fiber bundle, and then the basalt fiber bundle is input into a pipe fitting mold for segmented heat curing to form a basalt composite material pipe. This step is specifically as follows: The basalt fiber bundles are pulled out by multiple rollers placed on the creel. Figure 5 When passing through the impregnation tank, the surface of these basalt fiber bundles infects the substrate, and then a surface felt 8 is arranged on the surface of the basalt fiber bundle 3 to enhance the strength of the basalt composite material tube 9. These basalt fiber bundles then enter the thermosetting mold to form a basalt composite material tube.

[0044] In step S108, the basalt composite material tube in the thermosetting mold is formed, and after cooling, the basalt composite material tube is taken out by a taking mechanism and cut, and finally a usable finished tube is formed.

[0045] The manufacturing method of the basalt composite material tube provided by the present disclosure has a simple process and can ensure the strength requirement of the basalt composite material tube 9.

[0046] In one embodiment of the present disclosure, the step of heat-curing the input pipe fitting mold to form a basalt composite material pipe includes step S202: S202: The pipe is input into a pipe fitting mold and subjected to a stepwise heat curing treatment at a first working temperature, a second working temperature, and a third working temperature in an increasing temperature gradient in sequence to form a basalt composite material pipe.

[0047] In the actual processing process, the basalt fiber bundle 3 needs to be heated gradually so that the basalt fiber bundle 3 is completely bonded to the substrate to form a basalt composite material tube 9 .

[0048] Specifically, in one embodiment of the present disclosure, the first working temperature is 90° C., the second working temperature is 120° C., and the third working temperature is 150° C. After being heated at 90° C., 120° C., and 150° C., the basalt fiber bundle 3 is completely bonded to the substrate and becomes a basalt composite material tube 9 after being cured.

[0049] After the above-mentioned gradient heating, the basalt fiber bundle 3 can be fused with the substrate, thereby improving the overall strength of the basalt composite material tube 9.

[0050] In one embodiment of the present disclosure, the step of heat-curing the input pipe fitting mold to form the basalt composite material pipe 9 includes step S302: S302: After entering the pipe fitting mold, the pipe is subjected to segmented heat curing treatment under a preset working pressure within a preset time to be formed into a basalt composite material pipe 9, wherein the preset working pressure is 10Mpa to 15Mpa, and the preset time is 20s to 50s.

[0051] In the actual processing, Figure 2 As shown, in the process of gradient heating the basalt fiber bundle 3, the basalt fiber bundle 3 needs to be pressurized and the processing time of the basalt fiber bundle 3 needs to be controlled so that the basalt composite material tube 9 reaches a preset strength.

[0052] In one embodiment of the present disclosure, drawing the black stone fiber bundle 3 comprises the following steps: S402: First, a black stone fiber filament 2 is drawn out from the black stone solution; S404: Winding and drawing a plurality of basalt fiber filaments 2 to form a basalt fiber bundle 3.

[0053] As mentioned above, after heating, the basalt powder forms a basalt solution, and the basalt solution forms basalt fiber filaments 2 under the action of the heating container 1. The diameter of the basalt fiber filaments 2 is in the range of 5 μm to 10 μm.

[0054] After the basalt fiber strands 2 are coated with the wetting agent, they are drawn through the roller 4 to form a basalt fiber bundle 3. For example, the basalt solution is heated in the container 1 to form 100 basalt fiber strands 2, and after the basalt fiber strands 2 are stained with the wetting agent, they are drawn by the roller 4 to form a basalt fiber bundle 3.

[0055] Since the diameter of a single basalt fiber filament 2 is relatively thin, a single basalt fiber bundle 3 formed by a plurality of basalt fiber filaments 2 has a higher strength and a more stable structure.

[0056] In one embodiment of the present disclosure, the substrate includes basalt powder and organic resin, and the ratio of basalt fiber to basalt powder and organic resin is 3:1:1.

[0057] In actual applications, considering the manufacturing cost, the organic resin is mixed with the basalt powder to form a base material together, so that the ratio of basalt fiber to basalt powder and organic resin is 3:1:1. This setting can reduce the proportion of the basalt fiber bundle 3, that is, using basalt powder to replace part of the basalt fiber bundle 3, thereby reducing the manufacturing cost of the basalt composite material tube 9, while ensuring the strength of the basalt composite material tube 9.

[0058] In addition, the organic resin mentioned above can be epoxy resin, unsaturated resin, isophthalic resin or phenolic resin. In one embodiment provided by the present disclosure, the organic resin used for the substrate is an unsaturated resin, and the unsaturated resin is added to the basalt fiber bundle to ensure the corrosion resistance, strength and water resistance of the basalt composite material pipe.

