Description

Technical Field

[0001] The present invention relates to the field of cooling technology, in particular to cooling equipment and a method for producing and preparing aluminum oxide. Background Art

[0002] Alumina is an inorganic substance with the chemical formula Al2O3. It is a high-hardness compound with a melting point of 2054°C and a boiling point of 2980°C. It is an ionic crystal that can be ionized at high temperatures and is often used to make refractory materials.

[0003] Alumina needs to be calcined at high temperature during the preparation process. The batched raw materials are sent to calcination equipment such as rotary kilns for high-temperature calcination. In the rotary kiln, the material moves forward continuously with the rotation of the kiln body, and at the same time fully exchanges heat with the high-temperature airflow generated by combustion. The material undergoes a series of complex physical and chemical changes at high temperatures, gradually forming alumina clinker. After the calcined alumina clinker is discharged from the rotary kiln, it needs to be cooled. Through cooling, the clinker temperature is reduced to a temperature range that is convenient for subsequent processing, and it also helps to improve the physical properties and chemical stability of the clinker.

[0004] At present, it is cooled by cooling equipment, but after the aluminum oxide is exported, there are single-drum coolers, multi-drum coolers, etc. During the cooling process, the material needs to be exported and can only be introduced into the next process after cooling.

DETAILED DESCRIPTION

[0033] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components to avoid unnecessary confusion of the concepts of the present invention.

[0034] See also Figure 1 A cooling device for the production and preparation of alumina is mainly composed of a body 1, a circulating guide rail 2, a heat sink 3, a bracket 4, a linear module 5, a lower hopper 6, an air guide component 7, a support beam 8 and an air outlet component 9.

[0035] The body 1 is the basic supporting structure of the whole device and is made of solid metal material, such as high-quality carbon steel or stainless steel, to ensure the stability of the device during long-term operation. The circulation rails 2 are installed at the front and rear ends of the body 1 to provide track support for the circulation movement of the heat dissipation platform 3.

[0036] See also Figure 2 , circulating guide rails 2 are respectively installed at the front and rear ends of the machine body 1, and the circulating guide rails 2 are used to drive the heat dissipation platform 3 to move around the machine body 1 in a cyclic and fixed-distance manner. The circulating guide rails 2 include four toothed belt pulleys 21 arranged at the front and rear ends of the machine body 1, and the four toothed belt pulleys 21 are synchronously driven by two transmission shafts to ensure the stability and synchronization of the operation. The toothed belt pulleys 21 at the front and rear ends of the machine body 1 are driven by a toothed belt 22, and the toothed belt 22 has high strength and wear resistance, and can ensure long-term stable operation. Tracks 23 are also installed at the front and rear ends of the machine body 1, and several groups of moving platforms 24 are evenly distributed on the track 23. The bottom end of the moving platform 24 is connected to the toothed belt 22 through a support foot, and the heat dissipation platform 3 is installed between the moving platforms 24 at the front and rear ends of the machine body 1. When the toothed belt pulley 21 rotates, it drives the toothed belt 22 and the moving platform 24 thereon to move at a fixed distance, so that all the moving platforms 24 pass under the lower hopper 6 in turn, and the cyclic switching of the heat dissipation platform 3 is realized.

[0037] The bracket 4 is mounted on the machine body 1, and its two legs are firmly mounted on the front and rear ends of the machine body 1, respectively, to provide support for the linear module 5 and the lower hopper 6. The bracket 4 is made of high-quality aluminum alloy, which not only ensures the structural strength but also reduces the overall weight. The linear modules 5 are installed on the two inner sides of the bracket 4. The linear modules 5 are high-precision and high-load models. The slide is connected to the lower hopper 6. Through the drive of the linear module 5, the lower hopper 6 can move back and forth accurately on the heat sink 3, and the alumina clinker powder is evenly introduced into each heat sink 3 passing through.

[0038] See also Figure 4 , Figure 5 and Figure 6 The heat sink 3 includes a rectangular plate 31, which is made of an aluminum alloy with good thermal conductivity and can quickly transfer heat. A rectangular groove 32 is provided at the top of the rectangular plate 31, and a heat sink 33 is installed inside the rectangular groove 32. The heat sink 33 includes a substrate 331 and equidistantly distributed A fins 332 installed on the substrate 331. Alumina clinker powder is introduced between the A fins 332 to increase the heat dissipation area and achieve rapid cooling. Several groups of equidistantly distributed B fins 333 are installed at the bottom of the substrate 331 to further enhance the heat dissipation effect.

