It states acquisition platform and pushes ore pulp flowing.The exciting device is made of two shock electric machines, the central axis both ends of each shock electric machine
With etc. quality, same-phase eccentric mass, two shock electric machines synchronous opposite directions rotation when work provides flat with above-mentioned collection
The vertical vibration in the inclination angular direction of platform, plays a role in promoting to ore pulp, it is promoted to accelerate to flow to collecting pit 8.When being collected into
Foam or formation fluidity of slurry it is not so good when, can install and use the exciting device.
Foam collection device of the invention is described further combined with specific embodiments below.
The foam collection device of the floatation equipment of the present embodiment, it is good to the ore pulp adaptability of various mineral, it can be collected simultaneously
Foam in larger range improves flotation operation efficiency.As shown in Figure 1, the foam collection device includes: acquisition platform, acquisition
Cover, collecting pit, blower, air piping etc. further can also include ore slurry pipeline and ore slurry pump；The collection device is floated with existing
Optional equipment to scrape the foams collection device design features such as bubble different, be using collector by negative pressure by the foam of froth bed more
On a large scale, it acquires rapidly, in time, reduce foam dead zone and avoids froth bed desiccation, landslide and rupture, after foam collection
The mixture ore pulp of both solid, air-liquid three or solid, liquid is formed in collector, mixture ore pulp enters receipts through diversion trench
Collect in pond, then the next workflow in dressing plant will be sent to by pump, mixture pipeline in time, and complete the acquisition mesh of foam
, improve the efficiency of floatation equipment and ore-dressing practice.
It is uniformly distributed on the acquisition platform of the collection device to have multiple honeycomb holes, n are shared, the vertical section of each honeycomb hole
In the shape of a trumpet, upper opening is small, under shed is big, and the upper opening endoporus area of a honeycomb hole is a.Adjacent cell is formed between hole
There is height difference, convenient for the formation of foam ore pulp being collected between the upper opening of the diversion trench being connected in length and breadth, diversion trench and honeycomb hole
And confluence.It is floatation equipment main shaft via hole that acquisition platform, which is equipped with 1 biggish via hole, so that the main shaft of floatation equipment can be by this
Hole enables foam collection device smoothly to install.
The acquisition cover of the collection device be located in the accommodating cavity that an acquisition foam is formed on acquisition platform, and air piping connects
It connects and is above connected to in accommodating cavity body in acquisition cover, collecting pit is located at acquisition platform side, exports and connects with the diversion trench of acquisition platform
It connects, the bottom of collecting pit is lower than acquisition platform, height difference h, and the width of collecting pit is k；The bottom both sides of collecting pit length direction
Height, it is intermediate low, it is more advantageous to the flowing and concentration of ore pulp Yu foams mix body in this way.
The blower of the collection device uses industrial centrifugal blower, and for providing negative pressure, blower passes through air piping and acquisition
Cover connection, the air quantity of blower are Q, Q=n × a × v, and wherein v is wind speed, and n is the quantity of the honeycomb hole of acquisition platform, and a is one
The upper opening endoporus area of honeycomb hole.The blower can also be other kinds of according to the different ore dressing occasions selection that floatation equipment is applied
Blower.
The ore slurry pipeline that can also set external ore slurry pump and be connected between the ore slurry pump and collecting pit of the collection device,
For the mixture being collected into collecting pit to be conveyed next ore dressing link.
In work, foam is full of above floatation equipment container, the blower of the foam collection device of the present embodiment works, provides
Negative pressure, allows the continuous fast Acquisition foam of acquisition platform, and by foam collect into acquisition platform honeycomb hole, foam passes through honeycomb
Become ore pulp behind hole, flow to surrounding along the upper opening of each honeycomb hole, and be pooled in the diversion trench of acquisition platform upper end, passes through
Diversion trench flows in collecting pit.
If mobility of the ore pulp for the formation of foam collected in diversion trench is bad, the acquisition platform of collection device is set
Lesser inclination angle is set, to enhance mobility of the ore pulp in diversion trench.Inclination angle cannot be excessive, generally less than 10 °, avoid because
It tilts excessive and leads to foam collecting effect there are larger differences.It is excessively poor for the higher mobility of sticky biggish or concentration
The ore pulp being collected into, if installation is by vibration excitor on foam trap for design, shock electric machine, partially after designed inclination angle
The exciting device that heart quality axis is constituted, wherein eccentric mass axis is vertical with the inclination angular direction of the collection device, vibration excitor
It plays a role in promoting to ore pulp, it is promoted to accelerate to flow to collecting pit.
Ore slurry pump passes through ore slurry pipeline for the pulp conveying in collecting pit to next ore dressing link, arrives this, completes all
Foam collection work.
In floatation equipment work, mineral syrup liquid can change, that is, the position of froth bed can change, and adjust acquisition platform
Position.It is realized by setting height adjustment device, height adjustment device is by liquidometer and the driving device for connecting acquisition platform
It constitutes, the method for adjustment of acquisition platform height is to install liquidometer in floatation equipment container and detect liquid level, it is defeated to will test result
Enter the controller to driving device, controller is according to the height for being arranged or operating adjust automatically acquisition platform, and then whole is received
The height of acquisition means, to adapt to the variation of liquid level, froth bed position.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Within the technical scope of the present disclosure, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Subject to enclosing.
