Mud slurry filtering device for bored pile construction

Abstract

The invention discloses a mud slurry filtering device for bored pile construction. The device comprises a filter pipe, a filtering tank and a storage tank, wherein filtering modules are arranged in the filtering pipe and the filtering tank, the filtering module comprises a fixed frame and a movable frame, a sliding groove coaxial with the movable frame is formed in the peripheral surface of the outer side of the movable frame, an annular projection coaxial with the fixed frame is arranged on the circumferential surface of the inner side of the fixed frame, the annular projection is located inthe sliding groove, a plurality of sliding rods are fixedly connected to the groove wall of the sliding groove, a plurality of U-shaped grooves are formed in the inner side circumferential surface ofthe annular projection, a plurality of springs are arranged between the groove wall of the sliding groove and the end surface of the annular projection, the outer side circumferential surface of the movable frame and the inner side circumferential surface of the fixed frame are in sliding seal, and a filtering screen is fixedly connected to the inner side of the movable frame. According to the invention, with the mud slurry device, mud slurry can be effectively isolated, the influence of mud slurry on the filtering module is reduced, the buffering effect of the filtering module is guaranteed,the service life of the filtering module is prolonged, the filtering module can be integrally replaced, the later maintenance is facilitated, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mud filtering devices, in particular to a mud filtering device used in bored pile construction. Background technique [0002] As we all know, mud filtration is an indispensable process in the construction of bored piles, and the quality of its filtration effect also directly affects the effect of the overall construction; the existing mud filtration devices include filter pipes, filter tanks and storage tanks, filter pipes It communicates with the filter tank, the filter tank communicates with the storage tank, and the storage tank is installed under the filter tank; the inside of the filter pipe and the filter tank are both provided with filter screens. [0003] During the mud filtering process, the flow of the mud will impact the filter screen, so it is easy to cause high damage to the filter screen.

[0003] During the mud filtering process, the flow of the mud will impact the filter screen, so it is easy to cause high damage to the filter screen. Although in the prior art, the filter screen is buffered by setting a spring between the block and the filter screen However, due to the open structure between the block and the filter, the mud will enter between the block and the filter, resulting in poor buffering effect during actual use.
