Drying and screening integrated equipment of rare-earth mineral

Abstract

The invention discloses drying and screening integrated equipment of a rare-earth mineral. The equipment comprises a drying bin, a drying bin base, a screening bin and a screening net, wherein the lower end of the drying bin is clamped inside the drying bin base, a fixing groove is formed in the outer end of the interior of the drying bin base, an inner screening net is clamped inside a clamping groove, and an inner fixing groove is formed in an inner wall of the clamping groove; the left and right outer walls of the screening bin are both provided with outer sliding grooves, the left ends andthe right ends of the interiors of the outer sliding grooves are provided with inner sliding grooves correspondingly, sliding pieces are connected inside the outer sliding grooves and the inner sliding grooves in a sliding mode, and elastic pieces are connected to the lower surface of the screening net in an extruding mode; and the lower end of the screening bin is connected with a discharging bottom plate in a clamped mode, the elastic pieces are fixedly connected to the left end and the right end of the upper surface of the discharging bottom plate, and a discharging port is formed inside the discharging bottom plate. Drying and screening are carried out in the same equipment, a middle step between drying and screening is omitted, so that the working efficiency is improved; and using two sets of equipment for operation is not needed, so that time and labor are saved, the use cost is reduced, and the equipment is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of rare earth production, in particular to an integrated equipment for drying and screening rare earth minerals. Background technique [0002] In nature, rare earth elements mainly exist in the form of single minerals. At present, there are more than 250 kinds of rare earth minerals and minerals containing rare earth elements found in the world, of which 50 to 65 kinds have a rare earth content greater than 5.8%, which can be regarded as independent rare earth elements. Minerals and rare earths need to go through multiple operating steps during production, among which drying and screening are more critical, and independent equipment is usually used for production and processing to achieve the purpose of easy operation, but it still has the following disadvantages in actual use: [0003] 1. Generally, rare earths are dried by natural air drying before processing. The drying efficiency is low, and the rare ear...

AI Technical Summary

Problems solved by technology

[0003] 1. Generally, rare earths are dried by natural air drying before processing. The drying efficiency is low, and the rare earths cannot be dried evenly, which affects the production quality of rare earths. Some equipment uses stirring to dry rare earths. The drying efficiency has been improved, but it still cannot make the rare earth dry better and evenly, and the use effect is poor;

[0004] 2. When screening rare earths, the rare earths are usually placed on the screening net and screened by shaking. This method can only screen a small amount of rare earth minerals, and the screening efficiency is low. Some equipment is used for screening, and large particles that are not screened out Rare earth minerals cannot be processed in time, which affects the efficiency of screening, and will lead to blockage of the screening net, affecting the normal use of the screening net;

[0005] 3. Usually, independent processing equipment is used for rare earth drying and screening, which cannot be used to dry and screen rare earths at one time, which affects the efficiency of rare earth processing. It is necessary to put the dried rare earths into the screening process through technical means. The interior of the equipment is time-consuming and labor-intensive, which increases the cost of use
