Technical Field
[0001] The invention relates to the field of NdFeB production, and in particular to a gas processing device for NdFeB production. Background Art
[0002] During the production and processing of existing NdFeB magnets, a large amount of dust and magnet powder are often generated. The existing dust removal is often performed by suction through a magnet block, but the dust cannot be removed, so the dust still causes pollution.
[0003] Therefore, there is a dust removal device for the production of NdFeB magnets with patent number CN213590792U, but the device has the following defects when in use, such as: the gas containing dust and magnetic powder enters the water tank through the conduit and contacts the liquid, and then quickly diffuses to the surroundings with the liquid, causing most of the magnetic powder to not continue to move downward in the liquid and contact the magnetic plate, which causes the magnetic plate to not be able to adsorb and clean the magnetic powder well, making it difficult to collect the magnetic powder in the end. Summary of the invention
[0004] The purpose of the present invention is to provide a gas processing device for NdFeB production.
[0005] The technical problem of the present invention is mainly solved by the following technical solutions:
[0006] A gas processing device for NdFeB production, comprising a water tank, wherein a cylinder and a sleeve extending into the interior of the water tank are provided on the top wall of the water tank, wherein a dust removal bag is arranged on the sleeve, a plurality of groups of notches are evenly arranged on the top of the side wall of the cylinder, wherein an air inlet pipe tangentially arranged thereto is provided on the side wall of the cylinder below the notch, a magnetic cylinder is provided inside the cylinder, wherein a protrusion located in the notch is provided on the top outer wall of the magnetic cylinder, and a cover plate sealing the top openings of the two is also provided on the magnetic cylinder and the top of the cylinder, a through hole connected to the air inlet pipe is provided on the side wall of the magnetic cylinder, wherein a guide plate is obliquely provided on the inner wall of the magnetic cylinder on one side of the through hole, a motor is provided on the cover plate, wherein a rotating shaft of the motor passes through the internal opening of the magnetic cylinder, and a magnetic orifice plate located below the cylinder is provided at the bottom end of the rotating shaft, and a plurality of groups of magnetic rods extending into the magnetic cylinder are provided on the top of the magnetic orifice plate.
[0007] Preferably, a water inlet pipe and a water outlet pipe are respectively provided at the upper and lower ends of the water tank side wall.
[0008] Preferably, a manhole is provided on the top wall of the water tank, wherein the liquid level in the water tank is higher than the horizontal plane of the bottom end of the cylinder.
[0009] Preferably, the size of the magnetic tube is adapted to that of the cylinder, and the cross section of the magnetic orifice plate is a cross-shaped structure, wherein the diameter of the magnetic orifice plate is smaller than the inner diameter of the magnetic tube.
[0010] Preferably, a water trap is provided on the water outlet pipe, wherein a sewage pipe is provided at the bottom of the water trap.
[0011] The beneficial effects of the present invention are as follows: the present invention extracts dust through an exhaust fan, so that the dust enters the magnetic cylinder through the air inlet pipe and the through hole. At this time, under the influence of the guide plate, the gas flows to the inner wall of the magnetic cylinder and spirally flows downward, and finally flows into the solution at the bottom of the water tank. In the process of the gas spirally flowing downward on the inner wall of the magnetic cylinder, the magnetic powder mixed therein can fully contact with the inner wall of the magnetic cylinder, thereby achieving the purpose of magnetic attraction of the magnetic powder by the magnetic cylinder, so that the magnetic powder is separated from the gas and the dust; wherein the dust, the gas and a small amount of magnetic powder flow downward into the solution in the water tank, at this time, the motor drives the magnetic orifice plate and the magnetic rod to rotate through the rotating shaft, which can not only play a magnetic separation role on the small amount of magnetic powder contained in the gas flowing out of the magnetic cylinder, but also stir the solution in the water tank so that the dust is fully mixed with the liquid, thereby achieving the purpose of dust removal, and finally the gas is discharged through the sleeve and the dust removal bag. In this process, the dust removal bag can further prevent the gas after dust removal from continuing to be mixed with dust and discharged into the air. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0015] The following are examples and the attached Figure 1-2 , the technical solution of the present invention is further specifically described.
