Description

Technical Field

[0001] The invention belongs to the technical field of mixing reactors, in particular to a mixing reactor for neutralization reaction of polyamide fiber raw materials. Background Art

[0002] The raw material of polyamide fiber is polyamide resin, and the fiber is made by melt spinning. Common polyamide fibers include polyhexamethylene adipate fiber (nylon 66) and polycaprolactam fiber (nylon 6).

[0003] In the synthesis process of polyamide fiber raw materials, the use of a mixing reactor is a common process method. The mixing reactor has the functions of mixing, reaction, heat exchange and external circulation, and can provide good reaction conditions such as temperature, pressure, material mixing, etc. to promote the chemical reaction.

[0004] In the synthesis of polyamide fiber raw materials, monomer raw materials such as adipic acid, hexamethylenediamine or caprolactam are added to a mixing reactor. By controlling parameters such as temperature, pressure and stirring speed, the monomer raw materials are polymerized in the reactor. During the polymerization process, catalysts, initiators or other additives may need to be added to promote the reaction or adjust the properties of the polymer.

[0005] In traditional batch reactors, reactants are often added in batches at one time rather than continuously and evenly. This method of addition may lead to uneven distribution of reactants in the batch reactor, resulting in separation, agglomeration or unevenness in the mixture, and an imbalance in the proportion of raw materials, resulting in excessive or insufficient amounts of certain components, which directly affects the effect of the polymerization reaction and the performance of polyamide fibers.

The start of the motor drives the rotation of the first rotating shaft, and the rotation of the first rotating shaft drives the rotation of the first mixing plate, so that the first mixing plate rotates to mix the materials; at the same time, when the first rotating shaft rotates, the rotation of the first rotating shaft drives the rotation of the first bevel gear, the rotation of the first bevel gear drives the rotation of the second bevel gear, the rotation of the second bevel gear drives the rotation of the third bevel gear, the rotation of the third bevel gear drives the rotation of the third rotating shaft, the rotation of the third rotating shaft drives the rotation of the second connecting plate, and the rotation of the second connecting plate drives the rotation of the third rotating shaft.

The upward movement of the protrusion drives the ring to move upward and slide out of the inner wall of the discharge pipe. The movement of the ring drives the second rack plate to move upward. The movement of the second rack plate drives the rotation of the second gear. The rotation of the second gear drives the movement of the first rack plate.

[0042] The second mixing assembly includes a second connecting plate 19 arranged inside the reactor tank body 1, a second mixing plate 20 is fixedly installed at the bottom end of the second connecting plate 19, a third rotating shaft 18 is fixedly installed inside the second connecting plate 19, a third bevel gear 17 is fixedly installed at the top end of the third rotating shaft 18, the top end of the third bevel gear 17 is meshedly connected with the second bevel gear 15, a second rotating shaft 16 is fixedly installed on one side of the second bevel gear 15, the second rotating shaft 16 is rotatably installed inside the tank cover 2, the top end of the second bevel gear 15 is meshedly connected with the first bevel gear 14, and the first bevel gear 14 is fixedly installed on the outer wall of the first rotating shaft 11.

[0043] Through the setting of the first mixing component, when the polyamide fiber raw material needs to be mixed, the required materials are firstly put into the reactor tank body 1 through the feed port 3, and then the motor 10 is started by the PLC control, and the start of the motor 10 drives the rotation of the first rotating shaft 11, and the rotation of the first rotating shaft 11 drives the rotation of the first mixing plate 12, so that the first mixing plate 12 rotates to mix the materials;

[0044] By setting the second mixing assembly, when the first rotating shaft 11 rotates, the rotation of the first rotating shaft 11 drives the rotation of the first bevel gear 14, the rotation of the first bevel gear 14 drives the rotation of the second bevel gear 15, the rotation of the second bevel gear 15 drives the rotation of the third bevel gear 17, the rotation of the third bevel gear 17 drives the rotation of the third rotating shaft 18, the rotation of the third rotating shaft 18 drives the rotation of the second connecting plate 19, the rotation of the second connecting plate 19 drives the rotation of the second mixing plate 20, so that the second mixing plate 20 rotates to mix the materials;

