Description

Technical Field

[0001] This invention belongs to the technical field of flotation feeding equipment, specifically a feeding device for flotation columns and its usage method. Background Technology

[0002] A flotation column is an aerated flotation machine that uses compressed air to aerate and agitate the slurry through a porous medium (aerator). There are types such as microbubble countercurrent flotation columns and microbubble jet flotation columns.

[0003] However, in existing technologies, the raw material to be floated is directly injected into the equipment, which results in the raw material rotating inside not being able to fully contact the generated bubbles, leading to low actual screening efficiency. At the same time, the effect of rotation can easily cause the raw material to be screened to be over-concentrated or dispersed in the corners of the equipment, which means that the amount of bubbles provided is insufficient or cannot reach the raw material, thus requiring a longer bubble supply time. This can easily lead to waste of resources and increased production costs, resulting in poor actual performance of existing flotation columns. Summary of the Invention

[0004] The purpose of this invention is to provide a feeding device and its usage method for a flotation column that can improve the actual screening efficiency of existing flotation columns, enable the raw material to be flotated to fully contact with air bubbles, effectively avoid waste of resources, and effectively avoid increasing production costs.

[0005] The technical solution adopted in this invention is as follows: A feeding device for a flotation column, comprising: a first functional mechanism, the first functional mechanism including a connecting pipe and a rotating component, one end of the connecting pipe being threadedly connected to an extension pipe, one end of the extension pipe being threadedly connected to a steering frame, the bottom of the steering frame being threadedly connected to a blocking pipe, the outer surface of the blocking pipe having a plurality of first discharge ports equidistantly arranged, and the rotating component being disposed on the connecting pipe; and

[0006] The second functional mechanism includes two bottom rings, each slidably fitted onto the outer surface of the connecting pipe. Each bottom ring has a set of two fixing rings on its outer surface. An elastic collar is fixedly connected between the two sets of fixing rings. A first clamping ring and a second clamping ring are fixedly connected to one side of the outer surface of each bottom ring. An elastic connecting ring is embedded between the outer surface of each first clamping ring and the inner wall of the corresponding second clamping ring. Three adjusting shafts are equidistantly rotatably connected to one side of the outer surface of one bottom ring. A first adjusting bevel gear is fitted onto the outer surface of one adjusting shaft. A connecting gear and a first connecting bevel gear are fitted onto the outer surface of each adjusting shaft. Three support bars are equidistantly fixed between the opposite outer surfaces of the two bottom rings. An adjusting threaded rod is rotatably connected to the top of each support bar. A sealing block is threaded onto the outer surface of each adjusting threaded rod. A second connecting bevel gear is fitted onto the outer surface of each adjusting threaded rod. Each second connecting bevel gear meshes with a corresponding first connecting bevel gear.

[0007] The rotating component includes a mounting frame that extends through the top of the connecting pipe. A connecting shaft is rotatably connected to the top of the mounting frame. One end of the connecting shaft extends into the interior of the mounting frame. A first bevel gear is fitted on the outer surface of the connecting shaft. A drive motor is fixedly connected to the top of the mounting frame. The output end of the drive motor is fixedly connected to one end of the connecting shaft.

[0008] The mounting frame has an installation tube connected to one side of its outer surface, and a sealing tube connected to the bottom of the installation tube.

[0009] A connecting shaft is rotatably connected between the inner wall of one side of the mounting frame and the inner wall of one side of the mounting tube. A first bevel gear and a second bevel gear are sleeved on the outer surface of the connecting shaft, and the two first bevel gears mesh.

[0010] The inner bottom surface of the sealing tube is rotatably connected to a rotating shaft, and a second bevel gear is sleeved on the outer surface of the rotating shaft. The two second bevel gears mesh, and one end of the rotating shaft extends to the outside of the sealing tube.

[0011] The rotating shaft is fixedly connected to a rotating frame at its bottom end, and the outer surface of the rotating frame is provided with multiple second drain ports at equal intervals.

[0012] The rotating frame is fixedly connected to the bottom of the rotating frame, and multiple guide vanes are equidistantly slidably sleeved on the outer surface of the rotating frame.

[0013] Each of the second clamping rings has a first retaining ring and a second retaining ring rotatably connected to one side of its outer surface, and each of the first retaining rings and the corresponding second retaining rings are fixedly connected at one end by bolts.

[0014] One of the bottom rings has a fixed shaft and an adjusting worm gear rotatably connected to one side of its outer surface. The outer surface of the fixed shaft is fitted with a second adjusting bevel gear and an adjusting worm wheel. The adjusting worm wheel meshes with the adjusting worm gear. The second adjusting bevel gear meshes with the first adjusting bevel gear. A gear ring is slidably fitted on the outer surface of one of the second clamping rings. The gear ring meshes with three connecting gears.

[0015] A method of using a feeding device for a flotation column includes the following steps:

[0016] S1. Equipment Installation: Extend the first functional mechanism into the existing flotation equipment through the feed port, while ensuring that the second functional mechanism can effectively remain inside the feed port. Then, by rotating the adjusting worm, the rotating adjusting worm can drive the corresponding adjusting shaft to rotate through the fixed shaft, the second adjusting bevel gear, and the first adjusting bevel gear. Then, under the action of the gear ring and the connecting gear, the three adjusting shafts can rotate synchronously. Then, the adjusting shaft can drive the corresponding adjusting threaded rod to rotate through the first connecting bevel gear and the second bevel gear. Then, the rotating adjusting threaded rod can move the position of the adjusting sealing block. Then, the sealing block can press the elastic ring to fit against the inner wall of the feed port of the existing flotation equipment. Then, the elastic ring, the bottom ring, and the elastic connecting ring can seal the gap between the connecting pipe and the feed port of the existing flotation equipment.

