Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] The utility model provides Figures 1 to 3 A thermocouple for a roasting furnace flue shown in the figure comprises a device body 1, the device body 1 is mounted on a mounting seat 2, the mounting seat 2 is used to mount the thermocouple in the flue, the device body 1 comprises a temperature measuring main body rod 101 and a mounting end 102, the temperature measuring main body rod 101 extends outward from the mounting end 102, a cleaning ring 3 is sleeved on the outer side of the temperature measuring main body rod 101, the mounting end 102 is fixed on the outer side of the mounting seat 2, and a moving component for driving the cleaning ring 3 is arranged on the outer side of the cleaning ring 3;

[0024] The cleaning ring 3 on the outside of the temperature measuring main rod 101 is driven to move by the moving component, so that the dust attached to the outside of the temperature measuring main rod 101 can be scraped off to keep the surface of the temperature measuring main rod 101 clean, so that the thermocouple equipment body 1 can measure the temperature in the fire channel. During the movement of the cleaning ring 3, there is no need to remove the mounting base 2, so the operation is convenient and fast, and the thermocouple can be used continuously.

[0025] The moving component includes an internally threaded sleeve 4 that rotates inside the mounting seat 2 through a bearing. The temperature measuring main rod 101 is located on the inner side of the internally threaded sleeve 4 and is rotatably connected to the internally threaded sleeve 4 through a bearing. The outer side of the cleaning ring 3 is threadedly connected to the inner cavity of the internally threaded sleeve 4. One end of the internally threaded sleeve 4 passes through the mounting seat 2 and extends to a side away from the cleaning ring 3. The internally threaded sleeve 4 is threadedly connected to the cleaning ring 3 by rotating. After rotating the internally threaded sleeve 4, the cleaning ring 3 can be driven to move on the outside of the temperature measuring main rod 101.

[0026] A limiting rod 5 is fixed on the side of the mounting seat 2 away from the mounting end 102, and the limiting rod 5 extends to the interior of the internal threaded sleeve 4 and penetrates the cleaning ring 3 at one end away from the mounting seat 2. The setting of the limiting rod 5 facilitates the limiting of the cleaning ring 3 to prevent the cleaning ring 3 from rotating together with the internal threaded sleeve 4 after the cleaning ring 3 is threadedly connected to the internal threaded sleeve 4, so that the cleaning ring 3 cannot be moved on the outside of the temperature measuring main rod 101, and the dust attached to the surface of the temperature measuring main rod 101 cannot be removed.

[0027] A connecting block 6 is fixed to the outer side of the mounting end 102, and the side of the connecting block 6 away from the mounting end 102 is fixed to the outer side of the mounting seat 2. A swivel 7 is fixed to the end of the internally threaded sleeve 4, and the swivel 7 is located between the mounting end 102 and the mounting seat 2. The mounting end 102 is connected to the mounting seat 2 through the connecting block 6, and then the swivel 7 can rotate the internally threaded sleeve 4 from the outer side of the mounting seat 2, thereby driving the cleaning ring 3 to move.

[0028] A plurality of through grooves 8 are provided on the outer side of the internal threaded sleeve 4, and the width of the through grooves 8 is smaller than the diameter of the cleaning ring 3. The through grooves 8 are provided to prevent the internal threaded sleeve 4 from blocking the temperature measuring main rod 101 and affecting the temperature measuring main rod 101 in measuring the temperature inside the fire channel. The through grooves 8 connect the inside and outside of the internal threaded sleeve 4 to facilitate air flow.

[0029] When in use, the mounting seat 2 is installed on the fire channel through the screw thread 15, so that the temperature measuring main rod 101 passes through the inside of the fire channel. When dust adheres to the surface of the temperature measuring main rod 101, it is only necessary to rotate the rotating ring 7 to drive the internal threaded sleeve 4. Then the internal threaded sleeve 4 drives the cleaning ring 3 through the thread to move on the surface of the temperature measuring main rod 101 under the restriction of the limit rod 5 to remove the dust attached to the surface.
