Description

Technical Field

[0001] The utility model relates to the technical field of resin drying, in particular to resin drying equipment. Background Art

[0002] Resin refers to an organic substance with an uncertain but usually high relative molecular weight, which is solid, medium solid, pseudo-solid, or sometimes liquid at room temperature. In a broad sense, it refers to a polymer or prepolymer used as a plastic substrate. Resin has a softening or melting temperature range, tends to flow under the action of external force, and often appears in a shell shape when broken. It is generally insoluble in water but soluble in organic solvents. Resin is a thermosetting polysiloxane with a highly cross-linked structure. Due to its special structure, compared with other organic resins, it has excellent heat resistance, cold resistance, weather resistance, electrical insulation, hydrophobicity, and anti-sticking demoulding properties. Existing resins need to be dried during processing. When the resin is dried, it is placed in a heating container, and then the heating container is heated. This causes uneven heating of the resin near the inside of the heating container, affecting the drying quality. At the same time, the existing drying device does not have a stirring function, has a low drying efficiency, does not have a preheating function, consumes a lot of heating energy, and the hot air after heating is directly discharged, causing waste.

[0003] A Chinese patent discloses a dehydration drying device for resin (publication number CN215638546U). The patent can evenly heat and dry the resin material by setting a drying box, a heating box and a preheating tube, shorten the drying time, reuse the air after the resin is heated, and preheat the raw materials during feeding, thereby saving heating energy consumption. However, when drying the resin material, the patent cannot perform differential drying according to the different sizes and water contents of the resin particles, and secondary screening is required after drying to achieve the screening requirements. Therefore, the utility model provides a resin drying device to solve the above-mentioned problems. Utility Model Content

[0034] The working principle of the utility model is as follows: when the device is needed to dry the resin material, firstly, the first air duct 8 and the second air duct 9 are connected to the air outlet of the external blower, and then a certain amount of resin material is poured into the inner cavity of the first drying box 1 through the feed bin 3, and then the vibrator 5 is driven, and the vibration of the vibrator 5 is transmitted to the frame plate 13 fixedly connected thereto through the vibration connecting rod 15. When the frame plate 13 vibrates, the screen 14 can be driven to vibrate, so that the resin particles of different sizes at the top of the screen 14 can be screened, and the smaller resin particles can be separated. The particles will pass through the screen 14 and enter the bottom of the inner cavity of the first drying box 1 for drying. The larger resin particles will stay at the top of the screen 14. After a certain period of screening, the electric push rod 4 can be driven. The movement of the output end of the electric push rod 4 can drive the second connecting rod 25, the push plate 26 and the connecting plate 30 to move. When the push rod 28 moves to contact the rotating plate 31, the rotating plate 31 will be lifted up, so that the rotating plate 31 rotates. At this time, the larger resin particles can be pushed into the inner cavity of the second drying box 2 for drying through the push plate 26.

[0035] When the frame plate 13 and the screen 14 vibrate, the first spring 17 and the vibration spring 22 will vibrate synchronously, thereby reducing the friction between the frame plate 13 and the inner wall of the first drying box 1 when vibrating, and reducing the vibration amplitude of the first drying box 1, thereby ensuring the stability of the device.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
