Description

High-purity arsenic precipitation separator Technical Field The utility model relates to the technical field of precipitation separation, in particular to a high-purity arsenic precipitation separator. Background Arsenic is a metalloid element, and has three allotropes of gray arsenic (metal arsenic), yellow arsenic and black arsenic, which mainly forms an alloy with copper, lead and other metals, and is also used for manufacturing arsenate, medicines, pesticides and the like, high-purity arsenic can also be used in semiconductor and laser technologies, insoluble compounds are often formed with other metal ions in the preparation process of arsenic, such as arsenate, calcium, ferric iron and the like, insoluble salts can be formed, and the impurities can be removed by a precipitation method, so that purer arsenic compounds are obtained, in addition, the precipitation separation can also help to remove other impurities in solution, and the purity of products is improved. At present, a precipitation separator for preparing high-purity arsenic needs to manually and periodically open a valve to discharge sediment collected at the bottom of a precipitation separation cylinder in the using process, so that the sediment cannot be automatically discharged, excessive sediment accumulation at the bottom of the precipitation separation cylinder is easily caused, and the sediment is discharged along with overflow of clear liquid, so that the precipitation separation effect is reduced. Disclosure of utility model The utility model aims to provide a high-purity arsenic precipitation separator which has the advantages that sediment collected at the bottom of a precipitation separation cylinder can be automatically discharged in the arsenic preparation process, the precipitation separation effect is ensured, and the arsenic preparation purity is improved, and the problems that the sediment collected at the bottom of the precipitation separation cylinder cannot be automatically discharged because a valve is manually and periodically opened in the use process of the conventional high-purity arsenic precipitation separator, and the sediment at the bottom of the precipitation separation cylinder is easily accumulated excessively and overflowed along with clear liquid to be discharged, so that the precipitation separation effect is reduced are solved. In order to achieve the purpose, the high-purity arsenic precipitation separator comprises a precipitation separation cylinder, wherein a vertical pipe is fixedly arranged in the precipitation separation cylinder through a fixing plate, a movable rod is arranged in the vertical pipe, a sliding block is fixedly arranged on the outer surface of the movable rod, one end of the movable rod, which is positioned below the vertical pipe, is fixedly connected with a conical sealing block, a conical pipe is fixedly connected with the lower surface of the precipitation separation cylinder, a floating block is fixedly arranged on the outer surface of the movable rod, a circular liquid collecting tank is fixedly arranged on the edge of the upper surface of the precipitation separation cylinder, a liquid discharge pipe is fixedly connected to the outer surface of the circular liquid collecting tank, a liquid inlet pipe is fixedly arranged on the outer surface of the precipitation separation cylinder, and two ends of the liquid inlet pipe are respectively positioned inside and outside the precipitation separation cylinder.
