The molten iron double-circular sampling and temperature measurement composite probe includes a paper tube with coated sand at one end. Two sampling chambers are provided in the coated sand, namely the first circular sampling chamber and the second circular sampling chamber. The two sampling chambers have the same structure and are arranged in parallel and symmetrically. There is a certain distance between them and they are connected by a connecting channel.

Compared with the traditional stamping part sampling, the round sample has no pores and no slag, is round and full, and has a smooth surface. The surface is flat and smooth, the surface is easy to cut, the spectrum marking is well matched, and the data is accurate with small deviation; the temperature measuring head is embedded in the coated sand, the head is not easily damaged, the platinum-rhodium wire will not be broken, the temperature measurement success rate is high, the deviation is small, and the stability is good.

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The following is combined with Figure 1-4 To further explain this application,

[0023] The present application discloses a composite probe for measuring temperature of molten iron using double-circle sampling. Figure 1-Figure 3 A composite probe for sampling and measuring temperature of molten iron double-circle samples, comprising a composite probe body 1, a slag breaking cap 2 provided on the surface of the composite probe body 1, and a disassembly mechanism 3 provided on the surface of the composite probe body 1;

[0024] The disassembly mechanism 3 includes a rotating block 301, which is fixedly mounted on the surface of the slag breaking cap 2. The inner wall of the rotating block 301 is rotatably connected to a connecting rod 302. A docking block 303 is fixedly mounted on the surface of the composite probe body 1. The inner wall of the docking block 303 cooperates with the surface of the connecting rod 302. The surface of the docking block 303 is threadedly connected to a positioning block 304. The bottom of the positioning block 304 is in close contact with the top of the docking block 303.

[0025] Reference Figure 3 A slot 4 is provided on the top of the docking block 303. The inner cavity of the slot 4 cooperates with the surface of the positioning block 304. By providing the slot 4, when the positioning block 304 enters the slot 4, it squeezes the connecting block 5 and fixes the position of the positioning block 304, thereby ensuring the stability of the positioning block 304 during operation.

[0026] Reference Figure 2 and Figure 3 The top of the rotating block 301 is fixedly mounted with a connecting block 5, and the bottom of the docking block 303 is provided with a connecting groove 6. The surface of the connecting block 5 is slidably connected with the inner cavity of the connecting groove 6. Through the sliding connection between the connecting block 5 and the connecting groove 6, when the bottom of the docking block 303 contacts the top of the rotating block 301, the connecting block 5 can enter the inner cavity of the connecting groove 6, thereby achieving accurate stacking of the docking blocks 303 and 303.

[0027] Reference Figure 4 , a baffle 7 is fixedly installed on the inner wall of the slag breaking cap 2, and a spring 8 is provided on the surface of the baffle 7. One end of the spring 8 is fixedly connected to the surface of the baffle 7, and the other end of the spring 8 is fixedly connected to the inner wall of the baffle 7. By providing the baffle 7, the spring 8 can be supported. When the slag breaking cap 2 is deformed, the spring 8 will be squeezed to compress the spring 8. Under the reaction generated by the compression of the spring 8, the force on the slag breaking cap 2 can be buffered to prevent the slag breaking cap 2 from squeezing the temperature measuring head;

[0028] Reference Figure 4 A telescopic rod 9 is fixedly installed at the bottom of the baffle 7. The telescopic end of the telescopic rod 9 is fixedly connected to the inner wall of the slag breaking cap 2. The inner cavity of the spring 8 is sleeved on the surface of the telescopic rod 9. By setting the telescopic rod 9, the deformation of the spring 8 can be guided to avoid excessive lateral deformation of the spring 8 and increase the service life of the spring 8.

[0029] Reference Figure 2 An elastic sheet 10 is fixedly installed on the top of the baffle 7. The elastic sheet 10 is made of a high-elastic alloy. By providing the elastic sheet 10, when the slag breaking cap 2 is subjected to excessive force, the force generated by the deformation spring 8 is difficult to buffer, and the elastic sheet 10 will come into contact with the temperature measuring head. The elastic force of the elastic sheet 10 realizes contact buffering of the temperature measuring head, thereby further protecting the temperature measuring head.

[0030] Reference Figure 2 A stopper 11 is fixedly mounted on the surface of the connecting rod 302. The bottom of the stopper 11 cooperates with the top of the positioning block 304. By setting the stopper 11, the upward movement distance of the positioning block 304 can be limited, thereby preventing the positioning block 304 from separating from the connecting rod 302.

[0031] Working principle: The composite probe body 1 includes a paper tube, one end of which is provided with coated sand, and two sampling chambers are provided in the coated sand, namely the first circular sampling chamber and the second circular sampling chamber. The two sampling chambers have the same structure and are arranged in parallel and symmetrically. There is a certain distance between them and they are connected by a connecting channel. In addition, a temperature measuring head is provided in the coated sand to measure the temperature of the molten iron. The temperature measuring head is provided at one end of the composite probe body 1 to detect the temperature of the molten iron. The temperature measuring head is protected by the slag breaking cap 2. When the slag breaking cap 2 is installed, the rotating The top of the movable block 301 contacts the bottom of the docking block 303, and the connecting rod 302 is rotated to enter the inner cavity reserved for the docking block 303, and the positioning block 304 is rotated. The upper half of the connecting rod 302 is provided with a thread, which can be threadedly connected to the positioning block 304, and the positioning block 304 can be squeezed on the docking block 303, thereby fixing the position of the slag breaking cap 2. At the same time, it can be convenient for the user to replace the deformed or damaged slag breaking cap 2, reducing the difficulty of replacing the slag breaking cap 2, and making it convenient for the user to detect and repair the temperature measuring head.
