Description

Technical Field

[0001] The present invention relates to the technical field of ammonium paratungstate production, and in particular to an ion exchange device for ammonium paratungstate production. Background Art

[0002] Ammonium paratungstate is a chemical substance, mainly white crystals, in two forms: flaky and needle-shaped. It is mainly used to manufacture tungsten trioxide or blue tungsten oxide to produce tungsten powder, and can also be used to manufacture ammonium metatungstate and other tungsten compounds or as an additive in the petrochemical industry. It is an important inorganic salt product, and its main production processes include crushing, alkali boiling, pressure filtration, ion exchange, crystallization, drying, etc.

[0003] In the current ion exchange process for ammonium paratungstate production, sodium tungstate solution is passed through strongly basic anion exchange resin, and then resolved with a mixed solution of ammonium chloride - ammonium hydroxide. Chloride ions are adsorbed on the exchange resin, and the generated ammonium tungstate enters the solution and then crystallizes and dries to obtain ammonium paratungstate crystals. However, during the resolution process, some of the generated ammonium tungstate solution will adhere to the exchange resin and cannot enter the next step, and will be discharged with the sodium tungstate solution when the sodium tungstate solution passes through the exchange resin next time, resulting in waste of ammonium paratungstate.

Detailed implementation mode

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Embodiment:

[0034] Referring to Figures 1 to 4 , an ion exchange device for the production of ammonium paratungstate disclosed by the present invention includes a housing 1, a first water pump 2 and a second water pump 3 fixedly connected to the top of the housing 1. The input ends of the first water pump 2 and the second water pump 3 are respectively communicated with a sodium tungstate solution and an analytical agent, and the analytical agent is a mixed solution of ammonium chloride and ammonium hydroxide.

[0035] The inner top wall of the housing 1 is rotatably connected with a rotating cylinder 4 with an open top. The output ends of the first water pump 2 and the second water pump 3 both extend into the rotating cylinder 4. The outer peripheral surface of the rotating cylinder 4 is provided with a hollow-out structure, and an exchange resin 5 is fixedly sleeved on the outer peripheral surface of the rotating cylinder 4. The exchange resin 5 is a strongly basic anion exchange resin 5.

[0036] A partition 6 is fixedly connected to the lower half of the housing 1. A discharge pipe 7 is fixedly penetrated through the top of the partition 6, and the bottom end of the discharge pipe 7 extends to the outside of the housing 1. The discharge pipe 7 is controlled to be opened and closed by a valve. In the initial state, the discharge pipe 7 is in an open state.

[0037] The first water pump 2 works to pump the sodium tungstate solution into the rotating cylinder 4. The sodium tungstate solution contacts the exchange resin 5 and passes through the exchange resin 5 to fall onto the top of the partition 6, and is discharged from the housing 1 through the discharge pipe 7 and sent to a sewage treatment station for purification treatment.

[0038] A rotating rod 8 is vertically rotatably connected in the housing 1, and the rotating rod 8 rotatably penetrates through the partition 6. A driving gear 9 is fixedly sleeved on the outer peripheral surface of the rotating rod 8, and a driven gear 10 is fixedly sleeved on the upper half of the outer peripheral surface of the rotating cylinder 4. The driving gear 9 meshes with the driven gear 10. A driving part 11 is arranged on one side of the housing 1.

[0039] The driving part 11 includes an air pump 112 fixedly connected to the side wall of the housing 1 and a guiding pipe 111 fixedly connected to the inner wall of the housing 1 (as Figure 4 shown). The input end of the air pump 112 communicates with the guiding pipe 111, and the rotating rod 8 rotates through the guiding pipe 111. A first impeller 113 is fixedly sleeved on the outer peripheral surface of the rotating rod 8 at the position inside the guiding pipe 111. A feed pipe 114 is connected and arranged on the side wall of the guiding pipe 111 near the bottom end, and the feed pipe 114 extends to the outside of the housing 1.

[0040] When the air pump 112 works, air flow enters the guiding pipe 111 through the feed pipe 114, flows inside the guiding pipe 111 and impacts the first impeller 113, driving the first impeller 113 to rotate. The first impeller 113 drives the rotating rod 8 to rotate, the rotating rod 8 drives the driving gear 9 to rotate, the driving gear 9 drives the driven gear 10 to rotate, and the driven gear 10 drives the rotating cylinder 4 to rotate, so that the ammonium tungstate solution attached to the surface of the exchange resin 5 falls under the action of centrifugal force.

