[0031] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0032] like Figure 1 and Figure 2 As shown, this disclosure provides a filter box 100, which may include a box body, two first filter plates 21 and a second filter plate 22.

[0033] The interior of the box is hollow, forming a storage space, and the top of the box is open.

[0034] The first filter plate 21 and the second filter plate 22 are disposed within the receiving space. The bottoms of the first filter plate 21 and the second filter plate 22 are attached to the inner bottom wall of the housing. The two first filter plates 21 are spaced apart. The second filter plate 22 is connected to the ends of the two first filter plates 21. The included angle between the second filter plate 22 and the first filter plate 21 is less than 180°. The second filter plate 22 is spaced apart from the inner side wall of the housing, that is, the second filter plate 22 is spaced apart from the inner side wall of the housing, and the second filter plate 22 does not directly contact the inner side wall of the housing. The ends of the two first filter plates 21 facing away from the second filter plate 22 are respectively connected to the inner side wall of the housing. The two first filter plates 21, the second filter plate 22, and the housing together form a filter chamber 23.

[0035] It should be noted that the above-mentioned "the second filter plate 22 is connected to the ends of the two first filter plates 21" means that the second filter plate 22 is connected to one of the opposite ends of the first filter plate 21.

[0036] The phrase "the bottom of the first filter plate 21 and the second filter plate 22 are attached to the inner bottom wall of the box" can mean that the bottom surfaces of the first filter plate 21 and the second filter plate 22 are completely attached to the inner bottom wall of the box, so as to improve the problem of mud and sand flowing from the gap between the first filter plate 21 and the inner bottom wall of the box, and from the gap between the second filter plate 22 and the inner bottom wall of the box to the outside of the filter chamber 23.

[0037] In addition, to further enhance the sealing of the filter chamber 23, this embodiment of the present disclosure may also provide a groove on the inner bottom wall of the housing, and embed the bottom of the first filter plate 21 and the second filter plate 22 into the groove. The bottom surfaces of the first filter plate 21 and the second filter plate 22 can be completely fitted with the bottom wall of the groove to improve the problem of silt flowing from the gap between the first filter plate 21 and the inner bottom wall of the housing, and from the gap between the second filter plate 22 and the inner bottom wall of the housing to the outside of the filter chamber 23.

[0038] This embodiment of the present disclosure provides two first filter plates 21 and a second filter plate 22 connected to the ends of the two first filter plates 21 within the housing. While the first filter plates 21, the second filter plate 22, and the housing form a filter chamber 23 to filter liquids containing sediment, the second filter plate 22 is spaced apart from the inner wall of the housing. This allows at least a portion of the filter surfaces of the two first filter plates 21 to be spaced apart from the inner wall of the housing. In this case, liquid can flow through the entire filter surface of the second filter plate 22 and the opposite sides of at least a portion of the filter surfaces of the two first filter plates 21, enabling sediment filtration through multiple filter surfaces. This increases the overall filter area of ​​the filter chamber 23, improving filtration efficiency and reducing the risk of filter surface clogging.

[0039] In this disclosure, after a liquid containing sediment is delivered into the filter chamber 23, the liquid can flow through the first filter plate 21 and the second filter plate 22 to the space outside the filter chamber 23 within the receiving space, while the sediment is blocked by the first filter plate 21 and the second filter plate 22 and remains in the filter chamber 23.

[0040] In some embodiments, the shape of the filter cavity 23 may be adapted to the shape of the receiving space.

[0041] For example, when the receiving space is square, the filter cavity 23 can also be square. However, it is not limited to this; the receiving space and the filter cavity 23 can also be other shapes besides square. For example, the receiving space can be pentagonal, hexagonal, etc., depending on the actual situation.

[0042] It should be understood that when the accommodating space is a polygon such as a quadrilateral, pentagon, or hexagon, one or more second filter plates 22 can be set between the two first filter plates 21 according to the actual shape of the accommodating space, so that the shape of the filter cavity 23 is adapted to the shape of the accommodating space.

