[0026] Embodiment 1

[0027] See also Figure 1 The hydraulic pipe flushing device provided in this embodiment includes an oil tank 1, a flushing component and a purge component. The flushing component is connected to the oil tank 1 and is used to flush the pipe to be cleaned. The purge component is connected to the flushing component and is used to purge the pipe to be cleaned.

[0028] It can be known that before flushing, the pipe to be cleaned is first purged. The purpose of purging is to quickly remove particles or impurities inside the pipe to be cleaned. Particles are a major cause of blockage in the subsequent flushing process. Therefore, the particles are blown out first, and one end of the pipe to be cleaned is connected to the purging component. The connection method can be a threaded connection or the pipe to be cleaned is connected to the purging component through some existing card joints. The other end of the pipe to be cleaned may not be connected to the flushing device, and it directly leads to the external environment. After the purging is completed, both ends of the pipe to be cleaned are connected to the flushing component to clean the attachments that are difficult to blow off on the inner wall of the pipe to be cleaned. The inside of the oil tank 1 may be filled with cleaning oil, and the flushing component draws the cleaning oil from the oil tank 1 into the pipe to be cleaned. The cleaning oil after cleaning flows into the oil tank 1 to achieve recycling.

[0029] See also Figure 1 and Figure 2 In some embodiments, the flushing component includes an oil inlet pipeline, an oil return pipeline, a filter 302, a flushing oil pump 305 and a flushing manifold 301. The two ends of the oil inlet pipeline are respectively connected to the oil tank 1 and the flushing manifold 301. The flushing manifold 301 is connected to the oil tank 1 through the oil return pipeline. The filter 302 is assembled on the oil return pipeline, and the purge component is connected to the flushing manifold 301.

[0030] It can be understood that one end of the oil inlet pipeline is connected to the bottom of the oil tank 1, and the other end of the oil inlet pipeline is connected to the flushing collection pipe 301. The pipeline to be cleaned is connected to the flushing collection pipe 301. The cleaning oil enters the flushing collection pipe 301 through the oil inlet pipeline, and then enters the pipeline to be cleaned through the flushing collection pipe 301, and finally flows back to the oil tank 1 through the oil return pipeline. The filter 302 filters the cleaning oil before it flows back to the inside of the oil tank 1, thereby effectively avoiding affecting the recycling of the cleaning oil.

[0031] See also Figure 2 In some embodiments, the flushing component further includes an oil filling pipeline and an oil filling pump 304, the oil filling pipeline is connected to the oil tank 1, and the oil filling pump 304 is installed on the oil filling pipeline.

[0032] It can be understood that the oil filling pipeline can be connected to the oil replenishing tank, and the oil filling pump 304 can replenish the cleaning oil in the oil replenishing tank into the oil tank 1 through the oil filling pipeline. When the oil is not replenished, the valve on the oil filling pipeline can be closed. The flushing component can facilitate the oil replenishing operation. The oil filling pump 304 and the flushing oil pump can be controlled by the oil pump control box 303.

[0033] See also Figure 3In some embodiments, the flushing manifold includes a main pipeline, a main control valve and a plurality of pipeline interfaces, the main pipeline is connected to the return oil pipeline, the main control valve and the plurality of pipeline interfaces are assembled on the main pipeline, and the purge component is connected to the main pipeline.

[0034] It can be understood that a number of pipe interfaces can be arranged on the main pipeline, and the pipe interfaces can be threaded interfaces, which can be threadedly connected to the pipes to be cleaned. A control valve can be correspondingly provided on each pipe interface, and the corresponding pipe interface can be selected according to the number and parameters of the pipes to be cleaned. In the cleaning state, both ends of the pipes to be cleaned are connected to the pipe interfaces in the open state. In the purging state, both ends of the return oil pipeline are closed, one end of the pipe to be cleaned is connected to the pipe interface, and the other end is connected to the external environment. During purging, the remaining idle pipe interfaces can be selected to be closed. The flushing manifold with this structure is convenient for various cleaning operations.

