AI Technical Summary
In existing high-purity quartz sand flotation devices, the lowest point of the scraper of the scraping component maintains a constant distance from the initial highest liquid level in the flotation tank. This results in impurities not being effectively scraped off when the liquid level drops, creating gaps that affect flotation purity and easily lead to scaling.
The system employs an adjustment and scraping assembly. A rotating drive unit moves the lead screw and guide block up and down, adjusting the distance between the scraper and the liquid surface in real time to ensure that the lowest point of the scraper is always in contact with the liquid surface. Combined with the stirring assembly, it generates a stable foam layer to prevent impurities from accumulating.
It achieves continuous and thorough removal of impurities, avoids reduction in flotation purity and scaling on the tank walls, and improves flotation efficiency and purity.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of flotation equipment technology, and in particular to a novel flotation machine for quartz sand. Background Technology
[0002] In the existing high-purity quartz sand flotation process, a fixed scraping assembly is used at the outlet of the flotation tank to continuously scrape and remove flotation impurities from the liquid surface. The lowest point of the scraper of this assembly is kept at a constant distance from the initial highest liquid level in the flotation tank, and the installation position of the scraper cannot be adjusted throughout the entire flotation process. As the flotation reaction continues, impurities are continuously carried to the liquid surface by air bubbles and discharged, and the liquid level gradually decreases. However, the fixed scraper cannot move down accordingly, causing its lowest point to eventually detach from the liquid surface, resulting in a gap between the scraper and the liquid surface. At this time, the flotation impurities cannot be effectively scraped off and remain on the upper layer of the liquid surface, which not only reduces the flotation purity but also easily forms scale on the inner wall of the tank, affecting subsequent batch production. Therefore, it is urgent to improve the existing fixed scraping structure. Utility Model Content
[0003] The purpose of this invention is to provide a new type of flotation machine for quartz sand, which solves the problem mentioned in the background art that the scraping component of the existing flotation device maintains a constant distance between the lowest point of the scraper and the initial highest liquid level in the flotation tank, and the scraper installation position cannot be adjusted throughout the flotation process, resulting in the inability to scrape off impurities when the liquid level drops.
[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0009] A scraping assembly, which is disposed on the adjusting assembly, is used to scrape impurities from the top of the liquid surface in the flotation tank into the impurity collection tank;
[0010] The adjustment assembly includes symmetrically and fixedly mounted grooved rods on the upper wall of the flotation tank.

One end of the lead screw is fixedly connected to a connecting shaft, and one end of the connecting shaft is rotatably connected to a side wall inside the cavity. One end of the grooved rods is fixedly connected to a rotary drive component. A through hole communicating with the cavity is opened on one side wall of the grooved rods.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1:
[0025] Please see Figures 1-4 As shown, this utility model is a novel flotation machine for quartz sand, comprising:
[0026] Flotation box 1;
[0027] Impurity collection tank 2, which is disposed on one side of flotation tank 1;
[0028] Adjustment components, two sets of the adjustment components are arranged above the flotation tank 1, and are used to adjust the position of the scraping component;
[0029] A scraping assembly, which is disposed on the adjusting assembly, is used to scrape impurities at the top of the liquid surface in the flotation tank 1 into the impurity collection tank 2;
[0030] The adjustment assembly includes symmetrically arranged and fixedly mounted groove rods 3 on the upper wall of the flotation tank 1. The upper wall of the groove rods 3 has a cavity, and a lead screw 4 is provided inside the cavity. One end of the lead screw 4 is fixedly connected to a connecting shaft 5, and one end of the connecting shaft 5 is rotatably connected to a side wall inside the cavity. One end of the groove rods 3 is fixedly connected to a rotary drive component 6. A through hole communicating with the cavity is provided on a side wall of the groove rods 3. The output end of the rotary drive component 6 passes through the through hole and is fixedly connected to the other end of the lead screw 4. A guide block 7 is slidably connected inside the cavity, and the guide block 7 is movably connected to the outer wall of the lead screw 4.
[0031] Specifically, to ensure synchronous driving of the two rotary drive components 6, a PLC is installed as a central controller. One of its high-speed pulse outputs is simultaneously connected to the servo drivers of the two rotary drive components 6, enabling their respective servo motors to complete the lifting and lowering actions of the same angle, speed, and direction under the same time reference. At the same time, a synchronous encoder feedback line is added between the two servo drivers to cross-compare the actual rotation angle in real time. When the position deviation of either servo motor is greater than ±0.2mm, the PLC immediately triggers the deviation compensation algorithm to dynamically fine-tune the pulse count, thereby ensuring that the two sets of lead screws 4 and guide blocks 7 are always in an absolutely synchronized state, realizing the horizontal and stable lifting and lowering of the scraping component.
