[0002] The pickling process uses an acidic solution to remove the oxide layer and rust on the surface of steel. After pickling, passivation is formed on the surface of the steel to improve the corrosion resistance of the steel.

At present, many enterprises still widely adopt the production method of manually applying pickling and passivation paste to the metal pipe body with a brush. Especially when applying it to the inside of metal pipe fittings, workers need to drill in to apply it manually. For products with very small inner holes or complex inner part structures, pickling and passivation are very difficult to implement. After pickling and passivation, the residual pickling and passivation paste is flushed away with water. The traditional process of applying pickling and passivation paste is obsolete, with poor application effect, high labor intensity, harsh working environment, time-consuming and laborious, and the flushing effect is not good.

Detailed Embodiment

[0050] For the convenience of those skilled in the art to understand, the present utility model will be further described below with reference to the drawings.

[0051] Please refer to Figure 1 , which is an embodiment of a pickling and passivation device provided by the present utility model, including an operating mechanism, a paste conveying mechanism, and a cleaning liquid conveying mechanism. The operating mechanism includes a first housing 3 and a second housing 9. One end of the second housing 9 is connected to the first housing 3 through an angle adjustment mechanism, and an operating head 11 is fixed at the other end. The paste conveying mechanism includes a paste conveying pipe 6 and a paste pumping assembly. The cleaning liquid conveying mechanism includes a flushing pipe 5 and a cleaning liquid pumping assembly. During use, the cleaning liquid pumping assembly pumps the cleaning liquid into the flushing pipe 5, and the paste pumping assembly pumps the pickling and passivation paste into the paste conveying pipe 6. The pickling and passivation paste and the cleaning liquid are respectively conveyed to the operating head 11 through the paste conveying pipe 6 and the flushing pipe 5. The operating head 11 is controlled to apply the pickling and passivation paste to the inner wall of the pipeline or spray the cleaning liquid onto the inner wall of the pipeline to remove the pickling and passivation paste, and finally complete the pickling and passivation treatment of the pipeline. Due to the setting of the angle adjustment mechanism, the operating head 11 is allowed to perform pickling and passivation treatment on different positions and angles of the pipeline.

[0052] The paste pumping assembly includes a paste storage bin 1, a conveying disk 2, and a paste extrusion element 20. The paste storage bin 1 can be separately arranged from the first housing 3. Preferably, the paste storage bin 1 is installed in the first housing 3. The paste storage bin 1 has a cylindrical inner cavity, and the conveying disk 2 is slidably arranged in the inner cavity. The conveying disk 2 divides the inner cavity into a paste storage chamber and a gas chamber, and the paste extrusion element 20 is used to push the conveying disk 2 towards the paste storage chamber side. The paste storage chamber is used to temporarily store the pickling and passivation paste, and the gas chamber provides space for the connection of the paste extrusion element 20. For the space sizes of the paste storage chamber and the gas chamber, they change during use. As the pickling and passivation paste flows out of the paste storage chamber, the volume of the paste storage chamber becomes smaller, and the volume of the corresponding gas chamber increases until the pickling and passivation paste in the paste storage chamber is completely extruded. The conveying disk 2 is made of rubber material, and its outer diameter is the same as the inner diameter of the paste storage bin 1. It can freely move back and forth in the inner cavity and can form a sliding seal with the inner wall of the paste storage bin 1.

[0053] As an embodiment of the paste extrusion element 20, the paste extrusion element 20 is a piston pump. The housing of the piston pump is detachably connected to the first housing 3, and the air outlet of the piston pump communicates with the gas chamber. When the piston pump inputs gas into the gas chamber, the air in the gas chamber cannot be discharged and thus pushes the conveying disc 2. The conveying disc 2 extrudes the pickling and passivation paste in the paste storage chamber, and conveys the pickling and passivation paste into the paste conveying pipe 6. When the pickling and passivation paste is used up, the paste storage bin 1 can be removed for paste replenishment. As the paste in the paste storage chamber gradually increases, the extrusion conveying disc 2 moves to the right, the volume of the gas chamber decreases, and the volume of the paste storage chamber increases. The paste extrusion element 20 can also use a cylinder, and the piston rod of the cylinder is directly connected to the conveying disc 2 to push the conveying disc 2 to move toward the paste storage chamber side. The paste extrusion element 20 can also adopt elements such as an electric telescopic rod and a lead screw, as long as it can drive the conveying disc 2 to move as required.

