[0053] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0054] Example:

[0055] like Figures 1 to 7 As shown, the flotation reagent quantitative automatic filling control device is characterized by comprising:

[0056] The high-pressure gas venturi tube 1 is connected in series to the pipeline supplying high-pressure gas to the flotation machine;

[0057] A flotation reagent filling pipe, the end of which is connected to the throat of the high-pressure gas venturi tube 1;

[0058] The magnetic opening and closing reagent controller is arranged in the flotation reagent filling pipe to control the opening and closing of the flotation reagent filling pipe;

[0059] A grouting venturi tube 4 is connected in series to a pipeline supplying slurry to the flotation machine;

[0060] The magnetic control tube 5 has its tail end connected to the throat of the grouting venturi tube 4 and its head end located outside the flotation reagent filling pipe, facing the magnetic opening and closing reagent controller;

[0061] The magnetic piston assembly is arranged in the magnetic control tube 5. As the pressure at the throat of the grouting venturi tube 4 changes, it moves in the magnetic control tube 5. The magnetic force changes the state of the magnetic opening and closing reagent controller to control the opening and closing control of the flotation reagent filling pipe.

[0062] Taking advantage of the necessary working conditions of the flotation machine requiring the injection of slurry and the injection of high-pressure gas, a high-pressure gas venturi tube 1 and a main venturi tube are set, and the flow pressure change of the fluid is used to control the position of the magnetic piston assembly in the magnetic control tube 5, so that the magnetic force inside it affects the action of the magnetic opening and closing agent controller in the flotation agent filling pipe, so that the flow rate (injection amount) of the slurry in the grouting pipe is associated with the filling of the flotation agent, and because the high-pressure gas delivery of the high-pressure gas venturi tube 1 remains stable, the agent flowing out of the opening of the magnetic opening and closing agent controller is only related to the flow rate of the slurry, reducing the influence of other external changes on the agent filling amount. Ultimately, the agent is added in an adaptive quantitative (fixed proportion) manner according to the slurry injection amount, and the added agent is dispersed under the action of the high-pressure gas flowing through the venturi tube, so that the agent contacts the slurry more quickly and evenly with the gas.

[0063] In this example, the flotation reagent filling pipe includes:

[0064] The front pipe 21 is trumpet-shaped, and its smaller end is connected to the throat of the high-pressure gas venturi tube 1;

[0065] The front end of the rear tube 22 is connected to the larger opening end of the front tube 21 through a magnetic opening and closing reagent controller, and the tail end is connected to the flotation reagent container.

[0066] In this embodiment, the magnetic opening and closing medicine controller includes:

[0067] The chassis 31 has an outer annular surface connected to the larger opening end of the front tube 21 and the front flange of the rear tube 22 by bolts; a fixed hole 311 is provided in the middle of the chassis 31;

[0068] A sliding limiting mechanism is provided on the chassis 31;

[0069] The gate plate 33 is mounted on the surface of the chassis 31 via a sliding limit mechanism. The surface of the gate plate 33 is in close contact with the surface of the chassis 31. The gate plate 33 is provided with a through-hole 331. When the gate plate 33 slides along the sliding limit mechanism, the flux of the through-hole 331 and the fixed hole 311 is positively correlated with the amount of movement of the gate plate 33 on the chassis 31.

[0070] The magnetic member 34 is provided on the gate 33;

[0071] The plate reset mechanism is provided on the chassis 31 and is connected to the magnetic member 34 or the gate 33 to control the gate 33 to move and reset on the chassis 31 so that the through hole 331 and the fixed hole 311 are completely staggered.

[0072] The gate-like structure can reduce the negative pressure generated by the high-pressure gas venturi tube 1 when the gate plate 33 moves, thereby reducing the impact force generated by the medicine, that is, reducing the resistance when the gate plate 33 is displaced, so that the magnetic part 34 is more sensitive to displacement under the action of the rubidium magnet 633.

[0073] In this embodiment, the sliding limiting mechanism includes:

[0074] Two L-shaped slot plates 321 are oppositely arranged on the chassis 31 and located on both sides of the fixed hole 311; the slot plates 321 and the surface of the bottom plate form a C-shaped slot; the end surface of the gate plate 33 is located in the C-shaped slot.

[0075] The gate plate 33 is arranged in this structure so that the plate surface of the gate plate 33 can be in contact with the plate surface of the bottom plate 31, thereby reducing the overflow of the medicine.

