Description

Technical Field

[0001] The utility model relates to the technical field of metal surface treatment equipment, in particular to an ultrasonic scale removal device for stainless steel strips. Background Art

[0002] Oxide scale is a corrosion product formed when steel undergoes oxidation at high temperatures. It is composed of ferrous oxide, ferroferric oxide, and ferric oxide. Oxide scale is brittle and inelastic, and easily cracks and breaks off under mechanical and thermal processing.

[0003] The production of oxide scale not only causes a large amount of steel loss, but also leads to many adverse consequences, mainly including: 1. Oxide scale makes the surface of forgings rough. If the oxide scale is pressed into the forgings during forging, it will seriously become scrap; 2. Removal of oxide scale requires some additional auxiliary processes and equipment; 3. Oxide scale has a high hardness, which not only increases the consumption of deformation energy during forging, but also accelerates the wear of the forging die and reduces its service life.

[0004] To improve the machining quality of workpieces, it is necessary to remove the oxide scale on the surface. Currently, the following methods are mainly used to remove the oxide scale on stainless steel at home and abroad: 1. Physical and mechanical methods, which mainly use dynamic forces to cause friction between the medium and the stainless steel surface. This method has a simple process but low processing efficiency. 2. Chemical methods, which mainly use pickling to produce a chemical reaction with the stainless steel surface. This method is time-consuming and produces a large amount of nitrogen oxides, which is very harmful to the environment.

[0005] In recent years, attention has shifted to electrolysis as a descaling method. Following electrolysis, ultrasonic waves are combined with environmentally friendly metal descaling cleaning fluids to achieve high treatment efficiency while minimizing environmental pollution. Ultrasonic rust removal relies on wave vibrations to remove impurities from the metal surface of the workpiece being derusted and descaled. However, the accumulation of impurities in the treatment tank can affect the cleaning fluid's efficiency in descaling and rust removal. Utility Model Content

[0024] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0025] Please refer to Figures 1 to 3 , an ultrasonic descaling device for stainless steel strips, comprising a treatment tank 1, an ultrasonic cleaner 2 and a filter assembly;

[0026] The treatment tank 1 is provided with a metal rust removal cleaning liquid, and the side wall of the treatment tank 1 is provided with an ultrasonic generator;

[0027] The filtering assembly includes a circulation pipe 3, a circulation pump 4 and a filtering tank 5;

[0028] The circulation pipe 3 includes an outflow pipe and a return pipe; a circulation pump 4 is provided on the outflow pipe, one end of the outflow pipe is connected to the bottom surface of the treatment tank 1, and the water outlet end of the outflow pipe is connected to the filter tank 5; one end of the return pipe is connected to the bottom surface of the filter tank 5, and the other end is connected to the treatment tank 1;

[0029] The filter pool 5 includes a filter rod and an outlet pipe 51; the water inlet end of the outlet pipe 51 protrudes from the bottom surface of the filter pool 5, and the water outlet end of the outlet pipe 51 passes through the bottom wall of the filter pool 5 and is connected to the return pipe; the filter rod includes a hollow frustum-shaped filter cartridge 52, and the side wall of the filter cartridge 52 is provided with water flow holes; the side surface of the filter cartridge 52 is covered with non-woven fabric 53; the lower end of the filter cartridge 52 is provided with an opening and is sleeved on the outside of the water inlet end of the outlet pipe 51.

[0030] The beneficial effects of the present invention are as follows: the ultrasonic scale removal device for stainless steel bars of the present invention is used to quickly remove rust and scale from stainless steel bars under the combined action of chemical etching with a rust removal solution and ultrasonic vibration. The present invention forms a filter rod by wrapping a non-woven fabric 53 around a filter cartridge 52 to filter solid impurities in the cleaning liquid. The filter rod has a simple structure, low cost, and is easy to replace after a filtration cycle. The filter assembly of the present invention is designed for the use scenario of the present application, and while meeting the filtration requirements of the present application, it is low cost and highly cost-effective.

[0031] Furthermore, in the above-mentioned ultrasonic scale removal device for stainless steel strips, three water outlet pipes 51 are provided, and a filter rod is sleeved on each water outlet pipe 51 .

[0032] As can be seen from the above description, the provision of three water outlet pipes 51 and three filter rods improves the filtering efficiency.

