Description

Technical Field

[0001] This invention relates to the field of concrete production technology, specifically to a high-strength, high-toughness concrete production equipment and its production method. Background Technology

[0002] Hydrogel fiber is a type of artificial spider silk with a tensile strength of 850 MPa, high toughness of 370 MJ m⁻³, and 95% damping capacity. Adding hydrogel fiber to concrete can significantly improve its mechanical properties and durability. The addition of hydrogel fiber creates a randomly distributed network structure, thereby inhibiting early plastic shrinkage and thermal cracking in concrete, thus increasing its flexural strength. It can also reduce the internal porosity of concrete and significantly optimize its mechanical properties, thereby improving its compressive strength and modulus of elasticity, as well as its toughness and impact resistance.

[0003] Currently, hydrogel fibers are mostly added to concrete after the concrete has been fully mixed. The fibers are weighed quantitatively using appropriate weighing equipment and then added to the concrete mixing plant. Continuous mixing is then used to evenly distribute the hydrogel fibers throughout the concrete. However, because hydrogel fibers tend to clump together after absorbing water, and their friction increases upon contact with concrete, they are difficult to distribute evenly during mixing, resulting in concrete performance that fails to meet design specifications.

[0004] Therefore, the research objective of this invention is to design a high-strength and high-toughness concrete production equipment and its production method that can effectively and uniformly disperse hydrogel fibers into concrete, thereby effectively improving the strength and toughness of concrete, without affecting the normal mixing operation of concrete. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a high-strength and high-toughness concrete production equipment and production method, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this invention is:

[0007] A high-strength, high-toughness concrete production equipment, comprising:

[0008] A mixing container is fixedly installed on a corresponding bracket, and the mixing container is equipped with a stirring mechanism for fully mixing the materials.

[0009] A liquid material hopper, installed on a support above the mixing container, is used for quantitative storage of liquid material and quantitative discharge of liquid material into the mixing container;

[0010] A solid material hopper, inclined on the support and driven by a corresponding hopper drive mechanism, is used to quantitatively store solid materials and quantitatively discharge solid materials into the mixing container.

[0011] A cement hopper is mounted on the support via several evenly distributed first weighing devices. The discharge end of the cement hopper is connected to the mixing container. The upper side of the interior of the cement hopper is divided into a cement storage chamber and a fiber storage chamber. The bottom sides of the cement storage chamber and the fiber storage chamber are respectively provided with corresponding discharge holes.

[0012] A cement mixer includes a drive shaft driven by a corresponding first lifting drive mechanism. The bottom end of the drive shaft is fixedly connected to a plurality of first partitions in a circular array. The bottom of the drive shaft is provided with a connecting member facing downward through a second lifting drive mechanism. The outer side of the connecting member is fixedly connected to a plurality of second partitions arranged in a circular array, which are staggered with the first partitions.

[0013] A rotary drive mechanism is provided, wherein the drive shaft is rotatably mounted to the output shaft end of the first lifting drive mechanism, and the rotary drive mechanism is used to drive the drive shaft to rotate. During the weighing and storage process, the drive shaft rises to its position, and the connecting piece moves upward to the second partition plate and abuts against the two adjacent first partition plates to close the discharge hole. During the quantitative feeding process, the drive shaft descends to its position, and the connecting piece moves downward to the second partition plate and is spaced apart from the first partition plate. The rotary drive mechanism drives the drive shaft to rotate to stir and disperse the cement and hydrogel fibers during the feeding process.

[0014] The mixing container has a guide hole and a set of inlets at the top, and an outlet at the bottom. The outlet is equipped with a switch door driven by a corresponding feeding cylinder. The liquid material hopper is mounted on a support on the upper side of the mixing container through several evenly distributed second weighing devices. The outlet of the liquid material hopper is connected to the inlet of the mixing container through a first discharge valve. The upper part of the liquid material hopper is connected to a corresponding liquid material feed pipe.

[0015] The top side of the cement hopper is connected to the discharge end of the corresponding cement lifting auger, and the other side is provided with a corresponding hydrogel fiber guide hopper. The hydrogel fiber guide hopper is connected to the discharge end of the corresponding hydrogel fiber conveyor belt. The discharge end of the cement hopper is connected to the other inlet of the mixing container through a corresponding second discharge valve.

