Description

Technical Field

[0001] The utility model belongs to the technical field of filters, and particularly relates to a segmented filter housing. Background Art

[0002] Currently, filter housings on the market are generally assembled from three main parts: a base, an upper section, and a filter element mounted on the base. The base is shorter and houses the filter element, which comes in a variety of sizes, with 5-inch, 10-inch, 20-inch, and 30-inch sizes being the most common. The upper section encloses the filter element, whose height is determined by the height of the element. The base is generally fixed, while the upper section is removable, facilitating later filter element replacement. For traditional 20-inch and 30-inch filter housings, the upper section can reach a height of approximately 680mm and 920mm, respectively. When removing the upper section, approximately 1400mm and 1800mm of clearance are required, respectively. This height is sometimes unattainable for pharmaceutical manufacturers due to their limited equipment installation environments. Therefore, traditional high-height filter housings often present the problem of excessive height when removing the upper section. Furthermore, the increased weight of the upper section of these high-height filter housings adds significant inconvenience to disassembly. Utility Model Content

[0003] In response to the above problems and technical needs, the present invention provides a segmented filter housing, which can solve the problems of high operating height and heavy weight when replacing the filter element of a large filter housing, reduce the difficulty of operation and improve the safety of operation.

[0004] The technical solution of the utility model is as follows: a segmented filter housing, comprising a base, a filter element, a segmented sealing cover, a first clamp and a second clamp, the filter element is clamped and installed on the base, the segmented sealing cover is sealed and connected to the base, and the filter element cover is arranged inside; the segmented sealing cover is divided into two parts, the upper half is a top cover, and the lower half is a cylindrical filter housing, and the cylindrical filter housing is correspondingly installed on the base, the cylindrical filter housing and the round edge of the base are compressed and sealed by the first clamp, and the upper port of the cylindrical filter housing is compressed and sealed by the second clamp, and the first clamp and the second clamp can be freely disassembled from the outside; a liquid inlet channel and a filtration flow channel are also provided in the base, wherein the filtration flow channel is correspondingly arranged at the bottom of the filter element, and the liquid flows into the space between the filter element and the segmented sealing cover through the liquid inlet channel, and after being filtered by the filter element, flows out from the filtration flow channel. The upper and lower halves of the segmented sealing cover are detachably connected and can be removed in sections during operation. The overall length is reduced by 1 / 2, which reduces the operating space required above the filter housing and reduces the weight borne during a single transport by nearly half, enabling installation in a small space.

[0005] Furthermore, a first flange joint is provided at the edge of the base, and a second flange joint is provided at the bottom port of the cylindrical filter housing. The first flange joint and the second flange joint are engaged with each other in a concave-convex manner. A lower sealing groove is provided on the inner side of the engaging surface. The first clamp surrounds and presses the first flange joint and the second flange joint from the outside, and a sealing ring is filled in the lower sealing groove.

[0006] Furthermore, the upper port of the cylindrical filter housing is provided with a third flange joint, and the lower port of the top cover shell is provided with a fourth flange joint. The third flange joint and the fourth flange joint are engaged with each other in a concave-convex manner, and an upper sealing groove is provided on the inner side of the engaging surface. The second clamp surrounds and presses the third flange joint and the fourth flange joint from the outside, and the upper sealing groove is filled with a sealing ring.

[0007] The two pairs of flange joints are engaged with each other in a concave-convex manner, and a sealing ring is provided on the inner side of the engagement. This not only makes the installation and positioning more accurate, but also improves the sealing effect and prevents the internal liquid from leaking out.

[0008] Furthermore, a pair of upper handles are symmetrically provided on both sides of the top cover, a cleaning port leading to the interior is provided at the top of the top cover, a sealing plug is installed on the cleaning port, and an exhaust port is provided on the side of the cleaning port. The provision of the cleaning port and the exhaust port facilitates exhausting, cleaning and sterilization of the filter housing.

[0009] Furthermore, a pair of lower handles are symmetrically provided on both sides of the cylindrical filter housing.

[0010] Furthermore, the base is provided with four support legs at the bottom. The liquid inlet channel and the filter flow channel lead from the bottom of the base into the segmented sealed housing. The four support legs provide installation space for the liquid inlet channel and the filter flow channel, supporting the entire filter housing to maintain stability. If necessary, the four support legs can be welded to the equipment to be filtered to improve filtration stability.

[0011] Furthermore, the base is mounted with multiple filter elements, evenly distributed around the center of the base. A media holding chamber is provided within the base, the bottom of which communicates with a filtration channel. An oblique channel connects the media holding chamber to each filter element. The oblique channel directs filtered liquid, funneling the liquid filtered by the multiple filter elements into the media holding chamber, where it then flows outward through the filtration channel.

[0012] Furthermore, a multi-layer sealing ring is provided at the connection between the filter element and the base. The multi-layer sealing ring can achieve a better sealing effect between the filter element and the base, and prevent unfiltered liquid from seeping into the filter element from the connection.

[0013] The beneficial effects of the present invention are as follows: the present invention divides the upper cover of the traditional filter housing into a two-section structure; the segmented sealing cover consists of a top cover and a cylindrical filter housing; the first clamp locks the base and the cylindrical filter housing, and the second clamp locks the cylindrical filter housing and the top cover; concave and convex bite portions and sealing rings are provided at the connection between the first and second flange joints, as well as the connection between the third and fourth flange joints, so as to ensure the precise positioning and sealing performance of the connection and avoid leakage at the connection; compared with the traditional filter housing, when replacing the filter element, the operating height of the segmented filter housing is reduced by half, the weight is reduced by nearly half, the maintenance difficulty is greatly reduced, and there is no need to reserve too high an operating space on the top, which significantly improves the application range of the filter housing and enables it to be perfectly installed and easily maintained in a small space.
