Abstract
Description
Technical Field
[0001] This utility model relates to the field of kiln body monitoring technology, specifically a kiln body support roller displacement speed measuring device. Background Technology
[0002] The kiln body, also known as the rotary kiln cylinder, is where materials are continuously fed into the kiln during operation. Under the rotation of the kiln body, the materials are constantly tumbled, mixed, and propelled. This movement ensures that the materials are heated evenly and undergo sufficient chemical reactions or physical changes, thereby achieving the expected calcination or treatment effect.
[0003] In existing technologies, the rotational speed of the kiln body is measured by installing one or more sensors on the outer wall of the kiln body, and then fixing a detection element externally to receive the sensor signals. The rotational speed of the kiln body is then calculated based on the time required for the kiln body to complete one revolution. However, during long-term use, the kiln body is prone to deformation due to uneven heating, wear, and other reasons. This deformation causes the load applied to the support rollers during rotation to become uneven, easily leading to displacement between the kiln body and the support rollers. This causes a shift in the relative position of the sensors and detection element, and also changes the rotational speed of the kiln body. To monitor the changes in the rotational speed and displacement of the kiln body in a timely manner, a kiln body support roller displacement speed measuring device is needed to meet the requirements. Utility Model Content
[0004] The purpose of this invention is to provide a kiln body support roller displacement speed measuring device to solve the above-mentioned technical problems.
[0005] The technical solution adopted in this utility model is as follows: A kiln body support roller displacement speed measuring device includes a base and a kiln body. A plurality of support roller frames are mounted on the upper end of the base, and support rollers are rotatably mounted on the support roller frames. A rolling ring is fitted onto the kiln body, and the rolling ring contacts the support rollers. A movable frame is movably mounted on the upper end of the base, and a speed monitoring mechanism is mounted on the movable frame. An L-shaped bracket is installed between the support rollers and the movable frame, and a displacement monitoring mechanism is mounted on the L-shaped bracket. A linkage structure is connected to the displacement monitoring mechanism.
[0006] Preferably, the rotational speed monitoring mechanism includes two balls, both of which are movably installed inside the movable frame. The two balls are in contact with both sides of the rolling ring. A support plate is installed on one side of the movable frame, and an infrared rotational speed sensor is installed on the support plate. A detection element is installed on the outer surface of the kiln body, and the detection element corresponds to the infrared rotational speed sensor.
[0007] Preferably, two guide wheels are rotatably mounted at both ends of the movable frame, and two guide rails are mounted on the upper end of the base, with the two guide wheels on the same side movably mounted inside the same guide rail.
[0008] Preferably, the displacement monitoring mechanism includes a movable rod, which is movably mounted on one side of the L-shaped bracket. A contact displacement sensor is mounted on the movable rod, and the contact displacement sensor is located on one side of the movable frame.
[0009] As a further preferred embodiment, the movable rod has a sliding hole inside, and a guide rod is slidably installed in the sliding hole. The guide rod is installed on one side of the L-shaped bracket, and a baffle is installed at one end of the guide rod.
[0010] As a further preferred embodiment, both the contact displacement sensor and the infrared speed sensor are connected to a microprocessor.
[0011] As a further preferred embodiment, the linkage structure includes a reciprocating lead screw, which is installed on one side of the movable rod. A reciprocating threaded sleeve is threaded onto the reciprocating lead screw, and a driven gear is fixedly fitted onto the reciprocating threaded sleeve. Both the reciprocating threaded sleeve and the driven gear are rotatably installed inside the L-shaped bracket. A linkage gear ring is installed on one side of the support roller, and the linkage gear ring meshes with the driven gear.
[0012] As a further preferred embodiment, the L-shaped bracket has a limiting hole inside, and the reciprocating threaded sleeve is rotatably installed in the limiting hole.
