Description

Technical Field

[0001] This utility model relates to the technical field of flotation collection devices, specifically a flotation collection device for potassium sodium feldspar powder. Background Technology

[0002] Potassium-sodium feldspar powder is a powder made from potassium and sodium aluminosilicate minerals. Its main components are potassium feldspar and sodium feldspar. Potassium feldspar and sodium feldspar often occur together, but their potassium and sodium contents differ significantly. It is mainly mined from igneous rocks such as granite and pegmatite. The ore is crushed to millimeter-sized particles and then ground into fine powder by ball milling. Iron minerals and impurities are removed by magnetic separation, desliming and other processes. Potassium feldspar and sodium feldspar are separated by flotation to obtain high-purity potassium-sodium feldspar powder.

[0003] Flotation is the primary method for efficiently separating potassium-sodium feldspar powder and sodium feldspar. The principle of flotation involves adding a collector to make the target mineral surface hydrophobic. This requires mixing the slurry and reagents, adjusting the surface properties, and aerating the slurry. Hydrophobic minerals adhere to the air bubbles and float to the surface, forming a froth layer. The froth layer is scraped off to obtain the concentrate, while the unfloated impurities are discharged as tailings. This process requires at least three electrical devices, resulting in high operating costs and subsequent maintenance costs for the electrical equipment. Therefore, those skilled in the art have provided a flotation collector for potassium-sodium feldspar powder to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a flotation and collection device for potassium-sodium feldspar powder to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a flotation and collection device for potassium-sodium feldspar powder, including a bottom plate, a flotation cylinder, a motor, a pump casing, a rotating shaft, and a stirring shaft. The flotation cylinder is fixed above the bottom plate. The pump casing and the motor are arranged on one side of the flotation cylinder. The upper end of the motor is provided with a rotating shaft rotatably installed inside the pump casing. An impeller rotatably installed inside the pump casing is sleeved on the outer wall of the rotating shaft. A drive wheel is provided at the upper end of the rotating shaft. A stirring shaft is rotatably installed inside the flotation cylinder. A mounting plate is provided at one end of the stirring shaft. An adjusting plate is provided below the mounting plate. A scraper is provided at the lower end of the adjusting plate. A stirring rod arranged in a ring array is provided on the lower outer wall of the stirring shaft. A ring tube is provided inside the lower end of the flotation cylinder. An air supply pipe is installed in connection with the output end of the pump casing. A gas hole arranged in a ring array is provided at the upper end of the ring tube. A driven wheel is provided at the upper end of the stirring shaft. Both the driven wheel and the drive wheel are sleeved with belts.

[0006] Furthermore, a discharge groove is provided on the outer wall of the flotation cylinder, the upper end of the discharge groove is at the same horizontal level as the upper opening of the flotation cylinder, and a guide surface is provided on the inner wall of the discharge groove; Specifically, when the scraper scrapes the foam layer at the top of the flotation cylinder and passes it through the discharge trough, the foam is transported through the discharge trough, and the guide surface plays a guiding role in the flow of the foam.

[0007] Furthermore, a guide channel is provided at the upper end of the base plate, and the height of the guide channel gradually decreases from the front end to the rear end. The guide channel is located below the discharge channel. Specifically, the foam flowing out of the discharge trough through the guide surface is guided and transported through the guide trough.

[0008] Furthermore, a filter screen is provided at the air hole opening, a suction port is provided at the lower end of the pump casing, and the rotating shaft is located at the center of the suction port; Specifically, the filter screen intercepts the upper part of the air vents to prevent solids from entering the annular tube, while the air bubbles discharged from the air vents are separated into several small air bubbles by the filter screen.

[0009] Furthermore, the radius of the driving wheel is smaller than the radius of the driven wheel; Specifically, when the drive wheel rotates, it drives the driven wheel to rotate through the belt, causing the driven wheel to decelerate, which in turn causes the stirring shaft to rotate at a slower speed.

[0010] Furthermore, the mounting plate has a screw hole inside, the upper end of the adjusting plate is provided with a rotating seat, the screw hole is threaded with a screw rod whose lower end is rotatably mounted with the rotating seat, the outer wall of the screw rod is provided with rotating rods distributed in a ring array, the mounting plate is embedded with a sliding sleeve, and the upper end of the adjusting plate is provided with a guide rod that is slidably inserted into the sliding sleeve. Specifically, gripping the screw facilitates the application of rotational force to the screw. The rotational force of the screw acts on the inside of the rotating seat. When the adjusting plate moves longitudinally, it slides inside the sliding sleeve through the guide rod, thus providing longitudinal sliding guidance for the adjusting plate.

[0011] Furthermore, a guide bucket is provided at the lower end of the flotation cylinder, and a discharge pipe controlled by a valve and connected to the guide bucket is provided at the lower end of the flotation cylinder; Specifically, when the tailings are discharged through the guide bucket, the guide bucket acts as a guide, and the valve controls the opening and closing of the discharge pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the motor drives the impeller to rotate through the shaft, the impeller generates negative pressure in the pump casing, draws in air through the suction port and delivers it to the annular pipe, and outputs it through the air hole in the form of dense bubbles inside the flotation cylinder. The drive wheel and the driven wheel are linked to drive the stirring shaft, which drives the stirring rod to stir the slurry. At the same time, the stirring shaft drives the scraper to scrape the foam layer on the surface of the slurry, realizing multiple uses of one machine and reducing the use of electrical equipment and subsequent maintenance costs.

