Description

Technical Field

[0001] The invention relates to a low-pressure stirring and molding integrated device, belonging to the field of concrete testing equipment. Background Art

[0002] As a building material with a wide source and easy to manufacture, concrete is widely used in various construction scenarios. However, in a low-pressure environment, the performance of concrete will be affected, which makes the concrete construction in some plateau areas very different from that in ordinary areas. It is necessary to study the mechanical properties of concrete in high-altitude and cold areas.

[0003] However, there are defects in the current experimental conditions for studying low-pressure concrete. On the one hand, most of the equipment simulating low-pressure environments is prepared or cured in a low-pressure environment, and then transferred to a normal-pressure environment to test the performance of fresh mixes. During the test, the air pressure changes greatly, which cannot fully reflect the true situation of the impact of the low-pressure environment on concrete bubbles. On the other hand, field tests in the plateau and plains may result in different raw material properties and different temperatures of the mixture out of the machine, which will also affect the test results. In a closed low-pressure environment, the concrete is added, mixed, molded, and cured to the age. The whole process is cumbersome and difficult to operate. When adding and moving the molded concrete specimens, pressure changes are prone to occur, which affects the experimental results. For this reason, a low-pressure mixing and molding integrated device is provided to solve the above problems. Summary of the invention

The hose 5352 is fixedly installed at the end of the solenoid valve 5351; the unloading nozzle 5353 is fixedly installed at the bottom end of the hose 5352; the sliding push frame 5354 is slidably set at the bottom of the cantilever support arm 54, and the bottom end of the sliding push frame 5354 is movably hinged to the unloading nozzle 5353; the linear motor 5355 is fixedly set at the bottom of the cantilever support arm 54, and the output end of the linear motor 5355 is fixedly connected to the sliding push frame 5354.

[0069] A linear support rod 58 parallel to each other is arranged below the cantilever support arm 54, and the two ends of the linear support rod 58 are fixedly connected to the rotating frame 52 and the vibration motor 59 respectively. A heating support platform 51 is fixedly arranged in the middle of the annular frame 61, and the rotating frame 52 is rotatably connected to the middle of the heating support platform 51. A rotating motor 57 is fixedly arranged on one side of the top of the heating support platform 51. The interior of the heating support platform 51 is rotatably connected with a driving gear 510 and a passive gear 511 that mesh with each other. The output end of the rotating motor 57 is fixedly connected to the driving gear 510, and the passive gear 511 is fixedly sleeved on the outer surface of the heating support platform 51. A sewage trough 64 is fixedly arranged on one side of the top of the annular frame 61, and a sewage pipe 7 is installed on one side of the bottom end of the sewage trough 64. The linear support rod 58 and the vibration motor 59 are rotatably connected inside the annular frame 61.

[0070] Working principle: When the device is used, firstly, the raw materials such as cement, sand, gravel and water are stored in different weighing metering machines 43, and then the sealing cover 44 on the top is closed. Then, by starting the vacuum pump 23, the negative pressure inside the entire low-pressure sealed cabin 1 is adjusted, and the connecting hole 42 is used to make the external sealed container 41 and the low-pressure sealed cabin 1 have the same pressure, so as to create a constant low-pressure environment for the entire experiment.

[0071] Then, by starting the rotating motor 57, the driving gear 510 and the driven gear 511 are meshed, thereby driving the rotating frame 52 to rotate, so that the mixing barrel 531 moves to the corresponding lower part of the inclined material guide pipe 45. At this time, the weighing metering machine 43 is used to quantitatively discharge the materials, so that the materials fall into the mixing barrel 531 through the inclined material guide pipe 45, and the sand, cement, gravel and water are added in sequence. Then, the stirring motor 534 is started, so that the stirring roller 533 stirs and mixes the materials in a low-pressure environment.

[0072] When the material is stirred, the rotary motor 57 is started again to drive the stirring barrel 531 to move to the top of a group of test mold boxes 62. At this time, the linear motor 5355 is started to push the sliding push frame 5354 to slide outward, and the sliding push frame 5354 drives the discharge nozzle 5353 to move to an outward state. At this time, the solenoid valve 5351 is started to make the material inside the stirring barrel 531 flow downward and fall into the test mold box 62. Then the solenoid valve 5351 is closed, and the linear motor 5355 contracts to drive the discharge nozzle 5353 to move to an inward state. At this time, part of the residual material drips into the annular residual material recovery groove 63. Before use, a waterproof film is pre-pasted in the annular residual material recovery groove 63 so that the residual material falls on the waterproof film. After the test is completed, the waterproof film and the solidified residual material are uniformly recovered;

[0073] In the above process, as the mixing barrel 531 moves to the top of the trial mold box 62, the vibration motor 59 moves synchronously to the bottom of the trial mold box 62. At this time, the vibration motor 59 is started to vibrate the trial mold box 62. After the vibration is completed, the concrete inside the trial mold box 62 can enter the curing stage in situ.

[0074] During the maintenance stage, the vacuum pump 23 is used to maintain a constant pressure in the internal cavity, and the temperature and humidity sensor 25 is used to monitor the internal temperature and humidity. The humidifier nozzle 8 is then used to adjust and maintain the humidity, and the heating support table 51 is used to control and adjust the temperature.

[0075] Then the rotating motor 57 is started, so that the mixing barrel 531 moves to the top of the next group of trial mold boxes 62 to pour the materials. When the materials are poured, the rotating motor 57 drives the mixing barrel 531 to move to the bottom of the weighing metering machine 43 filled with water. At this time, water is poured into the mixing barrel 531, and then the stirring roller 533 stirs to clean the residual materials inside. Then the rotating motor 57 drives the mixing barrel 531 to move to the top of the sewage tank 64, opens the solenoid valve 5351, and discharges the clean water into the sewage tank 64 through the discharge nozzle 5353. The sewage in the sewage tank 64 is finally discharged to the outside through the sewage pipe 7, and then the next group of concrete mixing operations is carried out;

[0076] The entire process is completed in the low-pressure sealed cabin 1 to ensure that the pressure environment inside the low-pressure sealed cabin 1 is constant. At the same time, the entire process of adding materials, mixing, molding and curing can be completed in the low-pressure sealed cabin 1. The visual probe 26 is used for full monitoring. At the same time, the temperature and humidity sensor 25 and the pressure gauge 24 are used to monitor the internal temperature, humidity and pressure in real time to ensure that the experimental environment can truly simulate the concrete molding in a low-pressure environment.