[0016] The feed end of the cement lifting auger is connected to the discharge end of the corresponding cement storage silo. The discharge end of the cement storage silo is equipped with a corresponding anti-accumulation mechanism. The anti-accumulation mechanism includes multiple vibration transmission rods evenly distributed and fixed to the bottom side of the cement storage silo. The vibration transmission rods extend through to the outside of the cement storage silo and are fixed to the corresponding vibration transmission ring plate. Buffer washers fixed to the outer wall of the cement storage silo are respectively provided on both sides of the vibration transmission ring plate. The vibration transmission ring plate is connected to the auger motor of the cement lifting auger through corresponding elastic elements.

[0017] The first lifting drive mechanism uses a lifting drive cylinder, and the second lifting drive mechanism uses an electromagnet. The drive shaft and the connecting member each have corresponding grooves on opposite sides. The second lifting drive mechanism is embedded in the groove of the drive shaft, and the drive shaft and the groove of the connecting member are connected by a corresponding helical spring. A connecting pipe is fixedly attached upwards to the connecting member and is movably inserted into the groove of the drive shaft. The connecting pipe is sleeved around the helical spring and has a keyway fit with the side wall of the groove of the drive shaft. The rotation drive mechanism uses a drive motor. The drive shaft is rotatably mounted to the output shaft end of the first lifting drive mechanism via a corresponding connecting bearing, and the drive shaft is connected to the output shaft end of the rotation drive mechanism via a gear meshing connection. The height of the gear connected to the drive shaft is greater than the lifting stroke of the drive shaft.

[0018] The hopper drive mechanism includes a lifting motor and a drum that is driven to the output shaft end of the lifting motor. A pulling rope for pulling the solid material hopper is wound on the drum. A corresponding automatic valve is provided at the bottom of the solid material hopper. When the solid material hopper is lifted to the point where its bottom is directly opposite the guide hole, the automatic valve opens to discharge the material in the solid material hopper into the mixing container.

[0019] The outer side of the support is provided with a connecting hopper for receiving solid materials. A corresponding guide hopper is provided horizontally on the bottom side of the connecting hopper. A feeding conveyor belt for feeding solid materials into the solid material hopper is provided on the bottom side of the guide hopper.

[0020] The feed end of the hydrogel fiber conveyor belt is inclined upward, and the periphery of the hydrogel fiber conveyor belt is covered with a corresponding isolation cover. A hydrogel fiber storage hopper with its discharge end facing the feed end of the hydrogel fiber conveyor belt is fixed to the upper part of the bottom side of the isolation cover. A cleaning pipe with a cleaning valve is provided at the lower part of the bottom side of the isolation cover.

[0021] The mixing mechanism includes a set of mixing shafts driven by corresponding drive motors. Several corresponding connecting arms are obliquely fixed to the mixing shafts in an arc shape. Corresponding scraper plates are obliquely fixed to the outer ends of the connecting arms. Corresponding limiting grooves are recessed on the back sides of the scraper plates. Corresponding rake rods are oscillatingly installed within the limiting grooves, with their ends protruding outwards. When the drive motor starts rotating forward, the arc-shaped connecting arms and scraper plates scrape the material. The protruding parts of the rake rods, under force, drive the rake rods to unfold outwards and disperse the material. When the drive motor starts rotating in reverse, the arc-shaped connecting arms and scraper plates scrape and mix the material. The rake rods, under force, embed themselves into the corresponding limiting grooves.

[0022] A method for producing high-strength, high-toughness concrete, based on the aforementioned high-strength, high-toughness concrete production equipment, includes the following specific processing steps:

[0023] S1, the drive shaft rises to the position, the connecting piece moves up to the second partition and abuts against the two adjacent first partitions to seal the discharge hole, and then 340-360 parts by weight of cement and 20-30 parts by weight of hydrogel fiber are quantitatively added to the cement hopper.

[0024] S2, the drive shaft descends to its position, the connecting piece descends until it leaves the second partition and is spaced apart from the first partition, and then the rotation drive mechanism drives the drive shaft to rotate to stir and disperse the cement and hydrogel fibers during the feeding process, so that the cement and hydrogel fibers enter the mixing container evenly.

