Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and in particular to a disc dryer that is easy to feed. Background Technology

[0002] The disc dryer is a highly efficient, energy-saving, and widely used conductive continuous drying equipment. Its core principle is to achieve efficient drying through direct heat exchange between the hollow drying disc and the material.

[0003] Traditional disc dryers mostly use a single vertical pipe feeding method. Wet materials fall directly into the center area of ​​the drying disc through the feeding pipe. As the drying disc rotates, it is easy for them to accumulate in the center of the drying disc, resulting in uneven material distribution and forming a pile-like mass, which affects subsequent drying. At the same time, different wet materials have different properties. Some materials with poor flowability will accumulate at the pipe inlet, affecting the flow inside the pipe and affecting the feeding efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a disc dryer that facilitates material feeding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A vibrating plate is installed on the side away from the conical disc with protrusions.

[0007] The vibrating plate is installed on one side of the inclined discharge port at the bottom of the straight cylinder. A connecting rod is installed on the bottom side of the vibrating plate. The other end of the connecting rod contacts the outer wall of the cone-shaped disk with protrusions, and a torsion spring is installed at the rotational connection between the vibrating plate and the inclined discharge port.

[0008] Furthermore, a preferred structure is that the straight cylinder communicates with the interior of the machine body.

[0009] Furthermore, in a preferred configuration, a feed inlet is provided on one side of the upper part of the conical feed cylinder.

[0010] In addition, in a preferred configuration, the drive motor is installed in the middle of the conical feed cylinder, the output end of the drive motor extends into the inside of the conical feed cylinder and is fixedly connected to the drive shaft, and the operation of the drive motor drives the drive shaft to achieve rotational motion.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 A disc dryer for easy feeding includes a body 1. A conical feed cylinder 2 is installed on one side of the upper part of the body 1 through a straight cylinder 22. A drive shaft 31 is installed at the center of the inside of the conical feed cylinder 2. The drive shaft 31 is driven by a drive motor 3. A stirring frame 32 is installed on the upper part of the drive shaft 31, a spiral blade 33 is installed in the middle part, and the bottom is connected to a connecting support rod 34 and extends out of the straight cylinder 22 and is equipped with a conical disc 35 with protrusions. A vibrating plate 4 is installed on the side away from the conical disc 35 with protrusions.

[0025] The vibrating plate 4 is installed on one side of the inclined discharge port 5 at the bottom of the straight cylinder 22. A connecting rod 41 is installed on the bottom side of the vibrating plate 4. The other end of the connecting rod 41 contacts the outer wall of the cone-shaped disk 35 with protrusions. A torsion spring 42 is installed at the rotating connection between the vibrating plate 4 and the inclined discharge port 5. When the vibrating plate 4 rotates, the torsion spring 42 deforms and generates torsional force, which drives the vibrating plate 4 to reset and rotate.

[0026] The straight cylinder 22 connects to the interior of the machine body 1.

[0027] A feed inlet 21 is provided on one side of the upper part of the conical feed cylinder 2.

[0028] The drive motor 3 is installed in the middle of the conical feed cylinder 2. The output end of the drive motor 3 extends into the inside of the conical feed cylinder 2 and is fixedly connected to the drive shaft 31. The drive motor 3 drives the drive shaft 31 to achieve rotational movement.

[0029] A spiral blade 33 is installed at the center of the inside of the straight cylinder 22. The spiral blade 33 has the effect of squeezing and conveying the material, increasing the material flowability inside the straight cylinder 22.

[0030] A stirring rack 32 is installed at the center of the conical feed cylinder 2. The stirring rack 43 improves the flowability of the material inside the conical feed cylinder 2.

[0031] A connecting rod 34 is fixedly connected to the bottom end of the drive shaft 31. The connecting rod 34 passes through the inclined discharge port 5 and extends out of the bottom of the straight cylinder 22. A conical disc 35 with protrusions is fixedly installed at the bottom end of the connecting rod 34. Multiple protrusions are arranged in a ring array on the outer wall of the conical disc 35 with protrusions.

[0032] An arc-shaped rubber strip 43 is connected to one side of the inclined discharge port 5, and the other side of the arc-shaped rubber strip 43 is connected to the upper wall of the vibrating plate 4. The arc-shaped rubber strip 43 covers the rotation axis of the vibrating plate 4, which can effectively prevent the material from entering the rotation gap of the vibrating plate 4. Moreover, through the elasticity of the rubber material, it can effectively adapt to the vibration requirements of the vibrating plate 4.

[0033] In this embodiment, wet material enters the conical feed cylinder 2 through the feed inlet 21. The drive motor 3 drives the drive shaft 31 to rotate. The stirring rack 32 located inside the conical feed cylinder 2 stirs the wet material to improve its fluidity. Then, the wet material is introduced into the straight cylinder 22 through the conical structure and extruded and conveyed to the inclined discharge port 5 by the spiral blades 33. The outlet cross section of the inclined discharge port 5 is rectangular, so that the material can fall evenly in a long strip shape. At the same time, a vibrating plate 4 is provided on one side of the inclined discharge port 5. The vibrating plate 4 vibrates in linkage with the rotation of the drive shaft 31. The high-frequency vibration is used to assist the material feeding function, avoid material accumulation, and speed up the flow and feeding.

[0034] The drive shaft 31 rotates synchronously with the connecting rod 34. When the connecting rod 34 rotates, it drives the cone-shaped disk 35 with protrusions to rotate. The cone-shaped disk 35 with protrusions is located below the straight cylinder 22 and is in contact with the connecting rod 41 on one side of the vibrating plate 4. As the cone-shaped disk 35 with protrusions rotates, the multiple protrusions on its outer wall will intermittently contact the connecting rod 41. The connecting rod 41 is squeezed and rotates, causing the vibrating plate 4 to deflect as a whole. Due to the setting of the torsion spring 42, a torsional force is generated after the vibrating plate 4 rotates to drive the vibrating plate 4 to quickly return to its original position. This process is repeated to achieve high-frequency motion of the vibrating plate 4.

[0035] As the vibrating plate 4 vibrates, the arc-shaped rubber strip 43 installed on the vibrating plate 4 will deform with the vibration.

[0036] A seal is provided at the connection between the connecting rod 34 and the straight cylinder 22 to ensure sealing performance. Using a seal to ensure the normal operation of the equipment is a routine operation in this field and will not be explained further.

[0037] The machine body 1, namely the disc dryer, has a straight cylinder 22 that introduces the material into the drying disc at the top of the disc dryer to complete the feeding. The conical feed cylinder 2, vibrating plate 4 and other components enable the easy feeding of the disc desiccant.

[0038] The specific details of the drying process of the disc dryer not explained in detail above are common knowledge to those skilled in the art.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
