Description

Technical Field

[0001] This utility model relates to the field of polyester filament production technology, specifically to a polymerization reactor for preparing raw materials for polyester filament production. Background Technology

[0002] Polyester is an important type of synthetic fiber and is the commercial name for polyester fiber in my country. It is a fiber-forming polymer—polyethylene terephthalate (PET)—obtained from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation reactions. The fiber is then spun and post-processed. Major types of polyester include staple fiber, drawn yarn, textured yarn, decorative filament, industrial filament, and various differentiated fibers. In the processing of polyester filament, polycondensation reactions of the raw materials are required. Existing polycondensation reaction tanks result in poor uniformity of mixing the raw materials, and the raw materials after the polycondensation reaction need to be transported to the next process. However, existing conveying devices are not continuous and have complex structures, increasing the processing time of polyester filament and reducing work efficiency. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the prior art by providing a polymerization reactor for preparing raw materials for polyester filament production. This solves the problem mentioned in the background art that the existing polycondensation reactors have poor uniformity in polycondensation mixing of raw materials, and the raw materials after polycondensation need to be transported to the next process. However, the existing conveying devices are not continuous and have complex structures, which increases the operation time of polyester filament production and processing and reduces work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a polymerization reactor for preparing raw materials for polyester filament production, comprising a conveying and driving structure, wherein a reactor body structure is fixedly installed above the conveying and driving structure;

[0005] The conveying drive structure includes a conveying box with connecting columns fixedly installed on both sides, and a connecting block fixedly installed on the top of the conveying box, with through holes opened between the connecting blocks;

[0006] The bottom of the conveyor box is fitted with a discharge pipe with a control valve, and an auger rod is rotatably installed through the connecting column inside the conveyor box. At the same time, a drive gear is fixedly installed at one end of the auger rod.

[0007] By adopting the above technical solution, the auger rod is installed to achieve rotational conveying.

[0008] Preferably, a bearing bracket is fixedly installed above the connecting column, and a drive motor is fixedly installed above the connecting column. At the same time, a drive gear is installed through the output end of the drive motor, and the drive gear is meshed with the driving gear through a chain.

[0009] By adopting the above technical solution, the connecting columns are used to achieve installation and fixation.

[0010] Preferably, a connecting shaft that passes through the bearing bracket is welded and fixedly installed at one end of the drive gear, and a drive bevel gear is fixedly installed at one end of the connecting shaft.

[0011] By adopting the above technical solution, the connecting shaft can be used to fix the object and drive rotation adjustment.

[0012] Preferably, the vessel structure includes a vessel body fixed above the connecting block, and a discharge valve pipe below the vessel body is installed and connected to a through hole. At the same time, a bearing mounting bracket is fixedly installed above the vessel body, and a driven bevel gear is installed in the bearing mounting bracket. A through pipe is fixedly installed at the bottom of the driven bevel gear, and a matching pipe through the through pipe is fixedly installed at the bottom of another driven bevel gear.

[0013] By adopting the above technical solution, the bearing bracket is designed to facilitate the installation and rotation of the bearing.

[0014] Preferably, a connecting rod for fixing the first scraper is welded and fixed to the surface of the through pipe, and a stirring shaft is fixedly installed at the bottom of the matching pipe. At the same time, a second scraper is fixedly installed at the bottom of the stirring shaft through another matching pipe and another connecting rod.

[0015] By adopting the above technical solution, the matching pipes are installed to achieve the purpose of connection and matching.

[0016] Preferably, another matching pipe has a stirring shaft fixedly installed at the bottom, extending inside the discharge valve pipe, and the bearing mounting bracket has a driving gear that meshes with the driven bevel gear.

[0017] By adopting the above technical solution, the set stirring shaft can achieve rotational stirring.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the polymerization reactor used for preparing raw materials for polyester filament production...

[0019] (1) This case solves the problem of poor uniformity of polycondensation mixing of raw materials in existing polycondensation reaction tanks by setting the reactor body structure. When the active bevel gear drives the driven bevel gear to rotate under force, it drives the first scraper and the second scraper to rotate relative to each other. When the first scraper and the second scraper rotate relative to each other, the raw materials inside the reactor body are fully rotated and stirred. In addition, the first scraper and the stirring shaft not only facilitate scraping and cleaning of the inner wall of the reactor body, but also effectively prevent material discharge blockage.

