Description

Technical Field

[0001] This utility model relates to the field of sintering technology, and in particular to an online moisture detection device for sintering mixtures. Background Technology

[0002] In the production of sintered ore, to ensure the uniformity of the physicochemical properties of the sintered material, it is necessary to first form the particulate material within the sintering feed into small pellets of appropriate size. Therefore, a mixing process is included after batching. The amount of water added during this mixing process directly affects the subsequent mixing and pelletizing effect. Current sintered ore production lines typically install moisture meters after the discharge points of the primary mixing conveyor and the secondary mixing conveyor. These meters are used to monitor the moisture content of the mixed material in real time, facilitating adjustments to the moisture content and controlling it within the process limits to ultimately stabilize the quality of the sintered ore.

[0003] Chinese invention patent CN 101866188 B discloses an "Automatic Moisture Control System for Sintered Mixtures." This system measures the moisture content of the sintered mixture, predicts its optimal moisture content based on this moisture content, and adjusts and controls the amount of water added during granulation based on the predicted optimal moisture content and the actual moisture content detected online. This stabilizes the moisture content of the sintered mixture at an optimal value, thus achieving automated and real-time online control of the optimal water distribution during granulation. This effectively overcomes the shortcomings of current manual water distribution control, which struggles to guarantee accuracy, and significantly reduces the workload of operators. Furthermore, the system features short stabilization time and minimal fluctuations, effectively mitigating the errors in water distribution caused by objective factors such as climate change.

[0004] In the online detection of moisture content in sintered mixtures, the measurement accuracy of the moisture meter is closely related to its installation angle and the distance between it and the material being measured. Currently, in actual sinter production, the output is constantly changing, and the discharge rate of the sintered mixture also changes accordingly, resulting in variations in the material level on the mixer's discharge conveyor belt. Excessive changes in material level can affect the accuracy of the moisture meter. Furthermore, when the discharge rate of the sintered mixture after the mixer suddenly increases, the rapidly rising material level during transportation may collide with or come into contact with the moisture meter, leading to malfunction or damage. Additionally, the environment at sintering production sites is typically harsh, and as a precision measuring instrument, the moisture meter can malfunction, requiring frequent maintenance. Therefore, the installation of the moisture meter must facilitate online maintenance. If moisture meter malfunctions are difficult to resolve promptly, data on the moisture content of the sintered mixture cannot be obtained in a timely manner, thus affecting the control and adjustment of the water addition to the sintered mixture.

[0005] Chinese utility model patent CN 218885849 U discloses a "protective device for a probe of a moisture meter for measuring sintered mixtures". The device consists of a material distribution section and a probe protection section arranged sequentially along the belt conveyor in the direction of belt movement. The material distribution section comprises two distribution plates and one distribution baffle forming an isosceles triangle structure, which is fixed to the belt conveyor canopy support by a mounting plate. The probe protection section includes a movable support, a moisture meter protection box base plate, and a moisture meter protection box. The movable support 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 level is higher than the lower surface of the moisture meter protection box, it can divert the mixture to prevent it from hitting the moisture meter probe. This allows for continuous measurement of the moisture value of the mixture while protecting the moisture meter. When the mixture is too large, it can pass over the distribution plate to prevent it from spilling onto the conveyor belt. When the mixture above the distribution plate hits the movable support, the movable support 7 can swing upward with the direction of the mixture flow to prevent the moisture meter probe from being knocked off. However, the distribution section and the moisture meter protection box are relatively large, and both are located on the movement path of the sintered mixture, which will cause great resistance to material conveying and seriously affect the material conveying efficiency. In addition, although the distribution plate can guide excess material to the top of the distribution plate, the material at the top lacks sufficient pushing force and will accumulate on the distribution plate for a long time, increasing the overall stress on the device and adversely affecting the stability of the device. Summary of the Invention

[0030] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0031] like Figure 1 As shown, the online moisture detection device for sintered mixtures of this utility model includes a moisture meter mounting unit 2 and a moisture meter protection unit 3; as Figure 2As shown, the moisture meter mounting unit 2 consists of a moisture meter 27 and a moisture meter mounting bracket. The moisture meter mounting bracket is installed on the discharge conveyor belt 1 downstream of the sintering material mixer. The moisture meter mounting bracket is an inverted U-shaped bracket, with both ends fixed to the frame of the discharge conveyor belt 1. The moisture meter 27 is installed in the middle of the moisture meter mounting bracket, and the installation angle and height of the moisture meter 27 are adjustable. The probe of the moisture meter 27 faces the sintering mixture surface of the discharge conveyor belt below. Figure 3 As shown, the moisture meter protection unit 3 consists of a flat plate 34 and a flat plate mounting bracket. The flat plate mounting bracket is installed on the discharge conveyor belt 1 downstream of the sintering material mixer and upstream of the moisture meter installation unit 2. The flat plate mounting bracket is an inverted U-shaped bracket, with its two ends fixed to the frame of the discharge conveyor belt 1. The flat plate 34 is installed in the middle of the flat plate mounting bracket. The length of the flat plate 34 is greater than the width of the sintering mixture surface on the discharge conveyor belt, and the installation height of the flat plate 34 can be adjusted. The moisture meter 27 and the flat plate 34 are both located above the belt of the discharge conveyor belt 1, and the bottom surface of the flat plate 34 is lower than the bottom surface of the moisture meter 27.

