Description

Technical Field

[0001] This utility model belongs to the field of monitoring technology for the calcium carbide turning status of calcium carbide furnaces, and particularly relates to a monitoring device for calcium carbide furnaces. Background Technology

[0002] The high dust concentration and temperature at the calcium carbide furnace production site make it difficult for traditional CCDs to penetrate the dust, and they are also easily damaged. Infrared thermal imaging monitoring systems, however, can penetrate the dust, providing a direct view of the overall temperature distribution and details within the furnace. Through this system, operators can monitor the combustion of the material in the furnace in real time, allowing for optimal material distribution; they can also monitor the heating of the three electrodes, whether the furnace lid is leaking, and the real-time monitoring of refractory material shedding from the furnace wall. This provides 24 / 7 automatic safety warnings, preventing furnace wall penetration and ensuring production safety, avoiding calcium carbide spillage caused by abnormal furnace temperatures.

[0003] Because of the high dust concentration at the calcium carbide furnace production site, the infrared probe is easily contaminated with dust, which hinders the accuracy of infrared reception. In addition, the monitoring probe is located at a high position, and maintenance requires climbing to a height. This makes it difficult to maintain the conventional monitoring probes used for monitoring abnormal calcium carbide turning conditions in calcium carbide furnaces.

[0004] Therefore, we propose a monitoring device for calcium carbide furnaces to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of difficult maintenance of conventional probes used for monitoring abnormal calcium carbide conditions in calcium carbide furnaces, and to propose a calcium carbide furnace monitoring device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A monitoring device for a calcium carbide furnace includes a guide column, a sliding sleeve slidably mounted on the guide column, an elastic sleeve mounted on the sliding sleeve, a screw mounted on the side of the elastic sleeve, and an infrared monitor rotatably mounted on the side of the elastic sleeve. A tension spring is provided between the guide column and the sliding sleeve, the upper end of the tension spring is fixedly connected to the guide column, and the lower end of the tension spring is fixedly connected to the sliding sleeve. A pull rope is fixedly connected to the lower part of the sliding sleeve. When the infrared monitor needs maintenance, the pull rope is pulled down, which acts downward on the sliding sleeve, causing the screw to pull down the elastic sleeve and the infrared monitor. The pull rope is then tied to the lower part of the guide column, and the screw is loosened, causing the screw to release the sliding sleeve and simultaneously releasing the infrared monitor from the elastic sleeve. After adjusting the direction of the infrared monitor and the elastic sleeve, the screw is tightened again to fix the direction of the elastic sleeve and the infrared monitor, reducing the maintenance difficulty of the infrared monitor.

[0007] Preferably, the guide post includes a column body with a limiting groove on its side and a rope anchor fixed to its lower part. The limiting groove restricts the rotation of the sliding sleeve, ensuring the stability of the sleeve's direction. When the pull rope is pulled down, it is anchored to the rope anchor, and the pull rope maintains the pulled-down state of the elastic sleeve.

[0008] Preferably, a mounting base is fixedly connected to the lower end of the column. Screws are passed through the mounting base to install the column on the ground.

[0009] Preferably, the sliding sleeve includes a sleeve body, and a slide bar is fixedly connected inside the sleeve body. The slide bar is slidably installed in a rotation limiting groove, and a retaining ring is fixedly connected to the lower part of the sleeve body. By using the retaining ring to stop the elastic sleeve from below, the elastic sleeve can be held on the sleeve body after the screw is loosened, ensuring the stability of the docking state of the sliding sleeve and the elastic sleeve.

[0010] Preferably, the elastic sleeve includes a spring and a sleeve body. A pressure block is slidably installed inside the spring and sleeve body. The spring and sleeve body are fitted onto the sleeve body, and the pressure block is in movable contact with the sleeve body. The screw is inserted through the side of the spring and sleeve body. After tightening the screw, the spring and sleeve body hug the sleeve body, causing the sleeve body to act on the pressure block. The pressure block then acts outward on the infrared monitor, causing the infrared monitor to be squeezed and fixed by the pressure block. This facilitates the simultaneous fixing of the horizontal angle of the elastic sleeve and the elevation angle of the infrared monitor.

[0011] Preferably, the infrared monitoring system includes a body, with a rotating base fixedly connected to its side. The rotating base is rotatably engaged inside the spring and sleeve, and the pressure block contacts the rotating base. The pressure block, pressed by the sleeve, acts on the rotating base, increasing the rotational resistance of the rotating base and achieving fixation.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. When the infrared monitor needs maintenance, pull down the pull rope. The pull rope will act downwards on the sliding sleeve, causing the screw to pull down the elastic sleeve and the infrared monitor. Tie the pull rope to the lower part of the guide column, loosen the screw to loosen the sliding sleeve, and at the same time, loosen the elastic sleeve from the infrared monitor. After adjusting the direction of the infrared monitor and the elastic sleeve, tighten the screw to fix the direction of the elastic sleeve and the infrared monitor, reducing the maintenance difficulty of the infrared monitor.

