Description

Technical Field

[0001] The invention relates to the technical field of oil production pipelines, in particular to a metal rust remover for oil production glass glaze anti-corrosion pipelines and a processing method thereof. Background Art

[0002] Oil is flammable, corrosive and volatile. The transportation pipelines for crude oil extraction need to have protection functions against these characteristics. Glass glaze anti-corrosion pipes can be used to transport crude oil on the ground. The temperature of the conveying medium can reach 300°C. It is a functional ceramic coating anti-corrosion pipe formed by surfacing a corrosion-resistant alloy layer on the pipe end and high-temperature cladding of glass glaze on the inner wall. In the process of producing glass glaze anti-corrosion pipes, the inner wall of the pipe needs to be sandblasted and derusted using a rust remover to make its inner surface frosted to facilitate the next step of glazing.

[0003] In the prior art, it is best to clean the sandblasting and rust removal machine before sandblasting, in order to remove the residue and oil stains that may exist on the inner wall of the pipe, prevent the residue from blocking or the sand from slipping, and thus affect the sandblasting effect. However, the current cleaning method usually requires special cleaning equipment, which has high cost and energy consumption. In order to save production costs, the pre-sandblasting process is usually omitted for pipes with fewer stains. Therefore, it is likely to cause uneven sandblasting or increase the sandblasting time to ensure quality, resulting in increased wear and tear on the rust removal machine and affecting its service life.

[0004] In addition, the current rust removal machines will leave certain residues and rust during the rust removal process, requiring an air compressor to blow the inner wall of the pipe body. However, since the density of residues and rust is greater than that of dust, the surface dust and some residues and rust are usually blown away first during the blowing. Continuous blowing or increased wind force is required to completely clean the impurities on the inner wall of the pipe, which takes a long time to blow the pipe and reduces the cleaning efficiency.

[0005] Therefore, in view of this, the present invention proposes a metal rust remover for oil mining using glass glaze anti-corrosion pipeline and a processing method to make up for and improve the deficiencies of the prior art. Summary of the invention

[0016] A method for processing a glass glaze anti-corrosion pipeline for petroleum mining comprises the following steps: Step 1: Pipe end cladding and groove processing: Build up welding at the pipe end to form a welding joint, and the cladding layer is complete without weld nodules or welding slag. Then use an automatic lathe to automate the pipe groove processing. The groove end face should be flush and free of burr defects to facilitate on-site welding construction; Step 2: Rust and dust removal on the inner wall of the pipeline: After the processing of the pipeline port is completed, the inner wall of the pipeline is first pre-treated by sandblasting to ensure that the pipeline is sandblasted and rusted. Then, a rust remover is used for sandblasting and rust removal, and the quality reaches Sa3.0 level requirements. Air is introduced through the air pipe, and the pipe rack is installed to introduce sand particles. Then, the drive part is used to drive the diverter to rotate, so that the semi-arc plate sprays sand particles to remove rust from the inner wall of the pipeline. After rust removal, compressed air is used to blow the inner wall of the pipe body to quickly remove a small amount of residual rust, sand, and dust impurities, reduce the blowing time, ensure that the inner wall of the pipeline is clean, and the surface is in a frosted state, increase adhesion, and facilitate glazing of the inner wall; Step 3: Pipe heating and glaze deposition: After the inner wall of the pipe is treated, the pipe is heated by medium frequency heating, and then the glaze is sprayed and deposited on the inner wall of the steel pipe to form a bright and dense glass glaze layer, which makes the pipe have the properties of high temperature resistance, corrosion resistance, wear resistance and anti-fouling wax deposition; Step 4: Pipe cooling and finished product inspection: After glazing is completed, it is naturally cooled, and then the three indicators of the pipe glaze layer appearance quality, thickness, and leakage points are inspected before delivery. The appearance is smooth, the color is uniform, there are no visible bubbles or cracks, and the thickness of the pipe is greater than or equal to 500 microns. Then, electric spark detection is used to detect leakage points. Only after meeting the standards can it be shipped out of the factory.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the setting of the self-rotating mechanism, the inclined travel wheel and rotating plate are used before rust removal. After the rust remover enters the inner wall of the pipe, the forward thrust and friction force make the travel wheel and the rotating plate spirally walk on the inner wall, driving the wood fiber wiper block and the arc edge scraper on the rotating plate to slide synchronously on the inner wall of the pipe, removing the residue and oil stains on the inner wall of the unblasted pipe, preventing the residue from blocking or the sand from slipping, ensuring the uniformity of the inner wall after sandblasting, improving the quality of sandblasting, and facilitating the uniform adhesion of the next step of glazing. No special cleaning equipment is required, reducing energy and production cost consumption, and the telescopic distance of multiple L-shaped rods can be adjusted at one time through the circular turntable. The traditional travel device may need to be adjusted multiple times for pipes of different sizes, and this patented technology can adapt to pipes of various sizes at one time through the adjustment of the circular turntable, thereby greatly reducing the adjustment time and improving work efficiency. At the same time, the design of the circular turntable allows the operator to easily adjust the telescopic distance of the L-shaped rod without complicated operating procedures, improving the flexibility and convenience of operation, and also helping to improve the safety of the operation.

