Description

Technical Field

[0001] This utility model relates to the field of rotary kiln technology, and in particular to a rotary kiln idler roller displacement monitoring device. Background Technology

[0002] A rotary kiln is a piece of equipment used in the calcium carbide production process to produce limestone, primarily for calcining and roasting materials. The idler rollers, as key supporting components of the rotary kiln, bear the enormous weight of the kiln body and ensure its stable rotation. During long-term operation, due to factors such as thermal expansion and contraction of the kiln body, uneven material distribution, wear of the idler rollers themselves, and foundation settlement, the idler rollers may shift. If this is not detected and addressed promptly, it will lead to unstable operation of the rotary kiln, accelerated equipment wear, and even safety accidents, seriously affecting the continuity of production and product quality.

[0003] Currently, traditional methods for monitoring idler roller displacement have many limitations. Some factories rely on manual periodic inspections, observing the position of the idler rollers with the naked eye or measuring them with simple measuring tools. This method is inefficient, inaccurate, and difficult to capture instantaneous displacement changes of the idler rollers in a timely manner. Although some monitoring systems use sensor technology, the sensors are easily affected by the harsh environment around the rotary kiln, such as high temperature, dust, and vibration, resulting in inaccurate and unreliable monitoring data, which cannot meet the needs of modern industrial production for high-precision and real-time monitoring of rotary kilns. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a rotary kiln idler roller displacement monitoring device, thereby solving the problem that sensors are easily affected by the harsh environment surrounding the rotary kiln, leading to inaccurate monitoring data and low reliability. To achieve the above objective, the present utility model adopts the following technical solution:

[0005] The rotary kiln idler roller displacement monitoring device includes a support base and a shock absorption assembly disposed on the support base.

[0006] The housing is detachably mounted on the shock-absorbing component, and an installation channel is provided through the housing, with a cooling cavity surrounding the installation channel.

[0007] An end cap, detachably connected to the housing, is used to seal the cooling chamber;

[0008] A laser sensor is disposed on one side of the end cap and located within the mounting channel;

[0009] A lens mount is detachably mounted at the end of the housing away from the end cap, with a detection channel extending through its middle section, and a lens is disposed within the detection channel;

[0010] The dust removal assembly is disposed at the end of the lens mount away from the housing, corresponding to the lens.

[0011] Optionally, an inlet pipe and an outlet pipe are respectively provided through the end cover, and the inlet pipe and the outlet pipe are respectively connected to the cooling cavity.

[0012] Optionally, the end cap is provided with a mounting base on the side near the housing for mounting the laser sensor.

[0013] Optionally, the dust removal assembly includes an air blowing sleeve, which is disposed on the lens mount and communicates with the detection channel, and has multiple through holes on its periphery.

[0014] Optionally, the dust removal assembly further includes an outer jacket, which covers the outside of the air blowing sleeve and forms a cavity with the air blowing sleeve, and is detachably connected to the lens mount.

[0015] Optionally, the outer casing sidewall is provided with an air intake pipe, which is connected to the cavity.

[0016] Optionally, an annular groove is provided at the end of the air-blowing sleeve, and a sealing ring is provided in the annular groove.

[0017] Optionally, the end cap is provided with a mating seat on the side near the housing, and the mating seat is engaged with the side wall of the mounting channel.

[0018] Optionally, the docking seat is provided with a docking groove, and a sealing element is provided in the docking groove.

[0019] Optionally, the shock absorption assembly includes a shock absorption pad, and a plurality of spring columns are provided on one side of the shock absorption pad, and the plurality of spring columns are respectively connected to the support base.

[0020] Compared to existing technologies, the advantages of this invention are that by using the above-mentioned solution, a coolant is placed in the cooling chamber and circulated by an external water-cooled circulating pump to ensure that the laser sensor is not affected by the external high-temperature environment. The dust removal component intermittently blows air onto the lens to prevent dust from accumulating on the lens and affecting the detection effect. The shock absorption component can filter the vibration of the external environment and prevent the laser sensor from being affected by external vibration. The rotary kiln idler roller displacement detection device of this application has the effects of high temperature resistance, shock absorption, and prevention of dust contamination of the laser sensor. It effectively avoids external environmental interference, improves the detection accuracy and reliability of the laser sensor, and meets the needs of high-precision and real-time detection of rotary kilns.

[0032] like Figures 1-4 As shown, one embodiment of this utility model is a rotary kiln idler roller displacement monitoring device, which includes a support base 1, a shock-absorbing component 2, a housing 3, an end cover 4, a laser sensor 5, a lens mount 6, and a dust removal component 7. The support base 1 is vertically mounted on the external ground corresponding to the idler roller of the rotary kiln, and the shock-absorbing component 2 is mounted on the support base 1.

[0033] The housing 3 is detachably mounted on the shock absorption assembly 2, and a horizontally penetrating installation channel 31 is provided inside the housing, with a cooling cavity 32 arranged around the installation channel 31.

[0034] The end cap 4 is threaded to the left end of the housing 3 to seal the cooling chamber 32;

[0035] The laser sensor 5 is located on the right side of the end cap 4 and within the mounting channel 31;

[0036] The lens mount 6 is detachably mounted on the right end of the housing 3, with a detection channel 61 extending through its middle. A lens 62 is installed inside the detection channel 61, and the detection channel 61 is connected to the mounting channel 31.

