Description

Technical Field

[0001] This utility model relates to the field of ceramic drying technology, and in particular to a drying device for the production of ceramic handicrafts. Background Technology

[0002] Currently, in the production of ceramic handicrafts, it is necessary to dry ceramic products. The current drying equipment is usually based on hot air circulation. Through a drying chamber with a single air duct, hot air is generated by electric heating tubes or other heat sources. The hot air is sent into the chamber from one side and discharged from the other side to dry the ceramic blank. However, this single air supply method is prone to "wall-adhering effect" after entering the chamber. Due to the combined effect of airflow inertia and friction of the inner wall of the chamber, some hot air flows quickly along the inner wall of the chamber, while the airflow around the ceramic blank in the middle of the chamber is slow. As a result, the edges of the blanks near the inner wall of the chamber are prone to over-drying due to continuous strong airflow. Meanwhile, the blanks in the middle and bottom of the chamber dry slowly due to insufficient airflow, which ultimately affects the quality of the finished ceramic handicrafts.

[0003] Therefore, we propose a drying device for ceramic craft production to solve the above problems. Utility Model Content

[0004] This invention provides a drying device for the production of ceramic handicrafts to solve the problem of uneven drying of ceramic blanks in the prior art.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] A drying device for ceramic craft production includes a drying chamber and a hot air supply assembly. The interior of the drying chamber is provided with a support plate for placing ceramic products and coinciding with its axis. The support plate can rotate around its own axis. The hot air supply assembly includes a main air duct, an upper branch air duct, and a lower branch air duct for conveying hot air. One end of each of the upper and lower branch air ducts is connected to the main air duct. The output end of the upper branch air duct is connected to the upper part of the drying chamber and is arranged along the tangential direction of the drying chamber. The output end of the lower branch air duct is connected to the lower part of the drying chamber and is arranged along the tangential direction of the drying chamber, for forming a spiral converging airflow in the middle of the drying chamber.

[0007] Preferably, the airflow input from the upper air duct along the tangent of the drying chamber body rotates in the opposite direction to the airflow input from the lower air duct along the tangent of the drying chamber body within the drying chamber body.

[0008] Preferably, the hot air supply assembly further includes a hot air blower, the output end of which is connected to the input end of the main air duct.

[0009] Preferably, it also includes a temperature sensor for detecting the temperature inside the drying chamber and a controller electrically connected to the temperature sensor, wherein the controller is used to control the power of the hot air blower according to the temperature signal from the temperature sensor to adjust the drying temperature.

[0010] Preferably, the bottom of the drying chamber is provided with a driving component, the output shaft of which is connected to the support plate and is used to drive the support plate to rotate.

[0011] Preferably, the drying chamber is detachably connected to a lid, and the lid is provided with an exhaust pipe.

[0012] The beneficial effects of this utility model are as follows: by setting the upper and lower air distribution pipes in opposite directions along the tangent of the drying chamber, hot air is swirled in clockwise and counterclockwise directions respectively, and converges in the middle of the drying chamber. When they converge, the two spiral airflows collide with each other, forming a complex and powerful composite airflow field, which makes the hot airflow distribution in the drying chamber more uniform, and can more comprehensively cover the ceramic products on the central support plate, reduce airflow dead zones, and make the ceramics heat evenly and improve drying uniformity.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] Reference Figures 1-4 As shown, a drying device for ceramic craft production includes a drying chamber 1 and a hot air supply assembly for inputting hot air into the drying chamber 1. Inside the drying chamber 1, a support plate 11 is provided for placing ceramic products and is aligned with its axis. The support plate 11 can rotate around its own axis. The hot air supply assembly includes a main air duct 2 for conveying hot air, an upper branch air duct 21, and a lower branch air duct 22. One end of both the upper and lower branch air ducts 21 and 22 are connected to the main air duct 2. The output end of the upper branch air duct 21 is connected to the upper part of the drying chamber 1 and is arranged along the tangential direction of the drying chamber 1. The output end of the lower branch air duct 22 is connected to the lower part of the drying chamber 1 and is arranged along the tangential direction of the drying chamber 1, forming a spiral converging airflow in the middle of the drying chamber 1. The support plate 11 is horizontally positioned at the central axis of the drying chamber 1, with its edge aligned with the drying chamber 1. A 5-10cm gap is left between the inner walls to avoid obstructing airflow circulation. The air outlets of the upper air duct 21 and the lower air duct 22 are inclined at 5-10° toward the inside of the drying chamber 1 to guide the hot air to converge toward the middle of the drying chamber 1. When the hot air supply component is working, the main air duct 2 delivers the heated air to the upper and lower air ducts 22 respectively. The hot air delivered by the upper air duct 21 forms a rotating airflow in the upper part of the chamber in a clockwise direction. The two rotating airflows gradually approach and converge toward the middle of the drying chamber 1 during the rising and falling process, forming a spiral composite airflow field. This ensures uniform contact with the ceramic products placed on the support plate 11 in the middle of the drying chamber 1. It can both wrap the ceramic products on the support plate 11 and form a continuous airflow environment around the ceramic products, avoiding uneven drying caused by airflow stagnation and achieving uniform drying of the ceramic products.

