[0002] In the production of polysulfide silane coupling agents, traditional production equipment often has many problems, which greatly limit the quality and production efficiency of the products, and also have a great impact on the environment.
[0003] With the continuous development of the chemical industry, the demand for polysulfide silane coupling agents is increasing, and the quality requirements are also getting higher and higher. However, the existing production equipment is not sophisticated enough in raw material processing and cannot effectively remove impurities and large particles in sulfur raw materials, resulting in low raw material purity and low activity, which in turn affects the efficiency of subsequent reactions and product quality.
[0004] During the reaction process, the heating method of traditional equipment is usually not uniform enough, and local overheating is prone to occur, which not only reduces the reaction rate, but also may lead to unstable product quality. In addition, poor stirring effect is also a prominent problem. The material does not flow smoothly during the reaction, and there are dead corners, making it difficult to ensure the uniformity and mixing degree of the reaction.

Its driving end extends to the interior of the second cavity 3 and is fixedly installed with a main shaft 11. The main shaft 11 rotates under the drive of the reduction motor 10, driving multiple components to work together to realize various functions in the production process.
[0022] A stirring shaft 13 is movably installed in the middle of the mixing tank 5. The stirring shaft 13 stirs the raw materials in the mixing tank 5 during the operation of the equipment to make them fully mixed. A double-helical stirring blade 16 is fixedly installed on the lower outer diameter of the stirring shaft 13.

A water inlet 8 is provided on one side of the upper part of the first cavity 2. Hot water is continuously added to the water bath 6 through the water inlet 8. A drain port 9 is provided on one side of the lower part of the first cavity 2. When it is necessary to replace the hot water or perform equipment maintenance, the water in the water bath 6 can be discharged through the drain port 9. A discharge pipe 31 is fixedly installed in the middle of the bottom end of the mixing tank 5, and the end of the discharge pipe 31 extends to the outside of the reactor 1. The discharge pipe 31 is used to discharge the mixture for subsequent treatment after the reaction is completed. Switch valves are fixedly installed on the outer diameters of the discharge pipe 31, the water inlet 8 and the drain port 9. These switch valves can control the on and off of the corresponding pipelines.

The top end of the stirring shaft 13 extends to the outside of the reactor 1 and is fixedly installed with a driven wheel 14, which rotates when driven by the driving wheel 12. The outer diameters of the driving wheel 12 and the driven wheel 14 are connected by a synchronous belt 15. Through the transmission of the synchronous belt 15, the stirring shaft 13 rotates with the main shaft 11, thereby driving the double-helix stirring blades 16 to rotate, thereby achieving the mixing and stirring of the raw materials.
[0027] Furthermore, a first bevel gear 21 is fixedly mounted on the outer diameter of the lower side of the main shaft 11. The first bevel gear 21 rotates with the main shaft 11. A short shaft 22 is movably mounted on the lower side of the inner end of the first cavity 2 and the second cavity 3. The short shaft 22 rotates driven by the first bevel gear 21. A second bevel gear 23 is fixedly mounted on one end of the short shaft 22 close to the second cavity 3.

[0028] Furthermore, a screen 26 is movably installed on the upper side of the interior of the mixing tank 5 through two return springs 27. The return springs 27 can make the screen 26 vibrate rapidly up and down under a specific force. An upper chuck 29 is fixedly installed in the middle of the screen 26, and a lower chuck 28 is fixedly installed on the lower outer diameter of the stirring shaft 13 near the screen 26. The inner ends of the lower chuck 28 and the upper chuck 29 are fixedly connected with a plurality of hemispherical protrusions 30, and the positions of the upper and lower hemispherical protrusions 30 are staggered. When the stirring shaft 13 rotates, the lower chuck 28 will be driven to rotate with it. The tooth structure formed by the hemispherical protrusions 30 staggered between the upper chuck 29 and the lower chuck 28 is used in conjunction with the return spring 27 to drive the screen 26 to vibrate rapidly up and down, so as to screen the sulfur raw material on the screen 26 and remove impurities and large particles therein, thereby improving the purity and activity of the raw material, thereby improving the efficiency of subsequent reactions and product quality.
