DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1The utility model provides a technical solution for pickling equipment of strip steel: a pickling equipment of strip steel comprises a pickling machine 1, wherein an acid tank 2, a pickling tank 21 and a filter chamber 14 are sequentially arranged at the bottom of the pickling machine 1 from left to right, a pair of first electric rollers 4 are installed at the outer top of the acid tank 2 and in the pickling machine 1, a first steering roller 5, a second steering roller 8, a third steering roller 9, a fourth steering roller 10 and a fifth steering roller 18 are sequentially arranged above the pickling tank 21 from left to right, a pair of cleaning rollers 19 and a pair of second electric rollers 20 are arranged in the pickling machine 1 above the filter chamber 14, and a plurality of rollers are arranged at the bottom of the acid tank 2 and the filter chamber 14. A dry extraction port 3, a filter plate 22 is arranged above the wall between the acid tank 2 and the pickling tank 21, a pair of acid injection ports 6 are arranged below the first turning roller 5, a spray port 7 is installed at the inner bottom of the wall between the acid tank 2 and the pickling tank 21, a pair of air injection ports 17 are arranged below the fifth turning roller 18, an acid pump 12 is installed at the inner bottom of the wall between the pickling tank 21 and the filter chamber 14, the acid pump 12 is connected to a suction pipe 11 into the pickling tank 21, the acid pump 12 is connected to a liquid outlet pipe 13 to the top of the filter chamber 14, a filter box 15 is installed in the filter chamber 14, and a filter chamber sealing door 16 is installed on the top outer wall of the filter chamber 14.

[0016] Furthermore, the pair of first electric rollers 4, the pair of cleaning rollers 19 and the pair of second electric rollers 20 are all connected to drive motors.

[0017] Furthermore, a plurality of filter holes are installed on the filter plate 22 and the filter box 15 .

[0018] Furthermore, the extraction port 3 is connected to an external circulation pump, and the liquid outlet of the circulation pump is connected to the acid injection port 6 and the spray port 7 .

[0019] Furthermore, the pair of air injection ports 17 are connected to an air pump.

[0020] Embodiment: When the device is in use, the strip passes through the first motor roller 4, the first steering roller 5, the second steering roller 8, the third steering roller 9, the fourth steering roller 10, the fifth steering roller 18, the cleaning roller 19 and the second motor roller 20 in the manner as shown in the figure.

[0021] During the pickling process, the strip first passes through a pair of first electric rollers 4 and the first steering roller 5, and then enters the pickling tank 21 for pickling under the guidance of the first steering roller 5, and then passes through the second steering roller 8, the third steering roller 9, the fourth steering roller 10 and the fifth steering roller 18 for repeated pickling, and then enters the cleaning roller 19 and the second electric roller 20 to finally complete the discharge.

[0022] After the impurities generated during the pickling process are precipitated into the pickling tank 21, they are sprayed to the position in the direction of the suction pipe 11 under the action of the spray port 7. The acid pump 12 extracts the acid containing impurities through the suction pipe 11 and pumps it to the top of the filter box 15. The acid is filtered by the filter box 15 and enters the filter chamber 14. At the same time, the acid containing impurities is filtered by the filter plate 22 and then flows into the acid tank 2. At this time, both the acid tank 2 and the filter chamber 14 are filled with clean acid.

[0023] The clean acid in the acid tank 2 and the filter chamber 14 is pumped to the first turning roller 5 and the spray port 7 through an external circulation pump, and the acid at the acid spray port 6 is sprayed on the strip for further pickling. The acid at the spray port 7 is passed into the pickling tank 21, which can not only push the acid containing impurities to the suction pipe 11, but also form an acid circulation in the pickling tank 21, continuously purify the acid, and improve the pickling effect.

[0024] The air pump is connected to the air jet 17, and the nozzle of the air jet 17 is aimed at the strip steel, so that when the strip steel passes through the air jet 17, the high-pressure air blows away the acid liquid on the strip steel, thereby reducing the residual acid liquid.

[0025] After the strip passes through the cleaning roller 19, the rotating cleaning roller 19 can wipe the acid liquid remaining on the surface of the strip to keep the strip clean.

[0026] When cleaning, the filter chamber sealing door 16 can be opened and the filter box 15 can be taken out therefrom for cleaning.

[0027] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, but do not necessarily require or imply any such actual relationship or order between these entities or operations.
