Description
Technical Field
[0001] This utility model relates to the field of seed nitrogen sealing technology, and in particular to a seed nitrogen sealing device. Background Technology
[0002] "Seed nitrogen sealing equipment" is a specialized device that uses a nitrogen atmosphere to seal and protect crystals during crystal production (especially crystal growth, seed preservation or processing). Its core function is to use the inert properties of nitrogen to create an environment that isolates the seed crystal (the "seed" of the crystal, the original crystal used to induce subsequent crystal growth) from oxygen, moisture or other impurities, so as to ensure the stability and activity of the seed crystal.
[0003] The inlet and outlet of existing seed nitrogen sealing equipment are mostly fixed small diameter and bolted, which results in a narrow operating space when picking up and putting down crystals. When dealing with blocky or large-particle seed crystals, operators have to operate manually or with the help of tools, which can easily cause seed contamination and breakage.
[0004] Therefore, given that the existing seed nitrogen sealing equipment has fixed small-diameter inlet and outlet that are secured with bolts, the space for crystal handling is narrow, and when encountering blocky or large-particle seed crystals, operators have to manually or with tools to operate them laboriously, which can easily contaminate the seed crystals or cause them to break upon impact, there is an urgent need to design a new type of seed nitrogen sealing equipment. Utility Model Content
[0005] To overcome the problems of existing seed nitrogen sealing equipment having fixed small-diameter inlet and outlet that are fastened with bolts, resulting in narrow space when picking up and placing crystals, operators have to manually or with tools to handle blocky or large seed crystals, which can easily contaminate the seed crystals or cause them to break upon impact.
[0006] The technical solution of this utility model is as follows: a seed crystal nitrogen sealing device, including a sealing chamber and three adapter ports opened on the top of the sealing chamber. A limiting groove is opened inside the sealing chamber corresponding to the position of the adapter port. A limiting block is movably connected inside the limiting groove. A storage chamber is connected to the top of the limiting block. Several hollow grooves are opened on the outer end of the storage chamber. A threaded column is threadedly connected to the upper side of the inside of the storage chamber. A rotating plate is connected to the top of the threaded column. A threaded sleeve is connected to the top of the rotating plate. A threaded rod is threadedly connected inside the threaded sleeve. A cover plate is connected to the top of the threaded rod. A handle is connected to the top of the cover plate. A sealing ring is connected to the bottom of the cover plate. When the seed crystal is placed inside the hollow groove, the rotating plate rotates to drive the threaded column to connect with the storage chamber. Then, the handle drives the threaded rod and threaded sleeve to insert into the adapter port, causing the limiting block at the bottom of the storage chamber to coincide with the limiting groove. Rotating the handle drives the cover plate to drive the sealing ring to fit into the sealing chamber.
[0007] Preferably, by setting up three independent storage compartments and corresponding adapter ports, different sizes of seed crystals can be stored separately. The hollow groove at the outer end of the storage compartment facilitates the flow of nitrogen to form a uniform nitrogen-sealed environment and allows for direct observation of the seed crystal state inside. When taking out the seed crystal, simply rotate the handle to drive the threaded rod out of the threaded sleeve, and the cover plate and storage compartment can be lifted upwards. The limiting block slides away along the limiting groove without disassembling the overall structure. When storing, after placing the seed crystal into the storage compartment, the rotating plate is used to tighten the threaded post to the storage compartment. Then, the limiting block is aligned with the limiting groove and placed into the adapter port. Rotating the handle drives the sealing ring at the bottom of the cover plate to fit and seal with the storage compartment. The whole process is convenient and avoids bumps and contamination when taking out the seed crystal, achieving efficient and convenient seed crystal storage and retrieval.
[0008] Preferably, the outer end of the storage compartment is connected to four support columns, and the bottom of the support columns is connected to a base.
[0009] Preferably, a nitrogen supply device is installed at the right end of the storage chamber, a pressure gauge is installed at the outer end of the nitrogen supply device, and a breather valve is connected to the rear top of the storage chamber.
[0010] Preferably, a timer is connected to the front end of the storage chamber, and the nitrogen supply equipment is connected to the storage chamber.
[0011] Preferably, a nitrogen supply device continuously supplies nitrogen to the storage chamber, and a pressure gauge monitors the current internal pressure of the storage chamber.
[0012] Preferably, a breather valve maintains the internal pressure of the storage chamber, and a timer is used to record the storage time.
[0013] Preferably, the sealing ring is movably connected to the storage chamber, and the storage chamber is matched with the adapter port.
