Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a fiber directional arrangement device and method. Background Art

[0002] Adding fibers to materials can improve the ductility, tensile strength, crack resistance and other properties of the materials. Fiber directional arrangement refers to the orderly arrangement of fibers in a specific direction in the material. Steel fiber concrete is a new type of composite material formed by adding short and thin steel fibers to ordinary concrete. Steel fiber concrete is favored for its excellent performance in tensile strength, bending resistance and impact resistance. Compared with traditional concrete, steel fiber concrete has higher toughness and crack resistance, and can effectively resist the expansion of cracks, thereby improving the durability and safety of concrete structures. However, the uneven distribution of steel fibers in concrete seriously restricts its application in practical engineering. Traditional steel fiber concrete only adds steel fibers to concrete and stirs them. The steel fibers are randomly distributed, and the steel fibers are mostly distributed in aggregate in the concrete, which makes it impossible to effectively improve the strength and toughness of some areas of the concrete. The steel fibers in the corresponding areas cannot effectively play their bridging role, thus affecting the performance of the overall concrete structure.

[0003] Ensuring uniform distribution and directional arrangement of steel fibers in concrete is the key to solving the problem of uneven distribution of steel fibers in concrete. Only when steel fibers can be arranged along or parallel to the principal stress direction can they fully play their role in reinforcing concrete. Directed steel fibers can more effectively resist the expansion of cracks and improve the overall tensile and bending properties of concrete. Therefore, in order to give full play to the advantages of steel fibers, measures must be taken to ensure their uniform distribution and directional arrangement in concrete, thereby effectively improving the mechanical properties and performance of concrete.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The purpose of the present invention is to provide a fiber directional arrangement device and method to solve the problems existing in the prior art, so as to enable the fibers to be more accurately oriented and arranged, thereby improving the mechanical properties and performance of the composite material.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] like Figures 1 to 4As shown, this embodiment provides a fiber oriented arrangement device 100, including a flow induced orientation device 1 and a magnetic field induced orientation device 2, wherein: the flow induced orientation device 1 includes a first pipe segment 101 and a second pipe segment 102 which are interconnected, the angle between the first pipe segment 101 and the second pipe segment 102 is an obtuse angle, and the first pipe segment 101 can be vertically arranged; the magnetic field induced orientation device 2 can form an oriented magnetic field in the inner cavity of the second pipe segment 102. The above-mentioned fiber directional arrangement device 100 induces the positioning of the composite material through the flow induced orientation device 1 and the magnetic field induced orientation device 2. The induced positioning effects of the flow induced orientation device 1 and the magnetic field induced orientation device 2 can complement each other, and can make the fibers more accurately oriented. Specifically: the working principle of the flow induced orientation device 1 is: utilizing the fluidity of the composite material, by controlling the flow direction and speed of the composite material, guiding the fibers to deposit to a predetermined position, so that the fibers are evenly distributed in the concrete, which is beneficial to improving the overall performance of the concrete, but because the flow state of the composite material may be affected by various factors, such as temperature, viscosity, etc., the orientation accuracy of the flow induced orientation device 1 is poor; the working principle of the magnetic field induced orientation device 2 is: by adjusting the magnetic field strength and direction of the magnetic field induced orientation device 2, the movement direction and speed of the fibers are controlled, so that they move and deposit along a predetermined path, to achieve directional arrangement of the fibers in the composite material, and the orientation accuracy is high, but the high fluidity of the composite material may significantly increase the movement speed of the fibers in the composite material, affecting the stability of its movement, and increasing the complexity of controlling the position and direction of the fibers. The fiber orientation arrangement device 100 first performs preliminary induced orientation on the composite material through the flow induced orientation device 1, thereby improving the uniformity of the fibers in the composite material; and because the angle between the first pipe segment 101 and the second pipe segment 102 is an obtuse angle, when the first pipe segment 101 is vertically arranged, the discharge port of the second pipe segment 102 is inclined downwardly arranged; after adding the composite material mixed with fibers into the first pipe segment 101, the composite material can pass through the first pipe segment 101 and the second pipe segment 102 in sequence under the action of gravity, and by setting the first pipe segment 101 vertically, the composite material can obtain a larger acceleration to enhance its fluidity and accelerate the dispersion of the fibers by utilizing the action of gravity; the second pipe segment 102 inclined downwardly can make the composite material more evenly distributed in a horizontal or approximately horizontal direction, thereby reducing the flow velocity of the composite material; by applying a magnetic field to the second pipe segment 102, it is possible to achieve precise control of the fibers in the mixed material, and better cope with the influence of the fluidity of the composite material on the induced orientation, thereby improving the mechanical properties and performance of the composite material.

[0037] It should be noted that the first pipe section 101 is preferably arranged vertically when used, but is not limited to the vertical arrangement and can be adjusted according to the actual project. However, in order to avoid affecting the fiber orientation effect, it is recommended to adjust the angle range to no more than 30°.