[0017] A flotation and collection device for potassium-sodium feldspar powder includes a base plate 1, a flotation cylinder 3, a motor 4, a pump casing 5, a rotating shaft 6, and a stirring shaft 7. The flotation cylinder 3 is fixed above the base plate 1. The pump casing 5 and the motor 4 are located on one side of the flotation cylinder 3. A rotating shaft 6 is rotatably mounted inside the pump casing 5 at the upper end of the motor 4. An impeller 10, rotatably mounted inside the pump casing 5, is sleeved on the outer wall of the rotating shaft 6. A drive wheel 18 is located at the upper end of the rotating shaft 6. The stirring shaft 7 is rotatably mounted inside the flotation cylinder 3, and a drive wheel 18 is mounted at one end of the stirring shaft 7. Plate 13, an adjustment plate 20 is provided below the mounting plate 13, a scraper 21 is provided at the lower end of the adjustment plate 20, a stirring rod 28 arranged in a ring array is provided on the lower outer wall of the stirring shaft 7, an annular tube 14 is provided inside the lower end of the flotation cylinder 3, an air supply pipe 15 is installed in connection with the output end of the pump casing 5, an air hole 16 arranged in a ring array is provided at the upper end of the annular tube 14, a driven wheel 17 is provided at the upper end of the stirring shaft 7, and belts 19 are sleeved on the outer walls of both the driven wheel 17 and the drive wheel 18. The outer wall of the conveying flotation cylinder 3 is provided with a discharge trough 11. The upper end of the discharge trough 11 is at the same horizontal height as the upper opening of the flotation cylinder 3. The inner wall of the discharge trough 11 is provided with a flow guiding surface 12. A guide channel 2 is provided at the upper end of the base plate 1. The height of the guide channel 2 gradually decreases from the front end to the rear end. The guide channel 2 is located below the discharge channel 11. A filter screen is installed at the opening of the air hole 16, a suction port is installed at the lower end of the pump casing 5, and the rotating shaft 6 is located at the center of the suction port. The radius of the driving wheel 18 is smaller than the radius of the driven wheel 17; The mounting plate 13 has a screw hole 25 inside, and the upper end of the adjusting plate 20 is provided with a rotating seat 24. The screw hole 25 is threaded with a screw 26 whose lower end is rotatably installed with the rotating seat 24. The outer wall of the screw 26 is provided with rotating rods 27 arranged in a ring array. The mounting plate 13 is embedded with a sliding sleeve 23, and the upper end of the adjusting plate 20 is provided with a guide rod 22 that is slidably inserted into the sliding sleeve 23. A guide bucket 8 is provided at the lower end of the flotation cylinder 3, and a discharge pipe 9, which is controlled by a valve and connected to the guide bucket 8, is provided at the lower end of the flotation cylinder 3. In this embodiment, the motor 4 drives the impeller 10 to rotate through the shaft 6. The impeller 10 generates negative pressure in the pump casing 5 and draws in air through the suction port to form a gas-liquid mixture. The mixed gas enters the annular pipe 14 at the lower end of the flotation cylinder 3 through the air supply pipe 15 and is released as uniform microbubbles through the air holes 16. The filter screen divides the large bubbles into small bubbles, increasing the contact area between the bubbles and the slurry. The drive wheel 18 at the upper end of the shaft 6 drives the driven wheel 17 at the upper end of the stirring shaft 7 through the belt 19. Since the radius of the drive wheel 18 is smaller than that of the driven wheel 17, the stirring shaft 7 rotates at a lower speed. The stirring rod 28 fully stirs the slurry, so that the reagents, mineral particles and bubbles are uniformly mixed. Hydrophobic potassium-sodium feldspar particles adhere to the surface of air bubbles and float to the liquid surface with the air bubbles to form a foam layer. The mounting plate 13 at the top of the stirring shaft 7 adjusts the height of the adjusting plate 20 through the screw 26 so that the scraper 21 contacts the foam layer. The rotating scraper 21 scrapes the foam layer into the discharge tank 11. The guide surface 12 guides the foam into the guide tank 2 and finally collects it as concentrate. The impurities that do not float are discharged through the guide bucket 8 and discharge pipe 9 at the bottom of the flotation cylinder 3. By rotating the screw 26, the adjusting plate 20 slides up and down along the guide rod 22, changing the contact depth between the scraper 21 and the foam layer to adapt to different foam layer thicknesses, optimize bubble size, and improve flotation efficiency. Traditional flotation requires multiple devices such as air pumps, mixers, and foam scrapers. This invention achieves air filling, mixing, and foam scraping functions with a single motor 4, significantly reducing energy consumption and equipment costs. The filter screen divides bubbles into micron-level particles, improving bubble utilization and solving the problem of excessively large or unevenly distributed bubbles in traditional air filling devices. The guide surface 12 of the discharge tank 11 and the guide groove 2 of the bottom plate 1 ensure smooth discharge of foam and tailings, reducing residue. Traditional foam scraping devices are fixed and cannot be adjusted, making them unable to adapt to changes in the foam layer. This invention improves flotation accuracy by adjusting the height of the scraper 21 through the screw 26.
