Description

Technical Field

[0001] This utility model relates to the field of compound processing equipment technology, and in particular to lithium carbonate hydrocarbonation equipment. Background Technology

[0002] Lithium carbonate production mainly comes from lithium resources in ore and brine in salt lakes. The process of extracting lithium from ore involves a series of complex steps, including beneficiation, roasting, and leaching, to obtain crude lithium carbonate. However, in many practical applications, it is necessary to further convert lithium carbonate into other lithium compounds to meet specific production requirements. While existing lithium carbonate hydrocarbonation equipment can generally meet daily needs, there are still some shortcomings that require improvement.

[0003] Most commercially available lithium carbonate hydrocarbonation equipment uses an integrated reactor for preparation. However, in actual use, after the lithium bicarbonate is prepared in the reactor, the equipment needs to be stopped, the lithium bicarbonate in the reactor needs to be removed, and a lot of time needs to be spent cleaning the inside of the reactor before it can be reused. This intermittent operation not only results in relatively low production efficiency, making it unsuitable for large-scale continuous production, but also makes the cleaning and maintenance of the equipment troublesome and inconvenient to use. Therefore, we propose a lithium carbonate hydrocarbonation equipment to solve the above problems. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a lithium carbonate hydrocarbonation device to solve the technical problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A lithium carbonate hydrocarbonation device includes a base, a side column mounted on the left side of the base, a lead screw rotatably connected to the top of the side column, a guide rod fixed to the right side of the lead screw, a movable seat external to the lead screw and guide rod, a threaded sleeve and a guide sleeve installed inside the movable seat, a stirring motor mounted on the right outer wall of the movable seat, a stirring rod mounted at the output end of the stirring motor, a cover plate rotatably connected to the middle of the stirring rod, an air inlet provided on the cover plate, a collar mounted on the lower outer wall of the lead screw, multiple sets of throttle handles mounted externally to the collar, a rotating column mounted on the right end of the base, a rotating sleeve rotatably connected to the outside of the rotating column, brackets mounted on both sides of the rotating sleeve, reaction tanks mounted inside each bracket, and a steering and positioning assembly provided at the top of the rotating column.

[0007] As an improved technical solution, the steering positioning assembly includes a sleeve fixed to the top of the rotating column and a movable plate disposed inside the sleeve. Positioning pins are installed at both the front and rear ends of the bottom of the movable plate. Two sets of positioning holes are opened at the top of the rotating sleeve, and the bottom ends of the two sets of positioning pins can be inserted into the positioning holes. A pull handle is connected to the middle of the top of the movable plate through a connecting rod, and a return spring is wound around the outside of the connecting rod.

[0008] As an improved technical solution, the input terminal of the stirring motor is electrically connected to an external controller via a wire.

[0009] As an improved technical solution, a positioning strip is installed on the outer wall of the reaction vessel, and a groove corresponding to the positioning strip is opened on the bracket, so that the positioning strip on the reaction vessel can be inserted into the groove on the bracket.

[0010] As an improved technical solution, the two ends of the return spring are respectively connected to the outer wall of the movable plate and the top of the inner wall of the sleeve, and the movable plate is elastically connected to the top of the inner wall of the sleeve through the return spring.

[0011] As an improved technical solution, the inner diameter of the two sets of positioning holes on the rotating sleeve is the same as the outer diameter of the positioning post, and the included angle between the two sets of positioning holes is 180 degrees.

[0012] As an improved technical solution, the outer wall of the movable plate is fully fitted with the inner wall of the sleeve, and the movable plate and the sleeve are slidably connected.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are: I. This utility model features a rotatable sleeve mounted on a base, with two sets of brackets installed on the sleeve. Two reaction vessels can be placed within the brackets, with lithium carbonate and water pre-filled inside. The brackets move the reaction vessels to a position below the stirring rod, which then moves the cover plate to the top of the reaction vessels, sealing the interior. A stirring motor drives the stirring rod to agitate the interior of the reaction vessels. Under the action of the stirring rod, carbon dioxide, lithium carbonate, and water in the reaction vessels fully react to produce lithium bicarbonate. By rotating the sleeve, the positions of the two reaction vessels can be quickly switched, thus shortening the device's downtime. The separate reaction vessels allow for rapid transport of the produced lithium bicarbonate and facilitate subsequent cleaning of the interior, effectively improving the convenience of the device during use.

