Example 1
[0022] Please see Figures 1-2 This utility model discloses an impact-resistant multilayer metal filter element structure for extreme working conditions, including a filter element 1, one end of which is provided with a pressure-reducing component 70 for pressure reduction, wherein:
[0023] The pressure reducing assembly 70 includes an input end 71 for connecting to a pipe containing the material to be filtered.

A dispersing plate 73 is provided on the inner wall of the pressure reducing chamber 72. A support frame 74 is installed on one side of the dispersing plate 73. A gathering pipe 75 is installed on the inner wall of the pressure reducing chamber 72 for concentrating the material to be filtered. An acceleration chamber 76 is provided on the inner wall of the gathering pipe 75.
[0024] The outer surface of the filter element 1 is fitted with an inlet end 2, one end of which is fitted with an inner core 3. The outer surface of the inner core 3 is fitted with a diverging tube 4, the outer surface of the diverging tube 4 is fitted with an outer core 5, and the outer surface of the outer core 5 is fitted with a shell 6.
[0025] The inlet 2 and the inner core 3 are interconnected. The two ends of the inner core 3 are fixedly connected to the two ends of the inner wall of the filter element 1. The outer surface of the inner core 3 is in contact with the inner wall of the radiating tube 4. The outer surface of the radiating tube 4 has several holes for discharging primary filtration.
[0026] The material first enters the pressure-reducing chamber 72, where the dispersing plates 73 on the inner wall are fixed by the support frame 74, cutting and dispersing the high-speed flowing stream of material to be filtered, thus breaking its impact force. The support frame 74 provides structural stability, preventing the dispersing plates 73 from deforming under high pressure. The dispersed material is then concentrated and guided by the collecting tube 75, which is fixed to the inner wall of the pressure-reducing chamber 72, forming a gradually narrowing channel. After entering the acceleration chamber 76, the cross-sectional area of the channel decreases, the flow velocity increases, and a turbulent state is formed, further enhancing the solid-liquid separation effect. Example 2
[0027] Based on the above embodiment 1, please refer to Figures 3-5 The outer surface of the diverging tube 4 is in contact with the inner wall of the outer core 5.

The two ends of the diverging tube 4 are fixedly connected to the two ends of the inner wall of the filter element 1. One end of the filter element 1 is fixedly connected to the inner wall of the outer shell 6.

The inner wall of the acceleration chamber 76 is connected to the inner wall of the access end 2.
[0031] The accelerated material enters the inner core 3 through the inlet 2. The inner core is fixed to the inner wall of the filter element 1, forming the first radial filtration. The unfiltered fluid enters the annular space between the outer core 5 and the outer shell 6 through the pores of the divergence tube 4, completing the secondary filtration. The multi-layer structure (inner core → divergence tube → outer core) achieves gradient filtration, with large particles being intercepted layer by layer, and fine particles being discharged through the outer shell 6.
[0032] The working principle and usage process of this utility model are as follows: The material to be filtered enters the pressure reducing component 70 through the input end 71.

[0034] Convergence and Acceleration: The dispersed material is concentrated and guided by the convergence tube 75, which is fixed to the inner wall of the decompression chamber 72, forming a gradually narrowing channel. After the material enters the acceleration chamber 76, the cross-sectional area of the channel decreases, the flow velocity increases, and a turbulent state is formed, further enhancing the solid-liquid separation effect.
[0035] Multi-layer filtration process: The accelerated material enters the inner core 3 through the inlet 2. The inner core is fixed to the inner wall of the filter element 1, forming the first radial filtration. The unfiltered fluid enters the annular space between the outer core 5 and the outer shell 6 through the pores of the diverging tube 4, completing the secondary filtration. The multi-layer structure (inner core → diverging tube → outer core) achieves gradient filtration, with large particles being intercepted layer by layer, and fine particles being discharged through the outer shell 6.
[0036] Sludge removal and circulation: The filtered clean fluid is discharged through outlet 6 of the outer shell. The intercepted solid particles are deposited in each layer of the filter element and are cleaned and maintained regularly by backwashing or disassembly.
