[0035] The present invention will be further described below in conjunction with embodiments.

[0036] Please refer to Figures 1 - 10The present invention provides a flotation mineral separation device for mining, comprising a cylinder shell 4, the cylinder shell 4 is horizontally arranged and one end of the cylinder shell 4 is open, a bottom plate 8 is fixed to the bottom end of the cylinder shell 4, a filter cylinder 5 coaxially arranged with the cylinder shell 4 is arranged in the cylinder shell 4, a baffle 12 is fixed to the bottom of the open end of the cylinder shell 4, a joint shaft 13 is fixed to the center of one end of the filter cylinder 5 close to the closed end of the cylinder shell 4, the joint shaft 13 is rotatably connected to the center of the closed end side wall of the cylinder shell 4, a motor 10 is fixed to the outer side wall of the closed end of the cylinder shell 4, and the output end of the motor 10 and the joint shaft 13 are far away from the filter. One end of the cylinder 5 is fixed, and a drain pipe 9 connected to the bottom of the cylinder shell 4 is fixed at the bottom of the cylinder shell 4. A valve is installed on the drain pipe 9. A collection component 1 is provided at the top of the cylinder shell 4 for continuously clearing the filter cylinder 5 by rotating with the filter cylinder 5. A discharge component 2 is provided in the collection component 1 for assisting in cleaning the filter cylinder 5 and automatically clearing out impurities in cooperation with the collection component 1. A striking component 3 is provided on the inner side wall of the cylinder shell 4 for cooperating with the side wall of the filter cylinder 5 to make the filter cylinder 5 vibrate continuously. A plurality of arc plates 11 are fixed on the inner side wall of the filter cylinder 5. The arc plates The concave side of 11 faces the rotation direction of the filter cartridge 5; when the ore needs to be treated for impurities, the crushed small ore blocks are poured into the filter cartridge 5, and the cleaning water is discharged into the cartridge shell 4 through a handheld water pipe, and a certain flotation agent is added to the cleaning water to form a cleaning liquid. The flotation agent includes a collector, a frother and a regulator, etc. The cleaning liquid level is located in the middle of the filter cartridge 5, so that the ore blocks are soaked and cleaned by the cleaning liquid, and the granular impurities adhered to the surface of the ore blocks and the mineral particles mixed therein can float on the liquid surface under the action of the buoyancy of the water to remove the mineral particles. Impurities in the stone are removed to improve the purity of the ore. In this process, the motor 10 is started to work, and the output end of the motor 10 drives the filter cartridge 5 to rotate slowly. Part of the ore is accumulated in the local groove of the filter cartridge 5, so that the ore is continuously driven upward by the groove of the filter cartridge 5. After the local groove of the filter cartridge 5 rotates to a certain height, part of the ore in the local groove of the filter cartridge 5 automatically rolls down and falls out, thereby effectively increasing the movement degree of the ore in the filter cartridge 5, increasing the contact area between the cleaning water and the ore surface, thereby increasing the effect of impurities floating to the water surface and improving the adequacy of impurity removal;

[0037] During the rotation of the filter cartridge 5, a part of the ore in the local groove on the filter cartridge 5 falls to the bottom of the filter cartridge 5. The filter cartridge 5 drives a plurality of arc-shaped plates 11 to rotate synchronously, so as to carry another part of the washed ore upward through the arc-shaped plates 11, and then transfer and pour the ore into the inside of the aggregate component 1 in small portions through the arc-shaped plates 11 for centralized collection. At the same time, the aggregate component 1 uniformly blows out the gas with a certain air pressure onto the side surface of the filter cartridge 5, and uses the scouring action of the air flow to clean the filter holes on the filter cartridge 5. The cleaning is more convenient and simple, ensuring that the filter cartridge 5 always has efficient and stable filtering ability. At the same time, the gas in the aggregate component 1 is transported to the inside of the discharge component 2, and the discharge component 2 uniformly blows out the gas into the inside of the aggregate component 1 in a refined manner, so as to blow and discharge the ore collected in the aggregate component 1 through the air flow, thus forming an automatic discharging effect, automatically taking out the washed ore, eliminating the operation of manually taking out the washed ore regularly, effectively reducing the workload, having a simple structure, low use and maintenance costs, and strong practicability. At the same time, the discharge component 2 synchronously blows out the air flow onto the inner side wall of the filter cartridge 5, so as to blow off the ore particles adhering to the inner side wall of the filter cartridge 5, further improving the sufficiency of discharging. When the filter cartridge 5 rotates, the side wall of the filter cartridge 5 intermittently squeezes and triggers the impact component 3, so that the impact component 3 continuously knocks on the side wall of the filter cartridge 5, making the filter cartridge 5 vibrate continuously, accelerating the falling of the impurities and ore particles adhering to the inner side wall of the filter cartridge 5, and at the same time making the liquid in the filter cartridge 5 have a higher flow rate, accelerating the filtering speed of the liquid. When the ore cleaning is completed, the valve on the drain pipe 9 is opened, and the washed mixed liquid in the shell 4 is discharged through the filter holes on the filter cartridge 5 and the drain pipe 9.

