Description

Technical Field

[0001] This utility model relates to a stirring device with a calcium aluminate microcrystalline structure control function, belonging to the field of mixing technology. Background Technology

[0002] With the rapid development of materials science and industrial technology, calcium aluminate microcrystalline materials have shown significant application value in various fields such as construction, ceramics, metallurgy, and environmental protection due to their unique physical and chemical properties. Calcium aluminate microcrystals possess excellent properties such as high strength, high temperature resistance, and chemical corrosion resistance, making them a key raw material for manufacturing high-performance composite materials, refractory materials, and functional ceramics.

[0003] However, traditional calcium aluminate microcrystal preparation techniques have significant limitations. Controlling the crystal structure is crucial during microcrystal formation, as it directly determines the final material properties. Traditional stirring equipment struggles to provide uniform temperature and material distribution during mixing and reaction, leading to uneven crystal growth, difficulty in controlling crystal size and morphology, low stirring efficiency, insufficient material mixing, long reaction times, high energy consumption, and low production efficiency. Furthermore, the lack of control over the microcrystal formation process results in significant batch-to-batch performance variations and difficulty in ensuring consistency.

[0004] Therefore, developing a stirring device capable of controlling the microcrystalline structure of calcium aluminate is of great significance for improving product quality, reducing production costs, and meeting the demands of the high-end market. Utility Model Content

In this utility model, unless otherwise expressly specified and limited, the terms "installed," "connected," "linked," and "fixed," etc., should be interpreted broadly. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figures 1-3 The illustrated stirring device with calcium aluminate microcrystalline structure control function includes a support 1 and a stirring tank 2. The stirring tank 2 is mounted on the support 1. The stirring tank 2 includes a heat insulation layer 201, a heat insulation layer 202, a heat conduction layer 203, and a heat transfer coil 204. The heat transfer coil 204 is installed between the heat insulation layer 202 and the heat conduction layer 203, and abuts against the heat conduction layer 203. The heat insulation layer 201 is located on the outermost layer of the stirring tank 2, and its main function is to isolate the influence of the external ambient temperature on the temperature of the material inside the tank, preventing external temperature from entering or internal temperature from dissipating. The heat insulation layer 202 is a key part of the stirring tank 2 and is usually made of a material with low thermal conductivity to effectively reduce temperature transfer and maintain the temperature stability of the material inside the tank. The heat conduction layer 203 has good thermal conductivity and is generally made of stainless steel, which can quickly transfer the temperature in the heat transfer coil 204 to the stirring tank 2. The heat transfer coil 204 is made of copper and achieves heat exchange with the material in the mixing tank 2 through close contact with the heat-conducting layer 203.

[0025] A top cover 4 is installed on the top of the mixing tank 2. The top cover 4 includes a conveying section, which includes a conveying bend 401 and a gas collecting hood 403. The conveying bend 401 is connected to the gas collecting hood 403. A stirring motor 5 is installed on the top cover 4. The stirring motor 5 is connected to a stirring paddle 207, which drives the stirring paddle 207 to stir the materials. The top cover 4 also has a feed inlet 404 for the raw materials to enter the mixing tank 2. A temperature sensor 206 is installed at the lower end of the top cover 4 to monitor the temperature inside the mixing tank 2.

[0026] The lower end of the conveying bend 401 is provided with a second venturi tube 40101 and a sliding cavity 40102. The second venturi tube 40101 and the sliding cavity 40102 are connected. A conveying butterfly valve 402 is provided above the second venturi tube 40101 in the conveying bend 401.

[0027] The mixing tank 2 is located on one side of the conveying bend 401 and has a mixing tank inlet 205. A control component 3 is installed at one end of the mixing tank inlet 205 and the other end of the mixing tank inlet 205 is connected to the temperature transfer coil 204. The control component 3 is connected to the cold water pipe and the hot water pipe. The control component 3 includes a conversion block 301. A switch rod 306 is provided between the conversion block 301 and the conveying bend 401. One end of the switch rod 306 is slidably connected to the conversion block 301 and the other end of the switch rod 306 is slidably connected to the conveying bend 401. The switch rod 306 is used to control the conversion between cold and hot water in the control component 3.

[0028] The conversion block 301 includes a heat exchange port 30102 and a hot water inlet 30101, a cold water inlet 30103, and a first Venturi tube 30104, all connected to the heat exchange port 30102. The control component 3 includes a hot water pipe 303 and a cold water pipe 304. The hot water pipe 303 is equipped with a hot water pipe butterfly valve 302, and the cold water pipe 304 is equipped with a cold water pipe butterfly valve 305. The hot water pipe 303 is connected to the hot water inlet 30101, and the cold water pipe 304 is connected to the cold water inlet 30103. The first Venturi tube 30104 is connected to the mixing tank inlet 205. The hot water pipe 303 is connected to a hot water source, and the cold water pipe 304 is connected to a cold water source.

