Description

Technical Field

[0001] The invention relates to the technical field of building materials, and in particular to a device and method for preparing high-performance fiber-reinforced concrete. Background Art

[0002] High-performance fiber-reinforced concrete is a new type of composite material that significantly enhances the mechanical properties and durability of concrete by uniformly adding high-strength, high-modulus fiber materials to traditional concrete. These fiber materials include but are not limited to steel fibers, glass fibers, polypropylene fibers, etc. They can form an effective support network in concrete, prevent the generation and expansion of cracks, and thus improve the tensile strength, toughness and durability of concrete.

[0003] Generally speaking, in the preparation process of high-performance fiber-reinforced concrete, high-performance fibers need to be continuously added to the concrete for stirring. However, during the stirring process, the high-performance fibers cannot be fully and evenly stirred, which affects the performance of the concrete.

[0004] In summary, how to solve the problem that high-performance fibers cannot be fully mixed and thus the performance of concrete is affected has become a technical problem that technicians in this field need to solve urgently. Therefore, it is necessary to propose a high-performance fiber reinforced concrete preparation device and method. Summary of the invention

[0005] To solve the above problems, the present invention provides a high-performance fiber-reinforced concrete preparation device and method, which drives the ventilation component to introduce gas into the lower chamber through the rotation of the rotating disk, thereby reducing the viscosity of the concrete, promoting the uniform distribution of high-performance fibers in the concrete, and improving the performance of the concrete.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a high-performance fiber-reinforced concrete preparation device, comprising a steel cylinder, a material inlet is opened at the top of the steel cylinder, a material outlet is opened at the bottom of the steel cylinder, a partition plate for dividing the steel cylinder into an upper chamber and a lower chamber is fixedly connected to the inner wall of the steel cylinder, a controller is fixedly connected to the surface of the steel cylinder, a stirring assembly for stirring concrete is arranged in the lower chamber, and an injection port is opened on one side of the lower chamber.

[0007] The upper chamber is provided with a driving component for driving the stirring component, a storage component for storing the high-performance fiber, and a ventilation component for ventilating the stirring component.

[0008] The driving assembly includes a driving member, and a controller is used to control the operation of the driving member. The driving member is fixedly connected to the bottom of the partition plate. The output shaft of the driving member near one end of the partition plate passes through the partition plate and is fixedly connected to a first bevel gear. A rotating disk is provided on the outer sleeve of the first bevel gear.

[0009] The rotating disk is rotatably connected to the top of the partition plate, and a magnetic component for driving the rotating disk to rotate is provided between the rotating disk and the first bevel gear.

[0010] The first bevel gear is meshed with the second bevel gear, and one side of the second bevel gear is fixedly connected with a threaded rod.

[0011] The top of the rotating disk is fixedly connected to a limiting groove, and a threaded rod passes through the limiting groove, extends to the inside of the limiting groove and is rotatably connected to the limiting groove; an adjusting component for adjusting the ventilation volume of the ventilation component is provided on the outer sleeve of the threaded rod, and a control component for controlling the release of high-performance fibers is provided between the adjusting component and the storage component.

[0012] The technical principle of the above scheme is as follows: the driving member is controlled to start by the controller, and the driving member is used to drive the stirring assembly to fully stir the concrete; the first bevel gear is driven to rotate by the driving member, and the rotating disk is driven to rotate by the magnetic assembly, thereby driving the ventilation assembly to pass gas into the concrete in the lower chamber; the rotation of the rotating disk drives the control assembly to release the high-performance fiber in the storage assembly; by closing the magnetic assembly, the first bevel gear controls the ventilation volume of the ventilation assembly through the adjustment assembly.

[0013] The above scheme has the following beneficial effects:

[0014] 1. The present invention can reduce the viscosity of concrete by ventilating the concrete through the ventilation component, which is beneficial to the uniform distribution of high-performance fibers. After the high-performance fibers enter the concrete, the concrete is fully stirred by the stirring component, which is beneficial to improving the stirring efficiency of the concrete and improving the performance of the concrete.