[0014] The beneficial effects of this utility model are:
[0015] 1. By setting up three independent storage compartments and corresponding adapter ports, when retrieving seed crystals, there is no need to disassemble the overall structure. Simply rotate the handle to drive the threaded rod out of the threaded sleeve, and you can directly lift the cover plate and storage compartment upwards. The limiting block slides away along the limiting groove to complete the retrieval. The operation steps are simple and time-saving. When storing seed crystals, after placing the seed crystals into the storage compartment, align the limiting block with the limiting groove and place it into the adapter port. Then rotate the rotating plate to tighten the threaded rod with the storage compartment. Rotating the handle drives the sealing ring at the bottom of the cover plate to fit and seal with the storage compartment. The whole process is smooth and convenient, without complicated operations, which greatly improves the convenience of seed crystal retrieval and storage, allowing operators to easily complete the seed crystal storage and retrieval work.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-5This utility model provides an embodiment: a seed nitrogen sealing device, including a sealing chamber 1 and three adapter ports 21 on the top of the sealing chamber 1. A limiting groove 22 is formed inside the sealing chamber 1 corresponding to the positions of the adapter ports 21. A limiting block 23 is movably connected inside the limiting groove 22. A storage chamber 24 is connected to the top of the limiting block 23. Several hollow grooves 25 are formed at the outer end of the storage chamber 24. A threaded post 26 is threadedly connected to the upper side of the inside of the storage chamber 24. A rotating plate 27 is connected to the top of the threaded post 26. The top of the rotating plate 27 is connected to a threaded sleeve 28, and the inside of the threaded sleeve 28 is connected to a threaded rod 29. The top of the threaded rod 29 is connected to a cover plate 210, the top of the cover plate 210 is connected to a handle 211, and the bottom of the cover plate 210 is connected to a sealing ring 212. When the seed crystal is placed inside the hollow groove 25, the rotation of the rotating plate 27 drives the threaded column 26 to connect with the storage chamber 24. Then, the handle 211 drives the threaded rod 29 and the threaded sleeve 28 to insert into the fitting port 21, driving the bottom of the storage chamber 24... The limiting block 23 coincides with the limiting groove 22. Rotating the handle 211 drives the cover plate 210 to bring the sealing ring 212 into contact with the storage chamber 1. By setting three independent storage chambers 24 and corresponding adapter ports 21, different specifications of seed crystals can be stored separately. The hollow groove 25 at the outer end of the storage chamber 24 facilitates the flow of nitrogen to form a uniform nitrogen sealing environment and allows for direct observation of the internal seed crystal state. When taking out the seed crystal, simply rotate the handle 211 to drive the threaded rod 29 out of the threaded sleeve 28, and the cover plate 210 can be lifted upwards. The limiting block 23 slides away from the storage chamber 24 along the limiting groove 22 without disassembling the overall structure. When storing, after placing the seed crystal into the storage chamber 24, the threaded post 26 is fastened to the storage chamber 24 by rotating the rotating plate 27. Then, the limiting block 23 is aligned with the limiting groove 22 and placed into the adapter port 21. The rotating handle 211 drives the sealing ring 212 at the bottom of the cover plate 210 to fit and seal with the storage chamber 1. The whole process is convenient to operate, avoiding bumps and contamination when taking out the seed crystal, and realizing efficient and convenient storage and retrieval of the seed crystal.
[0024] Please see Figures 1-3In this embodiment, four support columns 31 are connected to the outer end of the storage chamber 1, and a base 32 is connected to the bottom of the support columns 31. A nitrogen supply device 33 is provided at the right end of the storage chamber 1, and a pressure gauge 34 is provided at the outer end of the nitrogen supply device 33. A breather valve 35 is connected to the rear top of the storage chamber 1, and a timer 36 is connected to the front end of the storage chamber 1. The nitrogen supply device 33 is connected to the storage chamber 1. The four support columns 31 and the base 32 cooperate with each other to provide stable support for the entire storage chamber 1, effectively preventing the equipment from tilting or shaking during use, and ensuring the stability of the equipment operation. The nitrogen supply device 33 can efficiently deliver nitrogen into the storage chamber 1. The pressure gauge 34 can monitor the pressure inside the chamber in real time, and the breather valve 35 can adjust the pressure inside the chamber in a timely manner, thereby protecting the stability of the nitrogen sealing environment. The timer 36 can accurately record the storage time of the seed crystals, making it convenient for operators to grasp the optimal usage period of the seed crystals.
