Description

Large capacity capsule filter

[0001] The present invention relates to a large-capacity capsule filter, and more specifically, to a large-capacity capsule filter that receives an influent, removes impurities, and discharges the same.

[0002] In general, filters are used to filter out impurities or various pollutants harmful to the human body contained in liquid or gaseous fluids, and are used in various fields for industrial or household purposes.

[0003] However, as the filter industry becomes more specialized and sophisticated, the design of capsule filters that combine economy and efficiency is becoming increasingly important. Recently developed and commercially available filters are manufactured in capsule form and installed within a housing with a standardized design. This increases filtration capacity while minimizing installation space, making the development of economical and space-saving capsule filters a top priority.

[0004] However, as can be seen in the prior art, domestic patent registration No. 10-1558204, the conventional capsule filter is designed in such a way that it has an outlet in the center, a filtering part surrounding the outlet, and an inlet part arranged on the outside of the filtering part, so there was a limitation that the cross-sectional area of ​​the capsule filter, i.e. the installation area, inevitably had to be large.

[0005] In addition, due to the structural design of the capsule filter, the inlet and outlet of the filter did not fit with standard pipes, making it difficult to process large amounts of inflow liquid.

[0006] Capsule filters according to conventional technology structurally require a cross-sectional area of ​​a certain size or larger, and thus the housing must also be large, which is inefficient in terms of economic aspects and in terms of handling inflow liquid.

[0007] Therefore, the purpose of the present invention is to solve the above-mentioned problems and to provide a large-capacity capsule filter that can double the filtration flow rate by relatively increasing the filtration area while minimizing the installation area.

[0008] In order to solve the above problem, the present invention provides a capsule filter including a case part having a space provided therein to accommodate a filter part; and an upper cap covering an upper surface of the case part, wherein the filter part removes impurities contained in an inflow liquid, and the upper cap has an inlet for introducing the inflow liquid, an outlet for discharging a filtered liquid from which impurities have been removed, and a check hole formed therein.

[0009] According to one embodiment, the inlet and outlet are characterized in that they are formed in a left-right symmetrical structure based on the center portion of the upper cap.

[0010] According to another embodiment, the inlet is characterized in that it is opened or closed by a first check valve, and the outlet is characterized in that it is opened or closed by a second check valve.

[0011] According to another embodiment, the check hole is characterized in that it is formed to prevent incorrect installation when a worker installs the capsule filter into the housing.

[0012] The large-capacity capsule filter according to the present invention can minimize the installation area, increase the filtration area, and enable a worker to install it without error when installing it in a housing.

[0013] In addition, the effects of the present invention are not limited to those mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description below.

[0018] This application claims the benefit of priority from Korean Patent Application No. 10-2024-0102832, dated August 2, 2024, the entire contents of which are incorporated herein by reference.

[0019] The description of the present invention is merely an example for structural and functional explanation. Therefore, the scope of the present invention should not be construed as limited by the embodiments described herein. In other words, since the embodiments are capable of various modifications and may take various forms, the scope of the present invention should be understood to include equivalents that can realize the technical idea.

[0020] In addition, the purpose or effect presented in the present invention does not mean that a specific embodiment must include all of them or only include such effects, and therefore, the scope of the present invention should not be understood as being limited thereby.

[0021] In describing components of the present invention, when it is described that a component is “connected,” “coupled,” or “connected” to another component, it should be understood that the component may be directly connected or connected to the other component, but another component may also be “connected,” “coupled,” or “connected” between each component.

[0022] Additionally, in describing the present invention, when it is said that a part "includes" a certain component, this does not mean that other components are excluded, but rather that other components can be further included, unless specifically stated otherwise.

[0023] Hereinafter, specific details according to the present invention will be described in detail with reference to the attached drawings.

[0024] FIG. 1 is a perspective view of a large-capacity capsule filter (10) according to one embodiment of the present invention, and FIG. 2 is an enlarged view of the upper cap (200) of the capsule filter.

[0025] Referring to FIGS. 1 and 2, a capsule filter (10), which is an embodiment of the present invention, is configured to include a case (100) that accommodates a filter for removing impurities contained in an inflow liquid, and an upper cap (200) in which an inlet (210), an outlet (220), and a check hole (230) are formed.

[0026] Inside the case (100), a cylindrical filter (not shown) made of at least one filtering member is accommodated to increase the filtration area.

[0027] The above case part (100) not only prevents deformation of the filter part accommodated inside, but also serves to fix the position thereof. The material of the case part (100) is not particularly limited, but may be manufactured from a polymer resin such as polypropylene.

