Description

Technical Field

[0001] This utility model relates to the field of nylon chip technology, and in particular to a black nylon chip extraction water recovery system. Background Technology

[0002] Nylon chips are a polymer compound produced by polymerizing caprolactam as a raw material with the addition of certain additives under specific process conditions, followed by processes such as injection molding, pelletizing, extraction, and vacuum or hot nitrogen drying. During the production of nylon chips, the monomer (caprolactam) in the nylon chips needs to be extracted with water, during which the monomer dissolves into the extraction water. Since the extraction water contains a large amount of monomer (concentration up to 10%), direct discharge not only causes environmental pollution but also wastes the monomer, increases production costs, and reduces economic benefits. Therefore, it is necessary to recycle and reuse the extraction water.

[0003] Nylon chips require extraction before production. During extraction, extractant water is added to extract caprolactam. The extracted raw material is then processed into nylon chips. During extraction, some of the raw material easily becomes part of the extractant water. Directly discharging this extractant water not only wastes resources but also pollutes the environment. Therefore, it is necessary to add back-extractants to the extractant water for recycling. Current technology relies solely on the natural sedimentation of the extractant water and back-extractants for water recycling, resulting in low recycling efficiency. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a black nylon chip extraction water recovery system.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a black nylon chip extraction water recovery system, comprising a recovery tank for storing nylon chip extraction water, support legs arrayed on the bottom surface of the recovery tank, a feed pipe installed at the upper end of the recovery tank, a discharge pipe installed at the lower end of the recovery tank, a sealing door provided on the outer wall of the recovery tank, an observation window provided on the sealing door for observing the inside of the recovery tank, and a stirring mechanism for stirring the nylon chip extraction water and back-extracted material provided inside the recovery tank.

[0006] By adopting the above technical solution, after the extraction of nylon chip raw materials is completed, the extraction water is fed into the recovery tank through the feed pipe. Subsequently, the back-extracted material is fed into the recovery tank through the feed pipe. At this time, the material is stirred by a stirring mechanism, which improves the recovery efficiency during this process.

[0007] Furthermore, the stirring mechanism includes a motor fixedly mounted on the upper surface of the recycling tank, a stirring rod fixedly mounted on the end of the motor output shaft, and a plurality of stirring blades rotatably mounted on the outer wall of the stirring rod. The stirring rod is provided with a drive assembly for driving the stirring blades to rotate.

[0008] Furthermore, the outer wall of the stirring rod is provided with multiple rotating grooves. The driving assembly includes multiple first bevel gears arrayed on the outer wall of the stirring rod, multiple rotating rods respectively rotatably disposed in the multiple rotating grooves, and multiple second bevel gears respectively sleeved on both sides of the multiple rotating rods. The first bevel gears and the second bevel gears mesh with each other. The first bevel gears are fixed to the stirring rod. The two ends of the rotating rods are respectively fixed to the adjacent stirring blades. The second bevel gears are fixed to the rotating rods.

[0009] By adopting the above technical solution, when the staff needs to stir the extracted water and back-extracted material in the recovery tank, the staff needs to start the motor, which will cause the motor output shaft to rotate. This will cause the stirring rod and stirring blade to rotate under the action of the motor output shaft, thereby fully stirring the extracted water and back-extracted material. During this process, when the stirring rod rotates, the first bevel gear rotates synchronously with the stirring rod, which in turn causes the second bevel gear to rotate under the action of the first bevel gear. This, in turn, causes the rotating rod to rotate under the action of the second bevel gear, and the stirring blade to rotate under the action of the rotating rod, thereby further improving the recovery efficiency.

[0010] Furthermore, an annular groove is formed on the inner wall of the rotating groove, and an annular block is rotatably arranged in the annular groove, the annular block being fixed to the rotating rod.

[0011] By adopting the above technical solution, when the rotating rod rotates, the annular block rotates synchronously with the rotating rod under the action of the rotating rod. During this process, the annular block limits the rotating rod, thereby reducing the probability of the rotating rod slipping and improving the stability of the device.

[0012] Furthermore, a first gear is fixedly installed on the outer wall of the motor output shaft, a second gear meshes with one side of the first gear, a gear ring meshes with the side of the second gear away from the first gear, and a stirring element is fixedly installed at the lower end of the gear ring.

[0013] By adopting the above technical solution, when the motor output shaft rotates, the first gear rotates synchronously with the motor output shaft, which in turn causes the second gear to rotate in the opposite direction under the action of the first gear. This causes the gear ring to rotate synchronously in the opposite direction under the action of the second gear, thereby causing the stirring element to rotate synchronously in the opposite direction under the action of the gear ring. This allows the stirring element to stir the extracted water and the back-extracted material, thereby further improving the recovery efficiency.

