Description

Technical field:

[0001] The utility model relates to the field of temperature measurement, in particular to a device for measuring the temperature of a furnace top space of a 6.78-meter coke oven. Background technology:

[0002] During the coking production process, to measure the temperature of the top space of the 6.78-meter coking oven, it is necessary to place the special measurement furnace cover on the measuring furnace in advance. When placing it, two people lift the water-sealed furnace cover and replace it with the special measurement cover. During the replacement of the furnace cover, a large amount of air enters the carbonization chamber, affecting the quality of the coke. After the measurement is completed, the special furnace cover is replaced with the original water-sealed furnace cover, which is time-consuming and labor-intensive, and the operation time is long. In addition, there is a risk of burns when replacing the furnace cover as it is close to the furnace mouth. There is also a risk of falling off into the furnace mouth during the lifting process.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a device for measuring the temperature of the furnace top space of a 6.78-meter coke oven includes a water seal cover 1, and also includes a nut 2, a bolt 3 and a thermocouple 4. A through hole 5 is provided on the top of the water seal cover 1. The through hole 5 in this embodiment has a diameter of 5 cm. A nut 2 is fixed to the top of the through hole 5. The bolt 3 is movably screwed in the nut 2. The bolt 3 in this embodiment can be replaced with a lifting eye screw. When temperature detection is not performed, the bolt 3 is screwed in the nut 2, and the bottom of the bolt 3 is simultaneously extended into the through hole 5 to block the through hole 5; the thermocouple 4 movably passes through the through hole 5. When the thermocouple 4 needs to be used to measure the furnace top temperature, the bolt 3 is taken out of the nut 2, and the thermocouple 4 is passed through the water seal cover 1 along the nut 2 and the through hole 5, and extended to the furnace top.

[0019] The bracket 6 also includes two "convex" shaped vertical plates 7 and an "H" shaped horizontal plate 8. The two vertical plates 7 are respectively arranged on both sides of the nut 2, and the bottom of the vertical plates 7 is fixed to the water seal cover 1. The "H" shaped horizontal plate 8 has concave notches at both ends. One end of the horizontal plate 8 is rotatably connected to the top of one vertical plate 7. The rotatable connection is achieved by using a rotating shaft passing through both sides of the end notch of the horizontal plate 8 and the top of the vertical plate 7. The other end of the horizontal plate 8 is movably placed on the top of another vertical plate 7.

[0020] A circular hole 9 is provided in the middle of the horizontal plate 8 corresponding to the center of the nut 2, and two relatively sliding limit blocks 10 are symmetrically provided in the circular hole 9. When using the thermocouple 4 to measure the furnace top temperature, the horizontal plate 8 is rotated to above the nut 2. Before the thermocouple 4 is inserted into the nut 2, it is first passed through the circular hole 9, and the two symmetrical limit blocks 10 are used to clamp and limit the position, so that the thermocouple 4 does not need to be held manually for a long time when measuring the temperature, and it can also be well limited when the temperature measuring position of the thermocouple 4 is adjusted up and down.

[0021] The opposing surfaces of the two limit blocks 10 are arc surfaces, which match the arc surfaces of the thermocouple 4 and clamp more closely; a slide bar 11 is fixed on the opposite side of the two limit blocks 10, and the slide bar 11 slides through the cross plate 8. A spring 12 is sleeved on the slide bar 11, and one end of the spring 12 is fixed to the slide bar 11, and the other end of the spring 12 is fixed to the cross plate 8. The clamping of the two limit blocks 10 is achieved through the elastic force of the spring 12, which pushes the slide bar 11 to slide toward the center of the circular hole 9, so that the two limit blocks 10 are close to each other.

[0022] A pin 13 is inserted through the top of the vertical plate 7 supported by the horizontal plate 8. When the thermocouple 4 is used to measure the furnace top temperature, the horizontal plate 8 is rotated above the nut 2, and the pin 13 limits the horizontal plate 8 from tilting at the non-rotating position.

[0023] Working principle: There are two situations when the utility model is used. In the first situation, when the temperature detection is not performed, the bolt 3 is screwed into the nut 2, and the bottom of the bolt 3 is simultaneously extended into the through hole 5 to block the through hole 5;

[0024] The second method is to use a thermocouple 4 to measure the furnace top temperature. The bolt 3 is removed from the nut 2, and the cross plate 8 is rotated above the nut 2. The pin 13 limits the non-rotating portion of the cross plate 8 from tilting up. The thermocouple 4 is passed through the water seal cover 1 along the circular hole 9, the nut 2, and the through hole 5, and extended into the furnace top for temperature measurement. When the thermocouple 4 is inserted through the circular hole 9, two symmetrical limit blocks 10 are used to clamp and limit the position.

[0025] The utility model is safe and reliable, and is easy to operate. It only needs to insert the thermocouple 4 into the newly opened through hole 5 on the water sealing cover 1 to measure the temperature. It can be operated by one person, avoiding the tedious operation of two people lifting the water sealing cover 1 in the past. There is no need to replace the water sealing cover 1, there is no situation where the furnace mouth is wide open, and there is no need to worry about a large amount of air entering the carbonization chamber. It is safer and more convenient. The thermocouple 4 is limited by the bracket 6, so there is no need to hold it for a long time manually, and it can be well limited when the temperature measuring position of the thermocouple 4 is adjusted up and down.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