[0025] At the same time, 550-650 parts by weight of sand and 140-160 parts by weight of silica fume are added to the mixing container through the solid material hopper.

[0026] S3, the stirring mechanism is activated to mix the cement, hydrogel fiber, sand and silica fume that have entered the mixing container;

[0027] S4, 105-115 parts by weight of water, 18-22 parts by weight of water-reducing agent, 38-42 parts by weight of high-strength admixture, and 28-32 parts by weight of compacting agent are added to the mixing container through the liquid material hopper.

[0028] S5, the mixing mechanism continues to mix the materials in the mixing container until the materials are mixed evenly to obtain concrete.

[0029] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0030] 1) The present invention first improves the design of the cement hopper. Based on its original weighing function, it divides the hopper into a cement storage chamber and a fiber storage chamber, and sets corresponding discharge holes on the bottom side of the cement storage chamber and the fiber storage chamber respectively. Then, a cement mixer and a rotating drive mechanism are added.

[0031] The cement mixer uses a first lifting drive mechanism to raise and lower the drive shaft, and a second lifting drive mechanism to raise and lower the connecting parts, thereby controlling the switching of the positions of the staggered first and second partitions. During the weighing and storage process, the drive shaft is raised to its designated position, and the connecting parts are moved upwards until the second partition abuts against the two adjacent first partitions, sealing the discharge holes of the cement storage chamber and the fiber storage chamber, thus facilitating the quantitative weighing of cement and hydrogel fibers. During the quantitative dispensing process, the drive shaft is lowered to its designated position, and the connecting parts are moved downwards until the second partition separates from the first partition, creating an interval between them, to facilitate the synchronous output of cement and hydrogel fibers. Then, the drive shaft is rotated by the rotation drive mechanism, thus mixing and dispersing the cement and hydrogel fibers during the dispensing process. This effectively disperses the hydrogel fibers evenly into the concrete without affecting the normal concrete mixing operation, thereby significantly improving the strength and toughness of the produced concrete.

[0032] 2) The discharge end of the cement lifting auger of the present invention is connected to the discharge end of the cement storage silo. The discharge end of the cement storage silo is provided with a corresponding anti-accumulation mechanism. The anti-accumulation mechanism includes a plurality of vibration transmission rods evenly distributed and fixed to the bottom side of the cement storage silo. The vibration transmission rods extend through to the outside of the cement storage silo and are fixed to the corresponding vibration transmission ring plate. Buffer washers fixed to the outer wall of the cement storage silo are respectively provided on both sides of the vibration transmission ring plate. The vibration transmission ring plate is connected to the auger motor of the cement lifting auger through a corresponding elastic element.

[0033] By incorporating elastic elements, the vibrations generated during the operation of the auger motor are smoothly transmitted to the vibration transmission ring plate. These vibrations are then effectively transmitted to each vibration transmission rod, thereby agitating the cement at the discharge end of the cement storage hopper. This prevents cement from accumulating at the discharge end and hindering smooth discharge, thus significantly improving the practical effectiveness of the invention. Most importantly, the vibration power of this anti-accumulation mechanism originates from the auger motor, effectively reducing energy consumption and minimizing the impact of the vibrations generated by the auger motor on the cement discharge hopper. This, in turn, effectively assists in improving the accuracy of weighing and storing cement and hydrogel fibers.

[0034] 3) The first lifting drive mechanism of the present invention adopts a lifting drive cylinder, and the second lifting drive mechanism adopts an electromagnet. The second lifting drive mechanism is embedded in the groove of the drive shaft, and the drive shaft and the groove of the connecting part are connected by a corresponding helical spring, thereby ensuring the stable lifting drive of the drive shaft and the connecting part. On this basis, the present invention further fixes a connecting pipe that can be movably inserted into the groove of the drive shaft on the connecting part. The connecting pipe is sleeved on the periphery of the helical spring and is keyed to the side wall of the groove of the drive shaft. In this way, it can effectively ensure the synchronous rotation drive of the drive shaft and the connecting part, and can also ensure the stable positioning and limiting installation of the connecting part, i.e., the second partition, thereby effectively improving the practical effect of the present invention.

