Description

Technical Field

[0001] This utility model relates to the field of leaching solution preparation technology, and in particular to an ionic rare earth leaching solution preparation device. Background Technology

[0002] In the field of rare earth resource development and utilization, ionic rare earths have attracted much attention due to their unique occurrence state and extraction method. In the extraction process of ionic rare earths, the preparation of leachate is a crucial preliminary step. The quality of the leachate directly affects important indicators such as the leaching rate and extraction purity of rare earth elements. In the leachate preparation process, an appropriate amount of water needs to be added to the preparation tank first, then an appropriate amount of magnesium sulfate solid powder is added, and finally the mixture is stirred by a stirring device.

[0003] In current solution preparation devices, when magnesium sulfate powder is added to the leachate, the magnesium sulfate needs a certain amount of time to dissolve, and some of the magnesium sulfate powder will float on the surface of the water. The floating magnesium sulfate powder may affect the dissolution and mixing effect, and thus may affect the solution preparation efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an ionic rare earth leachate preparation device that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An ion-type rare earth leaching solution preparation device includes: a preparation tank, and further includes: a cover threadedly connected to the preparation tank; a stirring shaft rotatably mounted on the cover; water spray pipes symmetrically fixedly connected to the upper side of the stirring shaft; a plurality of second water spray nozzles equidistantly arranged on the lower side of the water spray pipes; a stirring assembly mounted on the stirring shaft; a motor fixedly mounted on the cover, with the output end of the motor fixedly connected to the stirring shaft; a liquid delivery assembly for conveying liquid from the preparation tank to the stirring shaft; a liquid outlet pipe located on the lower side of the preparation tank, and a solenoid valve installed inside the liquid outlet pipe; and a water inlet located on the upper side of the cover.

[0007] To facilitate the circulation of liquid into the stirring shaft, the liquid delivery assembly further includes a circulation pump fixed to one side of the liquid preparation tank. A liquid extraction pipe is fixedly connected between the liquid extraction end of the circulation pump and the bottom of the liquid preparation tank. A water inlet ring is fixedly connected to the cover. A water inlet communicating with the water inlet ring is opened on the stirring shaft. A liquid inlet pipe is provided between the liquid outlet end of the circulation pump and the water inlet ring.

[0008] To facilitate the stirring of the liquid in the mixing tank, the stirring assembly further includes multiple stirring blades fixedly connected to the stirring shaft.

[0009] Preferably, the stirring shaft has multiple sets of equidistantly arranged first water spray nozzles.

[0010] To facilitate the addition of magnesium sulfate powder, preferably, the cover is provided with a feeding hopper, and an extension pipe is fixedly connected to the lower side of the feeding hopper, with the lower end of the extension pipe located below the water spray pipe.

[0011] To further improve the mixing effect of powder and water, a bubble generating tube is fixedly connected inside the mixing tank, and the bubble generating tube is set inside the stirring shaft. A baffle is fixedly connected inside the stirring shaft, and a connecting port is provided on the baffle. A one-way valve is provided in the connecting port. An air pump is fixedly connected to the lower side of the mixing tank, and an air inlet pipe is fixedly connected between the exhaust end of the air pump and the bubble generating tube.

[0012] Compared with the prior art, this utility model provides an ionic rare earth leachate preparation device, which has the following beneficial effects:

[0013] 1. This ion-type rare earth leaching solution preparation device uses a circulating pump to draw liquid from the bottom of the preparation tank through a suction pipe, then transports it to the water inlet ring through the inlet pipe, and then enters the stirring shaft through the water inlet on the stirring shaft. Finally, it is sprayed out from multiple second water spray nozzles on the lower side of the spray pipe, which disperses the powder raw materials on the water surface, allowing them to come into more full contact with the liquid, effectively improving their dissolution and mixing effects.

[0014] 2. This ion-type rare earth leaching solution preparation device operates by using an air pump to deliver air through an air inlet pipe to a bubble generating pipe. The bubble generating pipe generates bubbles, which agitate the liquid as they rise, aiding in mixing. The mixed liquid inside the stirring shaft is sprayed out through multiple first water spray nozzles. The water sprayed from the first water spray nozzles has a certain impact force, and the rotation of the stirring shaft can improve the stirring and mixing effect of the liquid in the preparation tank, thereby effectively improving its preparation efficiency.

