Classification box of coarse sand table

Номер: CN103934091A
Принадлежит:

The invention discloses a classification box of a coarse sand table. The classification box of the coarse sand table comprises a sluice box, sand blocking bars, an angle iron bracket and a tapered classification chamber, wherein the sand blocking bars are installed between the sluice box and the angle iron bracket, a sand core rod is arranged at the front end of a sand discharging elbow pipe, a conical surface of the head portion of the sand core rod is a sand core cone valve, multiple cone valve upper sand discharging grooves are formed in the sand core cone valve, and the notch of each cone valve upper sand discharging groove is downward formed along the conical surface of the sand core cone valve. According to the classification box of the coarse sand table, due to the fact that the multiple cone valve upper sand discharging grooves are formed in the sand core cone valve and evenly distributed on the sand core cone valve, the traditional linear sand discharging is replaced with the groove ...

Process for recovering cassiterite in fine slit by means of reselection-floating-reselection principle

Номер: CN103934095A
Принадлежит:

The invention discloses a process for recovering cassiterite in fine slit by means of the reselection-floating-reselection principle. The method comprises the procedures of concentration and dehydration, coarse cassiterite separation, preconcentration, flotation desulfurization and the like. Dehydration and concentration and coarse cassiterite separation are performed on tin fine pulp, coarse concentrate is separated out through a table concentrator, a sulphide ore is removed through a reverse flotation method, and tin concentrate is separated out through the table concentrator finally. Compared with the traditional process, even through the procedures of concentration and dehydration, coarse cassiterite separation and impurity removal are required by all the processes, by means of the reselection-floating-reselection principle, the coarse concentrate is obtained through preconcentration firstly, select-in grade of cassiterite in fine slit is improved, quantity of ore entering the main ...

Application of polyether compounds K-41B and K-41Bm derived from K-41A in preparation of anti-HIV drugs

Номер: CN116270590A
Принадлежит:

The invention discloses an application of polyether compounds K-41B and K-41Bm derived from K-41A in preparation of an anti-HIV (Human Immunodeficiency Virus) drug. According to the invention, three cytovirus infection models of TZM-bl-HIV-1IIIB, MT-2-HIV-1IIIB and peripheral blood mononuclear cells (PBMCs)-HIV-1BaL are adopted to verify the anti-HIV activity of the polyether compounds. The anti-HIV-1 activity research of polyether compounds K-41B and K-41Bm derived from marine natural products K-41A is carried out in HIV-1 virus strains with different tropism by adopting three cell infection systems for the first time, and the potential anti-HIV action mechanisms of the polyether compounds K-41B and K-41Bm are disclosed by combining multiple experiments, so that the application has original innovativeness, and is a novel application of the polyether compounds K-41B and K-41Bm in HIV-1 virus strains with different tropism. Moreover, the invention finds that K-41B and K-41Bm are possibly ...

siRNA capable of suppressing expression of gene TLR2 of human immune cell and application of siRNA

Номер: CN103589727A
Принадлежит:

The invention discloses a siRNA capable of suppressing the expression of a gene TLR2 of a human immune cell. A positive-sense strand sequence of the siRNA is 5'-CUUGACCUGUCCAACAACAUU-3', and an antisense strand sequence of the siRNA is 3'-UUGAACUGGACAGGUUGUUGU-5'. The siRNA disclosed by the invention can obviously suppress the expression of the gene TLR2 of the human immune cell; a TLR2 receptor mediates various bacterium or virus infections, so that the siRNA synthesized by a method disclosed by the invention can be applied to a biological medicine preparation which is implanted into a patient infected by bacteria or viruses to treat bacterial or viral infection diseases, so that the immunity of a human body can be improved.
