[0025] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0027] In related technologies, filtration devices often use filter paper or filter screens for filtration. However, these materials are easily damaged in high temperature, high pressure or corrosive environments, making it difficult for the filtration devices to adapt to the filtration needs of various complex environments, and the service life of the filtration devices is relatively short.

[0028] In response, this utility model proposes a porous foam metal filter device 100.

[0029] The following is for reference. Figures 1-3 The porous foam metal filtration device 100 according to an embodiment of the present invention includes: a filter tank 10 and a filter element 30.

[0030] A filtration space 11 is formed inside the filter tank 10, and as follows: Figure 1As shown, the filter tank 10 has an inlet 21 and an outlet 22 at both ends in the first direction. Both the inlet 21 and the outlet 22 are selectively connected to the filter space 11, such as... Figure 2 As shown, the filter element 30 is installed in the filter space 11. In the first direction, the filter element 30 is arranged opposite to the water inlet 21 and is located between the water inlet 21 and the water outlet 22. The filter element 30 is made of porous foam metal, and in the direction from the geometric center of the filter element 30 to the edge of the filter element 30, at least a portion of the filter element 30 is at a distance from the water inlet 21 that tends to increase.

[0031] Understandably, the liquid to be filtered enters the filtration space 11 through the inlet 21, and then is discharged through the outlet 22 after being filtered by the porous foam metal. Here, foam metal refers to a special metal material containing foam pores. Through its unique structural characteristics, foam metal possesses a series of advantages, including low density, good thermal insulation, good sound insulation, good mechanical strength, high temperature resistance, corrosion resistance, and the ability to absorb electromagnetic waves. Porous foam metal specifically refers to a type of foam metal with high porosity; therefore, porous foam metal exhibits high porosity, good mechanical strength, and high temperature and corrosion resistance. Porosity refers to the ratio of the volume of all pores in a porous body to the total volume of the porous body, often used to measure the size of the pore space. The porosity of foam metal often reaches over 90%, and it is a porous metal with a certain strength and rigidity. These metals have high porosity, with pore diameters reaching the millimeter level.

[0032] In this way, the porous foam metal has high porosity, good mechanical strength, and high temperature resistance and corrosion resistance, which makes the porous foam metal filter device 100 suitable for filtration needs in a variety of complex environments and helps to extend the service life of the porous foam metal filter device 100.

[0033] Furthermore, such as Figure 2 As shown, in the direction from the geometric center of the filter element 30 to the edge of the filter element 30, the distance between at least a portion of the filter element 30 and the inlet 21 tends to increase. Since the inlet 21 and the filter element 30 are arranged opposite each other, after the liquid enters the filtration space 11, it will contact the part of the filter element 30 that is closer to the inlet 21 first. At this time, the part of the filter element 30 that is closer to the inlet 21 will play a certain role in diverting the liquid, thereby slowing down the flow rate of the liquid and improving its filtration effect.

[0034] According to the embodiment of the present invention, the porous foam metal filter device 100 has a filter element 30 made of porous foam metal. Porous foam metal has high porosity, good mechanical strength, and high temperature resistance and corrosion resistance, which makes the porous foam metal filter device 100 suitable for filtration needs in a variety of complex environments and helps to extend the service life of the porous foam metal filter device 100.

[0035] In some embodiments, such as Figure 3 As shown, the porous foam metal includes a first part 31 and a second part 32. The first part 31 is disposed opposite to the water inlet 21. The second part 32 is connected to the inner wall of the filter tank 10 and is disposed around the first part 31. The minimum distance from the second part 32 to the water inlet 21 is greater than the maximum distance from the second part 32 to the water inlet 21.

[0036] It is understandable that after the liquid enters the filtration space 11, it will first come into contact with the first part 31. At this time, the first part 31 will play a certain role in diverting the liquid, thereby slowing down the flow rate of the liquid, so that the slowed liquid flows to the second part 32 for filtration, thereby improving its filtration effect.

[0037] In some embodiments, such as Figure 2 As shown, the first part 31 is disposed opposite to the inlet 21, and in the first direction, the thickness of the first part 31 is greater than the thickness of the second part 32.

[0038] Understandably, since the first part 31 is positioned opposite the inlet 21, the liquid entering the filtration space 11 through the inlet 21 will first impact the first part 31 before flowing to the second part 32. Therefore, setting the thickness of the first part 31 to be larger can enhance the structural strength of the first part 31, thereby enhancing its impact resistance and improving the structural stability of the porous foam metal.

