Description

Technical Field

[0001] This utility model relates to an electric heating constant temperature drying oven, belonging to the field of ceramic brick drying equipment. Background Technology

[0002] Ceramic tiles are a type of building decoration material made primarily from natural minerals such as clay and quartz sand, sintered at high temperatures. They possess advantages such as high hardness, strong wear resistance, and strong corrosion resistance, and are mainly used for the decoration and protection of building walls and floors. After production, ceramic tiles typically require testing for parameters such as hardness and wear resistance. To prevent the influence of the ceramic tile's moisture content on the test results, they must be dried to a constant weight in a drying oven before testing. However, existing ceramic tile drying ovens suffer from poor heat distribution within the drying chamber due to the placement of the ceramic tiles, resulting in ineffective drying. For example, the electric heating drying oven with cleaning function disclosed in patent announcement number CN215724638U dries ceramic tiles by delivering hot air from bottom to top in the drying chamber. After placing the ceramic tiles in upper and lower layers, the ceramic tiles on the bottom layer are closer to the heat source and receive more heat, while the ceramic tiles on the top layer are farther from the heat source and are affected by the obstruction of the hot air by the lower ceramic tiles, so they receive less heat. The difference in heat received by the upper and lower ceramic tiles in the drying chamber is large, resulting in poor drying uniformity and poor drying effect. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide an electric heating constant temperature drying oven with better drying effect on ceramic bricks.

[0004] The electric thermostatic drying oven of this utility model includes a box body with a set of main support legs installed at the bottom. The box body contains a drying chamber, a heating chamber, and two air distribution chambers. The drying chamber is located in the upper middle part of the box body. The front wall of the box body has an opening corresponding to the drying chamber. A ceramic brick support is connected to the bottom wall of the drying chamber through a linear guide assembly. The ceramic brick support has multiple sets of left and right corresponding slots. The front end of the ceramic brick support is fixedly connected to a door panel that matches the opening. The heating chamber is located on the lower side of the box body. An electric heater is installed in the heating chamber. An air inlet is penetrating through the bottom wall of the heating chamber. An axial flow fan is installed corresponding to the air inlet. The two air distribution chambers are located on the left and right sides of the box body, respectively. Both air distribution chambers are connected to the heating chamber. Both air distribution chambers are connected to the drying chamber through several air outlets. The top wall of the box body has an exhaust port connected to the drying chamber.

[0005] Furthermore, the linear guide assembly includes two drawer rails, with the fixed rails of the two drawer rails respectively installed on the left and right sides of the bottom wall of the drying chamber, and the movable rails of the two drawer rails being fixedly connected to the ceramic tile bracket.

[0006] Furthermore, a sealing strip is installed on the front side wall of the housing corresponding to the opening.

[0007] Furthermore, multiple connecting columns are fixed on the top wall of the drying chamber, and baffles are fixedly connected between the lower ends of each connecting column, with the baffles correspondingly positioned below the exhaust port.

[0008] Furthermore, a handle is fixedly connected to the front side of the door panel.

[0009] Furthermore, two auxiliary support legs are fixedly connected to the door panel.

[0010] Furthermore, rollers are rotatably connected to the lower ends of both auxiliary legs.

[0011] The advantages of this utility model compared with the prior art are: The electric heating constant temperature drying oven of this utility model has air outlet and exhaust port set in the parallel direction of the ceramic tile installation surface. Therefore, the installation of ceramic tiles has little impact on the flow of hot air, so the temperature in the drying chamber tends to be constant and uniform, which allows the ceramic tiles to be heated evenly and the drying effect of ceramic tiles is better. The electric thermostatic drying oven of this utility model allows the ceramic tile support and slot to be pulled out of the oven body by pulling the door panel, which is facilitated by the drawer guide rails, thus making it easy to place and take out ceramic tiles.

