[0005] To achieve the above objectives, a device for determining the carbonate decomposition rate of raw materials entering the kiln is provided, comprising a support frame one, a support frame two, and a water tank.

[0028] Working principle: Before the measurement, the sampling personnel collect undecomposed raw material samples at the belt scale before the raw material enters the elevator. Ten minutes after collecting the undecomposed raw material, a pre-decomposed raw material sample is collected before the feed pipe of the final preheater enters the kiln tail smoke chamber. After sampling, let it cool slightly for five minutes, and then immediately put the sample into a sealed bottle. After the sampling is completed, if it is necessary to adjust the height of the burette 11 or the gas measuring tube 26, disconnect the connection between the fixing bolts and fixing nuts on both sides of the bracket 1 or bracket 24, adjust the height of the clamping sleeve 8, and then... The height adjustment holes 2 on both sides of bracket 1 or bracket 2 correspond to the positioning holes 7 on the clamping rod 5. The fixing bolts are reinserted and connected to the fixing nuts to complete the height adjustment of the clamping sleeve 8. The burette 11 and the gas measuring tube 26 are placed into the two clamping sleeves 8 respectively. At the same time, the fixing bolts are inserted into the fixing holes 10. The other end of the fixing bolts is connected to the nuts and the nuts are tightened to complete the installation of the burette 11 and the gas measuring tube 26. Thus, the installation height of the burette 11 or the gas measuring tube 26 can be adjusted.

[0029] During the measurement, open the three-way gas valve 23 to allow ventilation to the atmosphere. Raise the balance bottle 27 and raise the solution in the gas measuring tube 26 to the zero mark. Align the instrument with zero point, immediately close the three-way gas valve 23, lower the balance bottle 27, and observe the liquid level change for thirty seconds. If the liquid level does not drop, the seal is qualified. Accurately weigh 0.1 gram of undecomposed raw material sample and place it in the reaction bottle 14 containing two milliliters of distilled water. Immediately shake to disperse the sample and check the seal. If qualified, add five milliliters of hydrochloric acid to the reaction bottle 14 and gently shake until the liquid level no longer drops. Place it in the water trough 13 and start recording the time. After five minutes of reaction, pick up the reaction bottle 14 and gently shake it while observing the liquid level in the gas measuring tube 26 until it stabilizes. Until the reaction bottle 14 stops falling, place it in the middle of the two positioning plates 18 in the water tank 13. Turn the knob 21 to rotate the screw 20. One end of the screw 20 pushes the positioning plate 18 to clamp and position the reaction bottle 14. Lift the balance bottle 27 and move it up and down along the gas measuring tube 26 until the liquid level in the balance bottle 27 is at the same height as the liquid level in the gas measuring tube 26. Read the volume indicated by the gas measuring tube 26. Calculate the carbon dioxide gas content produced after the undecomposed raw material reacts with hydrochloric acid using the formula. Accurately weigh 0.5 grams of pre-decomposed raw material sample and repeat the above operation to determine the carbon dioxide gas content produced after the pre-decomposed raw material reacts with hydrochloric acid. The decomposition rate of the raw material entering the kiln can then be calculated.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