[0032] As can be seen from the above, the rotary drive component 6 drives the guide block 7 to rise and fall via the lead screw 4, so that the distance between the scraper 13 and the liquid surface can be adjusted in real time. This ensures that the lowest point of the scraper 13 is always in contact with the gradually decreasing liquid surface, avoiding the "empty scraping" dead angle caused by the drop in liquid level in the fixed structure, ensuring that impurities are continuously and thoroughly pushed into the impurity collection tank 2, and preventing the reduction of flotation purity and scaling on the tank wall.
[0033] Depend on Figure 2 and Figure 4 It is understood that the scraping assembly includes an adapter seat 8 fixedly mounted on one of the guide blocks 7, a bearing block 9 fixedly connected to the other guide block 7, a motor 10 fixedly connected to one side wall of the bearing block 9, a bearing hole opened on one side wall of the bearing block 9, a horizontal shaft 11 rotatably connected inside the bearing hole, one end of the horizontal shaft 11 rotatably connected to one side wall of the adapter seat 8, the output end of the motor 10 fixedly connected to the other end of the horizontal shaft 11, and several support rods 12 fixedly connected to the outer wall of the horizontal shaft 11, with a scraper 13 fixedly connected to one end of each support rod 12.
[0034] The scraper 13 has a rectangular plate structure.
[0035] As can be seen from the above, the motor 10 drives the horizontal shaft 11 to rotate, and the support rod 12 drives multiple rectangular scrapers 13 to perform circumferential scraping motion. When the scraper 13 contacts the liquid surface at the lowest point, it forms a lateral push sweep. Since the guide block 7 can move down synchronously with the liquid level, each scraper 13 always maintains the same effective scraping depth, which not only improves the scraping efficiency but also avoids omissions caused by liquid surface fluctuations.
[0036] Example 2:
[0037] refer to Figure 1 , Figure 2 and Figure 3 As shown, the flotation tank 1 is equipped with a stirring assembly. The stirring assembly includes a mounting frame 14 fixedly installed on the upper wall of the flotation tank 1. A bearing ring 15 is fixedly connected to the mounting frame 14. A vertical shaft 16 is rotatably connected inside the bearing ring 15. A turbulence stage 17 is fixedly connected to the lower end of the vertical shaft 16. Several turbulence plates 18 are fixedly connected to the bottom wall of the turbulence stage 17.
[0038] Several of the aforementioned spoilers 18 are arranged in a circumferential array on the bottom wall of the spoiler platform 17.
[0039] A support plate 19 is fixedly connected to the upper wall of the flotation tank 1. A motor 20 is fixedly connected to the support plate 19. A connecting shaft 21 is fixedly connected to the output end of the motor 20. A first pulley 22 is fixedly connected to the outer wall of the connecting shaft 21. A second pulley 23 is fixedly connected to the upper outer wall of the vertical shaft 16. An associated belt 24 is sleeved on the outer walls of the first pulley 22 and the second pulley 23.
[0040] Specifically, the bubble generation inside flotation tank 1 adopts existing technology and equipment. The bubbles inside flotation tank 1 can be generated by setting up a continuous air supply-microbubble generation system: the compressed air in the plant area is stabilized to 0.15–0.25MPa by a pressure reducing valve and then enters the dissolved air tank, where it is fully mixed with water at 0.3–0.4MPa to form supersaturated dissolved air water; this dissolved air water is transported through pipelines to multiple sets of microbubble releasers evenly distributed at the bottom of the tank. At the moment of sudden decompression, air is released and sheared and swirled by the micropores inside the releasers to generate uniform microbubbles of 20–100μm.
[0041] As can be seen from the above, the motor 20 drives the vertical shaft 16 to rotate via the pulley pair, and the turbulence table 17 drives the circumferential array of turbulence plates 18 to generate a uniform upward axial-radial composite flow at the bottom of the flotation tank 1, so that the bubbles and quartz sand particles can fully collide and float stably, while suppressing tangential eddies, keeping the liquid surface stable, and providing a stable, low-fluctuation foam layer for the scraper 13, further improving the flotation purity.
[0042] The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
