Description
Technical field
The present invention relates to magnet manufacture field, be specifically related to the process for separating and recovering of a kind of magnetic mud material.
Background technology
Neodymium iron boron blank can produce substantial amounts of magnetic during machining makes neodymium iron boron magnetic body
Pug, mainly contains iron powder, rare-earth metal powder and cutting oil in magnetic mud material, these magnetic mud material are discarded
Processing and not only pollute environment, and waste resource, for this, most enterprises all can be in magnetic mud material now
Iron powder, rare earth metal and oil carry out recycling, at the rare earth metal reclaimed in magnetic mud material
During material, how realizing oil separating in magnetic mud material is one of key technology, prior art
In generally by atmosphere burning or in water the method for high temperature alkali cooking carry out separate oil removing,
But using said method oil removing to need to consume substantial amounts of energy resource, cost recovery is high, and metal
The response rate of raw material is low, it is difficult to meet enterprise's requirement to energy saving and cost lowering.
Summary of the invention
It is an object of the invention to provide a kind of low cost, the separation and recovery work of the magnetic mud material that the response rate is high
Skill.
For achieving the above object, present invention employs techniques below scheme: the separation of a kind of magnetic mud material
Recovery process, it comprises the following steps:
S1) in reaction tank, magnetic mud material and water, stirring mixing are put into according to the mass ratio of 1:2.5-4；
S2) start supersonic gas vibrating device and the mixed liquor in reaction tank is carried out supersonic oscillations process
5-20min, stands 15-30min and is layered to mixed liquor；
S3) the most successively the oil reservoir in reaction tank, water layer are discharged and collected, finally remain in
The material slag being containing metalliferous material in reaction tank.
Use having the beneficial effects that of technique scheme generation: the application uses at supersonic oscillations
The magnetic mud material produced during reason processing neodymium iron boron magnetic body, the elaioleucite in mixed liquor in oscillatory process
Vibrating together with mixed liquor medium, the particle owing to varying in size has different vibration speed
Degree so that elaioleucite mutually collides, bonds, and volume and weight is gradually increased, and final granule is bigger
Oily substance is gradually disengaged out and floats on the upper strata of reaction tank, solid-state after standing a period of time
Material slag deposits, in the bottom of reaction tank, the most first will be located in the oily substance on reaction tank upper strata from fuel-displaced
Mouth is discharged and is collected, and is then discharged from discharge outlet, finally by the water layer between oil reservoir and material slag blanket
Remain in the material slag being containing metalliferous material in reaction tank, so achieve in magnetic mud material
Oil separates and collects with metalliferous material.In actual separation removal process, described supersonic gas vibrating dress
Put both can be to implement oscillation treatment with the mixed liquor mediate contact in reaction tank, it is also possible to such as this Shen
Shown in accompanying drawing 1 please, the mixing that the head that shaken by the gas of sound wave gas vibrating device is directly inserted in reaction tank
Mixed liquor carries out in liquid oscillation treatment, and certainly, described mixed liquor both can be placed in individually reaction
In pond, then by supersonic gas vibrating device, the mixed liquor in reaction tank is carried out at supersonic oscillations
Reason, it is also possible to mixed liquor is directly thrown into the gas that supersonic gas vibrating device self the includes indoor that shake and adds
With oscillation treatment.Compared with prior art, technical scheme disclosed in the present application is used not only to separate back
Receive the low cost of magnetic mud material, and easily realize, after testing, reclaim oil in the oily substance obtained
High purity more than 94%, reclaim the content of oil in the material slag obtained and less than 5%, efficiently separate
Go oil removing, and then provide convenient for the metalliferous material in postorder recycling material slag.
As further preferred version: the ultrasonic frequency of described supersonic gas vibrating device is
25KHz-33KHz, optimal, the ultrasonic frequency of described supersonic gas vibrating device is 30KHz, warp
Cross substantial amounts of verification experimental verification, use the ultrasound wave of this frequency effectively to be shaken by the oil in mixed liquor
Swing and separate.
More specifically scheme is: the time of described stir process is 5-20min, and mixing speed is
65-75r/min, optimal, the time of described stir process is 15min, and mixing speed is
70r/min, it addition, with prior art by burning in atmosphere or high temperature alkali cooking in water
Method carries out separating the technical scheme of oil removing and compares, and technical scheme disclosed in the present application is to mixed liquor
Temperature conditions requires low, effectively save energy consumption, reduces processing cost, concrete, described reaction tank
Temperature in 10 controls at 5-25 DEG C, and optimum temperature is controlled at 15-20 DEG C, in this temperature conditions
Oily substance in lower mixed liquor can speed up separation and floats, and significantly shortens process for separating and recovering
The required time.
