Description

Technical Field

[0001] The present invention relates to the technical field of steel fibers, in particular to a steel fiber dispersing device. Background Art

[0002] As a composite material, steel fiber can effectively hinder the expansion and formation of concrete cracks, and can significantly improve the tensile, bending, impact and fatigue resistance of concrete, and has good ductility. In the process of mass production of high-strength steel fiber composite concrete, a large amount of steel fibers are required. The steel fibers are required to be magnetized during transportation so that the steel fibers can be tightly arranged. In order to improve the uniformity of steel fiber distribution in steel fiber concrete, the tightly arranged steel fibers need to be broken up for standby before mixing with concrete. In the prior art, in order to disperse the steel fibers, the dispersion device usually uses a shaking method to shake the piled steel fibers so that the steel fibers are dispersed and fall through the screen or partition. However, when the steel fibers are densely clustered, this method is not conducive to the dispersion of the steel fibers, which will result in poor dispersion of the steel fibers. Summary of the Invention

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] Please refer to Figures 1 to 5 An embodiment of the present invention provides a steel fiber dispersion device. Steel fibers are fibers having an aspect ratio (the ratio of fiber length to its diameter; when the fiber cross-section is non-circular, the diameter is converted to the equivalent cross-sectional circular area) of 40 to 80, produced by cutting fine steel wire, shearing cold-rolled strip, milling steel ingots, or rapid condensation of molten steel. The steel fibers are uniformly mixed with concrete. The mixed steel fiber concrete has better adhesion, compressive strength, and toughness, and also improves the reverse osmosis performance of the concrete, making the building more stable. However, the steel fibers are closely arranged due to magnetization during transportation. Before the steel fibers are mixed with concrete, the dispersion device of the present application is needed to break up the closely arranged steel fibers due to magnetization so that they can be evenly mixed with the concrete after dispersion.

[0037] The steel fiber dispersing device of the present application includes a dispersing box 1, multiple sets of swinging mechanisms 2, a breaking mechanism 3, a bracket 4 and a vibrating bucket 5; wherein the dispersing box 1 is installed on the bracket 4, and the bracket 4 supports the dispersing box 1 so that the dispersing box 1 has a certain height distance from the ground, and the top of the dispersing box 1 is provided with an open mouth, and one side of the top surface of the dispersing box 1 is provided with an inclined surface, and the inclined direction is inclined downward along the side close to the dispersing box 1, and a feed port 11 is provided thereat for pouring the steel fiber to be dispersed therefrom, and a discharge port 12 is provided at the bottom of the dispersing box 1, and the preliminarily dispersed steel fiber falls from the discharge port 12; multiple sets of swinging mechanisms 2 are provided in the dispersing box 1 The first supporting rod 211 of each group of swing rollers 21 is also arranged in the horizontal direction, and the adjacent first supporting rods 211 between the two groups of swing rollers 21 are arranged crosswise. Since the steel fibers to be dispersed have magnetism and attract each other, when the two sets of swing rollers 21 are stationary, the steel fibers to be dispersed will not fall from the gap at the intersection, and the steel fibers are supported by the two sets of swing mechanisms 2; one end of each set of swing rollers 21 is connected to a driving member 22, which is installed on the bracket 4. When the driving member 22 is started, the driving member 22 can drive the swing member 21 to rotate back and forth in the clockwise and counterclockwise directions, and the rotation amplitude is small, driving the first support rod 211 to move up and down. The rotation of the two sets of swing members 21 causes the steel fibers accumulated thereon to receive the force, thereby being pulled from the first support rod 211. The steel fibers fall into the gaps between the two ends of the concrete; the scattering mechanism 3 is arranged just below the discharge port 12, and its length direction is the same as the length direction of the swing roller 21. When the steel fibers fall from the swing roller 21, they pass through the discharge port 12 and fall onto the scattering mechanism 3. The scattering mechanism 3 is started to rotate, and the fallen steel fibers can be further scattered; the vibrating bucket 5 is arranged below the scattering mechanism 3, and is arranged in an inclined state. The steel fibers scattered by the scattering mechanism 3 fall onto the vibrating bucket 5 and then fall along the inclined direction. A storage trolley or storage box can be set below the lowest end of the vibrating bucket 5 to collect the dispersed steel fibers and then pour them into the concrete.

[0038] In some embodiments, the swing mechanism 2 can be arranged in three or four groups in parallel along the horizontal direction, so that the first support rods 211 of two adjacent groups of swing rollers 21 are arranged crosswise to support the steel fibers; one end of each group of swing rollers 21 is connected to a driving member 22, and the swing rollers 21 are driven to rotate by the above method to control the falling of the steel fiber discharge port.

[0039] In a preferred embodiment, if Figure 1 As shown, a bracket 4 is also included, and the dispersion box 1 is installed on the bracket 4.

[0040] In a preferred embodiment, if Figure 2 and Figure 4 As shown, the driving member 22 includes a mounting frame 221, a first motor 222, a first connecting shaft 223 and a second connecting shaft 224. The mounting frame 221 is arranged on the bracket 4, and the first motor 222 is arranged on the mounting frame 221. The output end of the first motor 222 is fixedly sleeved with a disc 225. One end of the first connecting shaft 223 is fixedly connected to the surface of the disc 225, and the other end is rotatably connected to one end of the second connecting shaft 224. The other end of the second connecting shaft 224 is fixedly connected to one end of the swing roller 21. The rotation of the first motor 222 is used to drive the swing roller 21 to rotate.

