Description
Technical field
The utility model belongs to flow instrument protective device technical field, is specifically related to a kind of online blowdown filter of cooling down.
Background technology
The filter of cooling down is one of auxiliary device of flowmeter.Product oil flows into from the filter inlet of cooling down, and removes solid impurity by the screen pack that filter is built-in, and gas rises to filter top, when accumulating to certain gas pressure, by the air valve exhaust, reaches liquid, solid, purpose that gas separates.Therefore the filter of cooling down has the advantages such as service life that guarantee the flowmeter measuring accuracy and prolong flowmeter.
But cool down filter time one of tradition is long, and the impurity in the net tube easily stops up filter screen, causes the flow instrument cisco unity malfunction, even produces and be forced to stop.After filter screen stopped up, the filter of cooling down must integral body be taken apart, with hand tear, means such as baked wheaten cake remove dirt, blowdown is cleaned very inconvenient.So that uses at present cools down filter at set intervals, must breaks in production termination of pumping maintenance, remove the inner solid sundries of piling up of filter screen and change filter screen, not only screen pack is short service life, delays production, and bothersome, labour intensity is big.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple to operate, filter of cooling down of the online blowdown of breaks in production not.
For solving the problems of the technologies described above, the technical scheme that adopts is: the online blowdown filter of cooling down, comprise handwheel, lid, housing, place the filtering net cylinder and the ball float of described housing inner chamber, described ball float is by connecting rod and described lid, and the valve of cooling down is connected, it is characterized in that: in the described housing, upper mounted plate is fixedlyed connected by strut with bottom plate, be equipped with filtering net cylinder between described upper mounted plate and the bottom plate, described filtering net cylinder is built-in with scraper plate, one side of described scraper plate and the medial surface of described filtering net cylinder join, opposite side is fixedlyed connected with lower shaft by supporting arm, and can be with described lower shaft rotation, described housing inner chamber below is equipped with dirt storage room and blowoff valve.
Described supporting arm is an inside and outside sleeve formula syndeton, and sleeve is built-in with the scraper spring.
Between described upper mounted plate and the bottom plate, the outside of filter inlet end, filtering net cylinder laterally is equipped with U font deflector, and the bottom of U word is towards filter inlet, U word opening edge and inner walls are tangent to be welded to connect, and upper and lower both sides are connected with bottom plate with upper mounted plate respectively.
Handwheel is fixedlyed connected with last axle, and lower shaft places the axle center of described filtering net cylinder, described axle and the concavo-convex chimeric joggle of lower shaft gone up.
The beneficial effects of the utility model are: separate fully at original liquid, the gas of making of filter that keeps cooling down, guarantee that blowdown can onlinely be finished on the basis of flowmeter measuring accuracy advantage.Attached to the foreign material on the filtering net cylinder inwall, strike off and drop to dust storage cabin by scraper plate, directly discharge through blowoff valve. avoided shutting down and taken cleaning apart, used more convenient.The utility model row simple to operate, easy.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is scraper plate, supporting arm, following Axile connection structure schematic diagram.
Among the figure, the 1-handwheel; The 2-lid; The 3-housing; The 4-filtering net cylinder; The 5-scraper plate; The 6-lower shaft; The 7-bottom plate; The 8-dust storage cabin; The 9-valve of cooling down; The 10-connecting rod; The 11-ball float; The last axle of 12-; The 13-upper mounted plate; The 14-deflector; 15-connects strut; The 16-blowoff valve; 17-scraper spring; The 18-supporting arm.
Specific implementation method
Fig. 1 is a structural representation of the present utility model, as seen from the figure, the online blowdown filter of cooling down, comprise handwheel 1, lid 2, housing 3, place the filtering net cylinder 4 and the ball float 11 of described housing 3 inner chambers, described ball float 11 is by connecting rod 10 and described lid 2, and the valve 9 of cooling down is connected, it is characterized in that: in the described housing 3, upper mounted plate 13 is fixedly connected by being connected strut 15 with bottom plate 7, be equipped with filtering net cylinder 4 between described upper mounted plate 13 and the bottom plate 7, described filtering net cylinder 4 is built-in with scraper plate 5, one side of described scraper plate 5 and the medial surface of described filtering net cylinder 4 join, opposite side is fixedlyed connected with lower shaft 6 by supporting arm 18, and can be with described lower shaft 6 rotations, described housing 3 inner chambers below is equipped with dirt storage room 8 and blowoff valve 16.
Handwheel 1 is fixedlyed connected with last axle 12, and lower shaft 6 places the axle center of described filtering net cylinder 4, described axle 12 and the lower shaft 6 concavo-convex chimeric joggles gone up.
Between described upper mounted plate 13 and the bottom plate 7, the outside of filter inlet end, filtering net cylinder 4, laterally be equipped with U font deflector (14), the bottom of U word is towards filter inlet, U word opening edge and housing 3 inwalls are welded to connect, and upper and lower both sides are connected with bottom plate 7 with upper mounted plate 13 respectively.
Described ball float 11 is welded to connect with connecting rod 10, and connecting rod 10 is fixedly connected with upper cover plate and be connected with the valve 9 of cooling down.
When filter work is cooled down in online blowdown, liquid vapour mixture is through import inflow filter inner chamber, under the effect of deflector 14, shunt to both sides, through hole through upper mounted plate 13 flows into filtering net cylinder 4, filter the back and flow out from filter outlet, the filter rear impurity is attached to netting on tube 4 inwalls or attaching on scraper plate 5.Import and export that there is differential pressure at two ends or need regularly remove contamination the time when filter, clockwise rotate handwheel 1 and drive and go up axle 12 and lower shaft 6, make scraper plate 5 strike off foreign material, enter dust storage cabin 8 and gather attached to filtering net cylinder 4 inwalls.Repeatedly clockwise rotate handwheel 1, when the filter two ends still have pressure reduction, then need open blowoff valve 16, make the foreign material discharge filter in the dust storage cabin 8, close blowoff valve 16 after a while, finish online blowdown process.
After liquid entered the filter inner chamber of cooling down, contained gas rose to filter housings top in the liquid, formed the gas compartment, along with the increase of gas flow, the gas compartment constantly enlarges, and liquid level constantly descends, ball float 11 descends along with the decline of liquid level, and drivening rod 10 is opened the valve 9 valve exhausts of cooling down.Along with the discharge of gas, liquid level rises rapidly, and ball float 11 is also along with rising, and drivening rod 10, closes the venting ball valve of the valve 9 of cooling down, and makes the liquid can not be excessive.When gas accumulates to again to a certain degree, air bleeding valve is opened exhaust again, and the process of cooling down is finished in so periodic duty.Like this, the cool down medium of filter of flowing through has just reached the purpose that oil, gas, solid three separate, and is clean and does not contain the liquid of gas from what filter was discharged.
Whole process is all online to be finished, and need not termination of pumping, does not influence production.
