Sell vacuum oven, industrial oven and second-hand equipment at a low price
- Product description: The industrial oven is composed of angle steel and thin steel plate. In addition, the box is strengthened, the outer surface is repainted, and the shell and inner tank are filled with aluminum silicat
Product introduction
Working principle of industrial ovenThe temperature is controlled by the connection between the digital display instrument and the temperature sensor. The hot air circulation air supply mode is adopted. The hot air circulation system is divided into horizontal type and vertical type. After accurate calculation, the air source is driven by the air supply motor to drive the wind wheel through the electric heater to send the hot air to the air duct and then enter the oven working room, and the used air is sucked into the air duct to become the air source for circulating heating again, which can effectively improve the temperature uniformity. If the box door is opened and closed in use, the air supply and circulation system can quickly restore the operating state temperature value.
1. Structure of industrial oven
The industrial oven is an internal and external double-layer structure, the shell is an angle steel sheet, and the fiber material is filled between the internal and external double-layer shells. The fiber material used in industrial oven is mostly aluminum silicate, which can play the role of thermal insulation and form a reliable thermal insulation layer. The industrial oven is equipped with hot air circulation system and temperature measurement and control system.
2. Principle of industrial oven
When the industrial oven is working, the operator obtains the temperature value inside the industrial oven through the instrument and temperature sensor, and operates it through the control system. The hot air circulation heating mode of industrial oven has better gas fluidity than the ordinary heat dissipation heating mode, and can accelerate the drying speed of materials in industrial oven.
The hot air circulation system of industrial oven is composed of air supply motor, wind wheel and electric heater. The air supply motor drives the wind wheel to send out cold air. The cold air is heated by the electric heating equipment and carries heat energy into the oven working room of the industrial oven through the air duct. The hot air circulation system of the industrial oven is conducive to improving the uniformity of air temperature. The temperature value will be affected and change, and the uniformity of the hot air circulation system is conducive to restoring the temperature value of the working state at the maximum speed.
Precautions for industrial oven
1. Temperature: select 10 degrees higher than the actual use temperature. Calculate the actual temperature difference according to the process requirements to ensure the baking effect. For example: if the service temperature is 150 degrees, 220 degrees, 360 degrees and 440 degrees, the maximum design temperature shall be 500 degrees. 4 temperatures, if it is the same product. Thyristor is the best choice for control. Different products are used at low temperature. The temperature difference should be slightly larger. The actual use effect of 150 degrees and 220 degrees is not as good as that of low-temperature oven. Use a medium temperature oven of 500 degrees. The baking temperature difference of 150 degrees is 2 ~ 5 degrees higher than that of a low temperature oven of 250 degrees. It also depends on the quality of the manufacturer's equipment. The oven is divided into low temperature (0-250 ℃), medium temperature (250-600 ℃) and high temperature (600-1500 ℃) exceeding 1200 ℃. The company recommends heating with carbon silicon rod, which can be selected according to the process requirements of the product.
2. Feeding: how to put the product in, you can layer the oven, configure the tray and have the net disk. Solid disc, punching disc. If there are many, you can use material rack and frame. But note - a problem. Whether the operator is convenient to operate. For example: an oven with a height of 1500, a width of 1500 and a depth of 850mm. If you make a baking tray to put items, you should consider whether the operator can take it or not.
3. Place: if the oven is placed on the floor. Consider whether you can enter the door and the elevator.
The use environment of industrial oven is strictly prohibited to be close to flammable and explosive materials, such as Tianna water and paint. Otherwise, there is a risk of explosion. At the same time, the exhaust outlet of the industrial oven must be externally connected with the exhaust pipe. Most of the baked goods in rubber and oil paint will produce harmful gases to human body in high temperature environment F. if they are discharged in time, they will endanger personnel's health.
Classification of industrial ovens: precision oven, high temperature oven, constant temperature oven, vacuum oven, explosion-proof oven, dust-free oven, electroplating oven, nitrogen charging oven, infrared oven, trolley oven, trolley oven and constant temperature test oven
