A belt dryer is a common and effective drying equipment, which is widely used in chemical, food, pharmaceutical, and other fields. In the working process of the belt dryer, the discharge box plays a key role, responsible for collecting the dried materials.
In order to ensure the accuracy and reliability of the discharge process, it is a common choice to use a radar level meter to measure the level of the discharge box of the belt dryer.
The discharge box of a belt dryer usually consists of an inclined container and a discharge opening. During the drying process, the material is conveyed from the dryer to the discharge box and then discharged through the outlet.
The discharge box has the following characteristics: Inclined design: The inclined design of the discharge box can promote the natural flow of materials and avoid material accumulation and blockage, thus ensuring the smoothness and stability of the discharge. Wear-resistant material:
Since the material will be constantly sliding and rubbing inside the discharge box, the discharge box needs to be made of wear-resistant material to improve its durability and service life. Connection of conveying equipment:
The discharge box is usually connected with the conveying equipment of the belt dryer (e.g. screw conveyor) to ensure that the dried material can be smoothly transported to the discharge box.
Let’s take the pickling production process in the chemical industry using belt dryers as an example to introduce the practical measurement application of radar level meters in the discharge box of belt dryers.
In the pickling production process, the belt dryer is widely used in the drying process of zinc-plated steel sheets.
During the drying process, the zinc-plated steel sheet needs to pass through the dryer of the belt dryer, and the material is collected and discharged through the discharge box. In order to ensure a smooth discharge process, the level of the material in the discharge box must be measured accurately.
As a non-contact level measurement device, a radar level meter is widely used in the discharge box of belt dryers. It uses microwave signals to measure the distance between the material and the sensor, so as to derive the accurate value of the level.
Compared with other traditional level measurement technology, radar level meter has many advantages: non-contact measurement: radar level meter does not need to contact with the material, avoiding the wear and pollution between the measurement equipment and the material, improving the service life and reliability of the equipment.
High-precision measurement: radar level meter has high measurement accuracy, and can accurately measure the level change of the material in the material tank. Wide temperature range adaptability: radar level meter usually has a wide range of temperature adaptability, and can work stably in high or low-temperature environments.
In the above pickling production process, by installing the radar level meter on the discharge box of the belt dryer, the operator can real-time and accurately monitor the level change of the material in the discharge box and understand the storage condition of the material, so as to adjust the operating parameters of the dryer in time.
Through the use of a radar level meter, it can realize the long-term monitoring, automatic control, and alarm function of the material level in the discharge box, and improve production efficiency and quality assurance.
In summary, as a high-precision, non-contact level measurement equipment, the radar level meter has an important measurement application in the discharge box of the belt dryer.
It can help operators monitor the level changes of materials in real time and accurately, improve production efficiency and management level, and further promote the development of chemical production and other industries.
