Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of zirconium oxide extraction, in particular to a multi-stage purification device for extracting zirconium oxide from zircon sand. BACKGROUND

[0002] Zirconium oxide is the main oxide of zirconium, which is usually white, odorless and tasteless crystal, and is difficult to dissolve in water, hydrochloric acid and dilute sulfuric acid. It usually contains a small amount of hafnium dioxide. It is not chemically active and has the properties of high melting point, high resistivity, high refractive index and low thermal expansion coefficient, making it an important high-temperature resistant material, ceramic insulating material and ceramic light shielding agent, and also the main raw material of artificial drill. In the purification of zirconium oxide, since there is a lot of broken iron in zirconium oxide, the broken iron in zirconium oxide needs to be cleaned during the purification of zirconium oxide, otherwise it will affect the purity of zirconium oxide, and the filter plate may be clogged during the extraction of zirconium oxide crystals.

[0003] Chinese patent CN211283749U discloses an extraction device for zirconium oxide purification, which comprises a processing box, a plurality of supporting legs are fixedly connected to the bottom of the processing box, a box cover is connected to the top of the processing box, a motor is fixedly connected to the top of the box cover, an output shaft is fixedly connected to the output end of the motor, an iron removal frame is fixedly connected to the inner side wall of the processing box, the output shaft penetrates through the box cover and the iron removal frame, a plurality of magnetic rods are fixedly connected to the outer side wall of the output shaft in the iron removal frame, the processing box is connected with the iron removal frame through a connecting mechanism, the output shaft is connected with a filtering mechanism through an engaging mechanism, an installation port is formed in the side wall of the processing box, and a connecting pipe is fixedly connected to the inner side wall of the installation port.

[0004] The above scheme can remove the iron in zirconium oxide to some extent, but the content of iron in zircon sand is relatively low, and when extracting zirconium oxide from zircon sand, it needs to go through multiple chemical reaction steps and wait for the generation of precipitate. Basically, the precipitate is taken out and reacted with new chemical reagents each time, which consumes a lot of time and limits the production. SUMMARY

[0005] In order to solve the above problems, a multistage purification device for extracting zirconium oxide from zircon sand is provided. Zircon sand is put into the shell from the feed port, and then the driving device is started. The driving device drives the threaded rod to rotate and descend. The injection device will inject chemical reagents into the shell in advance. The injection device needs to inject different chemical reagents in batches. Each batch of chemical reagents needs to react with zircon sand separately. The zircon sand put in is immersed in the chemical reagent with the filter plate. After one reaction, the driving device drives the filter plate and the rotating plate to rise. During the rising process, most of the reacted solution remains at the bottom of the shell. However, a small part of the solution cannot be separated out because the filter hole is blocked by the solid matter remaining on the filter plate. The rotating plate rotates during the lifting and lowering process of the filter plate. The rotating plate pushes the solid matter after the reaction to rotate. The solid matter slides and accumulates on one side of the rotating plate under the push of the rotating plate. The gas supply device intermittently supplies gas to the shell under the control of the trigger device. The gas supply device will only start when the filter plate rises above the gas supply device. The intermittent gas supply of the gas supply device blows away the solid matter blocking the filter hole, so that the solution remaining above the filter plate falls through the filter hole. To complete the purification of zirconium oxide, the above steps need to be repeated several times. In this way, the time for waiting for the zircon sand to precipitate after the reaction is avoided, and the overall reaction rate is improved.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means and specific purposes and functions of the present application, the present application is described in further detail below in combination with the drawings and specific embodiments.

