[0016] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] Embodiment: A water curtain type grinding room for processing sheet metal parts, such as Figure 1 and Figure 2 As shown, it includes a grinding room body 1, a grinding chamber 2 and a filtering processing chamber 3 are arranged inside the grinding room body 1, a bottom plate 4 is arranged between the filtering processing chamber 3 and the grinding chamber 2, and a plurality of filtering sieve holes 5 are arranged on the bottom plate 4. The gas mixed with impurities generated in the grinding chamber 2 is transported to the filtering processing chamber 3 through the filtering sieve holes 5 for filtering processing.

[0018] A spray conduit 6 is provided in the filtering processing chamber 3 below the bottom plate 4, and a plurality of liquid outlet nozzles 7 cooperating with the filtering sieve holes 5 are provided on the spray conduit 6. The liquid outlet nozzle 7 includes a vertical conduit 8 fixed to the spray pipe and a rotating nozzle 9 movably connected to the vertical conduit 8. The vertical conduit 8 is penetrated in the filtering sieve holes 5, and the rotating nozzle 9 is plugged into the filtering sieve holes 5. A driving gas rod 10 for driving the vertical movement of the spray conduit 6 is provided on the side wall of the filtering processing chamber 3, that is, the vertical movement of the spray conduit 6 can be driven under the control of the driving gas rod 10. The dark groove 20 embedded in the gas rod 10 drives the gas rod 10 to always maintain the vertical expansion and contraction in the dark groove 20, reducing the possible interference with the operation of other components of the filtering and processing chamber 3, and steadily realizing the relative movement between the rotating nozzle 9 and the filtering sieve hole 5, that is, when the grinding environment in the grinding chamber 2 is normal, the engagement between the rotating nozzle 9 and the filtering sieve hole 5 is satisfied. When the environmental impurity content in the grinding chamber 2 is too high and needs to be purified and filtered, the spray conduit 6 is moved upward under the drive of the driving gas rod 10, so that the rotating nozzle 9 extends out of the filtering sieve hole 5, which is convenient for starting the water spray purification action. The side wall of the filtering and processing chamber 3 is also provided with an auxiliary groove 18 for sliding one end of the spray conduit 6 away from the water pump body 11, which further improves the smoothness and stability of the overall vertical position adjustment of the spray conduit 6.

[0019] Taking into account the high degree of fit required between the rotating nozzle 9 and the filter screen hole 5, a step groove 21 is provided at the opening of the filter screen hole 5, and a step block 22 cooperating with the step groove 21 is provided at the bottom of the rotating nozzle 9, thereby improving the stable switching effect of the working opening and closing state of the filtering processing chamber 3.

[0020] A water pump body 11 connected to the spray conduit 6 is provided on the outside of the grinding room body 1. The water pump body 11 and the spray conduit 6 are connected by a hose. Under the continuous high-pressure water supply of the water pump body 11, the rotating nozzle 9 can wet the air in the grinding chamber 2 with water, and adsorb and deposit a large amount of impurities. An inclined guide plate 12 is also provided in the filtering processing chamber 3 under the bottom plate 4. The water flow adsorbed with impurities flows down from the filtering sieve hole 5 to the inclined guide plate 12. An air outlet 13 is provided on the inclined guide plate 12. A portion of the water mixed with impurities flows out along the inclined guide plate 12, and a portion flows downward from the air outlet 13. Simultaneously, a large amount of gas is continuously transported along the air outlet 13. A sedimentation treatment chamber 14 cooperating with the inclined guide plate 12 is provided at the bottom of the filtration treatment chamber 3. The sedimentation treatment chamber 14 can collect and purify the water flowing down the inclined guide plate 12. The sedimentation treatment chamber 14 is connected to the water pump body 11, and the purified water is returned to the water pump body 11 for the water curtain spraying process, meeting the design requirements of environmentally friendly and water-saving equipment.

[0021] An air inlet 15 is arranged on the wall of the filtering and processing chamber 3 located below the inclined guide plate 12, and an air duct filter device 16 connected to the air inlet 15 is arranged on the outer side of the grinding room body 1. By utilizing the flow guidance of the air duct filter device 16, a negative pressure diversion of the gas in the grinding chamber 2 is always formed. A plurality of purification sponge blocks 23 are arranged in the filtering and processing chamber 3 below the inclined guide plate 12, which can meet the filtering and dehumidification of the passing gas and ensure that a large amount of gas to be purified is sucked out of the filtering and processing chamber 3. An air inlet 17 connected to the air duct filter device 16 is arranged at the top of the grinding chamber 2, and the gas to be purified is returned to the grinding chamber 2, meeting the requirements of a reliable processing and production environment. A spoiler baffle 19 is arranged at the air inlet 17, which ensures the stable and uniform input of the replacement air while also reducing the reflux phenomenon of the airflow in the grinding chamber 2, which helps to reduce the impurity gas in the grinding chamber 2 from entering the air inlet 17.
