Description

Technical Field

[0001] This utility model relates to the field of solid dehumidification equipment technology, specifically to a ceramic drying oven structure. Background Technology

[0002] In the ceramic production process, the drying stage affects the quality and yield of ceramic products. Ceramic drying ovens remove moisture from ceramic blanks, ensuring their stability in subsequent firing and other processes. Traditional ceramic drying methods, such as natural drying, are greatly affected by environmental factors and have long drying cycles, making them unsuitable for large-scale industrial production. Early simple hot air circulation drying ovens improved drying efficiency to some extent, but still have many shortcomings.

[0003] Firstly, existing equipment generally suffers from uneven heating and unreasonable airflow distribution in terms of heating and airflow circulation. This results in uneven heating of the ceramic blanks during the drying process, easily leading to defects such as cracking and deformation, thus affecting product quality. For example, in some traditional drying ovens, ceramic blanks closer to the heat source dry too quickly, while those farther away dry too slowly, causing inconsistent quality within the same batch of products, resulting in a high scrap rate, increased production costs, and resource waste.

[0004] Secondly, there is a lack of effective means to control humidity during the drying process. Ceramic blanks release a large amount of moisture during drying; if this moisture is not drained in time, the humidity inside the drying chamber will rise sharply, negatively impacting the drying effect and efficiency. Most traditional equipment lacks humidity monitoring and regulation mechanisms, relying solely on manual experience to determine whether ventilation is needed, making it difficult to control the humidity of the drying environment. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a ceramic drying oven structure, comprising an oven body with a door hinged to the front wall. The key features are: a perforated partition plate at the lower end of the oven body, dividing the oven body into a drying chamber and a heating chamber, with multiple electric heating rods installed within the heating chamber; multiple perforated storage plates for placing ceramics within the drying chamber, dividing the drying chamber into multiple storage compartments, which are slidably connected to the oven body; a fan installed at the top of the oven body, with its inlet connected to an air supply duct, the other end of which communicates with the heating chamber of the oven body; and branch pipes connected to the outlet of the fan, each branch pipe communicating with a specific storage compartment within the oven body; and a support plate fixed at the upper end of the oven body, with a modified cellulose moisture-absorbing plate slidably connected to the support plate.

[0006] Furthermore, an air passage is installed on the outer wall of the enclosure, which is connected to the inside of the enclosure, and a valve for opening and closing the air passage is installed on the outside of the air passage.

[0007] Furthermore, the box is a double-layer box, with the outer layer being galvanized steel plate and the inner layer being stainless steel plate, and ceramic fiber cotton filling the space between the outer and inner layers.

[0008] Furthermore, a temperature sensor is installed inside the drying chamber of the chamber, and a temperature warning light electrically connected to the temperature sensor is installed on the outer wall of the chamber door.

[0009] Furthermore, a humidity sensor is installed inside the drying chamber of the cabinet, and a humidity warning light electrically connected to the humidity sensor is installed on the outer wall of the cabinet door.

[0010] Furthermore, tracks are fixed to the inner wall of the box below both ends of the storage perforated plate, and rollers are installed at both ends of the bottom of the storage perforated plate.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This ceramic drying oven, through its rationally designed heating chamber, fan, and branch piping system, achieves uniform distribution and stable circulation of hot air within the drying chamber. Compared to traditional drying ovens, it ensures that each ceramic blank receives a uniform heat supply, effectively avoiding problems such as cracking and deformation caused by uneven heating.

[0013] 2. The combined use of temperature and humidity sensors with warning lights, along with the modified cellulose absorbent plate and air duct, enables the drying oven to accurately monitor and effectively regulate temperature and humidity during the drying process. This not only ensures drying efficiency but also guarantees that the ceramic blanks are dried in an optimal temperature and humidity environment, further improving product quality.

[0014] 3. The double-layer structure of the box and the filling of ceramic fiber cotton effectively improve the heat preservation performance, reduce heat loss, and reduce energy consumption; the sliding connection design of the storage plate and the reasonable structure of the box door facilitate the placement and removal of ceramic blanks, reducing the risk of damage to the blanks during operation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] A ceramic drying oven structure, such as Figure 1 and Figure 2 As shown, the equipment includes a housing 1, which serves as the outer shell of the entire device. It employs a double-layer structure design: the outer layer is made of galvanized steel sheet 102, possessing excellent corrosion resistance and mechanical strength to protect the internal structure from external environmental erosion; the inner layer is made of stainless steel sheet 101, capable of withstanding high temperatures and unlikely to chemically react with the ceramic blank, ensuring the purity of the drying process. Ceramic fiber cotton 103 is filled between the two layers, effectively improving the insulation performance of the housing 1 and reducing heat loss. The door is connected to the front wall of the housing 1 via hinges.

