[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides an iron ore concentrate storage device with a built-in drying mechanism, which has the following beneficial effects:

[0020] 1. The iron ore concentrate storage device with a built-in drying mechanism starts the second motor. When the second motor is started, it drives the adjusting rod to rotate. Since the adjusting rod and the middle position of the first connecting block are movably connected by a thread, the adjusting rod is engaged with the middle thread of the first connecting block, so that when the adjusting rod rotates, it drives the first connecting block to move up and down. When the first connecting block moves, it drives the adjusting bin and the first limiting fin to move. The first limiting fin moves in the second connecting groove. When the adjusting bin moves, the adjusting bin moves between the first connecting plates. The connecting limiting block at the bottom of the adjusting bin moves in the first connecting groove outside the heating bin, thereby changing the height of the outer adjusting bin above the heating bin, thereby changing the storage capacity between the heating bin and the adjusting bin. When more iron ore concentrate needs to be stored, it can avoid using multiple storage bins for storage, thereby improving convenience and reducing use costs.

[0021] 2. In the iron ore concentrate storage device with a built-in drying mechanism, when the adjusting bin moves to the highest position, the connecting limit block at the bottom of the adjusting bin reaches the top in the first connecting groove of the heating bin, and at this time, the two first connecting blocks on the outer side of the lower part of the adjusting bin reach below the first limit block and abut against the first limit block, and at this time, the first limit fin on the outer side of the first connecting block reaches the top in the second connecting groove of the connecting bin, which is convenient for limit adjustment and maintaining stability.

[0022] 3. The iron ore powder storage device with a built-in drying mechanism, when the iron ore powder needs to be stored, the cover plate on the top of the regulating bin is opened, and the iron ore powder is poured into the heating bin from the inverted bucket. The iron ore powder will be between the heating bin and the regulating bin, and the iron ore powder is located below the second connecting ring. At this time, the cover plate is closed, the first motor is started, and the heating bin is started to heat the iron ore powder. The first motor drives the first rotating shaft to rotate, and the rotation of the first rotating shaft drives the first stirring rod and the stirring plate to rotate around the first rotating shaft. The rotation of the first stirring rod drives the second stirring rod to rotate around the first rotating shaft. When the first stirring rod and the second stirring rod rotate, the iron ore powder at the edge position of the heating bin is stirred, so as to promote the heating bin to heat the iron ore powder evenly, and promote the even drying of the iron ore powder. When the stirring plate rotates, it will turn over the iron ore powder in the middle position of the heating bin, so as to promote the heating bin to heat the iron ore powder in the middle position evenly, and promote the even drying of the iron ore powder, thereby improving the drying effect of the iron ore powder.

[0023] 4. In the iron ore concentrate storage device with a built-in drying mechanism, when the heating bin heats the iron ore concentrate, the moisture contained in the iron ore concentrate in the heating bin will evaporate upward due to the heat and gather at the first filter plate and the second connecting ring, at which time the second shaft is driven to rotate, and the second limit block and the third shaft are driven to rotate when the second shaft rotates. When the second limit block rotates, it will rotate in the second connecting hole of the first connecting ring to maintain stability, and when the third shaft rotates, it will drive the fan blades to rotate. Since the fan blades in the three vents on one side of the regulating bin are symmetrically distributed with the fan blades in the three vents on the other side, when the six fan blades rotate, the airflow will be discharged from the vents on one side of the regulating bin into the regulating bin and discharged from the vents on the other side of the regulating bin, thereby discharging the moisture at the first filter plate and the second connecting ring, and taking out the moisture in the iron ore concentrate, thereby dehumidifying and drying, preventing the moisture from corroding the iron ore concentrate again, and thus enhancing the dehumidification effect.

The second motor 207 is located between the connecting bin 101 and the adjusting bin 201, and the adjusting bin 201 is movably installed in the middle position of the first connecting plate 112.

[0043] A first filter plate 304 is fixedly mounted on the bottom of the first connecting ring 301 . The first filter plate 304 is provided with evenly distributed first filter holes 305 . The first filter holes 305 can pass moisture but cannot pass iron concentrate.

[0044] A first filter hole 305 is fixedly installed at the bottom of the first filter plate 304, and the first filter hole 305 is fixedly connected to the regulating bin 201. A circle of evenly distributed second filter holes 307 is provided on the first filter hole 305. The second filter holes 307 can pass moisture but cannot pass iron ore concentrate. The second filter holes 307 are located between the first filter plate 304 and the regulating bin 201.

[0045] The exhaust assembly 400 includes a second rotating shaft 401 and a vent 405, a second limit block 402 is fixedly installed at one end of the second rotating shaft 401, a fan blade 404 is fixedly installed at the other end of the second rotating shaft 401, the second limit block 402 is movably installed in the second connecting hole 302, the vent 405 is fixedly installed on the upper part of the adjustment chamber 201, and the fan blade 404 is located in the middle of the vent 405 and four evenly distributed fan blades 404 are fixedly installed.