[0014] Furthermore, a blocking ring is fitted on the outer wall of the stirring rod, the blocking ring is rotatably connected to the stirring rod, and a limit rod is fixedly installed on the outer wall of the blocking ring, the limit rod being rotatably connected to the second gear.

[0015] By adopting the above technical solution, when the stirring rod rotates, the blocking ring rotates relative to the stirring rod. During this process, the blocking ring and the limiting rod limit the second gear, thereby reducing the probability of the second gear shaking and improving the stability of the device.

[0016] Furthermore, the output shaft of the motor is fitted with a limiting ring, which is rotatably connected to the end of the motor output shaft. The two ends of the two limiting rings are respectively fixed to the stirring component by limiting members.

[0017] Furthermore, two blocking plates are fixedly installed at the end of the motor output shaft, and the upper and bottom surfaces of the two blocking plates abut against the bottom and upper surfaces of the limiting ring, respectively.

[0018] By adopting the above technical solutions, the limiting ring, limiting component, and blocking plate reduce the probability of the gear ring moving up and down, thereby improving the stability of the device.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. In this application, after the nylon chip raw material has been extracted, the worker puts the extraction water into the recovery tank through the feed pipe. Subsequently, the worker puts the back-extracted material into the recovery tank through the feed pipe. At this time, the worker stirs the material using a stirring mechanism, which improves the recovery efficiency during this process.

[0021] 2. In this application, when the staff needs to stir the extract water and back-extracted material in the recovery tank, the staff needs to start the motor, which will cause the motor output shaft to rotate, thereby causing the stirring rod and stirring blade to rotate under the action of the motor output shaft, thus fully stirring the extract water and back-extracted material. During this process, when the stirring rod rotates, the first bevel gear rotates synchronously with the stirring rod, which in turn causes the second bevel gear to rotate under the action of the first bevel gear, thereby causing the rotating rod to rotate under the action of the second bevel gear, and thus causing the stirring blade to rotate under the action of the rotating rod, thereby further improving the recovery efficiency.

[0022] 3. In this application, when the rotating rod rotates, the annular block rotates synchronously with the rotating rod under the action of the rotating rod. During this process, the annular block limits the rotating rod, thereby reducing the probability of the rotating rod sliding and thus improving the stability of the device.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-4 As shown in the figure, this application discloses a black nylon chip extraction water recovery system, including a recovery tank 1, support legs 11, feed pipe 12, discharge pipe 13, sealing door 14, stirring mechanism 2, drive assembly 3, annular block 41, first gear 5, second gear 51, gear ring 52, and stirring element 53. The recovery tank 1 is a hollow cylindrical structure used to store nylon chip extraction water. The support legs 11 are cylindrical rod-shaped structures, with multiple support legs arranged in an array on the bottom surface of the recovery tank 1. The feed pipe 12 is installed at the upper end of the recovery tank 1 for feeding materials into the recovery tank 1. The discharge pipe 13 is installed at the lower end of the recovery tank 1 for discharging materials, and a control valve (not shown in the figure) is provided on the discharge pipe 13 for controlling the opening and closing of the discharge pipe 13. The sealing door 14 is located on the outer wall of the recovery tank 1, and an observation window (not shown in the figure) is provided on the sealing door 14 for observing the interior of the recovery tank 1.

[0030] After the extraction of nylon chip raw materials is completed, the extraction water is fed into the recovery tank 1 through the feed pipe 12. Subsequently, the back-extracted material is fed into the recovery tank 1 through the feed pipe 12. At this point, the material is stirred using the stirring mechanism 2, which improves the recovery efficiency during this process.

[0031] A stirring mechanism 2 is installed inside the recovery tank 1 to stir the nylon chip extraction water and back-extract. The stirring mechanism 2 includes a motor 21, a stirring rod 22, and stirring blades 23. The motor 21 is fixedly installed on the upper surface of the recovery tank 1, and its output shaft is vertical. The stirring rod 22 is a round rod structure, and its axis coincides with the axis of the motor 21 output shaft. The stirring rod 22 is fixedly installed at the end of the motor 21 output shaft. Multiple stirring blades 23 are provided and rotatably mounted on the outer wall of the stirring rod 22.

