Description

Technical Field

[0001] This utility model belongs to the field of nylon production technology, specifically relating to a nylon polymerization device. Background Technology

[0002] Nylon is a high-performance synthetic fiber with advantages such as high strength, high abrasion resistance, good elasticity and resilience. It is widely used in textiles, apparel, industrial products, and outdoor products. Nylon polymerization is a key step in the production of nylon. Its core is to polymerize monomers into high molecular weight compounds through chemical reactions. It is mainly used to remove oligomers and unreacted monomers from chips to improve the purity and quality of the product.

[0003] Currently, in the production process of nylon, when caprolactam raw material is mixed with oxidant in the prepolymerization reactor, it is usually poured out all at once. Stirring and mixing the materials can lead to uneven mixing or reduced reaction efficiency, ultimately resulting in poor reaction effect on the materials.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a nylon polymerization apparatus.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a nylon polymerization device that can solve the problem of uneven mixing in existing nylon polymerization devices, which leads to poor material reaction.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides the following technical solution: a nylon polymerization device, comprising: a base, a polymerization tank, a stirring mechanism, a feeding mechanism, and a reset component.

[0008] The base is fixed with a mounting groove. The polymerization tank is installed in the mounting groove. The stirring mechanism is installed on the polymerization tank and includes a main shaft and multiple stirring rods, with the multiple stirring rods installed at one end of the main shaft located inside the polymerization tank.

[0009] The feeding mechanism is installed on the polymerization tank and includes: a pair of feed inlets, a pair of rotating shafts, a pair of sealing plates, a spur gear, and an intermittent gear. The pair of feed inlets are carved into the top of the polymerization tank, and a hopper and a feed pipe are respectively installed on each of the feed inlets. The pair of rotating shafts are rotatably mounted on the top of the polymerization tank, and a control rod is fixed to the upper end of each shaft. The pair of sealing plates are fixed to one end of the rotating shaft located inside the polymerization tank, and the sealing plates cover the bottom of the feed inlets. The spur gear and the intermittent gear are respectively fixed to the rotating shaft and the main shaft, and the spur gear and the intermittent gear mesh with each other. The reset assembly is installed between the control rod and the polymerization tank and is used to reset the sealing plates.

[0010] In one embodiment of this utility model, the polymerization tank includes: a tank body, a top cover, a discharge port, and a sealing plug. The tank body is mounted on the mounting groove. The top cover is mounted on the tank body, and the main shaft is rotatably mounted on the top cover. The discharge port is located at the bottom of the tank body, with one end passing through the base and located at the bottom of the base. The sealing plug is installed on the discharge port. The material to be polymerized is added to the tank body, and the main shaft drives the stirring rod to rotate for stirring. After polymerization is completed, the polymer is discharged through the discharge port.

[0011] In one embodiment of this utility model, the bottom of the base is provided with a pair of arc-shaped slots fixed on both sides of the discharge port, and the sealing plug is fixed with a pair of arc-shaped teeth that are adapted to the arc-shaped slots. After the sealing plug is inserted into the discharge port, the sealing plug is rotated so that the pair of arc-shaped teeth are engaged with the pair of arc-shaped slots, thereby fixing the sealing plug in the discharge port.

[0012] In one embodiment of this utility model, the plurality of stirring rods are arranged alternately, which can effectively improve the stirring efficiency.

[0013] In one embodiment of this utility model, a pair of fan-shaped grooves are fixed on the inner top wall of the upper cover. The sealing plate slides within the fan-shaped grooves. When the rotating shaft drives the sealing plate to rotate around the shaft, one end of the sealing plate always slides within the fan-shaped grooves, which provide support for the sealing plate. Multiple notches are cut into the fan-shaped grooves to prevent material from accumulating inside. Material that accidentally falls into the fan-shaped grooves can be pushed out through the notches when the sealing plate rotates.

[0014] In one embodiment of this utility model, the reset assembly includes a first fixing rod, a second fixing rod, and a tension spring. The first fixing rod and the second fixing rod are respectively fixed to the control rod and the polymerization tank, and the tension spring is installed between the first fixing rod and the second fixing rod. When the rotating shaft drives the sealing plate to open from the feed inlet, when the rotating shaft is not subjected to external force, the tension spring pulls the control rod to rotate back to its original position, thereby re-closing the sealing plate at the bottom of the feed inlet.

[0015] In one embodiment of this utility model, a pair of locking blocks are slidably disposed on the intermittent gear, and a pair of slots adapted to the locking blocks are carved on the main shaft. By pushing the locking blocks into the slots, the intermittent gear is driven to rotate when the main shaft rotates. When the intermittent gear is not needed to rotate, the locking blocks can be pulled out of the slots.

[0016] In one embodiment of this utility model, each of the pair of card blocks is provided with a sliding groove, and a pair of sliders adapted to the pair of sliding grooves are fixed on the intermittent gear. The card blocks are slidably positioned with the intermittent gear through the sliding grooves and sliders.

