Description

Technical Field

[0001] The present invention relates to the field of vacuum technology, and in particular to a manually controlled adsorption material precision releasing device and a releasing method thereof. Background Art

[0002] Vacuum treatment is a common cavity treatment method in the industrial field. Any material that is in a vacuum for a long time will inevitably outgas, causing the vacuum degree of the vacuum cavity to decrease. Therefore, adsorbent materials must be placed in vacuum containers for long-term use to slow down the deterioration of the vacuum degree caused by the outgassing of the container. For a long time, how to release adsorbent materials under vacuum has been a difficult problem in the vacuum field. The traditional way of placing them is to quickly place the adsorbent materials before the vacuum cavity is closed, and then immediately evacuate the cavity. However, no matter how quickly, the adsorbent material will still experience a decrease in its adsorption effect to varying degrees due to contact with the air, and the process cannot be standardized due to different operations of operators.

[0003] Researchers in the vacuum field have proposed many methods, but the most ideal method must be the logic of "treating the adsorbent material in a vacuum, maintaining the vacuum environment after the treatment is completed, and then placing it into the target container when the target container is in a vacuum state."

[0004] Chinese patent application CN118770756A discloses a vacuum adsorption material delivery device and a release method thereof, wherein the delivery device comprises a vacuum cavity, a vacuum container is arranged in the vacuum cavity, and a cantilever connects the vacuum container and the vacuum cavity; the adsorption material is stored in the vacuum container, and a vacuum port is arranged at the upper end of the vacuum container, and vacuum is drawn through the vacuum port to keep the adsorption material in a vacuum environment in the vacuum container; the vacuum container is provided with a cover and a sealing ring, and the cover and the sealing ring are arranged at the lower end of the vacuum container as a release port for the adsorption material, and the vacuum cavity is vacuumed to change the internal and external pressure difference, which is used for opening and closing the vacuum container and delivering the adsorption material in the vacuum container. The problem to be solved by this technical document is similar to that of the present invention, but because the technical document adopts the pressure difference method, although it is theoretically feasible, it has little effect. This is because in the process of extracting the vacuum, the pressure change is linear, so before the vacuum degree reaches the target pressure of the technical document, the gradual decrease in the internal and external pressure difference causes the cover to loosen in advance, resulting in falling off. Therefore, in actual operation, the release timing of the solution proposed in this technical document will be greatly advanced, and the adsorption material using this release method will still experience significant degradation, which does not fundamentally solve the degradation problem of adsorbent release.

[0005] Chinese patent application US20040141850A1 discloses a vacuum adsorption material delivery device and a release method thereof, wherein the delivery device includes a vacuum cavity, and a vacuum container is arranged in the vacuum cavity. The vacuum container is divided into brittle materials, deformable materials and rigid materials. Among them, when using brittle materials, the patent uses the deformation of two plates to "crush" the vials made of brittle materials, and specifically notes that if the vials fail to break in time during the process, it is necessary to manually knock the plates to break them. Brittle materials will produce a large number of particles during the fracture and crushing process, and the vacuum container usually needs to be maintained every once in a while (i.e., re-vacuuming) after long-term use. The above particles will be sucked into the vacuum pump during the maintenance process. Usually, the vacuum pump needs to avoid inhaling solids. If solids are inhaled, the vacuum pump (especially the polymer pump) will cause blade damage due to the inhalation of solids, increase equipment depreciation and damage, and increase maintenance costs. When using deformable materials, the patent uses the change of internal and external pressure difference to expand the balloon, and the balloon is "punctured" after contacting the spikes, thereby releasing the contents. At present, the common deformable flexible deformable materials on the market will have a certain degree of degassing under vacuum. This kind of material will cause the vacuum to deteriorate continuously under vacuum, which will increase the maintenance cost and interval. When using rigid materials, the patent clearly states that the contents contained in it need to be fixed in the container. "Release" is a necessary means of this patent because, in the vacuum field, the larger the contact area between common adsorbent materials such as molecular sieves and the space, the stronger their adsorption capacity. Therefore, by scattering the adsorbent material in the container in a "falling off" manner, the performance of the adsorbent material can be ensured to the greatest extent. If the adsorbent material is made into the style in the comparative document, its contact area with the external space will be greatly reduced, and the adsorption capacity of the adsorbent material will be greatly reduced. From an engineering perspective, this formation is not a mature solution. At the same time, because in the case of rigid materials, the patent uses a film and a spring as a release mechanism, so there will be a situation in which the adsorbent material is released in advance in the Chinese patent application CN118770756A, so the adsorbent material will inevitably deteriorate. Summary of the invention

