Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing equipment technology, and in particular to a stable mixing device for nylon 6 chips. Background Technology
[0002] In the production of nylon 6 chips, mixing is a crucial step to ensure uniform product quality. Currently, common mixing devices typically employ a mixing tank combined with an agitator to achieve material mixing through mechanical stirring. However, in practical applications, especially for nylon 6 chips with higher density or prone to accumulation, the material at the bottom of the mixing tank can easily accumulate due to gravity, forming "dead zones" and leading to uneven mixing.
[0003] While traditional mixing devices can mix the main materials using agitators, the simple design of the tank bottom and the lack of effective auxiliary fluidization methods make it difficult to fully agitate the bottom flakes, thus affecting the overall mixing effect. Furthermore, some devices attempt to address this issue by increasing the stirring intensity or extending the mixing time, but this not only increases energy consumption but may also lead to a decline in material properties due to excessive shearing.
[0004] Therefore, there is an urgent need for a stable mixing device for nylon 6 chips that can optimize the flowability of nylon 6 chips at the bottom of the mixing tank, improve the mixing uniformity of nylon 6 chips, and at the same time take into account energy efficiency and process stability. Utility Model Content
[0005] The purpose of this invention is to provide a stable mixing device for nylon 6 chips, which can optimize the flowability of nylon 6 chips at the bottom of the mixing tank, improve the mixing uniformity of nylon 6 chips, and at the same time take into account energy efficiency and process stability.
[0006] The present invention adopts the following technical solution:
[0007] A stable mixing device for nylon 6 chips includes a mixing tank, a feeding port at the top of the mixing tank, a guide platform extending upward from the bottom of the mixing tank, and an openable and closable discharge port on one side of the mixing tank of the guide platform; the guide platform is frustum-shaped, and its inner cavity is provided with an air guide pipe connected to an air pump, an air guide nozzle is provided on the air guide pipe, and a through hole for installing the air guide nozzle is provided on the guide platform; a motor-driven mixing paddle is provided inside the mixing tank.
[0008] Preferably, the mixing tank is frustum-shaped; and the guide platform is coaxially arranged with the mixing tank.
[0009] Preferably, the shaft of the mixing paddle is rotatably connected to the top of the guide platform.
[0010] Preferably, a cleaning pusher is provided on the rotating shaft, and the cleaning pusher is in contact with the side wall of the guide platform and the bottom wall of the mixing tank outside the guide platform.
[0011] Preferably, the air guide pipe has a ring structure with multiple layers spaced apart vertically. The bottommost air guide pipe is located at the bottom of the mixing tank, and the air guide nozzle on it is located on the bottom wall of the mixing tank outside the guide platform. The multiple air guide pipes are connected by a conveying pipe, which is connected to the air pump.
[0012] Preferably, except for the bottom air duct, the air nozzles on the other air ducts are arranged at an angle upwards.
[0013] Preferably, the discharge port is located at the bottom of one side of the mixing tank, and a guide cylinder is provided thereon. A sealing plate is slidably provided between the guide cylinder and the mixing tank.
[0014] Preferably, the sealing plate is connected to a cylinder disposed on the side wall of the mixing tank.
[0015] Preferably, the bottom of the feed cylinder is provided with a retractable hose.
[0016] Preferably, the top of the mixing tank is detachably provided with a sealing cover, and the mixing paddle and the motor are mounted on the sealing cover.
[0017] Compared with the prior art, the beneficial effects of this utility model are: This utility model generates forced shear force by rotating the mixing paddle, which can break the agglomeration of nylon 6 chips. The airflow introduced by the air pump through the air pipe forms a turbulent flow field. The two work together to achieve three-dimensional spatial diffusion between solid and solid phases, significantly reducing segregation caused by density differences, thereby achieving the purpose of dynamic mixing and strengthening.