[0014] The embodiments of this utility model will be further described below with reference to the accompanying drawings: Example 1: like Figures 1 to 4As shown, the electric thermostatic drying oven of this utility model includes a box body 3. A set of main support legs 1 are installed at the bottom of the box body 3, which serve as the support components for the entire drying oven. The box body 3 is provided with a drying chamber 4, a heating chamber 17, and two air distribution chambers 19. The drying chamber 4 is located in the upper middle part of the box body 3. An opening 9 is provided on the front wall of the box body 3 corresponding to the drying chamber 4. A ceramic tile support 12 is connected to the bottom wall of the drying chamber 4 through a linear guide assembly. The ceramic tile support 12 is provided with multiple sets of left and right corresponding slots 5, which are used for mounting ceramic tiles. The ceramic tile support 12 is fixedly connected to a door panel 10 that matches the opening 9. The heating chamber 17 is located on the lower side of the box body 3. An electric heater 18 is installed in the heating chamber 17. An air inlet 16 is penetrating through the bottom wall of the heating chamber 17. An axial flow fan 2 is installed corresponding to the air inlet 16. Two air distribution chambers 19 are located on the left and right sides of the box body 3, respectively. Both air distribution chambers 19 are connected to the heating chamber 17. Several air outlets 6 are connected between the two air distribution chambers 19 and the drying chamber 4. An exhaust port 7 connected to the drying chamber 4 is provided on the top wall of the box body 3.

[0015] In use, by pulling the door panel 10 forward, the ceramic tile support 12 and the slot 5 can be pulled out of the box 3 under the action of the linear guide component. The ceramic tile to be dried can then be placed in the corresponding slots 5 on the left and right. Then, closing the door panel 10 will retract the ceramic tile support 12 into the box 3, thus moving the ceramic tile into the drying chamber 4. The electric heater 18 will heat the gas in the heating chamber 17. The axial flow fan 2 will transport the hot air in the heating chamber 17 to the two air distribution chambers 19 and spray it into the drying chamber 4 through several air outlets 6, thereby drying the ceramic tile. The moisture generated during the drying process will be discharged through the exhaust port 7. Since the air outlets 6 and the exhaust port 7 are all located in the parallel direction of the ceramic tile mounting surface, the installation of the ceramic tile has little impact on the flow of hot air, thus making the temperature in the drying chamber 4 more constant and uniform. This allows the ceramic tile to be heated evenly, resulting in a better drying effect.

[0016] Example 2: like Figures 1 to 4 As shown, based on Example 1, Furthermore, the linear guide assembly includes two drawer rails 11. The fixed rails of the two drawer rails 11 are respectively installed on the left and right sides of the bottom wall of the drying chamber 4, and the movable rails of the two drawer rails 11 are fixedly connected to the ceramic tile support 12. The drawer rails 11 are compact in structure, stable in operation, safe and reliable, and can be purchased and used directly.

[0017] Furthermore, a sealing strip 8 is installed on the front side wall of the box 3 corresponding to the opening 9. The sealing strip 8 can improve the sealing between the opening 9 and the door panel 10, effectively prevent heat leakage, and thus improve the drying efficiency.

[0018] Furthermore, multiple connecting columns 20 are fixed on the top wall of the drying chamber 4, and a baffle 21 is fixedly connected between the lower ends of each connecting column 20. The baffle 21 is correspondingly arranged below the exhaust port 7. The baffle 21 can block the exhaust port 7, effectively preventing hot air from flowing out directly through the exhaust port 7, which can effectively increase the residence time of hot air in the drying chamber and improve the drying effect.

[0019] Furthermore, a handle 13 is fixedly connected to the front side of the door panel 10, making the opening and closing operation of the door panel 10 more convenient.

[0020] Furthermore, two auxiliary legs 14 are fixedly connected to the door panel 10. The auxiliary legs 14 can provide auxiliary support for the ceramic tile bracket 12 when ceramic tiles are placed, thereby improving structural stability.

[0021] Furthermore, rollers 15 are rotatably connected to the lower ends of both auxiliary legs 14. The rollers 15 can reduce the friction between the auxiliary legs 14 and the ground, making the door panel 10 move more smoothly.
