The cover plate 1 and the connecting plate 2 are connected by the swing bolt 3 and the nut 4. The swing bolt 3 passes through the U-shaped notch 5, and one end of the swing bolt 3 is connected to the nut 4.

[0035] The utility model discloses a mud filter that can be quickly disassembled and cleaned, wherein the connection mode between the cover plate 1 and the connecting plate 2 of the filter is changed into a disassembly connection with multi-point nuts 4 and movable bolts 3. On the one hand, the disassembly connection mode with multi-point nuts 4 and movable bolts 3 can make the cover plate 1 and the connecting plate 2 subjected to multi-directional compression and sealing, thereby better preventing liquid leakage. On the other hand, when disassembling the cover plate 1, the cover plate 1 can be quickly opened by rotating the movable bolts 3 along the U-shaped notch 5 after the nut 4 is rotated to loosen it, thereby making the operation more convenient.

[0036] As an implementation method, Figure 7 and Figure 8 As shown, the cover plate 1 and the connecting plate 2 are circular in shape. More specifically, the cover plate 1 is a circular solid plate, and the connecting plate 2 is a circular hollow plate.

[0037] As an implementation method, Figure 7 and Figure 8 As shown, the U-shaped notch 5 is located at the edges of the cover plate 1 and the connecting plate 2.

[0038] As an implementation method, Figure 7 and Figure 8As shown, there are a plurality of U-shaped notches 5 , which are evenly distributed around the edges of the cover plate 1 and the connecting plate 2 .

[0039] As a specific implementation method, Figure 7 and Figure 8 As shown, there are 6 U-shaped notches 5 on the cover plate 1 and 6 U-shaped notches 5 on the connecting plate 2 . The 6 U-shaped notches 5 on the cover plate 1 correspond to the 6 U-shaped notches 5 on the connecting plate 2 one by one.

[0040] As a specific implementation manner, there are 8 U-shaped notches 5 on the cover plate 1 and 8 U-shaped notches 5 on the connecting plate 2 . The 8 U-shaped notches 5 on the cover plate 1 correspond one to one with the 8 U-shaped notches 5 on the connecting plate 2 .

[0041] As a specific implementation manner, there are five U-shaped notches 5 on the cover plate 1 and five U-shaped notches 5 on the connecting plate 2 . The five U-shaped notches 5 on the cover plate 1 correspond one to one to the five U-shaped notches 5 on the connecting plate 2 .

[0042] That is to say, the utility model does not impose specific restrictions on the number of U-shaped notches 5 on the cover plate 1 and the connecting plate 2. The number of U-shaped notches 5 on the cover plate 1 and the connecting plate 2 can be selectively set according to the actual situation such as the shape, size, material factors, etc. of the cover plate 1 and the connecting plate 2. Any number of U-shaped notches 5 that can realize the connection mode of the cover plate 1 and the connecting plate 2 of the filter being changed to a multi-point disassembly connection by cooperating with the nut 4 and the movable bolt 3 is within the protection scope of the utility model.

[0043] As an implementation method, Figure 7 and Figure 8 As shown, the U-shaped notches 5 on the cover plate 1 and the U-shaped notches 5 on the connecting plate 2 are the same in size, shape and number.

[0044] like Figure 2-Figure 6 As shown, there are a plurality of pivot bolts 3 , the number of which is the same as the number of the U-shaped notches 5 on the cover plate 1 , and the number of the nuts 4 is the same as the number of the pivot bolts 3 .

[0045] Specifically, the nut 4 may be a butterfly nut, which makes it more convenient for the staff to rotate the nut 4.

[0046] The swing bolt 3 includes a swing bolt 3 body, one side or one end of the swing bolt 3 body is provided with a swing bolt 3 head, the swing bolt 3 head is spherical and has a through hole, and the other end or one side of the swing bolt 3 body is provided with a thread on the surface, and the thread is matched with the nut 4. The swing bolt 3 is an existing mature component, and the utility model does not make too many redundant descriptions about the swing bolt 3.

