Description

Technical Field

[0001] This application relates to the technical field of monitoring devices for cement production, specifically a monitoring device for cement production. Background Technology

[0002] In the clinker calcination process of cement production, it is necessary to observe the flame pattern and clinker calcination status inside the rotary kiln in real time. Currently, retractable high-temperature monitoring probes are commonly used. These probes are inserted into the kiln to capture images, replacing manual on-site observation. This reduces labor intensity and avoids safety risks caused by high temperatures and dust. Existing probes typically rely on cylinders or hydraulic telescopic rods to drive the entire probe into and out of the kiln. The front end is equipped with a lens and protective structure. For example, the high-temperature furnace with a monitoring device disclosed in prior art document CN205425871U uses a cylinder to drive the camera protective cover to move back and forth along the advance and retreat track. The front end is equipped with a high-temperature resistant baffle structure. This type of retractable monitoring structure is also widely used in the operational monitoring of cement rotary kilns and is a common technology in the field of high-temperature process monitoring.

[0003] However, existing monitoring probes of this type still have two obvious defects in actual use: First, the dust concentration inside the kiln is high, and the lens surface at the front end of the probe is easily covered with dust, which obstructs the view and affects the monitoring effect inside the kiln. Second, the probe's advance and retreat are entirely driven by the hydraulic telescopic rod. Once there is a power outage, gas outage, or hydraulic telescopic rod failure, the probe cannot be withdrawn from the kiln in time and is easily burned by high temperature. At the same time, when adjusting the probe's insertion depth, it is not possible to make fine adjustments manually, which is insufficient in terms of emergency response and usage flexibility.

[0004] Therefore, it is necessary to provide a monitoring device for cement production to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a monitoring device for cement production. Through the inclusion of a high-temperature resistant drive motor, shaft, vortex fan, and blowing holes, the device facilitates dust protection of the lens during monitoring, effectively extending the lens cleaning cycle, reducing downtime for cleaning, and ensuring the clarity and continuity of monitoring within the kiln. Furthermore, the inclusion of a pull handle, slider, lead screw, guide cavity shell, and U-shaped insert plate facilitates manual adjustment of the monitoring probe's insertion depth into the kiln in case of power failure or malfunction of the hydraulic telescopic rod, preventing the probe from being burned by high temperatures due to inability to retract in time. Simultaneously, it allows for daily manual fine-tuning, improving the device's emergency response capability and flexibility.

[0007] The technical solution adopted by this application to solve its technical problem is as follows: a monitoring device for cement production, including a high-temperature endoscopic monitoring probe, wherein multiple purge holes are equidistantly arranged circumferentially in the inner cavity of the high-temperature endoscopic monitoring probe, one end of the high-temperature endoscopic monitoring probe is provided with a 30-degree chamfer, the purge hole is located in the middle of the chamfer, a vortex cavity is provided at one end of the high-temperature endoscopic monitoring probe, a vortex fan is rotatably connected in the vortex cavity, a sealing threaded cover is provided at one end of the vortex cavity, the sealing threaded cover is threadedly connected to one end of the high-temperature endoscopic monitoring probe, a telescopic rod is fixedly fixed at the middle of the end of the sealing threaded cover away from the high-temperature endoscopic monitoring probe, a shaft is embedded in the inner side of the telescopic rod, the end of the shaft facing the vortex fan is fixedly connected to the middle of the vortex fan, a high-temperature resistant drive motor is provided at the end of the shaft away from the vortex fan, the output end of the high-temperature resistant drive motor is drivenly connected to one end of the shaft, and the purge hole communicates with the vortex cavity.

[0008] Furthermore, a protective column tube is provided on the outer side of one end of the telescopic rod, and a limit plate is fixed to one end of the telescopic rod. The end of the telescopic rod with the limit plate fixed is embedded in the protective column tube. The telescopic rod and the protective column tube are slidably connected. A clamping arc plate is clamped on the outer side of one end of the protective column tube. A guide cavity shell is fixed in the middle of one end of the clamping arc plate. A slider is embedded in the inner side of the guide cavity shell. A lead screw passes through the middle of the slider. One end of the lead screw is rotatably connected to the middle of one end of the guide cavity shell. The other end of the lead screw is connected through the end of the protective column tube away from the sealing threaded cover. The threaded drive of the lead screw drives the slider to slide and adjust its position in the guide cavity shell.

