Description

Technical Field

[0001] The utility model relates to the technical field of resin production, in particular to a resin production polycondensation kettle capable of preventing raw materials from splashing. Background Art

[0002] Resin production involves esterification polycondensation reaction, so a polycondensation kettle is needed in the process of resin production. A polycondensation kettle is a device specially used for polycondensation reaction, which is widely used in chemical industry, pharmaceutical industry and food processing. Polycondensation reaction is a polymerization reaction in which monomers are connected into polymer chains through the formation of covalent bonds, while releasing water or other small molecules. The design and construction of the polycondensation kettle are to meet the specific needs of the polycondensation reaction. In the prior art, when using the polycondensation kettle in the process of resin production, it is usually necessary to add various additive raw materials. The existing ones are added from the top addition port of the polycondensation kettle. When adding, the additives are added. The additive will drip directly onto the liquid surface inside the polycondensation kettle. This method makes it difficult to evenly add the additive raw materials into the polycondensation kettle, and it will also cause the additive to splash onto the inner wall of the polycondensation kettle. When the splashed additive raw materials adhere to the inner wall of the polycondensation kettle and cannot participate in the polycondensation reaction in time, the actual concentration of the additive in the reaction system will be inconsistent with the expectation, which will further affect the reaction rate and the molecular weight distribution of the product. In addition, when the additive is corrosive, the additive splashed onto the inner wall of the polycondensation kettle will also corrode the polycondensation kettle, thereby shortening its service life. Therefore, in response to the above problems, a resin production polycondensation kettle with anti-raw material splashing is proposed. Utility Model Content

[0003] The technical problem to be solved by the utility model overcomes the existing defects and can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A resin production polycondensation kettle that prevents raw materials from splashing includes a polycondensation kettle, the top of the polycondensation kettle is fixedly connected to a motor, the end of the motor's main shaft is fixedly connected to a fixed shaft, the bottom end of the fixed shaft is fixedly connected to a stirring rod, the outer top end of the fixed shaft is rotatably connected to a rotating sleeve, the outer side of the motor's main shaft is fixedly connected to a driving gear, the bottom end of the rotating sleeve is connected to a discharge pipe, the outer side of the rotating sleeve is rotatably connected to a fixed sleeve, the right end of the fixed sleeve is connected to a feed pipe that passes through the polycondensation kettle, and the feed pipe is fixedly connected to the polycondensation kettle, the top end of the feed pipe is connected to a feed hopper, and the inner top end of the feed hopper is spirally connected to a threaded plug.

[0006] As a further improvement of the present invention, a bearing is fixedly connected to the center of the inner side of the rotating sleeve, and the bearing is fixedly connected to the fixed shaft.

[0007] As a further improvement of the present invention, the outer side of the driving gear is meshedly connected with a driven gear, the outer side of the driven gear is meshedly connected with a gear ring, and the gear ring is fixedly connected to the rotating sleeve.

[0008] As a further improvement of the present invention, there are four discharge pipes, which are symmetrically distributed at the bottom of the rotating sleeve, and the discharge pipes are arranged at an angle.

[0009] As a further improvement of the present invention, a scraper is slidably connected to the right end of the inner side of the feed pipe, and the right end of the scraper is fixedly connected to a fixed rod passing through the feed pipe. A threaded shaft passing through the fixed rod is spirally connected to the outer side of the fixed rod, and the threaded shaft is rotatably connected to the polycondensation kettle.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. A resin production polycondensation kettle that prevents raw material splashing. The device comprises a feed hopper, a feed pipe, a rotating sleeve, a driving gear, a driven gear, a gear ring, a discharge pipe, and a stirring rod. When adding additive raw materials to the polycondensation kettle during the resin production process, the additive raw materials are first placed in the feed hopper, and then the additives enter the rotating sleeve through the feed pipe. Because the motor drives the stirring rod to rotate via a fixed shaft, it also drives the driving gear to engage with the driven gear. At this time, the driven gear engages the gear ring, further controlling the rotating sleeve to drive the discharge pipe inserted into the reaction material to rotate. The additive raw materials entering the rotating sleeve are continuously thrown out through the inclined discharge pipe and added to the polycondensation kettle. Then, the stirring rod, which rotates in the opposite direction to the discharge pipe, continuously and uniformly stirs the additive raw materials added to the reaction material. By throwing the additive raw materials into the reaction material through the rotating discharge pipe and then uniformly stirring them by the rotating stirring rod, the uniformity of the additive addition is improved, and the phenomenon of the additive raw materials splashing onto the inner wall of the reactor when added is avoided, thereby ensuring the service life of the polycondensation kettle.

[0012] 2. A resin production polycondensation kettle that prevents raw materials from splashing. Through the provided threaded shaft, fixed rod, scraper and feed pipe, after the additive raw materials are added into the polycondensation kettle, the threaded shaft is spirally connected to the fixed rod by rotating, and the fixed rod is further controlled to drive the scraper to scrape the inner wall of the feed pipe, so that the additive raw materials attached to the inner wall of the feed pipe can be scraped into the rotating sleeve. Then, when all the additive raw materials in the rotating sleeve are thrown out and added, the actual concentration of the additive in the reaction system is guaranteed to be consistent with the expected concentration, avoiding affecting the reaction rate and the molecular weight distribution of the product.

