[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a coal slime sedimentation device, which includes a main body 10, a sedimentation tray 20 and a baffle 30. The main body 10 is provided with a circulation channel 101. The sedimentation tray 20 is separately provided from the main body 10, and a plurality of sedimentation trays 20 are provided. The plurality of sedimentation trays 20 are spaced apart and distributed along the extension direction of the circulation channel 101. The sedimentation tray 20 is placed at the bottom of the circulation channel 101, and the sedimentation tray 20 cooperates with the main body 10 to form a sedimentation tank. The baffle 30 is provided in the circulation channel 101, and a plurality of baffles 30 are provided along the extension direction of the circulation channel 101. A sedimentation tray 20 is provided between two adjacent baffles 30 to limit the position of the sedimentation tray 20 in the circulation channel 101.

[0035] By applying the technical solution of the utility model, the device is applied in mine operations. When the sludge water generated by the mine operation passes through the circulation channel 101 of the main body 10, the sludge in the sludge water is concentrated and precipitated into a plurality of sedimentation trays 20 by gravity, and the clean water is discharged from the top, thereby achieving solid-liquid separation. With such a configuration, the suspended solids and sediments in the sewage can be effectively removed. When the sludge is precipitated to a certain extent, the staff directly takes out the sedimentation tray 20 from the main body 10, and cleans the sludge in the sedimentation tray 20. After the cleaning is completed, the sedimentation tray 20 is placed back in the circulation channel 101. In addition, the position of the sedimentation tray 20 in the circulation channel 101 is limited by the baffle 30, and the operation process of taking the sedimentation tray 20 is relatively simple, and does not require complex equipment or highly professional operators. With such a configuration, its design and construction costs are relatively low, and the operation and maintenance costs are also relatively economical.

[0036] In the traditional technical solution, the sedimentation device usually includes only one sedimentation tank. When the sludge needs to be cleaned, special equipment or staff are usually required to enter the sedimentation tank to clean the sludge in the sedimentation tank. The operation is cumbersome and labor-intensive. Compared with the traditional technical solution, in this solution, a plurality of sedimentation trays 20 that are independent of the main body 10 are provided, and the sedimentation trays 20 only need to be placed in the circulation channel 101. Such a setting makes it easy for the staff to take out and clean the sedimentation trays 20 with accumulated sludge. The design and construction cost is relatively low, and the operation and maintenance costs are also relatively economical.

[0037] The present solution does not limit the specific form of the sedimentation tray 20 , as long as the sludge can be precipitated and is easy to take out.

[0038] In the embodiment of the present scheme, the sedimentation tray 20 includes a bottom plate 21 and a baffle 22. The bottom plate 21 is arranged at the bottom of the circulation channel 101. Two baffles 22 are arranged at the two ends of the bottom plate 21, and the two ends of the baffle 22 are respectively abutted against the two side walls of the circulation channel 101, and the two baffles 22 are respectively abutted against the two adjacent baffles 30. Such a setting enables the baffle 22 to form an interception body for intercepting sludge, and blocks the particles in the sludge water. The particles are deposited on the bottom plate 21 after colliding with the baffle 22. Most of the sludge in the sludge water has a certain viscosity, and the sludge is easy to adhere to the bottom plate 21 and the baffle 22. When the sedimentation tray 20 is taken out, the sludge will not fall on the sedimentation tray. In addition, the above setting has a simple structure and a relatively convenient processing process.

Such a configuration can increase the contact area between the barrier rod and the sedimentation tray 20, and improve the stability of the sedimentation tray 20 in the circulation channel 101.