[0035] 4) The drive shaft of the present invention is connected to the output shaft end of the rotary drive mechanism by a gear meshing connection, and the height of the gear connected to the drive shaft is greater than the lifting stroke of the drive shaft, so as to ensure that the lifting process of the drive shaft will not cause the transmission connection between it and the rotary drive mechanism to fail, thereby effectively improving the practical effect of the present invention.

[0036] 5) The feed end of the hydrogel fiber conveyor belt of the present invention is inclined upward, and a corresponding isolation cover is provided around the hydrogel fiber conveyor belt. A hydrogel fiber storage hopper with its discharge end facing the feed end of the hydrogel fiber conveyor belt is fixedly connected to the upper part of the bottom side of the isolation cover, and a cleaning pipe equipped with a cleaning valve is provided at the lower part of the bottom side of the isolation cover. The hydrogel fiber stored in the hydrogel fiber storage hopper is effectively transported by the hydrogel fiber conveyor belt. A small amount of dispersed material generated during the transport of hydrogel fibers is collected by the isolation cover. During use, it is only necessary to periodically collect and reuse the material concentrated at the bottom side of the isolation cover by passing it through the cleaning pipe.

[0037] 6) The stirring mechanism of the present invention includes a set of stirring shafts driven by corresponding drive motors. Several corresponding connecting arms are fixedly connected to the stirring shafts in an arc shape. The outer ends of the connecting arms are respectively fixedly connected to corresponding scraper plates. Most importantly, the back side of the scraper plates is respectively recessed with corresponding limiting grooves, and corresponding rake rods are oscillatingly installed in the limiting grooves. The rake rods are embedded in the limiting grooves and their ends protrude outwards. Before the liquid material is added, the drive motor can be started and rotated forward, causing the arc-shaped connecting arm and scraper to scrape the material. At this time, the hydrogel fibers have not absorbed water and do not form significant adhesion with other materials. Therefore, the protrusions of the rake bar can drive the rake bar to expand outward under force to disperse the material. Then, the liquid material is added and the drive motor is started and rotated in reverse, causing the arc-shaped connecting arm and scraper to scrape and stir the material. At this time, the hydrogel fibers absorb water and form significant adhesion with other materials, while the rake bar embeds into the corresponding limiting groove under force, thereby preventing the hydrogel fibers from agglomerating and forming clumps. In this way, the dispersion uniformity of hydrogel fibers in concrete materials can be significantly improved, thereby significantly improving the strength and toughness of the produced concrete.

[0038] 7) In the preparation process of the present invention, the solid materials, cement and hydrogel fibers are fully dispersed and stirred in advance by the improved equipment, and then the liquid materials are added in place. In the process of stirring the overall materials, the problem of aggregation of hydrogel fibers due to increased viscosity and friction is effectively overcome, thereby effectively and significantly improving the strength and toughness of the produced concrete.

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0054] Example 1:

[0055] refer to Figure 1-13 A high-strength, high-toughness concrete production equipment, comprising:

[0056] A mixing container 1 is fixedly installed on a corresponding bracket 2. The mixing container 1 is equipped with a stirring mechanism 3 for fully mixing the materials.

[0057] The liquid material hopper 4 is installed on the support 2 on the upper part of the mixing container 1, and is used to quantitatively store liquid material and quantitatively discharge liquid material into the mixing container 1;

[0058] Solid material hopper 5 is inclinedly mounted on the support 2 and driven by a corresponding hopper drive mechanism 6. It is used to quantitatively store solid materials and quantitatively discharge solid materials into the mixing container 1.

[0059] The cement hopper 7 is installed on the support 2 by a number of evenly distributed first weighing devices 8. The discharge end of the cement hopper 7 is connected to the mixing container 1. The upper side of the interior of the cement hopper 7 is divided into a cement storage chamber 701 and a fiber storage chamber 702. The bottom sides of the cement storage chamber 701 and the fiber storage chamber 702 are respectively provided with corresponding discharge holes facing downward.

