Description

Technical Field

[0001] The utility model relates to the field of phosphate ore flotation, in particular to an aeration device for a flotation column. Background Art

[0002] Phosphate rock is an important chemical mineral raw material, and column flotation technology is commonly used in its production. Column flotation technology can complete reverse flotation roughing, concentrating, scavenging and other operations in one operation, effectively improving the separation and sorting of carbonate minerals and phosphate minerals and the efficiency of enriching phosphate concentrate. When using flotation columns, corresponding aeration devices are generally required.

[0003] In actual use, the inflator of the flotation column needs to be moved to the desired position. Existing inflators are generally equipped with rollers for movement, but after being moved to the desired position by the rollers, the friction between the bottom of the device and the ground is small and difficult to fix. Therefore, it is easy to move due to the reaction force during inflation and the vibration of the internal machine operation, which may cause the connection between the inflator and the flotation column to fall off, making the stability and safety of the device insufficient. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the inflation device of the flotation column is easily affected by the reaction force during inflation and is easily moved when the internal machine is vibrating, which causes the connection between the inflation device and the flotation column to fall off, resulting in insufficient stability and safety of the device. The utility model provides an inflation device for a flotation column which is not easy to move and has higher stability and safety.

[0005] The technical solution adopted by the utility model is:

[0013] a friction plate fixed to one end of the L-shaped connecting member;

[0014] When the sliding column moves up and down, the friction disc can be folded up or down through the hinge column and the L-shaped connecting piece.

[0015] Further:

[0016] The fixing mechanism further comprises a limiting column, one end of which is fixedly connected to the inner side of the L-shaped connecting piece;

[0017] The chassis is provided with a card slot;

[0018] One end of the limiting column can be inserted into the slot.

[0019] Furthermore, a plug rod is plugged into the card slot.

[0020] Further:

This solves the problem in the prior art that the inflatable device is easily affected by the reaction force during inflation and easily moves when the internal machine is running and vibrating, which causes the connection between the inflatable device and the flotation column to fall off, thereby improving the stability and safety of the device.

[0046] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0047] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0048] See also Figure 1 , Figure 4 The present embodiment provides an aeration device for a flotation column, which mainly includes: a bottom plate 100 , a motor 200 , a fan 300 , a moving mechanism 400 and a fixing mechanism 500 .

[0049] like Figure 1 As shown in the figure, the bottom plate 100 is the main supporting structure of the inflatable device of the flotation column of the present embodiment. Two symmetrical supporting feet inclined toward the middle extend upward from the upper surface of the bottom plate 100, and a circular ring is fixedly arranged between the upper ends of the two supporting feet. The two supporting feet and the circular ring therebetween constitute a supporting ring 120 for fixing the motor 200 to reduce its shaking.

[0050] like Figure 1As shown in the figure, the motor 200 and the fan 300 cooperate to inflate the phosphate ore flotation column, and both are arranged on the upper surface of the bottom plate 100. The motor 200 is fixedly embedded in the support ring 120, and its output end is connected to the fan 300 to power it. A control button 320 is arranged on the outer shell of the fan 300, which is used to control the switch and air supply flow of the fan 300. At the same time, the outer surface of the air outlet end of the fan 300 is provided with an external sleeve 340 to ensure that it is firmly connected to the air inlet end of the flotation column.

[0051] like Figure 1 As shown in , the moving mechanism 400 of this embodiment is composed of four rollers installed at the four corners of the bottom surface of the base plate 100.

[0052] like Figure 1 , Figure 4 As shown in , the fixing mechanism 500 is mainly composed of a cylinder 520, a sliding column 540, two hinged columns 542, two L-shaped connectors 544 and two friction discs 546. The cylinder 520 is cylindrical, can move up and down, and is arranged on the bottom plate 100. Among them, the upper end of the cylinder 520 is open, and two notches 523 are symmetrically provided near the lower end of the side surface, and the lower end is fixedly connected with a chassis 522. The movement of the sliding cylinder 520 can drive the chassis 522 to move, and the bottom surface of the chassis 522 is provided with anti-skid grooves. When the chassis 522 contacts the ground, the friction between the device and the ground is increased to prevent the device from sliding during use. At the same time, the sliding column 540 is slidably embedded in the cylinder 520. The upper end of the sliding column 540 is fixedly connected with a first pull head 548, which is large and cannot enter the cylinder 520. The lower end of the sliding column 540 is hinged to one end of two hinged columns 542. The two hinged columns 542 are symmetrically arranged, and the other ends thereof pass through the two notches 523 on the cylinder 520 and are hinged to the middle of the first sections of the two L-shaped connectors 544. The L-shaped connector 544 is divided into a first section and a second section that are perpendicular to each other. The first section is adapted to the shape of the notch 523 and is embedded in the notch 523 when not in use. The end of the first section is hinged to the bottom of the notch 523; the end of the second section is fixedly connected to the friction disk 546. When the sliding column 540 moves up and down, the friction disk 546 can be folded up or down by the hinged column 542 and the L-shaped connector 544. Figure 1 As shown, when the device is put down, the friction disc 546 is in close contact with the ground, and the bottom surface of the friction disc 546 is provided with anti-skid grooves, which can increase the friction between the device and the ground and make the device more fixed.

