Description

Technical Field

[0001] The utility model relates to the technical field of disc dryers, in particular to a disc dryer with uniform feeding. Background Art

[0002] Wet material is continuously fed from the feeder onto the first drying plate of the dryer. The rake arm with rakes rotates, causing the rakes to continuously flip the material. The material flows along an exponential spiral across the surface of the drying plate. Any material on the small drying plate moves to the outer edge and falls onto the outer edge of the larger drying plate below. The material on the larger drying plate then moves inward and falls from the center onto the next smaller drying plate. The large and small drying plates are alternately arranged up and down, allowing material to flow continuously throughout the dryer. The main unit's drying heating plate is fed with hot water, which enters at one end and exits at the other.

[0003] The dried material falls from the last drying plate to the bottom layer of the shell, where it is finally moved by rakes to the material outlet for discharge. Fin heaters are installed to introduce a small flow of hot air into the dryer to absorb moisture escaping from the material during the drying process, preventing condensation on the top of the dryer and in the exhaust pipe. A bag dust collector is also installed to capture trace amounts of particularly fine and light materials entrained in the exhaust gas, thereby protecting the environment and reducing product loss.

[0004] However, the current disc dryer generally feeds directly vertically. Since the material is wet, the material entering the first drying disc is poorly dispersed and accumulates, which makes the rake's material distribution and conveying effect poor, affecting the drying and feeding efficiency.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] See also Figures 1 to 5 In the utility model, a disc dryer with uniform feeding comprises a tank body 1, a feed hopper 2 is fixedly mounted on the top of the tank body 1, the bottom end of the feed hopper 2 is rectangular, a material distribution mechanism 3 is mounted on the feed hopper 2, the material distribution mechanism 3 cooperates with the bottom of the feed hopper 2, a driving motor 4 is mounted on the bottom of the tank body 1, the output end of the driving motor 4 is fixedly connected to a transmission rod 5 through a coupling, the top end of the transmission rod 5 extends to the inside of the tank body 1, and the top end of the transmission rod 5 is connected to the inside of the tank body 1 for rotation. Then, the inside of the tank body 1 is vertically installed with overlapping hollow small material trays 6 and large material trays 7, and the outer side of the transmission rod 5 is fixedly connected to multiple groups of multi-group material rake rods 11 that cooperate with the small material tray 6 and the large material tray 7, and the outer side of the transmission rod 5 is rotatably connected to the inner side of the small material tray 6. The inner side of the large material tray 7 is provided with a central hole 8 for discharging material, and the transmission rod 5 is located inside the central hole 8. The inside of the tank body 1 is installed with a heat source inlet pipe 9 and a heat source outlet pipe 10 that are connected to the inside of the small material tray 6 and the large material tray 7.

[0024] In the present invention, the tank body 1 is used as the main body of the device. When in use, the material is first fed through the feed hopper 2, and the material balancing mechanism 3 and the drive motor 4 are started synchronously. The material balancing mechanism 3 blocks the bottom opening of the feed hopper 2, and the material entering the feed hopper 2 needs to be evenly and continuously dispensed by the material balancing mechanism 3, so that it falls onto the first small material tray 6 at the top, and the drive motor 4 drives the transmission rod 5 to rotate to drive the rake rod 11 to spirally push the material falling on the small material tray 6, so that it falls onto the large material tray 7, and under the action of the rake rod 11, the material is spirally pushed inward to make it move toward the center. The heat is then directed outwards through the heat source outlet pipe 10 so as to achieve high-temperature drying. This allows the device to have more uniform feeding, effectively avoid feed blockage, and improve drying and feeding efficiency. This solves the problem that the feed of the disc dryer in the prior art is generally vertical direct feeding, and since the material is wet, the dispersion effect of the material entering the first drying disc is poor, and accumulation will occur, which makes the rake's material distribution and conveying effect poor, affecting the drying and feeding efficiency.

[0025] See also Figure 2 and Figure 5 , wherein: the material balancing mechanism 3 includes a servo motor 31, a transmission member 32, a material shifting rod 33 and a positioning block 34. The servo motor 31 is fixedly installed on the top of the tank body 1. The output end of the servo motor 31 extends into the interior of the tank body 1 and is connected to the transmission member 32. One end of the material shifting rod 33 is rotatably connected to the positioning block 34. The top of the positioning block 34 is installed on the inner wall of the tank body 1. The other end of the material shifting rod 33 is connected to the transmission member 32.

[0026] In the present invention, the servo motor 31 is started to drive the transmission member 32 to operate, thereby driving the material-discharging rod 33 to rotate. The material-discharging rod 33 rotates at the rectangular discharge port at the bottom of the feed hopper 2 to achieve uniform and continuous discharge, thereby preventing the material from falling and accumulating at one time.

[0027] See also Figure 2 , wherein: the transmission member 32 includes a rotating rod 321, a horizontal bevel gear 322 and a vertical bevel gear 323, the output end of the servo motor 31 is fixedly connected to the rotating rod 321 through a coupling, the bottom end of the rotating rod 321 is fixedly connected to the horizontal bevel gear 322, one side of the vertical bevel gear 323 is fixedly connected to the material tapping rod 33, and the outer side of the horizontal bevel gear 322 is meshed with the outer side of the vertical bevel gear 323.

[0028] In the present invention, the servo motor 31 drives the rotating rod 321 to rotate, thereby driving the horizontal bevel gear 322 to rotate, thereby driving the vertical bevel gear 323 to rotate, thereby driving the material-discharging rod 33 to rotate, thereby achieving uniform and continuous material discharging.

[0029] See also Figure 2 and Figure 5 , wherein: an inner groove 331 is opened on the outer side of the material shifting rod 33, and an annular material shifting strip 332 is fixedly connected to the inside of the inner groove 331.

[0030] In the present invention, by rotating the material stripping strips 332 inside the inner groove 331 and utilizing the intervals between the material stripping strips 332 , the material stripping strips 332 can continuously and quantitatively output the material and deliver it to the first small material tray 6 .

[0031] See also Figure 1 and Figure 4 , wherein: the outer edge of the large material tray 7 is provided with an inner inclined convex edge 71.

[0032] In the present invention, the material falling from the outside of the small material tray 6 is blocked by the inner inclined convex edge 71 on the large material tray 7, preventing the material from scattering and falling directly to the bottom.

[0033] See also Figure 3 , wherein: the top cross-sections of the heat source inlet pipe 9 and the heat source outlet pipe 10 are both double-channel inlet and outlet.

[0034] In the present invention, a more efficient and stable heat source introduction and export is achieved through the dual-channel heat source inlet pipe 9 and the heat source outlet pipe 10, thereby improving heating uniformity.

[0035] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
