[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0028] like Figure 1-Figure 5 As shown:

[0029] An ore drying device provided in an embodiment of the present application includes a circular trough body 1, on which a discharge door 2 is installed.

[0030] A mounting plate 3 which can rotate around the center is mounted on the upper end of the tank body 1 , and a plurality of equidistant and vertically distributed material-moving rods 4 are fixed to the bottom of the mounting plate 3 .

[0031] Furthermore, there is a gap between the lower end of the material moving rod 4 and the inner bottom of the tank body 1 .

[0032] A heating structure 9 is fixed at the bottom of the tank body 1 , and the heating structure 9 is connected to a turning mechanism 10 that can drive the heating structure 9 to turn over.

[0033] In this embodiment, the hot air after heat exchange with the smoke of the submerged arc furnace is transported to the heating structure 9 through the transport pipeline.

[0034] When in use, the hot air is first conveyed to the heating structure 9 through the conveying pipeline, and the heat carried by the hot air is transferred to the tank body 1 to heat the tank body 1. Then, the block ore is conveyed to the tank body 1 through the belt conveyor. At the same time, the mounting plate 3 rotates, and the mounting plate 3 drives all the material-moving rods 4 to rotate synchronously with it. After all the material-moving rods 4 rotate, the material-moving rods 4 drive the ore in the tank body 1 to move, and the ore accumulated in the tank body 1 is flattened. At this time, the heated tank body 1 dries the ore in the tank body 1. During the drying process, the mounting plate 3 is rotated regularly, and the mounting plate 3 rotates. After the movement, all the material-push rods 4 are driven to rotate. After the material-push rods 4 are rotated, the ore in the trough body 1 can be turned over to make the ore evenly heated. After the drying is completed, the air intake work of the heating structure 9 is stopped, and the discharge door 2 is opened. The turning mechanism 10 drives the heating structure 9 to rotate in an inclined distribution, and the trough body 1 is tilted synchronously with the heating structure 9. After the trough body 1 is tilted, the ore in the trough body 1 flows to the position of the discharge door 2 according to its own gravity and is discharged from the discharge door 2. After the discharge is completed, the discharge door 2 is closed, the trough body 1 is reset, and hot air is continued to be supplied to the heating structure 9 to continue the drying work.

[0035] The ore drying device provided in the present embodiment comprises a trough body 1 with a circular structure, a discharging door 2 is arranged on the trough body 1, a mounting plate 3 which can rotate around its center is arranged on the upper end of the trough body 1, a plurality of equally distributed material-discharging rods 4 which extend to the bottom of the trough body 1 are fixed on the mounting plate 3, a heating structure 9 is fixed on the bottom of the trough body 1, and the heating structure 9 is connected to a turning mechanism 10 which can drive the turning thereof, so that when drying the ore, the rotating material-discharging rod 4 can flatten the ore accumulated in the trough body 1, thereby replacing the manual flattening of the ore and reducing the labor intensity of the staff, and in the process of drying, after the material-discharging rod 4 rotates, the ore in the trough body 1 can be turned over, so that the ore is evenly heated, thereby shortening the drying time of the ore and improving the drying efficiency.

[0036] In some embodiments of the present application, a mounting frame is fixed to the trough body 1, and a rotating sleeve 6 concentric with the trough body 1 is rotatably connected to the mounting frame. Specifically, the rotating sleeve 6 passes through the mounting frame and is rotatably connected to the mounting frame through a bearing. The rotating sleeve 6 is connected to a motor 7 that can drive it to rotate. Specifically, the output shaft of the motor 7 extends from the upper end of the rotating sleeve 6 into the rotating sleeve 6 and is fixedly connected to the rotating sleeve 6. The motor 7 is installed on the mounting frame, and the lower end of the rotating sleeve 6 is fixedly connected to the mounting plate 3. Specifically, a U-shaped groove 8 is fixed to the lower end of the rotating sleeve 6, and the U-shaped groove 8 is sleeved on the upper end of the mounting plate 3 and is fixedly connected to the mounting plate 3.

[0037] When in use, the motor 7 drives the mounting plate 3 to rotate through the rotating sleeve 6, and the mounting plate 3 drives all the material-moving rods 4 to rotate synchronously to perform material spreading and turning operations.