[0018] 2. Through the setting of the outward-expanded flat-mouthed nozzle, every time the nozzle rotates one circle, the spraying range of sand particles on the inner wall of the pipe per unit time can be increased, thereby improving the sandblasting speed. In addition, the edge cutout of the nozzle is parallel to the rotating shaft after installation, so that the distance between the sprayed sand particles and the inner wall of the pipe can be consistent, thereby ensuring the uniformity of the sandblasting force. In addition, the setting of the semi-arc plate outside the nozzle, the arc surface outer wall of the semi-arc plate can reduce the airflow resistance when the nozzle rotates, and the semi-arc plates on both sides are respectively set up one above and one below on the nozzle, which is equivalent to the nozzles and the semi-arc plates on both sides being symmetrical through the center of the rotating shaft. The semi-arc plate's own gravity can assist the nozzle rotation, thereby improving the rotation speed and facilitating the smooth progress of the sandblasting process.

[0019] 3. After the sandblasting and rust removal is completed, the remaining residues and rust can be first collected by the swinging collection mechanism on the rust remover. Through the setting of the telescopic block and the fixed block, the telescopic block will squeeze and push the fixed block every time it passes through the fixed block, thereby pushing the swing sleeve to rotate a certain distance on the rotating shaft, allowing the collection box to swing back and forth on the inner wall of the pipe, so that it can automatically collect residues and rust in the process of rotating the rotating shaft and moving the rust remover at a uniform speed. Even when the rotating shaft rotates rapidly, the telescopic block does not have enough time for the third spring to rebound due to its fast speed, but the telescopic block can also cause the swing sleeve to vibrate slightly, thereby causing the collection box and the material-diverting plate to vibrate synchronously for collection, and then when using compressed air for purging in the next step, only a small amount of residue needs to be purged, which greatly reduces the purging time and avoids the situation where the impurities on the inner wall of the pipe need to be completely cleaned up by continuous purging or increasing the wind force, effectively improving the cleaning efficiency, and the synchronous reciprocating swing of the material-diverting plate at the entrance of the collection box can effectively break up the accumulated residues and rust, facilitate collection, and prevent the collection box from being stuck.

[0020] 4. The inner wall of the pipeline is cleaned and rust-free simply and effectively by performing the three processes of pre-sandblasting, sandblasting and post-sandblasting. It is convenient for the next step to be carried out efficiently. In the process of mobile sandblasting of the rust remover, the inclined wood fiber wiping block and the arc edge scraper are first spirally slid on the inner wall of the pipeline. The wood fiber wiping block can effectively remove oil stains due to its natural structure and lipophilicity. The arc edge scraper can ensure that when scraping impurities on the inner wall of the pipeline, the damage to the pipeline is reduced, and impurities such as oil stains and residues are effectively cleaned. Then, the rust is removed by sandblasting quickly and evenly through the outward-expanding flat-mouthed nozzle. The outward-expanding flat-mouthed nozzle can also increase the sandblasting area per unit time, ensuring the quality and efficiency of rust removal on the inner wall of the pipeline. Finally, when the shaft rotates, the deposits are broken up at the entrance of the aggregate box by the reciprocating swinging material plate. The material plate can not only prevent blockage and improve material flow efficiency, but also reduce material wear, increase material processing speed, extend the service life of the aggregate box, and effectively collect some residues and rust, so that the next step of the purge process is fast and efficient.

