Description

Technical Field

[0001] This utility model belongs to the field of plastic woven bag processing technology, specifically relating to a drying and mixing device for woven bag raw materials. Background Technology

[0002] Plastic woven bags are packaging products made primarily from resins such as polyethylene, polypropylene, or polyester. The process involves extruding a film, cutting and stretching it into flat filaments, then weaving the filaments into a bag body and sewing it together. Their structure can be categorized into single-layer, multi-layer, coated, and laminated types. They possess tensile strength and abrasion resistance, and are widely used in the packaging of agricultural and sideline products, chemical raw materials, building materials, and logistics transportation for containing, protecting, and transporting various goods.

[0003] To obtain higher quality finished plastic woven bags, the raw materials need to be dried and stirred before processing. This involves high-temperature evaporation of moisture from the raw materials. For example, a drying and stirring device for woven bag raw materials, as described in announcement number CN222590365U, solves the problem of low heat conduction efficiency and significant heat loss in traditional drying mixers, which hinder efficient heating of the raw materials. However, this solution still allows most of the heat to escape into the air, resulting in higher energy consumption. Furthermore, this solution suffers from uneven heating; the raw material temperature near the exhaust port is higher, and the stirring process only allows horizontal stirring, preventing the material near the inner wall of the container from being heated.

[0021] As a preferred embodiment, the stirring structure further includes: a shaft support 9, a stirring shaft 10, and a stirring motor 11; the shaft support 9 is installed on the inner wall of the heat exchange tank 7, the stirring shaft 10 is installed on the inner wall of the shaft support 9 and the heat insulation pipe 8 through bearings, and the stirring motor 11 is installed on the lower wall of the heat insulation tank 4 through a motor frame, and the drive end of the stirring motor 11 is connected to the stirring shaft 10.

[0022] As a preferred embodiment, the sealing structure further includes: a sealing cover 12 and a vent pipe 13; the sealing cover 12 is installed on the upper wall of the heat insulation tank 4, and the sealing cover 12 and the heat insulation tank 4 are fixed by bolts and nuts; the upper wall of the sealing cover 12 has a through hole, the vent pipe 13 is installed in the through hole of the sealing cover 12, a temperature sensor 16 is installed on the lower wall of the sealing cover 12, and a humidity sensor 17 is installed on the lower wall of the sealing cover 12.

[0023] Working principle:

[0024] I. Preparations before use: The operator first connects the external AC power supply to this utility model to provide energy to the electrical appliance, and connects the matching controller to the electrical appliance to provide control and operating logic. The operator places the prepared woven bag raw materials inside the heat spreader 7, and at the same time installs the sealing cover 12 on the upper wall of the heat insulation tank 4, and fixes the heat insulation tank 4 and the sealing cover 12 with bolts and nuts. It should be noted that thermally conductive silicone grease is filled between the heat insulation tank 4 and the heat spreader 7, which allows the heat generated by the eight heating rods 5 and the heating element 6 to be evenly transferred into the heat spreader 7.

[0025] II. Drying and Stirring: Upon starting the device, the stirring motor 11 drives the stirring shaft 10 to rotate. A spiral blade is mounted on the outside of the stirring shaft 10. The rotation of the shaft causes the spiral blade to rotate, continuously tumbling the woven bag material at the bottom to the top. The material at the top falls back to the bottom under gravity, creating a circulation. Simultaneously, eight heating rods 5 and heating plates 6 begin heating. The generated heat is transferred to the heat spreader 7 via thermal grease, raising the overall temperature of the heat spreader 7. The heat does not dissipate from the insulated tank 4, and the accumulated heat causes the internal temperature of the heat spreader 7 to continuously rise. This increased temperature heats the material, causing the moisture to evaporate and be discharged into the atmosphere through the vent pipe 13. Temperature sensor 16 and humidity sensor 17 continuously monitor the internal temperature and humidity. When the temperature is about to reach the set upper threshold, the eight heating rods 5 and heating elements 6 stop heating. When the temperature is about to reach the set lower threshold, the eight heating rods 5 and heating elements 6 start heating. When the humidity reaches the standard, the invention stops working, completing the drying and stirring of the raw materials.

[0026] 3. Raw material discharge: After drying and stirring are completed, the operator removes the sealed cover 12 and removes the two stirring fixing bolts 14 by rotating them. The operator holds the handle 15 and rotates the heat insulation tank 4 around the two heat insulation support shafts 3 until the raw material is discharged from the heat homogenizing tank 7.