[0015] 2. The present invention can control the release amount of high-performance fibers through storage components and control components, thereby promoting full mixing of high-performance fibers and concrete.

[0016] 3. The present invention adjusts the ventilation volume of the ventilation component through the magnetic component and the adjustment component, thereby reducing the occurrence of concrete stratification caused by excessive ventilation volume.

[0017] Furthermore, the stirring assembly includes a stirring rod, which is fixedly connected to an output shaft of the driving member at one end away from the partition plate, and a plurality of stirring blades are fixedly connected to the stirring rod.

[0018] Beneficial effects: The stirring rod and the stirring blade are directly driven by the output shaft of the driving member, which can ensure that there is a sufficient power source during the stirring process, thereby improving the stirring efficiency of the stirring blade on the concrete and promoting the full mixing of the concrete.

[0019] Furthermore, the storage component includes a storage box, which is fixedly connected to the top wall of the upper chamber, the top of the storage box is connected to the feed port, a first opening is opened at the bottom of the storage box, an infrared sensing solenoid valve is fixedly connected in the first opening, a second opening is opened on the partition plate, and the first opening is connected to the second opening.

[0020] Beneficial effect: The first opening is connected to the second opening, and the high-performance fiber can smoothly pass through the storage box into the lower chamber and be mixed with the concrete, which is beneficial to improving the smoothness and efficiency of the release of the high-performance fiber.

[0021] Furthermore, the control component includes an extension rod, which is fixedly connected to the outer wall of the limiting groove, and one end of the extension rod away from the limiting groove is fixedly connected to an infrared emitter, and the infrared emitter is located below the infrared sensing solenoid valve.

[0022] Beneficial effect: As the rotating disk rotates, when the infrared emitter rotates to the bottom of the infrared sensing solenoid valve, the infrared sensing solenoid valve will receive the infrared emitted by the infrared emitter, thereby opening the infrared sensing solenoid valve, and the high-performance fibers in the storage box will fall into the lower chamber. The high-performance fibers falling into the lower chamber at intervals helps to reduce the agglomeration of the high-performance fibers during the release process. The reduction of agglomeration is conducive to better dispersion of the high-performance fibers in the concrete, thereby improving the performance of the concrete.

[0023] Furthermore, the adjustment assembly includes a sliding block, which is threadedly connected to the outer wall of the threaded rod, and the sliding block slides with the side wall of the limiting groove. The sliding block is hinged with a first connecting rod on the side away from the limiting groove, and the end of the first connecting rod away from the sliding block is hinged with a second connecting rod, and the end of the second connecting rod away from the first connecting rod is fixedly connected to the ventilation assembly.

[0024] Beneficial effect: The sliding block is threadedly connected to the outer wall of the threaded rod. When the second bevel gear rotates, it can drive the sliding block to move up and down along the threaded rod. As the sliding block slides, the first connecting rod and the second connecting rod are hinged. At this time, the ventilation assembly can change the ventilation volume as the position of the second connecting rod changes.

[0025] Furthermore, the ventilation assembly includes a piston head and a piston cylinder, the piston head is fixedly connected to an end of the second connecting rod away from the first connecting rod, the piston cylinder is fixedly connected to the inner wall of the upper chamber, and the piston head is slidably matched with the inner wall of the piston cylinder.

[0026] An air inlet and an air outlet are provided on one side of the piston cylinder away from the piston head. The air outlet is fixedly connected to an air pipeline, which passes through the partition plate and extends into the lower chamber. Both the air inlet and the air outlet are fixedly connected to a one-way valve.

[0027] Beneficial effects: The piston head and the inner wall of the piston cylinder are slidably matched. This design allows the piston head to move freely in the piston cylinder, thereby accurately controlling the flow rate of the airflow. The air inlet and the air outlet are fixedly connected with a one-way valve. This design ensures that the airflow can only pass in one direction, preventing backflow or leakage of the airflow.

[0028] Furthermore, the magnetic assembly includes a plurality of electromagnets, which are all fixedly connected to the rotating disk, and the controller is used to control the opening and closing of the electromagnets.