[0029] Specifically, the main shaft 11 is driven to rotate by the reduction motor 10, and the rotating main shaft 11 will drive the top driving wheel 12 to rotate, and the synchronous belt 15 is used to drive the driven wheel 14 and the stirring shaft 13 to rotate, and the stirring shaft 13 drives the bottom double-helix stirring blade 16 to rotate, so as to achieve the mixing and stirring of the raw materials. At the same time, when the stirring shaft 13 rotates, it will drive the lower chuck 28 to rotate, and the tooth structure formed by the hemispherical protrusions 30 staggered between the upper chuck 29 and the lower chuck 28 is used to cooperate with the reset spring 27 to drive the screen 26 to vibrate up and down quickly, so as to screen the sulfur raw material on the screen 26 and remove impurities and large particles therein, so as to improve the purity and activity of the raw materials, thereby improving the efficiency of subsequent reactions and product quality.
[0030] Furthermore, an air inlet pipe 36 is fixedly connected to one side of the top of the main shaft 11, and the end of the air inlet pipe 36 extends to the inside of the mixing tank 5. An exhaust pipe 37 is fixedly connected to the other side of the top of the main shaft 11, and the end of the exhaust pipe 37 extends to the inner bottom of the third cavity 4. A one-way rubber valve 38 is installed at the connection between the air inlet pipe 36 and the exhaust pipe 37 and the second cavity 3. When the main shaft 11 rotates and drives the bidirectional spiral groove 34 to rotate, it will drive the round head pin 35 to move in the groove and make up and down reciprocating motion, thereby driving the sleeve 32 and the piston plate 33 to continue to move up and down in the second cavity 3. When the plate 33 moves downward, the air pressure in the upper space of the second cavity 3 decreases, and the external atmospheric pressure opens the one-way rubber valve 38 of the intake pipe 36, and the acidic gas such as hydrogen sulfide generated by the reaction in the mixing tank 5 enters the second cavity 3 through the intake pipe 36. When the piston plate 33 moves upward, the air pressure in the upper space of the second cavity 3 increases, and the external atmospheric pressure closes the one-way rubber valve 38 of the intake pipe 36 and opens the one-way rubber valve 38 of the exhaust pipe 37, and the gas enters the third cavity 4 through the exhaust pipe 37, and the cycle is repeated to continuously transport the gas generated by the reaction to the third cavity 4.
[0031] Furthermore, an alkaline neutralizing liquid 39 is provided inside the third cavity 4, and the alkaline neutralizing liquid 39 can absorb acidic gases such as hydrogen sulfide generated by the reaction. An activated carbon filter 40 is fixedly installed on the upper side of the interior of the third cavity 4, and the activated carbon filter 40 can adsorb unabsorbed trace gases. An exhaust hole 41 is opened on the inner top of the third cavity 4, and the treated gas is finally discharged through the exhaust hole 41 to reduce pollution to the environment.
[0032] Specifically, when the main shaft 11 rotates, it will also drive the bidirectional spiral groove 34 on the outer diameter of the middle part of the main shaft 11 to rotate. The bidirectional spiral groove 34 is formed by the end-to-end combination of two spiral grooves with opposite spiral directions. When the bidirectional spiral groove 34 rotates, it will drive the round head pin 35 to move in the groove and make up and down reciprocating motion, thereby driving the sleeve 32 and the piston plate 33 to continue to move up and down in the second cavity 3. When the piston plate 33 moves downward, the air pressure in the upper space of the second cavity 3 decreases, and the external atmospheric pressure opens the one-way rubber valve 38 of the intake pipe 36, and the acidic gas such as hydrogen sulfide generated by the reaction in the mixing tank 5 passes through the intake pipe. 36 enters the second cavity 3. When the piston plate 33 moves upward, the air pressure in the upper space of the second cavity 3 increases. The external atmospheric pressure closes the one-way rubber valve 38 of the air inlet pipe 36 and opens the one-way rubber valve 38 of the exhaust pipe 37. The gas enters the third cavity 4 through the exhaust pipe 37. The cycle repeats to continuously transport the gas generated by the reaction to the third cavity 4. After the acidic gas such as hydrogen sulfide generated by the reaction is absorbed by the alkaline neutralizing liquid 39, the activated carbon filter 40 is used to adsorb the trace gas that is not absorbed, and finally the gas is discharged through the exhaust hole 41 to reduce pollution to the environment.
[0033] Furthermore, a sealed door 42 is movably installed on one side of the top of the mixing tank 5. The sealed door 42 is convenient for adding materials and sealing, thereby ensuring the safety and stability of the production process. A control panel 43 is fixedly installed in the middle of the front end of the reactor 1. The control panel 43 is convenient for operating and monitoring the production process, so that the operator can understand the operating status of the equipment in real time and make corresponding adjustments. Support legs 44 are fixedly installed on both sides of the bottom end of the reactor 1. The support legs 44 ensure the stability of the equipment so that it will not shake or tilt during operation.
