Technical Field

[0001] This utility model belongs to the field of aluminum ash denitrification technology, specifically an energy-saving aluminum ash denitrification reaction tank. Background Technology

[0002] Aluminum ash is formed from slag produced during aluminum electrolysis and aluminum smelting after cooling or subsequent processing. In addition, the aluminum content in slag from different sources is different. Based on the different aluminum content, aluminum ash can be divided into primary aluminum ash and secondary aluminum ash. The harmless and resource-based disposal of aluminum ash first requires the separation of salts in the aluminum ash and the denitrification of aluminum nitride.

[0003] In existing technologies, aluminum ash is usually denitrified by adding it to a reaction tank along with a reducing agent for heating and denitrification. However, the position of the sealing plate cannot be adjusted during heating and denitrification in the reaction tank, requiring manual adjustment and control for sealing and feeding, which is time-consuming and labor-intensive, reducing the practicality of the device. Furthermore, it is not possible to rinse and clean the debris on the inner wall of the reaction tank during use, making it inconvenient for future use.

[0004] Therefore, an energy-saving aluminum ash denitrification reaction tank is proposed to address the above problems. Utility Model Content

The radius of the spiral conveying blade is the same as the inner radius of the reaction tank body.

[0009] Preferably, the cleaning mechanism includes a high-pressure water pump. The high-pressure water pump is fixedly installed at the top of one side of the reaction tank body.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Specific implementation examples are given below.

[0034] Please see Figures 1 to 2 This utility model provides an energy-saving aluminum ash denitrification reaction tank, including a support base 1, a reaction tank body 2 is bolted to the upper end of the support base 1, and multiple heating wires are installed inside the reaction tank body 2. A mixing mechanism 3 is installed in the middle of one side of the reaction tank body 2, a cleaning mechanism 4 is installed at the top of one side of the reaction tank body 2, and a feed inlet 5 is fixedly installed on one side of the upper end of the reaction tank body 2.

[0035] A support plate 6 is provided on one side of the feed inlet 5, and an angle adjustment mechanism 7 is provided at the lower end of the support plate 6. A frame 8 is fixedly installed on the other side of the upper end of the reaction tank body 2, and an absorption mechanism 9 is fixedly installed at the upper end of the frame 8. A discharge pipe is provided on the other side of the reaction tank body 2, and the discharge pipe is not shown in the figure.

[0036] like Figure 1 , Figure 2 and Figure 3As shown, the mixing mechanism 3 includes a motor 31. The motor 31 is fixedly installed in the middle of one side of the reaction tank body 2. The output end of the motor 31 is splined connected to a rotating rod 32. One end of the rotating rod 32 passes through one side of the reaction tank body 2 and is connected to a transmission rod 33. The transmission rod 33 is located inside the reaction tank body 2. The surface of the transmission rod 33 is provided with a spiral conveying blade 34. The radius of the spiral conveying blade 34 is consistent with the inner radius of the reaction tank body 2.

[0037] During operation, aluminum ash and reducing agent are heated into the main body 2 of the reaction tank, which then automatically heats up. During heating, the motor 31, powered by an external power source, drives the rotating rod 32 to rotate, which in turn drives the transmission rod 33 to rotate, which in turn drives the spiral conveyor blade 34 to rotate. This process achieves uniform mixing and heating of the internal components, thereby improving the denitrification efficiency.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, the cleaning mechanism 4 includes a high-pressure water pump 41. The high-pressure water pump 41 is fixedly installed on the top of one side of the reaction tank body 2. A first water pipe 42 is connected to one side of the high-pressure water pump 41. A water pipe connector 43 is connected to one end of the first water pipe 42. A second water pipe 44 is connected to the other side of the high-pressure water pump 41. One end of the second water pipe 44 passes through the reaction tank body 2 and is located at the top of the inner part of the reaction tank. Multiple spray heads 45 are provided at the lower end of the second water pipe 44. Both the second water pipe 44 and the spray heads 45 are made of high-temperature resistant material.

[0039] During operation, after repeated or single use, the inner wall of the reaction tank body 2 becomes contaminated with debris. The water pipe connector 43 is then connected to the water source pipe, and the high-pressure water pump 41 draws water into the first water pipe 42. The water is then transported through the first water pipe 42 to the second water pipe 44, and finally to the spray head 45 for spraying. This process effectively washes and cleans the debris from the inner wall of the reaction tank body 2, making it easier for the next use.

