[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] like Figures 1-2As shown, this utility model provides a technical solution: a tea dehydration device with a quickly replaceable filter screen, including a dehydration tank 1, a dehydration bearing assembly 6, and a hot drying assembly 7. A lifting assembly 2 is installed below the dehydration tank 1, and a drive motor 3 is installed on the upper side of the lifting assembly 2. The lifting assembly 2 includes a lower frame 201 and electric push rods 202. Two electric push rods 202 are symmetrically installed inside the lower frame 201, and the upper side of the electric push rods 202 penetrates the bottom plate of the dehydration tank 1. The lifting assembly 2 also includes a lifting plate 203, and the lifting plate 203 is installed on the top of the electric push rods 202. The lifting plate 203 is located inside the dehydration tank 1. A rotating shaft 4 is provided on the upper side of the 3, and a fixing strip 5 is welded to the side of the rotating shaft 4. A support frame 10 is fixed on the lower outer side of the rotating shaft 4 and the fixing strip 5, and the support frame 10 has a cross-shaped structure. The extension and retraction of the electric push rod 202 facilitates the lifting of the lifting plate 203, thereby driving the drive motor 3 and the dehydration bearing component 6 to lift. The lifting of the rotating shaft 4, the fixing strip 5, and the dehydration bearing component 6 facilitates the removal and replacement of the filter screen 601 and the filter screen frame 602 layer by layer. The drive motor 3 and the rotating shaft 4 facilitate the rotation of the filter screen 601 and the filter screen frame 602, so as to centrifuge and dehydrate the tea leaves inside the filter screen frame 602.

[0024] like Figures 2-4 As shown, a dewatering support assembly 6 is provided on the upper side of the support frame 10. The dewatering support assembly 6 includes a lower filter screen 601, a filter screen frame 602, and a limiting groove 603. The filter screen frame 602 is fixed on the upper side of the lower filter screen 601, and a limiting groove 603 corresponding to the rotating shaft 4 and the fixing strip 5 is opened in the middle of the lower filter screen 601. The dewatering support assembly 6 also includes a side frame 604, a spring 605, and a positioning block 606. The side frame 604 is fixed on both sides of the upper side of the limiting groove 603, and the positioning block 606 is elastically connected to one side of the side frame 604 through the spring 605. The dewatering support assembly 6 also includes a connecting rod 607, and the middle side of the positioning block 606 is fixed. There is a connecting rod 607, which passes through the middle of the side frame 604 and is slidably connected to the side frame 604. The inside of the filter frame 602 is used to place tea leaves. The support frame 10 is used to support the lower filter 601 at the bottom. The shape of the limiting groove 603 in the middle of the lower filter 601 matches the shape of the rotating shaft 4 and the fixing strip 5, so that it can be sleeved on the outside of the two. At this time, the positioning block 606 in the side frame 604 can be tightly attached to the side of the fixing strip 5 under the action of the spring 605 to improve the installation tightness. Conversely, pulling back the connecting rod 607 on the side can drive the positioning block 606 to retract, which facilitates the convenient removal and quick replacement of the lower filter 601 and the filter frame 602.

[0025] like Figure 2 and Figure 5As shown, both sides of the interior of the dehydration tank 1 are equipped with a hot drying assembly 7. The hot drying assembly 7 includes a drying pipe 701 and a jet nozzle 702. The drying pipe 701 is fixed to the two side walls of the dehydration tank 1, and jet nozzles 702 are installed at equal intervals on one side of the drying pipe 701. The hot drying assembly 7 also includes an air supply pipe 703. The air supply pipe 703 is connected to the outside of the drying pipe 701 and penetrates the side wall of the dehydration tank 1. Drainage pipes 8 are connected to both sides of the bottom of the dehydration tank 1. A valve 9 is installed on the lower side of the water pipe 8, and a cover 11 is installed on the upper side of the dehydration tank 1; the air supply pipe 703 is connected to a hot air box, which can send hot air into the interior of the drying pipe 701 so that it can be sprayed out through the evenly distributed air nozzles 702. At this time, the lower filter screen 601, the filter screen frame 602 and the tea leaves inside rotate at a uniform speed, so that the hot air can evenly dry the tea leaves to promote the drying efficiency of the tea leaves. The upper side of the cover 11 is connected to a corresponding exhaust pipe to facilitate timely exhaust and pressure relief.

[0026] In summary, as Figures 1-5 As shown, this tea dehydration device with a quick-change filter screen can be used by first setting the middle limiting groove 603 of the lower filter screen 601 to the outside of the rotating shaft 4 and the fixing strip 5. At this time, the support frame 10 is used to support the lowermost lower filter screen 601. Then, the tea leaves are laid into the filter screen frame 602 of the lower filter screen 601. During this process, the lifting plate 203 can be raised and lowered by the extension and retraction of the electric push rod 202, which can drive the drive motor 3 and the dehydration bearing component 6 to be raised. The raising of the rotating shaft 4, the fixing strip 5, and the dehydration bearing component 6 facilitates the removal and replacement of the lower filter screen 601 and the filter screen frame 602 layer by layer. Then, the lifting plate 203 is lowered, and the lower filter screen 601 and the filter screen frame 602 are rotated by the drive motor 3 and the rotating shaft 4 to facilitate the centrifugal dehydration of the tea leaves inside the filter screen frame 602. At this time, the drain pipe 8 can be used for drainage.

[0027] After centrifugal dehydration, the air supply pipe 703 is connected to a hot air box to send hot air into the drying pipe 701, and then sprayed out through the evenly distributed air nozzles 702. At this time, the lower filter screen 601, the filter screen frame 602 and the tea leaves inside rotate at a uniform speed, so that the hot air can evenly dry the tea leaves to promote the drying efficiency. The upper cover 11 is connected to a corresponding exhaust pipe to facilitate timely exhaust and pressure relief. Finally, after drying is completed, the lifting plate 203 can be raised, and then the side connecting rod 607 can be pulled back to drive the positioning block 606 to retract, which facilitates the easy removal and quick replacement of the lower filter screen 601 and the filter screen frame 602, and also facilitates the removal of the tea leaves. This completes the use process of the tea dehydration device with quick-replaceable filter screen.
