Description

Technical Field

[0001] The present application relates to the field of calcium aluminate production equipment, and in particular to a calcium aluminate discharge cooling device. Background Art

[0002] Calcium aluminate is an off-white powder. Its main components are a mixture of calcium dialuminate (CaO·2Al2O3) and calcium monoaluminate (CaO·Al2O3). It is slightly soluble in water, and its aqueous solution is alkaline, with a pH of approximately 11. Calcium aluminate is primarily used in the production of aluminum salts such as polyaluminum chloride, aluminum sulfate, and sodium aluminate. It is also used to adjust the alkalinity and is used in refractory materials.

[0003] When producing calcium aluminate, the calcined calcium aluminate powder needs to be cooled. When natural cooling is used, there are problems such as long cooling time and low cooling efficiency. When air cooling is used, the calcium aluminate powder is easily scattered.

[0017] Below, the present application is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] like Figure 1-2As shown, the calcium aluminate discharge cooling device is located above the discharge conveyor belt 1 and includes a housing 2. A pair of water-permeable plates 3 are provided within the housing 2. Cooling water is stored between the water-permeable plates 3 and the inner wall of the housing 2. A fan 4 is provided between the pair of water-permeable plates 3. The fan 4 is disposed at the inner bottom of the housing 2. Cooling water seeps from one side of the water-permeable plates 3 to the other side of the water-permeable plates 3 and flows into the fan 4. The fan 4 blows an airflow carrying the cooling water toward the top of the discharge conveyor belt 1. When the cooling water seeps from the water-permeable plates 3, it flows onto the blades of the fan 4. As a result, when the blades of the fan 4 rotate and generate airflow, the cooling water is entrained in the airflow and blown toward the discharge conveyor belt 1. While achieving air cooling on the material on the discharge conveyor belt 1, the cooling water can directly reduce the temperature of the material secondary. Moreover, the cooling water can increase the humidity of the material, preventing the material from being scattered by the airflow, effectively improving the cooling effect and the operating environment.

[0019] A sleeve 21 is provided at the center of the bottom of the housing 2. The bottom of the sleeve 21 is flush with the outer bottom of the housing 2, and the top of the sleeve 21 is located above the inner bottom of the housing 2. The fan 4 is disposed within the sleeve 21. A creepage gap exists between the outer wall of the sleeve 21 and the pair of water-seepage plates 3. The provision of the sleeve 21 facilitates the installation and fixation of the fan 4. Furthermore, due to the creepage gap between the sleeve 21 and the water-seepage plates 3, when cooling water passes through the water-seepage plates 3 and flows into the creepage gap, the cooling water automatically creeps upward under capillary action and falls into the inner side of the sleeve 21, thereby facilitating the control of the flow of cooling water and ensuring that an excessive amount of cooling water does not flow into the fan 4. This also makes the amount of cooling water entrained in the airflow blown out by the fan 4 more controllable, thereby preventing excessive cooling water from being sprayed onto the material, causing it to become excessively moist.

[0020] The top outer side of the sleeve 21 is provided with a slope 210, and the distance between the slope 210 and the water seepage plate 3 gradually decreases from top to bottom. By setting the slope 210, the size of the creepage gap can be optimized, thereby ensuring that the cooling water can climb into the sleeve 21 evenly.

[0021] An overflow plate 5 is provided between the seepage plate 3 and the inner wall of the housing 2. The height of the overflow plate 5 is less than that of the seepage plate 3, and the distance between the overflow plate 5 and the seepage plate 3 is less than the distance between the overflow plate 5 and the inner wall of the housing 2. The cooling water is located between the overflow plate 5 and the inner wall of the housing 2. The provision of the overflow plate 5 controls the contact area between the cooling water and the seepage plate 3, effectively preventing the cooling water from excessively infiltrating the side of the seepage plate 3 facing the sleeve 21. This ensures that the cooling water can reliably suppress the flying and drifting of materials without causing excessive increase in the humidity of the materials.

[0022] A water pressure block 22 is provided between the overflow plate 5 and the inner wall of the shell 2, and a driving mechanism 6 is provided on the top of the shell 2. The driving mechanism 6 is used to drive the water pressure block 22 to move up and down between the overflow plate 5 and the inner wall of the shell 2. Initially, the liquid level of the cooling water is the same as the top height of the overflow plate 5. At this time, the driving mechanism 6 drives the water pressure block 22 to move downward and makes the water pressure block 22 contact with the cooling water. In this way, the cooling water will overflow the overflow plate 5 and enter between the overflow plate and the seepage plate 3. Since the gap between the overflow plate 5 and the seepage plate 3 is relatively small, the contact area between the same volume of cooling water and the seepage plate 3 becomes larger, thereby increasing the area of the seepage plate 3 that produces water seepage, effectively increasing the air humidity above the fan 4, ensuring that the airflow reliably dissipates heat for the material, and effectively preventing the material from floating around during the cooling process by increasing the humidity of the material.

[0023] The thickness of the water pressure block 22 is less than the distance between the overflow plate 5 and the inner wall of the housing 2, and the height of the water pressure block 22 is less than the height of the overflow plate 5. This maximizes the storage capacity of cooling water within the housing 2, ensuring sufficient cooling water for increasing the humidity of the material. Furthermore, by reducing the distance between the overflow plate 5 and the seepage plate 3, the area of the seepage plate 3 involved in water seepage is significantly increased, thereby increasing the humidity of the air above the fan 4 and ensuring that the material does not float around when the fan 4 dissipates heat from the material.

[0024] The drive mechanism 6 includes a motor 61, a transmission shaft 62, and a pull rope 63. The motor 61 is mounted on the top of the housing 2 and is used to drive the transmission shaft 62 to rotate. The transmission shaft 62 is provided with a plurality of winding rollers 64. One end of the pull rope 63 is wound around the winding rollers 64, and the other end of the pull rope 63 is connected to the water pressure block 22. When the motor 61 drives the transmission shaft 62 to rotate in the forward direction, the winding rollers 64 on the transmission shaft 62 rotate simultaneously. In this way, the pull rope 63 is continuously wound away from the winding shaft, thereby allowing the water pressure block 22 to move downward. When the motor 61 drives the transmission shaft 62 to rotate in the reverse direction, the pull rope 63 is continuously wound toward the winding shaft, thereby allowing the water pressure block 22 to move upward. When the water pressure block 22 moves downward, the cooling water is continuously pressed into the space between the overflow plate 5 and the seepage plate 3, and then slowly seeps through the seepage plate 3 toward the sleeve 21. When the water pressure block 22 is displaced to the lowest position, the cooling water in the shell 2 will not be able to overflow to the outside of the overflow plate 5. At this time, the water pressure block 22 can be moved upward and reset, thereby facilitating the replenishment of cooling water.

[0025] The motor 61 is mounted on one side of the top of the housing 2, and a bearing seat 23 is mounted on the other side of the top of the housing 2. One end of a transmission shaft 62 is connected to the output shaft of the motor 61, and the other end of the transmission shaft 62 is inserted into the bearing seat 23. The support provided by the bearing seat 23 ensures that the transmission shaft 62 can reliably rotate about its axis under the drive of the motor 61, thereby driving the water pressure block 22.

Any non-substantial changes and replacements made by technicians in this field based on the present application shall fall within the scope of protection required by the present application.