[0032] Reference is made to Figure 1 , Figure 3 andFigure 8 : A multistage purification device for extracting zirconium oxide from zircon sand, comprising a shell 1 and a processing device 2; the processing device 2 comprises a driving device 21, a filter plate 22, a rotating plate 23, a gas supply device 24, an injection device 25, a threaded rod 26 and a trigger device 27; the shell 1 is in a cylindrical structure, the side wall of the shell 1 is respectively provided with a feeding port and a discharging port, and the driving device 21 is arranged at the top of the shell 1; the filter plate 22 is in a circular structure, and is arranged in the shell 1 along the axis of the shell 1, and is used for receiving zircon sand; the rotating plate 23 is provided in plurality, and is arranged vertically on the upper part of the filter plate 22 around the axis of the shell 1, the upper end surface of the filter plate 22 is in contact with the bottom of the rotating plate 23, and the driving device 21 is used for driving the rotating plate 23 to rotate around the axis of the shell 1; the gas supply device 24 is arranged on the side wall of the shell 1, and is started when the filter plate 22 moves to the upper part of the gas supply device 24, and the gas supply device 24 can blow gas into the shell 1; the trigger device 27 is arranged on the driving device 21, and is triggered synchronously with the operation of the driving device 21, and is used for controlling the gas supply device 24 to supply gas intermittently; the injection device 25 is arranged on the side wall of the shell 1 below the gas supply device 24, and can inject chemical reagents into the shell 1; the threaded rod 26 is arranged in the shell 1 along the axis of the shell 1, and the rotating plate 23 is located below the threaded rod 26, the driving device 21 is in threaded cooperation with the threaded rod 26, a groove is arranged on the side wall of the threaded rod 26 along the axis of the threaded rod 26, a through hole is arranged in the upper part of the shell 1 for the threaded rod 26 to pass through, a protrusion is fixedly arranged on the side wall of the through hole, the protrusion is in sliding cooperation with the groove, and the driving device 21 drives the filter plate 22 and the rotating plate 23 to ascend and descend synchronously through the threaded rod 26 when the driving device 21 operates.

[0033] The side wall of the shell 1 is provided with an inlet and an outlet. When the zircon sand is not put into the shell 1, the filter plate 22 is located at the highest position. At this time, the filter plate 22 is still below the inlet, but the distance between the inlet and the filter plate is the shortest. The zircon sand does not fall for a long time, and the impact force of the zircon sand on the filter plate 22 is also reduced, thereby preventing the situation that the zircon sand with light texture is lifted by the swirling airflow. In this way, the situation that the zircon sand with light texture floats out of the inlet during feeding can be avoided. During purification, the zircon sand is put into the shell 1 from the inlet. Then, the driving device 21 is started. The driving device 21 drives the threaded rod 26 to rotate and descend. The injection device 25 will inject chemical reagents into the shell 1 in advance. The injection device 25 needs to inject different chemical reagents in batches. Each batch of chemical reagents needs to react with the zircon sand separately. The zircon sand put in is immersed in the chemical reagents with the filter plate 22. After one reaction, the driving device 21 drives the filter plate 22 and the rotating plate 23 to rise. During the rising process, most of the reacted solution remains at the bottom of the shell 1, but a small part of the solution cannot be separated out because the filter holes are blocked by the solid substances on the filter plate 22. During the rising and falling process of the filter plate 22, the rotating plate 23 rotates. The rotating plate 23 pushes the reacted solid substances to rotate. The solid substances slide and accumulate on one side of the rotating plate 23 under the pushing of the rotating plate 23. The gas supply device 24 is controlled by the trigger device 27 to supply gas to the shell 1 intermittently. The gas supply device 24 is started only when the filter plate 22 rises above the gas supply device 24. The intermittent gas supply of the gas supply device 24 blows away the solid substances blocking the filter holes, so that the solution remaining above the filter plate 22 falls through the filter holes. Then, the solution in the shell 1 is discharged. Another chemical reagent is injected into the shell 1 through the injection device 25. The driving device 21 drives the filter plate 22 to descend for secondary reaction. To complete the purification of zirconium oxide, the above steps need to be repeated multiple times. In this way, the time for waiting for the zircon sand to precipitate after reaction is avoided, and the overall reaction rate is improved.

[0034] With reference to Figure 3 and Figure 5 The driving device 21 comprises a rotary driver 211, a first gear 212, a first tooth ring 213 and a transmission device 214. The rotary driver 211 is fixedly arranged above the shell 1, and the output end of the rotary driver 211 is vertically downward. The first gear 212 is fixedly arranged on the output end of the rotary driver 211. The first tooth ring 213 is arranged on the threaded rod 26 along the axis of the threaded rod 26. The first gear 212 and the first tooth ring 213 are meshed with each other. The inner wall of the first tooth ring 213 is provided with a threaded groove. The first tooth ring 213 is threadedly connected with the threaded rod 26 through the threaded groove on the inner wall. The first tooth ring 213 drives the rotating plate 23 to rotate through the transmission device 214.

[0035] When the rotating driver 211 is started, the rotating driver 211 drives the first gear ring 213 to rotate through the first gear 212. Since the first gear ring 213 is threadedly connected with the threaded rod 26, and since the threaded rod 26 has a groove on the side wall and is slidably connected with the protrusion on the side wall of the through hole at the top of the shell 1, the threaded rod 26 does not rotate by itself. Thus, when the first gear ring 213 rotates, the threaded rod 26 will ascend or descend along the axis of the shell 1. When the first gear ring 213 rotates, the first gear ring 213 drives the rotating plate 23 to rotate through the transmission device 214.

