Description

Technical Field

[0001] This utility model relates to the field of gallium production equipment technology, specifically to a liquid level regulating device for high-purity gallium production. Background Technology

[0002] High-purity gallium has wide applications in semiconductors, optoelectronics, and other fields. The treatment of the mother liquor is crucial in its production process, as it contains valuable components such as gallium. Properly controlling the relevant aspects of the mother liquor process is of great significance for the yield and quality assurance of high-purity gallium.

[0003] Utility model patent CN218306419U discloses a mother liquor tank for gallium production with controllable liquid level. This mother liquor tank includes a tank body, the inner wall of which is coated with an anti-corrosion coating, and a support frame welded to the bottom. An observation port is embedded in the surface of the tank body, and a filter assembly is welded to the inner wall. Adjustment components are welded to both ends of the outer wall of the tank body, and a top cover is installed at the top. A fixing rod is fixedly connected to the inner wall of the top cover, and a liquid inlet pipe is welded to the top of the top cover. A drain assembly is installed at the bottom of the tank body, and a liquid level control assembly is installed at one end of the outer wall. The top cover and fixing rod allow for easy removal of the top cover after use, facilitating cleaning of the inner wall of the tank body.

[0004] The mother liquor tank for gallium production with controllable liquid level uses an electronically controlled bidirectional water pump with start-stop regulation. Since the mother liquor is consumed during the reaction, the bidirectional water pump needs to be frequently started to add more. This not only causes large fluctuations in the liquid level due to the start and stop of the water pump, but also leads to problems such as control failure caused by sensor malfunction and shortened service life of the water pump due to frequent start and stop. It is difficult to meet the requirements of high-purity gallium production for liquid level stability and equipment reliability. In view of this, we propose a liquid level regulation device for high-purity gallium production. Utility Model Content

[0005] The purpose of this invention is to provide a liquid level regulating device for high-purity gallium production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-purity gallium production liquid level regulating device includes a mother liquor tank with a lid at the top. A storage assembly for storing excess gallium-containing mother liquor is located on the outside of the mother liquor tank. The storage assembly includes a storage tank and a transfer pump mounted on the lid. The transfer pump transfers mother liquor from the mother liquor tank to the storage tank. A liquid level regulating mechanism is located between the bottom of the storage tank and the bottom of the mother liquor tank. The liquid level regulating mechanism includes a delivery pipe, a control component sleeved within the delivery pipe and moving synchronously along the mother liquor surface, and a... An adjusting component for limiting the upward position of a control component, the control component includes a float sleeve and a float column. The bottom of the float sleeve has a cavity, and the top of the float sleeve has a conical hole. The bottom end of the float column is connected to a sealing cone, which extends into the cavity. When the liquid level in the mother liquor tank is lower than the set liquid level, the sealing cone moves away from the conical hole, causing the conical hole to open. At this time, the mother liquor in the storage tank flows downward through the conical hole into the mother liquor tank. When the liquid level in the mother liquor tank reaches the set height, the float column floats up and drives the sealing cone to seal the conical hole.

[0008] Preferably, the top of the tank cover is connected to several feed pipes, the bottom of the mother liquor tank is connected to a discharge pipe, the mother liquor tank is fixed in the fixing frame, and a side frame for installing the storage tank is fixed at the top of the side end of the fixing frame.

[0009] In this setup, the feed pipe facilitates the addition of mother liquor or reagents, the discharge pipe facilitates the discharge of mother liquor, and the fixing frame and side frame are used to fix the mother liquor tank and storage tank, respectively.

[0010] Preferably, the inlet end of the delivery pump is connected to the interior of the mother liquor tank via a pipe, and the outlet end of the delivery pump is connected to the top of the storage tank via a pipe.

[0011] In this setup, the transfer pump can transfer excess mother liquor from the mother liquor tank to the storage tank for storage.

[0012] Preferably, the top end of the infusion tube is connected to the bottom end of the storage tank, the bottom end of the infusion tube is connected to the bottom of the mother liquor tank, and several horizontal tubes are connected at equal intervals along the axial direction on the outer circumferential surface of the infusion tube. The outer ends of the horizontal tubes are closed, and several adjusting components are respectively sleeved in multiple horizontal tubes.

[0013] In this setup, the infusion tubing forms a mother fluid flow channel, and the horizontal tube provides an installation location for the adjustment components.

[0014] Preferably, the outer peripheral surface of the float sleeve is provided with a plurality of sealing lips, which play a sealing role between the inner wall of the infusion tube and the float sleeve.

[0015] In this configuration, the sealing lip prevents the mother liquor from leaking through the gap between the float sleeve and the inner wall of the infusion tube.

[0016] Preferably, the bottom end of the float is fixed with several support plates in an annular shape at equal intervals. When the float moves downward, the support plates support the bottom end of the float and the top of the float sleeve.

