Description

Technical Field

[0001] The present invention relates to the technical field of temperature measurement of rotary kilns, and particularly to a temperature measurement device for the cylinder body of a lithium ore rotary kiln. Background Art

[0002] During the smelting process of lithium ore, as a key piece of equipment, the rotary kiln is widely used in the calcination and pyrolysis treatment of lithium ore. The temperature control of the cylinder body of the rotary kiln plays a crucial role in ensuring the quality, efficiency, and safety of lithium ore smelting. However, during the operation of the rotary kiln, due to factors such as uneven distribution of lithium ore materials, incomplete combustion, or equipment failures, local temperature abnormalities such as abnormal increases or decreases may occur on the surface of the cylinder body. If these temperature abnormalities cannot be detected and addressed in a timely manner, it will not only lead to a decline in the quality of lithium ore smelting but may also cause equipment damage or even safety accidents.

[0003] Traditional methods for measuring the temperature of the cylinder body of a rotary kiln mostly rely on manual hand-held temperature measurement instruments for point measurement or the use of temperature sensors at fixed positions for monitoring. These methods have obvious limitations: manual point measurement is inefficient and difficult to cover the entire surface of the cylinder body, easily missing temperature abnormal points; while the temperature sensors at fixed positions cannot monitor the temperature changes on the surface of the cylinder body in real time and have a slow response to dynamically changing temperature abnormalities.

[0004] To overcome the deficiencies of traditional temperature measurement methods and improve the real-time, accuracy, and comprehensiveness of temperature monitoring of the cylinder body of a rotary kiln, the industry urgently needs a temperature measurement device that can automatically, continuously, and comprehensively monitor the temperature changes on the surface of the cylinder body of a rotary kiln. This device should have the ability to quickly respond to temperature abnormalities, high-precision data acquisition, and adapt to the dynamic working environment of the rotary kiln, thereby ensuring the safe, efficient, and stable progress of the lithium ore smelting process.

The gas mixing component is arranged at the outer end of the surrounding ring.

[0007] Further, the driving component drives the rotary kiln cylinder to rotate through the driven ring, and the rotary kiln cylinder and the surrounding ring are concentrically arranged.

[0008] Further, the adjustment component includes a docking platform. A motor is arranged at the outer end of the docking platform, and a lead screw is connected to the output end of the motor. A displacement seat is arranged at the outer end of the lead screw. A U-shaped connecting seat is arranged at the outer end of the displacement seat, and a sliding seat is connected to the outer end of the U-shaped connecting seat.

[0009] Further, the motor drives the lead screw to rotate, and the rotation of the lead screw drives the displacement seat to move outwards.

[0010] Further, the displacement seat is fixedly connected to the U-shaped connecting seat and the sliding seat, and the sliding seat slides inside the sliding groove.

[0011] Further, the balls are in contact with the rotary kiln cylinder, and the rotary kiln cylinder is not in contact with the extension seat.

[0012] Further, three groups of electric control push rods are annularly distributed inside the surrounding ring, and the infrared temperature detector forms a fully enclosed structure through the surrounding ring and the barrier glass.

[0013] Further, the gas mixing component includes a gas mixing seat. Air inlet grooves are opened on both sides inside the gas mixing seat, and a filter screen is arranged in the middle section of the air inlet groove. A ventilation chamber is opened inside the gas mixing seat, and a return spring is arranged inside the ventilation chamber. A gravity push seat is connected to the outer end of the return spring. Ventilation grooves are opened at both ends of the bottom of the ventilation chamber, and a one-way air inlet valve is arranged at the end of the ventilation groove.

[0014] Further, the return spring is elastically connected to the gravity push seat, and the outer contour of the gravity push seat matches the contour of the ventilation chamber.

[0015] Further, the air inlet groove is connected to the ventilation groove through a ventilation chamber, and the ventilation groove is connected to the exhaust groove through a one-way air inlet valve.

[0016] The present invention provides a temperature measuring device for the barrel of a lithium ore rotary kiln, which has the following beneficial effects:

[0017] 1. The infrared temperature detector of the present invention continuously scans the surface of the barrel of the rotary kiln through a barrier glass, and real-time monitors local temperature anomalies. The barrier glass can effectively prevent dust adhesion and ensure the penetration of infrared signals. When a temperature anomaly is detected, the electric control push rod drives the fitting temperature detector to contact the abnormal area of the barrel. At this time, the surrounding ring rotates synchronously with the barrel of the rotary kiln to ensure that the fitting temperature detector collects high-precision data for the abnormal point. Through the coordinated cooperation of the rapid wide-area detection of the infrared temperature detector and the high-precision fixed-point measurement of the fitting temperature detector, both the monitoring range is expanded, and the detection efficiency and accuracy are improved.