[0017] In one embodiment of this utility model, a semi-circular locking head is slidably disposed inside the locking block, and a pair of semi-circular locking grooves adapted to the semi-circular locking head are carved on the top wall of the sliding groove. The locking head is inserted into the semi-circular locking grooves to stabilize the locking block and prevent shaking. The pair of semi-circular locking grooves correspond to the positions where the locking block is inserted into the locking grooves and the positions where the locking block is completely removed from the locking grooves.

[0018] In one embodiment of this utility model, a compression spring is installed between the semi-circular clip head and the inner bottom wall of the slider. The elastic force of the compression spring is used to push the semi-circular clip head upward so that the semi-circular clip head is engaged in the semi-circular slot.

[0019] Compared with the prior art, this utility model, through related structural design, enables the gradual addition of materials during the stirring process, thereby effectively improving the uniformity of stirring and enhancing the reaction effect on the materials. Attached Figure Description

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0032] like Figure 1-8 As shown, a nylon polymerization device according to one embodiment of the present invention includes: a base 1, a polymerization tank, a stirring mechanism, a feeding mechanism 2, and a reset component.

[0033] A mounting groove 103 is fixed on the base 1. The polymerization tank is installed on the mounting groove 103. A stirring mechanism is installed on the polymerization tank. The stirring mechanism includes a main shaft 106 and multiple stirring rods 107, with the multiple stirring rods 107 installed at one end of the main shaft 106 located inside the polymerization tank.

[0034] The feeding mechanism 2 is installed on the polymerization tank and includes: a pair of feed inlets 201, a pair of rotating shafts 207, a pair of sealing plates 204, a spur gear 208, and an intermittent gear 213. The pair of feed inlets 201 are carved into the top of the polymerization tank, and a hopper 202 and a feed pipe 203 are respectively installed on the feed inlets 201. The pair of rotating shafts 207 are rotatably mounted on the top of the polymerization tank, and a control rod 209 is fixed to the upper end of each shaft 207. The pair of sealing plates 204 are fixed to one end of the rotating shafts 207 located inside the polymerization tank, and the sealing plates 204 cover the bottom of the feed inlets 201. The spur gear 208 and the intermittent gear 213 are respectively fixed to the rotating shaft 207 and the main shaft 106, and the spur gear 208 and the intermittent gear 213 mesh with each other. A reset assembly is installed between the control rod 209 and the polymerization tank, used to reset the sealing plate 204.

[0035] In operation, the main shaft 106 is first positioned at one end of the polymer tank body and requires an external drive motor 108. The drive motor 108 drives the main shaft 106 to rotate. Then, the material is added to the hopper 202, and the catalyst is conveyed from the feed pipe 203 into the tank body 101. The drive motor 108 then drives the main shaft 106 to rotate, which in turn drives the intermittent gear 213. When the toothed portion of the intermittent gear 213 rotates to the spur gear 208, the intermittent gear 213 meshes with the spur gear 208, causing the spur gear 208 to rotate. The spur gear 208, via the rotating shaft 207, drives the sealing plate 204 to rotate, causing the sealing plate 204 to move away from the bottom of the feed inlet 201. After the sealing plate 204 moves away, the material in the hopper 202 or the catalyst in the feed pipe 203 is conveyed into the tank body 101.

[0036] Furthermore, once the portion of the intermittent gear 213 with the sized part is removed from the spur gear 208, the rotating shaft 207 is no longer subjected to external force. Therefore, the reset assembly pulls the control rod 209 to rotate it back to its original position, thereby re-closing the sealing plate 204 onto the bottom of the feed inlet 201. This achieves intermittent addition of materials and catalyst to the tank 101 while simultaneously stirring, preventing uneven mixing caused by a single pour.

[0037] During stirring, the main shaft 106 is driven to rotate by the drive motor 108, and the main shaft 106 drives the stirring rod 107 to rotate, stirring the materials and catalyst in the polymerization tank, so that the materials and catalyst can carry out a chemical reaction.

[0038] like Figure 1-2 As shown, the polymerization tank includes: a tank body 101, a top cover 102, a discharge port 104, and a sealing plug 105. The tank body 101 is mounted on the mounting groove 103. The top cover 102 is mounted on the tank body 101, and the main shaft 106 is rotatably mounted on the top cover 102. The discharge port 104 is located at the bottom of the tank body 101, and one end of it passes through the base 1 and is located at the bottom of the base 1. The sealing plug 105 is installed on the discharge port 104. The material to be polymerized is added to the tank body 101, and the main shaft 106 drives the stirring rod 107 to rotate for stirring. After polymerization is completed, the polymer is discharged through the discharge port 104.

