Description

Technical Field

[0001] The present invention relates to the technical field of reaction devices, and particularly to a cyanate synthesis reaction device and method facilitating the preparation of lye. Background Art

[0002] Cyanates are a class of organic compounds containing isocyanate groups (–N=C=O). Cyanates are important chemical intermediates and are widely used in the synthesis of polymeric materials, pharmaceutical chemicals, pesticides, dyes, etc. The most common cyanates are isocyanates, which are commonly used in the production of polyurethanes. When synthesizing cyanates, lye needs to be added. By precisely adjusting the concentration and addition rate of the lye, the main reaction can be selectively promoted (in the synthesis process of cyanates, cyanides react with alcohols to form cyanates. Lye can increase the alkalinity of the reaction system, enhance the nucleophilicity of cyanides, and make them more likely to react with alcohols); the side reactions can be inhibited (by adjusting the concentration and addition rate of the lye, the reaction rate can be controlled to avoid the reaction being too violent, resulting in the generation of by-products or instability during the reaction), thereby improving the yield and purity of the product.

[0003] In the existing cyanate synthesis devices, it is difficult to precisely control the addition speed of the lye required for the reaction, and the lye cannot be dispersed in time after being added, resulting in the lye being unable to participate in inhibiting side reactions in time, affecting the reaction efficiency and product purity.

The air outlet hole is communicated with the exhaust hole through the air outlet pipe. A discharge pipe is fixedly installed at the bottom end of the reaction barrel. A liquid discharge valve is fixedly installed at the liquid discharge end of the discharge pipe.

[0015] A method for using a cyanate ester synthesis reaction device convenient for alkali solution preparation includes the following steps:

[0016] S1: The operator injects the alkali solution required for the cyanate ester synthesis reaction into the interior of the liquid storage bucket through the liquid adding nozzle, and then seals the inlet of the liquid adding nozzle through the sealing cap. After adding the alkali solution, the operator adds the raw materials for the cyanate ester synthesis reaction into the interior of the reaction barrel, and then releases the mounting frame and covers the cover plate on the top of the reaction barrel;

[0017] S2: By starting the driving motor to drive the turntable to rotate, the turntable drives a plurality of rotary drums to move. The rotary drums rotate self by meshing with the inner gear of the ring through the gears. The rotary drums drive the T-shaped cylinders to rotate self by transmitting torque through the limiting blocks and the limiting sliding grooves, and drive the stirring fan blades to move through the T-shaped cylinders;

[0018] S3: The sliding rod drives the T-shaped cylinder to move up and down intermittently in a reciprocating manner through the U-shaped frame. The T-shaped cylinder drives the rotating rod to move up and down intermittently in a reciprocating manner. The rotating rod makes itself rotate intermittently in a reciprocating positive and negative direction through the cooperation of the driving column and the spiral driving groove. The rotating rod drives the first bevel gear to rotate in a positive and negative direction through its own positive and negative rotation. The first bevel gear drives the stirring fan blade to rotate intermittently in a reciprocating manner by 90° through the second bevel gear.

[0019] S4: The sliding rod drives the piston plate to move up and down through intermittent reciprocating motion up and down. Then, through the action of the one-way intake valve and the one-way outlet valve, the piston plate compresses the upper cavity and the lower cavity, so that the air inside the upper cavity and the lower cavity alternately enters the inside of the liquid storage barrel, and the pressure inside the liquid storage barrel rises to a fixed value.

