All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0027] like Figure 1 As shown, this embodiment proposes a high-efficiency dehydration device for iron concentrate processing, including an equipment platform 1, a dehydration component 2 for drying iron concentrate is provided on the top of the equipment platform 1, a conveying component 3 for transporting iron concentrate is provided inside the dehydration component 2, and a conveying component 4 for conveying inert gas is provided inside the dehydration component 2.
[0028] like Figure 3 As shown, the dehydration assembly 2 includes a dryer housing 201 fixedly connected to the top of the equipment platform 1. A drying chamber 202 is fixedly connected inside the dryer housing 201, forming a closed space to reduce heat loss and maintain a stable heating environment. Heating wires 203 are installed on the inner wall of the drying chamber 202, with several heating wires 203 arranged opposite each other and evenly distributed. The heating wires 203 can achieve rapid heating, precise temperature control, and improve the dehydration efficiency of the iron concentrate. Several air holes 204 are opened at the top of the drying chamber 202. In use, the dryer housing 201 is fixed to the equipment platform 1, forming the drying chamber 202 inside, providing space for drying the iron concentrate. When the heating wires 203 are energized, heat is generated through the thermal effect of the current, heating the iron concentrate inside the drying chamber 202, causing it to evaporate and discharge moisture through the air holes 204.
[0029] like Figure 3 As shown, the conveying assembly 3 includes a vibrating motor 301 bolted to the top of the equipment platform 1. A conveyor belt 302 is fixedly connected to the output end of the vibrating motor 301. The conveyor belt 302 has a built-in drive motor. The vibrating motor 301 vibrates to prevent the accumulation of iron concentrate. Springs 303 are fixedly connected to the top of the equipment platform 1. Several springs 303 have their ends furthest from the equipment platform 1 fixedly connected to the bottom of the conveyor belt 302. The springs 303 dampen vibrations, reducing equipment wear, extending service life, and minimizing vibration interference to the surrounding environment and other equipment. In use, after the vibrating motor 301 is powered on, the vibration causes the connected conveyor belt 302 to vibrate, preventing the iron concentrate from accumulating or sticking. The drive motor built into the conveyor belt 302 drives the conveyor belt 302 through a transmission device, achieving continuous conveying of iron concentrate. The springs 303 at the top of the equipment platform 1 are connected to the bottom of the conveyor belt 302, providing buffering and damping during vibration, reducing the impact of vibration on the equipment platform 1 and other components.
[0030] like Figure 5 As shown, the conveying assembly 4 includes a centrifugal fan 401 bolted to the side wall of the dryer housing 201. The output end of the centrifugal fan 401 is connected to a conveying pipe 402, which penetrates the side wall of the dryer housing 201. The end of the conveying pipe 402 away from the centrifugal fan 401 is connected to a gas storage tank 403. The gas storage tank 403 contains inert gas. Conveying the inert gas can expel oxygen from the drying chamber 202, preventing the iron concentrate from oxidizing at high temperatures and ensuring product quality. During use, the impeller of the centrifugal fan 401 rotates, giving the internal air kinetic energy and expelling it, creating a negative pressure at the air inlet. This draws the inert gas from the gas storage tank 403 into the conveying pipe 402 and into the drying chamber 202 through the vent 204 at the top of the drying chamber 202.
[0031] like Figure 1 and Figure 4As shown, a dehumidification pipe 5 is connected to the side wall of the drying chamber 202. A dehumidifying fan 6 is installed at the end of the dehumidification pipe 5 away from the drying chamber 202. A humidity sensor 7 is installed on the dehumidification pipe 5 and is electrically connected to the dehumidifying fan 6. During use, the water vapor evaporated from the iron concentrate is discharged through the dehumidification pipe 5 on the side wall of the drying chamber 202. The humidity sensor 7 on the dehumidification pipe 5 monitors the air humidity in real time. When the humidity reaches a set threshold, it sends a signal to the dehumidifying fan 6 to adjust the power of the dehumidifying fan 6 and control the dehumidification speed.
[0032] like Figure 1 As shown, a control panel 8 is installed on the side wall of the dryer housing 201, and the control panel 8 is electrically connected to the heating wire 203. In use, the control panel 8 is electrically connected to all components of the device, and the operator sets parameters such as the temperature of the heating wire 203, the speed of the conveyor belt 302, and the power of the rotating motor 9 through the control panel 8, and monitors the operating status of the equipment in real time.
[0033] like Figure 1 As shown, a rotary motor 9 is bolted to the side wall of the dryer housing 201. The output ends of the two rotary motors 9 are fixedly connected to the centrifugal fan 401 and the dehumidifying fan 6, respectively. In use, the rotary motors 9 drive the centrifugal fan 401 and the dehumidifying fan 6 to operate. The fan impellers rotate, creating a negative pressure at the air inlet or outlet, which draws in the inert gas in the gas storage tank 403 through the conveying pipe 402, or discharges the humid air inside the drying chamber 202 through the exhaust pipe 5.
[0034] like Figure 1 As shown, a shock-absorbing pad 10 is installed at the bottom of the equipment platform 1. The shock-absorbing pad 10 is made of rubber. In use, the shock-absorbing pad 10 is made of rubber material. When the vibration motor 301, centrifugal fan 401 and other components vibrate during operation, the shock-absorbing pad 10 absorbs the vibration energy through its own elastic deformation, reducing the transmission of vibration to the ground and the surrounding environment.
[0035] Specifically, in operation, this high-efficiency dehydration device for iron concentrate processing works as follows: The centrifugal fan 401 impeller rotates by rotating the motor 9, causing the internal air to gain kinetic energy and be discharged. A negative pressure is created at the air inlet, drawing in the inert gas from the gas storage tank 403 through the conveying pipe 402, and then sending it into the drying chamber 202 through the air hole 204 at the top of the drying chamber 202 (e.g., ...). Figure 5 As shown), after the vibrating motor 301 is powered on, the vibration causes the connected conveyor belt 302 to vibrate, preventing the iron concentrate from accumulating or sticking. The drive motor built into the conveyor belt 302 drives the conveyor belt 302 to operate through a transmission device, realizing the continuous conveying of iron concentrate. The spring 303 at the top of the equipment platform 1 is connected to the bottom of the conveyor belt 302, which plays a buffering and shock-absorbing role during vibration, reducing the impact of vibration on the equipment platform 1 and other components (such as...). Figure 3 As shown), the dryer outer shell 201 is fixed to the equipment platform 1, forming a drying chamber 202 inside, providing space for drying iron concentrate. When the heating wire 203 is energized, heat is generated through the thermal effect of the current, heating the iron concentrate inside the drying chamber 202, causing it to evaporate and discharge moisture through the vents 204 (as shown). Figure 3 As shown), during the drying process, the water vapor evaporated from the iron concentrate is discharged through the exhaust pipe 5 on the side wall of the drying chamber 202. The humidity sensor 7 on the exhaust pipe 5 monitors the gas humidity in real time. When the humidity reaches a set threshold, it sends a signal to the dehumidifier 6 to adjust the power of the dehumidifier 6 and control the dehumidification speed (e.g., as shown). Figure 1 and Figure 4 (As shown).
[0036] All technical features in this embodiment can be freely combined according to actual needs.
[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
