Abstract
Description
Technical Field
[0001] This utility model relates to the field of zirconium metallurgical and chemical equipment technology, and more specifically, to a closed online sampling device for solid zirconium tetrachloride. Background Technology
[0002] Solid zirconium tetrachloride is an important inorganic chloride of zirconium. It is a white crystalline solid at room temperature with a pungent odor. It is extremely hygroscopic and will hydrolyze violently when it comes into contact with water, releasing hydrogen chloride and forming zirconium dioxide hydrate. It easily sublimates when heated under normal pressure. It is a core raw material for the preparation of metallic zirconium and zirconium-based compounds. It can also be used as an organic synthesis catalyst and is widely used in metallurgy, ceramics, chemical industry and other fields. It needs to be stored in a sealed and dry place.
[0003] Existing conventional sampling devices have insufficient sealing, allowing external moisture to easily seep in during operation, causing material hydrolysis and clumping, clogging sampling pipelines, and corroding the inner wall of the device. This not only damages the purity and representativeness of the sample but also threatens operational safety and accelerates equipment wear and tear. Utility Model Content
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.
[0005] Therefore: The first aspect of this utility model proposes a closed online sampling device for solid zirconium tetrachloride. The sampling device is used for a conveying pipeline for solid zirconium tetrachloride. The conveying pipeline includes a feed pipe and a connecting pipe. The sampling device includes a through pipe, a sampling component and an exhaust pipe.
[0006] One end of the connecting pipe is fixed to the feeding pipe; the through pipe is fixed through the connecting pipe, and the end of the through pipe near the feeding pipe extends into the interior of the feeding pipe; the material handling assembly includes an end chuck, a drive cylinder, a material handling rod, two sealing discs, and a discharge pipe. The end chuck is fixed to the end of the through pipe away from the feeding pipe; the cylinder body of the drive cylinder is fixed to the end chuck; the material handling rod is fixed to the piston rod of the drive cylinder; the two sealing discs are fixed at intervals to the outer wall of the material handling rod, and the two sealing discs are in contact with the inner wall of the through pipe; the discharge pipe is connected to the lower part of the through pipe; the exhaust pipe is connected to the upper part of the through pipe for discharging air and exhaust gas from inside the through pipe; wherein, when the drive cylinder drives the two sealing discs to move to the first position where the through pipe is near the feeding pipe, the two sealing discs and the part of the through pipe extending into the interior of the feeding pipe enclose a material handling chamber, and the opening of the material handling chamber faces the feeding end of the feeding pipe; when the drive cylinder drives the two sealing discs to move to the second position where the discharge pipe communicates with the through pipe, the space between the discharge pipe and the two sealing discs is connected.
[0007] Furthermore, the connecting pipe is inclined upward relative to the axis of the feed pipe to prevent solid zirconium tetrachloride from accumulating at the end of the through pipe extending into the feed pipe when sampling is not required.
[0008] Furthermore, the material handling rod is threadedly connected to the piston rod of the drive cylinder, and the piston rod of the drive cylinder slides through the end chuck.
[0009] Furthermore, the discharge pipe is connected to the through pipe, and a valve is installed at the lower end of the discharge pipe, while the exhaust pipe is connected to the through pipe.
[0010] Furthermore, the connecting pipe and the through pipe are fixed together by clamps, and the through pipe and the end chuck are fixed together by clamps.
[0011] Furthermore, the connecting pipe is welded and fixed to the feeding pipe, which is used to transport solid zirconium tetrachloride.