[0006] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a manually controlled adsorption material precise release device and a release method thereof. The adsorbent can be precisely released manually only by a pull rod without using any heating device.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0009] One end of the vacuum container is open, and a tie rod cover and a first sealing ring are arranged at the open end of the vacuum container.

[0012] Furthermore, the surface of one end of the pull rod of the pull rod cover is smooth.

[0014] Furthermore, before the rod cover slides, the rod cover, the first sealing ring, the vacuum port and the vacuum container form a sealing structure in which no medium exchange or flow occurs between the inner and outer spaces.

[0027] Furthermore, if the calculated tie rod cover mass is less than the actual tie rod cover mass, a tie rod buckle needs to be added.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The device of the present invention is designed with a manually controlled pull rod cover.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0043] Example 1

[0044] This embodiment intends to disclose a manually controlled adsorption material precise release device, the device is specifically as follows Figure 1As shown, it includes a vacuum port 1, a superconducting container 2, a cantilever 3, an adsorption material 4, a vacuum container 5, a first sealing ring 6, a tie rod cover 7 and a second sealing ring 8.

[0045] The superconducting container 2 is a vacuum space in a device with a vacuum structure, and the vacuum cavity refers to a vacuum space in a device with a vacuum structure commonly seen on the market and in engineering. The adsorbent material 4 is an adsorbent material placed in the vacuum structure of the device to mitigate the vacuum degradation caused by the degassing of the container.

[0046] The vacuum container 5 is inside the superconducting container 2 and connected to the superconducting container 2 via the cantilever 3. The cantilever 3 is usually also inside the superconducting container 2 and is a rigid body.

[0047] The vacuum port 1 is fixed on the vacuum container 5 , and the vacuum container 5 evacuates the internal environment through the vacuum port 1 .

[0048] One end of the vacuum container 5 is open, and the tie rod cover 7 and the first sealing ring 6 are arranged at the open end of the vacuum container 5 .

[0049] One end of the tie rod cover 7 seals the adsorbent material 4 in the vacuum container, and at the same time, one end of the tie rod of the tie rod cover 7 passes through the second sealing ring 8 on the superconducting container 2, and the tie rod is exposed outside the superconducting container 2. The operator can pull the tie rod cover 7 to slide the tie rod cover 7 outward to release the adsorbent material 4. The surface of one end of the tie rod of the tie rod cover 7 is smooth.

[0050] The rod cover 7, the second sealing ring 8 and the superconducting container 2 form a sealing structure in which no medium exchange or flow occurs between the inner and outer spaces. Similarly, before the rod cover 7 slides, the rod cover 7, the first sealing ring 6, the vacuum port 1 and the vacuum container 5 form a sealing structure in which no medium exchange or flow occurs between the inner and outer spaces.

[0051] The first sealing ring 6 and the second sealing ring 8 are rubber O-rings made of nitrile and fluororubber, with a vacuum sealing degree of 10 -5 Pa, if the superconducting container 2 requires a higher vacuum degree, a metal sealing ring is used instead.

[0052] The shapes of the vacuum container 5 and the tie rod cover 7 are changed according to the shape of the superconducting container 2. On the premise of ensuring the normal operation of the first sealing ring 6, they can be set to different sizes and shapes according to different engineering practice scenarios, including but not limited to special-shaped vacuum cavities with varying cross-sections.

[0053] The shape and size of the vacuum container 5 as a container of the adsorption material 4 have no effect on the release of the adsorption material 4. The shape of the vacuum container 5 should comply with the standard formula for the design of pressure vessels. The material of the vacuum container 5 includes stainless steel, epoxy resin or other materials with low degassing rate and high strength that will not break or damage due to vacuum negative pressure and can reduce the rate of vacuum degradation.

