It combines deep filtration, high precision, high flow rate, strong mechanical properties, and excellent temperature and corrosion resistance, making it suitable for industrial filtration applications with extremely high reliability requirements. It is the preferred solution for high-temperature, corrosive, and high-pressure environments.

[0003] Chinese Patent CN222765747U discloses a multi-layer metal fiber sintered felt, comprising a fiber sintered felt sleeve for bonding and a metal composite layer for filtration, with the metal composite layer fitted inside the fiber sintered felt sleeve. Two sets of rotating handles are provided on both sides of the fiber sintered felt sleeve. This multi-layer metal fiber sintered felt, through the fiber sintered felt sleeve, ensures a secure bonding of the fiber sintered felt, preventing the composite layer from spreading and affecting the filtration effect. The rotating handles facilitate the handling and movement of the fiber sintered felt, increasing the flexibility of the device. The metal composite layer, with its multiple structural components, enhances filtration performance.

[0004] However, the above technical solution has the following shortcomings: when the fiber sintered felt is sleeved, the fiber sintered felt sleeve is an integral structure, which makes it very inconvenient to place the composite layer and replace it after placement, thus reducing the convenience of use.

One end of the insert rod is inserted into the interior of the lower shell and penetrates the through hole. A groove for the guide slider to slide on the fixing frame is provided, and the first spring is sleeved on the insert rod.

[0007] Preferably, the lower housing is provided with a placement groove, and a metal composite layer is provided in the placement groove.

[0008] Preferably, the metal composite layer includes a first composite layer disposed on the outermost side, a second composite layer disposed inside the first composite layer, a third composite layer disposed inside the second composite layer, and a fourth composite layer disposed on the innermost side.

[0009] Preferably, a grip ball is provided at the end of the insertion rod away from the lower housing.

[0010] Preferably, the upper shell is provided with four symmetrically distributed positioning posts, and the lower shell is provided with positioning holes that are compatible with the positioning posts.

[0011] Preferably, the upper housing is provided with two clamping assemblies, each clamping assembly including a plurality of second springs linearly distributed inside the upper housing and a pressure plate disposed on the second springs.

[0012] Preferably, the upper housing has a plurality of stabilizer bars inside, each corresponding to a second spring, and the second spring is sleeved on the stabilizer bars.

[0013] Preferably, the lower housing is provided with two rotatably connected handles.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0022] Example 1

[0023] like Figures 1-5 As shown, the metal fiber sintered felt with filter proposed in this embodiment includes a lower shell 1 and a fixing mechanism; an upper shell 2 is provided on the lower shell 1, and two symmetrically distributed inserts 5 with two through holes 6 are provided on the upper shell 2. A rectangular groove for inserts 5 to be inserted is provided on the lower shell 1, and two rotatably connected handles 20 are provided on the lower shell 1. During transportation, the handles 20 can be rotated first until the handles 20 abut against the lower shell 1, and then the metal composite layer 4 can be transported and transferred.

[0024] The fixing mechanism includes four fixing frames 7 symmetrically distributed on the lower housing 1, a plug rod 8 slidably connected to the fixing frame 7 and having two limiting holes 14, a convex ring 9 coaxially arranged on the plug rod 8, a first spring 12 with its two ends respectively arranged on the convex ring 9 and the fixing frame 7, two connecting rods 10 arranged on the convex ring 9, a guide slider 11 arranged on the connecting rod 10, and a pin 15 penetrating through the limiting hole 14; one end of the plug rod 8 is inserted into the interior of the lower housing 1 and is arranged through the through hole 6, the fixing frame 7 is provided with a sliding groove for the guide slider 11 to slide, the first spring 12 is sleeved on the plug rod 8, and a ball grip 13 is provided at the end of the plug rod 8 away from the lower housing 1.

[0025] In this embodiment, when it is necessary to close and fix the lower housing 1 and the upper housing 2, the insert block 5 on the upper housing 2 is first inserted into the rectangular groove of the lower housing 1, and then the pin 15 is pulled out from the limiting hole 14 on one side. Since the first spring 12 is in a compressed state at this time, after the limiting effect of the pin 15 is lost, the first spring 12 will push the convex ring 9 and the insert rod 8 to move, and cooperate with the connecting rod 10 and the guide slider 11 to guide and stabilize the movement of the insert rod 8 until the insert rod 8 passes through the through hole 6 on the insert block 5. Finally, the pin 15 is inserted into the limiting hole 14 on the other side to further stabilize it. At this time, the first spring 12 is still in a compressed state, thus completing the fixing operation of the lower housing 1 and the upper housing 2. The operation is not only simple and convenient, but also has a good fixing effect, which facilitates the installation and replacement of the metal composite layer 4, improves the usability of the structure, and has good practicality.

The metal composite layer 4 includes a first composite layer 21 disposed on the outermost side, a second composite layer 22 disposed on the inner side of the first composite layer 21, a third composite layer 23 disposed on the inner side of the second composite layer 22, and a fourth composite layer 24 disposed on the innermost side.

[0028] In this embodiment, the placement groove 3 and the metal composite layer 4 are adapted to each other to achieve placement processing. The first composite layer 21 is formed by compaction and sintering of a composite layout, the second composite layer 22 is formed by staggered layout sintering, the third composite layer 23 is formed by trapezoidal layout sintering, and the fourth composite layer 24 is formed by unidirectional layout sintering. The multiple composite layers are used together to perform filtration processing, and the composite layer structure disclosed in the prior art is adopted.

[0031] In this embodiment, when the upper housing 2 is closed, the positioning pin 16 is inserted into the positioning hole on the lower housing 1, which not only provides positioning but also improves the stability of the connection. When the pressure plate 18 on the upper housing 2 is pressed against the edge of the metal composite layer 4, the second spring 17 provides distance compensation to further improve the stability of the metal composite layer 4 after installation. The stabilizing rod 19 guides the extension and retraction of the second spring 17, preventing the second spring 17 from bending or twisting.