[0018] 2. The present invention starts the motor to drive the screw rod to rotate, drives the displacement seat to move horizontally along the guide rod, and through the linkage of the U-shaped connecting seat and the sliding seat, the surrounding ring axially displaces in the chute to cover all the temperature measuring areas of the barrel of the rotary kiln; by periodically adjusting the position of the surrounding ring, the segmented and efficient temperature measurement of a large barrel is realized, and the problem of difficult overall monitoring due to the too large size of the barrel is solved.

[0019] 3. During the locking process of the electric control push rod and the barrel of the rotary kiln, the surrounding ring rotates synchronously with the barrel. When the gas mixing seat is inverted due to rotation, the gravity push block presses the return spring to connect the air inlet groove with the ventilation chamber. At this time, the low-temperature air filtered by the filter net enters the ventilation chamber to prevent external dust from invading the infrared temperature detector. When the gas mixing seat is upright, the gravity push block moves downward to stretch the return spring, so that the low-temperature gas in the ventilation chamber enters the inside of the surrounding ring through the ventilation groove and the exhaust groove to assist in heat dissipation. At the same time, the gas is discharged from the gap between the extension seat and the barrel to form a dust-blocking air curtain barrier, and the internal accumulated dust is synchronously carried out, thereby significantly improving the detection stability of the equipment through a dual dust-proof and temperature control mechanism.

Specific embodiments

[0028] Please refer to Figures 1 to 7 , the present invention provides a technical solution: a temperature measuring device for the barrel of a lithium ore rotary kiln, including a base 1, a temperature measuring component 7 and a gas mixing component 8. A driving component 2 is arranged at the outer end of the top of the base 1, and a rotary kiln barrel 3 is arranged at the outer end of the top of the driving component 2. A driven ring 4 is arranged at the outer end of the rotary kiln barrel 3. A position adjusting component 5 is arranged at the outer end of the top of the base 1. A guide rod 6 is arranged at the outer end of the base 1. A temperature measuring component 7 is arranged at the outer end of the position adjusting component 5. The temperature measuring component 7 includes a surrounding ring 701. Chutes 702 are opened at both outer ends of the surrounding ring 701. And balls 703 are arranged inside the surrounding ring 701. Extension seats 704 are arranged at both outer ends of the surrounding ring 701. And an electric control push rod 705 is arranged inside the surrounding ring 701. And a fitting temperature detector 706 is arranged inside the electric control push rod 705. An infrared temperature detector 707 is arranged inside the surrounding ring 701. And a barrier glass 708 is arranged inside the surrounding ring 701. An exhaust groove 709 is opened inside the surrounding ring 701. A gas mixing component 8 is arranged at the outer end of the surrounding ring 701.

[0029] The specific operation is as follows: the base 1 is fixed on the supporting structure of the rotary kiln, and the driving component 2 is ensured to be coaxially aligned with the driven ring 4. After the driving component 2 is coaxially aligned with the driven ring 4, the rotary kiln cylinder 3 is installed on the top of the driving component 2, and the rotary kiln cylinder 3 and the driven ring 4 are fixed. The driven ring 4 is driven to rotate by the driving component 2, and the rotary kiln cylinder 3 can be driven to rotate. The positioning component 5 is fixed to the base 1 through the docking platform 501, and is embedded in the surrounding ring 701 through the sliding seat 506. The surrounding ring 701 is connected with the slide groove 702, and the surrounding ring 701 is placed at the outer end of the rotary kiln cylinder 3 and concentric with it. At this point, the equipment is installed. After the rotary kiln cylinder 3 starts working, it will rotate at the outer end of the surrounding ring 701. The ball 703 rolls with the surface of the rotary kiln cylinder 3 to reduce friction resistance. At the same time, the gap between the surrounding ring 701 and the rotary kiln cylinder 3 is maintained through the extension seat 704 to avoid direct collision. The infrared thermometer 707 works and the infrared thermometer 707 can The surface of the rotary kiln cylinder 3 is continuously scanned through the barrier glass 708 to detect whether there is a local over-high or over-low temperature. The barrier glass 708 can prevent dust from adhering to the surface of the infrared thermometer 707 to ensure the penetration of the infrared signal. If the infrared thermometer 707 detects that the rotary kiln cylinder 3 has an abnormal temperature, the electric control push rod 705 pushes the fitting thermometer 706 to contact the abnormal temperature surface of the rotary kiln cylinder 3. At this time, the electric control push rod 705 is in contact with the rotary kiln cylinder 3. The contact is fixed, which enables the surrounding ring 701 to rotate synchronously with the rotary kiln shell 3, so that the fitted thermometer 706 can collect temperature data of abnormal points in real time. The detection accuracy of the fitted thermometer 706 is higher than that of the infrared thermometer 707, but the detection speed and range of the infrared thermometer 707 are wider than those of the fitted thermometer 706. By using the fitted thermometer 706 and the infrared thermometer 707 in combination, the detection efficiency and accuracy of the rotary kiln shell 3 can be greatly improved.