[0059] In a second aspect, the present disclosure provides a manufacturing device for a basalt composite material tube 9 , which includes: a heating container 1 , a stranding mechanism 5 , an impregnation tank 6 , a thermosetting mechanism 7 and a taking-up mechanism 10 .

[0060] Specifically, a micron-sized leak hole is provided at the bottom of the heating container 1, and the heating container 1 is configured to form the black stone fiber filament 2 through the leak hole after the heat melting; The plying mechanism 5 is configured to wind and draw a plurality of black stone fiber strands 2 to form a black stone fiber bundle 3; A base material is provided in the dyeing tank 6, and is configured to dye the black stone fiber bundle 3 passing through the dyeing tank with the base material; The heat-setting mechanism 7 is configured to heat and cure the basalt fiber bundle 3 impregnated with the substrate into a basalt composite material tube 9; The taking-out mechanism 10 is configured to pull the black stone composite material tube 9 out of the heat-setting mechanism 7 .

[0061] like Figure 3 As shown, the upper space of the heating container 1 is used to place basalt powder, which is then heated by the heating container 1. As the basalt powder is heated, a basalt solution is formed. The basalt solution flows out along the leakage holes set at the bottom of the heating container 1 under the action of its own gravity, forming multiple basalt fiber filaments 2.

[0062] Then, the plurality of black stone fiber strands 2 are formed into a single black stone fiber bundle 3 under the action of the plying mechanism 5. Figure 4 The stranding mechanism 5 includes a first circular threading plate 51, a second circular threading plate 52, a third circular threading plate 53 and a wire harness 54 which are arranged at intervals and parallel to each other, wherein the first circular threading plate 51, the second circular threading plate 52 and the third circular threading plate 53 are coaxially arranged, and the first circular threading plate 51, the second circular threading plate 52 and the third circular threading plate 53 can rotate around the axis of the stranding mechanism 5, and at the same time, the first circular threading plate 51, the second circular threading plate 52 and the third circular threading plate 53 are evenly provided with a plurality of threading holes in the circumferential direction.

[0063] During the plying process, multiple basalt fiber strands 2 pass through the threading holes of the third circular threading plate 53, the second circular threading plate 52 and the first circular threading plate 51 in turn, and one end of these basalt fiber strands 2 is fixed to one end of the basalt fiber strand 2 serving as the busbar, and are finally wound around the drum 4.

[0064] During the operation of the stranding mechanism 5, since the diameters of the third circular threading plate 53, the second circular threading plate 52 and the first circular threading plate 51 decrease gradually, under the action of the third circular threading plate 53, the second circular threading plate 52 and the first circular threading plate 51, multiple basalt fiber filaments 2 are gathered together.

[0065] At the position between the first circular threading plate 51 and the wire bundle 54, a wetting agent will be applied to the basalt fiber filaments 2 that are about to converge, so as to prevent the basalt fiber filaments 2 from sticking together after high-temperature contact. At the same time, it is also beneficial for the subsequent coupling of the basalt fiber bundle 3 with the substrate, acting as a bridge for the bonding of the basalt fiber bundle 3 with the substrate.

[0066] At the same time, the third circular threading plate 53, the second circular threading plate 52 and the first circular threading plate 51 drive the black stone fiber filaments 2 to rotate relative to the axis of the plying mechanism, so that the black stone fiber filaments 2 are intertwined to form a black stone fiber bundle 3. Then, the black stone fiber bundle 3 passes through the wire bundle 54 to straighten the black stone fiber bundle 3. At the same time, the drum 4 keeps rotating, so that the black stone fiber bundle 3 just formed is wound on the drum 4, and finally the drum with the black stone fiber bundle wound is placed on the creel.

[0067] Then, if Figure 5 As shown, multiple basalt fiber bundles 3 are drawn out from the roller on the yarn rack and are impregnated with the substrate through the impregnation tank 6. Specifically, perforators are provided on both sides of the impregnation tank, and multiple basalt fiber bundles 3 are suspended directly above the impregnation tank under the action of the perforators. Due to the influence of the deadweight of the basalt fiber bundles 3, the basalt fiber bundles 3 located in the middle of the impregnation tank will droop and fall into the inside of the impregnation tank, and then contact the substrate inside the impregnation tank, thereby realizing the process of impregnating the basalt fiber bundles 3 with the substrate.

[0068] Subsequently, the basalt fiber bundle 3 infecting the substrate is ready to enter the heat-setting mechanism 7 . During this process, the surface felt laying device arranged on the heat-setting mechanism 7 will lay the surface felt 8 on the surface of the basalt fiber bundle 3 .

