Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine mud tank technology, specifically to an anti-clogging device for the suction well of a mud tank. Background Technology
[0002] Offshore vessels typically use mud tanks to store and transport mud, and connect to the receiving equipment of the offshore platform via their own pipelines. The mud is then precisely transported to the mud storage equipment on the offshore platform via mud pumps, or used directly, thus completing the transfer and replenishment of mud.
[0003] However, during actual transport, the mud contains large solid impurities such as sand and rock fragments, and it will settle and harden when left to stand. Therefore, the mud is very prone to accumulating and clogging at the suction port of the transport pipeline, that is, accumulating and clogging in the suction well of the mud tank. Traditional mud tanks are usually equipped with agitators to agitate the mud, which can alleviate the sedimentation of the mud to some extent. However, since the suction well is usually protruding from the bottom of the mud tank, the agitator cannot effectively agitate the mud accumulated in the suction well. This makes the suction well a disaster area for impurities to accumulate and mud to harden, making the blockage of the suction port of the mud tank transport pipeline a high-frequency problem in marine engineering operations.
[0004] Once a blockage occurs, crew members need to go down into the cabin and manually clean the impurities and hardened mud accumulated in the suction well using tools such as iron hooks. This manual cleaning method is not only extremely labor-intensive, but also seriously affects operational efficiency and brings many inconveniences to the overall operation of the ship. Utility Model Content
[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is to provide an anti-clogging device for the suction well of the mud tank, which can blow the mud at the suction port of the mud tank conveying pipeline to rotate, so as to avoid the mud from standing still, accumulating and clogging in the suction well for a long time.
[0006] To achieve the above objectives, this utility model provides an anti-clogging device for a mud tank suction well. The mud tank is installed on an offshore vessel, and the suction well is installed on the mud tank. The anti-clogging device includes an air compressor, an air supply pipe, an air supply base, and multiple nozzles. The air compressor is provided with an air outlet for outputting compressed air. One end of the air supply pipe is connected to the air outlet of the air compressor, and the other end is connected to the air supply base. The air supply base is installed inside the suction well and has an inner cavity. The multiple nozzles are all installed on the air supply base, and one end of each nozzle is connected to the inner cavity of the air supply base.
[0007] Furthermore, the air supply base is configured as a circular pipe, with one end of the circular pipe connected to the other end, and one end of the air supply pipe connected to the air outlet of the air compressor, and the other end connected to the circular pipe.
[0008] Furthermore, a one-way valve is provided on the nozzle.
[0009] Furthermore, multiple nozzles are all inclined relative to the axis of the suction well, and the angle between the axis of the nozzle and the axis of the suction well is set to 30°-60°.
[0010] Furthermore, the angle between the axis of the nozzle and the axis of the suction well is set to 45°.
[0011] Furthermore, it also includes a controller for controlling the start and stop of the air compressor, the controller being electrically connected to the air compressor.
[0012] As described above, the anti-clogging device for mud tank suction wells according to this utility model has the following beneficial effects:
[0013] By setting up an air compressor, air supply pipe, air delivery base, and nozzle, production is simple and operation is convenient. It can blow the mud in the suction well to rotate, keeping the mud in a dynamic state and preventing it from sitting for a long time. This solves the problem of mud tank suction well blockage. Mud stored in the mud tank for a long time only needs to be blown a few times a day to prevent the mud in the suction well from settling, clumping, and blocking. This frees up the crew from the work of manually cleaning the suction well. At the same time, it can also protect the mud pump to a certain extent and prevent the mud pump from overloading.

[0021] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0022] See Figures 1 to 2 This utility model provides an anti-clogging device for a mud tank suction well. The mud tank 5 is installed on an offshore vessel, and the suction well 6 is installed on the mud tank 5. The anti-clogging device includes an air compressor 1, an air supply pipe 2, an air supply base 3, and multiple nozzles 4. Specifically, the air compressor 1 is installed on the offshore vessel and has an air outlet for outputting compressed air. One end of the air supply pipe 2 is connected to the air outlet of the air compressor 1, and the other end is connected to the air supply base 3. The air supply base 3 is installed inside the suction well 6 and has an inner cavity. Multiple nozzles 4 are installed on the air supply base 3, and one end of each nozzle 4 is connected to the inner cavity of the air supply base 3. Specifically, the number of nozzles 4 can be flexibly increased or decreased according to the actual diameter of the suction well 6 to meet the usage requirements of suction wells 6 of various sizes.
