[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1

[0035] One of the existing slurry fusion devices for PBT filament production has a situation where the slurry adheres to the inner wall surface of the stirring tank during slurry fusion, resulting in insufficient mixing and affecting the quality of the final PBT filament. Please refer to Figures 1 - 8 , this embodiment provides a slurry fusion device for PBT filament production, which solves the technical problem that the slurry adheres to the inner wall of the stirring tank. The device includes a support frame 1 as a support foundation and a stirring tank 2 fixedly connected to the inside of the support frame 1. A mixing and stirring component 4 for mixing and stirring PBT raw materials is arranged inside the stirring tank 2, and a scraping component 5 is arranged inside the stirring tank 2 for scraping the additives adhering to the tank wall surface during the mixing process in cooperation with the mixing and stirring component 4. The stirring tank 2 provides a storage medium for stirring, the mixing and stirring component 4 mixes and stirs the raw materials and additives, and the scraping component 5 scrapes off the additives adhering to the tank wall.

[0036] In the traditional polyester fiber raw material slurry mixing stage, additives will adhere to the inner wall of the stirring tank, and because the amount of additives added each time is proportioned according to the amount of raw materials, too much will cause waste, and too little will result in incomplete mixing. Therefore, if the additives attached to the inner wall of the stirring tank are not mixed with the raw materials, the raw materials will not be mixed thoroughly, resulting in inferior BPT yarn products. In order to solve this problem, a scratching component 5 is proposed. The scratching component 5 includes a connecting groove 51 opened on the inner side of the top of the stirring tank 2, and a rotating disk 52 is rotatably connected to the inner side of the connecting groove 51. A plurality of vertical rods 53 are equidistantly fixedly connected to the bottom end of the rotating disk 52, and a scratching plate 54 is fixedly connected to the end of the vertical rod 53 close to the tank wall. An auxiliary discharging rod 55 is fixedly connected to the bottom end of the vertical rod 53, and a plurality of reverse stirring impellers 56 are equidistantly fixedly connected to the end of the vertical rod 53 close to the center of the tank. A docking gear 57 is rotatably connected to one side of the top of the stirring tank 2. The top of the disk 52 is fixedly connected with an annular internal tooth 58 meshing with the docking gear 57. During operation, the docking gear 57 will drive the annular internal tooth 58 meshing with it to rotate, and the annular internal tooth 58 will drive the rotating disk 52 and the vertical rod 53 connected thereto to rotate. During the rotation, the scratch plate 54 and the auxiliary discharge rod 55 connected to the outer side and the bottom end of the vertical rod 53 will scratch the tank wall and concentrate the additives attached thereto, making it easier for the additives to be mixed with the raw materials again.

[0037] In order to scrape and guide the additive scraped by the scraping plate 54 downward, the scraping plate 54 and the auxiliary discharging rod 55 are both fitted with the tank wall of the stirring tank 2 near one end of the tank wall, and the top ends of the scraping plate 54 and the auxiliary discharging rod 55 are both inclined toward the rotation direction.

[0038] In order to prevent the bottom of the vertical rod 53 from clogging the raw material and causing the transmission to be blocked, the tops of the plurality of vertical rods 53 are fixedly connected to the bottom of the rotating disk 52, and the bottoms of the vertical rods 53 do not contact the bottom of the stirring tank 2.

[0039] Example 2

[0040] On the basis of Example 1, Example 1 solves the technical problem that the slurry will adhere to the inner wall of the stirring tank, but there are still problems such as low raw material mixing efficiency and too many motorized equipment. Figures 1 - 8As shown below, the specific implementation process is as follows: In the transmission stage, in order to reduce the investment in mobile equipment, the transmission component 3 is proposed. The transmission component 3 includes a transmission motor 31 installed in the middle of the top of the mixing tank 2 through a base. The transmission end of the transmission motor 31 is connected with a driving pulley 32 outside the mixing tank 2. At the bottom end of the driving pulley 32, a driving gear 33 is fixedly connected inside the mixing tank 2. On one side inside the mixing tank 2, a reversing gear 34 meshing with the driving gear 33 is rotatably connected. On one side of the top of the mixing tank 2, a driven pulley 35 is rotatably connected. The driving pulley 32 and the driven pulley 35 are connected by a belt 36.

[0041] In order to make the rotation speed of the driven pulley 35 less than that of the docking gear 57. The bottom end of the driven pulley 35 is fixedly connected to the top end of the docking gear 57, and the diameter of the driven pulley 35 is smaller than that of the driving pulley 32.

[0042] In order to make the mixing between the raw materials and the additives more sufficient during the mixing and stirring process. The mixing and stirring component 4 includes a transfer pipe 41 arranged in the middle inside the mixing tank 2. A number of stirring impellers 42 are fixedly connected at equal intervals on the outside of the transfer pipe 41. The top end of the transfer pipe 41 is fixedly connected with a top plate 43. The top end of the top plate 43 is fixedly connected with a connecting gear 44. A number of discharge windows 45 are arranged at equal intervals above the outside of the transfer pipe 41. A guiding hopper 46 is fixedly connected below the outside of the transfer pipe 41. A number of feeding windows 47 are arranged at equal intervals below the outside of the transfer pipe 41. A lifting screw 48 is rotatably connected inside the transfer pipe 41. During the operation, the driving gear 33 will drive the connected lifting screw 48 to rotate, and the driving gear 33 will also drive the reversing gear 34 meshing with it to rotate, and the reversing gear 34 will drive the connecting gear 44 meshing with it to rotate. The top plate 43 and the connecting gear 44 are rotatably connected to the bottom end of the driving gear 33. The connecting gear 44 meshes with the reversing gear 34, and the connecting gear 44 will drive the connected connecting gear 44 to rotate, and the connecting gear 44 will drive the connected transfer pipe 41 to rotate. During this period, the transfer pipe 41 will drive the stirring impellers 42 fixedly connected to its outside to rotate, so as to achieve stirring. During this period, the lifting screw 48 will push the raw materials into the inside of the transfer pipe 41 through the feeding windows 47 opened at the bottom end of the transfer pipe 41 and discharge them through the discharge windows 45, thereby realizing the stirring and turning up of the raw materials, so that the mixing is more sufficient.

[0043] In order to prevent the stirring impellers 42 from conflicting with the reverse stirring impellers 56. The bottom end of the transfer pipe 41 is rotatably connected to the bottom of the mixing tank 2, and a number of stirring impellers 42 and reverse stirring impellers 56 are not on the same horizontal line.

[0044] In order to facilitate smoother discharging after stirring is completed. One side of the bottom end of the stirring tank 2 is movably connected with a discharging baffle 6. The bottom end of the discharging baffle 6 is fixedly connected with a discharging auxiliary hopper 7 outside the stirring tank 2. One side of the top end of the stirring tank 2 is fixedly connected with a feeding hopper 8. The feeding hopper 8 is communicated with the stirring tank 2. The discharging end of the feeding hopper 8 extends between the top plate 43 and the rotating disk 52. The edge of the guiding hopper 46 extends to the middle of the top end of the discharging baffle 6. One ends of a plurality of auxiliary discharging rods 55 far away from the transfer pipe 41 do not contact the guiding hopper 46.

[0045] It should be noted that in this text, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device.

[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
