Description

Technical Field

[0001] The utility model relates to the technical field of purification equipment, in particular to a novel filler-type sintered mesh filter element. Background Art

[0002] Sintered mesh filter elements offer excellent permeability and strength; they require no support components and are free of material loss; they are heat-resistant and corrosion-resistant; and they are easy to clean and non-destructive. Based on their function, they are classified into surface filtration and depth filtration types. For example, sintered mesh filter elements are surface filtration sintered filter elements. Surface filtration types are generally made of sintered mesh, as sintered mesh provides surface filtration. Sintered filter elements made of fibers, particles, or granules, such as powder sintering and sintered felt, are depth filtration sintered filter elements. Examples include copper powder sintered filter elements, activated carbon sintered filter elements, and sintered felt filter elements. However, traditional sintered mesh filter elements are ineffective. Once the outer filter screen becomes severely clogged, their filtration and purification effectiveness is significantly reduced. The traditional approach involves replacing the entire filter element, but the inner filter screen has a much longer lifespan than the outer screen, making this approach wasteful and costly.

[0003] A query of the disclosed prior art "CN 209500919 U, a filler-type sintered mesh filter element" records that "the utility model mainly discloses a filler-type sintered mesh filter element, including an inner filter screen, an outer filter screen, a filter element end cover, a filter element pressure cover and a filter element pressure cover. The upper side of the outer filter screen is integrally connected to the filter element end cover, and a mounting port is provided in the middle of the filter element end cover. A filter element interface is provided on the mounting port. The filter element interface is connected to the interior of the inner filter screen. A cavity is formed between the inner filter screen and the outer filter screen, and filler particles are provided in the cavity. The lower side of the outer filter screen is detachably connected to the filter element pressure cover, and impurity particles in the liquid are removed by the filler particles to adsorb and purify the material. The lower side of the outer filter screen is detachably connected to the filter element pressure cover. The filter element pressure cover is a movable structure, and the filter element filler particles can be removed and replaced."

[0004] However, the aforementioned prior art sintered mesh filter element still has drawbacks: the outer filter screen and cover plate are connected by bolts. While this solves the problem of detachable connections to some extent, replacing the outer and inner filter screens is time-consuming and laborious, requiring external tools to remove and install the bolts, making filter replacement inefficient. Customers also frequently report that the bolts are easily lost during removal, making subsequent maintenance inconvenient. Summary of the Invention

In the absence of further restrictions, the phrase “including a…” or other limiting elements that may appear does not exclude the presence of other identical elements in the process, method, article or device that includes the elements.

[0022] In the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," and "provided with" that may appear should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0023] Example: Figures 1 to 4As shown: A new type of filler-type sintered mesh filter element, including an outer filter 1, an inner filter 2, an upper cover 3, and a lower cover 4. The utility model has a reasonable structural design, using a four-section split installation structure of filter, upper end cover, and lower end cover to construct the filter element unit skeleton. The inner filter 2 is arranged inside the outer filter 1, and the two are arranged coaxially; the inner filter 2 and the outer filter 1 are both arranged between the upper cover 3 and the lower cover 4, and the space between them is filled with filler particles 5. This is used to achieve that after the external gas completes the initial purification through the outer filter, it enters the area where the filler particles are located for deep purification, and then the external polluted air flow is purified and discharged through the secondary purification and filtration of the inner filter.