[0009] Furthermore, a fixing bolt is threaded through one end of the top of the protective column tube, and the fixing bolt abuts against the end face of the top of the telescopic rod after being tightened.

[0010] Furthermore, a hydraulic telescopic rod is installed at the end of the protective column tube away from the sealing threaded cover. The telescopic end of the hydraulic telescopic rod passes through the protective column tube and is fixedly connected to the housing of the high-temperature resistant drive motor by bolts. The front end face of the housing of the high-temperature resistant drive motor is fixedly connected to the end of the telescopic rod by threads. The slider is clamped to the side wall of the telescopic rod by clamps and locked by pins.

[0011] Furthermore, the slider is provided with a clamping mechanism, and an operation port is provided on the guide cavity shell at the initial position of the slider. A pull handle is provided on the end face of the slider facing the operation port, and a pullable clamping pin plate is inserted into the inner side of the pull handle.

[0012] Furthermore, the clamp pin plate consists of a middle pull rod and U-shaped insert plates fixed at both ends. The slider has a pull-out cavity for inserting the U-shaped insert plate. When the U-shaped insert plate is fully inserted into the pull-out cavity, one end of the U-shaped insert plate engages with the pin groove at one end of the telescopic rod. The limiting plate is embedded between the two U-shaped insert plates.

[0013] Furthermore, a non-slip, high-temperature resistant knob is fixed at one end of the lead screw that passes through the protective column tube.

[0014] The beneficial effects of this application are: 1. The cement production monitoring device provided in this application, through the setting of a high-temperature resistant drive motor, shaft, vortex fan and purging hole, when the high-temperature endoscopic monitoring probe is inserted into the rotary kiln, the high-temperature resistant drive motor drives the shaft to rotate, the rotating shaft drives the vortex fan to rotate in the vortex chamber, the airflow generated by the rotation of the vortex fan enters the purging hole, and the airflow is blown out circumferentially through a chamfered angle. When the airflow is blown out at a specific angle, it will blow the dust near the high-temperature endoscopic monitoring probe away from the direction of the high-temperature endoscopic monitoring probe. When the high-temperature endoscopic monitoring probe is withdrawn from the rotary kiln, the airflow in the purging hole will also dissipate the temperature emitted by the high-temperature endoscopic monitoring probe, which plays a role in facilitating dust blowing and protection of the lens during the monitoring process, effectively extending the lens cleaning cycle, reducing the number of downtime cleaning, and ensuring the clarity and continuity of the monitoring inside the kiln.

[0015] 2. The monitoring device for cement production provided in this application, through the setting of a pull handle, slider, lead screw, guide cavity shell, and U-shaped insert plate, allows the hydraulic telescopic rod to extend towards the protective column tube during normal operation. This drives the high-temperature resistant drive motor and the telescopic rod to slide along the inner wall of the protective column tube towards the sealing threaded cover. This, in turn, causes the shaft embedded in the telescopic rod, the sealing threaded cover fixed at one end of the telescopic rod, and the high-temperature endoscopic monitoring probe threaded to one end of the sealing threaded cover to extend into the rotary kiln. When the hydraulic telescopic rod is de-energized or malfunctions, the operator uses a tool to apply a pushing force towards the slider through the operating port. The pull handle drives the U-shaped insert plate along... The slide plate moves from the pull-out cavity towards the protective column tube. When the U-shaped insert plate is fully inserted into the pull-out cavity, one end of the U-shaped insert plate will be inserted into the pin slots set at both ends of the limiting plate. Then, by rotating the screw through the anti-slip and high-temperature resistant knob, the screw thread drives the slider to slide along the guide cavity shell towards the sealing thread cover. When the slider slides, it will drive the telescopic rod to slide along the protective column tube towards the sealing thread cover through the U-shaped insert plate. This facilitates manual adjustment of the depth of the monitoring probe in the kiln when the hydraulic telescopic rod is powered off or malfunctions, preventing the probe from being burned by high temperature due to failure to retract in time. At the same time, it can realize daily manual fine adjustment, improving the emergency response and flexibility of the device.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] like Figure 1-6As shown, this application provides a monitoring device for cement production, including a high-temperature endoscopic monitoring probe 1. Multiple purge holes 9 are equidistantly spaced circumferentially within the inner cavity of the high-temperature endoscopic monitoring probe 1. One end of the high-temperature endoscopic monitoring probe 1 has a 30-degree chamfer, with the purge holes 9 located in the middle of the chamfer. A vortex chamber is formed at one end of the high-temperature endoscopic monitoring probe 1, and a vortex fan 17 is rotatably connected within the vortex chamber. A sealing threaded cap 2 is provided at one end of the vortex chamber, and the sealing threaded cap 2 is threadedly connected to one end of the high-temperature endoscopic monitoring probe 1. A telescopic rod 3 is fixed to the middle of the end of the sealing threaded cap 2 away from the high-temperature endoscopic monitoring probe 1. A shaft 16 is embedded inside the telescopic rod 3. The end of the shaft 16 facing the vortex fan 17 is fixedly connected to the middle of the vortex fan 17. A high-temperature resistant drive motor 15 is provided at the end of the shaft 16 away from the vortex fan 17, and the output end of the high-temperature resistant drive motor 15 is drively connected to one end of the shaft 16. The purge holes 9 communicate with the vortex chamber.