[0020] S5: By adjusting the inclination angle of the stirring fan blade, when the T-shaped cylinder rotates itself to drive the stirring fan blade to rotate, the mixed raw materials inside the reaction barrel can be turned up and down. When the upper liquid outlet nozzle sprays the lye from the spray hole, at this time, the inclination angle of the stirring fan blade drives the mixed raw materials inside the reaction barrel to turn down; when the lower liquid outlet nozzle sprays the lye from the spray hole, at this time, the inclination angle of the stirring fan blade drives the mixed raw materials inside the reaction barrel to turn up.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. By adjusting the inclination angle of the stirring fan blade, when the T-shaped cylinder rotates itself to drive the stirring fan blade to rotate, the mixed raw materials inside the reaction barrel can be turned up and down. Through this device, the lye can be accurately added to the cyanate ester synthesis reaction quantitatively. And through the up and down movement and rotation of the stirring fan blade, the newly added lye can be turned up and down evenly in time, ensuring that the lye can promptly and quickly promote the main reaction and inhibit the side reaction, and guaranteeing the reaction efficiency and product purity of the cyanate ester synthesis reaction.

[0023] 2. The sliding rod drives the piston plate to move up and down through intermittent reciprocating motion up and down. Then, through the action of the one-way intake valve and the one-way outlet valve, the piston plate compresses the upper cavity and the lower cavity, so that the air inside the upper cavity and the lower cavity alternately enters the inside of the liquid storage barrel, and the pressure inside the liquid storage barrel rises to a fixed value, so that the lye inside it can be sprayed out from the liquid outlet nozzle later. Through this device, it is convenient to accurately control the lye to enter the cyanate ester synthesis reaction quantitatively. BRIEF DESCRIPTION OF THE DRAWINGS

The included angle between the connecting lines of the two spray holes 29 to the rotation center of the stirring fan blade 11 is 90°. The rotation angle of the stirring fan blade 11 is 90°. The spray holes 29 are communicated with the liquid outlet ends of the liquid outlet nozzles 24. Two partition plates 1406 are symmetrically fixedly installed on the upper and lower sides of the inner wall of the rotating cylinder 9 near the cover plate 6. The sliding rod 19 penetrates through the outer surfaces of the two partition plates 1406 and is slidably installed therewith. A piston plate 1407 is fixedly installed on the outer surface of the sliding rod 19. The piston plate 1407 is slidably installed on the inner wall of the rotating cylinder 9. The piston plate 1407 is arranged between the two partition plates 1406. The piston plate 1407 divides the space between the two partition plates 1406 into an upper cavity and a lower cavity.

The T-shaped cylinder 10 drives the rotating rod 20 to intermittently move up and down reciprocally. The rotating rod 20 makes itself intermittently reciprocally rotate forward and backward through the cooperation of the driving post 21 and the spiral driving groove 28. The rotating rod 20 drives the first bevel gear 22 to rotate forward and backward through its own forward and backward rotation.

The top end of the air outlet pipe 18 abuts against the lower surface of the mounting frame 3. The air outlet hole 13 is communicated with the exhaust hole 5 through the air outlet pipe 18. A discharge pipe is fixedly installed at the bottom end of the reaction barrel 1, and a liquid outlet valve 2 is fixedly installed at the liquid outlet end of the discharge pipe.

[0046] The rotation of the turntable 12 drives the movement of the air outlet pipe 18, so that the air outlet hole 13 is communicated with the exhaust hole 5 through the air outlet pipe 18. The exhaust hole 5 is communicated with an external exhaust pipe, and the waste gas generated by the cyanate ester synthesis reaction is discharged into the waste gas treatment device for filtration to avoid the discharge of harmful gases and pollution of the environment; for the synthesis product after the cyanate ester synthesis reaction is completed, by opening the liquid outlet valve 2, it is discharged from the discharge end of the discharge pipe into the inside of the collection device for subsequent production processes.

[0047] In this embodiment, it should be noted that the depth of the arc-shaped chute provided between the outer surfaces of the outer ring 15 and the inner ring 16 is greater than the stroke of the arc-shaped slider 17 moving up and down reciprocally; the stroke of the piston plate 1407 moving up and down will not exceed the positions of the one-way intake valve 1404 and the one-way exhaust valve 1405.

