Description

Technical Field

[0001] The invention relates to the technical field of emulsion preparation equipment, in particular to an emulsion proportioning device driven by water-based hydraulic pressure. Background Art

[0002] Emulsion is a commonly used hydraulic transmission medium in the mining industry. It has the advantages of low price, corrosion resistance, low viscosity, lubricity, and flame retardancy. It is generally made of emulsified oil and filtered water in a certain proportion. The concentration of mining emulsion is generally 3%-5%. If the concentration of emulsion is too low, it will affect the hard water resistance, stability, rust resistance and lubricity. The hydraulic equipment is prone to rust and the life is reduced, which seriously affects the economic benefits of mining production. If the concentration of emulsion is too high, the consumption of emulsified oil will increase, the defoaming ability will be weakened, and the swelling of rubber seals will increase, resulting in seal failure. Therefore, the concentration and stability of mining emulsion play an important role in the economy and safety of mining production.

[0003] Existing emulsion configuration technologies mostly use an electric water pump assisted by a ratio control valve to extract filtered water and emulsified oil into a liquid tank according to a ratio, and then mix and stir to form the required emulsion. This has defects such as potential safety hazards in electricity use, high cost of ratio control, and large overall space occupation of the equipment. There are also technical solutions that rely on human detection (for example: concentration and water-oil volume measurement) to control the ratio. This control method is relatively extensive and has low ratio efficiency. The concentration of the prepared emulsion fluctuates greatly, and the concentration stability of the emulsion cannot be maintained during the entire use process. It is not conducive to the life and reliability of hydraulic control and execution equipment that uses emulsion as a working medium, and brings great safety hazards to production.

[0025] Combine the following Figure 1 and Figure 2 The present invention describes a water-based hydraulically driven emulsion proportioning device. The water-based hydraulically driven emulsion proportioning device comprises: a water-based hydraulically driven device 1, a first non-circular gear pump 16, a second non-circular gear pump 13, and a housing. The housing, as the external structure of the overall device, provides support, installation, and protection for the water-based hydraulically driven device 1, the first non-circular gear pump 16, and the second non-circular gear pump 13 inside.

[0026] Among them, the water-based hydraulic drive device 1 has a water-based liquid inlet A1 and a water-based liquid outlet A0, the water-based liquid inlet A1 is used to introduce high-pressure water medium, and the water-based liquid outlet A0 is used to discharge low-pressure water medium, and the output shaft of the water-based hydraulic drive device 1 can rotate driven by the high-pressure water medium; the first non-circular gear pump 16 has a first liquid inlet B1 and a first liquid outlet B0, and the first non-circular gear pump 16 is connected to the output shaft of the water-based hydraulic drive device 1; the second non-circular gear pump 13 has a second liquid inlet C1 and a second liquid outlet C0, and the second non-circular gear pump 13 is connected to the output shaft of the water-based hydraulic drive device 1.

[0027] In the specific implementation of the present invention, water is input through the first liquid inlet B1, and emulsified oil is input through the second liquid inlet C1; driven by the water-based hydraulic drive device 1, the first non-circular gear pump 16 operates to output a preset amount of water through the first liquid outlet B0; driven by the water-based hydraulic drive device 1, the second non-circular gear pump 13 operates to output a preset amount of emulsified oil through the second liquid outlet C0. The output water and emulsified oil are pumped into the stirring and mixing chamber for stirring to form an emulsion of a specific concentration.

[0028] Specifically, the water-based hydraulically driven emulsion proportioning device of the present invention adopts a water-based hydraulic driving device 1 as a power source, specifically a water-based non-circular gear motor, and a high-pressure water-based working medium or a filtered high-pressure water medium enters the motor from the water-based liquid inlet A1 at the rear end of the water-based non-circular gear motor, and converts the hydraulic energy into the output shaft kinetic energy of the motor through the non-circular gear system, and the formed low-pressure working medium returns to the pump station tank from the water-based liquid outlet A0 at the front end of the water-based non-circular gear motor. The output kinetic energy of the water-based non-circular gear motor is transmitted to the first non-circular gear pump 16 and the second non-circular gear pump 13 through gear meshing. As the main shafts of the two non-circular gear pumps rotate, a liquid cavity with a periodic volume change is formed inside, thereby completing quantitative liquid suction and discharge actions.

[0029] During the rotation of the main shafts in the first non-circular gear pump 16 and the second non-circular gear pump 13, the filtered water and emulsified oil are sucked from the single medium storage tank into the corresponding non-circular gear pumps through the first liquid inlet B1 and the second liquid inlet C1, respectively, and the filtered water and emulsified oil are respectively discharged through the first liquid outlet B0 and the second liquid outlet C0 and pumped into the stirring and mixing chamber, thereby completing the mixing of the emulsion in a specific ratio.

[0030] Generally, the first non-circular gear pump 16 and the second non-circular gear pump 13 use gear pumps with different displacements to meet the requirements of the emulsified oil ratio. According to actual conditions, in order to ensure that the emulsion concentration is 3%-5%, the internal gear transmission ratio of the two non-circular gear pumps can be adjusted accordingly.

[0031] It can be seen that the water-based hydraulically driven emulsion proportioning device provided by the present invention has the following beneficial effects: 1.

Two non-circular gear pumps are driven simultaneously by a water-based hydraulic drive device 1, ensuring that the speed ratio of the main shafts of the two non-circular gear pumps remains stable, with high transmission accuracy, reliability and economy, and ensuring a stable ratio of water and emulsified oil output; 3. Two non-circular gear pumps with different displacements are used, which are driven simultaneously by speed-increasing gear transmission. The ratio of the extracted filtered water and emulsified oil is determined by its inherent displacement and speed ratio relationship to ensure the concentration of the emulsified oil. The control method is simple and accurate, and the reliability and stability are excellent. 4. The non-circular gear pump used has the advantages of small size and large displacement. Its main shaft rotates one circle, and its internal chamber can suck and discharge liquid dozens of times, which is more efficient than the axial liquid-inlet electric impeller water pump.
