Description

Technical Field

[0001] The invention relates to the technical field of sintering, and in particular to an online detection device for moisture content of a sintering mixture. Background Art

[0002] In the sintering process, in order to make the physical and chemical properties of the sintered materials fully uniform, it is necessary to first make the fine particles in the sintering materials into small balls of suitable sizes. Therefore, a mixing process is set up after the batching, and the amount of water added in the mixing process has a direct impact on the subsequent mixing and balling effect. The current sintering production line is usually equipped with a moisture meter behind the unloading point of the first mixed discharging belt conveyor and the unloading point of the second mixed discharging belt conveyor, which is used to detect the moisture content in the mixed materials in real time, so as to adjust the moisture content of the materials at any time and control the moisture content of the materials within the process limit range, and finally achieve the purpose of stabilizing the quality of the sintered ore.

[0003] The Chinese invention patent with the authorization announcement number CN 101866188 B discloses "an automatic control system for moisture content of sintered mixtures". By measuring the wet capacity of the sintered mixture, the appropriate moisture content of the sintered mixture is predicted based on the wet capacity, and the amount of water added during the granulation process is adjusted and controlled based on the predicted value of the appropriate moisture content and the actual moisture content detected online, so that the moisture content of the sintered mixture is finally stabilized at an appropriate value, thereby realizing the automatic control and online real-time control of the optimal water distribution amount in the granulation process, effectively improving the current disadvantage of difficult to ensure the accuracy of manual control of water distribution, and greatly reducing the labor intensity of operators; at the same time, the control stabilization time is short and the fluctuation is small, which effectively improves the disadvantage of water distribution error caused by objective factors such as climate change.

[0004] During the online detection of moisture in sintered mixtures, the measurement accuracy of the moisture meter is closely related to the installation angle and the distance between the moisture meter and the measured material. At present, in the actual production process of sintered ore, its output changes at any time, and the discharge amount of sintered mixtures will also change accordingly. Correspondingly, the height of the material surface on the mixer discharge belt will also change at any time. When the material surface height changes too much, it will affect the measurement accuracy of the moisture meter. In addition, when the discharge amount of the sintered mixture after the mixer suddenly increases, the material surface that instantly rises during transportation may collide and contact with the moisture meter, resulting in failure or damage to the moisture meter. In addition, the environment at the sintered ore production site is usually harsh, and the moisture meter, as a precision detection instrument, sometimes fails, and the moisture meter needs to be frequently repaired. The installation of the moisture meter is required to facilitate online maintenance. If the failure of the moisture meter is difficult to solve in time, the data of the moisture content of the sintered mixture cannot be obtained in time, thereby affecting the control and adjustment of the amount of water added to the sintered mixture.

[0005] The Chinese utility model patent with authorization announcement number CN 218885849 U discloses "a protective device for measuring the probe of a moisture meter for sintering mixtures". A material dividing part and a probe protection part are arranged on the mixture belt in sequence according to the running direction of the mixture belt; two material dividing plates and one material dividing baffle in the material dividing part form an isosceles triangle structure, and the isosceles triangle structure is fixed to the ceiling bracket of the belt corridor through a mounting plate; the probe protection part includes a movable bracket, a moisture meter protection box bottom plate and a moisture meter protection box, and the movable bracket includes a rotating shaft, a rotating plate, a horizontal support plate and a material anti-collision baffle. When the material flow is large or the material surface is higher than the lower surface of the moisture meter protection box, it can divert the mixture so that it does not hit the moisture meter probe, so that the moisture value of the mixture is continuously measured and the moisture meter is protected; when the mixture is too large, the mixture can pass through the top of the dividing plate to prevent the mixture from being scattered to the outside of the belt. When the mixture passing through the top of the dividing plate hits the movable bracket, the movable bracket 7 can swing upward with the direction of the mixture flow to prevent the moisture meter probe from being knocked off by the mixture. However, the dividing part and the moisture meter protection box set up are large in volume, and both are set on the moving path of the sintered mixture, which will cause great resistance to material transportation and seriously affect the material transportation efficiency; in addition, although the dividing plate set up can guide excess material to the top of the dividing plate, the material on the top lacks sufficient driving force and will accumulate on the dividing plate for a long time, increasing the overall stress of the device and adversely affecting the stability of the device.

[0035] The control system is a PLC controller.

[0036] The flat plate 34 is a rubber scraper.

[0037] The sintering material mixer comprises a sintering material primary mixer and a sintering material secondary mixer.

[0038] The moisture meter 27 is an online infrared moisture meter.

[0039] The device for online detection of moisture in sintered mixtures described in the present invention can more conveniently adjust the installation angle and installation position (including height and horizontal position) of the moisture meter, and can disassemble and install the moisture meter online. By installing a protective mechanism upstream of the moisture meter, it can prevent the sintered mixture surface on the discharging belt conveyor from interfering with or colliding with the moisture meter when it suddenly increases.