[0012] This invention proposes a closed online sampling device for solid zirconium tetrachloride. Solid zirconium tetrachloride is conveyed downwards from the feed end of the feed pipe. When sampling is required, the piston rod of the drive cylinder pushes the sampling rod along the axial direction of the through pipe towards the feed pipe. Two sealing discs fixed at intervals on the outer wall of the sampling rod move synchronously with the sampling rod until the two sealing discs move to the first position near the feed pipe end of the through pipe. At this point, the two sealing discs and the portion of the through pipe extending into the feed pipe together form a sampling chamber, with the opening of the sampling chamber facing the feed end of the feed pipe. The solid zirconium tetrachloride material falling from the feed pipe enters the sampling chamber under gravity, completing the sampling. After sampling, the drive cylinder reverses its action, and its piston rod drives the sampling rod to retract along the axial direction of the through pipe away from the feed pipe. The sealing disc retracts synchronously with the feeding rod, carrying the solid zirconium tetrachloride material in the feeding chamber into the through-tube until the two sealing discs move to the second position where the discharge pipe connects with the through-tube. At this point, the space between the discharge pipe and the two sealing discs is connected, and the solid zirconium tetrachloride material in the feeding chamber is discharged and collected through the discharge pipe under the action of gravity, thus completing one closed online sampling process. During the sampling process, the exhaust pipe is used to discharge the air and exhaust gas inside the through-tube, ensuring that the sampling process is carried out in a closed environment and preventing zirconium tetrachloride leakage or reaction with the outside air. When sampling is not required, the connecting pipe is inclined upward relative to the axis of the discharge pipe to prevent solid zirconium tetrachloride from accumulating at the end of the through-tube extending into the discharge pipe, avoiding long-term accumulation of material that may affect the sampling accuracy or cause pipeline blockage.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0018] Please see Figures 1 to 4 A closed online sampling device for solid zirconium tetrachloride is provided. The sampling device is used for the conveying pipeline of solid zirconium tetrachloride. The conveying pipeline includes a feed pipe 100 and a connecting pipe 200. The sampling device includes a through pipe 300, a sampling component 400 and an exhaust pipe 500.
[0019] One end of the connecting pipe 200 is fixed to the feeding pipe 100; the through pipe 300 is fixedly inserted through the connecting pipe 200, and the end of the through pipe 300 near the feeding pipe 100 extends into the interior of the feeding pipe 100; the material handling assembly 400 includes an end chuck 410, a drive cylinder 420, a material handling rod 430, two sealing discs 440, and a discharge pipe 450. The end chuck 410 is fixed to the end of the through pipe 300 away from the feeding pipe 100; the cylinder body of the drive cylinder 420 is fixed to the end chuck 410; the material handling rod 430 is fixed to the piston rod of the drive cylinder 420; the two sealing discs 440 are fixed at intervals to the outer wall of the material handling rod 430, and the two sealing discs 440 are fixed to the inner wall of the through pipe 300. The wall is fitted together, and the discharge pipe 450 is connected to the lower part of the through pipe 300; the exhaust pipe 500 is connected to the upper part of the through pipe 300 to discharge the air and exhaust gas inside the through pipe 300; wherein, when the drive cylinder 420 drives the two sealing discs 440 to move to the first position of the through pipe 300 near the end of the discharge pipe 100, the two sealing discs 440 and the part of the through pipe 300 extending into the discharge pipe 100 enclose a material taking chamber, and the opening of the material taking chamber faces the feeding end of the discharge pipe 100; when the drive cylinder 420 drives the two sealing discs 440 to move to the second position where the discharge pipe 450 and the through pipe 300 are connected, the space between the discharge pipe 450 and the two sealing discs 440 is connected.
[0020] In this embodiment: One end of the connecting pipe 200 is fixed to the feeding pipe 100; the connecting pipe 200 is a transitional connecting component between the feeding pipe 100 and the through pipe 300, and one end of it is fixed to the side wall of the feeding pipe 100, so that the through pipe 300 and the material taking component 400 can be stably installed on the feeding pipe 100 through the connecting pipe 200.