[0041] A discharge port 12 is formed at the top of the partition plate 6. A collecting cylinder 13 with an open top is rotatably connected at the position corresponding to the discharge port 12 at the bottom of the partition plate 6. The lower half of the collecting cylinder 13 is provided with a hollow structure, and the molybdenum precipitate cannot pass through the collecting cylinder 13 and is left inside the collecting cylinder 13.

[0042] A guiding rod 14 is horizontally and fixedly connected inside the housing 1. A block 15 is slidably sleeved on the outer peripheral surface of the guiding rod 14. The bottom surface of the block 15 is attached to the top of the partition plate 6, and the block 15 can only move horizontally. In the initial state, the block 15 completely shields the discharge port 12 (as Figure 1 shown), and a linkage part 16 is arranged on one side of the block 15.

[0043] The linkage part 16 includes a piston 161 that is in interference fit inside the guiding pipe 111. A vertical rod 162 is fixedly connected to the bottom of the piston 161, and the vertical rod 162 slides through the inner bottom wall of the guiding pipe 111. The bottom end of the vertical rod 162 is hinged to a connecting rod 163, and the end of the connecting rod 163 away from the vertical rod 162 is hinged to the block 15.

[0044] A spring 164 is fixedly connected between the bottom of the piston 161 and the inner bottom wall of the guiding pipe 111. A U-shaped pipe 165 is fixedly connected to the side wall of the guiding pipe 111, and both ends of the U-shaped pipe 165 communicate with the guiding pipe 111. In the initial state, the piston 161 shields the bottom end of the U-shaped pipe 165, and the top end of the U-shaped pipe 165 is located above the piston 161 (as Figure 4 shown).

[0045] When the air pump 112 works, it drives the piston 161 to move upward. The piston 161 drives the vertical rod 162 to move, the vertical rod 162 drives the connecting rod 163 to move, and the connecting rod 163 drives the stopper 15 to move, so that the discharge port 12 is exposed. Until the piston 161 crosses the bottom end of the U-shaped pipe 165, the air flow can move upward through the U-shaped pipe 165, and the piston 161 no longer moves upward, so that the stopper 15 no longer moves.

[0046] Both the rotating rod 8 and the outer peripheral surface of the collecting cylinder 13 are fixedly sleeved with pulleys 17. The two pulleys 17 are connected by a belt drive. When the rotating rod 8 rotates, it drives the collecting cylinder 13 to rotate through the belt, and the ammonium tungstate solution attached to the molybdenum precipitate in the collecting cylinder 13 is thrown out by the centrifugal force.

[0047] A sliding plate 18 is arranged in the rotating cylinder 4. The outer peripheral surface of the sliding plate 18 fits with the inner wall of the rotating cylinder 4, and the solution cannot pass through the sliding plate 18. Two fixing rods 19 are vertically and fixedly connected in the rotating cylinder 4. The sliding plate 18 is slidably connected with the fixing rods 19. The two fixing rods 19 limit the sliding plate 18, so that the sliding plate 18 can only move vertically.

[0048] A reciprocating lead screw 20 is rotatably penetrated through the upper half of the housing 1. The bottom end of the reciprocating lead screw 20 is rotatably connected with the inner bottom wall of the rotating cylinder 4, and the sliding plate 18 is threadedly connected with the reciprocating lead screw 20. A driving assembly 21 is arranged on the upper half of the housing 1.

[0049] The driving assembly 21 includes two L-shaped pipes 211 fixedly penetrated through the top of the housing 1. The L-shaped pipes 211 communicate with the rotating cylinder 4, and the output ends of the first water pump 2 and the second water pump 3 are respectively communicated with the two L-shaped pipes 211. A linkage rod 212 is rotatably connected to the inner wall of the L-shaped pipe 211. The linkage rod 212 rotates through the inner side wall of the L-shaped pipe 211 and extends to the outside of the L-shaped pipe 211.

[0050] The outer peripheral surface of the linkage rod 212 is fixedly sleeved with a second impeller 213 and a driving bevel gear 214 at the positions inside and outside the corresponding L-shaped pipe 211 respectively. The outer peripheral surface of the reciprocating lead screw 20 is fixedly sleeved with a driven bevel gear 215. The driving bevel gear 214 meshes with the driven bevel gear 215.

[0051] When the first water pump 2 and the second water pump 3 work, they both impact the corresponding second impeller 213, drive the corresponding linkage rod 212 to rotate, the linkage rod 212 drives the driving bevel gear 214 to rotate, the driving bevel gear 214 drives the driven bevel gear 215 to rotate, thereby driving the reciprocating lead screw 20 to rotate, and the sliding plate 18 moves vertically back and forth. The sodium tungstate solution or the resolving agent can contact each position in the vertical direction of the ion exchange resin 5, thereby improving the utilization rate of the ion exchange resin 5, and further improving the adsorption rate of tungstate ions and the resolution rate of ammonium ions.