[0017] S2. Adjusting the screening: The raw material to be floated is connected to the pipeline through the connecting pipe, allowing the raw material to be floated to be injected into the obstruction pipe through the connecting pipe, extension pipe, and steering frame. Under the obstruction of the rotating frame, the raw material to be floated can only be injected into the existing flotation equipment through the first and second discharge ports. When the raw material to be floated reaches an appropriate height inside the existing flotation equipment, the drive motor is started by controlling the start of the drive motor, which drives the rotating shaft to rotate through the connecting shaft and the linkage shaft. The rotating shaft drives the rotating frame to rotate, and the first and second discharge ports are indirectly connected. This allows the raw material to be floated accumulated inside the rotating frame to be squeezed out through the first and second discharge ports. The discharged raw material can effectively impact and mix the raw material to be floated inside the existing flotation equipment at an angle. At the same time, under the obstruction of the guide plate, the degree of liquid agitation in the existing flotation equipment can be slowed down, so that the bubbles can fully screen the raw material to be floated.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] In this invention, during use, the first functional mechanism extends into the existing flotation equipment through the feed port, while ensuring that the second functional mechanism can effectively remain inside the feed port. Then, by rotating the adjusting worm, the rotating worm effectively drives the corresponding adjusting shaft to rotate via the fixed shaft, the second adjusting bevel gear, and the first adjusting bevel gear. Under the action of the gear ring and the connecting gear, the three adjusting shafts rotate synchronously. The adjusting shaft then effectively drives the corresponding adjusting threaded rod to rotate via the first connecting bevel gear and the second bevel gear. This allows the rotating adjusting threaded rod to effectively move the position of the adjusting sealing block, enabling the sealing block to press against the inner wall of the feed port of the existing flotation equipment by squeezing the elastic ring. This allows the elastic ring, bottom ring, and elastic connecting ring to effectively seal the gap between the connecting pipe and the feed port of the existing flotation equipment. This allows the equipment to meet the needs of different existing flotation equipment, improving its versatility. Finally, the raw material to be floated is fed through the connecting pipe. The connection of the channels allows the raw material to be floated to be injected into the blocking tube through the connecting pipe, extension pipe, and steering frame. Under the obstruction of the rotating frame, the raw material can only be injected into the existing flotation equipment through the first and second discharge ports. When the raw material reaches an appropriate height inside the existing flotation equipment, the drive motor is activated, which in turn drives the rotating shaft through the connecting shaft and linkage shaft. This rotating shaft effectively drives the rotating frame, indirectly connecting the first and second discharge ports. The raw material accumulated inside the rotating frame is then squeezed out through the first and second discharge ports. The discharged raw material effectively impacts and mixes the remaining raw material inside the existing flotation equipment at an angle. Simultaneously, the obstruction of the guide vanes effectively reduces the agitation of the liquid in the existing flotation equipment, allowing the bubbles to fully screen the raw material. This enables the existing flotation equipment to efficiently perform its intended functions. Attached Figure Description

[0032] The following provides a detailed description of the method of using a feeding device for a flotation column provided by an embodiment of the present invention, which includes the following steps:

[0033] Step 1: Equipment Installation: Extend the first functional mechanism 1 through the existing flotation equipment's feed port into the existing flotation equipment, while ensuring that the second functional mechanism 2 can effectively remain inside the existing flotation equipment's feed port. Then, by rotating the adjusting worm, the rotating adjusting worm can effectively drive the corresponding adjusting shaft to rotate through the fixed shaft, the second adjusting bevel gear, and the first adjusting bevel gear. Under the action of the gear ring 207 and the connecting gear 209, the three adjusting shafts can rotate synchronously, allowing the adjusting shafts to rotate through the first connecting bevel gear and... The second bevel gear effectively drives the corresponding adjusting threaded rod 212 to rotate, so that the rotating adjusting threaded rod 212 can effectively move the position of the adjusting sealing block 213. In turn, the sealing block 213 can press the elastic ring 202 to fit against the inner wall of the feed port of the existing flotation equipment. In turn, the elastic ring 202, the bottom ring 201 and the elastic connecting ring 208 can effectively seal the gap between the connecting pipe 101 and the feed port of the existing flotation equipment. This allows the equipment to meet the needs of different existing flotation equipment and improves the versatility of the equipment in actual use.

[0034] Step 2, Screening Adjustment: Connect the raw material to be floated via connecting pipe 101, allowing the raw material to be floated to be injected into the blocking pipe 104 through connecting pipe 101, extension pipe 102, and steering frame 103. Under the obstruction of rotating frame 112, the raw material can only be injected into the existing flotation equipment through the first and second drain ports. When the raw material reaches an appropriate height inside the existing flotation equipment, start the drive motor 107, which then drives the rotating shaft 111 to rotate via connecting shaft 106 and connecting shaft 109. The rotating frame 112 can be effectively rotated, allowing the first and second discharge ports to be indirectly connected. This allows the raw material to be floated accumulated inside the rotating frame 112 to be squeezed out through the first and second discharge ports. The discharged raw material can effectively impact and mix with the raw material remaining inside the existing flotation equipment. At the same time, under the obstruction of the guide plate 114, the degree of liquid agitation in the existing flotation equipment can be effectively reduced, allowing the bubbles to fully screen the raw material to be floated. This enables the existing flotation equipment to efficiently perform its intended functions.