[0041] In this embodiment, the output end of the first motor 222 is fixedly sleeved with a disc 225, the first connecting shaft 223 and the second connecting shaft 224 are both rigid connectors, and the connection point between the two is a rotational connection, the first connecting shaft 223, the second connecting shaft 224 and the disc 225 are all in the same plane, and one end of the first connecting shaft 223 is fixedly connected to the surface of the disc 225 close to the extension; when the steel fiber to be dispersed is placed in the dispersion box 1, the first motor 222 is started, and the output end of the first motor 222 rotates to drive the disc 225 fixedly sleeved therewith to make a circular motion, and the disc 255 rotates to drive one end of the first connecting shaft 223 fixedly connected thereto to make a circular motion with the disc 225. The other end of the first connecting shaft 223 is rotatably connected to one end of the second connecting shaft 224, and the other end of the second connecting shaft 224 is fixedly connected to one end of the swing roller 21, so that when one end of the first connecting shaft 223 makes a circular motion, the other end of the first connecting shaft 223 can only make an arc-shaped motion with the second connecting shaft 224 as the axis length radius and the end part of the second connecting shaft 224 and the swing roller 21 as the center of the circle, driving the second connecting shaft 224 to swing along the same trajectory, and then driving the swing roller 21 fixedly connected to the second connecting shaft 224 to rotate back and forth in the arc direction, so that the first support rod 211 connected to the swing roller 21 swings up and down, causing the steel fiber supported above it to fall.

[0042] In a preferred embodiment, if Figure 2 As shown, the breaking up mechanism 3 includes a rotating roller 31 and a second motor 32. The rotating roller 31 is arranged directly below the discharge port 12. Its length direction is consistent with the length direction of the swing roller 21, and multiple groups of breaking up rods 311 are evenly arranged around it. One end of the rotating roller 31 is rotatably connected to the mounting part on the bracket 4, and the other end is fixedly connected to the output end of the second motor 32, which is used to drive the rotating roller 31 to rotate.

[0043] In this embodiment, the rotating roller 31 is cylindrical and is arranged just below the feeding port 12. A plurality of groups of breaking rods 311 are evenly arranged on the rotating roller along its circumference. Adjacent breaking rods 311 are staggered with each other, thereby improving the breaking effect of the steel fibers. A mounting member is fixedly provided on the bracket 4 by bolts, and one end of the rotating roller 31 is rotatably connected to the mounting member. The other end of the rotating roller 31 is fixedly connected to the output end of the second motor 32.

[0044] Start the second motor 32, and the second motor 32 rotates to drive the rotating roller 31 fixedly connected to it to rotate. When the rotating roller 31 rotates, the breaking rod 311 thereon contacts the steel fibers falling from the discharge port 12. The steel fibers are further broken up by the rotation of the breaking rod 311, thereby improving the dispersion effect of the steel fibers.

[0045] In a preferred embodiment, if Figure 3 and Figure 5 As shown, a support member 13 is symmetrically arranged in the dispersion box 1, and the support member 13 is connected to the inner wall of the dispersion box 1. A plurality of groups of second support rods 131 are evenly arranged along the length direction of the support member 13. The second support rods 131 and the first support rods 211 of the adjacent swing roller 21 are cross-arranged to support the steel fibers to be dispersed in the dispersion box 1.

[0046] In this embodiment, support members 13 are symmetrically arranged on the inner wall of the dispersion box 1 about the swing roller 21. The length direction of the support members 13 is consistent with the length direction of the swing roller 21, and is fixedly connected to the inner wall of the dispersion box 1 by bolts. The support members 13 are evenly provided with multiple groups of second support rods 131 along their length direction. The second support rods 131 are all cylindrical structures and have a certain inclination angle. The second support rods 131 and the first support rods 211 adjacent to them are arranged to cross each other. The gap at the intersection position causes the steel fibers to fall when the swing roller 21 swings. When the swing roller 21 is stationary, the support members 13 and the swing member 21 cooperate with each other to support the steel fibers to be dispersed.

[0047] In a preferred embodiment, if Figure 1 and Figure 2 As shown, a vibrating bucket 5 is provided below the scattering mechanism 3. One end of the vibrating bucket 5 is fixedly connected to the bracket 4, and the other end is connected to the bracket 4 via a suspension member 51. The vibrating bucket 5 is arranged downwardly and tilted along the side close to the suspension member 51. Preferably, the suspension member 51 includes a telescopic tube 511 and a spring 512, and the spring 512 is sleeved within the telescopic tube 511. Preferably, a vibration motor 52 is provided at the bottom of the vibrating bucket 5.

[0048] In this embodiment, the steel fibers scattered by the breaking mechanism 3 fall on the vibrating bucket 5. One end of the vibrating bucket 5 is fixedly connected to the bracket 4, and the other end is suspended and fixed by a suspension member 51. The suspension member 51 can be made of other elastic materials. The telescopic tube 511 and spring 512 of the present application can make the vibrating bucket 5 have a certain inclination angle, but the elasticity of the spring 512 ensures that the vibrating bucket 5 and the hanging end of the spring 512 always have a certain height from the ground, which is convenient for setting a trolley under the hanging end to store the scattered steel fibers; when the suspension member 51 is used to fix the vibrating bucket 5, the inclination angle of the vibrating bucket 5 is adjustable as the steel fibers thereon slide, which facilitates the sliding of the steel fibers; a vibration motor 52 is provided at the bottom of the vibrating bucket 5, which increases the shaking of the vibrating bucket 5 and improves the sliding speed of the steel fibers on the vibrating bucket 5.