[0043] Taking a pentagonal accommodating space as an example, two second filter plates 22 can be installed inside the filter box 100. The two second filter plates 22 are connected to each other and located between the two first filter plates 21. The end of the second filter plate 22 away from the other second filter plate 22 is connected to the end of the adjacent first filter plate 21. Thus, the two first filter plates 21, the two second filter plates 22 and the box body can form a pentagonal filter cavity 23 that matches the shape of the accommodating space.

[0044] This embodiment of the present disclosure adapts the shape of the filter cavity 23 to the shape of the accommodating space so that the filter cavity 23 formed by the first filter plate 21, the second filter plate 22 and the housing can make full use of the accommodating space.

[0045] like Figures 1 to 3 As shown, in some embodiments, the housing may include a feed side plate 11, a side baffle 12, and a bottom plate 13. The feed side plate 11 and the side baffle 12 are connected end to end and are arranged around the side periphery of the bottom plate 13. The bottom of the feed side plate 11 and the side baffle 12 are both attached to the top surface of the bottom plate 13, so that the feed side plate 11, the side baffle 12, and the bottom plate 13 can be arranged to form an accommodating space.

[0046] It should be noted that, in this disclosure, the inner bottom wall of the box refers to the top surface of the bottom plate 13, the feed side plate 11 and the side baffle 12 are both side walls of the box, and the inner side wall of the box refers to the side wall of the box that is close to the accommodating space.

[0047] For example, when the box is in the shape of Figure 1 When the shape is rectangular, the feed side plate 11 and the three side baffles 12 together form the side wall of the box.

[0048] In this embodiment, the ends of the two first filter plates 21 facing away from the second filter plate 22 can be connected to the inner wall of the feed side plate 11. By spacing the first filter plates 21 from the side baffle 12, liquid can flow through the entire filter surface of the first filter plate 21 and the entire filter surface of the second filter plate 22 that form the filter cavity 23. This increases the overall filter area of ​​the filter cavity 23, thereby improving filtration efficiency and reducing the risk of filter surface clogging. For details, please refer to... Figure 1 and Figure 2 As shown.

[0049] In some embodiments, the distance between the first filter plate 21 and the side baffle 12, and the distance between the second filter plate 22 and the side baffle 12, can be no less than 150mm. This ensures that there is enough space on both sides of the filter surfaces of the first filter plate 21 and the second filter plate 22 to facilitate liquid flow, while also reserving space for assembly between the first filter plate 21, the second filter plate 22 and the housing.

[0050] In some embodiments, the first filter plate 21 and the second filter plate 22 can be detachably connected to the housing. By separating the first filter plate 21 and the second filter plate 22 from the housing, it is easy to clean, maintain and replace the first filter plate 21 and the second filter plate 22, so as to improve the problem of low filtration efficiency caused by the clogging of the first filter plate 21 and the second filter plate 22. At the same time, it can also improve the problem of a large amount of mud and sand flowing outside the filter chamber 23 due to the damage of the first filter plate 21 and the second filter plate 22, resulting in poor filtration effect.

[0051] For example, such as Figures 4 to 7 As shown, two first connecting plates 14 can be installed on the inner sidewall of the housing, each corresponding to a first filter plate 21. Two corner posts 3 can be installed within the accommodating space, with their bottom surfaces connected to the inner bottom wall of the housing. Each corner post 3 can include two second connecting plates 31 spaced apart circumferentially. First connecting pieces 41 can be installed at opposite ends of the first filter plate 21. The first connecting piece 41 at the end of the first filter plate 21 furthest from the second filter plate 22 partially overlaps with the first connecting plate 14, and a bolt connection can be achieved at the overlapping portion of the first filter plate 21 and the first connecting plate 14. The first connecting piece 41 at the end of the first filter plate 21 closest to the second filter plate 22 partially overlaps with the adjacent second connecting plate 31, and a bolt connection can be achieved at the overlapping portion of the first filter plate 21 and the second connecting plate 31. Second connecting pieces 42 can be installed at opposite ends of the second filter plate 22. The second connecting pieces 42 partially overlap with the adjacent second connecting plate 31, and a bolt connection can be achieved at the overlapping portion of the second filter plate 22 and the second connecting plate 31.

