[0038] It can be understood that the feed port 14 can be disposed at any position of the box body 10 , and it is only necessary to allow the material to enter the separation chamber 11 through the feed port 14 .

[0039] In this embodiment, the feed port 14 is disposed on the side of the box body 10 and close to the air inlet, so that the material entering the sorting chamber 11 can be blown through the vertical air supply module 20 at the first time.

[0040] It can be understood that the number of discharge ports 15 can be adaptively set according to the actual sorting requirements of the materials.

[0041] In this embodiment, taking three discharge ports as an example, under the air supply of the vertical air supply module, the particle size of the material gradually decreases from bottom to top, so that large-particle material mainly passes out from the discharge port at the bottom, medium-particle material passes out from the discharge port in the middle, and small-particle material mainly passes out from the discharge port at the top.

[0042] In this embodiment, each discharge port 15 is provided with a filter screen 151, and the filter hole size of each filter screen 151 gradually decreases from bottom to top.

[0045] In this embodiment, the box body 10 is further provided with an observation window 18, which can provide convenience for observing the suspension conditions of the materials in the sorting chamber 11, so as to adjust the frequency of the vertical air supply module 20 and the horizontal air supply module 30 according to the actual conditions.

[0046] In one embodiment, the vertical air supply module 20 includes a vertical blower 21 and an air inlet pipe 22, wherein the air inlet pipe 22 is fixed to the box body 10 and extends to the bottom air inlet 12, and the vertical blower 21 is connected to the air inlet pipe 22 for blowing air into the air inlet pipe 22. Specifically, the vertical blower 21 can supply air to the bottom air inlet 12 by blowing air into the air inlet pipe 22.

[0047] It can be understood that one end of the air inlet pipe 22 close to the bottom air inlet 12 can be extended in the vertical direction to achieve vertical air supply.

[0048] In one embodiment, the air inlet pipe 22 is provided with a plurality of evenly spaced first air holes 221 at one end extending to the bottom air inlet 12, and the first air holes 221 are located on a side of the air inlet pipe 22 close to the sorting chamber 11. Specifically, when the wind enters the end extending from the air inlet pipe 22 to the bottom air inlet 12, it will be distributed to the sorting chamber 11 through the first air holes 221, and a plurality of vertically upward winds will be generated, thereby finally realizing the stratification of the material in the vertical direction.

[0049] In one embodiment, the air inlet pipe 22 is further provided with a plurality of first conical guide members 222, and each of the first conical guide members 222 is respectively connected to each of the first air holes 221 through a small opening. Specifically, the first conical guide member 222 can diffuse the wind passing through the first air holes 221, so that the wind passing through the first air holes 221 can cover the sorting chamber 11.

[0050] In one embodiment, the vertical air supply module 20 further includes a first heater 23, which is installed on the air inlet pipe 22 and is used to heat the gas flowing through. Specifically, the first heater 23 is introduced to heat the gas, so that the vertical air supply module 20 can supply hot air to the air inlet, and the hot air in the vertical direction can dry the material entering the sorting chamber 11, thereby avoiding the material from sticking, thereby facilitating the sorting of the material.

[0051] It can be understood that the first heater 23 can be any heating device such as a heating wire that can heat the gas.

[0052] In one embodiment, the transverse air supply module 30 includes a transverse blower 31 and a second heater 32, the second heater 32 is connected to the side air inlet 13, the transverse blower 31 is connected to the second heater 32, and is used to blow air from the second heater 32 toward each of the discharge ports 15, and the second heater 32 is used to heat the gas flowing through. Specifically, the transverse blower 31 can supply hot air toward each of the discharge ports 15 to the sorting chamber 11 by supplying air to the second heater 32, thereby drying the material in the sorting chamber 11 and facilitating the sorting of the material.

[0053] In one embodiment, the air separation device further includes a plurality of temperature sensors 40 , each of which is located on one side of each discharge port 15 and is used to detect the temperature of the material near each discharge port 15 .

[0054] In one embodiment, the air separation device further includes a distribution plate 50, which is fixed to the side air inlet 13, and the distribution plate 50 is evenly distributed with a plurality of second air holes 51. Specifically, the distribution plate 50 can distribute the gas entering the side air inlet 13 in the horizontal direction through the second air holes 51, so that the gas in the separation chamber 11 is kept uniform in the horizontal direction.

[0055] In one embodiment, the distribution plate 50 is further provided with a plurality of second conical flow guides 52, each of which is connected to each of the second air holes 51 through a small end. Specifically, the gas introduced through the second air holes 51 can be diffused by the flow guiding effect of the second conical flow guide 52, so that the supplied lateral gas can be spread to the entire sorting chamber 11.

[0056] In one embodiment, the air selection device further includes a receiving net 60, which is fixed to the side wall of the bottom air inlet 12 and is located below the feed port 14, and is used to receive the material passed through the feed port 14. Specifically, the material passed through the feed port 14 can be received by the receiving net 60, thereby preventing the material from entering the bottom air inlet 12 and preventing the vertical wind passing through the bottom air inlet 12 from being blocked.

[0057] In this embodiment, the end of the material receiving net 60 away from the feed inlet 14 is inclined toward the bottom air inlet 12. Specifically, the inclination of the material receiving net 60 can facilitate the spreading of materials on the material receiving net 60 and avoid the materials from being concentrated on the end of the material receiving net 60 close to the feed inlet 14.

[0058] In one embodiment, the air selection device further includes a vibration generator 70, which is connected to the material receiving net 60 and is used to drive the material receiving net 60 to vibrate. Specifically, the vibration generator 70 can effectively promote the spreading of materials on the material receiving net 60 by driving the material receiving net 60 to vibrate.

[0059] The specific working principle of the air separation device provided in the embodiment of the utility model is as follows: when the sulfate minerals are separated, the sulfate materials to be separated are introduced into the separation chamber 11 from the feed port 14 and received by the material receiving net 60. The vibration generator 70 drives the material receiving net 60 to vibrate so that the materials are evenly distributed on the material receiving net 60. The vertical blower 21 supplies air to the air duct, and the gas is heated by the first heater 23 and then passes through the first air hole 221 to generate hot air in the vertical direction, and blows the materials on the material receiving net 60 to make the material uniformly dispersed. The material is suspended, and the suspension of the material is observed through the observation window 18. The frequency of the vertical blower 21 is adjusted according to the actual situation. After the temperature of the temperature sensor 40 is stabilized, the transverse blower 31 is started. The wind generated by the vertical blower 21 is heated by the second heater 32, and then passes out from the second air hole 51 to generate transverse hot wind, and finally the materials at different heights in the sorting chamber 11 are blown to each discharge port 15, and after being filtered by each filter screen 151, they are passed out from the discharge port 15 to achieve accurate sorting of sulfate minerals.
