Description

Technical Field

[0001] The invention relates to the technical field of pipe recycling, and in particular to a surface treatment device and method for pipe recycling. Background Art

[0002] In terms of the reuse of old pipes, it is usually necessary to grind the surface of the pipe to remove rust and dirt on the surface and restore its original appearance and mechanical properties. However, the outer diameter of the old pipes often has a certain tolerance, which means that the diameters of the pipes in the same batch are not exactly the same. The size of the conventional grinding disc or scraper is usually fixed, and the spacing between the pipes remains unchanged. Due to the tolerance of the outer diameter of the pipe, the fixed grinding disc or scraper cannot perfectly match all pipes, resulting in uneven grinding. In some places where the rust on the surface of some pipes is thinner, the grinding may not be thorough. In order to ensure the smooth outer wall of the pipe, the operator needs to adjust the position of the grinding milling cutter several times, which may lead to over-grinding, resulting in a significant reduction in the wall thickness of the pipe, affecting its structural strength and reuse value. Summary of the invention

S3. Start the pneumatic clamp to fix the pipe, shrink it and firmly clamp the pipe; adjust the telescopic spacing of the pneumatic clamp inside the fixed vertical beam to be slightly smaller than the telescopic spacing of the pneumatic clamp inside the movable vertical beam; S4, start the grinding process. Turn on the power supply of the electromagnet to generate repulsion between it and the permanent magnet, and push the positioning plate to move horizontally along the longitudinal slide groove of the guide support plate. At this time, the grinding plate contacts the surface of the pipe and starts grinding. Parameter setting, the electromagnet voltage is 220V, the conventional current is 2A (adaptively adjustable according to the outer diameter of the pipe), and the distance between the permanent magnet and the pipe is maintained at 0.5-1mm; S5. Adjust the fit of the grinding plate. According to the outer diameter tolerance of the pipe, adjust the power of the electromagnet in real time to control the repulsive force of the permanent magnet, so as to ensure the fit between the grinding plate and the pipe; S6. Cooling and cleaning Start the water pump to spray the water in the water tank to the contact end of the grinding plate and the pipe through the diverter plate and the cooling nozzle to cool and clean the grinding area; Parameter settings: water pump flow rate is 10L / min, pressure is 0.2MPa; S7.

If the inclined surface of the grinding plate is flattened, replace the grinding plate in time. S8, end of grinding process After grinding is completed, turn off the power supply of the electromagnet to restore the positioning plate to its original position; then, close the pneumatic clamp and take out the processed pipe; S9. Cleaning and maintenance Clean the equipment, check and maintain each component to ensure the normal operation of the equipment As the preferred technical solution of the present invention, the old pipes are movably installed inside the movable vertical beam and the fixed vertical beam and move horizontally and parallelly with the center point of the frame. The telescopic movable spacing of the pneumatic clamp inside the fixed vertical beam is smaller than the telescopic movable spacing of the pneumatic clamp inside the movable vertical beam, and the fixed vertical beam is movably connected to the old pipes.

[0005] Using the above technical solution, four pneumatic clamps are fixed inside the vertical beam, and only the pneumatic clamp on the bottom surface is at the same height as the pneumatic clamp at the bottom of the movable vertical beam. The pneumatic clamps on the left and right sides of the fixed vertical beam, including the top, are spaced 1 mm from the old pipe, ensuring that the pipe can be angled inside the fixed vertical beam while still having a certain sliding space to reduce the friction of horizontal movement.

[0006] As a preferred technical solution of the present invention, a transverse slide groove is arranged inside the positioning plate, a slide rail is arranged inside the transverse slide groove, the transverse slide groove slides with the grinding plate through the slide rail, a connecting plate is symmetrically arranged on the outer surface of one end of the grinding plate, bolts are arranged inside the connecting plate and the grinding plate is fixed inside the positioning plate through the bolts.

[0007] With the above technical solution, the grinding plate is a consumable part. In order to ensure the grinding effect, when one end of the grinding plate is worn too much, the grinding plate can be replaced by disassembly. The surface of the grinding plate becomes thinner with grinding, and the grinding plate and the pipe are kept in contact by electromagnetic telescopic means, so that the grinding plate can be fully utilized and replaced after the inclined surface of the grinding plate is smoothed.

[0008] As a preferred technical solution of the present invention, the number of the electromagnets and the number of the permanent magnets are four respectively, and the electromagnets and the permanent magnets are magnetically connected as a power source for the parallel sliding of the positioning plate.

After the electromagnet is energized, it moves horizontally with the permanent magnet through repulsion, and the permanent magnet controls the repulsion of the permanent magnet by the power of the electromagnet, thereby controlling the fit between the grinding plate and the pipe. Even if there is a tolerance in the outer diameter of the pipe, the grinding plate always keeps fit with the pipe under the action of the repulsion of the magnet. Even if the distance between the grinding plate and the pipe at the left and right ends is different, the repulsion will gradually decrease as the grinding moves forward, thereby ensuring that the curvature of the inner and outer edges of the pipe is the same, and the thickness of the pipe can also be symmetrical accordingly.

