Description

ALL-IN-ONE MACHINE FOR CRUDE ORE INTERCEPTING AND SELECTING
TECHNICAL FIELD The present invention belongs to the technical field of mineral flotation, and particularly relates to an all-in-one machine for interception and flotation.
BACKGROUND In order to effectively separate useful minerals from gangue minerals, in flotation technology, foaming agents are often used to generate a large amount of foam and form a large amount of liquid-gas interface. When useful minerals are enriched at the liquid-gas interface, they float up and separate from the gangue, which is called flotation. Flotation has strict requirements on the size, brittleness, toughness, and strength of the foam. It does not only need to be foamed; in general, coarse particle flotation requires large bubbles and fine particle flotation requires micro bubbles. However, in actual operation, there are both coarse ore particles and fine ore particles in the slurry, which places severe requirements on the accuracy of the flotation operation. A slight improper operation may cause the flotation efficiency to fail to optimize. Because the coarse ore particles in the slurry are beneficial components, and the fine ore particles contain both beneficial and useless components; then, it is an urgent technical problem to develop a new structure that can intercept coarse ore particles in advance and send fine ore particles into the flotation process, so as to screen out coarse ore particles that consume reagents but are not conducive to the flotation process, and realize the saving of flotation reagents and the high efficiency of the flotation process.
SUMMARY The purpose of the present invention is to overcome the shortcomings of the prior art, and to provide an all-in-one machine for interception and flotation with a reasonable and compact structure, which can intercept coarse ore particles in advance and send fine ore particles to the flotation process, thereby simultaneously ensuring the purpose of high-efficiency flotation operation on the basis of saving flotation reagents. In order to achieve the above purpose, the present invention adopts the following technical solution:
An all-in-one machine for interception and flotation, comprising a flotation barrel, wherein an overflow collecting tank is located at a mouth of the flotation barrel for discharging concentrates by flotation, and a tailings discharging pipe for discharging tailings is arranged at a bottom of the flotation barrel; wherein, a rotary drum is arranged in the flotation barrel, a rotary axis of the rotary drum is vertically arranged, and sieve holes for ore particles with specified particle sizes to pass through are arranged at a wall of the rotary drum; a top end opening of the rotary drum is communicated with an ore pulp feeding pipe and a bottom end opening is communicated with a coarse ore particle discharging pipe; the machine further comprises a bubble generator which is arranged in a barrel cavity of the flotation barrel and positioned below the rotary drum.
Preferably, the all-in-one machine for interception and flotation comprises a power motor as a power source, a power output shaft of the power motor extends vertically downward and is coaxially arranged with a driving gear, a section of the drum outside the flotation barrel is coaxially arranged with a driven gear, and the driving gear and the driven gear form a meshing fit.
Preferably, the rotary drum comprises a straight drum section and a tapered drum section which are arranged vertically from top to bottom in sequence, wherein the straight drum section constitutes a matching section for fixedly connecting the driven gear, while the tapered drum section constitutes a mesh screen section extending into the barrel cavity of the flotation barrel; slip rings or sealing rings are arranged at a top opening of a drum body of the straight drum section and a bottom opening of a drum body of the tapered drum section, while sealing rings or slip rings are correspondingly arranged at pipe ends of the corresponding ore pulp feeding pipe and the coarse ore particle discharge pipe; rotary sealing fit is formed between the top opening of the drum body of the straight drum section and the ore pulp feeding pipe, and between the bottom opening of the drum body of the tapered drum section and the coarse ore particle discharging pipe.
Preferably, the appearance of the flotation barrel is a barrel-shaped structure with a vertical axis, and the bottom of the flotation barrel is a bell mouth structure with a gradually decreasing inner diameter from top to bottom; the bubble generator, the rotary drum and the coarse ore particle discharge pipe are all arranged coaxially with the flotation barrel.
The method has the following beneficial effects:
1) many defects, such as low flotation efficiency, large medicine waste and the like caused by the traditional ore pulp directly entering the barrel to participate in flotation, are abandoned. In the present invention, a rotary drum with a centrifugal screen function is preset in the flotation barrel, so that when the rotary drum rotates, the surrounding ore pulp can be driven to rotate together. When working, coarse ore particles with a particle size larger than the sieve pores will stay in the drum, and move downward under the action of gravity, and finally be discharged from the coarse ore particle discharge pipe; while fine ore particles with a particle size smaller than the pore size of the sieve pores and water in the ore pulp pass through the sieve pores and enter the flotation space in the barrel cavity of the flotation barrel. At this time, a large number of bubbles are generated by the bubble generator, and the bubbles collide with the fine ore particles. The hydrophobic ore particles adhere to the bubbles and float to the liquid level, overflow into the overflow collection tank and are discharged as concentrate, while the hydrophilic ore particles settle to the bottom of the barrel and are discharged as tailings through the tailings discharge pipe.
