Description

Technical Field

[0001] This utility model relates to the field of oil pipe processing technology, and in particular, to an air blowing device for impurities on the inner wall of an oil pipe. Background Technology

[0002] The cleanliness of the inner wall of oil pipes is crucial for the normal operation of the oil transportation system. If oil pipes fabricated on-site are installed directly into the oil transportation system without being cleaned, impurities such as welding slag and rust on the inner wall of the pipes will enter the oil, causing serious oil contamination. In severe cases, this can render the entire tank of oil unusable. Furthermore, particulate impurities remaining on the inner wall of the oil pipes may damage tightly fitted hydraulic components, leading to malfunctions such as valve core jamming and affecting the normal operation of the valves.

[0003] Cleaning the inner wall of oil pipes mainly involves two steps: pickling and dust removal. During pickling, chemical pickling is used to thoroughly remove impurities such as welding slag and rust from the inner wall of the oil pipe, ensuring a clean inner surface. Before installing the pickled oil pipe into the oil transportation system, the aforementioned dust removal step is required to remove dust that has adhered to the inner wall of the oil pipe during storage, thereby ensuring the quality of oil transportation. In the dust removal operation, to facilitate thorough dust removal, stubborn dust needs to be detached from the inner wall of the oil pipe first. Then, a cleaning rod (usually consisting of a wooden stick and a rag wrapped around it) of similar diameter to the inner diameter of the oil pipe is inserted into the inside of the oil pipe for cleaning. Currently, there are two main methods for removing dust from oil pipes. One method is to use a rubber or wooden hammer to tap the outer wall of the oil pipe to shake off the dust. This method has a high probability of damaging the surface of the oil pipe and also requires a lot of manpower, so it has been gradually abandoned. Another method is air blowing dust removal. In this method, the user holds a blower and blows air into one end of the oil pipe. The high-pressure airflow removes stubborn dust adhering to the inner wall of the oil pipe. This method reduces damage to the outer wall of the oil pipe and saves manpower to some extent. However, in actual operation, dust near the air outlet on the inner wall of the oil pipe is easily blown away, while the cleaning effect on dust relatively far from the air outlet is poor. Therefore, the inventor needs to design an air blowing device for removing impurities from the inner wall of oil pipes that saves manpower while ensuring effective dust removal. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in the prior art, the process of removing impurities from the inner wall of oil pipes is time-consuming and laborious, and the dust removal effect is not good. Based on this, this utility model provides an oil pipe inner wall impurity blowing device that is easy to operate and has a good cleaning effect.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an oil pipe inner wall impurity blowing device, including a base, a sliding platform, a blowing pipe, a drive mechanism and an air inlet pipe. The blowing pipe is horizontally arranged and rotatably disposed on one side of the base. The oil pipe is coaxial with the blowing pipe and clamped on the sliding platform. The sliding platform is slidably disposed on the base along the axial direction of the blowing pipe. The drive mechanism drives the blowing pipe to rotate. The air inlet pipe is connected to one end of the blowing pipe. The side wall of the blowing pipe is provided with blowing holes along the axial direction. By sliding the sliding platform, the oil pipe can be moved so that the oil pipe is sleeved on the outside of the blowing pipe.

[0006] Furthermore, one end of the air blowing tube is closed, the air inlet tube is connected to the open end of the air blowing tube, and the diameter of the air blowing hole gradually increases in the direction away from the air inlet tube.

[0007] Furthermore, the base includes a horizontal base and a vertical base, the vertical base is vertically fixedly connected to one end of the horizontal base, the sliding platform is slidably connected to the horizontal base, and the air blowing pipe is rotatably mounted on the vertical base.

[0008] Furthermore, a groove is provided on the horizontal base along the length direction of the horizontal base, and a slider that is slidably connected to the bottom of the sliding platform is fixedly connected to the groove. The upper surface of the sliding platform is set as an arc surface structure that matches the shape of the outer wall of the oil pipe.

[0009] Furthermore, a baffle is fixedly connected to one end of the sliding platform, and a pressure plate is slidably connected to the other end of the sliding platform. The oil pipe is clamped and fixed between the baffle and the pressure plate.

[0010] Furthermore, the pressure plate is slidably engaged with the sliding platform, and a locking bolt is threaded onto the pressure plate, with the end of the locking bolt abutting against the sliding platform.

