Description

Technical Field

[0001] This invention relates to a steel pipe processing equipment, and more particularly to a stainless steel seamless pipe cleaning equipment. Background Technology

[0002] Stainless steel seamless pipe is a long strip of steel with a hollow cross-section and no seams around its perimeter. It is resistant to corrosion from weak corrosive media such as air, steam, and water, as well as chemical corrosive media such as acids, alkalis, and salts; it is also known as stainless acid-resistant steel pipe. The processing flow of stainless steel seamless pipe includes multiple cleaning steps, including cleaning the outer circumference of the stainless steel seamless pipe after processing and polishing. Through continuous research and development by those skilled in the art, the cleaning process for steel pipes has gradually evolved from manual cleaning to mechanical cleaning. However, existing cleaning equipment cannot be adapted to different pipe diameters, or requires adjustments to the equipment before cleaning based on the different pipe diameters to achieve the desired cleaning effect. This results in extremely low cleaning efficiency, making it difficult to meet the future development needs of enterprises. Summary of the Invention

[0003] The purpose of this invention is to provide a stainless steel seamless pipe cleaning equipment that can automatically adapt to the cleaning of steel pipes of different diameters, thereby improving cleaning efficiency and meeting the future development needs of enterprises.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a stainless steel seamless pipe cleaning device, comprising a cleaning tank with an upward opening, wherein two opposite side walls of the cleaning tank are provided with docking components, two docking components cooperate to fix steel pipes, each set of docking components is provided with a driving component, the driving component drives the steel pipe to rotate circumferentially on the docking component, an adjusting component is provided on one side of each set of docking components, the adjusting component abuts against the outer peripheral wall of the steel pipe on the docking component and has a tendency to move towards the center of the steel pipe, a cleaning spray pipe that moves with the adjusting component is connected between the two sets of adjusting components, the cleaning spray pipe is located on the outside of the steel pipe on the docking component and has a plurality of spray holes distributed in a position facing the steel pipe.

[0005] By adopting the above technical solution, the steel pipe to be cleaned is transported to the top of the cleaning tank and fixed by two sets of docking components. The adjusting component tends to move towards the center of the steel pipe, thus automatically driving the cleaning nozzle to move towards the steel pipe and bring it close to the outer periphery of the pipe. Then, the driving component drives the steel pipe to rotate circumferentially on the docking components, ensuring that the water jet from the cleaning nozzle evenly and comprehensively covers the outer periphery of the steel pipe, thereby achieving the cleaning purpose. The wastewater generated during cleaning falls into the cleaning tank, preventing pollution. The adjusting component's tendency to move towards the center of the steel pipe automatically adjusts the distance between the cleaning nozzle and the outer periphery of steel pipes of different diameters, adapting to the cleaning of different diameter steel pipes, improving cleaning efficiency, and thus meeting the future development needs of enterprises.

[0006] The configuration is further defined as follows: the two sets of adjustment components are located below the two sets of docking components, and when the steel pipe is installed with the docking components, the two sets of adjustment components are located directly below the steel pipe.

[0007] By adopting the above technical solution, this setting allows the steel pipe installed on the docking assembly to exert gravity on the adjusting assembly. In conjunction with the tendency of the adjusting assembly to move towards the center of the steel pipe, the cleaning nozzle is always positioned close to the steel pipe and located on the outer side of the outer circumference of the steel pipe. This achieves automatic adjustment to adapt to the cleaning of steel pipes of different diameters, resulting in higher efficiency, better cleaning quality, and the ability to work with the docking assembly to support the steel pipe, making the structure more stable.

[0008] The configuration is further set such that the two sets of drive components are located between the two sets of docking components, such that when the steel pipe is installed on the docking components, the two sets of drive components are located on the inner ring of the steel pipe, and the distance between the two sets of adjustment components is less than the distance between the two drive components.

[0009] By adopting the above technical solution, when the steel pipe is installed on the docking assembly, the two sets of drive components are located in the inner ring of the steel pipe. The steel pipe isolates the drive components from the outside world, preventing water flow during the cleaning process from contacting the drive source on the drive components and causing short circuits or damage, thereby ensuring that the drive components are in a safe working environment.

[0010] The assembly is further configured such that each docking component includes a docking telescopic arm, a docking drive component for driving the docking telescopic arm, at least one docking wheel rotatably disposed on the docking telescopic arm and abutting against the inner circumferential wall of the steel pipe, and a limiting wheel rotatably disposed on the docking telescopic arm and abutting against the end face of the steel pipe, and the two docking telescopic arms reciprocate relative to each other.