[0030] The effects achieved by this embodiment are as follows: In the prior art, in order to save production costs, the pre-sandblasting process is usually omitted for pipes with less stains, which is likely to cause uneven sandblasting or increase the sandblasting time to ensure quality, resulting in increased use loss of the rust remover and affecting its service life. Compared with the prior art, through the implementation of this embodiment, a self-rotating mechanism 6 is set to enable the walking wheel 62 and the rotating plate 66 to spirally walk on the inner wall through the forward thrust and friction force after the rust remover enters the inner wall of the pipe, driving the wood fiber wiping block 616 and the arc-edge scraper 617 on the rotating plate 66 to slide synchronously on the inner wall of the pipe, removing the residue and oil stains on the inner wall of the un-sandblasted pipe, preventing residue obstruction or sand grains from slipping, and ensuring that the inner wall is uniform after sandblasting, and the telescopic distance of multiple L-shaped rods 69 can be adjusted at one time through the annular turntable 618 to adapt to different pipe sizes.

[0031] For further examples, please refer to Figure 1 , Figures 8 to 10 As shown: The swinging material collecting mechanism 7 includes a rotating shaft 78 fixedly connected to the output end of the driving member 3, the end of the rotating shaft 78 away from the adjusting bracket 2 is rotatably connected to the swing sleeve 73, the top of the swing sleeve 73 is slidably connected to the telescopic block 711, the side of the telescopic block 711 away from the swing sleeve 73 is fixedly connected to the third spring 715, the end of the third spring 715 away from the telescopic block 711 is fixedly connected to the inner wall of the rotating shaft 78, the top of the swing sleeve 73 is provided with an annular groove 712 matched with the size of the telescopic block 711, the top of the swing sleeve 73 is fixedly connected with a fixed block 714 in the corresponding annular groove 712, the bottom of the swing sleeve 73 is slidably connected to the lifting rod 72, the top of the lifting rod 72 is fixedly connected to the second spring 713, and the end of the second spring 713 away from the lifting rod 72 is fixedly connected to the inner wall of the swing sleeve 73.

[0032] The swinging material collecting mechanism 7 also includes a material collecting box 71 fixedly connected to the bottom end of the lifting rod 72, a material removing plate 79 fixedly connected to the middle part of the material collecting box 71, a joint block 74 is detachably installed on the end of the rotating shaft 78 away from the adjusting bracket 2, a baffle 710 is fixedly connected to the side of the rotating shaft 78 close to the swing sleeve 73, a diverter 76 is fixedly installed on the side of the rotating shaft 78 close to the adjusting bracket 2, both sides of the diverter 76 are fixedly connected to nozzles 77, a semi-arc plate 75 is fixedly connected to the top of one nozzle 77, and a semi-arc plate 75 is fixedly connected to the bottom of the other nozzle 77.

[0033] The nozzle 77 is configured to be in an outwardly expanded flat mouth shape with an edge cutout parallel to the rotating shaft 78 , and the material-diverting plate 79 is configured to be in an elongated strip shape extending to the outside of the material collecting box 71 .

[0035] The effects achieved by this embodiment are as follows: In the prior art, surface dust and some residues and rust are usually blown away first during purging, and continuous purging or increased wind force is required to completely clean the impurities on the inner wall of the pipe, which takes a long time to purge the pipe and reduces the cleaning efficiency. Compared with the prior art, through the implementation of this embodiment, a swinging collection mechanism 7 is provided which can use a telescopic block 711 and a fixed block 714 to automatically collect residues and rust during the rotation of the shaft 78 and the uniform movement of the rust remover, so that when compressed air is used for purging in the next step, only a small amount of residue needs to be purged, which greatly reduces the purging time, and the material plate 79 is synchronously swung back and forth at the entrance of the collection box 71, which can effectively break up the accumulated residues and rust for easy collection and prevent the collection box 71 from being stuck.