[0029] Beneficial effect: The opening and closing of the electromagnet can be precisely controlled by the controller, so that the rotation of the rotating disk can be controlled. When the electromagnet is closed, the self-rotation of the second bevel gear will drive the adjustment component to operate, thereby realizing precise adjustment of the ventilation volume of the ventilation component.

[0030] Furthermore, a protective shell for protecting the driving component is fixedly connected to the bottom of the partition plate.

[0031] Beneficial effect: The protective shell can protect the driving part. During the process of mixing concrete with the stirring rod and the stirring blade, the impact of the concrete on the driving part can be reduced, thereby increasing the service life of the driving part.

[0032] Furthermore, a pressure sensor for monitoring the remaining amount of high-performance fibers is fixedly connected to the bottom wall of the storage box, and the controller is used to receive pressure data monitored by the pressure sensor.

[0033] Beneficial effects: The pressure sensor can monitor in real time the pressure exerted by the high-performance fibers in the storage box on the bottom wall of the storage box. By accurately sensing this pressure data, the remaining amount of the high-performance fibers can be known, which is conducive to the staff to replenish the high-performance fibers in time.

[0034] Furthermore, a method for preparing high-performance fiber-reinforced concrete comprises the following steps:

[0035] Step 1: Add high-performance fiber into the storage box through the feed port.

[0036] Step 2: Inject concrete into the lower chamber through the injection port.

[0037] Step 3: Start the driving member and use the driving member to drive the stirring rod and the stirring blade to rotate.

[0038] Step 4: By starting the electromagnet, the first bevel gear drives the rotating disk to rotate, and the infrared sensing solenoid valve contacts the infrared emitter. The infrared sensing solenoid valve will open after receiving the infrared rays emitted by the infrared emitter, and the high-performance fiber in the storage box will be released into the lower chamber through the first opening.

[0039] Step 5: The piston head is pushed to perform piston motion in the piston cylinder by rotating the rotating disk to ventilate the lower chamber.

[0040] Step 6: Turn off the electromagnet, adjust the position of the sliding block through the first bevel gear, control the reciprocating distance of the piston head, and adjust the ventilation volume.

[0041] Step 7: After mixing is completed, the concrete is discharged through the discharge port for use.

[0042] Beneficial effect: The infrared induction solenoid valve senses infrared rays to release high-performance fibers into the lower chamber, and the driving member is started to drive the stirring rod and stirring blades to rotate, thereby promoting the mixing of concrete and high-performance fibers and improving the mechanical properties of concrete.

[0043] By starting the electromagnet, the first bevel gear drives the rotating disk to rotate, and then pushes the piston head to perform piston movement in the piston cylinder, thereby achieving ventilation and stirring of the concrete in the lower chamber, and further promoting the full mixing of the concrete and the high-performance fiber.

[0044] The ventilation volume can be controlled by adjusting the position of the sliding block. Accurate ventilation volume control is beneficial to reducing the occurrence of concrete stratification during the ventilation process.

[0045] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0052] The following is further described in detail through specific implementation methods:

[0053] Embodiment 1:

[0054] As attached Figure 1-Figure 4 As shown: A high-performance fiber reinforced concrete preparation device includes a steel cylinder 1, a material inlet 2 is opened at the top of the steel cylinder 1, a material outlet 24 is opened at the bottom of the steel cylinder 1, a partition plate 22 for dividing the steel cylinder 1 into an upper chamber and a lower chamber is fixedly connected to the inner wall of the steel cylinder 1 by bolts, a controller 3 is fixedly connected to the surface of the steel cylinder 1 by screws, a stirring assembly for stirring concrete is arranged in the lower chamber, and an injection port 4 is opened on one side of the lower chamber.

[0055] The upper chamber is provided with a driving component for driving the stirring component, a storage component for storing the high-performance fiber, and a ventilation component for ventilating the stirring component.

