Description

Technical Field

[0001] This utility model relates to the technical field of flotation devices, and specifically discloses a mechanical stirring flotation device for quartz sand production. Background Technology

[0002] Quartz sand is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. Its main mineral component is SiO2. Quartz sand is milky white or colorless and translucent. It is an important industrial mineral raw material, a non-hazardous chemical, and is widely used in glass, casting, ceramics and refractory materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries.

[0003] Chinese Patent No. CN220547101U discloses a mechanical stirring flotation device for quartz sand production, including a rodless cylinder, a pneumatic slide plate, a support baffle, and a foam scraper. The rodless cylinder is equipped with a pneumatic slide plate, and two sets of foam scrapers are arranged inside the fixed frame. A connecting arm is provided at the connection between the pneumatic slide plate and the foam scraper, and a support baffle is provided on the upper side of the connection between the two sets of foam scrapers. Multiple sets of water seepage filter holes are evenly opened inside the foam scraper, and push components are provided on the left and right sides of the foam scraper. This utility model has a reasonable structure. The flotation mechanism facilitates convenient collection of floating matter in the flotation box. At the same time, the foam scraper can reciprocate to quickly scrape away the floating matter in the flotation box, which is beneficial for the collection of floating matter in the flotation box, reduces the time consumption of the flotation process, and improves the production efficiency of quartz sand.

[0004] The aforementioned document relies on scraper machinery to collect foam, which has a complex transmission mechanism and high energy consumption. When the foam layer is stationary, "dead corners" are prone to appear, and small air bubbles are trapped on the surface of the tank, resulting in poor foam cleaning effect. Therefore, a mechanical stirring flotation device for quartz sand production is needed to solve this problem. Utility Model Content

[0005] This invention proposes a mechanical stirring flotation device for quartz sand production. By using a dynamic airflow foam cleaning structure, the range of airflow cleaning is expanded, which can efficiently clean the foam in the device body, prevent foam from accumulating in the device, and effectively improve the flotation efficiency.

[0006] This utility model is implemented as follows: a mechanical stirring flotation device for quartz sand production includes a device body, an agitator is provided inside the device body, a discharge pipe is connected to the bottom of the outer wall of the device body, a foam discharge port is provided through the right side of the device body, a cover plate is provided at the top of the device body, and a dynamic airflow foam cleaning structure is provided at the bottom of the cover plate.

[0007] The dynamic airflow foam cleaning structure includes a through groove in the middle of the bottom end of the cover plate, a linear slide rail inside the through groove, a slider slidably connected to the outer wall of the linear slide rail, an air collecting chamber installed at the bottom end of the slider, an inclined nozzle connected to the outer wall of the air collecting chamber, a blower on the upper end of the cover plate, and a telescopic hose penetrating the cover plate connecting the air outlet of the blower and the air collecting chamber.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-4 A mechanical stirring flotation device for quartz sand production includes a device body 1, an agitator 102 is provided inside the device body 1, a discharge pipe 101 is connected to the bottom of the outer wall of the device body 1, a foam discharge port 103 is provided through the right side of the device body 1, a cover plate 2 is provided at the top of the device body 1, and a dynamic airflow foam cleaning structure is provided at the bottom of the cover plate 2.

[0025] The dynamic airflow foam cleaning structure includes a through groove in the middle of the bottom end of the cover plate 2. A linear slide rail 201 is provided inside the through groove. A slider 202 is slidably connected to the outer wall of the linear slide rail 201. An air collecting chamber 204 is installed at the bottom end of the slider 202. An inclined nozzle 205 is connected to the outer wall of the air collecting chamber 204. A blower 203 is provided on the upper end of the cover plate 2. A telescopic hose 206 that penetrates the cover plate 2 is connected between the air outlet end of the blower 203 and the air collecting chamber 204.

[0026] Both the front and rear sides of the inner wall of the device body 1 are provided with corrugated guide plates 4 that extend into the bubble outlet 103, and the guide plates 4 are inclined.

