Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, and in particular to a metal surface treatment device with efficient rust removal function. Background Technology

[0002] Metal materials are widely used in various fields. However, during storage and use, the surface of metal is easily affected by oxidation, corrosion and other factors, which can cause rust. This not only reduces the appearance of the metal, but also seriously affects its performance and service life. Therefore, rust removal treatment of metal surfaces has become a crucial step in the metal processing process.

[0003] For example, CN212122935U discloses a high-efficiency water blasting rust removal device, which includes a base plate, a high-pressure water pump fixedly installed on the top of the base plate, an inlet hose fixedly installed at the inlet end of the high-pressure water pump, a counterweight filter fixedly connected to the end of the inlet hose away from the high-pressure water pump, and an outlet hose fixedly installed at the outlet end of the high-pressure water pump.

[0004] This patent removes rust by impacting the surface of an object with high-speed jets of sand. Although sandblasting is relatively efficient, it has many drawbacks. On the one hand, the sandblasting process generates a large amount of dust, which causes serious environmental pollution and the dust can easily enter the respiratory system of operators, harming their health. On the other hand, improper control of the sandblasting force can easily cause excessive damage to the metal surface, affecting the surface quality and subsequent performance of the metal. In addition, the maintenance cost of sandblasting equipment is high, requiring regular replacement of sand and maintenance of the equipment. Therefore, we propose a metal surface treatment device with efficient rust removal function. Utility Model Content

[0035] In this embodiment, the spraying assembly 59 includes a connecting box 592. A rust-removing cover 591 is fixedly connected to the lower end of the connecting box 592. A plurality of first rust-removing spray heads 593 are fixedly connected to the lower end of the connecting box 592. A plurality of second rust-removing spray heads 596 are fixedly connected to the outer surface of the rust-removing cover 591. One end of each second rust-removing spray head 596 is fixedly connected to a diversion bend 594. A diversion valve 595 is provided at one end of the diversion bend 594 near the rust-removing cover 591. The other end of the diversion bend 594 is fixedly connected to the upper end of the connecting box 592. The rust-removing cover 591 is fixedly connected to the telescopic tube 57. Next, multiple first rust-removing spray heads 593 are evenly distributed in a ring around the connecting box 592, and multiple second rust-removing spray heads 596 are equally distributed in a ring around the rust-removing cover 591.

[0037] It should be noted that this utility model is a metal surface treatment device with efficient rust removal function. First, open the box door 1, place the metal to be rusted on the support hollow plate 6, close the box door 1, and start the device through the control module 4. The electric push rod 51 drives the connecting block 54 and the limiting block 58 to move longitudinally along the limiting groove 23, so that the spraying component 59 descends to the appropriate position. At this time, the rust removal liquid in the first rust removal liquid box 52 and the second rust removal liquid box 53 enters the connecting box 592 through the delivery pipe 55, the first control valve 56, and the telescopic pipe 57. A part of the rust removal liquid is sprayed through multiple first rust removal spray heads 593 that are evenly distributed in a ring and have vertically downward nozzles. On the upper surface of the metal, another part is sprayed onto the side and lower surface of the metal through a series of second rust removal spray heads 596 arranged in a ring and equidistantly, with the nozzles at a 15° angle to the vertical direction via a diversion bend 594 and a diversion valve 595. Waste liquid and impurities generated during the rust removal process fall into the groove 25 through the support hollow plate 6. After being filtered by the filter screen 24 and the fine filter screen 26, they can be returned to the second rust removal liquid box 53 for recycling through the circulation pipe 510 and the second switch valve 511. After the rust removal is completed, the relevant valves are closed and the blower equipment 27 is started to air dry the treated metal surface. The air drying process can be observed through the observation cover 3. If maintenance is required, the maintenance door 22 can be opened.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
