Description

Technical Field

[0001] The invention relates to the technical field of quartz powder, and in particular to a spherical quartz powder purification process and purification equipment. Background Art

[0002] Quartz powder is made of natural quartz as raw material, and is processed through processes such as sorting, crushing, washing, purification, drying, iron removal, grinding, and grading. The main equipment for producing quartz powder includes stone knockers, crushers, vibrating screens, etc. After production, quartz powder needs to be purified to improve its performance. Screening mechanism is required during the purification process of quartz powder. Screening is an important step in the purification process of quartz powder. It is mainly used to remove large impurities and fine powder, laying a good foundation for subsequent steps.

[0003] For example, the Chinese patent with application number: 202310272662.3, entitled A quartz sand purification process, discloses a quartz sand purification process, comprising the following steps: Step 1, crushing the quartz sand ore to a particle size of less than 0.3 mm to obtain ore particles; Step 2, washing the ore particles, removing the mud and water in the ore particles, and obtaining intermediate A; Step 3, adding a foaming agent to water, adding it to intermediate A after it is completely dissolved, and stirring it fully; Step 4, adding dilute sulfuric acid while stirring, removing the surface foam, filtering, and drying to obtain intermediate B; Step 5, adding mixed acid to intermediate B for soaking, washing to neutrality, and drying to obtain intermediate C; Step 6, adding intermediate C to a magnetic separation device for magnetic separation to obtain a quartz sand finished product. The present invention can quickly perform magnetic separation by using a magnetic separation device.

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0045] See also Figure 1-9 The present embodiment provides a spherical quartz powder purification process, comprising the following steps:

[0046] S1: The quartz ore is crushed to less than 25 mm by a cone crusher, then ground by a ball mill and screened out to a suitable particle size by a screening drum 1;

[0047] S2: Scrub the quartz particles with a slurry concentration of 50%-60% and separate the mud simultaneously. Extend the scrubbing time to 30-40 minutes under the condition of slurry concentration of 50%-60%. The scrubbing machine can simultaneously complete the desludging and particle size coarse and fine separation, eliminating the need for separate classification equipment.

[0048] S3: A two-stage high gradient magnetic separator 92 is used to remove ferromagnetic minerals and magnetic impurities in quartz, a 6000 Gauss drum magnetic separator 92 is used to remove strongly magnetic iron, and a 15000 Gauss high gradient magnetic separator 92 is used to remove weakly magnetic iron, replacing the gravity separation or flotation process;

[0049] S4: Soak in a mixed solution of hydrochloric acid and sulfuric acid at 60-75°C for 4-8 hours to remove residual metal oxides and then dehydrate and dry. Use hydrochloric acid + sulfuric acid (concentration 10-15%) to soak at 60-75°C for 4-8 hours to simultaneously dissolve metal oxides and some non-metallic impurities, eliminating the complex high-temperature equipment of chlorination roasting. After acid leaching, dehydrate directly through a centrifuge and complete drying in combination with a hot air dryer without the need for a separate concentration process.

[0050] A quartz powder purification and impurity removal device, which is used to implement the above-mentioned spherical quartz powder purification method, the screening drum 1 is divided into a storage space 12 and a processing space by a top plate 11, and the processing space is divided into a filter space 13 and a waste space 14 by a partition assembly. The screening drum 1 is an important structure required for quartz powder purification and impurity removal, and is mainly used to remove large impurities and fine powders, laying a good foundation for subsequent steps. By setting the filter space 13 and the waste space 14, different materials after filtration can be stored separately. The partition assembly includes a fixed connection in the screening drum 1 The fixed partition frame 81 has two baffles 82 slidably connected in the fixed partition frame 81. The two baffles 82 in the fixed partition frame 81 are driven by the same driving source to intermittently move up and down. The storage space 12 is connected with the filter material space 13 through the open pipe 91. The open pipe 91 is provided with a timer switch. The storage space 12 is connected with the conveyor. The quartz powder raw material to be processed is conveyed to the storage space 12 in the screening drum 1 through the conveyor for storage. The storage space 12 is located in the upper part of the screening drum 1, the processing space is located in the lower part of the screening drum 1, and the filter material space 13 is connected with the filter material space 13. The quartz powder screened in the middle is transported to the next equipment for processing through the feeding pipe. The top plate 11 is rotatably connected with a support rod 15, and the screening drum 1 is rotatably connected with a rotating ring 16. Multiple groups of screening mechanisms are arranged between the support rod 15 and the rotating ring 16; it also includes a dredging component, which is arranged on the top plate 11; when the support rod 15 rotates, the screening mechanism located in the filter material space 13 rotates and shakes to achieve screening. Through the rotation and shaking of the screening mechanism, the quartz powder inside the screening mechanism can be driven to fully move, avoiding the situation of accumulation caused by movement in one direction. The screening efficiency of the screening mechanism is improved. The screening mechanism flips when switching between the filter material space 13 and the waste material space 14, and the flipped screening mechanism is dredged by the dredging component. The material screened by the screening mechanism can be dumped by flipping the screening mechanism, so as to avoid the filtered material remaining in the screening mechanism for a long time and affecting its subsequent screening effect. The flipping of the screening mechanism is carried out synchronously with the rotation of the support rod 15, and multiple screening mechanisms will only flip after they are rotated and shaken in turn, thereby optimizing the continuity of quartz powder screening and impurity removal.

