[0022] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Combine the following Figures 1 to 3 The utility model is described in detail.

[0024] A lithium ore flotation device comprises a main body 1, an air filling tube 2 is arranged at the bottom of the main body 1, a spiral tube 201 is arranged at one end of the air filling tube 2, an exhaust hole 2011 is arranged on the side wall of the spiral tube 201, a contraction groove 2012 is arranged on one side of the middle of the exhaust hole 2011, a protective component is arranged in the middle of the contraction groove 2012, and the protective component slides along the contraction groove 2012.

[0025] First, lithium ore and other minerals that need to be floated are placed into the inner body 1, and then the flotation liquid for flotation is poured in, and then the air is injected into the body 1 by connecting the external air pump through the inflation tube 2. By injecting air into the flotation liquid, bubbles are generated. When the bubbles float, they will collide and attach to the mineral particles, and some mineral particles that need to be screened will attach to the bubbles from the slurry and be screened to the liquid surface, so as to screen the minerals.

[0026] Furthermore, the spiral tube 201 is a spirally connected pipe to the inflation tube 2, and the exhaust hole 2011 also includes an airflow block 2013 and a limiting block 2014. The airflow block 2013 is a protrusion arranged on one side of the middle part of the exhaust hole 2011, and the limiting block 2014 is arranged at the opening of the contraction groove 2012. The airflow block 2013 is arranged on the side of the exhaust hole 2011 away from the contraction groove 2012, and the limiting block 2014 is a protrusion protruding on both sides of the opening of the contraction groove 2012.

[0027] At the same time, when the airflow is injected into the inflation tube 2, the airflow will be discharged through the spiral tube 201. Due to the spiral design of the spiral tube 201, when the airflow passes through the spiral tube 201, the centripetal force of the airflow will cause a certain centripetal force to be generated when the airflow is discharged through the exhaust hole 2011. The centripetal force of the airflow discharge will drive the flotation liquid and the slurry to be stirred to a certain extent, so that the slurry will fully move in the flotation liquid and then allow the mineral particles to attach to the bubbles.

[0028] Furthermore, the protective component includes a blocking plate 202, a counterweight 2021, an arc groove 2022 and a sliding block 2023. The blocking plate 202 is connected in the shrinkage groove 2012, the counterweight 2021 is arranged at one end of the blocking plate 202, the arc groove 2022 is arranged on one side of one end of the counterweight 2021, and the sliding block 2023 is arranged at one end of the blocking plate 202 away from the counterweight 2021. The blocking plate 202 is an arc-shaped plate that matches the opening area of ​​the exhaust hole 2011, and the thickness of the blocking plate 202 matches the spacing between the limiting blocks 2014. The sliding block 2023 is a protrusion arranged on both sides of one end of the blocking plate 202, and a protruding portion on one side of the sliding block 2023 is connected to a ball, and the sliding block 2023 is fitted with the inner wall of the shrinkage groove 2012 through the protruding ball side.

[0029] At the same time, when the airflow is discharged toward the exhaust hole 2011, the airflow will be discharged toward the gap between the baffle plate 202 and the airflow block 2013. Because the flow rate of the airflow is too large, the airflow will impact the arc groove 2022. The arc surface of the arc groove 2022 guides the impact force of the airflow when it impacts the groove, so that the airflow will exert a certain pressure on the baffle plate 202, thereby generating a certain upward thrust on the baffle plate 20, thereby driving the baffle plate 202 to shrink and move toward the shrinkage groove 2012, so that the airflow can be discharged smoothly.

[0030] At the same time, the blocking plate 202 cooperates with the contraction groove 2012 through the sliding blocks 2023 on both sides of one end, and the sliding block 202 is fitted with the contraction groove 2012 through a ball protruding from one side, so that the friction of the blocking plate 202 during contraction and movement is reduced, allowing it to be more easily contracted and moved when impacted by airflow, and at the same time, the bottom of the sliding block 2023 cooperates with the limiting block 2014, so that when the work stops, the blocking plate 202 can be better reset under the influence of gravity because of the certain weight added by the counterweight block 2021, so that when the exhaust port is not poured into the flotation liquid, the slurry will not enter the spiral tube 201 from the exhaust hole 202 to cause blockage when the slurry is poured and the inflation pipe 2 is not started.

[0031] The following is a specific implementation process of the utility model. First, lithium ore and other minerals that need to be floated are placed into the inner body 1, and then the flotation liquid for flotation is poured in. Then, the external air pump is connected to the inflation tube 2 to inject air into the body 1. By injecting air into the flotation liquid, bubbles are generated. When the bubbles float, they collide and adhere to the mineral particles. Some mineral particles that need to be screened will be attached to the bubbles from the slurry and screened to the liquid surface, so as to screen the minerals. At the same time, when the inflation tube 2 injects the airflow, the airflow will be discharged through the spiral tube 201. Because of the spiral design of the spiral tube 201, when the airflow passes through the spiral tube 201, due to the centripetal force of the airflow, when the airflow is discharged through the exhaust hole 2011, a certain centripetal force will be generated, and the centripetal force of the airflow discharge will drive the flotation liquid and the slurry to stir to a certain extent, so that the slurry will be fully active in the flotation liquid and then allow the mineral particles to attach to the bubbles.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
