Description

Technical Field

[0001] This utility model relates to the field of ceramic production technology, specifically to a device for uniformly drying ceramic products. Background Technology

[0002] After ceramic products are formed, they need to undergo an air-drying process to remove internal moisture and prevent cracking or deformation during subsequent firing. The quality and efficiency of the air-drying process directly affect the yield and physical properties of ceramic products, making it an indispensable and crucial step in ceramic production.

[0003] Existing ceramic product air drying equipment mainly comes in the following forms:

[0004] Natural air drying relies on ambient temperature and air flow to achieve drying. This method is inefficient, has a long cycle, and is greatly affected by ambient humidity and temperature, often resulting in uneven drying or local cracking of products.

[0005] Hot air drying chambers use hot air to force-dry products. The wind speed and temperature are adjustable, which improves the drying efficiency. However, most of these devices have simple structures and fixed airflow paths. Ceramic products are usually stationary or rotate on a single axis, which can easily lead to the windward side being over-dried and the leeward side being under-dried, resulting in uneven stress or even cracking.

[0006] The hot air circulation system combined with the rotating tray structure improves the drying uniformity to some extent, but there are still problems such as a single rotation mode and insufficient airflow disturbance. For ceramic parts with complex structures or irregular surfaces, the phenomenon of uneven drying is still quite prominent.

[0007] In addition, some high-end ceramic products have high requirements for the uniformity of the drying process and the control of temperature and humidity. However, existing technologies often lack the ability to dynamically adjust the position of ceramic products during the drying process, and also lack a precise calibration structure for the center of gravity of ceramic products. This can easily cause rotational imbalance or drying dead zones, which seriously affect the consistency and quality stability of the products.

[0008] Therefore, there is an urgent need for a new type of ceramic product drying device that can achieve multi-directional disturbance, uniform airflow circulation, controllable temperature and humidity, and center of gravity adjustment during the drying process, thereby solving existing problems such as uneven drying, high cracking rate, and low efficiency. Utility Model Content

[0009] This invention aims to solve the technical problems existing in the air-drying process of ceramic products, such as uneven drying, easy local cracking, high energy consumption and low degree of automation, and to provide a ceramic product uniform air-drying device with novel structure, stable operation, high drying efficiency and good uniformity.

[0010] To achieve the above objectives, this utility model provides a device for uniformly drying ceramic products, comprising:

[0011] The circulating air duct assembly includes a return pipe, a duct fan, a connecting pipe, and a gas heating box, forming a closed hot air circulation path;

[0012] The drying chamber is a hollow, sealed structure used to contain the drying process of ceramic products and is connected to both ends of the circulating air duct assembly.

[0013] An omnidirectional air drying rack is installed inside the air drying chamber and includes a first ring seat, a second ring seat, and a third ring seat that are nested in sequence. Each ring seat forms a mutually perpendicular rotational structure through a shaft seat.

[0014] A drive motor, mounted on the top of the drying chamber, is used to drive the first ring seat to rotate;

[0015] The tooling assembly, installed on the surface of the third ring seat, is used to support the ceramic products to be air-dried. The bottom is equipped with a lifting and adjusting assembly to align the center of the ceramic product with the center of rotation.

[0016] During operation, hot air circulates and heats in the circulating air duct assembly before entering the drying chamber. The ring seat structure rotates with multiple degrees of freedom under the action of the drive motor, causing the surface of the ceramic product to continuously and irregularly change orientation, thereby achieving full-coverage and uniform drying of the product surface by hot air.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] 1. Omnidirectional Disturbance Drying Structure: The multi-axis rotating ring seat structure drives the ceramic products to deflect in multiple directions, effectively overcoming the problem of uneven drying in traditional fixed or single-axis rotating structures;

[0019] 2. Hot air closed-loop circulation system: Improves thermal energy utilization efficiency, saves energy consumption, and enhances the stability of the drying environment through temperature control and dehumidification components;

[0020] 3. High drying efficiency and low risk of cracking: It achieves a fast and uniform drying process, significantly reducing the rate of ceramic cracking and improving the yield. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0031] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0032] The following is in conjunction with the appendix Figures 1-5 This invention describes a ceramic product uniform air-drying device provided by some embodiments of the present invention.

