Description

Technical Field

[0001] This invention relates to a large-capacity capsule filter, and more specifically, to a large-capacity capsule filter that receives inflow liquid, removes impurities, and discharges it. Background Technology

[0002] Filters are typically used to filter impurities or various pollutants that are harmful to the human body from liquid or gaseous fluids, and are widely used in various fields such as industrial and household applications.

[0003] However, with the specialization and precision development of the filter industry, there is a need to design capsule filters that are both economical and highly efficient. In particular, recently developed and commercially available filters are manufactured in the form of capsule filters and housed in a housing with specific dimensions. Therefore, while increasing filtration capacity, the installation area can be minimized. It can be said that developing economical and space-saving capsule filters has become an urgent task.

[0004] However, as shown in the prior art patent documents below, conventional capsule filters adopt a design in which an outlet is formed in the center, a filter section is arranged in a manner that surrounds the outlet, and an inlet is arranged around the filter section. Therefore, it inevitably leads to the limitation that the cross-sectional area (i.e., the installation area) of the capsule filter is increased.

[0005] In addition, due to the structural design of capsule filters, the inlet and outlet of the filter are not compatible with conventional pipe specifications, making it difficult to handle large volumes of inflow liquid. Summary of the Invention

[0006] Technical issues

[0007] According to traditional capsule filters, the cross-sectional area needs to reach a certain size, which inevitably increases the size of the outer shell, resulting in shortcomings in terms of economy or inflow liquid treatment.

[0008] Therefore, the purpose of this invention is to solve the above problems and provide a large-capacity capsule filter that, while minimizing the installation area, relatively increases the filtration area, thereby doubling the filtration flow rate.

[0009] Problem Solution

[0010] To address the aforementioned problem, the present invention provides a capsule filter comprising: a housing portion having an internal space for accommodating a filter portion, and an upper cover covering the upper surface of the housing portion; the filter portion removing impurities included in the inflow liquid; and the upper cover having an inlet for the inflow liquid to flow in, an outlet for discharging the filtered liquid with impurities removed, and an inspection hole.

[0011] According to one embodiment, the present invention is characterized in that the inlet and the outlet are formed in a structure that is symmetrical about the center of the upper cover.

[0012] According to another embodiment, the present invention is characterized in that the inlet is opened or closed by a first check valve, and the outlet is opened or closed by a second check valve.

[0013] According to yet another embodiment, the invention is characterized in that the inspection hole is formed to prevent misinstallation by the operator when installing the capsule filter onto the housing.

[0014] Invention Effects

[0015] The large-capacity capsule filter according to the present invention can minimize the installation area, increase the filtration area, and enable the operator to install the housing accurately.

[0016] Furthermore, the effects of the present invention are not limited to those mentioned above, and those skilled in the art can clearly understand other effects not mentioned from the following description. Attached Figure Description

[0021] This application claims priority to Korean Patent Application No. 10-2024-0102832, dated August 24, 2024, the contents of which are incorporated herein by reference.

[0022] The description of this invention is merely for structural or functional purposes and therefore the scope of the invention should not be construed as limited to the embodiments described herein. That is, embodiments can be modified in various ways and have various forms; therefore, it should be understood that the scope of the invention includes equivalents capable of implementing the technical concept.

[0023] Furthermore, the objectives or effects proposed in this invention do not imply that a particular embodiment must include all or only these objectives or effects; therefore, the scope of the invention should not be construed as limited thereto.

[0024] When describing the constituent elements of the present invention, if it is stated that a constituent element is "connected", "combined" or "coupled" with another constituent element, it should be understood that the constituent element can be directly connected or coupled with the other constituent element, but it is also possible that another constituent element is "connected", "combined" or "coupled" between the constituent elements.

[0025] Furthermore, when describing the present invention, when referring to a part as "including" a certain constituent element, it means that other constituent elements are not excluded, but may be further included, unless otherwise expressly stated to the contrary.

[0026] The specific content of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] Figure 1 This is a perspective view of a large-capacity capsule filter 10 according to an embodiment of the present invention. Figure 2 This is an enlarged view of the top cover 200 of the capsule filter.

[0028] Reference Figure 1 and Figure 2 As shown, the capsule filter 10, as an embodiment of the present invention, includes: a housing portion 100, which houses a filter portion for removing impurities contained in the inflow liquid; and an upper cover 200, which has an inlet 210, an outlet 220 and an inspection hole 230.

[0029] The housing portion 100 internally houses a cylindrical filter portion (not shown), which is composed of at least one filter element, thereby increasing the filtration area.