[0054] The operation head 11 has a circumferential channel 13 inside, and the circumferential channel 13 is circular. The circumferential channel 13 is provided with a plurality of paste outlets on the end face of the operation head 11 away from the second housing 9. The plurality of paste outlets are distributed in the entire circumference of the circumferential channel 13, preferably evenly distributed. The circumferential channel 13 is provided with a connection port on the end face close to the second housing 9, which is connected to the paste conveying pipe 6 through a joint; the paste can fill the entire circumferential channel 13 and then flow out through the paste outlets. A check valve, such as a diaphragm check valve, is installed on the paste outlet; when the pickling and passivation paste flows toward the paste outlet, the check valve opens, and the pickling and passivation paste flows through the paste outlet; when the pickling and passivation paste flows out of the paste outlet and no longer conveys the pickling and passivation paste to the paste conveying pipe 6, the check valve closes, which can prevent the waste liquid from flowing back and is beneficial to improving the storage environment of the pickling and passivation paste.

[0055] If the cleaning liquid is water, the cleaning liquid pumping component can adopt a water pump and a water tank. The water pump is arranged in the water tank, the input port of the water pump communicates with the water tank, and the output port is connected to the flushing pipe 5; the connection methods of the water pump, the water tank, and the water pump and the flushing pipe 5 are all prior arts, so they are not shown in the drawings and will not be elaborated here. The operation head 11 is also provided with a flushing hole 10. Preferably, the flushing hole 10 is located in the middle of the operation head 11, that is, inside the annularly distributed paste outlets. The flushing hole 10 communicates with the flushing pipe 5, and a pressure-increasing nozzle can be arranged at the output end of the flushing hole 10, and the ejected water flow has a certain pressure to improve the flushing effect. A check valve, such as a diaphragm check valve, is arranged in the flushing hole 10; the cleaning liquid in the flushing hole 10 flows out unidirectionally and does not allow backflow.

[0056] Furthermore, the outer surface of the operation head 11 is covered with bristles 12, and the bristles 12 cover the outer circumferential surface and the end face of the operation head 11 away from the second housing 9; the contact area between the operation head 11 and the surface to be treated is increased, and the smearing or flushing effect is improved.

[0057] Please refer toFigures 2-4 The angle adjustment mechanism includes an upper spherical shell 14, a lower spherical shell 7, a sphere 8 and a locking structure. The upper spherical shell 14 and the lower spherical shell 7 are both connected to the first housing 3. Concave upper spherical cavity 30 and lower spherical cavity 31 are respectively formed on the docking surfaces of the upper spherical shell 14 and the lower spherical shell 7. After the upper spherical cavity 30 and the lower spherical cavity 31 are docked, a spherical adjustment cavity is formed. A connection window is provided on the side of the adjustment cavity away from the first housing 3, and the connection window communicates the adjustment cavity with the outside. The sphere 8 is rotatably arranged in the adjustment cavity and partially extends out of the adjustment cavity through the connection window. The second housing 9 is fixedly connected to the part of the sphere 8 extending out of the connection window. In this way, the angle of the second housing 9 relative to the first housing 3 can be adjusted by rotating the sphere 8. After the adjustment of the sphere 8 is completed, the position of the sphere 8 is fixed by the locking structure.

[0058] The locking structure includes a plurality of card slots 26 and a plurality of claws 29. The card slots 26 are arranged on the sphere 8. The plurality of card slots 26 are evenly distributed on the outer spherical surface of the sphere 8, and the depths and sizes of different card slots 26 are the same. The claws 29 are arranged on the upper spherical shell 14 or the lower spherical shell 7. By using the claws 29 to extend into or leave the corresponding card slots 26, the locking or unlocking of the sphere is realized. The number of claws 29 can be set as required. For example, there are three claws 29, and the three claws 29 cooperate with the card slots 26 on the sphere 8 to fix the position of the sphere 8 after the angle adjustment.

[0059] As an implementation manner of the claw 29, the claw 29 is arranged on the inner wall of the upper spherical cavity 30. The upper spherical shell 14 is rotatably connected to the first housing 3, and the lower spherical shell 7 is fixedly connected to the first housing 3. The upper spherical shell 14 is connected with a driving assembly. In this way, the driving assembly can control the opening or closing of the adjustment cavity. When the adjustment cavity is closed, the claw 29 is caught in a certain card slot 26, thereby limiting the position of the sphere 8 in the adjustment cavity.