[0056] The driving assembly includes a driving member. In this embodiment, the driving member is selected as a double-headed motor 9. The controller 3 is used to control the operation of the double-headed motor 9. The double-headed motor 9 is bolted and fixedly connected to the bottom of the partition plate 22. The output shaft of the double-headed motor 9 near one end of the partition plate 22 passes through the partition plate 22 and is bolted and fixedly connected to the first bevel gear 12. The outer cover of the first bevel gear 12 is provided with a rotating disk 8.

[0057] The rotating disk 8 is rotatably connected to the top of the partition plate 22 , and a magnetic component for driving the rotating disk 8 to rotate is provided between the rotating disk 8 and the first bevel gear 12 .

[0058] The first bevel gear 12 is meshed with the second bevel gear 13 , and a threaded rod 18 is fixedly connected to one side of the second bevel gear 13 by screws.

[0059] The top of the rotating disk 8 is fixedly connected to the limiting groove 7 by bolts, and the threaded rod 18 penetrates the limiting groove 7, extends to the inside of the limiting groove 7 and is rotatably connected to the limiting groove 7; an adjusting component for adjusting the ventilation volume of the ventilation component is disposed on the outer sleeve of the threaded rod 18, and a control component for controlling the release of high-performance fibers is disposed between the adjusting component and the storage component.

[0060] like Figure 3 As shown, the stirring assembly includes a stirring rod 10, which is bolted and fixedly connected to the output shaft of the double-headed motor 9 at one end away from the partition plate 22, and a plurality of stirring blades 11 are bolted and fixedly connected to the stirring rod 10.

[0061] Combination Figure 2 As shown, the storage assembly includes a storage box 5, which is bolted and fixedly connected to the top wall of the upper chamber. The top of the storage box 5 is connected to the feed port 2. A first opening 19 is provided at the bottom of the storage box 5. An infrared sensing solenoid valve is screwed in the first opening 19. A second opening 23 is provided on the partition plate 22. The first opening 19 is connected to the second opening 23.

[0062] The control component includes an extension rod 6, which is fixedly connected to the outer wall of the limiting groove 7 by screws. The end of the extension rod 6 away from the limiting groove 7 is fixedly connected to the infrared emitter 21 by screws. The infrared emitter 21 is located below the infrared sensing solenoid valve.

[0063] The adjustment assembly includes a sliding block 14, which is threadedly connected to the outer wall of the threaded rod 18. The sliding block 14 slides with the side wall of the limiting groove 7. The sliding block 14 is hinged with a first connecting rod 17 on the side away from the limiting groove 7. The end of the first connecting rod 17 away from the sliding block 14 is hinged with a second connecting rod 16. The end of the second connecting rod 16 away from the first connecting rod 17 is fixedly connected to the ventilation assembly with bolts.

[0064] like Figure 4 As shown, the ventilation assembly includes a piston head 25 and a piston cylinder 15. The piston head 25 is bolted to the end of the second connecting rod 16 away from the first connecting rod 17. The piston cylinder 15 is bolted to the inner wall of the upper chamber. The piston head 25 is slidably matched with the inner wall of the piston cylinder 15.

[0065] The piston cylinder 15 has an air inlet and an air outlet on one side away from the piston head 25. The air outlet is fixedly connected to an air pipeline 26 by screws. The air pipeline 26 passes through the partition plate 22 and extends into the lower chamber. Both the air inlet and the air outlet are fixedly connected to a one-way valve by screws.

[0066] like Figure 2 As shown, the magnetic assembly includes a plurality of electromagnets 27 , and the electromagnets 27 are all screw-fixedly connected to the rotating disk 8 , and the controller 3 is used to control the opening and closing of the electromagnets 27 .

[0067] The specific implementation process is as follows: Figure 1 and Figure 2For example, first, the staff can inject concrete into the lower chamber through the injection port 4, and at the same time put the high-performance fiber into the storage box 5 through the feed port 2. Then the staff can start the double-headed motor 9 through the controller 3. When the double-headed motor 9 rotates, it will drive the stirring rod 10 and the stirring blade 11 to rotate, and the concrete in the lower chamber is stirred by the stirring rod 10 and the stirring blade 11.