[0039] like Figure 2 As shown, a pair of arc-shaped grooves 109 are fixed on both sides of the discharge port 104 at the bottom of the base 1. A pair of arc-shaped teeth 110 that match the arc-shaped grooves 109 are fixed on the sealing plug 105. After inserting the sealing plug 105 into the discharge port 104, rotating the sealing plug 105 causes the pair of arc-shaped teeth 110 to engage with the pair of arc-shaped grooves 109, thereby fixing the sealing plug 105 in the discharge port 104. Multiple stirring rods 107 are staggered, which can effectively improve the stirring efficiency.

[0040] like Figure 4-5 As shown, a pair of fan-shaped grooves 205 are fixed on the inner top wall of the upper cover 102. The sealing plate 204 slides within the fan-shaped grooves 205. When the rotating shaft 207 drives the sealing plate 204 to rotate around the shaft 207, one end of the sealing plate 204 always slides within the fan-shaped grooves 205, and the fan-shaped grooves 205 provide support for the sealing plate 204. Multiple notches 206 are cut into the fan-shaped grooves 205. The notches 206 are used to prevent material from accumulating in the grooves. Material that accidentally falls into the fan-shaped grooves 205 can be pushed out through the notches 206 when the sealing plate 204 rotates.

[0041] like Figure 4-6 As shown, the reset assembly includes a first fixing rod 210, a second fixing rod 211, and a tension spring 212. The first fixing rod 210 and the second fixing rod 211 are respectively fixed to the control rod 209 and the polymerization tank, and the tension spring 212 is installed between the first fixing rod 210 and the second fixing rod 211. When the rotating shaft 207 drives the sealing plate 204 to open from the feed port 201, when the rotating shaft 207 is not subjected to external force, the tension spring 212 pulls the control rod 209 to rotate back to its original position, thereby re-closing the sealing plate 204 at the bottom of the feed port 201.

[0042] like Figure 4-8 As shown, a pair of locking blocks 214 are slidably mounted on the intermittent gear 213. A pair of slots 215 adapted to the locking blocks 214 are carved on the main shaft 106. By pushing the locking blocks 214 into the slots 215, the intermittent gear 213 rotates when the main shaft 106 rotates. When rotation of the intermittent gear 213 is no longer needed, the locking blocks 214 can be pulled out of the slots 215. Each pair of locking blocks 214 has a sliding groove 217 carved on it. A pair of sliders 216 adapted to the sliding grooves 217 are fixed on the intermittent gear 213. The locking blocks 214 slide against the intermittent gear 213 through the sliding grooves 217 and the sliders 216.

[0043] like Figure 4-8 As shown, a semi-circular locking head 218 is slidably disposed within the locking block 214. A pair of semi-circular slots 220 are carved into the top wall of the slide groove 217 to fit the semi-circular locking head 218. The semi-circular locking head 218 engages with the semi-circular slots 220, thereby stabilizing the locking block 214 and preventing wobbling. The pair of semi-circular slots 220 correspond to the positions where the locking block 214 is engaged in the slot 215 and where it is completely removed from the slot 215. A compression spring 219 is installed between the semi-circular locking head 218 and the inner bottom wall of the slider 216. The elastic force of the compression spring 219 pushes the semi-circular locking head 218 upwards, causing it to engage with the semi-circular slot 220.

[0044] Working Principle: Before using this device, the main shaft 106, located on the upper cover 102, needs to be connected to an external drive motor 108. Materials are added to the hopper 202, and the catalyst is conveyed to the barrel 101 through the feed pipe 203. During the stirring process, the drive motor 108 drives the main shaft 106 to rotate. The materials and catalyst to be polymerized are added to the barrel 101, and the drive motor 108 drives the main shaft 106 to rotate, which in turn drives the stirring rod 107 to rotate, stirring the materials and catalyst in the barrel 101 and causing a chemical reaction. After processing, the sealing plug 105 is removed from the discharge port 104, allowing the material to be discharged from the discharge port 104.

[0045] When adding materials and catalyst to the barrel 101, a pair of locking blocks 214 are first pushed into a pair of locking slots 215. Then, the drive motor 108 drives the main shaft 106 to rotate. The main shaft 106 drives the intermittent gear 213 to rotate. When the toothed part of the intermittent gear 213 rotates to the spur gear 208, the intermittent gear 213 meshes with the spur gear 208, driving the spur gear 208 to rotate. The spur gear 208 drives the sealing plate 204 to rotate through the rotating shaft 207, causing the sealing plate 204 to move away from the bottom of the feed inlet 201. After the sealing plate 204 is moved away, the material in the hopper 202 or the catalyst in the feed pipe 203 will be conveyed into the barrel 101.

[0046] Additionally, the rotation of the shaft 207 simultaneously drives the control rod 209 to rotate. This rotation stretches the tension spring 212. When the toothed portion of the spur gear 208 moves away from the spur gear 208, the contraction force of the tension spring 212 pulls the control rod 209 back. The control rod 209, through the shaft 207, drives the sealing plate 204 to rotate back, causing it to rotate again to the bottom of the inlet 201 and cover it. This achieves intermittent addition of materials and catalyst to the container 101 while simultaneously stirring, preventing uneven mixing caused by a single pour.
