The outer surface of the U-shaped tube 5 is connected to a plurality of nozzles 6. Two layers of filter screens 7 are provided at the bottom between the four inner walls of the cleaning box 1, and disassembly mechanisms 8 for facilitating the disassembly of the filter screen 7 are provided at the upper and lower ends of the front of the left and right side walls of the cleaning box 1.

[0023] Among them, the water inlet end of the water pump 4 is connected to a water inlet pipe, the other end of the water inlet pipe passes through the top of the left side wall of the inner cavity of the liquid storage tank 3 and extends to the inner cavity of the liquid storage tank 3, and water holes are provided on the lower surface of the cleaning tank 1 and the upper surface of the liquid storage tank 3. The number of water holes is not less than two and is evenly distributed on the lower surface of the cleaning tank 1 and the upper surface of the liquid storage tank 3.

[0024] It should be noted that the aperture of the lower filter screen 7 is smaller than that of the upper filter screen 7, which can perform secondary filtration on the cleaning liquid, thereby improving the filtering effect of the filter screen 7. The back of the liquid storage tank 3 is connected to a switch valve for draining the cleaning liquid.

[0025] See also Figure 2-3 , in order to make the cleaning liquid spray evenly on the surface of the scrap metal, the placing mechanism 2 in this embodiment includes four rotating plates 201 rotatably connected to the left and right ends of the inner cavity of the cleaning box 1 through bearings, and a connecting rod 202 is fixed between the opposite sides of the front and rear rotating plates 201. The front and rear rotating plates 201 and the plurality of connecting rods 202 form a cylinder, and the inner cavity of the cylinder is provided with a receiving box 203. The front and rear ends of the left and right sides of the receiving box 203 are provided with sliding sleeves 204, and the sliding sleeve 204 is slidably connected to one of the connecting rods 202. The left and right ends of the upper surface of the receiving box 203 are provided with threaded grooves 205, and the upper surface of the receiving box 203 is provided with a movable plate 206. The sealed door hinged on one side of 201, and then the accommodating box 203 is pulled out. The movement of the accommodating box 203 drives the sliding sleeve 204 to move on the outer surface of the connecting rod 202, and then the position of the movable plate 206 can be adjusted according to the size of the scrap metal. The left and right ends of the upper surface of the movable plate 206 are threadedly connected to a threaded rod 207 with one end passing through and extending to its lower surface. A mesh partition 208 is fixed to the lower surface of the movable plate 206. Put the scrap metal into the side opposite to the accommodating slot and the mesh partition 208, then move the movable plate 206 to make the mesh partition 208 fit with one side of the scrap metal, and then screw the threaded rod 207 on the upper surface of the movable plate 206 into the threaded groove 205 just below it.

[0026] It can be understood that after the scrap metal is placed in, the sealed door hinged on one side of the rotating plate 201 is closed, the drive motor and the water pump 4 are started, and the output shaft of the drive motor drives the rotating plate 201 to rotate, and then drives the receiving box 203 to rotate through the connecting rod 202. At this time, the water pump 4 draws the cleaning liquid into the U-shaped tube 5 and sprays it through the nozzle 6 for spray cleaning. The water and impurities after spraying will be filtered through the two layers of filter screens 7, and finally flow back to the inner cavity of the liquid storage tank 3 through the water hole.

[0028] It should be noted that one side of the storage box 203 is hingedly connected to a sealed door through a hinged seat. The storage box 203 has a mesh structure, which facilitates the falling of impurities on the surface of scrap metal. The inner cavity of the left and right side walls of the storage box 203 are fixed with limit bars, and the left and right sides of the mesh partition 208 are fixed with limit rods. The limit rods make horizontal linear motion in the inner cavity of the limit bar, which can limit the movement of the mesh partition 208.

[0029] See also Figure 4 In order to improve the filtering effect of the filter 7, the disassembly mechanism 8 in this embodiment includes mounting grooves 801 provided on the upper and lower ends of the front sides of the left and right side walls of the cleaning box 1, and telescopic rods 802 are fixed on the upper and lower ends of the opposite sides of the left and right mounting grooves 801. The outer surface of the telescopic rod 802 is movably covered with a spring 803, and a plug-in plate 804 is fixed on the opposite side of the left and right telescopic rods 802. The plug-in plate 804 is moved toward the side close to the telescopic rod 802. The movement of the plug-in plate 804 can squeeze the telescopic rod 802 and the spring 803. Slots 805 are provided on the left and right sides of the filter 7, so that the protrusion of the plug-in plate 804 moves into the inner cavity of the mounting groove 801, which can release the limit of the filter 7, and then the filter 7 can be pulled out and cleaned.

[0030] The two ends of the spring 803 are respectively fixedly connected to the mounting slot 801 and the side opposite to the plug-in board 804 , and the outer diameter of the protruding portion of the plug-in board 804 is adapted to the inner diameter of the slot 805 .

[0031] The working principle of the above embodiment is:

[0032] (1) When cleaning the surface of scrap metal, first open the door of the cleaning box 1, then open the sealed door hinged on one side of the rotating plate 201, and then pull out the receiving box 203. The movement of the receiving box 203 drives the sliding sleeve 204 to move on the outer surface of the connecting rod 202. Then, the position of the movable plate 206 can be adjusted according to the size of the scrap metal. First, rotate the threaded rods 207 at both ends so that they move upward in the inner cavity of the threaded groove 205. The limit of the two ends of the movable plate 206 can be released, and then the scrap metal is placed in the receiving groove opposite to the mesh partition 208. One side, then move the movable plate 206 to make the mesh partition 208 fit with one side of the scrap metal, and then screw the threaded rod 207 on the upper surface of the movable plate 206 into the threaded groove 205 on its lower side, and then put the scrap metal in one by one, then close the sealing door hinged on one side of the rotating plate 201, start the driving motor and water pump 4, the output shaft of the driving motor drives the rotating plate 201 to rotate, and then drives the containing box 203 to rotate through the connecting rod 202, at this time the water pump 4 pumps the cleaning liquid into the U-shaped tube 5, and sprays it through the nozzle 6, which can be sprayed and cleaned.

[0033] (2) The water and impurities after spraying will be filtered through the two layers of filter screens 7 and finally flow back to the inner cavity of the liquid storage tank 3 through the water holes. In order to clean the surface of the filter screen 7, first move the plug-in board 804 to the side close to the telescopic rod 802. The movement of the plug-in board 804 can squeeze the telescopic rod 802 and the spring 803, so that the protrusion of the plug-in board 804 moves into the inner cavity of the installation groove 801, which can release the limit of the filter screen 7 and then pull out the filter screen 7 for cleaning.
