Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, in particular to a dryer for down processing. Background Art

[0002] Down has the characteristics of soft texture and good warmth retention, and is often used as filling material for down jackets and down quilts. Due to seasonal and species factors, the quality of down raw materials varies greatly. In order to fully utilize them and improve economic benefits, they must be processed and sorted to remove impurities. After the down raw materials are collected, they generally need to go through processes such as sorting, washing, deodorization and drying.

[0003] In the prior art, the utility model patent with publication number CN213421682U discloses a drying device for down processing. The output shaft of the second motor of the device can drive the first rotating shaft to rotate, thereby driving the stirring rod to rotate. In conjunction with the air nozzle, it prevents the wet down from sticking together, spreads out the down and dries it, thereby improving the drying efficiency.

[0004] However, in actual application, since the down is wet and easy to stick together in the early stage of drying, the effect of stirring the down only by a stirring rod is poor, and the hot air blown out by the air nozzle can only reach the top of the down. The drying efficiency is still poor and needs to be improved. Utility Model Content

[0007] Furthermore, a groove is provided on the front end surface of the outer cylinder, a positioning ring is fixed inside, a mounting hole is provided in the middle of the groove, a bearing is installed on the inner side of the positioning ring and the mounting hole, and the front end of the inner cylinder extends to the outside of the outer cylinder.

[0008] Furthermore, a retaining ring is fixedly connected to the inside of the groove and is sleeved on the outside of the inner cylinder. The front end surface of the retaining ring is flush with the front end surface of the inner cylinder, and a material guide strip is provided at the lower part of the front end of the retaining ring.

[0009] Furthermore, the three side surfaces of the triangular prism are all arc-shaped surfaces, and the air outlets are provided on the two side surfaces that are not in contact with the inner wall of the inner tube.

[0010] Furthermore, the front ends of the multiple triangular prisms are fixed with threaded rods, the blocking cover is provided with mounting holes adapted to the threaded rods, the ends of the threaded rods are threadedly connected with knobs, and a sealing ring is provided on the side of the knob close to the blocking cover and is sleeved on the outside of the threaded rods.

[0012] Furthermore, the diameter of the scraper is equal to the inner diameter of the inner cylinder, and a groove adapted to the triangular prism is provided at the edge of the scraper.

[0013] The advantages of the present invention over the existing technology are that when the inner drum of the present invention rotates, the triangular prisms will be driven to rotate, and the triangular prisms will lift the down to a certain height and then drop it, thereby realizing all-round flipping of the down and avoiding dead corners. By coordinating the rotation of multiple triangular prisms with the inner drum, the contact area between the hot air and the down can be effectively increased, thereby improving the drying efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 4 The figure shows a dryer for down processing, comprising an outer cylinder 1, a supporting leg 2 is provided at the bottom of the outer cylinder 1, an inner cylinder 3 is movably installed inside, a central shaft 4 is passed through and rotatably installed at the rear end of the outer cylinder 1, a through hole is provided in the middle of the central shaft 4, and a driven gear 5 is installed at one end of the outer cylinder 1, a motor 6 is installed at the rear end of the outer cylinder 1, a driving gear 7 is installed on the output shaft of the motor 6, a mounting plate 8 is fixedly connected to the other end of the central shaft 4, and a plurality of positioning columns 9 are connected between the mounting plate 8 and the inner cylinder 3; a groove is provided on the front end surface of the outer cylinder 1, a positioning ring 18 is fixedly connected inside, a mounting hole is provided in the middle of the groove, a bearing sleeved on the outside of the inner cylinder 3 is installed on the inner side of the positioning ring 18 and the mounting hole, the front end of the inner cylinder 3 extends to the outside of the outer cylinder 1, a retaining ring 19 is fixed inside the groove, the front end surface of the retaining ring 19 is flush with the front end surface of the inner cylinder 3, and a material guide strip 20 is provided at the lower front end of the retaining ring 19, an exhaust pipe 16 is provided at the top of the outer cylinder 1, and a drain pipe 17 is provided at the bottom.

[0026] When the drying is completed, stop inputting hot air, remove the knob 22, open the cover 10, and after cooling, slowly pull the scraper 14 outward through the pull rod 15 to pull the down outward through the scraper 14. A collection frame is placed at the front end of the outer tube 1 to collect the down.

[0027] In specific use, the down to be dried is put into the inner drum 3, the baffle 10 is covered and fixed by tightening the knob 22, the motor 6 is turned on and hot air is supplied to the inside of the triangular prism 11, and the triangular prism 11 can lift the down to a certain height and then drop it, thereby realizing all-round turning of the down, avoiding dead corners, and effectively preventing the down from sticking to the inner wall of the inner drum 3 for a long time, thereby improving the drying efficiency; the baffle 10 is opened, and the scraper 14 is slowly pulled outward by the pull rod 15. The scraper 14 can pull the down outward, which is convenient for collecting the down.
