Description

Technical Field

[0001] This utility model belongs to the field of alumina powder processing technology, and more specifically, it relates to a drying device for alumina powder production. Background Technology

[0002] In the production process of alumina powder, the drying stage plays a crucial role, directly affecting product quality, production efficiency, and the feasibility of subsequent processing. With technological advancements, microwave technology has gradually emerged in the drying field and has been introduced into the alumina powder drying process, leading to the development of belt microwave dryers. The core principle of microwave drying is the interaction between microwaves and material molecules. As a high-frequency electromagnetic wave, microwaves can penetrate materials, causing water molecules within the material to vibrate and rub at high speed under the influence of the microwave electromagnetic field, thereby generating heat and achieving rapid heating from the inside out. Compared to traditional hot air drying, this process has significant advantages.

[0003] Based on the above, when existing alumina powder is dried in a microwave dryer, it is generally fed continuously by a conveyor belt. A large amount of alumina powder is poured into the drying equipment at one time, which can easily cause problems such as uneven drying, local overheating, or energy waste. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a drying device for alumina powder production. This device solves the problem that existing alumina powder drying methods typically involve continuous feeding of alumina powder via a conveyor belt, resulting in a large influx of powder into the drying equipment at once, which can easily lead to uneven drying, localized overheating, or energy waste.

[0005] The purpose and effectiveness of this utility model's drying device for alumina powder production are achieved through the following specific technical means:

[0006] A drying device for alumina powder production includes a drying support frame, a microwave dryer body, a drying conveyor belt, a conveyor drive motor, a feed hopper, a feed drive motor, a drying adjustment mechanism, and a feed distribution mechanism. The microwave dryer body is fixedly connected above the drying support frame. The drying conveyor belt is positioned above the drying support frame. The conveyor drive motor is fixedly connected to the upper right side of the drying support frame and is drively connected to the drying conveyor belt. The feed hopper is fixedly connected to the upper front end of the drying support frame. The feed drive motor is fixedly connected to the lower right side of the feed hopper. The drying adjustment mechanism is positioned below the rear end of the feed hopper. The feed distribution mechanism is positioned inside the lower end of the feed hopper.

[0007] Furthermore, the drying adjustment mechanism includes: an adjustment limit plate, an adjustment baffle, and an adjustment screw; the adjustment limit plate is fixedly connected to the lower rear end of the feed hopper, and a sliding groove structure is provided on the inner side of the adjustment limit plate; the adjustment baffle is slidably connected to the inner side of the sliding groove of the adjustment limit plate; the adjustment screw is rotatably connected to the upper part of the adjustment limit plate, and the adjustment screw is threadedly connected to the adjustment baffle.

[0008] Furthermore, the feeding distribution mechanism includes: a feeding distribution baffle and a feeding limiting slide groove; the feeding distribution baffle is fixedly connected to the lower end of the inside of the feeding hopper; the feeding limiting slide groove is opened on the inner side of the feeding distribution baffle.

[0009] Furthermore, the feeding distribution mechanism also includes: a distribution drive screw and a distribution agitator; the distribution drive screw is a reciprocating screw structure, and the distribution drive screw is coaxially fixedly connected to the left side of the rotating shaft of the feeding drive motor; the distribution agitator is slidably connected to the inner side of the feeding limit slide groove, and the distribution agitator is threadedly connected to the distribution drive screw.

[0010] Furthermore, the feeding distribution mechanism also includes a distribution control plate; the distribution control plate is hinged to the lower end of the inside of the feeding hopper.

[0011] Furthermore, the feeding distribution mechanism also includes: a first drive gear, a second drive gear, and a distribution reset spring; the first drive gear is an incomplete gear structure, and the first drive gear is coaxially fixedly connected to the left side of the rotating shaft of the feeding drive motor; the second drive gear is coaxially fixedly connected to the right end of the rotating shaft of the distribution control plate, and the second drive gear meshes with the first drive gear; the distribution reset spring is a right-angle spring structure, and the distribution reset spring is fixedly connected to the left end of the rotating shaft of the distribution control plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention, through the setting of a drying adjustment mechanism, allows alumina powder to be placed inside the feed hopper. By rotating the adjustment screw, the adjustment baffle moves up and down, thereby adjusting the thickness of the alumina powder layer and improving the applicability of the entire device.