[0054] The standard formula for pressure vessel design is as follows:

[0055]

[0056] Where S is the vessel wall thickness, P is the design pressure, D is the diameter, and δ t is the allowable stress at the design temperature, φ is the welding coefficient, which is taken as 1.0 here, and C is the corrosion allowance.

[0057] The cantilever 3, as a supporting component of the vacuum container 5, only provides the supporting function of the vacuum container 5. Therefore, the connection position and connection method of the cantilever 3 and the vacuum container 5 or the superconducting container 2 can be changed according to the shape of the vacuum container 5 or the superconducting container 2, such as being placed on the side or directly connected to the superconducting container 2, but the position of the cantilever 3 cannot cover the opening of the vacuum container 5. For scenes that need to be frequently disassembled, the cantilever 3 can also be designed as a quick-connect structure such as a hook or a buckle.

[0058] In this embodiment, the vacuum container 5 is in a concave shape, and the pull rod cover 7 is in a flat plate shape, which can better release the adsorption material 4.

[0059] When placing the device into an integrated container, it needs to be placed during the processing, while a non-integrated container can be placed after the processing is completed. The placing process includes: passing the pull rod through the sealing hole, moving the vacuum container containing the adsorption material to the direction close to the sealing hole, and then connecting the cantilever. Since the connection method of the cantilever is not restricted, both integrated and non-integrated containers can be installed according to this process.

[0060] Example 2

[0061] Based on the above-mentioned embodiment 1, this embodiment designs another manually controlled adsorption material precise release device, and its structure is different from that of embodiment 1 in that the shapes of the vacuum container 5 and the tie rod cover 7 are different.

[0062] Generally, the larger the contact area between the molecular sieve and the space, the better the adsorption effect. On the contrary, if the adsorbent 4 is gathered together, the adsorption effect will be greatly reduced. However, some adsorbents 4, such as hydrogen absorbers, have small particles. If they are allowed to spread out, when the superconducting container 2 is evacuated during vacuum maintenance in the future, the hydrogen absorbers with small particles are likely to enter the vacuum pump used for evacuation along with the air flow, causing damage to the vacuum pump, reducing the life of the vacuum pump, and increasing maintenance costs.

[0063] like Figure 2 As shown, the vacuum container 5 of this embodiment is in the shape of a flat plate, and the tie rod cover 7 is in the shape of a concave letter. After the superconducting container 2 reaches a specified vacuum degree, the tie rod cover 7 is pulled downward to make the built-in adsorbent contact with the vacuum of the superconducting container 2. Although the adsorption effect is reduced to a certain extent, the concave-shaped container can effectively prevent the internal adsorbent from scattering.

[0064] The remaining parts of the adsorption material precise release device in this embodiment are consistent with those in Embodiment 1. The specific details can be understood by referring to the relevant descriptions and effects in Embodiment 1.

[0065] Example 3

[0066] Based on the above embodiment, this embodiment designs another manually controlled adsorption material precise release device, and its structure is different from that of the above embodiment in that the device of this embodiment further includes a superconducting vacuum port 9 and a superconducting vacuum port cover 10.

[0067] Figure 1 and Figure 2 In the embodiment, the rod cover 7 is provided with a vacuum interface on the superconducting container 2 and a second sealing ring 8 is used for vacuum sealing to realize the rod operation. Figure 3 As shown, this embodiment utilizes the existing superconducting vacuum port 9 on the superconducting container 2, i.e., the equipment with a vacuum structure, to arrange the vacuum container 5 and the tie rod cover 7. The superconducting vacuum port 9 is a port originally used for vacuuming the equipment with a vacuum structure, and the tie rod cover 7, the superconducting vacuum port 9, the superconducting vacuum port cover 10 and the superconducting container 2 form a sealed structure in which no medium exchange or flow occurs between the inner and outer spaces.