[0033] like Figures 1 to 5 As shown in the figure, this utility model embodiment provides a uniform air drying device for ceramic products, which mainly includes: a circulating air duct assembly 100, an air drying chamber 200, an omnidirectional air drying rack 300, and a tooling assembly 400.

[0034] The air-drying chamber 200 is a hollow, sealed structure used to contain the air-drying space. Its outer surface is provided with a gate 210 and a support frame 220. A drive motor 230 is installed on the top of the support frame. The drive motor is fixedly connected to the top of the air-drying chamber 200 and extends into the interior of the chamber through its output shaft.

[0035] The drying chamber 200 is connected to the circulating air duct assembly 100 at both ends. The circulating air duct assembly 100 includes a return pipe 110, a duct fan 120, a connecting pipe 130, and a gas heating box 140. The return pipe 110 is connected to one end of the drying chamber 200, and the connecting pipe 130 is connected to the other end.

[0036] The ducted fan 120 is located between the return pipe 110 and the connecting pipe 130 to drive the hot air circulation; the air heating box 140 is located at the interface between the return pipe 110 and the air drying chamber 200 to heat the airflow entering the air drying chamber.

[0037] Optionally, the gas heating chamber 140 is also equipped with a temperature control unit and a dehumidifier to achieve precise control of airflow temperature and humidity, providing a constant temperature and dry environment.

[0038] Omnidirectional air drying rack structure: The air drying chamber 200 is equipped with an omnidirectional air drying rack 300. This air drying rack structure can realize multi-axis rotation and disordered deflection of ceramic products, improving the comprehensiveness and uniformity of air drying.

[0039] Specifically:

[0040] The omnidirectional air drying rack 300 includes, in sequence, a first ring seat 310, a second ring seat 320, and a third ring seat 330;

[0041] The first ring seat 310 is axially connected to the inner wall of the drying chamber 200 and is fixedly connected to the output end of the drive motor 230 to achieve active rotation.

[0042] The second ring seat 320 is rotatably mounted inside the first ring seat 310 via the bearing seat 340, and the third ring seat 330 is also rotatably mounted inside the second ring seat 320 via the bearing seat 340.

[0043] The rotation axes of the three ring seats are perpendicular to each other. When the drive motor 230 drives the first ring seat 310 to rotate, the second ring seat 320 and the third ring seat 330 form a multi-axis nonlinear deflection motion inside due to rotational inertia and structural coupling, thereby realizing all-round disturbance and flipping of ceramic products and significantly improving the uniformity of hot air contact.

[0044] Tooling and self-aligning structure: The tooling assembly 400 is mounted on the surface of the third ring seat 330 to support the ceramic products to be air-dried. To ensure smooth rotation and keep the center of the ceramic product at the center of rotation, a lifting adjustment component is provided at the bottom of the tooling assembly. This component can be a manual screw drive mechanism or an adjustable telescopic rod structure, to align the center of the ceramic product with the center of the third ring seat 330, thereby enhancing the stability and symmetry of the rotation and avoiding wobbling or offset problems caused by eccentricity.

[0045] Additional explanation of the circulating air system: The ducted fan 120 is connected between the return pipe 110 and the connecting pipe 130, driving the heated airflow from the return pipe 110 into the drying chamber 200, passing over the surface of the ceramic product and then flowing into the connecting pipe 130, and finally returning to the air heating box 140, forming a closed hot air circulation system.

[0046] The gas heating box 140 is equipped with a heater, a thermostat and a dehumidification unit to maintain a constant temperature and suitable humidity of the internal airflow and avoid local overheating or uneven drying.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
