Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a mud liquid recovery device. Background Art

[0002] In order to reduce the pollution of mud to the land, the mud should be recovered in time when pouring concrete. However, since concrete will pollute the mud system, the mud 1 meter away from the bottom of the well shall not be recovered. However, the existing mud recovery device cannot distinguish the mud 1 meter away from the bottom of the well. During the recovery process, all the mud in the pouring well is often recovered, resulting in the contamination of the recovered mud by concrete, which increases the difficulty of reusing the recovered mud. Therefore, we propose a mud liquid recovery device that can maintain the purity of the recovered mud. Utility Model Content

[0021] The minimum connection length between the bottoming response structure and the limiting column 1 is 1 meter, which can ensure that the slurry recovery position is at least 1 meter away from the bottom of the casting well, thereby reducing the degree of mud contamination by concrete and improving the availability of the recovered mud. A connecting component is welded on the top of the limiting column 1, and the side of the connecting component is connected to a mud discharge structure.

The slurry lifting structure includes a lifting pipe 16, and a lifting pump 17 is connected to the top of the lifting pipe 16.

[0024] Preferably, Figure 4 As shown, a retaining rod 6 is welded to the top of the bottom plate 7, and a slideway 5 adapted to the retaining rod 6 is opened on the inner wall of the limiting groove 3. The length of the retaining rod 6 is equal to the length of the slideway 5, and the slideway 5 can limit the sliding path of the retaining rod 6.
