Description

Technical Field

[0001] This invention relates to the field of zirconium-hafnium extraction technology, and more particularly to an online degassing device for the zirconium-hafnium extraction process. Background Technology

[0002] The extraction and separation of zirconium and hafnium is a critical and challenging technology in high-end fields such as nuclear industry and aerospace. Due to their extremely similar chemical properties, the separation process is quite challenging. In the zirconium-hafnium extraction process, online degassing is carried out throughout the entire extraction process.

[0003] In existing online degassing devices, liquid is introduced into the degassing tank and flows onto the trays. Because the liquid flows in a constant direction, the liquid distribution on the trays is uneven, and the escaping gas is blocked by the accumulated liquid, reducing the degassing effect. Summary of the Invention

[0004] This invention discloses an online degassing device for the zirconium-hafnium extraction process, aiming to solve the technical problem that in existing online degassing devices, when liquid is introduced into the degassing tank and flows onto the tray, the liquid distribution on the tray is uneven due to the constant flow direction of the liquid. This causes the escaped gas to be blocked by the accumulated liquid, reducing the degassing effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An online degassing device for zirconium-hafnium extraction includes a tank body. The tank body has an internal multi-dispersion liquid distribution mechanism, which includes a ring guide rail fixedly connected to the inner wall of the tank body. An annular slide rod is slidably connected inside the ring guide rail, and a mounting plate is fixedly connected to the inner ring of the annular slide rod. The mounting plate has annular mounting holes, and a tray is fixedly connected inside each mounting hole. An installation block is fixedly connected to the inner wall of the tank body above the ring guide rail, and a liquid guide hopper is fixedly connected to one side of the installation block. The liquid guide hopper is located directly above one of the trays. A flow hole is opened at the bottom of the liquid guide hopper, and a connecting pipe is connected inside the flow hole via a bearing. A flow guide frame is fixedly connected to the bottom of the connecting pipe, and liquid distribution holes are opened on the downward-facing inclined surface of the flow guide frame. A retention rack is fixedly connected at equal intervals at the bottom of the mounting plate below each tray, and each retention rack has a liquid passage hole.

[0006] By incorporating multiple dispersing liquid distribution mechanisms, during liquid introduction, the liquid flows through the liquid guide pipe into the liquid guide hopper. The third drive motor is activated, and its active rotating gear drives the driven rotating gear to rotate, thereby rotating the guide frame below the connecting pipe. This distributes the liquid in the liquid guide hopper evenly onto the trays through the distribution holes below the guide frame. Once the liquid distribution on a single tray is complete, the second drive motor is activated, driving the mounting plate to rotate and position the new tray below the guide frame. This ensures even liquid distribution across all trays, guaranteeing that any escaping gas can be separated from the liquid, preventing liquid accumulation from obstructing gas flow, and thus improving the degassing effect.

[0007] In a preferred embodiment, a motor frame three is fixedly connected to the arc surface of the liquid guide hopper, and a drive motor three is fixedly connected to the motor frame three. The output shaft of the drive motor three is fixedly connected to a drive shaft through a coupling. A drive gear is fixedly connected to the outer side wall of the drive shaft, and a driven gear is fixedly connected to the outer side wall of the connecting pipe. The drive gear and the driven gear mesh with each other.

[0008] In a preferred embodiment, a motor frame two is fixedly connected to the inner wall of the tank body below the ring guide rail, and a drive motor two is fixedly connected to the motor frame two. The output shaft of the drive motor two is fixedly connected to a drive shaft through a coupling. The top of the drive shaft is fixedly connected to the bottom of the mounting plate, and a flow guide is fixedly connected to the outer wall of the drive shaft above the drive motor two.

[0009] In a preferred embodiment, the top of the tank has a fixing hole, and a liquid guide pipe is fixedly connected inside the fixing hole. The outer wall of the liquid guide pipe is connected to an inlet valve through a flange, and the bottom end of the liquid guide pipe is located directly above the liquid guide hopper.

[0010] In a preferred embodiment, a pump frame is fixedly connected to the top of the tank at its center point, and a vacuum pump is fixedly connected to the pump frame. The vacuum pump's vacuuming end is connected to the inside of the tank through a pipe.

[0011] In a preferred embodiment, the air guide end of the vacuum pump is fixedly connected to an air guide pipe, and the outer wall of the tank is fixedly connected to a sleeve, through which the air guide pipe passes.