[0022] In this embodiment, when the high-temperature endoscopic monitoring probe 1 is inserted into the rotary kiln, the high-temperature drive motor 15 drives the shaft 16 to rotate. The rotating shaft 16 drives the swirl fan 17 to rotate in the swirl chamber. The airflow generated by the rotation of the swirl fan 17 enters the purge hole 9. The airflow is blown out at a chamfered angle. When the airflow blows out at a specific angle, it blows the dust near the high-temperature endoscopic monitoring probe 1 away from the direction of the high-temperature endoscopic monitoring probe 1. When the high-temperature endoscopic monitoring probe 1 is pulled out of the rotary kiln, the airflow will dissipate the temperature emitted by the high-temperature endoscopic monitoring probe 1 during the flow of the airflow in the purge hole 9.

[0023] When the vortex fan 17 needs to be disassembled and replaced, simply rotate the sealing thread cover 2 to remove it from one end of the high-temperature endoscopic monitoring probe 1, and the vortex fan 17 can be taken out from the blocked vortex cavity for replacement. After replacement, it can be reinstalled.

[0024] It should be noted that, like the prior art, this application is installed at the observation hole on the wall of the rotary kiln, and the protective column tube 7 serves as the main installation body of the entire device.

[0025] like Figures 1 to 6As shown, a protective column tube 7 is provided on the outer side of one end of the telescopic rod 3. A limit plate is fixed to one end of the telescopic rod 3, and the end of the telescopic rod 3 with the fixed limit plate is embedded in the protective column tube 7. The telescopic rod 3 and the protective column tube 7 are slidably connected. A clamping arc plate 6 is clamped on the outer side of one end of the protective column tube 7. A guide cavity shell 5 is fixed in the middle of one end of the clamping arc plate 6. A slider 13 is embedded in the inner side of the guide cavity shell 5. A lead screw 14 passes through the middle of the slider 13. One end of the lead screw 14 is rotatably connected to the middle of one end of the guide cavity shell 5. The other end of the lead screw 14 is connected through the end of the protective column tube 7 away from the sealing threaded cover 2. The screw 14 drives the slider 13 to slide and adjust its position in the guide cavity shell 5. A fixing bolt 4 is threaded through one end of the top of the protective column tube 7. After the fixing bolt 4 is tightened, it abuts against the end face of the top of the telescopic rod 3. A hydraulic telescopic rod 8 is installed at the end of the protective column tube 7 away from the sealing threaded cover 2. The telescopic end of the telescopic rod 8 passes through the protective column tube 7 and is fixedly connected to the housing of the high-temperature resistant drive motor 15 by bolts. The front end face of the housing of the high-temperature resistant drive motor 15 is fixedly connected to the end of the telescopic rod 3 by threads. The slider 13 is clamped to the side wall of the telescopic rod 3 by clamps and locked by pins. The slider 13 is provided with a clamp mechanism. An operation port 10 is opened on the guide cavity shell 5 at the initial position of the slider 13. A pull handle 11 is opened on the end face of the slider 13 facing the operation port 10. The inner side of the pull handle 11 has a clamp pin plate 12 for pulling the pin. The clamp pin plate 12 is composed of a middle pull rod and U-shaped inserts fixed at both ends. The outer side of the U-shaped insert is provided with a pull cavity. When the U-shaped insert is fully inserted into the pull cavity, one end of it engages with the pin groove opened at one end of the telescopic rod 3. The limiting plate is embedded between the two U-shaped inserts. The end of the screw rod 14 that passes through the protective column tube 7 is fixed with an anti-slip high-temperature resistant knob.

