[0002] The red mud-based cementitious material hydration performance detection device is a tool used to evaluate the performance and characteristics of red mud-based cementitious materials during the hydration process. Red mud-based cementitious materials are a special type of cementitious material. They react with water to form a colloid-like substance with a certain viscosity and plasticity. They are often used in the fields of construction, geological engineering, etc. The existing cement hydration heat measuring instrument (Announcement No.: CN211179608U) has the following disadvantages in use:

[0003] During use, the raw materials to be tested are placed in a test tank, and then the stirring motor is started to drive the stirring paddle to rotate and stir. Finally, the test results are calculated according to the temperature change of the thermometer. However, during the stirring process, the tested raw materials will have some friction with the surface of the thermometer, which may cause damage to the thermometer for a long time, thereby affecting the detection effect of the thermometer. For this reason, this patent proposes a red mud-based cementitious material hydration performance detection device to solve the above problem. Utility Model Content

[0019] The red mud-based cementitious material hydration performance detection device is a tool for evaluating the performance and characteristics of the red mud-based cementitious material during the hydration process. The red mud-based cementitious material hydration performance detection device provided by the utility model calculates the test result through the temperature change of the thermometer 9. In the process of using this equipment for detection operations, it is necessary to ensure in advance that the first motor, the second motor 603 and the third motor can work normally, so as to ensure the normal operation of the equipment.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a red mud-based gelling material hydration performance detection device, comprising a box body 1, a fixing plate 8 is fixed between the inner walls of both sides of the box body 1, two test boxes 7 are plugged into the fixing plate 8, a box cover 2 is plugged into the top of the box body 1, a first moving mechanism 3 is arranged on the top of the box cover 2, two support frames 302 are fixed on the top of the first moving mechanism 3, a first screw rod 301 is rotatably connected between the inner walls of the top of the two support frames 302 and the top of the box cover 2, and a first slider is screwed on the outer wall of the first screw rod 301 A first connecting frame 303 is fixed to one side of the first slider. After the first connecting frame 303 passes through the box cover 2, a fixing frame 304 is fixed to the bottom end thereof. A connecting sleeve 305 is slidably connected to one side of the fixing frame 304. Connecting strips 306 are fixed to both ends of the fixing frame 304. The connecting sleeve 305 is slidably connected to the connecting strip 306. A sliding groove 307 is provided on the connecting sleeve 305. A sliding strip 308 is slidably connected in the sliding groove 307. A thermometer 9 is fixed to the top of the fixing frame 304. A second moving mechanism 6 is provided between the inner walls of both sides of the box cover 2. The second moving mechanism 6 includes a second screw rod 601 that is rotatably connected between the inner walls of both sides of the box cover 2. The second screw rod 601 is a double-headed screw rod. The outer walls of both ends thereof are screwed with a second slider 602. The second slider 602 is fixed to the sliding strip 308. A second motor 603 is fixed to one side of the box cover 2. The output end of the second motor 603 passes through the box cover 2 and is fixed to the second screw rod 601. After the first screw rod 301 passes through the support frame 302, a rotating wheel is fixed on its outer wall, and a belt is arranged between the two rotating wheels. A mounting frame is fixed to the top of one of the support frames 302, and a first motor is fixed to the top of the mounting frame. The output end of the first motor passes through the mounting frame and is fixed to the top of one of the rotating wheels.

[0021] It should be noted that, one of the rotating wheels is driven to rotate by the first motor, and the rotating wheel drives the belt to move and then drives the first screw rod 301 to rotate. The rotation of the first screw rod 301 drives the first slider to move, and then drives the first connecting frame 303 to move so that the thermometer 9 moves downward. After moving to the moving distance, the second motor 603 is started, and the second motor 603 drives the second screw rod 601 to rotate, so that the two second sliders 602 move away from each other and drive the two connecting sleeves 305 to move away from each other, so that the thermometer 9 is no longer blocked by the connecting sleeve 305 and the fixing frame 304. In this way, the hydration performance of the red mud-based cementitious material in the test box 7 can be tested. The bottom end of the box cover 2 is rotatably connected to two rotating rods, and multiple stirring rods are fixed on the outer walls of the two rotating rods. Two third motors are fixed to the top of the box cover 2. The output ends of the two third motors pass through the box cover 2 and are fixed to the tops of the rotating rods.

[0022] like Figure 2 As shown, a water inlet 5 is fixedly connected to one side of the box 1, and a water outlet is fixedly connected to one end of the box 1, and a valve is installed on the water outlet. A heating pipe is installed in the box 1, and a temperature sensor is installed in the box 1. A controller 4 is installed on the box cover 2, and the controller 4 is electrically connected to the first motor, the second motor 603, the third motor, the thermometer 9, the temperature sensor and the heating pipe.

[0023] It should be noted that the rotating rod is driven to rotate by the third motor, and the rotating rod drives the stirring rod to rotate to stir the red mud-based gelling material. After the stirring is completed, the temperature can be detected by the thermometer 9. In addition, the heating pipe heats the water in the box 1. When it is heated to a suitable temperature, the temperature is transmitted to the controller 4 by the temperature sensor, thereby changing the heating power of the heating pipe, and a predetermined amount of red mud-based gelling material is added to the two test boxes 7 respectively to detect it.

[0024] Working principle: the third motor is started by the controller 4 so that the stirring rod stirs the red mud-based gelling materials in the two test boxes 7. After stirring, the first motor is started by the controller 4 to drive one of the wheels to rotate, and the wheel drives the belt to move and then drives the first screw rod 301 to rotate. The rotation of the first screw rod 301 drives the first slider to move, and then drives the first connecting frame 303 to move so that the thermometer 9 moves downward. After moving to the moving distance, the second motor 603 is started by the controller 4, and the second motor 603 drives the second screw rod 601 to rotate, so that the two second sliders 602 move away from each other, driving the two connecting sleeves 305 to move away from each other, so that the thermometer 9 is no longer blocked by the connecting sleeve 305 and the fixing frame 304, so that the hydration performance of the red mud-based gelling materials in the test box 7 can be tested.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