[0012] In a preferred embodiment, a grounding bracket is fixedly connected to the outer wall of the tank, and a drain hole is opened at the bottom of the tank. A drain pipe is fixedly connected inside the drain hole, and a drain valve is connected to the outer wall of the drain pipe through a flange.

[0013] In a preferred embodiment, the inner top wall of the tank located below the vacuum pump is provided with a filtration mechanism, and the filtration mechanism includes a sealing cover, which is fixedly connected to the inner top wall of the tank located below the vacuum pump.

[0014] In a preferred embodiment, a filter cartridge is fixedly connected to the inner wall of the sealing cover, and the filter cartridge separates the sealing cover from the tank body.

[0015] By incorporating a filtration mechanism, as the vacuum pump pumps the gas from inside the tank, the gas passes through the filter cartridge, separating the liquid carried in the gas and preventing excessive liquid loss. Simultaneously, the drive motor is periodically activated, which rotates the brush plate via a rotating ring. The brush bristles on the brush plate brush off the liquid adhering to the filter cartridge, preventing liquid accumulation that could obstruct gas flow.

[0016] In a preferred embodiment, a motor frame is fixedly connected to the outer wall of the sealing cover, and a drive motor is fixedly connected to the motor frame. The output shaft of the drive motor is fixedly connected to a rotating shaft via a coupling. A rotating ring is fixedly connected to the outer wall of the rotating shaft, and a brush plate is fixedly connected to the outer wall of the rotating ring. The brush plate has bristles on its arc surface facing the inside of the filter cartridge, and the bristles are in contact with the inner wall of the filter cartridge.

[0017] The online degassing device for the zirconium-hafnium extraction process provided by this invention has the following technical effects: When liquid is introduced, the liquid flows into the liquid hopper through the liquid guide pipe. The drive motor three is started, and the drive motor three drives the driven gear to rotate through the active rotating gear, thereby driving the guide frame below the connecting pipe to rotate. The liquid on the liquid guide hopper is evenly distributed on the tray through the liquid distribution holes below the guide frame. After the liquid on a single tray is arranged, the drive motor two is started. The drive motor two drives the mounting plate to rotate, rotating the new tray below the guide frame, thereby evenly completing the liquid distribution operation of each tray. This ensures that the escaped gas can be separated from the liquid and avoids the accumulation of liquid causing gas obstruction. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] The online degassing device for zirconium-hafnium extraction disclosed in this invention is mainly applied to scenarios where existing online degassing devices, when using them, introduce liquid into the degassing tank and the liquid flows onto the trays, the liquid distribution on the trays becomes uneven due to the constant flow direction of the liquid, and the escaping gas is blocked by the accumulated liquid, thus reducing the degassing effect.

[0028] Reference Figures 1-7An online degassing device for zirconium-hafnium extraction includes a tank body 1. The tank body 1 has a multi-stage dispersion and distribution mechanism 11 inside, which includes an annular guide rail 1101 fixedly connected to the inner wall of the tank body 1. An annular slide rod 1112 is slidably connected inside the annular guide rail 1101, and a mounting plate 1102 is fixedly connected to the inner ring of the annular slide rod 1112. The mounting plate 1102 has annular mounting holes, and a tray 1103 is fixedly connected inside each mounting hole. A mounting block 1 is fixedly connected to the inner wall of the tank body 1 above the annular guide rail 1101. 106, and a liquid guide hopper 1105 is fixedly connected to one side of the mounting block 1106. The liquid guide hopper 1105 is located directly above one of the trays 1103. A flow hole is opened at the bottom of the liquid guide hopper 1105. A connecting pipe 1108 is connected to the inside of the flow hole through a bearing. A flow guide frame 1104 is fixedly connected to the bottom of the connecting pipe 1108. A liquid distribution hole 1118 is opened on the downward-facing inclined surface of the flow guide frame 1104. A retention rack 1116 is fixedly connected at equal intervals at the bottom of the mounting plate 1102 below each tray 1103. Each retention rack 1116 has a liquid passage hole 1117.

