In the filter provided by the invention, when the filter is used for filtering, firstly, liquid is added into the body 1 through the charging pipe 4, and the space between the body 1 and the cover body 2 is gradually filled, wherein when the liquid passes through the connecting plate 5, the liquid can only pass through the connecting cylinder 6, the filter element 7 and the filtering holes in sequence and then reach the space above the connecting plate 5 because the connecting plate 5 is solid, and meanwhile, the liquid is filtered by the filter element 7 in the process.

When the filter element 7 needs to be cleaned along with the progress of filtration, firstly, the cover body 2 is opened or separated from the body 1 (the conventional means is possibly used for separation or opening), then the filter element 7 is taken out from the connecting cylinder 6 for cleaning, the filter element 7 is put into the connecting cylinder 6 from top to bottom after the cleaning is finished until the top of the filter element 7 is equal to the top of the connecting cylinder 6, part of the height of the top of the filter element 7 is attached to the inner wall of the connecting cylinder 6, and then the filter element 7 is fixed through a fixing mechanism (the conventional straight cylinder type filter element 7 structure also has a corresponding fixing structure for preventing the filter element 7 from being separated from the connecting cylinder 6, so that the shape of the filter element 7 and the shape of the connecting cylinder 6 are changed by the change of the core, and the filter element 7 and the connecting cylinder 6 are convenient to combine); since the filter element 7 and the connecting cylinder 6 are both of a conical structure with a large upper part and a small lower part, the filter element 7 can be more convenient when being combined into the connecting cylinder 6.

Furthermore, since the filter element 7 is conical, the conical filter element can have a larger surface area than the straight filter element 7 with the same height, so that more liquid can be filtered at the same time, and the filtering efficiency is higher.

Meanwhile, since the minimum cross-sectional area of the filter element 7 is smaller than the minimum cross-sectional area of the connecting cylinder 6, and the depth of the filter element 7 is smaller than the depth of the connecting cylinder 6, when the filter element 7 is connected into the connecting cylinder 6, a certain gap exists between the outer surface of the filter element 7 and the inner surface of the connecting cylinder 6, so that liquid can act on the whole outer surface of the filter element 7 after passing through the connecting cylinder 6, namely, the surface of the filter element 7 is prevented from being covered by the solid structure of the connecting cylinder 6 and can not be filtered normally, and the whole filtering speed and quality are ensured.

When the cleaned filter element 7 is installed in the connecting cylinder 6, firstly, the top of the filter element 7 is flush with the top of the connecting cylinder 6, and at the moment, the top of the filter element 7 cannot continue to move downwards under the limiting action of the inner wall of the connecting cylinder 6, and only can horizontally rotate. The filter element 7 is horizontally rotated through the connecting rod 9 until two ends of the connecting rod 9 are respectively clamped into clamping spaces between the two fixing bodies 11 and the connecting plate 5 (the directions of the two fixing bodies 11 are opposite), then the connecting rod 9 is rotated, the connecting rod 9 moves under the action of threads of the connecting rod 8 to drive the two connecting pieces 10 to move towards the two fixing grooves 12 respectively (in the figure 3, the two connecting pieces 10 move leftwards, the fixing grooves 12 on the connecting pieces 8 on two sides face rightwards, and the openings of the two connecting pieces 10 face leftwards at the same time), until the two connecting pieces 10 are clamped into the fixing grooves 12, and the positioning of the filter element 7 is completed. At this time, the filter element 7 is limited by the inner wall of the connecting cylinder 6 and the fixing body 11 in the vertical direction, and is limited by the inner wall of the fixing groove 12 in the horizontal direction so that the filter element 7 cannot rotate, so that the fixing of the filter element 7 is completed, and the fixing is simple and convenient. When the filter element 7 is taken out, only the connecting rod 9 is required to be reversely rotated, after the connecting piece 10 is separated from the fixing groove 12, the connecting rod 9 is horizontally rotated again, the connecting rod 9 can be separated from the clamping space between the fixing body 11 and the connecting plate 5, and then the filter element 7 is lifted upwards. The hexagonal prism-shaped rotating portion 13 makes the rotating operation more convenient when the connecting rod 9 is rotated.

When separating the cover 2 from the body 1, the sealing nut 18 is first turned and the sealing nut 18 is disengaged from the sealing rod 16, and then the cover 2 is lifted upward until the sealing groove 17 is higher than the sealing rod 16, and then the cover 2 is removed by horizontally moving the cover 2. Or the sealing screw cap 18 is rotated so that the sealing screw cap 18 reaches a higher height, the sealing rod 16 is rotated downwards, so that the sealing rod 16 and the sealing screw cap 18 are both rotated to the side of the sealing groove 17, and then the cover body 2 can be lifted and separated from the body 1 directly upwards. When the cover body 2 is connected with the body 1, the cover body 2 firstly abuts against the sealing gasket 15 in the sealing groove 14, the cover body 2 continues to move downwards under the drive of the sealing nut 18, the sealing gasket 15 is pressed to deform until the cover body 2 abuts against the body 1 finally, and the cover body 2 and the sealing gasket are in sealing connection.

When the liquid is first introduced into the body 1, the first valve 21 is opened and the second valve 22 is closed, and at this time, the air is sequentially discharged to the outside through the discharge pipe 3 and the discharge pipe 19. When the liquid is nearly full of the body 1, the first valve 21 is closed and the second valve 22 is opened, and the filtered liquid is discharged from the liquid discharge pipe 20 and collected, so that the air quantity in a container or equipment for collecting the liquid can be reduced, and the subsequent processing is facilitated. When clearing up filter core 7, only need close third valve 23 can, the liquid in the body 1 can not follow charging tube 4 and flow backwards out this moment yet, and the practicality is strong.

It should be noted that, in the present description, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different manner from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.

The above description is only illustrative of the preferred embodiments of the present invention and is not intended to limit the scope of the present invention, and any alterations and modifications made by those skilled in the art based on the above disclosure shall fall within the scope of the appended claims.
