Further, the barrel slot is arranged in the middle of the barrel. The cylinder structure is uniform, the stress is good, and the filtering area of the filter plate is large.

Furthermore, the socket of the cylinder slot is a straight socket, the two side edges of the arc-shaped filter plate are provided with flat-plate-shaped inserting portions, and the flat-plate-shaped inserting portions are matched with the straight socket. The slotting difficulty of the cylinder body is reduced, and the filter can be conveniently inserted.

The utility model has the advantages that: compare in prior art, the filter area of arc filter is big, and the arcwall face is imported towards, and the difficult bending deformation that produces of face when receiving the fluid impact. The filter plate is fixed through the cartridge, so that the filter plate can be conveniently taken out for cleaning or replacement, the operation is convenient, and the maintenance time is short. The utility model discloses a filter, upper cover and barrel pass through flange joint, make things convenient for opening of filter to clear up.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings and a preferred embodiment.

Embodiment mode 1

Referring to fig. 1 and 2, the present embodiment discloses a pipe filter, which includes a cylinder 10, a cylinder flange 101, a flange cover plate 20, an inlet pipe 40, an outlet pipe 50, and an arc-shaped filter plate 30.

The upper end of the cylinder 10 is welded with a cylinder flange 101, and the outer edge of the cylinder flange 101 is provided with a first through hole. The inlet pipe 40 and the outlet pipe 50 are respectively provided at the left and right sides of the cylinder 10, and the two pipes are concentric. The inlet pipe 40 has an inlet flange 41 at one end and an outlet flange 51 at one end of the outlet pipe 50. The flange cover 20 is disposed on the top of the cylinder 10 for sealing the inner cavity of the cylinder. The outer edge of the flange cover 20 is provided with a second through hole adapted to the cylinder flange 101. The flange cover plate 20 is fastened and connected with the cylinder flange 101 through bolts and nuts. Two slots 11 are axially arranged on the inner walls of two opposite sides of the middle part of the cylinder body 10, and the sockets of the two slots incline towards the inlet pipe 40; the bottom of the cylinder 10 is provided with a lower socket 12 matched with the cross section of the arc-shaped filter plate 30, and the lower socket 12 is communicated with the two slots 11; the inner side wall of the flange cover plate 20 is correspondingly provided with an upper socket 21, the arc-shaped filter plate 30 is inserted into the two slots 11 from top to bottom, the lower end of the arc-shaped filter plate is inserted into the lower socket 12, the upper end of the arc-shaped filter plate is inserted into the upper socket 21, and the arc-shaped surface faces the inlet pipe 40. The arc-shaped filter plate 30 divides the inner cavity of the cylinder into two independent cavities, namely a liquid inlet cavity and a liquid outlet cavity. In this embodiment, the arc-shaped filter plate 30 is an arc-shaped plastic hole plate, the plate surface is provided with filter holes 31, the filter holes 31 can be round holes, square holes or strip-shaped holes, and the aperture is smaller than the minimum particle size of impurities in the fluid medium.