[0029] The switch rod 306 includes a connecting rod 30603. One end of the connecting rod 30603 is provided with a switch plug 30601, and the other end of the connecting rod 30603 is provided with a sliding plug 30604. The switch plug 30601 is located inside the heat exchange hole 30102 and is slidably connected to the heat exchange hole 30102. The sliding plug 30604 is located inside the sliding cavity 40102 and is slidably connected to the sliding cavity 40102. A switch spring 30602 is sleeved on the section of the connecting rod 30603 located in the heat exchange hole 30102. One end of the switch spring 30602 is fixedly connected to the top of the heat exchange hole 30102, and the other end of the switch spring 30602 is fixedly connected to the switch plug 30601.

[0030] The mixing tank 2 includes a water outlet 208 and a material discharge port 209. A water outlet butterfly valve 6 is installed on the water outlet 208, and a material discharge butterfly valve 7 is installed on the material discharge port 209.

[0031] Both the first Venturi tube 30104 and the second Venturi tube 40101 include a contraction section, a throat, and an expansion section. In the control component 3, when cold water or hot water flows through the first Venturi tube 30104, the cross-sectional area of ​​the pipe gradually decreases in the contraction section, and the velocity of the cold water or hot water begins to increase. When the cold water or hot water reaches the throat, the flow velocity reaches its maximum value in the throat section with the smallest cross-sectional area, so that the cold water or hot water flows quickly through the inlet 205 of the mixing tank into the heat transfer coil 204. When the material in the mixing tank 2 is heated to a certain temperature, a large amount of hot air is generated inside the mixing tank 2. To avoid wasting the hot air and improve energy utilization, a conveying section is provided on the top cover 4. When the hot air flows through the second venturi tube 40101, the principle is the same as when cold or hot water flows through the first venturi tube 30104. After the hot air is accelerated, the high-speed airflow generated generates kinetic energy to push the sliding plug 30604 in the sliding cavity 40102 downward, causing the switch rod 306 to move downward, thereby driving the switch plug 30601 to move downward in the heat exchange hole 30102 to open the cold water inlet 30103. When cold water is not needed in the mixing tank 2, the switch plug 30601 is located above the heat exchange hole 30102, blocking the cold water inlet 30103. The hot water inlet 30101 is connected to the first venturi tube 30104.

[0032] The working process of a stirring device with calcium aluminate microcrystalline structure control function is as follows:

[0033] Material enters the mixing tank 2 through the feed inlet 404. The hot water pipe butterfly valve 302 is opened, and hot water enters the hot water inlet 30101 through the hot water pipe 303. The hot water flows through the heat exchange hole 30102 and the first venturi tube 30104 and quickly enters the heat transfer coil 204 to start heating the material in the mixing tank 2. At the same time, the stirring motor 5 drives the stirring paddle 207 to stir the material. The temperature sensor 206 monitors the temperature in the mixing tank 2 in real time. When the temperature does not meet the requirements, hot water continues to be supplied. The temperature sensor 206 sends a signal to the outlet butterfly valve 6, and the outlet 208 is opened, so that the water in the heat transfer coil 204 with a lower temperature is discharged from the outlet 208, ensuring that the heating temperature in the mixing tank 2 is stable.

[0034] When the material is stirred and heated to the required temperature, the hot water pipe butterfly valve 302 closes and the conveying butterfly valve 402 opens. The hot air in the mixing tank 2 enters the lower part of the conveying bend 401 through the gas collecting hood 403. The hot air flows through the second venturi tube 40101. The thrust generated by the hot air drives the sliding plug 30604 in the sliding cavity 40102 to move downward, causing the switch rod 306 to move downward. This causes the switch plug 30601 to move downward in the heat exchange hole 30102, thereby opening the cold water inlet 30103. The switch plug 30601 blocks the hot water inlet 30101, and the cold water inlet 30103 is connected to the first venturi tube 30104. The cold water pipe butterfly valve 305 opens, and the cold water flows from the cold water inlet 30103 through the heat exchange hole 30102 and the first venturi tube 30104 into the heat transfer coil 204, starting to rapidly cool the material in the mixing tank 2. Temperature sensor 206 monitors the temperature inside the mixing tank 2 in real time. When the temperature reaches the point where the desired calcium aluminate microcrystalline structure can be precipitated, cooling is stopped, stirring paddle 207 stops stirring, cold water pipe butterfly valve 305 closes, conveying butterfly valve 402 closes, switch spring 30602 drives switch rod 306 to reset, discharge butterfly valve 7 opens, and material is discharged from discharge port 209.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
