DETAILED DESCRIPTION
[0019] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.
[0020] A NdFeB passivation device comprises a barrel body 1 with a liquid inlet pipe and a liquid outlet pipe respectively arranged on the upper and lower sides, wherein a motor 12 is arranged at the bottom of the barrel body 1, and a stirring paddle 3 located in the barrel body 1 is arranged on the output shaft of the motor 12:
[0021] A truncated cone-shaped filter cartridge 4 is suspended in the barrel body 1, wherein an annular seat I5 is provided on the outer sleeve of the filter cartridge 4, and the annular seat I5 is connected to the inner wall of the barrel body 1 through a cross bar I6, and a plurality of receiving grooves I with a major arc section are evenly provided on the inner side wall of the annular seat I5, wherein a ball I7 is provided in the receiving groove I, one end of which extends to the outside thereof and abuts against the outer wall of the filter cartridge 4;
[0022] An inlet and outlet 8 is provided on the side wall of the filter cartridge 4 below the annular seat I5, wherein a circular ring 9 is fixed to the top of the filter cartridge 4 through a cross bar II10, and a mesh cylinder 11 whose bottom end abuts against the inner bottom wall of the filter cartridge 4 is screwed into the circular ring 9;
[0023] The top of the filter cylinder 4 is provided with an annular seat II12 located above the mesh cylinder 11, wherein a plurality of receiving grooves II with a major arc cross-section are evenly arranged on the top surface of the annular seat II12, and a ball II13 is arranged in the receiving groove II, one end of which extends to the outside and abuts against the bottom end surface of the top cover plate 14 of the barrel body 1, and an inner tooth ring 15 is also arranged on the inner side wall of the annular seat II12, wherein the inner tooth ring 15 is provided with a gear 16 meshing with it, and the gear 16 is driven by a motor II17 arranged on the cover plate 14.
[0024] like Figure 1 As shown, a boss 18 is provided at the bottom of the filter cartridge 4, wherein a receiving channel which is buckled on the top end of the output shaft of the motor 12 is provided on the bottom end surface of the boss 18.
[0025] In this embodiment, a lifting ring I19 is provided on the inner wall of the filter cartridge 4 above the circular ring 9, and a lifting ring II20 is provided on the top of the cover plate 14.
[0026] In this embodiment, an internal thread is arranged on the inner wall of the ring 9, wherein an external thread screwed to the internal thread is arranged on the outer wall of the net tube 11, and the side walls of the net tube 11 within plus or minus 10 cm above and below the ring 9 are all solid structures, so that threads can be arranged on the side walls.
[0027] like Figure 3 As shown, the side wall of the filter cartridge within the opening of the annular seat 15 is a solid structure, wherein the inner side wall of the annular seat 15 is arranged parallel to the outer wall of the filter cartridge 4.
[0028] like Figure 1 As shown, a handle 21 is provided on the outer wall at the bottom of the net cylinder 11 .
[0029] The method of use of the present invention is as follows: the product is placed in the filter cylinder 4 in the mesh cylinder 11, and the stirring paddle 3 stirs the liquid to make it surge, and the stirred liquid fully contacts the product through the side wall of the filter cylinder 4 and the plurality of apertures on the side wall of the mesh cylinder 11, so as to increase the liquid flow area and make the stirred liquid fully contact the product, thereby improving the processing efficiency and effect of the product;
[0030] After the processing is completed, the liquid is discharged through the liquid outlet pipe. At this time, most of the liquid is drained, but a small amount of liquid is deposited on the filter cylinder 4 and the mesh cylinder 11. Then, the motor II17 drives the gear 16 to drive the inner gear ring 15 to rotate, so as to drive the annular seat II12 to drive the filter cylinder 4, the mesh cylinder 11 and the internal products to rotate at a uniform speed, so as to shake the liquid adhered to the above equipment and make it drip quickly, so as to achieve solid-liquid separation, prevent the equipment components and products from adhering to the liquid after being taken out and polluting the working environment or making it difficult to recover the liquid. During the process, when the filter cartridge 4 rotates, it drives the ball I7 to rotate in the receiving groove I and on the outer wall of the filter cartridge 4, and when the annular seat II12 rotates, it drives the ball II13 to rotate in the receiving groove II and on the bottom of the cover plate 14, so that the rotation of the filter cartridge 4 is not affected. At the same time, the cover plate 14 can also effectively prevent the annular seat II12 and the filter cartridge 4 from moving up by the ball II13, and the annular seat I5 can prevent the filter cartridge 4 from moving down by the ball I7 and limit its swing amplitude, so that the filter cartridge 4 is fixed in the above manner;
[0031] Finally, the cover plate 14 is lifted up through the lifting ring II20, and then the filter cartridge 4 and other components are lifted out of the barrel body 1 through the lifting ring I19. When the product needs to be taken out, it is only necessary to operate the handle 21 through the inlet and outlet 8, and then rotate the mesh cylinder 11 upward to make it rotate upward in the ring 9. Then, the product in the mesh cylinder 11 will immediately flow out through the gap between its bottom end and the bottom wall of the filter cartridge 4. At this time, people can take out the outflowing product through the inlet and outlet 8, so that people do not need to reach in through the top opening of the filter cartridge 4 to take the product out of it, so as to achieve the purpose of facilitating the removal of the product.
[0032] 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.
