Description

Technical Field

[0001] This utility model relates to the field of decomposition tank technology, and in particular to an alumina decomposition tank. Background Technology

[0002] Alumina, also known as bauxite, is a white powder that is refractory and insoluble in water. It has a high hardness. Alumina decomposition has a wide range of applications in bauxite processing, refractory material manufacturing and other fields. For example, aluminum hydroxide can be precipitated from sodium aluminate solution through a fractional decomposition method to produce high-purity alumina.

[0003] For a long time, the stirring power equipment of the decomposition tank in the alumina decomposition process has been relatively expensive. It not only consumes a lot of electricity, but also has high maintenance and repair costs. Chinese Patent Publication No. CN207294199U discloses an alumina decomposition tank that uses compressed air and electricity as stirring power sources, avoiding the drawbacks of using only electricity, reducing the load on the power equipment, and lowering the operating cost. However, the above device does not have a cooling component on the decomposition tank. If the temperature is too high, the decomposition rate of the solution will be significantly reduced, which will also affect the decomposition efficiency of alumina. Therefore, we propose an alumina decomposition tank. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an alumina decomposition tank. The structure of the decomposition tank body surrounded by an annular pipe ensures that the decomposition tank body is evenly exposed to cold water during cooling. This avoids large local temperature differences that could affect the uneven heating and cooling of the alumina inside the decomposition tank body, thus hindering the decomposition process. After cooling, the cold water will warm up and then flow back to the inside of the water tank from the upper end of the annular pipe. Therefore, the water used for cooling can be recycled, greatly saving water resources and making the device more energy-efficient.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An alumina decomposition tank includes a main body, a cleaning mechanism installed inside the main body, and a cooling mechanism installed outside the main body.

[0007] The cooling mechanism includes a water tank, a circulating cooling pump fixedly installed at the lower inner end of the water tank, and an annular pipe fixedly installed at the outer end of the circulating cooling pump. A connector is fixedly installed at the upper end of the water tank and fixedly connected to the annular pipe. A water inlet is fixedly installed on the side of the upper end of the water tank. The annular pipe can form a surrounding structure to encircle the component. When in use, the water inside the water tank is cooled to a low temperature by the circulating cooling pump and flows through the inside of the annular pipe, so that the component surrounded by the annular pipe is effectively cooled. After being cooled, the cold water will warm up and then flow back to the inside of the water tank from the upper end of the annular pipe. Therefore, the water used for cooling can be recycled.

[0008] Furthermore, the main body mechanism includes a decomposition tank body, an insulation pad fixedly installed at the lower end of the decomposition tank body, a sandwich layer fixedly installed inside the decomposition tank body, a motor fixedly installed at the upper end of the decomposition tank body, a transmission rod fixedly installed at the lower end of the motor, a rotating shaft fixedly installed at the lower end of the transmission rod, a stirring frame fixedly installed at the lower end of the rotating shaft, a stirring roller fixedly installed at the inner end of the stirring frame, and a material suction pipe fixedly installed on the side inside the decomposition tank body. The insulation pad ensures that the lower end of the device will not directly contact the ground or operating table when placed, effectively preventing temperature drop or rise caused by conduction from the lower end of the decomposition tank body.

[0009] Furthermore, the cleaning mechanism includes a retaining ring, an extension rod fixedly installed at the outer end of the retaining ring, a cleaning ring fixedly installed at the outer end of the extension rod, a cleaning brush fixedly installed at the inner end of the cleaning ring, and an electric lifting rod fixedly installed at the middle of the upper end of the extension rod. By setting the electric lifting rod, the cleaning ring and the retaining ring can move up and down at the outer end of the mixing frame.

[0010] Furthermore, the water tank is fixedly installed on the outside of the decomposition tank body, and the annular pipe is fixedly installed inside the interlayer. The upper end of the annular pipe is fixedly connected to the water tank through a connector. The interlayer allows the annular pipe to completely surround the decomposition tank body, so that the decomposition tank body cools down evenly during cooling, avoiding large local temperature differences that could affect the uneven heating and cooling of the alumina inside the decomposition tank body and thus affect the decomposition.

[0011] Furthermore, the rotating shafts are symmetrically distributed in the middle of the upper and lower ends of the stirring frame, the stirring rollers are arranged in a ring array in the inner end of the stirring frame, and the drive end of the motor and the drive rod are fixedly connected.

[0012] Furthermore, the retaining ring is movably installed in the middle of the mixing frame, and the extension rod is movably connected to the mixing frame via an electric lifting rod.

[0013] Furthermore, the extension rods are arranged in a ring at the outer end of the retaining ring, and the number of the extension rods corresponds to the number of the stirring rollers.

[0014] Furthermore, the cleaning brush has a ring structure, and the upper end of the ring tube extends into the interior of the water tank.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. The structure of the decomposition tank body surrounded by the annular pipe ensures that the decomposition tank body is evenly exposed to cold water during cooling. This avoids large local temperature differences that could affect the decomposition of alumina inside the decomposition tank body due to uneven heating and cooling. After cooling, the cold water will warm up and then flow back to the inside of the water tank from the top of the annular pipe. Therefore, the water used for cooling can be recycled, which greatly saves water resources and makes the device more energy-efficient.

[0017] 2. The cleaning ring at the outer end of the extension rod is located on the outside of the stirring roller and fits against it. When the stirring roller stirs the alumina and produces adhesive, the cleaning ring rubs against the stirring roller under the drive of the electric lifting rod, which can remove the adhesive on the outer end of the stirring roller.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] Reference Figure 1-5As shown, an alumina decomposition tank is provided in a preferred embodiment of the present invention, including a main body 1, a cleaning mechanism 2 installed inside the main body 1, and a cooling mechanism 3 installed outside the main body 1.

