The impurities on the inner wall affect the next preparation of p-diethyltoluenediamine, which improves the quality of diethyltoluenediamine. The upper sides of the four stirring plates 704 are all provided with chutes. There are connecting columns slidably connected to each other, the lower ends of the four connecting columns are welded with the adjacent sliding plates 803 respectively, and telescopic rods 804 are hinged between the four connecting columns and the four hinge seats on the first sliding sleeve 801 respectively. The sliding sleeve 801 slides down along the connecting rod 710. The first sliding sleeve 801 drives the lower ends of the four telescopic rods 804 to move away from each other.

The outer sides of the four telescopic rods 804 are all sleeved with first springs 805, and the two ends of the four first springs 805 are respectively fixed to the adjacent telescopic rods 804. When the outer end of the sliding plate 803 contacts the turning point of the inner wall of the mixing chamber 2, under the action of the elastic force of the first spring 805, the telescopic rod 804 drives the sliding plate 803 to slide to the outside along the stirring plate 704, so that the four The sliding plates 803 are always in contact with the inner wall of the mixing chamber 2 .

When using the device, the operator climbs to the upper part of the mixing chamber 2 using tools such as escalators, and then the operator rotates the rotating wheel on one of the rotating shafts 616 counterclockwise, and the rotating shaft 616 drives the first gear 617 to rotate counterclockwise to make the two The rack 619 moves away from other parts on its upper part, the torsion spring 618 is tightened, and the two adjacent racks 619 drive the tooth blocks 620 thereon to move away from each other through the fixing plate respectively. The tooth blocks 620 lose their engagement with the adjacent tooth plates 614 respectively, and then the operator drives the sliding shell 615 to drive the circular plate on it to slide up along the sliding rail 6141. When the designated position is reached, the operator releases the rotating shaft 616. Rotating the wheel, then under the action of the torsion spring 618, the two racks 619 drive the tooth blocks 620 on them to reset, and the two tooth blocks 620 re-engage with the adjacent tooth plates 614, so that the sliding shell 615 It is re-fixed, and then the operator repeats the above operation to re-fix the position of other sliding shells 615. The operator accurately adjusts the position of the sliding shell 615 according to the scale line on the sliding rail 6141, and adjusts the distance that the piston plate 610 moves upward each time. Then the operator connects the feed ports at the upper ends of the two material tanks 603 with the supply tanks for the two liquid raw materials, respectively, and pumps the two liquid raw materials into the two material tanks 603, so that the two material tanks 603 are always filled with liquid raw materials, and then the operator presses the start button of the control panel 5, the control panel 5 first starts the first electric push rod 613, when the push rod of the first electric push rod 613 is in the state of not extending, all the first solenoid valves 606 In the open state, when the push rod of the first electric push rod 613 drives the connecting plate 612 to move upward, the control panel 5 opens all the second solenoid valves 609 and closes all the first solenoid valves 606, and the first electric push rod The push rod of 613 drives the connecting plate 612 to move upward, and the connecting plate 612 slides upward along all the first connecting rods 611. When the connecting plate 612 squeezes the circular plate at the bottom of the sliding shell 615, the connecting plate 612 drives the first connecting rod 612. The connecting rod 611 and the piston plate 610 move upward along the inner wall of the adjacent cylindrical shell 605, the piston plate 610 pushes out the liquid raw material in the cylindrical shell 605 along the arc-shaped pipe 607, and the pushed liquid raw material enters the second water distribution pipe 608, The sliding shell 615 on the upper side makes the piston plate 610 move up a small distance, so that the liquid material in the cylindrical shell 605 is pushed in less, and the volume of the liquid material pushed by the cylindrical shells 605 on both sides is different each time. Then the two liquid raw materials flow into the mixing chamber 2, the push rod of the first electric push rod 613 drives the connecting plate 612 to move down, and the connecting plate 612 drives all the piston plates 610 and the first connection The rod 611 is reset. During the reset process of the piston plate 610 and the first connecting rod 611, the first solenoid valve 606 is opened and the second solenoid valve 609 is closed, and the two liquid raw materials enter the cylindrical shell 605 through the two first water distribution pipes 604. Pass the sliding shell on both sides 6 15. The height is adjusted so that the liquid raw material pushed into the second water distribution pipe 608 by each cylindrical shell 605 is a fixed value each time. After adjusting the sliding shells 615 on both sides according to a specific ratio, the two liquid raw materials enter the mixing chamber. The amount in 2 is a fixed value, which avoids the influence of the bottom pressure of the material box 603 on the feeding, and at the same time avoids the different feeding amounts of the two liquid materials, resulting in inaccurate proportions of the two liquid materials, resulting in diethyltoluene diethylbenzene. The production quality of amine products declined.