[0018] An air-guiding nozzle injects airflow from the bottom of a frustum-shaped guide platform, causing the sliced particles to fluidize within the mixing tank. Combined with the mechanical stirring of the mixing paddle, this achieves both axial and radial motion of the particles, effectively ensuring uniform mixing. Furthermore, the inclined surface of the guide platform forms an angle with the airflow direction, causing the bottom slices to tumble along the inclined surface, avoiding mixing dead zones caused by gravity deposition and guaranteeing mixing effectiveness. Under this air-motor linkage mechanism, the airflow assistance reduces the torque load on the mixing paddle, lowers motor power consumption, and shortens mixing time. Attached Figure Description

[0022] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:
[0023] like Figures 1 to 3 As shown, the present invention discloses a nylon 6 chip stabilizing mixing device, comprising a mixing tank 1, which is frustoconical in shape. A sealing cover 2 is detachably mounted on the top of the mixing tank 1 by bolts. A feeding port is located on the sealing cover 2, and a cover plate 3 is hinged to the sealing cover 2 to close the feeding port. A guide platform 4 extends upward from the bottom of the mixing tank 1 and is coaxially arranged with the mixing tank 1. A discharge port 5 that can be opened and closed is provided on one side of the mixing tank 1. The guide platform 4 is frustoconical in shape, with a bottom diameter smaller than that of the mixing tank 1. The guide platform 4 has a hollow internal structure with an open bottom. An air guide pipe 6 connected to an air pump is provided inside the guide platform 4. An air guide nozzle 7 is provided on the air guide pipe 6. A through hole for installing the air guide nozzle 7 is provided on the guide platform 4. A motor-driven mixing paddle 8 is provided inside the mixing tank 1. Specifically, the motor is located on the top of the sealing cover 2, and the mixing paddle 8 is located at the bottom of the sealing cover 2. During operation, the forced shearing force generated by the rotation of the mixing paddle 8 can break the agglomeration of nylon 6 chips. The airflow introduced by the air pump through the air pipe 6 forms a turbulent flow field, providing hybrid power for the nylon 6 chips deposited at the bottom of the mixing tank 1, and achieving uniform mixing of the nylon 6 chips at the bottom of the mixing tank 1. Through the synergy of the mixing paddle 8 and the airflow, three-dimensional spatial diffusion between solid and solid phases is achieved, which significantly reduces segregation caused by density differences, thereby achieving the purpose of dynamic mixing enhancement and effectively ensuring the uniformity of nylon 6 chip mixing.
[0024] Furthermore, the shaft of the mixing paddle 8 is rotatably connected to the top of the guide platform 4 via a bearing, which provides support for the bottom of the mixing paddle 8 and ensures the stability of the mixing paddle 8 during operation. A cleaning push plate 9 is also provided on the shaft. The cleaning push plate 9 is arranged obliquely along the side wall of the guide platform 4 and extends towards the inner wall of the mixing tank 1 at its bottom. The cleaning push plate 9 is in active contact with the side wall of the guide platform 4 and the bottom wall of the mixing tank 1 outside the guide platform 4. During operation, the cleaning push plate 9 can further enhance the disturbance of the nylon 6 chips deposited at the bottom of the mixing tank 1, improve the uniformity of its mixing, and in the later stage of discharge, the rotation of the mixing paddle 8 drives the cleaning push plate 9 to push the nylon 6 chips deposited at the bottom of the mixing tank 1 towards the discharge port 5, which facilitates the smooth discharge of the nylon 6 chips.
[0025] In this embodiment, the discharge port 5 is located at the bottom of one side of the mixing tank 1, and a guide cylinder 10 is provided on it. A sealing plate 11 is slidably arranged between the guide cylinder 10 and the mixing tank 1. A sliding opening is provided on one side of the guide cylinder 10 along the length direction of the discharge port 5, and the sealing plate 11 opens and closes the discharge port 5 through the sliding opening. Preferably, the sealing plate 11 is connected to a cylinder 13 provided on the side wall of the mixing tank 1, which can realize the automatic opening and closing of the sealing plate 11, improving the convenience of operation. In addition, a retractable hose is provided at the bottom of the guide cylinder 10 so as to extend the length of the guide cylinder 10 as needed to meet different discharge requirements.
[0026] Furthermore, in this embodiment, the air guide pipe 6 has a ring structure with multiple layers spaced vertically. The bottommost air guide pipe 6 is located at the bottom of the mixing tank 1, with the air guide nozzle 7 vertically positioned on the bottom wall of the mixing tank 1, outside the guide platform 4. The air guide nozzle 7 does not protrude from the bottom wall of the mixing tank 1 to avoid affecting the movement of the cleaning push plate 9. The air guide pipes 6 outside the bottommost layer are arranged in the cavity within the guide platform 4. The air guide pipes 6 are preferably made of high-strength metal material to ensure air delivery while providing support for the guide platform 4 and preventing deformation due to external forces. Multiple air guide pipes 6 are connected by a conveying pipe 12, which is connected to an air pump. In addition, except for the bottommost air guide pipe 6, the air guide nozzles 7 on the other air guide pipes 6 are all arranged at an upward angle, and the through holes on the guide platform 4 match the angle of inclination of the air guide nozzles 7. This arrangement can expand the disturbance area of the nylon 6 chips through the upward airflow, thereby improving the mixing effect.
[0027] In use, after adding material through the feeding port at the top of the sealing cover 2, the cover plate 3 is closed. Then, the motor is turned on to drive the mixing paddle 8 to rotate, completing the mixing of nylon 6 chips. At the same time, depending on the state of different batches of nylon 6 chips, the air pump can be turned on periodically or continuously to deliver airflow into the mixing tank 1, thereby increasing the disturbance of the nylon 6 chips at the bottom of the mixing tank 1 and improving the mixing effect. After mixing is completed, the sealing plate 11 at the discharge port 5 is opened to discharge the material.
