Description

Technical Field

[0001] This utility model relates to the field of fluid machinery technology, and in particular to a pure water storage device. Background Technology

[0002] Substrate glass, carrier glass and other glass products are widely used in high-end manufacturing fields such as display panels and semiconductors. In their production process, pure water is required as a key carrier for cleaning, cooling and process media. The cleanliness requirements of pure water are extremely high, and the performance of pure water storage and circulation systems directly affects the cleanliness of the final product.

[0003] Existing pure water storage and treatment equipment exhibits significant technical shortcomings when adapting to these high-cleanliness production requirements: On the one hand, existing pure water storage and treatment equipment has a complex structure, with filters that are difficult to disassemble, requiring cumbersome replacement procedures and difficult cleaning, affecting the production environment and easily leading to product defects and a significant decrease in yield. On the other hand, due to the sealed structure of the tank, when the water level inside the tank drops, the air pressure inside the tank also decreases, creating a significant pressure difference with the outside. This causes the pure water outflow rate to gradually slow down, or even stagnate, affecting the continuity of production and product quality.

[0004] Therefore, there is an urgent need to develop a pure water storage device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve or at least alleviate some or all of the aforementioned problems. Therefore, the purpose of this invention is to provide a pure water storage device that simplifies filter replacement procedures, eliminates liquid stagnation, and ensures the stability of the production environment.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A pure water storage device includes a tank, a tank cover, a positive pressure device, a first primary filter, and a secondary filter. The tank is provided with a water outlet pipe at the bottom, and the tank cover is a sealing cap located at the top opening of the tank. The positive pressure device, the first primary filter, the secondary filter, and the tank cover are connected in series via connecting pipes. The first primary filter and the secondary filter are detachably connected to their respective connecting pipes.

[0008] In some optional embodiments, the first primary filter and the secondary filter are respectively threadedly connected to their respective connecting pipes.

[0009] In some optional embodiments, the pure water storage device further includes a second primary filter, which is connected in series between the positive pressure device and the first primary filter via the connecting pipe.

[0010] In some alternative embodiments, the second primary filter is threadedly connected to the connected conduit.

[0011] In some alternative embodiments, each of the connecting pipes is provided with the first seal at its connection end.

[0012] In some optional embodiments, the pure water storage device further includes a valve, a cleaning pipe, and a drain pipe. The valve is disposed on the connecting pipe between the secondary filter and the tank cover. The drain pipe is connected to the connecting pipe between the secondary filter and the valve. One end of the cleaning pipe is connected to the upstream of the secondary filter, and the other end can be connected to the water outlet pipe.

[0013] In some alternative embodiments, the pure water storage device further includes a negative pressure device, the output of which is connected to the drain pipe.

[0014] In some optional embodiments, the pure water storage device further includes a pure water delivery pipe connected to the tank cover for supplying pure water into the tank.

[0016] In some alternative embodiments, the positive pressure device is a controllable fan that can actively regulate the output air pressure.

[0017] The beneficial effects of this utility model are:

[0018] This utility model provides a pure water storage device, including a tank, a tank cover, a positive pressure device, a first primary filter, and a secondary filter.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] In this invention, the terms "comprising," "including," "having," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0027] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," "combined," "coupled," and "installed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can be a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For example, a direct connection refers to two parts or components being connected together without an intermediate component, while an indirect connection refers to two parts or components each being connected to at least one intermediate component, with the connection achieved through the intermediate component. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Furthermore, "connected" and "coupled" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0029] In this invention, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0030] In this invention, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can be performed by one part, one component, or a combination of multiple parts.

[0031] In this utility model, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationships shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, in the context, it should be understood that when an element is mentioned as being "upper" or "lower" of another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as "upper side," "lower side," "left side," "right side," "front side," and "rear side" not only represent positive orientation but can also be understood as lateral orientation. For example, "above," "on top of," "upper side of," and "above" of the first feature and the second feature include the first feature being directly above, to the upper left, to the upper right, to the upper front, and to the upper rear of the second feature, or simply indicating that the first feature is at a higher horizontal level than the second feature. The terms "below," "under," "below," and "below" for "first feature" and "second feature" include situations where the first feature is directly below, to the lower left, to the lower right, in front of, or behind the second feature, or simply indicate that the first feature is at a lower horizontal level than the second feature. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0032] like Figure 1 and Figure 2 As shown, this embodiment provides a pure water storage device, including a tank 1, a tank cover 2, a positive pressure device, a first primary filter 3, and a secondary filter 4. The tank 1 is provided with a water outlet pipe 5 at the bottom, and the tank cover 2 is sealed at the top opening of the tank 1. The positive pressure device, the first primary filter 3, the secondary filter 4, and the tank cover 2 are connected in series through a connecting pipe 6. The gas output by the positive pressure device can be filtered through the first primary filter 3 and the secondary filter 4 in sequence. Dust impurities in the gas are absorbed, and clean air is obtained to assist the elimination of the stagnant state of the liquid, thereby promoting the stable flow of pure water from the water outlet pipe 5, thus ensuring the stability of the production environment of downstream equipment.