[0027] In this embodiment: During the quartz sand flotation process, the blower 203 and the linear slide rail 201 are activated. The airflow generated by the blower 203 enters the air collection chamber 204 through the telescopic hose 206 and is blown out through the nozzle 205. The slider 202 drives the air collection chamber 204 to slide on the linear slide rail 201, and the nozzle 205 moves dynamically to form a directional airflow curtain, which blows the foam in various positions in the device body 1 toward the foam discharge port 103, eliminating dead corners where foam is trapped, and allowing the foam to be discharged in time, ensuring that the flotation work is carried out continuously and efficiently. Furthermore, the dynamic airflow foam cleaning structure expands the range of airflow cleaning, which can efficiently clean the foam in the device body 1, avoid foam accumulation in the device, and effectively improve the flotation efficiency.

[0028] The corrugated guide plate 4 reduces the flow resistance of foam, and the inclined design increases the sliding speed of foam, so that the foam can flow more smoothly along the guide plate 4 to the foam discharge port 103, further optimizing the foam discharge process.

[0029] As a technical optimization of this utility model, a foam collection tank 3 is provided on the right side of the device body 1. A notch 303 aligned with the foam discharge port 103 is opened on the side of the foam collection tank 3 near the device body 1. A removable filter screen 301 is inserted into the inside of the foam collection tank 3. A drain pipe 302 is connected to the bottom of the foam collection tank 3.

[0030] In this embodiment: when the foam in the device body 1 is discharged through the foam discharge port 103, the foam enters the foam collection tank 3 through the notch 303. The filter screen 301 intercepts the foam in the tank. The liquid in the foam passes through the filter screen 301 and is discharged through the drain pipe 302. After a certain amount of foam is collected, the filter screen 301 is pulled out and the intercepted foam is further processed. The whole process is simple to operate and has a good collection effect.

[0031] As a technical optimization of this utility model, the nozzle 205 is a slit-type flat nozzle structure.

[0032] In this embodiment, the nozzle 205 with a slit-type flat nozzle structure can significantly improve the airflow coverage width, blow foam over a larger area, and enable the foam to move towards the foam discharge port 103 more quickly and evenly, further enhancing the foam cleaning effect, reducing the possibility of foam residue in the device body 1, and improving the working performance of the flotation device.

[0033] As a technical optimization of this utility model, the upper end face of the cover plate 2 is provided with a feed inlet 207 that communicates with the device body 1, and the feed inlet 207 is located behind the through groove.

[0034] In this embodiment: the feed inlet 207 facilitates the feeding of slurry into the device body 1. The feed inlet 207 and the through channel are staggered to avoid the slurry from contacting the linear slide rail 201.

[0035] As a technical optimization of this utility model, the surface of the guide plate 4 is coated with a hydrophobic nano-coating.

[0036] In this embodiment: by coating the surface of the guide plate 4 with a hydrophobic nano-coating, the foam sliding resistance can be reduced, allowing the foam to flow more smoothly along the guide plate 4 to the foam outlet 103.

[0037] As a technical optimization of this utility model, a controller is installed on the outer wall of the device body 1, and the linear slide rail 201, the blower 203 and the stirring component 102 are all electrically connected to the controller.

[0038] In this embodiment, the linear slide rail 201, the blower 203, and the agitator 102 can be controlled to work normally by the controller.

[0039] The working principle and usage process of this utility model are as follows: During the quartz sand flotation process, slurry is introduced into the device body 1 through the feed inlet 207, and reagents are added. The slurry and reagents are stirred by the agitator 102, causing the generated foam to float on the surface of the device body 1. Then, the blower 203 and the linear slide rail 201 are started. The airflow generated by the blower 203 enters the air collection chamber 204 through the telescopic hose 206 and is blown out through the nozzle 205. The slider 202 drives the air collection chamber 204 to slide on the linear slide rail 201, and the nozzle 205 moves dynamically. A directional airflow curtain is formed, blowing the foam from various positions inside the device body 1 toward the foam discharge port 103. The corrugated guide plate 4 reduces the foam flow resistance, and the inclined design increases the foam sliding speed, allowing the foam to flow more smoothly along the guide plate 4 toward the foam discharge port 103. The foam enters the foam collection tank 3 through the notch 303, and the filter screen 301 intercepts the foam in the tank. The liquid in the foam passes through the filter screen 301 and is discharged through the drain pipe 302. After a certain amount of foam is collected, the filter screen 301 is removed, and the intercepted foam is further processed.