[0046] Six evenly distributed vents 405 are fixedly installed on the regulating chamber 201, and the fan blades 404 in the three vents 405 on one side are symmetrically distributed with the fan blades 404 in the three vents 405 on the other side. When the six fan blades 404 rotate, the airflow is discharged from the vents 405 on one side of the regulating chamber 201 into the regulating chamber 201 and discharged from the vents 405 on the other side of the regulating chamber 201.

[0047] When in use, the storage capacity of the iron ore fines to be stored can be adjusted through the storage assembly 200 according to the need to store iron ore fines, specifically, the second motor 207 is started, and when the second motor 207 is started, the adjusting rod 205 is driven to rotate. Since the adjusting rod 205 is movably connected to the middle position of the first connecting block 203 through a threaded connection, the adjusting rod 205 is engaged with the middle thread of the first connecting block 203, so that when the adjusting rod 205 rotates, the first connecting block 203 is driven to move up and down, and when the first connecting block 203 moves, the adjusting bin 201 and the first limiting fin 204 are driven to move. The first limiting fin 204 will move in the second connecting groove 111. When the adjusting bin 201 moves, the adjusting bin 201 will move between the first connecting plates 112. The connecting limiting block 208 at the bottom of the adjusting bin 201 will move in the first connecting groove 110 on the outside of the heating bin 109, thereby changing the height of the outer adjusting bin 201 above the heating bin 109, thereby changing the storage capacity between the heating bin 109 and the adjusting bin 201. When more iron ore concentrate needs to be stored, it is possible to avoid using multiple storage bins for storage, thereby improving convenience and reducing use costs.

[0048] When the adjusting bin 201 moves to the highest position, the connection limit block 208 at the bottom of the adjusting bin 201 reaches the top in the first connection groove 110 of the heating bin 109. At this time, the two first connection blocks 203 on the outer side of the lower part of the adjusting bin 201 reach below the first limit block 206 and abut against the first limit block 206. At this time, the first limit fin 204 on the outer side of the first connection block 203 reaches the top in the second connection groove 111 of the connecting bin 101, which is convenient for limit adjustment and maintaining stability.

[0049] When the iron ore fines need to be stored, the cover plate 209 on the top of the regulating bin 201 is opened, and the iron ore fines are poured from the inverted bucket 202 into the heating bin 109. The iron ore fines will be between the heating bin 109 and the regulating bin 201, and the iron ore fines will be located below the second connecting ring 306. At this time, the cover plate 209 is closed, the first motor 108 is started, and the heating bin 109 is started to heat the iron ore fines. The first motor 108 will drive the first rotating shaft 104 to rotate, and the rotation of the first rotating shaft 104 will drive the first stirring rod 105 and the stirring plate 107 to rotate around the first rotating shaft 104. The rotation of the first stirring rod 105 will drive the second stirring rod 106 to rotate around the first rotating shaft 104. When the first stirring rod 105 and the second stirring rod 106 rotate, the iron ore concentrate at the edge position of the heating bin 109 will be stirred, so as to promote the heating bin 109 to evenly heat the iron ore concentrate and promote even drying of the iron ore concentrate. When the stirring plate 107 rotates, it will turn over the iron ore concentrate in the middle position of the heating bin 109, so as to promote the heating bin 109 to evenly heat the iron ore concentrate in the middle position and promote even drying of the iron ore concentrate, thereby improving the drying effect of the iron ore concentrate.

[0050] When the heating bin 109 heats the iron ore concentrate, the water contained in the iron ore concentrate in the heating bin 109 will evaporate upward due to the heat and gather at the first filter plate 304 and the second connecting ring 306. At this time, the second rotating shaft 401 is driven to rotate. When the second rotating shaft 401 rotates, it drives the second limit block 402 and the third rotating shaft 403 to rotate. When the second limit block 402 rotates, it will rotate in the second connecting hole 302 of the first connecting ring 301 to maintain stability. When the third rotating shaft 403 rotates, it will drive the fan blade 404 to rotate. The fan blades 404 in the three vents 405 on one side of 01 are symmetrically distributed with the fan blades 404 in the three vents 405 on the other side. When the six fan blades 404 rotate, the airflow will be discharged from the vents 405 on one side of the regulating chamber 201 into the regulating chamber 201 and discharged from the vents 405 on the other side of the regulating chamber 201, thereby discharging the moisture at the first filter plate 304 and the second connecting ring 306, and taking out the moisture in the iron ore concentrate, thereby dehumidifying and drying, preventing the moisture from corroding the iron ore concentrate again, thereby enhancing the dehumidification effect.

[0051] After the drying and dehumidification is completed, the outside of the ventilation opening 405 can be sealed to prevent moisture in the air from entering, which would cause the iron ore concentrate to be corroded by moisture and affect the quality of the iron ore concentrate.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