[0023] The basic working principle of the anti-clogging device for the suction well of the mud chamber involved in this utility model is as follows: When in use, the air compressor 1 is started, and the air compressor 1 outputs compressed air through its air outlet. The compressed air is then sent to the air supply base 3 through the air supply pipe 2, and further sprayed out from multiple nozzles 4, thereby blowing away or agitating the slab mud and impurities in the suction well 6, so that the mud is in an active state and avoids it from being stagnant for a long time. The mud stored for a long time only needs to be blown a few times a day to effectively prevent the mud in the suction well 6 from settling, clumping and clogging.
[0024] See Figures 1 to 2 The present invention will be further described below with reference to a specific embodiment:
[0025] In this embodiment, see Figure 1 , Figure 2 As a preferred design, the air supply base 3 is configured as a circular pipe, with one end of the circular pipe connected to the other end. One end of the air supply pipe 2 is connected to the air outlet of the air compressor 1, and the other end is connected to the circular pipe. The circular pipe is ring-shaped, which facilitates the transport of mud and allows the outer edge of the circular pipe to abut against the inner wall of the suction well 6 for easy installation.
[0026] In this embodiment, see Figure 1 , Figure 2 As a preferred design, a one-way valve is provided on the nozzle 4. By setting the one-way valve, the nozzle 4 can be prevented from being blocked by mud, thus extending its service life and ensuring reliable operation.
[0027] In this embodiment, see Figure 1 , Figure 2 As a preferred design, multiple nozzles 4 are all inclined relative to the axis of the suction well 6, and the angle between the axis of the nozzle 4 and the axis of the suction well 6 is set to 30°-60°. Preferably, the inclination direction of multiple nozzles 4 relative to the axis of the suction well 6 is the same. By inclining the nozzles 4, on the one hand, it is easier to create a rotating airflow, so that the air ejected can form a tangential force, which in turn facilitates the rotation of the hardened mud and impurities, generating a continuous shearing effect, and effectively removing the hardened mud and impurities from the inner wall of the suction well 6; on the other hand, it can form a circulation effect, which facilitates the air to circulate along the inner wall of the suction well 6, thereby increasing the coverage of the airflow ejected from the nozzles 4 and reducing the blind spots that the airflow cannot reach.
[0028] In this embodiment, see Figure 1 , Figure 2 As a preferred design, the angle between the axis of nozzle 4 and the axis of suction well 6 is set to 45°, which can further optimize the flow pattern of air ejected from nozzle 4, avoid the generation of negative pressure eddies and turbulent backflow eddies, and improve its functional practicality.
[0029] In this embodiment, see Figure 1 , Figure 2 As a preferred design, it also includes a controller for controlling the start and stop of the air compressor 1. The controller is electrically connected to the air compressor 1. When in use, the air compressor 1 is started by controlling the controller, and when not in use, the air compressor 1 is stopped by controlling the controller, which improves the convenience of operation, ensures personnel safety, and avoids dangerous environments.
[0030] As can be seen from the above, the anti-clogging device for the mud tank suction well of this utility model has the following beneficial effects:
[0031] By setting up an air compressor 1, an air supply pipe 2, an air supply base 3, and a nozzle 4, production is simple and operation is convenient. It can blow the mud in the suction well 6 to rotate, keeping the mud in an active state and preventing it from sitting for a long time. This solves the problem of blockage in the mud tank 5 and suction well 6. Mud stored in the mud tank for a long time only needs to be blown a few times a day to prevent the mud in the suction well 6 from settling, clumping, and blocking. This frees up the crew from the work of manually cleaning the suction well 6. At the same time, it can also protect the mud pump to a certain extent and prevent the mud pump from overloading.
[0032] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
[0033] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