[0032] Multiple rotating grooves 34 are formed through the outer wall of the stirring rod 22. A drive assembly 3 is mounted on the stirring rod 22 to drive the stirring blades 23 to rotate. The drive assembly 3 includes a first bevel gear 31, a rotating rod 32, and a second bevel gear 33. Multiple first bevel gears 31 are arranged in a parallel array on the outer wall of the stirring rod 22 and are fixed to the stirring rod 22. The rotating rod 32 is a cylindrical rod with a horizontal axis. Multiple rotating rods 32 are rotatably mounted within multiple rotating grooves 34, and both ends of the rotating rod 32 are fixed to adjacent stirring blades 23. Multiple second bevel gears 33 are provided and fitted onto both sides of the rotating rod 32. The first bevel gears 31 and second bevel gears 33 mesh with each other, and the second bevel gears 33 are fixed to the rotating rod 32.

[0033] When the staff needs to stir the extracted water and back-extracted material in the recovery tank 1, the staff needs to start the motor 21, which will cause the output shaft of the motor 21 to rotate. This will cause the stirring rod 22 and the stirring blade 23 to rotate under the action of the output shaft of the motor 21, thereby fully stirring the extracted water and back-extracted material. During this process, when the stirring rod 22 rotates, the first bevel gear 31 rotates synchronously with the stirring rod 22, which in turn causes the second bevel gear 33 to rotate under the action of the first bevel gear 31. This causes the rotating rod 32 to rotate under the action of the second bevel gear 33, which in turn causes the stirring blade 23 to rotate under the action of the rotating rod 32, thereby further improving the recovery efficiency.

[0034] An annular groove 4 is provided on the inner wall of the rotating groove 34. An annular block 41 is rotatably disposed in the annular groove 4, and its axis coincides with the axis of the rotating rod 32. The annular block 41 and the rotating rod 32 are fixed to each other.

[0035] When the rotating rod 32 rotates, the annular block 41 rotates synchronously with the rotating rod 32 under the action of the rotating rod 32. During this process, the annular block 41 limits the rotating rod 32, thereby reducing the probability of the rotating rod 32 sliding and thus improving the stability of the device.

[0036] The first gear 5 is fixedly mounted on the outer wall of the output shaft of the motor 21, with its axis coinciding with the axis of the output shaft of the motor 21. The second gear 51 meshes with one side of the first gear 5, with its axis being vertical. The gear ring 52 meshes with the side of the second gear 51 away from the first gear 5, with its axis coinciding with the axis of the first gear 5. The stirring element 53 is fixedly mounted at the lower end of the gear ring 52 and is used to stir the extract water and the back-extracted material.

[0037] When the output shaft of motor 21 rotates, the first gear 5 rotates synchronously with the output shaft of motor 21, which causes the second gear 51 to rotate in the opposite direction under the action of the first gear 5. This causes the gear ring 52 to rotate synchronously in the opposite direction under the action of the second gear 51, thereby causing the stirring element 53 to rotate synchronously in the opposite direction under the action of the gear ring 52. This allows the stirring element 53 to stir the extracted water and the back-extracted material, thereby further improving the recovery efficiency.

[0038] To improve the stability of the device, a blocking ring 6 is fitted onto the outer wall of the stirring rod 22. The blocking ring 6 is rotatably connected to the stirring rod 22. A limiting rod 61 is fixedly installed on the outer wall of the blocking ring 6. The limiting rod 61 is rotatably connected to the second gear 51. A limiting hole with a trapezoidal cross-section (not shown in the figure) is opened on the bottom surface of the second gear 51, and the limiting rod 61 is rotatably connected to the limiting hole. When the stirring rod 22 rotates, the blocking ring 6 and the stirring rod 22 rotate relative to each other. During this process, the blocking ring 6 and the limiting rod 61 limit the second gear 51, thereby reducing the probability of the second gear 51 shaking and improving the stability of the device.

[0039] To improve the stability of the device, a limiting ring 7 is fitted onto the output shaft of motor 21. The limiting ring 7 is rotatably connected to the end of the output shaft of motor 21, and the two ends of the two limiting rings 7 are respectively fixed to the stirring component 53 by limiting members 71. Two baffle plates 8 are fixedly installed at the end of the output shaft of motor 21. The upper and lower surfaces of the two baffle plates 8 abut against the lower and upper surfaces of the limiting rings 7, respectively. The limiting rings 7, limiting members 71, and baffle plates 8 reduce the probability of the gear ring 52 moving up and down, thereby improving the stability of the device.

[0040] The operating principle of the black nylon chip extraction water recovery system in this embodiment is as follows: After the nylon chip raw material has been extracted, the worker puts the extraction water into the recovery tank 1 through the feed pipe 12. Subsequently, the worker puts the back-extracted material into the recovery tank 1 through the feed pipe 12. At this time, the worker stirs the material using the stirring mechanism 2, which improves the recovery efficiency during this process.

[0041] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
