Embodiment 1
[0043] see Figure 1-4 , a device for measuring material density and sorting materials through magnetic fluid, it includes two sets of matching and using devices, wherein the bottom end of the first set of devices is equipped with a storage battery 1, and the storage battery 1 is connected with the current intensity regulator 2 The electromagnets 3 are connected, and the first glass tube 6 is arranged between the electromagnets 3; the second set of devices includes a height-adjustable bracket 13, and the top of the bracket 13 is obliquely equipped with a second glass tube 10, The top of the second glass tube 10 is processed with a plurality of evenly distributed glass tube holes 11 , and a plurality of magnets 12 are installed on the second glass tube 10 at equal intervals.
[0044] Further, the storage battery 1 is a rechargeable storage battery, the storage battery 1 is provided with a charging port 9, the storage battery 1 is provided with a switch 8 for turning on the powe...
Embodiment 2
[0051] The method of any one of the devices for measuring the density of substances and sorting substances through magnetic fluids is characterized in that it comprises the following steps:
[0052] Step 1: Pour the ferrofluid 4 into the first glass tube 6 of the first set of devices, and then put in the non-metallic test object 5 that is incompatible and reactive with the ferrofluid;
[0053] Step 2: Turn on the power supply 1, increase the current intensity regulator 2, and increase the magnetic field emitted by the electromagnet, thereby increasing the density of the ferrofluid 4 and making the non-metallic object 5 float on the ferrofluid 4. At this time Repeatedly adjust the current to find the critical point where the object under test sinks;
[0054] Step 3: Use the magnetic field strength corresponding to the current regulator at this time to find the corresponding density value on the magnetic field strength-density curve obtained in the previous test, so as to obtain...
Embodiment 3
[0056] The method of any one of the devices for measuring the density of substances and sorting substances through magnetic fluids is characterized in that it comprises the following steps:
[0057] Step 1: When the non-metallic test object 5 is composed of substances with different densities, crush the non-metallic test object 5 into powder and put it into the first glass tube 6;
[0058] Step 2: Increase the density of the magnetic fluid 4, so that all non-metallic objects 5 to be tested float on the magnetic fluid 4, slowly reduce the density of the magnetic fluid 4, and when there is a substance with a density lower than the density of the magnetic fluid 4, it will sink , extract the sinking material at this time and record the density corresponding to the magnetic field at this time;
[0059] Step 3: Repeat the above steps to sort out objects with different densities, and get their corresponding density values, and finally get the density components of the mixture;
