Description

Technical Field

[0001] The present invention relates to the technical field of concrete production, and in particular to high-strength and high-toughness concrete production equipment and a production method thereof. Background Art

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

[0003] Currently, hydrogel fibers are typically added to concrete after the concrete has been thoroughly mixed. The fibers are weighed using appropriate weighing equipment and then added to the concrete mixing equipment, where they are continuously stirred to evenly distribute the fibers throughout the concrete. However, since hydrogel fibers tend to clump after absorbing water and experience increased friction upon contact with concrete, they are difficult to effectively distribute throughout the concrete during mixing, resulting in concrete performance that falls short of design values.

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

[0016] Compared with the prior art, the advantages and positive effects of the present invention are: 1) The present invention first improves the design of the cement hopper. On the basis of its original weighing function, it is divided into a cement storage chamber and a fiber storage chamber, and corresponding discharge holes are respectively provided downward on the bottom sides of the cement storage chamber and the fiber storage chamber. Then, a cement mixer and a rotation drive mechanism are added.

[0017] The cement mixer's first lifting drive mechanism drives the drive shaft up and down, and the second lifting drive mechanism drives the connector up and down to switch and control the positions of the staggered first and second partitions. During the weighing and storage process, the drive shaft is controlled to rise into position, and the connector is controlled to ascend to the second partition and abut between the two adjacent first partitions, thereby sealing the discharge holes of the cement storage chamber and the fiber storage chamber, thereby facilitating the quantitative weighing of cement and hydrogel fibers. During the quantitative unloading process, the drive shaft is controlled to descend into position, and the connector is controlled to descend to the second partition, leaving it and being spaced apart from the first partition, to facilitate the synchronous output of cement and hydrogel fibers. The drive shaft is then driven to rotate by the rotary drive mechanism, thereby stirring and dispersing the cement and hydrogel fibers during the unloading process. This effectively disperses the hydrogel fibers evenly into the concrete without affecting the normal mixing operation of the concrete, thereby effectively improving the strength and toughness of the produced concrete.

[0018] 2) The discharge end of the cement lifting auger of the present invention is connected to the discharge end of the cement storage bin, and the discharge end of the cement storage bin is provided with a corresponding anti-backlog mechanism, which includes a plurality of vibration transmission rods evenly distributed and fixed to the bottom side of the cement storage bin, and the vibration transmission rods extend through and extend to the outside of the cement storage bin and are fixed to the corresponding vibration transmission ring plate, and buffer washers fixed to the outer wall of the cement storage bin are respectively provided on both sides of the vibration transmission ring plate, and the vibration transmission ring plate and the auger motor of the cement lifting auger are connected through corresponding elastic parts.

[0019] By setting up the elastic member, the vibration generated during the operation of the auger motor is smoothly transmitted to the vibration transmission ring plate. The vibration is effectively transmitted to each vibration transmission rod along the vibration transmission ring plate, thereby shaking the cement on the discharge end of the cement storage bin to prevent the cement from being accumulated at the discharge end of the cement storage bin and causing its discharge to be unsmooth, thereby effectively improving the practical effect of the present invention. Most importantly, the vibration power of the anti-backlog mechanism comes from the auger motor, which can effectively reduce energy consumption and reduce the impact of the vibration generated by the operation of the auger motor on the cement discharge hopper, thereby effectively helping to improve the weighing and storage accuracy of cement and hydrogel fiber.

[0020] 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 piece are connected by corresponding coil springs, thereby ensuring the stable lifting drive of the drive shaft and the connecting piece; on this basis, the present invention further fixes a connecting piece on a connecting piece that can be movably inserted into the groove of the drive shaft. The connecting piece is sleeved on the periphery of the coil spring and is key-matched with 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 piece, and can ensure the stable limiting installation of the connecting piece, that is, the second partition, thereby effectively further improving the practical effect of the present invention.

[0021] 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 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 further improving the practical effect of the present invention.

[0022] 5) The feed end of the hydrogel fiber conveyor belt of the present invention is tilted upward, and the outer cover of the hydrogel fiber conveyor belt is equipped with a corresponding isolation cover. A hydrogel fiber storage hopper is fixedly connected to the upper bottom portion of the isolation cover, with the discharge end facing the feed end of the hydrogel fiber conveyor belt. A drainage pipe equipped with a drainage valve is installed at the lower bottom portion of the isolation cover. The hydrogel fiber conveyor belt effectively transports the hydrogel fibers stored in the hydrogel fiber storage hopper. The isolation cover collects the small amount of dispersed materials generated during the hydrogel fiber transportation process. During use, the materials concentrated on the bottom side of the isolation cover need only be periodically collected through the drainage pipe for reuse.

[0023] 6) The stirring mechanism of the present invention includes a group of stirring shafts driven by corresponding drive motors, and a number of corresponding connecting arms are fixedly connected to the stirring shafts in an arc shape. The outer ends of the connecting arms are fixedly connected to corresponding scraping plates in an oblique manner. The most important thing is that the back sides of the scraping plates are respectively recessed with corresponding limiting grooves, and the corresponding rake rods are swingably installed in the limiting grooves. The rake rods are embedded in the limiting grooves, and their ends are protruding outwards. When the liquid material is not added in place, the drive motor can be started to rotate forward, so that the arc-shaped connecting arm and the scraper can scrape the material. At this time, the hydrogel fiber has not absorbed water and does not form obvious adhesion with other materials. Therefore, the raised part of the rake rod can drive the rake rod to expand outward to rake the material after being subjected to force; then the liquid material is added in place, and the drive motor is started to reverse, so that the arc-shaped connecting arm and the scraper can shovel and stir the material. At this time, the hydrogel fiber absorbs water and forms obvious adhesion with other materials, and the rake rod is embedded in the corresponding limit groove after being subjected to force, thereby preventing the hydrogel fibers from gathering together to form clumps. In this way, the uniformity of the dispersion of the hydrogel fiber in the concrete material can be further greatly improved, so as to further greatly improve the strength and toughness of the produced concrete.