[0038] Further, as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 10As shown, it is worth specifically explaining that the aggregate component 1 includes a receiving seat 101 fixed to the inner side wall of the top end of the cylinder shell 4. Notches 102 are formed on both side surfaces of the receiving seat 101. The side wall of the filter cylinder 5 penetrates through the notches 102, and the arc-shaped plate 11 can pass through the notches 102. A first ventilation cavity 103 arranged along the length direction of the receiving seat 101 is formed inside the top end of the receiving seat 101. An air inlet pipe 105 communicated with the first ventilation cavity 103 is fixed to the top end of the receiving seat 101. A first blowing hole 104 communicated with the first ventilation cavity 103 is formed on the inner side wall of the top end of the receiving seat 101. There are multiple first blowing holes 104, and the multiple first blowing holes 104 are equidistantly distributed. During the rotation of the filter cylinder 5, part of the ore in the local groove of the filter cylinder 5 falls to the bottom of the filter cylinder 5. The filter cylinder 5 drives the multiple arc-shaped plates 11 to rotate synchronously, so as to drive another part of the washed ore to move upward through the arc-shaped plates 11. The arc-shaped plates 11 continuously transfer and pour part of the washed ore into the inside of the receiving seat 101 for centralized collection. The air inlet pipe 105 is externally connected to an air pump, and air flow is conveyed into the first ventilation cavity 103 through the air inlet pipe 105, so that the air flow is evenly blown out to the side surface of the filter cylinder 5 through the multiple first blowing holes 104. By using the scouring effect of the air flow, the filter holes on the filter cylinder 5 are cleared, and the cleaning is more convenient and simple, ensuring that the filter cylinder 5 always has high-efficiency and stable filtering ability.

[0039] Further, as shown in Figure 3 、 Figure 5 、 Figure 7 and Figure 8 As shown, it is worth specifically explaining that the discharging component 2 includes a second ventilation cavity 201 formed inside one end of the receiving seat 101 close to the opening end of the cylinder shell 4. Multiple second blowing holes 202 are equidistantly distributed on the side surface of one end of the second ventilation cavity 201 located inside the receiving seat 101. An air delivery pipe 204 is communicated between the first ventilation cavity 103 and the second ventilation cavity 201. A discharging chute 206 communicated with the inside of the receiving seat 101 and extending out from the inside of the cylinder shell 4 is fixed to one end of the receiving seat 101 far from the second ventilation cavity 201. During specific operation, the gas in the first ventilation cavity 103 is conveyed into the second ventilation cavity 201 through the air delivery pipe 204, and the gas is centrally blown into the inside of the receiving seat 101 through the multiple second blowing holes 202, so that the ore collected in the receiving seat 101 can be blown and pushed into the discharging chute 206, and the impurities are discharged through the discharging chute 206, forming an automatic discharging effect. The washed ore is automatically taken out, saving the operation of manually taking out the washed ore regularly, effectively reducing the workload, having a simple structure, low use and maintenance costs, and strong practicability.

[0040] Further, as shown in Figure 7 and Figure 8As shown, it is worth specifically stating that at one end side inside the receiving base 101, the second ventilation cavity 201 is provided with a plurality of third blowing holes 203 that incline upwards. The plurality of third blowing holes 203 are equidistantly distributed and the third blowing holes 203 are arranged above the second blowing holes 202. During specific operation, the air flow in the second ventilation cavity 201 is blown out through the plurality of third blowing holes 203 that incline upwards onto the inner side wall of the filter cartridge 5, so as to blow down the ore particles adhering to the inner side wall of the filter cartridge 5 through the air flow, further improving the sufficiency of discharging materials.

