The specific embodiment
The anti-chuck floating roof tank of a kind of available testing seawater pressure of the present invention, comprise tank body 1, the interior installation floating plate 2 of tank body 1, some pillars 3 are installed on floating plate 2, tank body 1 inside bottom surface is installed several tank body sacrificial block 4, several floating plate sacrificial block 5 are installed in floating plate 2 bottom surfaces, piezometric tube 6 is installed on floating plate 2, piezometric tube 6 is bodys of vertically installing on floating plate 2, piezometric tube 6 top closure, piezometric tube 6 bottoms communicate with floating plate 2 downsides, the interior installation pressure measurement of piezometric tube 6 piston 7, piezometric tube 6 madial walls are installed touch switch 8, touch switch 8 is connected with controller 17 by data line, at least 3 sleeve pipes 24 are set on floating plate 2, each sleeve pipe 24 is uniformly distributed along floating plate 2 borders, non-self-locking hydraulic cylinder 9 is installed on sleeve pipe 24 tops, each non-self-locking hydraulic cylinder 9 is all connected with controller 17 by data line, the push rod 10 of non-self-locking hydraulic cylinder 9 is positioned at the tube chamber 11 of sleeve pipe 24, the interior dividing plate 12 that arranges of tube chamber 11, on dividing plate 12, offer through hole 13, the interior installation guide rod 14 of through hole 13, guide rod 14 one end are connected with the push rod 10 of non-self-locking hydraulic cylinder 9, guide rod 14 other ends contact with the cylinder body of bounce cylinder 15, the piston rod 16 of bounce cylinder 15 is connected with dividing plate 12, feet 25 is installed in bounce cylinder 15 bottoms, when bounce cylinder 15 is compressed to end position, floating plate 2 bottom surfaces are less than or equal to floating plate 2 bottom surfaces to the distance of pillar 3 lower ends to the distance of feet 25 bottom surfaces, during bounce cylinder 15 complete diastole, floating plate 2 bottom surfaces are greater than floating plate 2 bottom surfaces to the distance of pillar 3 lower ends to the distance of feet 25 bottom surfaces, tank body 1 sidewall arranges input duct 21.Because the conductivity water temperature and depth of tank body sacrificial block 4 and floating plate sacrificial block 5 is all higher than the alloy-steel plate of tank body 1 and floating plate 2, therefore the electrochemical reaction that the chloride ion in the interior residual seawater of tank body 1 produces preferentially occurs at sacrificial block place, thereby play, prevents that tank body 1 and floating plate 2 places are subject to the effect of marine corrosion.Storage tank is oil-filled while enabling, after the tank body 1 of floating plate 2 belows is full of, floating plate 2 should together float with liquid level, if now floating plate 2 and tank body 1 sidewall adhesion, can cause floating plate 2 to block in tank body 1, cannot rise, as processed not in time, can cause chuck accident, cause equipment impaired, when floating plate 2 blocks, floating plate 2 bottom tank body 1 internal pressures rise, after pressure measurement piston 7 pressurizeds in piezometric tube 6, rise, by the air compressing between pressure measurement piston 7 and piezometric tube 6 tops, when floating plate 2 bottom tank body 1 internal pressures are depressed into the height of touch switch 8 by pressure measurement piston 7, pressure measurement piston 7 contacts with touch switch 8, touch switch 8 is opened, to controller 17, send energizing signal, controller 17 receives after energizing signal, to each non-self-locking hydraulic cylinder 9, send actuation signal, the push rod 10 of non-self-locking hydraulic cylinder 9 is moved down, by guide rod 14, the cylinder body of bounce cylinder 15 and feet 25 are by floating plate 2 jack-up one segment distance upwards, make floating plate 2 separated with tank body 1, solve in time chuck problem.During storage tank oil extraction, floating plate 2 declines with liquid level, and in floating plate 2 decline processes, feet 25 first contacts with at the bottom of tank, gas in bounce cylinder 15 is compressed, floating plate 2 is declined and plays buffer action, and the Speed Reduction when making pillar 3 lower ends and contacting at the bottom of tank, prevents that pillar 3 from will push up and wear at the bottom of tank.
The present invention participates in the area of reaction in order to expand tank body sacrificial block 4, can be at the interior crossbeam 18 running through at two ends that arranges of tank body sacrificial block 4, and a support 19 is respectively installed at crossbeam 18 two ends, and support 19 is connected with tank body 1 inside bottom surface.This structure can make tank body sacrificial block 4 bottom surfaces also participate in electrochemical reaction, and the area that makes tank body sacrificial block 4 participate in reaction is increased, and is conducive to improve the reaction efficiency of tank body sacrificial block 4 and chloride ion.
The present invention, can be at floating plate sacrificial block 5 one end mounting suspensions 20 for the ease of fixing floating plate sacrificial block 5, and suspension bracket 20 is connected with floating plate 2 bottom surfaces.Because floating plate sacrificial block 5 self is difficult to and floating plate 2 welding, therefore can adopt said structure, during installation, by suspension bracket 20 and floating plate 2 weld togethers, realize fixing floating plate sacrificial block 5.
The present invention is in the situation that excessive can the stopping in time of tank body 1 internal pressure of floating plate 2 bottoms, to oil-filled in storage tank, can be installed into liquid pump 22 in input duct 21, and liquid feeding pump 22 is connected with controller 17 by data line.When floating plate 2 blocks completely; in the time of cannot be separated with tank body 1, pressure measurement piston 7 keeps the state contacting with touch switch 8 always, and this Time Controller 17 can send shutdown signal to liquid feeding pump 22; stop to the interior continuation pump oil of tank body 1, the equipment that prevents damages because pressure is excessive.
Described tank body sacrificial block 4 of the present invention and floating plate sacrificial block 5 are all that aluminium-zinc-indium-cadmium is associated gold anode sacrificial block.The reactivity worth of above-mentioned sacrificial block in seawater, higher than the sacrificial block of other type, is more suitable for using in briny environment.
Storage tank of the present invention is not during oil-filled enabling, the negative pressure producing between pressure measurement piston 7 and piezometric tube 6 tops and pressure measurement piston 7 dead-weight balanced, guarantee that pressure measurement piston 7 is in piezometric tube 6, can not come off from piezometric tube 6 lower ends, but use for a long time or idle after along with the sealing effectiveness reduction between pressure measurement piston 7 and piezometric tube 6, pressure measurement piston 7 can be destroyed with the negative pressure at piezometric tube 6 tops, causes pressure measurement piston 7 to move down until come off from piezometric tube 6 lower ends.The present invention comes off from piezometric tube 6 lower ends for fear of pressure measurement piston 7, can baffle ring 23 be installed in piezometric tube 6 inner sides, lower end.This structure be conducive to guarantee the present invention long-term use or idle after still can there is the function of automatic eliminating chuck fault.
