Description

Technical Field

[0001] This utility model relates to the field of mud treatment equipment technology, and in particular to a mud tank that prevents solid phase deposition of mud. Background Technology

[0002] Mud tanks are essential pieces of equipment in drilling, tunnel construction, and building engineering. They are mainly used for storing, circulating, and processing engineering mud. Mud is a suspension mixture composed of liquid and solid particles. During storage, these solid particles will settle due to gravity, which will affect the performance of the mud and the subsequent processes.

[0003] To address the issue of solid particle settling, existing mud tanks typically incorporate agitators inside the tank. The rotation of the agitator blades maintains the fluidity of the mud, keeping the solid particles in suspension. However, traditional agitators are mostly located in the center of the tank. For tanks, especially square tanks, the agitator blades cannot effectively cover the bottom corners and edges, resulting in very weak fluid dynamics in these areas and creating dead zones.

[0004] The existence of these dead zones in the mixing process causes solid particles to accumulate and harden at the bottom edge and corners of the tank, forming a stubborn solid deposit layer. This deposit not only severely reduces the effective volume of the mud tank and damages the uniformity of the mud, but also makes it difficult to completely remove these deposits when the equipment is shut down for maintenance. This requires a lot of manpower and time, greatly reducing work efficiency and equipment turnover rate.

[0005] Therefore, this utility model proposes a mud tank to prevent solid phase deposition in mud, in order to overcome the shortcomings of the prior art. Utility Model Content

[0006] In the existing technology, the bottom edge and corner areas of the mud tank used to prevent solid phase deposition of mud have formed a stirring dead zone, which leads to the accumulation and deposition of solid particles. This not only reduces the uniformity of the mud, but also brings difficulties to subsequent cleaning and maintenance. The present invention aims to provide a mud tank with an improved structure that can effectively solve the above problems and prevent solid phase deposition of mud.

[0007] This utility model provides a mud tank for preventing solid phase deposition of mud, comprising: a storage tank, a top cover fixedly connected to the top of the storage tank, an agitator penetrating the top cover and extending into the interior of the storage tank, an agitator blade rotatably connected to the agitator located on the lower side of the inner outer wall of the storage tank, and a guide plate and reinforcing ribs.

[0008] The guide plate has a structural feature of extending downwardly from the inner wall of the storage tank towards the center, and the bottom end of the guide plate extends to the area below the stirring blade.

[0009] Furthermore, the storage tank, the stirring blade, and the guide plate are fixedly connected to the lower part of the inner wall of the storage tank via the guide plate, and are combined in such a way that the bottom end extends to the area below the stirring blade. The agitator is used to drive the stirring blade to rotate to stir the mud in the storage tank. The reinforcing ribs are fixedly connected to the outer wall of the storage tank and are distributed along the height direction of the storage tank.

The outer wall of the mud gun is slidably connected to the top left side of the top cover, and the mud gun is slidably fitted inside the movable groove for rinsing or auxiliary stirring inside the storage tank.

[0011] Preferably, the upper cover has a mud discharge port on its inner front side, which is connected to the internal space of the storage tank. The upper cover also has vent holes on its inner front and rear sides to discharge the gas generated during the stirring process inside the storage tank.

[0012] Preferably, a sand-cleaning port is provided on the rear right side of the storage tank, which is connected to the bottom of the storage tank. A sand-cleaning door is fixedly connected to the front right side of the storage tank. The sand-cleaning door is configured to cooperate with the sand-cleaning port and is used to open during cleaning and maintenance to remove residual mud and sediment inside the storage tank.

[0013] Preferably, a connecting pipe is provided on the lower front side of the storage tank, and the connecting pipe is located at the bottom of the guide plate, for discharging the processed mud from the inside of the storage tank.

[0037] Reference Figure 1 and Figure 4 As another preferred embodiment, in order to further improve the stirring efficiency and anti-settling effect, the stirring blades 15 are distributed in a spiral or paddle shape at the bottom of the stirrer 11, and the rotation radius of the stirring blades 15 is adapted to the central area extended by the guide plate 8, so as to ensure that the solid particles guided to the center by the guide plate 8 can be fully stirred by the stirring blades 15.

[0038] Working principle:

[0039] When mud needs to be processed, the operator starts the equipment through the control cabinet 3. The mud is injected into the storage tank 1 through the mud discharge port 9 on the cover 16. The control cabinet 3 controls the start of the agitator 11. The agitator 11 then drives the agitator blade 15 to rotate at high speed inside the storage tank 1. The high-speed rotation of the agitator blade 15 generates a strong shearing and stirring effect on the mud, keeping the solid particles in the mud in a suspended state and preventing the solid particles from agglomerating and settling.

[0040] During the mixing process, the guide plates 8 located around the lower part of the inner wall of the storage tank 1 play a key role. The structure of the guide plates 8 extending downward from the inner wall of the storage tank 1 towards the center actively guides the solid particles that tend to settle in the edge and corner areas of the tank to the central area of ​​the storage tank 1, that is, the strong mixing area of ​​the stirring blades 15. The particles guided to the center are immediately dispersed again by the high-speed rotating stirring blades 15 and mixed into the mud, thereby achieving anti-settling treatment of the entire interior of the storage tank 1, especially the dead corner areas.

[0041] Throughout the operation, the mixing blades 15 and the guide plate 8 work together to ensure the high uniformity of the mud. The gas generated during the mixing process is discharged through the vent holes 10 on the top cover 16. The reinforcing ribs 14 on the outer wall of the storage tank 1 ensure the stability of the tank structure under high-intensity mixing. The cable trough 4 provides a neat wiring layout for the control cabinet 3 and the mixer 11. The railing 2 provides safety protection for the top platform. After the processing is completed, the uniformly mixed mud is discharged through the connecting pipe 5 on the lower front side of the storage tank 1. When the equipment stops running and needs cleaning and maintenance, the staff can open the sand cleaning door 7 and use the sand cleaning port 6 to rinse and clean the residue inside the storage tank 1. If there are stubborn deposits, the mud gun 13, which is slidably connected in the moving groove 12 on the top of the top cover 16, can be used to flush the dead corners with high pressure.