[0049] S1: The operator injects the lye required for the cyanate ester synthesis reaction into the interior of the liquid storage barrel 14 through the liquid filling nozzle 1402, and then seals the inlet of the liquid filling nozzle 1402 with the sealing cap. After adding the lye, the operator adds the raw materials for the cyanate ester synthesis reaction into the interior of the reaction barrel 1, and then releases the mounting bracket 3 and covers the cover plate 6 on the top of the reaction barrel 1;

[0050] S2: By starting the driving motor 4 to drive the turntable 12 to rotate, the turntable 12 drives multiple rotating cylinders 9 to move. The rotating cylinders 9 rotate self - driven by meshing with the ring internal gear 7 through the gears 8. The rotating cylinders 9 drive the T - shaped cylinders 10 to rotate self - driven by transmitting torque through the limit blocks 26 and the limit chutes 27, and drive the stirring fan blades 11 to move through the T - shaped cylinders 10;

[0051] S3: The sliding rod 19 drives the T - shaped cylinder 10 to move up and down reciprocally intermittently through the U - shaped frame. The T - shaped cylinder 10 drives the rotating rod 20 to move up and down reciprocally intermittently. The rotating rod 20 makes itself rotate intermittently in a reciprocating positive and negative manner through the cooperation of the driving column 21 and the spiral driving groove 28. The rotating rod 20 drives the first bevel gear 22 to rotate in a reciprocating positive and negative manner through its own positive and negative rotation. The first bevel gear 22 drives the stirring fan blades 11 to rotate intermittently in a reciprocating manner by 90° through the second bevel gear 23;

[0052] S4: The sliding rod 19 drives the piston plate 1407 to move up and down reciprocally intermittently, and then through the functions of the one - way intake valve 1404 and the one - way exhaust valve 1405, the piston plate 1407 compresses the upper cavity and the lower cavity, so that the air inside the upper cavity and the lower cavity alternately enters the interior of the liquid storage barrel 14, and the pressure inside the liquid storage barrel 14 rises to a fixed value;

[0053] S5: By adjusting the inclination angle of the stirring fan blades 11, when the T - shaped cylinder 10 rotates self - driven to drive the stirring fan blades 11 to rotate, the mixed raw materials inside the reaction barrel 1 can be turned up and down. When the liquid outlet nozzle 24 above sprays the lye from the spray hole 29, at this time, the inclination angle of the stirring fan blades 11 drives the mixed raw materials inside the reaction barrel 1 to turn downwards; when the liquid outlet nozzle 24 below sprays the lye from the spray hole 29, at this time, the inclination angle of the stirring fan blades 11 drives the mixed raw materials inside the reaction barrel 1 to turn upwards.

[0054] It should be noted that when the present invention is in use, the operator hoists the mounting frame 3 by means of a hoisting tool so that the rotary drum 9 is completely exposed from the reaction barrel 1. Then, the operator injects the lye required for the cyanate synthesis reaction into the interior of the liquid storage barrel 14 through the liquid filling nozzle 1402, and then seals the inlet of the liquid filling nozzle 1402 with a sealing cap. Before adding the lye, the operator manually turns the turntable 12 to make the arc-shaped retaining ring 25 seal both liquid outlet nozzles 24, so as to prevent the just-added lye from flowing out through the liquid outlet nozzles 24 and the spray holes 29;

[0055] After adding the lye, the operator adds the raw materials for the cyanate synthesis reaction into the interior of the reaction barrel 1, then releases the mounting frame 3 and covers the cover plate 6 on the top of the reaction barrel 1. By starting the driving motor 4 to drive the turntable 12 to rotate, the turntable 12 drives multiple rotary drums 9 to move. The rotary drums 9 rotate self-drivenly by meshing with the ring internal gear 7 through the gears 8. The rotary drums 9 drive the T-shaped cylinders 10 to rotate self-drivenly by transmitting torque through the limiting blocks 26 and the limiting chutes 27. The T-shaped cylinders 10 drive the stirring fan blades 11 to move. Through the movement of the rotary drums 9, the T-shaped cylinders 10 and the stirring fan blades 11, the raw materials inside the reaction barrel 1 are stirred to facilitate the mixing of the raw materials;

