Description
Technical field
The utility model relates to a kind of filter at liquid, relates in particular to a kind of filter that utilizes again at the used working solution of line cutting processing.
Background technology
The contaminant particles that dirty working solution after the line cutting processing contains mainly contains two classes, one class is the elaboration products solid particle that produces in the discharge process, its granularity is about more than the 5-8 μ m, another kind of is suspended contamination, its granularity is about below the 5-8 μ m, and the suspension diameter of particle that has has only 0.1-0.7 μ m.The dirty working solution circulated filter system of present wire electrode cutting machine bed uses the papery candle filter to filter usually, can only the solid particle of grade of filtration more than 5-8 μ m, and can not grade of filtration be the following suspension of 5-8 μ m.And along with constantly carrying out and the prolongation of filter service time of process, the probability that the papery candle filter can stop up strengthens, and filter effect can be worse and worse.Common way is to change filter and prepare the dirty working solution of replacing again, and this just causes filtering cost and strengthens.From line cutting processing effect; because filter effect is not good; the contaminant particles of dirty working solution can influence the conductivity variations of working media, thereby influences the variation of discharging gap and the stability of discharge process, and then influences the dimensional accuracy and the uniformity precision of part.In addition, because the filtration problem of dirty working solution is not resolved, for small discharging gap, the contaminant particles in the dirty working solution has influenced its flow field characteristic, has strengthened the resistance that dirty working solution enters discharging gap; Simultaneously also because the existence of the contaminant particles in the dirty working solution, the realization of high pressure hydrojet has been caused certain degree of difficulty, thereby restricted the development of wire cutting technology technology.In addition, because there is adverse effect in the discharging of the dirty working solution that changes to environment, also increased energy resource consumption.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of filter effect good, filter the low a kind of line cutting processing working solution filter of cost.
A purpose of the present utility model, to be achieved by the following technical programs: line cutting processing working solution filter, it is characterized in that: described filter comprises tank body and the filter core fixed head that is arranged in the tank inner chamber, the lower surface of described filter core fixed head is provided with one with upper filter, described filter core is the cavity cylinder that wall has micropore, is filtered particulate and forms adsorbed film at the filter core outer surface; The upper surface of described filter core fixed head is provided with the fluid pipeline that is communicated with the filter core inner chamber and the tank body outside, and the described tank body outside is provided with the input duct that feeds tank inner chamber.
Further, described filter core is high molecular polymer cavity cylinder or the ceramic cavity cylinder with micropore, and the aperture of described micropore is greater than the particle diameter that is filtered particulate.
Compared with prior art, usefulness of the present utility model is: this line cutting processing working solution filter good filtration effect, and the plugging rate that filter core takes place is little, and it is less to filter cost.
Description of drawings
Fig. 1 is a kind of line cutting processing of the utility model working solution filter structure schematic representation.
Fig. 2 is a kind of line cutting processing working solution filter work principle of filter schematic diagram.
The specific embodiment
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
A kind of line cutting processing working solution filter as shown in Figure 1, it comprises tank body 1 and the filter core fixed head 4 that is arranged in the tank inner chamber, the lower surface of this filter core fixed head 4 is provided with one with upper filter 5, illustrated embodiment is three filter cores, but the flow of the working solution when in actual applications, the quantity of filter core 5 (being filter area) is according to filtration is selected.And structure (as shown in Figure 2) from this filter core 5, it has the high molecular polymer cavity cylinder or the ceramic cavity cylinder of micropore 8 for wall, the aperture of micropore is greater than being filtered particulate 6, and those are filtered particulate 6 and form adsorbed film 9 at the filter core outer surface under tank body 1 inner chamber certain pressure condition.Herein, membrance casting condition as adsorbed film, the pore size of micropore in the filter core (being the filtering accuracy of filter) is determined according to the particle size distribution range that impurities in the dirty working solution records, and the pressure size in the tank inner chamber debugs to determine under certain micropore size basis by experiment.
In the actual filtration, the filtering accuracy of this filter core 5 can be selected according to the impurity particle size of the dirty working solution 7 that is filtered.In addition, the upper surface of this filter core fixed head 4 is provided with the fluid pipeline 3 that is communicated with the filter core inner chamber and the tank body outside, and tank body 1 outside is provided with the input duct 2 that feeds tank inner chamber.
The concrete filter method of the filter of the utility model said structure is as shown in Figure 2: dirty working solution 7 enters tank body 1 inner chamber from input duct 2, adsorbed film 9 on filter core 5 outer surfaces of tank body 1 inside and the micropore 8 on the filter core 5, flow out from filter core fixed head 4 and fluid pipeline 3 again, reach the accurate clarification filtration effect of dirty working solution 7 liquid.Wherein on the filter core 5 aperture of micropore 8 greater than being filtered particulate 6(suspension states of matter) particle diameter; Adsorbed film 9 is by being filtered particulate 6 is adsorbed on filter core 5 under tank body 1 inner certain pressure condition surface in the dirty working solution 7, and micropore crack with holes shape covered, make adsorbed film 9 can stop suspension particulate afterwards to continue to pass through effectively, but liquid can continue to pass through.
Embodiment: water base working solution is often used in the line cutting, its suspension diameter of particle is usually at 0.1-0.7 μ m after testing, and selecting filtering accuracy for use is that the filter core 5 of 1-2 μ m filters, through using for a long time, working solution after the filtration detects less than the impurity more than the 0.1 μ m, and filter effect is fine.
By this filter of the visible the utility model of embodiment and based on the filter method of this kind filter good filtration effect at line cutting processing working solution, the plugging rate that filter core takes place is little, and it is less to filter cost filtering scheme relatively in the past.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
