Description

Technical Field

[0001] This application relates to the field of metal smelting, specifically to a rotary kiln for real-time monitoring of the working status of nickel alloy preparation. Background Technology

[0002] Nickel alloys are alloys composed of nickel as a base and other elements. They have wide applications in energy development, chemical industry, electronics, marine, aviation, and aerospace. Nickel is mainly found in various laterite nickel ores. The raw material, laterite nickel ore, is ground and mixed with carbonaceous materials and flux limestone, then continuously fed into a rotary kiln. After being heated at high temperatures within the kiln, the resulting molten material exits as a briquettes. The rotary kiln, resembling a rotating bed, is also called a rotary bed kiln. It mainly consists of a kiln head, kiln body, kiln tail, and support frame. Because the material is heated at high temperatures within the kiln, and the kiln body rotates continuously during this process, and the kiln body is tilted, the material is heated while moving from the feed inlet towards the kiln head under the driving force of rotation and the force of gravity, until it is discharged from the kiln head. Because it involves high-temperature heating and continuous slow rotation, the mechanical operating condition of the rotary kiln, as well as the insulation performance of the kiln body and the normality of the outer wall of the kiln, are very important for the normal operation of the rotary kiln. Furthermore, due to the large size of the rotary kiln, it is difficult to monitor it accurately in a timely manner through general manual inspections or ordinary video monitoring systems, and it is also impossible to achieve online real-time monitoring. Summary of the Invention

[0003] Purpose of the invention: This application aims to overcome the shortcomings of developing technology and provide a rotary kiln for real-time monitoring of the working status of nickel alloy preparation.

[0004] Technical solution: A rotary kiln for nickel alloy preparation includes a control unit, a kiln body, a kiln head, a kiln tail, a drive unit, two support units, and two monitoring units. The kiln body has a gear ring unit and two rotating rings. The drive unit includes a first mounting base, a first motor, and a drive gear driven by the first motor that meshes with the gear ring unit. The support unit includes a second mounting base and two guide rollers mounted on the second mounting base. The rotating rings are supported by the two guide rollers. One of the two monitoring units is located between the kiln head and one of the support units, and the other monitoring unit is located between the kiln tail and the other support unit. The monitoring unit includes an image acquisition unit. The kiln body has two circular identification marks, one of which is located between the kiln head and one of the rotating rings, and the other is located between the kiln tail and the other rotating ring. The circular identification marks have multiple strip-shaped identification marks distributed in a circular, equally spaced pattern.

[0005] Thus, through the monitoring unit, the status of the kiln body, especially the mechanical operating status, can be monitored in real time.

[0006] Furthermore, the two rotating rings are fixedly connected to the kiln body; each rotating ring is supported by two guide rollers.

[0007] Furthermore, the kiln head is equipped with a combustion device and a feed pipe; the kiln tail is equipped with an exhaust pipe and a feed pipe.

[0008] Furthermore, the length direction of the bar-shaped identification mark is parallel to the axial direction of the circular identification mark.

[0009] Furthermore, each circular identification mark has at least 20 bar identification marks.

[0010] This provides a better foundation for image recognition by identifying the markers, making it easier to calculate speeds and other parameters.

[0011] In some embodiments, the circular and bar identification marks are applied to the outer wall of the kiln body by means of paint.

[0012] In other embodiments, circular and bar identification marks can also be set using suitable methods such as paint or stickers.

[0013] Thus, the circular and bar identification marks provide the basis for identification, but have almost no physical thickness, avoiding inconvenience to the movement of the vibration detection unit and the temperature detection unit.

[0014] Of course, the image acquisition unit can also take pictures of the outer wall, and then judge the defects and damage of the outer wall of the kiln body based on the captured images.