[0060] To meet the adjustment requirements, specifically, the upper spherical shell 14 is provided with a first connection hole 22, and the lower spherical shell 7 is provided with a second connection hole 25. The first housing 3 is provided with a U-shaped connection groove, and two groups of through holes are provided on the two groove walls of the connection groove. The positions of the two groups of through holes correspond to the first connection hole 22 and the second connection hole 25 respectively. The lower spherical shell 7 is connected to the lower spherical shell 7 through a bolt located in the second connection hole 25, and the relative position of the lower spherical shell 7 and the first housing 3 is locked by a nut. The upper spherical shell 14 is rotatably connected to the first housing 3 through a pin shaft located in the first connection hole 22.

[0061] The driving component includes a slider 16, a connecting rod 15 and a locking bolt 17. The slider 16 is slidably mounted on the first housing 3; specifically, a sliding table 18 is provided on the outer side surface of the first housing 3, and the slider 16 is slidably mounted on the sliding table 18; the slider 16 slides along the sliding table 18 without slipping off; for example, the cross-section of the sliding table 18 is dovetail-shaped, which can limit the position of the slider 16 in the direction perpendicular to the sliding table 18, and stoppers are provided at both ends of the sliding table 18. The locking bolt 17 is threadedly connected to the slider 16 and is used to lock the position of the slider 16; when it is necessary to lock the slider 16, rotate the locking bolt 17 to make it press tightly against the sliding table 18 or the first housing 3. A connecting plate 21 is provided on the outer side wall of the upper spherical housing 14, and both ends of the connecting rod 15 are hinged to the slider 16 and the connecting plate 21 respectively. When the slider 16 is operated to slide in a direction away from the upper spherical housing 14, the upper spherical housing 14 rotates clockwise around the pin shaft. After the upper spherical housing 14 is opened, the claw 29 and the card slot 26 are separated, and the sphere 8 can rotate freely, thereby driving the second housing 9 to rotate and adjust the angle, and the operating head 11 can better apply the pickling and passivation paste; after the adjustment of the sphere 8 is completed, push the slider 16 close to the upper spherical housing 14, and the upper spherical housing 14 rotates counterclockwise to close, and the claw 29 is snapped into the card slot 26 to complete the fixation, avoiding the angle change of the second housing 9 during the pickling and passivation operation.

[0062] Among them, a first paste channel 19 and a first flushing channel 4 are provided in the first housing 3; the paste delivery pipe 6 is located in the first paste channel 19, and the flushing pipe 5 is located in the first flushing channel 4. A second paste channel 23 is provided in the upper spherical housing 14, and the second paste channel 23 communicates with the upper spherical cavity 30; a second flushing channel 24 is provided in the lower spherical housing 7, and the second flushing channel 24 communicates with the lower spherical cavity 31. A third paste channel 27 and a third flushing channel 28 are provided in the sphere 8; after the paste delivery pipe 6 sequentially passes through the first paste channel 19, the second paste channel 23 and the third paste channel 27, it communicates with the circumferential channel 13; the flushing pipe 5 sequentially passes through the first flushing channel 4, the second flushing channel 24 and the third flushing channel 28 and then communicates with the flushing hole 10. The paste delivery pipe 6 and the flushing pipe 5 are both located inside the device and are not exposed outside, and the overall structure of the pickling and passivation device is simple and convenient to use.

[0063] The ends of the third paste channel 27 and the third flushing channel 28 are trumpet-shaped, and the large ends face outwards; this allows the paste delivery pipe 6 and the flushing pipe 5 located therein to still be able to transport normally when the sphere 8 rotates without getting stuck.

[0064] In order to adapt to the rotation adjustment of the sphere 8, at least the paste delivery pipe 6 and the flushing pipe 5 corresponding to the sphere 8 are flexible straight pipes. Preferably, the whole is a flexible hose, which can better adapt to the adjustment action of the angle adjustment mechanism. The inner surface of the flexible straight pipe is coated with polytetrafluoroethylene (modified ETFE) to form a polytetrafluoroethylene layer; the paste delivery pipe 6 and the flushing pipe 5 have characteristics such as drug resistance, non-dissolution, non-adhesion, and less peculiar smell. The inner surface with excellent non-adhesion property makes it difficult for fluids to remain, the inner surface is not easily soiled, and the cleaning is simple.

[0065] An endoscope can also be installed on the operation head 11 or the second housing 9. When the pipe diameter is small, the internal structure is numerous or complex, and it is impossible or difficult for workers to enter the container for operation, the internal smearing and cleaning conditions of the container can be clearly observed through the endoscope. The structure of the endoscope is prior art, and an existing endoscope on the procurement market is purchased and used; the structure of the endoscope is not improved in this application.

[0066] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications.