[0030] See also Figures 1 to 7, the driving component 2 drives the rotary kiln cylinder body 3 to rotate through the driven ring 4, and the rotary kiln cylinder body 3 and the surrounding ring 701 are concentrically arranged. The position adjustment component 5 includes a docking platform 501. An electric motor 502 is arranged at the outer end of the docking platform 501, and the output end of the electric motor 502 is connected to a lead screw 503. A displacement seat 504 is arranged at the outer end of the lead screw 503. A U-shaped connection seat 505 is arranged at the outer end of the displacement seat 504. A sliding seat 506 is connected to the outer end of the U-shaped connection seat 505. The electric motor 502 drives the lead screw 503 to rotate, and the rotation of the lead screw 503 drives the displacement seat 504 to move outwards. The displacement seat 504 is fixedly connected to the U-shaped connection seat 505 and the sliding seat 506, and the sliding seat 506 slides inside the chute 702. The ball 703 is in contact with the rotary kiln cylinder body 3, and the rotary kiln cylinder body 3 is not in contact with the extension seat 704. There are three groups of electric control push rods 705 annularly distributed inside the surrounding ring 701, and the infrared temperature detector 707 forms a fully enclosed structure through the surrounding ring 701 and the barrier glass 708. The gas mixing component 8 includes a gas mixing seat 801. Air inlet grooves 802 are opened on both sides inside the gas mixing seat 801, and a filter screen 803 is arranged in the middle section of the air inlet grooves 802. A ventilation chamber 804 is opened inside the gas mixing seat 801, and a return spring 805 is arranged inside the ventilation chamber 804. A gravity push seat 806 is connected to the outer end of the return spring 805. Ventilation grooves 807 are opened at both ends of the bottom of the ventilation chamber 804, and a one-way air inlet valve 808 is arranged at the end of the ventilation grooves 807. The return spring 805 is elastically connected to the gravity push seat 806, and the outer contour of the gravity push seat 806 matches the contour of the ventilation chamber 804. The air inlet grooves 802 are communicated with the ventilation grooves 807 through the ventilation chamber 804, and the ventilation grooves 807 are communicated with the exhaust groove 709 through the one-way air inlet valve 808;

[0031] The specific operation is as follows: after the temperature measurement of the rotary kiln cylinder 3 within the range of the surrounding ring 701 is completed, the electric control push rod 705 retreats to release the lock between the surrounding ring 701 and the rotary kiln cylinder 3, and the screw rod 503 is driven to rotate by the starting motor 502, which can drive the displacement seat 504 to move horizontally along the direction of the guide rod 6. Because the displacement seat 504 is connected with the slide groove 702 of the surrounding ring 701 through the U-shaped connection seat 505 and the sliding seat 506, the surrounding ring 701 can move in the axial position, and the surrounding ring 701 The displacement range covers the area of ​​the rotary kiln cylinder 3 that needs to be measured, which enables the equipment to periodically measure the temperature of the entire rotary kiln cylinder 3. By adopting the above method, the disadvantage of being unable to measure the temperature as a whole due to the rotary kiln cylinder 3 being too large can be avoided. In the process of locking the electric control push rod 705 with the rotary kiln cylinder 3, the surrounding ring 701 will rotate synchronously with the rotary kiln cylinder 3. When the surrounding ring 701 rotates to invert the mixing seat 801, the gravity push block 806 will squeeze the reset spring 805, which allows the air inlet groove 802 to be aligned with the ventilation The air mixing seat 801 is connected to the air mixing seat 801, and the low-temperature air from the outside can enter the ventilation chamber 804 through the air inlet groove 802. A filter 803 is arranged at the middle of the air inlet groove 802. The filter 803 can isolate the external dust, which can prevent the external dust from entering the surrounding ring 701 and affecting the normal temperature measurement of the infrared thermometer 707. When the mixing seat 801 rotates to the upright position, the gravity push block 806 will move downward with gravity and stretch the reset spring 805, so that the low-temperature gas sucked into the ventilation chamber 804 can pass through the ventilation groove 807. , the exhaust groove 709 enters into the interior of the surrounding ring 701, which can prevent the temperature inside the surrounding ring 701 from being too high and affecting the normal operation of its internal components. The gas entering into the surrounding ring 701 will be evenly discharged from the gap between the extension seat 704 and the rotary kiln cylinder 3, and form an air curtain barrier, which can block external dust from invading the temperature measurement area and assist in heat dissipation. In addition, if there is dust inside the surrounding ring 701, it can also be discharged together with the gas. Through the above operations, the detection stability of the equipment can be greatly improved.

