Description

Technical Field

[0001] This invention belongs to the technical field of roller dryers, and particularly relates to an adjustable double roller dryer. Background Technology

[0002] A roller dryer is a continuous drying device that uses rotating circular rollers to dry fluid materials or slurries adhering to the outer wall of the roller through heat conduction. It boasts advantages such as high thermal efficiency, large temperature gradient, and high evaporation intensity of the material film surface, making it particularly suitable for drying high-viscosity slurries or materials containing a high amount of solids. Existing roller dryers use two rollers for extrusion, simultaneously heating the input raw materials to achieve extrusion drying into sheets. The raw materials are extruded and adhere to the outer surface of the rollers. As the rollers rotate, the raw materials come into contact with scraper plates, which then scrape off the dried sheet material. However, different raw materials often require different drying times, and the existing structure cannot adjust the scraper position or time accordingly. Therefore, the existing structure needs to be upgraded to allow for adjustment of both the scraper position and scraper time. Summary of the Invention

[0003] To address the shortcomings of the prior art, the present invention provides an adjustable double-roller dryer that allows for adjustment of the scraping position and scraping time, and offers flexible and convenient operation.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: An adjustable double-roller dryer includes a drying chamber, drying rollers, scrapers, a drive chamber, a circumferential transmission assembly, and a power mechanism. Two drying rollers are installed on opposite sides of the interior of the drying chamber, and a feed trough is formed on the upper side between the two rollers. A scraper abuts against the outer surface of each drying roller. The drive chamber is installed below the drying chamber. The circumferential transmission assembly is mounted on the drive chamber and the drying chamber. The circumferential transmission assembly includes a lifting rod, a lifting disc, an adjusting plate, a rotating sleeve, and a connecting rod. A rotating sleeve is installed at each of the front and rear ends of the drying rollers. An adjusting plate is installed on the inner side of the rotating sleeve; the front and rear ends of the scraper are connected to the outer side of the rotating sleeve via connecting rods; the lifting plate is installed inside the lower part of the drying chamber; the upper side of the lifting plate is fixedly connected to the lower ends of the four adjusting plates, and a lifting rod is installed at the center of the lower side of the lifting plate; the lower end of the lifting rod passes through the center of the lower end of the drying chamber and extends into the drive chamber; the power mechanism is installed in the drive chamber, the power mechanism controls the lifting rod to move up and down, the lifting rod drives the adjusting plate to move up and down, the adjusting plate controls the rotating sleeve to rotate in both directions, and the rotating sleeve drives the scraper to rotate circumferentially on the side of the drying roller.

[0005] Furthermore, the drying roller is provided with a support shaft at the center of its front and rear ends; the outer end of the support shaft is rotatably connected to the inner wall of the drying chamber.

[0006] Furthermore, the rotating sleeve is rotatably engaged with the supporting shaft; the rotating sleeve, the supporting shaft, and the drying roller are distributed along the same axis.

[0007] Furthermore, the power mechanism includes a drive motor, a power screw, a floating block, and a connecting plate; a drive motor is installed on each side of the drive compartment; a connecting plate is installed on each side of the lower end of the lifting rod; a floating block is installed on the outer end of each connecting plate; longitudinal track grooves are opened on both sides of the interior of the drive compartment; a floating block is slidably installed up and down in each longitudinal track groove, and a power screw is rotatably installed longitudinally in the longitudinal track groove, the power screw is threadedly connected to the floating block, and the upper end of the power screw is connected to the drive motor.

[0008] Furthermore, the lower center of the drying chamber is provided with a through-channel, and a sealing sleeve is provided inside the through-channel, with the lifting rod being sealed and inserted into the sealing sleeve.

[0009] Furthermore, the adjusting plate and the rotating sleeve are meshing connection structures of a toothed plate and a gear.

[0010] Furthermore, the scraper has a long strip structure distributed front to back.

[0011] Furthermore, a material distribution pipe is provided at the upper middle of the drying chamber; the material distribution pipe is located directly above the feed trough.

[0012] Furthermore, the feed trough has a V-shaped structure.

[0013] The beneficial effects of this invention are as follows: This invention allows for the control of a lifting rod's up-and-down movement via a power mechanism. The lifting rod, in turn, drives an adjusting plate to move up and down. The adjusting plate controls the forward and reverse rotation of a rotating sleeve. The rotating sleeve, through a connecting rod, drives a scraper to rotate circumferentially on the side of the drying roller. Thus, when the scraper rotates upward and outward on the side of the drying roller, the scraping position and time are extended. Conversely, when the scraper rotates downward and outward on the side of the drying roller, the scraping position and time are shortened. This allows for flexible and convenient changes to the scraping position and time, enabling reasonable adjustments based on the characteristics of different raw materials.
