Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum ash calcination equipment, and in particular relates to an oxygenation mechanism for aluminum ash calcination. Background Technology

[0002] During the calcination of aluminum ash, the main function of the oxygen supply mechanism is to provide oxygen to promote the full oxidation of metallic aluminum and other combustibles in the aluminum ash, thereby improving the metal recovery rate and reducing harmful gas emissions. However, when calcining aluminum ash, it is necessary to control the temperature inside the calcination rotary furnace. The temperature inside the calcination rotary furnace is usually controlled between 800 and 1200 degrees Celsius. Excessive oxygen supply will lead to excessively high temperatures, reducing the metallic aluminum recovery rate and increasing resource waste. In addition, after the oxygen nozzles introduce oxygen into the calcination rotary furnace, the oxygen cannot be dispersed within the furnace, resulting in uneven combustion.

[0003] To address these issues, we provide an oxygenation mechanism for calcining aluminum ash. Utility Model Content

[0004] The purpose of this invention is to provide an oxygenation mechanism for calcining aluminum ash. An adjusting component is installed inside the connecting cylinder of the piping assembly. The adjusting valve of the adjusting component is slidably connected to the air inlet pipe of the piping assembly. When the temperature inside the rotary calcining furnace is too high, the air inside the thermal expansion cylinder of the adjusting component expands due to heat and pushes against the adjusting valve, reducing the amount of oxygen exiting through the vent holes on the lower side wall of the air inlet pipe, thereby reducing the oxygen supply to the calcining rotary furnace. Furthermore, a cyclone plate is installed at the lower end of the adjusting component. When oxygen is discharged from the connecting pipe head at the lower end of the connecting cylinder, it drives the cyclone plate to rotate, and the cyclone plate diffuses the oxygen into the calcining rotary furnace, making the combustion inside the calcining rotary furnace more complete.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an oxygenation mechanism for calcining aluminum ash, comprising a pipe component, an adjustment component, and a cyclone disc. The pipe component includes an inlet pipe, an outer expansion cylinder, and a connecting cylinder. The outer expansion cylinder is closed at one end and open at the other. The inlet pipe passes through the closed end of the outer expansion cylinder. A set of ventilation holes are arranged in an array on a section of the pipe wall passing through the closed end of the outer expansion cylinder. The connecting cylinder is fixedly sleeved on the open end of the outer expansion cylinder. The adjustment component is installed inside the connecting cylinder. The lower end of the connecting cylinder is connected to a connecting pipe head. The cyclone disc is installed at the lower end of the adjustment component.

[0007] A further feature of this invention is that the adjusting component includes a thermal expansion cylinder, a heat-conducting rod, and a piston. The thermal expansion cylinder is installed inside the docking cylinder, and the piston is vertically slidably sleeved inside the thermal expansion cylinder. A connecting rod is fixedly provided at the upper end of the piston, and an adjusting valve is fixedly provided at the upper end of the connecting rod. The adjusting valve is slidably sleeved inside the air inlet pipe. The upper end of the heat-conducting rod is fixedly sleeved inside the thermal expansion cylinder, and the lower end of the heat-conducting rod passes through the closed end of the lower end of the thermal expansion cylinder and extends into the docking pipe head. A cyclone disc is rotatably installed at the lower end of the heat-conducting rod.

[0008] A further feature of this invention is that a top cover is fixedly sleeved on the upper end of the thermal expansion cylinder, a connecting rod slides through the top cover, a compression spring is fixedly connected to the lower end of the top cover, and the lower end of the compression spring is fixedly connected to the upper end of the piston.

[0014] 1. This utility model installs an adjusting component inside the connecting cylinder of the pipeline component, and slides the adjusting valve of the adjusting component into the air inlet pipe of the pipeline component. When the temperature inside the rotary calcining furnace is too high, the air inside the thermal expansion cylinder of the adjusting component expands due to heat and pushes up the adjusting valve, thereby reducing the amount of oxygen coming out of the vent hole at the lower end of the air inlet pipe, thus reducing the oxygen supply to the calcining rotary furnace.

[0025] 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.

[0026] Example 1

[0027] Please see Figures 1 to 4This utility model relates to an oxygenation mechanism for aluminum ash calcination, comprising a pipe component 1, an adjusting component 2, and a cyclone disc 3. The pipe component 1 includes an inlet pipe 101, an expansion cylinder 102, and a connecting cylinder 103. By installing the adjusting component 2 inside the connecting cylinder 103 within the pipe component 1, and sliding the adjusting valve 203a-1 of the adjusting component 2 within the inlet pipe 101, when the temperature inside the rotary calcination furnace is too high, the air inside the expansion cylinder 201 of the adjusting component 2 expands due to heat and pushes against the adjusting valve 203a-1, thereby reducing the amount of oxygen output from the vent hole 101a on the lower side wall of the inlet pipe 101, thus reducing the oxygen supply to the calcination rotary furnace. By installing the cyclone disc 3 at the lower end of the adjusting component 2, when oxygen is discharged from the connecting pipe head 103a at the lower end of the connecting cylinder 103, it drives the cyclone disc 3 to rotate, and the cyclone disc 3 diffuses the oxygen into the calcination rotary furnace, making the combustion inside the calcination rotary furnace more complete.

[0028] Specifically, the outer expansion cylinder 102 is closed at one end and open at the other. The air inlet pipe 101 passes through the closed end of the outer expansion cylinder 102. A set of vent holes 101a are arranged in a section of the pipe wall through the closed end of the outer expansion cylinder 102. The docking cylinder 103 is fixedly sleeved on the open end of the outer expansion cylinder 102. The adjusting component 2 is installed inside the docking cylinder 103. The lower end of the docking cylinder 103 is connected to the docking pipe head 103a. The air cyclone 3 is installed at the lower end of the adjusting component 2.