[0027] The cooling mechanism 3 includes a water tank 301. A circulating cooling pump 302 is fixedly installed at the lower inner end of the water tank 301. An annular pipe 303 is fixedly installed at the outer end of the circulating cooling pump 302. A connector 304 is fixedly installed at the upper end of the water tank 301 and is fixedly connected to the annular pipe 303. A water inlet 305 is fixedly installed on the side of the upper end of the water tank 301. The annular pipe 303 can surround the components in a closed structure. When in use, the water inside the water tank 301 is cooled to a low temperature by the circulating cooling pump 302 and flows through the inside of the annular pipe 303, so that the components surrounded by the annular pipe 303 are effectively cooled. After being cooled, the cold water will warm up and then flow back to the inside of the water tank 301 from the upper end of the annular pipe 303. Therefore, the water used for cooling can be recycled.

[0028] The main body 1 includes a decomposition tank body 101. A heat insulation pad 102 is fixedly installed at the lower end of the decomposition tank body 101. A sandwich layer 103 is fixedly installed inside the decomposition tank body 101. A motor 104 is fixedly installed at the upper end of the decomposition tank body 101. A transmission rod 105 is fixedly installed at the lower end of the motor 104. A rotating shaft 106 is fixedly installed at the lower end of the transmission rod 105. A stirring frame 107 is fixedly installed at the lower end of the rotating shaft 106. A stirring roller 108 is fixedly installed at the inner end of the stirring frame 107. A material suction pipe 109 is fixedly installed on the side inside the decomposition tank body 101. The heat insulation pad 102 ensures that the lower end of the device will not directly contact the ground or operating table when placed, effectively preventing cooling or heating caused by conduction from the lower end of the decomposition tank body 101.

[0029] The cleaning mechanism 2 includes a retaining ring 201, an extension rod 202 fixedly installed at the outer end of the retaining ring 201, a cleaning ring 203 fixedly installed at the outer end of the extension rod 202, a cleaning brush 204 fixedly installed at the inner end of the cleaning ring 203, and an electric lifting rod 205 fixedly installed at the middle of the upper end of the extension rod 202. By setting the electric lifting rod 205, the cleaning ring 203 and the retaining ring 201 can move up and down at the outer end of the mixing rack 107.

[0030] The water tank 301 is fixedly installed on the outside of the decomposition tank body 101, and the annular pipe 303 is fixedly installed inside the interlayer 103. The upper end of the annular pipe 303 is fixedly connected to the water tank 301 through the connector 304. The interlayer 103 makes the annular pipe 303 completely surround the decomposition tank body 101 so that the decomposition tank body 101 cools down evenly during cooling, and avoids large local temperature differences affecting the uneven heating and cooling of the alumina inside the decomposition tank body 101, which would affect the decomposition.

[0031] The rotating shafts 106 are symmetrically distributed in the middle of the upper and lower ends of the stirring frame 107, and the stirring rollers 108 are arranged in a ring array in the inner end of the stirring frame 107. The transmission end of the motor 104 is fixedly connected to the transmission rod 105. During operation, the motor 104 drives the stirring frame 107 to rotate through the transmission rod 105, so that the alumina inside the decomposition tank body 101 is fully decomposed.

[0032] The retaining ring 201 is movably installed in the middle of the mixing frame 107. The extension rod 202 is movably connected to the mixing frame 107 via the electric lifting rod 205. The retaining ring 201 is located on the outer side of the middle of the mixing frame 107, so that it does not rub against the mixing frame 107 when the electric lifting rod 205 moves up and down.

[0033] The extension rods 202 are arranged in a ring at the outer end of the retaining ring 201. The number of extension rods 202 corresponds to the number of stirring rollers 108. The cleaning rings 203 set at the outer ends of the extension rods 202 are located on the outside of the stirring rollers 108 and are attached to them. When the stirring rollers 108 stir alumina and produce adhesive, the cleaning rings 203 are driven by the electric lifting rods 205 to rub against the stirring rollers 108, thereby removing the adhesive on the outer end of the stirring rollers 108.

[0034] The cleaning brush 204 has a ring structure. The upper end of the ring tube 303 extends into the interior of the water tank 301. The cleaning brush 204 is wrapped around the outer end of the stirring roller 108 and is made of high-temperature resistant soft nylon, so it will not cause damage when cleaning the stirring roller 108.

[0035] Specific implementation process: During assembly, the annular pipe 303 is first fixedly installed in the interlayer 103 inside the decomposition tank body 101. The annular pipe 303 surrounds the decomposition tank body 101. The lower end of the annular pipe 303 is connected to the water tank 301 through the circulating cooling pump 302, and the upper end extends from the upper end of the water tank 301 into the interior of the water tank 301 and is fixed through the connector 304. When the temperature of the alumina inside the decomposition tank body 101 is high during decomposition, the circulating cooling pump 302 is driven to make water flow. The cooling process involves the water flowing through the annular pipe 303 along the outer end of the decomposition tank body 101. The structure of the annular pipe 303 surrounding the decomposition tank body 101 ensures that the decomposition tank body 101 is in uniform contact with the cold water during cooling. This avoids large local temperature differences that could affect the decomposition of alumina inside the decomposition tank body 101 due to uneven heating and cooling. After cooling, the cold water will warm up and then flow back from the upper end of the annular pipe 303 to the interior of the water tank 301. Therefore, the water used for cooling can be recycled, which greatly saves water resources and makes the device more energy-efficient.
