Description

Technical Field

[0001] The utility model relates to the field of ceramic production, in particular to a material drying device for producing high-purity alumina ceramics. Background Art

[0002] Alumina needs to be dried before being made into ceramics to reduce the water content of alumina and avoid quality problems in the final ceramic products. The drying devices currently used generally heat the interior of a space at one end of a space, thereby heating the material. However, the heat source of this method is relatively concentrated. When the equipment is long or the space is large, it is easy for some materials to not fully contact the heat source, resulting in uneven material drying. At the same time, the drying device is mostly placed horizontally. This method can easily cause part of the material to be entrained when the material is moved through its own rotation, which can easily lead to less contact with the heat source and incomplete evaporation of water. Therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be solved. Utility Model Content

At the same time, the material can be fully moved in the drying chamber 2, so that the material is fully exposed to the heat source so that it is heated evenly, avoiding the occurrence of uneven drying. In this embodiment, it mainly includes an equipment rack 1. The equipment rack 1 is a C-shaped structure, and a feed port 7 is fixedly provided on the bottom side of the equipment rack 1.

A control module is also provided.

[0025] In order to achieve the drying of materials, ensure that the materials are heated evenly. Figure 3In this embodiment, a drying chamber 3 is fixedly provided inside the drying cabin 2. The drying chamber 3 is a hollow annular structure, and an annular baffle 10 is fixedly provided at the bottom end of the drying chamber 3, which is designed in the same shape as the bottom end of the drying cabin 2 and is coaxially arranged.

A spiral partition 11 is provided inside the drying chamber 3, and the upper and lower parts of the drying chamber 3 are connected by a vent 12 that runs through the drying chamber 3 and the drying cabin 2. Hot air is supplied through the vent 12 provided at the lower part of the drying chamber 3, and discharged through the vent 12 at the upper part, so that the material in the drying cabin 2 is heated. In this process, the drying chamber 3 is fully heated through the partition 11, so that the material in the drying cabin 2 is heated evenly.

[0026] A first spiral auger 13 coaxial with the drying chamber 2 is rotatably arranged on the equipment frame 1 at the bottom of the drying chamber 2. The first spiral auger 13 passes through the inner ring of the drying chamber 3 and the material discharge port 9, and its top passes through the top of the equipment frame 1. The spiral part of the first spiral auger 13 is arranged in a contour with the drying chamber 3 and the baffle 10. The contour arrangement of the first spiral auger 13 and the baffle 10 allows the material at the bottom to move upward. A first motor 14 driving the first spiral auger 13 is fixedly arranged at the top of the equipment frame 1. The first motor 14 is a mature prior art, which will not be described in detail here. The first motor 14 is centrally controlled by a control module. The first motor 14 is controlled by the control module to work, and the first spiral auger 13 is driven to make the material circulate up and down in the drying chamber 2. A feed hopper 4 is fixedly arranged on the side of the equipment frame 1. The feed hopper 4 is a mature prior art, which will not be described in detail here. The feed hopper 4 is arranged on the side of the equipment frame 1, and its bottom opening is connected to the top of the feed port 7. The material is poured into the feed port 7 on the side of the equipment frame 1 through the feed hopper 4 .

[0027] In order to realize the material transportation. In this embodiment, see Figure 2 and Figure 3 , a transmission mechanism 5 for transporting materials to the drying chamber 2 is arranged inside the equipment frame 1. The transmission mechanism 5 includes a second spiral auger 51 which is arranged vertically and rotates inside the feeding chamber 8, and the top of the second spiral auger 51 passes through the top of the equipment frame 1. A second motor 52 for driving the second spiral auger 51 is fixedly arranged at the top of the equipment frame 1. The second motor 52 is a mature existing technology and will not be described in detail here. The second motor 52 is centrally controlled by the control module. The second motor 52 is controlled by the control module to work, and the second spiral auger 51 is driven to transport the material in the feed port 7 to the inside of the drying chamber 2, so as to realize the automatic supply of materials.

[0028] In order to achieve the sealing of the drying chamber and the discharge of materials. Figure 1-Figure 3, a discharge port 6 connected to the bottom end of the drying chamber 2 is provided on the equipment rack 1 at the bottom end of the drying chamber 2. The inner bottom surface of the discharge port 6 is an inclined surface that slopes downward from the inside to the outside. It is convenient for the discharge of the material after drying. A support plate 15 that can slide outward and cover the opening at the bottom end of the drying chamber 2 is provided between the discharge port 6 and the communication position of the drying chamber 2. Electric push rods 16 are fixedly provided on the equipment racks 1 on both sides of the bottom end of the drying chamber 2, and the electric push rods 16 are centrally controlled by the control module. The telescopic end of each electric push rod 16 is fixedly provided to the top end of the side of the support plate 15. By moving the support plate 15, the closure and communication between the bottom end of the drying chamber 2 and the discharge port 6 can be achieved, which is convenient for drying and discharging the material.

[0029] The method of using the material drying device for high-purity alumina ceramic production of the utility model is as follows: First, the control module controls the two electric push rods 16 to work synchronously, and drives the support plate 15 to move inward to block the bottom of the drying chamber 2. Then the material is poured into the feed hopper 4, and the material enters the bottom of the feeding chamber 8 through the feed port 7. The control module controls the second motor 52 to work, and the second motor 52 drives the second spiral auger 51 to rotate, and the alumina material entering the feeding chamber 8 is conveyed upward until it enters the interior of the drying chamber 2 through the feed port 9. In this process, the material is fully entered into the feeding chamber 8 through the inclined surfaces of the feed hopper 4 and the feed port 7. The control module controls the first motor 14 to work, and drives the first spiral auger 13 to rotate. At this time, the material moves upward from the inner ring of the drying chamber 3 in the drying chamber 2 until it moves downward from the top of the drying chamber 3 along the outer ring of the drying chamber 3, forming a cycle. In this process, the first spiral auger 13 and the baffle 10 are arranged in a contoured manner so that the material at the bottom can also move upward.

[0030] Then the heated hot air is discharged into the drying chamber 3 through the vent hole to heat the drying chamber 3. At this time, the hot air moves upward in the drying chamber 3 through the spiral partition 11, so that all parts of the drying chamber 3 can release heat to the outside. In this way, the material circulating up and down is heated, so that the material is fully in contact with the heat source and heated evenly, avoiding uneven drying. After drying for a period of time, the control module controls the two electric push rods 16 to work synchronously, so that the support plate 15 moves outward, and the dried material is discharged through the discharge port 6. In this process, the inclined surface of the inner bottom surface of the discharge port 6 makes the material discharge smoother to avoid blockage.