[0033] The primary filter 3 and the secondary filter 4 are detachably connected to their respective connecting pipes 6, which simplifies the filter replacement process and allows for easy disassembly of the primary filter 3 or the secondary filter 4 for cleaning or replacement.

[0034] The primary filter 3 and the secondary filter 4 are connected to their respective connecting pipes 6 by threads. The filters can be easily installed and removed by screwing, improving operational convenience and ensuring stable connections that are easy to manufacture.

[0035] Furthermore, the pure water storage device also includes a second primary filter 7, which is connected in series between the positive pressure equipment and the first primary filter 3 via a connecting pipe 6. By adding the second primary filter 7, three-stage filtration is achieved, which helps to extend the service life of each filter and reduce the maintenance frequency.

[0036] Similarly, the second primary filter 7 is connected to its connected pipe 6 by a thread. Each filter can be easily installed and removed by screwing, improving operational convenience and ensuring a stable connection that is easy to manufacture.

[0037] Of course, in other embodiments, the filters and connecting pipes 6 may be connected by snap-fit ​​or flange, which can also achieve a detachable and sealed connection, and this is not limited here.

[0038] Furthermore, the pure water storage device also includes a first sealing element, and each connection end of the connecting pipe 6 is provided with a first sealing element to improve the sealing performance of the pure water storage device and prevent pure water contamination.

[0039] Optionally, the first seal may include, but is not limited to, an O-ring or a lip ring.

[0040] In some optional embodiments, the pure water storage device further includes a valve, a cleaning pipe 8, and a drain pipe 9. The valve is located on the connecting pipe 6 between the secondary filter 4 and the tank cover 2, and is used to control the opening and closing of the connecting pipe 6. The drain pipe 9 is connected to the connecting pipe 6 between the secondary filter 4 and the valve. One end of the cleaning pipe 8 is connected upstream of the secondary filter 4, and the other end can be connected to the outlet pipe 5. When the secondary filter 4 needs to be cleaned, the valve is closed, and the cleaning pipe 8 is connected to the outlet pipe 5. The pure water in the tank 1 can flow out from the outlet pipe 5, flow into the secondary filter 4 through the cleaning pipe 8 for cleaning, and the cleaned liquid is then discharged through the drain pipe 9.

[0041] In this embodiment, the cleaning pipe 8 is connected to the first primary filter 3. In other embodiments, the cleaning pipe 8 may also be connected to the connecting pipe 6 between the secondary filter 4 and the first primary filter 3, which is not limited here.

[0042] Furthermore, the pure water storage device also includes a negative pressure device, the output end of which is connected to the drain pipe 9. The negative pressure device can provide power to the pure water, driving the pure water to flow out from the outlet pipe 5 at the bottom of the tank 1, and then into the secondary filter 4 through the cleaning pipe 8 for cleaning.

[0043] In some optional embodiments, the pure water storage device further includes a pure water delivery pipe 10, which is connected to the tank cover 2 and is used to input pure water into the tank 1 to replenish the pure water reserve.

[0044] In some optional embodiments, the pure water storage device further includes a second seal disposed between the tank cover 2 and the tank body 1 to improve the sealing performance between the two and prevent pure water contamination.

[0045] Optionally, the second seal may include, but is not limited to, an O-ring or a lip ring.

[0046] In some optional embodiments, the first primary filter 3 and / or the second primary filter 7 are spherical mesh filters. As air passes through, the mesh creates a coalescing effect, adsorbing large particles onto the filter media, while the spherical shape increases the path of airflow, enhancing the filtration effect.

[0047] The secondary filter 4 can be selected according to the downstream equipment production process, including but not limited to columnar porous filters or cylindrical metal mesh filters, which are not limited here.

[0048] In some optional embodiments, the positive pressure device is a controllable fan that can actively regulate the output air pressure to ensure stable pressure inside the tank 1 and ensure that pure water flows out stably from the outlet pipe 5.

[0049] The specific structure of the controllable fan is existing technology and will not be described in detail here.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