[0036] Embodiment 2 of the present invention: A method for processing a glass glaze anti-corrosion pipeline for petroleum mining, comprising the following steps: Step 1: Pipe end cladding and groove processing: Build up welding at the pipe end to form a welding joint, and the cladding layer is complete without weld nodules or welding slag. Then use an automatic lathe to automate the pipe groove processing. The groove end face should be flush and free of burr defects to facilitate on-site welding construction; Step 2: Rust and dust removal on the inner wall of the pipeline: After the processing of the pipeline port is completed, the inner wall of the pipeline is first subjected to sandblasting pre-treatment to ensure that the pipeline is sandblasted and rusted. Then, a rust remover is used for sandblasting and rust removal, and the quality reaches the Sa3.0 level requirement. Air is introduced through the air pipe 5, and the pipe rack 1 is installed to introduce sand particles. Then, the driving member 3 is used to drive the diverter 76 to rotate, so that the semi-arc plate 75 sprays sand particles to remove rust from the inner wall of the pipeline. After rust removal, the inner wall of the pipe body is purged with compressed air to quickly remove a small amount of residual rust, sand, gravel and dust impurities, reduce the purging time, ensure that the inner wall of the pipeline is clean, and the surface is in a frosted state, which increases adhesion and facilitates glazing of the inner wall; Step 3: Pipe heating and glaze deposition: After the inner wall of the pipe is treated, the pipe is heated by medium frequency heating, and then the glaze is sprayed and deposited on the inner wall of the steel pipe to form a bright and dense glass glaze layer, which makes the pipe have the properties of high temperature resistance, corrosion resistance, wear resistance and anti-fouling wax deposition; Step 4: Pipe cooling and finished product inspection: After glazing is completed, it is naturally cooled, and then the three indicators of the pipe glaze layer appearance quality, thickness, and leakage points are inspected before delivery. The appearance is smooth, the color is uniform, there are no visible bubbles or cracks, and the thickness of the pipe is greater than or equal to 500 microns. Then, electric spark detection is used to detect leakage points. Only after meeting the standards can it be shipped out of the factory.

[0037] The complete usage steps and working principle of the above embodiment are as follows: When in use, first rotate the threaded rod 67 to drive the boss slider 611 to move, and then the boss slider 611 drives the long slot plate 610 to move. Since the long slot plate 610 is fixedly connected to the limiting rod 613 on one side, and a long slot is provided on the surface of the long slot plate 610, the long slot plate 610 will slide along the first arc groove 612 with the limiting rod 613, so that the annular turntable 618 rotates. Then, because the L-shaped rod 69 is slidably connected to the second arc groove 619 of the annular turntable 618, if the annular turntable 618 rotates clockwise, it will push the L-shaped rod 69 and the walking wheel 62 to extend outward. If the annular turntable 618 rotates counterclockwise, it will pull the L-shaped rod 69 and the walking wheel 62 to retract inward, thereby achieving the effect of adjusting the distance of the L-shaped rod 69 according to the size of the pipeline, ensuring that the walking wheel 62 can move on the inner wall of the pipeline, and multiple L-shaped rods 69 can be adjusted at one time, which is simple to operate.

[0038] Furthermore, after adjusting the distance of the L-shaped rod 69, the driving member 3, the supporting ring frame 61 and the connecting sleeve 4 can be pushed into the pipe in sequence. After the pipe reaches the position at the other end, the reverse sandblasting and rust removal operation can be performed. When the supporting ring frame 61 is pushed into the inner wall of the pipe, the pipe mouth will squeeze the rotating rod 63. According to the size of different pipes, the squeezing force is different. After squeezing, multiple rotating rods 63 are rotated toward the axis of the rotating ring shell 65 at the same time. At this time, the rotating rod 63 will squeeze the telescopic rod 68 to compress the first spring 614. Using the telescopic rod 68 and the column sleeve 615 to sleeve the first spring 614 can effectively prevent the first spring 614 from being bent and effectively support the rotating rod 63. Then, when the rotating plate 66 enters the inner wall of the pipe, the staff needs to assist in checking whether the wood fiber wiping block 616 and the arc edge scraper 617 are facing the inner wall of the pipe, so as to facilitate effective work, and when the first spring 614 Under the action of elastic force, the wood fiber wiping block 616 and the arc edge scraper 617 will always fit the inner wall after entering the pipeline. Then, when the equipment is continuously pushed deeper into the pipeline, since the walking wheel 62 is always in contact with the inner wall of the pipeline, the walking wheel 62 will spirally walk on the inner wall of the pipeline. The multiple walking wheels 62 will drive the supporting ring frame 61 and the rotating ring shell 65 to rotate as a whole. The rotation of the supporting ring frame 61 will drive the rotating rod 63 and the rotating plate 66 to rotate synchronously. The walking wheels 62 and the rotating plate 66 are both inclined at a certain angle, and the wood fiber wiping block 616 and the arc edge scraper 617 are always in contact with the inner wall. Therefore, the wood fiber wiping block 616 and the arc edge scraper 617 will also spirally walk on the inner wall of the pipeline. The wood fiber wiping block 616 can wipe off the oil stains in the pipeline, and the arc edge scraper 617 can flatten the residual protrusions on the inner wall, which is conducive to the neatness and uniformity of the inner wall of the pipeline during sandblasting, and improves the quality of the product after sandblasting. Please refer to the above working process Figures 1 to 7 .

