Structural and working principle of electric blast drying oven

The outer casing of the digital electric heating constant temperature blast drying oven is stamped and welded by steel plate and welded. The surface of the outer casing is treated with high-strength electrostatic spray coating, and the paint film is smooth and firm. The studio is made of carbon steel or mirror stainless steel, and the insulation between the studio and the outer casing is filled with insulation cotton. A sample shelf is placed inside the studio for placing various test items. The back of the studio is equipped with electric heating elements and a centrifugal fan impeller. After the heated air passes through the fan, it circulates in the working chamber, so the temperature of the working chamber is relatively uniform. The door seal is made of silicone rubber strip sealing box with a sight glass for observation. The back of the outer casing is provided with inlet and exhaust holes, and the amount of exhaust can be adjusted by itself. In this article, I will introduce the structure and working principle of the electric blast drying oven.

The left side of the electric heating blast drying box is an electrical box, and the front panel of the electric box is equipped with a temperature control instrument and a power switch. Electrical components are housed in the electrical box. In order to meet the needs of different users, the series of drying ovens are available in three temperature control systems.

1. The economical series of drying ovens use an electronic temperature controller for temperature setting and control. A mercury thermometer is inserted from the top of the drying oven to display the temperature. The temperature control system has a reliable temperature control performance and is convenient to use.

2. Basic and stainless steel series drying ovens use intelligent digital temperature controller for temperature setting, display and control. The temperature regulator uses computer technology to collect and process the temperature signal in the working chamber, so that the temperature in the working chamber can be automatically kept at a constant temperature.

3.Stainless steel type drying ovens can also be equipped with intelligent program temperature regulator for temperature setting, display and control. The temperature control system can set and control the working temperature, the constant temperature, the heating time and the constant temperature time in a plurality of temperature sections. The temperature regulator uses computer technology to collect and process the temperature signal in the working chamber to automatically maintain the temperature in the working chamber at a constant temperature. The temperature control system belongs to the P.I.D intelligent temperature control performance and is convenient to use. It can be programmed according to the needs of the experiment. Intelligent temperature regulators have over temperature protection. During the operation of the equipment, if the temperature in the working chamber exceeds the set temperature value, the over-temperature protection circuit action will cut off the heating circuit.

Electric blast drying oven is widely used in the electromechanical, chemical, plastic, light industry and other scientific research units to bake, dry, cure, heat treat and other aspects of various products and samples. Next, let me introduce the characteristics of the electric blast drying oven.

1. Electric blast drying oven is suitable for measuring moisture in coal, drying articles, drying heat treatment and other heating.

2. This series of oven adopts digital display temperature controller for temperature control, temperature control sensitivity, easy operation and reliable performance. The digital display directly shows the working temperature and is easy to read.

3. The temperature of the studio can be any constant temperature between room temperature and 300 °C; it can automatically cut off the power supply and protect equipment and products.

4. The oven is an indispensable device for laboratory and scale production.

Below, I will give you a brief introduction to the working principle of the electric blast drying oven.

1. Electric blast drying box structure

(1) The design is perfect, and the box body is machined by CNC machine tool. The door is double-open and easy to operate.

(2) The door system is opened on the side of the circuit system for easy maintenance and overhaul.

(3) The door can be closed tightly and can be adjusted. The integrally formed silicone rubber door seal ring ensures the tightness of the oven.

(4) The inner liner is made of SUS304 stainless steel plate, and the outer casing is sprayed with A3 plate, which is more smooth and beautiful.

2. Electric blast drying oven control execution system

(1) The temperature controller adopts touch button, digital display LED display, PID intelligent control instrument;

(2) Pt100 platinum resistance temperature sensor;

3. Electric blast drying oven protection system

(1) The whole machine protection system consists of over-temperature protection and alarm devices.

(2) This guarantees the integrity of the components and test pieces.