[0045] The first rotating shaft 11 is embedded in the third rotating shaft 18, and the first rotating shaft 11 and the third rotating shaft 18 are rotatably connected. The first bevel gear 14 and the third bevel gear 17 are symmetrically arranged, so that the third rotating shaft 18 and the first rotating shaft 11 rotate in opposite directions, so that the first mixing plate 12 and the second mixing plate 20 rotate in opposite directions, thereby improving the mixing effect of the materials;

[0046] The first mixing plate 12 is slidably connected to the second mixing plate 20. When the first mixing plate 12 contacts the second mixing plate 20, the material can be ground, thereby avoiding the situation in which the reactants are often added in batches at one time in a traditional kettle reactor, rather than added continuously and evenly. This addition method may cause uneven distribution of the reactants in the kettle reactor, resulting in separation, agglomeration or unevenness in the mixture, and an imbalance in the proportion of raw materials, so that some components are excessive or insufficient, which directly affects the effect of the polymerization reaction and the performance of the polyamide fiber. Through the coordinated arrangement of the first mixing component and the second mixing component, the first mixing plate 12 is brought into contact with the second mixing plate 20 to grind the material, thereby improving the mixing effect of the material and ensuring the quality of the finished polyamide fiber.

[0047] like Figures 1 to 11 As shown, the auxiliary mixing assembly includes a fourth rotating shaft 22 rotatably mounted inside the first mixing plate 12, a fourth bevel gear 23 is fixedly mounted on the outer wall of the fourth rotating shaft 22, the fourth bevel gears 23 are evenly arranged, one side of each fourth bevel gear 23 is meshed and connected with a fifth bevel gear 24, one side of each fifth bevel gear 24 is fixedly mounted with a fifth rotating shaft 25, the outer wall of each fifth rotating shaft 25 is fixedly mounted with a third mixing plate 26, and the third mixing plate 26 is arranged on the side wall of the first mixing plate 12.

[0048] Through the setting of the auxiliary mixing component, when the first mixing component and the second mixing component mix the polyamide fiber raw material, the motor 21 can be started by PLC control, the start of the motor 21 drives the rotation of the fourth rotating shaft 22, the rotation of the fourth rotating shaft 22 drives the rotation of the fourth bevel gear 23, the rotation of the fourth bevel gear 23 drives the rotation of the fifth bevel gear 24, the rotation of the fifth bevel gear 24 drives the rotation of the fifth rotating shaft 25, the rotation of the fifth rotating shaft 25 drives the rotation of the third mixing plate 26, thereby further improving the mixing effect of the materials.

[0049] The side walls of the second mixing plate 20 are also equipped with auxiliary mixing components.

[0050] like Figures 1 to 11 As shown, a fourth rotating shaft 22 is rotatably installed inside each first mixing plate 12, and a first gear 27 is fixedly connected to the bottom end of each fourth rotating shaft 22. Each first gear 27 is fixedly connected by a chain 28, and the first gear 27 and the chain 28 are both arranged inside the first connecting plate 13.

[0051] When the fourth rotating shaft 22 rotates, the rotation of the fourth rotating shaft 22 drives the rotation of the first gear 27, and the rotation of the first gear 27 drives the other first gears 27 to rotate through the chain 28, thereby driving the fourth rotating shafts 22 inside the other first mixing plates 12 to rotate, so as to facilitate the synchronous rotation of multiple groups of third mixing plates 26.

[0052] like Figures 1 to 11 As shown, a filter screen 37 is installed at the bottom end of the reactor tank body 1, and a baffle 42 is slidably installed inside the filter screen 37.

[0053] When the materials are mixed, the through holes in the filter screen 37 are blocked by the baffle 42;

[0054] After the materials are mixed, they can be filtered through the filter screen 37 to prevent agglomerates from remaining in the mixed materials, thereby affecting the mixing effect of the polyamide fiber raw materials and further improving the mixing effect of the raw materials.

