Description

Technical Field

[0001] The utility model relates to the technical field of degreasing devices, in particular to a degreasing device for a steel strip production line. Background Art

[0002] Steel strip degreasing refers to the process of removing oil, impurities, etc. on the surface of the steel strip by chemical, physical or mechanical methods to improve its surface cleanliness and handling performance. The purpose of degreasing is to ensure that the surface of the steel strip can meet the required requirements during subsequent processing or coating. Common degreasing methods include solvent degreasing, alkaline degreasing, acid degreasing, etc.

[0003] During the use of the existing steel strip degreasing device, a large amount of iron filings, i.e. impurities, are attached to the surface of the steel strip. These iron filings and impurities float on the surface of the pickling liquid during the pickling and degreasing process, and are easily attached to the surface of the steel strip again when the steel strip leaves the pickling liquid after pickling and degreasing, resulting in more impurities on the surface of the steel strip and reducing the degreasing quality.

DETAILED DESCRIPTION

[0023] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0024] like Figure 1-Figure 4 As shown, the degreasing device of the steel strip production line provided in this embodiment includes a degreasing box 1, a cleaning component 2 is installed in the upper middle part of the degreasing box 1, and a collecting component 3 is arranged in the upper middle part of the cleaning component 2;

[0025] The cleaning assembly 2 includes three groups of transmission shafts 201 rotatably connected to the degreasing box 1. The three groups of transmission shafts 201 are distributed in a triangular structure. A plurality of tooth grooves 202 are evenly provided on a wall of the transmission shaft 201. The transmission shaft 201 drives the magnetic block 204 and the conveyor belt 203 to rotate through the tooth grooves 202. The conveyor belt 203 is nested on the outer side of the transmission shaft 201. The conveyor belt 203 can adhere to impurities in the pickling solution. A plurality of magnetic blocks 204 are evenly installed on one end of the conveyor belt 203 facing the transmission shaft 201. The magnetic blocks 204 can effectively absorb iron filings in the pickling solution.

[0026] The collecting component 3 includes a collecting box 301 located above the top of the conveyor belt 203, through which impurities and iron filings are discharged, and an elastic retractable plate 302 is fixed to one side of the bottom of the collecting box 301. The elastic retractable plate 302 can be in close contact with the conveyor belt 203 due to its own elasticity, so as to scrape off and separate impurities and iron filings adhered to its surface, and the movable end of the elastic retractable plate 302 is against the top of the conveyor belt 203, and a plurality of groups of heating tubes 303 are equidistantly installed on one side of the elastic retractable plate 302, which can heat and evaporate the moisture carried by the impurities and iron filings themselves.

[0027] like Figure 1-Figure 2 As shown, the collecting box 301 is a funnel-shaped structure, and a connecting pipe 4 for connecting an external extraction device is installed on the top of the collecting box 301, so that the extraction device can be connected to the collecting box 301 through the connecting pipe 4 to extract impurities and iron filings through the collecting box 301.

[0028] like Figure 1-Figure 2 As shown, the tooth groove 202 matches the size of the magnet 204 , and the transmission shaft 201 is driven by an external electric device, so that the magnet 204 can rotate synchronously through the tooth groove 202 during the rotation of the conveyor belt 203 .

[0029] like Figure 1-Figure 2 As shown, two groups of outer guide frames 5 are symmetrically installed on both sides of the degreasing box 1. The two groups of outer guide frames 5 are at the same horizontal height, and through grooves 9 are opened on the degreasing box 1 corresponding to the outer guide frames 5, so as to facilitate the steel strip to be introduced into and out of the degreasing box 1 through the two groups of outer guide frames 5.

[0030] like Figure 1-Figure 2As shown, the outer guide frame 5 includes fixed seats 501 symmetrically mounted on the degreasing box 1, and two groups of guide rollers 502 are rotatably connected between the fixed seats 501, so that the steel belt can be moved through the guide rollers 502 during the steel belt guiding process.

[0031] like Figure 1-Figure 2 As shown, multiple groups of guide rollers 6 are installed in the degreasing box 1, and each group of guide rollers 6 has two guide rollers. The multiple groups of guide rollers 6 are trapezoidal in structure. The guide rollers 6 guide the steel strip during its movement, so that the steel strip enters the pickling liquid for degreasing treatment.

[0032] like Figure 1-Figure 2 As shown, a feed pipe 7 is connected to the upper side of the degreasing box 1, and a discharge pipe 8 is connected to the lower side of the degreasing box 1, so that the pickling liquid can enter the degreasing box 1 through the feed pipe 7 and the used pickling liquid can be discharged from the degreasing box 1 through the discharge pipe 8.

[0033] Working principle of the device: When the device is used, the steel strip is moved by the external unwinding and winding equipment, and the steel strip enters the degreasing box 1 from the through slot 9 through the outer guide frame 5 on one side, and the pickling liquid is transported to the degreasing box 1 through the feed pipe 7. The steel strip moves on the guide roller 6 in the degreasing box 1, and the guide roller 6 makes the steel strip immersed in the pickling liquid for pickling and degreasing. After the degreasing is completed, the steel strip is discharged from the degreasing box 1 through the through slot 9 and the outer guide frame 5 on the other side for subsequent treatment;

[0034] During the pickling and degreasing process, the conveying shaft drives the magnetic block 204 and the conveyor belt 203 to rotate through the tooth groove 202. During the rotation of the conveyor belt 203, impurities are adhered, and the iron filings are adsorbed by the magnetic block 204 and moved to the top of the pickling liquid. Then the elastic telescopic plate 302 can scrape the impurities and iron filings on the conveyor belt 203, and heat and evaporate the moisture contained in them through the heating tube 303. The external extraction equipment is connected to the collection box 301 through the connecting tube 4, and then the impurities and iron filings are extracted and collected uniformly to prevent these impurities and iron filings from adhering to the surface of the steel belt again, thereby improving the degreasing quality.

[0035] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
