[0023] See also Figure 1-7 , the present invention provides the following technical solutions: Specifically, it refers to a polymerization reaction equipment for preparing chemical raw materials, including a reactor body 1, a stirring motor 2 is arranged on the upper surface of the reactor body 1, and a stirring shaft 5 for stirring the chemical raw materials is rotatably connected to the top wall of the reactor body 1, and the lower end of the output shaft of the stirring motor 2 rotates and penetrates into the reactor body 1 and is connected to the stirring shaft 5. When in use, the stirring motor 2 is started, the output shaft of the stirring motor 2 rotates, and the stirring shaft 5 is synchronously driven to rotate at a high speed in the reactor body 1, so that the chemical raw materials in the reactor body 1 can be stirred and mixed.

[0024] A plurality of feeding pipes 4 are arranged on the upper surface of the reactor body 1, and the plurality of feeding pipes 4 are arranged in a circular array with the stirring motor 2 as the center point on the reactor body 1. A dosing tank 3 is arranged on the feeding pipe 4, and the bottom of the dosing tank 3 is arranged in a cone shape and is connected with the feeding pipe 4, so that the chemical auxiliary materials in the feeding pipe 4 can fall into the feeding pipe 4, and a valve assembly for controlling the feeding is arranged in the feeding pipe 4. The lower end of the feeding pipe 4 rotates and penetrates into the reactor body 1, and an L-shaped feeding pipe 6 is movably sleeved on the outer surface of the lower end of the feeding pipe 4, and a transmission assembly 7 for controlling the rotation of the L-shaped feeding pipe 6 is arranged on the outer surface of the stirring shaft 5, and the transmission assembly 7 includes a first gear ring 71, and the first gear ring 71 is sleeved on the outer surface of the stirring shaft 5. The top wall of the reactor body 1 is rotatably connected to a first gear 72 meshingly connected with the first gear ring 71, and the outer surface of the L-shaped feeding pipe 6 is sleeved with a second gear ring 73, and the second gear ring 73 is meshingly connected with the first gear 72. The second gear 74 is provided with a pushing assembly 8 for controlling the displacement of the second gear 74. When the stirring shaft 5 stirs the chemical raw materials in the reactor body 1, the first gear ring 71 rotates synchronously with the stirring shaft 5, thereby meshing and transmitting the rotation of the first gear 72, and the second gear ring 73 rotates synchronously under the meshing transmission of the second gear 74, so that the L-shaped feeding pipe 6 rotates in a circle at the lower end of the feeding pipe 4, and the auxiliary materials in the feeding pipe 4 fall into the L-shaped feeding pipe 6 and are thrown out. This method increases the range of chemical auxiliary material feeding, and tries to avoid the situation where the chemical auxiliary material feeding position is concentrated in one position, thereby improving the efficiency of the chemical raw material polymerization reaction. At the same time, the rotation of the L-shaped feeding pipe 6 is linked with the stirring shaft 5 through a simple structure, and no additional electric components are required to control the rotation of the L-shaped feeding pipe 6, thereby improving the utilization rate of energy, so that the device has better environmental value and environmental significance.

[0025] In the present invention, the diameter of the first gear 72 is three to five times the diameter of the first gear ring 71. Therefore, the first gear ring 71 has a deceleration effect when transmitting the first gear 72. This avoids the problem that the L-shaped feeding tube 6 rotates too fast, causing the auxiliary material to be thrown out with excessive impact force and hit the inner wall of the reactor body 1 or the stirring shaft 5, and has a certain protective effect on the inner wall of the reactor body 1 and the stirring shaft 5.

[0026] An annular groove 62 is provided on the outer surface of the feeding tube 4 near the L-shaped feeding tube 6, and an annular slider 61 is sleeved on the outer surface of the L-shaped feeding tube 6 near the annular groove 62. The annular slider 61 extends into the annular groove 62 on the side away from the L-shaped feeding tube 6 and slides in the annular groove 62. The upper and lower side surfaces of the annular slider 61 are both provided with a plurality of supporting pulleys 63 in contact with the inner wall of the annular groove 62. Therefore, the annular slider 61 is supported by the supporting pulley 63. In this way, when the L-shaped feeding tube 6 rotates at the lower end of the feeding tube 4, the annular slider 61 synchronously drives the supporting pulley 63 to slide in the annular groove 62. In this way, the friction generated when the L-shaped feeding tube 6 rotates on the surface of the feeding tube 4 is reduced, and the smoothness and stability of the L-shaped feeding tube 6 during rotation are further guaranteed.