[0038] In this embodiment, the flow induction orientation device 1 further includes a third pipe segment 103, the feed port of the third pipe segment 103 is connected and communicated with the discharge port of the second pipe segment 102, the center line of the third pipe segment 103 is perpendicular to the center line of the first pipe segment 101, and when the first pipe segment 101 is vertically arranged, the third pipe segment 103 is horizontally arranged; the magnetic field induction orientation device 2 can form an orientation magnetic field in the inner cavity of the third pipe segment 103. A horizontal third pipe segment 103 is arranged behind the second pipe segment 102 which is arranged obliquely, and the composite material passing through the second pipe segment 102 can continue to flow forward in the third pipe segment 103 under the action of gravity, and the flow rate of the composite material in the third pipe segment 103 is reduced, which is more conducive to the parallel distribution of the fibers, and further improves the uniformity of the fiber dispersion.

[0039] In this embodiment, the flow induced orienting device 1 also includes a connecting pipe segment 104, the two ends of which are respectively connected and communicated with the outlet of the first pipe segment 101 and the feed port of the second pipe segment 102, and the magnetic field induced orienting device 2 can form an oriented magnetic field in the inner cavity of the connecting pipe segment 104.

[0040] In this embodiment, the magnetic field induced orientation device 2 includes a first magnetic field induced orientation member 201, a first insulating member 202, a second magnetic field induced orientation member 203, a second insulating member 204 and a third magnetic field induced orientation member 205 connected in sequence, and the first magnetic field induced orientation member 201, the second magnetic field induced orientation member 203, the third magnetic field induced orientation member 205, the first insulating member 202 and the second insulating member 204 are all cylindrical; the first magnetic field induced orientation member 201 is sleeved outside the connecting pipe section 104, and the first magnetic field induced orientation member 201 can be connected to the connecting pipe section 104. a directional magnetic field is formed in the inner cavity of the first pipe segment 101; a second magnetic field inducing directional member 203 is sleeved outside the first pipe segment 101, and the second magnetic field inducing directional member 203 can form a directional magnetic field in the inner cavity of the first pipe segment 101; a third magnetic field inducing directional member 205 is sleeved outside the second pipe segment 102, and the third magnetic field inducing directional member 205 can form a directional magnetic field in the inner cavity of the second pipe segment 102; the first insulating member 202 is sleeved at the junction of the connecting pipe segment 104 and the first pipe segment 101, and the second insulating member 204 is sleeved at the junction of the first pipe segment 101 and the second pipe segment 102. By arranging insulating parts between the first magnetic field induced orientation member 201 and the second magnetic field induced orientation member 203, and between the second magnetic field induced orientation member 203 and the third magnetic field induced orientation member 205, the mutual transmission and interference of the magnetic field between the first magnetic field induced orientation member 201, the second magnetic field induced orientation member 203, and the third magnetic field induced orientation member 205 are effectively prevented, ensuring that each magnetic field induced orientation member can be operated independently, thereby improving the control accuracy and efficiency of the entire system, making the overall layout of the magnetic field more stable, and ensuring the uniformity and controllability of the fiber directional arrangement process.

[0041] As a preferred embodiment, the first insulating member 202 and the second insulating member 204 are both insulating rubber insulation layers.

[0042] In this embodiment, a cooling device 3 is also included, and the cooling device 3 can cool the magnetic field induced orientation device 2.

[0043] In this embodiment, the cooling device 3 includes a conduit 301, a thermal circulation pump 302 and a coolant cooling component. The conduit 301 can be connected to the thermal circulation pump 302 and the coolant cooling component. The conduit 301, the thermal circulation pump 302 and the coolant cooling component can form a coolant circulation loop; the coolant in the conduit 301 can absorb the heat generated by the magnetic field induced orientation device 2. The thermal circulation pump 302 uses the pressure difference generated by the temperature difference to drive the coolant to flow in the circulation loop, without the need for an external power supply. The thermal circulation pump 302 preferably uses a miniature hot water circulation pump of model DC50G. The coolant circulates in the conduit 301, absorbs the heat generated by the magnetic field induced orientation device 2 by the current, and the coolant after absorbing the heat flows to the coolant cooling component, and the coolant cooling component cools the coolant. In this process, the coolant releases heat, the temperature drops, and then flows back to the high temperature zone again, forming a closed loop, thereby continuously absorbing heat from the magnetic field induced orientation device 2 and dissipating heat at the coolant cooling component. The coolant cooling component is usually a radiator or cooling device 3 located outside the device or in a colder environment.

[0044] In this embodiment, the cooling device 3 also includes a pressure safety valve, which is arranged in the coolant circulation loop. When the pressure fluctuation of the coolant exceeds the set value due to temperature change, the pressure safety valve automatically opens to release the pressure to protect the system safety.