[0016] A gas processing device for NdFeB production, comprising a water tank 1:
[0017] The top wall of the water tank 1 is provided with a cylinder 2 and a sleeve 3 extending to the inside thereof, wherein a dust bag 4 is jacketed on the sleeve 3, a plurality of groups of notches 5 are evenly arranged on the top of the side wall of the cylinder 2, wherein an air inlet pipe 6 tangentially arranged thereto is arranged on the side wall of the cylinder 2 below the notch 5, a magnetic cylinder 7 is arranged inside the cylinder 2, wherein a protrusion 8 located in the notch 5 is arranged on the top outer wall of the magnetic cylinder 7, and a cover plate 9 is also arranged on the top of the magnetic cylinder 7 and the cylinder 2 to seal the top openings of the two, a through hole 10 connected to the air inlet pipe 6 is arranged on the side wall of the magnetic cylinder 7, wherein a guide plate 11 is obliquely arranged on the inner wall of the magnetic cylinder 7 on one side of the through hole 10;
[0018] A motor 12 is arranged on the cover plate 9, wherein a rotating shaft 13 of the motor 12 passes through the inner opening of the magnetic tube 7, and a magnetic hole plate 14 located below the cylinder 2 is arranged at the bottom end of the rotating shaft 13, and a plurality of magnetic rods 15 extending into the magnetic tube 7 are arranged at the top end of the magnetic hole plate 14.
[0019] In this embodiment, a water inlet pipe 16 and a water outlet pipe 17 are respectively provided at the upper and lower ends of the side wall of the water tank 1 , and a water trap 18 is provided on the water outlet pipe 17 , wherein a sewage pipe is provided at the bottom of the water trap 18 .
[0020] like Figure 1 As shown, a manhole is provided on the top wall of the water tank 1, wherein the liquid level in the water tank 1 is higher than the horizontal plane of the bottom end of the cylinder 2.
[0021] In this embodiment, the size of the magnetic tube 7 is adapted to the size of the cylinder 2 , and the cross section of the magnetic orifice plate 14 is a cross-shaped structure, wherein the diameter of the magnetic orifice plate 14 is smaller than the inner diameter of the magnetic tube 7 .
[0022] The method of use of the present invention is as follows: the dust is extracted by the exhaust fan, so that the dust enters the magnetic tube 7 through the air inlet pipe 6 and the through hole 10. At this time, under the influence of the guide plate 11, the gas flows to the inner wall of the magnetic tube 7 and spirally flows downward, and finally flows into the solution at the bottom of the water tank 1. During the process of the gas spirally flowing downward on the inner wall of the magnetic tube 7, the magnetic powder mixed with the gas can fully contact with the inner wall of the magnetic tube 7, thereby achieving the purpose of magnetic attraction of the magnetic powder by the magnetic tube 7, so that the magnetic powder is separated from the gas and dust;
[0023] The dust, gas and a small amount of magnetic powder flow downward into the solution in the water tank 1. At this time, the motor 12 drives the magnetic orifice plate 14 and the magnetic rod 15 to rotate through the rotating shaft 13. One of them can play a magnetic separation role on the small amount of magnetic powder contained in the gas flowing out of the magnetic cylinder 7, and at the same time, it can also stir the solution in the water tank 1 so that the dust is fully mixed with the liquid, thereby achieving the purpose of dust removal. Finally, the gas is discharged through the sleeve 3 and the dust bag 4. In this process, the dust bag 4 can further prevent the gas after dust removal from continuing to be mixed with dust and discharged into the air;
[0024] When the liquid in the water tank 1 is discharged through the outlet pipe 17, if the liquid contains a small amount of magnetic powder, it will accumulate in the water trap 18 under the influence of gravity and finally be discharged through the sewage pipe.
[0025] When in use, the present invention uses the notch 5 to clamp the protrusion 8, so that the through hole 10 can be quickly aligned with the air inlet pipe 6 during the process of inserting the magnetic tube 7 into the cylinder 2, and the notch 5 supports the protrusion 8, which can also smoothly achieve the purpose of suspending the magnetic tube 7 in the cylinder 2. When cleaning, the magnetic orifice plate 14 can be taken out of the water tank 1 for cleaning through the cover plate 9 and the rotating shaft 13, and then the magnetic tube 7 can be pulled out of the cylinder 2 for cleaning.
[0026] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