[0047] like Figure 2 , Figure 3 and Figure 4 As shown, the filter also includes a filter standpipe 6, one end of which is connected to the connecting plate 2, and a plurality of ear seat groups 7 are provided on the side of one end of the filter standpipe 6. The number of the ear seat groups 7 is the same as the number of the movable bolts 3, and the position of the ear seat group 7 corresponds to the position of the U-shaped notch 5. The other end of the movable bolt 3 is movably connected to the ear seat group 7.

[0048] like Figure 2 As shown, the ear seat group 7 is located at the upper side of the filter standpipe 6, and the ear seat group 7 is used to connect with the head of the swing bolt 3, such as Fig.11 and Fig.12 As shown, an ear seat group 7 includes a first ear seat 17, a second ear seat 18 and a pin 19. An axial hole is provided on the first ear seat 17. The first ear seat 17 and the second ear seat 18 have the same structure. There is a certain gap between the first ear seat 17 and the second ear seat 18 for accommodating the head of the swing bolt 3. The pin 19 passes through the first ear seat 17, the head of the swing bolt 3 and the second ear seat 18, thereby connecting the ear seat group 7 with the head of the swing bolt 3. The swing bolt 3 can rotate in a direction perpendicular to the pin 19 with the pin 19 as the axis and the head of the swing bolt 3 as the center.

[0049] like Figure 2 , Fig.11 As shown, the number of ear seat groups 7, the number of hinge bolts 3, the number of nuts 4, the number of U-shaped notches 5 on the cover plate 1, and the number of U-shaped notches 5 on the connecting plate 2 are all the same, that is, the ear seat groups 7, the hinge bolts 3, the nuts 4, the U-shaped notches 5 on the cover plate 1, and the U-shaped notches 5 on the connecting plate 2 are all in a one-to-one correspondence.

[0050] The head of the swing bolt 3 is movably connected to the ear seat group 7 located on the side of the filter standpipe 6. The rod body of the swing bolt 3 passes through the connecting plate 2 and the cover plate 1 from bottom to top in sequence through the U-shaped notch 5. The other end of the swing bolt 3 opposite to the head of the swing bolt 3 is exposed above the cover plate 1 and is connected to the nut 4 through threaded cooperation. Tightening the nut 4 realizes a compression seal between the cover plate 1 and the connecting plate 2.

[0051] When the cover plate 1 needs to be opened, the nut 4 is rotated to loosen it, and then the movable bolt 3 is rotated along the U-shaped notch 5 so that the movable bolt 3 is withdrawn from the U-shaped notch 5, and the cover plate 1 can be quickly opened.

[0052] like Figure 2 and Figure 4 As shown, a first connecting pipe 8 and a second connecting pipe 9 are provided on both sides of the filter standpipe 6 . The first connecting pipe 8 and the second connecting pipe 9 are arranged opposite to each other. The first connecting pipe 8 is connected to a first flange 10 , and the second connecting pipe 9 is connected to a second flange 11 .

[0053] The first flange 10 and the second flange 11 are used to connect the external pipeline. The liquid in the external pipeline enters the filter standpipe 6 through the first connecting pipe 8 (or the second connecting pipe 9), is filtered by the filter plate 12 in the filter standpipe 6, and then flows out from the second connecting pipe 9 (or the first connecting pipe 8) to the external pipeline, and impurities such as mud and sand are trapped in the filter standpipe 6.

[0054] As an implementation manner, the first connecting pipe 8 and the second connecting pipe 9 have the same diameter.

[0055] As an implementation manner, the calibers of the first connecting tube 8 and the second connecting tube 9 may be different, such as the caliber of the first connecting tube 8 is larger than the caliber of the second connecting tube 9 or the caliber of the second connecting tube 9 is larger than the caliber of the first connecting tube 8 .

[0056] like Fig. 9 and Fig.10 As shown, a filter plate 12 is provided in the filter standpipe 6 , and the first connecting pipe 8 and the second connecting pipe 9 are respectively located on both sides of the filter plate 12 .