[0056] Through the movement of multiple rotary drums 9, the slide rod 19 is driven to move. The slide rod 19 drives the arc-shaped slider 17 to slide along the inner wall of the arc-shaped chute provided between the outer surface of the outer ring 15 and the inner ring 16. Through the movement of the arc-shaped slider 17, the guide post 1701 is intermittently slid into the interior of the groove 1601. At this time, under the action of the spring 1703, the arc-shaped slider 17 drives the slide rod 19 to intermittently move up and down reciprocally. The slide rod 19 drives the T-shaped cylinder 10 to intermittently move up and down reciprocally through the U-shaped frame. The T-shaped cylinder 10 drives the rotating rod 20 to intermittently move up and down reciprocally. The rotating rod 20 makes itself intermittently reciprocate and rotate forward and backward through the cooperation of the driving column 21 and the spiral driving groove 28. The rotating rod 20 drives the first bevel gear 22 to rotate forward and backward through its own forward and backward rotation. The first bevel gear 22 drives the stirring fan blade 11 to intermittently reciprocally rotate 90° through the second bevel gear 23. Through the intermittent reciprocating rotation of the stirring fan blade 11 by 90°;

[0057] At the same time, through the intermittent reciprocating rotation of the stirring fan blade 11, the arc-shaped retaining ring 25 is driven to intermittently rotate 90°. The arc-shaped retaining ring 25 drives the two spray holes 29 to intermittently communicate with the upper and lower liquid outlet nozzles 24. Through the intermittent up and down reciprocating movement of the slide rod 19, the piston plate 1407 is driven to move up and down. Then, through the action of the one-way air inlet valve 1404 and the one-way air outlet valve 1405, the piston plate 1407 compresses the upper cavity and the lower cavity, so that the air inside the upper cavity and the lower cavity alternately enters the interior of the liquid storage barrel 14, and the pressure inside the liquid storage barrel 14 rises to a fixed value, so that the lye inside it can be sprayed out through the liquid outlet nozzle 24 subsequently;

[0058] By adjusting the inclination angle of the stirring fan blade 11, when the T-shaped cylinder 10 rotates itself to drive the stirring fan blade 11 to rotate, the mixed raw materials inside the reaction barrel 1 can be turned up and down. When the liquid outlet nozzle 24 above sprays out the lye from the spray hole 29, at this time, the inclination angle of the stirring fan blade 11 drives the mixed raw materials inside the reaction barrel 1 to turn downward; when the liquid outlet nozzle 24 below sprays out the lye from the spray hole 29, at this time, the inclination angle of the stirring fan blade 11 drives the mixed raw materials inside the reaction barrel 1 to turn upward. Through this device, the lye can be quantitatively and accurately added to the cyanate ester synthesis reaction, and through the up-and-down movement and rotation of the stirring fan blade 11, the just-added lye can be promptly turned up and down evenly, ensuring that the lye can promptly and quickly promote the main reaction and inhibit the side reaction, and guaranteeing the reaction efficiency and product purity of the cyanate ester synthesis reaction;

[0059] The rotation of the turntable 12 drives the movement of the air outlet pipe 18, so that the air outlet hole 13 is connected to the exhaust hole 5 through the air outlet pipe 18, and the exhaust hole 5 is connected to an external exhaust pipe to discharge the waste gas generated by the cyanate ester synthesis reaction into the waste gas treatment device for filtration, avoiding the discharge of harmful gases to pollute the environment; for the synthesis product after the cyanate ester synthesis reaction is completed, by opening the liquid outlet valve 2, it is discharged from the discharge end of the discharge pipe into the inside of the collection device for subsequent production processes.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