[0029] Furthermore, the adjusting component 2 includes a thermal expansion cylinder 201, a heat-conducting rod 202, and a piston 203. The thermal expansion cylinder 201 is installed inside the docking cylinder 103. The piston 203 is vertically slidably sleeved inside the thermal expansion cylinder 201. A connecting rod 203a is fixedly provided at the upper end of the piston 203. A regulating valve 203a-1 is fixedly provided at the upper end of the connecting rod 203a. The regulating valve 203a-1 is slidably sleeved inside the air inlet pipe 101. The upper end of the heat-conducting rod 202 is fixedly sleeved inside the thermal expansion cylinder 201. The lower end of the heat-conducting rod 202 passes through the lower closed end of the thermal expansion cylinder 201 and extends towards... Inside the connecting pipe 103a, the cyclone disc 3 is rotated and installed at the lower end of the heat-conducting rod 202. The heat-conducting rod 202 transfers the high temperature inside the calcining rotary furnace to the thermal expansion cylinder 201, heating the air inside the thermal expansion cylinder 201. The air inside the thermal expansion cylinder 201 expands due to the heat and pushes the piston 203 upward, which in turn drives the regulating valve 203a-1 to move upward in the air inlet pipe 101. This continuously compresses the oxygen outlet of the vent hole 101a, reduces the oxygen output, reduces the oxygen supply to the calcining rotary furnace, and thus reduces the combustion temperature inside the calcining rotary furnace.

[0030] Furthermore, a top cover 201a is fixedly sleeved on the upper end of the thermal expansion cylinder 201, and a connecting rod 203a slides through the top cover 201a. A compression spring 201a-1 is fixedly connected to the lower end of the top cover 201a. The lower end of the compression spring 201a-1 is fixedly connected to the upper end of the piston 203. When the temperature inside the calcining rotary furnace decreases, the heat-conducting rod 202 can no longer continue to heat the air inside the thermal expansion cylinder 201, thereby cooling the air inside the thermal expansion cylinder 201, and the piston 203 resets under the compression of the compression spring 201a-1.

[0031] Furthermore, a set of heat dissipation fins 202a are fixedly arranged on the outer side of a section of the heat-conducting rod 202 inside the thermal expansion cylinder 201 to increase the heating speed of the air inside the thermal expansion cylinder 201.

[0032] Furthermore, a heat-absorbing plate 202b is threadedly connected to the lower end of the heat-conducting rod 202, and the cyclone disk 3 is rotatably installed on the upper end of the heat-absorbing plate 202b, thereby increasing the heat exchange area of ​​the heat-conducting plate 202 in the calcining rotary furnace.

[0033] The operation process in this embodiment is as follows:

[0034] Oxygen is discharged through the vent 101a on the lower side wall of the inlet pipe 101 and enters the calcining rotary furnace through the outer expansion cylinder 102 and the docking cylinder 103. When the temperature inside the calcining rotary furnace is too high, the heat-conducting rod 202 transfers the high temperature inside the calcining rotary furnace to the thermal expansion cylinder 201, heating the air inside the thermal expansion cylinder 201. The heated air expands and pushes the piston 203 upward, which in turn drives the regulating valve 203a-1 to move upward in the inlet pipe 101, thereby continuously compressing the air. The oxygen outlet of the vent 101a reduces the amount of oxygen output, thereby reducing the oxygen supply to the calcining rotary furnace and thus lowering the combustion temperature inside the calcining rotary furnace. When the temperature inside the calcining rotary furnace decreases, the heat-conducting rod 202 can no longer continue to heat the air inside the thermal expansion cylinder 201, thereby cooling the air inside the thermal expansion cylinder 201. The piston 203 is reset under the compression of the compression spring 201a-1, thereby causing the regulating valve 203a-1 to move downward and increase the amount of oxygen output from the vent 101a.

[0035] Example 2

[0036] Please see Figures 1 to 5 Based on Example 1, an installation ring 103b is also installed inside the docking cylinder 103, and a rotating cylinder shaft 302 is fixed on the cyclone plate 3. By installing the thermal expansion cylinder 201 on the installation ring 103b, a gap is maintained between the thermal expansion cylinder 201 and the docking pipe head 103a, so that the oxygen discharged from the air inlet pipe 101 can smoothly pass through the docking pipe head 103a and enter the calcining rotary furnace.

[0037] Specifically, an installation ring 103b is fixedly installed inside the docking cylinder 103. A set of connecting arms 103b-1 is fixedly arranged in a circumferential array on the inner wall of the installation ring 103b. A sleeve clamp 103b-2 is fixedly installed at one end of the connecting arm 103b-1 that is away from the installation ring 103b. The thermal expansion cylinder 201 is fixedly sleeved inside the sleeve clamp 103b-2.

[0038] Furthermore, a set of air vents 301 are arranged in a circumferential array on the surface of the cyclone disk 3, and a rotating cylinder shaft 302 is fixed in the center of the cyclone disk 3. The rotating cylinder shaft 302 is rotatably sleeved on the lower end of the heat-conducting rod 202, and a set of blades are fixed in a circumferential array on the outer side of the rotating cylinder shaft 302.

[0039] The operation process in this embodiment is as follows:

[0040] Oxygen enters the docking cylinder 103 through the vent 101a on the lower side wall of the inlet pipe 101, and enters the docking pipe head 103a through the gap between the docking cylinder 103 and the thermal expansion cylinder 201. This causes the blades on the upper rotating cylinder shaft 302 of the cyclone disk 3 to rotate, thereby diffusing oxygen in the calcining rotary furnace.
