Description

Technical Field

[0001] The invention relates to the technical field of aluminum slag processing equipment, and in particular to a stirring device for extracting ammonium sulfate from aluminum slag and aluminum ash. Background Art

[0002] Ammonium sulfate is an inorganic substance with the chemical formula (NH4)2SO4. The pure product is colorless and transparent orthorhombic crystals. The aqueous solution of ammonium sulfate is acidic, insoluble in alcohol, acetone and ammonia water, hygroscopic, and solidifies into blocks after absorbing moisture. Ammonium sulfate is mainly used as a fertilizer. It is suitable for general soil and crops. It can make branches and leaves grow vigorously, improve fruit quality and yield, and enhance the resistance of crops to disasters. It can be used as base fertilizer, topdressing and seed fertilizer. It can also be used in textiles, leather, medicine and other fields.

[0003] In the patent (application number: CN201810668460.X), an aluminum slag separation device and method are disclosed, which belongs to the field of aluminum slag recovery. Its technical scheme is: (1) collecting aluminum slag into a stirring pot, and placing the stirring pot on the platform of the aluminum slag separation device; (2) adding slag cleaning agent and / or coal powder into the stirring pot according to the temperature of the aluminum slag in the stirring pot detected by the temperature sensor, and stirring the aluminum slag, slag cleaning agent and / or coal powder in the stirring pot; (3) using an aluminum collector to collect the aluminum liquid flowing out of the aluminum liquid outlet at the bottom of the stirring pot and return it to the furnace. The device and method of the present invention improve the efficiency of aluminum slag separation, reduce the labor intensity of workers, and have the advantage of being beneficial to environmental protection.

[0004] This patent and the prior art have the following technical problems in actual use: When extracting ammonium sulfate from aluminum slag and aluminum ash, the aluminum slag is mixed with a solvent, and the mixing is accelerated by a stirring rod during mixing to make it react. During mixing, if too much aluminum slag is added, the stirring rod will contact the aluminum slag when stirring the aluminum slag. Due to the large amount of aluminum slag, the friction and resistance with the stirring rod will increase, resulting in poor mixing reaction effect. At this time, a certain amount of water needs to be added to mix it, but when water is added, the aluminum slag will dissolve faster, resulting in a fast reaction speed, which will cause the temperature of the reaction container to rise, thereby affecting the size and shape of the crystals. At the same time, if the temperature of the reaction container is high, it will be dangerous. Summary of the invention

DETAILED DESCRIPTION

[0020] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] A stirring device for extracting ammonium sulfate from aluminum slag and aluminum ash according to a preferred embodiment of the present invention will be described in detail below.

[0022] Embodiment 1, as Figure 1-Figure 7 As shown, it comprises a reaction container 1, and a stirring component 2 is arranged inside the reaction container 1; The stirring assembly 2 includes a stirring rod 201 arranged inside the reaction container 1, a torque sensor 202 is arranged on the surface of the stirring rod 201, the stirring rod 201 can rotate inside the reaction container 1, connecting pipes 203 are fixed on both sides of the stirring rod 201, the stirring rod 201 is connected with the connecting pipe 203 on one side, the connecting pipe 203 is set to be L-shaped, and the connecting pipes 203 on both sides are connected through a connecting pipe 205, an electromagnetic three-way valve 204 is fixedly installed inside the connecting pipe 203, the other end of the electromagnetic three-way valve 204 is fixedly connected to the other side of the connecting pipe 203, a rotating rod 206 that penetrates and extends to the outside of the connecting pipe 203 is rotatably installed inside the connecting pipe 205, a turbine 207 is fixedly installed on one end of the rotating rod 206, and a stirring blade 208 is fixedly installed on the other end of the rotating rod 206, a water pipe 209 is fixedly installed on the top of the connecting pipe 203 on one side, and a water storage tank 3 is arranged on one side of the reaction container 1; The stirring rod 201 is set as a hollow structure, and the connecting pipe 203 is fixedly connected to a plurality of water outlet blocks 210 on one side close to the reaction container 1. The surface of the water outlet block 210 is provided with a water outlet hole 211, and an expansion air bag 212 is fixedly installed inside the water outlet block 210. A temperature sensor 213 is fixedly installed on the inner wall of the reaction container 1; The staff adds aluminum slag or aluminum ash to the reaction container 1, and then adds the solvent, and controls the stirring rod 201 to rotate. When the stirring rod 201 rotates, it drives the connecting pipe 203 to mix the aluminum slag and the solvent. During the mixing, the torque sensor 202 continuously detects the resistance during stirring. When there is too much aluminum slag inside the reaction container 1, the resistance encountered by the stirring rod 201 during rotation will increase. When it exceeds the preset threshold of the torque sensor 202, the electromagnetic three-way valve 204 will control the valve port on one side close to the reaction container 1 to close, thereby opening the valve port on the other end, and water will be transported from the inside of the stirring rod 201 to the connecting pipe on one side. 203, water is transported from the connecting pipe 203 on one side to the connecting pipe 203 on the other side through the connecting pipe 205. At the same time, since the valve port near the turbine 207 is closed, the water will not drive the turbine 207 to rotate when it flows. When the water flows, it flows out through the water outlet 211 opened on the surface of the water outlet block 210, so that water is added during stirring to increase the mixing speed of the aluminum slag and the solvent, thereby reducing the resistance of the stirring rod 201 during rotation, which can effectively protect the stirring rod 201 from damage. The temperature sensor 213 continuously detects the temperature inside the reaction container 1. When too much water is added, the aluminum slag will react and the efficiency will decrease. The reaction speed is fast, and the temperature of the solvent inside the reaction container 1 increases due to the faster reaction speed. When the temperature inside the reaction container 1 increases, the expansion airbag 212 expands when it encounters heat, blocking the water outlet 211. At the same time, the electromagnetic three-way valve 204 will reversely open the valve port close to the turbine 207, and automatically close the valve port on the other side. The water flow will change the flow direction. When flowing, the water flow drives the turbine 207 to rotate. When the turbine 207 rotates, it drives the rotating rod 206 to rotate synchronously. When the rotating rod 206 rotates, it drives the stirring blade 208 to rotate, thereby improving the stirring efficiency and the reaction efficiency of the aluminum slag. At the same time, since the water outlet 211 is blocked by the inflatable airbag 212, water cannot flow out of the water outlet 211. When flowing into the connecting pipe 203 on the other side, it flows into the second connecting water pipe 19 through the water supply pipe 209, and then flows back into the water storage tank 3 through the second connecting water pipe 19, thereby achieving a circulating cooling effect. At the same time, due to the rotation of the stirring blade 208, the dynamic mixing of the solvent is improved, so that the solution in the high-temperature area can be quickly mixed with the surrounding cooling solution, so that the heat is evenly dispersed while accelerating the heat conduction, thereby reducing the overall temperature, so that the temperature inside the reaction container 1 is at a suitable temperature.

At the same time, during the movement, the connecting gear 12 is engaged with the meshing tooth 9, and drives the stirring rod 201 and the water pipe 209 to rotate as a whole through the fixing piece 11. At the same time, through the arrangement of the universal ball 15, the stirring rod 201 and the water pipe 209 can rotate on their own, thereby driving the connecting pipe 203 to rotate, so that the stirring rod 201 performs a circular motion along the driving disk 6, and while stirring and mixing the solution, the stirring rod 201 itself can also rotate on its own, further improving the mixing effect, thereby improving the reaction efficiency.
