Description

Technical Field

[0001] The utility model relates to the technical field of ore dressing equipment, in particular to an environment-friendly lead-zinc ore flotation device. Background Art

[0002] In mineral processing, flotation is a commonly used separation method. Flotation, namely foam flotation, is a process of separating minerals from pulp by means of the buoyancy of bubbles based on the differences in the surface properties of various minerals. Its separation process is mainly carried out according to the differences in the physicochemical properties of the material surface. In order to improve the flotation effect, it is necessary to pre-treat the pulp. The specific process is to fully mix the pulp with reagents and air. Under the action of different reagents, the suspension of the pulp forms a hydrophilic or hydrophobic surface. The hydrophobic mineral particles effectively contact the rising bubbles and adhere to the bubbles to rise to form a foam layer, thereby realizing separation. The existing pre-treatment equipment for pulp flotation has a poor mixing effect on the pulp, which affects the flotation effect. Moreover, the pulp is easily attached to the inner wall of the equipment, resulting in waste of pulp and requiring manual cleaning. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is that the existing pre-treatment equipment for pulp flotation has a poor mixing effect on the pulp, which affects the flotation effect.

[0017] The utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0018] As Figures 1 to 3 shown, the environment-friendly lead-zinc ore flotation device of the utility model includes a tank body 11 with a discharge pipe 10 at the bottom. A rotating shaft 21 is arranged inside the tank body 11. A plurality of stirring blades 22 are fixedly arranged on the rotating shaft 21. A plurality of guide vanes 23 are arranged at intervals on the upper and lower surfaces of the stirring blades 22. A scraper 25 is fixedly arranged on the rotating shaft 21 through a connecting rod 24. The scraper 25 is spiral, and the outer surface of the scraper 25 is attached to the inner wall of the tank body 11.

[0019] The rotating shaft 21 drives the stirring blade 22 to rotate to stir and mix the pulp in the tank body 11. The guide vane 23 on the stirring blade 22 can improve the mixing effect and avoid affecting the flotation effect. At the same time, the rotating shaft 21 can drive the connecting rod 24 and the scraper 25 to rotate to scrape the pulp remaining on the inner wall of the tank body 11 and discharge it through the discharge pipe 10, avoiding waste of pulp and eliminating the need for manual cleaning.

[0020] Among them, at least two connecting rods 24 are arranged up and down to enhance the connection stability between the rotating shaft 21 and the scraper 25.

[0021] Among them, the spiral twisting direction of the scraper 25 should be coordinated with the rotation direction of the rotating shaft 21, so that when the scraper 25 rotates, the pulp remaining on the inner wall of the tank body 11 can be scraped from top to bottom.

[0022] Among them, the outer surface of the scraper 25 is provided with a wear-resistant layer.

[0023] Preferably, an electric push rod 26 is fixed on the tank body 11. The output end of the electric push rod 26 is fixed with a motor 27.

When the external spline 30 on the rotating shaft 21 is located in the circular hole 31, the output shaft of the motor 27 drives the rotating shaft 21 to rotate, driving the stirring blade 22 to rotate for stirring and mixing action. At this time, the scraper 25 stops operating. When the external spline 30 on the rotating shaft 21 slides upward along the circular hole 31 to cooperate with the internal spline 29, the output shaft of the motor 27 drives the rotating shaft 21 to rotate, driving the stirring blade 22 and the scraper 25 to rotate simultaneously, and performing the stirring and mixing action and the residual scraping action at the same time, so as to control the start and stop of the scraper 25 according to needs, meeting the actual application requirements.

[0025] Among them, see Figure 2 , both the upper and lower ends of the connecting cylinder 28 are hermetically connected to the rotating shaft 21.

[0026] Of course, a cylinder, a hydraulic cylinder or other mechanisms can also be used to replace the electric push rod 26.

[0027] Among them, the movement stroke of the output end of the electric push rod 26 can enable the external spline 30 to slide along the circular hole 31 to cooperate with the internal spline 29.

[0028] Among them, the external spline 30 and the internal spline 29 are tooth structures that cooperate with each other.

[0029] Preferably, the outer shell of the motor 27 is square. An installation box 32 is fixed on the top of the tank body 11. An electric push rod 26 is fixed on the installation box 32. The motor 27 is slidably arranged in the installation box 32.

[0030] The electric push rod 26 drives the motor 27 to move up and down along the installation box 32 without rotating, while avoiding damage to the motor 27 and the electric push rod 26.

[0031] Among them, the outer shell of the motor 27 can also be other non-circular structures, such as a notch shape.

[0032] Preferably, referring to Figure 1 , a through hole 33 is opened at the top of the tank body 11. The rotating shaft 21 passes through the through hole 33 and is arranged inside the tank body 11.

[0033] Preferably, a plurality of stirring blades 22 are spirally distributed from top to bottom, reducing the number of stirring blades 22 provided on the premise of ensuring the stirring and mixing effect.

[0034] Preferably, the stirring blade 22 is inclined relative to the horizontal plane to have an upward or downward pushing and mixing effect on the pulp in the tank body 11, improving the stirring and mixing effect.

[0035] Among them, the stirring blade 22 is arranged along the radial direction of the rotating shaft 21.

[0036] Preferably, referring to Figure 1 , 3 , the guide vane 23 is arranged along the width direction of the stirring blade 22, and the middle part of the guide vane 23 protrudes away from the stirring blade 22.

[0037] Among them, the outer surface of the guide vane 23 is a smoothly connected arc surface, and the widths of both ends of the guide vane 23 are smaller than the middle width, so as to achieve the effect of first dispersing and then mixing the pulp, further improving the stirring and mixing effect.

[0038] Preferably, an air inlet pipe 12 is provided at the top of the tank body 11, a feed pipe 13 and a water inlet pipe 14 are provided on the side of the tank body 11, and valves are provided on the air inlet pipe 12, the feed pipe 13, the water inlet pipe 14 and the discharge pipe 10.

The above pipelines can be selected and set according to actual applications. The specific setting method is the prior art and will not be elaborated here.

[0040] The working principle of the present utility model is as follows:

[0041] Air is introduced into the tank body 11 through the air inlet pipe 12, ore and other reagents are fed in through the feed pipe 13, and water is introduced into the tank body 11 through the water inlet pipe 14; the electric push rod 26 drives the motor 27 to move up and down along the installation box 32 to control the up and down movement of the rotating shaft 21. Specifically, when the external spline 30 on the rotating shaft 21 is located in the round hole 31, the output shaft of the motor 27 drives the rotating shaft 21 to rotate, driving the stirring blade 22 to rotate to stir and mix the pulp in the tank body 11. The guide vane 23 on the stirring blade 22 can improve the mixing effect and avoid affecting the flotation effect. At this time, the scraper 25 stops running; when the external spline 30 on the rotating shaft 21 slides upward along the round hole 31 to cooperate with the internal spline 29, the output shaft of the motor 27 drives the rotating shaft 21 to rotate, driving the stirring blade 22, the connecting rod 24, and the scraper 25 to rotate simultaneously, stirring and mixing the pulp in the tank body 11 and scraping the residual pulp on the inner wall of the tank body 11 at the same time, and discharging it through the discharge pipe 10 to avoid waste of pulp and eliminate the need for manual cleaning.
