Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:

As shown in Figures 1 to 4, the oil tank porous buffer oil inlet device of the present utility model is arranged in the tank body 1, including an oil inlet pipe 2 installed vertically for accessing oil products, and installed horizontally at the bottom of the tank body 1 The upper buffer pipe 3 and the connector connecting the oil inlet pipe 2 and the buffer pipe 3 have at least one oil outlet hole 4 on the top of the buffer pipe 3, and the oil inlet device has an "L" shape structure.

In this embodiment, thirteen oil outlet holes 4 are equally spaced on the top of the buffer pipe 3, and the net distance between two adjacent oil outlet holes 4 is 0.2m, that is, two adjacent oil outlet holes 4 The shortest distance between the edge and the edge is 0.2m. The diameter of the oil outlet hole 4 gradually increases along the flow direction of the oil product. The opening size and corresponding cross-sectional area of the oil outlet hole are shown in Table 1:

Hole number diameter (mm) Cross-sectional area (mm ² ) one 10 78.5 two 15 176.625 three 20 314 Four 25 490.625 five 30 706.5 six 35 961.625 seven 40 1256 eight 45 1589.625 Nine 50 1962.5 ten 55 2374.625 eleven 60 2826 twelve 65 3316.625 Thirteen 70 3846.5 Original oil pipeline 80 5024

Table 1

Add the cross-sectional area of each oil outlet hole in Table 1, so that the total cross-sectional area of the oil outlet hole of the oil inlet device is 19899.75mm ² , which is about 4 times the cross-sectional area of the original oil outlet pipe, which can effectively slow down the oil flow rate and reduce the The impact force of the oil product can reduce the impact and agitation of the oil product on the water impurities at the bottom of the tank, prevent the impurities at the bottom of the tank from floating up and mixing with the oil product, and ensure the quality of the oil product.
