Description

Technical Field

[0001] The present invention relates to the technical field of degreasing equipment, and in particular to a portable ultrasonic degreasing equipment and a use method thereof. Background Art

[0002] Oil is the blood of industry. Many things used in daily life come from oil and become necessities. At the same time, it is also the most important war reserve material for the country. Oil exploitation in my country is carried out on a large scale, and there are thousands of drilling teams. Each well drilled by each drilling team is drilled with a drill bit connected by a series of drill pipes, so the drill pipe plays a vital role in drilling. In order to ensure the quality of the drill pipe connection, the production unit will apply anti-corrosion grease to the threads at both ends of each drill pipe before leaving the factory, and then put a plastic protective cover on the outside. However, the protective cover needs to be removed during drilling, and the anti-corrosion grease needs to be removed. The existing degreasing methods are mainly divided into the following types:

[0003] (i) Mechanical cleaning method: Mechanical cleaning method mainly removes grease on the surface of drill pipe threads by wiping, brushing, etc. (ii) Solvent cleaning method: Solvent cleaning method dissolves grease on the surface of drill pipe threads by chemical solvents. (iii) High-pressure water jet cleaning method: High-pressure water jet cleaning removes grease by flushing with high-pressure water.

[0004] However, the above three methods all have shortcomings:

[0005] (I) Mechanical cleaning method: There are the following shortcomings: (1) Low cleaning efficiency: The existing mechanical and solvent cleaning methods are inefficient and require workers to clean one by one, which is time-consuming and labor-intensive and cannot meet the needs of large-scale rapid cleaning of drill pipes. (2) High labor intensity: When using mechanical and manual wiping methods, workers need to perform repetitive labor for a long time and have a heavy workload. Especially in extreme weather conditions, the labor intensity is even higher. (3) Poor operating environment: Cleaning operations are carried out in high or low temperature environments, which is inconvenient to operate and has a great impact on the workers' health. (4) Poor cleaning uniformity: Manual wiping can easily lead to uneven cleaning, affecting the service life of the thread and the subsequent connection quality. (5) Complex equipment: The mechanical wiping method requires precise mechanical devices, which are complex to operate and have high requirements for equipment maintenance.

[0006] (II) Solvent cleaning method: There are the following shortcomings: (1) Harmful to the human body: Workers are easily exposed to harmful chemical cleaning liquids during the cleaning process, which can cause skin damage and long-term operation is harmful to health. (2) Serious secondary pollution: Mechanical wiping and chemical cleaning produce a large amount of waste liquid and pollutants, which can cause environmental pollution if not handled properly. (3) The equipment is not portable: Most existing cleaning equipment is large in size and heavy in weight, and is not suitable for frequent movement and operation on site. (4) High energy consumption: Solvent cleaning requires a lot of electricity, which is inconvenient to power on site, and consumes a lot of energy and is costly.

[0007] (III) High-pressure water jet cleaning method: There are the following disadvantages: (1) High energy consumption: High-pressure water jet equipment consumes a lot of electricity and is inconvenient to use on site. (2) The equipment is not portable: The equipment is large in size and heavy in weight, which is not suitable for frequent movement and operation on site. (3) Secondary pollution: A large amount of wastewater is generated during the cleaning process, and improper treatment will cause environmental pollution. (4) High labor intensity: The high-pressure water gun needs to be operated manually, which is labor-intensive.

[0008] In view of the technical problems existing in the prior art, a portable ultrasonic degreasing device is urgently needed to solve the problems existing in the above technology. Summary of the invention

[0009] The purpose of the invention is to provide a portable ultrasonic degreasing device and a use method thereof.

[0014] The ultrasonic transmitter 1 is used to transmit the ultrasonic wave it generates to the cleaning tank 2. The present invention utilizes the ultrasonic cavitation effect generated by the ultrasonic transmitter 1 to generate tiny bubbles in the cleaning liquid, and the high-energy shock waves generated by the bubble explosion are used to strip the grease on the surface of the drill pipe thread.

[0019] The waste liquid collection system 5 is used to centrally collect the waste liquid after cleaning to prevent secondary pollution;

[0020] Preferably, the ultrasonic transmitter 1 converts electrical energy into mechanical vibration through a transducer to generate ultrasonic waves in the cleaning fluid; when ultrasonic waves propagate in the cleaning fluid, a large number of tiny bubbles are formed, which continue to grow and shrink under the action of pressure, and finally explode to produce a strong shock wave, thereby stripping the grease on the surface of the drill pipe thread.

[0021] Preferably, the frequency of the ultrasonic transmitter 1 is 40kHz and the power is 100W; the capacity of the cleaning tank 2 is 10L and it is made of stainless steel; the control panel 3 has frequency, intensity and time adjustment functions and is provided with a digital display screen; the storage battery 4 is a lithium-ion battery with a capacity of 5000mAh and can work continuously for 2 hours; the waste liquid collection system 5 includes: a 2L waste liquid collection container, a drain port and a filtration system.

[0026] Step 4, set the cleaning time in the control panel 3 to 30 seconds and start the cleaning process;

[0027] In step 5, the ultrasonic wave generated by the ultrasonic transmitter 1 propagates in the cleaning liquid to form a cavitation effect, and the impact wave generated by the bubble explosion strips the grease on the thread surface.

[0028] Step 6, after the cleaning is completed, the equipment is turned off, the drill pipe is taken out, and the cleaning liquid enters the waste liquid collection system 5 for treatment.

[0029] The present invention has the following advantages:

[0031] (2) Reduce labor intensity: The portable ultrasonic degreasing equipment involved in the present invention is small in size and easy to operate. When using it, workers only need to place the equipment on the drill rod thread head to achieve automatic cleaning, which reduces the labor intensity of manual operation.
