Abstract
The utility model discloses a kind of half self-priming bubble generator, comprise housing, in described housing, be provided with suction muffler, trunnion and anemostat, on described housing, be also provided with air inlet pipe, described air inlet pipe is provided with the second inlet channel of inflating for the first inlet channel of self-priming inflation with for outside.The utility model is simple in structure, solve because ore properties is of high grade, met the characteristic of floatation process requirement than the self-priming airing form difficulty of great flotation column, effectively improve the flotation efficiency of flotation column, stable concentrate is upgrade, improve concentrate yield, reduce tailings grade, reduce the unnecessary loss of resource.
Description
Technical field
The utility model relates to a kind of appurtenances of preparation equipment, especially relates to a kind of half self-priming bubble generator.
Background technology
The agent structure of existing eddy flow-state micro-bubble post screening installation comprises that flotation column divides selections (post separator), cyclonic separation section (cyclone separation device), flotation tube device three parts.Flotation tube device comprises bubble generator and flotation pipeline section two parts.It adopts the internal structure that is similar to jet pump bubble generator, has the double action (claiming again self-suction microbubble generator) that relies on jet flow negative pressure self introducing gas and gas is ground into bubble.Because of the characteristic of flotation column bubble generator structure, the inflation of bubble generator need rely on the negative pressure inflation of self.When the grade of ore is high, when great, the inflation of the bubble generator of flotation column self negative pressure cannot meet the needs of flotation air inflation amount, cause that flotation column Floatation Concentrate Grade is unstable, productive rate is on the low side, finally affected the tailings grade of whole series, caused the waste of resource.
Utility model content
For addressing the above problem, the utility model adopts following technical scheme:
A kind of half self-priming bubble generator, comprise housing, in described housing, be provided with suction muffler, trunnion and anemostat, on described housing, be also provided with air inlet pipe, it is characterized in that: described air inlet pipe is provided with the second inlet channel of inflating for the first inlet channel of self-priming inflation with for outside.
Access pulp-inlet pipe road from outside near trunnion, through pressurization ore pulp from pulp-inlet pipe road high velocity jet to trunnion, now, in trunnion porch because ambient air is swept away and forms vacuum by jet, according to the principle of Air Flow, air will flow from locations of high pressure to locations of low pressure, the first inlet channel is inhaled into suction muffler by extraneous air, at the same time, utilize outside air feed equipment to be filled with extra air, enter suction muffler from the second inlet channel, the Air Flow being filled with from the first inlet channel and the second inlet channel is to trunnion, sneak in ore pulp, enter anemostat through trunnion, in anemostat, be ground into bubble.
The second inlet channel can be located between the first inlet channel and suction muffler, and now, the first inlet channel and the second inlet channel can be two independently pipelines, can be also two inlet channels separating in air inlet pipe by dividing plate.
Air inlet pipe can be two, is respectively the first air inlet pipe and the second air inlet pipe.The first air inlet pipe is symmetrical with the relative housing shaft of the second air inlet pipe.Now, the first air inlet pipe communicates with the first inlet channel, and the second air inlet pipe communicates with the second inlet channel.
The first inlet channel is generally that equipment itself carries, and is that the general mineral floating of basis institute air demand is equipped with.And the second inlet channel is to use compressed air pressure value to configure according to the large mineral ore pulp of flotation density.Provide at external equipment under the air feed prerequisite of 28-30kPa steady pressure, preferably, the channel diameter of described the first inlet channel is the pipe diameter of air inlet pipe
the channel diameter of described the second inlet channel is the pipe diameter of air inlet pipe
The half self-priming bubble generator that the utility model provides, simple in structure, solve because ore properties is of high grade, met the characteristic of floatation process requirement than the self-priming airing form difficulty of great flotation column, effectively improve the flotation efficiency of flotation column, stable concentrate is upgrade, improve concentrate yield, reduce tailings grade, reduce the unnecessary loss of resource.

Detailed description of the invention
Embodiment 1:
As shown in Figure 1, bubble generator comprises housing 1, the cylindrical structure of housing 1, and its cross section is I shape.The two ends of housing 1 are flange end 11, and flange end 11 is provided with several installing holes 12.In housing 1, be provided with suction muffler 2, trunnion 3 and anemostat 4.Housing 1 one sides are also provided with air inlet pipe 5, and air inlet pipe 5 stretches in housing 1, are connected with suction muffler 2.Air inlet pipe 5 is provided with the second inlet channel 7 of inflating for the first inlet channel 6 of self-priming inflation with for outside.In the present embodiment 1, the pipe diameter of the first inlet channel 6 is air inlet pipe 5 pipe diameters
the pipe diameter of the second inlet channel 7 is air inlet pipe 5 pipe diameters
Utilize flange end 11 and installing hole 12 on housing 1 that bubble generator is quick installed on flotation device, now, the ore pulp runner 8 on flotation device is positioned near trunnion 3.Ore pulp through external equipment pressurization flows to nozzle 81 from ore pulp runner 8, from nozzle 81 high velocity jet to trunnion 3, now, in trunnion 3 porch because ambient air is swept away and forms vacuum by jet, according to the principle of Air Flow, air will flow from locations of high pressure to locations of low pressure, extraneous air is inhaled in air inlet pipe 5 from the first inlet channel 6, enter suction muffler 2 until air arrives trunnion 3 through air inlet pipe 5 again, at the same time, the gas being filled with through external equipment certain pressure enters bubble generator from the second inlet channel 7, the air inlet pipe 5 of passing through, suction muffler 2, arrive trunnion 3.In the present embodiment 1, outside the blowing pressure is selected 30kpa.Enter trunnion 3 from the first inlet channel 6 from the air sucking and the air being filled with from the second inlet channel 7, after mixing with ore pulp, enter anemostat 4, generate bubble in the interior pulverizing of anemostat 4.
Embodiment 2:
As shown in Figure 2, the difference of embodiment 2 and embodiment 1 is the position distribution of the first inlet channel 6 and the second inlet channel 7.In embodiment 2, the first inlet channel 6 and the second inlet channel 7 are all positioned at air inlet pipe 5, utilize dividing plate 9 that air inlet pipe 5 is separated into two parts.
Embodiment 3:
As shown in Figure 3, the difference of embodiment 3 and embodiment 1 is the position distribution of the first inlet channel 6 and the second inlet channel 7.In embodiment 3, housing is provided with two air inlet pipe 5, and air inlet pipe 5 stretches in housing 1, is connected with suction muffler 2.The air inlet pipe 5 of one side is provided with the first inlet channel 6, and the air inlet pipe 5 of opposite side is provided with the second inlet channel 7.
The half self-priming bubble generator that the utility model provides, simple in structure, solve because ore properties is of high grade, met the characteristic of floatation process requirement than the self-priming airing form difficulty of great flotation column, effectively improve the flotation efficiency of flotation column, stable concentrate is upgrade, improve concentrate yield, reduce tailings grade, reduce the unnecessary loss of resource.