[0036] With reference to Figures 8-10 The transmission device 214 includes a second gear ring 2141, a transmission shaft 2142, a second gear 2143, and a third gear ring 2144. The second gear ring 2141 is arranged on one side of the first gear ring 213, and the first gear ring 213 and the second gear ring 2141 are in meshing connection with each other. The transmission shaft 2142 is arranged on the second gear ring 2141 along the axis of the second gear ring 2141. The second gear 2143 is fixedly arranged on the bottom of the transmission shaft 2142 along the axis of the transmission shaft 2142. The third gear ring 2144 is rotatably arranged on the threaded rod 26 along the axis of the threaded rod 26, and the bottom of the third gear ring 2144 is fixedly connected with the upper portion of the rotating plate 23. The third gear ring 2144 is in meshing connection with the second gear 2143.

[0037] When the rotating driver 211 drives the first gear ring 213 to rotate through the first gear 212, the first gear ring 213 drives the threaded rod 26 in threadedly connected therewith to ascend or descend. The first gear ring 213 drives the second gear 2143 to rotate through the second gear ring 2141 and the transmission shaft 2142 fixedly arranged on the second gear 2143. Since the second gear 2143 and the third gear ring 2144 are in meshing connection with each other, the second gear 2143 is driven to rotate by the third gear ring 2144, so as to drive the rotating plate 23 in fixed connection with the third gear ring 2144 to rotate.

[0038] With reference to Figure 9 The transmission device 214 further includes a synchronization frame 2145. The synchronization frame 2145 is sleeved on the second gear 2143 and the third gear ring 2144 at two ends thereof. The transmission shaft 2142 is in slidable connection with the second gear ring 2141. The cross section of the transmission shaft 2142 is in non-circular structure.

[0039] When the rotating driver 211 drives the first tooth ring 213 to rotate through the first gear 212, the first tooth ring 213 drives the threaded rod 26 to lift, and the first tooth ring 213 drives the second gear 2143 to rotate through the transmission shaft 2142 fixedly arranged on the second gear 2143 and the second tooth ring 2141. Since the second gear 2143 and the third tooth ring 2144 are engaged with each other, the second gear 2143 is driven to rotate by the third tooth ring 2144, so that the rotating plate 23 fixedly connected with the third tooth ring 2144 rotates. After the rotating driver 211 is started, the first tooth ring 213 drives the threaded rod 26 to lift, and if the synchronous frame 2145 is not arranged, the second gear 2143 and the third tooth ring 2144 will be disengaged, so that the rotating plate 23 no longer rotates, and the solid objects on the filter plate 22 will gradually tend to be flat, so as to completely block the filter holes on the filter plate 22. In order to avoid the above situation, the synchronous frame 2145 is arranged between the second gear 2143 and the third tooth ring 2144. Since the third tooth ring 2144 is fixedly connected with the rotating plate 23, and one end of the synchronous frame 2145 is clamped between the third tooth ring 2144 and the rotating plate 23, when the rotating plate 23 lifts, the synchronous frame 2145 also lifts synchronously with the rotating plate 23, and the second gear 2143 at the other end of the synchronous frame 2145 also lifts synchronously. The transmission shaft 2142 fixedly arranged on the upper portion of the second gear 2143 has a non-circular cross-section, and the transmission shaft 2142 has a columnar structure. The second tooth ring 2141 is slidably arranged along the axial direction of the shell 1. When the transmission shaft 2142 lifts with the second gear 2143, the second gear 2143 drives the transmission shaft 2142 to move along the axial direction of the shell, and the second tooth ring 2141 does not move in the direction of the shell, so that the transmission shaft 2142 relatively slides with the second tooth ring 2141, and the transmission effect of the second tooth ring 2141 on the transmission shaft 2142 is not affected.

[0040] With reference to Figure 1 and Figure 6 The trigger device 27 comprises a fixed plate 271, a plurality of poking blocks 272, a support 273 and a plurality of trigger pieces 274. The fixed plate 271 has an annular structure, and the fixed plate 271 is fixedly arranged on the upper portion of the first tooth ring 213 along the first tooth ring 213. The plurality of poking blocks 272 are uniformly fixedly arranged on the upper portion of the fixed plate 271 around the axis of the fixed plate 271. The support 273 is fixedly arranged above the fixed plate 271. The plurality of trigger pieces 274 are uniformly fixedly arranged on the lower portion of the support 273 around the axis of the fixed plate 271. The poking blocks 272 can trigger the trigger pieces 274 when the poking blocks 272 rotate around the axis of the fixed plate 271. One side of the trigger pieces 274 is provided with a controller, and the trigger pieces 274 control the air supply device 24 through the controller.

