Detailed Description

The utility model will be explained in more detail by the following examples, the purpose of which is to protect all technical improvements within the scope of the utility model.

1-5, a hot melt polyethylene filter equipment, including sending pipe 1, install on the conveyer pipe 1 and accomodate ring 2, accomodate and install discharging pipe 3 on the ring 2, accomodate the ring 2 rotation and be connected with clearance circle 4.

The cross section of the containing ring 2 is a circular solid hollow rigid circular ring of a revolution body, the circular diameter of the cross section of the containing ring 2 is the same as the diameter of the conveying pipe 1, and the upper end of the containing ring 2 is communicated with the conveying pipe 1.

A filter screen 102 is arranged at the communication part of the right end of the conveying pipe 1 and the containing ring 2, and a transverse filter rod 101 is arranged at the communication part of the left end of the conveying pipe 1 and the containing ring 2.

The inner side outer end of the containing ring 2 is provided with at least twenty circular grooves, and the grooves are rotationally connected with a cleaning ring 4.

The lower extreme of accomodating ring 2 is connected with discharging pipe 3, installs ball valve 301 on the discharging pipe 3.

Twenty cleaning rings 4 together form a tyre-like assembly with a semicircular cross section, and fins are fixed on the side surfaces of the cleaning rings 4, so that the part of the cleaning rings 4 in the conveying pipe 1 can rotate under the pushing of fluid in the conveying pipe 1.

The cleaning ring 4 is rotatably connected in the filtering holes at the corresponding positions of the filtering net 102.