[0052] Specifically, the first connecting plate 14 can protrude away from the inner wall of the housing, and the height of the first connecting plate 14 in the vertical Z direction can be equal to the height of the corresponding first filter plate 21. The first connecting plate 14 can be provided with multiple through holes arranged at intervals along the vertical Z direction, and the multiple through holes on the first connecting plate 14 can be evenly spaced.

[0053] Corner post 3 can be detachably connected to the inner bottom wall of the enclosure. For example... Figure 5 As shown, the two second connecting plates 31 on the corner post 3 protrude in a direction away from the corner post 3 and are arranged at intervals on the side periphery of the corner post 3. The height of the second connecting plates 31 in the vertical Z direction can be equal to the height of the corresponding connected first filter plate 21 or second filter plate 22. Multiple through holes can be provided on the second connecting plates 31 at intervals along the vertical Z direction, and the multiple through holes on the first connecting plate 14 can be evenly spaced.

[0054] The vertical Z-height of the first connecting piece 41 can be equal to the vertical Z-height of the first filter plate 21, and the opposite ends of the first connecting piece 41 in the vertical Z-direction can be flush with the opposite ends of the first filter plate 21 in the vertical Z-direction. Therefore, when the first connecting piece 41 is connected to the first connecting plate 14 or the second connecting plate 31, the gap between the first filter plate 21 and the inner wall of the housing can be sealed by the first connecting plate 14 and the first connecting piece 41, and the gap between the first filter plate 21 and the corner post 3 can be sealed by the second connecting plate 31 and the first connecting piece 41. This improves the problem of sediment leaving the filter chamber 23 through the gap between the first filter plate 21 and the housing, and through the gap between the first filter plate 21 and the corner post 3, thereby improving the filtration effect of the filter box 100. Multiple through holes arranged at intervals along the vertical Z-direction can be provided on the first connecting piece 41.

[0055] During the process of connecting the first connecting piece 41 to the first connecting plate 14, the first connecting piece 41 and the first connecting plate 14 overlap at least partially, and the through holes on the first connecting plate 14 and the through holes on the first connecting piece 41 correspond one-to-one in the overlapping area. The bolt can pass through the through holes on the first connecting plate 14 and the through holes on the first connecting piece 41 to achieve a detachable connection between the first connecting piece 41 and the first connecting plate 14, thereby achieving a detachable connection between the first filter plate 21 and the housing.

[0056] Similarly, during the process of connecting the first connecting piece 41 to the second connecting plate 31 on the corner post 3, the first connecting piece 41 and the second connecting plate 31 at least partially overlap, and the through holes on the second connecting plate 31 correspond one-to-one with the through holes on the first connecting piece 41 in the overlapping area. Bolts can pass through the through holes on the second connecting plate 31 and the first connecting piece 41 to achieve a detachable connection between the first connecting piece 41 and the second connecting plate 31, thereby achieving a detachable connection between the first filter plate 21 and the corner post 3. For details, please refer to... Figure 5 As shown.

[0057] The vertical Z-height of the second connecting piece 42 can be equal to the vertical Z-height of the second filter plate 22, and the opposite ends of the second connecting piece 42 in the vertical Z-direction can be flush with the opposite ends of the second filter plate 22 in the vertical Z-direction. Therefore, when the second connecting piece 42 is connected to the second connecting plate 31, the gap between the second filter plate 22 and the corner post 3 can be sealed by the second connecting plate 31 and the second connecting piece 42, thereby improving the problem of sediment leaving the filter chamber 23 through the gap between the second filter plate 22 and the corner post 3, and thus enhancing the filtration effect of the filter box 100. Multiple through holes arranged at vertical Z-intervals can be provided on the second connecting piece 42.

[0058] During the connection of the second connecting piece 42 and the second connecting plate 31, the second connecting piece 42 and the second connecting plate 31 at least partially overlap, and the through holes on the second connecting plate 31 and the through holes on the second connecting piece 42 correspond one-to-one in the overlapping area. Bolts can pass through the through holes on the second connecting plate 31 and the through holes on the second connecting piece 42 to achieve a detachable connection between the second connecting piece 42 and the second connecting plate 31, thereby achieving a detachable connection between the second filter plate 22 and the housing. For details, please refer to... Figure 5 As shown.

