[0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles. It is connected by pipes, pipe connectors and valves. Pipes are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices.

[0003] Currently, the transportation of petroleum, chemical, and natural gas requires pipeline systems with precise dimensions and shapes. Therefore, stainless steel drawn tubes are mostly used for transportation. Lubricating grease is required during the production process of drawn tubes, so the lubricating grease must be cleaned off when the pipes are delivered. In the existing pipeline degreasing process, workers generally use a crane to lift the bundled drawn tubes into a cleaning tank on site, and then use dichloromethane cleaning agent in the cleaning tank to clean the grease.

[0004] However, because dichloromethane cleaning agents are highly volatile (boiling point 40°C), volatilization can easily lead to material waste. The volatilized cleaning agent can also cause environmental pollution, which in turn affects the health and safety of workers operating on-site.

[0038] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0040] like Figure 1 As shown, the present application provides a pipeline low-temperature oil removal equipment, comprising a plant 1 and a cold storage 2 provided inside the plant 1. The temperature inside the cold storage 2 is controlled at 0-5°C to ensure that the volatilization of the cleaning agent is very small at this temperature. In addition, the cold storage 2 can be sealed during operation to form a low-temperature and enclosed space for cleaning pipelines.

[0041] It should be noted that the cold storage 2 is an existing pipe-type cold storage, and its specific structure and principle are not described in detail here.

[0042] like Figure 1-Figure 3 As shown, a feeding assembly 4 for automatically transporting pipes is provided on the cold storage 2. The feeding assembly 4 includes a railway 41 provided on the factory building 1 and the cold storage 2. A feeding trolley 42 is provided on the railway 41, and four sets of wheels 44 are rotatably mounted on the bottom of the feeding trolley 42.

[0043] At the same time, a double-axis motor 45 is installed at the bottom of the feeding trolley 42. The two sets of output ends of the double-axis motor 45 are respectively connected to two sets of wheels 44. Driven by the double-axis motor 45, the two sets of wheels 44 rotate to ensure that the feeding trolley 42 can move forward or backward along the railway 41. At the same time, a carrier 43 is provided on the feeding trolley 42 to facilitate the placement of the manufactured pipes, and then to be delivered into the interior of the cold storage 2 through the feeding trolley 42.

[0044] At the same time, a mist suction component 3 is provided on one side of the factory building 1, and the mist suction component 3 is used to absorb the air inside the cold storage 2 to maintain it in a certain negative pressure state;

[0045] like Figure 1 As shown, the mist suction assembly 3 includes an equipment box 31 provided on one side of the factory building 1, a fan is provided inside the equipment box 31, and an exhaust pipe (not shown in the figure) is provided between the fan input end and the cold storage 2, and a filter box 32 is provided on one side of the fan, and an exhaust pipe 33 is provided between the fan output end and the filter box 32;

[0046] Driven by the fan, the air in the cold storage 2 is drawn into the filter box 32 for filtration and discharged through the exhaust pipe 33, thereby ensuring that the cold storage is maintained in a certain negative pressure state without polluting the environment. In addition, since the cold storage is in a negative pressure state, the air in the cold storage 2 will not escape from the cold storage 2 when the pipe to be cleaned enters and exits the cold storage 2.

[0047] In order to clean the pipes that still have lubricating grease, a cleaning assembly 5 is provided inside the cold storage 2;

[0048] like Figure 2 and Figure 5 As shown, the cleaning assembly 5 includes a first primary washing tank 51 provided inside the cold storage 2, and a second primary washing tank 52, a third rinsing tank 53, and a fourth rinsing tank 54 are sequentially provided on one side of the first primary washing tank 51. The first primary washing tank 51 and the second primary washing tank 52 are used for soaking and cleaning the pipes to perform preliminary cleaning on the pipes, and the third rinsing tank 53 and the fourth rinsing tank 54 are used for rinsing the pipes.

[0049] During the initial cleaning of the pipeline, it is difficult to clean due to the large amount of grease inside it. Therefore, ultrasonic generators (not shown in the figure) are provided in the first and second initial cleaning tanks 51 and 52 to assist in the initial cleaning of the pipeline and thus speed up the cleaning process.

