[0040] like Figure 1-10 As shown, a high-efficiency dust removal and adsorption device includes an inertial separation mechanism 1, a cyclone separation mechanism 2 and a dust collecting water tank 3, and also includes a dust washing mechanism 4, and the air outlet end of the cyclone separation mechanism 2 is connected to the air inlet end of the dust washing mechanism 4. The inertial separation mechanism 1 includes a hollow box 101, an air inlet pipe 102 and a sedimentation box A103. A serpentine airway 104 is provided inside the hollow box 101, and both ends of the serpentine airway 104 respectively penetrate the hollow box 101. Sealing plates 105 are installed at the positions of both ends of the hollow box 101 corresponding to the serpentine airway 104, which are used to seal the ends of the serpentine airway 104. One of the sealing plates 105 is provided with a plurality of air holes 106 connected to the serpentine airway 104. The air inlet pipe 102 is connected to the hollow box 101 and its bottom end is connected to a plurality of air holes 106. The hollow box 101 is connected to the pore 106; it also includes an air outlet pipe A107, which is fixed on the side of the hollow box 101 and is connected to one end of the serpentine airway 104 away from the air hole 106, and the other end of the air outlet pipe A107 is connected to the air inlet end of the cyclone separation mechanism 2. The sedimentation box A103 is fixed at the bottom end of the hollow box 101, and the bottom surface of the hollow box 101 corresponding to the corner of the serpentine airway 104 is provided with a sedimentation hole 108, and the sedimentation hole 108 is connected to the sedimentation box A103, and the bottom of the sedimentation box A103 is connected to the dust collecting water tank 3 through a trumpet pipe A109. The dust collecting water tank 3, the hollow box 101, the sedimentation box A103 and the cyclone separation mechanism 2 are all fixed on the dust washing mechanism 4.

[0041] The exhaust gas containing metal powder extracted by the air inlet pipe 102 can enter the serpentine airway 104 through the air hole 106. The upper end of the sedimentation hole 108 is chamfered to facilitate the dust to fall into the sedimentation box A103. The metal dust that falls into the sedimentation box A103 can fall into the dust collecting water tank 3 through the trumpet pipe A109 and then settle. The metal dust after sedimentation is not easy to separate from the water in the sedimentation water tank.

[0042] The corner outer wall of the serpentine airway 104 is an arc-shaped structure, and the diameter of the arc structure is greater than the distance between the two parallel inner walls of the serpentine airway 104. A groove 110 is provided in the middle of the arc structure, and the groove 110 and the sedimentation hole 108 in the arc structure are on the same straight line.

[0043] The arc-shaped structure is provided to facilitate the airflow to swirl and change direction therein, and the entrained metal powder will hit the inner wall of the arc-shaped structure due to inertia. The groove 110 can intercept the metal powder, and the intercepted metal powder will fall into the precipitation hole 108.

[0044] The cyclone separation mechanism 2 includes a sedimentation box B201, an air outlet pipe B202 and a conical tube 203. The sedimentation box B201 is a cylindrical structure. The bottom end of the conical tube 203 is inserted into the sedimentation box B201, and the outer walls of the two are sealed. The end of the air outlet pipe A107 away from the hollow box 101 extends toward the conical tube 203, and is inserted into the conical tube 203 and tangent to its inner wall. The bottom end of the sedimentation box B201 is connected to the dust collecting water tank 3 through the trumpet tube B204, one end of the air outlet pipe B202 is connected to the upper end of the conical tube 203, and the sedimentation box B201 is fixed to the dust washing mechanism 4.

[0045] The conical tube 203 is an inverted conical structure, which is similar to the cyclone technology in the prior art, but the bottom of the sedimentation box B201 is connected to the dust collecting water tank 3, so the metal particles after cyclone separation in the conical tube 203 will fall into the sedimentation box B201, and then fall into the dust collecting water tank 3 and settle. No matter how the water flow in the dust collecting water tank 3 is affected by the airflow, the metal powder will not return to the airflow.

[0046] The dust washing mechanism 4 includes an outer barrel 401, an isolation ring 402, a clean water tank 403, a sewage tank 404 and a collecting ring 405. The isolation ring 402 is arranged in the outer barrel 401 and fixedly connected to its inner bottom wall. The two are arranged concentrically. The clean water tank 403, the sewage tank 404 and the dust collecting water tank 3 are all arranged in the isolation ring 402 and fixed on the inner bottom wall of the outer barrel 401. The clean water tank 403 and the sewage tank 404 are connected to the outer barrel 401 and the collecting ring 405 respectively by valve pipes. The clean water tank 403 and the sewage tank 404 are connected to the dust collecting water tank 3. The clean water tank 403 and the sewage tank 404 allow clean water to exist in the cavity between the outer barrel 401 and the isolation ring 402. The collecting ring 405 is a hollow structure, fixed on the inner bottom wall of the outer barrel 401. The upper end of the collecting ring 405 is open, and the upper end corresponds to the circular cavity between the outer barrel 401 and the isolation ring 402. A number of bosses 406 are fixedly installed on the inner bottom wall between the outer barrel 401 and the isolation ring 402. The bottom of the boss 406 is an open structure and is connected to the collecting ring 405. A through hole 407 is provided on the side of the boss 406. The through hole 407 is located on the inner bottom wall of the outer barrel 401. The through hole 407 connects the inner bottom wall of the outer barrel 401 and the collecting ring 405. The end of the air outlet pipe B202 away from the conical pipe 203 extends upward to the side of the outer barrel 401, and the outer wall of the outer barrel 401 is fixedly installed with an expansion pipe 408, and the end of the air outlet pipe B202 away from the conical pipe 203 is connected to the expansion pipe 408, and a plurality of air distribution pipes 409 are installed on the expansion pipe 408, and the other end of the air distribution pipe 409 is inserted between the outer barrel 401 and the isolation ring 402, and is tangent to the arc of the two. A ring plate 410 is provided at the bottom between the outer barrel 401 and the isolation ring 402, and the ring plate 410 is concentrically arranged with the two and is rotatably connected with the two. A plurality of fan blades 411 are fixedly installed on the upper surface of the ring plate 410, and a motor 412 is also fixedly installed on the inner bottom wall of the outer barrel 401 in the isolation ring 402, and the motor 412 is used to drive the ring plate 410 to rotate, and when the motor 412 drives the ring plate 410 to flow clean water around, its direction is opposite to the direction of the air distribution pipe 409. It also includes an air extraction pipe 413 , which is installed on the outer barrel 401 and communicates with the cavity between the outer barrel 401 and the isolation ring 402 .

