The purpose of this utility model is to provide a kind of coke apparent porosity determinator, measures the apparent porosity of coke by vacuum drainage method, has advantages of simple in structure, easy to operate, practical.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of coke apparent porosity determinator, comprise vacuum pump, breather valve, extraction valve, vacuum meter, filling valve, water tank, vacuum tank, burnt sample, water box, controller, it is characterized in that, described water box is arranged in vacuum tank, burnt sample is placed in water box, filling valve connects water tank and water box, and vacuum pump connects extraction valve, and vacuum meter connects vacuum tank.
Described coke size size is between 25mm ~ 60mm.
The described wide 500mm of coke apparent porosity determinator, high 1330mm, dark 570mm.
Compared with prior art, the beneficial effects of the utility model are:
Coke apparent porosity determinator, simple to operate, data are accurate, can be widely used in coal, metallurgy, coking, foreign trade, commodity inspection every profession and trade and University Scientific Research experimental study department.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
The burnt sample 9-of 1-vacuum pump 2-breather valve 3-extraction valve 4-vacuum meter 5-filling valve 6-water tank 7-vacuum tank 8-water box 10-controller
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated:
As shown in Figure 1, coke apparent porosity determinator, by vacuum pump 1, breather valve 2, extraction valve 3, vacuum meter 4, filling valve 5, water tank 6, vacuum tank 7, burnt sample 8, water box 9 and controller 10 form, water box 9 is arranged on 7 li of vacuum tanks, burnt sample 8 is placed on 9 li, water box, filling valve 5 connects water tank 6 and water box 9, vacuum pump 1 connects extraction valve 3, vacuum meter 4 connects vacuum tank 7, burnt sample 8 granule sizes that are used for measuring are between 25mm ~ 60mm, the wide 500mm of coke apparent porosity determinator, high 1330mm, dark 570mm, measuring environment temperature is 10 ~ 40 ℃, humidity is not more than 80%, without high-intensity magnetic field, non-corrosiveness gas.
Before experiment, first burnt sample 8 is clashed into mutually, remove the unstable burnt grain in surface, brush away dust, put into drying box, at 150 ℃ ~ 160 ℃ dry 150 minutes, if burnt sample 8 was soaked or too during humidity, should extend or improve baking temperature drying time.Dry complete, burnt sample 8 is taken out in drying box, be placed in air cooling 5 minutes, be positioned over known quality m
1silk screen basket in weigh M
2, then pack water box 9 into, put into vacuum tank 7, water service pipe one end is placed on to 9 mouthfuls, water box upper, with net sheet, press and add a weight, close vacuum tank 7.Start before coke apparent porosity determinator, water tank 6 is filled to water.
Pneumatic coke apparent porosity determinator, switch is transferred to " automatically " position, vacuum pump 1 starts, and extraction valve 3 is opened, and vacuum tank 7 starts to vacuumize, when vacuum tank 7 pressure are during lower than-0.088MPa, vacuum pump 1 quits work, and extraction valve 3 is closed, about 5 seconds, breather valve 2 is opened, and pipeline surplus pressure is discharged.After five minutes, filling valve 5 is opened, and slowly water-filling, makes water flood burnt sample completely, the time that filled water amount has been preengage by relay is set complete, and after the preset filling time arrives, filling valve cuts out, and water-filling finishes, keep after two minutes, extraction valve 3 is opened, and vacuum tank 7 is connected atmosphere.
Under normal pressure, after standing 30 minutes, from the burnt sample 8 of the interior taking-up of vacuum tank 7, put into known to water suspended load discharge m
3silk screen basket in, weigh the mass M that silk screen basket and the burnt sample 8 of test suspend in water
3, then calculate apparent porosity Ps.
Apparent porosity Ps presses as shown in the formula calculating:
In formula:
M
1---the sample after oven dry and the gross mass of shredded dried bean curd net basket, g;
M
1---the quality of shredded dried bean curd net basket, g;
M
2---the sample after water saturation and the gross mass with drain pan silk screen basket, g;
M
2---with the quality of drain pan silk screen basket, g;
M
3---the quality sum that sample mass after water saturation and silk screen basket suspend in water, g;
M
3---the quality that silk screen basket suspends in water, g.
Between twice parallel experiment result, error must not surpass 2.0%, if error surpasses 2.0% between twice parallel experiment result, test for the third time, while being no more than 2.0% as the difference of any one result in test findings and front twice test for the third time, get the arithmetic mean of immediate result in test findings and front twice test for the third time, while all surpassing 2.0% as the difference of any one result in test findings and front twice test for the third time, but for the third time within the limit range of test findings in front twice test findings, get three results arithmetic mean be test findings.The all right manual operation of coke apparent porosity determinator, every weekly check is the sealing of vacuum tank 7 dimly, when be less than-0.088MPa of surplus pressure, close extraction valve 3, close vacuum pump, five minutes internal pressures change and are not more than 0.004MPa, the quality of silk screen basket and in water suspended load discharge should check once weekly.