[0059] Taking a square-shaped space and a square-shaped filter chamber 23 as an example, in this case, if Figure 1 As shown, one of the four side walls of the square box can be used as the feed side plate 11, and the other three side walls can be used as side baffles 12. Two first connecting plates 14 can be installed on the feed side plate 11, two first filter plates 21 are installed perpendicular to the feed side plate 11, and a second filter plate 22 is parallel to the feed side plate 11. An angle post 3 is installed between the first filter plate 21 and the second filter plate 22, such as... Figure 5 As shown, the corner post 3 can be a hollow rectangular column. The height of the corner post 3, the height of the first filter plate 21, and the height of the second filter plate 22 can be equal. For example, the height of the corner post 3, the first filter plate 21, and the second filter plate 22 can be equal to the height of the housing. A second connecting plate 31 can be respectively provided on the two sides of the corner post 3 facing the first filter plate 21 and the second filter plate 22 for connecting to the first connecting piece 41 and the second connecting piece 42, respectively.

[0060] Both the first connecting plate 14 and the second connecting plate 31 in this disclosure can be L-shaped. One side of the L-shaped first connecting plate 14 can be fitted against the inner wall of the housing, while the other side can be perpendicular to the corresponding inner wall of the housing and protrude away from the inner wall of the housing for bolt connection with the corresponding first connecting piece 41. One side of the L-shaped second connecting plate 31 can be fitted against the surface of the corner post 3, while the other side can be perpendicular to the corresponding surface of the corner post 3 and protrude away from the corner post 3 for bolt connection with the corresponding first connecting piece 41 or second connecting piece 42. For details, please refer to [reference needed]. Figure 5 As shown.

[0061] like Figures 6 to 8 As shown, in some embodiments, a third connecting piece 43 may be provided at the bottom of the first filter plate 21 and the second filter plate 22. The top of the third connecting piece 43 is connected to the bottom of the corresponding first filter plate 21 or the bottom of the second filter plate 22, and the third connecting piece 43 extends along the height direction of the housing. The third connecting piece 43 may have a plurality of evenly spaced through holes arranged in its length direction. A third connecting plate 15 corresponding to the third connecting piece 43 may be provided on the inner bottom wall of the housing, and a plurality of evenly spaced through holes may be provided on the third connecting plate 15.

[0062] When the third connecting piece 43 is connected to the third connecting plate 15, the third connecting piece 43 and the corresponding third connecting plate 15 partially overlap, and the through holes on the third connecting piece 43 and the through holes on the third connecting plate 15 correspond one-to-one in the overlapping area. The bolt can pass through the through holes on the third connecting plate 15 and the through holes on the third connecting piece 43 to achieve a detachable connection between the third connecting piece 43 and the third connecting plate 15, thereby achieving a detachable connection between the first filter plate 21 and the housing, and a detachable connection between the second filter plate 22 and the housing.

[0063] Furthermore, such as Figure 8 As shown, a support plate 44 can be connected to the side of the third connecting piece 43 near the bottom wall of the box. The side of the support plate 44 away from the third connecting piece 43 is in contact with the bottom wall of the box. The orthographic projection of the third connecting piece 43 on the bottom wall of the box is located within the orthographic projection of the support plate 44 on the bottom wall of the box.

[0064] By providing a support plate 44, the contact surface between the first filter plate 21 and the second filter plate 22 and the bottom wall of the housing can be increased. This not only strengthens the connection stability between the first filter plate 21 and the second filter plate 22 and the bottom wall of the housing, but also enhances the sealing of the gaps between the first filter plate 21 and the bottom wall of the housing, as well as the gaps between the second filter plate 22 and the bottom wall of the housing. This reduces the possibility of sediment flowing from the gaps between the first filter plate 21 or the second filter plate 22 and the housing to the outside of the filter chamber 23, thereby improving the filtration efficiency of the filter box 100.

[0065] It should be noted that the support plate 44 in this embodiment can be integrally formed with the third connecting piece 43.

[0066] like Figure 3 and Figure 5 As shown, in some embodiments, a reinforcing member 32 can be provided in the accommodating space. The bottom surface of the reinforcing member 32 is connected to the inner bottom wall of the box, and one side of the reinforcing member 32 abuts against the outer side of the corner post 3. By abutting the reinforcing member 32 against the inner bottom wall of the box and the corner post 3, the support of the corner post 3 can be strengthened, and the stability of the corner post 3 on the box can be improved.