[0038] In order to facilitate the replacement of the material-moving rod 4 at a later stage, in some embodiments of the present application, the material-moving rod 4 is detachably fixedly connected to the bottom of the mounting plate 3 .

[0039] In some embodiments of the present application, the heating structure 9 includes a box body 91 with a topless hollow structure, the box body 91 is a circular structure, the upper end of the box body 91 is sealed and welded to the bottom of the trough body 1, and a plurality of partitions 92 in contact with the bottom of the trough body 1 are fixed inside the box body 91, and the plurality of partitions 92 divide the interior of the box body 91 into a serpentine channel 93, one end of the serpentine channel 93 is fixedly connected to an air intake pipe 94, and the other end of the serpentine channel 93 is fixedly connected to an exhaust pipe 95, and the box body 91 is connected to the flipping mechanism 10.

[0040] When in use, the exhaust pipe 95 is connected to the delivery pipeline. After the hot air enters the box body 91, it flows along the serpentine channel 93 to heat the tank body 1. Moreover, after the hot air flows in the serpentine channel 93, the flow time of the hot air and the tank body 1 in the box body 91 can be increased, thereby improving the heat exchange effect between the hot air and the tank body 1.

[0041] In some embodiments of the present application, the air intake pipe 94 and the exhaust pipe 95 are concentrically distributed.

[0042] The flip mechanism 10 includes a frame 101, one end of which is rotatably connected to a hydraulic cylinder 102 via a hinge structure, and the free end of the hydraulic cylinder 102 is rotatably connected to the bottom of the box body 91 via a hinge structure, and the other end of the frame 101 is rotatably connected to the intake pipe 94 and the exhaust pipe 95 at the same time through bearings.

[0043] Furthermore, there are two hydraulic cylinders 102 , and the two hydraulic cylinders 102 act synchronously.

[0044] In this embodiment, the air inlet pipe 94 is rotatably connected to the delivery pipeline via a sealed bearing.

[0045] When discharging, first open the discharging door 2, start the hydraulic cylinder 102, the hydraulic cylinder 102 extends, the hydraulic cylinder 102 pushes the box body 91 to rotate, and the box body 91 drives the trough body 1 to rotate synchronously with it, so that the trough body 1 is tilted. After the trough body 1 is tilted, the ore in the trough body 1 flows to the position of the discharging door 2 according to its own gravity, and is discharged from the discharging door 2. After the discharging is completed, the discharging door 2 is closed, the hydraulic cylinder 102 is shortened, and the trough body 1 is rotated to be horizontally distributed, and then the drying work can continue.

[0046] In some embodiments of the present application, two symmetrically distributed supporting columns 103 are fixed to one end of the frame 101, and after the supporting columns 103 and the box 91 are horizontally distributed, the lower end of the box 91 contacts the upper end of the supporting columns 103, and the supporting columns 103 support the box 91, that is, support the trough body 1, thereby improving the stability of the trough body 1 during drying.

[0047] In some embodiments of the present application, the upper portion of the discharge door 2 is rotatably connected to the trough body 1 via a hinge structure, and the lower portion of the discharge door 2 is detachably and fixedly connected to the box body 91 via a detachable structure 11.

[0048] Specifically, the detachable structure 11 includes an upper mounting ear 111 and a lower mounting ear 112, and a screw 113 which are distributed up and down. The upper mounting ear 111 is fixed to the lower part of the discharge door 2, and the lower mounting ear 112 is fixed to the outer wall of the box body 91. The screw 113 passes through the upper mounting ear 111 and is threadedly connected with the upper mounting ear 111. The lower mounting ear 112 is provided with a socket 114 adapted to the screw 113. The screw 113 can be inserted into the socket 114 to limit the discharge door 2. A knob is fixed to the upper end of the screw 113 to facilitate the staff to rotate the screw 113.

[0049] When opening the discharge door 2, just move the screw 113 out of the socket 114. Since the discharge door 2 is hingedly connected to the trough body 1, after the trough body 1 is tilted, the discharge door 2 is vertically distributed, and a discharge gap is formed between the discharge door 2 and the trough body 1. The ore in the trough body 1 flows out from the discharge gap. After the discharge is completed, insert the screw 113 into the socket 114.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
