Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a mud pool used for separating mud and water. Background Art

[0002] Mud is a semi-colloidal suspension formed by small particles of clay dispersed in water and mixed with water. It is composed of clay and water as basic raw materials, among which clay is the most important component of mud.

[0003] In the prior art, mud has a wide range of applications, and its main functions include maintaining wellbore stability, lubricating and cooling the drill bit, controlling formation pressure, and transporting rock cuttings and drilling fluid. The properties of mud usually include physical stability and chemical stability, appropriate specific gravity, no excessive bubbles, good thixotropy, etc. For example, mud can form a thin and tough mud skin on the hole wall, which can protect the hole wall and prevent collapse, block drop and other accidents such as stuck and clamped drills; the structural strength of the mud can be used to suspend rock powder to prevent drilling burial accidents; the mud has a certain viscosity, which can plug leaks, prevent leakage, and reduce the consumption of flushing fluid.

[0004] However, the mud contains a large amount of organic and inorganic pollutants. If it is discharged directly without treatment, it will cause serious pollution to the environment. It is necessary to use the mud pool to recycle the mud. The subsequent mud treatment methods include stirring treatment, screen filtration, centrifugal separation, etc. However, after the mud is directly treated, the subsequent operations such as cast-in-place piles need to make new mud, resulting in a lot of waste. Therefore, it is necessary to recycle the original mud to improve the utilization rate of the mud. Utility Model Content

[0026] like Figure 1-Figure 2 As shown, a mud pool for separating mud from water includes a mud pool skid body, a primary treatment mechanism 4 arranged in the mud pool skid body, and a secondary treatment mechanism 5 connected to the primary treatment mechanism 4; the mud pool skid body includes a skid base 1, a mud pool body 2 arranged in the skid base 1 and used to store mud, and a pipeline is laid in the mud pool body 2 and connected to the inlet of the primary treatment mechanism 4 through a mud pump 3; the primary treatment mechanism 4 includes a water and mud dual-item separator, and a drainage outlet and a mud discharge outlet are respectively arranged in the dual-item separator, and the mud discharge outlet is connected to the inlet of the secondary treatment mechanism 5.

[0027] Compared with the prior art, in the prior art, the mud pool at the construction site is mainly excavated on site, and the surface of the mud pool is covered with concrete to form the mud pool body 2, and the post-processing and stirring of the mud are all carried out in the mud pool. The treatment methods of the used mud include stirring treatment, screen filtration, centrifugal separation, etc. These treatment methods can effectively remove impurities and pollutants in the mud, improve the purity and stability of the mud, and provide the possibility for the reuse of the mud. The main advantage of this treatment method is that it is cheap and can save costs to a great extent, but the disadvantage is that: on the one hand, it may pollute the surrounding soil; on the other hand, the excavation of the mud pool is limited by the on-site construction site environment and is not suitable for every construction site. In the utility model, the skid-mounted body is firstly adopted to directly integrate the traditional mud pool on the skid-mounted body, which reduces the excavation link of the mud pool on the construction site, and the mud pool installed on the skid-mounted body can be directly transported to the site for use. Secondly, the primary treatment mechanism 4 is directly integrated on the skid body, and the pipes and mud pump 3 can be installed in the factory, reducing the connection work on site. In addition, the utility model adopts multi-stage treatment to effectively separate the mud and slurry, and recycle and reuse it, saving economic costs and reducing pollution.

[0028] The secondary processing mechanism 5 includes an extrusion trolley, and an extrusion die and a top pressing mechanism are arranged on the extrusion trolley. The extrusion die includes a plurality of extrusion plates 7, and a transmission belt 6 is arranged below the extrusion plates 7. Guide rods 9 are arranged on the top and bottom of the extrusion plates 7, and guide grooves adapted to the guide rods 9 are arranged on the extrusion trolley.

[0029] The extrusion plate 7 is provided with a rubber cover 8, which is a water-impermeable material and has a plurality of shallow pits on the surface. The extrusion trolley is provided with a plurality of grouting pipes, and each grouting pipe is connected to adjacent extrusion plates 7 respectively.

[0030] The mud discharge outlet is arranged at the bottom of the dual-item separator, and the water discharge outlet is arranged in the middle of the dual-item separator.

[0031] In actual use, the utility model transports the skid-mounted body integrated with the mud pool body 2 and the primary treatment mechanism 4 to the site, takes over the secondary treatment mechanism 5 on site, and connects the mud discharge outlet in the primary treatment mechanism 4 to the mud inlet of the secondary treatment mechanism 5. When in use, the mud pool body 2 is used for storage and mixing of mud, etc., as in the traditional way. When the mud needs to be recycled and reused in the later stage, the mud pump 3 with muddy water is used to pump the mud pump 3 into the primary treatment mechanism 4. Specifically, the primary treatment mechanism 4 is a treatment tower including a double separator, and the mud discharge outlet is set at the bottom of the primary treatment mechanism 4, while the drainage outlet is set in the middle of the primary treatment structure. Through sedimentation, the mud with a large number of particles will settle downward, mainly concentrated in the middle and lower part of the treatment tower, while the muddy and water part is mainly concentrated in the middle and upper part of the treatment tower.

[0032] The mud that has been preliminarily separated by the primary treatment mechanism 4 is passed into the secondary treatment mechanism 5. The main use principle of the secondary treatment mechanism 5 is to squeeze out a large amount of water contained in the mud through an extrusion operation to complete the solidification treatment of the mud, so as to utilize the later recycling and reuse to achieve effective separation of mud and water. Specifically, the mud that has been preliminarily separated by the primary treatment mechanism 4 is passed through the grouting pipe between the extrusion plates 7. After the grouting is completed, the extrusion plate 7 is pushed to move by the top pressure mechanism to complete the extrusion operation. Among them, the top pressure mechanism can adopt a mechanical structure similar to an oil cylinder or a jack, and its main function is to push the extrusion plate 7 to perform the extrusion operation and reset it after the extrusion is completed. This type of mechanical structure is diverse, and the selectable methods are also diverse, and no restrictions are made here.

[0033] After the extrusion operation is completed, the muddy water is squeezed out, and the remaining mud is in a sandy solidified state. After the extrusion plate 7 loses the extrusion thrust and is reset, the sandy mud will scatter onto the transmission belt 6 and be driven to the outlet through the transmission belt 6 for centralized recycling and reuse, which can effectively reduce the pollution of mud slurry to the surrounding environment and enhance the utilization rate of resources.

[0034] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