[0024] 7) During the preparation process of the present invention, the solid material, cement, and hydrogel fibers are fully dispersed and stirred in advance using improved equipment before the liquid material is added. During the stirring process of the entire material, the problem of hydrogel fibers clumping due to increased viscosity and friction is effectively overcome, thereby effectively and significantly improving the overall strength and toughness of the produced concrete.

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 separated into a corresponding 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 downwardly provided with corresponding discharge holes. 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 baffles 903 in an annular array.

The outer side of the connector 905 is fixedly connected to a plurality of second baffles 906 in an annular array and arranged in an alternating manner with the first baffles 903. The rotating drive mechanism 10, the drive shaft 902 is rotatably installed to the output shaft end of the first lifting drive mechanism 901, and the rotating 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 goes up to the second partition 906 and abuts against the two adjacent first partitions 903 to form a closure for the discharge hole; during the quantitative unloading process, the drive shaft 902 descends to its position, and the connecting piece 905 goes down to the second partition 906 and leaves, and is spaced apart from the first partition 903, and the rotating drive mechanism 10 drives the drive shaft 902 to rotate, so as to stir and disperse the cement and hydrogel fibers during the unloading process.

[0041] The present invention first improves the design of the cement hopper 7. On the basis of its original weighing function, it is divided into a cement storage chamber 701 and a fiber storage chamber 702, and corresponding discharge holes are respectively provided downward on the bottom sides of the cement storage chamber 701 and the fiber storage chamber 702, and then a cement mixer 9 and a rotating drive mechanism 10 are added.

[0042] The first lifting drive mechanism 901 of the cement mixer 9 drives the driving shaft 902 to rise and fall, and the second lifting drive mechanism 904 drives the connecting member 905 to rise and fall, so as to switch and control the positions of the staggered first partitions 903 and second partitions 906. During the weighing and storing process, the driving shaft 902 is controlled to rise to its position, and the connecting member 905 is controlled to move up to the second partition 906 and respectively abut between two adjacent first partitions 903, so as to form a seal between the discharge holes of the cement storage chamber 701 and the fiber storage chamber 702, thereby facilitating the quantitative weighing of cement and hydrogel fibers. During the quantitative unloading process, the driving shaft 902 is controlled to fall to its position, and the connecting member 905 is controlled to move down to the second partition 906 and away from the first partition 903, so as to facilitate the synchronous output of cement and hydrogel fibers.

[0055] When the liquid material is not added in place, the drive motor 301 can be started to rotate forward, so that the arc-shaped connecting arm 303 and the scraper 304 can scrape the material. At this time, the hydrogel fibers have not absorbed water and do not form obvious adhesions with other materials. Therefore, the raised portion of the rake rod 33 can drive the rake rod 33 to expand outward to rake the material after being subjected to force. Then, the liquid material is added in place and the drive motor 301 is started to reverse, so that the arc-shaped connecting arm 303 and the scraper 304 can shovel and stir the material. At this time, the hydrogel fibers absorb water and form obvious adhesions with other materials, and the rake rod 33 is embedded in the corresponding limiting groove 32 after being subjected to force, thereby preventing the hydrogel fibers from gathering together to form clumps. In this way, the uniformity of the dispersion of the hydrogel fibers in the concrete material can be further greatly improved, thereby further greatly improving the strength and toughness of the produced concrete.

[0056] Example 2: A method for producing high-strength and high-toughness concrete, based on the high-strength and high-toughness concrete production equipment described in the first embodiment, includes the following specific processing steps: S1, the drive shaft 902 rises to its position, the connector 905 ascends to the second partition 906 and abuts between two adjacent first partitions 903 to seal 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; S2, the drive shaft 902 descends into position, the connector 905 descends to the second partition 906 and is separated from the first partition 903, and then the rotary drive mechanism 10 drives the drive shaft 902 to rotate to stir and disperse the cement and hydrogel fibers during the feeding process, so that the cement and hydrogel fibers are evenly introduced into the mixing container 1; At the same time, 600 parts by weight of sand and 150 parts by weight of silica fume are added into the mixing container 1 through the solid material hopper 5; S3, the stirring mechanism 3 is started to mix the cement, hydrogel fiber, sand and silica fume entering the mixing container 1; S4, adding 110 parts by weight of water, 20 parts by weight of a water reducing agent, 40 parts by weight of a high-strength admixture, and 30 parts by weight of a densifying agent into the mixing container 1 through the liquid material hopper 4; S5, the stirring mechanism 3 continues to stir the materials in the mixing container 1 until the materials are stirred and mixed evenly to obtain concrete.

[0057] In this embodiment, the water reducer is an aliphatic high-efficiency water reducer, the high-strength admixture is a high-performance siliceous densifier, and the densifier is FS102 waterproof densifier.

[0058] During the preparation process of the present invention, the solid material, cement and hydrogel fiber are fully dispersed and stirred in advance through the improved equipment, and then the liquid material is added in place. During the stirring process of the entire material, the problem of agglomeration of the hydrogel fiber due to increased viscosity and friction is effectively overcome, thereby effectively and significantly improving the overall strength and toughness of the produced concrete.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