[0027] The valve assembly includes a rotating shaft 42, both ends of which are rotatably connected to the inner wall of the feeding tube 4, the outer surface of the rotating shaft 42 is sleeved with a valve plate 43 that fits the inner wall of the feeding tube 4, and the outer surface of the feeding tube 4 is provided with a valve motor 41. The output shaft of the valve motor 41 rotates and penetrates into the feeding tube 4 and is connected to one end of the rotating shaft 42. Therefore, when the valve motor 41 is started, the output shaft of the valve motor 41 synchronously drives the rotating shaft 42 to rotate, and the valve plate 43 rotates synchronously with the rotating shaft 42, so that the amount of auxiliary material falling into the reactor body 1 can be controlled.

[0028] In order to ensure the sealing between the valve plate 43 and the feeding pipe 4, a sealing rubber ring is sleeved on the outer surface of the valve plate 43, so as to ensure the sealing between the valve plate 43 and the inner wall of the feeding pipe 4 without affecting the rotation of the valve plate 43.

[0029] The pushing assembly 8 includes a pushing rod 81, the lower end of which is arranged on the upper surface of the second gear 74, and a contraction groove 82 is provided on the top wall of the reactor body 1 near the second gear 74. The upper end of the pushing rod 81 movably penetrates the upper surface of the reactor body 1 through the contraction groove 82, and a first sleeve plate 83 is rotatably sleeved on the outer surface of the one end of the pushing rod 81 located in the contraction groove 82. A first tension spring 84 movably sleeved on the outer surface of the pushing rod 81 is provided between the first sleeve plate 83 and the top wall of the contraction groove 82. When the first tension spring 84 is not affected by the tension force, the first The tension spring 84 will generate a pulling force on the first set of plates 83, so that the initial position of the first set of plates 83 is close to the top of the contraction groove 82. At this time, the second gear 74 is pulled into the contraction groove 82 by the push rod 81, so that the second gear 74 is not engaged with the first gear 72 and the second gear ring 73. In this way, when the valve plate 43 is closed, the stirring shaft 5 cannot drive the L-shaped feeding tube 6 to rotate, thereby avoiding the problem of serious wear of the L-shaped feeding tube 6 due to continuous rotation of the stirring shaft 5, and further improving the service life of the L-shaped feeding tube 6.

[0030] The outer surface of one end of the push rod 81 outside the reactor body 1 is rotatably sleeved with a second sleeve plate 85, and a first contact rod 86 located below the valve plate 43 is provided in the feeding tube 4, and one end of the first contact rod 86 slides through the outer surface of the feeding tube 4, and a first rotating plate 87 is hinged between the end of the first contact rod 86 outside the feeding tube 4 and the outer surface of the second sleeve plate 85. When the valve plate 43 rotates downward to start conveying the auxiliary material, the valve plate 43 contacts and squeezes the end of the first contact rod 86 located in the feeding tube 4, so that the first contact rod 86 moves toward the outside of the feeding tube 4, and at the same time, the first contact rod 86 will form a thrust on the first rotating plate 87, and the first rotating plate 87 synchronously pushes the push rod 81 to move downward, and at the same time, the second gear 74 moves with the push rod 81. The rod 81 is displaced downward synchronously, and the second gear 74 is displaced downward synchronously. At the same time, the first tension spring 84 is stressed and stretched. When the valve plate 43 rotates to vertical, the second gear 74 is pushed to engage with the first gear 72 and the second gear ring 73. Therefore, through the above structure, when the valve plate 43 is opened, the L-shaped feeding pipe 6 and the transmission assembly 7 are automatically linked. When feeding is required, the L-shaped feeding pipe 6 is automatically controlled to rotate without manual control, which greatly improves the automation of the feeding structure. When the valve plate 43 is closed, the valve plate 43 does not squeeze the first contact rod 86, so the first tension spring 84 loses its pulling force, thereby pulling the second gear 74 into the contraction groove 82, so that the stirring shaft 5 cannot drive the L-shaped feeding pipe 6 to rotate.

[0031] The top of the reactor body 1 is provided with a contraction cavity 831 close to the contraction groove 82, and a fixed rod 832 with one end slidingly passing through the contraction groove 82 is provided in the contraction cavity 831, and a built-in slide plate 834 is provided at one end of the fixed rod 832 located in the contraction cavity 831, and a second tension spring 835 movably sleeved on the outer surface of the fixed rod 832 is provided between the built-in slide plate 834 and the inner wall of the contraction cavity 831. When the second tension spring 835 is not affected by the tension force, the second tension spring 835 pulls the built-in slide plate 834 to an initial position close to the contraction groove 82. At this time, one end of the fixed rod 832 extends into the contraction groove 82, and a fixed groove 833 adapted to the fixed rod 832 is provided on the surface of the first set plate 83 on one side facing the fixed rod 832, and the lower side of the first set plate 83 close to the fixed rod 832 is set as an inclined surface, so when the push rod 81 pushes the second gear 74 to move downward, The first set of plates 83 moves downward synchronously. During the displacement process, the inclined surface of the first set of plates 83 contacts one end of the fixing rod 832 located in the contraction groove 82 and squeezes the fixing rod 832, so that the fixing rod 832 gradually moves to one side of the contraction cavity 831. At the same time, the second tension spring 835 is in a stretched state. When the second gear 74 moves to engage with the first gear 72 and the second gear ring 73, the fixing rod 832 and the fixing groove 833 are in the same horizontal position, so that the fixing rod 832 moves into the fixing groove 833 under the pull of the second tension spring 835, thereby completing the fixation of the displacement of the first set of plates 83 and avoiding the problem of looseness of the first set of plates 83 as much as possible. Therefore, when the first gear 72 drives the second gear ring 73 to rotate through the second gear 74, the second gear 74 will not move up and down, further ensuring the stability of the transmission L-shaped feeding tube 6 during rotation.