[0053] The following is a specific implementation of this embodiment:

[0054] When in use, first push the device to a position near the flotation column. Then press down the first pull head 548 to drive the sliding cylinder 520 to move downward, so that the chassis 522 contacts the ground, and at the same time drive the sliding column 540 to move downward. With the movement of the sliding column 540, the two hinged columns 542 are driven to move downward. Since the other end of the hinged column 542 is hinged on the first section of the L-shaped connecting member 544, and the first section of the L-shaped connecting member 544 is now embedded in the notch 523, the lower end of the hinged column 542 rotates outward to push the L-shaped connecting member 544. Since the end of the first section of the L-shaped connecting member 544 is hinged to the bottom of the notch 523, the L-shaped connecting member 544 will rotate outward around the hinge axis at the bottom of the notch 523, and the friction disk 546 at the other end will gradually drop until it contacts the ground, thereby completing the fixation of the device. Finally, the motor 200 and the fan 300 are started to inflate the inside of the flotation column. After use, first turn off the motor 200 and the fan 300 and cut off the connection with the flotation column, then pull up the first pull head 548, the internal structure of the fixing mechanism 500 moves in the opposite direction to restore to its original position, and at the same time, after the first section of the L-shaped connector 544 is re-engaged in the slot 523, it will continue to move upward to contact the top of the slot 523, and as the sliding column 540 continues to move upward, it drives the sliding cylinder 520 to move upward and restore to its original position. Through the force analysis during use, it is found that the L-shaped connector 544 has a high tendency to break, so it is better to be made of a material with higher strength.

[0055] In this embodiment, by setting the cylinder 520, sliding column 540, hinge column 542, L-shaped connector 544 that are interconnected inside the fixing mechanism 500, the bottom chassis 522 and friction plate 546 that can increase the friction force are controlled to be put away and put down, and the position of the inflatable device during operation is fixed without affecting the movement of the inflatable device, which solves the problem that the inflatable device is easily affected by the reaction force during inflation and the vibration of the internal machine operation, and the connection between the inflatable device and the flotation column is easily disconnected in the prior art, thereby improving the stability and safety of the device. It should also be pointed out that in this embodiment, two fixing mechanisms 500 are set on the bottom plate 100 at the same time to achieve a better fixing effect.

[0056] Preferably, the four rollers in the moving mechanism 400 of this embodiment can be universal wheels. Universal wheels can be turned freely and move more flexibly, but they also have the disadvantage of making the device easier to move and more unstable when working. However, in the inflation device of the flotation column of this embodiment, due to the fixing effect of the fixing mechanism 500, the stability of the device as a whole will not be affected by the disadvantages of universal wheels. The universal wheels can make the movement of the device more convenient, making it easier for the staff to move the device, effectively improving the convenience and practicality of the device.

[0057] In the above embodiment, since the bottom plate 100 is moved and fixed on the ground by rollers, it is set at a low position, which makes it inconvenient for the user to move the inflatable device, and it is also difficult to keep the device stable and not slip before fixing. In order to solve these problems, a second embodiment is further proposed based on the first embodiment.

[0058] See also Figure 2 , Figure 3 The inflatable device of the flotation column in the second embodiment mainly adds two push rods 160 on the bottom plate 100. The push rods 160 are parallel L-shaped rods, and the corner positions are bent rod transitions; one end of the shorter horizontal rod portion below is fixed to the side of the bottom plate 100. A horizontal handle 162 is fixedly connected between one end of the longer vertical rod portion on the two push rods 160. The handle 162 is set at a suitable height to facilitate the user to exert force with his hand when standing to push or stabilize the inflatable device. In this embodiment, the convenience and practicality of the device are effectively improved by setting the push rod 160 and the handle 162.

