Description

Technical Field

[0001] This invention relates to the technical field of flotation mixing equipment, and in particular to a phosphate rock flotation slurry mixer. Background Technology

[0002] Phosphate ore is typically beneficiated using flotation to improve phosphorus grade and recovery rate, meet industrial needs, and protect the environment. Specifically, after the phosphate ore is crushed in a ball mill, the fine slurry enters a mixing tank. Reagents are added to the mixing tank and mixed with the slurry. The resulting slurry is then fed into a flotation machine for flotation.

[0003] The mixing tank is mainly used for stirring before flotation to fully mix the reagents and slurry. However, during the stirring process, the mixture of ore and reagents will splash onto the inner wall and is not easy to clean. At the same time, the slurry, which is a mixture of solid mineral particles and acidic or alkaline flotation solution, will cause corrosion of the mixing tank if it is not cleaned for a long time.

[0004] Therefore, the mixing tank needs to be cleaned regularly. However, the existing mining mixing tanks are large in size, and they are usually manually sprayed with a spray gun after the machine is shut down. The cleaning workload is large and the cleaning efficiency is low. At the same time, the agitator is prone to introducing air bubbles during the mixing process. These bubbles will hinder the full mixing of slurry and reagents, resulting in poor mixing effect. In addition, the existing mining mixing tanks have a wide range of applications and a large stock, making it difficult to replace them with new models.

[0005] Therefore, there is an urgent need for a stirrer to improve the existing mixing tank and solve the above problems based on the existing mixing tank. Utility Model Content

[0006] The purpose of this invention is to provide a phosphate rock flotation slurry agitator to solve the problems existing in the background art.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A phosphate rock flotation slurry agitator includes a mixing tank and an agitator located inside the mixing tank. The mixing tank is provided with a sleeve, scrapers, and a telescopic cylinder. The sleeve has a split structure and is fitted over the agitator and fixed with clamps. The sleeve has locking strips on both sides along the vertical direction. One end of the scraper is provided with a semi-arc-shaped sleeve. The two scrapers are fitted over the sleeve through the two sleeves. The inner side of the sleeve is provided with a groove that matches the locking strip.

[0009] The two telescopic cylinders are symmetrically fixed on the upper sides of the stirring paddle. A semi-circular track is provided below the piston rod of each telescopic cylinder. The top of the ferrule is provided with two sets of symmetrically arranged connecting rods. The top of the connecting rods is provided with rollers, which roll within the semi-circular track.

[0010] Furthermore, the connecting rod has an L-shaped structure, and a universal ball joint is provided at the connection between the roller and the connecting rod.

[0011] Furthermore, the grooves of the semicircular track are oriented towards the axis of the stirring paddle, and the two semicircular tracks are connected into a circle by bolts.

[0012] Furthermore, the length of the sleeve is adapted to the length of the stirring paddle, the clamp is a split structure, the clamp is locked by bolts, and the two clamps are respectively fitted on the upper and lower ends of the sleeve.

[0013] Furthermore, the two sleeves are connected as one unit by bolts, and the scraper is provided with a detachable brush head at one end near the wall of the mixing tank. The length of the scraper is adapted to the radius of the mixing tank.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] See Figures 1-5 This utility model provides a technical solution:

[0027] like Figures 1-5 As shown, a phosphate rock flotation slurry agitator includes an agitator tank 1 and an agitator blade 2 located inside the agitator tank 1. The agitator tank 1 is provided with a sleeve 3, a scraper 4 and a telescopic cylinder 5.

[0028] Through the above technical solutions, such as Figure 1 and Figure 3 As shown, after the agitator 2 stops, the sleeve 3 is fitted onto the agitator 2. Since the sleeve 3 has a split structure, it is easy to install the sleeve 3 onto the agitator 2. At the same time, the sleeve 3 is clamped onto the agitator 2 by two clamps 32 to ensure that the sleeve 3 is installed stably, so that the sleeve 3 and the agitator 2 are fixed together.

[0029] Then, fix the cylinder seat of the telescopic cylinder 5 to the top of the mixing tank 1, with one end of the piston rod of the telescopic cylinder 5 facing the inside of the mixing tank 1. A semi-circular track 51 is provided at one end of the piston rod of the telescopic cylinder 5. After the two telescopic cylinders 5 are installed, align the two semi-circular tracks 51 to form a complete circular track. At this time, the two semi-circular tracks 51 can be fixed with bolts to ensure that the track surfaces of the semi-circular tracks 51 are flush.