[0011] Furthermore, a lead screw is rotatably mounted on the side wall of the horizontal base, the lead screw extends into the slide groove, the lead screw passes through the slider and is threadedly connected to the slider, and a drive motor for driving the lead screw to rotate is mounted on the side wall of the horizontal base.

[0012] Furthermore, the vertical base has a first mounting hole and a second mounting hole that are interconnected. The diameter of the first mounting hole is larger than the diameter of the second mounting hole. The air blowing pipe is rotatably installed in the first mounting hole, and the air inlet pipe is fixedly installed in the second mounting hole. One end of the air inlet pipe is inserted into the air blowing pipe.

[0013] Furthermore, the drive mechanism includes a gear ring, a gear, and a gear motor. The gear ring is fixedly sleeved on the outside of the air blowing pipe, the gear motor is fixedly mounted on the vertical base, and the gear is fixedly mounted on the output shaft of the gear motor and meshes with the gear ring.

[0022] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] Please see Figures 1-5 This utility model provides an air blowing device for impurities on the inner wall of an oil pipe, including a base 1, a sliding platform 2, an air blowing pipe 3, a drive mechanism 4, and an air inlet pipe 5. The air blowing pipe 3 is horizontally arranged and rotatably disposed on one side of the base 1. The oil pipe 100 is coaxial with the air blowing pipe 3 and clamped on the sliding platform 2. The sliding platform 2 is slidably disposed on the base 1 along the axial direction of the air blowing pipe 3. The drive mechanism 4 drives the air blowing pipe 3 to rotate. The air inlet pipe 5 is connected to one end of the air blowing pipe 3. Multiple air blowing holes 31 are opened along the axial direction on the side wall of the air blowing pipe 3. By sliding the sliding platform 2, the oil pipe 100 can be moved so that the oil pipe 100 is sleeved on the outside of the air blowing pipe 3.

[0024] In use, the user fixes the oil pipe 100 onto the sliding platform 2. After clamping, the oil pipe 100 and the air blowing pipe 3 are coaxial. Then, the sliding platform 2 is moved, causing the oil pipe 100 to move as well, and the oil pipe 100 is fitted onto the outside of the air blowing pipe 3. High-pressure gas is then injected into the air blowing pipe 3 through the air inlet pipe 5. Subsequently, the high-pressure gas is blown onto the inner wall of the oil pipe 100 through the air blowing hole 31. At the same time, the drive mechanism 4 drives the air blowing pipe 3 to rotate, so that the high-pressure airflow acts on all parts of the inner wall of the oil pipe 100, thereby blowing away the dust attached to the inner wall of the oil pipe 100 and achieving the initial dust removal effect. During the above operation, the user only needs to clamp the oil pipe 100 to be cleaned on the sliding platform 2. The user does not need to hold an air blower to blow air into the oil pipe 100, which saves manpower and improves work efficiency. At the same time, the multiple air outlets 31 arranged axially on the air blowing pipe 3 can ensure that the high-pressure airflow can act on multiple positions on the inner wall of the oil pipe 100, achieving the effect of thorough blowing and cleaning, and greatly improving the cleaning effect.

[0025] The blowing pipe 3 is a circular tube structure with one end open. One end of the blowing pipe 3 is closed. The air inlet pipe 5 is connected to the open end of the blowing pipe 3. The diameter of the blowing hole 31 gradually increases in the direction away from the air inlet pipe 5. That is, the diameter of the blowing hole 31 is smaller closer to the air inlet pipe 5 and larger further away from the air inlet pipe 5. The purpose of this is that the air pressure is relatively high when the air enters the blowing pipe 3 through the air inlet pipe 5. At this time, the smaller blowing hole 31 can ensure that the gas is blown out at a higher pressure, while also saving some airflow to flow to the closed end of the blowing pipe 3, so as to ensure that enough airflow can flow out through the larger air outlet 31. Through the above arrangement, the airflow is reasonably distributed, which helps to thoroughly purge.

[0026] In this embodiment, the base 1 includes a horizontal base 11 and a vertical base 12. The vertical base 12 is vertically fixedly connected to one end of the horizontal base 11. The sliding platform 2 is slidably connected to the horizontal base 11. The air blowing pipe 3 is rotatably mounted on the vertical base 12.

