Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ore dressing, especially relates to a flotation machine dosing and spraying device. BACKGROUND

[0002] Flotation is an important part of ore dressing technology, which is a scientific technology for separating minerals by using the difference in surface physical and chemical properties of hydrophobic and hydrophilic minerals. In the process of mineral flotation, chemical reagents that can adjust the surface properties of minerals, improve or reduce the floatability of minerals, make the properties of ore pulp and the stability of foam more conducive to mineral separation are collectively referred to as flotation reagents. In the actual production process of the ore dressing plant, commonly used flotation reagents include collectors, frothers, regulators and depressants. At present, the common way to add flotation reagents in the ore dressing plant is to flow to the surface of the flotation foam layer. This dosing method is concentrated addition of reagents, and the flotation reagents are not fully mixed with the ore pulp, which is prone to "tank killing phenomenon" (large area of foam layer crushing), resulting in the scraping of the flotation slurry, and the effective enrichment of valuable metals, causing waste of mineral resources.

[0003] After searching, in the Chinese public utility model patent publication No. CN218078410U, an automatic dosing device for a flotation machine is disclosed, which is provided with an annular pipe below the agitator of the flotation machine, and the reagent is sprayed from the nozzle on the annular pipe. The impeller of the agitator disperses the flotation reagent, so that the flotation reagent is dispersed. When using the device, the flotation slurry concentration is first considered. When the concentration of the ore pulp is ≥25% and the proportion of -0.074mm particle size ore is <50%, it is easy to cause the deposition of coarse particle ore covering the annular pipe, resulting in the blockage of the annular pipe and the inability to continuously dose. When the impeller, motor, flow sensor and other related devices fail and need to be processed for a short time, if the flotation machine is not emptied, the annular pipe is easy to be blocked by the deposited ore pulp. If the emptying process is performed, it will affect the continuous and stable production, and cause waste of resources. Therefore, we propose a flotation machine dosing and spraying device.

[0020] Embodiment 1

[0021] As Figures 1-2As shown, a flotation machine and a dosing and spraying device, comprising a dosing pipe 1, the upper surface of the dosing pipe 1 is fixedly connected with an electromagnetic valve I 2, the dosing pipe 1 is fixedly connected with a medicament buffer tank 3, the medicament buffer tank 3 is connected with the dosing pipe 1 and an air inlet pipe 6 to form a three-way connection. The bottom of the dosing pipe 1 is fixedly connected with a hydraulic nozzle 7, and the lower surface of the hydraulic nozzle 7 has a medicament injection hole 8. The air inlet pipe 6 is fixedly connected with an electromagnetic valve II 4, and the electromagnetic valve II 4 is fixedly connected with a pressure gauge 5.

[0022] In specific use, the medicament flows into the dosing pipe 1, and after the electromagnetic valve I 2 is opened, the medicament flows into the medicament buffer tank 3. The electromagnetic valve I 2 is closed, the electromagnetic valve II 4 is opened, and air with a pressure of 0.25mpa is introduced. The pressure air enters the medicament buffer tank 3 from the air inlet pipe 6, the medicament is pushed into the hydraulic nozzle 7 by the pressure air, and is sprayed out of the injection hole 8. Then, the medicament is sprayed into the ore pulp and presents a dispersed state. After the medicament is sprayed into the ore pulp, the electromagnetic valve II 4 is closed. This series of actions is repeated, so that the medicament is dispersed in the ore pulp, and the ore pulp and the medicament fully act on each other.

[0023] In this embodiment, the electromagnetic valve I controls the entry of the medicament. When the electromagnetic valve I is closed, the backflow of the medicament is prevented.

[0024] In specific use, the electromagnetic valve I is opened, the medicament flows into the dosing pipe 1, and the electromagnetic valve I is closed, so that the backflow of the medicament is prevented and the medicament flows into the medicament buffer tank 3.

[0025] In this embodiment, the electromagnetic valve II introduces the pressure air into the medicament buffer tank 3 from the air inlet pipe 6.

[0026] In specific use, the electromagnetic valve I is opened, the medicament flows into the dosing pipe 1, and the electromagnetic valve I is closed. The electromagnetic valve II 4 is opened, and air with a pressure of 0.25mpa is introduced. The pressure air enters the medicament buffer tank 3 from the air inlet pipe 6.

[0027] In this embodiment, after the electromagnetic valve I 2 is opened, the medicament flows into the medicament buffer tank 3. The medicament buffer tank is made of transparent glass material, so that whether the medicament pipeline is blocked can be observed.

[0028] In specific use, after the electromagnetic valve I 2 is opened, the medicament flows into the medicament buffer tank 3. After the medicament flows into the medicament buffer tank 3, the state of the medicament can be observed, and whether the pipeline is blocked can be checked.

[0029] In this embodiment, the upper surface of the electromagnetic valve II 4 is fixedly connected with the pressure gauge 5.

[0030] In specific use, the electromagnetic valve II is opened, and air with a pressure of 0.25mpa is introduced. The pressure gauge 5 can be used to check whether the pressure is 0.25mpa, so that the air inlet pressure can be adjusted.

[0031] In this embodiment, when solenoid valve I2 is open, solenoid valve II is closed; when solenoid valve I2 is closed, solenoid valve II4 is open. Neither valve can be open or closed simultaneously.

[0032] In actual use, solenoid valve I2 and solenoid valve II4 are controlled by a computer timer. There is a time difference between their opening and closing. They will not open or close at the same time during non-maintenance periods.

[0033] Working principle: The reagent flows into the inlet pipe 1. After solenoid valve I2 opens, the reagent flows into the reagent buffer tank 3. Solenoid valve I2 closes, and solenoid valve II4 opens, allowing pressurized air at 0.25 MPa to enter. The pressurized air enters the reagent buffer tank 3 through the air inlet pipe 6. The reagent is propelled by the pressurized air into the hydraulic nozzle 7 and sprayed out through the injection hole 8, thus dispersing the reagent into the slurry in a diffused state. After the reagent is dispersed into the slurry, solenoid valve II4 closes. This series of actions is repeated, thereby ensuring that the reagent disperses in the slurry and that the slurry and reagent interact fully.

A first manual valve 10 is fixedly connected to the upper surface of the discharge pipe 9. A second manual valve 11 is provided below the discharge pipe 9.

[0036] In practical use, close solenoid valve II4, close the second manual valve 11, open the first manual valve 10, and after opening solenoid valve I2, the medicine flows into the medicine buffer tank 3 through the medicine inlet pipe, and is finally discharged through the medicine outlet pipe 9. The discharged medicine is collected in a measuring cup and is used only for measurement. Users can detect the amount of medicine added at one time and measure the accuracy of the medicine.