[0013] The above technical solution has the following advantages or beneficial effects: (1) In this utility model, the detection element can be driven to move in a circular motion during the rotation of the kiln body, so that the detection element repeatedly passes through the sensing position of the infrared speed sensor. The infrared speed sensor can monitor the rotation speed of the kiln body according to the interval of repeated sensing. By monitoring the change of rotation speed, it can detect potential safety hazards in time, such as kiln overheating, material accumulation and other abnormalities. If the kiln body is displaced, the moving kiln body can drive the movable frame to move through the cooperation of the rolling ring and the rolling ball, thereby driving the infrared speed sensor to move accordingly, avoiding the displacement of the sensing position of the infrared speed sensor and the detection element, and ensuring the normal operation of the speed measurement work.
[0014] (2) While the support roller rotates with the kiln body, it can use the linkage gear ring and driven gear to make the movable rod move back and forth, thereby driving the contact displacement sensor to press against the surface of the movable frame. By repeatedly contacting and pressing the movable frame and detecting the resulting physical changes, the displacement or position is measured, thereby monitoring whether there is displacement between the kiln body and the support roller. In addition, the contact displacement sensor has the characteristic of being able to directly sense minute position changes, and its measurement accuracy and sensitivity are higher than those of non-contact sensors.

Figure 5 This is a schematic cross-sectional view of the movable frame structure of the kiln body support roller displacement speed measuring device proposed in this utility model. Please refer to... Figures 1 to 5 As shown, a preferred embodiment is illustrated; please refer to the illustration for details. Figure 1-5A preferred embodiment is shown, illustrating a kiln body support roller displacement speed measuring device, comprising a base 100 and a kiln body 101. A plurality of support roller frames 102 are mounted on the upper end of the base 100, and support rollers 103 are rotatably mounted on the support roller frames 102. A rolling ring 104 is fitted onto the kiln body 101, and the rolling ring 104 contacts the support rollers 103. A movable frame 200 is movably mounted on the upper end of the base 100, and a speed monitoring mechanism is mounted on the movable frame 200 to monitor the speed of the kiln body 101. An L-shaped bracket 300 is installed between the support rollers 103 and the movable frame 200, and a displacement monitoring mechanism is mounted on the L-shaped bracket 300 to monitor whether displacement occurs between the kiln body 101 and the support rollers 103. A linkage structure is connected to the displacement monitoring mechanism, which causes the displacement monitoring mechanism to move according to the rotation of the support rollers 103. The subject of this application is a kiln body support roller displacement speed measuring device, mainly used to measure the rotational speed of the kiln body 101 and whether there is any offset between the kiln body 101 and the support roller 103. Therefore, the subject of this application can also be a kiln body rotational speed measuring device and a kiln body displacement detection device relative to the support roller.
[0021] In this application, the lower end of the L-shaped bracket 300 is fixedly connected to the upper end of the base 100, which can be fixed by welding.
[0022] Furthermore, the speed monitoring mechanism includes two balls 201, both of which are movably mounted inside the movable frame 200. The two balls 201 contact the two sides of the rolling ring 104 respectively. A support plate 202 is mounted on one side of the movable frame 200, and an infrared speed sensor 203 is mounted on the support plate 202. A detection element 204 is mounted on the outer surface of the kiln body 101, corresponding to the infrared speed sensor 203. When the kiln body 101 rotates, it can drive the detection element 204 to move in a circular motion, thereby detecting the speed of the detection element 204. 04. As the kiln body 101 rotates, it repeatedly senses the infrared rotational speed sensor 203. The rotational speed of the kiln body 101 is monitored based on the interval of the repeated sensing. If the kiln body 101 shifts position during operation, the shifting kiln body 101 can drive the rolling ring 104 to move. This moving rolling ring 104 can then drive the movable frame 200 to move via the rolling ball 201. The continuously moving movable frame 200 can drive the infrared rotational speed sensor 203 to move, ensuring that the infrared rotational speed sensor 203 and the detection element 204 are always in a corresponding state. The detection element 204 is existing technology and mainly works in conjunction with the infrared rotational speed sensor 203. This detection element 204 is used to detect the infrared beam emitted by the infrared rotational speed sensor 203. The shape of the movable frame 200 can be seen in [reference needed]. Figure 2As shown, the upper end of the movable frame 200 has a slot, and the ball bearing 201 is disposed on the inner walls of both sides of the slot. Mounting grooves for mounting the ball bearing 201 can be provided on the inner walls of both sides of the slot. The ball bearing 201 is disposed in the mounting groove, and at least partially extends out of the mounting groove and is located at the slot opening, ensuring that the ball bearing 201 will not detach from the mounting groove even when it can rotate normally. The rolling ring 104 extends into the slot.