[0047] The clean water tank 403 is filled with clean water, and the sewage tank 404 is used to extract wastewater containing metal powder. Pumps are installed in the valve pipes of both. The pumps can be remotely controlled or programmed and started regularly. When the water flows between the outer barrel 401 and the isolation ring 402, the precipitated metal powder will contact the boss 406 and then enter the through hole 407. The collection circle 405 itself is already full of clean water, and the powder that falls in is not easily affected by the water flow back.

[0048] When the vacuum pipe 413 vacuums air under negative pressure, the air distribution pipe 409 blows air into the water. When blowing air, the metal powder entrained therein will come into contact with the water flow. Arranging multiple air distribution pipes 409 can expand the air flow area.

[0049] A cover plate 414 is installed on the outer barrel 401 , and the cover plate 414 seals the cavity between the outer barrel 401 and the isolation ring 402 and the cavity in the isolation ring 402 . The air inlet pipe 102 and the air exhaust pipe 413 both pass through the cover plate 414 upwards.

[0050] The hollow box 101 , the sedimentation box A103 and the sedimentation box B201 are all arranged in the isolation ring 402 and fixed on the inner bottom wall of the outer barrel 401 .

[0051] The boss 406 is a conical prism structure, the bottom end of the boss 406 is flush with the inner bottom wall of the outer barrel 401, the interior of the boss 406 is a hollow structure, the through hole 407 is located at the inclined surface of the boss 406, and several bosses 406 are distributed in a circular array at equal distances, and the through holes 407 on the boss 406 are on the same arc line.

[0052] The shape of the boss 406 can make it easier for water to carry metal debris into the collection circle 405 and difficult for water to return from the collection circle 405 .

[0053] An annular track 415 is fixedly installed on the inner wall of the outer barrel 401 and the outer wall of the isolation ring 402, and a plurality of rollers 416 are installed on the inner and outer sides of the ring plate 410. The rollers 416 are stuck in the annular track 415 and can be connected to it in a rolling manner relative to it. The output shaft of the motor 412 is installed with a plurality of conical friction wheels 417. The bottom surface of the ring plate 410 is provided with a plurality of concentrically arranged tooth grooves 418. The conical friction wheels 417 can engage with the tooth grooves 418 and drive the ring plate 410 to rotate.

[0054] There is a gap between the ring plate 410 and the outer barrel 401 and the isolation ring 402 , and metal debris can fall from the gap to the inner bottom wall of the outer barrel 401 .

[0055] A plurality of universal wheels 419 are installed at the bottom of the collecting circle 405 .

[0056] Universal wheels 419 are provided so that the device can be easily moved, or the entire device can be fixed beside the equipment.

[0057] When in use, a hose can be installed on the air inlet pipe 102 for cleaning equipment, or it can be directly installed on the processing equipment. The exhaust pipe 413 is connected to the negative pressure exhaust equipment of the factory. When the gas containing metal powder passes through the inertial separation mechanism 1, the gas can flow along the serpentine airway 104. At this time, the gas needs to turn back at multiple bends when flowing, and the entrained metal powder will hit the corner due to inertia, and most of it will hit the groove 110, so that it will fall into the sedimentation box A103 through the sedimentation hole 108 due to gravity. When there is a certain amount of powder in the sedimentation box A103, the powder will fall into the dust collecting water tank 3, and then the gas containing the metal powder will pass through the conical tube 203 again, and cyclone separation will be performed in the conical tube 203. At this time, the metal powder in the gas will fall into the sedimentation box B201, and then enter the dust collecting water tank 3 again. After the dust falls, it is not easy to be disturbed by the airflow and fly again. After two separations, the metal powder contained in the gas is already less, and then it is washed. In the mechanism 4, the motor 412 can drive the ring plate 410 to rotate, so that the clean water between the outer barrel 401 and the isolation ring 402 can make a circumferential flow movement, and the disturbed clean water can stick to the inner wall of the outer barrel 401, and then when the air distribution pipe 409 blows air, the metal powder contained therein can be washed by the clean water and then enter the clean water. As the clean water rotates, the metal powder passes over the ring plate 410 due to gravity and falls to the inner bottom wall of the outer barrel 401, and then passes through the through hole of the boss 406 as the water rotates. The metal powder falls from the hole 407 into the collecting circle 405. The metal powder in the collecting circle 405 is not easy to return to the outer barrel 401 again. The sewage tank 404 can extract the sewage containing metal powder in the collecting circle 405, and the clean water tank 403 can replenish clean water into the outer barrel 401 at any time. Similarly, the sewage tank 404 can extract the sewage containing dust at the bottom of the dust collecting water tank 3, and the clean water tank 403 can replenish clean water into the dust collecting water tank 3. The pumping and replenishing of water are carried out intermittently, which does not affect the negative pressure suction of the equipment.