[0011] By adopting the above technical solution, the steel pipe to be cleaned is transported between the two docking components. The docking drive drives the two docking telescopic arms to move towards each other so that the docking wheel enters the inner ring of the steel pipe and the limit wheel abuts against the end face of the steel pipe. Then the steel pipe is released, and the steel pipe is placed on top of the docking wheel under the action of gravity. This completes the docking and rotation operation of the steel pipe on the docking component and ensures the stability of the steel pipe during rotation.

[0012] The further configuration is as follows: the number of docking wheels is two and an installation gap is formed between the two docking wheels; the limiting wheel is rotatably set at the installation gap and located on the side of the docking wheel near the side wall of the cleaning tank; the axis of the limiting wheel is vertically set and perpendicular to the axis of the docking wheel; the limiting wheel extends along its axis to form a long strip.

[0013] By adopting the above technical solution, the two docking wheels can provide more stable support for the steel pipe, and the installation gap formed between the two wheels can be used in conjunction with the long strip-shaped limiting wheel to ensure that the end faces of steel pipes of different diameters and thicknesses placed on the two docking wheels can stably abut against the limiting wheel, thereby ensuring the stable rotation of the steel pipe on the docking assembly.

[0014] The drive assembly is further configured to include a drive motor mounted on the docking telescopic arm, a transmission wheel that rotates with the docking wheel, and a transmission belt that links the transmission wheel and the drive motor.

[0015] By adopting the above technical solution, the drive motor drives the docking wheel to rotate through the transmission belt and the transmission wheel, thereby realizing the circumferential rotation of the steel pipe on the docking assembly.

[0016] The adjustment assembly is further configured as follows: the adjustment arm is slidably disposed on the docking telescopic arm, the receiving plate is fixedly disposed on the adjustment arm and abuts against the outer peripheral wall of the steel pipe, and the clamping spring is used to drive the adjustment arm to move the receiving plate toward one side of the steel pipe.

[0017] By adopting the above technical solution, the steel pipe fixed on the docking assembly abuts against the top of the receiving plate. Under the action of the clamping spring, the cleaning nozzle is located outside the steel pipe and close to the outer peripheral wall of the steel pipe, so as to adapt to the cleaning operation of steel pipes of different diameters and realize automatic control.

[0018] The further configuration is as follows: the bottom of the cleaning tank is recessed downward to form a guide surface, the lowest position of the guide surface forms an extrusion groove, an extrusion screw is rotatably arranged inside the extrusion groove, a first motor is provided outside the cleaning tank to drive the extrusion screw to rotate, a discharge groove is provided at the extrusion end of the extrusion groove to connect the extrusion groove with the outside, and an opening and closing component is provided on the discharge groove.

[0019] By adopting the above technical solution, the polishing sludge generated during cleaning settles to the bottom of the cleaning tank under the action of gravity, and enters the extrusion tank under the guidance of the guide surface. The first motor drives the extrusion screw to rotate, pushing the sludge in the extrusion tank toward the discharge tank. With the help of the set opening and closing components, the sludge is discharged. The rotating extrusion screw can also squeeze the water in the sludge, realizing the discharge after solid-liquid separation. It has both extrusion and compression functions, which is more practical and convenient for subsequent environmental protection treatment.

[0020] The opening and closing assembly is further configured to include a cover hinged to the cleaning tank, a torsion spring that drives the cover to close the discharge tank port, and a sealing ring disposed between the cover and the discharge tank port.

[0021] By adopting the above technical solution, the force of the torsion spring is less than the driving force of the first motor but greater than the pressure of the liquid in the cleaning tank. This arrangement allows the sludge to gradually enter and accumulate in the discharge tank under the action of the extrusion screw. The sludge gradually accumulating in the discharge tank compresses against each other, expelling the moisture contained in the sludge through the gap between the extrusion screw and the discharge tank, resulting in a sludge content greater than the moisture content and a semi-dry state in the discharge tank. When the pressure of the accumulated sludge exceeds the force of the torsion spring, the cover automatically opens to discharge the semi-dry sludge; when the sludge pressure is less than the force of the torsion spring, it automatically closes. This discharge structure enables automatic discharge of sludge without causing large-area leakage of liquid in the cleaning tank, offering better practicality and automatic discharge opening and closing.

[0022] The further configuration is as follows: a plurality of rollers that abut against the steel pipe are rotatably arranged on the receiving plate.

[0023] By adopting the above technical solution, the roller design reduces the wear on the outer wall of the steel pipe and ensures the quality of the steel pipe.

[0024] In summary, the present invention has the following beneficial effects: the present invention can automatically adapt to the cleaning of steel pipes of different diameters, thereby improving cleaning efficiency and meeting the future development needs of enterprises.