[0051] In an embodiment further provided by the present invention, the screening mechanism includes a fixed cylinder 21 fixedly connected to the support rod 15, a connecting rod 1 22 is slidably connected in the fixed cylinder 21, a rotating cylinder 23 is rotatably connected to the rotating ring 16, a connecting rod 24 is slidably connected in the rotating cylinder 23, a screening frame 25 is arranged between the connecting rod 1 22 and the connecting rod 2 24, a limiting rod 26 is fixedly connected to the connecting rod 1 22, the connecting rod 1 22 slides laterally in the fixed cylinder 21, and one end of the connecting rod 1 22 connected to the screening frame 25 is rotatably connected, the connecting rod 2 24 is also slidably connected in the rotating cylinder 23, but the connecting rod 2 24 and the screening frame 25 are fixedly connected.

[0052] Furthermore, a track groove 3 is provided on the top plate 11. The track groove 3 is connected end to end by an arc groove part and a wave groove part. The limit rod 26 is slidably connected in the track groove 3. The arc groove part of the track groove 3 is arranged in the movement stroke of the screening mechanism to enter the waste space 14 and move from the waste space 14 to the material receiving point of the storage space 12, and the wave groove part is arranged in the movement stroke of the screening mechanism after the material receiving is completed until it is about to enter the waste space 14. When the screening mechanism is located at the wave groove part of the track groove 3, the screening mechanism not only rotates with the support rod 15 but also slides horizontally, so that the quartz powder in the screening mechanism can be fully moved, which is convenient for screening and impurity removal.

[0053] Furthermore, a rotating assembly for driving the rotating drum 23 to flip is provided on the screening drum 1, and the rotating assembly includes two arcuate tooth plates 4 fixedly connected to the screening drum 1, the arcuate tooth plates 4 are arranged in the grooves of the inner wall of the screening drum 1, and the two arcuate tooth plates 4 are arranged in the waste space 14. When the screening mechanism enters the waste space 14, it flips under the action of the arcuate tooth plates 4, thereby realizing the dumping of the screened waste.

[0054] In an embodiment further provided by the present invention, a limiting unit is provided on the rotating ring 16, and the limiting unit includes a worm 51 rotatably connected to the rotating ring 16, a worm wheel 52 is fixedly connected to the rotating drum 23, the worm 51 is meshed with the worm wheel 52, and a gear 53 is also fixedly connected to the worm 51, and the gear 53 is meshed with two arc-shaped tooth plates 4 in sequence during the movement of the gear 53. Through the self-locking function of the worm 51 and the worm wheel 52 in the limiting unit, the possibility of the screening frame 25 shaking and flipping due to the shaking of the quartz powder during the rotation of the support rod 15 can be avoided.

[0055] In the embodiment provided by the present invention, the dredging assembly includes a dredging rod 61 slidably connected to the top plate 11, and the bottom end of the dredging rod 61 is fixedly connected to a dredging disk 62; a rotating column 63 is rotatably connected to the top plate 11, and a corrugated annular groove 64 is provided on the rotating column 63; the top end of the dredging rod 61 is fixedly connected to a sliding rod 65, and the sliding rod 65 is slidably connected in the corrugated annular groove 64; the dredging disk 62 is arranged above the waste space 14, and is used to knock and dredge the screening mechanism after it is flipped, so as to facilitate the falling of materials stuck in the screening frame 25.