[0032] The contraction chamber 831 is provided with an extrusion rod 836, the upper end of which slides through the upper surface of the reaction kettle body 1, and a second rotating plate 837 is hinged between the lower end of the extrusion rod 836 and the built-in slide plate 834, and a third rotating plate 839 is hinged to the upper end of the extrusion rod 836, and a second contact rod 838 is hinged on the other side of the third rotating plate 839, and the other end of the second contact rod 838 slides through the feeding pipe 4 and is located on the upper side of the valve plate 43. The upper surface of the valve plate 43 is provided with a trigger push plate 8310, and the shape of the trigger push plate 8310 is a right triangle, and the inclined surface contacts the second contact rod 838, so when the valve plate 43 seals the inside of the feeding pipe 4, the trigger push plate 8310 will contact the second contact rod 838. The rod 818 is squeezed, causing the second contact rod 818 to move toward the outside of the feeding tube 4, thereby generating a thrust on the third rotating plate 839, causing the third rotating plate 839 to push the extrusion rod 836 to move downward, so the second rotating plate 837 pushes the built-in slide plate 834 to move to the side away from the contraction groove 82, and the fixed rod 832 gradually moves out of the fixed groove 833, thereby being unable to restrict the first set of plates 83. Therefore, the first set of plates 83 can be pulled into the contraction groove 82 by the first tension spring 84. Through the above structure, when the valve plate 43 seals the feeding tube 4, the first set of plates 83 can be automatically unlocked, so that the second gear 74 can be moved into the contraction groove 82, thereby ensuring the use effect of the pushing assembly 8.

[0033] An anti-blocking assembly 9 is provided on one side of the batching tank 3 close to the feeding pipe 4. The anti-blocking assembly 9 includes an anti-blocking ring block 92. The anti-blocking ring block 92 is arranged inside the batching tank 3 close to the feeding pipe 4. A built-in ring groove 91 adapted to the anti-blocking ring block 92 is provided on the inner wall of the batching tank 3 close to the anti-blocking ring block 92. The upper and lower side surfaces of the anti-blocking ring block 92 are both fitted with the inner wall of the built-in ring groove 91 and slide in the built-in ring groove 91. A plurality of L-shaped levers 94 are provided on the inner side surface of the anti-blocking ring block 92. The vertical rods of the L-shaped levers 94 The lower end of the anti-blocking ring block 92 extends into the feeding pipe 4, so when the anti-blocking ring block 92 slides in the built-in ring groove 91, it can synchronously drive multiple L-shaped levers 94 to rotate. Therefore, when the solid auxiliary material in the batching tank 3 falls into the feeding pipe 4, the rotating L-shaped lever 94 can stir the solid auxiliary material at the bottom of the batching tank 3, thereby avoiding the problem of excessive solid auxiliary material accumulating at the bottom of the batching tank 3 when dropping the material, causing blockage, and further ensuring the stability of the polymerization reaction equipment during feeding, as well as the production effect of chemical raw materials.

[0034] The outer surface of the batching tank 3 is rotatably connected with a transmission shaft 95, and the transmission shaft 95 and the push rod 81 are in the same vertical position. An extension groove 98 is provided on the upper surface of the push rod 81, and the lower end of the transmission shaft 95 extends into the extension groove 98 and slides in the extension groove 98. A limiting groove 910 extending from the upper surface of the push rod 81 is provided on the inner wall of the extension groove 98. A limiting slider 99 adapted to the limiting groove 910 is provided on the outer surface of the transmission shaft 95. The limiting slider 99 slides in the limiting groove 910. Therefore, when the push rod 81 moves up and down, the limiting slider 99 slides in the limiting groove 910. When the second gear 74 meshes with the first gear 72 and the second gear ring 73 and rotates, the push rod 81 will rotate synchronously with the second gear 74. Since the transmission shaft 95 is restricted by the limiting slider 99 and the limiting groove 910, it will rotate synchronously with the push rod 81.

