Figures 2 to 4As shown, a plurality of supporting legs are fixed at the bottom of the wet grinding table 1, and the supporting legs are used to provide a supporting effect; specifically, the wet grinding table 1 includes a plurality of outer groove walls 7, a plurality of inner groove walls 8, a grille 11 and a water trough 10, wherein the grille 11 and the water trough 10 are covered on the top of the outer groove wall 7, and the grille 11 is used to support the grinding workpiece to be ground, and the dust generated by grinding enters between the plurality of outer groove walls 7 through the holes of the grille 11, and the plurality of outer groove walls 7 and the plurality of inner groove walls 8 are connected to the plurality of outer groove walls 7. The groove wall 8 forms a U-shaped water storage tank 9, and the U-shaped water storage tank 9 is provided with a first water pipe 41, and the water outlet of the first water pipe 41 is connected with the U-shaped water storage tank 9. After the water in the U-shaped water storage tank 9 overflows, it enters the water flow groove 10. The water flow groove 10 is arranged below the U-shaped water storage tank 9. A vertical side baffle 18 is arranged around the edge of the outer groove wall 7. The vertical side baffle 18 includes a rear baffle 19, a left baffle 20 and a right baffle 21. The multiple inner groove walls 8 include a front baffle 22, a back baffle 23, a left baffle 24 and a right baffle 25. The top edge of the back baffle 23 is fixed with a water guide inclined plate 12. The water overflowing from the U-shaped water storage tank 9 flows to the water flow groove 10 under the guidance of the water guide inclined plate 12. The primary sewage outlet 15 is arranged below the water guide inclined plate 12. When the angle between the water guide inclined plate 12 and the horizontal plane is less than 45 degrees, the flow rate is slow, which easily causes the dust carried by the sewage to compact. When the angle between the water guide inclined plate 12 and the horizontal plane is greater than 65 degrees, the required width of the wet grinding table 1 is larger, so the angle between the water guide inclined plate 12 and the horizontal plane is 45 degrees to 65 degrees.

[0036] Please continue reading Figure 4 Combined with Figure 5 ,like Figures 4 to 5 As shown. The gutter 10 has a plane portion 26 and an arc groove portion 27. The arc groove portion 27 can avoid the existence of a dead corner for dust accumulation. The arc groove portion 27 is close to the back baffle 23, and the plane portion 26 is close to the front baffle 22. Specifically, the gutter 10 is inclined from the left side to the right side and from the front side to the back side, that is, the arc groove portion 27 and the plane portion 26 are inclined from the left baffle 24 to the right baffle 25. The horizontal height of the plane portion 26 is higher than that of the arc groove portion 27, so that the arc groove portion 27 has a low end and a high end, and the primary sewage outlet 15 is arranged at the low end of the arc groove portion 27.

[0037] 2. Water spray dust removal structure 2

[0038] Please continue reading Figure 2 Combined with Figure 6 , Figure 6 The figure is a cross-sectional structural diagram of the movable sewage tank and the spray tank of the utility model.

Figure 7 As shown, the spray plate group 34 includes a plurality of long oblique baffles 37 and short oblique baffles 38. The functions of the long oblique baffles 37 and the short oblique baffles 38 are to allow the sprayed water to collide with the baffles, thereby extending the moving length of the water in the spray box 39, thereby increasing the probability of water and dust combining. In addition, the long oblique baffles 37 and the short oblique baffles 38 are staggered from top to bottom, so that the water dripping from the short oblique baffles 38 can splash onto the long oblique baffles 37 and combine with the dust again, thereby further improving the dust removal effect.
