Abstract
Description
Technical Field
[0001] This utility model relates to the field of material drying, and specifically to an electric heating drying oven. Background Art
[0002] With the continuous development of industries, scientific research, laboratories and other fields, the demand for material drying is becoming increasingly diversified. Different materials and different processes have different requirements for conditions such as drying temperature, humidity and time.
[0003] Electric heating drying ovens often have only one temperature zone and cannot meet the needs of different drying temperatures for various materials or different stages of the same material. This results in the need for multiple devices or frequent adjustment of temperature settings in practical applications, increasing the operational complexity and cost. Content of the Utility Model
[0004] In order to overcome the above deficiencies, this utility model provides an electric heating drying oven.
[0005] The technical solution adopted by this utility model:
[0006] An electric heating drying oven, including a frame. Inside the frame, three drying ovens arranged side by side from left to right are fixedly connected. The three drying ovens have the same structure. A pressure relief valve is fixedly connected to the top of the drying oven. The front side of the drying oven is open and rotatably connected with a door. A heat source device is fixedly installed on the rear side wall of the drying oven. Heating pipes are fixedly installed on both the left and right inner side walls of the drying oven. The rear ends of the two heating pipes are fixedly connected to the output end of the heat source device. There are two partitions between the two heating pipes. The two partitions are distributed left and right. The partitions are in a hollowed-out shape and are fixedly connected to the inner wall of the drying oven. A number of bottom grooves are opened on the inner bottom wall of the drying oven. The bottom grooves are evenly and parallelly distributed.
[0007] Advantages of this Utility Model
[0008] This utility model is integrally divided into three drying ovens with different temperatures. Each drying oven is independent and can independently control the temperature, capable of simultaneously meeting the drying needs of different materials, improving the flexibility and usage efficiency of the device. By independently controlling the temperature of each drying oven, precise temperature control of different materials or different stages of the same material can be achieved, ensuring the drying effect and quality.

[0017] As Figures 1-7 shown: An electrothermal drying oven, comprising a frame 1, inside which there are fixedly connected three drying ovens 2 arranged side by side from left to right. The three drying ovens 2 have the same structure. The top of the drying oven 2 is fixedly communicated with a pressure relief valve 3. The front side of the drying oven 2 is open and rotatably connected with a box door 4. The rear side wall of the drying oven 2 is fixedly installed with a heat source device 5. The left and right inner side walls of the drying oven 2 are both fixedly installed with heating pipes 6. The rear ends of the two heating pipes 6 are fixedly connected with the output end of the heat source device 5. There are two partition boards 7 between the two heating pipes 6. The two partition boards 7 are distributed left and right. The partition board 7 is in a hollow shape and is fixedly connected with the inner wall of the drying oven 2. The inner bottom wall of the drying oven 2 is provided with a plurality of bottom grooves 8. The bottom grooves 8 are evenly and parallelly distributed.
[0018] When the electrothermal drying oven starts to work, first start the heat source device 5 (such as an electric heating element, a heater, etc.) behind each drying oven 2. After the heat source device 5 is started, it will generate heat and transfer the heat to the two connected heating pipes 6 through its output end.
[0019] After receiving the heat, the heating pipes 6 will quickly heat up and evenly dissipate the heat into the internal space of the drying oven 2. Since the heating pipes 6 are distributed on the left and right sides of the drying oven 2, the uniformity of the temperature distribution inside the box can be ensured.
[0020] Each drying oven 2 is an independent unit and can separately control the temperature inside it, which is usually achieved by adjusting the power or working time of the heat source device 5.
[0021] Since the three drying ovens 2 are arranged side by side and have the same structure but are independent of each other, different temperature conditions can be set according to needs to meet the drying requirements of different materials or products.
[0022] During the heating process, the air inside the drying oven 2 expands due to the temperature rise, increasing the pressure. To maintain the pressure stability inside the oven and prevent overheating, a pressure relief valve 3 is fixedly connected to the top of the drying oven 2. When the pressure inside the oven exceeds the set value, the pressure relief valve 3 will automatically open to release the excess steam or gas, ensuring the safe operation of the equipment.
[0023] Meanwhile, the front side of the drying oven 2 is open and equipped with a door 4, facilitating the opening for putting in or taking out materials when needed, as well as operations such as ventilation.
[0024] The material to be dried is placed on the bottom trough 8 inside the drying oven 2, and heat can heat the bottom of the material along the bottom trough 8. The design of the bottom trough 8 enables the material to be evenly distributed and receive heat from the heating tubes 6. Since the bottom troughs 8 are evenly and parallelly distributed, it can ensure that the material is evenly heated during the drying process, improving the drying efficiency.
[0025] The hollow design of the partition 7 not only helps with the transfer and distribution of heat but also can prevent the material from directly contacting the heating tubes 6 to a certain extent, avoiding local overheating or charring.
[0026] The present utility model only protects the mechanical part, and the functions realized through the software control part related thereto are not within the protection scope of the present utility model.
