Description

Technical Field

[0001] This invention relates to an integrated low-pressure mixing and molding device, belonging to the field of concrete testing equipment. Background Technology

[0002] Concrete, as a widely available and easy-to-manufacture building material, is widely used in various construction scenarios. However, under low-pressure environments, the performance of concrete is affected, which makes the construction of concrete in some plateau areas quite different from that in ordinary areas. It is necessary to study the mechanical properties of concrete in high-altitude and cold regions.

[0003] Current experimental conditions for studying low-pressure concrete have shortcomings. On the one hand, most equipment simulating low-pressure environments involves preparing or curing the concrete in a low-pressure environment and then transferring it to a normal-pressure environment to test the performance of fresh concrete. During the test, the pressure fluctuates significantly, failing to fully reflect the true impact of low-pressure environments on the air bubbles in the concrete. On the other hand, field tests in high-altitude and plain areas may encounter differences in the properties of raw materials and the temperature of the mixture exiting the mixer, which can also affect the test results. Furthermore, the entire process of adding, mixing, molding, and curing concrete to its designated age in a closed low-pressure environment is cumbersome and difficult to operate. Moreover, pressure changes can easily occur during the addition of materials and the movement of the molded concrete specimens, affecting the experimental results. Therefore, a low-pressure mixing and molding integrated device is provided to solve the above problems. Summary of the Invention

[0039] The beneficial effects of this invention are:

[0040] 1. This low-pressure mixing and molding integrated device connects an external sealed container to a low-pressure sealed chamber. During use, a constant low-pressure environment is created by a vacuum pump. The feeding, mixing, and subsequent molding and curing of concrete are then completed within the low-pressure sealed chamber. The entire process is monitored using a visual probe, and temperature and humidity sensors and pressure gauges are used to monitor the internal temperature, humidity, and pressure in real time, ensuring that the experimental environment can realistically simulate concrete molding under low-pressure conditions.

[0041] 2. This low-pressure mixing and molding integrated device uses a rotary motor to move the mixing drum to the bottom of the corresponding inclined guide pipe, where sand, cement, gravel, and water are added sequentially and then mixed. After mixing, the rotary motor moves the mixing drum to the top of a set of test mold boxes and pours the material into the test mold boxes through the discharge nozzle. Then, the vibration motor follows the mixing drum to the bottom of the test mold box for vibration. The mixing drum is then cleaned by adding water, and the cleaning water is poured into the sewage tank. This makes the process of adding, discharging, molding, and cleaning the mixing drum more convenient.

[0042] 3. This low-pressure mixing and molding integrated device features a ring frame with an annular residual material recovery tank inside. A feeding component is located at the bottom of the mixing tank. When the material is fully mixed, the output of the linear motor extends outward, and the sliding pusher moves the feeding nozzle to an outward-facing position. At this point, the solenoid valve is activated, allowing the material inside the mixing tank to flow downward into the mold box. Then, the solenoid valve closes, the linear motor retracts, and the feeding nozzle moves inward. Some residual material drips into the annular residual material recovery tank, thus preventing residual material from contaminating the internal experimental environment during use.

The solenoid valve 5351 is fixedly installed at the bottom end of the cantilever support arm 54 and is connected to the mixing tank 531. The hose 5352 is fixedly installed at the end of the solenoid valve 5351. The feeding nozzle 5353 is fixedly installed at the bottom end of the hose 5352.

The linear motor 5355 is fixedly disposed at the bottom of the cantilever support arm 54, and the output end of the linear motor 5355 is fixedly connected to the sliding pusher 5354.

[0069] Below the cantilever support arm 54, there are parallel linear struts 58. The two ends of the linear struts 58 are fixedly connected to the rotating frame 52 and the vibration motor 59, respectively. A heating support platform 51 is fixedly installed in the middle of the ring frame 61. The rotating frame 52 is rotatably connected to the middle of the heating support platform 51. A rotating motor 57 is fixedly installed on one side of the top of the heating support platform 51. A drive gear 510 and a driven gear 511 are rotatably connected inside the heating support platform 51. The output end of the rotating motor 57 is fixedly connected to the drive gear 510. The driven gear 511 is fixedly sleeved on the outer surface of the heating support platform 51. A sewage tank 64 is fixedly installed on one side of the top of the ring frame 61. A sewage pipe 7 is installed on one side of the bottom of the sewage tank 64. The linear struts 58 and the vibration motor 59 are rotatably connected inside the ring frame 61.

[0070] Working principle: When using this device, the raw materials such as cement, sand, gravel and water are first stored in different weighing and measuring 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 chamber 1 is adjusted. Using the connecting hole 42, the external sealed container 41 is made to be at the same pressure as the inside of the low-pressure sealed chamber 1, thereby creating a constant low-pressure environment for the entire experiment.

[0071] Then, by starting the rotary motor 57, the drive gear 510 meshes with the driven gear 511, thereby driving the rotating frame 52 to rotate, so that the mixing tank 531 moves to the bottom of the corresponding inclined guide pipe 45. At this time, the weighing meter 43 performs quantitative feeding, so that the material falls into the mixing tank 531 through the inclined guide pipe 45. Sand, cement, gravel and water are added in sequence. Then, the mixing motor 534 is started, so that the mixing roller 533 mixes the material in a low-pressure environment.

[0072] When the material is fully mixed, the rotary motor 57 is restarted to move the mixing drum 531 to the top of a set of test mold boxes 62. At this time, the linear motor 5355 is started to push the sliding pusher 5354 outward. The sliding pusher 5354 moves the discharge nozzle 5353 to the outward position. At this time, the solenoid valve 5351 is started, so that the material inside the mixing drum 531 flows downward and falls into the test mold box 62. Then the solenoid valve 5351 is closed, the linear motor 5355 retracts, and moves the discharge nozzle 5353 to the inward position. At this time, some residual material drips into the annular residual material recovery tank 63. Before use, a waterproof membrane is pre-attached in the annular residual material recovery tank 63 so that the residual material falls on the waterproof membrane. After the test, the waterproof membrane and the solidified residual material are collected together.

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

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

[0075] Then the rotary motor 57 is started, causing the mixing drum 531 to move to the top of the next set of test mold boxes 62 for material pouring. After the material is poured, the rotary motor 57 drives the mixing drum 531 to move to the bottom of the weighing meter 43 containing water. At this time, water is injected into the mixing drum 531, and then the mixing roller 533 stirs to clean the remaining material inside. Then the rotary motor 57 drives the mixing drum 531 to the top of the sewage tank 64, and the solenoid valve 5351 is opened to discharge clean water into the sewage tank 64 through the discharge nozzle 5353. The sewage in the sewage tank 64 is finally discharged out through the sewage pipe 7, and then the next set of concrete mixing operations is carried out.

[0076] The entire process is completed within the low-pressure sealed chamber 1, ensuring a constant pressure environment inside the chamber. It also enables the entire process of feeding, mixing, molding, and curing to be completed within the chamber. The entire process is monitored using a visual probe 26, while the internal temperature, humidity, and pressure are monitored in real time using a temperature and humidity sensor 25 and a pressure gauge 24, ensuring that the experimental environment can realistically simulate concrete molding under low pressure.
