Limestone dust collection and treatment equipment

Abstract

The invention discloses limestone dust collection and treatment equipment, which comprises a dust bin, a spraying mechanism, a grinding device, a precipitation bin, a dehydration mechanism and a granulation mechanism, wherein the spraying mechanism comprises a spraying bin and a spraying assembly arranged above the spraying bin, the spraying bin is connected with the dust bin through a dust suction pipe, the grinding device comprises a heat transfer guide plate arranged on the dust suction pipe and a grinding wheel arranged on the heat transfer guide plate, the precipitation bin comprises a clear liquid part and a precipitation part, a liquid in the clear liquid part is connected with the spraying assembly through a first pipeline, the feed port of the drying oven of the dehydration mechanism is connected with the discharge port of the precipitation part through a second pipeline, the drying oven exchanges heat with the heat transfer guide plate through a third pipeline, the granulation mechanism comprises a ramming disc, ramming hammers and a drying and cutting disc, a plurality of ramming cylinders are annularly arrayed on the ramming disc, the ramming hammers correspond to the ramming cylinders, and the drying and cutting disc is used for cutting lime particles which are extruded after ramming and have specific particle sizes. According to the invention, the utilization rateof limestone dust can be increased.

Description

technical field [0001] The invention relates to the technical field of dust treatment devices, in particular to limestone dust collection and treatment equipment. Background technique [0002] The limestone processing environment contains a large amount of limestone dust. Usually, these dusts are discharged directly without utilization. On the one hand, it is easy to cause pollution to the environment, and on the other hand, it is not conducive to the full utilization of resources. Considering that limestone is often used in landscaping in recent years, for example, when fertilizing green plants at the end of spring, nitrogen, scale, and potassium are mainly used. For the acidic soil in the south, it is best to apply finely ground limestone once a year in spring. However, if the dust generated in the limestone production process is directly used for landscape plant maintenance, it will be difficult to exert the best maintenance effect because the particle size of the dust is...

Problems solved by technology

However, if the dust generated in the limestone production process is directly used for landscape plant maintenance, it will be difficult to exert the best maintenance effect due to the different particle sizes of the dust, and some dust will agglomerate in a humid environment.
