Description

Technical Field

[0001] The utility model relates to the technical field of metal extraction devices, and particularly relates to a mother liquor adsorption tower. Background Art

[0002] Gallium is a by-product in the industrial treatment processes of sphalerite, pyrite, bauxite, and germanite. Gallium is a rare element mainly used in the semiconductor industry. The extraction method of gallium is usually to recover it from Bayer mother liquor. There are various methods to recover gallium from Bayer mother liquor, such as extraction method, amalgamation method, electrolysis method, and chemical enrichment method, etc. However, due to the high cost of the extraction method, a large amount of extractant, aluminum hydroxide, and alkali are consumed, and organic substances are introduced into the alumina production process; the amalgamation method has the disadvantages of large mercury consumption and mercury pollution; the electrolysis method has the disadvantage of serious pollution; there are many methods for the chemical enrichment method, but its operation is complex, the separation effect of gallium and aluminum is poor, and the recovery rate is not high.

[0003] Referring to the CN114920875B - A method for preparing a chelating resin for adsorbing gallium previously applied by the applicant, the chelating resin is used to adsorb and purify gallium elements in the mother liquor. During operation, the chelating resin particles are put into the adsorption tower to adsorb gallium in the mother liquor. Currently, the chelating resin particles in the adsorption tower are manually put in, which has a high dependence cost on labor. Moreover, manually putting in the chelating resin particles is very dangerous, and the input amount of chelating resin particles cannot be adjusted according to the amount of mother liquor in the adsorption tower, thus the gallium recovery rate cannot be improved, resulting in an increase in production costs. Content of the Utility Model

[0004] The utility model aims to provide a mother liquor adsorption tower to provide an adsorption tower that replaces manual input of chelating resin particles.

[0005] To solve the above problems, the utility model provides the following technical solutions:

[0006] A mother liquor adsorption tower includes a tower body. The tower body is fixedly connected to an inverted L-shaped feed pipe. The feed pipe is provided with a fan. The tower body is fixedly provided with a bracket. The bracket is fixedly provided with an outer groove connected to the feed pipe. The top of the outer groove is fixedly provided with an inner groove. The bottom of the inner groove is provided with an arc-shaped discharge port. The bracket is fixedly provided with a motor. The motor drives a feed disk that abuts against the discharge port. The feed disk is provided with a plurality of loading grooves along the circumferential direction that are alternately connected to the discharge port.

[0007] The working principle and beneficial effects of the utility model:

[0008] When this solution is used, the mother liquor is introduced into the adsorption tower, and the chelating resin particles are loaded into the inner tank. At this time, one loading tank on the feeding tray is aligned with the discharge port, and the chelating resin particles flow into the loading tank. Subsequently, the motor drives the feeding tray to rotate, and the loading tank filled with chelating resin particles rotates to face the bottom of the outer tank, pouring the chelating resin particles into the outer tank and flowing into the feeding pipe through the bottom of the outer tank. Moreover, at this time, the fan in the feeding pipe starts. Since the chelating resin particles are small and light in weight, the wind generated by the fan blows the chelating resin particles into the tower body, thus realizing the input of the chelating resin particles. At this time, the next loading tank rotates to align with the discharge port.

[0009] In this solution, since the volume of the loading tank is fixed, the purpose of quantitatively inputting chelating resin particles each time can be achieved, which is conducive to improving the gallium recovery rate. And automatic feeding is realized through the fan, the feeding pipe, the motor and the feeding tray, and the feeding time interval is controlled by controlling the operation of the motor.

[0010] Optimally, the motor is specifically a servo motor. The servo motor has the function of accurately controlling the rotation angle of the output shaft, and further controls the loading tank to accurately rotate to align with the discharge port.

[0011] Optimally, the volumes of multiple loading tanks are different. Different amounts of chelating resin particles are added to the adsorption tower through multiple loading tanks with different volumes, so as to add appropriate amounts of chelating resin particles according to different amounts of mother liquor, and improve the gallium recovery rate.

[0012] Optimally, the number of loading tanks is 3, and the angular interval between adjacent loading tanks in the circumferential direction is 120 degrees. Three feedings are realized through 3 loading tanks.

[0013] Optimally, the tower body is provided with a pressure relief valve. When the pressure inside the tower body is high, the pressure relief valve opens for exhaust.

[0014] Optimally, a vibration motor is fixedly arranged in the inner tank. The vibration motor is used to vibrate the inner tank to promote the flow of chelating resin particles. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In the following statements, orientation terms such as "left", "right", "up", and "down" are based on the orientation shown in the drawings. In practice, if the corresponding structures are changed in the same direction based on the orientation and the relative positions remain unchanged, it does not affect the implementation of the solution.

[0020] Embodiment: A mother liquor adsorption tower, as Figure 1 and Figure 2 shown, includes a tower body 1. The tower body 1 is fixedly connected to an inverted L-shaped feed pipe 4. A fan 5 is fixedly provided on the left side of the feed pipe 4. The tower body 1 is fixedly provided with a support 2. The support 2 is fixedly provided with an outer tank 3 connected to the feed pipe 4. The top of the outer tank 3 is fixedly provided with an inner tank 6. The bottom of the inner tank 6 is provided with an arc-shaped discharge port. The support 2 is fixedly provided with a motor 9. The motor 9 drives a feed tray 7 that abuts against the discharge port. The feed tray 7 is provided with 3 loading tanks 8 that are alternately connected to the discharge port along the circumferential direction. The motor 9 is specifically a servo motor.

[0021] When this solution is used, the mother liquor is introduced into the adsorption tower, and the chelating resin particles are loaded into the inner tank 6. At this time, the top loading tank 8 on the feed tray 7 is aligned with the discharge port, and the chelating resin particles flow into the loading tank 8. Subsequently, the motor 9 drives the feed tray 7 to rotate. The loading tank 8 filled with chelating resin particles rotates to face the bottom of the outer tank 3, and the chelating resin particles are poured into the outer tank 3 and flow into the feed pipe 4 through the bottom of the outer tank 3. And at this time, the fan 5 in the feed pipe 4 is started. Since the chelating resin particles are small and light in weight, the wind generated by the fan 5 blows the chelating resin particles into the tower body 1, thereby realizing the input of the chelating resin particles. At this time, the next loading tank 8 rotates to be aligned with the discharge port.

[0022] In this solution, since the volume of the loading tank 8 is fixed, the purpose of quantitatively inputting chelating resin particles each time can be achieved, which is beneficial to improving the gallium recovery rate; and automatic feeding is realized through the fan 5, feed pipe 4, motor 9 and feed tray 7, and the feeding time interval is controlled by controlling the operation of the motor 9.