[0011] By adopting the above technical scheme, the heat conduction plate contacts the pipe through the water absorbent block and can absorb the moisture on the surface of the pipe. The heat conduction plate conducts the heat generated by the electromagnetic operation of the electromagnet and the permanent magnet, and heats the water absorbent block on the outer surface to evaporate the moisture inside the water absorbent block, thereby ensuring the dewatering effect and wiping off the grinding debris on the surface of the pipe. The water absorbent block is detachable for easy replacement, and the distance between the heat conduction plate and the pipe is smaller than the distance between the positioning plate and the pipe. The water absorbent block made of flexible material is used to fill the distance difference between the two to avoid surface scratches caused by friction between the pipe and the heat conduction plate after grinding, so as to facilitate rapid cooling of the pipe after grinding.

[0012] As the preferred technical solution of the present invention, an upper pressure plate is arranged at the top of the frame, a vertical screw is movably connected to the middle end of the upper pressure plate, the vertical screw is threadedly connected to the frame, and vertical guide rods are symmetrically arranged on the bottom surface of the upper pressure plate to slide with the frame.

[0013] By adopting the above technical solution, the upper pressure plate is transmitted through the vertical screw and the frame thread, and one end of the vertical screw lifts the vertical height of the upper pressure plate. The upper pressure plate can support the pipe and adapt to pipes of different outer diameters by changing the vertical height.

[0014] As the preferred technical solution of the present invention, a lower support plate is provided at the bottom end of the beam, and the lower support plate has the same structure as the upper pressure plate. A vertical screw is provided at one end of the vertical screw. The vertical screw of the turntable lower support plate is threadedly connected to the beam, and the vertical guide rod of the lower support plate is slidably matched with the beam. The upper pressure plate and the lower support plate are movably connected internally with balls for supporting the old pipe.

[0015] By adopting the above technical solution, balls are respectively provided at the ends of the lower support plate and the upper pressure plate that contact the pipe to reduce the friction with the pipe. The upper push and lower pressure method can limit the angle of the pipe, so that the pipe can be kept horizontally placed, avoiding axial tolerance during rotation, thereby ensuring stability during pipe processing.

[0016] As the preferred technical solution of the present invention, a guide groove is arranged at the top of the frame, a screen is arranged inside the guide groove to block foreign matter, and a sewage tank is arranged at the bottom end of the base plate, the interior of the sewage tank is a hollow structure and is interconnected with the guide groove.

[0017] By adopting the above technical solution, the diversion trough can divert and recycle the cooling water, and the screen can prevent oversized debris from entering the sewage tank. The sewage inside the sewage tank can be purified and reused by setting a conduit, and the metal debris mixed inside can be removed after sedimentation.

[0018] As a preferred technical solution of the present invention, a water pump is arranged at the top of the water tank, the output end of the water pump is connected to the inside of the water tank, one end of the water pump is connected to a hose, the other end of the hose is connected to a diverter plate, cooling nozzles are evenly distributed inside the diverter plate, and the output end of the cooling nozzle is inclined toward one end of the grinding plate.

[0019] By adopting the above technical solution, a water pump draws water into the water tank and uses positive pressure to spray water out from the inside of the cooling nozzle from the diverter plate, and the cooling nozzle is aimed at the grinding plate to ensure that metal splashes generated during the friction between the grinding plate and the pipe are eliminated, while cooling and cleaning the contact end of the grinding plate and the pipe.

[0020] As a preferred technical solution of the present invention, a drive box is provided at the top of the movable vertical beam, and the drive box includes a motor, a driving gear and a driven gear. The driving gear is connected to the output end of the motor, the driving gear is meshed with the driven gear, and the driven gear is fixedly connected to the pipe bearing sleeve of the movable vertical beam.

[0021] By adopting the above technical solution, the driving mechanism provided in the driving box drives the pipe bearing sleeve, so that the pipe inside the pipe bearing sleeve is in a high-speed rotating state, and the pipe and the positioning plate are in a static and dynamic manner to improve the stability during the grinding process.

[0022] Compared with the prior art, the surface treatment device and treatment method for pipe recycling of the present invention have the following beneficial effects: The adjustable electromagnetic connection and positioning plate design can adapt to pipes of different outer diameters, avoiding the limitations of traditional fixed grinding discs or scrapers, thereby achieving uniform grinding and improving the quality of surface treatment. The magnetic connection between the electromagnet and the permanent magnet realizes the precise movement of the positioning plate, reducing the time and labor intensity of manual adjustment, improving processing efficiency, allowing the pipe to have a certain sliding space inside the fixed vertical beam, and at the same time being able to limit the angle, reducing the friction during the grinding process, reducing the risk of over-grinding, thereby protecting the structural strength and reuse value of the pipe. Through the synergistic effect of the water pump and the cooling nozzle, not only can the grinding area be cooled to prevent the pipe from overheating, but also the metal splashes and debris generated during the grinding process can be cleaned, ensuring a clean working environment.