[0032] like Figure 4 , Figure 5 As shown, the moisture meter mounting bracket consists of a crossbeam 21, two columns 22, connecting angle steel 23, U-bolts 24, a mounting base 25, and mounting bolts 26. The lower end of the column 22 is fixedly connected to the frame of the discharge conveyor belt 1. The two ends of the crossbeam 21 are detachably connected to the corresponding column 21 via connecting angle steel 23 and U-bolts 24. Connecting angle steel 23 is welded to both ends of the crossbeam 21. The U-bolts 24 are fitted onto the outside of the column 21, and the threaded ends of the U-bolts 24 pass through the bolt holes on the connecting angle steel 23 and are then locked in place by nuts. The mounting base 25 is an inverted T-shaped structure composed of a vertical plate and a horizontal plate. Bolt holes are opened on the vertical plate of the mounting base 25. The mounting bolts 26 are U-bolts. Both sets of mounting bolts 26 are fitted onto the outside of the crossbeam 22. The threaded ends of the mounting bolts 26 pass through the bolt holes on the mounting base 25 and are then locked in place by nuts. The moisture meter 27 is installed at the bottom of the horizontal plate of the mounting base 25.

[0033] The flat plate mounting bracket consists of a second crossbeam 31, two second columns 32, and two U-bolts 33. The lower end of the second column 32 is fixedly connected to the frame of the discharge conveyor belt 1. The two ends of the second crossbeam 31 are detachably connected to the corresponding second columns 32 by U-bolts 33. The second crossbeam 31 is made of angle steel, and bolt holes are opened on the vertical surface of the angle steel. The U-bolts 33 are fitted on the outside of the second columns 32. The threaded sections at both ends of the U-bolts 33 pass through the bolt holes on the second crossbeam 31 and are locked and fixed by nuts.

[0034] like Figure 6As shown, the moisture meter mounting bracket consists of a crossbeam 21, two columns 22, connecting angle steel 23, U-bolts 24, a mounting base 25, mounting bolts 26, a hydraulic cylinder 28, and a mounting plate 29. The lower end of the column 22 is fixedly connected to the frame of the discharge conveyor belt 1. The two ends of the crossbeam 21 are detachably connected to the corresponding columns 22 via connecting angle steel 23 and U-bolts 24. The two ends of the crossbeam 21 are respectively welded to the connecting angle steel 23, and the U-bolts 24 are sleeved on the outside of the columns 22. The threaded sections of the U-bolts 24 pass through the connecting angle steel 25, mounting bolts 26, hydraulic cylinder 28, and mounting plate 29. After bolting through the bolt holes on the angle steel 23, the mounting base 25 is secured with nuts. The mounting base 25 is an inverted T-shaped structure composed of a vertical plate and a horizontal plate. Bolt holes are formed on the vertical plate of the mounting base 25. The mounting bolts 26 are U-bolts, and both sets of mounting bolts 26 are fitted onto the outside of the crossbeam 21. The threaded ends of the mounting bolts 26 pass through the bolt holes on the mounting base 25 and are secured with nuts. The hydraulic cylinder 28 is installed at the bottom of the horizontal plate of the mounting base 25. The cylinder rod of the hydraulic cylinder 28 extends downwards and is detachably connected to the mounting plate 29. The moisture meter 27 is installed at the bottom of the mounting plate 29. Figure 5 , Figure 7 As shown, a rangefinder 4 is installed in the middle of the crossbeam 31 of the flat plate mounting bracket. The rangefinder 4 and the hydraulic cylinder 28 are interlocked and controlled by the control system.

[0035] The control system is a PLC controller.

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

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

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

[0039] The online moisture detection device for sintered mixtures described in this utility model allows for more convenient adjustment of the installation angle and position (including height and horizontal position) of the moisture meter, and enables online disassembly and installation of the moisture meter. By installing a protective mechanism upstream of the moisture meter, interference or collision with the moisture meter can be prevented when the surface of the sintered mixture on the discharge conveyor suddenly increases.

