[0003] The patent document with publication number CN205146191U discloses an aluminum alcohol salt synthesis device, which comprises a kettle body, a reflux condenser is connected and arranged at the upper part of the kettle body, a heating coil and a support plate are arranged at the bottom of the kettle body, the support plate is arranged in the kettle body and above the heating coil, a plurality of through holes are arranged on the support plate, a jacket for heating or cooling is further arranged on the kettle wall of the kettle body; an alcohol evaporation recovery outlet and a feeding port are further arranged at the upper part of the kettle body, and a discharging port is arranged at the bottom; a sight glass and a flow regulating valve are arranged on the pipeline connected with the kettle body of the reflux condenser, the lower end of the reflux condenser is further communicated with the kettle body through a bypass pipe and a bypass valve arranged thereon; the upper part of the reflux condenser is communicated with a hydrocyclone, and an exhaust port, a vent valve and a liquid discharge port are arranged on the hydrocyclone. Alcohol and initiator solution are added into the kettle body, and then aluminum is added into the kettle body for synthesis reaction.

[0004] In the synthesis of aluminum alcohol, aluminum powder or aluminum ingot is used to react with organic alcohol, and in the use of aluminum ingot, the size of the aluminum ingot is too large to significantly reduce the contact area with the organic alcohol, resulting in the decrease of the synthesis efficiency of aluminum alcohol. Therefore, the aluminum ingot is cut into several aluminum blocks, and then the aluminum blocks are put into the organic alcohol for reaction.

[0005] The above-mentioned prior art has the following problems in the synthesis of aluminum alcohol salt. The aluminum blocks are exposed to the air, and a dense aluminum oxide film is formed on the surface of the aluminum blocks. If the aluminum blocks are not pretreated with an activating agent, the reaction will start slowly, and then the local intense heat release in the early stage of the reaction will cause the uneven generation of aluminum alcohol viscous material on the surface of the aluminum blocks, which will be attached to the aluminum blocks or the kettle wall to form caking. In addition, if the aluminum blocks are stacked at the bottom of the reaction kettle, the conventional stirring structure cannot effectively disperse the aluminum blocks, the gaps between the aluminum blocks are filled with viscous aluminum alcohol generated by the reaction, and hard blocks are formed after solidification, which gradually solidify the caking.

[0055] A controller is arranged on the kettle body 1, control ends of the controller are electrically connected with switches of the power element 1 31 and the power element 2 32, an inductive element is arranged at the upper side wall of the opening 211, the inductive element is arranged as an infrared sensor, and the inductive element is electrically connected with a signal receiving end of the controller.

[0056] After the aluminum blocks are consumed, the bending part 51 moves to the upper side wall of the opening 211, the inductive element sends a signal to the controller when detecting that the bending part 51 moves to the position, and the controller controls the power element 1 31 and the power element 2 32 to start, so that the annular frame 21 is moved from the reaction liquid to perform feeding and realize automatic continuous synthesis production.

[0057] Referring to Figure 2 , Figure 6 A connecting frame 412 is rotatably arranged in the standby frame 41, the connecting frame 412 is connected with the intermediate rod 33, a plurality of shift rods 413 are arranged on the connecting frame 412, and the plurality of shift rods 413 are arranged in up-down arrangement on the connecting frame 412. When feeding, the power element 1 31 drives the intermediate rod 33 to rotate, and the intermediate rod 33 drives the connecting frame 412 and the shift rods 413 to rotate, so that the aluminum blocks in the standby frame 41 are pushed to the outlet 411 for discharge.

[0058] Referring to Figure 2 , Figure 6An auxiliary frame 9 is arranged below the preparation frame 41, and is used to place an activator solution for pre-treating the aluminum blocks. An intermediate hole 414 is formed in the inner side of the preparation frame 41, and is located at the bottom of the preparation frame 41 and communicates with the auxiliary frame 9. A sliding sleeve 91 is slidably arranged in the auxiliary frame 9, and is sleeved on the outer side of the intermediate rod 33. The lower end of the sliding sleeve 91 extends below the auxiliary frame 9, and the connecting frame 8 is located below the sliding sleeve 91. A spring 92 is arranged in the sliding sleeve 91, and is arranged as a spring. The spring 92 is connected with the intermediate rod 33 to drive the sliding sleeve 91 to move downward. An extrusion block 93 is arranged at the upper end of the sliding sleeve 91, and the cross section of the extrusion block 93 is larger than the area of the sliding sleeve 91.