[0068] By using the existing superconducting vacuum outlet 9 to arrange the vacuum container 5 , it is possible to avoid adding a vacuum outlet to the superconducting container 2 .

[0069] When the device of this embodiment is used to accurately release the adsorbent material, the device with a vacuum structure needs to use a three-way pipe to extract air when the vacuum port is used for subsequent vacuum extraction, so as to prevent the pull rod of the pull rod cover 7 from affecting the vacuum extraction quality and efficiency. At the same time, this device is more suitable for containers such as terminals and liquid nitrogen tanks. As long as the adsorbent material is scattered at the bottom, a better adsorption effect can be achieved, and the influence of the deterioration of the adsorbent material can be reduced by placing it in large quantities.

[0070] The remaining parts of the device for accurately releasing adsorbent materials in this embodiment are consistent with those in the above embodiment, and the specific details can be understood by referring to the relevant descriptions and effects in the above embodiment.

[0071] Example 4

[0072] Based on the above embodiment, this embodiment designs another manually controlled adsorption material precise release device, and its structure is different from the above embodiment in that: Figure 4 As shown, the upper half of the cover portion of the pull rod cover 7 is in the shape of a convex character.

[0073] In this embodiment, the pull rod cover 7 of this shape is more conducive to the scattering of the adsorbent material.

[0074] The remaining parts of the device for accurately releasing adsorbent materials in this embodiment are consistent with those in the above embodiment, and the specific details can be understood by referring to the relevant descriptions and effects in the above embodiment.

[0075] Example 5

[0076] Based on the above embodiment, this embodiment designs another manually controlled adsorption material precise release device, and its structure is different from the above embodiment in that: Figure 5 As shown, the device also includes a pull rod buckle 11.

[0077] Since the shapes of the vacuum container 5 and the tie rod cover 7 will vary depending on the application scenario and the quality of the adsorption material 4 is also different, in order to ensure the sealing of the vacuum container 5 and the tie rod cover 7, it is necessary to use a vacuum container quantitative formula to calculate and determine whether an additional tie rod buckle is needed to fix the tie rod cover 7 and the vacuum container 5.

[0078] The quantitative formula of the vacuum container includes:

[0079]

[0080] Wherein, k1 is the mass of the adsorption material 4, k2 is the mass of the tie rod cover 7, μ is the friction coefficient, S is the cross-sectional area of ​​the cover end of the tie rod cover 7, p is the internal and external pressure difference, and g is the gravity constant.

[0081] If the mass k1 of the adsorbent material 4 calculated according to the formula is less than the actual mass of the adsorbent material 4, the rod buckle 11 is required to fix the rod of the rod cover 7 to the superconducting container 2. The fixing method is not limited, but it must be a detachable structure, such as a threaded and screw-on structure.

[0082] The remaining parts of the device for accurately releasing adsorbent materials in this embodiment are consistent with those in the above embodiment, and the specific details can be understood by referring to the relevant descriptions and effects in the above embodiment.

[0083] Example 6

[0084] Based on the above embodiment, this embodiment designs another manually controlled adsorption material precise release device, and its structure is different from the above embodiment in that: Figure 6 As shown, the shapes of the vacuum container 5 and the tie rod cover 7 are different, and the structure of the device is suitable for releasing the adsorbed material in the lateral direction.

[0085] The structures described in Examples 1-5 are generally for vertical release of adsorbed materials. When the structure of the superconducting container 2 is not suitable for installing a vertical vacuum container 5, a method can be used. Figure 6 The vacuum container 5 is installed on the side of the superconducting container 2 according to the side release structure described in the above.

[0086] In this embodiment, the inner walls of the vacuum container 5 and the tie rod cover 7 are both inclined surfaces, so as to prevent the adsorbed material from failing to be released and remaining in the vacuum container 5 and the tie rod cover 7 .

[0087] The remaining parts of the device for accurately releasing adsorbent materials in this embodiment are consistent with those in the above embodiment, and the specific details can be understood by referring to the relevant descriptions and effects in the above embodiment.

