[0002] A rotary kiln refers to a rotating calcining kiln, which belongs to the category of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to the different materials they process. Cement kilns are mainly used to calcine cement clinker, and are divided into two categories: dry process cement kilns and wet process cement kilns. Metallurgical chemical kilns are mainly used in the metallurgical industry for magnetization roasting of lean iron ore in steel plants; oxidation roasting of chromium and nickel iron ores; roasting of high-alumina vanadium ore in refractory plants and roasting of clinker and aluminum hydroxide in aluminum plants; and roasting of chromium ore sand and chromium ore powder and other minerals in chemical plants.

[0003] When testing the temperature inside a rotary kiln, a temperature measuring shaft is usually buried in the wall of the rotary kiln, and the temperature inside the rotary kiln is measured by a wireless transmitter and receiver. However, this method may cause the temperature measuring shaft to be worn by materials, which may easily lead to damage to the temperature measuring shaft. At the same time, the position of the temperature measuring shaft is fixed, and only the temperature at a fixed position can be measured. The obtained temperature data is accidental and lacks accuracy. Utility Model Content

[0007] In one example, the temperature measuring component includes a temperature sensing probe, which is fixedly connected to the support plate. One side of the temperature sensing probe is fixedly connected to a temperature-resistant wire, which passes through the cross plate and the shell. The other end of the temperature-resistant wire is fixedly connected to a thermocouple display, and the thermocouple display is fixedly connected to the shell.

[0012] First, by setting the support plate, the temperature measuring component is inside the shell, which will not block the materials entering the rotary kiln body, and prevent the materials from colliding with the temperature measuring component and causing damage.

By controlling the depth of the support plate extending into the rotary kiln body, the temperature at different positions in the rotary kiln body is measured, and at the same time, the round rod is controlled to rotate left and right to increase the activity area of ​​the temperature measuring component, thereby increasing the temperature measurement area and increasing the measurement accuracy;

[0013] Secondly, by setting the bottom plate, when the temperature does not need to be measured, the bottom plate blocks the first circular through hole. Due to the size of the material, the bottom plate blocks the internal temperature and reduces the heat loss inside the rotary kiln body.

DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0022] like Figure 1 to Figure 4 As shown, the embodiment of the utility model proposes a rotary kiln temperature measuring device, including a rotary kiln body 1, a fixed ring 2 fixedly connected to the outer side of the rotary kiln body 1, a first circular through hole is arranged on the outer side of the rotary kiln body 1, a second circular through hole is arranged on the outer side of the fixed ring 2, and the radius is larger than the first circular through hole, the outer side of the fixed ring 2 is fixedly connected to a shell 3, a transverse plate 4 is slidably arranged in the shell 3, the lower surface of the transverse plate 4 is fixedly connected to a fixed plate 5, the lower surface of the fixed plate 5 is fixedly connected to a bottom plate 6, the bottom plate 6 cooperates with the first circular through hole, one side of the bottom plate 6 is rotatably connected to a round rod 7, one end of the round rod 7 is fixedly connected to a support plate 8, one side of the support plate 8 is provided with a temperature measuring component 9, the temperature measuring component 9 is inside the shell 3, when the rotary kiln body 1 is moved to the bottom plate 6, the temperature measuring component 9 is rotated to the bottom plate 6, and the temperature measuring component 9 is located inside the shell 3. When adding materials, the temperature measuring component 9 is in the shell 3, which will not block the materials entering the rotary kiln body 1, and prevent the materials from colliding with the temperature measuring component 9 and causing damage. The bottom plate 6 is located in the first circular through hole to block the first circular through hole. When temperature measurement is required, the cross plate 4 slides down to push the bottom plate 6 into the rotary kiln body 1, and the support plate 8 and the temperature measuring component 9 on one side enter the rotary kiln body 1 together to measure the temperature in the rotary kiln body 1. The temperature at different positions in the rotary kiln body 1 is measured by controlling the depth of the support plate 8 extending into the rotary kiln body 1, and the round rod 7 is controlled to rotate left and right to increase the activity area of ​​the temperature measuring component 9, thereby increasing the temperature measurement area and increasing the measurement accuracy.