[0039] In some embodiments, the outer surface of the first portion 31 facing the water inlet 21 is curved, and / or the outer surface of the second portion 32 facing the water inlet 21 is curved.

[0040] In this way, after the liquid enters the filtration space 11 through the inlet 21, the outer surface of the end of the first part 31 facing the inlet 21 can play a certain buffering role for the liquid, reducing the risk of the liquid directly impacting the first part 31.

[0041] In some embodiments, the outer surface of the end of the second part 32 facing the inlet 21 is curved. This allows the outer surface of the end of the second part 32 facing the inlet 21 to act as a buffer after the liquid enters the filtration space 11 through the inlet 21, reducing the risk of the liquid directly impacting the second part 32.

[0042] In some embodiments, the porosity of the porous foam metal gradually increases in the direction from the inlet 21 to the outlet 22.

[0043] In this way, the filtration precision of the porous foam metal gradually increases from the inlet 21 to the outlet 22. As a result, after the liquid enters the filtration space 11 from the inlet 21, a filtration process with gradually increasing filtration precision can be achieved, thereby enhancing its filtration effect.

[0044] In some embodiments, the porosity of the porous foam metal is 70%-90%.

[0045] For example, the porosity of porous foam metal is 70%, 82%, 85%, 85%, etc. When the porosity of porous foam metal is within the above range, it can ensure that porous foam metal has sufficient structural strength and sufficient filtration effect, so as to ensure the stability of porous foam metal in use.

[0046] In some embodiments, the pore size of the porous foam metal is 10 mm to 500 micrometers. For example, the pore size of the porous foam metal is 10 mm, 20 mm, 100 mm or 500 micrometers. That is, when the pore size of the porous foam metal meets the above range, the porous foam metal can have sufficient filtration effect while having sufficient structural strength, so as to ensure the stability of the porous foam metal in use.

[0047] Of course, the pore size of porous foam metal can also be other values, and the specific selection can be made according to the actual filtration needs. No limitation is made here.

[0048] In some embodiments, a plurality of filter elements 30 are provided, and the plurality of filter elements 30 are spaced apart along a first direction.

[0049] Therefore, after the liquid enters the filtration space 11 through the inlet 21, multiple filter elements 30 can be used to achieve multi-stage filtration, thereby enhancing its filtration effect.

[0050] In some embodiments, the plurality of filter elements 30 are all porous foam metals, and in the direction from the inlet 21 to the outlet 22, the porosity of the plurality of filter elements 30 gradually increases and the pore size gradually decreases.

[0051] In this way, the filtration precision of multiple filter elements 30 can be gradually increased. Thus, after the liquid enters the filtration space 11 from the inlet 21, multiple filter elements 30 can be used to achieve multi-stage filtration with gradually increasing filtration precision, thereby enhancing the filtration effect.

[0052] In some embodiments, such as Figure 2As shown, the porous foam metal filter device 100 further includes a first sealing ring 41, which is sealed between the end of the filter element 30 near the inlet 21 and the inner wall of the filter tank 10.

[0053] It is understood that the first sealing ring 41 can be a rubber sealing ring. The first sealing ring 41 can be sleeved on the end of the filter element 30 near the water inlet 21 and abut against the inner wall of the filter tank 10. This facilitates the sealing between the end of the filter element 30 near the water inlet 21 and the inner wall of the filter tank 10, thereby enhancing the sealing performance between the end of the filter element 30 near the water inlet 21 and the inner wall of the filter tank 10.

[0054] In some embodiments, such as Figure 2 As shown, the porous foam metal filter device 100 further includes a second sealing ring 42, which is sealed between the end of the filter element 30 near the outlet 22 and the inner wall of the filter tank 10.

[0055] It is understandable that the second sealing ring 42 can be a rubber sealing ring. The second sealing ring 42 can be sleeved on the end of the filter element 30 near the outlet 22 and abut against the inner wall of the filter tank 10. This facilitates the sealing between the end of the filter element 30 near the outlet 22 and the inner wall of the filter tank 10, thereby enhancing the sealing performance between the end of the filter element 30 near the outlet 22 and the inner wall of the filter tank 10.

[0056] In some embodiments, the filter tank 10 is provided with an observation window.

[0057] Understandably, an opening can be made in the filter tank 10, with a glass panel at the opening to form an observation window. This allows the user to observe the filtration process and the working status of the porous foam metal through the observation window, so that the porous foam metal can be replaced in time if it is found to be clogged and unable to filter.
