Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a cement clinker calcining temperature detection device. Background Art

[0002] Cement clinker refers to the raw material of cement after the calcination process, and is one of the key raw materials for cement production. Cement clinker is usually made by calcining limestone (calcium stone), clay and other auxiliary raw materials (such as iron ore, silicate, etc.). In the cement production process, cement clinker is ground and mixed with an appropriate amount of gypsum (or other mineral admixtures) to make cement. The calcination of cement clinker refers to the process of heating the raw material of cement at high temperature. Its purpose is to make the raw material undergo chemical reaction and physical change through calcination, so as to form clinker suitable for making cement. The detection of the calcination temperature of cement clinker is a very critical link in the cement production process, which directly affects the quality of clinker and the performance of the final cement product. In the prior art, the positioning of the thermometer is not accurate enough when installing it. Inaccurate positioning will cause the position of the thermometer to shift or move, affecting the temperature measurement accuracy and stability, and requiring frequent calibration. In addition, the prior art mostly uses contact temperature measurement equipment. When temperature measurement is not required, the temperature measurement equipment will also be in contact with the raw material for a long time, resulting in long-term wear of the temperature measurement equipment and reducing its service life.

[0007] Furthermore, a motor is installed on the support frame, a reducer is installed on the output end of the motor, and the motor is transmission-connected to the blocking cover via the reducer.

[0008] The beneficial effects of adopting the above further scheme are:

[0009] The reducer can convert the high speed and low torque of the motor into low speed and high torque, providing sufficient power to drive the cover. The motor can more accurately control the opening and closing position of the cover to ensure accurate exposure and covering of the temperature measurement window, and ensure the normal operation of the cover even when working for a long time or in poor environmental conditions.

[0010] Furthermore, there are two blocking covers in total, and the two blocking covers are symmetrically distributed on both sides of the temperature measuring window, and the two blocking covers are connected and fixed by a connecting shaft.

When closed, they can completely cover the temperature measuring window to prevent dust, debris or other environmental factors from entering, protect the infrared thermometer, and improve the temperature measurement accuracy and equipment life.

[0013] Furthermore, the material discharge guide pipe is arranged at the connection of the two conveying devices through a groove cover, so that the clinker transported from the upstream is guided to be discharged through the material discharge guide pipe, and the clinker temperature is measured by an infrared thermometer on the material discharge guide pipe.

[0016] Furthermore, the support frame is provided with three supporting legs in total, and the support frame is mounted on the material discharge guide tube through the supporting legs.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The three legs can effectively slow down and disperse vibration, reduce the impact of external vibration on the unloading guide tube and infrared thermometer, and improve temperature measurement accuracy. By reducing vibration transmission, the infrared thermometer and other sensitive equipment are protected and their service life is extended.

[0019] Furthermore, a positioning groove is formed through the support frame, and the infrared thermometer is installed on the support frame through the positioning groove.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] The positioning groove ensures that the infrared thermometer can be accurately aligned with a specific position during installation to avoid installation errors. The infrared thermometer can be easily fine-tuned in the groove to obtain the best temperature measurement position, which simplifies the installation and adjustment process and improves the accuracy and reliability of temperature measurement. The positioning groove provides a fixed position, making the infrared thermometer more stable after installation and not easy to move or deviate, thereby improving the stability of the thermometer.

[0022] The beneficial effects of the utility model are:

[0023] The infrared thermometer can measure the temperature of high-temperature clinker in a non-contact manner, with fast response speed and high measurement accuracy. The infrared thermometer can read temperature data instantly, greatly improving the efficiency and accuracy of temperature detection. The device can also monitor the temperature in real time during the clinker transportation process without affecting the normal transportation of clinker, thus realizing continuous monitoring during the production process. This helps to timely discover and solve temperature abnormalities in production, ensuring product quality and production safety.

[0024] Equipped with a motor and a reducer, the motor drives the cover to rotate, automatically exposing or covering the temperature measuring window as needed, and can automatically control the opening and closing of the temperature measuring window. This design reduces manual intervention, reduces the frequency and intensity of manual work, is simple to operate, and is convenient for integration into automated production lines.