[0023] Furthermore, two guide wheels 205 are rotatably mounted at both ends of the movable frame 200, and two guide rails 206 are mounted on the upper end of the base 100. Two guide wheels 205 located on the same side are movably mounted inside the same guide rail 206. When the movable frame 200 moves, it drives the guide wheels 205 to roll within the guide rail 206, thereby restricting the direction of movement of the movable frame 200. The shape of the guide rail 206 can be found in [reference needed]. Figure 2 As shown, the guide rail 206 can be welded onto the upper end of the base 100. See also Figure 1 As shown, two guide rails 206 are provided between the two roller brackets 102 in the width direction. The guide rails 206 have grooves, and the guide wheels 205 can roll in the grooves. The guide wheels 205 are connected to the movable frame 200 by a rotating shaft.
[0024] Furthermore, the displacement monitoring mechanism includes a movable rod 301, which is movably mounted on one side of the L-shaped bracket 300. A contact displacement sensor 302 is mounted on the movable rod 301, located on one side of the movable frame 200. A sliding hole 307 is provided inside the movable rod 301, and a guide rod 308 is slidably mounted within the sliding hole 307. The guide rod 308 is mounted on one side of the L-shaped bracket 300, and a baffle 309 is mounted at one end of the guide rod 308. Both the contact displacement sensor 302 and the infrared speed sensor 203 are connected to a microprocessor. In this embodiment, the microprocessor is a prior art device used to read the detection signals from the contact displacement sensor 302 and the infrared speed sensor 203. The microprocessor can be connected to an external control device or alarm device. The detected rotational speed of the kiln body 101 can be displayed on the display of the external control device, which can be a PLC controller and a display connected to the PLC controller. When the kiln body 101 shifts relative to the support roller 103, an external alarm device will sound. (See also...) Figure 2 As shown, the movable rod 301 is arranged in a "Z" shape. The detection head of the contact displacement sensor 302 passes through the movable rod 301 and faces one side of the movable frame 200, so that when the movable rod 301 moves, it can drive the detection head of the contact displacement sensor 302 to touch the movable frame 200.
[0025] Furthermore, the linkage structure includes a reciprocating screw 303, which is installed on one side of the movable rod 301. A reciprocating threaded sleeve 304 is threaded onto the reciprocating screw 303, and a driven gear 305 is fixedly fitted onto the reciprocating threaded sleeve 304. Both the reciprocating threaded sleeve 304 and the driven gear 305 are rotatably mounted inside the L-shaped bracket 300. A linkage gear ring 306 is installed on one side of the support roller 103, and the linkage gear ring 306 meshes with the driven gear 305. A limiting rotation hole 310 is opened inside the L-shaped bracket 300, and the reciprocating threaded sleeve 304 is rotatably mounted in the limiting rotation hole 310. During the rotation of the kiln body 101, it can drive the support roller 103 to rotate through contact with it, thereby driving the linkage gear ring 306 to rotate. The rotating linkage gear ring 306 can drive the reciprocating screw 304 through meshing with the driven gear 305. The rotating sleeve 304 drives the reciprocating screw 303 to move horizontally back and forth. This causes the reciprocating screw 303, via the movable rod 301, to repeatedly press the detection head of the contact displacement sensor 302 against the movable frame 200. The contact displacement sensor 302 measures displacement or position by repeatedly making direct contact with the movable frame 200 and detecting the resulting physical changes such as resistance, capacitance, inductance, or piezoelectric effect. This allows monitoring of whether displacement has occurred between the kiln body 101 and the support roller 103. For example, if the resistance, capacitance, inductance, or piezoelectric effect generated by the contact displacement sensor 302 does not change, it indicates that the kiln body 101 has not moved relative to the support roller 103. If the resistance, capacitance, inductance, or piezoelectric effect generated by the contact displacement sensor 302 increases or decreases, it indicates that the kiln body 101 has moved relative to the support roller 103. The direction of displacement of the kiln body 101 is along its own axial direction. See, for example... Figure 1 As shown in the direction, when the kiln body 101 is displaced to the right, the resistance, capacitance, inductance or piezoelectric effect generated by the contact displacement sensor 302 decreases; if the kiln body 101 is displaced to the left, the resistance, capacitance, inductance or piezoelectric effect generated by the contact displacement sensor 302 increases.
