Description
Technical field
The utility model is related to Liquefied Hydrocarbon and LNG cold storage tank, and in particular to the immersed pump of such low-temperature storage tank
Well system.
Background technology
With increase of the world to environmental issue attention degree, Liquefied Hydrocarbon (Liquefied Hydrocarbon) and liquefaction
The consumption of the clean energy resourcies such as natural gas (Liquefied Natural Gas, hereinafter referred to as LNG) is just continuously increased, large-scale liquid
The demand for changing hydrocarbon and LNG cold storage tank also rises therewith.More than this kind of low-temperature storage tank using immersed pump as medium to
Outer mode of movement.The safety and steady operation of immersed pump is ensured, significant to low-temperature storage tank.
Immersed pump is arranged on pump sump bottom, and pump sump bottom is provided with bottom valve, and the elevating control of immersed pump is leaned in the opening and closing of bottom valve：
When immersed pump falls within pump sump bottom, bottom valve is opened by its weight.After bottom valve is opened, its flange entrance generally only has apart from tank bottom
300mm～480mm.This kind of structure is easy in the impurity suction pump in storage tank, so as to cause the damage of immersed pump.
Storage tank may produce some impurity in tank bottom in construction manufacture process, and in storage tank use, these impurity have been difficult
Clear all.Immersed pump is generally not provided with protector at present, therefore during its work, it is easy to by the impurity suction pump in storage tank
In, the damage of itself is caused, and then affects the operation of whole low-temperature storage tank.Therefore design one kind is simple to manufacture, with low cost
Immersed pump protector has realistic meaning.
Utility model content
The purpose of this utility model is to provide a kind of low temperature immersed pump bottom filter.The filter is prevented from
Impurity, and simple structure is sucked when immersed pump runs, it is easy to manufactured, with low cost.
The utility model can be achieved through the following technical solutions：A kind of low temperature immersed pump bottom filter, its feature
It is that filter is cylindrical, including base plate, screen pack, top angle iron frame, flat-beam and bottom angle iron frame, top corner
Eight flat-beams, base plate, top angle iron frame, flat-beam and bottom angle frame is welded between steel frame and bottom angle iron frame
Connected using welding manner between frame, screen pack is wrapped on the outside of top angle iron frame, flat-beam and bottom angle iron frame, is played
Filtration, is connected using sequential welding mode between screen pack and top angle iron frame and bottom angle iron frame, between flat-beam
Connected using intermittent weld mode.
Three outages are set on base plate, and outage is covered with screen pack.
Filter is fixed on inner canister tank bottom by connecting plate and angle cleat, passes through spiral shell between connecting plate and angle cleat
Tether and connect, connecting plate is 4～8 with the quantity of angle cleat.
The utility model is applied to the low-temperature storage tank for containing the medium such as Liquefied Hydrocarbon and LNG, and its applicable volume is 10,000～280,000
Cubic meter, it is -198 DEG C～45 DEG C to be suitable for storage temperature.
The utility model has good filtration, can avoid impurity in immersed pump suction tank, so as to ensure latent liquid
The operation of pump safety and steady.
Advantage of the present utility model is filter effect substantially, but is simple to manufacture, with low cost.

Specific embodiment
Below in conjunction with being described in detail to the utility model content.
As depicted in figs. 1 and 2, the utility model is used for filtering the medium for entering immersed pump well.The utility model
Filter is cylindrical, including base plate 1, screen pack 2, top angle iron frame 3, flat-beam 4 and bottom angle iron frame 6.
Eight flat-beams 4 are welded between the top angle iron frame 3 and bottom angle iron frame 6.Base plate 1, top angle frame
Connected using welding manner between frame 3, flat-beam 4 and bottom angle iron frame 6.
Framework and 4 material selection cryogenic carbon steel or stainless steel of flat-beam.The diameter of circular frame is typically pump sump diameter
1.8～3 times, the thickness of flat-beam 4 is 4mm～8mm, and height is usually 800mm～1200mm.
The screen pack 2 is wrapped on the outside of framework and band steel, is played a role in filtering.2 material selection of the screen pack is stainless
Steel.2 side length of element of screen pack is usually 2mm～4mm, and wire diameter is usually φ 0.8mm～φ 1.5mm.Screen pack 2 and top
Connected using sequential welding mode between angle iron frame 3 and bottom angle iron frame 6, be connected using intermittent weld mode between flat-beam 4.
The filter is provided with base plate 1, prevents impurity in tank from entering from bottom of device.Three should be arranged simultaneously on base plate 1
Individual outage 9, to guarantee not having medium residual during slack tank in filter；Screen pack 2 should be also set at outage, to prevent
Impurity is hence into filter.1 material selection cryogenic carbon steel or stainless steel of base plate.
The filter is fixed on inner canister tank bottom 8 by connecting plate 7 and angle cleat 5, is connected by bolt between the two
Connect, see Fig. 1.Connecting plate 7 is 4～8 with 5 quantity of angle cleat, material selection cryogenic carbon steel or stainless steel.
As shown in figure 3, being welded bottom angle iron frame 6 with base plate 1 during manufacture first, then Welding flat steel stands successively
Post 4 and top angle iron frame 3, have now formed the circular frame of filter.Then screen pack 2 is laid on outside circular frame
In portion and outage, fixed with bottom angle iron frame 6 and top angle iron frame 3 using sequential welding pattern in 2 surrounding of screen pack, and
Are carried out intermittent weld to increase structural strength for screen pack 2 and flat-beam 4.Finally connecting plate 7 is connected with bolt with angle cleat 5
Connect, realize the fixation of filter.
The filter can make two kinds of " integral type " and " removable " according to specific needs.Wherein " integral type " circular frame
The connection of frame adopts welding manner, cannot dismantle after therefore installing." removable " requires that circular frame can be split into two 180 °
Framework, between adopt removable bolt connection.