[0040] The sintering mixture moisture online detection device of the present invention comprises a moisture meter installation unit 2 and a moisture meter protection unit 3; in the moisture meter installation unit 1, U-shaped bolts are used as connecting parts between the column 1 22 and the beam 1 21, and between the beam 1 21 and the mounting seat 25. The U-shaped bolts can be used to quickly adjust the angle and installation position of the moisture meter 27. In the moisture meter protection unit 3, U-shaped bolts are also used as connecting parts between the column 2 32 and the beam 2 31. The U-shaped bolts can be used to quickly adjust the installation position of the flat plate 34 (and the rangefinder 4).

[0041] In the moisture meter installation unit 2, both ends of the beam 21 are connected to the column 22 by U-bolts 24. The U-bolts 24 can be used to conveniently adjust the height of the beam 21 from the belt surface of the discharge belt 1 (that is, the height from the surface of the sintered mixture), and the beam 21 can be removed from the column 22 for maintenance at any time. The mounting seat 25 is also connected to the beam 21 by U-bolts (mounting bolts 26). The U-bolts can be used to adjust the installation angle of the moisture meter 27 and the installation position of the moisture meter 27 along the longitudinal direction of the beam 21 at any time, and the moisture meter 27 can be removed at any time for debugging and maintenance. The problem that the moisture meter cannot be disassembled and debugged during the operation of the discharge belt is solved, the measurement continuity and timeliness of the moisture meter are guaranteed, and the moisture content in the sintered mixture can be controlled more accurately.

[0042] The moisture meter protection unit 3 is installed at a distance upstream of the moisture meter installation unit 2. The second crossbeam 31 and the second column 32 are connected by U-bolts 33. The height of the second crossbeam 31 is adjustable. When in use, the height of the flat plate 34 on the second crossbeam 31 is adjusted to be slightly lower than the height of the bottom surface (probe end) of the moisture meter 27 (when a hydraulic cylinder 28 is provided, the height of the flat plate 34 is adjusted to a position slightly lower than the bottom surface of the moisture meter 27 when it is in the highest position). When the height of the sintered mixed material surface is higher than the height of the flat plate 34, the flat plate 34 is used to limit the height of the material surface to prevent the sintered mixed material from directly contacting the moisture meter 27.

[0043] The installation process of the online detection device for moisture content of sintering mixture described in the present invention is as follows:

[0044] Step 1: First, weld the seat plate 1 at the bottom of the column 1 22 of the moisture meter installation unit 1, and then weld and fix the seat plate 1 on the frame longitudinal beam of the discharge belt conveyor 1 downstream of the unloading point of the sintering material mixer. After welding, the column 1 22 is in a vertical state.

[0045] Step 2: Weld the connecting angle steels 23 at both ends of the beam 1 21, open bolt holes on the connecting angle steels 23 on both sides of the beam 1 21, and use U-bolts 24 to connect the connecting angle steels 23 and the column 1 22, so that the beam 1 21 is fixed horizontally above the belt surface of the discharge belt conveyor 1. Use U-bolts (mounting bolts 26) to install the mounting seat 25 on the beam 1 21, and then hang the moisture meter 27 on the mounting seat 25 (or hang the hydraulic cylinder 28 on the mounting seat 25, and then install the moisture meter 27 on the lower end of the cylinder rod of the hydraulic cylinder 28 through the mounting plate 29), ensuring that the probe of the moisture meter 27 is perpendicular to the belt surface of the discharge belt conveyor 1.

[0046] Step 3: Weld the seat plate 2 at the bottom end of the column 2 32 of the moisture meter protection unit 3, and then weld and fix the seat plate 2 on the frame longitudinal beam of the discharge belt conveyor 1 between the unloading point of the sintering material mixer and the moisture meter installation unit 2. The column 2 32 after welding is in a vertical state.

[0047] Step 4: The second crossbeam 31 is made of angle steel, bolt holes are opened at both ends of the second crossbeam 31, and the second crossbeam 31 and the second column 32 are directly fixedly connected using the second U-bolts 33. After installation, the second crossbeam 31 is in a horizontal state.

[0048] The adjustment method of the online detection device for moisture content of sintered mixture described in the present invention: by loosening the nut matched with the U-bolt 24, the connection between the crossbeam 21 and the column 22 can be loosened, and the height of the crossbeam 21 can be adjusted up and down at this time, and the crossbeam 21 can be directly removed from the column 22 together with the moisture meter 27 (or the crossbeam 21 together with the hydraulic cylinder 28 and the moisture meter 27) to achieve online disassembly and maintenance of the moisture meter 27. By loosening the nut matched with the mounting bolt 26, the connection between the crossbeam 21 and the mounting seat 25 can be loosened, and the mounting seat 25 can be rotated or moved to adjust the installation angle and the longitudinal position of the moisture meter 27 along the crossbeam 21. Similarly, the moisture meter 27 can be directly removed from the crossbeam 21 together with the mounting seat 25 (or the moisture meter 27 together with the hydraulic cylinder 28 and the mounting seat 25) to achieve online disassembly and maintenance of the moisture meter 27.

[0049] By loosening the nut matched with the U-bolt 233, the connection between the beam 231 and the column 232 in the moisture meter protection unit 3 can be loosened, thereby adjusting the upper and lower heights of the beam 231 and adjusting the height of the flat plate 34 on the beam 231 to be slightly lower than the height of the moisture meter 27 probe.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