[0059] At the same time, if Figure 2 , Figure 3 As shown in , in order to prevent the user from accidentally hitting the vertical rod of the push rod 160 from the side close to the bottom plate 100 when operating the inflatable device, causing the device to fall. In the second embodiment, a cover body 140 and four fixing rods 142 are also added to the bottom plate 100. The four fixing rods 142 are vertically fixedly connected to the four corners of the upper surface of the bottom plate 100, and the upper ends of the four fixing rods 142 are fixedly connected to the horizontal cover body 140. On the one hand, the height of the cover body 140 is close to the height of the handle 162, and occupies the space close to the side of the bottom plate 100. Through the arrangement of the fixing rod 142 and the cover body 140, the push rod 160 can be prevented from being hit and causing the device to fall, thereby improving the safety of the device. On the other hand, the fixing rod 142 and the cover body 140 surround the motor 200, the fan 300 and the upper end of the fixing mechanism 500, which can protect the device, prevent the device from being damaged by collision, and increase the service life of the device. Furthermore, the gaps between the four fixing rods 142 also reserve operating space for the control buttons 320 on the fan 300 and output space at the air outlet of the fan.

[0060] Preferably, if Figure 2 , Figure 3 As shown in the figure, the two push rods 160 and the fixing mechanism 500 can also be arranged on the same side of the base plate 100, thereby forming a protective layer for the fixing mechanism 500 through the two push rods 160 to prevent the relatively slender fixing mechanism 500 from being damaged, and the hollow part between the two push rods 160 will not affect the user's operation of the fixing mechanism 500 when fixing the inflatable device.

[0061] The second embodiment solves the practicality and safety issues of the flotation column inflation device on the basis of the first embodiment. However, there are other areas of improvement in the flotation column inflation device in the above embodiment. Since the fixing mechanism 500 and the bottom plate 100, and the cylinder 520 and the sliding column 540 in the above embodiment are all slidably connected, the fixing state and position of the fixing mechanism 500 itself are not stable, and it is easy to loosen, resulting in the failure of its fixing effect on the entire inflation device.

[0062] Therefore, in the third embodiment, several structures with limited position are further added to keep the fixing state of the fixing mechanism 500 stable. Figure 4 In the third embodiment, a limiting column 560 and a limiting rod 580 are mainly provided on the fixing mechanism 500.

[0063] like Figure 4 As shown in , one end of the limiting column 560 is fixedly connected to the middle of the lower surface of the second section of the L-shaped connecting member 544, and the other end thereof moves with the movement of the L-shaped connecting member 544. When the fixing mechanism 500 completes the fixed state, the other end of the limiting column 560 contacts the upper surface of the chassis 522, and two side-by-side vertical plate-shaped structures are provided at the contact position to clamp the limiting column 560. At the same time, corresponding through holes are provided on the clamping groove 562 and the limiting column 560. In the fixed state, a plug rod 564 is inserted therein. In this embodiment, a second pull head 566 is provided at one end of the plug rod 564, and a first spring 568 is sleeved on the plug rod 564, one end of which abuts against the inner side of the second pull head 566, and the other end of which abuts against the outer side of the clamping groove 562.

[0064] like Figure 4 As shown in , the limiting rod 580 passes through the limiting block 105 and is slidably arranged on the upper surface of the bottom plate 100, and a third pull head 582 is arranged at one end of the limiting rod 580. A second spring 584 is also sleeved on the limiting rod 580, one end of which abuts against one side of the limiting rod 580, and the other end of which abuts against the inner side of the third pull head 582. At the same time, a first limiting hole 525 is arranged on the side of the cylinder 520, and a second limiting hole 545 is also arranged on the side of the sliding column 540. In the fixed state, the first limiting hole 525 and the second limiting hole 545 both correspond to the position of the limiting rod 580. By sliding the limiting rod 580, the first limiting hole 525 and the second limiting hole 545 can be passed through at the same time, so that the cylinder 520 and the sliding column 540 are kept fixed on the bottom plate 100.

[0065] In the third embodiment, after the fixation is completed, the limiting column 560 is clamped in the card slot 562, and the insertion rod 564 is passed through the two, so that the structure of the hinge column 542, the L-shaped connecting member 544 and the friction disk 546 is stable; at the same time, the limiting column 560 is passed through the cylinder 520, the sliding column 540 and the limiting block 105, so that the position of the cylinder 520, the sliding column 540 and the bottom plate 100 relative to each other is stable. In summary, in this embodiment, the fixing state and position of the fixing mechanism 500 itself can be kept stable, avoiding its loosening and failure, which affects the fixing effect of the inflatable device. At the same time, the setting of the first spring 568 and the second spring 584 in this embodiment respectively avoids the insertion of the insertion rod 564 and the limiting rod 580 too deep, making it difficult to pull out the second slider 566 and the third slider 582.