[0068] Combination Figure 3 As shown, as the double-headed motor 9 is started, the double-headed motor 9 will drive the first bevel gear 12 to rotate. When the staff starts the electromagnet 27 through the controller 3, the first bevel gear 12 will drive the rotating disk 8 to rotate together by utilizing the magnetic attraction of the electromagnet 27.

[0069] As the rotating disk 8 rotates, the second bevel gear 13 rotates with the rotating disk 8. At this time, the second bevel gear 13 revolves around the first bevel gear 12, and at this time, the second bevel gear 13 does not rotate, and the sliding rod 14 does not slide along the limiting groove 7.

[0070] When the rotating disk 8 rotates, the rotating disk 8 drives the extension rod 6 on the limit slot 7 to rotate together. When the infrared emitter 21 on the extension rod 6 rotates to the bottom of the infrared sensing solenoid valve, the infrared sensing solenoid valve receives the infrared rays emitted by the infrared emitter 21. At this time, the infrared sensing solenoid valve will open, and the high-performance fibers in the storage box 5 will enter the lower chamber through the first opening 19 and the second opening 23 to be mixed with the concrete. When the infrared emitter 21 is away from the position of the infrared sensing solenoid valve, the infrared sensing solenoid valve will close, and the high-performance fibers in the storage box 5 will not be released through the infrared sensing solenoid valve.

[0071] As the stirring rod 10 and the stirring blade 11 stir the concrete and the high-performance fibers, the stirring blade 11 can drive the high-performance fibers to move in the concrete, so that the high-performance fibers can be dispersed in the concrete, reducing the agglomeration of the high-performance fibers.

[0072] As the rotating disk 8 rotates, the sliding block 14 in the limiting groove 7 will also rotate with the rotation of the rotating disk 8. At this time, the rotation of the sliding block 14 will drive the first connecting rod 17 to reciprocate. Because the first connecting rod 17 is hinged to the second connecting rod 16, the second connecting rod 16 will drive the piston head 25 to perform piston movement along a straight line in the piston cylinder 15.

[0073] Combination Figure 4 As shown, when the piston head 25 moves to the left, the gas will enter the piston cylinder 15 through the one-way valve at the air inlet. When the piston head 25 moves to the right, the gas in the piston cylinder 15 will enter the lower chamber through the one-way valve at the air outlet, assisting the stirring rod 10 and the stirring blades 11 to stir the concrete and the high-performance fiber.

[0074] By ventilating the concrete, the viscosity of the concrete can be reduced and the fluidity of the concrete can be increased, so that the high-performance fibers in the concrete can be fully mixed and evenly distributed in the concrete, thereby improving the mechanical properties of the concrete.

[0075] Combination Figure 3 As shown, when the ventilation volume in the concrete is too large, the staff can control the electromagnet 27 to be closed through the controller 3. When the electromagnet 27 is closed, the rotation of the first bevel gear 12 will not drive the rotating disk 8 to rotate. At this time, as the first bevel gear 12 rotates, the second bevel gear 13 will rotate, and the rotation of the second bevel gear 13 will drive the threaded rod 18 to rotate. Since the rotating disk 8 stops rotating, the sliding block 14 will slide along the limiting groove 7 driven by the threaded rod 18. When the sliding block 14 slides to the side close to the second bevel gear 13, since the sliding block 14 is close to the center of the rotating disk 8, the movement range of the first connecting rod 17 will be reduced. At this time, driven by the first connecting rod 17, the movement range of the second connecting rod 16 and the piston head 25 will also be reduced accordingly. At this time, the gas released by the piston cylinder 15 will be reduced, thereby reducing the ventilation volume in the concrete, thereby better improving the performance of the concrete.

[0076] When the concrete mixing is completed, the staff can discharge the concrete through the discharge port 24 for use.

[0077] Embodiment 2:

[0078] The difference from the above embodiment is that a protective shell for protecting the double-headed motor 9 is fixedly connected to the bottom of the partition plate 22 by screws.

