Abstract

An oil filter separator belongs to the technical field of filter units and is characterized in that: a cylinder body is internally provided with a primary filter core and a secondary filter core, which divide the inner chamber of the cylinder body into three mutually separated sub chambers, i.e. a feeding chamber, a discharging chamber and a transition chamber, the lower end of the cylinder body is provided with three openings which are respectively a feeding hole communicated with the feeding chamber, a discharge hole communicated with the discharging chamber and a drain outlet communicated with the transition chamber, the lower end of the primary filter core is communicated with the feeding chamber, and the lower end of the secondary filter core is communicated with the discharging chamber. The surfaces of the primary filter core and the secondary filter core are shaped like a corrugated pipe. The oil filter separator provided by the utility model combines a primary filter unit and a secondary filter unit in the prior art into one, so that equipment is simple, the structure is compact and the occupied space is saved, in addition, since the surfaces of the primary filter core and the secondary filter core are shaped like a corrugated pipe, the area of the filtering surface is greatly increased, the filtering effect is good, the blockage can be effectively avoided, the times of replacing the filter cores and shut-down maintenance are reduced and the daily maintenance cost is low.

Description

A kind of oil plant filter separator

Technical field

The utility model relates to the filter technical field, particularly relates to a kind of technology of oil-water filtration separator of petrochemical industry.

Background technology

The oil plant filter separator is widely used in metallurgy, chemical industry, oil, food, mining, power domain.Such as industrial waste oil, the circulation oil filtration is a kind of advanced person, efficient and easy-operating filter.

In the oil refining industry, water-oil separating is an important indicator, uses moisture content content overproof with gasoline, vehicle with oil as aviation, will influence normal the use, even cause serious disaster.In order to ensure filtering accuracy, usually adopt the double-filtration separator, the one-level filter is coarse filtration, moisture content in most of oil plant is intercepted with impurity separate, the secondary filter element device is smart the filtration, further impurity such as minute water molecule in the oil plant of one-level filter outflow is separated and removes.And the filter core of existing oil plant filter separator all is straight tube-like, and its filtering surface area is less, so filter effect is relatively poor, results in blockage easily, thereby increases the more number of times of renew cartridge, shut-down (breakdown) mainteance, and its life cycle is shorter, the maintenance cost height.

The utility model content

At the defective that exists in the above-mentioned prior art, technical problem to be solved in the utility model provides and a kind of one-level filter and secondary filter element device is united two into one, and the filtering surface area is big, good filtration effect, the oil plant filter separator that operating cost is low.

In order to solve the problems of the technologies described above, a kind of oil plant filter separator provided by the utility model, comprise cylindrical shell, with the filter core that places in the described cylindrical shell, it is characterized in that: described cylindrical shell is built-in with one-level filter core and secondary filter core, and the inner chamber of described cylindrical shell is separated into three sub-chambeies that cut off mutually, is respectively feed cavity, discharging chamber and adapter cavity, the lower end of cylindrical shell is provided with three openings, is respectively charging aperture, discharging opening that is communicated with the discharging chamber that is communicated with feed cavity and the sewage draining exit that is communicated with adapter cavity; The lower end of described one-level filter core is communicated with feed cavity, and the lower end of described secondary filter core is communicated with the discharging chamber.

Described one-level filter core and secondary cartridge surface are corrugated tube shape.

The oil plant filter separator that the utility model provides, one-level filter in the prior art and secondary filter element device are united two into one, simple, the compact conformation of equipment takes up an area of and economizes, and one-level filter core and secondary cartridge surface are and are corrugated tube shape, filtering surface area increases greatly, good filtration effect can effectively be avoided stopping up, and life cycle is long, reduce filtering core and change the number of times of shut-down (breakdown) mainteance, the regular maintenance cost is low.

Description of drawings

Below in conjunction with description of drawings embodiment of the present utility model is further described.

Fig. 1 is the sectional structure schematic diagram of the utility model oil plant filter separator.

The specific embodiment

As shown in Figure 1, a kind of oil plant filter separator provided by the utility model, comprise cylindrical shell 1, with the filter core that places in the described cylindrical shell 1, it is characterized in that: one-level filter core 2 that described cylindrical shell 1 is built-in with and secondary filter core 3, the inner chamber of described cylindrical shell 1 is separated into three sub-chambeies that cut off mutually, be respectively feed cavity 4, discharging chamber 5 and adapter cavity 6, the lower end of cylindrical shell 1 is provided with three openings, is respectively charging aperture 41, discharging opening 51 that is communicated with discharging chamber 5 that is communicated with feed cavity 4 and the sewage draining exit 61 that is communicated with adapter cavity 6; Described feed cavity 4 and discharging chamber 5 all are positioned at cylindrical shell 1 bottom; The lower end of described one-level filter core 2 is communicated with feed cavity 4, and the lower end of described secondary filter core 3 is communicated with discharging chamber 5.

Described one-level filter core 2 and secondary filter core 3 surfaces are corrugated tube shape.

Among the utility model embodiment, the bottom of described cylindrical shell 1 is provided with support 7, and cylindrical shell 1 is fixedlyed connected with ground, and cylindrical shell 1 top is provided with adpting flange 8.

The utility model embodiment is before filtered stock, sewage draining exit 61 with cylindrical shell 1 lower end seals earlier, then oil plant to be filtered is continued to introduce feed cavity 4 from charging aperture 41, rising along with feed cavity 4 internal pressures, oil plant in the feed cavity 4 enters from the lower end of one-level filter core 2, side face from one-level filter core 2 after one-level filter core 2 filters continues to ooze out in the adapter cavity 6, thereby most moisture content and impurity in the oil plant are intercepted in one-level filter core 2, when the oil plant after one-level is filtered continues to flow into adapter cavity 6, adapter cavity 6 internal pressures also increase, oil plant in the adapter cavity 6 after one-level is filtered enters secondary filter core 3 from the side face of secondary filter core 3 under pressure, flow into discharging chamber 5 from the lower end of secondary filter core 3, thereby most residual moisture content and residual impurity in the oil plant after the one-level filtration are intercepted in adapter cavity 6, thereby guarantee the filtering accuracy of oil plant in the secondary filter core 3, the oil plant in the discharging chamber 5 behind cascade filtration is discharged cylindrical shell by the discharging opening 51 that is communicated with discharging chamber 5.

Open the sewage draining exit 61 of cylindrical shell 1 lower end after oil plant filters and finishes, the dirt in the cylindrical shell is discharged.

The utility model embodiment is applicable to and filters kerosene, gas and oil, naphtha and crude oil, also can be used for filtering other oil plant.