[0060] The cement mixer 9 includes a drive shaft 902 driven by a corresponding first lifting drive mechanism 901. The bottom end of the drive shaft 902 is fixedly connected to a plurality of first partitions 903 in a circular array. The bottom of the drive shaft 902 is provided with a connecting member 905 facing downward through a second lifting drive mechanism 904. The outer side of the connecting member 905 is fixedly connected to a plurality of second partitions 906 arranged in a circular array, which are staggered with the first partitions 903.

[0061] A rotation drive mechanism 10 is used to drive the drive shaft 902 to rotate. During the weighing and storage process, the drive shaft 902 rises to its position, and the connecting piece 905 moves upward to the second partition 906 and abuts against the two adjacent first partitions 903 to close the discharge hole. During the quantitative feeding process, the drive shaft 902 descends to its position, and the connecting piece 905 moves downward to the second partition 906 and is spaced apart from the first partition 903. The rotation drive mechanism 10 drives the drive shaft 902 to rotate to stir and disperse the cement and hydrogel fibers during the feeding process.

[0062] The present invention first improves the design of the cement hopper 7. Based on its original weighing function, it is divided into a cement storage chamber 701 and a fiber storage chamber 702. Corresponding discharge holes are provided on the bottom side of the cement storage chamber 701 and the fiber storage chamber 702 respectively. Then, a cement mixer 9 and a rotation drive mechanism 10 are added.

[0063] The first lifting drive mechanism 901 of the cement mixer 9 drives the drive shaft 902 to rise and fall, and the second lifting drive mechanism 904 drives the connecting piece 905 to rise and fall, thereby switching the positions of the staggered first partition 903 and second partition 906. During the weighing and storage process, the drive shaft 902 is controlled to rise to the designated position, and the connecting piece 905 is controlled to move upward to the second partition 906 to abut between the two adjacent first partitions 903, thereby sealing the discharge holes of the cement storage chamber 701 and the fiber storage chamber 702, which facilitates the quantitative weighing of cement and hydrogel fiber. During the quantitative feeding process, the drive shaft 902 is controlled to fall to the designated position, and the connecting piece 905 is controlled to move downward to the second partition 906 and be spaced apart from the first partition 903, so as to facilitate the synchronous output of cement and hydrogel fiber. Then, the drive shaft 902 is rotated by the rotation drive mechanism 10, thus stirring and dispersing the cement and hydrogel fiber during the feeding process. This effectively disperses hydrogel fibers evenly into the concrete without affecting the normal mixing process, thereby significantly improving the strength and toughness of the produced concrete.

[0064] The mixing container 1 has a guide hole 101 and a set of inlets 102 at the top, and an outlet at the bottom. The outlet is equipped with a switch door 12 driven by a corresponding feeding cylinder 11. The liquid material hopper 4 is mounted on a support 2 on the upper side of the mixing container 1 through several evenly distributed second weighing devices 13. The outlet end of the liquid material hopper 4 is connected to the inlet 102 of the mixing container 1 through a first discharge valve 14. The upper part of the liquid material hopper 4 is connected to a corresponding liquid material feed pipe 15.

[0065] The top side of the cement hopper 7 is connected to the discharge end of the corresponding cement lifting auger 16, and the other side is provided with a corresponding hydrogel fiber guide hopper 17. The hydrogel fiber guide hopper 17 is connected to the discharge end of the corresponding hydrogel fiber conveyor belt 18. The discharge end of the cement hopper 7 is connected to another inlet 102 of the mixing container 1 through a corresponding second discharge valve 19.

[0066] The feed end of the cement lifting auger 16 is connected to the discharge end of the corresponding cement storage silo 20. The discharge end of the cement storage silo 20 is provided with a corresponding anti-accumulation mechanism 21. The anti-accumulation mechanism 21 includes a plurality of vibration transmission rods 2101 evenly distributed and fixed to the bottom side of the cement storage silo 20. The vibration transmission rods 2101 extend through to the outside of the cement storage silo 20 and are fixed to the corresponding vibration transmission ring plate 2102. The two sides of the vibration transmission ring plate 2102 are respectively provided with buffer washers 2103 fixed to the outer wall of the cement storage silo 20. The vibration transmission ring plate 2102 and the auger motor of the cement lifting auger 16 are connected by a corresponding elastic element 2104.