[0028] In addition, the internal structure of the case part (100) is designed so that the inflow liquid containing impurities, which flows in through the inlet (210), can pass through the filter part and be transferred to the outlet (220).

[0029] According to Fig. 2, the upper cap (200) coupled with the case portion (100) is formed with an inlet (210) through which the inlet liquid flows in, an outlet (220) through which the filtered liquid with impurities removed is discharged, and a check hole (230).

[0030] The positions of the inlet (210) and outlet (220) are formed symmetrically left and right with respect to the center of the upper cap (200) to optimize the structure of the capsule filter (10).

[0031] As explained above, in conventional capsule filters, an outlet is formed in the center of the container, and a filtering section exists in a manner that entirely surrounds the outlet, and an inlet is inevitably placed on the periphery of the filtering section, so the horizontal cross-sectional area of ​​the capsule filter inevitably has to be wide.

[0032] On the other hand, the present invention can reduce the cross-sectional area of ​​the capsule filter, i.e., the outermost diameter, by arranging the inlet and outlet symmetrically on the left and right and positioning the filtering part in the center, thereby minimizing the installation area of ​​the capsule filter.

[0033] In addition, the diameters of the inlet (210) and outlet (220) formed in the upper cap (200) of the present invention can be designed to be the same size as the outer diameter (OD: 50.8 mm) of a 2-inch standard pipe, but the size is not limited thereto.

[0034] In this way, by adjusting the diameter of the inlet (210) and outlet (220) to the diameter of the standard pipe, it becomes suitable for general processes using 2-inch standard pipe, and an increase in discharge flow rate of up to 108% or more can be achieved compared to other companies. In other words, it is possible to process and discharge inlet liquid containing a large amount of impurities.

[0035] Meanwhile, in order to prevent operator's misdirection when installing the capsule filter (10) inside the housing (400) by turning it over, a concave check hole (230) is formed in a position close to the inlet (210) in the upper cap (200) of the present invention.

[0036] That is, when a worker installs the capsule filter (10) of the present invention into a housing (400) as depicted in FIG. 3, the inlet (210) and outlet (220) of the upper cap (200) are identical in shape and size, so if there is no check hole (230), there is a possibility that the worker may momentarily mistake which side is the inlet and which side is the outlet.

[0037] If the worker mistakenly connects the capsule filter (10) and the housing (400) in the direction of the inlet to the discharge pipe (420) and the discharge to the direction of the inlet pipe (410), not only will the filtering of impurities in the inlet liquid not be performed properly, but the discharge water will also contain impurities, which will inevitably cause defects in subsequent processes that utilize the discharge water.

[0038] Therefore, when a worker installs a capsule filter (10) into a housing (400), it must be checked in advance to avoid incorrect installation. To this end, the upper cap (200) of the present invention has a check hole (230) positioned close to the inlet (210), thereby allowing the worker to easily check the direction of the inlet (210) and the outlet (220) with the naked eye.

[0039] In addition, in order to double prevent operator error, a convex check bar (430) is protruded at the bottom of the housing (400) in which the capsule filter (10) is installed, as shown in Fig. 3 (a), so that when the capsule filter (10) is installed correctly, the check bar (430) of the housing and the check hole (230) of the capsule filter are fitted together, and if it is installed incorrectly, the capsule filter (10) cannot be properly fixed in the housing (400) due to the check bar (430).

[0040] As a result, the capsule filter (10) of the present invention includes an inlet (210) and an outlet (220) of a left-right symmetrical structure, but can be installed in the housing without error due to the presence of a check hole (230).

[0041] Meanwhile, referring to FIG. 4, a first check valve (211) and a second check valve (221) are installed in the inlet (210) and the outlet (220), respectively, to open or close the inlet (210) or the outlet (220) according to the elastic deformation of the spring.

[0042] That is, when the filter (10) is installed in the correct position connected to the pipe of the housing (400), the springs of the first check valve (211) and the second check valve (221) are compressed, thereby opening the inlet (210) and the outlet (220).

[0043] In this open state, the inflow and outflow water move inside and outside the capsule filter (10).

[0044] Conversely, when the filter (10) is detached from the housing (400), the springs of the first check valve (211) and the second check valve (221) expand, thereby closing the inlet (210) and the outlet (220).

[0045] From this, the contents inside the capsule filter (10) are prevented from leaking out.

[0046] Although the present invention has been described above with reference to one embodiment, it will be understood by those skilled in the art that various modifications and changes can be made to the present invention without departing from the spirit and scope of the present invention as set forth in the claims below.
