Description

Technical Field

[0001] The present invention relates to the technical field of preparing high-purity tridymite sand, and in particular to a device and a method for preparing high-purity tridymite sand. Background Art

[0002] The equipment for preparing high-purity tridymite sand is a device used to crush quartz ore. When preparing high-purity tridymite sand, the selected high-purity quartz ore is cleaned and divided into 2-10 cm blocks, and then the mineralizer is added into the blocks, wherein the mineralizer is one or a mixture of lithium carbonate, sodium carbonate, potassium carbonate, lithium hydride, sodium hydroxide, potassium hydroxide, lithium chloride, sodium chloride, potassium chloride, lithium nitrate, sodium nitrate, and potassium nitrate. The mineralizer and quartz ore are mixed in a certain proportion, and the addition ratio of the mineralizer is 0.001%-5%. The mixture is kept warm in a kiln at 800-1400℃ for 2-10 hours, so that the α-quartz can be fully transformed into tridymite. The tridymite is then placed into the inside of the connecting box through a hopper, and then the extrusion roller is driven by a motor to rotate, so that the tridymite can be broken. The broken quartz needs to be sieved to obtain 20-200 tridymite sand or 200 mesh or finer tridymite powder, and then the obtained tridymite sand / powder is subjected to flotation, acid washing, and magnetic separation to obtain tridymite sand / powder with higher purity.

[0003] The inventors found in their daily work that there are still at least the following problems in the preparation of high-purity tridymite sand: when preparing high-purity tridymite sand, the selected high-purity quartz ore is cleaned and divided into blocks of 2-10 cm, and then a mineralizer is added to the blocks, wherein the mineralizer is one or a mixture of lithium carbonate, sodium carbonate, potassium carbonate, lithium hydride, sodium hydroxide, potassium hydroxide, lithium chloride, sodium chloride, potassium chloride, lithium nitrate, sodium nitrate, and potassium nitrate. The mineralizer and quartz ore are mixed in a certain proportion, and the addition ratio of the mineralizer is 0.001%-5%. The mixture is kept warm in a kiln at 800-1400℃ for 2-10 hours, so that the α-quartz can be fully converted into tridymite. The tridymite is then placed into the inside of the connecting box through a hopper, and then the extrusion roller is driven by a motor to rotate, so that the tridymite can be broken. The broken quartz needs to be sieved to obtain 20-200 tridymite sand or 200 mesh or finer tridymite powder, and then the obtained tridymite sand / powder is floated, pickled, and magnetically separated to obtain tridymite sand / powder with higher purity. However, in actual use, the broken quartz needs to be taken out of the crushing device and sieved, which is more troublesome. Summary of the invention

[0028] Working principle: When preparing high-purity tridymite sand, clean the selected high-purity quartz ore and divide it into 2-10 cm blocks, and then add the mineralizer into the blocks, wherein the mineralizer is one or a mixture of lithium carbonate, sodium carbonate, potassium carbonate, lithium hydride, sodium hydroxide, potassium hydroxide, lithium chloride, sodium chloride, potassium chloride, lithium nitrate, sodium nitrate, and potassium nitrate. The mineralizer and quartz ore are mixed in a certain proportion, and the addition proportion of the mineralizer is 0.001%-5%. The mixture is kept warm in a kiln at 800-1400°C for 2-10 hours, so that the α-quartz can be fully converted into tridymite. The tridymite is then placed into the interior of the connecting box 1 through the hopper 3, and then the extrusion roller 5 is driven by a motor to rotate, so that the tridymite is broken. The broken quartz needs to be sieved to obtain 20-200 tridymite sand or 200 mesh or finer tridymite powder, and then the obtained tridymite sand / powder is subjected to flotation, acid washing, and magnetic separation to obtain tridymite sand / powder with higher purity. When the screening device 8 is in use, the sliding plate 807 is pulled toward the outside of the connection box 1 by the third spring 811, so that the sliding plate 807 slides on the inner wall of the limiting groove 806, and then the bolt 808 is manually controlled to rotate, so that the sliding plate 807 can be squeezed toward the inside of the connection box 1, so that the sliding plate 807 can be well restricted inside the limiting groove 806, and then the small holes opened on the sliding plate 807 and the small holes opened on the surface of the filter plate 801 can be controlled to stagger, so that the specifications of the required quartz stone can be changed to a certain extent, and then the rotating plate 813 is driven to rotate by the second motor 812, so that the rotating plate 813 can be driven to rotate. The moving plate 813 squeezes the squeezing plate 814 at a certain frequency, thereby controlling the squeezing plate 814 to slide on the surface of the sliding rod 803. When the squeezing plate 814 contacts the bottom of the moving groove 802, the squeezing plate 814 is no longer squeezed, and the squeezing plate 814 is squeezed away from the bottom of the inner wall of the moving groove 802 by the second spring 804, thereby returning the squeezing plate 814 to its original position. Repeated operations can make the filter plate 801 vibrate inside the connecting box 1, so that the quartz stone can pass through the filter plate 801 well. When the quartz stone block is crushed by the squeezing roller 5, it directly falls to the top of the filter plate 801 which is inclined. , so that the crushed quartz stone slides on the filter plate 801, and then the quartz stone that meets the specifications falls into the interior of the mobile box 7 through the small holes opened on the filter plate 801, and the quartz stone that does not meet the specifications slides out of the connection box 1 through the gap opened on one side of the connection box 1. The function of the elastic cloth 805 is to prevent the screened quartz stone from falling to the outside of the connection box 1 through the gap. Because a certain solution is arranged inside the mobile box 7, the quartz stone that meets the specifications can be quickly floated, which speeds up the purification efficiency of the quartz stone to a certain extent. When the stirring device 9 is used, that is, when the second motor 812 rotates,The first connecting belt 904 can well drive the rotating rod 903 to rotate inside the moving box 7, and then the rotating rod 903 drives the stirring rod 912 to rotate on the inner wall of the moving box 7. When the stirring rod 912 rotates to the bottom of the moving box 7, the stirring rod 912 drives the second gear 906 to rotate, which can well drive the connecting rod 907 to rotate, and then facilitate the stirring of the quartz stone by the connecting rod 907. When the connecting rod 907 rotates, the second connecting belt 911 can drive the limiting rod 910 to rotate, and then drive the rotating blade 905 to rotate, so that the quartz stone at the bottom of the moving box 7 is stirred inside the moving box 7, so that the quartz stone can be mixed with the solution, which is convenient for the flotation of the quartz stone after screening.
