Description

Technical Field

[0001] This utility model relates to the field of concrete preparation technology, specifically to a boiling tank. Background Technology

[0002] The boiling test utilizes the property that free calcium oxide slowly matures and forms ettringite during hydration. This process is very slow at room temperature, but it is accelerated at high temperatures. When free calcium oxide in concrete reacts with water to form ettringite, its volume is larger than that of the original material, which will generate internal stress in the hardened concrete, leading to microcracks or volume expansion. The boiling test accelerates this process to test the volume stability of concrete.

Cooling devices are provided on both sides of the cylinders. Each cooling device includes multiple second connecting rods fixedly mounted on the lower surface of the top plate, with fans connected to the bottom ends of the second connecting rods. The fans are located on both sides of the boiling chamber. This invention provides a concrete boiling chamber where the cylinders on both sides of the boiling chamber move the sample frame out of the chamber, reducing manual operation. Simultaneously, the fans on both sides of the boiling chamber move upwards with the sample frame, activating to cool the concrete inside the sample frame, accelerating the cooling time and improving work efficiency.

[0031] The working principle and usage process of this utility model are as follows: First, combined with... Figures 1-4 As shown, the lower end face of the box 1 has an opening 2, and both the opening 2 and the gear ring 3 are elliptical in shape. The central axis of the gear ring 3 and the opening 2 are the same straight line. The lower end face of the box 1 has a sliding groove 6, which is also elliptical in shape. A bracket 12 is slidably connected to the sliding groove 6. The bracket 12 is connected to the gear ring 3 through the meshing of the gear 11 and the sliding groove 6 to form a sliding structure. The front end of the concrete box 13 connected to the bracket 12 is fixed with a conductive groove 15. The rotating shaft 10 is rotatably connected to the lower end face of the bracket 12. The sum of the length of the rotating shaft 10 and the thickness of the gear 11 is equal to the distance between the lower end face of the bracket 12 and the gear ring 3. When the power switch of the motor 16 is turned on, the motor 16 drives the gear 11 to rotate through the rotating shaft 10. The gear 11 and the gear ring 3 are meshed, which facilitates the sliding of the bracket 12 on the sliding groove 6, thereby facilitating the transfer of the concrete box 13 inside the box 1.

[0032] Combination Figure 1 and Figure 4 As shown, the conductive groove 15 and the conductive block 9 are connected by a snap-fit ​​connection, and the conductive block 9 is electrically connected to the conductive groove 15 via a wire 8. The wire 8 has a spiral winding structure on the outer surface of the electric telescopic rod 7. The bracket 12 is fixedly connected to the support frame 17 at equal intervals inside, and the upper end of the bracket 12 is snap-fitted to the concrete box 13. Fixing bolts 18 are connected through the corners of the bracket 12. The motor 16 is installed on the lower end face of the support frame 17, and the support frame 17 and the bracket 12 are an integrated structure. The lower end face of the bracket 12 has a hollow structure. When the concrete box 13 conveys concrete to the conductive block... At point 9, the power switch of the electric telescopic rod 7 is turned on, and the electric telescopic rod 7 pushes the conductive block 9 to move backward. The conductive block 9 engages with the conductive groove 15, which facilitates electrical connection between the electric wire 8 and the heat-conducting block 14, making it convenient to heat the heat-conducting block 14, which is convenient for heating concrete and easy to use. The electric wire 8 is spirally wound on the outer surface of the electric telescopic rod 7 to increase the length of the electric wire 8 and avoid pulling and breaking, which would affect the use. After heating is completed, the electric telescopic rod continues to move the concrete box 13 to the protective cover 4, where the concrete is cooled, making it convenient to take out the concrete for experimental research. This is the working process of the boiling box.
