Description

Technical Field

[0001] The present application relates to the technical field of mud recycling, and in particular to a mud recycling device. Background Art

[0002] Mud is a semi-colloidal suspension formed by tiny clay particles dispersed in water and mixed with water. In colloid chemistry, solid clay is called dispersed phase or solid phase, and water is called medium or liquid phase. If the solid phase is dispersed into molecules or ions, and there is no interface between the solid and liquid phases, it is called a true solution, such as a solution of salt dissolved in water. If the particles dispersed in the liquid phase are composed of many molecules, although the particles are very small, there is an interface. Such a mixture is called a colloidal solution. Various commonly used glues belong to this category. If it is similar to a colloidal solution, but more than 40% of the solid particles are larger than 0.2μm (1μm=0.001 mm), it is called a semi-colloid or suspension, and mud belongs to this kind of semi-colloidal suspension.

[0003] Regarding the mud treatment issue, a large amount of mud waste liquid will be generated during the reverse hole expansion process. If effective measures are not taken, the cost of waste mud treatment will increase significantly.

[0004] For this purpose, the present application proposes a mud recycling device. Utility Model Content

[0005] The present application proposes a mud recycling device to solve the problems raised in the above-mentioned background technology; the device sets a mud overflow pool at the unearthed place of the guide hole, and the solid impurities carried by the mud reflected during the hole expansion are precipitated in the mud overflow pool, and the overflowed mud enters the first circulation pipe. At this time, a vibrating screen is used for the first stage of filtration, and the solid phase with a particle size larger than the mesh is screened out by mechanical vibration. The screened mud is subjected to a secondary filtration by a desander to remove excess sand and gravel, and the sand content is reduced to below %, and then, the treated mud properties are adjusted to the test value through experiments and reused. Finally, a mud pump is used to send the mud liquid to the second circulation pipe for recycling. By setting a rotary joint mechanism, the uninterrupted supply of mud can be guaranteed while the continuous rotation of the drill rod can be maintained, thereby realizing the repeated recycling of thixotropic mud.

[0006] In order to achieve the above purpose, this application adopts the following technical solutions:

[0031] Refer to Figure 1 、 3 、4, a test mechanism 7 is fixedly connected to the outside of the equipment body 1. The test mechanism 7 includes a laboratory 71 which is fixedly connected to the outside of the equipment body 1, and one end of the first circulation pipe 2 extends into the laboratory 71.

At this time, the vibrating screen 51 is used for the first-stage filtration, and the solid phases with particle sizes larger than the mesh holes are screened out by mechanical vibration. The screened mud is subjected to secondary filtration by the desander 61 to remove excess sand and gravel, and the sand content is reduced to less than 5%. Then, by setting the test mechanism 7 and the laboratory 71, after the experiment, the properties of the treated mud are adjusted to the test values and then reused. Finally, by setting the conveying mechanism 9, the mud pump 91, the input pipeline 92 and the output pipeline 93, the mud liquid is conveyed into the cylinder body 101 by the mud pump 91.