At this point, on the one hand, the present invention realizes the function of pre-intercepting coarse ore particles by adding the pre-intercepting coarse process, ensuring that only fine ore particles can enter the flotation space, and the foaming property of coarse ore particles is not needed during flotation, thereby reducing the difficulty of flotation and saving flotation reagents; on the other hand, due to the existence of the rotary drum, the fine ore particles in the flotation barrel always generate centrifugal force moving outwards, and spontaneously move towards the barrel wall, and bubbles also move towards the barrel wall, so the collision probability between the fine ore particles and bubbles will be increased when both the fine ore particles and bubbles are concentrated on the barrel wall, which is beneficial to the flotation results. In addition, bubbles and fine ore particles will float upwards after adhering to each other. Due to the centrifugal movement of the drum, bubbles and ore particles are concentrated near the wall of the flotation barrel after floating to the liquid surface. There is no bubble-ore particle adhesion in the central area of the liquid surface of the flotation barrel. Therefore, there is no bubble-ore particle adhesion stuck in the flotation barrel, which is very beneficial to flotation. Finally, the bubble-particle adhesion around the liquid surface of the flotation barrel is constantly "topped" upward by the bubble-particle adhesion below, and overflows into the overflow collection tank more quickly, which is obviously beneficial to the flotation results. Practice proves that the diversity advantages of the present invention can effectively improve the actual flotation efficiency. 2) As a further preferred solution of the above solution, the drum works according to the gear transmission principle, and the power motor is used as the power source to realize the self-rotation effect of the drum. The two axial ends of the drum are matched with the ore pulp feeding pipe and the coarse ore particle discharging pipe in a rotary sealing way respectively, so that the stable centrifugal rotation effect of the drum itself can be ensured while realizing the double-end fixed function similar to the Charpy type. It is worth noting that the lower half section of the rotary drum, that is, the section extending into the cavity of the flotation barrel to participate in the screening of coarse ore particles, should have a tapered section structure with a thick top and a thin bottom, so as to improve the actual screening effect. 3) In order to improve the actual flotation effect, the bubble generator, the rotary drum and the coarse ore particle discharge pipe are all coaxial with the flotation bucket, so as to ensure that the centrifugal force generated by the rotating action of the rotary drum can be balanced in the cavity of the flotation barrel. The bottom of the flotation barrel presents a bell mouth structure with the inner diameter gradually decreasing from top to bottom, which is beneficial to tailings blanking.

DESCRIPTION OF EMBODIMENTS For convenience of understanding, the specific structure and working mode of the present invention will be further described below with reference to Fig.1. Referring to Fig. 1, the specific structure of the present invention includes a cylindrical flotation barrel 10, on which an overflow collecting tank 11 is arranged to collect concentrates; the bottom of the flotation barrel 10 is bell-shaped to facilitate tailings falling and collecting, and the bottom of the flotation barrel 10 is directly communicated with a tailings discharge pipe 12; a bubble generator 50 is also arranged in the barrel cavity of the flotation barrel 10 to realize the bubble flotation function.
At the same time, a centrifugal coarse ore intercepting system shown in Fig. 1 is coaxially arranged in the barrel cavity of the flotation barrel 10, so as to realize the pre-intercepting effect of coarse ore particles in the pulp, improve the flotation efficiency and save the flotation agent.
Wherein: The centrifugal coarse ore intercepting system includes a first dynamic sealing component 71, a power assembly, a rotating drum 20, a second dynamic sealing component 72 and a coarse ore particle discharge pipe 40 which are sequentially arranged from top to bottom.
The first dynamic sealing component 71 and the second dynamic sealing component 72 can adopt the conventional dynamic sealing structure of slip rings and sealing rings, which aims at ensuring the self-rotation function of the rotary drum 20 and the sealing connection between the rotary drum 20 and the ore pulp feeding pipe 30 and the coarse ore particle discharge pipe 40. In assembly, as shown in Fig. 1, the first dynamic sealing component 71 is arranged at the matching end of the straight drum section 21 and the ore pulp feeding pipe 30, and then the second dynamic sealing component 72 is arranged at the matching end of the tapered drum section 22 of the drum 20 and the coarse ore particle discharge pipe 40. The power component includes a power motor 61, a driving gear 62 and a driven gear 63 engaged with each other.
The driven gear 63 is coaxially arranged on the straight drum section 21, while the driving gear 62 is coaxially arranged on the power output shaft of the power motor 61, so as to form a power meshing structure as shown in Fig. 1. As for the bubble generator 50, it needs to be coaxially arranged just below the drum 20, so that the generated bubbles can be caught by the centrifugal vortex generated by the rotation of the drum 20 in time and quickly during the rising process, and the purpose of efficient flotation operation can be achieved.
In the specific operation of the present invention, first, the power motor 61 is turned on to rotate the rotary drum 20. Thereafter, the ore pulp begins to enter the drum cavity of the rotary drum 20 through the ore pulp feeding pipe 30. At this time, coarse ore particles with a particle size larger than the pore size of the sieve pores will remain in the rotary drum 20, and will move downward under the action of gravity, and finally be discharged from the coarse ore particle discharge pipe 40. Fine ore particles with a particle size smaller than the pore size of the sieve pores enter the flotation space in the barrel cavity of the flotation barrel 10 together with the water in the pulp through the sieve pores. At this time, a large number of bubbles are generated by the bubble generator 50, and the hydrophobic ore particles adhere to the bubbles and float up to the liquid surface, overflow into the overflow collection tank 11 and then are discharged as concentrates, while the hydrophilic ore particles settle to the bottom of the barrel and are discharged as tailings through the tailings discharge pipe 12, finally achieving the predetermined purpose of interception and flotation.
Of course, the above is one of the specific embodiments of the present invention. In actual operation, equivalent replacement of the shape of the flotation barrel 10 as the main carrier, such as replacing it with a square tank or even a spherical body, or making conventional position adjustment of the bubble generator 50 without affecting its function, or even making the whole rotary drum 20 with a screen, etc., such conventional structural changes under the premise of the structure of the present invention should fall into the protection scope of the present invention as equivalent or similar designs.
