The inner filter element 22 can also be connected to the base 1 in the following manner: the outer diameter of the inner filter member 22 is larger than the diameter of the central opening of the base 1, so that the end of the inner filter member 22 is directly welded to the base 1 to be connected after the center axis of the inner filter member 22 is aligned with the center of the central opening of the base 1.

However, without being limited thereto, the inner and outer filter members may also be cylinders with one end open and the other end closed, the open ends of the inner and outer filter members being connected, e.g. detachably connected, to the base. At this moment, after the material flows in from the central trompil of base, can not follow the other end direct outflow of drum, but flow out again after filtering from the lateral wall of drum, when needs clearance filter back inlayer filter piece and outer filter piece on remaining impurity, dismantle outer filter piece, can be in order to wash outer filter piece and inlayer filter piece respectively.

Preferably, the filter device for a pipe further includes a stopper 3. Outer filter 21 and the inlayer filter piece 22's cooperation mode can be clearance fit, outer filter 21 is though the cover locates inlayer filter piece 22 promptly, nevertheless with inlayer filter piece 22 between still leave the clearance, outer filter 21's one end contacts with base 1, outer filter 21's the other end is connected with spacing portion 3, at this moment, spacing portion 3 is used for the position of fixed outer filter 21, and block the material, prevent that the material from directly flowing from the tip of base 1 of keeping away from of filter part 2.

Preferably, the stopper 3 may include a stopper end cap 31, a bolt 32, and a nut 33. The limiting end cover 31 is buckled at one end, far away from the base 1, of the outer-layer filtering piece 21, the bolt 32 penetrates through the limiting end cover 31 and is detachably and fixedly connected with the limiting end cover 31, the bolt 32 is fixedly connected with the base 1, the nut 33 is in threaded connection with the bolt 32, and the nut 33 is located on one side, far away from the base 1, of the limiting end cover 31.

It is specific, spacing end cover 31 can be circular metal sheet, the round is formed with convex border around the circular metal sheet, make spacing end cover 31 just can detain the one end of establishing at outer filter piece 21 of keeping away from base 1, the convex border of spacing end cover 31 can laminate in the surface of outer filter piece 21, at this moment, spacing end cover 31 can be followed the removal of the outer filter piece 21 of restriction in axial and radial two directions, prevent that the position of outer filter piece 21 from taking place the skew, and prevent that the material from the direct outflow of this end of outer filter piece 21. The bolt 32 is located the axis position of inner filter member 22 to run through spacing end cover 31, bolt 32 and spacing end cover 31 between the detachable connection. One end of the bolt 32 protrudes beyond the limit end cap 31 and the other end extends within the filter house 2 towards the base 1. The other end of the bolt 32 may be fixedly connected to the base 1 via a single metal plate, and specifically, to ensure the circulation efficiency of fluid passing through the central opening of the base 1, the metal plate may be a rectangular metal plate and vertically disposed with respect to the base 1, two end portions of the metal plate in the length direction are respectively welded to the inner surface of the central opening of the base 1, one side of the metal plate in the width direction is welded to the end portion of the bolt 32 extending into the filter portion 2, and the nut 33 is mounted on the bolt 32 and located on one side of the limit end cap 31 far away from the base 1, that is, the nut 33 is mounted at one end of the bolt 32 extending beyond the limit end cap 31.

During the use, adjust the position of spacing end cover 31, establish spacing end cover 31 lock in the outer one end of filtering piece 21 of keeping away from base 1, the position of nut 33 on bolt 32 is located in the back adjustment, twist nut 33 to and spacing end cover 31 looks butt soon, and then make spacing end cover 31 can with outer filtration piece 21 in close contact with to prevent that spacing end cover 31 from coming off because of the impact of material in the use.

Preferably, the inner and outer filter members 22, 21 may be stainless steel wire mesh. For example, the metal sleeve may be provided with filter holes uniformly, the diameter of the filter holes formed in the outer filter member 21 is larger than that of the filter holes formed in the inner filter member 22, and the density of the filter holes formed in the inner filter member 22 is larger than that of the filter holes formed in the outer filter member 21.

Furthermore, according to a second aspect of the present invention, there is provided a pipe comprising a flange and a filtering apparatus for a pipe as described above, the filtering apparatus for a pipe being installed at the flange of the pipe, for example, a flange where the pipe is connected to other equipment. Specifically, when filter equipment for the pipeline is installed in the flange, the external diameter of base 1 is greater than the central trompil of flange, and the external diameter of filter house 2 is less than the central trompil of flange, and the pipeline is worn to locate along the central trompil of flange by filter house 2, and the last sealing member of base 1 contacts with the flange, and base 1 and sealing member joint are outside the central trompil of flange.

Preferably, the flange may be provided with a limiting step, that is, an annular concave portion is formed around a central opening of a surface plane of the flange, so that the base 1 and the sealing member are clamped in the annular concave portion of the flange when the filtering device for pipelines is installed.
