Description

Technical Field

[0001] This utility model relates to the field of coke oven temperature measurement technology, and more specifically to an intelligent vertical adjustment device for a temperature measuring tube at the center of coke cake in a coke oven. Background Technology

[0002] With the implementation of national carbon reduction policies and the increasing size of coke ovens, the height of the coke oven carbonization chamber has increased to 6-7.63 meters, and the length of the temperature measuring tube at the center of the coke cake has also increased accordingly to about 7.5 to 9 meters. However, the traditional tube insertion method for measuring the center temperature of the coke cake is facing increasing challenges. For example, when the temperature measuring tube is inserted into the upper part of the coal charging hole of the coal charging cover, even a slight radial deviation will amplify the deviation at the lower temperature measuring point of the carbonization chamber, resulting in inaccurate measurement results and possibly damaging the carbonization chamber wall, leading to safety hazards and maintenance costs.

[0003] A search revealed a patent with application number CN103776555A, which discloses a method for measuring the center temperature of coke cake in a coke oven. Specifically, a temperature measuring tube is inserted through an opening in the coke oven door, and a temperature measuring tube is also inserted into the coal charging cover on the top of the oven. This can shorten the length of the inserted steel tube and reduce the difficulty of insertion. However, in operation, it still relies on the verticality of the manually adjusted device, which is difficult to deal with the unevenness of the coke oven top surface, resulting in deviations in the measurement results.

[0006] 2. Technical Solution:

The top of the inner cylinder is provided with an overlap, and it is connected to the outer cylinder through the overlap. The inner cylinder can be replaced to suit temperature measuring tubes of different diameters.

[0019] A further technical solution involves the inner cylinder being constructed from two semi-cylindrical shells joined together, which facilitates the disassembly of the device. The inner cylinder can be disassembled first, followed by the remaining structure, making the process smoother.

[0020] A further technical solution involves using a straight-rod type ball joint bearing at the end of the ball joint for easy angle adjustment.

[0023] (1) The intelligent vertical adjustment device for the temperature measuring tube of the coke cake center temperature of this utility model ensures the verticality of the temperature measuring tube when measuring the temperature of the coke cake center temperature by automatically adjusting the verticality of the sleeve tube, so as to avoid the deviation of the temperature measuring tube insertion which may damage the carbonization chamber wall and cause inaccurate temperature measurement; the device first assembles the sleeve tube according to the diameter of the temperature measuring tube, installs it on the detachable platform support, and realizes the intelligent vertical adjustment of the sleeve tube by using the support leg lifting mechanism and angle sensor.

[0031] To further understand the contents of this utility model, a detailed description of the utility model is provided in conjunction with the accompanying drawings.

[0032] Example 1

[0033] The intelligent vertical adjustment device for the temperature measuring tube at the center of the coke oven cake in this embodiment, such as... Figure 1 , 2 As shown, it includes a controller 9, a limiting cylinder 1, an adjusting frame, a ball level sensor 8, and an angle sensor 10; the adjusting frame is sleeved on the cylinder body of the limiting cylinder 1; the angle sensor 10 is fixedly connected to the cylinder body of the limiting cylinder 1; the ball level sensor 8 and the angle sensor 10 are fixedly connected to the adjusting frame.

[0034] In this embodiment, the intelligent vertical adjustment device for the temperature measuring tube at the center of the coke oven cake is used. In specific use, the temperature measuring tube is inserted into the limiting cylinder 1. The adjusting frame, the ball level sensor 8, and the angle sensor 10 are all connected to the controller 9 via signals. After receiving the signals from the ball level sensor 8 and the angle sensor 10, the controller 9 controls the adjusting frame to adaptively adjust the horizontal deviation and vertical angle of the limiting cylinder 1. The controller 9 automatically adjusts the verticality of the limiting cylinder 1, thereby achieving the effect of accurately measuring the temperature by inserting the temperature measuring tube into the coke oven with better verticality.