[0022] like Figure 1As shown, a partition plate 2 is installed at the lower end of the chamber 1, dividing the chamber 1 into a drying chamber and a heating chamber. Multiple electric heating rods 3 are evenly arranged in the heating chamber. The electric heating rods 3 are connected to an external power source through wires. The power can be adjusted according to the preset heating program or manually by the operator to realize the heating operation of the heating chamber and provide a stable heat source for the drying process.

[0023] Multiple perforated plates 4 are installed inside the drying chamber. The perforated plates 4 are slidably connected to the rails 16 on the inner wall of the chamber 1 via rollers 17 at both ends of the bottom, making it convenient for operators to place or remove ceramic blanks on the perforated plates 4. The perforated plates 4 divide the drying chamber into multiple storage compartments, each of which can independently hold ceramic blanks of different specifications or batches, improving space utilization and drying flexibility.

[0024] like Figure 1 and Figure 2 As shown, a fan 5 is installed on the top of the housing 1. The air inlet of the fan 5 is connected to the heating chamber through an air supply pipe 6, and the air outlet is connected to each of the storage chambers through branch pipes 7. After the fan 5 is started, it draws in the hot air from the heating chamber and then evenly delivers it to each storage chamber, so that the hot air forms a stable circulating airflow in the drying chamber, ensuring that each ceramic blank can fully contact the hot air and achieve uniform drying.

[0025] A modified cellulose moisture-absorbing plate 9 is slidably connected to a support plate 8 at the upper end inside the chamber 1. The modified cellulose moisture-absorbing plate 9 can absorb excess moisture in the drying chamber and maintain a stable relative humidity in the drying environment. When the moisture-absorbing plate has absorbed a certain amount of moisture, it can be removed through the chamber door for replacement or drying treatment for reuse.

[0026] like Figure 1 As shown, an air duct 10 is installed on the outer wall of the enclosure 1, and the air duct 10 is connected to the inside of the enclosure 1. The valve 11 can control the opening and closing of the duct. When the temperature or odor gas concentration inside the enclosure 1 is too high, the valve 11 can be opened to allow the gas inside the enclosure to be discharged and refresh the air environment inside the enclosure.

[0027] Temperature sensor 12 and humidity sensor 14 are installed inside the drying chamber to monitor the temperature and humidity inside the chamber, respectively. The sensors are electrically connected to temperature warning light 13 and humidity warning light 15 on the outer wall of the chamber door. When the temperature or humidity exceeds the preset range, the corresponding warning light will illuminate to remind the staff to take measures, such as opening valve 11 to cool down or replacing the moisture-absorbing plate, to ensure the normal operation of the drying process.

[0028] The working principle of this utility model is as follows:

[0029] Before using this ceramic drying oven, the operator should first place the ceramic blanks to be dried on the perforated plate 4 of the drying chamber, close the oven door, and ensure that the oven body 1 is well sealed. Then, based on factors such as the type, quantity, and initial moisture content of the ceramic blanks, the operator should set parameters such as the heating power of the electric heating rod 3, the speed of the fan 5, and the warning values ​​for temperature and humidity in the control system.

[0030] After the equipment is started, the electric heating rod 3 begins to work, rapidly heating the air in the heating chamber. The heated air is drawn into the fan 5 through the air supply duct 6 by the fan 5, and then the fan 5 delivers the hot air evenly to each storage chamber through the branch duct 7. The hot air comes into full contact with the ceramic blank in the storage chamber, causing the moisture on the surface of the blank to evaporate quickly.

[0031] As the drying process proceeds, the ceramic blank releases a large amount of moisture, and the humidity inside the drying chamber gradually increases. At this time, the modified cellulose moisture-absorbing plate 9 begins to absorb excess moisture from the air, maintaining the relative humidity inside the drying chamber within a certain range. Simultaneously, the humidity sensor 14 monitors humidity changes in real time. When the humidity reaches the preset upper limit, the humidity warning light 15 illuminates, prompting staff to check the moisture absorption status of the moisture-absorbing plate. If the moisture-absorbing plate is close to saturation, it needs to be replaced promptly.

[0032] During the heating and drying process, the temperature sensor 12 continuously monitors the temperature inside the drying chamber. If the temperature exceeds the preset safe range due to excessive heating time or other reasons, the temperature warning light 13 will illuminate. The operator can open the valve 11 of the air passage 10 as needed to allow some hot air to escape from the chamber 1 and introduce outside cold air for cooling, ensuring that the ceramic blank is dried in a suitable temperature environment and avoiding damage to the blank due to excessive temperature.

[0033] Once the moisture content of the ceramic blanks reaches the expected drying standard, turn off the equipment, open the chamber door, and easily remove the dried ceramic blanks using the sliding structure of the perforated plate 4, completing one drying operation. The above steps can then be repeated for the drying of the next batch of ceramic blanks.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