[0035] See also Figure 3 In some embodiments, the main pipeline includes a connecting section, a branching section and several branch sections. The connecting section connects the return oil pipeline and the branching section. Several branch sections are assembled on the branching section. The main control valve is assembled on the connecting section, and the pipeline interface is set on the branch section.

[0036] It can be understood that the connecting section can be vertically connected to the branching section, the connecting section is connected to the branching section, the branching section can also be vertically connected to the branching section, the pipeline interfaces can be evenly arranged on the branching section, and the main pipeline of this structure is convenient for operating multiple pipelines to be cleaned.

[0037] See also Figure 1 and Figure 2 In some embodiments, the purge component includes an air compressor and a purge pipeline, and the air compressor is connected to the oil return pipeline through the purge pipeline.

[0038] It can be understood that the air compressor is connected to the branch section through the purge pipe, and the purge component of this structure is simple in structure.

[0039] See also Figure 1 and Figure 2 In some embodiments, the air compressor includes an air pump 201, an air tank 203 and a purge control valve. The air pump 201, the air tank 203 and the purge control valve are all assembled on the purge pipe 202. The air tank 203 is located between the air pump 201 and the return oil pipeline, and the purge control valve is located between the air pump 201 and the air tank 203.

[0040] It can be understood that the air pump 201 compresses the compressed air into the gas tank 203, and the gas in the gas tank 203 enters the branch section through the purge pipe 202, thereby achieving the purge of the inside of the pipeline to be cleaned. The gas tank can well improve the stability of the air pressure of the purge gas. The air pump 201 is controlled by the corresponding air pump control box 204. The purge pipe 202 can also be equipped with a compressed air filter component to filter impurities in the compressed air.

[0041] In some embodiments, the flushing device further includes a heating element, a temperature detection element and a temperature control element. The heating element and the temperature detection element are located in the oil tank 1, and the heating element and the temperature detection element are electrically connected to the temperature control element.

[0042] It can be known that the heating element can be some common heating devices, the temperature detection element can also be some common temperature measuring elements, the temperature measuring elements measure the oil temperature inside the oil tank 1, and the temperature control unit can be some common temperature control devices, which are used to keep the oil temperature at a preset temperature, which can be 60 degrees Celsius.

[0043] It is understandable that the above-mentioned flushing device may further include a base 4, and the above-mentioned components may be placed on the base 4, so as to facilitate the overall movement and transportation.

[0044] Embodiment 2

[0045] This embodiment provides a hydraulic pipe flushing method, which is implemented using the above-mentioned hydraulic pipe flushing device and includes the following steps:

[0046] Connect the pipeline to be cleaned with the flushing component;

[0047] The pipeline to be cleaned is purged by means of a purging component;

[0048] The pipeline to be cleaned is flushed by means of the flushing component.

[0049] It is understandable that the pump outlet pressure should not be set too high before the flushing component is operated. The pump head pressure and the pump outlet relief valve should be slowly increased to a slightly higher level without overflow. The specific value is determined by the resistance loss along the pipeline to be cleaned, so the specific system is different, just follow the above adjustment principles.

[0050] The flushing oil pump 305 of the flushing component should be started at no load and then loaded to avoid excessive current. Conversely, the pressure should be relieved before stopping the pump to avoid excessive losses.

[0051] During the flushing process, you can also knock on the pipe to be cleaned. Do not use a hammer, but a wooden hammer or stick, and use moderate force;

[0052] After flushing for a period of time, it is necessary to regularly check the degree of contamination of the filter core of the filter 302 and replace the filter core in time;

[0053] During the flushing period, regular inspections should be carried out to find oil leaks in each pipeline and deal with them in time. Attention should be paid to changes in oil temperature and pressure, and problems should be found and solved in time.

[0054] If a problem needs to be dealt with during flushing, the pump should be stopped first and then the problem should be dealt with. After the problem is dealt with, the oil stains should be cleaned up in time to keep the site clean.

[0055] From the above description, it can be known that the hydraulic pipe flushing device and method provided by the present invention pre-purges the interior of the pipe to be cleaned by means of a purge component to remove particulate matter inside the pipe to be cleaned, thereby avoiding blockage of the flushing component when flushing the interior of the pipe to be cleaned.

[0056] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