[0039] Furthermore, when the rust remover is pushed deeper into the pipeline, the first thing to enter the pipeline is the collection box 71. Here, the staff also needs to assist in pressing the collection box 71 and compressing the second spring 713 so that the collection box 71 can adapt to the inner wall of pipelines of different sizes. When the pipeline reaches the position at the other end of the pipeline, the staff can start the driving member 3 to drive the rotating shaft 78 to rotate, start the external ventilation equipment, and the air flow enters the air connection pipe 5, and finally blows the sand into the diverter 76, and then the diverter 76 guides the air flow and the sand to the two nozzles 77 respectively, and then passes through the nozzles 77 to The inner wall of the pipe is sandblasted, and the nozzle 77 is set to be flat and expanded outward, and the edge cut is parallel to the rotating shaft 78, which can increase the spray range of sand particles on the inner wall of the pipe per unit time and improve the sandblasting speed. The semi-arc plates 75 set at the top or bottom of the two nozzles 77 can reduce the airflow resistance when the nozzles 77 rotate on the one hand, and the semi-arc plates 75 can also assist the nozzles 77 to rotate due to their own gravity. The nozzles 77 are easy to rotate and can save energy consumption. At the same time, during the rotation of the rotating shaft 78, the telescopic block 711 will be driven to continuously rotate in the circle at the top of the swing sleeve 73. The locking cam 714 is pressed against the locking cam 716 and the locking cam 73 is pressed against the locking cam 717 to release the locking cam 716. The locking cam 716 is pressed against the locking cam 717 and the locking cam 73 is pressed against the locking cam 716. The reciprocating swing at the entrance of the collection box 71 can effectively break up the accumulated residues and rust, facilitate collection, and prevent the collection box 71 from being stuck. When the rotating shaft 78 is rotated quickly for the sandblasting effect, the telescopic block 711 has insufficient rebound time for the third spring 715 due to the fast rotation speed, so that the extrusion force of the telescopic block 711 on the fixed block 714 is small, and only the swing sleeve 73 vibrates slightly. The collection box 71 and the material-dispensing plate 79 can also be vibrated synchronously to collect materials. After the sandblasting is completed, the rust remover can automatically collect some residues and rust, reducing the next step of purging time; Please refer to the above working process Figure 1 , Figures 8 to 10 .

10. A method for processing a glass glaze anti-corrosion pipeline for oil mining, applied to a metal rust remover for a glass glaze anti-corrosion pipeline for oil mining as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Pipe end cladding and groove processing: Build up welding at the pipe end to form a welding joint, and the cladding layer is complete without weld nodules or welding slag. Then use an automatic lathe to automate the pipe groove processing. The groove end face should be flush and free of burr defects to facilitate on-site welding construction; Step 2: Rust removal and dust removal on the inner wall of the pipeline: After the processing of the pipeline port is completed, the inner wall of the pipeline is first subjected to sandblasting pre-treatment to ensure that the pipeline is sandblasted and rust-removed. Then, a rust removal machine is used to sandblast and remove rust, and the quality reaches Sa3.0 level requirements. Air is introduced through the air pipe (5), and sand is introduced into the pipe rack (1). Then, the driving member (3) is used to drive the diverter (76) to rotate, so that the semi-arc plate (75) sprays sand to remove rust from the inner wall of the pipeline. After rust removal, compressed air is used to blow the inner wall of the pipe body to quickly remove a small amount of residual rust, sand, gravel and dust impurities, thereby reducing the blowing time, ensuring that the inner wall of the pipeline is clean, and the surface is in a frosted state, which increases adhesion and facilitates glazing of the inner wall; Step 3: Pipe heating and glaze deposition: After the inner wall of the pipe is treated, the pipe is heated by medium frequency heating, and then the glaze is sprayed and deposited on the inner wall of the steel pipe to form a bright and dense glass glaze layer, which makes the pipe have the properties of high temperature resistance, corrosion resistance, wear resistance and anti-fouling wax deposition; Step 4: Pipe cooling and finished product inspection: After glazing is completed, it is naturally cooled, and then the three indicators of the pipe glaze layer appearance quality, thickness, and leakage points are inspected before delivery. The appearance is smooth, the color is uniform, there are no visible bubbles or cracks, and the thickness of the pipe is greater than or equal to 500 microns. Then, electric spark detection is used to detect leakage points. Only after meeting the standards can it be shipped out of the factory.