[0014] This invention utilizes a feeding distribution mechanism. When the feeding drive motor is activated, its shaft rotates, causing the distribution drive screw to rotate. This rotation of the distribution drive screw then moves the distribution agitator left and right, agitating the alumina powder and preventing bridging, thus ensuring stable feeding. Simultaneously, a feeding distribution baffle shields the distribution drive screw, preventing alumina powder contamination and ensuring stable transmission. Furthermore, the rotation of the feeding drive motor shaft also drives the first drive gear. Once the first drive gear meshes with the second drive gear, the second drive gear is also driven to rotate, which in turn drives the distribution control plate to rotate. The system automatically seals the bottom of the feed hopper. After the first drive gear disengages from the second drive gear, the distribution control plate resets under the action of the distribution reset spring. The distribution control plate then reciprocates, enabling segmented feeding of alumina powder. This avoids continuous feeding of alumina powder, optimizes the feeding rhythm, and improves the drying efficiency of alumina powder. On the other hand, it provides the drying equipment with sufficient time for efficient and uniform heat exchange of each batch of alumina powder, ensuring that the moisture inside the powder can be fully evaporated, thus significantly improving drying efficiency. Precise segmented feeding also makes the entire production process more controllable. Operators can flexibly adjust the feeding rhythm according to the real-time operating conditions of the drying equipment, further optimizing the production process and improving production efficiency.

[0025] The drying adjustment mechanism includes: an adjustment limit plate 101, an adjustment baffle 102, and an adjustment screw 103; the adjustment limit plate 101 is fixedly connected to the lower rear end of the feed hopper 5, and a sliding groove structure is provided on the inner side of the adjustment limit plate 101; the adjustment baffle 102 is slidably connected to the inner side of the sliding groove of the adjustment limit plate 101; the adjustment screw 103 is rotatably connected to the upper part of the adjustment limit plate 101, and the adjustment screw 103 is threadedly connected to the adjustment baffle 102.

[0026] The specific usage and function of this embodiment are as follows: When it is necessary to dry alumina powder, the alumina powder is placed inside the feed hopper 5, and the adjusting screw 103 is rotated. The rotation of the adjusting screw 103 drives the adjusting baffle 102 to move up and down. The up and down movement of the adjusting baffle 102 realizes the adjustment of the thickness of the alumina powder, which improves the applicability of the entire device. Then, the conveying drive motor 4 is turned on, and the conveying drive motor 4 drives the drying conveyor belt 3 to convey the alumina powder. The alumina powder is conveyed into the microwave dryer body 2, and the microwave dryer body 2 realizes the drying of the alumina powder.

[0027] Example 2: This utility model provides a drying device for alumina powder production, based on Example 1, such as... Figures 1 to 5 As shown, it also includes a feeding distribution mechanism, which is located at the lower end of the inside of the feeding hopper 5.

[0028] The feeding distribution mechanism includes: a feeding distribution baffle 601, a feeding limiting slide 602, a distribution drive screw 603, a distribution agitator 604, a distribution control plate 605, a first drive gear 606, a second drive gear 607, and a distribution reset spring 608. The feeding distribution baffle 601 is fixedly connected to the lower end of the inside of the feeding hopper 5. The feeding limiting slide 602 is opened on the inner side of the feeding distribution baffle 601. The distribution drive screw 603 is a reciprocating screw structure and is coaxially fixedly connected to the left side of the rotating shaft of the feeding drive motor 6.

The distribution control plate 605 then performs a reciprocating oscillation, which enables segmented feeding of alumina powder, avoids continuous feeding of alumina powder, and improves the drying efficiency of alumina powder.
