Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for fluorite ore flotation. Background Technology

[0002] Wastewater is generated during the flotation process of fluorite ore. Fluorite flotation is a method to extract useful minerals from fluorite ore and separate them from waste rock. The wastewater generated during this process contains a large amount of suspended solids, mineral particles, and chemical reagents, which can pollute the environment if not treated promptly. Chinese Patent (Announcement No. CN222159872U) discloses a wastewater treatment flocculation flotation device. This device uses a motor-driven rotary shaft to achieve multi-level stirring. The design of the feeding trough makes the dosing process more uniform and convenient. The feeding trough is fixed to a sliding block by a fixing frame. As the sliding block moves, the feeding trough can add coagulants and flocculants to the wastewater at different depths. This design not only improves the mixing and reaction speed but also allows the coagulants and flocculants to more fully contact and react with impurities in the wastewater, thus improving the treatment effect. However, it cannot treat floating grease and other light suspended solids, resulting in a limited treatment effect. Therefore, this utility model proposes a wastewater treatment device for fluorite ore flotation to improve the above-mentioned problems. Utility Model Content

The cylinder 1 is the main body of the device. The wastewater to be treated is added through the bottom of the cylinder 1, along with flocculants and coagulants. This ensures thorough contact between the wastewater and the flocculants / coagulants, separating impurities. The impurities then settle to the bottom of the cylinder 1. Oil and light impurities on the surface of the treated wastewater are floated by the flotation mechanism. The treated wastewater is then discharged through the drain pipe 3, achieving efficient separation while ensuring the treatment effect of oil and light impurities. A stirring mechanism is used to agitate the wastewater inside the cylinder 1, ensuring thorough mixing of the wastewater and added reagents, accelerating the chemical reaction and sedimentation process, and improving treatment efficiency.

[0029] In some embodiments, at least three supports 4 are evenly distributed at the bottom of the cylinder 1, and a settling cylinder 5 is disposed at the center of the bottom of the cylinder 1. A cylinder cover 6 is detachably connected to the bottom of the settling cylinder 5, and one end of the drain pipe 3 is connected to the center of the cylinder cover 6. Figure 1-5 As shown, the settling cylinder 5 is used to collect sediment in sewage for easy subsequent cleaning. The connection between the cylinder cover 6 and the settling cylinder 5 can be a flange connection.

[0030] In some embodiments, the end of the drain pipe 3 furthest from the cylinder cover 6 is respectively provided with a first branch pipe 7 and a second branch pipe 8, and a first electric valve and a second electric valve are respectively provided on the first branch pipe 7 and the second branch pipe 8. Figure 1-5 As shown, the first branch pipe 7 and the second branch pipe 8 are used to connect the sewage pipe and the chemical pipe, respectively, so that chemicals and sewage can be added into the cylinder 1 at the same time. The first electric valve and the second electric valve are both commercially available. By controlling the opening and closing of the first electric valve and the second electric valve, the liquid discharge at different treatment stages can be controlled, which is convenient for operation according to the actual situation. For example, sewage and chemicals can be added in different proportions, or the chemical flow can be paused and added again after the chemicals are mixed in the cylinder 1.

One end of each flotation tube 12 penetrates the bottom of the flotation disk 9, and the other end extends vertically upward and is flush with the edge of the frame plate 11. Figure 1-5As shown, by controlling the liquid level inside the cylinder 1, the wastewater can be directed upward through the gap between the frame plate 11 and the inner wall of the cylinder 1 and enter the flotation plate 9, or it can enter the flotation plate 9 through the evenly distributed flotation tubes 12. When there are floating objects and foam on the surface of the wastewater, flotation separation is achieved. After the flotation is completed, the wastewater is cleaned.

Figure 1-5 As shown, the first connecting pipe 15 and the second connecting pipe 16 of the drain pipe 3 are used to discharge liquid and connect to an external aerator, respectively. The aerator is commercially available, which allows aeration to be performed below the liquid surface inside the cylinder 1. The bubbles generated by aeration adhere to the fine impurities and residual agents in the sewage, causing them to float to the water surface, thereby achieving more efficient separation. The connection between the extension pipe 13 and the drain pipe 3 can be a snap-fit ​​or bolt connection. The through hole 14 on the extension pipe 13 allows the gas to be uniformly delivered to the liquid surface, fully realizing the aeration effect.

For example... Figure 1-5As shown, the bottom of the cylinder 1 is provided with an arc-shaped surface. After aeration and flotation are completed, the action of the reagent causes the impurities in the wastewater to settle towards the bottom of the cylinder 1 along the gap between the bottom of the cylinder 1 and the filter plate 19. At the same time, the filter plate 19 prevents the impurities from floating further towards the top of the cylinder 1 when wastewater is added into the cylinder 1. The filter plate 19 is held at the bottom of the cylinder 1 by the support legs 20. The connection between the support legs 20 and the cylinder 1 can be by bonding, snap-fitting or bolting.
