Abstract

The utility model relates to a vacuum oil-filtering machine, which is provided with a mechanical filtering device, a heater, a vacuum tank, a vacuum pump, an oil drain pump, a pipeline, a valve, a control system, etc. The utility model is characterized in that an inflation pipe is arranged below an oil storage layer in the vacuum tank (2); one or a plurality of small holes are bored on the inflation pipe; an air inlet of the inflation pipe is fixed to the outside of the vacuum tank, and is provided with an air input regulator (1). One or more layers of sieve layers or bore plate layers can be arranged on the space position above the vacuum tank in order to improve separation effect. Consequently, oil flowing down can be distributed uniformly, or foam in the air moving upwards can be eliminated. The machine has the advantages of simple structure and effectiveness, and can realize the high efficiency and low energy consumption of oil and water separation.

Description

Vacuum oil-filter

Vacuum oil-filter of the present utility model belongs to the industrial separation apparatus field.

In the prior art, the vacuum oil-filter that is used for oily water separation has had bigger development, but still has the not high shortcoming of efficient.For example, Chinese patent ZL97226341.1 discloses a kind of oil filter water-and-oil separator, and the tank body of this separator is a vertical structure, and there is the oily water separation frame its middle and lower part, it forms perforation on the oily water separation sheet by at least five oily water separation sheet and linings with fold.The vacuum oil-filter of this water-and-oil separator comparison prior art improves to some extent, but it still exists complex structure, inefficient shortcoming.

The purpose of this utility model is, provides a kind of simple in structure, and effective vacuum oil-filter to realize the high-level efficiency and the low consumption of oily water separation, reaches good economic benefit.

For achieving the above object, vacuum oil-filter of the present utility model, include mechanical screening device, well heater, vacuum tank, vacuum pump, oil drain pump, pipeline, valve and Controlling System etc., it is characterized in that, be provided with gas-filled valve in vacuum tank inner product oil reservoir bottom, be drilled with one or several apertures on the gas-filled valve, the inlet mouth of gas-filled valve is fixed on the outside of vacuum tank and is provided with the air input setter; For improving separating effect, also 1 to several layers screen layer or orifice layer can be set on vacuum tank internal upper part locus, so that make the fluid uniform distribution that flows down or eliminate foam in the up gas.For the two-stage vacuum oil filter that is provided with two vacuum tanks, can two vacuum tank inner product oil reservoir bottoms gas-filled valve be set respectively, be drilled with one or several apertures on the gas-filled valve, the inlet mouth of gas-filled valve is separately fixed at the outside of two vacuum tanks, and be respectively arranged with the air input setter, also 1 to several layers screen layer or orifice layer can be set respectively on its vacuum tank internal upper part locus.In order to improve the exhaust capacity of vacuum-pumping system, improve the effect of oily water separation, can on the pipeline between vacuum pump inlet mouth and the vacuum tank bleeding point, condenser be set, select for use the cooling water car case to make condenser, be provided with in the windward side of condenser and use fan driven by motor.Force cooler condenser by the fan blowing, can obtain good cooling performance.

Vacuum oil-filter according to the such scheme manufacturing, because gas-filled valve is set in vacuum tank, when its work, in vacuum tank, charge into the air of proper amt, under vacuum state, volume of air expands rapidly, and the air after the expansion upwards stirs from the oil reservoir bottom, make the inner liquid-gas interface that moves up fast that forms of fluid, greatly quickened the speed of water content in oil evaporation.The fan that is provided with on vacuum-pumping system is forced the refrigerative condenser, and the water vapor condensation Cheng Shui that extracts out in vacuum tank, this has just increased the effect that vacuum pump is bled, and has also just strengthened the effect of oily water separation.Below, introduce the utility model embodiment in conjunction with the accompanying drawings.

Fig. 1 is the vacuum tank synoptic diagram of the utility model vacuum oil-filter.

Fig. 2 is that the condenser structure and the position of the utility model vacuum oil-filter concerns synoptic diagram.

Shown in Figure 1, be provided with gas-filled valve 7 in vacuum tank 2 inner product liquid layers 6 bottoms, be drilled with one or several apertures on the gas-filled valve, the inlet mouth of gas-filled valve 7 is fixed on the outside of vacuum tank 2 and is provided with air input setter 1; Orifice layer 5 is located at vacuum tank 2 internal upper part locus, and 3 is the vacuum tank bleeding point, and 4 is oil-in, and 8 is oil outlet.

Shown in Figure 2, the inlet mouth 14 of condenser 13 is communicated with the bleeding point 3 of vacuum tank 2, and air outlet 15 is communicated with vacuum pump, is provided with condensed water discharge outlet 16 in condenser 13 bottoms, and the fan 12 of translator 11 is fixed on the windward side of condenser 13.

When the vacuum oil filter is worked, vacuum pump vacuumizes to vacuum tank 2 by condenser 13, fluid after pending being heated enters vacuum tank 2 from oil-in 4, after splashing into oily foam on the orifice layer 5, fall into jar bottom and form hydrops 6, open air input setter 1, air enters the bottom of oil reservoir 6 from gas-filled valve 7, under vacuum state, the volume that enters air is swollen rapidly, bubbling rises in oil reservoir, the liquid-gas interface that fluid is formed move up fast, isolated water vapour rises with air-flow in the oil, through bleeding point 3,14, enter condensation 13, forced refrigerative steam coagulation Cheng Shuike to discharge from discharge outlet 16 by fan 12, the gas that does not coagulate is then discharged by vacuum pump by air outlet 15.The fluid that has removed moisture content is discharged by oil drain pump from the oil outlet 8 of vacuum tank 2 bottoms.
