Description

Technical Field

[0001] The present invention relates to the technical field of mixing devices, and particularly to a fiber concrete mixing device. Background Art

[0002] Fiber concrete is a composite material formed by incorporating an appropriate amount of fiber materials into ordinary concrete. Due to its significantly improved crack resistance, toughness, and durability, it is widely used in engineering fields such as construction, roads, and bridges. For example, a fiber mixture formed by mixing synthetic fiber material and concrete in a weight ratio of 0.5%:1 is favored for its good comprehensive performance. Before mixing, the synthetic fibers need to be soaked to make them fully absorb water and reach a saturated state, so as to effectively enhance the bonding force between the fibers and the concrete matrix and ensure the overall performance stability of the fiber concrete.

[0003] However, most of the existing fiber concrete mixing devices currently do not fully consider this key link of fiber soaking treatment. Some devices directly put in synthetic fibers that have not been fully soaked during the mixing process, resulting in uneven dispersion of the fibers in the concrete and difficult full bonding with the concrete, seriously affecting the mechanical properties of the fiber concrete. There are also some devices that have a soaking process, but the soaking and mixing links are independent of each other. This not only makes the operation cumbersome and inefficient, but also easily causes fiber loss and secondary pollution during the transfer process, and cannot meet the requirements of actual projects for high-quality and high-efficiency production of fiber concrete.

[0004] Therefore, there is an urgent need to develop a device that can integrate fiber soaking treatment and efficient mixing of concrete to ensure the production quality and efficiency of fiber concrete. In view of this, we propose a fiber concrete mixing device. Summary of the Invention

[0040] The following will describe clearly and completely the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention

[0041] Please refer to Figures 1-9 , the above technical solutions are described in detail by the following embodiments of the present invention

[0042] In this embodiment, the fiber concrete mixing device, as shown in Figure 1 and Figure 2 , the mixing material bin 1 is used to input aggregates and powders through the concrete feeding port 101. Specifically, it further includes

[0043] Fiber soaking feeding part, as shown in the positional relationship in Figure 1 and Figure 2 , including the soaking hopper 2 installed on the mixing material bin 1 in a conductive manner. The main purpose of the soaking hopper 2 is to soak the fibers and then input them into the mixing material bin 1, and wash the drained fibers into the mixing material bin 1 through the flushing action, and realize quantitative water supply and then mixing, so as to avoid the problem of unstable moisture content caused by directly mixing fibers and quantitative water

[0044] As shown in Figures 3-6 , a carrier assembly 3 is installed in the soaking hopper 2 by the lifting cylinder 4. Specifically, in order to obtain the functions of soaking fibers and fishing out and removing the excess moisture of the fibers, a vertical partition plate 22 is fixedly connected in the soaking hopper 2. The two sides of the vertical partition plate 22 are respectively divided into a soaking chamber 201 and a flushing chamber 202. A bottom plate 21 is fixedly connected between the bottom wall of the soaking chamber 201 and the bottom end of the vertical partition plate 22, so that the fibers can be soaked in the soaking chamber 201 and lifted by the carrier assembly 3

[0045] It should be noted that in order to better agglomerate the fibers after soaking and make them approach the input amount and pour them into the shower chamber 202, the carrier assembly 3 of this embodiment includes a filter plate 31 with a structure as shown in Figures 5-9 At the right end of the filter plate 31, there is a recessed plate 311. In this embodiment, the filter plate 31 of the plate body is arranged at an 80° angle with the vertical partition plate 22, so that during the rising process of the plate body, the fibers can flow to the recessed plate 311 at the bottom end along with the water flow and the decrease of the liquid level height. In other embodiments, 60° or 75° can be designed. If the inclination angle is too large, the fibers will accumulate prematurely, which is not conducive to improving the soaking efficiency and the dispersion effect.

[0046] In this embodiment, a turning plate 32 is rotatably installed at the recessed plate 311 of the filter plate 31. In order to maintain the effect of the turning plate 32 turning outwards towards the shower chamber 202, a torsion spring groove 3101 as shown in Figure 9 is provided at the rotation connection end of the filter plate 31 and the turning plate 32. A torsion spring body 36 is installed in the torsion spring groove 3101. Based on the elasticity of the two torsion arms of the torsion spring body 36 outwards and the relative fixation of the filter plate 31 itself, the turning plate 32 can be kept with an elastic acting force for turning outwards; and the turning plate 32 includes an inner attachment plate 321 and a vertical baffle plate 322 which are provided with a position retention groove 302 and have a V-shaped structure. In this embodiment, only the filter plate 31 and the inner attachment plate 321 are provided with filter holes 301. The vertical baffle plate 322 mainly maintains two stroke states as shown in Figure 5 and Figure 6 during the lifting process, that is, when soaking the fibers, the inner attachment plate 321 and the vertical baffle plate 322 are used to fit on the plate surfaces of the filter plate 31 and the vertical partition plate 22 respectively; when reaching the top end of the vertical partition plate 22, the turning plate 32 turns the concentrated fibers into the shower chamber 202. Figure 5 and Figure 6 In this embodiment, a U-shaped connecting rod 33 is fixedly connected to one end of the filter plate 31 away from the turning plate 32. The U-shaped connecting rod 33 is inserted into the wall of the soaking hopper 2 and is connected to the output shaft of the lifting cylinder 4 through a fixedly connected horizontal connecting plate 34. The lifting of the carrier assembly 3 is realized by the lifting of the lifting cylinder 4; a support plate 35 is horizontally connected to the U-shaped connecting rod 33 inside the soaking chamber 201. A material discharging port 351 is provided on the support plate 35 for installing the fiber hopper 5; in order to improve the fiber soaking efficiency and uniformity, a transmission belt 7 is rotatably installed on the support plate 35 through a stirring motor 6. Stirring blades 8 are installed at the axles of the transmission wheels at both ends of the transmission belt 7. The distance between the stirring blades 8 and the plate body is fixed and there will be no conflict during the lifting process.

[0047] In this embodiment, a U-shaped connecting rod 33 is fixedly connected to one end of the filter plate 31 away from the turning plate 32. The U-shaped connecting rod 33 is inserted into the wall of the soaking hopper 2 and is connected to the output shaft of the lifting cylinder 4 through a fixedly connected horizontal connecting plate 34. The lifting of the carrier assembly 3 is realized by the lifting of the lifting cylinder 4; a support plate 35 is horizontally connected to the U-shaped connecting rod 33 inside the soaking chamber 201. A material discharging port 351 is provided on the support plate 35 for installing the fiber hopper 5; in order to improve the fiber soaking efficiency and uniformity, a transmission belt 7 is rotatably installed on the support plate 35 through a stirring motor 6. Stirring blades 8 are installed at the axles of the transmission wheels at both ends of the transmission belt 7. The distance between the stirring blades 8 and the plate body is fixed and there will be no conflict during the lifting process.

[0048] Considering the need to avoid the situation where drained fibers adhere to the turning plate 32, in this embodiment, a spray head 9 is installed above the soaking hopper 2 located in the shower cavity 202. The spray head 9 can supply water for the concrete and provide a water flow for flushing, so that the fibers on the turning plate 32 are fully flushed off, realizing the combination of accurate metering of the water for concrete mixing and the fibers.

[0049] In order to better monitor the turning situation of the turning plate 32 in this embodiment, as Figure 5 and Figure 6 the positional relationship, an infrared induction switch 10 is installed at the soaking hopper 2 located on the outward turning path of the turning plate 32 to judge whether the fibers are effectively turned out and retracted, so as to ensure the reliable soaking of the fibers and their pouring into the shower cavity 202.