[0027] In a preferred embodiment, a groove 111 is provided on the horizontal base 11 along the length direction of the horizontal base 11, and a slider 21 is fixedly connected to the bottom of the sliding platform 2. The slider 21 is slidably connected to the groove 111. The upper surface of the sliding platform 2 is set as an arc surface structure that matches the shape of the outer wall of the oil pipe 100. In use, the oil pipe 100 is placed in the arc surface structure at the top of the sliding platform 2 to quickly position the oil pipe 100.

[0028] Furthermore, the upper surface of the horizontal base 11 and the lower surface of the sliding platform 2 are both interlocking arc surfaces. The two arc surfaces fit together, which improves the sliding stability between the sliding platform 2 and the horizontal base 11 and helps the horizontal base 11 to move smoothly.

[0029] Please refer to it again. Figure 1 , Figure 2 In a preferred embodiment, a baffle 112 is fixedly connected to one end of the sliding platform 2, and a pressure plate 113 is slidably connected to the other end of the sliding platform 2. The oil pipe 100 is clamped and fixed between the baffle 112 and the pressure plate 113. The shape of the middle part of the pressure plate 113 matches the oil pipe 100, so that the pressure plate 113 can abut against the end face of the oil pipe 100 without obstructing the air blowing pipe 3 from extending into the oil pipe 100. During installation, the oil pipe 100 is first placed on the top of the sliding platform 2, and then the pressure plate 113 is moved to press and fix the oil pipe 100 onto the baffle 112, thereby fixing the oil pipe 100. In this embodiment, the pressure plate 113 is slidably snapped into the sliding platform 2, so that the pressure plate 113 can slide relative to the sliding platform 2 but cannot detach from the sliding platform 2. Specifically, the opposite sides of the pressure plate 113 form edgings, which slidably cover the side edges of the sliding platform 2. The pressure plate 113 is threaded with a locking bolt 114. When the pressure plate 113 moves into position, it presses one end of the oil pipe 100. At this time, the user can tighten the locking bolt 114 so that the end of the locking bolt 114 abuts against the upper surface of the edge of the sliding platform 2, thereby locking the pressure plate 113 onto the sliding platform 2.

[0030] In this embodiment, a lead screw 115 is rotatably mounted on the side wall of the horizontal base 11. The lead screw 115 extends into the slide groove 111, passes through the slider 21, and is threadedly connected to the slider 21. A drive motor 116 is mounted on the side wall of the horizontal base 11. The output shaft of the drive motor 116 is fixedly connected to the lead screw 115. In use, the drive motor 116 is started, driving the lead screw 115 to rotate, which drives the slider 21, along with the sliding platform 2 and the oil pipe 100, to move synchronously, thereby realizing the reciprocating movement function of the oil pipe 100. The drive motor 116 is a forward and reverse reversible motor.

[0031] In this embodiment, the vertical base 12 has a first mounting hole 121 and a second mounting hole 122 that are interconnected. The diameter of the first mounting hole 121 is larger than the diameter of the second mounting hole 122. The air blowing pipe 3 is rotatably installed in the first mounting hole 121, and the air inlet pipe 5 is fixedly installed in the second mounting hole 122. One end of the air inlet pipe 5 is inserted into the air blowing pipe 3 and is rotatable relative to the air blowing pipe 3. The rotatability of the air inlet pipe 5 relative to the air blowing pipe 3 ensures that air is supplied to the air blowing pipe 3 without affecting the rotation of the air blowing pipe 3. To improve the smoothness of the rotation of the air blowing pipe 3, a bearing 123 is installed in the first mounting hole 121, and the air blowing pipe 3 is fixedly connected to the inner ring of the bearing 123. In addition, a sealing ring 124 is provided between the air inlet pipe 5 and the air blowing pipe 3 to improve the sealing of the connection between the two. The sealing ring 124 can be made of silicone or rubber material.

[0032] The drive mechanism 4 includes a gear ring 41, a gear 42, and a gear motor 43. The gear ring 41 is fixedly sleeved on the outside of the air blowing pipe 3. The gear motor 43 is fixedly mounted on the vertical base 12. The gear 42 is fixedly mounted on the output shaft of the gear motor 43 and meshes with the gear ring 41. During operation, starting the gear motor 43 drives the gear 42 to rotate, which in turn drives the gear ring 41 and the air blowing pipe 3 to rotate.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model.
