Through the arrangement, on one hand, the liquid level below the lowest stirring rod 31 is stirred, and on the other hand, the downward pressure provided by the turnover plate 25 can enable the mixture in the reaction kettle cylinder 1 to generate a linear flowing trend of a magnetic field, so that the mixing efficiency of the fatty acid methyl ester ethoxylate and the ionized water is further improved, and meanwhile, the phenomenon that the mixture flows back to a receiving device containing the ionized water is avoided due to the existence of the downward pressure.

When the feeding speed of the ionized water is increased, the ionized water entering the reaction kettle cylinder 1 is positioned at the middle upper part of the fatty acid methyl ester ethoxylate, at the moment, the mixture is stirred by only the stirring rod 31, so that the materials are difficult to mix sufficiently (the situation that the concentration of the ionized water at the upper layer and the lower layer of the mixture is different easily occurs), or when the mixture is in a completely mixed state, the stirring time is long, the processing speed is influenced, when the connecting frame 12 moves downwards, the follower 18 is driven to move downwards by the connecting rod 17, so that the lifting sleeve 19 moves downwards, the vertical rod 23 is driven to move downwards, and one end of the vertical rod 23 far away from the lifting sleeve 19 is rotatably provided with the sliding block 24, and the sliding block 24 slides in the sliding groove 26 arranged on the turnover plate 25, so that when the vertical rod 23 moves downwards, the sliding block 24 is driven to slide in the sliding groove 26, and the turnover plate 25 is driven to turn over, so that the included angle between the turnover plate 25 and the inner bottom wall of the reaction kettle cylinder 1 is increased, so that the downward pressure generated when the turnover plate 25 rotates is driven to move downwards, and the ionized water enters the reaction kettle cylinder 1 is increased.
Through the above-mentioned setting, realized the linkage between the unloading volume of ionized water and the downforce that turns over board 25 produced to make when the unloading volume of ionized water increases, the downforce that turns over board 25 produced increases, thereby when ionized water enters into the material in the reation kettle barrel 1 more, ionized water evenly distributed in fatty acid methyl ester ethoxylate that can be more quick, make the two mixing efficiency higher, avoid between fatty acid methyl ester ethoxylate upper strata and lower floor, the concentration of ionized water exists the difference.
Furthermore, due to the existence of the limiting block 21 and the limiting groove 22, the lifting sleeve 19 can always rotate along with the rotating shaft 4 after lifting, and the annular embedded groove 20 is matched with the follower 18, so that after the height of the follower 18 is determined, the lifting sleeve 19 cannot change in height even if rotating, and the stability is improved.
In summary, when the ion water is slowly added into the reaction kettle cylinder 1, the first driving device 3 is started at the same time, the output shaft of the first driving device 3 drives the rotation shaft 4 to rotate, and in the invention, as shown in fig. 3, three groups of stirring rods 31 with different heights are provided, the height of the fatty acid methyl ester ethoxylate can be slightly lower than the height of the stirring rod 31 positioned at the bottommost part when the fatty acid methyl ester ethoxylate is added into the reaction kettle cylinder 1, at the moment, when the rotation shaft 4 rotates, due to the action of gravity, the embedded upright post 30 on the embedded ring 33 is separated from the embedded hole 29 on the side wall of the concave groove 28, at the moment, the embedded ring 33 is in a state of being separated from the rotation shaft 4, namely, the rotation shaft of the rotation shaft 4 can not drive the embedded ring 33 and the stirring rod 31 to rotate, and along with the addition of the ion water, the height of the mixture in the reaction kettle cylinder 1 is increased, at this time, the height of the liquid surface of the mixture is larger than the height of the stirring rod 31 at the bottommost part, so that the hollow floating ball 32 generates buoyancy and drives the stirring rod 31 and the sleeve ring 33 to move upwards, and when the embedded upright post 30 is inserted into the embedded hole 29, the sleeve ring 33 rotates along with the rotating shaft 4, so that the stirring of the mixture is realized through the stirring rod 31, in this state, the two sleeve rings 33 at the upper part are in a free movement state, the output load of the first driving device 3 is smaller when the liquid surface in the reaction kettle cylinder 1 is lower, and the two sleeve rings 33 at the upper part rotate sequentially along with the rising of the liquid surface in the reaction kettle cylinder 1, so that the mixture at each height of the reaction kettle cylinder 1 is effectively stirred, and the mixing rate of the mixture is improved.
