Detailed ways

As shown in Figures 1 to 3, the preferred embodiment of the utility model consists of a workbench 12 and a box body 14 which is arranged in front of the workbench 12 and is fixedly connected with the workbench 12. A plurality of through holes 121 are defined on the workbench 12 . The water curtain dedusting device includes a water supply device 5, a water curtain plate 4, an overflow tank 7 and a water tank 9. In the present embodiment, the water supply device 5 is a stainless steel self-priming water pump, but it is not limited thereto. The water curtain plate 4 is located at In front of the workbench 12, the water curtain plate 4 is provided with an air duct baffle device 8 on the opposite side forming the water curtain surface, and the device is composed of a plurality of staggered baffles. One side of the workbench is provided with a spark rebound device 11, which is set to the right side in a preferred embodiment of the utility model, but is not limited thereto. The overflow tank 7 is arranged above the water curtain plate and communicates with the water supply device 5 , and the water curtain plate 4 is connected with the air duct baffle device 8 and is jointly fixed in the box body 14 . Water inlet valve 10 and drain valve 13 are arranged on both sides of water tank 9, water tank 9 is arranged below water curtain plate 4 to accommodate the falling water curtain, and this water tank 9 communicates with water supply device 5 to provide water curtain water source. Water holding tank 9 is also equipped with a liquid level gauge 6, which can show the water level in the lower water tank, so that water can be filled in time when the convenience water is not enough. The present embodiment is provided with suction device 1, filter element 2 and dust collection device 3, and the air outlet of suction device 1 is communicated with primary effect filter core 2 through dust collection device 3, and suction device 1 in the preferred embodiment of the present utility model is Two 2.2KW centrifugal blowers are directly connected, and the dust collecting device 3 is a dust collecting box, but not limited thereto.

Among them, two 2.2KW centrifugal fans 1 provide power for the suction of the whole device, drive the processing dust falling on the workbench to fall through the through hole 121, and make the belt in front of the water curtain or under the through hole of the workbench Dust air enters filter element 2. Two primary effect filter elements 2 further filter the dusty air and discharge clean air. When the grinding table is idle, the dust accumulated by the filter element 2 for a long time is blown by the external airflow and falls into the ash box 3, and the rear maintenance cover can be opened regularly to clean the dust; when the grinding table is working, the ash box 3 is a centrifugal fan directly connected 1 and the ventilation channel between the filter element 2. After the stainless steel self-priming water pump 5 is turned on, the water flows upward into the overflow tank 7 until the water is full, flows out from the overflow tank, and flows downward along the water curtain plate 4 to form a water curtain; The water tank 9 is connected with the stainless steel self-priming water pump 5 to provide water curtain water source, forming a water cycle dust removal system, and a liquid level gauge 6 is installed on one side of the water tank 9, which can display the water level in the lower water tank, so as to facilitate timely water injection when the water is insufficient; The water inlet valve 10 on both sides of the water tank 9 is opened to inject clean water, and the drain valve 13 is opened to discharge sewage, so as to regularly replace the water source required for the normal operation of the machine; The driven water body and larger dust particles prevent direct impact damage to the filter element; the right door is designed with a Mars rebound device 11 to effectively prevent the rebound of large particles of Mars; the punching table 12 is the working area.

Accompanying drawing 4 is a working schematic diagram, and the use process is as follows:

Before grinding the workpiece, press the power button (not marked in the figure) of the grinding table, the power indicator light (not marked in the figure) lights up, the centrifugal direct connection fan 1 and the stainless steel self-priming water pump 5 run, and the centrifugal direct connection fan 1 passes through The channel below the water curtain plate 4 in the box body 14 generates suction to the connecting area above and below the workbench 12. The stainless steel self-priming water pump 5 transports water from the water tank 9 to the overflow tank 7. When the water is full, the water overflows the overflow tank 7 along the The inclined water curtain plate 4 at the front end of the grinding table flows down to form a water curtain, and the water velocity is determined by the power of the water pump 5 .

When grinding the workpiece M, the dust generated is mainly concentrated in the front and right areas of the grinding table, part of the dust in the front splashes out with the water curtain and falls into the lower water tank 9, and part of it passes through the through hole 121 of the workbench 12 and goes directly downward. Fall into the water tank; the dust on the right passes through the spark rebound device and stays on the workbench 12 or directly falls into the water tank through the through hole 121 of the workbench 12; the rest of the dust-laden air flows through the channel below the water curtain plate 4 Through the air duct baffle device 8, it enters the centrifugal fan 1 and discharges to the dust accumulation box 3, enters the primary filter element 2 to filter dust, and discharges the filtered clean air outward.

In summary, the above are only preferred embodiments of the utility model, and are not intended to limit the implementation scope of the utility model. That is, all equivalent changes and modifications made according to the content of the patent scope of the utility model should be within the technical category of the utility model.