[0032] In summary, when using the lithium ore rotary kiln cylinder temperature measuring device, first the base 1 is fixed on the supporting structure of the rotary kiln to ensure that the driving component 2 is coaxially aligned with the driven ring 4. After the driving component 2 is coaxially aligned with the driven ring 4, the rotary kiln cylinder 3 is installed on the top of the driving component 2, and the rotary kiln cylinder 3 and the driven ring 4 are fixed. The driven ring 4 is driven to rotate by the driving component 2, and the rotary drive of the rotary kiln cylinder 3 can be realized. The positioning component 5 is fixed to the base 1 through the docking platform 501, and is embedded in the slide groove 702 of the surrounding ring 701 through the sliding seat 506 to achieve connection with the surrounding ring 701, and the surrounding ring 701 is placed on the outer end of the rotary kiln cylinder 3 and concentric with it. At this point, the equipment is installed;

[0033] After the rotary kiln shell 3 starts to work, it will rotate at the outer end of the surrounding ring 701. The ball 703 makes rolling contact with the surface of the rotary kiln shell 3 to reduce the frictional resistance. At the same time, the extension seat 704 is used to maintain the gap between the surrounding ring 701 and the rotary kiln shell 3 to avoid direct collision. The infrared temperature detector 707 works. The infrared temperature detector 707 can continuously scan the surface of the rotary kiln shell 3 through the barrier glass 708 to detect whether there is a situation of too high or too low local temperature. The barrier glass 708 can prevent dust from adhering to the surface of the infrared temperature detector 707 and ensure the penetrability of the infrared signal. If the infrared temperature detector 707 detects that the rotary kiln shell 3 has an abnormal temperature situation, the electric control push rod 705 pushes the fitting temperature detector 706 to contact the abnormal temperature surface of the rotary kiln shell 3. At this time, since the electric control push rod 705 is in contact with and fixed to the rotary kiln shell 3, the surrounding ring 701 can rotate synchronously with the rotary kiln shell 3, which enables the fitting temperature detector 706 to collect temperature data of the abnormal point in real time. Because the detection accuracy of the fitting temperature detector 706 is higher than that of the infrared temperature detector 707, but the detection speed and range of the infrared temperature detector 707 are wider than those of the fitting temperature detector 706. By using the fitting temperature detector 706 and the infrared temperature detector 707 in combination, the detection efficiency and accuracy of the rotary kiln shell 3 can be greatly improved;

[0034] Then, after the temperature measurement of the rotary kiln shell 3 within the range of the surrounding ring 701 is completed, the electric control push rod 705 retracts to release the locking between the surrounding ring 701 and the rotary kiln shell 3. By starting the motor 502 to drive the screw rod 503 to rotate, the displacement seat 504 can be driven to move horizontally along the direction of the guide rod 6. Since the displacement seat 504 is connected to the chute 702 of the surrounding ring 701 through the U-shaped connection seat 505 and the sliding seat 506, the surrounding ring 701 can move axially. The displacement range of the surrounding ring 701 covers the area of the rotary kiln shell 3 that needs to be temperature measured, which enables the device to periodically measure the temperature of the entire rotary kiln shell 3. By adopting the above method, the drawback that the whole temperature measurement cannot be carried out due to the too large size of the rotary kiln shell 3 can be avoided;

[0035] Finally, during the locking process of the electric control push rod 705 and the rotary kiln shell 3, the surrounding ring 701 will rotate synchronously with the rotary kiln shell 3. When the surrounding ring 701 rotates and makes the gas mixing seat 801 inverted, the gravity push block 806 will squeeze the return spring 805, which enables the air inlet groove 802 to communicate with the ventilation chamber 804. At this time, the low-temperature air from the outside can enter the inside of the ventilation chamber 804 through the air inlet groove 802. A filter screen 803 is arranged in the middle of the air inlet groove 802, and the filter screen 803 can isolate external dust, which can prevent external dust from entering the inside of the surrounding ring 701 and affecting the normal temperature measurement of the infrared thermometer 707. When the gas mixing seat 801 rotates to the upright position, the gravity push block 806 will move downward with gravity and stretch the return spring 805, which enables the low-temperature gas inhaled inside the ventilation chamber 804 to enter the inside of the surrounding ring 701 through the ventilation groove 807 and the exhaust groove 709. This can prevent the temperature inside the surrounding ring 701 from being too high and affecting the normal operation of the components inside it. The gas that enters the inside of the surrounding ring 701 will be evenly discharged from the gap between the extension seat 704 and the rotary kiln shell 3 and form an air curtain barrier, which can block the intrusion of external dust into the temperature measurement area and assist in heat dissipation. In addition, if there is dust inside the surrounding ring 701, it can also be discharged together with the gas. Through the above operations, the detection stability of the equipment can be greatly improved.