[0020] (2) By setting up a conveyor drive structure, the problem of needing to transport the raw materials after the polycondensation reaction to the next process is solved. However, the existing conveying device is not continuous and has a complex structure, which increases the operation time of polyester filament production and processing and reduces work efficiency. When the material reaction is successful, the operator opens the discharge valve pipe and the material is transported into the conveyor box. The material entering the conveyor box is continuously conveyed and discharged through the auger rod. At the same time, the single drive motor set in the conveyor drive structure effectively drives the reactor structure and the components in the conveyor drive structure to be synchronously driven and adjusted, thereby avoiding the excessive installation of drive equipment and the resulting high overall equipment cost.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a polymerization reactor for preparing raw materials for polyester filament production, such as... Figure 1 and Figure 2As shown, the system includes a conveyor drive structure 1, which comprises a conveyor box 101 with connecting columns 102 fixedly installed on both sides. A connecting block 103 is fixedly installed on the top of the conveyor box 101, and a through hole 104 is provided between the connecting blocks 103. A discharge pipe with a control valve is embedded and fixedly installed at the bottom of the conveyor box 101. An auger rod 105 is rotatably installed inside the conveyor box 101 through the connecting columns 102, and a drive gear 106 is fixedly installed at one end of the auger rod 105. A bearing bracket 107 is fixedly installed on the top of the connecting columns 102. A drive motor 108 is fixedly installed on the top of the vessel body structure 2. A drive gear 109 is installed through the output end of the drive motor 108. The drive gear 109 is meshed with the drive gear 106 via a chain 1010. A connecting shaft 1011 is welded and fixedly installed at one end of the drive gear 109 through the bearing bracket 107. A drive bevel gear 1012 is fixedly installed at one end of the connecting shaft 1011. The above components constitute a rotary drive structure. The rotary drive structure constituted by the above components can effectively drive the components in the vessel body structure 2 to rotate synchronously and adjust.

[0028] like Figure 3 and Figure 4 As shown, a vessel structure 2 is fixedly installed above the conveyor drive structure 1. The vessel structure 2 includes a vessel body 201 fixed above the connecting block 103, and the discharge valve pipe below the vessel body 201 is matched and connected to the through hole 104. At the same time, a bearing mounting bracket 202 is fixedly installed above the vessel body 201. A driven bevel gear 203 is matchedly installed in the bearing mounting bracket 202, and a through pipe 204 penetrating the vessel body 201 is fixedly installed at the bottom of the driven bevel gear 203. At the same time, a matching pipe 205 penetrating the through pipe 204 is fixedly installed at the bottom of another driven bevel gear 203. A first scraper 206 is welded and fixed to the surface of the through pipe 204. A connecting rod is fixedly installed, and a stirring shaft 207 is fixedly installed at the bottom of the matching pipe 205. At the same time, a second scraper 208 is fixedly installed at the bottom of the stirring shaft 207 through another matching pipe 205 and another connecting rod. A stirring shaft 207 extending into the discharge valve pipe is fixedly installed at the bottom of another matching pipe 205. A drive gear 109 that meshes with the driven bevel gear 203 is rotatably installed on the bearing mounting bracket 202. The relative rotation adjustment structure formed by the above components effectively drives the first scraper 206 and the second scraper 208 to rotate relative to each other, thereby fully rotating and stirring the raw materials inside the vessel body 201.

[0029] In the above scheme, when the raw materials need to react, the operator places the raw materials inside the reactor body 201 and drives the active bevel gear 1012 to rotate via the drive motor 108. When the active bevel gear 1012 rotates, it drives the driven bevel gear 203 to rotate under force, thereby causing the first scraper 206 and the second scraper 208 to rotate relative to each other. When the first scraper 206 and the second scraper 208 rotate relative to each other, the raw materials inside the reactor body 201 are fully rotated and stirred. After the raw materials have been fully stirred and reacted, the operator opens the discharge valve pipe and the material is transported into the conveyor box 101. The material entering the conveyor box 101 is continuously conveyed and discharged through the auger rod 105.