[0067] For example, in this embodiment of the present disclosure, the reinforcing member 32 can be a right-angled triangular plate structure. One right-angled side of the reinforcing member 32 is connected to the inner bottom wall of the box, and the other right-angled side of the reinforcing member 32 abuts against the outer surface of the corner post 3. The reinforcing member 32 can be welded to the corner post 3. However, it is not limited to this. The reinforcing member 32 in this embodiment of the present disclosure can also be other structures besides the right-angled triangular plate structure. The specific design can be determined according to the actual situation.

[0068] like Figure 5As shown, in some embodiments, the filter box 100 may include a gasket 33. The gasket 33 may be disposed between the first connecting piece 41 and the first connecting plate 14 to enhance the stability of the connection between the first connecting plate 14 and the first connecting piece 41.

[0069] However, this is not the only option. In this embodiment, the gasket 33 may also be disposed between the first connecting piece 41 and the second connecting plate 31, and / or between the second connecting piece 42 and the second connecting plate 31, and / or between the third connecting piece 43 and the third connecting plate 15. The specific arrangement can be determined according to the actual situation.

[0070] For example, the material used to prepare gasket 33 may include ethylene propylene diene monomer (EPDM) rubber, but is not limited to this. Other materials with excellent corrosion resistance and elasticity may also be used as the material used to prepare gasket 33 in the embodiments of this disclosure.

[0071] like Figure 6 , Figure 9 and Figure 10 As shown, in some embodiments, both the first filter plate 21 and the second filter plate 22 may include a filter screen 24 and a fixing frame 25. The filter screen 24 is disposed in the hollow area inside the fixing frame 25, and its side periphery is connected to the fixing frame 25.

[0072] For example, the filter screen 24 can be a 50-mesh stainless steel filter screen 24, and the fixing frame 25 is arranged around the side perimeter of the filter screen 24 to strengthen the structural strength of the first filter plate 21 and the second filter plate 22 and reduce the risk of deformation of the first filter plate 21 and the second filter plate 22 under pressure. The fixing frame 25 can be a square tube with a hollow interior to reduce the weight of the first filter plate 21 and the second filter plate 22 and reduce transportation costs.

[0073] In some embodiments, a water inlet pipe 5 is provided in the accommodating space. The water inlet pipe 5 is connected to the inner side wall of the box. The water inlet end of the water inlet pipe 5 is located at the top of the box, and the water outlet end of the water inlet pipe 5 is located in the filter chamber. Liquid containing mud and sand can be input into the filter chamber 23 for filtration through the water inlet pipe 5.

[0074] For example, a connector 51 can be provided between the water inlet pipe 5 and the inner wall of the box. The two ends of the connector 51 are respectively connected to the water inlet pipe 5 and the inner wall of the box to fix the water inlet pipe 5 inside the box.

[0075] Multiple connectors 51 can be provided between the water inlet pipe 5 and the inner side wall of the tank, and the multiple connectors 51 can be arranged at even intervals along the vertical direction.

[0076] The inlet end of the water inlet pipe 5 can be flush with the top surface of the tank, or the inlet end of the water inlet pipe 5 can be slightly lower than the bottom surface of the tank, so as to obtain liquid containing mud and sand from the outside and transport the liquid containing mud and sand into the tank.

[0077] The outlet end of the inlet pipe 5 can be lower than the inlet end of the inlet pipe 5, which can improve the problem of liquid containing mud and sand splashing when entering the filter chamber 23 through the inlet pipe 5, thereby improving the filtration effect of the filter box 100.

[0078] For example, the water inlet pipe 5 can be installed on the feed side plate 11, but it is not limited to this. The water inlet pipe 5 can also be installed on the side baffle 12. The specific installation can be set according to the actual situation.