[0035] Example 2

[0036] The intelligent vertical adjustment device for the temperature measuring tube at the center of coke oven cake in this embodiment has the same basic structure as in Embodiment 1, with the following differences or improvements: the controller 9 can specifically adopt an existing PLC controller 9; the adjustment frame is supported by adjustable legs, the number of adjustable legs being N, N≥3, forming a stable polygonal support for the limiting cylinder 1 to improve the stability of supporting the limiting cylinder 1, such as... Figure 3 , 4As shown, typically three adjustable legs are used for support, forming a triangular support for the limiting cylinder 1. The adjusting frame includes a chuck 2 sleeved on the cylinder body of the limiting cylinder 1. The driving component 3 of the chuck 2 clamps and releases the limiting cylinder 1. The chuck 2 is usually a three-jaw chuck 2. The driving component 3 is integrated into the chuck 2 and is usually a servo motor. The servo motor drives the three jaws 21 to clamp and release the limiting cylinder 1. The chuck 2 is fixedly connected to the corresponding adjustable legs through radial connecting rods 4. When there are three adjustable legs, there are also three radial connecting rods 4, corresponding one-to-one. A ball level sensor 8 is set on the surface of the chuck 2. The deviation angle of the limiting cylinder 1 relative to the vertical direction is adjusted by the coordination of the adjustable legs and the chuck 2. The adjustable support legs include a lower adjustable support leg 5 and an upper adjustable support leg 6 hinged to the top of the lower adjustable support leg 5; the two ends of the radial connecting rod 4 are fixedly connected to the outer side of the chuck 2 and the inner side of the lower adjustable support leg 5, respectively; the lower adjustable support leg 5 is supported on the base surface 20 on the side of the coal loading cover 12, the base surface 20 being the periphery of the opening of the coal loading cover 12; the top of the upper adjustable support leg 6 is fixedly connected to the cylinder body of the limiting cylinder 1. The lower adjustable support leg 5 is a first telescopic cylinder that extends downwards; the upper adjustable support leg 6 includes a support rod and a second telescopic cylinder, the top of the support rod is fixedly connected to the cylinder body of the limiting cylinder 1 through a ball hinge 7, and the bottom end of the support rod is hinged to the top of the first telescopic cylinder; so that the deviation angle of the limiting cylinder 1 relative to the vertical direction can be adjusted by extending and retracting the telescopic cylinder. A roller assembly is fixedly connected to the bottom of the lower adjustable support leg 5, wherein the roller is preferably a universal wheel 11, so that the adjustment action is flexible and mobile. The limiting cylinder 1 includes an outer cylinder 14 and an inner cylinder 13. The top of the inner cylinder 13 is provided with an overlap 15, which overlaps with the outer cylinder 14. The inner cylinder 13 can be replaced to accommodate temperature measuring tubes of different diameters. The inner cylinder 13 is composed of two half-cylinder shells spliced ​​together, which facilitates the disassembly of the device. The inner cylinder 13 can be disassembled first, followed by the remaining structure, which will make the disassembly smoother. The ball hinge 7 is a straight rod type ball head joint bearing, which rotates flexibly and facilitates angle adjustment.

[0037] The ball level sensor 8 and the lower adjusting leg 5 are connected to the controller 9 via wired or wireless signals, so that the three lower adjusting legs 5 cooperate with the leveling chuck 2; the angle sensor 10 and the upper adjusting leg 6 are connected to the controller 9 via wired or wireless signals, so that the three upper adjusting legs 6 cooperate with the adjustment of the deviation angle of the limiting cylinder 1 relative to the vertical direction. The radial connecting rod 4 and the lower adjusting leg 5 preferably adopt an existing detachable connection method. For example, a connecting rod head can be provided on the lower adjusting leg 5, and then the connecting rod head and the radial connecting rod 4 can be fixed by a connecting threaded sleeve.

[0038] In this embodiment, the intelligent vertical adjustment device is used by moving the device to the center of the opening of the coal loading cover 12 and aligning it visually to ensure that the temperature measuring tube can be smoothly inserted into the coal cake in the carbonization chamber through the opening of the coal loading cover 12 inside the sleeve tube.

[0039] The level sensor 8 first detects whether the chuck 2 is level. If it is not level, the controller 9 activates the three lower adjusting legs 5 according to the level deviation, specifically adjusting the chuck 2 by extending and retracting the first telescopic cylinder. Then, the angle sensor 10 detects whether the limiting cylinder 1 is in a vertical position and the vertical deviation angle. If it is not vertical, the controller 9 activates the three upper adjusting legs 6, specifically adjusting the limiting cylinder 1 by extending and retracting the second telescopic cylinder to correct its deviation and make it vertical. After the limiting cylinder 1 is adjusted to a vertical state, the controller 9 controls the servo motor to work, causing the chuck 2 to clamp the limiting cylinder 1 and position it.

[0040] Next, the prepared temperature measuring tube is inserted into the coal cake in the carbonization chamber through the limiting cylinder 1. The device can remain at this position (the temperature measuring tube needs to be relatively long) or it can be removed. During removal, when the temperature measuring tube is 10-20cm from the top of the limiting cylinder 1, the device can be directly lifted and removed from the top of the temperature measuring tube; alternatively, the ball hinge 7 can be disassembled, and then the limiting cylinder 1 can be removed first, followed by the remaining structure, which is safer and easier. The temperature measuring tube is then driven further into the coal cake until it is about 3-5cm above the coal hole cover, at which point a thermocouple is inserted to measure the center temperature of the coke cake. It should be noted that since the temperature measuring tube is already deeply inserted into the coal cake before removal, removal will not significantly affect the verticality of the temperature measuring tube's further insertion.

[0041] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention. The actual structure and manufacturing steps are not limited to these. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
