[0032] The adjusting groove is opened along the traveling direction of the steel casing 6, and vertical sliding grooves for the two ends of the storage box 13 to slide in are respectively opened at both ends of the adjusting groove.

[0033] Specifically, the adjustment mechanism includes four bases fixedly installed at the bottom of the adjustment grooves on both sides of the storage box 13, top plates fixedly installed at the tops of the adjustment grooves on both sides of the storage box 13, screws 15 respectively installed between the bases and the top plates and rotatable, and an adjustment plate 14 fixedly installed at the bottom of the storage box 13.

The deposition structure includes a top inclined plate fixedly installed at the bottom of the filter barrel and inclined toward the flow guide box, and a bottom inclined plate fixedly installed at the bottom of the storage box 13 and in the same direction as the top inclined plate. The top inclined plate is placed in front of the bottom inclined plate, and a number of filter holes are also opened on the bottom inclined plate.

[0041] When the present invention is used, the height of the storage box 13 is adjusted by rotating the screw 15 according to the diameter of the steel casing 6 to be ground, so that the storage box 13 can be pressed against the outer wall of the steel casing 6 in a natural state, and then the circular movable frame 4 at the right end is aligned with the right end of the grinding wheel 12 and the steel casing 6 is installed;

[0042] First, the second drive motor is started. The rotation of the output shaft of the second drive motor will drive the grinding wheel 12, the filtering shaft 17 and the circulating water shaft 18 to rotate through the first belt transmission mechanism, the second belt transmission mechanism and the coaxial connection with the filtering shaft 17. First, the outer wall of the steel casing 6 will be continuously polished by the grinding wheel 12, and during the polishing process, the guide blades can be driven to rotate by the rotation of the circulating water shaft 18, and then the filtered water at the bottom of the storage box 13 will enter the left scraper and the right scraper 10 through the water guide pipe 22 and the branch pipe and sprayed to the grinding wheel 12, so as to improve the polishing efficiency and carry the polished debris and solid particles into the storage box 13;

[0043] The water containing solid particles falling into the storage box 13 will be separated by the rotation of the spiral blade 19, and the heavier solid particles will sink to the bottom of the filter barrel and be transported to the sedimentation part at the left end of the filter barrel by the spiral blade 19. The water flow is controlled by the circulating water structure below and flows from the circulation part at the right end of the filter barrel into the storage box 13 below, so as to realize the reuse of water and filter out the polished solid particles.

[0044] At this time, the storage box 13 at the bottom of the filter barrel is still connected to the external pipeline through a pipe, and the pipe can be used to continuously supply clean water to replenish the water in the storage box 13;

[0045] Then, the first drive motor 11 is started, which will drive the steel casing 6 to move horizontally along the axial direction through the meshing of the first gear and the rack 8, and can drive the second gear to rotate through the universal joint coupling, and drive the circular movable frame 4 to rotate around the axis through the meshing of the second gear and the tooth groove, so that the grinding wheel 12 can continuously grind the outer wall of the steel casing 6 circumferentially until it stops at the left end of the steel casing 6.
