[0020] 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.

[0021] Please see Figures 1-3The present invention discloses a vacuum belt drying device with an internal baffle, comprising a drying equipment body 1, a feed inlet at the front end of the drying equipment body 1, a discharge outlet at the rear end of the drying equipment body 1, a conveyor belt 8 inside the drying equipment body 1, a top plate 7 located on one side of the feed inlet at the upper end of the drying equipment body 1, a bottom plate 9 located above the conveyor belt 8 inside the drying equipment body 1, a material-dispensing baffle 10 at the front end of the bottom plate 9, a lifting assembly 12 at the top end of the material-dispensing baffle 10, a scraper rod 13 located at the front end of the material-dispensing baffle 10 and in contact with the surface of the material-dispensing baffle 10 at the output end of the lifting assembly 12, a threaded rod 11 rotatably disposed at the upper end of the bottom plate 9 and penetrating the top plate 7, the threaded rod 11 being threadedly connected to the top plate 7, and support rods 15 penetrating the top plate 7 at both ends of the bottom plate 9.

[0022] The top plate 7 is fixed to the upper end of the drying equipment body 1 by screws.

[0023] The feeding hopper 2 and the feeding box 3 are integrated structures, the feeding baffle 10 and the bottom plate 9 are integrated structures, the lifting assembly 12 adopts a magnetic coupling cylinder, and the motor 4 adopts a servo motor.

[0024] This vacuum belt dryer with internal baffles achieves uniform drying of materials through the coordinated operation of multiple components.

[0025] The upper end of the feed inlet is provided with a feed box 3, the upper end of the feed box 3 is provided with a discharge hopper 2, the inside of the feed box 3 is provided with a cylindrical block 5, the two ends of the cylindrical block 5 are rotatably connected to the feed box 3, a motor 4 is provided on one side of the feed box 3, the output end of the motor 4 is connected to one end of the cylindrical block 5, and the circumference of the cylindrical block 5 is provided with multiple discharge slots 6 of the same size.

[0026] Material enters the feed box 3 from the discharge hopper 2. The servo motor drives the cylindrical block 5 to rotate, and the discharge troughs 6 around the cylindrical block 5 uniformly receive and release the material, allowing it to initially spread on the conveyor belt 8. Rotating the threaded rod 11, through its threaded engagement with the top plate 7, raises and lowers the bottom plate 9. The material-pushing baffle 10 at the front end of the bottom plate 9 adjusts its height accordingly, thereby controlling the thickness of the material spread on the conveyor belt 8. As the conveyor belt 8 moves the material forward, the material-pushing baffle 10 guides and separates any accumulated material, preventing it from concentrating.

[0027] At the same time, the magnetic coupling cylinder, as the lifting component 12, drives the scraper 13 to move up and down intermittently along the surface of the feeding baffle 10, so as to remove the material adhering to the baffle in time and prevent the material from accumulating and affecting the feeding effect.

[0028] The top plate 7 has two annular seats 14 on its symmetrical threaded rod 11 at the upper end, and the annular seats 14 are provided with sealing rings that are penetrated by the support rod 15.

[0029] The support rod 15 passes through the top plate 7 and engages with the sealing ring on the annular seat 14 to ensure the stability of the bottom plate 9 during lifting and lowering and the sealing of the device. In a vacuum environment, the conveyor belt 8 drives the material through the drying equipment body 1 to achieve uniform drying, and the dried material is discharged from the outlet.

[0030] Material of hopper 2: 304 stainless steel;

[0031] Material of feed box 3: 304 stainless steel;

[0032] Material of material for material feeding baffle 10: 304 stainless steel (5mm thick), surface treatment: Teflon coating (non-stick, coefficient of friction ≤0.1);

[0033] Magnetic coupling cylinder model: SMCVEX2 series, working pressure: 0.4-0.6MPa (external air source), vacuum adaptability: applicable vacuum degree ≤10Pa.

[0034] In addition, the device has a reasonable structural design, with all components working together and easy operation. By optimizing the material feeding, spreading, and material distribution processes, it significantly improves the drying uniformity and efficiency of the vacuum belt dryer, reduces the risk of equipment failure due to material accumulation, and has high practical value and economic benefits.