[0015] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model disperses the powdered raw materials on the water surface by spraying liquid from multiple second water nozzles, allowing them to come into more full contact with the liquid, effectively improving their dissolution and mixing effects, and thus effectively improving their liquid preparation efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figures 1-4 An ion-type rare earth leaching solution preparation device includes: a preparation tank 1, and further includes: a cover 101 threadedly connected to the preparation tank 1; a stirring shaft 2 rotatably mounted on the cover 101; a water spray pipe 209 symmetrically fixedly connected to the upper side of the stirring shaft 2; a plurality of second water spray nozzles 210 equidistantly arranged on the lower side of the water spray pipe 209; a stirring assembly mounted on the stirring shaft 2; a motor 203 fixedly mounted on the cover 101, and the output end of the motor 203 fixedly connected to the stirring shaft 2; a liquid delivery assembly for conveying the liquid in the preparation tank 1 to the stirring shaft 2; a liquid outlet pipe 105 located on the lower side of the preparation tank 1, and a solenoid valve is provided inside the liquid outlet pipe 105; and a water inlet 104 located on the upper side of the cover 101.

[0023] Among them, the water spray pipe 209 is located on the upper side of the liquid surface.

[0024] The infusion assembly includes a circulation pump 207 fixed to one side of the mixing tank 1. A suction pipe 208 is fixedly connected between the suction end of the circulation pump 207 and the bottom of the mixing tank 1. A water inlet ring 205 is fixedly connected to the cover 101. A water inlet 204 communicating with the water inlet ring 205 is opened on the stirring shaft 2. An inlet pipe 206 is provided between the outlet end of the circulation pump 207 and the water inlet ring 205.

[0025] The stirring assembly includes multiple stirring blades 202 that are fixedly connected to the stirring shaft 2.

[0026] A feed hopper 102 is provided on the cover 101, and an extension pipe 103 is fixedly connected to the lower side of the feed hopper 102, with the lower end of the extension pipe 103 located below the water spray pipe 209.

[0027] First, add an appropriate amount of water into the mixing tank 1 through the water inlet 104, then start the motor 203. The motor 203 drives the stirring shaft 2 to rotate, and the stirring blades 202 on the stirring shaft 2 stir the water in the mixing tank 1. Then, add the powder raw material into the mixing tank 1 through the feed hopper 102 on the cover 101. The raw material falls into the mixing tank 1 through the extension pipe 103 and is stirred by the stirring blades 202 on the stirring shaft 2 to mix the powder with the water.

[0028] Turn on the circulation pump 207. The circulation pump 207 works to draw the liquid from the bottom of the liquid preparation tank 1 into the liquid extraction pipe 208, and then deliver it to the water inlet ring 205 through the liquid inlet pipe 206. The liquid then enters the stirring shaft 2 through the water inlet 204 on the stirring shaft 2, and finally sprays it out from the multiple second water spray nozzles 210 on the lower side of the water spray pipe 209. This disperses the powder raw materials on the water surface, allowing them to come into more full contact with the liquid, effectively improving their dissolution and mixing effects.

[0029] Example 2: Refer to Figures 1-4 An ionic rare earth leachate preparation device is basically the same as that in Example 1, except that multiple sets of equidistant first water spray nozzles 201 are provided on the stirring shaft 2.

[0030] A bubble generating tube 4 is fixedly connected inside the liquid mixing tank 1, and the bubble generating tube 4 is located inside the stirring shaft 2. A partition 3 is fixedly connected inside the stirring shaft 2. A connecting port 301 is provided on the partition 3. A one-way valve is provided inside the connecting port 301. An air pump 401 is fixedly connected to the lower side of the liquid mixing tank 1. An air inlet pipe 402 is fixedly connected between the exhaust end of the air pump 401 and the bubble generating tube 4.

[0031] When the air pump 401 is working, it delivers air to the bubble generating pipe 4 through the air inlet pipe 402. The bubble generating pipe 4 generates bubbles, which agitate the liquid as they rise, aiding in mixing. The mixed liquid in the stirring shaft 2 is sprayed out through multiple first water spray nozzles 201. The water sprayed out by the first water spray nozzles 201 has a certain impact force, and the rotation of the stirring shaft 2 can improve the stirring and mixing effect of the liquid in the mixing tank 1, thereby effectively improving its mixing efficiency.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
