The utility model discloses a dust removal device of a mining unloading station, which relates to the technical field of mining equipment and comprises an unloading station body and a dust removal box, one side of the unloading station body is provided with the dust removal box, the top end of the dust removal box is fixedly provided with a fan box, one side of the dust removal box is connected with a dust-gas pipeline in a circulating manner, and the dust-gas pipeline is provided with a fan. And an air volume adjusting valve is fixedly mounted in the middle of the dust-gas pipeline. The fan box of the dust removal device of the mining unloading station extracts dust-containing gas generated by the unloading station body through the dust-gas pipeline and the dust hood, the air volume adjusting valve on the dust-gas pipeline can adjust the air volume, the dust-containing gas enters the dust removal box to be treated, dust is discharged from the bottom dust discharge port, and purified gas is discharged from the purified gas outlet. The water pump above the water tank conveys water to the water supply pipe annularly distributed on the outer side of the dust suction hood through the connecting water pipe and the water supply pipe, then the water is sprayed out through the multiple mist spray heads on the inner side to spray and reduce dust in the dust suction hood, the fixing frame is used for stabilizing the water supply pipe, efficient dust removal is achieved, and the unloading station environment is improved.

The invention discloses a gene PvHsf16 for coding a plant heat shock transcription factor and application of the gene PvHsf16. The gene is derived from an up-regulated differential expression gene in a member of a switchgrass Hsf gene family subjected to cadmium (Cd) stress treatment. By constructing a PvHsf16 yeast expression vector, PvHsf16 cells show more obvious cadmium resistance, and the gene can improve the cadmium resistance of yeast. PvHsf16 is positioned in a cell nucleus, the PvHsf16 gene is overexpressed in arabidopsis thaliana, and compared with a wild type treated by CdCl2, an arabidopsis thaliana PvHsf6 overexpressed strain has enhanced cadmium tolerance, and the chlorophyll content, the root length and the biomass of the strain are remarkably improved. The PvHsf16 gene provides a gene resource for cultivating the germplasm of the energy grass-cadmium remediation dual-purpose switchgrass, can be applied to the treatment of cadmium polluted areas, and plays an important role in the aspects of researching a plant bioremediation technology, improving the heavy metal pollution condition of soil and the like.

This invention discloses a gene, PvHsf16, encoding a plant heat shock transcription factor, and its applications. This gene originates from differentially expressed genes upregulated in members of the Hsf gene family of switchgrass under cadmium (Cd) stress. By constructing a yeast expression vector for PvHsf16, PvHsf16 cells exhibited significantly greater cadmium tolerance, indicating that this gene enhances yeast cadmium resistance. PvHsf16 is located in the cell nucleus. Overexpression of the PvHsf16 gene in Arabidopsis thaliana, compared to the wild type under CdCl2 treatment, showed enhanced cadmium tolerance in the PvHsf6 overexpressing lines, with significantly increased chlorophyll content, root length, and biomass. The PvHsf16 gene provides a genetic resource for cultivating switchgrass germplasm suitable for both energy grass and cadmium remediation, and can be applied to the remediation of cadmium-polluted areas, playing an important role in researching phytoremediation technologies and improving soil heavy metal pollution.
