[0021] The water filtering device 9 includes a push-pull device 94, and guide plates 95 are slidably connected on both sides of the push-pull device 94. The bottom of the push-pull device 94 is slidably connected to a water storage tank 91, and the inner wall of the water storage tank 91 is fixedly connected to a water outlet pipe 92. The two sides of the top of the water storage tank 91 are fixedly connected to limit plates 93.

The two sides of the water storage tank 91 are fixedly connected to the inner wall of the base 1 through the limit plates 93. The bottom of the workbench 2 is fixedly connected to the top of the guide plate 95. The push-pull device 94 includes a sliding plate 941.

Due to the guiding effect of the guide plate 95 and the gravitational potential energy of the mixed liquid, the mixed liquid enters the trapezoidal filter screen 943 in the waterproof ring 942. Due to the gravity of the mixed liquid itself and the filtering effect of the trapezoidal filter screen 943, the mixed liquid is separated into solid and liquid, with debris remaining in the trapezoidal filter screen 943, and the polishing agent waste liquid falls into the water tank 91 and is discharged from the water tank 91 through the outlet pipe 92.
[0022] Working principle:
[0023] When in use, before grinding and polishing the saw blade, press down the positioning frame 5 and the transparent plate 6. Under the limit of the limit block 8, the lower surface of the positioning frame 5 fits with the upper surface of the base 1. At this time, the positioning frame 5 squeezes the fixed frame 310, and the fixed frame 310 compresses the reset spring 37 through the pressure plate 38 and the fixed plate 39. During the polishing process, the dust suction device 3 is started, and the polishing agent thrown off by the rotating saw blade will hit the water retaining plate 34, and then slide onto the workbench 2. Since the workbench 2 is set with a slope, the polishing position of the saw blade is higher than the two end positions of the inner wall of the base 1. At this time, the polishing agent and debris in the polishing process mix with each other to produce a mixed The liquid is mixed and moved to the position of the leak hole 10. At this time, the debris that is not mixed with the polishing agent solution becomes dust. At this time, the exhaust fan 35 on the positioning bar 31 is started. Due to the flow of air, the dust moves to the exhaust fans 35 on both sides of the base 1 and passes through the dust filter plate 312 at this time. At this time, the dust is blocked by the dust filter plate 312 and collected on the dust filter plate 312. When the positioning frame 5 moves upward, the fixed frame 310 loses the squeezing force, so that the return spring 37 is restored from the compressed state to the state before being squeezed, thereby ejecting the fixed frame 310, making it convenient for the staff to take the fixed frame 310 and replace the dust filter plate 312 that has collected the dust;
[0024] Because the polishing agent will form fine water mist under the high-speed rotation of the saw blade, and the water mist cannot be blocked by the dust filter plate 312, at this time, the water mist passing through the dust filter plate 312 will be blocked by the waterproof curtain 311 on the fixed frame 310, and the water mist condenses on the surface of the waterproof curtain 311. Since the upper and lower ends of the waterproof curtain 311 are fixed on the fixed frame 310, when the left and right sides of the waterproof curtain 311 are not fixed, the exhaust action of the exhaust fan 35 causes the waterproof curtain 311 to shake, thereby shaking off the condensed water mist, and the shaken water mist is re-condensed into polishing agent waste liquid, and falls onto the workbench 2 through the water outlet trough 33 of the positioning strip 31 to re-form a mixed liquid, and the exhaust port of the exhaust fan 35 when exhausting air is directed to the ventilation slot 36 of the positioning strip 31. Since the ventilation slot 36 is connected to the vent pipe 32, the exhausted gas is blown to the leak hole 10 through the vent pipe 32, thereby accelerating the flow of the solution in the leak hole 10 and preventing the flow leak hole 10 from being blocked.
[0025] A water filtering device 9 is provided. When the mixed liquid finally flows to the push-pull device 94 through the guide plate 95 and enters the upper surface of the sliding plate 941, the mixed liquid enters the trapezoidal filter screen 943 in the waterproof ring 942 due to the guiding effect of the guide plate 95 and the gravitational potential energy of the mixed liquid. The mixed liquid is separated into solid and liquid due to the gravity of the mixed liquid itself and the filtering effect of the trapezoidal filter screen 943. The debris is retained in the trapezoidal filter screen 943, while the polishing agent waste liquid falls into the water storage tank 91 and is discharged from the water storage tank 91 through the outlet pipe 92. When it is necessary to collect the debris, it is only necessary to pull out the sliding plate 941 sliding on the limit plate 93 and the water storage tank 91. When the waterproof ring 942 plugged into the sliding plate 941 is removed, the trapezoidal filter screen 943 can be taken out, thereby facilitating the removal of the debris mixed in the polishing agent solution.
[0026] A telescopic rod 4 is provided to drive the positioning frame 5 to move up and down. When the positioning frame 5 moves downward and the bottom finally contacts the upper surface of the base 1, the positioning frame 5, the transparent plate 6, the workbench 2 and the base 1 finally form a relatively closed environment. When the dust collecting device 3 collects the dust, the air in the enclosed space is gradually extracted by the exhaust fan 35. At this time, the air from the external environment enters from the vent 7, and the gas entering through the vent 7 forces the dust to move toward the dust collecting device 3, so that the dust collecting device 3 further enhances the dust collection ability.
[0027] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