[0034] Working principle: first open the sealed chamber door 42, add the silane raw materials and sulfur raw materials required for the production of silane coupling agents into the mixing tank 5 of the first cavity 2 in sequence, and then close the sealed chamber door 42, and then start the reduction motor 10, and drive the main shaft 11 to rotate through the reduction motor 10. The rotating main shaft 11 will drive the top driving wheel 12 to rotate, and use the transmission of the synchronous belt 15 to drive the driven wheel 14 and the stirring shaft 13 to rotate. The stirring shaft 13 drives the bottom double-helix stirring blade 16 to rotate to achieve the mixing and stirring of the raw materials. At the same time, when the stirring shaft 13 rotates, it will drive the lower chuck 28 to rotate with it, and use the hemispherical protrusions 30 staggered between the upper chuck 29 and the lower chuck 28 to form a tooth structure, cooperate with the reset spring 27, and drive the screen 26 to move up and down quickly The sulphur raw material on the screen 26 is vibrated to screen and remove impurities and large particles therein, which can improve the purity and activity of the raw material, thereby improving the efficiency of subsequent reactions and the quality of products. At the same time, hot water is continuously added to the water bath 6 through the water inlet 8. The heat generated by the hot water is transmitted to the mixing tank 5 through the heat exchange plate 7, so as to achieve a uniform heating effect during the reaction, which can increase the reaction rate and reduce local overheating. At the same time, when the main shaft 11 rotates, it will also drive the first bevel gear 21 to rotate. The rotating first bevel gear 21 drives the second bevel gear 23 and the short shaft 22 to rotate through meshing transmission. The short shaft 22 drives the third bevel gear 24 to rotate and meshes with the fourth bevel gear 25, driving the fourth bevel gear 25 and the turntable 19. When the turntable 19 rotates, the rubidium magnetic ring 20 on the surface will rotate. The rotating rubidium magnetic ring 20 will absorb and drive all the metal balls 18 in the annular ball groove 17 to do circular motion. All the moving metal balls 18 are used to stir the bottom of the reaction liquid. In conjunction with the rotating double-helix stirring blades 16, two upper and lower rotating vortices are formed in the mixing tank 5, so that the material flows more smoothly during the reaction process, reducing dead angles, improving the uniformity and mixing degree of the reaction, and at the same time, a combination of mechanical stirring and magnetic stirring is adopted. While ensuring the stirring effect, the difficulty of sealing the reaction system by the stirring structure is reduced, and the risk of leakage is reduced. At the same time, when the main shaft 11 rotates, it will also drive the bidirectional spiral groove 34 on the outer diameter of the middle part of the main shaft 11 to rotate. The bidirectional spiral groove 3 4 is formed by the end-to-end combination of two spiral grooves with opposite spiral directions. When the bidirectional spiral groove 34 rotates, it will drive the round head pin 35 to move in the groove and make up and down reciprocating motion, thereby driving the sleeve 32 and the piston plate 33 to continuously move up and down in the second cavity 3. When the piston plate 33 moves down, the air pressure in the upper layer of the second cavity 3 decreases, and the external atmospheric pressure opens the one-way rubber valve 38 of the intake pipe 36, and the acidic gas such as hydrogen sulfide generated by the reaction in the mixing tank 5 enters the second cavity 3 through the intake pipe 36. When the piston plate 33 moves up, the air pressure in the upper layer of the second cavity 3 increases, and the external atmospheric pressure closes the one-way rubber valve 38 of the intake pipe 36 and opens the one-way rubber valve 38 of the exhaust pipe 37, and the gas enters the third cavity 4 through the exhaust pipe 37.The gas generated by the reaction is continuously transported to the third cavity 4 in a reciprocating cycle. The acidic gas such as hydrogen sulfide generated by the reaction is absorbed by the alkaline neutralizing liquid 39, and then the unabsorbed trace gas is adsorbed by the activated carbon filter 40, and finally discharged through the exhaust hole 41 to reduce pollution to the environment. After the reaction is completed, the switch valve of the discharge pipe 31 is opened to discharge the mixed material for subsequent neutralization treatment and distillation and filtration treatment.
