Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a multi-layer metal wire mesh sintered filter. Background Technology

[0002] As the main internal structure of a filter, the filter disc plays a role in filtering fluids. During use, the filter disc is installed and fixed inside the filter, so that impurities can be filtered out when the fluid flows through the filter disc inside the filter.

[0003] A search revealed that utility model patent CN212091277U discloses an easy-to-install metal fiber sintered felt filter, comprising an outer ring, an inner ring, a connecting rod, a mounting hole, an inner filter screen, an inclined support frame, a rubber ring, a sleeve post, an inclined body, a central hole, and an outer filter screen. The outer ring is fixed at the upper end of the inclined support frame, and the inclined support frame is installed at the lower end of the filter. The inclined support frame allows the filter to be in an inclined state.

[0004] However, the above-mentioned filter plates still have some drawbacks in actual use. The most obvious one is that due to the uneven distribution of impurities in the fluid, the inner and outer filter screens often experience local wear during the filtration process, which leads to a decrease in filtration efficiency. At this time, it is necessary to replace the inner and outer filter screens as a whole. However, since the wear often occurs locally, replacing the whole screen not only causes waste but also increases the filtration cost.

[0005] Therefore, it is necessary to invent a multi-layer metal wire mesh sintered filter to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a multi-layer metal wire mesh sintered filter sheet, which allows for individual replacement of any one of the fan-shaped filter screens after wear, thereby avoiding the waste caused by replacing the entire filter screen and effectively reducing filtration costs. It is also more convenient in practical use, addressing the issue mentioned in the background art where uneven distribution of impurities in the fluid often leads to localized wear of the inner and outer filter screens during filtration, resulting in decreased filtration efficiency. In such cases, replacing the entire filter screen is necessary, but since wear often occurs locally, overall replacement not only causes waste but also increases filtration costs.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a multilayer metal wire mesh sintered filter sheet, comprising:

[0008] A support mechanism, which is used to support the filtration mechanism;

[0009] The filtration mechanism includes four sets of filter components arranged in a ring. Each set of filter components includes a fan-shaped filter screen made of multiple layers of metal wire mesh sintered together. A first positioning protrusion is integrally formed on the outer center of the fan-shaped filter screen.

[0010] A clamping mechanism, used to clamp and seal the filter mechanism; and

[0011] A locking mechanism is provided for locking the supporting mechanism and the pressing mechanism.

[0012] According to at least one embodiment of the multilayer metal wire mesh sintered filter sheet of the present disclosure, the supporting mechanism includes a mounting ring, mounting holes and positioning grooves, and four mounting holes and four positioning grooves are provided. The four mounting holes are evenly disposed through the top of the mounting ring, and the four positioning grooves are evenly opened on the inner side of the mounting ring.

[0013] According to at least one embodiment of the multilayer metal wire mesh sintered filter sheet of the present disclosure, the supporting mechanism further includes a limiting ring, a central column and a first connecting rod. The limiting ring is fixedly disposed at the bottom of the inner side of the mounting ring, the central column is located at the center of the inner side of the limiting ring, and four first connecting rods are provided, which are evenly fixedly disposed between the limiting ring and the central column.

[0014] According to at least one embodiment of the multilayer metal wire mesh sintered filter sheet of this disclosure, the pressing mechanism includes a center plate, a limiting channel, a second connecting rod, a pressing ring, and a second positioning protrusion. The center plate is pressed against the top of the inner ends of four fan-shaped filter screens. The limiting channel is disposed through the center of the top of the center plate. Four second connecting rods are provided, and the four second connecting rods are evenly fixedly disposed on the outside of the center plate. The pressing ring is fixedly sleeved on the outside of the four second connecting rods. Four second positioning protrusions are provided, and the four second positioning protrusions are evenly fixedly disposed on the outside of the pressing ring.

[0015] According to at least one embodiment of the multilayer metal wire mesh sintered filter sheet of the present disclosure, the locking mechanism includes a limiting block, a stud, and a nut. The limiting block is fixedly disposed on the top of the central column, the stud is fixedly disposed on the top of the limiting block, and the nut is sleeved on the outer top of the stud and threadedly connected to the stud.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features four sets of ring-shaped filter components. When any one of the sector-shaped filters needs replacement due to wear, the nut can be unscrewed from the outside of the stud, and then the entire clamping mechanism can be lifted upwards to release the clamping mechanism from the four sector-shaped filters. Finally, the sector-shaped filter to be replaced can be removed, a new sector-shaped filter can be placed, and the clamping mechanism and nut can be reset. Compared with existing similar products, this invention allows for the individual replacement of any one sector-shaped filter after wear, thus avoiding the waste caused by replacing the entire filter and effectively reducing filtration costs. It is also more convenient in actual use. Attached Figure Description

[0027] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0028] Figure 1 This is a schematic diagram of the overall structure of a multilayer metal wire mesh sintered filter sheet according to one embodiment of the present disclosure.

