[0030] Example 1

[0031] See also Figure 1-Figure 2 , this embodiment provides a uniform air flow device for a specific gravity concentrator to improve the convenience of maintenance work.

[0032] In this embodiment, the uniform air flow device of the specific gravity separator includes a support plate 21 fixed to the inside of the shell 10, and ventilation channels 20 are evenly distributed on the support plate 21. A baffle 30 is clamped in the shell 10, and an air distribution pipe 40 that is screwed with the ventilation duct 20 is passed through the baffle 30. The outer end of the air distribution pipe 40 is provided with an air distribution head 41, and the end face of the air distribution head 41 is evenly distributed with air holes 43. The baffle 30 is clamped between the air distribution head 41 and the ventilation duct 20.

[0033] This embodiment uses the ventilation duct 20 to achieve primary uniform air flow. The air in the ventilation duct 20 enters the air distribution duct 40 and flows out through the air holes 43 of the air distribution head 41 to achieve secondary uniform air flow. The air distribution duct 40 is connected to the ventilation duct 20 by means of a screw connection, so that any blocked air distribution duct 40 can be removed separately, thereby improving the convenience of maintenance work.

[0034] In this embodiment, the shell 10 is constructed into a rectangular frame shape, the support plate 21 is welded to the inner wall of the shell 10, the ventilation duct 20 is welded to the support plate 21, the ventilation duct 20 is evenly distributed on the support plate 21, and the ventilation duct 20 and the support plate 21 are maintained in a vertical arrangement; the baffle 30 is slidably engaged with the interior of the shell 10 as a whole, and the baffle 30 and the support plate 21 are maintained in parallel arrangement, the baffle 30 abuts against the end face of the ventilation duct 20, and a mounting hole 31 is provided on the baffle 30 for maintaining a one-to-one correspondence between the ventilation duct 20, and the air distribution duct 40 passes through the mounting hole 31 and is screwed into the ventilation duct 20.

[0035] In addition, the air distribution pipe 40 maintains a one-to-one correspondence with the ventilation duct 20. The air distribution pipe 40 is arranged inside the ventilation duct 20. The air distribution head 41 is integrally formed at the outer end of the air distribution pipe 40, and the outer diameter of the distribution head 41 increases outward from the air distribution pipe 40, that is, the air distribution head 41 is constructed into a cone.

[0036] In addition, the air distribution head 41 is coaxially arranged with the air distribution pipe 40, and an end cover 42 with air holes 43 is screwed on the end face of the air distribution head 41. The air holes 43 are evenly distributed on the end cover 42, and the diameter of the air holes 43 is smaller than the inner diameter of the air distribution pipe 40. After entering the ventilation duct 20, the wind flows into the interior of the air distribution pipe 40 and flows out through the air holes 43 on the end cover 42.

[0037] It should be noted that the baffle 30 is clamped between the air distribution head 41 and the ventilation duct 20, so that the shell 10, the support plate 21 and the baffle 30 form a closed space, which can prevent debris from entering the interior of the shell 10; each air distribution duct 40 is kept independently set, so that any blocked air distribution duct 40 can be disassembled separately, which improves the convenience of maintenance work.

[0038] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