[0021] The through-tube 300 is fixedly inserted through the connecting tube 200, and the end of the through-tube 300 near the discharge tube 100 extends into the interior of the discharge tube 100; the through-tube 300 is inserted through the connecting tube 200 and extends into the interior of the discharge tube 100, so that the material taking chamber can directly extend into the material flow channel of the discharge tube 100 to take material, ensuring that the sample is directly obtained from the main material flow channel during the material taking process.
[0022] The material handling assembly 400 includes an end chuck 410, a drive cylinder 420, a material handling rod 430, two sealing discs 440, and a discharge pipe 450. The end chuck 410 is fixed to the end of the through pipe 300 away from the discharge pipe 100. The cylinder body of the drive cylinder 420 is fixed to the end chuck 410. The material handling rod 430 is fixed to the piston rod of the drive cylinder 420. The end chuck 410 serves as both a mounting base for the drive cylinder 420 and a seal for the outer port of the through pipe 300, preventing outside air from entering the through pipe 300 and ensuring the airtightness of the sampling equipment. It also provides end support and positioning reference for the reciprocating motion of the material handling rod 430. All parts of the material handling assembly 400 that come into contact with the medium are made of Hastelloy, 316L stainless steel, or silicon carbide, with no titanium materials involved.
[0023] Two sealing discs 440 are fixed at intervals to the outer wall of the picking rod 430, and the two sealing discs 440 are in contact with the inner wall of the through pipe 300. The discharge pipe 450 is connected to the lower part of the through pipe 300. The two sealing discs 440 are fixed at intervals along the axial direction of the picking rod 430 to the outer wall of the picking rod 430. The axial distance between the two sealing discs forms a material-containing space for accommodating solid zirconium tetrachloride material. The outer diameter of the sealing discs 440 is adapted to the inner diameter of the through pipe 300, so that the outer peripheral surfaces of the two sealing discs 440 are in sliding and sealing contact with the inner wall of the through pipe 300. During the reciprocating motion of the picking rod 430, the contact path between the outside air and the material in the pipe is blocked. The inner cavity of the discharge pipe 450 is connected to the inner cavity of the through pipe 300, and is used to discharge and collect the sampled solid zirconium tetrachloride material from the through pipe 300.
[0024] The exhaust pipe 500 is connected above the through pipe 300 to exhaust the air and exhaust gas inside the through pipe 300. Before sampling, the inside of the through pipe 300 can be evacuated multiple times through the exhaust pipe 500 and replaced with high-purity argon gas to completely remove the air and water vapor in the cavity. This prevents zirconium tetrachloride from hydrolyzing with moisture in the air to generate hydrogen chloride and zirconium oxide impurities, ensuring an inert atmosphere for the sampling environment and avoiding safety hazards caused by the leakage of harmful gases during the sampling process.
[0025] When the drive cylinder 420 drives the two sealing discs 440 to move to the first position near the end of the through pipe 300 close to the feed pipe 100, the two sealing discs 440 and the portion of the through pipe 300 extending into the feed pipe 100 enclose a material-taking chamber, the opening of which faces the feed end of the feed pipe 100. The first position is the material-taking station. When the drive cylinder 420 drives the two sealing discs 440 to move to the first position near the end of the through pipe 300 close to the feed pipe 100, the sealing disc on the side close to the feed pipe 100 is positioned within the through pipe. The port area 300 extends into the inside of the feed pipe 100. The sealing disc on the side away from the feed pipe 100 is located inside the body of the through pipe 300. The two sealing discs 440 and the part of the through pipe 300 extending into the feed pipe 100 together form a material picking chamber with one end open. The opening of the material picking chamber faces the feed end of the feed pipe 100, that is, the direction in which the material in the feed pipe 100 falls. This allows the solid zirconium tetrachloride material conveyed downward in the feed pipe 100 to fall directly into the material picking chamber under the action of gravity, thus completing the online material picking action.
