DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1 、 2 Figures 3 and 4, the present invention provides a technical solution: a tower cooling device for masterbatch, including: a cooling cylinder 1, the cooling cylinder 1 is a cavity with a cooling sandwich 18 provided in the middle, and a collecting cylinder 5 is fixedly connected to the bottom of the cooling cylinder 1; a reciprocating conveying mechanism is placed inside the cooling cylinder 1, the reciprocating conveying mechanism includes a conveying pipe 6 fixedly connected inside the collecting cylinder 5, a feed port 12 is provided at the bottom of the conveying pipe 6, a transmission pipe 8 for conveying cold air is rotatably connected inside the conveying pipe 6, a spiral blade 7 is fixedly connected to the outside of the transmission pipe 8, and the spiral blade 7 is slidably connected to the inner wall of the conveying pipe 6 for reciprocatingly conveying materials; a cooling part is placed outside the conveying pipe 6, the cooling part includes a cooling water tank 9 fixedly connected to the outside of the conveying pipe 6, a receiving hopper 10 with a stepped inner wall is provided below the cooling water tank 9, the top of the receiving hopper 10 is fixedly connected to the inner wall of the cooling cylinder 1, and heat dissipation fans 11 are equidistantly installed on the outside of the receiving hopper 10.

[0023] It should be noted that in the present invention, cooling water is connected to the cooling sandwich 18 through a joint, so that the cooling water circulates inside the cooling sandwich 18. Then, the masterbatch to be cooled is conveyed into the collecting cylinder 5 through the conveying mechanism. The masterbatch enters the conveying pipe 6 through the feed port 12. The transmission pipe 8 drives the masterbatch to move upward from the bottom inside the conveying pipe 6 through the spiral blade 7. During this period, cold air enters from the bottom of the transmission pipe 8 and blows into the inside of the conveying pipe 6. Under the action of the spiral blade 7, the masterbatch rolls while being conveyed, so that the cold air is in full contact with the masterbatch. When the masterbatch is conveyed out from the top of the conveying pipe 6, it falls outside the cooling water tank 9. The cooling water tank 9 is connected to the cooling sandwich 18, and cooling water is provided inside both of them. The masterbatch slides outside the cooling water tank 9, so that the masterbatch is cooled by the cooling water tank 9 in this way. The cooled masterbatch flows into the receiving hopper 10 and slides downward along the steps inside the receiving hopper 10. During this period, the heat dissipation fans 11 blow air on the masterbatch again for cooling and then the masterbatch falls into the collecting cylinder 5. In this way, the reciprocating cycle cooling of the masterbatch is completed.

[0024] Please refer to Figure 1 、 2As shown in FIGS. 3, a heat dissipation port is provided at the top of the cooling cylinder 1, an exhaust fan 3 is fixedly connected to the outside of the heat dissipation port, a cooling water outlet 17 is fixedly connected to one side of the top of the cooling cylinder 1, and a cooling water inlet 2 is fixedly connected to one side of the bottom of the cooling cylinder 1. Both the cooling water inlet 2 and the cooling water outlet 17 are communicated with the cooling interlayer 18.

[0025] It should be noted that during the cooling process of the masterbatch of the present utility model, a large amount of heat is dissipated, causing the temperature inside the cooling cylinder 1 to rise and fall. At this time, the exhaust fan 3 dissipates the internal heat from the top, preventing the internal temperature from being too high. And the cold water of the cooling water tower is connected to the cooling water inlet 2, and the cooling water outlet 17 is connected to the recovery pipeline. The cooling water enters the cooling interlayer 18 through the cooling water inlet 2, then enters the cooling water tank 9 through the cooling interlayer 18 and the pipeline, spreads from bottom to top, and is discharged through the cooling water outlet 17.

[0026] Please refer to Figure 2 、 3 As shown in FIGS., a plurality of cold air outlets 16 are equidistantly arranged on the outside of the transmission pipe 8. A rotary joint for conveying cold air is installed at the bottom of the transmission pipe 8. A motor 14 is fixedly connected to the bottom of the collecting cylinder 5. The output end of the motor 14 is fixedly connected with a driving gear 15. The outside of the driving gear 15 is meshed with a driven gear 13. The driven gear 13 is fixedly sleeved on the outside of the transmission pipe 8.

[0027] It should be noted that the present utility model connects the external cold air source to the rotary joint. The motor 14 drives the driven gear 13 to rotate through the driving gear 15. The driven gear 13 drives the transmission pipe 8 to rotate. The transmission pipe 8 drives the spiral blade 7 to rotate inside the conveying pipe 6. In this way, the cooperation between the spiral blade 7 and the conveying pipe 6 is used to convey the material. And during the conveying process, the material keeps tumbling under the action of gravity. The cold air blows out from the cold air outlet 16 through the transmission pipe 8, so as to cool the tumbling material, cooling while conveying, and improving the cooling efficiency.

[0028] Please refer to Figure 2 As shown in FIGS., the cooling water tank 9 is a hollow box body with a frustum structure. Both the bottom and the top of the cooling water tank 9 are connected to the cooling interlayer 18 through pipelines.

[0029] It should be noted that the cooling water tank 9 of the present utility model has a frustum structure with a smaller top and a larger bottom, so that its outside is inclined downward. When the masterbatch flows out from the top of the conveying pipe 6 and flows along the outer wall of the cooling water tank 9, the cooling water inside the cooling water tank 9 can absorb its heat, realizing multi-stage cooling.

[0030] Please refer to Figure 1 、 2 As shown in FIGS., a screw conveyor 4 for loading and unloading is provided on one side of the collecting cylinder 5.

[0031] It should be noted that the end of the screw conveyor 4 of the present utility model is provided with a feed inlet and a discharge outlet, which are arranged vertically corresponding to each other, and both the feed inlet and the discharge outlet are provided with detachable sealing plugs. When the rotation direction of the screw shaft of the screw conveyor 4 is clockwise, the screw conveyor blades will push the material into the collecting cylinder 5, that is, forward conveying is realized; when the rotation direction of the screw shaft is counterclockwise, the screw conveyor blades will discharge the material from the collecting cylinder 5.