[0021] Reference Figures 1-4 As shown, the airflow input from the upper air duct 21 along the tangential direction of the drying chamber 1 and the airflow input from the lower air duct 22 along the tangential direction of the drying chamber 1 rotate in opposite directions within the drying chamber 1. That is, one stream of hot air enters the drying chamber 1 and rotates clockwise, while the other stream rotates counterclockwise. These two streams rotate in opposite directions, creating a mutually opposing and mutually pulling airflow motion inside the chamber. This reverse rotation design, on the one hand, breaks the airflow stratification phenomenon that is easily formed by airflow in a single direction, avoiding drying differences caused by independent airflow in the upper and lower areas of the drying chamber 1; on the other hand, the vortex generated by the reverse rotation creates a continuous airflow impact and envelopment on the central area of ​​the drying chamber 1, ensuring that the ceramic products on the support plate 11, whether in the upper, middle, or lower position, are uniformly covered by hot airflow, making the hot air distribution inside the entire drying chamber 1 more balanced.

[0022] The hot air supply component also includes a hot air blower 23. The output end of the hot air blower 23 is connected to the input end of the main air duct 2. The hot air blower 23 adopts an industrial-grade hot air generator, which integrates a heating module and a blower impeller. It can draw in outside air and heat it to form hot air with a controllable temperature (for example, the hot air temperature can be adjusted within the range of 40-80℃ by adjusting the power of the heating module). The output end of the hot air blower 23 can be sealed to the input end of the main air duct 2 through a flange structure to ensure that there is no leakage during the hot air delivery process and reduce heat loss to provide a continuous and stable hot air source for the upper air duct 21 and the lower air duct 22.

[0023] Reference Figure 1 as well as Figure 4 As shown, further, it includes a temperature sensor 3 for detecting the temperature inside the drying chamber 1 and a controller 4 electrically connected to the temperature sensor 3. The controller 4 is used to control the power of the hot air blower 23 to adjust the drying temperature according to the temperature signal from the temperature sensor 3. When the temperature sensor 3 detects that the temperature inside the drying chamber 1 is not within the set threshold, it will transmit the temperature signal to the controller 4. The controller 4 adjusts the power of the hot air blower 23, which can change the temperature and air volume of the output hot air. For example, when a higher temperature hot air is required, the power of the hot air blower 23 can be increased; if a lower temperature hot air is required, the power can be reduced.

[0024] Reference Figure 3 As shown, a driving component 5 is further provided at the bottom of the drying chamber 1. The output shaft of the driving component 5 is connected to the support plate 11 and is used to drive the support plate 11 to rotate. The driving component 5 can be a geared motor or other device to drive the support plate 11 and the ceramic products placed on it to rotate slowly. During this process, the various sides of the ceramic products will alternately face the intersection area of ​​the upper clockwise airflow and the lower counterclockwise airflow, ensuring that every part of the product surface can receive the heating effect of the airflow evenly, avoiding local drying delays caused by the shape of the product itself. At the same time, the slow rotation speed will not disrupt the stability of the spiral converging airflow inside the drying chamber 1, so that the airflow and the ceramic products always maintain a continuous and uniform heat exchange, further improving the drying uniformity.

[0025] Reference Figure 2 as well as Figure 3 As shown, the drying chamber 1 is further detachably connected to a cover 6. The detachable connection method can be threaded connection or snap-fit, etc. When the cover 6 is removed, it is convenient to take out or put the ceramic products from the support plate 11. During the drying operation, the cover 6 is placed on the drying chamber 1 to reduce heat loss. The cover 6 is equipped with an exhaust pipe 61 to allow some of the hot air in the drying chamber 1 to be discharged, so as to avoid excessive air pressure in the drying chamber 1.
