A steady flow tank is communicated with the FCSMC, and a first rubber pipe valve is arranged on a communication pipeline. The device stabilizing liquid level of the FCSMC improves stabilization of the liquid level of the FCSMC, and is beneficial to controlling the liquid level, improves the quality of concentrate ore products, reduces mutual containing or product recovery rate and guarantees continuous and stable production.
Description
Technical field
The utility model relates to the ore dressing production technical field, specifically refers to a kind of device of stable cyclone-static microbubble floatation column liquid level.
Background technology
The application of China's flotation column mainly contains two kinds: a kind of is cyclone-static microbubble floatation column; Another kind is the pneumo type flotation post; At present, all restrain in the copper mine copper molybdenum separation of produced in the Sol storehouse and to roughly select, selectedly selected 8 cyclone-static microbubble floatation columns altogether, the copper molybdenum mixes roughly selects, FCSMC4000-8000 is adopted in selected operation and each 2 of FCSMC3000-7000 flotation columns; The copper molybdenum separates employing but copper selects molybdenum technology; Roughly select with 1 FCSMC2000-8000; Selected respectively 1 of FCSMC1000-7000, FCSMC800-7000, the FCSMC600-6000 that selects for use, purpose is to improve the classified and separated efficient of fine-grained copper molybdenum ore, optimizes product grade; Improve product recovery rate, simplify production technology; System adopts pressure transmitter-PLC automatic control system-mine tailing electric control valve (band valve position feedback) control; Through representative index such as table 1 after debugging in early stage, the operation.But adopt flotation column to press down in the floating molybdenum separation process of copper, because the molybdenum head grade is low, concentration ratio is less; Selected flotation column treating capacity is lower, and ore pulp has fluctuation or ore character that change is arranged slightly slightly, and the PLC automatic control system produces vibrations; Cause the flotation column liquid level to be difficult to reach balance, the control difficulty is bigger, and molybdenum concentrate grade is difficult to guarantee and molybdenum concntrate cupric height; The rate of recovery also is affected, and production stability is poor.

The utility model content
The utility model provides a kind of device of stable cyclone-static microbubble floatation column liquid level, can stablize selected flotation column liquid level and mine-supplying quantity, is beneficial to level control, and raising concentrate product quality, minimizing contain and product recovery rate mutually, guarantee to produce continual and steady.
For this reason, adopt following technical scheme: a kind of device of stable cyclone-static microbubble floatation column liquid level, comprise cyclone-static microbubble floatation column, be lower than its foam outlet place in the said cyclone-static microbubble floatation column and be provided with stabilier.
Current stabilization case and said cyclone-static microbubble floatation column are communicated with, and on this connecting pipeline, are provided with first hose valve.
The utility model is through disperseing bubble and ore pulp at the inner stabilier that increases of cyclone-static microbubble floatation column; Fluidised form and foam support power in the flotation column have been improved; And the gas that sucks is divided into the uniform tiny bubble of size; For flotation provides better bubble to distribute and two areas that contact, strengthened the secondary enrichment; Improve multistage orifice plate filling that flotation column operation conditions and separating effect divide selections and contained the flow disturbance of bottom eddy flow; In minute favored area, create one and both helped bubble mineralization; Help the floating and selected environment that separates of mineral laden bubble liter again, promoted the flotation column liquid level stabilizing.Thereby be beneficial to level control, raising concentrate product quality, minimizing contain and product recovery rate mutually, guarantee to produce continual and steady.
Description of drawings
Fig. 1 is existing cyclone-static microbubble floatation column structural representation sketch;
Fig. 2 is the structural representation sketch of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model and beneficial effect thereof are done further detailed explanation.
With reference to Fig. 2, a kind of device of stable cyclone-static microbubble floatation column liquid level comprises cyclone-static microbubble floatation column 9, is lower than its foam outlet 600mm place in the said cyclone-static microbubble floatation column 9 and is provided with stabilier 3, is uniformly distributed with through hole on this stabilier 3.
Current stabilization case 5 is communicated with said cyclone-static microbubble floatation column 9, on this connecting pipeline, is provided with first hose valve 4.
Be provided with baffle plate 6 in the said current stabilization case 5 and guarantee that the current stabilization case has constant level and its underpart to be provided with overflow launder 8 and makes mineral slurry flux return the conveying pump box.
The setting of above-mentioned current stabilization case; Changed the feed-type of existing cyclone-static microbubble floatation column; Pass through the current stabilization case earlier before making ore pulp get into cyclone-static microbubble floatation column; And it is big or small to regulate the mineral slurry flux that gets into cyclone-static microbubble floatation column through valve 4, and current stabilization case spillway discharge returns the conveying pump box through overflow launder 8, has guaranteed the constant mine-supplying quantity of selected flotation column.
The mine tailing pipeline of said cyclone-static microbubble floatation column 9 is provided with second hose valve 11; On this second hose valve 11 handle extension rod 1 is installed, this handle extension rod 1 extends to and places on the operating desk 10 that is lower than 1 meter of said current stabilization case 5 below and its upper end is equipped with handle 2.
Existing cyclone-static microbubble floatation column adopts pressure transmitter-PLC automatic control system-mine tailing electric control valve (band valve position feedback) control flotation column liquid level, and owing to sensible factors such as mineral slurry flux is little are disturbed, flotation column liquid level generation vibrations are bigger; The utility model utilizes common hose valve to replace electric control valve (reducing valve cost 85%); The hose valve joystick is extended to the flotation column operating platform; The operative employee is convenient to adjustment according to mineral slurry flux and ore change of properties; The method has replaced the PLC automatic control system, has made things convenient for operation, has guaranteed the flotation column liquid level stabilizing.
The utility model can be accomplished the separation of low-grade copper molybdenum ore effectively, has improved the efficiency of separation, output qualified concentrate product, each item index all reaches designing requirement, for enterprise has created considerable economic.Through representative index such as table 2 after debugging in early stage, the operation.
Table 2The Sol storehouse all restrains the operating index behind employing the utility model in the separation of copper mine copper molybdenum
The course of work of the utility model is following:
Ore pulp gets into the current stabilization case 5 from pulp-inlet pipe 7; In the current stabilization case, guarantee the constant level of baffle plate 6 height; Spillway discharge returns the conveying pump box through overflow launder 8; The flow size that 4 controls of first hose valve get into flotation column, second hose valve 11 is just accomplished whole control process through handle 2 control flotation column liquid levels.
