Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand processing, in particular to iterative hydrothermal purification equipment. Background Art

[0002] The main purpose of quartz sand purification is to remove small amounts of or trace impurities in it, so as to obtain high-purity quartz sand. These impurities may include iron oxide, aluminum oxide, carbonates and other mineral impurities. The presence of these impurities will affect the purity of quartz sand, and then affect its application performance in various fields. Iterative hydrothermal purification equipment adopts hydrothermal method, which is a purification method under high temperature and high pressure conditions. This method can more effectively remove impurities in quartz sand, such as carbonates, iron oxides, etc., thereby improving the purity of quartz sand.

[0003] The existing patent announcement number CN217600384U discloses a device for purifying quartz sand using an iterative hydrothermal method, including a hydrothermal reactor, a lifting mechanism, a feeding mechanism and an acid cleaning mechanism. The lifting mechanism includes a threaded rod, a threaded sleeve, a first motor and a lifting basket. Threaded rods are symmetrically rotated on both sides of the hydrothermal reactor, and a threaded sleeve is sleeved on the threaded rod. The threaded sleeve and the lifting basket are lifted and lowered by the rotation of the threaded rod to achieve precise control of the pickling time, thereby ensuring the quartz sand pickling purification effect. The quartz sand after pickling is sprayed and cleaned by cleaning the spray rack and the filter screen to fully remove the attached acid.

[0004] When the above-mentioned device transports the quartz sand in the lifting basket to the cleaning chamber for cleaning through a spiral auger, the transportation is not complete and there is still quartz sand remaining in the lifting basket. Due to the long soaking time, the quartz sand is not cleaned thoroughly enough by using a cleaning spray rack, which affects the quality of quartz sand purification. In view of the above problems, an iterative hydrothermal purification equipment is proposed. Utility Model Content
