[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] Combine Figures 1-4 A metal surface treatment pre-cleaning device includes a box body 1, a first conveyor belt 2 and a second conveyor belt 3. The first conveyor belt 2 and the second conveyor belt 3 are respectively installed at the rear end and the front end of the top of the box body 1. A cleaning component 4 is installed inside the box body 1, and a positioning component 5 is installed on the top of the box body 1.

[0025] See Figure 2 and Figure 3, it is further obtained that the cleaning assembly 4 includes two horizontal pipes 6 and two inclined plates 9, the two horizontal pipes 6 are fixedly installed inside the box body 1 and are located between the first conveyor belt 2 and the second conveyor belt 3, and a number of nozzles 7 are respectively installed at the bottom and top of the two horizontal pipes 6. Flow grooves 8 are opened on both sides of the interior of the box body 1, and the two inclined plates 9 are respectively installed below the first conveyor belt 2 and the second conveyor belt 3. Filters 10 are installed on the inner sides of the two inclined plates 9, and a sewage collecting box 11 is movably installed between the two inclined plates 9. An accommodating chamber 12 is provided near the bottom end of the interior of the box body 1, and a sealing cover 13 is connected to the drain outlet on one side of the accommodating chamber 12. A circulating pump 14 is installed on the back side of the accommodating chamber 12, and a water pipe 15 is connected between the water outlet of the circulating pump 14 and the two horizontal pipes 6.

[0026] The two transverse tubes 6 are symmetrical in vertical direction. The belt surfaces of the first conveyor belt 2 and the second conveyor belt 3 are in a network chain type. The two transverse tubes 6 are vertically disposed between the first conveyor belt 2 and the second conveyor belt 3 .

[0027] The two inclined plates 9 are symmetrically installed, and the dirt collecting box 11 is located between the two inclined plates 9 and is slidably arranged.

[0028] The height between the upper and lower ends of the circulation groove 8 is greater than the height between the upper and lower parts of the first conveyor belt 2 and the second conveyor belt 3 . The accommodating cavity 12 communicates with the two horizontal pipes 6 through the water pipe 15 .

[0029] Specifically, when the metal plate passes between the first conveyor belt 2 and the second conveyor belt 3, the water in the accommodating chamber 12 is transported to the two horizontal pipes 6 through the circulation pump 14, and is sprayed out through the nozzle 7 to simultaneously flush and clean the two surfaces of the metal plate. The cleaned sewage passes through the circulation groove 8 and is filtered through the filter screen 10 in the inclined plate 9, so that the large particles of debris and metal debris after flushing are collected in the sewage collection box 11, which is convenient for water filtration and recycling.

[0030] Example 2

[0031] See Figure 4 , and on the basis of Example 1, it is further obtained that the positioning assembly 5 includes a top plate 16 and two partitions 17, the top plate 16 is fixedly installed on the top of the box body 1, and the two partitions 17 are respectively fixedly installed at the front and rear ends of the bottom of the top plate 16, and an observation window 18 is provided inside the partition 17. A lifting frame 19 is movably installed through the top of the top plate 16, and a screw 20 is movably installed on the top of the top plate 16 and through the inside of the lifting frame 19. A turntable 21 is fixedly installed on the top of the screw 20, and a fixed frame 22 is fixedly installed at the bottom of the lifting frame 19. Guide rails 23 are installed on both sides of the fixed frame 22, and a pressure roller 24 is movably installed at the bottom of the fixed frame 22.

[0032] The bottom end of the screw rod 20 is connected to the top plate 16 via a bearing, and the lifting frame 19 is sleeved on the outside of the screw rod 20 in a threaded connection.

[0033] The lifting frame 19 passes through the top of the top plate 16 and is slidably arranged up and down. Both sides of the fixing frame 22 are guided and slidably arranged through guide rails 23.

[0034] Specifically, the pressure roller 24 is used to prevent the metal plate from detaching or deflecting during the flushing and cleaning process. The screw 20 drives the lifting frame 19 to slide up and down, and the fixed frame 22 drives the pressure roller 24 to move up and down to position metal plates of different thicknesses, making it easier to adjust the height of the pressure roller 24.

[0035] In actual operation, the first conveyor belt 2 and the second conveyor belt 3 are used to convey the metal plate. The metal plate is conveyed into the box body 1 by the first conveyor belt 2 and conveyed out by the second conveyor belt 3. When the metal plate passes between the first conveyor belt 2 and the second conveyor belt 3, water is sprayed onto the surface of the metal plate through the nozzle 7 to flush and clean the metal plate.

[0036] During the cleaning process, the water in the accommodating chamber 12 is transported to the two horizontal pipes 6 by the circulation pump 14 and sprayed out through the nozzle 7 to simultaneously flush and clean the two surfaces of the metal plate. The water at the top flows downward through the circulation groove 8 and the mesh chain belt surface of the first conveyor belt 2 and the second conveyor belt 3, and is prevented from overflowing by the inclined plate 9. The large particles of debris and metal debris in the flushed and cleaned water are filtered through the filter screen 10. The large particles of debris and metal debris automatically slide into the sewage collection box 11 through the inclined filter screen 10. The sewage collection box 11 is extracted for regular cleaning, and the filtered water flows into the accommodating chamber 12 for recycling.

[0037] When high-pressure washing is performed on the two sides of metal plates of different thicknesses, the observation window 18 is used to observe the internal cleaning status. By rotating the turntable 21, the screw 20 drives the lifting frame 19 to slide up and down, and drives the fixed frame 22 to slide up and down, so that the distance between the pressure roller 24 and the first conveyor belt 2 changes. When the metal plate passes through the bottom of the pressure roller 24 for washing, the pressure roller 24 prevents the metal plate from falling off, which can be suitable for positioning metal plates of different thicknesses.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