[0069] After the surface felt 8 is applied to the surface of the basalt fiber bundle 3 , the basalt fiber bundle 3 enters the heat-setting mechanism 7 , and after gradient heating by the heat-setting mechanism 7 , the basalt fiber bundle 3 is heat-cured to become a basalt composite material tube 9 .

[0070] After the basalt composite material tube 9 is cooled, the taking mechanism 10 extracts the basalt composite material tube 9 from the heat-setting mechanism 7 and cuts it so that the length of the basalt composite material tube 9 meets the use requirements.

[0071] The manufacturing device of the basalt composite material tube 9 provided in the present disclosure has a simple structure, can realize the whole set of processing from basalt raw material to basalt composite material tube 9, and has a high level of automation.

[0072] In one embodiment of the present disclosure, the thermosetting mechanism 7 is provided with a first annular heating chamber 71, a second annular heating chamber 72 and a third annular heating chamber 73 in sequence along the axial direction, wherein the first annular heating chamber 71 is configured to store 90°C heating oil, the second annular heating chamber 72 is configured to store 120°C heating oil, and the third annular heating chamber 73 is configured to store 150°C heating oil.

[0073] like Figure 6 As shown, the heat setting mechanism 7 is provided with a first annular heating chamber 71, a second annular heating chamber 72 and a third annular heating chamber 73 along the axial direction. During use, hot oils of different temperatures are introduced into the first annular heating chamber 71, the second annular heating chamber 72 and the third annular heating chamber 73 to achieve gradient heating of the black stone fiber bundle 3.

[0074] In one embodiment of the present disclosure, a tube core mold 74 is disposed at the axis of the heat setting mechanism 7 , and the tube core mold 74 is configured to support the black stone fiber bundle 3 until it is heated and cured.

[0075] Continue to refer Figure 6 A tube core mold 74 is provided at the axis of the heat setting mechanism 7. When the basalt fiber bundle 3 enters the heat setting mechanism 7, multiple basalt fiber bundles 3 are attached around the tube core mold 74. When the basalt fiber bundles 3 are heated, they will be cured into the shape of a tube along the tube core mold 74.

[0076] In one embodiment of the present disclosure, the retrieval mechanism 10 includes a first pulling member 101 and a second pulling member 102. The first pulling member 101 and the second pulling member 102 are both configured to selectively clamp or loosen the black stone composite material tube 9, and pull the black stone composite material tube 9 out of the thermosetting mechanism 7 under the drive of the mobile device.

[0077] like Figure 7 As shown, in order to improve the efficiency of taking out the black stone composite material tube 9 , the present disclosure provides a first pulling member 101 and a second pulling member 102 , which work together to take out the black stone composite material tube 9 from the thermal setting mechanism 7 .

[0078] Specifically, the first pulling member 101 and the second pulling member 102 can selectively clamp or release the black stone composite material tube 9. The first pulling member 101 and the second pulling member 102 are respectively provided with a first moving member 103 and a second moving member 104, so that the first pulling member 101 and the second pulling member 102 can move along the axial direction of the black stone composite material tube 9.

[0079] The specific process of taking out the items is as follows: when the first pulling member 101 clamps the black stone composite material tube 9, the second pulling member 102 is released, and the first pulling member 101 moves with the black stone composite material tube 9 pulled by the first moving member 103, while the second pulling member 102 does not move.

[0080] When the first pulling member 101 moves to the first extreme position, the second pulling member 102 clamps the black stone composite material tube 9, and the first pulling member 101 releases the black stone composite material tube 9. Then, the second pulling member 102 moves with the black stone composite material tube 9 pulled by the second moving member 104, and the first pulling member 101 returns to the first original position under the action of the first moving member 103.

[0081] When the second pulling member 102 reaches the second extreme position, the black stone composite material tube 9 is released, and the first pulling member 101 that returns to the original position clamps the black stone composite material tube 9 again to pull the black stone composite material tube 9. During this period, the second pulling member 102 returns from the second extreme position to the second original position.

[0082] It should be noted that the first original position and the second original position mentioned above are the starting positions of the first pulling member 101 and the second pulling member 102, and then the first pulling member 101 pulls the basalt composite material tube to move along the axis direction of the basalt composite material tube to the farthest position that the first pulling member 101 can reach, that is, the first extreme position. Similarly, the second pulling member 102 pulls the basalt composite material tube to move along the axis direction of the basalt composite material tube to the farthest position that the second pulling member 102 can reach, that is, the second extreme position.

[0083] In this way, the black stone composite material tube 9 is taken out from the heat setting mechanism 7, thereby improving the efficiency of taking out.

[0084] In a third aspect, the present disclosure provides a basalt composite material tube 9, which is made by the manufacturing method of the basalt composite material tube 9. The basalt composite material tube 9 has the characteristics of low cost and high strength, and is suitable for application in many livelihood industries.