[0033] Furthermore, in the above-mentioned ultrasonic scale removal device for stainless steel strips, the pore size of the non-woven fabric 53 is 200-300 meshes.

[0034] As can be seen from the above description, setting the size of the above-mentioned aperture can improve the filtration efficiency while filtering impurities to the maximum extent.

[0035] Furthermore, in the above-mentioned ultrasonic scale removal device for stainless steel strips, the bottom surface of the filter tank 5 is higher than the height of the treatment tank 1 .

[0036] As can be seen from the above description, the above arrangement creates a height difference between the filter tank 5 and the treatment super, utilizing gravity to promote filtration.

[0037] Furthermore, in the above-mentioned ultrasonic scale removal device for stainless steel strips, an overflow groove 11 is provided at the edge of the treatment tank 1, and the overflow groove 11 is connected to the outflow pipe through a pipe.

[0038] As can be seen from the above description, the metal rust removal cleaning liquid is prone to foaming and overflowing under the action of ultrasonic waves. The overflow tank 11 is provided so that the liquid can be recycled and the environment can be kept clean.

[0039] Furthermore, in the above-mentioned ultrasonic scale removal device for stainless steel strips, the radial cross-section of the treatment tank 1 is U-shaped.

[0040] From the above description, it can be seen that the radial cross-section of the treatment tank 1 is U-shaped, which is convenient for the outflow pipe to absorb the bottom metal rust removal cleaning liquid with many impurities. The stainless steel bar is also similar to a cylinder. The U-shaped treatment tank 1 saves the amount of metal rust removal cleaning liquid on the basis of accommodating the stainless steel bar.

[0041] Example 1:

[0042] like Figures 1 to 3 As shown, an ultrasonic scale removal device for stainless steel strips of this embodiment includes a treatment tank 1, an ultrasonic cleaner 2 and a filter assembly;

[0043] The treatment tank 1 is provided with a metal rust removal cleaning liquid, and the side wall of the treatment tank 1 is provided with an ultrasonic generator;

[0044] The filtering assembly includes a circulation pipe 3, a circulation pump 4 and a filtering tank 5;

[0045] The circulation pipe 3 includes an outflow pipe and a return pipe; a circulation pump 4 is provided on the outflow pipe, one end of the outflow pipe is connected to the bottom surface of the treatment tank 1, and the water outlet end of the outflow pipe is connected to the filter tank 5; one end of the return pipe is connected to the bottom surface of the filter tank 5, and the other end is connected to the treatment tank 1;

[0046] The filter tank 5 includes a filter rod and an outlet pipe 51. The inlet end of the outlet pipe 51 protrudes from the bottom surface of the filter tank 5, and the outlet end of the outlet pipe 51 passes through the bottom wall of the filter tank 5 and connects to the return pipe. The filter rod includes a hollow, frustoconical filter cartridge 52 with water flow holes on its sidewall. The side of the filter cartridge 52 is covered with a non-woven fabric 53. The lower end of the filter cartridge 52 has an opening and is inserted into the outer side of the inlet end of the outlet pipe 51. There are three outlet pipes 51, each of which is inserted into a filter rod. The pore size of the non-woven fabric 53 is 200-300 mesh.

[0047] The edge of the treatment tank 1 is provided with an overflow groove 11, and the overflow groove 11 is connected to the outflow pipe through a pipe. The radial cross section of the treatment tank 1 is U-shaped.

[0048] Environmentally friendly metal rust removal liquid is placed in the treatment tank;

[0049] The rolled stainless steel bars are placed in the treatment tank, where they are quickly rusted by the combined action of chemical etching with rust removal liquid and ultrasonic vibration.

[0050] Turn on the circulation pump, and the environmentally friendly metal rust removal liquid in the treatment tank flows into the filter tank, is filtered by the non-woven fabric on the filter cartridge, and then flows back to the treatment tank; the solid impurities in the cleaning liquid in the treatment tank are filtered out;

[0051] After a period of filtration, the filtration efficiency of the filter rod decreases. Pick up the filter rod and use another unused filter rod to directly insert it into the water outlet pipe (the frustum-shaped filter cartridge is convenient for interference fit). The filter rod can be replaced. The replacement of the filter rod is simple and fast.
