Description

Technical Field

[0001] The invention relates to the field of ore extraction, in particular to a device for extracting rubidium-cesium refined salt from low-grade lepidolite. Background Art

[0002] In the traditional process of extracting rubidium and cesium refined salt from low-grade lepidolite, uneven material mixing and sedimentation are key issues affecting the extraction efficiency. Due to the complex composition of lepidolite ore, traditional stirring equipment is difficult to ensure that all materials are evenly dispersed in the reaction solution, resulting in some materials failing to fully participate in the chemical reaction. Especially when the material density is large, it is easy to settle to the bottom of the extraction tank to form a sediment layer, further hindering the reaction. This incomplete reaction not only reduces the extraction rate of rubidium and cesium refined salt, but may also affect product quality due to the presence of residues. In addition, the traditional stirring device is not effective in cleaning the materials attached to the tank wall, making these materials unable to participate in subsequent reactions, resulting in waste of resources and increasing the workload of cleaning and maintenance.

DETAILED DESCRIPTION

[0027] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names.

[0028] Example 1

[0029] A device for extracting rubidium-cesium refined salt from low-grade lepidolite, such as Figure 1-Figure 10 As shown, it includes an extraction tank 1, a top plate 2 is installed on the top of the extraction tank 1 by bolts, a feed hopper 3 is arranged on the upper front side of the top plate 2, and an end cover is rotatably arranged on the top of the feed hopper 3, a liquid inlet 4 is arranged at the rear of the extraction tank 1, a motor 5 is arranged on the upper side of the top plate 2, the output shaft of the motor 5 is arranged downward, a stirring frame 6 is connected to the output shaft of the motor 5, and the stirring frame 6 is rotatably connected to the extraction tank 1, a discharge pipe 7 is connected to the bottom of the extraction tank 1, and a solenoid valve 8 is arranged on the discharge pipe 7, a stirring mechanism 9 is arranged inside the extraction tank 1, and the stirring mechanism 9 is used to stir the material in the extraction tank 1 so that the material is always in motion to prevent the material from sinking to the bottom, and a heating mechanism 10 is arranged on the extraction tank 1, and the heating mechanism 10 is used to increase the temperature and increase the reaction rate.

[0030] It should be noted that when extracting rubidium and cesium salt from lithium mica, the device can be used for auxiliary operation. First, the material is added to the extraction tank 1 through the feed hopper 3, and then the reaction solution is fed into the extraction tank 1 through the liquid inlet 4. After that, the motor 5 is started. The output shaft of the motor 5 will drive the stirring frame 6 to rotate, so as to mix the material and the reaction solution. In this process, the stirring mechanism 9 and the heating mechanism 10 are started synchronously. The stirring mechanism 9 can directly act on the bottom of the extraction tank 1, so that the material at the bottom can surge upward. At the same time, the heating mechanism can make the material quickly react with the reaction to improve the extraction efficiency. After the extraction is completed, the motor 5 is turned off. At this time, the extracted solution will flow outward through the discharge pipe 7, and the collection of the extracted material can be completed by controlling the solenoid valve 8.

[0031] The stirring mechanism 9 includes a lifting plate 91, four limiting rods 92 are connected in the extraction tank 1, the lifting plate 91 is slidably connected between the limiting rods 92, a reciprocating screw rod 93 is arranged at the bottom of the stirring frame 6, a connecting piece 94 is connected to the inner side of the lifting plate 91, the connecting piece 94 is slidably connected to the reciprocating screw rod 93, a scraper 95 is connected to the stirring frame 6, the scraper 95 is thin at the bottom and thick at the top, a spiral plate 96 is arranged on the scraper 95, the spiral plate 96 is used to drive the material to spirally surge, a limiting plate 97 is arranged on the lifting plate 91, and the limiting plate 97 is located on the inner side of the scraper 95.

[0032] It should be noted that as the stirring frame 6 starts to rotate, the stirring frame 6 will drive the reciprocating screw 93 to move. Under the action of the reciprocating screw 93, the connecting piece 94 will drive the lifting plate 91 to reciprocate up and down. During the up and down reciprocating movement, the lifting plate 91 will push the material at the bottom, causing the material to surge upward. At the same time, the stirring frame 6 will drive the scraper 95 and the spiral plate 96 to move synchronously during the movement, so that the material surging upward will spiral up and scrape off the material attached to the inner wall of the extraction tank 1 to avoid material residue on the inner wall of the extraction tank 1.

[0033] The heating mechanism 10 includes a mounting plate 101, and four mounting plates 101 are slidably connected to the extraction tank 1. The mounting plates 101 are inserted into the compartment of the extraction tank 1. The tops of the mounting plates 101 are provided with handles. The inner sides of the mounting plates 101 are connected to heating tubes 102, and the upper parts of the mounting plates 101 are connected to sealing blocks 103.

[0034] It should be noted that during the extraction process, the heating tube 102 is started synchronously. The heat generated by the heating tube 102 will increase the temperature in the extraction tank 1, thereby allowing the material and the reaction solution to react and fuse faster. When no maintenance or replacement is required, the handle can be pulled upwards so that the mounting plate 101 drives the heating plate out of the extraction tank 1, thereby completing the removal.

[0035] Example 2

[0036] It also includes a vibration mechanism 11, which includes an installation box 111. The installation box 111 is arranged on the right side of the extraction tank 1, and a vibration component 112 is installed in the installation box 111. The extraction tank 1 is placed on a mounting base 113, and a shock absorbing component 114 is arranged on the mounting base 113. The shock absorbing component 114 acts on the extraction tank 1.

[0037] It should be noted that during the operation of the device, as the stirring frame 6 starts to rotate, the vibration component 112 is started synchronously, and the vibration component 112 begins to generate vibration force, causing the extraction tank 1 to begin to vibrate slightly. At the same time, under the action of the shock-absorbing component 114, the extraction tank 1 can maintain a small amplitude of shaking, thereby assisting the material in the extraction tank 1 to accelerate the reaction.

[0038] It also includes a limiting mechanism 12, which includes a mounting member 121. Four groups of mounting members 121 are connected to the extraction tank 1. The mounting members 121 are all rotatably connected to limiting members 122. The limiting members 122 are used to lock and limit the mounting plate 101. A torsion spring 123 is connected between the limiting member 122 and the adjacent mounting member 121.

[0039] It should be noted that in order to improve the stability of the mounting plate 101, the mounting plate 101 is limited and blocked by the limiting member 122. When the mounting plate 101 needs to be taken out, the limiting member 122 needs to be flipped outward first so that the torsion spring 123 is deformed under the force. At this time, the limiting member 122 no longer blocks the mounting plate 101, and the mounting plate 101 can be directly taken out.

[0040] It also includes a pressure relief mechanism 13, which includes a wide-mouth structure 131 and a narrow-mouth structure 132. A pressure relief pipe is arranged on the lifting plate 91, and the wide-mouth structure 131 and the narrow-mouth structure 132 are arranged inside the pressure relief pipe. The wide-mouth structure 131 and the narrow-mouth structure 132 cooperate to make the internal air pressure of the extraction tank 1 match the external air pressure to prevent pressure difference.

[0041] It also includes a reinforcement mechanism 14 , which includes a reinforcement plate 141 . Three groups of reinforcement plates 141 are connected to the bottom of the spiral plate 96 . Through holes 142 are opened on the reinforcement plates 141 . The reinforcement plates 141 are used to improve the material guiding ability of the spiral plate 96 .

[0042] It should be understood that the above description is only for exemplary purposes and is not meant to limit the present invention. Those skilled in the art will appreciate that variations of the present invention will be included within the scope of the claims herein.