[0015] Furthermore, the monitoring unit includes a base plate, on which a vibration detection unit, a temperature detection unit, and an image acquisition unit are mounted; the vibration detection unit includes a first base and a vibration sensor mounted on the first base, the detection head of the vibration sensor being able to abut against the outer wall of the kiln body; the temperature detection unit includes a second base, the top of the second base having a top groove and the top of the second base being able to abut against the outer wall of the kiln body, and a temperature sensor being installed in the top groove.

[0016] This allows the second support to abut against the outer wall of the kiln, making the temperature sensor's temperature detection more accurate. Since the kiln has excellent insulation properties, the temperature of the outer wall should not be very high in theory. If the temperature is abnormal, it indicates that the kiln may be damaged.

[0017] Furthermore, the monitoring unit includes a first mounting bracket and a second mounting bracket. A first rotating rod, a second rotating rod, and a strip slide rail are installed between the first and second mounting brackets. Both the first and second rotating rods have helical protrusions with opposite helical directions. Passive rollers are installed at both the first and second rotating rods. A drive rod is installed between the shaft of one of the guide rollers of the first mounting bracket and the corresponding support unit of the first mounting bracket. A drive roller that abuts against both passive rollers is installed at the drive rod. A slide block is installed at the strip slide rail. The slide block and the base plate are connected by multiple connecting springs. The base plate has a mounting groove. A second motor is installed at the mounting groove. The second motor drives a rotating arm. A toothed seat is installed at the end of the rotating arm. The toothed seat has multiple first meshing teeth above it that can engage with the helical protrusions of the first rotating rod, and multiple second meshing teeth below it that can engage with the helical protrusions of the second rotating rod.

[0018] The spring force pushes the base plate upwards, allowing the second seat of the temperature detection unit and the detection head of the vibration detection unit to abut against the outer wall of the kiln. However, this spring force is not very large; it is sufficient to ensure that the second seat and the detection head abut against the kiln.

[0019] Furthermore, a rotating arm mounting bracket is installed at the mounting groove, and a rotating arm shaft is fixedly connected to the rotating arm. Both ends of the rotating arm shaft pass through the rotating arm mounting bracket, and the second motor is connected to the rotating arm shaft to drive the rotating arm shaft to rotate.

[0020] Furthermore, bearings are installed at both ends of the rotating arm shaft and between the rotating arm mounting bracket.

[0021] The second motor drives the rotating arm shaft to rotate, and the rotating arm rotates synchronously with the rotating arm shaft. Due to the installation of the rotating arm mounting bracket, the rotation of the rotating arm is more stable.

[0022] Furthermore, one end of the strip rail is fixedly connected to the first mounting bracket, and the other end is fixedly connected to the second mounting bracket.

[0023] Furthermore, the second motor is mounted in the mounting groove via a motor mount; a limiting frame is also installed in the mounting groove, the limiting frame including a top plate, a bottom plate, and a connecting plate connecting the top plate and the bottom plate, the connecting plate having a through hole through which the rotating arm passes, a first spring connecting the top plate and the rotating arm, a second spring connecting the bottom plate and the rotating arm, two first limiting rods fixed at the top plate, the bottom end of the first limiting rods abutting against the rotating arm, and two second limiting rods fixed at the bottom plate, the top ends of the second limiting rods abutting against the rotating arm.

[0024] The first and second limiting rods restrict the range of rotation of the rotating arm, thus preventing damage caused by excessive engagement of the first and second meshing teeth and the helical protrusions at the first and second rotating rods. Engagement is sufficient only if the helical protrusions can drive the toothed seat to move; the first and second meshing teeth do not need to contact the surfaces of the first and second rotating rods.

[0025] Furthermore, a bearing is installed between one end of the first rotating rod and the first mounting bracket, and a bearing is installed between the other end of the first rotating rod and the second mounting bracket.

[0026] Furthermore, a bearing is installed between one end of the second rotating rod and the first mounting bracket, and a bearing is installed between the other end of the second rotating rod and the second mounting bracket.

