Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel processing, in particular to a phosphorus washing system for steel. Background Art
[0002] During the processing of steel, the surface of the steel needs to be phosphated. Phosphating is a commonly used pre-treatment technology for steel processing. In principle, it should belong to chemical conversion film treatment. Phosphating is a process in which a phosphate chemical conversion film is formed by chemical and electrochemical reactions. The phosphate conversion film formed is called a phosphate film. The purpose of phosphating is mainly to provide protection for the base metal and prevent the metal from being corroded to a certain extent; it is used as a primer before painting to improve the adhesion and corrosion resistance of the paint film; it plays a role in reducing friction and lubrication in the metal cold processing process, and the discarded steel needs to remove the phosphate film on the surface.
[0003] In most existing steel processing processes, phosphorus removal is achieved by immersing the steel in an acidic solution. Phosphates react with the acidic solution to form water-soluble phosphates, thereby achieving dephosphorization. However, this method is particularly effective for tubular steel. Over time, large amounts of phosphates tend to accumulate at the bottom of the phosphorus washing tank, making it difficult to clean. Furthermore, the tubular steel needs to be suspended, resulting in low efficiency and high costs. Therefore, a phosphorus washing system for steel is needed to address these issues.

Then the movable frame is driven from front to back, and the remaining plurality of connecting pipes transport clean water to the nozzle position to flush the surface of the tubular steel material after phosphorus washing.

[0014] Furthermore, a plurality of support seats are fixedly connected at equal intervals to the middle portion of the upper end of the base frame;
[0015] Through the above technical solution, the tubular steel is placed on the upper part of the support seat for support. The support seat can be installed on the upper part of the base frame according to the specific size of the steel to be washed with phosphorus, so that the tubular steel is stably placed on the upper part of the base frame.
[0016] Furthermore, inclined surfaces are provided on both the left and right sides of the upper end of the chassis;
[0017] Through the above technical solution, the acidic solution, phosphate generated by the reaction and flushing water in the phosphorus washing process are gathered into the chute through the inclined surface, and then discharged and collected by the chute, which increases the convenience of liquid discharge after cleaning and prevents it from scattering to other locations.

Then, the movable frame is driven from front to back, and the remaining plurality of connecting pipes transport clean water to the nozzle position to flush the surface of the tubular steel after phosphorus washing. The acid solution, phosphate generated by the reaction and flushing water in the phosphorus washing process are gathered into the chute through the inclined surface and then discharged and collected by the chute. This not only improves the efficiency of phosphorus washing of the tubular steel, but also avoids the problem that phosphate is easy to accumulate and difficult to clean at the bottom of the phosphorus washing tank.