[0040] The online moisture detection device for sintered mixtures of this utility model includes a moisture meter mounting unit 2 and a moisture meter protection unit 3. In the moisture meter mounting unit 1, U-bolts are used as connecting parts between the first column 22 and the first beam 21, and between the first beam 21 and the mounting base 25. The U-bolts allow for rapid adjustment of the angle and installation position of the moisture meter 27. In the moisture meter protection unit 3, U-bolts are also used as connecting parts between the second column 32 and the second beam 31. The U-bolts allow for rapid adjustment of the installation position of the flat plate 34 (and the rangefinder 4).

[0041] In the moisture meter mounting unit 2, the two ends of the crossbeam 21 are connected to the column 22 via U-bolts 24. The U-bolts 24 allow for convenient adjustment of the height of the crossbeam 21 from the surface of the discharge conveyor belt 1 (i.e., the height from the surface of the sintered mixture), and also allow the crossbeam 21 to be easily removed from the column 22 for maintenance. The mounting base 25 is also connected to the crossbeam 21 using U-bolts (mounting bolts 26). These U-bolts allow for easy adjustment of the installation angle and longitudinal position of the moisture meter 27 along the crossbeam 21, and also allow for easy disassembly for debugging and maintenance. This solves the previous problem of not being able to disassemble and debug the moisture meter during the operation of the discharge conveyor belt, ensuring the continuity and timeliness of the moisture meter measurement, and enabling more accurate control of the moisture content in the sintered mixture.

[0042] Moisture meter protection unit 3 is installed at a distance upstream of 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 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 be slightly lower than the bottom surface of the moisture meter 27 when it is at its highest position. When the height of the sintered mixture surface is higher than the height of the flat plate 34, the flat plate 34 limits the height of the material surface to prevent the sintered mixture from directly contacting the moisture meter 27.)

[0043] The installation process of the online moisture detection device for sintered mixtures described in this utility model is as follows:

[0044] Step 1: First, weld the base plate 1 to the bottom of the column 22 of the moisture meter installation unit 1. Then, weld and fix the base plate 1 to the longitudinal beam of the discharge belt conveyor 1 downstream of the sintering material mixer discharge point. The column 22 is in a vertical state after welding.

[0045] Step 2: Weld connecting angle steel 23 to both ends of the crossbeam 21. Make bolt holes on the connecting angle steel 23 on both sides of the crossbeam 21. Use U-bolts 24 to connect the connecting angle steel 23 to the column 22, so that the crossbeam 21 is horizontally fixed above the belt surface of the discharge conveyor 1. Use U-bolts (mounting bolts 26) to install the mounting base 25 on the crossbeam 21. Then, suspend the moisture meter 27 on the mounting base 25 (or suspend the hydraulic cylinder 28 on the mounting base 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 conveyor 1.

[0046] Step 3: Weld a base plate 2 to the bottom of the second column 32 of the moisture meter protection unit 3, and then weld and fix the base plate 2 to the longitudinal beam of the discharge conveyor 1 between the feeding point of the sintering material mixer and the moisture meter installation unit 2. The welded second column 32 is in a vertical state.

[0047] Step 4: The crossbeam 2 31 is made of angle steel. Bolt holes are made at both ends of the crossbeam 2 31. U-bolts 2 33 are used to directly fix the crossbeam 2 31 to the column 2 32. The crossbeam 2 31 is horizontal after installation.

[0048] The adjustment method of the online moisture detection device for sintered mixtures described in this utility model is as follows: By loosening the nut that engages with the U-bolt 24, the connection between the crossbeam 21 and the column 22 can be loosened. At this time, the height of the crossbeam 21 can be adjusted up and down, or the crossbeam 21 together with the moisture meter 27 (or the crossbeam 21 together with the hydraulic cylinder 28 and the moisture meter 27) can be directly removed from the column 22, realizing online disassembly and maintenance of the moisture meter 27. By loosening the nut that engages with the mounting bolt 26, the connection between the crossbeam 21 and the mounting base 25 can be loosened. At this time, the mounting base 25 can be rotated or moved to adjust the installation angle and longitudinal position of the moisture meter 27 along the crossbeam 21. Similarly, the moisture meter 27 together with the mounting base 25 (or the moisture meter 27 together with the hydraulic cylinder 28 and the mounting base 25) can be directly removed from the crossbeam 21, realizing online disassembly and maintenance of the moisture meter 27.

[0049] By loosening the nut that engages with the U-bolt 33, the connection between the crossbeam 31 and the column 32 in the moisture meter protection unit 3 can be loosened, thereby adjusting the vertical height of the crossbeam 31 and adjusting the height of the flat plate 34 on the crossbeam 31 to be slightly lower than the height of the probe of the moisture meter 27.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