[0023] like Figure 2As shown, the bottom plate 6 is the same size as the first circular through hole, the same thickness as the rotary kiln body 1, the same material as the rotary kiln body 1, the centers of the first circular through hole and the second circular through hole are on the same axis, the cross plate 4 cooperates with the second circular through hole, and when the temperature does not need to be measured, the bottom plate 6 blocks the first circular through hole. Due to the size of the material, the bottom plate 6 blocks the internal temperature and reduces the heat loss inside the rotary kiln body 1. When measuring the temperature, after the bottom plate 6, the support plate 8 and the temperature measuring component 9 enter the rotary kiln body 1, the cross plate 4 enters the second circular through hole and blocks the first circular through hole, reducing the heat loss during measurement.

[0024] like Figure 3 As shown, the temperature measuring component 9 includes a temperature sensing probe 91, which is fixedly connected to the support plate 8. A heat-resistant wire 92 is fixedly connected to one side of the temperature sensing probe 91. The heat-resistant wire 92 passes through the cross plate 4 and the shell 3. The other end of the heat-resistant wire 92 is fixedly connected to a thermocouple display 93. The thermocouple display 93 is fixedly connected to the shell 3. During measurement, the support plate 8 drives the temperature sensing probe 91 into the rotary kiln body 1 for temperature measurement. The thermocouple display 93 that displays the internal temperature is fixed on the shell 3. The temperature data is transmitted to the thermocouple display 93 through the heat-resistant wire 92 for display. The heat-resistant wire 92 is flexible and curved, so the staff can directly observe it, which is more convenient.

[0025] like Figure 3 As shown, the outer side of the rotary kiln body 1 is fixedly connected to a vertical rod 10, the vertical rod 10 passes through the second circular through hole, the vertical rod 10 passes through the horizontal plate 4 and is slidably connected to the horizontal plate 4, the inner wall of the shell 3 is fixedly connected to the mounting plate 11, the upper surface of the mounting plate 11 is fixedly connected to the servo motor 12, the main shaft of the servo motor 12 is fixedly connected to a threaded rod 13, the threaded rod 13 passes through the horizontal plate 4 and is threadedly connected to the horizontal plate 4. When measuring temperature, the servo motor 12 is turned on to drive the threaded rod 13 to rotate, and the threaded rod 13 controls the horizontal plate 4 to slide downward. The horizontal plate 4 drives the bottom plate 6 through the fixed plate 5 to enter the rotary kiln body 1 for temperature measurement. The servo motor 12 controls the horizontal plate 4 to slide to measure temperature, which is more convenient and quicker and reduces manual participation.

[0026] like Figure 4As shown, one side of the round rod 7 is fixedly connected to the gear 14, and the sliding rod 15 is slidably connected to the cross plate 4. One side of the sliding rod 15 is provided with teeth, which mesh with the gear 14. The sliding rod 15 passes through the shell 3 and is slidably connected to the shell 3. One side of the sliding rod 15 is fixedly connected to the square plate 16, and a spring 17 is fixedly connected between the square plate 16 and the cross plate 4. The upper end of the sliding rod 15 is fixedly connected to the handle 18. When the temperature sensing probe 91 and the support plate 8 enter the rotary kiln body 1, the sliding rod 15 can be pushed at this time to slide the sliding rod 15 up and down. The sliding rod 15 drives the gear 14 to rotate left and right, thereby causing the support plate 8 and the temperature sensing probe 91 to rotate left and right. The rotating area is fan-shaped, which increases the temperature measurement area of ​​the temperature sensing probe 91, and multi-position temperature sampling is performed to improve accuracy.

[0027] Working principle: when it is not necessary to measure the temperature, the bottom plate 6 blocks the first circular through hole. When measuring the temperature, the servo motor 12 is turned on to drive the threaded rod 13 to rotate. The threaded rod 13 controls the horizontal plate 4 to slide downward. The horizontal plate 4 drives the bottom plate 6 and the temperature probe 91 to enter the rotary kiln body 1 through the fixed plate 5 for temperature measurement. At this time, the sliding rod 15 can be pushed to slide up and down. The sliding rod 15 drives the gear 14 to rotate left and right, thereby causing the support plate 8 and the temperature probe 91 to rotate left and right. The rotation area is fan-shaped, which increases the temperature measurement area of ​​the temperature probe 91.