[0014] II. This utility model has a movable plate that can be raised and lowered installed at the top of the rotating column. Under the elastic force of the return spring, the movable plate can drive two sets of positioning columns to insert into two sets of positioning holes on the rotating sleeve, which can quickly form a turning and limiting effect on the rotating sleeve. This can effectively prevent the reaction vessel from shifting during the preparation process and improve the stability of the device during use. Attached Figure Description

[0021] Figures 1 to 4 As shown, this embodiment provides a lithium carbonate hydrocarbonation device, including a base 1, a side column 2 installed on the left side of the base 1, a lead screw 3 rotatably connected to the top of the side column 2, a guide rod 4 fixed to the right side of the lead screw 3, a movable seat 5 provided outside the lead screw 3 and the guide rod 4, a threaded sleeve 6 and a guide sleeve 7 installed inside the movable seat 5, a stirring motor 8 installed on the outer wall of the right side of the movable seat 5, a stirring rod 9 installed at the output end of the stirring motor 8, a cover plate 24 rotatably connected to the middle of the stirring rod 9, an air inlet 25 provided on the cover plate 24, a collar 10 installed on the outer wall of the lower end of the lead screw 3, multiple sets of throttles 11 installed outside the collar 10, a rotating column 12 installed on the right end of the base 1, a rotating sleeve 13 rotatably connected to the outside of the rotating column 12, brackets 14 installed on both sides of the rotating sleeve 13, reaction tanks 15 installed inside the brackets 14, and a steering positioning component provided at the top of the rotating column 12.

[0022] By installing a rotatable sleeve 13 on the base 1 and two sets of brackets 14 on the sleeve 13, two sets of reaction tanks 15 can be placed in the brackets 14. Lithium carbonate and water are prepared in advance in the reaction tanks 15. The brackets 14 move the reaction tanks 15 to below the stirring rod 9, and then the stirring rod 9 moves the cover plate 24 to the top of the reaction tanks 15 to seal the inside of the reaction tanks 15. The stirring motor 8 drives the stirring rod 9 to stir the inside of the reaction tanks 15. Under the action of the stirring rod 9, the carbon dioxide in the reaction tanks 15 fully contacts and reacts with the lithium carbonate and water to produce lithium bicarbonate. By rotating the sleeve 13, the positions of the two sets of reaction tanks 15 can be quickly switched, thereby shortening the downtime of the device. The split-type reaction tanks 15 can be quickly transported to produce lithium bicarbonate and are easy to clean the inside of the reaction tanks 15 later, which effectively improves the convenience of the device during use.

[0023] In other embodiments, the steering positioning assembly includes a sleeve 17 fixed to the top of the rotating column 12 and a movable plate 18 disposed inside the sleeve 17. Positioning pins 19 are installed at both the front and rear ends of the bottom of the movable plate 18. The top of the rotating sleeve 13 has two sets of positioning holes 20. The bottom ends of the two sets of positioning pins 19 can be inserted into the positioning holes 20. A pull handle 22 is connected to the middle of the top of the movable plate 18 through a connecting rod 21. A return spring 23 is wound around the outside of the connecting rod 21. The rotating column 12 is equipped with a liftable movable plate 18, which allows the movable plate 18 to drive the two sets of positioning columns 19 to be inserted into the two sets of positioning holes 20 on the rotating sleeve 13 under the elastic force of the return spring 23. This quickly forms a turning and limiting effect on the rotating sleeve 13, which can effectively prevent the reaction vessel 15 from shifting during the preparation process and improve the stability of the device during use.

[0024] In other embodiments, the input terminal of the stirring motor 8 is electrically connected to an external controller via a wire; This design allows an external controller to control the start and stop of the stirring rod 9 in real time, ensuring that the stirring motor 8 can drive the stirring rod 9 to rotate normally.

