Description

Oil drop pot strainer is unloaded in oil field

Technical field

The utility model relates to a kind of oil field and unloads oil drop pot strainer, particularly relates to the filtration device structure improvement that collection station, oil field online backwashing is removed contamination, belongs to pot strainer technical field.

Background technology

Conventional filter backwash generally adopts by-pass valve control and exterior line medium, and carry out backwash in the mode contrary with filtration to filter core, rinsed by the sticky impurity amassed in element wall, whole filter-core back-flushing cleaning control system structure comparatively bothers.Especially when oil field waste oil collection station uses, containing under the operating mode of the larger particles impurity such as rubber, cotton yarn, greasy filth in impurity, be difficult to accomplish online backwashing, blowdown, filter core easily blocks, and pump seizure can be caused even to scrap, often taking-up cleaning or more renew cartridge as can not get cleaning or replacing in time, need termination of pumping breaks in production, not only bothersome effort, labour intensity is large, and delays production.

Summary of the invention

It is simple that the object of utility model is to provide a kind of structure, and easy to operate, own vol is little, and dirt storage room's volume is large, can not termination of pumping, swift to operate, remove contamination, oil field that filth-discharging effect is good unloads oil drop pot strainer.

For achieving the above object, the technical scheme adopted is: oil drop pot strainer is unloaded in a kind of oil field, comprise cylindrical shell, filter core, handwheel of removing contamination, dirt storage room and blowoff valve, it is characterized in that: in described filter core chamber, the upper and lower of central shaft is fixedly connected with the horizontally disposed central point scraping brush holder in cross shape respectively, interval is configured at the wire brush of cross shape end or scraper plate contacts with described filter core medial surface; The upper end of described central shaft is fixedly connected with the handwheel of removing contamination being placed in described cylindrical shell top, and can rotate with the rotation of handwheel of removing contamination;

Be equipped with blowback between described filter core and cylindrical shell and sweep vertical tube, inside described cylindrical shell, the below of filter core is equipped with horizontally disposed blowback and sweeps endless tube; Described blowback is swept vertical tube and blowback and is swept endless tube and sweep air inlet duct respectively with blowback and be connected and communicate; Described blowback sweeps the blow valve port of vertical tube from outside to inside, and described blowback sweeps the blow valve port of endless tube from top to bottom.

The vertical tube quantity six roots of sensation is swept in described blowback, is parallel to each other along the annulus between described cylindrical shell and described filter core and evenly configures.

Good effect of the present utility model is: can effectively remove the oarse-grained impurity such as rubber, cotton yarn, greasy filth by the wire brush, the scraper plate that are fixedly connected with linkage with handwheel of removing contamination; Adopt backwash vertical tube directly to purge filter core outer wall, and sweep the downward blow valve port of endless tube by bottom blowback, impurity is blown into blow-off pipe; Scrape wire brush on brush holder, scraper plate and anti-purging technology and use, remove contamination effective; Be filter or blowdown all without the need to termination of pumping operation, easy to operate.

Detailed description of the invention

Fig. 1 is the utility model structural representation, and Fig. 2 is that the A-A of Fig. 1 is to structural representation.Shown in Fig. 1 and Fig. 2, oil drop pot strainer is unloaded in a kind of oil field, comprise cylindrical shell 11, filter core 10, to remove contamination handwheel 6, dirt storage room 2 and blowoff valve 1, it is characterized in that: in described filter core 10 chamber, the upper and lower of central shaft 4 is fixedly connected with respectively with in horizontally disposed brush holder 15 central point of scraping of cross shape, described brush holder 15 of scraping is in cross shape, interval is configured at the wire brush 13 of cross shape end or scraper plate 14 contacts with described filter core 10 medial surface, the upper end of described central shaft 4 is fixedly connected with the handwheel 6 of removing contamination being placed in described cylindrical shell 11 top, and can rotate with the rotation of handwheel 6 of removing contamination, ,

Be equipped with blowback between described filter core 10 and cylindrical shell 11 and sweep vertical tube 9, inside described cylindrical shell 11, the below of filter core 10 is equipped with horizontally disposed blowback and sweeps endless tube 12; Described blowback is swept vertical tube 9 and blowback and is swept endless tube 12 and sweep into gas port 17 pipeline respectively with blowback and be connected and communicate; Described blowback sweeps the blow valve port of vertical tube 9 from outside to inside, and described blowback sweeps the blow valve port of endless tube 12 from top to bottom.

The vertical tube 9 quantity six roots of sensation is swept in described blowback, is parallel to each other and evenly configures (Fig. 2) along the annulus between described cylindrical shell 11 and described filter core 10.

During use, normal filtration state ,the medium of filtered enters filter core 10 by suction flange 3 through cylindrical shell 11, and under pressure from inside to outside by filter core 10 screen filtration media, the medium after filtration flows out through outlet(discharge) flange 7.Accumulate in impurity on filter core 10 screen cloth wall to remove contamination handwheel 6 through manual rotation, drive in filter core 10 impurity on the stainless steel wire brush 13 scraped on brush holder 15, scraper plate 14 wiper removing screen cloth, to scrape in the contamination precipitation to the dirt storage room of end socket such as rubber, cotton yarn, greasy filth that falls 2, store a certain amount of after discharged from sewage draining exit by blowoff valve 1.

When filter uses a period of time, there is blocking in filter core 10 screen cloth, and medium circulation is smooth, need carry out blowback and sweep, first close the forward and backward valve of import/export flange when blowback is swept to filter, opens blowoff valve 1 and compressed air is swept into gas port 16 from blowback enter.Sweep vertical tube 9 pairs of filter core 10 surrounding ecto-entads by six roots of sensation blowback to purge, rotate handwheel 6 of removing contamination simultaneously and drive in filter core 10 the stainless steel wire brush 13 scraped on brush holder 15, scraper plate 14, wiper removes the impurity on filter core 10 screen cloth inwall, and ensure that the even purging of filter core 10 outer wall, blow the impurity such as rubber, cotton yarn, greasy filth scraped off and sweep endless tube 12 to blowing down to dirt storage room 2 by the blowback above dirt storage room 2 again, discharge from the sewage draining exit of blowoff valve 1, thus the dual purpose of blowdown is swept in the recoil of the wiper filtration blowdown and screen cloth lateral surface that reach the screen cloth inwall of filter core 10.Need not stop cleaning filter cylinder or more renew cartridge in whole on-line filtration process, substantially prolongs the service time of filter, effectively reduce the probability of filter core screen cloth blocking, improve operating efficiency.