Based on the specific embodiments of the present invention, all other specific embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] Example 1

[0020] like Figure 1-3 As shown, a resin production polycondensation kettle that prevents raw materials from splashing includes a polycondensation kettle 1, the top of the polycondensation kettle 1 is fixedly connected to a motor 2, the end of the main shaft of the motor 2 is fixedly connected to a fixed shaft 3, the bottom end of the fixed shaft 3 is fixedly connected to a stirring rod 4, the top end of the outer side of the fixed shaft 3 is rotatably connected to a rotating sleeve 5, the outer side of the main shaft of the motor 2 is fixedly connected to a driving gear 7, the bottom end of the rotating sleeve 5 is connected to a discharge pipe 11, the outer side of the rotating sleeve 5 is rotatably connected to a fixed sleeve 10, the right end of the fixed sleeve 10 is connected to a feed pipe 12 that passes through the polycondensation kettle 1, and the feed pipe 12 is fixedly connected to the polycondensation kettle 1, the top end of the feed pipe 12 is connected to a feed hopper 13, and the top end of the inner side of the feed hopper 13 is spirally connected to a threaded plug 14.

[0021] Example 2

[0022] like Figure 2 As shown, in order to solve the problem of large friction between the rotating sleeve 5 and the fixed shaft 3 when rotating, a bearing 6 is fixedly connected to the center of the inner side of the rotating sleeve 5, and the bearing 6 is fixedly connected to the fixed shaft 3. By connecting the fixed shaft 3 to the rotating sleeve 5 through the bearing 6, large friction between the rotating sleeve 5 and the fixed shaft 3 when rotating is avoided.

[0023] Example 3

[0024] like Figure 2-3 As shown, in order to solve the problem that the additive raw material is not stirred very well after being discharged through the discharge pipe 11, the outer side of the driving gear 7 is meshed with a driven gear 8, and the outer side of the driven gear 8 is meshed with a gear ring 9, and the gear ring 9 is fixedly connected to the rotating sleeve 5. In the process of the motor 2 driving the stirring rod 4 to rotate through the fixed shaft 3, the motor 2 simultaneously drives the driving gear 7 to mesh with the driven gear 8, and further after meshing the gear ring 9, the rotating sleeve 10 is controlled to drive the discharge pipe 11 inserted into the reaction material to rotate in the opposite direction to the rotation direction of the stirring rod 4, so that the additive raw material is better stirred after being discharged through the discharge pipe 11.

[0025] Example 4

[0026] like Figure 2-3 As shown, in order to solve the problem that a large amount of additive raw materials will adhere to the inner wall of the discharge pipe 11 during the addition process, there are 4 discharge pipes 11, and the discharge pipes 11 are symmetrically distributed at the bottom of the rotating sleeve 5. The discharge pipes 11 are tilted. By tilting the discharge pipes 11, the additive raw materials attached to the inner wall of the discharge pipe 11 are thrown out when the discharge pipe 11 is controlled to rotate, thereby avoiding the phenomenon that a large amount of additive raw materials adhere to the inner wall of the discharge pipe 11 during the addition process.

[0027] Example 5

[0028] like Figure 1-2 As shown, in order to solve the problem of inconvenience in processing the additive raw materials attached to the inner wall of the feed pipe 12, a scraper 15 is slidably connected to the right end of the inner side of the feed pipe 12, and the right end of the scraper 15 is fixedly connected to a fixed rod 16 that passes through the feed pipe 12. The outer side of the fixed rod 16 is spirally connected to a threaded shaft 17 that passes through the fixed rod 16, and the threaded shaft 17 is rotatably connected to the polycondensation reactor 1. By rotating the threaded shaft 17 and spirally connecting it with the fixed rod 16, the fixed rod 16 is further controlled to drive the scraper 15 to scrape the inner wall of the feed pipe 12, which facilitates the scraping of the additive raw materials attached to the inner wall of the feed pipe 12 for addition processing.

[0029] In this embodiment, when adding additive raw materials to the polycondensation reactor 1 during the production of resin by the device, first rotate the threaded plug 14 to disengage the spiral connection with the feed hopper 13, and then put the additive in the feed hopper 13. At this time, the additive will enter the rotating sleeve 5 through the feed pipe 12. Because at this time, the motor 2 will also drive the driving gear 7 to engage the driven gear 8 in the process of driving the stirring rod 4 to rotate through the fixed shaft 3. At this time, the driven gear 8 engages the gear ring 9, and the rotating sleeve 10 is further controlled to drive the discharge pipe 11 inserted into the reaction material to rotate in the opposite direction to the rotation direction of the stirring rod 4. The additive raw materials entering the rotating sleeve 5 will be continuously thrown out through the inclined discharge pipe 11 and added to the polycondensation reactor 1 , and then the stirring rod 4 rotating in the opposite direction to the discharge pipe 11 will continuously and evenly stir the additive raw materials added to the reaction material, thereby achieving uniform addition of the additives under the premise of preventing splashing. After the additive raw materials are added to the condensation reactor 1, the threaded shaft 17 is spirally connected to the fixed rod 16 by rotating the threaded shaft, and the fixed rod 16 is further controlled to drive the scraper 15 to scrape the inner wall of the feed pipe 12. The additive raw materials attached to the inner wall of the feed pipe 12 can be scraped into the rotating sleeve 5. Then, when all the additive raw materials in the rotating sleeve 5 are thrown out and added, it is ensured that the actual concentration of the additive in the reaction system is consistent with the expected concentration, avoiding affecting the reaction rate and the molecular weight distribution of the product.
