Description

Technical Field

[0001] This utility model relates to the field of phosphate rock processing technology, and in particular to a flotation and desliming device for low-grade phosphate rock. Background Technology

[0002] Desliming before flotation of low-grade phosphate rock is not an optional process, but a crucial pretreatment step that directly determines the success and economics of the entire flotation process. Desliming removes a large amount of muddy gangue that has no recycling value. The main components of this muddy gangue are silicon, aluminum, etc., which are precisely the impurities that need to be reduced in phosphate concentrate.

[0003] Most common low-grade phosphate rock flotation desliming devices use rotating auger blades to propel the ore forward while water washes it, creating intense friction and collision between ore particles and between the ore and the tank walls. This mechanical force effectively crushes and washes away the muddy ore adhering to the surface of the phosphate ore lumps. However, the primary function of the spiral washing machine is washing and conveying. While it can mechanically dislodge most of the agglomerated ore mud, it cannot effectively separate mud from ore. Therefore, a low-grade phosphate rock flotation desliming device is proposed to address these issues. Utility Model Content

[0004] This utility model provides a flotation desliming device for low-grade phosphate rock, including a cylinder, auger blades, and a rotating mechanism. The cylinder is arranged horizontally and connected to a base at its bottom end. The rotating mechanism is located inside the cylinder and also includes multiple agitators and a dewatering mechanism. The cylinder has an hourglass-shaped desliming trough inside. The auger blades and multiple agitators are all connected to the rotating end of the rotating mechanism and are located on the left and right sides of the desliming trough, respectively. The dewatering mechanism is located on the right side of the cylinder, and a rinsing assembly is provided at the top of the cylinder.

[0005] Preferably, the dehydration mechanism includes two frame plates, a dehydration net, a U-shaped frame, a vibration motor, a limiting rod, and a spring. The two frame plates are connected to the right side of the base with a gap between them. The dehydration net is disposed between the two frame plates. The U-shaped frame is connected to the bottom end of the dehydration net. The vibration motor is disposed on the U-shaped frame. The limiting rod is connected to the bottom end of the dehydration net and extends to the bottom of the frame plates. The spring is sleeved on the limiting rod, and its two ends are in contact with the bottom end of the dehydration net and the bottom wall of the frame plate, respectively.

[0006] Preferably, the rotating mechanism includes a motor, a rotating rod, and a fixed plate. The motor is located on the left side of the cylinder, and the fixed plate is connected to the right side of the cylinder. One end of the rotating rod is coaxially connected to the output shaft of the motor, and the other end is rotatably connected to the left side of the fixed plate. The auger blades are coaxially fixedly sleeved on the rotating rod, and multiple agitator rods are connected to the rotating rod.

[0007] Preferably, the top of the cylinder is connected to multiple mounting slots and communicates with the desliming tank.

[0009] Preferably, the bottom end of the cylinder has multiple water outlet holes, which are connected to the desludge dewatering tank.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] By setting up a rotating mechanism to drive the auger blades and multiple agitators to rotate, the auger blades match the shape of the desliming trough when rotating, stirring and transporting the material at the same time. The material is first washed by the flushing component and then stirred by the agitators, which improves the desliming and flushing effect. When the material flows out of the desliming trough to the dewatering mechanism, it undergoes a second flush and then dewatering, making the material desliming more effective. The viscosity of the deslimed slurry is reduced and the fluidity is better. Attached Figure Description

[0016] like Figure 1-2 As shown, the present invention proposes a low-grade phosphate rock flotation desliming device, including a cylinder 1, auger blades 2, and a rotating mechanism. The cylinder 1 is arranged horizontally and connected to a base at its bottom end. The rotating mechanism is located inside the cylinder 1 and also includes multiple stirring rods 3 and a dewatering mechanism. The cylinder 1 has an hourglass-shaped desliming trough inside. The auger blades 2 and multiple stirring rods 3 are all connected to the rotating end of the rotating mechanism and are located on the left and right sides of the desliming trough, respectively. The dewatering mechanism is located on the right side of the cylinder 1, and a rinsing assembly is provided at the top of the cylinder 1.

[0017] In this invention, the desliming tank is hourglass-shaped, consisting of two opposing cones. The right side connects to the right side of the cylinder 1, and the top of the cylinder 1 is connected to a feed hopper for feeding materials into the desliming tank. A rotating mechanism drives the auger blades 2 and multiple stirring rods 3 to rotate. When the auger blades 2 rotate, they stir and transport the material while simultaneously being rinsed for the first time by a rinsing component. Then, the material is stirred by the stirring rods 3, improving the desliming and rinsing effects. When the material flows out of the desliming tank to the dewatering mechanism, it undergoes a second rinse and then dewatering, resulting in a higher desliming effect. The viscosity of the deslimed slurry is reduced, its fluidity is better, and the flotation foam properties are more stable, making the entire flotation process easier to operate and control, and production indicators more stable. A drainage device can be installed below the cylinder 1 according to the size and shape of the cylinder 1 and the dewatering mechanism. This drainage device can be installed through a trough or pipe connection, which is already a very common existing technology.

The spring 66 is sleeved on the limiting rod 65, and its two ends are in contact with the bottom end of the dehydration net 62 and the bottom wall of the frame plate 61, respectively.

[0019] It should be noted that the two frame plates 61 are set opposite each other, the right side of the dewatering net 62 is tilted downward, and the U-shaped frame 63 is used to fix the vibration motor 64.

The fixing plate 43 is on the right side of the cylinder 1, blocking part of the desliming trough. The position below the fixing plate 43 can be used for material discharge, and the material will flow to the dewatering mechanism.
