Abstract

The utility model relates to an emergency water discharging device used for a large floating-roof oil tank, mainly composed of a filtering water collecting cover (1), a sealing system (2) and a water sealing tank (3). The utility model is a novel emergency water discharging device which effectively solves the defects that the storing liquid is flowed back, water closing loses water and needs often add water, condensation oil and wax blocks are fallen off and plug a drainage hole, etc.

Description

Float-type emergency water discharging device for floating oil tank

The utility model is used for the urgent draining of large floating roof oil tank, is the indispensable safety attachment of floater.

Because the overload ponding that central drain lost efficacy or the drainage ability deficiency is caused causes floating grave accident of pushing up sinking, on the large floating roof oil tank urgent freeing arrangement must be installed in order to prevent large floating roof oil tank.Up to the present, the urgent freeing arrangement structure of installing on all floaters in the world only is drain hose and water sealed tank of a band filter screen, and dehydration need often add water because evaporation and liquid storage flow in its water seal, and this causes a lot of troubles to production control.Simultaneously, this device does not prevent the function that liquid storage flows backwards again, thus in pipe dehydration and pontoon jam and cause easily under the bevelled situation that liquid storage flows back on the single-deck, thereby may cause major accident such as shipwreck.

The purpose of this utility model is to provide a kind of both can get rid of overload ponding effectively, can prevent the urgent freeing arrangement that liquid storage flows backwards again, can change parts when not stopping production, and need not get angry, simple in structure, rationally, reliable.

The utility model is made up of filtration catchment covers, sealing system, water sealed tank three parts, filters the upper end that catchment covers is installed in drain hose, and sealing system is installed in the inside of drain hose, and water sealed tank is connected with the bottom of drain hose.

Said water sealed tank is to have connected round-meshed half cover plate on two in the upper end of a circular channels, adds baffle plate on the top of water sealed tank; Said filtration catchment covers is a filtration water collecting structure that is welded with filter screen and steelframe; Said sealing system is a dish (or spherical) float of packing in guide cylinder, and is screwed on blind flange, and embeds the seal ring that flange covers.

The utility model has solved the liquid storage refluence, and rational in infrastructure, simple, reliable, water seal is tight, smoothly draining.

Fig. 1 is an overall construction drawing of the present utility model.

Fig. 2 is for filtering the constructional drawing of catchment covers.

Fig. 3 is the constructional drawing of sealing system.

Fig. 4 is the constructional drawing of water sealed tank.

Wherein: 1 filters catchment covers 9 connecting panels 2 sealing systems 10 baffle plates 3 water sealed tanks 11 drain hoses 4 base plates 12 flanges 5 side plates 13 blind flanges 6 stay bearing plates 14 guide cylinders 7 half cover plates 15 floats 8 flanged plates 16 seal rings

The utility model mainly is made up of filtration catchment covers 1, sealing system 2, water sealed tank 3 three parts, filtration catchment covers 1 is installed in the upper end of drain hose 11, sealing system 2 is installed in the inside of drain hose 11, water sealed tank 3 links to each other with the bottom of drain hose 11, the filter screen that filters in the catchment covers 1 has changed a filtration water collecting structure that is welded with filter screen and steelframe into, it can be gathered rainwater, replenish the water seal dehydration, between filtration catchment covers 1 and drain hose 11, adopted the flange connection, and upper flange has been connected back seal system 2.Sealing system 2 is mainly by guide cylinder 14, float 15 and seal ring 16 are formed, float 15 is contained in the guide cylinder 14, atmosphere and water seal are separated, to prevent the evaporation of water part, thereby having solved the water seal that causes because of dehydration lost efficacy, liquid storage rocks in jar, liquid level rises, and float 15 just can be tight with seal ring 16 sealings that are embedded on the blind flange 13, and prevent that effectively liquid storage from flowing back on the floating top, upward ponding is more when floating top, when needing urgent draining, rainwater just can be depressed float 15 by filtering catchment covers 1, by drain hose 11 water is entered in the jar, two round-meshed half cover plates 7 have been connected on the top of water sealed tank 3 circular channels, add plate washer 10 on the top of water sealed tank 3, not only can prevent with fixed attention the oil clot obstruction drain gutter that comes off, can also prevent effectively that oil product from flowing back on the single-deck, the assurance draining is unimpeded, and is stable.
