[0002] Flotation agents are chemicals used in the mineral flotation process. They can adjust the surface properties of minerals, increasing or decreasing their floatability, and improving the pulp properties and foam stability for better mineral separation. Before use, flotation agents must be emulsified to disperse them evenly throughout the slurry as an emulsion. This increases the contact area between the agent and the mineral particles, thereby improving their efficiency.

DETAILED DESCRIPTION

[0021] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0022] Please see the attached Figure 1 As shown, a flotation reagent strong shear emulsification device includes a water inlet pipe 1, a mixing chamber 2, and a cavitation chamber 6 connected in sequence from top to bottom. The mixing chamber 2 includes an outer shell 201, a plurality of frother tubes 202 and a collector tube 204 arranged on the surface of the outer shell 201 and communicating with the interior of the outer shell 201, and a support plate 203 is provided inside the outer shell 201. The support plate 203 is provided with a plurality of nozzles 4 corresponding to the number of frother tubes 202.

[0023] The plurality of nozzles 4 are arranged in a spiral shape around the central axis of the outer shell 201, so that the water entering the nozzle 4 spirals downward into the cavitation chamber 6, thereby realizing a water swirling jet. The jet action can form a negative pressure in the mixing chamber 2, and the swirling jet of water or slurry liquid can reduce the risk of slurry blockage.

[0024] A medicine tube 404 connected to the foaming agent tube 202 is provided in the nozzle 4. The medicine tube 404 is coaxially arranged with the nozzle 4. After the medicine is ejected from the medicine tube 404, it is fully rotated and mixed with the water ejected in a swirling manner. A plurality of guide plates 403 are also provided in the nozzle 4.

[0025] Please see the attached Figure 2-4 As shown, the support plate 203 is provided with mounting holes corresponding to the number of the foaming agent tubes 202, and the nozzle 4 includes a conical shell 402 and a positioning ring 401 arranged on the upper edge of the conical shell 402. The diameter of the positioning ring 401 is larger than the diameter of the mounting hole. The conical shell 402 is installed on the support plate 203 through the mounting hole and the positioning ring 401. One foaming agent tube 202 corresponds to one nozzle 4.

[0026] In the above embodiment, preferably, a pressure plate 3 with the same shape as the support plate 203 is further provided above the nozzle 4, which is used to press and stabilize the nozzle 4. The pressure plate 3 is provided with circular holes corresponding to the mounting holes one by one, so as not to affect the normal passage of the liquid. The liquid enters the mixing chamber 2 from the water inlet pipe 1 above, and then passes through the mixing chamber 2 into the nozzle 4, and finally is sprayed out from the nozzle 4.

[0027] The outer side 4031 of the guide plate 403 is connected to the inner wall of the conical shell 402 , and the inner side 4032 of the guide plate 403 is connected to the outer wall of the medicine tube 404 . The medicine tube 404 is fixed in the conical shell 402 through the guide plate 403 .

[0028] Specifically, as attached Figure 4 and attached Figure 5 As shown, the outer side 4031 of the guide plate 403 is a conical spiral, and the taper of the conical spiral is the same as the taper of the conical shell 402. The inner side 4032 of the guide plate 403 is a cylindrical spiral, and the radius of the cylindrical spiral is the same as the outer diameter of the medicine tube 404. That is, the guide plate 403 as a whole presents a spiral sheet structure, which can make the liquid ejected in a spiral shape, so that it is fully mixed with the medicine at the end of the medicine tube 404 in the nozzle 4.

[0029] The mixing chamber 2 is further provided with a plurality of connecting tubes 5 , both ends of which are respectively connected to the foaming agent tube 202 and the medicine tube 404 . The connecting tubes 5 are bent and can be made of flexible materials.

[0030] The bubbling agent tube 202 is arranged above the support plate 203 , and the collecting agent tube 204 is arranged below the support plate 203 .

[0031] Working principle:

[0032] Water flows through the water inlet pipe 1 and the mixing chamber 2 in sequence and enters the nozzle 4. Since a guide plate 403 is set up in the nozzle 4, a water swirling jet can be realized. The jet effect can form a negative pressure in the mixing chamber 2. The frother reagent is sucked into the mixing chamber 2 through the frother pipe 202, the connecting pipe 5, and the reagent pipe 404. The collector reagent is sucked into the mixing chamber 2 through the collector pipe 204. The water swirling jet can strongly shear and emulsify the frother reagent and the collector reagent, so that the water, frother reagent, and collector reagent are fully mixed and mineralized, thereby improving the selectivity of the flotation reagent for fine-grained coal slime, reducing reagent consumption, and enhancing the flotation effect.

[0033] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0034] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
