Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust removal in mixing stations, in particular to a dust removal device for cement mixing stations. Background Art
[0002] Cement mixing plants are primarily used in cement construction projects, primarily to mix and condition cement. During cement mixing, it's common for cement to be insufficiently mixed. To ensure real-time visibility into the mixing status of the cement in the mixing plant, workers need to open the top of the mixing drum. However, this creates a lot of dust when cement enters the drum, polluting the work environment.
[0003] The document of the existing application publication number CN219705651U discloses a dust removal device for a cement mixing station, comprising a dust removal barrel and a mixing drum, wherein the mixing drum is fixedly installed in the mixing drum; a rotating shaft driven by a motor is rotatably installed in the mixing drum, the lower end of the rotating shaft extends out of the mixing drum and is fixedly connected to a fan blade, and a transmission is also provided between the fan blade and the rotating shaft; the diameter of the dust removal barrel is larger than the diameter of the mixing drum, and a gap is provided between the dust removal barrel and the mixing drum; a filter is provided at the lower end of the side wall of the dust removal barrel; the dust removal device for a cement mixing station drives the fan blade to rotate by the mixing shaft, draws air into the gap between the mixing drum and the dust removal barrel, drives the dust flying in the air to be drawn into the gap, and the drawn air flows out from the filter screen, and the dust remains on the filter screen, which can quickly and effectively remove dust from the environment near the cement mixing station.
[0004] However, this solution still has some shortcomings. In actual use, due to the influence of the height of the mixing drum, the air extraction effect through the rotation of the fan blades is poor, and due to the influence of the filter, dust will overflow upward from the gap, resulting in poor dust removal effect.
[0005] Therefore, it is necessary to provide a dust removal device for a cement mixing station to solve the above technical problems. Utility Model Content