At the same time, the control panel 5 starts the first servo motor 703, the output shaft of the first servo motor 703 drives the second gear 7031 to rotate clockwise, and the second gear 7031 drives the rotating shell 701 and other components on the upper part counterclockwise through the gear ring 702 Rotating, the rotating shell 701 drives the reciprocating screw 706 and the connecting block 707 to rotate. Since the connecting rod 710 and the reciprocating screw 706 are connected as a one-way bushing, the counterclockwise rotation of the rotating shell 701 will not drive the connecting rod 710 to rotate. The rotating shell 701 drives the four stirring plates 704 to rotate counterclockwise to agitate the two liquid materials entering the mixing chamber 2 . During the counterclockwise stirring process, the two liquid materials continuously impact the corners in the mixing chamber 2 , make the two liquid materials collide and mix, and use the stirring plate 704 and the mixing chamber 2 to mix the two liquids fully and evenly, reducing the stirring time of the two liquid materials and improving the production efficiency of diethyltoluenediamine, After one end of time, the control panel 5 resets and closes the first electric push rod 613, so that the two liquid materials stop entering the mixing chamber 2, and after a period of stirring, the preparation of diethyltoluenediamine is completed, and the control panel 5 Turn off the first servo motor 703, then the operator connects the diethyltoluenediamine collection tank and the discharge pipe of the mixing chamber 2 through a conduit, and then the operator opens the valve on the discharge pipe of the mixing chamber 2, and the diethyltoluenediamine It enters the diethyltoluenediamine collection box through the discharge pipe, and at the same time, the air intake valve 301 enters the air, so that the diethyltoluenediamine is quickly discharged from the mixing chamber 2, reducing the discharge time. After all the diamine is discharged, the operator closes the valve on the discharge pipe and disconnects the pipe on the collection tank of diethyltoluene diamine from the discharge pipe.

Then the operator pumps the cleaning liquid into the mixing chamber 2 through the water inlet pipe 4, and uses the nozzle at the right end of the water inlet pipe 4 to spray the cleaning liquid evenly on the inner wall of the mixing chamber 2 and the four stirring plates 704, and then the operator passes through the control panel 5.

When the four sliding plates 803 contact the inner wall of the mixing chamber 2, The four telescopic rods 804 are compressed inward, and at the same time, the first spring 805 is compressed. Then the operator starts the first servo motor 703 again through the control panel 5, so that the rotating shell 701 drives the four stirring plates 704 to rotate counterclockwise. The plate 704 drives the sliding plate 803 on it to rotate counterclockwise along the inner wall of the mixing chamber 2. When the outer end of the sliding plate 803 contacts the turning point of the inner wall of the mixing chamber 2, the telescopic rod 804 is driven by the elastic force of the first spring 805. As the sliding plate 803 slides to the outside along the stirring plate 704, the four sliding plates 803 are always in contact with the inner wall of the mixing chamber 2. When the sliding plate 803 passes through the turn of the mixing chamber 2, the sliding plate 803 is squeezed and moves along the stirring plate 704. At the same time, the telescopic rod 804 is contracted, the first spring 805 is compressed, and the four sliding plates 803 are used to clean the residual diethyltoluenediamine and impurities in the mixing chamber 2, so as to avoid the impurities on the inner wall of the mixing chamber 2 from affecting the next time.

After cleaning the inner wall of the mixing chamber 2, the control panel 5 automatically turns off the first servo motor 703, the control panel 5 resets and closes the second electric push rod 802, and the four sliding plates 803 are reset. During the process, the four agitating plates 704 clean the impurities adhered to the outer sides of the four sliding plates 803 respectively, and then the control panel 5 starts the second servo motor 709, and the output shaft of the second servo motor 709 drives the connecting rod 710 to rotate clockwise. , the connecting rod 710 drives the reciprocating screw 706 to rotate clockwise through the one-way bushing, and the reciprocating screw 706 drives the connecting block 707 and the four cleaning plates 708 to move down along the long through holes of the rotating shell 701 through the thread, and the four A cleaning plate 708 scrapes and cleans the residual diethyltoluenediamine and impurities on the outer surfaces of the four stirring plates 704, so as to reduce the adhesion of diethyltoluenediamine and impurities on the four stirring plates 704, so as to avoid the need for the next time. The preparation of diethyltoluenediamine has an impact. When the connecting block 707 moves to the lowermost side of the reciprocating screw 706, the reciprocating screw 706 drives the connecting block 707 to move up and reset. After the connecting block 707 is reset, the control panel 5 is then closed. The second servo motor 709, then the operator opens the valve on the discharge pipe again, so that the cleaning liquid is discharged from the discharge pipe, and the cleaning liquid discharges the residual diethyltoluenediamine and impurities in the mixing chamber 2, and then the operator closes The valve on the discharge pipe is convenient for the next use of the device.