[0059] During the feeding, the connecting frame 8 abuts against the lower end of the sliding sleeve 91, and the extrusion block 93 is located outside the activator solution, and the activator solution is located in the auxiliary frame 9. After the feeding is completed, the annular frame 21 moves downward, and the spring 92 drives the sliding sleeve 91 to move downward. The bending part 51 is separated from the blocking ring 6, and the baffle 42 moves downward to close the outlet 411. Then, the extrusion block 93 moves into the activator solution. As the extrusion block 93 gradually enters the activator solution, the liquid level of the activator increases, and then enters the bottom of the preparation frame 41 through the intermediate hole 414, so that the activator contacts the aluminum blocks at the bottom of the preparation frame 41, and pre-treats the oxide layer on the surface of the aluminum blocks, so as to facilitate the subsequent synthesis reaction.

[0060] In the embodiment, the activator is dilute nitric acid. The activator dissolves the aluminum oxide on the surface of the aluminum blocks through slight corrosion, exposes the active metal section, and provides a reaction site for the synthesis of aluminum alcohol. The initial reaction is slow due to the oxide layer, which causes local intense heat release and reduces the formation of clumps.

[0061] Similarly, when the annular frame 21 moves out, the connecting frame 8 abuts against the sliding sleeve 91 first, and drives the extrusion block 93 to move to the outside of the activator. After the activator in the preparation frame 41 flows back into the auxiliary frame 9, the bending part 51 cooperates with the blocking ring 6 to open the outlet 411.

[0062] Reference Figure 6 A support plate 94 is arranged in the preparation frame 41, and a plurality of flow holes 95 are formed in the support plate 94. The outlet 411 and the intermediate hole 414 are respectively arranged on the inner and outer sides of the preparation frame 41, and the outlet 411 is arranged above the intermediate hole 414. The support plate 94 is arranged between the outlet 411 and the intermediate hole 414. The activator enters above the support plate 94 through the intermediate hole 414 and the flow holes 95 in sequence, and contacts the aluminum blocks to treat the aluminum blocks. The intermediate hole 414 is arranged below the outlet 411, so that when the outlet 411 is opened, the activator in the preparation frame 41 can flow back into the auxiliary frame 9. At the same time, the residual activator in the preparation frame 41 is prevented from entering the annular frame 21.

[0063] The implementation principle of the present application is that the aluminum blocks are arranged up and down in the annular frame 21, the annular frame 21 can move up and down to drive the aluminum blocks into the reaction liquid, at the same time, the annular frame 21 rotates in the reaction liquid, which improves the contact area of the aluminum blocks with the reaction liquid, in addition, when the temperature is too high during the reaction, the annular frame 21 can be moved upward to move part or all of the aluminum blocks to the outside of the reaction liquid to control the reaction temperature, and after the reaction of the aluminum blocks is completed, the annular frame 21 is moved upward to the standby frame 41, the bending part 51 cooperates with the blocking ring 6 to open the outlet 411 for feeding. The temperature of the reaction is controlled by moving the annular frame 21 up and down.

[0064] In addition, the activator is introduced into the standby frame 41 through the extrusion block 93 and contacts the aluminum blocks at the bottom of the standby frame 41 to pretreat the oxide layer on the surface of the aluminum blocks, provide reaction sites for the synthesis of aluminum alcohol, reduce the phenomenon of local intense heat release due to slow reaction in the initial stage of the reaction, so as to control the temperature of the subsequent reaction. The oxide layer on the surface of the aluminum blocks is pretreated by moving the annular frame 21 up and down and the activator, which reduces the phenomenon of material agglomeration of the aluminum blocks due to local high temperature during the reaction, so as to improve the synthesis efficiency of aluminum alcohol.