[0026] In this embodiment, during normal power-on monitoring, the hydraulic telescopic rod 8 extends towards the protective column tube 7, which drives the high-temperature drive motor 15 and the telescopic rod 3 to slide along the inner wall of the protective column tube 7 towards the sealing threaded cover 2. This causes the shaft 16 embedded in the telescopic rod 3, the sealing threaded cover 2 fixed at one end of the telescopic rod 3, and the high-temperature endoscopic monitoring probe 1 threadedly connected to one end of the sealing threaded cover 2 to extend into the rotary kiln. When the hydraulic telescopic rod 8 is de-energized, the operator uses a tool to apply a pushing force towards the slider 13 to the pull handle 11 through the operating port 10. The pull handle 11 drives the U-shaped insert plate along... The pull-out cavity slides towards the protective column tube 7. When the U-shaped insert plate is fully inserted into the pull-out cavity, one end of the U-shaped insert plate will simultaneously be inserted into the pin slots at both ends of the limiting plate fixed on the protective column tube 7. Then, the screw 14 is rotated by the anti-slip and high-temperature resistant knob. The screw 14 drives the slider 13 to slide along the guide cavity shell 5 towards the sealing thread cover 2 through the threaded transmission of the screw 14. When the slider 13 slides, it will drive the telescopic rod 3 to slide along the protective column tube 7 towards the sealing thread cover 2 through the U-shaped insert plate. This makes it easy to manually adjust the depth of the monitoring probe into the kiln when the hydraulic telescopic rod is de-energized, which is beneficial to improving the effectiveness of the monitoring device.

[0027] Working principle: During normal power-on monitoring, the hydraulic telescopic rod 8 extends towards the protective column tube 7, which drives the high-temperature drive motor 15 and the telescopic rod 3 to slide along the inner wall of the protective column tube 7 towards the sealing threaded cover 2. This causes the shaft 16 embedded in the telescopic rod 3, the sealing threaded cover 2 fixed at one end of the telescopic rod 3, and the high-temperature endoscopic monitoring probe 1 threadedly connected to one end of the sealing threaded cover 2 to extend into the rotary kiln. When the hydraulic telescopic rod 8 is de-energized, the operator uses a tool to apply a pushing force towards the slider 13 to the pull handle 11 through the operating port 10. The pull handle 11 drives the U-shaped insert plate to slide along the pull-out cavity towards the protective column tube 7. When the U-shaped insert plate is fully inserted into the pull-out cavity, one end of the U-shaped insert plate will simultaneously engage with the pin slots at both ends of the limiting plate fixed on the protective column tube 7. Inside, the screw 14 is rotated by the anti-slip, high-temperature resistant knob. The screw 14 drives the slider 13 to slide along the guide cavity shell 5 toward the sealing thread cover 2. When the slider 13 slides, it drives the telescopic rod 3 to slide along the protective column tube 7 toward the sealing thread cover 2 through the U-shaped insert plate. When the high-temperature endoscopic monitoring probe 1 is inserted into the rotary kiln, the high-temperature resistant drive motor 15 drives the shaft 16 to rotate. The rotating shaft 16 drives the vortex fan 17 to rotate in the vortex cavity. The airflow generated by the rotation of the vortex fan 17 enters the blowing hole 9. The airflow is blown out at the angle set by the chamfer. When the airflow blows out at a specific angle, it will blow the dust near the high-temperature endoscopic monitoring probe 1 away from the direction of the high-temperature endoscopic monitoring probe 1, preventing the dust from adhering to the lens and affecting the monitoring effect.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