[0045] In this embodiment, the cooling device 3 also includes a leakage detection device to monitor in real time whether there is a coolant leak in the cooling device 3. Once a leak is detected, the device will automatically sound an alarm and take corresponding emergency measures, such as stopping the operation of the device, cutting off the coolant supply, etc., to prevent the coolant leakage from causing damage to the device and the environment. During the design and installation of the cooling device 3, ensure that the pipeline is firmly connected, and use connectors and sealing materials with good sealing performance to reduce the risk of leakage.

[0046] In this embodiment, the first magnetic field inducing orientation member 201 , the second magnetic field inducing orientation member 203 , and the third magnetic field inducing orientation member 205 are all coils.

This arrangement not only maximizes the uniformity and intensity of the magnetic field, but also helps to focus the magnetic field, ensuring that the fibers can be oriented and arranged in a predetermined direction.

[0048] As a preferred embodiment, the first magnetic field induced orientation member 201, the second magnetic field induced orientation member 203, and the third magnetic field induced orientation member 205 are spiral coils composed of several high-conductivity wires. It should be noted that the optimal wire spacing can be determined by experiments and simulation analysis to balance the magnetic field strength and heat dissipation requirements, and ensure the accuracy of magnetic field stability and fiber orientation. The material of the conduit 301 is copper, which has extremely high thermal conductivity, can quickly absorb heat, and take away the heat through the circulating coolant, keep the temperature of the equipment stable, improve the efficiency and safety of the magnetic field induced orientation device 2, and extend the service life of the equipment. The conduit 301 is provided with a spiral groove along the length direction of the first magnetic field induced orientation member 201, the second magnetic field induced orientation member 203, and the third magnetic field induced orientation member 205, and the high-conductivity wire is embedded in the spiral groove, so that the high-conductivity wire is evenly distributed along the surface of the conduit 301. The conduit 301 runs through the interior of the entire magnetic field induced orientation device 2, and is in close contact with the first magnetic field induced orientation member 201, the second magnetic field induced orientation member 203, and the third magnetic field induced orientation member 205 with high conductivity. The conduit 301 is designed as a through-type structure, and an internal thread or a heat dissipation fin structure is used inside to increase the contact area between the coolant and the wall of the conduit 301, thereby improving the heat dissipation efficiency. It should be noted that the resistance during the flow of the coolant can be reduced by optimizing the bending radius and path of the conduit 301, ensuring that the coolant can quickly and evenly take away the heat, maintain the stable operation of the system, and ensure that the magnetic field strength is not affected by temperature changes. The coolant is water, which is energy-saving and environmentally friendly, and effectively reduces the operating cost.

[0049] In this embodiment, it also includes a support skeleton 4, which is mounted outside the flow induction orientation device 1, the catheter 301 is wrapped around the support skeleton 4, and the first magnetic field induction orientation component 201, the second magnetic field induction orientation component 203, and the third magnetic field induction orientation component 205 are all wrapped around the catheter 301.

[0050] In this embodiment, an insulating protective shell 5 is also included, on which a magnetic shielding layer is arranged, and the magnetic field induced orientation device 2 is arranged in the magnetic shielding layer. The magnetic shielding layer can reduce the leakage of the magnetic field of the magnetic field induced orientation device 2 to the surrounding environment, improve the utilization rate of the magnetic field energy, and allow more magnetic field forces to act on the fiber. In addition, the magnetic shielding layer can also prevent the influence of external magnetic field interference on the internal magnetic field orientation, ensuring that the fiber is accurately oriented and arranged under a predetermined magnetic field environment. The magnetic shielding layer is preferably made of high-performance magnetic shielding material, and more preferably, the magnetic shielding layer is made of Permalloy to enhance the magnetic field shielding effect.

A feed port with a wide top is provided at the upper end of the first pipe section 101. Reinforcing ribs are provided on the support frame 4 to improve the stability and deformation resistance of the device when dealing with electromagnetic force and its own gravity, to ensure that the conduit 301 and the magnetic field induced orientation device 2 can maintain a stable positional relationship during the operation of the device, thereby maintaining the stability of the magnetic field, and further improving the mechanical properties of the composite material.

[0052] As a preferred embodiment, the support frame 4 is made of corrosion-resistant, high-strength stainless steel material, and is wrapped with high-temperature resistant insulating material on the outside, so as to withstand the high temperature and electromagnetic force generated during continuous operation.

[0053] As a preferred embodiment, a control device is also included. The first magnetic field induced orientation member 201, the second magnetic field induced orientation member 203, and the third magnetic field induced orientation member 205 are all connected to the control device. The control device is provided with an interactive interface, which can facilitate the operator to control the opening and closing, current, etc. of the first magnetic field induced orientation member 201, the second magnetic field induced orientation member 203, and the third magnetic field induced orientation member 205. It is easy to operate and does not require complicated manual intervention, which greatly reduces the construction difficulty and operation errors.
