Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-4, a debris filter for an oilfield cementing ash conveying device comprises an outer shell 1, connecting pipes 2 are fixedly installed at two ends of the outer shell 1, an inner shell 3 is installed on the inner wall of the outer shell 1 (the inner shell 3 is installed through the outer shell 1 and the connecting pipes 2, the inner shell 3 is installed inside the outer shell 1, the connecting pipes 2 are prevented from damaging the inner shell 3, and the inner shell 3 is easy to disassemble and maintain), a filter plate 4 is installed inside the inner shell 3 through bolts, the filter plate 4 is a stainless steel filter plate, a waterproof motor 15 is fixedly installed at the bottom of the filter plate 4, an output shaft of the waterproof motor 15 penetrates through the filter plate 4 through a seal bearing and is fixedly installed with a connecting rod 5, a sliding groove 6 is formed at one side of the connecting rod 5, a sliding rod 7 is slidably installed in the sliding groove 6, a first spring 8 is installed between one end of the sliding rod 7 and the bottom of the sliding groove 6, and the side of the sliding rod 7, far away from the first spring 8, is formed in an arc shape, and the arc-shaped end of the sliding rod 7 is abutted against the inner side of the inner shell 3.