[0030] like Figure 1 and Figure 4As shown, the two scrapers 4 are then connected to the sleeve 3. Since one end of the scraper 4 is provided with a semi-arc-shaped retainer 41, the retainers 41 of the two scrapers 4 are joined together to form a circular structure, so that the retainer 41 can be fitted onto the outer wall of the sleeve 3. Since the sleeve 3 is provided with a retaining strip 31 on both sides in the vertical direction, and the inner side of the retainer 41 is provided with a retaining groove that matches the retaining strip 31, the outer sides of the two retainers 41 are connected by bolts, and the inner side of the retainer 41 is slidably connected by the retaining strip 31 and the retaining groove. At this time, the two scrapers 4 are connected as one unit and can slide up and down along the retaining strip 31.

[0031] Meanwhile, the top of the sleeve 41 is provided with two sets of symmetrically arranged connecting rods 54, and the top of the connecting rods 54 is provided with rollers 52. After the two sets of scrapers 4 are installed, the rollers 52 are placed in the semi-circular track 51, which can support the scraper 4 below. At the same time, since the sleeve 3 is fixed to the agitator 2 as a whole, the agitator 2 can drive the sleeve 3 to rotate after it is started. The sleeve 3 drives the scraper 4 to rotate through the snap-fit ​​strip 31 and snap-fit ​​groove 44. Meanwhile, the rollers 52 can rotate along the semi-circular track 51 without affecting the rotation of the scraper 4.

[0032] like Figure 2 As shown, the original drive motor of the stirring paddle 2 can drive the scraper 4 to rotate. The scraper 4 can clean the barrel wall through the brush head 42 set at the end. The length of the sleeve 3 is adapted to the length of the stirring paddle 2, and the extension distance of the telescopic cylinder 5 is adapted to the length of the stirring paddle 2. Therefore, as the telescopic cylinder 5 slowly drives the semi-circular track 51 to move downward, the semi-circular track 51 can drive the roller 52, connecting rod 54, clamp 41 and scraper 4 to move downward together. The clamp 41 is always engaged with the clamping strip 31 through the clamping groove. The rotation of the stirring paddle 2 does not affect the downward movement of the scraper 4. As the telescopic cylinder 5 moves downward, it can clean the deep part of the barrel.

[0033] While the stirring paddle 2 continues to rotate, the roller 52 rotates continuously within the semi-circular track 51. The groove of the semi-circular track 51 is T-shaped, preventing the roller 52 from detaching from it. Simultaneously, the roller 52 is connected to the connecting rod 54 via a universal ball joint 53, facilitating the adjustment of the roller 52's tilt angle and its installation within the semi-circular track 51. The semi-circular track 51 drives the roller 52 and the integrated scraper 4 to move up and down, thus continuously rotating and cleaning the barrel wall.

[0034] Furthermore, such as Figure 5 As shown, the length of the scraper 4 is adapted to the radius of the mixing tank 1. The scraper 4 is provided with a detachable brush head 42 at one end near the tank wall of the mixing tank 1, and a detachable brush strip 43 is provided at the bottom of the scraper 4.

[0035] When the scraper 4 reaches the bottom of the sleeve 3, there is still a certain distance between the scraper 4 and the bottom of the barrel. By installing a detachable brush strip 43 at the bottom of the scraper 4, the brush strip 43 can contact the bottom of the barrel and clean the part of the bottom of the barrel except for the bottom of the blade, which further improves the cleaning effect of the mixing barrel 1 and greatly reduces the amount of manual cleaning work.

[0036] By installing this device onto the existing mixing tank 1 structure, the original mixing tank 1's stirring paddle 2 rotates to clean the tank wall, reducing the labor intensity of manual cleaning and improving cleaning efficiency and effect.

[0037] Meanwhile, this device can also be used in the stirring process. According to the liquid level in the stirring tank 1, the height of the lower edge of the scraper 4 can be adjusted by the telescopic cylinder 5 so that the lower edge of the scraper 4 can just touch the liquid surface. When the stirring paddle 2 mixes the reagent and the slurry, the air bubbles generated on the liquid surface can be scraped off by the scraper 4.

[0038] The scraper 4, through its physical movement close to the barrel wall, can break the bubble film attached to the inner surface of the barrel, accelerate the bubble bursting, and guide the liquid surface to form local turbulence, which promotes the dispersion of bubbles and their entry into the mixing zone with the slurry, thus preventing bubbles from accumulating on the barrel wall for a long time. In synergy with the radial flow of the agitator 2, it can improve the overall mixing efficiency.

[0039] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
