Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a device for measuring the content of magnetic substances in liquid. Background Art

[0002] Magnetic material content detection is a technical measure to determine the content of magnetic material (kg / m3) in the heavy suspension with magnetic material as weighting material. The heavy suspension of heavy medium coal preparation is mainly composed of magnetite, non-magnetic material and water. The content of magnetite in the heavy suspension directly affects the density, rheological properties, product quality and efficiency of the suspension.

[0003] In the process of oil drilling, barite powder is often used as a weighting agent, which contains a large amount of magnetic substances. When the content of these magnetic substances exceeds a certain limit, they will gather in the control unit of the rotary steerable drilling system, causing system abnormalities. At present, a magnetic substance measuring instrument is mostly used to detect the content of magnetic substances in liquids. The device is equipped with a glass tube between the two poles of a C-shaped electromagnet, which moves back and forth and swings. When the tested material sample and water pass through the magnetic field area, the magnetic substances adhere to the tube wall of the two poles, and the non-magnetic substances are washed out by water during mechanical movement. However, the two poles of the C-shaped electromagnet in the device are small. When the liquid passes through, the adsorption force for the magnetic substance is small. When the content of magnetic substances in the liquid is large, the magnetic substances cannot be completely adsorbed. The magnetic substances will flow out of the tube with the water flow, resulting in the loss of magnetic substances, affecting the accuracy of the test results. In addition, due to the short liquid flow path, the determination efficiency of magnetic substances is low. Therefore, there is an urgent need for a device that can accurately measure the content of magnetic substances in liquids to meet industry needs. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example:

[0028] like Figures 1 to 5As shown, a device for measuring the content of magnetic substances in liquid comprises a base 6, a vertical plate 5 for supporting a top plate 4 is fixedly arranged on the left side of the upper end surface of the base 6, the upper end of the vertical plate 5 is horizontally fixedly connected to the top plate 4, a liquid storage cylinder 2 is fixed to the upper side of the top plate 4 through a fixed bracket 3, an iron core 16 is fixedly arranged on the right side of the lower end surface of the top plate 4, a plurality of groups of coils 17 are wound on the annular surface of the iron core 16, a magnetic rod 19 is fixedly connected to the lower side of the iron core 16, two groups of measuring tubes 7 are sleeved on the annular surface of the magnetic rod 19, a liquid outlet pipe 10 is connected to the bottom of the liquid storage cylinder 2, a regulating valve 11 is installed at the lower end of the liquid outlet pipe 10, and the regulating valve 11 is installed at the lower end of the regulating valve 11. 1 is equipped with a three-way joint 12 at the lower side, and two interfaces at the lower side of the three-way joint 12 are connected with a hose 13, and the lower end of the hose 13 is connected to the measuring tube 7. This design solves the problem that the two poles of the C-shaped electromagnet in the existing magnetic object detection device are small in area, and the adsorption force on the magnetic material is small when the liquid passes through. When the content of magnetic material in the liquid is large, the magnetic material cannot be completely adsorbed, and the magnetic material will flow out of the tube with the water flow, resulting in the loss of magnetic material, affecting the accuracy of the detection result, and because the liquid flow path is short, the determination efficiency of the magnetic material is low.

[0029] A flushing cylinder 1 is fixed to the rear side of the liquid storage cylinder 2 through a fixed bracket 3. The bottom of the flushing cylinder 1 is connected to the liquid outlet pipe 10 through an inclined flushing water pipe 8. The middle section of the flushing water pipe 8 is equipped with a regulating valve 9. The design can store clean water through the flushing cylinder 1, and can flush the magnetic material adsorbed by the magnetic field in the measuring tube 7, clean the impurities adhering to the surface of the magnetic material, ensure the purity of the magnetic material, and facilitate flushing the measuring tube 7 after the test is completed to avoid the residual magnetic material from affecting the next test. The regulating valve 9 can control the flow of the flushing water flow, which not only ensures the flushing effect, but also saves water resources.

[0030] The two groups of measuring tubes 7 are both spiral structures made of non-magnetic materials, and the spiral directions of the two groups of measuring tubes 7 are the same. The two groups of measuring tubes 7 are staggered and sleeved on the magnetic rod 19. This design not only increases the contact area between the liquid and the magnetic field, and improves the adsorption efficiency of the magnetic material, but the spiral structure can also extend the flow path of the liquid, thereby improving the measurement efficiency.

[0031] A cavity 18 is provided inside the base 6, and its opening is located at the front side of the base 6. A collecting box 14 is placed inside the cavity 18, and the lower end of the measuring tube 7 is connected to the cavity 18. The collecting box 14 can conveniently collect the liquid and magnetic material flowing out of the measuring tube 7, which is convenient for subsequent processing and analysis.

[0032] A handle 141 is fixedly provided on the front side of the collection box 14 . The handle 141 allows an operator to easily grab and move the collection box 14 , making it convenient to take out and replace the collection box 14 .

[0033] The outer side of the iron core 16 and the coil 17 is covered with a protective cover 15, and the upper end of the protective cover 15 is fixedly connected to the top plate 4. The design of the protective cover 15 plays a role in protecting the electromagnet and the coil 17 to prevent the intrusion of dust and liquid.

[0034] The bottom of the base 6 is equipped with rubber pads 20 near the four corners. The design of the pads 20 increases the friction between the base 6 and the ground, ensuring the stability of the device.

[0035] The measuring tube 7 is made of transparent glass material, which is convenient for observing the flow of liquid in the measuring tube 7 and the adsorption of magnetic substances. The measuring tube 7 made of glass material has a smooth inner wall, which is convenient for the magnetic substances adsorbed inside to slide out completely after the measurement is completed, avoiding the residue of magnetic substances.

[0036] The working principle of the device for measuring the content of magnetic substances in liquid is as follows: first, the coil 17 on the iron core 16 should be energized to generate a magnetic field, and then the liquid to be detected is weighed to measure the volume and poured into the liquid storage cylinder 2. By adjusting the regulating valve 11 at the lower end of the liquid outlet pipe 10, the flow rate of the liquid flowing into the three-way joint 12 can be controlled. The three-way joint 12 divides the liquid into two hoses 13, and then flows into two groups of measuring tubes 7. When the liquid flows through the measuring tubes 7, the magnetic substances therein are affected by the strong magnetic field generated by the iron core 16 and the coil 17, and are adsorbed on the inner wall of the measuring tube 7. The magnetic substances adsorbed on the inner wall of the measuring tube 7 are separated from the liquid, and the liquid continues to flow and flows into the cavity 18 inside the base 6 through the lower port of the measuring tube 7, and is finally collected in the collection box 14, while the magnetic substances remain on the inner wall of the measuring tube 7. When all the liquid in the liquid storage cylinder 2 has flowed out, the regulating valve 9 under the flushing cylinder 1 is opened, and the measuring tube 7 is flushed with clean water to remove the impurities adsorbed on the surface of the magnetic material, and the waste water after flushing also flows into the collection box 14. Then the operator replaces the new collection box 14 and puts it into the cavity 18, and turns off the power supply of the coil 17. After the coil 17 is powered off, the magnetic field on the magnetic rod 19 disappears, and the magnetic material adsorbed on the inner wall of the measuring tube 7 slides down and falls into the collection box 14. Then the magnetic material in the collection box 14 is dried and weighed, and then calculated and analyzed to determine the content of the magnetic material in the liquid.

[0037] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
