Description

Technical Field

[0001] This utility model relates to a blast furnace molten iron temperature measuring device, belonging to the technical field of blast furnace ironmaking equipment. Background Technology

[0002] Currently, the contact molten iron temperature measuring gun used in blast furnaces requires manual insertion of the measuring rod to measure the temperature, which is inefficient. Furthermore, due to different operating habits, the insertion depth into the molten iron can vary, leading to deviations in the measured temperature and resulting in inaccurate readings. Non-contact molten iron temperature measuring devices are easily affected by factors such as smoke and dust, resulting in insufficient accuracy and reliability. Summary of the Invention

[0003] The purpose of this invention is to provide a blast furnace molten iron temperature measuring device. By arranging temperature measuring guns in a circumferential array, the device height is fixed, and the depth to which the temperature measuring rod is inserted into the molten iron surface is fixed, resulting in higher temperature measurement accuracy. It can realize online continuous measurement of molten iron temperature, improve temperature measurement accuracy, reduce labor intensity, and automatically remove the temperature measuring rod after the temperature measurement is completed, thus solving the above-mentioned problems existing in the background technology.

The temperature measuring rod is installed on the top of the temperature measuring gun, and the temperature measuring gun is installed on a circular ring. The circular ring is driven by a motor to achieve circumferential rotation. The temperature measuring gun is connected to the digital display component through a power cord. The temperature measuring rod removal device is a steel plate with a gap in the middle, which is placed at an angle above the molten iron trough. The size of the gap matches the temperature measuring gun and is smaller than the diameter of the temperature measuring rod.

[0005] It also includes a bracket, which is a triangular structure with its two ends of the base fixed to the refractory material of the main trough on both sides of the molten iron trough, and the middle part of the temperature measuring gun fixed to the top of the bracket.

[0006] There are four temperature guns, arranged in a cross shape on the ring.

[0007] The frequency of the ring's rotation is matched with the temperature measurement time interval.

[0010] To make the purpose, technical solution, and advantages of this utility model clearer, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described implementation cases are only a small part of this utility model, not all of them. All other implementation cases obtained by those skilled in the art based on the implementation cases of this utility model without creative effort are within the protection scope of this utility model.

[0011] A blast furnace molten iron temperature measuring device includes a temperature measuring component, a digital display component 4, and a temperature measuring rod removal device 5. The temperature measuring component includes a temperature measuring rod 1 and a temperature measuring gun 2. The temperature measuring rod 1 is installed on the top of the temperature measuring gun 2, and the temperature measuring gun 2 is installed on a ring. The ring is driven by a motor to achieve circumferential rotation. The temperature measuring gun 2 is connected to the digital display component 4 through a power cable 3. The temperature measuring rod removal device 5 is a steel plate with a gap 10 in the middle, which is placed at an angle above the molten iron trough 7. The size of the gap 10 matches the temperature measuring gun 2 and is smaller than the diameter of the temperature measuring rod 1.

[0012] It also includes a bracket 6, which is a triangular structure with its two bottom ends fixed to the main trough refractory material 8 on both sides of the iron trough 7, and the middle part of the temperature measuring gun 2 fixed to the top of the bracket 6.

[0013] The temperature measuring gun 2 has four guns, which are arranged in a cross shape on the ring.

[0014] The frequency of the ring's rotation is matched with the temperature measurement time interval.

[0015] In practical applications, this utility model is installed on the upper part of the molten iron trough 7 where temperature measurement is required. The temperature measuring component rotates at a certain circumferential speed, which can be set according to the temperature measurement interval. When the temperature measuring gun 2, on which the temperature measuring rod 1 is installed, rotates to contact the molten iron surface 9 in the molten iron trough 7, the temperature measurement process begins. The temperature measurement data is transmitted to the digital display component 4 through the power line 3, completing one temperature measurement. Under the rotation drive, the temperature measuring rod 1 detaches from the molten iron surface 9, completing the temperature measurement process. When the temperature measuring gun 2 enters the temperature measuring rod removal device 5, the temperature measuring gun 2 passes through the gap. Since the temperature measuring rod 1 cannot pass through the gap, it is detached from the temperature measuring gun 2 under the force of the device and is retrieved. This process is repeated to achieve continuous periodic temperature measurement. Since the height of the device is fixed, the depth to which the temperature measuring rod 1 is inserted into the molten iron surface is fixed, resulting in higher temperature measurement accuracy.

[0016] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
