Abstract

The invention discloses a double-cylinder filter comprising two same filter cylinders and an oil inlet pipe, an oil outlet pipe and a dirt discharge pipe connecting the two filter cylinders. An oil inlet, an oil outlet and a dirt discharge port are respectively arranged at the middle parts of the oil inlet pipe, the oil outlet pipe and the dirt discharge pipe. Inlet valves, outlet valves and discharge valves are respectively arranged on the pipelines on the two sides of the oil inlet, the oil outlet and the dirt discharge port. Wedged V-shaped filtering meshes are arranged in the filtering cylinders. Anti-abrasion decontamination devices and cylinders are arranged at the tops of the filtering cylinders. The anti-abrasion decontamination devices move up and down under the driving of the cylinders. The double-cylinder filter provided by the invention has the advantages of simple and reliable structure, convenient application, stable performance, and high decontamination efficiency. With the double-cylinder filter, filtering and washing are integrated. Filtering cores can be cleaned or replaced while the machine is not turned off, such that main machine normal working can be ensured.

Description

A kind of double-drum filter

Technical field

The present invention relates to art of filters, particularly relate to a kind of double-drum filter.

Background technology

In petroleum chemical industry, crude oil and catalyst react and can produce the impurity of high viscosity, high rigidity in process.Need with filter plant by these impurity filterings, the follow-up use of guarantee is unaffected.Double-drum filter; in non-stop-machine situation capable of washing or more renew cartridge to ensure main frame normal and continuous operation; therefore application is commercially more and more extensive; but the impurity of working as filter interior is saved bit by bit and to a certain degree and is not cleaned in time; the filter effect of filter will be affected, even can damage filter.So when designing filter, how effectively removing the impurity saved bit by bit just becomes the problem that must consider.

Mainly in filter adopt V-type filter core abroad at present, recoiled by external liquid during removal of contamination, make its pressure higher than filtered inlet pressure, thus eliminating particle impurity.Second method adopts different liquids and filter core surface impurity to carry out soaking again with stoste recoil eliminating particle impurity.There is following problem in said method: time one, with external liquid recoil removal of contamination, has external liquid in the filter and remain, pollute filtrate; Two, rinse with external liquid, improve production cost; Three, again with stoste recoil after impurity being soaked, can take a long time, and the stoste after cleaning cannot continue to use; Four, adopt V-type filter core, normally liquid enters from slot out from uncovered, and filter core inner surface can be made like this to deposit too many impurity, even if from outlet recoil, can not clean up well.

Summary of the invention

In order to solve the problems of the technologies described above, the invention provides a kind of double-drum filter, conveniently can remove deposition impurity on the filter.

The technical solution used in the present invention is: a kind of double-drum filter, comprise two identical cartridge filters and the in-line being connected described two cartridge filters, outlet line and blowoff line, at described in-line, oil-in is respectively equipped with in the middle of outlet line and blowoff line, oil-out and sewage draining exit, at described oil-in, the pipeline of the left and right sides of oil-out and sewage draining exit is respectively equipped with inlet valve, outlet valve and blowoff valve, it is characterized in that, wedge shape V-type screen pack is also provided with in described cartridge filter, cartridge filter top is provided with antifriction dirt separator and cylinder, described antifriction dirt separator is driven by described cylinder and moves up and down.

Further, described wedge shape V-type screen pack becomes the V-type filter core of straight-tube shape to form by vertical array.

Further, described V-type filter core outwards uncovered, slot is inside.

Advantage of the present invention is: this double-drum filter is simple and reliable for structure, easy to use, stable performance, and scrubbing efficiency is high.Drive antifriction dirt separator to be close to screen pack by cylinder to move up and down, effective removal of contamination; Liquid from inside to outside, namely enters from V-type filter core slot, and this design makes impurity major part be deposited on slot, can be removed by antifriction dirt separator; Double tube design, in non-stop-machine situation namely capable of washing or more renew cartridge to ensure that main frame normally works.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is further described, but protection scope of the present invention is not limited thereto.

As shown in Figure 1, a kind of double-drum filter, comprise two identical cartridge filters 1 and the in-line 5 being connected described two cartridge filters 1, outlet line 6 and blowoff line 7, at described in-line 5, oil-in 8 is respectively equipped with in the middle of outlet line 6 and blowoff line 7, oil-out 9 and sewage draining exit 10, at described oil-in 8, the pipeline of the left and right sides of oil-out 9 and sewage draining exit 10 is respectively equipped with inlet valve 11, outlet valve 12 and blowoff valve 14, the wedge shape V-type screen pack 4 becoming straight-tube shape to form by V-type filter core vertical array is also provided with in described cartridge filter 1, cartridge filter 1 top is provided with antifriction dirt separator 3 and cylinder 2, when screen pack depositing high viscosity impurity, drive antifriction dirt separator 3 to be close to screen pack by cylinder 2 to move up and down, effective removal of contamination.

Described V-type filter core outwards uncovered, slot is inside, and liquid from inside to outside, namely enters from slot, filtering and impurity removing, this design makes impurity major part be deposited on slot, can be removed by antifriction dirt separator 3, and original equipment outlet pressure filtered fluid also can be utilized to carry out backwash except lower sump oil and impurity by filtrate outlet 13 simultaneously, be discharged to slop tank or return original device recycling, uncovered to slot recoil from V-type filter core, slot place pressure is larger, cleans cleaner.

As shown in Figure 2, cartridge filter sidewall is fixed muscle 16 pairs of gratings 15 by ring-type and is reinforced.

The filtration cleaning process of this double-drum filter is as follows: during filtration, by the both sides inlet valve 11 on in-line 5 and outlet line 6, outlet valve 12 is opened, the blowoff valve 14 of blowoff line 7 cuts out, need filter liquide (such as impure crude oil) to be entered on the upside of cartridge filter 1 by in-line 5 from oil-in 8, enter outlet line 6 by filtrate outlet 13 after then being filtered by wedge shape V-type screen pack 4 and discharge from oil-out 9.Along with time increase V-type cartridge surface impurity can be more poly-more, when Pressure Drop reaches setting value, filter will automatically (manually) start working and carry out cleaning depolluting processes, first start decontamination apparatus, close inlet valve 11, open blowoff valve 14, then antifriction dirt separator 3 removes sump oil and impurity on screen pack inwall from top to bottom by interior, adopt in automatic pollutant removal process and carry out backwash from flow liquid by filtrate outlet 13, remove lower sump oil and impurity, be discharged to slop tank or return original device recycling.

This double-drum filter work time can close side on each pipeline valve adopt monotubular filter, change another cartridge filter time to be cleaned and work on, do not affect whole technological process continue carry out.In addition, this filter integrates filtration and cleans, and filter core is without the need to soaking and need not recoiling by external liquid, time saving and energy saving, simple to operate.

Above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, and to not departing from any amendment of spirit and scope of the invention or equivalent replacement, it all should be encompassed in the middle of right of the present invention.