[0035] The outer surface of the anti-blocking ring block 92 is sleeved with a third gear ring 93, the outer surface of the transmission shaft 95 is sleeved with a transmission gear 96, and the outer surface of the batching tank 3 is provided with a connecting groove 97 connected to the built-in ring groove 91. One side of the transmission gear 96 extends into the built-in ring groove 91 through the connecting groove 97 and is meshed with the transmission gear 96. In this way, when the transmission shaft 95 rotates, the transmission gear 96 rotates synchronously with the transmission shaft 95, thereby meshing and driving the third gear ring 93 to rotate, thereby making the anti-blocking ring block 92 slide in the built-in ring groove 91. Through the above structure, the valve plate 43 automatically controls the operation of the anti-blocking component 9 after opening, and no additional electric components are required to drive it. It is completely based on the linkage of the mechanical structure, so that the component has high stability.

[0036] The working principle of the polymerization reaction equipment for preparing chemical raw materials provided by the present invention is as follows: In the first step, when auxiliary materials need to be added to the reactor body 1, the valve motor 41 is started, and the output shaft of the valve motor 41 synchronously drives the rotating shaft 42 to rotate, and the valve plate 43 rotates downward synchronously with the rotating shaft 42, and no longer blocks the feeding pipe 4, so that the auxiliary materials can fall into the reactor body 1 through the feeding pipe 4; Step 2: When the valve plate 43 rotates downward, the valve plate 43 contacts and squeezes one end of the first contact rod 86 located in the feeding tube 4, so that the first contact rod 86 moves toward the outside of the feeding tube 4. At the same time, the first contact rod 86 will form a thrust on the first rotating plate 87. The first rotating plate 87 synchronously pushes the push rod 81 to move downward. At the same time, the second gear 74 moves downward synchronously with the push rod 81. The second gear 74 moves downward synchronously. At the same time, the first tension spring 84 is stressed and stretched. When the valve plate 43 rotates to a vertical position, the second gear 74 is pushed to mesh with the first gear 72 and the second gear ring 73. In this way, when the stirring shaft 5 stirs the chemical raw materials in the reactor body 1, the first gear ring 71 rotates synchronously with the stirring shaft 5, thereby meshing and transmitting the first gear 72 to rotate, and the second gear ring 73 rotates synchronously under the meshing transmission of the second gear 74, so that the L-shaped feeding tube 6 rotates in a circle at the lower end of the feeding tube 4, and the auxiliary material in the feeding tube 4 falls into the L-shaped feeding tube 6 and is thrown out; Step 3: When the push rod 81 pushes the second gear 74 to move downward, the first set plate 83 moves downward synchronously. During the displacement process, the inclined surface of the first set plate 83 contacts one end of the fixing rod 832 located in the contraction groove 82, and squeezes the fixing rod 832, so that the fixing rod 832 gradually moves to one side of the contraction cavity 831. At the same time, the second tension spring 835 is in a stretched state. When the second gear 74 moves to be meshed with the first gear 72 and the second gear ring 73, the fixing rod 832 and the fixing groove 833 are at the same horizontal position, so that the fixing rod 832 moves into the fixing groove 833 under the pull of the second tension spring 835, thereby completing the fixing of the displacement of the first set plate 83. Step 4: The push rod 81 rotates synchronously with the second gear 74. Since the transmission shaft 95 is restricted by the limiting slider 99 and the limiting groove 910, it rotates synchronously with the push rod 81. The transmission gear 96 rotates synchronously with the transmission shaft 95, thereby meshing and driving the third gear ring 93 to rotate. Therefore, the anti-blocking ring block 92 slides in the built-in ring groove 91, and synchronously drives the multiple L-shaped levers 94 to rotate. Therefore, when the solid auxiliary material in the batching tank 3 falls into the feeding pipe 4, the rotating L-shaped lever 94 can stir the solid auxiliary material at the bottom of the batching tank 3. Step 5. After the auxiliary material is added, the control valve plate 43 rotates upward. At this time, the valve plate 43 no longer squeezes the first contact rod 86. At this time, the trigger push plate 8310 on the valve plate 43 squeezes the second contact rod 818, causing the second contact rod 818 to move toward the outside of the feeding tube 4, thereby forming a thrust on the third rotating plate 839, causing the third rotating plate 839 to push the squeezing rod 836 to move downward. Therefore, the second rotating plate 837 pushes the built-in slide plate 834 to move to the side away from the contraction groove 82, and the fixed rod 832 gradually moves out of the fixed groove 833, thereby failing to restrict the first set of plates 83. Therefore, the first set of plates 83 can be moved into the contraction groove 82 under the pull of the first tension spring 84.