[0029] In specific application scenarios, when introducing liquid, the liquid flows through the liquid guide pipe 3 into the liquid guide hopper 1105. The drive motor 3 1109 is started, and the drive motor 3 1109 drives the driven gear 1114 to rotate through the active rotating gear 1113, thereby driving the flow guide frame 1104 below the connecting pipe 1108 to rotate. The liquid on the liquid guide hopper 1105 is evenly distributed on the tray 1103 through the liquid distribution hole 1118 below the flow guide frame 1104. After the liquid on a single tray 1103 is arranged, the drive motor 2 1111 is started. The drive motor 2 1111 drives the mounting plate 1102 to rotate, rotating the new tray 1103 to below the flow guide frame 1104, thereby evenly completing the liquid distribution operation of each tray 1103, ensuring that the escaped gas can be separated from the liquid, avoiding the accumulation of liquid that would obstruct the gas, and thus improving the degassing effect.

[0030] It should be noted that after the liquid passes through the tray 1103, it falls onto each retention rack 1116. The retention rack 1116 briefly retains the liquid falling from the tray 1103, thereby extending its degassing time and improving the degassing effect.

[0035] Reference Figure 1 In a preferred embodiment, the air guide end of the vacuum pump 5 is fixedly connected to an air guide pipe 6, and the outer wall of the tank 1 is fixedly connected to a sleeve 7, through which the air guide pipe 6 passes.

[0036] Reference Figure 1 and Figure 2 In a preferred embodiment, a grounding bracket 8 is fixedly connected to the outer wall of the tank body 1, and a drain hole is opened at the bottom of the tank body 1. A drain pipe 12 is fixedly connected inside the drain hole, and a drain valve 9 is connected to the outer wall of the drain pipe 12 through a flange.

[0037] Reference Figure 1 , Figure 2 and Figure 7In a preferred embodiment, a filter mechanism 10 is provided on the top inner wall of the tank 1 located below the vacuum pump 5, and the filter mechanism 10 includes a sealing cover 1001, which is fixedly connected to the top inner wall of the tank 1 located below the vacuum pump 5.

[0038] Specifically, during the process of vacuum pump 5 pumping the gas out of tank 1, the gas passes through filter cartridge 1008 and the liquid carried in the gas is separated by filter cartridge 1008 to avoid excessive liquid loss. At the same time, drive motor 1005 is started periodically. Drive motor 1005 drives brush plate 1003 to rotate through rotating ring 1007. The brush bristles 1002 on brush plate 1003 brush off the liquid attached to filter cartridge 1008 to avoid the accumulation of liquid and obstruction of gas passage.

[0039] Reference Figure 7 In a preferred embodiment, a filter cartridge 1008 is fixedly connected to the inner wall of the sealing cover 1001, and the filter cartridge 1008 separates the sealing cover 1001 from the tank body 1. A motor frame 1004 is fixedly connected to the outer wall of the sealing cover 1001, and a drive motor 1005 is fixedly connected to the motor frame 1004.

[0040] Working principle: During use, liquid is introduced into the tank 1 through the liquid guide pipe 3. The liquid flows into the liquid guide hopper 1105 through the liquid guide pipe 3. The drive motor 3 1109 is started. The drive motor 3 1109 drives the driven gear 1114 to rotate through the active rotating gear 1113, thereby driving the guide frame 1104 below the connecting pipe 1108 to rotate. The liquid on the liquid guide hopper 1105 is evenly distributed on the tray 1103 through the liquid distribution holes 1118 below the guide frame 1104. After the liquid on a single tray 1103 is arranged, the drive motor 2 1111 is started. The drive motor 2 1111 drives the mounting plate 1102 to rotate, rotating the new tray 1103 to below the guide frame 1104. This operation continues until the online degassing of the liquid is completed. After the liquid passes through the tray 1103, it falls onto the various retention racks 1116. The retention racks 1116 briefly retain the liquid falling from the tray 1103, thereby extending its degassing time. During the degassing process, the vacuum pump 5 is started to extract the escaping gas. During the extraction process, the gas passes through the filter cartridge 1008, and the filter cartridge 1008 separates the liquid carried in the gas to avoid excessive liquid loss. At the same time, the drive motor 1005 is started periodically. The drive motor 1005 drives the brush plate 1003 to rotate through the rotating ring 1007. The brush bristles 1002 on the brush plate 1003 brush off the liquid adhering to the filter cartridge 1008. The extracted gas is discharged through the gas guide pipe 6 and collected, and the operation ends.