[0067] The elastic element 2104 is designed to smoothly transmit the vibration generated during the operation of the auger motor to the vibration transmission ring plate 2102. The vibration is then effectively transmitted to each vibration transmission rod 2101 via the vibration transmission ring plate 2102, thereby shaking the cement on the discharge end side of the cement storage silo 20 to prevent cement from accumulating at the discharge end of the cement storage silo 20 and causing uneven discharge, thus effectively improving the practical effect of the invention. Most importantly, the vibration power of this anti-accumulation mechanism 21 comes from the auger motor, which can effectively reduce energy consumption and reduce the impact of the vibration generated by the auger motor on the cement discharge hopper 7, thereby effectively helping to improve the accuracy of weighing and storing cement and hydrogel fibers.

[0068] The first lifting drive mechanism 901 uses a lifting drive cylinder, and the second lifting drive mechanism 904 uses an electromagnet. The drive shaft 902 and the connecting member 905 each have corresponding grooves on opposite sides. The second lifting drive mechanism 904 is embedded in the groove of the drive shaft 902, and the drive shaft 902 and the groove of the connecting member 905 are connected by a corresponding helical spring 22. A connecting pipe 23 is fixedly connected upwards to the connecting member 905 and is movably inserted into the groove of the drive shaft 902. The connecting pipe 23 is sleeved around the helical spring 22 and is keyed to the side wall of the groove of the drive shaft 902. The rotation drive mechanism 10 uses a drive motor. The drive shaft 902 is rotatably mounted to the output shaft end of the first lifting drive mechanism 901 via a corresponding connecting bearing 24. The drive shaft 902 is connected to the output shaft end of the rotation drive mechanism 10 via a gear meshing connection, and the height of the gear connected to the drive shaft 902 is greater than the lifting stroke of the drive shaft 902.

[0069] The first lifting drive mechanism 901 of the present invention adopts a lifting drive cylinder, and the second lifting drive mechanism 904 adopts an electromagnet. The second lifting drive mechanism 904 is embedded in the groove of the drive shaft 902, and the drive shaft 902 and the groove of the connecting member 905 are connected by a corresponding helical spring 22, thereby ensuring the stable lifting drive of the drive shaft 902 and the connecting member 905. On this basis, the present invention further fixes a connecting pipe 23 that can be movably inserted into the groove of the drive shaft 902 onto the connecting member 905. The connecting pipe 23 is sleeved on the periphery of the helical spring 22 and is keyed to the side wall of the groove of the drive shaft 902. In this way, it can effectively ensure the synchronous rotation drive of the drive shaft 902 and the connecting member 905, and can also ensure the stable limiting installation of the connecting member 905, i.e., the second partition 906, thereby effectively improving the practical effect of the present invention.

[0070] The drive shaft 902 of the present invention is connected to the output shaft end of the rotary drive mechanism 10 by a gear meshing connection, and the height of the gear connected to the drive shaft 902 is greater than the lifting stroke of the drive shaft 902, so as to ensure that the lifting process of the drive shaft 902 will not cause the transmission connection between it and the rotary drive mechanism 10 to fail, thereby effectively improving the practical effect of the present invention.

[0071] The hopper drive mechanism 6 includes a lifting motor 601 and a drum 602 that is driven to the output shaft end of the lifting motor 601. A pulling rope 603 for pulling and driving the solid material hopper 5 is wound on the drum 602. A corresponding automatic valve is provided at the bottom of the solid material hopper 5. When the solid material hopper 5 is lifted to the point where its bottom is directly opposite the guide hole 101, the automatic valve opens to discharge the material in the solid material hopper 5 into the mixing container 1.

[0072] The outer side of the support 2 is provided with a connecting hopper 25 for receiving solid materials. A corresponding guide hopper 26 is provided horizontally on the bottom side of the connecting hopper 25. A feeding conveyor belt 27 for feeding solid materials into the solid material hopper 5 is provided on the bottom side of the guide hopper 26.

[0073] The feed end of the hydrogel fiber conveyor belt 18 is inclined upward, and the periphery of the hydrogel fiber conveyor belt 18 is covered with a corresponding isolation cover 28. A hydrogel fiber storage hopper 29 with its discharge end facing the feed end of the hydrogel fiber conveyor belt 18 is fixedly connected to the upper part of the bottom side of the isolation cover 28. A cleaning pipe 31 with a cleaning valve 30 is provided at the lower part of the bottom side of the isolation cover 28.