[0037] The dust removal component 7, corresponding to the lens 62, is located on the right end of the lens mount 6 and is used for cleaning the lens.

[0038] When installing the above-mentioned detection device, the laser sensor 5 is installed on the right side of the end cover 4, and then the end cover 4 is connected to the housing 3. At this time, the laser sensor 5 is located in the installation channel 31. The lens mount 6 is installed on the right end of the housing 3, and then the housing 3 is installed on the shock absorption assembly 2.

[0039] When in use, this detection device aligns the working end of the laser sensor 5 with the radial or axial direction of the idler roller, allowing operators to detect subtle abnormal movements of the idler roller in real time. This enables measures to be taken at the initial stage of equipment failure, preventing serious consequences such as rotary kiln imbalance and cylinder deformation caused by the gradual accumulation of idler roller displacement, thus ensuring the long-term stable operation of the rotary kiln. The cooling chamber 32 is equipped with coolant, which is circulated by an external water-cooled circulating pump to ensure that the laser sensor 5 is not affected by the external high-temperature environment. The dust removal component 7 intermittently blows air onto the lens 62 to prevent dust accumulation on the lens 62, which would affect the detection effect. The vibration damping component 2 filters vibrations from the external environment, preventing the laser sensor 5 from being affected by external vibrations. In summary, this rotary kiln idler roller displacement detection device has the effects of high-temperature resistance, vibration damping, and prevention of dust contamination of the laser sensor 5, effectively avoiding external environmental interference, improving detection accuracy and the reliability of the laser sensor 5, and meeting the requirements for high-precision and real-time detection of the rotary kiln.

[0040] In one embodiment, such as Figure 5 As shown, an inlet pipe 41 and an outlet pipe 42 are respectively installed on the end cap 4. The inlet pipe 41 and the outlet pipe 42 are respectively connected to the cooling chamber 32. The output end of the external circulation pump is connected to the inlet pipe 41, and its input end is connected to the outlet pipe 42, so that the coolant in the cooling chamber 32 circulates and avoids the high temperature from affecting the laser sensor 5.

[0041] In one embodiment, such as Figure 5 As shown, a mounting base 43 is provided on the right side of the middle part of the end cover 4 for mounting the laser sensor 5. This allows the laser sensor 5 to be located exactly in the mounting channel 31 and not in contact with the housing 3, thus avoiding friction caused by external vibration.

[0042] In one embodiment, such as Figure 6 As shown, the dust removal assembly 7 includes an air blowing sleeve 71, which is mounted on the lens mount 6 and communicates with the detection channel 61. Multiple through holes 72 are provided on its periphery, allowing external high-pressure gas to enter the detection channel 61 through the multiple through holes 72 to remove dust from the outside of the lens 62.

[0043] In one embodiment, such as Figure 6 As shown, in order to allow the external high-pressure gas to pass evenly through the multiple through holes 72, the dust removal assembly 7 also includes an outer jacket 73. The outer jacket 73 covers the outside of the blowing sleeve 71 and forms a cavity with the blowing sleeve 71. It is detachably connected to the lens mount 6. After the external high-pressure gas enters the cavity, it blows air from the periphery of the lens 62 through the multiple through holes 72 to prevent dust from accumulating on the lens 62.

[0044] In one embodiment, such as Figure 6As shown, an air inlet pipe 730 is provided on the side wall of the outer jacket 73. The air inlet pipe 730 is connected to the cavity, and the air inlet pipe 730 is convenient for connecting to external high-pressure gas.

[0045] In one embodiment, such as Figure 6 As shown, an annular groove 711 is provided at the end of the air blowing sleeve 71, and a sealing ring is provided in the annular groove 711. The sealing ring is used to improve the sealing performance of the air blowing sleeve 71 and the outer sleeve 73 and prevent high-pressure gas from leaking out.

[0046] In one embodiment, such as Figure 5 As shown, a sealing seat 44 is provided on the side of the end cap 4 near the housing 3. The sealing seat 44 is fastened to the side wall of the mounting channel 31 to seal the cooling cavity 32 and prevent coolant from entering the mounting channel 31.

[0047] In one embodiment, such as Figure 5 As shown, a mating groove 441 is provided on the sealing seat 44, and a sealing element is provided in the mating groove 441. The sealing element can be sealant, silicone pad or sealing ring, which further improves the sealing performance of the end cover 4 and the sealing seat 44 and prevents coolant from entering the installation channel 31.

[0048] In one embodiment, such as Figure 1 As shown, the shock absorption assembly 2 includes a shock absorption pad 21. Multiple spring columns 22 are provided at the bottom of the shock absorption pad 21. The multiple spring columns 22 are respectively connected to the support base 1. The springs are used for bearing and low-frequency vibration reduction, while the shock absorption pad 21 is responsible for high-frequency energy dissipation. It can reduce the impact of external vibration on the laser sensor 5 in all directions. The shock absorption pad 21 is preferably made of rubber.

[0049] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
