[0021] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0022] The following describes a dust settling device for concrete production according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0023] like Figure 1-Figure 5 As shown, the concrete production dust settling device according to the embodiment of the present invention may include a settling chamber 10 , a bottom plate assembly 20 and a cleaning assembly 30 .

[0024] Among them, the sedimentation chamber 10 is provided with a dust inlet area 11, a sedimentation area 12 and a cleaning area 13 from top to bottom, wherein the dust inlet area 11 is provided with an entrance 60, the sedimentation area 12 is narrow at the top and wide at the bottom, and the cross-sectional area of ​​the dust inlet area 11 is smaller than the cross-sectional area of ​​the sedimentation area 12; collection ports 70 are opened on both longitudinal sides of the cleaning area 13.

[0025] It is understandable that the dust generated during concrete production can be transferred to the settling chamber 10 through an external vacuum cleaner. The dust first enters the dust inlet area 11 from the inlet 60, then decelerates from the dust inlet area 11 into the settling area 12 and settles in the settling area 12.

[0026] The bottom plate assembly 20 is disposed in the settling area 12 and may include a rectangular frame 21 and a plurality of settling plates 22. The rectangular frame 21 is horizontally disposed and embedded within the settling area 12. The plurality of settling plates 22 are sequentially inserted laterally inside the rectangular frame 21, with adjacent sets of the settling plates 22 sliding against each other. A rotating shaft 23 is provided in the middle of the settling plates 22. The rotating shaft 23 is movably connected to the inner wall of the rectangular frame 21, and one end of each rotating shaft 23 passes through the rectangular frame 21 and is connected to the rotating member 40.

[0027] It should be noted that the rotating member 40 described in this embodiment can simultaneously control the rotation of multiple rotating shafts 23. When adjacent settling plates 22 are tightly against each other, the bottom plate assembly 20 can block the bottom of the settling area 12, so that the dust settles on the top surface of the settling plate 22; when the rotating member 40 controls the settling plate 22 to flip vertically 180 degrees, so that the top and bottom surfaces of the settling plate 22 are exchanged, gaps appear between adjacent settling plates 22. At this time, the settling area 12 is connected with the cleaning area 13 through these gaps. The dust on the settling plate 22 can enter the cleaning area 13 with the settling plate 22 from the corresponding gaps. The cleaning assembly 30 can then perform efficient cleaning operations on the dust in the cleaning area 13, thereby effectively avoiding interference with the air in the settling area 12 during the cleaning process, and at the same time, the normal deposition of dust on the settling plate 22 is not affected.

[0028] The cleaning assembly 30 is longitudinally arranged in the cleaning area 13, and may include a connecting frame 31 and a cleaning roller 33 and two scrapers 32 arranged on the connecting frame 31, wherein the two scrapers 32 are respectively arranged on both sides of the cleaning roller 33, and the scrapers 32 and the cleaning roller 33 are slidably pressed against the bottom of the sedimentation plate 22 through the moving part 50.

[0029] It should be noted that the moving member 50 described in this embodiment can control the scraper 32 and the cleaning roller 33 to move longitudinally synchronously, and can make the cleaning roller 33 rotate while moving, so as to efficiently clean the dust on the sedimentation plate 22.

[0030] Specifically, in the actual process of settling the dust generated during concrete production, the relevant personnel first transfer the dust from the inlet 60 to the settling chamber 10, and the dust can be settled on the top surface of multiple settling plates 22. When the dust on the settling plate 22 needs to be cleaned, the relevant personnel control the settling plate 22 to flip vertically 180 degrees through the rotating part 40, so that the top and bottom surfaces of the settling plate 22 are swapped, so that the dust on the settling plate 22 enters the cleaning area 13. During the process, the dust in the settling area 12 can enter the cleaning area 13 through the corresponding gaps, and when the multiple settling plates 22 re-close the settling area 12, the dust entering the settling area 12 will settle on the top surface of the settling plate 22.

[0031] Subsequently, the relevant personnel can control the scraper 32 and the cleaning roller 33 to move longitudinally synchronously through the movable part 50, and drive the cleaning roller 33 to rotate while it moves, so that the dust on the sedimentation plate 22 and the cleaning area 13 can be discharged from the collection port 70 on one side, and the relevant personnel can collect the discharged dust in a centralized manner at the collection port 70.

[0032] When the settling plate 22 starts rotating again to clean the dust, the operator only needs to control the scraper 32 and cleaning roller 33 to move to the other longitudinal side through the moving member 50, so that the dust can be discharged smoothly from the collection port 70 on the other side. This flexibility greatly reduces the number of steps required to reset the cleaning assembly 30, not only improving the efficiency of the cleaning operation, but also effectively controlling costs.

[0033] In one embodiment of the present invention, Figure 1 、 Figure 3 and Figure 4 As shown, the rotating member 40 may include a longitudinal rack 41 and a plurality of first gears 42 meshing with the longitudinal rack 41, wherein the longitudinal rack 41 is movably provided on the outer wall of the settling chamber 10 via a cylinder 43. The plurality of first gears 42 are respectively provided on corresponding rotating shafts 23.

[0034] Specifically, when relevant personnel need to control the rotation of multiple rotating shafts 23 through the rotating part 40, the cylinder 43 is first started. After the cylinder 43 is started, it can drive the longitudinal rack 41 to move linearly, and the multiple first gears 42 can rotate accordingly with the movement of the longitudinal rack 41, so that the multiple rotating shafts 23 rotate synchronously. By controlling the moving direction and moving distance of the longitudinal rack 41, the rotation angle of the sedimentation plate 22 can be flexibly adjusted.

[0035] In one embodiment of the present invention, Figure 3-Figure 5 As shown, the moving member 50 may include two groups of sub-members respectively arranged on both sides of the cleaning area 13, each group of sub-members including a screw motor 51 and a transverse rack 52, wherein the screw motor 51 is arranged transversely within the cleaning area 13, and the end of the connecting frame 31 is movably connected to the output end of the corresponding screw motor 51. The transverse rack 52 is provided on the inner wall of the cleaning area 13, and the end of the cleaning roller 33 is meshed with the corresponding transverse rack 52 via the second gear 331, and the cleaning roller 33 is movably connected to the connecting frame 31.

[0036] Specifically, when relevant personnel need to control the operation of the cleaning component 30, they start the two screw motors 51, so that the screw motor 51 drives the connecting frame 31 to move horizontally. During the process, the connecting frame 31 drives the scraper 32 and the cleaning roller 33 to move. During the movement of the cleaning roller 33, the second gear 331 thereon moves on the horizontal rack 52, so that the cleaning roller 33 moves and rotates accordingly, so that the cleaning roller 33 can rotate to clean the sedimentation plate 22.

[0037] In summary, the concrete production dust sedimentation device of the embodiment of the present invention can cleverly transfer the dust accumulated on the sedimentation plate to the cleaning room below it through the base plate assembly, so that the cleaning assembly can efficiently clean the dust in the cleaning area, thereby effectively avoiding interference with the air in the sedimentation area during the cleaning process, and at the same time, the normal deposition of dust on the sedimentation plate is not affected.
