Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1, the utility model embodiment provides a kind of measurement mechanism of oil-water interface position, comprising: solid aluminum ball 2, fixed pulley 3, explosion-proof steel wire 4, counterweight 5, two-way altitude scale 6.
Fixed pulley 3 is vertically fixed on the top perimeter place measuring mouth near slurry tank 1 top.One end of explosion-proof steel wire 4 is fixedly connected with solid aluminum ball 2, the other end is fixedly connected with counterweight 5, explosion-proof steel wire 4 can move around fixed pulley 3, to drive solid aluminum ball 2 to carry out relative axially-movable with counterweight 5, on the water-oil interface B that solid aluminum ball 2 is suspended in slurry tank 1.As shown in Figure 2, two-way altitude scale 6 is vertically fixed on the outer wall of slurry tank 1, comprises left side altitude scale 601 and right side altitude scale 602, and counterweight 5 hangs on the centre of left side altitude scale 601 and right side altitude scale 602 non-contiguously.
The measurement mechanism of the oil-water interface position that the utility model embodiment provides, utilize the feature of fixed pulley 3 both sides stress balance, equilibrium state is kept under making the solid aluminum ball 2 pulling force effect that counterweight 5 is executed on the buoyancy and explosion-proof steel wire 4 at self gravitation, water-oil interface B place, in order to keep this equilibrium state, the position of solid aluminum ball 2 changes according to the change of water-oil interface B, counterweight 5 is connected by explosion-proof steel wire 4 with solid aluminum ball 2, and its position also changes accordingly.The height value of counterweight 5 and the height value of solid aluminum ball 2 can be read by the two-way altitude scale 6 of counterweight 5 both sides, wherein, the height value of solid aluminum ball 2 and the depth value of water-oil interface B position.Visible, the measurement mechanism that the utility model embodiment provides can draw rapidly the depth value of water-oil interface B in slurry tank 1 by the reading of two-way altitude scale 6, more intuitive and reliable, and counterweight 5 can adjust automatically according to the position of water-oil interface B, thus handled easily personnel can enter Water Tank by oily suction storage tank or by sewage in time, without the need to manually repeatedly sampling, easy and simple to handle, time saving and energy saving, with low cost.
Wherein, the material of solid aluminum ball 2 is commercial-purity aluminium.The utility model embodiment selects commercial-purity aluminium as the material of solid aluminum ball 2 based on following two reasons: one is that the density of oil is less, bead made by the material little according to density, buoyancy suffered by bead can be caused to be greater than self gravitation, thus be suspended in oil reservoir surface A, be even subject to the traction of counterweight 5 and depart from slurry tank 1; Two is compared with other metal materials, the medium density of aluminium, both can meet under sinking to oil reservoir surface A, and under the condition that volume is identical, the quality of solid aluminum ball 2 is less, the gravity be subject to is less, but suffered buoyancy is identical, thus the required quality for the counterweight 5 balanced is less, less to the pulling force of explosion-proof steel wire 4, make operation safer, laborsaving, easy.
Particularly, the specification of solid aluminum ball 2 comprises 2.7kg, 5.4kg, 8.1kg, 10.8kg.In actual mechanical process, according to the concrete specification of slurry tank 1, and the hybrid density that water-oil interface B is concrete, correspondingly can choose the solid aluminum ball 2 of different size.
As preferably, the utility model embodiment is by the top perimeter place be vertically fixed near slurry tank 1 top measurement mouth by fixed pulley 3, and ensure that the sidewall of the center line of fixed pulley 3 and the slurry tank 1 at fixed position place is on same straight line, not only ensure explosion-proof steel wire 4 stress balance around its motion, thus ensure the accurate of reading, and the accuracy of judgement of water-oil interface B position.And explosion-proof steel wire 4, solid aluminum ball 2, counterweight 5 all can not be contacted with slurry tank 1, to prevent because friction produces spark, thus cause the security incidents such as crude oil blast.
As preferably, the surface application of explosion-proof steel wire 4 has explosion-proof layer.Particularly, explosion-proof layer is epoxy coating, and thickness is 0.48-0.52mm, is preferably 0.5mm.The diameter of explosion-proof steel wire 4 is 2.4-2.6mm, is preferably 2.5mm.
Particularly, as shown in Figure 2, counterweight 5 comprises: the instruction counterweight 501 be fixedly connected with explosion-proof steel wire 4 and be added in the one or more weights 502 indicated on counterweight 501.The unsettled placement of counterweight 5, does not contact with miscellaneous part, can ensure that the pulling force of the explosion-proof steel wire 4 suffered by counterweight 5 pairs of solid aluminum balls 2 equals the gravity of counterweight 5 self like this, and then ensures that solid aluminum ball 2 is suspended among water-oil interface B, makes measurement more accurate.
Particularly, the specification of weights 502 comprises 0.001kg, 0.002kg, 0.005kg, 0.01kg, 0.02kg, 0.05kg, 0.1kg, 0.2kg, 0.5kg, 1kg, 3kg, 5kg.

solid aluminum ballfor the gravity suffered by solid aluminum ball 2, F
buoyancyfor the buoyancy suffered by solid aluminum ball 2, G
counterweightfor the gravity suffered by counterweight 5, g is acceleration of gravity.
According in actual mechanical process, sampling records the hybrid density of water-oil interface B, according to the specification of used solid aluminum ball 2, calculates the quality of required counterweight 5, deducts the quality of instruction counterweight 501, i.e. the quality of weights 502.
Particularly, as shown in Figure 2, the meter full scale of left side altitude scale 601 is 0-10m, increases gradually from the bottom to top; The meter full scale of right side altitude scale 602 is 0-10m, from top to bottom increases gradually.Left side altitude scale 601 shows the height of counterweight 5, and due to the total length of explosion-proof steel wire 4 certain, accordingly, right side altitude scale 602 shows the height of solid aluminum ball 2 in slurry tank 1, i.e. the depth value of water-oil interface B.
Further the present invention will be described by specific embodiment.