[0040] like Figure 1 , Figure 2 and Figure 5As shown, the angle adjustment mechanism 7 includes a first hydraulic cylinder 71. The first hydraulic cylinder 71 is fixedly installed at the lower end of the support plate 6. A moving block 72 is fixedly installed at one end of the first hydraulic cylinder 71. A rack plate 73 is fixedly installed at the top back of the moving block 72. A gear 74 meshes with the surface of the rack plate 73. The lower end of the gear 74 is set at the middle of the upper end of the support plate 6 through a shaft. A second hydraulic cylinder 75 is fixedly installed at the middle of the upper end of the gear 74. A connecting rod 76 is fixedly installed at the upper end of the second hydraulic cylinder 75. A rotating rod 77 is fixedly installed on the outer surface of the connecting rod 76. A sealing plate 78 is fixedly installed at one end of the rotating rod 77. A sealing gasket is provided at the lower end of the sealing plate 78.

[0041] During operation, the first hydraulic cylinder 71 extends and retracts to move the moving block 72, which in turn moves the rack plate 73. The rack plate 73 then drives the gear 74 to rotate on the support plate 6, which in turn rotates the sealing plate 78. When the sealing plate 78 rotates to the upper end of the feed inlet 5, the second hydraulic cylinder 75 extends and retracts to move the connecting rod 76. The connecting rod 76 then moves the rotating rod 77, which in turn moves the sealing plate 78 up and down until it is in contact with the feed inlet 5 for sealing. Conversely, it moves away from the feed inlet to add material. This allows for easy adjustment of the sealing plate 78's position without the need for manual control, thus improving the device's practicality.

[0042] like Figure 1 , Figure 2 and Figure 6 As shown, the absorption mechanism 9 includes a nitrogen collection box 91. The nitrogen collection box 91 is fixedly installed on the other side of the upper end of the frame 8. A nitrogen pressure gauge 92 is fixedly installed on the front of the nitrogen collection box 91. A first delivery pipe 93 is fixedly installed on one side of the nitrogen collection box 91. One end of the first delivery pipe 93 is connected to a vacuum pump 94. One side of the vacuum pump 94 is connected to a second delivery pipe 95. One end of the second delivery pipe 95 passes through the upper end of the reaction tank body 2 and is connected to a suction port 96. The first delivery pipe 93, the second delivery pipe 95 and the suction port 96 are all made of high temperature resistant material. An exhaust pipe is provided on the other side of the nitrogen collection box 91, and the exhaust pipe is not shown in the figure.

[0043] During operation, when excessive nitrogen is generated by the internal reaction, the internal nitrogen is transported through the suction port 96 to the second delivery pipe 95 by the vacuum pump 94. The nitrogen is then transported through the second delivery pipe 95 to the first delivery pipe 93, and then through the first delivery pipe 93 to the nitrogen collection box 91 for storage. This process absorbs the excess nitrogen, reduces the internal nitrogen content, facilitates the rapid volatilization of remaining aluminum ash, improves efficiency, and saves energy.

[0044] Working principle:

[0045] First, the first hydraulic cylinder 71 extends and retracts to move the moving block 72. The moving block 72 moves the rack plate 73. The rack plate 73 drives the gear 74 to rotate on the support plate 6. The rotation of the gear 74 drives the sealing plate 78 to rotate. When the sealing plate 78 rotates to the upper end of the feed inlet 5, the second hydraulic cylinder 75 extends and retracts to move the connecting rod 76. The connecting rod 76 drives the rotating rod 77 to move. The rotating rod 77 drives the sealing plate 78 to move up and down until it fits against the feed inlet 5 for sealing. Otherwise, it adds material to facilitate the adjustment of the position of the sealing plate 78. The aluminum ash and reducing agent are heated into the reaction tank body 2. The reaction tank body 2 is automatically heated. During heating, the motor 31 is connected to an external power source to drive the rotating rod 32 to rotate. The rotating rod 32 drives the transmission rod 33 to rotate. The transmission rod 33 drives the spiral conveyor blade 34 to rotate, so as to mix the contents evenly and heat them.

[0046] Secondly, when the internal reaction produces too much nitrogen, the vacuum pump 94 causes the internal nitrogen to be transported through the suction port 96 to the second delivery pipe 95. The second delivery pipe 95 then transports the nitrogen to the first delivery pipe 93, and the first delivery pipe 93 transports the nitrogen to the nitrogen collection box 91 for storage. This absorbs the excess nitrogen inside and reduces the internal nitrogen content, making it easier for the remaining aluminum ash to volatilize quickly.

[0047] Then, after multiple uses or a single use, if the inner wall of the reaction tank body 2 becomes contaminated with debris, connect the water pipe connector 43 to the water source pipe. The high-pressure water pump 41 draws water into the first water pipe 42, the first water pipe 42 delivers the water to the second water pipe 44, and the second water pipe 44 delivers the water to the spray head 45 for spraying, thus rinsing and cleaning the debris on the inner wall of the reaction tank body 2 for the next use.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