[0025] Please see Figures 2-5 In this embodiment, the nitrogen supply device 33 continuously supplies nitrogen to the storage chamber 1, the pressure gauge 34 monitors the current internal pressure of the storage chamber 1, the breather valve 35 maintains the internal pressure of the storage chamber 1, the timer 36 records the storage time, the sealing ring 212 is movably connected to the storage chamber 1, and the storage chamber 24 is matched with the adapter port 21. The continuous nitrogen supply by the nitrogen supply device 33 ensures that the storage chamber 1 is always in an inert environment, effectively preventing the seeds from oxidizing and deteriorating. The pressure gauge 34 and the breather valve 35 work together to stabilize the pressure inside the chamber, avoiding both excessive pressure that could damage the equipment and excessively low pressure that could allow outside air to seep in. The presence of the timer 36 helps operators track the storage status of the seeds. The movable connection between the sealing ring 212 and the storage chamber 1 ensures good sealing and reduces nitrogen leakage. The matching of the storage chamber 24 and the adapter port 21 further improves the overall stability and safety of the equipment, ensuring that the seeds are in a reliable storage environment.
[0026] During operation, the seed crystal is first placed into the hollowed-out groove 25 of the storage chamber 24. The rotating plate 27 drives the threaded column 26 to connect and tighten with the storage chamber 24, ensuring the seed crystal is stably placed within the storage chamber 24. Then, by holding the handle 211, the threaded rod 29 and threaded sleeve 28 are aligned with the fitting port 21 at the top of the sealing chamber 1 and inserted, so that the limiting block 23 at the bottom of the storage chamber 24 precisely engages with the corresponding limiting groove 22 inside the sealing chamber 1, achieving initial positioning of the storage chamber 24. Next, rotating the handle 211 causes the threaded rod 29 to tighten within the threaded sleeve 28, forcing the sealing ring 212 at the bottom of the cover plate 210 to fit tightly against the top surface of the sealing chamber 1, completing the sealing operation. During operation, the nitrogen supply device 33 continuously supplies nitrogen gas into the sealing chamber 1, which passes through the hollowed-out groove 25 at the outer end of the storage chamber 24. Smooth flow between the storage chambers 24 creates a uniform and stable nitrogen-sealed environment. Operators can visually observe the seed crystal status inside through the perforated grooves 25. Four support columns 31 and the base 32 work together to provide stable support for the entire equipment. Pressure gauge 34 monitors the pressure inside the storage chamber 1 in real time, while the breather valve 35 automatically adjusts according to pressure changes to maintain stable pressure inside the chamber. Timer 36 records the seed crystal storage time simultaneously. When the seed crystal needs to be retrieved, the handle 211 is rotated in the reverse direction to rotate the threaded rod 29 out of the threaded sleeve 28, releasing the seal between the cover plate 210 and the storage chamber 1. Then, the handle 211 is lifted upwards, causing the cover plate 210 and the storage chamber 24 to rise together. At this time, the limit block 23 slides out along the limit groove 22, allowing the seed crystal inside the storage chamber 24 to be directly retrieved. The entire process does not require disassembling the overall structure of the equipment.
[0027] Through the above steps, with the three independent storage compartments 24 and corresponding adapter ports 21, when retrieving the seed crystal, it is not necessary to disassemble the entire structure. Simply rotate the handle 211 to unscrew the threaded rod 29 from the threaded sleeve 28, and you can directly lift the cover plate 210 and the storage compartment 24 upwards. The limiting block 23 slides out along the limiting groove 22, making retrieval easy. The steps are simple and time-saving. When storing the seed crystal, after placing the seed crystal into the storage compartment 24, align the limiting block 23 with the limiting groove 22 and insert it into the adapter port 21. Then rotate the rotating plate 27 to align the threaded post 26 with the storage compartment. 24. Tighten the handle 211 and finally rotate the handle 211 to make the sealing ring 212 at the bottom of the cover plate 210 fit and seal with the storage chamber 1. The whole process is smooth and convenient, without complicated operation, which greatly improves the convenience of seed crystal retrieval and storage. Operators can easily complete the storage and retrieval work. This solves the problem that the feed inlet and outlet of the existing seed crystal nitrogen sealing equipment are mostly fixed small diameter and bolted, which results in a narrow operating space when picking up and putting down crystals. When facing blocky or large-particle seed crystals, operators need to operate manually or with the help of tools, which can easily cause seed crystal contamination and collision breakage.
