Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically a water washing device for steel belts. Background Technology

[0002] Steel strip, usually supplied in coils, has advantages such as high dimensional accuracy, good surface quality, easy processing, and material saving. However, the steel strip used must be cleaned before subsequent processing or galvanizing. To meet these requirements, the surface of the steel strip is usually ultrasonically or activated for cleaning. After ultrasonic or activated cleaning, residual cleaning solution will remain on the steel strip. Therefore, it is necessary to design a water washing device that can be directly connected online to clean it and keep the steel strip clean for subsequent processing. Utility Model Content

[0003] The purpose of this invention is to provide a water washing device for steel strips to solve the technical problems in the background art.

[0004] To achieve the aforementioned objectives, this utility model provides the following technical solution:

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Specific Implementation Example 1: Please refer to Figures 1 to 10 In this embodiment of the present invention, a water washing device for steel strip includes a hollow water washing tank 11. From left to right, the water washing tank 11 contains a first guiding mechanism 12, a water washing chamber 13, and a first drying assembly 9. The water washing tank 11 has a third through hole 1101 and a fourth through hole 1102 on its left and right sides, respectively, for feeding and discharging materials. The first guiding mechanism 12 includes a first mounting frame 1201, a first support wheel 1202, and a second support wheel 1203. The first mounting frame 1201 is fixedly installed on the water washing tank 11. The first support wheel 1202 and the second support wheel 1203 are spaced vertically and rotatably mounted on the front side of the first mounting frame 1201. The steel strip 1 passes between the first support wheel 1202 and the second support wheel 1203 into the water washing tank 11. Supported by the first support wheel 1202 and the second support wheel 1203, the steel strip 1 can be transported more smoothly and in a more directional manner.

[0024] In this application, the first mounting bracket 1201 includes a first connecting plate 1201-1 and a second connecting plate 1201-2. The second connecting plate 1201-2 has an L-shaped structure. One end of the first connecting plate 1201-1 is vertically fixed to the side wall of the washing tank 11, and the other end is suspended inside the washing tank 11. The second connecting plate 1201-2 includes a horizontal plate 1201-2A and a vertical plate 1201-2B. The horizontal plate 1201-2A is fixed to the first connecting plate 1201-1, and the vertical plate 1201-2B is vertically fixed to one side of the horizontal plate 1201-2A. A limiting hole 1201-2C is formed on the vertical plate 1201-2B along the vertical direction. 201-2C has an elongated through-hole structure. The first support wheel 1202 and the second support wheel 1203 are installed in the limiting hole 1201-2C. The first support wheel 1202 is installed in the limiting hole 1201-2C via a support shaft 1205. The front end of the support shaft 1205 is rotatably mounted with the first support wheel 1202, and the other side passes through the limiting hole 1201-2C. The support shaft 1205 is then locked in the limiting hole 1201-2C by a nut 1204. Because the limiting hole 1201-2C has an elongated hole structure, the distance between the first support wheel 1202 and the second support wheel 1203 can be adjusted according to the different widths of the steel strip 1, thus enhancing its versatility. In addition, the washing tank 11 below the second support wheel 1203 is provided with several rectangular arrays of second drain holes. The second drain holes can be connected to a circulating water pump or other means through water pipes to recycle the water in the washing tank.

[0025] The washing chamber 13 includes a hollow washing sub-box 1301. The bottom of the washing sub-box 1301 is spaced apart from the bottom of the washing chamber 13. A first water outlet 1301-1 and a second water outlet 1301-2 are symmetrically arranged on the left and right sides of the washing sub-box 1301. The first water outlet 1301-1 and the second water outlet 1301-2 have the same structure and are both equipped with a limiting component 1302. The limiting component 1302 is used to limit the width of the first water outlet 1301-1 and the second water outlet 1301-2. 1302 includes a first insert 1302-1 and a second insert 1302-2. The first insert 1302-1 and the second insert 1302-2 have the same structure and are symmetrically inserted and removed at the first outlet 1301-1 or the second outlet 1301-2. The first insert 1302-1 has a first insertion hole 1302-1A, which is an open structure and has both its upper and lower ends penetrating through the upper and lower end faces of the first insert 1302-1. The first insert 1302-1 is inserted and snapped into the first outlet 1301-1. On the side wall, there are several first water inlet holes 1301-3 on the front and rear sides of the bottom of the washing tank 1301. The first water inlet holes 1301-3 are arranged in a rectangular row near the center of the washing tank 1301. The center of the washing tank 11 has a water inlet hole 1104 for connecting to a water pump for water supply. High-pressure water flows in through the water inlet hole 1104. After the high-pressure water hits the bottom of the washing tank 1301, it is agitated by the bottom of the washing tank 1301 and flows through the first water inlet holes 1301-3. 3. The water is poured into the washing tank 1301 to rinse the steel belt 1. The width of the first outlet 1301-1 and the second outlet 1301-2 can be adjusted to control the speed of water outflow from the washing tank 1301. An overflow pipe 16 is also installed above the washing tank 1301 to supply water to the washing tank 1301, ensuring that the cleaning water can soak the steel belt 1 for cleaning. A first detection probe 15 is also installed above the washing chamber 13 to detect the pH value of the water source in the washing tank 1301.

[0026] In this application, the first drying assembly 9 includes a first support base 901, a first air knife 902, and a second air knife 903. A first air duct 904 is installed below the first support base 901 for connecting an air supply device to provide air to the first air knife 902 and the second air knife 903. The first air knife 902 and the second air knife 903 are fixed above the first support base 901 and are both installed perpendicular to the first support base 901. The first air knife 902 and the second air knife 903 have the same structure and are symmetrically arranged front and back on the first support base 901. The first air knife 902 is installed obliquely on the first support base 901, and the included angle α between the first air knife 902 and the second air knife 903 is 90-120 degrees. In this embodiment, the included angle α between the first air knife 902 and the second air knife 903 is 60 degrees. 02 includes a first air knife body 902-1 with a hollow cavity structure. The first air knife body 902-1 has a rectangular structure. The end face of the first air knife body 902-1 near the body of the second air knife 903 has a conical air outlet 902-2. The tip of the air outlet 902-2 is the air outlet 902-3. The air outlet 902-3 is set in a vertical direction and has a flat structure. The first air knife 902 and the second air knife 903 are both inclined to blow dry the steel belt 1 passing between the first air knife 902 and the second air knife 903. The airflow "cuts obliquely" along the surface of the steel belt 1, generating a transverse shearing force, which is more conducive to blowing the liquid away from the surface of the steel belt 1. At the same time, since the steel belt 1 is transported in a vertical direction, it further prevents the liquid from remaining on both sides of the steel belt 1.

[0027] Compared with the prior art, the steel strip washing device of this application is easy to operate. It uses the first water inlet hole of the matrix arrangement in the washing chamber to wash the steel strip. After the high-pressure water hits the bottom of the washing sub-box, it is splashed by the bottom of the washing sub-box and flows into the washing sub-box through the first water inlet hole to rinse the steel strip. It causes little damage to the steel strip and can ensure the quality of the cleaning. In addition, this application also has a drying component to dry the cleaned steel strip online, reduce the residue of cleaning liquid and improve the cleaning quality of the steel strip. Since the steel strip is transported in a vertical direction, it further prevents liquid residue from remaining on both sides of the steel strip.