[0050] When cleaning the pipeline, the pipeline is soaked and cleaned, and then rinsed, and then transported out through the feeding component 4;

[0051] Continue to refer Figure 5 , and at the same time, a first cleaning bucket 55 corresponding to the first preliminary cleaning tank 51 is provided on one side of the first cleaning tank 51, and the first cleaning bucket 55 is used to store cleaning agent. At the same time, a second cleaning bucket 56, a third cleaning bucket 57 and a fourth cleaning bucket 58 are sequentially provided on one side of the first cleaning bucket 55. Since the structures of the second cleaning bucket 56, the third cleaning bucket 57 and the fourth cleaning bucket 58 are the same as those of the first cleaning bucket 55, for the convenience of description, the first cleaning bucket 55 is used as an example below;

[0052] Continue to refer Figure 5 A drain pipe 59 is provided on the first cleaning bucket 55, and one end of the drain pipe 59 away from the first cleaning bucket 55 is inserted into the interior of the first preliminary cleaning tank 51, so as to facilitate the introduction of the cleaning agent in the first cleaning bucket 55 into the cleaning tank;

[0053] like Figure 2 As shown, a lifting assembly 6 is provided inside the cold storage 2, and the lifting assembly 6 is used to move the carrier 43 on the feeding trolley 42 to the cleaning assembly 5 for cleaning;

[0054] like Figure 2 and Figure 9-10 As shown, the lifting assembly 6 includes a gantry 63 provided above the four groups of cleaning tanks, and two groups of slide rails 62 are fixedly installed on the gantry 63. At the same time, a slide 66 is slidably provided on both groups of slide rails 62, and a servo motor (not shown in the figure) is fixedly installed on one side of the slide 66. The output end of the servo motor is provided with a gear so that the gear rotates under the drive of the servo motor, and a rack 67 meshing with the gear is provided on one side of the slide rail 62 so that the gear cooperates with the rack 67 when rotating to drive the slide 66 to move on the slide rail 62;

[0055] Continue to refer Figure 10 , and a mounting frame 61 is commonly mounted on the two sets of slides 66, and a chain lift 64 is fixedly mounted on both ends of the mounting frame 61. The chain lift 64 is a prior art, such as the patent with authorization announcement number CN203247050U. The specific structure and principle are not described in detail here. It should be noted that the servo motor and the chain lift 64 are controlled by a PLC system to facilitate operation by staff outside the cold storage 2;

[0056] At the same time, a lifting arm 65 is fixedly mounted on the chain lift 64, and a bottom plate (not shown in the figure) adapted to the carrier 43 is fixedly mounted on one side of the lifting arm 65 to support the carrier 43. It should be noted that, in the initial state, one set of chain lifts 64 drives the lifting arm 65 to be in a lowered state, so that the feeding trolley 42 first abuts one end of the carrier 43 against the bottom plate, and then the other set of chain lifts 64 drives the lifting arm 65 to descend, and then the feeding trolley 42 abuts the other end of the carrier 43 against the bottom plate to clamp the carrier 43;

[0057] Then, driven by the chain lifter 64, the carrier 43 is lifted, so that when the slide 66 moves, the carrier 43 is synchronously driven to move, so as to be transported to the cleaning assembly 5 for cleaning.

[0058] At the same time, a circulation component 7 is provided on one side of the cleaning component 5, and the circulation component 7 is used to circulate the cleaning agent in the cleaning tank to further improve the cleaning operation of pipeline degreasing;

[0059] like Figure 5-Figure 7 As shown, the circulation assembly 7 includes a first water pump 73 provided on one side of the first washing bucket 55, and a second water pump 74, a third water pump 75 and a fourth water pump 76 are sequentially provided on one side of the first water pump 73. Since the second water pump 74, the third water pump 75 and the fourth water pump 76 have the same structure, for the convenience of description, the first water pump 73 is used as an example below;

[0060] A second circulation pipe 72 is provided at the output end of the first water pump 73, and the end of the second circulation pipe 72 away from the first water pump 73 is inserted into one end of the first pre-wash tank 51. At the same time, a first circulation pipe 71 is provided at the input end of the first water pump 73, and the end of the first circulation pipe 71 away from the first water pump 73 is inserted into the other end of the first pre-wash tank 51.