[0017] In this configuration, the support plate prevents the bottom of the float from blocking the top of the cone hole, ensuring that the cone hole can be opened normally.

[0018] Preferably, the top of the sealing cone is provided with a connecting rod, and the top of the connecting rod is fixedly connected to the bottom of the float.

[0019] In this configuration, the connecting rod secures the float and the sealing cone, allowing the sealing cone to move along with the float under the action of the connecting rod.

[0020] Preferably, the adjusting component includes a stop post that can move along the horizontal tube and a pull rod fixed to the tail end of the stop post. The pull rod is T-shaped, with the T-shaped end of the pull rod penetrating the end of the horizontal tube and fixedly connected to the stop post. The T-shaped head of the pull rod is a gripping end. When the pull rod is pushed towards the infusion tube, the pull rod drives the stop post to slide inward along the horizontal tube, so that the end of the stop post extends into the inside of the infusion tube. At this time, the end of the stop post is protruding inward inside the infusion tube, so that the stop post can block the upward movement of the float sleeve. By adjusting the position of the stop post on different horizontal tubes, the maximum upward movement height of the float sleeve can be set. When the pull rod is pulled outward, the pull rod drives the stop post to slide outward along the horizontal tube. At this time, the stop post can avoid the upward movement of the control component.

[0021] In this setting, the maximum upward floating height of the float sleeve can be set by adjusting the position of the baffle, thereby setting the liquid level height inside the mother liquor tank.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This high-purity gallium production liquid level regulating device achieves automatic compensation and precise control of the liquid level when the mother liquor is consumed through the mechanical linkage between the float sleeve and the float column and the manual adjustment component of the baffle column. It can dynamically adjust the replenishment flow rate according to the real-time changes in the liquid level without the need for electric drive, avoiding equipment damage caused by frequent start and stop of the water pump, and also supports manual precise setting of the liquid level height.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-6The high-purity gallium production liquid level regulating device includes a mother liquor tank 100, with a tank cover 110 at the top. Several inlet pipes 111 are connected to the top of the tank cover 110, allowing mother liquor or reagents to be added to the mother liquor tank 100. A discharge pipe 120 is connected to the bottom of the mother liquor tank 100 for discharging the mother liquor from the tank. The mother liquor tank 100 is fixed within a mounting frame 130, which supports and secures the mother liquor tank 100. A storage assembly 200 for storing excess gallium-containing mother liquor is provided on the outside of the mother liquor tank 100. The storage assembly 200 includes a storage tank 210 and a transfer pump 220 installed on the top of the tank cover 110. A side frame 140 for installing the storage tank 210 is fixed at the top of the side end of the fixing frame 130. The side frame 140 provides installation support for the storage tank 210. The inlet end of the transfer pump 220 is connected to the inside of the mother liquor tank 100 via a pipe, and the outlet end of the transfer pump 220 is connected to the top of the storage tank 210 via a pipe. By starting the transfer pump 220, the transfer pump 220 can transport the mother liquor in the mother liquor tank 100 to the storage tank 210, thereby realizing the storage of excess mother liquor.

[0036] like Figures 1-3 As shown, in this utility model, a liquid level adjustment mechanism 300 is provided between the bottom end of the storage tank 210 and the bottom of the mother liquor tank 100. The liquid level adjustment mechanism 300 is used to realize the automatic adjustment of the liquid level in the mother liquor tank 100. The liquid level adjustment mechanism 300 includes a delivery pipe 310, a control component 320 sleeved in the delivery pipe 310 and moving synchronously along the surface of the mother liquor, and an adjustment component 330 for limiting the upward floating position of the control component 320.

[0037] like Figure 1 and Figure 2 As shown, specifically, the top end of the infusion tube 310 is connected to the bottom end of the storage tank 210, and the bottom end of the infusion tube 310 is connected to the bottom of the mother liquor tank 100, so that a mother liquor flow channel is formed between the storage tank 210 and the mother liquor tank 100. Several horizontal tubes 311 are connected at equal intervals along the axial direction on the outer circumferential surface of the infusion tube 310. The outer end of the horizontal tube 311 is closed. Several adjusting components 330 are respectively sleeved in the multiple horizontal tubes 311, and the horizontal tubes 311 provide installation positions for the adjusting components 330.