[0041] Furthermore, as Figure 4 and Figure 9 shown, it is worth specifically stating that the impact assembly 3 includes an end piece 301 installed on the inner side wall of the cylinder shell 4. An arc-shaped metal plate 304 is fixed to the end of the end piece 301. A metal elastic piece 302 that contacts a local protrusion on the side wall of the filter cartridge 5 is fixed to the end of the arc-shaped metal plate 304 away from the end piece 301. The metal elastic piece 302 is inclined. The end of the metal elastic piece 302 away from the arc-shaped metal plate 304 deflects towards the center of the cylinder shell 4 and contacts a local protrusion on the side wall of the filter cartridge 5. The filter cartridge 5 rotates in the direction away from the arc-shaped metal plate 304 of the metal elastic piece 302. When the filter cartridge 5 rotates, relative movement is formed between the filter cartridge 5 and the metal elastic piece 302, so that the metal elastic piece 302 is intermittently squeezed by a plurality of side wall protrusions of the filter cartridge 5, causing the metal elastic piece 302 to be compressed. When the side wall protrusion of the filter cartridge 5 rotates away from the metal elastic piece 302, the metal elastic piece 302 rebounds to knock on the side wall of the filter cartridge 5, causing the filter cartridge 5 to vibrate continuously, so as to accelerate the falling of impurities and ore particles adhering to the inner side wall of the filter cartridge 5. At the same time, when discharging liquid, the liquid in the filter cartridge 5 has a higher flow rate, accelerating the discharging speed of the liquid.

[0042] This solution has the following working process: when it is necessary to remove impurities from the ore, the crushed small ore blocks are poured into the filter cartridge 5, and the cleaning water is discharged into the cartridge shell 4 through a handheld water pipe. A certain flotation agent is added to the cleaning water to form a cleaning liquid. The cleaning liquid level is located in the middle of the filter cartridge 5, so that the ore blocks are soaked and cleaned by the cleaning liquid. The granular impurities adhered to the surface of the ore blocks and the mineral particles mixed therein can float on the liquid surface under the action of the buoyancy of the water, and the ore is cleaned and removed. In this process, the filter cartridge 5 is driven to rotate slowly through the output end of the motor 10. The filter cartridge 5 moves, and part of the ore accumulates in the local groove of the filter cartridge 5, so that the ore is continuously driven upward by the groove of the filter cartridge 5. After the local groove of the filter cartridge 5 rotates to a certain height, part of the ore in the local groove of the filter cartridge 5 automatically rolls down and falls out, thereby effectively increasing the movement degree of the ore in the filter cartridge 5 and increasing the contact area between the cleaning water and the ore surface. During the rotation of the filter cartridge 5, part of the ore in the local groove of the filter cartridge 5 falls to the bottom of the filter cartridge 5, and the other part of the cleaned ore is carried upward by the arc plate 11, and part of the cleaned ore is continuously transported by the arc plate 11. The gas is poured into the receiving seat 101 for centralized collection, and the airflow is transported to the first ventilation chamber 103 through the air inlet pipe 105, so that the airflow is evenly blown out to the side of the filter cartridge 5 through the plurality of first blowing holes 104, and the filter holes on the filter cartridge 5 are cleared by the flushing effect of the airflow. At the same time, the gas in the first ventilation chamber 103 is transported to the second ventilation chamber 201 through the air delivery pipe 204, and the gas is concentratedly blown out to the receiving seat 101 through the plurality of second blowing holes 202, so that the ore collected in the receiving seat 101 can be blown out into the discharge trough 206. , thereby discharging impurities through the discharge slot 206 and automatically discharging; when the filter cartridge 5 rotates, the filter cartridge 5 and the metal spring sheet 302 form a relative movement, so that the metal spring sheet 302 is intermittently squeezed by the multiple side wall protrusions on the filter cartridge 5 to compress the metal spring sheet 302, and when the side wall protrusions of the filter cartridge 5 turn away from the metal spring sheet 302, the metal spring sheet 302 rebounds and knocks the side wall of the filter cartridge 5, causing the filter cartridge 5 to vibrate continuously, thereby accelerating the falling of impurities and ore particles adhering to the inner wall of the filter cartridge 5, and at the same time making the liquid in the filter cartridge 5 have a higher flow rate when discharging.