[0029] Figure 2 This is a schematic diagram of the support mechanism 1 and locking mechanism 4 of a multilayer metal wire mesh sintered filter according to one embodiment of the present disclosure.

[0030] Figure 3 This is a schematic diagram of the filter mechanism 2 and the pressing mechanism 3 of a multilayer metal wire mesh sintered filter according to one embodiment of the present disclosure.

[0031] like Figures 1-3 As shown, the multilayer metal wire mesh sintered filter sheet disclosed herein may include components such as a support mechanism 1, a filtering mechanism 2, a pressing mechanism 3, and a locking mechanism 4.

[0032] like Figure 2 As shown in this disclosure, the supporting mechanism 1 includes a mounting ring 11, mounting holes 12, positioning grooves 13, limiting rings 14, a central column 15, and first connecting rods 16. The mounting holes 12 and positioning grooves 13 are each provided with four holes. The four mounting holes 12 are evenly distributed through the top of the mounting ring 11, and the four positioning grooves 13 are evenly distributed inside the mounting ring 11. The limiting ring 14 is fixedly disposed at the bottom inner side of the mounting ring 11, and the central column 15 is located at the center of the inner side of the limiting ring 14. Four first connecting rods 16 are provided, and the four first connecting rods 16 are evenly fixedly disposed between the limiting ring 14 and the central column 15.

[0033] Therefore, the assembled product can be installed using the mounting holes 12, and the positioning groove 13 can be used to position the filter mechanism 2 and the pressing mechanism 3 during the installation process, thereby reducing the installation difficulty and ensuring the installation accuracy.

[0034] like Figure 3 As shown, in a preferred embodiment, the filtration mechanism 2 includes four sets of filter components arranged in a ring. Each set of filter components includes a fan-shaped filter screen 21 made of multiple layers of metal wire mesh sintered together. A first positioning protrusion 22 is integrally formed on the outer center of the fan-shaped filter screen 21.

[0035] Therefore, when any one of the sector-shaped filter screens 21 needs to be replaced due to wear, the nut 43 can be unscrewed from the outside of the stud 42, and then the clamping mechanism 3 can be lifted upwards to release the clamping mechanism 3 from the four sector-shaped filter screens 21. Finally, the sector-shaped filter screen 21 to be replaced can be removed, and a new sector-shaped filter screen 21 can be placed. Then, the clamping mechanism 3 and the nut 43 can be reset. Compared with existing similar products, any one of the sector-shaped filter screens 21 can be replaced individually after it wears out, thus avoiding the waste caused by replacing the whole screen and effectively reducing filtration costs. It is also more convenient in actual use.

[0036] like Figure 3 As shown in this disclosure, the pressing mechanism 3 includes a center plate 31, a limiting channel 32, a second connecting rod 33, a pressing ring 34, and a second positioning protrusion 35. The center plate 31 is pressed against the top of the inner end of four fan-shaped filter screens 21. The limiting channel 32 is disposed through the center of the top of the center plate 31. Four second connecting rods 33 are provided and are evenly fixedly disposed on the outside of the center plate 31. The pressing ring 34 is fixedly sleeved on the outside of the four second connecting rods 33. Four second positioning protrusions 35 are provided and are evenly fixedly disposed on the outside of the pressing ring 34.

[0037] Thus, the center plate 31 is sleeved on the outside of the limiting block 41 through the limiting channel 32. At this time, any one of the second connecting rods 33 presses and seals the two adjacent fan-shaped filter screens 21, and the four second positioning protrusions 35 enter the inside of the four positioning grooves 13 respectively.

[0038] like Figure 2 As shown, in a preferred embodiment, the locking mechanism 4 includes a limiting block 41, a stud 42, and a nut 43. The limiting block 41 is fixedly disposed on the top of the central column 15, the stud 42 is fixedly disposed on the top of the limiting block 41, and the nut 43 is sleeved on the outer top end of the stud 42 and threadedly connected to the stud 42.

[0039] Therefore, the clamping mechanism 3 can be positioned by the limiting block 41, which facilitates the clamping mechanism 3 to enter the inner side of the mounting ring 11 to clamp the four fan-shaped filter screens 21. After the clamping mechanism 3 is assembled, the nut 43 sleeved on the outside of the stud 42 can clamp and lock the center plate 31.

[0040] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0041] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
