The principle of equipment for point heating and drying

Motors, electromagnets, welding machines, etc. are all inductive equipment, power capacitors, compensation capacitors are capacitive equipment, water heaters are resistance equipment, and induction cookers are inductive equipment.

Hello landlord, the drum scraper dryer is a continuous operation equipment that dries the liquid phase material or ribbon material attached to the outer wall of the cylinder by means of heat conduction through a rotating cylinder. The material liquid to be dried flows into the receiving tank of the drum dryer from the high tank. The drying drum is driven by the transmission device and rotates according to the specified speed.

The material is formed by the film distribution device on the wall of the drum. The heating medium is continuously passed into the cylinder, the cylinder is heated, the wet vaporization of the material film is vaporized by the heat transfer of the cylinder wall, and then the material that meets the drying requirements is scraped off by the scraper, and is transported to the storage tank through the spiral for packaging. The wet matter removed by evaporation can be introduced into the corresponding treatment device through the closed cover according to its nature; It is usually water vapor, which can be released directly into the atmosphere from the exhaust pipe at the top of the hood.

The machine is mainly used to process liquid materials, which can be heated and dried by steam, hot water or hot oil, and can be cooled by cold water. Reference.

How does a drum scraper dryer work? Trouble to give a detailed introduction....5665

The drying tower is the dry finch Li take, you can build a library to find the disturbance.

Use a centrifuge to dehydrate and then dry, saving energy.

With my drying equipment, there is no need for solid-liquid separation, just dry directly.

Drying oven is the equipment that most industries need to use, mainly for the drying treatment of production equipment, and is also divided into many types, vacuum drying oven is one of them, its drying method is relatively old, but it is relatively reliable and safe, and fast, mainly used in medical treatment, scientific research, today I will introduce you to the vacuum drying oven, including its ** comparison and the introduction of the use method, interested friends may wish to come to understand, I hope to bring you some reference.

1. Vacuum drying oven**:

1.Product type: Pinggang 2017**FZG series vacuum.

Brand: Pinggang.

2.Product type: ATEL DZF-6090 vacuum drying oven.

Brand: Atel.

3.Product type: Vacuum drying oven Shanghai Jicheng GDW2005

Brand: Shanghai Jicheng.

2. Steps for the use of vacuum drying oven:

1. Put the items that need to be dried into the vacuum drying oven, close the door of the box, close the air release valve, open the vacuum valve, turn on the vacuum pump power supply and start pumping, so that when the vacuum degree in the box is reached, close the vacuum valve, and then turn off the vacuum pump power supply.

2. Turn the power switch of the vacuum drying oven to the "on" place, select the required set temperature, the temperature in the box begins to rise, when the temperature in the box is close to the set temperature, the heating indicator light flashes on and off, repeats many times, generally within 120min can enter the constant temperature state.

3. When the required working temperature is low, the second setting method can be adopted, such as the required temperature of 60, the first time can be set to 50, and the second time to set 60 after the temperature overshoot begins to fall. In this way, the temperature overshoot phenomenon can be reduced or even eliminated, and the constant temperature can be entered as soon as possible.

4. According to the humidity of different items, choose different drying times, such as the drying time is longer, the vacuum degree drops, and it is necessary to pump again to restore the vacuum degree, the vacuum pump power supply should be turned on first, and then the vacuum valve should be opened.

5. After drying, the power supply of the drying oven should be turned off, the air release valve should be opened, the vacuum state in the box should be lifted, and then the door should be opened to take out the items. After the vacuum is lifted, if the sealing ring and the glass door are tightened and deformed, it is not easy to open the door immediately, and after a period of time, the sealing ring can be easily opened after the sealing ring returns to its original shape.

Note: The vacuum chamber housing must be effectively grounded to ensure safe use. When continuous pumping is not required, the vacuum valve should be closed first, and then the power supply of the vacuum pump should be turned off, otherwise the vacuum pump oil should be poured into the box.

If the disposed of flammable items is disposed of, the temperature must be cooled below the ignition point before it can be put into the air, so as to avoid oxidation reaction and combustion. Do not put explosive materials to dry.

The above is for you to introduce the vacuum drying oven ** comparison and the correct way to use, I believe we all understand, vacuum drying oven is a precision instrument, in the process of use must pay attention to the correct operation methods and specifications, as well as its maintenance is also need to pay attention to, frequent cleaning and wiping is essential, and finally here to remind everyone, when buying a vacuum drying oven, we must carefully select, shop around, do not buy inferior vacuum drying oven because of greed for cheap.

Reliable performance is reported. **Years.

Syria is located in the western part of the Asian continent, on the east coast of the Mediterranean Sea, bordered by Turkey to the north, Iraq to the southeast, Jordan to the south, Lebanon and Palestine to the southwest, and Cyprus across the sea to the west.

The most intolerable thing in Syria is the dryness and sweltering heat, and the cities of Syria are as dry and sweltering as if they were in a steamer; You'll need a lot of hydration in the city, but you'll still be sweating it out. The people of this city, one by one, have chapped lips and are dark, which is the result of being evenly exposed to the sun.

Nature.

The climate of Syricia is relatively dry, blocked by high mountains, and three-fifths of the area receives less than 25 cm of rainfall per year. zhi (precipitation is sparse and scarce).

The coastal and northern regions of the country have a Mediterranean climate, with hot and dry summers and mild and rainy winters. The southern region has a tropical desert climate, with high temperature and drought throughout the year, and precipitation is scarce. Grasslands and deserts account for more than half of the country's area.

Humanities

The country is a middle-income country, located in the center of the Middle East, the world's most oil-and-gas richest country, with an economy dominated by agriculture, petroleum, processing industries (such as phosphate processing) and tourism, and oil resources are facing depletion, population growth is too fast, and unemployment is gradually increasing.

And it still happens that the repeated method is not right, the included content filter, the filter subscription, the dysfunction is handy, and the ground is down-to-earth.

Syria comes.

The most unbearable thing is dryness and stuffiness.

Self-heating. The whole city was as dry as if it was covered by an airtight fiberglass. The people were there, their lips were chapped, and the water they drank immediately turned into strings of sweat, dripping down their foreheads and drooping down the leaves.

The climate in Syria is really dry and muggy!

Expand on it yourself, there's nothing I can do.

Syria comes.

The climate is relatively dry, and the source is blocked by high mountains, and three-fifths of the area of Bai receives less than 25 cm of rainfall throughout the year. The coastal and northern regions of the country have a Mediterranean climate, with hot and dry summers and mild and rainy winters, with different periods of rain and heat; The southern region has a tropical desert climate, with high temperature and drought throughout the year, and precipitation is scarce. Grasslands and deserts account for more than half of the country's area.