[0027] Furthermore, a bearing is installed between one end of the drive rod and the first mounting bracket, and the other end is connected to the rotating shaft of the guide roller via a coupling.

[0028] This makes the rotation of the first and second rotating rods and the drive rod smoother.

[0029] Furthermore, a mounting plate is fixed to the end of the strip rail near the first mounting bracket, a laser rangefinder is mounted on the mounting plate, and a positioning plate is mounted on the base plate. The laser rangefinder is capable of measuring the distance between the laser rangefinder and the positioning plate.

[0030] Therefore, the laser rangefinder sensor, in conjunction with the positioning plate, makes distance detection more accurate.

[0031] Furthermore, a rotating arm limiting plate is installed at both the first mounting bracket and the second mounting bracket. The rotating arm limiting plate has a V-shaped groove and a recess connected to the V-shaped groove. When the rotating arm is located in the recess, the first meshing tooth does not mesh with the spiral protrusion at the first rotating rod, and the second meshing tooth does not mesh with the spiral protrusion at the second rotating rod.

[0032] Furthermore, an L-shaped rod is fixedly connected to the rotating arm limiting plate at the first mounting frame. The base plate has a wedge-shaped groove with an abutting inclined surface. The end of the L-shaped rod can abut against the abutting inclined surface, thereby causing the base plate to move downward, so that the detection head of the vibration detection unit and the top of the second seat of the temperature detection unit do not contact the kiln body.

[0033] Furthermore, the ends of the L-shaped rod, the first limiting rod, and the second limiting rod are all arc-shaped.

[0034] Furthermore, the second mounting bracket is fixedly connected to the second mounting seat of the support unit corresponding to the second mounting bracket.

[0035] Furthermore, the length of the strip rail is greater than or equal to 1 meter.

[0036] Beneficial effects: The rotary kiln of this application can be monitored at the kiln head and the kiln tail, thereby achieving overall monitoring of the kiln body by monitoring the mechanical and temperature conditions of the kiln body at both ends, thus achieving overall monitoring of the kiln body's condition.

[0037] The rotary kiln monitoring system of this application can realize reciprocating motion, thereby achieving real-time reciprocating motion and long-term monitoring. The power required for its reciprocating motion can be obtained from the rotary kiln's own power system without additional settings. Furthermore, by utilizing the rotary kiln's own power, online monitoring and the rotary kiln's motion can be synchronized to a certain extent.

[0038] The real-time monitoring system of this application can monitor a wide range of items and can simultaneously monitor multiple aspects such as temperature, vibration, and mechanical operating status.

[0039] The monitoring system described in this application has multiple safety features to prevent hardware damage that may result from software malfunctions. Attached Figure Description

[0057] The monitoring unit includes a first mounting bracket 3.1 and a second mounting bracket 3.2.

Both the first rotating rod 9.1 and the second rotating rod 9.2 have spiral protrusions with opposite spiral directions. Passive rollers 9.1.1 and 9.2.1 are installed at both the first rotating rod 9.1 and the second rotating rod 9.2. A drive rod 9.3 is installed between the rotating shaft of one of the guide rollers 1.9 of the support unit corresponding to the first mounting bracket 3.1 and the first mounting bracket 3.1.

A first spring 5.2.6 connects the base plate 5.2.2 and the rotating arm 5.2.9. A second spring 5.2.8 connects the base plate 5.2.2 and the rotating arm 5.2.9.

[0058] A rotating arm limiting plate 6 is installed at both the first mounting bracket 3.1 and the second mounting bracket 3.2. The rotating arm limiting plate 6 has a V-shaped groove 6.1 and a recess 6.2 connected to the V-shaped groove 6.1. When the rotating arm 5.2.9 is located in the recess 6.2, the first meshing tooth 5.10.1 does not mesh with the spiral protrusion at the first rotating rod 9.1, and the second meshing tooth 5.10.2 does not mesh with the spiral protrusion at the second rotating rod 9.2.