[0025] like Figure 3 As shown, a positioning strip 16 is installed on the outer wall of the reaction vessel 15, and a groove corresponding to the positioning strip 16 is provided on the bracket 14. The positioning strip 16 on the reaction vessel 15 can be inserted into the groove on the bracket 14. This design allows the reaction vessel 15 to drive the positioning strip 16 into the groove in the bracket 14, thereby effectively preventing the reaction vessel 15 from rotating within the bracket 14.

[0026] like Figure 4 As shown, the two ends of the return spring 23 are respectively connected to the outer wall of the movable plate 18 and the top of the inner wall of the sleeve 17, and the movable plate 18 is elastically connected to the top of the inner wall of the sleeve 17 through the return spring 23. This design allows the return spring 23 outside the connecting rod 21 to continuously apply a downward elastic force to the movable plate 18, so that the movable plate 18 can drive the two sets of positioning pins 19 to move downward quickly under the elastic force of the return spring 23 and insert into the two sets of positioning holes 20 on the rotating sleeve 13.

[0027] like Figure 4 As shown, the inner diameter of the two sets of positioning holes 20 on the rotating sleeve 13 is the same as the outer diameter of the positioning post 19, and the included angle between the two sets of positioning holes 20 is 180 degrees. With this design, when the movable plate 18 drives the two sets of positioning pins 19 to insert into the two sets of positioning holes 20 on the rotating sleeve 13, the two sets of positioning pins 19 can form a stable steering and limiting effect on the rotating sleeve 13, preventing the reaction vessel 15 from shifting during the preparation process.

[0028] like Figure 4 As shown, the outer wall of the movable plate 18 is fully fitted with the inner wall of the sleeve 17, and the movable plate 18 and the sleeve 17 are slidably connected. This design effectively prevents the movable plate 18 from shaking within the positioning columns 19 when the movable plate 18 moves upward, thus improving the stability of the device during use.

[0029] This utility model provides a lithium carbonate hydrocarbonation device, the specific working principle of which is as follows: When using this equipment, first add lithium carbonate and water to the reaction tank 15. Then, move the bracket 14 to position the reaction tank 15 directly below the stirring rod 9. Next, rotate the handle 11 on the outside of the collar 10 to rotate the lead screw 3. This allows the movable seat 5 to move the stirring motor 8 downwards under the combined action of the thread of the threaded sleeve 6 and the guide sleeve 7. The stirring motor 8 then drives the stirring rod 9 into the reaction tank 15, and the stirring rod 9 moves the cover plate 24 to cover the reaction tank 15. Then, connect the air inlet 25 to the carbon dioxide cylinder through the air pipe to allow carbon dioxide gas to enter the reaction tank 15. Then, start the stirring motor 8 to rotate the stirring rod 9, allowing the stirring rod 9 to fully stir the lithium carbonate inside the reaction tank 15. Under the action of the stirring rod 9, the carbon dioxide reacts fully with the lithium carbonate and water to produce lithium bicarbonate. Then, reverse the rotation of the collar 10. Turn the handle 11 to raise the movable seat 5 and drive the stirring motor 8, allowing the stirring rod 9 to completely leave the inside of the reaction vessel 15. Then pull the handle 22 upward, causing the movable plate 18 to move the two sets of positioning pins 19 upward, so that the two sets of positioning pins 19 leave the two sets of positioning holes 20 on the rotating sleeve 13. Then rotate the rotating sleeve 13, causing the two sets of brackets 14 to rotate 180 degrees, so that the two sets of reaction vessels 15 can be quickly swapped. This allows the reaction vessel 15 to carry lithium bicarbonate for overall transportation and facilitates subsequent cleaning of the reaction vessel 15. Then release the tension on the handle 22, allowing the return spring 23 to release its elasticity and push the movable plate 18 to drive the two sets of positioning pins 19 into the two sets of positioning holes 20 on the rotating sleeve 13, forming a steering limit effect on the rotating sleeve 13. Then repeat the above operation to prepare lithium bicarbonate in the reaction vessel 15. The operation is now complete.

[0030] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