In the initial state, the turnup plate 25 is in an inclined state, specifically, a certain angle exists between the turnup plate 25 and the inner bottom wall of the reaction kettle barrel 1, at this time, when ionized water is added into the reaction kettle barrel 1, and the rotating shaft 4 rotates, the turnup plate 25 can stir the liquid surface below the lowest stirring rod 31 on one hand, and can enable the mixture in the reaction kettle barrel 1 to generate a linear flowing trend of a magnetic field, so that when ionized water enters the reaction kettle barrel 1, the mixture can be quickly mixed with fatty acid methyl ester ethoxylate, and meanwhile, when the turnup plate 25 rotates along with the rotating shaft 4, the turnup plate 25 generates a downward pressure, so that the mixture in the reaction kettle barrel 1 is prevented from being higher on the side wall of the reaction kettle barrel 1 due to centrifugal force generated by rotation, and the mixture is prevented from flowing back into a receiving device containing ionized water.
When the rotation shaft 4 rotates, the rotation shaft 4 drives the transmission rod 6 to rotate through the bevel gear set 5, the transmission rod 6 drives the plugging turntable 8 to rotate through the belt 7, the plugging turntable 8 is arranged between two sections of conduction pipes, so that in the process of rotating the plugging turntable 8, when the conduction holes 9 on the plugging turntable 8 are overlapped with the inner diameter of the conduction pipes, the feeding hole 10 is conducted, the ionized water in the receiving device can enter the reaction kettle barrel 1, the receiving device has a certain extrusion force on the ionized water filled in the receiving device, and therefore when the feeding hole 10 is conducted, the ionized water can enter the reaction kettle barrel 1, and a plurality of conduction holes 9 are circumferentially arranged on the plugging turntable 8, so that when the plugging turntable 8 rotates, the ionized water in the receiving device continuously and discontinuously enters the reaction kettle barrel 1, and is mixed with fatty acid methyl ester ethoxylate in the reaction kettle barrel 1.
When the feeding speed of the ionized water needs to be regulated, the second driving device 16 is controlled to work, the output shaft of the second driving device 16 drives the screw rod 15 to rotate, the threaded sleeve 14 arranged on the screw rod 15 moves along the axial direction of the screw rod 15, specifically, when the threaded sleeve 14 moves downwards along the axial direction of the screw rod 15, the threaded sleeve 14 drives the connecting frame 12 to move downwards, so that the feeding port 10 moves downwards along the length direction of the vertical groove, wherein the sealing sliding piece 11 can always cover the vertical groove, the situation that the reaction kettle cylinder 1 is communicated with the outside when the position of the feeding port 10 is regulated, impurities are introduced, and when the plugging turntable 8 rotates after the feeding port 10 moves downwards, the area when the conducting hole 9 is overlapped with the feeding port 10 is increased, so that the feeding speed of the ionized water is increased.
When the feeding speed of the ionized water is increased, the ionized water entering the reaction kettle cylinder 1 is positioned at the middle upper part of the fatty acid methyl ester ethoxylate, at the moment, the mixture is stirred by only the stirring rod 31, so that the materials are difficult to mix sufficiently (the situation that the concentration of the ionized water at the upper layer and the lower layer of the mixture is different easily occurs), or when the mixture is in a completely mixed state, the stirring time is long, the processing speed is influenced, when the connecting frame 12 moves downwards, the follower 18 is driven to move downwards by the connecting rod 17, so that the lifting sleeve 19 moves downwards, the vertical rod 23 is driven to move downwards, and one end of the vertical rod 23 far away from the lifting sleeve 19 is rotatably provided with the sliding block 24, and the sliding block 24 slides in the sliding groove 26 arranged on the turnover plate 25, so that when the vertical rod 23 moves downwards, the sliding block 24 is driven to slide in the sliding groove 26, and the turnover plate 25 is driven to turn over, so that the included angle between the turnover plate 25 and the inner bottom wall of the reaction kettle cylinder 1 is increased, so that the downward pressure generated when the turnover plate 25 rotates is driven to move downwards, and the ionized water enters the reaction kettle cylinder 1 is increased.