[0024] like Figure 2 As shown: In this embodiment, a connecting structure 6 is further provided between the outer filter 1 and the upper cover plate 3 and the lower cover plate 4. The connecting structure 6 includes a pad 7, a locking plate 8 and a spring 9. The pad 7 is an annular structure, and there are two symmetrically distributed ones, and they are fixedly installed at both ends of the outer filter 1 to form a skeleton unit of the outer filter; the pad is fixedly installed with the outer filter. A groove 10 is also provided on the pad 7. Specifically, a groove is provided on the upper end surface of the upper pad, and a groove is provided on the lower end surface of the lower pad. A vertically distributed first ratchet plate 11 is provided on the side wall of the groove 10, and a plurality of evenly distributed ratchets are distributed on the first ratchet plate. A mounting hole 12 is provided on the upper cover 3, and the mounting hole 12 is distributed through; wherein, the mounting hole corresponds to the position of the groove. The locking plate 8 is provided in the mounting hole 12, and the two can be relatively deflected. Specifically, telescopic sleeves 15 are also provided on both sides of the middle part of the locking plate 8. Among them, as Figure 4 As shown: the telescopic sleeve 15 includes a sleeve 16, a connecting column 17 and a compression spring 18; the connecting column 17 is fixedly installed on the locking plate 8, and the sleeve 16 is sleeved and installed on the connecting column 17, and the two can move relative to each other but cannot rotate relative to each other; the compression spring 18 is arranged on the sleeve 16, and one end is connected to the connecting column 17, and the other end is arranged on the inner wall of the sleeve 16. A slot 19 for adapting to the installation of the sleeve 16 is also provided on the side wall of the mounting hole 12. The purpose of this arrangement is to facilitate the installation of the locking plate at the specified position of the mounting hole through the telescopic characteristics of the telescopic sleeve, providing a strong foundation for the subsequent cooperation between the second ratchet and the first ratchet plate. The upper end surface of the locking plate 8 does not exceed the upper end surface of the upper cover plate 3. The purpose of this arrangement is to ensure the overall integrity and aesthetics of the sintered mesh filter element.

[0025] like Figure 2As shown: In this embodiment, the front end of the locking plate 8 is provided with a second ratchet 13, which cooperates with the first ratchet plate 11 to achieve unidirectional movement and locking. The spring 9 has one end disposed on the side wall of the mounting hole 12 and the other end connected to the locking plate 8 to unlock the second ratchet 13 from the first ratchet plate 11. The spring is located near the upper end of the locking plate and has a sufficiently strong elastic force. This configuration is intended to assist the locking plate in completing the unidirectional movement of the second ratchet and the first ratchet plate in the initial state, thereby locking the cover plate and the outer filter. Furthermore, when maintenance or replacement of the filter screen or filler particles is required, the upper end of the locking plate can be pressed to separate the second ratchet and the first ratchet plate, thereby completing the disassembly of the cover plate and the outer filter. In the initial state, the spring naturally extends, and the upper end of the locking plate is close to the right side wall of the mounting hole, which means that the locking plate is tilted downward and to the left.

[0026] like Figure 3 As shown: In this embodiment, the structural particularity of the inner filter is taken into consideration, that is, the inner filter has a low frequency of replacement and a long service life; at the same time, the structural distribution is located in the center of the entire filter element. The inner filter 2 is connected to the upper cover plate 3 and the lower cover plate 4 by a guide member 14. Among them, the guide member 14 includes a support plate 20, a guide column 21, and a guide hole 22. The support plates 20 are two symmetrically distributed up and down, and are fixedly installed at the upper and lower ends of the inner filter 2; the support plate is also a ring structure. The guide column 21 is arranged on the upper cover plate 3 and extends downward, and the two are an integrally formed structure; the guide hole 22 is opened on the support plate 20, and the guide hole 22 is matched with the guide column 21. With this arrangement, the positional relationship connection between the inner filter structure and the cover plate can be completed by auxiliary matching through a simple guide distribution, and the inner edge of the cover plate presses the support plate.

[0027] In this embodiment, the connection structure 6 between the outer filter 1 and the upper cover plate 3 and the lower cover plate 4 is symmetrically distributed in two groups. The guide members 14 at the inner filter 2 are evenly distributed in four groups; the guide members 14 are also symmetrically distributed between the outer filter 1 and the upper cover plate 3 and the lower cover plate 4. The sintered mesh filter element adopts a connection structure composed of a pad, a locking plate and a spring. The second ratchet and the first ratchet plate cooperate in one direction to complete the fastening installation between the outer filter and the cover plate. At the same time, the purpose of using the spring is to facilitate unlocking the locking state, conveniently and efficiently completing the separation of the outer filter, and avoiding the time-consuming and labor-intensive problem of using traditional bolts to replace the filter; the structure is simple and easy to assemble. The inner and outer filter screens, filler particles, etc. can be conveniently disassembled and replaced, which reduces the user's use cost, is more cost-effective, and more practical.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
