Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

The following describes an embodiment of the present invention according to its overall structure.

A coal mill dynamic powder concentrator is shown in figure 1 and comprises a shell 1, wherein two feed inlets 2 are fixedly arranged on the shell 1, and side plates 12 are fixedly connected to the inner walls of the left side and the right side of the shell 1. The coal dust falls by gravity through the feed inlet 12 onto the side plates 12, which is the first time that the coal dust is screened, and then falls by gravity into the crushing assembly 3.

As shown in fig. 1, a crushing assembly 3 is installed in the middle of a casing 1, the crushing assembly 3 comprises a motor 301, a first rotating shaft 302 and a crushing knife 303, when the motor 301 is started, the first rotating shaft 302 at the output end of the motor 301 rotates, and because the first rotating shaft 302 is fixedly connected with the crushing knife 303, the first rotating shaft 302 drives the crushing knife 303 to rotate, so that the falling coal powder is screened for the second time.

Filtering side plate 7 is installed to broken subassembly 3 lower extreme, filters and installs two vibration exciters on side plate 7, and coarse coal powder falls to filtering side plate 7 after the breakage on, and all the other fine coal powder falls to charging tray 9 through filtering side plate 7's hole on, offers a square mouth on the wall of casing 1 left side, filters side plate 7 one side and even on casing 1, and one side is even on square mouth, and passageway 5 one side is even on square mouth, and one side is even on grinder 8's disc 804. When the vibration exciter 10 vibrates, the coarse coal powder immediately rolls out from the square opening, passes through the channel 5 to the disc 804, and immediately enters into the third time for screening the coarse coal powder.

The grinding device 8 comprises a disc 804, a second rotating shaft 801, an upper grinder 802 and a lower grinder 803, wherein one side of the belt 4 is sleeved on the second rotating shaft 801, and one side of the belt is sleeved on the first rotating shaft 302 of the crushing assembly 3. When the motor 301 is started, the first rotating shaft 302 at the output end starts to rotate, the belt 4 and the crushing knife 303 are driven to move simultaneously, the belt 4 drives the second rotating shaft 801 to move, the rotating shaft 801 drives the grinding device 8 to move, and then the coal screening operation for the third time can be performed.

Go up and all install heater 6 in the left and right sides on the grinder 802 inner wall, because the heat conductivity of grinder 8, the heater heats gradually for whole grinder 8 can be dried the buggy. The bottom end of the grinding device 8 is attached with a scattering blade 11, so that the surrounding air quality and the mouth and nose can be effectively protected in the falling process of the pulverized coal. The ground fine coal powder flows to the charging tray 9 through the upper discharge port of the circular disc 804 and the chute of the lower grinder 803, and thus all three coal sieving operations are completed.

The utility model discloses a theory of operation does: first, the motor 301 is started, the first rotating shaft 302 at the output end starts to rotate, the fixedly connected crushing cutter 303 also starts to rotate and do circular motion, and the belt 4 sleeved on the first rotating shaft 302 also drives the second rotating shaft 801 to rotate, so that the whole grinding device 8 also does circular motion. After both devices are ensured to work normally, the pulverized coal is poured in from the two feeding ports 2. Firstly, coal powder falls onto the side plate 12 through the gravity after primary coal screening, then the coal powder enters the crushing assembly 3, the crushing knife 303 makes circular motion, the rotating speed is high, the crushing knife 303 cuts the falling coarse coal powder, and the secondary coal powder screening is performed. The coarse coal powder falls onto the filtering side plate 7 through gravity, and the fine coal powder falls into the charging tray 9 through the holes of the filtering side plate 7. The rest coarse coal powder is vibrated by a vibration exciter 10 on the filtering side plate 7 and rolls down to a disc 804 of the grinding device 8 through the square opening and the channel 5, a heater on the wall of the upper grinder 802 starts working, the coal powder is dried during grinding, the ground coal powder is scattered by blades 11 at the bottom end of the grinding device 8 in the falling process, the surrounding air quality is effectively protected, the opening nose is protected, and then the ground coal powder flows to a charging tray 9 through a discharge port of the disc 804 and a chute of the lower grinder 803, which is used for screening the coal powder for the third time. The screening of the last three times is completed, and the screening work from now on is carried out in the same way, so that the working efficiency is improved to a great extent, the yield and the quality of the pulverized coal are ensured, and the air quality is protected.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various changes or substitutions within the technical scope of the present invention, which should be covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