The ends of the L-shaped rod 7, the first limiting rod 5.2.5, and the second limiting rod 5.2.7 are all arc-shaped. The second mounting bracket 3.2 is fixedly connected to the second mounting seat of the support unit corresponding to the second mounting bracket 3.2. The length of the strip slide rail is greater than or equal to 1 meter.

[0059] The rotary kiln of this application, through the cooperation of a laser rangefinder and a positioning plate, can sense the position of the slide, thereby enabling more precise control of the slide, for example, in... Figure 1 The state shown and Figure 3 When the states shown are switched periodically, the position of the slide is sensed by a laser rangefinder, thereby controlling the second motor to switch between the two states of engagement with the first rotating rod and engagement with the second rotating rod.

[0060] Specifically, the rotary kiln of this application has multiple operating states:

[0061] 1) such as Figure 1 As shown, the slide is driven to translate by the first rotating rod. At this time, the slide moves from the direction of the first mounting frame to the direction of the second mounting frame. Since the first meshing tooth engages with the spiral protrusion of the first rotating rod, the above translation can be achieved. During the translation of the slide, the image acquisition unit can acquire images. The second seat of the temperature sensor abuts against the outer wall of the kiln body, so the temperature sensor can measure the temperature more accurately. The detection head of the vibration sensor abuts against the outer wall of the kiln body, so the detection of vibration signals can be more accurate.

[0062] 2) such as Figure 2As shown, at this point, driven by the second motor, the gear seat is positioned between the first and second rotating rods, and both the first and second meshing teeth are in a non-meshing state. Furthermore, due to the support of the first and second springs on the rotating arm, the position of the rotating arm is more stable. At this time, the slide stops below the circular identification mark, and the image acquisition unit can acquire the image of the bar identification mark to calculate the rotational speed. Of course, it's not necessary to stop at this position every time; it can proceed directly without stopping. Whether to stop for detection at this position is selected by the maintenance personnel through the control unit.

[0063] 3) such as Figure 3 As shown, the second rotating rod drives the slide to translate, and... Figure 1 The direction of movement is opposite, and the items and principles it detects are the same as... Figure 1 The state shown is similar.

[0064] 4) such as Figure 4 As shown, moving the slide block to one end of the L-shaped rod allows the vibration detection unit and temperature detection unit to disengage from the outer wall of the kiln under the contact of the L-shaped rod, thus stopping the monitoring unit. At this time, the second motor control gear seat is positioned between the first and second rotating rods, and both the first and second meshing teeth are in a non-meshing state. In actual use, it is not necessary to monitor the kiln's condition every moment. In practice, a reciprocating test once a day or every hour may suffice. During other periods when monitoring is not required, the kiln can be... Figure 4 As shown, at this time, both the second seat and the detection head of the vibration sensor are detached from contact with the outer wall of the kiln, thus avoiding excessive damage to the second seat and the detection head of the vibration sensor.

[0065] 5) such as Figure 5 As shown, in this state, when a software control error occurs, the rotating arm limit plate ensures that when the slide reaches the rotating arm limit plate, both the first and second meshing teeth disengage, preventing the slide from moving excessively to the end. During operation, based on the measurement signal from the laser rangefinder sensor, the control unit determines that after the slide reaches the designated position, the second motor changes the meshing state of the first and second meshing teeth, causing the slide to move in the opposite direction. Generally, it will not move to the end. Figure 5 The state shown is as described. However, if there is a software control error or a laser ranging error, even if the sliding seat moves too far, the toothed seat will disengage from the spiral protrusions of the first and second rotating rods due to the limiting plate of the rotating arm, thus causing the sliding seat to disengage from the drive and stop, preventing accidental drive damage to the monitoring unit. When the desired state is reached... Figure 5 After the status shown is reached, maintenance personnel need to debug the equipment and restore it to its initial state before performing the above monitoring operations.

[0066] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the scope defined by the claims.
