Description
Technical field
The invention belongs to ceramic membrane filter technical fields, and in particular, to a kind of to recycle cutting fluid with ceramic membrane filter
Method.
Background technology
With the fast development of modern mechanical manufacturing industry, cutting fluid is widely applied in mechanical processing, and dosage is fast
Speed increases.But cutting fluid becomes industrial wastes using that will fail after certain time limit.The main reason for cutting fluid fails be it
People some impurity are inevitably mixed during recycling, such as metallic (chip), dust, abrasive material powder, fiber, free
Miscellaneous oil, the water etc. in cutting oil.When these impurity contents are higher, cutter and surface to be machined can be impaired in use.
Furthermore these impurity are the dominant catalysts of cutting fluid oxidation deterioration, they can accelerate cutting fluid chemical change cause it is higher
Acidity and larger interfacial tension so that cutting fluid deterioration failure.How purifying cutting fluid to be handled, it is made to make profits again
With, it has also become an important topic of Modern Cutting Fluids research.
General enterprises are commonly used at present：Biochemical process, coacervation, gravitational separation process, the precipitation method, aeration, electrolysis, Bubble-floating Method
It is handled Deng to cutting fluid.The waste oil in the recyclable cutting fluid of processing by above-mentioned several techniques, but cutting fluid can not be made
It is back to production.
The content of the invention
For the deficiencies in the prior art in above-mentioned background technology, the present invention provides a kind of recycled with ceramic membrane filter to cut
The method of liquid by using ceramic membrane technology, can be purified cutting fluid, and be back in production and processing.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of method with ceramic membrane filter recycling cutting fluid includes the following steps：
(1) cutting fluid for producing discharge is collected and deposited in subsider, divided the oil slick on upper strata by Oil scraper
It leaves, oil slick is exported by oil guide pipe to waste oil collecting barrel；
(2) cutting fluid of subsider is extracted by elevator pump in collecting tank, again by Oil scraper by the oil slick on upper strata
It separates, oil slick is exported by oil guide pipe to waste oil collecting barrel, and the cutting fluid in collecting tank is pumped into nothing by coolant conveying
In the circulating slot of machine ceramic membrane separation system；
(3) under pressure, cutting fluid flows through inorganic ceramic membrane group, enters recycling liquid bath by the cutting fluid of film group；
The suspended particulates such as abrasive dust are rejected by forming concentrate, back to circulating slot, continue filtering operating；
(4) by the cutting fluid of inorganic ceramic membrane group filtering, ultraviolet lamp tube is flowed through and by sterilization into after recycling liquid bath
Handle backward Grinding machine shops feed flow.
Cutting fluid crosses membrane operations pressure as 0.15-0.3MPa, crossflow velocity 4-5m/s in the step (3), crosses film temperature
It spends for 35-50 DEG C.
Inorganic ceramic membrane group is using α-Al in the step (3)2O3-ZrO2Inorganic ceramic membrane, aperture 50-70nm.
Ultraviolet lamp tube selects power 8W, wavelength 365nm or power 15W in the step (4), and wavelength 302nm's is ultraviolet
Fluorescent tube.
Beneficial effects of the present invention：
The present invention recycles cutting fluid by using inorganic ceramic membrane technical filter, can realize the purification to cutting fluid and return
It receives, pollutant oil, bacterium and the impurity in cutting fluid are removed, and are remained the primary raw material surfactant of cutting fluid, prevented
Rotten agent, fungicide etc. realize the effective recycling of cutting fluid, and organic efficiency is high, has saved production cost；The method of the present invention
Simply, operation is easy, suitable for pushing to run on a large scale；The present invention is also carried out at sterilization recycling cutting fluid using ultraviolet lamp tube
Reason can dispose the bacterial pollutant in cutting fluid, purify cutting fluid.
Description of the drawings
In order to facilitate the understanding of those skilled in the art, the present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is a kind of method flow diagram that cutting fluid is recycled with ceramic membrane filter of the present invention.
Specific embodiment
Technical scheme is clearly and completely described below in conjunction with embodiment, it is clear that described reality
It is only part of the embodiment of the present invention to apply example, instead of all the embodiments.Based on the embodiments of the present invention, this field is general
All other embodiment that logical technical staff is obtained without creative efforts belongs to what the present invention protected
Scope.
A kind of method with ceramic membrane filter recycling cutting fluid, as shown in Figure 1, including the following steps：
(1) cutting fluid for producing discharge is collected and deposited in subsider, divided the oil slick on upper strata by Oil scraper
It leaves, oil slick is exported by oil guide pipe to waste oil collecting barrel；
(2) cutting fluid of subsider is extracted by elevator pump in collecting tank, again by Oil scraper by the oil slick on upper strata
It separates, oil slick is exported by oil guide pipe to waste oil collecting barrel, and the cutting fluid in collecting tank is pumped into nothing by coolant conveying
In the circulating slot of machine ceramic membrane separation system；
(3) under pressure, cutting fluid flows through inorganic ceramic membrane group, enters recycling liquid bath by the cutting fluid of film group；
The suspended particulates such as abrasive dust are rejected by forming concentrate, back to circulating slot, continue filtering operating；
Wherein, cutting fluid crosses membrane operations pressure as 0.15-0.3MPa, crossflow velocity 4-5m/s, and it is 35-50 to cross film temperature
℃；Inorganic ceramic membrane group is using α-Al2O3-ZrO2Inorganic ceramic membrane, aperture 50-70nm；α-A l2O3-ZrO2It is inorganic