[0074] The hydrogel fiber stored in the hydrogel fiber storage hopper 29 is effectively transported by the hydrogel fiber conveyor belt 18. A small amount of loose material generated during the transport of the hydrogel fiber is collected by the isolation cover 28. During use, the material concentrated on the bottom side of the isolation cover 28 can be collected and reused by periodically passing through the cleaning pipe 31.

[0075] The stirring mechanism 3 includes a set of stirring shafts 302 driven by corresponding drive motors 301. Several corresponding connecting arms 303 are obliquely fixed to the stirring shafts 302 in an arc shape. The outer ends of the connecting arms 303 are obliquely fixed to corresponding scraper plates 304. The back side of the scraper plates 304 is respectively recessed with corresponding limiting grooves 32. Corresponding rake rods 33 are oscillatingly installed in the limiting grooves 32. The rake rods 33 are embedded in the limiting grooves 32, and the ends of the rake rods 33 are protruding outward. When the drive motor 301 starts to rotate forward, the arc-shaped connecting arms 303 and scraper plates 304 scrape the material. After being stressed, the protruding parts of the rake rods 33 are driven to unfold outward to rake and disperse the material. When the drive motor 301 starts to rotate in reverse, the arc-shaped connecting arms 303 and scraper plates 304 scrape and stir the material. After being stressed, the rake rods 33 are embedded in the corresponding limiting grooves 32.

[0076] When the liquid material is not yet added, the drive motor 301 can be started and rotated forward, causing the arc-shaped connecting arm 303 and scraper 304 to scrape the material. At this time, the hydrogel fibers do not absorb water and do not form significant adhesion with other materials. Therefore, the protrusion of the rake 33 can drive the rake 33 to expand outward after being stressed to disperse the material. Then, the liquid material is added and the drive motor 301 is started and rotated in reverse, causing the arc-shaped connecting arm 303 and scraper 304 to scrape and stir the material. At this time, the hydrogel fibers absorb water and form significant adhesion with other materials, while the rake 33 embeds into the corresponding limiting groove 32 after being stressed, thereby preventing the hydrogel fibers from agglomerating and forming clumps. In this way, the dispersion uniformity of the hydrogel fibers in the concrete material can be further improved, thereby significantly improving the strength and toughness of the produced concrete.

[0079] S1, the drive shaft 902 rises to the position, the connecting piece 905 moves up to the second partition 906 and abuts against the two adjacent first partitions 903 respectively to form a seal on the discharge hole, and then 350 parts by weight of cement and 25 parts by weight of hydrogel fiber are quantitatively added to the cement hopper 7 respectively.

[0080] S2, the drive shaft 902 descends to its position, the connector 905 descends to the second partition 906 and is spaced apart from the first partition 903, and then the rotation drive mechanism 10 drives the drive shaft 902 to rotate, so as to stir and disperse the cement and hydrogel fiber in the feeding process, so that the cement and hydrogel fiber enter the mixing container 1 evenly.

[0081] At the same time, 600 parts by weight of sand and 150 parts by weight of silica fume are added to the mixing container 1 through the solid material hopper 5;

[0082] S3, the stirring mechanism 3 is activated to mix and stir the cement, hydrogel fiber, sand and silica fume that have entered the mixing container 1;

[0083] S4, 110 parts by weight of water, 20 parts by weight of water-reducing agent, 40 parts by weight of high-strength additive, and 30 parts by weight of compacting agent are added to the mixing container 1 through the liquid material hopper 4.

[0084] S5, the stirring mechanism 3 continues to stir the material in the mixing container 1 until the material is stirred and mixed evenly to obtain concrete.

[0086] In the preparation process of this invention, the solid materials, cement and hydrogel fibers are fully dispersed and stirred in advance by the improved equipment, and then the liquid materials are added in place. In the process of stirring the overall materials, the problem of aggregation of hydrogel fibers due to increased viscosity and friction is effectively overcome, thereby effectively and significantly improving the strength and toughness of the produced concrete.