[0088] Example 7

[0089] Based on the above embodiment, this embodiment designs another manually controlled adsorption material precise release device, and its structure is different from the above embodiment in that: Figure 7 As shown, the superconducting container 2 and the tie rod cover 7 have different shapes, and the device further includes a cover 12, which is suitable for containers that have certain requirements on the flatness of the outer surface of the container.

[0090] The structures described in Examples 1-6 usually leave a portion of the pull rod on the container surface, which may have a certain impact on the daily use of the container. If you have certain requirements for the appearance of the container, or are sensitive to the protrusions on the outer surface, you can use Figure 7 The structure described in .

[0091] In this embodiment, the superconducting container 2 has a concave structure, the rod of the rod cover 7 is in the concave structure, and the rod of the rod cover 7 is relatively short, so that after the container successfully releases the adsorbent material, the rod of the rod cover 7 will not exceed the outer surface of the superconducting container 2. After the adsorbent material is successfully released, the cover 12 is used to cover the concave of the superconducting container 2, so that the surface of the superconducting container forms a relatively smooth plane. The connection method of the cover 12 and the superconducting container 2 is not limited, and can be connected by thread, welding or snap-on method.

[0092] The remaining parts of the device for accurately releasing adsorbent materials in this embodiment are consistent with those in the above embodiment, and the specific details can be understood by referring to the relevant descriptions and effects in the above embodiment.

[0093] Example 8

[0094] This embodiment intends to disclose the actual application method and process of releasing adsorbent materials by the manually controlled adsorbent material precision releasing device based on the above-mentioned embodiment.

[0095] like Figure 8 , showing the installation of a manually controlled adsorption material precision release device provided by the present invention in an actual liquid nitrogen storage tank container, Figure 8 In the figure, the vacuum space in the double vacuum wall of the liquid nitrogen storage tank container is the superconducting container 2. In the figure, part a shows the following Fig. 9 The left side shows the installation of the vertical vacuum container 5 using the existing vacuum interface and the Fig. 9 The right side shows the installation of the vertical vacuum container 5 using a dedicated interface, and part b shows how Fig.10 The vacuum container 5 is installed in the side direction as shown.

[0096] The specific process of the practical application method of the adsorption material release comprises:

[0097] Step S1, setting a precise release device for adsorbent material;

[0098] Step S1 specifically includes:

[0099] Step S101, according to the shape and size of the superconducting container 2, the shape, size, hardness and material of the vacuum container 5 are changed. The shape of the vacuum container 5 should comply with the standard formula for pressure vessel design;

[0100] Step S102, determining whether the pull rod buckle 11 is needed to fix the pull rod cover 7 and the vacuum container 5 by calculating through the vacuum container quantitative formula;

[0101] Step S103, placing the adsorption material 4 into the vacuum container 5 and sealing the vacuum container 5 using the tie rod cover 7 and the first sealing ring 6;

[0102] Step S104 , evacuate the vacuum container 5 to a vacuum state through the vacuum evacuation port 1 , and fix the vacuum container in the superconducting container 2 using the cantilever 3 .

[0103] Since the present invention needs to prevent the adsorbent material from contacting the internal space of the superconducting container 2 under normal pressure or low vacuum or medium vacuum environment, it is necessary to calculate the pressure difference between the inner and outer containers and the mass of the adsorbent. The mass of the adsorbent is mainly determined by the mass of the tie rod cover 7 and the internal and external pressure difference.

[0104] Step S2, evacuating the superconducting container 2 to a vacuum state;

[0105] Step S3 , pulling the rod cover 7 to release the adsorption material 4 in the vacuum container 5 .

[0106] If the above method is implemented in the form of a software functional unit and sold or used as an independent product, it can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, or the part that contributes to the prior art, or the part of the technical solution, can be embodied in the form of a software product. The computer software product is stored in a storage medium, including several instructions to enable a computer device, such as a personal computer, a server, or a network device, to perform all or part of the steps of the method described in each embodiment of the present invention. The aforementioned storage medium includes: U disk, mobile hard disk, read-only memory ROM, Read-Only Memory, random access memory RAM, Random Access Memory, disk or optical disk, and other media that can store program codes.

[0107] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
