Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to a raw material screening device for crack-proof fiber concrete. Background Art

[0002] Anti-cracking fiber has good dispersibility and is three-dimensionally distributed in mortar and cement concrete. Due to its outstanding tensile strength, it has a strong pulling effect in concrete or mortar, thus achieving anti-cracking and anti-seepage effects. Anti-cracking fiber uses pure polypropylene as raw material, which can effectively reduce the cracking of concrete and mortar and can be widely used in concrete and mortar waterproofing and anti-seepage projects.

[0003] At present, when filtering the anti-cracking fiber, most of them are directly poured into the filter device for filtering. However, the anti-cracking fiber has strong softness and stickiness, and is not easy to spread on the surface of the filter plate. It will clumpingly adhere to the surface of the filter plate and the inner cavity of the filter device, reducing the filtering effect. Utility Model Content

[0023] The present embodiment is a raw material screening device for concrete. The present embodiment can be installed as a whole in a raw material filtering box body for raw material filtering and processing. A raw material input cylinder can be provided on the top of the present embodiment so that the raw material can be poured in. The mounting bar 11 is a fixing tool and can be installed on the inner box wall of the raw material box body. The filter support frame 12 forms a supporting structure. The filter interval 13 is recessed inwardly to form a filtering space, which is convenient for the raw material to fall into the filtering space and improves the raw material screening effect. The present embodiment uses the filter plate 14 as a filtering tool. The filter plate 14 fits in the spatial structure of the filter interval 13 and is also provided with a dispersing mechanism 16. The dispersing mechanism 16 is provided above the filter plate 14. When the filter plate 14 filters the raw material, it assists in dispersing the raw material, thereby reducing the bonding effect of the anti-cracking fiber, so that the anti-cracking fiber concrete is dispersed before the filtering of the filter plate 14, thereby improving the raw material filtering effect. Embodiment 2:

[0024] See also Figure 1 and Figure 2 , this embodiment is a further optimization of the above embodiment. On the basis of the above embodiment, the filter support frame 12 includes a frame support box 21 and an inner support plate 22. The frame of the inner support plate 22 is bent inward to form a filter section 13. The filter plate 14 includes an arc-shaped filter plate 32 and fixed plates 31 arranged at both ends of the arc-shaped filter plate 32. The fixed plate 31 is fixedly installed on the inner support plate 22 by a fixing bolt 33. The arc-shaped filter plate 32 is bent toward the inner cavity of the filter section 13, and a filter mesh surface 34 is arranged on the arc-shaped filter plate 32.

[0025] The main body of the filter plate 14 includes a fixed plate 31 and an arc-shaped filter plate 32.

The filter mesh surface 34 is designed according to the outer diameter requirements of the filtering operation. The filter plate 14 itself is detachably installed through a fixing bolt 33. The corresponding model of filter plate 14 can be installed according to different filtering requirements. Embodiment three:

The rotation of the operating shaft 51 drives the scattering support plate 52. A hook-shaped block 53 is provided at the top corner of the scattering support plate 52 to form a spiral flipping force. At the same time, it also drives the horizontal flipping plate 61 installed between the hook-shaped blocks 53 to flip, forming a horizontal flipping effect, thereby effectively scattering the anti-cracking fiber, so that the anti-cracking fiber concrete is scattered before filtering by the filter plate 14, and the auxiliary raw material filtration is smoothly implemented.