[0038] like Figure 4 and Figure 5As shown, the control assembly 320 further includes a float sleeve 321 and a float column 322. The bottom of the float sleeve 321 has a cavity 3211, and the top of the float sleeve 321 has a conical hole 3212. The bottom end of the float column 322 is connected to a sealing cone 3221, and the top end of the sealing cone 3221 has a connecting rod 3222. The top end of the connecting rod 3222 is fixedly connected to the bottom end of the float column 322. The sealing cone 3221 extends into the cavity 3211. Within 11, when the liquid level in the mother liquor tank 100 is lower than the set liquid level height, the sealing cone 3221 moves away from the cone hole 3212, causing the cone hole 3212 to open. At this time, the mother liquor in the storage tank 210 flows downward through the cone hole 3212 to the mother liquor tank 100, thus replenishing the mother liquor. When the liquid level in the mother liquor tank 100 reaches the set height, the float 322 floats up and drives the sealing cone 3221 to seal the cone hole 3212, stopping the replenishment of the mother liquor.

[0039] like Figures 4-6 As shown, in addition, a number of sealing lips 3213 are provided on the outer peripheral surface of the float sleeve 321. The sealing lips 3213 play a sealing role between the inner wall of the infusion tube 310 and the float sleeve 321, preventing the mother liquor from leaking from the gap between the float sleeve 321 and the infusion tube 310.

[0040] like Figure 4 and Figure 5 As shown, it is worth noting that the bottom end of the float 322 is fixed with several support plates 3223 in an annular shape at equal intervals. When the float 322 moves downward, the support plates 3223 support the bottom end of the float 322 and the top end of the float sleeve 321, preventing the bottom end of the float 322 from blocking the top end of the conical hole 3212, and ensuring that the conical hole 3212 can be opened normally when needed.

[0041] like Figure 3 and Figure 6As shown, it is worth noting that the adjusting assembly 330 includes a stop post 331 movable along the horizontal tube 311 and a pull rod 332 fixed to the tail end of the stop post 331. The pull rod 332 is T-shaped, with the T-shaped end of the pull rod 332 penetrating the end of the horizontal tube 311 and fixedly connected to the stop post 331. The T-shaped head end of the pull rod 332 is a gripping end. When the pull rod 332 is pushed towards the infusion tube 310, the pull rod 332 causes the stop post 331 to slide inward along the horizontal tube 311, causing the stop post 331 to... The end of the tube extends into the infusion tube 310. At this time, the end of the baffle 331 protrudes inward inside the infusion tube 310, so that the baffle 331 blocks the upward movement of the float sleeve 321. By adjusting the position of the baffle 331 on different horizontal tubes 311, the maximum upward movement height of the float sleeve 321 can be set. When the pull rod 332 is pulled outward, the pull rod 332 drives the baffle 331 to slide outward along the horizontal tube 311. At this time, the baffle 331 avoids the upward movement of the control component 320.

[0042] It should be added that the outer diameter of the float 322 is smaller than the outer diameter of the float sleeve 321, and the maximum distance that the baffle 331 extends into the infusion tube 310 is less than the radius difference between the float sleeve 321 and the float 322. This ensures that the baffle 331 can only block the float sleeve 321, preventing the baffle 331 from hitting the float 322 when it extends into the infusion tube 310, thus ensuring the normal operation of the device.

[0043] In addition, the delivery pump 220 involved in this utility model is existing conventional technology, and will not be described in detail here.

[0044] In this embodiment, the liquid level regulating device for high-purity gallium production operates as follows: First, according to production process requirements, the pull rod 332 pushes the baffle 331 inward along the horizontal tube 311 until the pull rod 332 touches the end of the horizontal tube 311, causing the baffle 331 to extend into the horizontal tube 311. At this time, the baffle 331 blocks the upward movement of the float sleeve 321, thus setting the maximum upward movement height of the float sleeve 321 and determining the target liquid level in the mother liquor tank 100. Then, when the mother liquor in the mother liquor tank 100 is consumed due to the reaction and the liquid level drops below the set height, the float sleeve 321 and the float 322 descend with the liquid level. At this time, the sealing cone 3221 moves downward away from the cone hole 3212, opening the cone hole 3212. The mother liquor in the storage tank 210 then flows through the cone hole 3222. 12 flows along the infusion pipe 310 to the mother liquor tank 100 to replenish the mother liquor; then, as the mother liquor is replenished, the liquid level in the mother liquor tank 100 gradually rises, and the float sleeve 321 and float column 322 rise with the liquid level. When the float sleeve 321 rises to contact the baffle column 331, it is blocked by the baffle column 331. At this time, the continued rise of the float column 322 will drive the sealing cone 3221 to move upward until it seals the cone hole 3212, stopping the replenishment of mother liquor; finally, when there is too much mother liquor in the mother liquor tank 100 and the liquid level is higher than the set height, the transfer pump 220 is started to transfer the excess mother liquor in the mother liquor tank 100 to the storage tank 210. When the liquid level drops to the set height, the transfer pump 220 is stopped. This cycle is repeated to realize the automatic adjustment and control of the liquid level in the mother liquor tank 100.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