[0076] In this embodiment, the magnetic member 34 is attached to the outer surface of the gate plate 33;

[0077] The plate resetting mechanism comprises:

[0078] The bottom member 351 is L-shaped and fixed to the chassis 31 by screws, and is located directly below the magnetic member 34;

[0079] Several reset components are evenly distributed between the magnetic member 34 and the bottom member 351. The reset components include: two positioning posts 353 and a reset spring 352. The two positioning posts 353 are respectively located on the lower surface of the magnetic member 34 and the surface of the bottom member 351 facing the lower surface of the magnetic member 34. The two ends of the reset spring 352 are respectively sheathed on the two positioning posts 353.

[0080] The force storage and resetting are achieved through the action of the reset spring 352 , and the positioning column 353 can better limit the reset spring 352 so that it can maintain a vertical state.

[0081] In this embodiment, the chassis 31 , the gate plate 33 , the bottom piece 351 , the front tube 21 , and the rear tube 22 are all made of engineering plastics; the magnetic piece 34 is a rubidium magnet 633 or a magnetic material.

[0082] The use of engineering plastics can reduce the impact on magnetic materials.

[0083] In this embodiment, the axis of the magnetic control tube 5 is parallel to the axis of the slot plate 321, and the magnetic piston assembly includes:

[0084] The plug body 61 is arranged in the magnetic control tube 5 and faces the throat of the grouting venturi tube 4. The outer surface of the plug body 61 is seamlessly slidably connected to the inner wall of the magnetic control tube 5.

[0085] The plug reset mechanism is arranged in the control tube, with the lower end connected to the upper end surface of the plug body 61 and the middle part fixedly connected to the magnetic control tube 5;

[0086] The magnetic member is provided at the upper end of the plug resetting mechanism, facing the magnetic member 34 ; the magnetic member moves in the magnetic control tube 5 as the plug body 61 slides seamlessly in the magnetic control tube 5 .

[0087] Through the cavity formed by the plug body 61 and the magnetic control tube 5, the negative pressure change generated at the throat of the grouting venturi tube 4 can directly act on the plug body 61, driving the movement of the magnetic part.

[0088] In this embodiment, the surface of the plug body 61 is provided with at least one annular groove 611, and an annular sealing ring 612 is provided in the annular groove 611. The sealing portion of the annular sealing ring 612 is lip-shaped.

[0089] The annular sealing ring 612 has better sealing performance, and the lip-shaped structure can reduce sliding resistance while improving the sealing performance.

[0090] In this embodiment, the inner wall of the magnetic control tube 5 is provided with an annular inner groove 51;

[0091] The plug resetting mechanism comprises:

[0092] The connecting rod 621 has two ends connected to the upper end of the plug body 61 and the lower end of the magnetic member respectively;

[0093] The larger end of the conical spring 622 is disposed in the annular inner groove 51 , and the smaller end is fixedly connected to the active magnetic part of the plug body 61 .

[0094] The conical spring 622 is provided to store force, and its body is connected to the magnetic control tube 5 via the annular inner groove 51, thereby achieving more convenient production and manufacturing.

[0095] In this embodiment, the magnetic member includes:

[0096] The guide plate 631 has its lower end fixedly connected to the connecting rod 621. A plurality of raised strips 632 are provided on the cylindrical surface of the guide plate 631 in a uniform circumferential array. The outer end surfaces of the raised strips 632 are in contact with the inner wall of the magnetic control tube 5.

[0097] The neodymium magnet 633 is disposed on the upper surface of the guide plate 631 , facing the magnetic member 34 .

[0098] The guide plate 631 can guide the movement of the neodymium magnet 633, and the raised strip 632 can reduce friction resistance.

[0099] The flotation reagent quantitative automatic filling control device of this embodiment works as follows: Figure 1As shown, the device is installed outside the flotation machine to prevent the slurry in the flotation machine from contaminating the device, thereby affecting the working state of the device.

[0100] When the flotation machine is operating, slurry flows through the grouting venturi 4, generating negative pressure at its throat. This causes the plug 61 to descend, simultaneously driving the rubidium magnet 633 downward and simultaneously accumulating force in the conical spring 622. The lowering of the rubidium magnet 633 attracts the magnetic element 34 downward. This causes the perforation 331 in the gate plate 33 to descend, partially connecting it with the fixed hole 311 in the base plate 31. This allows the reagent to flow through the perforation 331 and fixed hole 311 into the front tube 21.

[0101] When the flotation machine is working, the high-pressure gas flowing through the high-pressure gas venturi tube 1 generates negative pressure at the throat of the high-pressure gas venturi tube 1, sucking the reagent located in the front tube 21 into the high-pressure gas venturi tube 1, and then being dispersed and injected into the slurry of the flotation machine.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