[0052] One of the tops of the L-shaped tubes 211 is fixedly connected with a flow dividing valve 22. The output end of the air pump 112 communicates with the input end of the flow dividing valve 22, and the output end of the flow dividing valve 22 communicates with both L-shaped tubes 211 through pipelines. The gas discharged by the air pump 112 enters the rotating cylinder 4 through the two L-shaped tubes 211, and the air flow passes through the exchange resin 5, forcing the ammonium tungstate solution in the pores of the exchange resin 5 to be discharged, further improving the collection rate of the ammonium tungstate solution.

[0053] The implementation principle of the above embodiment is as follows:

[0054] In the initial state, the discharge pipe 7 is in an open state, the block 15 shields the discharge port 12, the piston 161 shields the bottom end of the C-shaped pipe 165, and the top end of the C-shaped pipe 165 is located above the piston 161.

[0055] In the first step, start the first water pump 2 to pump the sodium tungstate solution into the corresponding L-shaped tube 211. The sodium tungstate solution drives the corresponding second impeller 213 to rotate and then enters the rotating cylinder 4. The sodium tungstate solution contacts the exchange resin 5 and passes through the exchange resin 5 and falls onto the top of the partition plate 6, and is discharged from the discharge pipe 7 out of the housing 1 and sent to the sewage treatment station for purification treatment. The tungstate ions are adsorbed on the exchange resin 5.

[0056] The rotation of the second impeller 213 drives the corresponding linkage rod 212 to rotate. The linkage rod 212 drives the driving bevel gear 214 to rotate. The driving bevel gear 214 drives the driven bevel gear 215 to rotate, thereby driving the reciprocating lead screw 20 to rotate, and the sliding plate 18 moves vertically in a reciprocating manner. The sodium tungstate solution can contact various positions of the exchange resin 5 in the vertical direction, improving the adsorption rate of tungstate ions.

[0057] Then turn off the first water pump 2 and the discharge pipe 7, and turn on the second water pump 3. The second water pump 3 pumps the analytical agent into the corresponding L-shaped tube 211, and also drives the sliding plate 18 to move vertically in a reciprocating manner. The analytical agent can contact various positions of the exchange resin 5 in the vertical direction, enabling the tungstate ions to fully exchange with the chloride ions in the analytical agent to generate ammonium tungstate solution, which falls onto the top of the partition plate 6.

[0058] The ammonium tungstate solution accumulates on the top of the partition plate 6. Then, a certain amount of ammonium sulfide is added to the ammonium tungstate solution to sulfide the molybdate ions to generate thio molybdate ions. Then, copper sulfate solution is added to generate copper thio molybdate precipitate, thereby removing trace molybdenum in the solution.

[0059] Then turn off the second water pump 3 and start the air pump 112. When the air pump 112 works, it drives the piston 161 to move upward. The piston 161 drives the vertical rod 162 to move. The vertical rod 162 drives the connecting rod 163 to move. The connecting rod 163 drives the block 15 to move, thereby exposing the discharge port 12. The ammonium tungstate solution enters the collection cylinder 13, is filtered, and then discharged to the lower half of the housing 1, and can be discharged for subsequent evaporation and crystallization steps to prepare ammonium paratungstate.

[0060] When the piston 161 passes over the bottom end of the U-shaped pipe 165, the air flow can move upward through the U-shaped pipe 165, and the piston 161 no longer moves upward, causing the stopper 15 to stop moving. While the air pump 112 is working, the air flow impacts the first impeller 113, driving the first impeller 113 to rotate. The first impeller 113 drives the rotating rod 8 to rotate, the rotating rod 8 drives the driving gear 9 to rotate, the driving gear 9 drives the driven gear 10 to rotate, and the driven gear 10 drives the rotating cylinder 4 to rotate, causing the ammonium tungstate solution attached to the surface of the exchange resin 5 to fall under the action of centrifugal force. When the rotating rod 8 rotates, it drives the collecting cylinder 13 to rotate through a belt, and the ammonium tungstate solution attached to the molybdenum precipitate in the collecting cylinder 13 is thrown out by centrifugal force.

[0061] Finally, the air pump 112 is turned off, and the piston 161 moves downward under the restoring force of the spring 164, causing the stopper 15 to cover the discharge port 12.

[0062] The embodiments of the specific implementation manners are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