[0079] In this embodiment, the inlet pipe 5 can be connected to the inlet end of the water inlet pipe 5 using a FIG1502 connector, facilitating quick installation and removal between the inlet pipe 5 and the housing. During transport of the filter box 100, the inlet pipe 5 can be removed from the housing to address the issue of the filter box 100 exceeding the external dimensions of a standard container. When using the filter box 100 for sediment filtration, the inlet pipe 5 can be reinstalled on the housing.

[0080] In some embodiments, a mud discharge pipe 6 may be provided on the side wall of the housing. The mud discharge pipe 6 penetrates the side wall of the housing and communicates with the filter chamber 23. The mud discharge pipe 6 may be located on the side wall of the housing near the bottom wall of the housing, so as to discharge the mud and sand deposited on the bottom wall of the housing out of the filter chamber 23, thereby improving the problem of mud and sand clogging the first filter plate 21 and the second filter plate 22, and thus improving the filtration efficiency of the filter box 100.

[0081] The mud discharge pipe 6 can be located on the side of the water inlet end of the water inlet pipe 5 near the bottom wall of the tank.

[0082] The sludge discharge pipe 6 and the water inlet pipe 5 can be located on the same side wall of the housing. For example, both the sludge discharge pipe 6 and the water inlet pipe 5 can be installed on the feed side plate 11. The inlet end of the sludge discharge pipe 6 can be adjacent to the outlet end of the water inlet pipe 5, so that the sludge flowing out of the outlet end of the water inlet pipe 5 can be deposited at the position adjacent to the sludge discharge pipe 6. This allows the sludge to flow quickly into the sludge discharge pipe 6 and be quickly discharged to the outside of the filter chamber 23 through the sludge discharge pipe 6.

[0083] For example, in this embodiment of the present disclosure, the sludge discharge pipe 6 can be connected to the water inlet end of the sludge discharge pipe 6 using a threaded 4” FIG206+FIG207 connector, so as to facilitate quick loading and unloading between the sludge discharge pipe 6 and the housing. During transportation of the filter box 100, the sludge discharge pipe 6 can be removed from the housing to improve the problem of the filter box 100 exceeding the external dimensions of the standard container. When using the filter box 100 for sludge filtration, the sludge discharge pipe 6 can be reinstalled on the housing.

[0084] In some embodiments, a drain pipe 7 may be provided on the side wall of the housing. The drain pipe 7 penetrates the side wall of the housing and communicates with the space outside the filter chamber 23, so as to discharge the liquid filtered by the filter chamber 23 into the space.

[0085] In this embodiment, the drain pipe 7 and the inlet pipe 5 can be located on opposite sides of the housing. For example, when the inlet pipe 5 is installed on the feed side plate 11, the drain pipe 7 can be installed on the side baffle 12, with the drain pipe 7 and the inlet pipe 5 located on opposite sides of the housing. The inlet end of the drain pipe 7 can be located on the side wall of the housing away from the bottom wall inside the housing. When some sediment flows into the space outside the filter chamber 23, the sediment is deposited on the bottom wall of the housing under gravity, thereby reducing the amount of sediment in the liquid flowing out of the space through the inlet end of the drain pipe 7, thus improving the purity of the obtained liquid.

[0086] For example, in this embodiment of the present disclosure, the drain pipe 7 can be connected to the inlet end of the drain pipe 7 using a threaded 4” FIG206+FIG207 connector, so as to facilitate quick loading and unloading between the drain pipe 7 and the housing. During transportation of the filter box 100, the drain pipe 7 can be removed from the housing to improve the problem of the filter box 100 exceeding the external dimensions of the standard container. When using the filter box 100 for sediment filtration, the drain pipe 7 can be reinstalled on the housing.

[0087] In some embodiments, a reinforcing plate 8 may also be provided within the accommodating space. The opposite ends of the reinforcing plate 8 may be connected to the inner sidewall of the box to enhance the overall structural strength of the box.

[0088] For example, such as Figure 2 As shown, when the accommodating space is square, a reinforcing plate 8 can be installed at each of the four top corners of the square box, and the opposite ends of the reinforcing plate 8 are connected to the adjacent side walls of the box.

[0089] In some embodiments, a lifting lug 9 may be provided on the side of the reinforcing plate 8 facing away from the bottom wall of the housing, so as to facilitate the hoisting of the filter box 100 by means of the lifting lug 9.
