[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1 、 Figure 2 As shown, the utility model provides a high-pressure spray brushing device for cold-rolled strip steel, including a flushing mechanism 1, the flushing mechanism 1 includes a flushing box 11, a tilted feed plate 12 is fixedly installed on the front side of the flushing box 11, a winding mechanism 14 is provided on the rear side of the flushing box 11, a U-shaped frame 13 is fixedly installed on the bottom of the flushing box 11, a water source collection box 2 is slidably connected in the grooves provided on the front and rear opposite surfaces of the U-shaped frame 13, a partition 23 is fixedly installed on the middle end of the inner wall of the water source collection box 2, and the partition 23 can divide the water source collection box 2 into a front side and a back side.

A flip sealing door 22 is movably installed on both sides of the left end of the water source collecting box 2, and a pull-out handle 21 is fixedly installed at the lower left side of the water source collecting box 2. The pull-out handle 21 can be used to pull the entire water source collecting box 2 out of the U-shaped frame 13 at the bottom of the flushing box body 11 to the left, so as to facilitate inspection and open the flip sealing door 22 for cleaning.

[0021] like Figure 3As shown, a water storage tank 111 is provided inside the flushing box 11, a water inlet 112 is fixedly connected to the top of the flushing box 11, and the water inlet 112 is connected to the water storage tank 111. The bottom of the flushing box 11 is fixedly connected to a hanging plate 113, and inclined spray heads 114 are fixedly installed on the upper and lower sides of the left end of the hanging plate 113. The two inclined spray heads 114 are inclined toward the middle end of the hanging plate 113, and the input ends of the two inclined spray heads 114 are connected to the bottom of the inner wall of the water storage tank 111. On the upper and lower sides of the right end of the wall, dewatering clamping wheels 115 are movably installed. The two dewatering clamping wheels 115 are both located on the rear side of the hanging plate 113. The winding mechanism 14 includes two brackets 141. A winding wheel 143 is movably connected between the opposite surfaces of the two brackets 141. A motor 142 is fixedly installed on the left side of the left bracket 141. The output shaft of the motor 142 is fixedly connected to the left side of the winding wheel 143. The winding wheel 143 is driven to rotate by the motor 142 on the bracket 141 to reel the cold-rolled strip.

[0022] The cold-rolled strip enters the inner cavity of the washing box 11 through the inclined inlet plate 12, and is pressed by the pressure roller 24 to make the cold-rolled strip contact with the water source in the inner cavity of the front side of the water source collection box 2 for preliminary soaking to remove large particles of impurities on the surface. The direction is then changed by the changing roller 231 on the top of the partition 23, and the strip is sprayed with high pressure by the inclined spray heads 114 on the upper and lower sides of the left end of the hanging plate 113. After that, the strip passes between the two dewatering clamping wheels 115 to remove excess water, and then is reeled by the reeling wheel 143.

[0023] like Figure 4 As shown, a filter plate 1 25 is fixedly installed on the front side of the inner cavity of the water source collection box 2 and is located on the front side of the partition 23. A filter plate 26 is fixedly installed on the rear side of the inner cavity of the water source collection box 2 and is located on the rear side of the partition 23. Water pumps 232 are fixedly installed on the bottom of the left and right sides of the partition 23. The input end of the front water pump 232 is located below the filter plate 1 25, the output end of the left water pump 232 is located below the filter plate 26, the input end of the rear water pump 232 is located below the filter plate 26, and the output end of the rear water pump 232 is located below the filter plate 1 25.

[0024] The height of the water source at the front side of the inner cavity of the water source collection box 2 is controlled to be slightly above the pressure roller 24. The large particles of impurities dropped by the cold-rolled strip in the inner cavity at the front side of the water source collection box 2 will fall on the filter plate 1 25, and the impurities and water source flushed by the inclined spray head 114 will fall into the inner cavity at the rear side of the water source collection box 2 and fall above the filter plate 2 26. By starting the water pump 232 at the bottom of the front side of the partition 23, the water source in the inner cavity at the front side of the water source collection box 2 can be discharged into the inner cavity at the rear side of the water source collection box 2. By opening the flip sealing door 22 at the front left end of the water source collection box 2, the impurities on the surface of the filter plate 1 25 can be cleaned. By starting the water pump 232 at the bottom of the rear side of the partition 23, the water source in the inner cavity at the rear side of the water source collection box 2 can be discharged into the inner cavity at the front side of the water source collection box 2, so that the inner cavities at the front and rear sides of the water source collection box 2 can be emptied of water, and the impurities will be blocked by the filter plate 1 25 and the filter plate 2 26 and remain on the surface, making it convenient to clean.

[0025] like Figure 5 As shown, the dewatering clamping wheel 115 includes a rotating roller 1151, and a Velcro hook surface 1153 is fixedly installed on the outer wall of the rotating roller 1151. The outer wall of the Velcro hook surface 1153 is bonded and connected with a Velcro fur surface 1154. The outer wall of the Velcro fur surface 1154 is fixedly connected with an absorbent cloth 1152. The front and rear lengths of the absorbent cloth 1152 are consistent with the side circle diameter of the rotating roller 1151. Therefore, the absorbent cloth 1152 can be completely attached to the surface of the rotating roller 1151 using the Velcro fur surface 1154 and the Velcro hook surface 1153. When cleaning is needed, it can be directly torn off, which makes it convenient to clean the absorbent cloth 1152.

[0026] The following is a detailed description of the working principle of the high-pressure spray brushing device for cold-rolled strip steel.

[0027] like Figure 1-5As shown, the motor 142 on the bracket 141 drives the winding wheel 143 to rotate to reel the cold-rolled strip. During reeling, the cold-rolled strip enters the inner cavity of the washing box 11 through the inclined feed plate 12, and the pressure of the pressure roller 24 is used to make the cold-rolled strip contact with the water source in the inner cavity on the front side of the water source collection box 2 for preliminary soaking to remove large particles of impurities on the surface. Then, the direction change is completed by the changing roller 231 on the top of the partition 23, and the strip is sprayed with high pressure through the inclined spray heads 114 on the upper and lower sides of the left end of the hanging plate 113. Then, the strip passes between the two dewatering clamping wheels 115 so that the moisture on the upper and lower surfaces of the cold-rolled strip is absorbed by the absorbent cloth 1152. Finally, the reeling is completed and the cold-rolled strip falls into the inner cavity on the front side of the water source collection box 2. The large particles of impurities will fall on the filter plate 1 25, and the impurities and water source flushed by the inclined sprinkler head 114 will fall into the rear inner cavity of the water source collection box 2 and fall on the top of the filter plate 2 26. By starting the water pump 232 at the bottom front side of the partition 23, the water source in the front inner cavity of the water source collection box 2 can be discharged into the rear inner cavity of the water source collection box 2. The flip sealing door 22 at the front left end of the water source collection box 2 can be opened to clean the impurities on the surface of the filter plate 1 25. By starting the water pump 232 at the bottom rear side of the partition 23, the water source in the rear inner cavity of the water source collection box 2 can be discharged into the front inner cavity of the water source collection box 2. The flip sealing door 22 at the rear left end of the water source collection box 2 can be opened to clean the impurities on the surface of the filter plate 2 26.

[0028] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are intended to be within the scope of protection of the present invention.