[0041] When the first tooth ring 213 rotates, the first tooth ring 213 drives the fixed plate 271 to rotate synchronously, the push block 272 fixedly arranged on the fixed plate 271 can push the trigger 274 on the support 273, and then the push block 272 triggers the trigger 274. The trigger 274 can be triggered only when the push block 272 passes by. After the trigger 274 is triggered each time, a signal is sent to the controller on one side. After the controller receives the signal, the controller controls the air supply device 24 to supply air. When the trigger 274 is not triggered by the push block 272, the air supply device 24 stops supplying air.

[0042] With reference to Figure 3 and Figure 4 The processing device 2 further comprises a drainage valve 28; the drainage valve 28 is fixedly arranged at the bottom of the shell 1.

[0043] The drainage valve 28 is arranged at the bottom of the shell 1. After the filter plate 22 rises, the filter plate 22 separates the solid from the solution. Then the drainage valve 28 is opened, and the solution at the bottom of the shell 1 is drained. After the solution is completely drained, the drainage valve 28 is closed, and the injection device 25 injects new chemical reagents into the shell 1.

[0044] With reference to Figure 2 and Figure 3 The injection device 25 comprises a plurality of spray heads 251; the spray heads 251 are arranged on the side wall of the shell 1, and an angle is formed between the axis of the spray head 251 and the radial direction of the shell 1.

[0045] When it is necessary to inject new chemical reagents into the shell 1, the spray head 251 is opened. The spray head 251 arranged obliquely can make the chemical reagents slide along the inner wall of the shell 1 to the bottom of the shell 1, preventing the splashing of the chemical reagents.

[0046] With reference to Figure 2 and Figure 3 The injection device 25 further comprises a reversing valve 252; the reversing valve 252 is arranged at the end of the spray head 251, and the reversing valve 252 can switch different chemical reagents and clean water.

[0047] Since the chemical reagents added by the spray head 251 are different each time, in order to avoid the mutual mixing of different reagents, before adding new chemical reagents each time, the reversing valve 252 is switched to clean water, and the clean water is sprayed into the shell 1 through the spray head 251. The clean water can clean the inner wall of the shell 1, ensuring that the subsequent added chemical reagents will not be contaminated.

[0048] With reference to Figure 7 and Figure 8The processing device 2 further comprises a limiting block 221 and a limiting groove 222; the limiting block 221 is fixedly arranged on the side wall of the filter plate 22; the limiting groove 222 is arranged on the inner wall of the shell 1 along the axis of the shell 1, and the limiting block 221 and the limiting groove 222 are in sliding fit.

[0049] Although the rotating plate 23 is in rotating fit with the filter plate 22, under the action of friction, the filter plate 22 may rotate together with the rotating plate 23, in order to avoid the above-mentioned situation, the limiting block 221 is fixedly arranged on the side wall of the filter plate 22, and the limiting block 221 and the limiting groove 222 are in sliding fit, so that the filter plate 22 can only slide along the axis direction of the shell 1 and cannot rotate by itself.

[0050] Referring to Figure 2 and Figure 3 The air supply device 24 comprises a pump body 241 and a switch valve 242; the switch valve 242 is arranged in plurality, and the switch valve 242 is fixedly arranged on the side wall of the shell 1 around the axis of the shell 1; the pump body 241 is arranged at the end of the switch valve 242.

[0051] The pump body 241 can blow the air outside into the shell 1, since the pump body 241 only starts to operate when the filter plate 22 is located at the upper part of the switch valve 242, so when the filter plate 22 is located at the upper part of the switch valve 242, the pump body 241 blows the air outside into the shell 1, the air passes through the filter holes on the filter plate 22, the intermittent air supply of the air supply device blows away the solid objects blocking the filter holes, so that the solution on the upper part of the filter plate 22 falls from the filter holes, and the separation speed of the solution above the filter plate and the solid after reaction is accelerated, since the purification of zirconium oxide needs to repeat the above steps for multiple times, so the time for waiting for the zircon sand to precipitate after reaction is avoided, and the overall reaction rate is improved.

[0052] The above embodiments only express one or several embodiments of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