[0057] Specifically, the width of the filter plate 12 is the same as the diameter of the filter standpipe 6, and the height of the filter plate 12 is the same as the height of the filter standpipe 6, so that the liquid flowing into the filter standpipe 6 from the first connecting pipe 8 (or the second connecting pipe 9) must be filtered by the filter plate 12 before flowing out from the second connecting pipe 9 (or the first connecting pipe 8).

[0058] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the filter standpipe 6 is provided with a high-pressure cleaning interface 13 and a sewage outlet 14 , which are arranged on both sides of the filter standpipe 6 relatively, and are located at the bottom of the side of the filter standpipe 6 .

[0059] As an embodiment, the sewage outlet 14 is located at a position of the filter standpipe 6 as close to the bottom as possible.

[0060] As an implementation manner, the height of the high-pressure cleaning interface 13 is higher than the height of the sewage outlet 14 .

[0061] The high-pressure cleaning interface 13 is used to connect a high-pressure cleaning device, such as a high-pressure water gun or a water pipe of a high-pressure water pump. After opening the cover plate 1, the internal condition of the filter standpipe 6 can be checked. If high-pressure cleaning is required, the ball valve of the sewage outlet 14 is opened after the cover plate 1 is pressed tightly, so that the quick connector of the high-pressure cleaning interface 13 is connected to the high-pressure pipeline, thereby performing high-pressure cleaning.

[0062] like Figure 2 , Figure 3 and Figure 4As shown, a purge line interface 15 is provided on the filter standpipe 6 , and the purge line interface 15 is located above the side of the filter standpipe 6 .

[0063] The purge line interface 15 is used to connect an air source, such as an air pipe of an air gun or an air pump. After opening the cover plate 1, the internal condition of the filter standpipe 6 can be checked. If purge is required, the ball valve of the drain port 14 is opened after the cover plate 1 is pressed tightly, so that the purge line interface 15 is connected to an air source for purge, and the mud is discharged from the drain port 14.

[0064] As an embodiment, the purge line interface 15 is located above the side of the filter standpipe 6, and the axis of the purge line interface 15 is at a certain angle to the filter plate 12 in the filter standpipe 6, such as 90 degrees or 60 degrees to the filter plate 12 in the filter standpipe 6, to facilitate purge.

[0065] Furthermore, a rubber plate 16 is provided between the cover plate 1 and the connecting plate 2 , and the shape of the rubber plate 16 is the same as that of the cover plate 1 .

[0066] The shape of the rubber plate 16 is the same as that of the cover plate 1, which is also circular. U-shaped notches 5 that are the same as and corresponding to those on the cover plate 1 and the connecting plate 2 are provided around the edges of the rubber plate 16. The size of the rubber plate 16 can be the same as that of the cover plate 1 or slightly smaller than that of the cover plate 1.

[0067] As an implementation method, Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, a handle 20 is provided on the top of the cover plate 1 to facilitate taking and placing the cover plate 1.

[0068] The utility model redesigns the mud filter according to the requirements of on-site use, and replaces the rotary screw disassembly of the cover plate with multi-point butterfly nuts and live bolts. It can be quickly disassembled and can be sealed in multiple directions to better avoid leakage. The original O-type rubber ring is replaced with a rubber plate to further enhance the sealing performance, avoid the need for frequent cleaning after on-site leakage, and reduce the cost of later maintenance. On this basis, the air pipeline flushing function and high-pressure cleaning function are added, which can quickly and effectively clean up deposits and blockages and avoid cumbersome operations during cleaning.

[0069] The utility model adopts an easy-to-implement method to redesign the mud filter to address the problems of easy leakage, difficult disassembly, ineffective sealing, and inability to quickly clean. It avoids frequent cleaning and frequent failure of the sealing surface caused by leakage of the mud filter, and adds flushing lines and cleaning lines on this basis to achieve the function of rapid cleaning, so that the mud filter can quickly clean the filter screen and sediment, effectively saving maintenance costs and facilitating on-site maintenance and later care.