[0079] The specific implementation process is as follows: the protection of the double-headed motor 9 by the protective shell can effectively reduce the occurrence of concrete splashing into the double-headed motor 9 during the mixing process, thereby helping to extend the service life of the double-headed motor 9.

[0080] Embodiment 3:

[0081] like Figure 2 As shown, the difference from the above embodiment is that a pressure sensor 20 for monitoring the remaining amount of high-performance fibers is fixedly connected to the bottom wall of the storage box 5 by screws, and the controller 3 is used to receive pressure data monitored by the pressure sensor 20.

[0082] The specific implementation process is as follows: the pressure of the remaining high-performance fibers in the storage box 5 can be monitored through the pressure sensor 20, and the staff can preset the minimum pressure of the high-performance fibers in the storage box 5 in the controller 3. As the high-performance fibers in the storage box 5 are continuously consumed, the pressure of the high-performance fibers on the pressure sensor 20 will gradually decrease. When the controller 3 determines that the pressure of the high-performance fibers in the storage box 5 on the pressure sensor 20 is less than the preset value, the controller 3 will monitor this pressure change and then remind the staff to replenish the high-performance fibers.

[0083] Embodiment 4:

[0084] like Figure 5 As shown, a method for preparing high-performance fiber-reinforced concrete comprises the following steps:

[0085] Step 1: Add high-performance fibers into the storage box 5 through the feed port 2.

[0086] Step 2: inject concrete into the lower chamber through the injection port 4.

[0087] Step 3: Start the double-headed motor 9, and use the double-headed motor 9 to drive the stirring rod 10 and the stirring blade 11 to rotate.

[0088] Step 4: By starting the electromagnet 27, the first bevel gear 12 drives the rotating disk 8 to rotate, and the infrared sensing solenoid valve contacts the infrared emitter 21. The infrared sensing solenoid valve will open after receiving the infrared rays emitted by the infrared emitter 21, and the high-performance fibers in the storage box 5 will be released into the lower chamber through the first opening 19.

[0089] Step 5: The piston head 25 is pushed to perform piston motion in the piston cylinder 15 by rotating the rotating disk 8 to ventilate the lower chamber.

[0090] Step 6: Turn off the electromagnet 27, adjust the position of the sliding block 14 through the first bevel gear 12, control the reciprocating distance of the piston head 25, and adjust the ventilation volume.

[0091] Step 7: After the mixing is completed, the concrete is discharged through the discharge port 24 for use.

[0092] The specific implementation process is as follows:

[0093] The high-performance fiber is placed into the storage box 5 through the feed port 2, and the concrete is injected into the lower chamber through the injection port 4; then the double-headed motor 9 is started by the controller 3, and the double-headed motor 9 is used to drive the stirring rod 10 and the stirring blade 11 to rotate, thereby stirring the concrete.

[0094] The electromagnet 27 is activated by the controller 3, and the rotating disk 8 is driven to rotate while the first bevel gear 12 rotates. At this time, the infrared sensing solenoid valve senses the infrared rays emitted by the infrared emitter 21 and adds high-performance fibers to the concrete. At the same time, as the rotating disk 8 rotates, the rotating disk 8 drives the first connecting rod 17 and the second connecting rod 16 to reciprocate. At this time, the piston head 25 performs piston motion in the piston cylinder 15, and the gas in the piston cylinder 15 is passed into the concrete, which helps the concrete and the high-performance fibers to be further stirred.

[0095] When the ventilation volume needs to be adjusted, the electromagnet 27 can be turned off, and the first bevel gear 12 can be used to drive the second bevel gear 13 to rotate. The position of the sliding block 14 is adjusted by the rotation of the second bevel gear 13, thereby changing the movement distance of the first connecting rod 17 and further changing the ventilation volume of the piston cylinder 15 on the concrete.

[0096] After the concrete mixing is completed, the staff can discharge the mixed concrete through the discharge port 24 for final use.

[0097] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