[0039] An A air guide block 34 and a B air guide block 35 are respectively installed at both ends of the heat sink 33. The A air guide block 34 and the B air guide block 35 are connected to the heat dissipation area of ​​the heat sink 33, and ports are provided at the bottom of the A air guide block 34 and the top of the B air guide block 35. When forced air cooling is performed, the external fan guides the wind into the A air guide block 34 through the air guide assembly 7, and the A air guide block 34 evenly distributes the wind to each B fin 333 to take away the heat, and then the heat is exported through the B air guide block 35 to achieve efficient heat dissipation. It cools down by wind without affecting the transportation of alumina clinker powder, and does not take back the alumina clinker powder.

[0040] For example, during the cooling process, the cold air provided by the air cooling system enters through the A air guide block 34 , passes between the B fins 333 , takes away the heat, and then is output from the B air guide block 35 .

[0041] The discharged alumina clinker powder is continuously transported by the circulating guide rail 2 and continuously cooled by the multiple heat dissipation platforms 3. The alumina clinker powder is cooled and radiated during the process of being transported to the next link, which does not affect the further processing of the alumina clinker powder.

[0042] See also Figure 3The lower hopper 6 includes a guide tube 61 installed between two linear modules 5. The guide tube 61 is made of high temperature resistant and corrosion resistant stainless steel to ensure that the aluminum oxide clinker powder will not be affected by high temperature and chemical corrosion when conveying. A retractable guide hopper 62 is provided at the bottom of the guide tube 61. The guide hopper 62 can fall down and contact the heat sink 3 under the action of gravity, so as to facilitate the introduction of the aluminum oxide clinker powder into the heat sink 3. A electromagnet 63 is installed at the bottom of both sides of the guide tube 61, and iron sheets 64 are provided at the top of both sides of the guide hopper 62. When the A electromagnet 63 is powered off, the guide hopper 62 falls down under the action of gravity and is in close contact with the heat sink 3. At this time, the linear module 5 drives the guide hopper 62 to move back and forth on the heat sink 3 to evenly introduce the aluminum oxide clinker powder into the heat sink 3. When the A electromagnet 63 is energized, a strong magnetic field is generated to absorb the iron sheet 64 on the guide hopper 62, so that the guide hopper 62 moves up and docks with the guide pipe 61, completing a material unloading operation and switching the heat sink 3 to wait for the next material unloading.

[0043] When the material guide hopper 62 moves on the rectangular plate 31 to guide the material, the material is introduced between the A fins 332. The thermal conductivity of the heat sink 33 allows the wind to cool the B fins 333, thereby preventing the wind from directly blowing away the alumina clinker powder. The hopper has a good cooling function, and a material control discharger is preferably installed on the lower hopper 6 to control the amount of material introduced into the lower hopper 6 each time.

[0044] See also Figure 7 and Figure 8 The air guide assembly 7 is located at the top of the body 1, and includes a plurality of groups of equally spaced air guide nodes 71, which are connected by hoses 72, and the end air guide nodes 71 are connected to the fan through a pipeline. An air guide port 73 is provided at the top of the air guide node 71, and an A ring-shaped electromagnet 74 is installed at the top, and a guide column 75 is installed at the bottom, and the guide column 75 is slidably connected to the body 1. When the heat sink 3 stops at a specified position, the A ring-shaped electromagnet 74 is energized to generate a strong annular magnetic field, which is adsorbed on the bottom of the heat sink 3, so that the air guide node 71 is connected to the heat sink 3. The fan guides the wind into the heat sink 3 through the air guide assembly 7 to achieve forced air cooling. When the A ring-shaped electromagnet 74 is powered off, the air guide node 71 automatically falls under gravity, and its displacement is prevented by the guide column 75.

[0045] A sealing gasket is provided at the top of the air guide port 73. When the air guide node 71 is connected to the bottom port of the A air guide block 34, the air guide port 73 is sealed with the bottom of the A air guide block 34 through the sealing gasket. The shape of the air guide port 73 is as follows: Figure 8 As shown, the bottom port of the A air guide block 34 is circular. Since there is an error in the movement of the circulation guide rail 2, it cannot be accurately aligned. Therefore, the air guide port 73 can directly wrap the bottom port of the A air guide block 34 to guide the wind into the heat dissipation platform 3 for cooling.