[0030] The housing portion 100 not only prevents the filter portion housed inside from deforming, but also serves to stabilize and fix the position of the filter portion. The material of the housing portion 100 is not particularly limited and can be made of polymer resins such as polypropylene.

[0031] Furthermore, the internal structure of the housing 100 is designed to enable the following functions: allowing the inflow liquid to flow in through the inlet 210 in a state containing impurities, flow through the filter section and be transferred to the outlet 220.

[0032] according to Figure 2 The upper cover 200, which is connected to the housing part 100, has an inlet 210 for the inflow of liquid, an outlet 220 for the discharge of filtered liquid from which impurities have been removed, and an inspection hole 230.

[0033] The inlet 210 and outlet 220 are positioned in a symmetrical structure with the center of the upper cover 200 as a reference, so as to optimize the structure of the capsule filter 10.

[0034] As described above, in a conventional capsule filter, an outlet is formed in the center of the container, and the filter section is arranged to completely surround the outlet. The inlet is inevitably located on the periphery of the filter section, which inevitably leads to an increase in the cross-sectional area of ​​the capsule filter.

[0035] Conversely, the present invention configures the inlet and outlet as a symmetrical structure and provides a filter section in the central part, thereby reducing the cross-sectional area (i.e., the outermost diameter) of the capsule filter and ultimately minimizing the installation area of ​​the capsule filter.

[0036] Furthermore, the inlet 210 and outlet 220 of the upper cover 200 formed in this invention can be designed to match the same size as the outer diameter of a 2-inch standard pipe (OD of 50.8 mm), but their size is not limited thereto.

[0037] By matching the diameters of the inlet 210 and outlet 220 with those of standard piping, making it suitable for conventional processes using 2-inch standard piping, it achieves a discharge flow rate increase of up to 108% compared to other companies' products. In other words, it can handle and discharge large volumes of inflow liquid containing impurities.

[0038] On the other hand, in the upper cover 200 of the present invention, a recessed inspection hole 230 is formed near the inlet 210 to prevent the operator from making a wrong orientation when flipping the capsule filter 10 into the housing 400.

[0039] That is, such as Figure 3 As shown, when the operator places the capsule filter 10 of the present invention on the housing 400, since the inlet 210 and outlet 220 of the upper cover 200 have the same shape and size, the operator may momentarily confuse which side is the inlet and which side is the outlet if there is no inspection hole 230.

[0040] If the operator incorrectly connects the capsule filter 10 to the housing 400, that is, the inlet is facing the discharge pipe 420 and the outlet is facing the inlet pipe 410, not only will the filtration of impurities in the inflow liquid fail to be achieved normally, but the discharge water will also contain impurities, which will inevitably lead to problems in subsequent processes using the discharge water.

[0041] Therefore, when the operator sets the capsule filter 10 on the housing 400, it is necessary to check in advance whether there is an error in the setting. To this end, the upper cover 200 of the present invention has the inspection hole 230 located near the inlet 210, so that the operator can easily check the direction of the inlet 210 and the outlet 220 with the naked eye.

[0042] In addition, to double prevent operator errors, such as Figure 3 As shown in part (a), a protruding inspection strip 430 is formed at the lower end of the housing 400 used to install the capsule filter 10. Therefore, when the capsule filter 10 is installed correctly, the inspection strip 430 of the housing is engaged with the inspection hole 230 of the capsule filter in a fitting manner. However, when the installation is incorrect, the capsule filter 10 cannot be accurately fixed inside the housing 400 due to the presence of the inspection strip 430.

[0043] Therefore, the capsule filter 10 of the present invention includes an inlet 210 and an outlet 220 with a left-right symmetrical structure, but due to the presence of the inspection hole 230, it can be accurately set in the outer shell.

[0044] On the other hand, refer to Figure 4 A first check valve 211 and a second check valve 221 are respectively provided at the inlet 210 and the outlet 220, and the inlet 210 or the outlet 220 is opened or closed according to the elastic deformation of the spring.

[0045] That is, when the filter 10 is installed in the correct position where it is 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.

[0046] In this open state, the inflow and outflow water move inside and outside the capsule filter 10.

[0047] Conversely, when the filter 10 is removed 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.

[0048] This prevents the contents inside the capsule filter 10 from leaking to the outside.

[0049] The above description refers to an embodiment of the present invention. However, those skilled in the art should understand that various modifications and alterations can be made to the present invention without departing from the spirit and scope of the invention as set forth in the appended claims.