[0026] In this embodiment, the kiln body 101 rotates forward and backward at a certain frequency. It does not rotate in one direction continuously, but switches between forward and reverse rotation. For example, the kiln body 101 will rotate backward after a certain number of rotations, and then rotate forward again after a certain number of rotations.
[0027] In this embodiment, the contact displacement sensor 302 is mainly used to detect whether the kiln body 101 is displaced relative to the support roller 103, rather than to detect the amount of displacement.
[0028] The working principle is as follows: When the kiln body 101 rotates, it drives the detection element 204 to move in a circular motion, causing the detection element 204 to repeatedly pass through the sensing position of the infrared speed sensor 203. As the detection element 204 rotates with the kiln body 101, it can repeatedly sense the infrared speed sensor 203. The rotational speed of the kiln body 101 is detected based on the interval of repeated sensing. If the position of the kiln body 101 shifts during operation, the kiln body 101 can drive the rolling ring 104 to move during the shift. When the rolling ring 104 rotates with the kiln body 101, it can drive the rolling ball 201 to move inside the movable frame 200 through contact with the rolling ball 201, thereby reducing the rolling speed. The friction between ball 201 and rolling ring 104 causes the moving rolling ring 104 to drive the movable frame 200 to move via ball 201. The continuously moving movable frame 200 can drive the infrared speed sensor 203 to move via support plate 202, ensuring that the infrared speed sensor 203 and the detection element 204 are always in a corresponding state, preventing the sensing position from shifting. Furthermore, during the rotation of the kiln body 101, it can drive the support roller 103 to rotate through contact with it, thereby driving the linkage gear ring 306 to rotate. The rotating linkage gear ring 306 can drive the reciprocating threaded sleeve 304 to rotate within the limiting rotation hole 310 through meshing with the driven gear 305. The reciprocating threaded sleeve 304 and the driven gear 305 work together to prevent them from falling out of the L-shaped bracket 300. The continuously rotating reciprocating threaded sleeve 304, through its threaded engagement with the reciprocating screw 303, drives the reciprocating screw 303 to move horizontally back and forth. This, in turn, causes the reciprocating screw 303 to drive the movable rod 301 to move back and forth. The movable rod 301 can slide on the guide rod 308 through the sliding hole 307, thus preventing the movable rod 301 from deviating during movement. The baffle 309 prevents the movable rod 301 from falling off the guide rod 308. The reciprocating movable rod 301 can drive... The detection head of the contact displacement sensor 302 reciprocates against the movable frame 200, causing the detection head of the contact displacement sensor 302 to extend and retract. The contact displacement sensor 302 has high measurement accuracy and sensitivity. It can measure displacement or position by repeatedly directly contacting the movable frame 200 and detecting the resulting physical changes such as resistance, capacitance, inductance, or piezoelectric effect, thereby monitoring whether displacement occurs between the kiln body 101 and the support roller 103. By connecting the infrared speed sensor 203 and the contact displacement sensor 302 to a microprocessor, the sensor signal can be read and used to control other equipment to trigger external alarm devices to issue an alarm. The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