[0046] See also Fig. 9 The air outlet assembly 9 is arranged at the bottom end of the support beam 8, and includes an air outlet cover 91 connected to the pipe on the support beam 8 through a pipe. Two spring buffer rods 92 are installed between the air outlet cover 91 and the support beam 8 to play the role of buffering and adjusting the height. A B-ring electromagnet 93 is installed at the bottom end of the air outlet cover 91. When the B-ring electromagnet 93 is powered on, it is adsorbed on the top of the heat sink 3, so that the heat conducted by the heat sink 3 is smoothly conducted through the air outlet cover 91, completing the heat dissipation process. When the B-ring electromagnet 93 is powered off, the two spring buffer rods 92 are stretched and automatically reset, so that the B-ring electromagnet 93 moves up, thereby separating from the heat sink 3.

[0047] The bottom end of the B annular electromagnet 93 is also provided with a sealing gasket, which has the same shape as the air guide port 73. When docking with the top end of the B air guide block 35, it wraps it to prevent air leakage, and the heat can be collected and utilized after being discharged through the air outlet cover 91.

[0048] The air guide component 7 and the air outlet component 9 fall off from the heat sink 3 during the operation of the circulation guide rail 2. When the indirect operation of the circulation guide rail 2 stops, the air guide component 7 and the air outlet component 9 dock with all the heat sinks 3 in the area to cool down. They are repeatedly detached from and docked with the heat sink 3 many times, and each time they dock, the heat sink 3 moved to the area is cooled down. In this way, each heat sink 3 is cooled down multiple times without affecting the transportation.

[0049] The equipment is installed between the rotary kiln and the next process. The material discharged from the rotary kiln is moved through the equipment and cooled during the movement. After cooling, it is introduced into another process, which can reduce the processing steps.

[0050] A cooling method for the production and preparation of aluminum oxide, with specific operating steps:

[0051] 1. Cutting operation

[0052] The drive motor of the circulating guide rail 2 is started, and the motor drives the transmission shaft to rotate the four toothed belt wheels 21 synchronously, thereby driving the toothed belt 22 and the moving platform 24 to move at a fixed distance. The circulating guide rail 2 adopts an indirect operation mode, that is, it pauses after each movement of a certain distance, so that the heat dissipation platform 3 is switched to the bottom of the lower hopper 6 in turn.

[0053] When the heat sink 3 below the lower hopper 6 is in place, the A electromagnet 63 is controlled to be de-energized, and the guide hopper 62 falls down under the action of gravity and contacts the heat sink 3 .

[0054] The linear module 5 is started, and the linear module 5 drives the lower hopper 6 to move back and forth on the heat dissipation platform 3 to evenly introduce the alumina clinker powder into between the A fins 332 in the heat dissipation platform 3 .

[0055] When the material in the lower hopper 6 is completely introduced, the A electromagnet 63 is energized, the guide hopper 62 moves up to dock with the guide pipe 61, and the heat sink 3 continues to move along the circulation guide rail 2, waiting for the next material discharge. In this way, the alumina clinker powder is evenly distributed on each heat sink 3.

[0056] (II) Cooling operation

[0057] When the heat sink 3 moves to the cooling position along with the circulation guide rail 2 and stops, the A annular electromagnet 74 of the air guide assembly 7 is energized, and the air guide node 71 is adsorbed on the bottom end of the heat sink 3 under the action of magnetic force, so that the air guide port 73 is docked with the port A of the air guide block 34 of the heat sink 3.

[0058] At the same time, the B annular electromagnet 93 of the air outlet assembly 9 is energized, and the air outlet cover 91 is adsorbed on the top of the heat sink 3 under the action of the spring buffer rod 92, and docks with the port B of the air guide block 35 of the heat sink 3.

[0059] Start the fan, and the wind generated by the fan is introduced into the heat sink 3 through the air guide port 73 of the air guide component 7. The cold air is distributed between the B fins 333 through the A air guide block 34, taking away the heat of the heat sink 33 and the alumina clinker powder. The hot air enters the air outlet cover 91 of the air outlet component 9 through the B air guide block 35, and is finally discharged from the equipment to achieve forced air cooling and heat dissipation.

[0060] (III) Circulation cooling

[0061] When the heat sink 3 completes one cooling, the circulating guide rail 2 starts again, driving the heat sink 3 to continue moving.

[0062] As the heat sink 3 moves, the A annular electromagnet 74 of the air guide assembly 7 is powered off, and the air guide node 71 is separated from the heat sink 3; the B annular electromagnet 93 of the air outlet assembly 9 is powered off, and the air outlet cover 91 is separated from the heat sink 3.

[0063] In this way, the cycle is repeated to cool down each heat sink 3 passed by, thereby achieving continuous cooling of the alumina clinker powder.

[0064] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