[0026] When the driving cylinder 420 drives the two sealing discs 440 to the second position where the discharge pipe 450 connects with the through pipe 300, the space between the discharge pipe 450 and the two sealing discs 440 is connected. The second position is the unloading station of the equipment. When the driving cylinder 420 drives the two sealing discs 440 to the second position where the discharge pipe 450 connects with the through pipe 300, the two sealing discs 440 are respectively located on both sides of the discharge pipe 450 connection port, so that the material holding space between the discharge pipe 450 and the two sealing discs 440 is directly opposite and connected. At this time, the solid zirconium tetrachloride material carried in the sampling chamber can be discharged downward through the discharge pipe 450 under the action of gravity, completing the sample collection.
[0027] Please see Figure 2 In some embodiments of this utility model, the connecting pipe 200 is inclined upward relative to the axis of the feeding pipe 100 to prevent solid zirconium tetrachloride from accumulating at one end of the through pipe 300 extending into the feeding pipe 100 when sampling is not required.
[0028] In this embodiment: The connecting pipe 200 is inclined upward relative to the axis of the feeding pipe 100 to prevent solid zirconium tetrachloride from accumulating at the end of the through pipe 300 extending into the feeding pipe 100 when sampling is not required. In the non-sampling state, solid zirconium tetrachloride particles falling into the feeding pipe 100 are unlikely to accumulate and stay at the inclined pipe opening under the action of gravity, and will slide back into the main channel of the feeding pipe 100 along the inclined surface.
[0029] Please see Figure 3 In some embodiments of this utility model, the material taking rod 430 is threadedly connected to the piston rod of the drive cylinder 420, and the piston rod of the drive cylinder 420 slides through the end chuck 410.
[0030] In this embodiment: The picking rod 430 is threadedly connected to the piston rod of the drive cylinder 420, and the piston rod of the drive cylinder 420 slides through the end chuck 410. The picking rod 430 and the piston rod of the drive cylinder 420 adopt a threaded connection structure. The end of the picking rod 430 near the drive cylinder 420 is provided with a matching threaded section, which is screwed and fixed to the thread at the end of the piston rod, which facilitates the disassembly and maintenance of the picking rod 430 and the sealing plate 440, the adjustment of axial position accuracy, and the replacement of worn parts.
[0031] Please see Figure 2 In some embodiments of this utility model, the discharge pipe 450 is connected to the through pipe 300, and a valve is provided at the lower end of the discharge pipe 450, and the exhaust pipe 500 is connected to the through pipe 300.
[0032] In this embodiment: The discharge pipe 450 is connected to the through pipe 300, and a valve is provided at the lower end of the discharge pipe 450. The exhaust pipe 500 is connected to the through pipe 300. The valve at the lower end of the discharge pipe 450 can be kept closed during the vacuuming and argon replacement stages before sampling, so that a closed space is formed inside the through pipe 300, which facilitates multiple vacuuming and high-purity argon replacement operations through the exhaust pipe 500 to discharge air and water vapor from the cavity.
[0033] Please see Figure 1 In some embodiments of this utility model, the connecting pipe 200 and the through pipe 300 are fixed by clamps, and the through pipe 300 and the end chuck 410 are fixed by clamps.
[0034] In this embodiment: The connecting pipe 200 and the through pipe 300 are fixed together by clamps, and the through pipe 300 and the end chuck 410 are fixed together by clamps. The clamp connection method not only ensures the sealing and connection strength of each connection part, but also facilitates the installation, maintenance and replacement of parts of the equipment.
[0035] Please see Figure 1 In some embodiments of this utility model, the connecting pipe 200 is welded and fixed to the feeding pipe 100, and the feeding pipe 100 is used to transport solid zirconium tetrachloride.
[0036] In this embodiment: The connecting pipe 200 is welded and fixed to the feeding pipe 100. The feeding pipe 100 is used to transport solid zirconium tetrachloride. As the main conveying channel for solid zirconium tetrachloride, the feeding pipe 100 provides a continuous material source for online sampling, enabling the sampling equipment to obtain representative samples in real time without interrupting the production process.
