| titleOfInvention | Cement boiling box |
| abstract | The utility model relates to the technical field of cement performance testing, and discloses a cement boiling box which comprises a protective box body, wherein a boiling chamber and an electric room are respectively arranged on the front surface of the protective box body. According to the utility model, the test piece rack is placed on the upper surface of the support plate, water in the boiling box is heated through the heating pipe, so that the water is boiled in about minutes, after the water is boiled, bubbles are generated on the surface of the heating pipe and continuously rise, when the bubbles touch the filter plate, the bubbles are split into small bubbles which can penetrate through the filter plate, and under the action of the support plate, the small bubbles move to the periphery of the filter plate along the bottom of the filter plate, so that the small bubbles rise along the inner wall of the boiling box and are prevented from contacting with a cement test piece, and therefore, the impact on the test piece caused by the contact between the cement test piece and the bubbles when the bubbles rise due to water boiling is avoided, and further, the cement test piece is prevented from being impacted, so that residues fall off, even the test piece is damaged, and the measurement result is influenced. |
