Description

Technical Field

[0001] The present application relates to the technical field of cement testing, and in particular to a cement testing curing box. Background Art

[0002] In the cement industry, cement test curing box is an important equipment used to simulate the environmental conditions of cement during the hardening process, so as to evaluate the performance of cement. Cement test curing box is also called cement curing box, which is specially used for standard curing of cement test blocks. It is suitable for various cement product factories, construction units, highway and bridge projects, and relevant scientific research and quality inspection departments to perform standard curing and testing on the strength and setting time of cement, concrete and cement product samples. At present, most of the cement test curing boxes on the market are constant temperature and humidity type, which simulate the environment of cement hardening by controlling the temperature and humidity in the box. However, during the testing process, cement is mostly placed statically in the box, but because cement contains some water in addition to mud and sand, static placement can easily lead to solid-liquid separation, making the cement distribution uneven, affecting the simulation effect of cement hardening.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a cement test curing box. Figure 1-Figure 2, including a curing box 1, the outside of the curing box 1 is hinged with a sealed door 7, a bracket 2 is fixed on the top of the curing box 1, a temperature controller 3 is installed on the bracket 2, and the temperature and humidity of the internal cement test can be observed through the temperature controller 3, a feeding pipe 5 is provided on the outer wall of one side of the curing box 1, cement can be added at any time for testing through the feeding pipe 5, and a curing liner 8 is rotatably installed inside the curing box 1, an engine 4 is installed on the outer wall of one side of the curing box 1, the output end of the engine 4 passes through the inner wall of the curing box 1 and is transmitted to one side of the curing liner 8, and then the curing liner 8 can be driven to rotate in the curing box 1, a test groove 10 is opened inside the curing liner 8, a discharge pipe 9 is fixed on one side of the bottom of the curing liner 8, and a regulating valve is installed on the discharge pipe 9, and the mixed cement inside can be discharged by opening the regulating valve.

[0020] A reinforcing frame 13 is fixed to the inner wall of the curing box 1 on one side close to the feeding pipe 5, and a conduit 6 is fixed to the bottom of the feeding pipe 5 in an integrated structure. The conduit 6 extends into the reinforcing frame 13 at one end away from the feeding pipe 5, and an injection port 17 is opened inside one side of the curing liner 8, and the reinforcing frame 13 extends to the inside of the injection port 17. Therefore, cement can be transported to the inside of the test tank 10 through the conduit 6, and the test tank 10 is arranged to be inclined toward one end of the discharge pipe 9, so as to facilitate the mixed cement inside to be diverted to one side.

[0021] like Figure 3 As shown, a connecting shaft 14 is fixed at the center of the inner wall of the reinforcing frame 13, and a plurality of filter discs 11 are fixedly arranged at equal intervals inside the curing inner tank 8. As the inner diameter of the curing inner tank 8 decreases from one end to the other end, the filter discs 11 also gradually decrease. A cleaning frame 15 is provided on one side surface of the filter disc 11, and the cleaning frame 15 is fixedly connected to the outer wall of the connecting shaft 14;

[0022] When the maintenance liner 8 rotates, the cleaning frame 15 will contact the surface of the filter disc 11. Since a brush strip 16 is fixedly provided at one end of the cleaning frame 15 close to the filter disc 11, the cement on the surface can be cleaned by the brush strip 16. The surface of the filter disc 11 is provided with a plurality of filter holes 12 equidistantly arranged along the circumferential direction to allow cement to be filtered.

[0023] The implementation principle of a cement test curing box in an embodiment of the present application is as follows: when in use, the cement to be tested is injected through the feeding pipe 5, and the cement is transported through the conduit 6 and discharged into the interior of the curing liner 8 through the injection port 17, and then the engine 4 is driven to drive the curing liner 8 to rotate in the curing box 1, which can drive the internal cement ingredients to tumble, and filter and transport them from one side to the other through the filter holes 12 inside the filter disc 11 in turn, and during the tumbling process, the brush strips 16 on the surface of the cleaning frame 15 will contact the filter disc 11, which can not only clean the cement but also promote cement filtration to avoid blockage. When the cement is mixed, the regulating valve outside the discharge pipe 9 is opened, and the cement is discharged downward. A container can be placed in the curing box 1 in advance for holding cement, and then the temperature and humidity in the box are controlled by adjusting the temperature controller 2 to simulate the cement hardening environment, which is convenient for cement testing.
