Description

Technical Field

[0001] This utility model relates to the technical field of sheath material processing equipment, specifically a vacuum negative pressure drying and cooling device for sheath materials. Background Technology

[0002] Sheathing material is a special plastic material used for the outer protection (sheath) of cables and wires, mainly serving functions such as mechanical protection, insulation, and weather resistance. The processing and production of sheathing material involves multiple steps, including batching and metering, kneading, refining, plasticizing, sheeting, pelletizing, extrusion, and packaging. The extruded sheathing material can reach heights of 130-150°C, which is inconvenient for subsequent processes, therefore cooling treatment is necessary.

[0003] In existing methods of processing sheathing materials, the sheathing materials are dried and cooled by standing in a static manner. This may cause the sheathing materials to stick together during the drying process, which will affect the subsequent use of the cooled sheathing materials.

[0004] A search revealed that in the prior art, publication number CN219446076U discloses a polyethylene sheath material cooling device, including a frame. Multiple feed pipes are fixedly installed on one side of the frame, extending through one side of the frame and into the frame. Multiple discharge pipes are fixedly installed on the other side of the frame, extending through the other side of the frame and into the frame. A limiting pipe is fixedly connected to one side of the feed pipes, and one side of the limiting pipe is fixedly connected to one side of the discharge pipes. The limiting pipe is mesh-like. The beneficial effects of this invention are: through the spraying assembly, water is transported through the inlet pipe to the inside of the circular frame by a booster pump, and then through the circular frame, connecting frame, vertical pipe, and connecting frame, the water is atomized and sprayed onto the extruded polyethylene sheath through an atomizing nozzle. This allows the polyethylene sheath to cool down quickly and maintain its post-molding state. Simultaneously, a gear causes a circular toothed plate to rotate, driving the parts connected to the atomizing nozzle.

[0005] However, the aforementioned patent involves using a static method to dry and cool the sheathing material in a pile during the drying and cooling process. This may cause the sheathing material to stick together during the drying process, thus affecting the subsequent use of the cooled sheathing material. Therefore, a vacuum negative pressure drying and cooling device for sheathing material is proposed. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5 This utility model provides a technical solution:

[0032] It includes an outer shell 1, a drying mechanism 3 and a cooling mechanism 4. The drying mechanism 3 is located above the cooling mechanism 4 and is connected to the cooling mechanism 4 through a connecting pipe 6.

[0033] The drying mechanism 3 includes a drying chamber 7, a vacuum pump 23, and a stirring assembly for stirring the sheathing material inside the drying chamber 7. The drying chamber 7 is located on the inner top surface of the outer shell 1, and the vacuum pump 23 is located on the top of the outer shell 1 and is connected to the interior of the drying chamber 7.

[0034] It also includes a receiving mechanism 5 for collecting the dried and cooled sheathing material.

[0035] The stirring assembly includes a rotary motor 8 and a stirring rod 9. The rotary motor 8 is fixedly installed on the outer side wall of the outer shell 1. The stirring rod 9 is rotated inside the drying oven 7. One end of the stirring rod 9 passes through the drying oven 7 and the side wall of the outer shell 1 and is keyed to the output shaft of the rotary motor 8.

[0036] A retractable partition 12 is provided below the stirring rod 9.

[0037] A slot 10 is provided on the side wall of the drying oven 7 away from the rotating motor 8. A partition 12 is inserted into the slot 10. The outer side wall of the partition 12 inside the drying oven 7 is provided with a protrusion 13. A telescopic rod 11 is provided on the side wall of the drying oven 7 above the slot 10. The telescopic rod 11 adopts the JGA25 series. The working end of the telescopic rod 11 is fixedly installed with the partition 12. A packing tube 24 is provided through the top of the drying oven 7. The protrusion 13 is slidably disposed inside the slot 10, and the side wall where the protrusion 13 contacts the slot 10 is provided with a sealing strip.

[0038] Sheathing material is added to the inside of the drying chamber 7 through the packing tube 24, and then the port of the packing tube 24 is sealed by the sealing plug. At this time, the partition 12 is located inside the drying chamber 7. Since the outer end of the partition 12 is provided with protrusions 13, the protrusions 13 are connected to the inner wall of the slot 10 opened inside the drying chamber 7. The rotating motor 8 adopts the Panasonic MINASA6 series. The rotating motor 8 is started to drive the stirring rod 9 to rotate inside the drying chamber 7, so that the stirring rod 9 stirs the sheathing material particles on the surface of the partition 12. The vacuum pump 23, which is connected to the inside of the drying chamber 7 above the outer shell 1, performs vacuuming on the inside of the drying chamber 7 to dry the sheathing material inside and evaporate its internal moisture.

[0039] After evaporation is complete, the expansion rod 11 is activated to move the partition 12 to the outside of the drying chamber 7. The dried sheath material on the surface of the partition 12 falls into the inside of the connecting pipe 6 and enters the cooling mechanism 4 below through the connecting pipe 6 for cooling and preservation.

[0040] The cooling mechanism 4 includes a cooling pipe 14, a water inlet pipe 17, and a discharge pipe 18. The cooling pipe 14 is located below the drying chamber 7 and is connected to the drying chamber 7 through a connecting pipe 6. A fixing sleeve 15 is fixedly sleeved on the outer arc surface of the cooling pipe 14. The fixing sleeve 15 is fixedly installed on the inner bottom surface of the outer shell 1. One end of the cooling pipe 14 is connected to the water inlet pipe 17 through the outer shell 1, and the other end of the cooling pipe 14 is connected to the discharge pipe 18 through the outer shell 1.

[0041] The cooling mechanism 4 also includes a drive motor 16 and an auger 19. The drive motor 16 is bolted to the side wall of the housing 1 above the discharge pipe 18. The auger 19 is rotatably disposed inside the cooling pipe 14. One end of the auger 19 passes through the cooling pipe 14 and is keyed to the output shaft of the housing 1 and the drive motor 16.

[0042] The discharge pipe 18 is located above the receiving mechanism 5, which is located below the side wall of the outer casing 1.

[0043] A water inlet pipe 17 is installed through one end of the cooling pipe 14, and a discharge pipe 18 is installed through the other end of the cooling pipe 14. Cooling water is injected into the cooling pipe 14 through the water inlet pipe 17. Since the surface temperature of the dried sheath material is too high to be preserved, the sheath material is cooled by entering the cooling pipe 14 through the connecting pipe 6. At the same time, the cooling pipe 14 is also equipped with an auger 19 driven by a drive motor 16. The drive motor 16 is a Panasonic MINASA6 series. The auger 19 drives the sheath material inside the cooling pipe 14 to be conveyed and moved. The material is dropped into the collection mechanism 5 through the discharge pipe 18 and collected by the collection mechanism 5.

[0044] The receiving mechanism 5 includes a receiving box 21 and a filter box 22. The receiving box 21 is located on the side wall of the outer shell 1 below the discharge pipe 18. The receiving box 21 is equipped with a removable filter box 22. The receiving box 21 is located on the side wall of the bottom support leg of the drying oven 7.
