The specific embodiment
Be described in detail below in conjunction with structure and the using method of accompanying drawing to material tank of the present invention.
As shown in Figure 1: material tank of the present utility model comprises at the bottom of tank body 4, the tank 6, bearing 7, loam cake 1 and oil outlet pipe 10.Described tank body 4 is cylindrical tube, and 7 is inverted cone at the bottom of the tank, and wherein the central authorities at the vertex of a cone of described cone are provided with opening, is used for connecting blow-off pipe 9, and valve 8 is set on the blow-off pipe 9.Tank body lower part sets out oil pipe 10 near the tank bottom, and the mouth of pipe of oil outlet pipe 10 is positioned at the tank body centre, at oil outlet pipe valve 11 is set.Wherein also be provided with fluid distributor 2 on the top of tank body 4, described fluid distributor comprise a bottom be blind plate, tube wall opening uncovered cylinder 13 with the uncovered annulus that is connected 14.
Wherein 6 material is for being generally 304 corrosion-resistant steels at the bottom of tank body 4 and the tank, and tank body 4 is the uniform cylindrical tube of diameter, and 6 is cone at the bottom of the tank, and tapering is generally 5:1 ~ 30:1.
The material of fluid distributor 2 is 304 corrosion-resistant steels, and it is shaped as inverted " carnival hat " shape, specifically comprise a bottom be blind plate, tube wall opening uncovered cylinder 13 with the uncovered annulus that is connected 14.The external diameter of annulus 4 generally is greater than the external diameter of tank body, and annulus can cover the heating jacket of tank body 4 outsides like this, and oil product is dropped on the heating jacket and causes potential safety hazard when avoiding refueling.Have several deflation holes at annulus " shade ", be generally 1.Freeing pipe 12 passes deflation hole, and the upper end is concordant with annulus.The diameter of " cap cylinder " that uncovered cylinder 13 forms is 1/4 ~ 3/4 times of tank body 4 diameters.The height of uncovered cylinder is to be generally 1/6 ~ 1/2 of tank body 4 height.The barrel of uncovered cylinder has the identical circular port of some diameters, and percent opening is generally 50% ~ 100%.The bottom surface of uncovered cylinder is blind plate structure.
Fluid distributor 2 belows can also arrange pre-filtering plate 3, and pre-filtering sheet material matter is 304 corrosion-resistant steels, can disassemble from tank body 4 easily.Pre-filtering plate 3 is a plectane that has some apertures, and its diameter is slightly less than the diameter of tank body 4, with between the tank body 4 for airtight the connection.Tank body 4 upper inner are provided with several fulcrums of well-distributed, and pre-filtering plate 3 is placed on the fulcrum.On the pre-filtering plate 3 with the fluid distributor annulus on corresponding position have some deflation holes, freeing pipe 12 passes deflation hole and runs through the pre-filtering plate.Freeing pipe 12 and pre-filtering plate 3 are for closely to be connected.The material of freeing pipe 12 is 304 corrosion-resistant steels.
The utility model material tank using method is as follows:
Add in the stock tank for the first time before the feed oil, at first unload lower nozzle filter 5, check whether it has obstruction, stop up the filter that cleans or more renew if having, then install with 6 wiped clean at the bottom of loam cake 1, fluid distributor 2, pre-filtering plate 3, tank body 4 and the tank, and with pre-filtering plate 3, fluid distributor 2 and freeing pipe 12.After installing, close blow-off pipe valve 8 and oil outlet pipe valve 11.In oil tank, add feed oil, after feed oil is fallen on the fluid distributor 2, the direction of feed oil becomes radial direction, its whereabouts kinetic energy is weakened greatly, then feed oil flow on the pre-filtering plate 3, and feed oil is divided into evenly tiny liquid stream or drop by the aperture on the pre-filtering plate 3 and enters tank body 4, and the larger particulate matter of part can be deposited on the screen plate 3 in the feed oil, feed oil enters in the process of tank body 4, and the gas in the tank body is discharged from freeing pipe 12.After material tank is filled it up with, loam cake 1 is covered, leave standstill a period of time
,Then open blow-off pipe valve 8, solid impurities and the water in the feed oil of deposition are discharged, guarantee that solid impurities and water are not brought in the upstream device.Then close blow-off pipe valve 8, open oil outlet pipe valve 11, feed oil enters and enters oil pump after mouth of pipe filter 5 further filters, because the open area of mouth of pipe filter 5 is large, its in running condition is difficult for blocked, can the continuous oil-feed of assurance device.
Device along with the continuous decline of the oil product liquid level in the stock tank, just need to add feed oil after running a period of time in stock tank.At this moment, should open first blow-off pipe valve 8, the solid impurities and the water in the feed oil that are deposited at the bottom of the tank 6 are discharged, then close blow-off pipe valve 8, the beginning refueling operation.Under the effect of fluid distributor 2 and pre-filtering plate 3, feed oil is divided into evenly tiny liquid stream or drop and enters tank body 4, greatly reduce refueling process to the impact of remaining liquid in the tank, so that the solid impurities in 6 can because of the impact back-mixing that makes progress, not prevent that bubble from entering oil outlet pipe simultaneously yet at the bottom of the tank.After material tank is filled it up with, loam cake 1 is covered, leave standstill a period of time (normal oil-feed this moment)
,Then open blow-off pipe valve 8, solid impurities and the water in the feed oil of deposition are discharged, guarantee that solid impurities and water are not brought into the downstream.