[0055] like Figures 1 to 11 As shown, an observation window 9 is installed on the side wall of the reactor tank body 1.

[0056] When the materials are mixed, the mixing state of the materials can be observed through the observation window 9 to ensure product quality and reliability of operation.

[0057] like Figures 1 to 11 As shown, the discharge assembly includes a ball valve 8 rotatably mounted inside the discharge pipe 4, and first connecting shafts 7 are fixedly mounted on both sides of the ball valve 8, wherein a control assembly is provided on the outer wall of one of the first connecting shafts 7, and a handle 6 is fixedly mounted on one end of the other first connecting shaft 7.

The movement of the moving rod 38 drives the movement of the baffle 42 to open the through hole inside the filter screen 37, so that the material is discharged after being filtered by the filter screen 37 after mixing.

[0061] like Figures 1 to 11 As shown, the moving rod 38 is slidably installed inside the discharge pipe 4 , and a second spring 40 is provided on one side of the moving rod 38 .

[0062] When discharging, the handle 6 is rotated to move the moving rod 38 in the inner wall of the discharging tube 4, and the moving rod 38 squeezes the second spring 40, causing the second spring 40 to deform and store elastic potential energy;

[0063] After discharging, the handle 6 is rotated to separate the moving plate 41 from the moving rod 38, and the second spring 40 releases elastic potential energy to drive the moving rod 38 to reset, so that the baffle 42 moves to block the through hole of the filter screen 37, so as to facilitate mixing of the materials inside the reactor tank body 1.

[0064] like Figures 1 to 11 As shown, the moving assembly includes a fixed plate 44 slidably mounted inside the first connecting plate 13, a brush rod 29 is fixedly mounted on the bottom end of the fixed plate 44, a connecting rod 30 is fixedly connected to one side of the fixed plate 44, a first rack plate 32 is fixedly mounted on one end of the connecting rod 30, a second gear 33 is meshingly connected to one side of the first rack plate 32, a second connecting shaft 34 is fixedly mounted inside the second gear 33, a second rack plate 35 is meshingly connected to the other side of the second gear 33, a ring 36 is provided at the bottom end of the second rack plate 35, the ring 36 is slidably mounted inside the discharge pipe 4, a protrusion 43 is fixedly mounted on the bottom end of the ring 36, a wedge block 39 is provided on one side of the protrusion 43, and the wedge block 39 is fixedly mounted on one side of the moving rod 38.

[0065] Through the setting of the moving assembly, when discharging, the movement of the moving rod 38 drives the movement of the wedge block 39. The top end of the wedge block 39 is set as an inclined surface. The wedge block 39 moves and contacts with the protrusion 43, driving the protrusion 43 to slide upward. The upward movement of the protrusion 43 drives the ring 36 to move upward and slide out of the inner wall of the discharge pipe 4. The movement of the ring 36 drives the second rack plate 35 to move upward. The movement of the second rack plate 35 drives the rotation of the second gear 33. The rotation of the second gear 33 drives the movement of the first rack plate 32. The movement of the first rack plate 32 drives the movement of the connecting rod 30. The movement of the connecting rod 30 drives the movement of the fixed plate 44. The movement of the fixed plate 44 drives the brush rod 29 to slide out from the inside of the first connecting plate 13, so that the bottom end of the brush rod 29 contacts the top of the filter screen 37, which can not only improve the contact with the material to ensure that there is no agglomeration in the mixed material, but also facilitate discharging.

[0066] like Figures 1 to 11 As shown, the connecting rod 30 is slidably installed inside the first connecting plate 13 , and a first spring 31 is connected between the connecting rod 30 and the first connecting plate 13 .

[0067] When the connecting rod 30 moves, the connecting rod 30 squeezes the first spring 31, causing the first spring 31 to deform and store elastic potential energy. After the material is discharged, the first spring 31 releases the elastic potential energy to allow the brush rod 29 to slide into the first connecting plate 13 for reset.
