Description

Technical Field

[0001] This utility model relates to the technical field of polyester spinning production equipment, specifically a high-pressure permeation injection device for antistatic agents in polyester spinning. Background Technology

[0002] Static electricity has long been a problem plaguing the polyester spinning industry. Due to the excellent insulating properties of polyester, static electricity is easily generated during spinning due to friction between fibers and between fibers and equipment. The accumulation of static electricity not only causes fibers to attract and entangle each other, affecting the smoothness of spinning and reducing production efficiency, but it can also lead to quality problems such as fiber breakage and fuzzing. In severe cases, it can even cause equipment failure and safety hazards, increase production costs, and affect the final quality of the product.

[0003] To address this issue, antistatic agents are typically added during polyester spinning. However, traditional methods of adding antistatic agents often have several shortcomings. For example, using conventional low-pressure injection methods, the antistatic agent struggles to penetrate evenly into the fiber, resulting in poor antistatic performance and failing to meet production requirements. Furthermore, the mixing effect of the antistatic agent with other raw materials during injection is not ideal, further impacting product performance. Existing reactor equipment also has structural limitations. The installation and disassembly of the reactor top cover are cumbersome, hindering regular inspection and maintenance of the reactor interior, affecting the normal operation and lifespan of the equipment. The design of the stirring mechanism may not achieve efficient and uniform stirring, leading to insufficient mixing and incomplete reaction of materials within the reactor. The discharge mechanism also has issues with sealing and discharge control, easily causing material leakage or poor discharge, affecting the stability of the production process and product quality. Therefore, we propose a high-pressure penetration injection device for antistatic agents in polyester spinning. Utility Model Content

[0025] Example

[0026] Please see Figures 1-5 In this embodiment of the present invention, a high-pressure permeation injection device for antistatic agent in polyester spinning includes a reaction vessel 1. The bottom of the reaction vessel 1 is provided with a support leg 11, which ensures the stability of the reaction vessel 1 in actual use.

[0027] The top of the reactor 1 is equipped with a detachable top cover 2 via a locking mechanism;

[0028] The locking mechanism includes several cavities evenly spaced inside the top cover 2. A sliding plate 21 is slidably disposed in the cavity. A rod 23 is fixedly installed on one outer wall of the sliding plate 21. Several locking blocks 24 that cooperate with the rod 23 are evenly fixedly installed on the top of the reactor 1. A support rod 22 is also fixedly installed on the other outer wall of the sliding plate 21. The support rod 22 passes through the top cover 2 and is slidably connected to the top cover 2. A spring is also sleeved on the outside of the support rod 22. One end of the spring is fixedly connected to the sliding plate 21, and the other end of the spring is fixedly connected to the inner wall of the cavity. Under the action of the spring, the connection quality between the top cover 2 and the reactor 1 is ensured. At the same time, it is also convenient to disassemble the top cover 2 to carry out maintenance work on the internal components of the reactor 1, thereby ensuring the efficiency of the reactor 1. A handle 25 is fixedly installed at the outer end of the support rod 22, and the support rod 22 can be moved by the handle 25.

[0029] The top cover 2 is also equipped with a stirring mechanism 3;

[0030] The stirring mechanism 3 includes a stirring shaft rotatably mounted on the top cover 2. Several stirring blades 31 are evenly fixedly mounted on the stirring shaft. The top cover 2 is also provided with a mounting shell. The stirring shaft passes through the mounting shell and extends into the interior of the mounting shell. A first bevel gear 32 is keyed to the stirring shaft inside the mounting shell. A second bevel gear 33 is also provided inside the mounting shell via a drive shaft. The second bevel gear 33 meshes with the first bevel gear 32. Rotating the second bevel gear 33 will drive the stirring shaft to rotate via the first bevel gear 32, thereby driving the stirring blades 31 to rotate, and thus stirring the materials inside the reactor 1. A servo motor 34 is also fixedly mounted on the side wall of the mounting shell. The power output shaft of the servo motor 34 is fixedly connected to the drive shaft via a coupling.