[0013] 2. By using a retaining ring to block the elastic sleeve, the elastic sleeve can remain on the sleeve body after the screw is loosened, ensuring the stability of the connection between the sliding sleeve and the elastic sleeve.

[0014] 3. After tightening the screws, the spring and the sleeve will hug the sleeve tightly, so that the sleeve acts on the pressure block. The pressure block then acts outward on the infrared monitor, so that the infrared monitor is squeezed and fixed by the pressure block. This makes it easy to fix the horizontal angle of the spring sleeve and the elevation angle of the infrared monitor at the same time. Attached Figure Description

[0018] like Figure 1 As shown, a monitoring device for an calcium carbide furnace includes a guide column 2, a sliding sleeve 3 slidably mounted on the guide column 2, an elastic sleeve 4 mounted on the sliding sleeve 3, a screw 1 mounted on the side of the elastic sleeve 4, and an infrared monitor 5 rotatably mounted on the side of the elastic sleeve 4. A tension spring 7 is provided between the guide column 2 and the sliding sleeve 3. The upper end of the tension spring 7 is fixedly connected to the guide column 2, and the lower end of the tension spring 7 is fixedly connected to the sliding sleeve 3. A pull rope 6 is fixedly connected to the lower part of the sliding sleeve 3. When the infrared monitor 5 needs maintenance, the pull rope 6 is pulled down, which acts downward on the sliding sleeve 3, causing the screw 1 to pull down the elastic sleeve 4 and the infrared monitor 5. The pull rope 6 is then tied to the lower part of the guide column 2. The screw 1 is then loosened, causing the screw 1 to release the sliding sleeve 3, and simultaneously causing the elastic sleeve 4 to release the infrared monitor 5. After adjusting the direction of the infrared monitor 5 and the elastic sleeve 4, the screw 1 is tightened again to fix the direction of the elastic sleeve 4 and the infrared monitor 5.

[0019] like Figure 1 and 2 As shown, the guide post 2 includes a post body 21, with a limited rotation groove 22 on the side of the post body 21, and a rope anchor 23 fixed to the lower part of the post body 21. The limited rotation groove 22 restricts the rotation of the sliding sleeve 3, ensuring the stability of the sliding sleeve 3. After the pull rope 6 is pulled down, it is tied to the rope anchor 23, and the pull rope 6 keeps the elastic sleeve 4 in the pulled-down state.

[0020] like Figure 2As shown, a mounting base 24 is fixedly connected to the lower end of the column 21. Screws are passed through the mounting base 24 to install it on the ground.

[0021] like Figure 1 , 2 As shown in Figure 3, the sliding sleeve 3 includes a sleeve body 31, and a slide bar 32 is fixedly connected inside the sleeve body 31. The slide bar 32 is slidably installed in the rotation limiting groove 22, and a retaining ring 33 is fixedly connected to the lower part of the sleeve body 31. The retaining ring 33 is used to stop the elastic sleeve 4, so that after the screw 1 is loosened, the elastic sleeve 4 can be held on the sleeve body 31.

[0022] like Figure 1 , 3 As shown in Figure 4, the elastic sleeve 4 includes an elastic body 41. A pressure block 42 is slidably installed inside the elastic body 41. The elastic body 41 is fitted onto the sleeve body 31, and the pressure block 42 is in movable contact with the sleeve body 31. A screw 1 is inserted through the side of the elastic body 41. After tightening the screw 1, the elastic body 41 hugs the sleeve body 31, causing the sleeve body 31 to act on the pressure block 42. Through the pressure block 42, it acts outward on the infrared monitor 5, causing the infrared monitor 5 to be pressed and fixed by the pressure block 42.

[0023] like Figure 1 , 3 As shown in Figures 4 and 5, the infrared monitoring unit 5 includes a body 51. A rotating base 52 is fixedly connected to the side of the body 51. The rotating base 52 is rotatably locked inside the spring and sleeve body 41, and the pressure block 42 contacts the rotating base 52. The pressure block 42 is squeezed by the sleeve body 31 and acts on the rotating base 52, increasing the rotational resistance of the rotating base 52 to achieve fixation.

[0024] Working principle: When the infrared monitor 5 needs maintenance, pull the pull rope 6 downwards. The pull rope 6 acts downwards on the sliding sleeve 3, causing the screw 1 to pull down the elastic sleeve 4 and the infrared monitor 5. Tie the pull rope 6 to the lower part of the guide post 2, loosen the screw 1, so that the screw 1 releases the sliding sleeve 3, and at the same time, the elastic sleeve 4 releases the infrared monitor 5. After adjusting the direction of the infrared monitor 5 and the elastic sleeve 4, tighten the screw 1 to fix the direction of the elastic sleeve 4 and the infrared monitor 5.