[0056] Specifically, a driving assembly is provided on the top plate 11, and the driving assembly includes a driving rod 71 rotatably connected to the top plate 11, and a residual tooth disk 1 72 and a residual tooth disk 2 73 are fixedly connected to the driving rod 71; a gear 2 74 is provided on the support rod 15, and the gear 2 74 is meshed with the residual tooth disk 1 72; a gear 3 75 is fixedly connected to the rotating column 63, and the gear 3 75 is meshed with the residual tooth disk 2 73. The advantage of the setting of the driving assembly is that the rotation of the support rod 15 and the up and down movement of the dredging assembly can be realized by the rotation of a driving source, and the screening mechanism that has been flipped and stopped rotating can be reasonably controlled to be knocked and dredged during the interval of the screening mechanism receiving the material.

[0057] Working principle: during operation, the driving rod 71 rotates to drive the residual tooth disc 1 72 and the residual tooth disc 2 73 arranged thereon to rotate synchronously. When the residual tooth disc 1 72 meshes with the gear 2 74 on the support rod 15, the residual tooth disc 2 73 does not mesh with the gear 3 75 on the rotating column 63 at this time. The residual tooth disc 1 72 cooperates with the gear 2 74 to drive the support rod 15 to drive the multiple screening mechanisms to rotate. When one of the screening mechanisms moves to the bottom of the open tube 91, the residual gear disc 1 separates from the gear 2 74, the support rod 15 stops rotating, and the timing switch on the open tube 91 is turned on, so that the quartz powder to be processed in the storage space 12 falls into the screening frame 25 in the screening mechanism through the open tube 91. The timing switch in the open tube 91 is turned on after the support rod 15 stops rotating, and is closed before the support rod 15 is about to rotate again. When the support rod 15 rotates again, the open tube 91 does not leak material.

[0058] And in the rotation stroke of the support rod 15, the rest of the screening mechanism loaded with the quartz powder to be processed and in the filter material space 13 rotates synchronously. When it rotates, the limit rod 26 on the connecting rod 1 22 enters the wave groove part of the track groove 3, so that the connecting rod 1 22 pulls the screening frame 25 to shake, so that the quartz powder in the screening frame 25 is fully shaken to achieve screening. As the support rod 15 rotates, the screening mechanism that is about to enter the waste space 14 from the filter material space 13 will flip over, and when the support rod 15 rotates, the driving source that drives the baffle 82 to move downward works synchronously to retract the baffle 82 into the fixed partition frame 81. At this time, the screening mechanism is completed. When entering the waste space 14, the gear 1 53 connected to the worm 51 at the other end of the screening frame 25 meshes with the arc-shaped toothed plate 4, thereby driving the worm 51 to rotate and mesh with the worm wheel 52 to drive the drum 23 to rotate. The rotation of the drum 23 drives the screening frame 25 fixedly connected thereto to flip through the connecting rod 24, so that the screened materials remaining in the screening frame 25 can be poured into the waste space 14 for unified storage. The driving source for driving the baffle 82 to move downward is started with the operation of the support rod 15, and the stroke for the driving source to drive the baffle 82 to reset is started after a screening mechanism enters the waste space 14 from the filter space 13, and before the screening mechanism flips over.

[0059] And when the flipped screening frame 25 enters the waste space 14, the residual tooth disk 1 72 does not mesh with the gear 2 74 on the support rod 15, and the support rod 15 stops rotating. At this time, the driving rod 71 drives the residual tooth disk 2 73 to mesh with the gear 3 75 on the rotating column 63, driving the rotating column 63 to rotate. The rotating column 63 rotates through the corrugated annular groove 64 arranged thereon and cooperates with the sliding rod 65 arranged on the dredging rod 61, driving the dredging rod 61 to drive the dredging disk 62 to move up and down to collide with the flipped screening frame 25, so that the material stuck on the screen of the screening frame 25 falls off, further improving the screening effect of the screening mechanism.

[0060] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