[0061] Driven by the first water pump 73, the cleaning agent in the first primary washing tank 51 is circulated through the cooperation of the two sets of circulation pipes, thereby ensuring that the cleaning agent penetrates into every corner of the pipe to improve the cleaning effect;

[0062] Continue to refer Figure 7 In order to reduce the volatilization of the cleaning agent when it is not in use, a diverter pipe 77 is provided on the second circulation pipe 72, and a first valve 78 and a second valve 79 are provided on the second circulation pipe 72 and the separation pipe, respectively. In the initial state, the second valve 79 is closed and the first valve 78 is opened to control the opening of the second circulation pipe 72 and the closing of the separation pipe, so as to facilitate the circulation operation of the cleaning agent.

[0063] Continue to refer Figure 7 At the same time, a filter 710 is provided at the end of the diversion pipe 77 away from the second circulation pipe 72. The filter 710 is provided with a multi-layer filter screen (not shown in the figure) inside to intercept large particles in the cleaning agent. A return pipe 711 is provided between the bottom of the filter 710 and the first cleaning bucket 55.

[0064] When cleaning is completed, the first valve 78 is closed and the second valve 79 is opened. Driven by the first water pump 73, the cleaning agent in the first primary cleaning tank 51 is pumped into the filter 710 for filtration and flows into the first cleaning bucket 55 through the return pipe 711 for storage.

[0065] At the same time, since there is a lot of grease inside the pipeline during the initial cleaning, the cleaning ability of the cleaning agent in the first initial cleaning tank 51 will decrease after long-term use. In order to improve the utilization rate of the cleaning agent, an extraction component 8 is provided on one side of the circulation component 7 to extract the cleaning agent from the four groups of cleaning barrels and send it to the external regeneration system;

[0066] like Figure 8 As shown, the extraction assembly 8 includes an extraction pump 81 provided on one side of the first water pump 73, and a extraction pipe 82 is provided at the input end of the extraction pump 81. Four groups of connecting pipes are provided on the extraction pipe 82. The ends of the four connecting pipes away from the extraction pipe 82 are respectively connected to the bottoms of the four groups of cleaning buckets, thereby extracting the cleaning agent in the four groups of cleaning buckets. In addition, a third solenoid valve is provided on each of the four connecting pipes to control the opening and closing of the four connecting pipes, thereby realizing the separate extraction of the cleaning agent in the four groups of cleaning buckets.

[0067] At the same time, a first feeding double-ended pipe 83 is provided between the output end of the extraction pump 81 and the first cleaning bucket 55 and the second cleaning bucket 56, and the first feeding double-ended pipe 83 is provided with a first solenoid valve 84 and a second solenoid valve 85 to control the opening and closing of the diversion end of the first feeding double-ended pipe 83 so that the cleaning agent can enter the first cleaning bucket 55 or the second cleaning bucket 56 separately. At the same time, a feeding pipe 87 is provided on the first feeding double-ended pipe 83, and the end of the feeding pipe 87 away from the first feeding double-ended pipe 83 is connected to the external regeneration system;

[0068] When the cleaning agent capacity in the first cleaning bucket 55 decreases, the extraction pump 81 extracts the cleaning agent in the first cleaning bucket 55 and discharges it into the external regeneration system through the first feeding double-ended pipe 83 and the second feeding pipe 87 for repair;

[0069] Continue to refer Figure 8 At the same time, a second feeding double-ended pipe 86 having the same structure as the first feeding flow pipe is provided on the third cleaning barrel 57 and the fourth cleaning barrel 58. One end of the second feeding double-ended pipe 86 away from the third cleaning barrel 57 and the fourth cleaning barrel 58 is connected to an external cleaning agent storage tank;

[0070] When the cleaning agent in the first cleaning bucket 55 is extracted, the cleaning agent in the second cleaning bucket 56, the third cleaning bucket 57 and the fourth cleaning bucket 58 is extracted separately in turn by the extraction pump 81 and discharged into the first cleaning bucket 55, the second cleaning bucket 56 and the third cleaning bucket 57 in turn, and then the cleaning agent in the external cleaning agent storage tank is discharged into the fourth cleaning bucket 58 through the second feeding double-headed pipe 86 to improve the utilization rate of the cleaning agent.

[0071] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art.