[0043] Further as Figure 3 , Figure 7 and Figure 10 As shown, it is worth explaining in detail that the inner side wall of the bottom end of the receiving seat 101 is set as a curved surface 205; during specific operation, the curved surface 205 is set to increase the receiving area for the fallen small ore blocks, thereby increasing the scattering area of ​​the small ore blocks and improving the uniformity of the ore block scattering, which is conducive to the airflow to fully blow and discharge the small ores on the curved surface 205.

[0044] Further, as shown in Figure 1 , Figure 5 and Figure 6 it is worth specifically explaining that the side wall of the filter cartridge 5 is arranged in a concave-convex wavy shape; during specific operation, multiple groove parts can be formed by the side wall of the filter cartridge 5 with the concave-convex wavy structure, so as to carry some ore blocks upward and then automatically roll down and fall out, increasing the movement degree of the ore and cooperating with the arc plate 11 to transfer the ore in small amounts and multiple portions. At the same time, the filtering surface area of the filter cartridge 5 can be effectively increased, making the liquid spread more evenly during filtration, reducing the flow resistance of the liquid in the filter cartridge 5, and improving the filtration efficiency.

[0045] Further, as shown in Figure 9 it is worth specifically explaining that the mounting bolt 303 is threadedly connected to the side wall of the cylinder shell 4, and a threaded hole threadedly matched with the mounting bolt 303 is opened on the side surface of the end piece 301. The end piece 301 is fixed to the inner side wall of the cylinder shell 4 through the mounting bolt 303; during specific operation, when the metal elastic piece 302 is severely worn after long-term use and the elastic force decreases, the mounting bolt 303 is removed, so that the metal elastic piece 302 can be conveniently replaced.

[0046] Further, as shown in Figure 1 it is worth specifically explaining that a feeding port 6 is opened on the side surface of the baffle 12, and a cover plate 7 is hinged in the feeding port 6; during specific operation, by opening the cover plate 7, it is convenient to put the ore to be impurity-removed and cleaned into the interior of the filter cartridge 5 through the feeding port.

[0047] In summary: The starting motor 10 operates, and the output end of the motor 10 drives the filter cylinder 5 to rotate slowly. Part of the ore accumulates in the local groove of the filter cylinder 5, so that the ore is continuously driven upward through the groove of the filter cylinder 5. After the local groove of the filter cylinder 5 rotates to a certain height, part of the ore in the local groove of the filter cylinder 5 automatically rolls and falls out, effectively increasing the movement degree of the ore in the filter cylinder 5, improving the contact area between the cleaning water and the surface of the ore, thus improving the effect of impurities floating to the water surface and enhancing the thoroughness of impurity removal; during the rotation of the filter cylinder 5, part of the ore in the local groove on the filter cylinder 5 falls to the bottom of the filter cylinder 5, and the filter cylinder 5 drives the plurality of arc-shaped plates 11 to rotate synchronously, so that the other part of the washed ore is carried upward by the arc-shaped plates 11, and the ore is transported and poured into the interior of the aggregate component 1 in small amounts and multiple portions for centralized collection. At the same time, the aggregate component 1 evenly blows out the gas with a certain air pressure onto the side surface of the filter cylinder 5, and uses the scouring action of the air flow to clear the filter holes on the filter cylinder 5. The cleaning is more convenient and simple, ensuring that the filter cylinder 5 always has high-efficiency and stable filtering ability; at the same time, the gas in the aggregate component 1 is transported to the interior of the discharge component 2, and the discharge component 2 evenly and finely blows out the gas into the interior of the aggregate component 1, so that the ore collected in the aggregate component 1 is blown and discharged through the air flow, thus forming an automatic discharging effect, automatically taking out the washed ore, eliminating the operation of manually taking out the washed ore regularly, effectively reducing the workload, having a simple structure, low use and maintenance costs, strong practicability. At the same time, the air flow is synchronously blown out from the inner side wall of the filter cylinder 5 through the discharge component 2, so that the ore particles adhering to the inner side wall of the filter cylinder 5 are blown off, further improving the thoroughness of discharging; when the filter cylinder 5 rotates, the side wall of the filter cylinder 5 is intermittently squeezed to trigger the impact component 3, so that the impact component 3 continuously knocks on the side wall of the filter cylinder 5, causing the filter cylinder 5 to vibrate continuously, accelerating the falling of the impurities and ore particles adhering to the inner side wall of the filter cylinder 5, and at the same time making the liquid in the filter cylinder 5 have a higher flow rate and accelerating the filtering speed of the liquid.

[0048] The motor 10 can be purchased on the market. The motor 10 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