[0031] The reactor 1 is also equipped with a heating chamber 4. A heat source inlet pipe 5 and a heat source outlet pipe 6 are fixedly installed on the heating chamber 4. Under the action of the heating chamber 4, the inside of the reactor 1 can be heated, thereby ensuring the reaction efficiency of the reactor 1.

[0032] The bottom discharge end of the reactor 1 is also equipped with a discharge mechanism 7;

[0033] The discharge mechanism 7 includes a discharge pipe 71 fixedly installed at the discharge end of the reactor 1. A pump is fixedly installed at the discharge end of the discharge pipe 71. A sliding rod 73 is slidably installed inside the discharge pipe 71 via a mounting bracket 72. A convex ball 74 is fixedly installed at the top end of the sliding rod 73. A return spring 75 is sleeved on the outside of the sliding rod 73. One end of the return spring 75 is fixedly connected to the convex ball 74, and the other end of the return spring 75 is fixedly connected to the mounting bracket 72. When discharge is required, the pump is started. At this time, the pressure inside the discharge pipe 71 changes, causing the convex ball 74 to move downward. The material inside the reactor 1 can then be discharged through the discharge pipe 71. At the same time, the return spring 75 ensures the sealing of the discharge pipe 71 during the reaction, thereby ensuring the quality of the reaction.

[0034] A high-pressure injection device 9 is also installed on the outer wall of the other side of the reactor 1 via a fixing frame 8;

[0035] The high-pressure injection device 9 includes a fixed shell 91 mounted on the top of the fixed frame 8. A piston 92 is slidably arranged inside the upper part of the fixed shell 91. An electric push rod 93 is arranged on the top of the fixed shell 91. The end of the telescopic arm of the electric push rod 93 is fixedly connected to the piston 92. A mixing plate 95 is also rotatably arranged below the fixed shell 91. An atomizing head 94 is also arranged inside the fixed shell 91. An antistatic agent tank 97 and a high-pressure gas tank 98 are arranged on the top of the fixed frame 8 on the other side of the fixed shell 91. The antistatic agent tank 97 and the high-pressure gas tank 98 are connected to the fixed shell 91 through conduits. A one-way valve is arranged on each conduit. The fixed shell 91 is fixedly connected to the reaction vessel 1 through the feed pipe 10.

[0036] In actual use, the reactor 1 serves as the core container, with bottom supports 11 ensuring its stable placement. During operation, raw materials are injected into the reactor 1 through the high-pressure injection device 9. In the high-pressure injection device 9, the electric push rod 93 pushes the piston 92 to move within the fixed shell 91. The antistatic agent tank 97 and the high-pressure gas tank 98 deliver the antistatic agent and high-pressure gas to the fixed shell 91 through conduits with one-way valves. After mixing, the mixture is atomized by the atomizing head 94 and then enters the reactor 1 through the feed pipe 10. The mixing plate 95 rotates to assist in mixing.

[0037] The top cover 2 is connected to the reactor 1 via a locking mechanism. A spring pushes the slide plate 21 to insert the rod 23 into the locking block 24, achieving a stable connection. When maintenance is required, the handle 25 is pulled to move the support rod 22 and the slide plate 21, causing the rod 23 to disengage from the locking block 24, thus removing the top cover 2. The stirring mechanism 3 is used to stir the materials in the reactor 1. The servo motor 34 drives the drive shaft to rotate, which in turn drives the second bevel gear 33 to rotate, thereby driving the first bevel gear 32 meshing with it to rotate. The first bevel gear 32 drives the stirring shaft to rotate, and the stirring blades 31 on the stirring shaft stir the materials to promote the reaction. The heating chamber 4 introduces a heat source through the heat source inlet pipe 5 to heat the materials in the reactor 1, improving the reaction efficiency. The heat source is discharged from the heat source outlet pipe 6.

[0038] After the reaction is complete, the discharge mechanism 7 controls the discharge. When the pump starts, the pressure inside the discharge pipe 71 changes, and the convex ball 74 moves downward under pressure, allowing the material to be discharged through the discharge pipe 71. When the pump stops, the return spring 75 pushes the convex ball 74 to return to its original position, sealing the discharge pipe 71 to prevent material leakage and ensure reaction quality.
