A new generation“Self-cleaning”

Regenerate the drying drum

PracticeThe verification effect is good

○ Good technology can stand the test. ○

At present, China's highway industry is in the maintenance stage.，A large amount of waste asphalt mixture to be used，Deji Machinery has been focusing on continuous research and development in the field of regeneration.，With the new structural design and the addition of“Self-cleaning”Function of a new generation of downstream drying drum（Patent No：ZL 2023 2 1077475.1）Launch into the market，It is also used in a full range of Deji mechanical recycling asphalt mixture mixing equipment.，Its effect in the market is well received.。

An ordinary downstream drying drum can heat the recycled material to a temperature equivalent to that of the new aggregate，This greatly increases the proportion of the hot recycled material added to the mixture，Even in many parts of the country to achieve 100.%Production of thermal regeneration。And the new generation of downstream“Self-cleaning”Drying drumIt can not only ensure that the heating temperature of recycled materials is close to 160℃，Even more than 160℃，But also effectively controls the problem that the tail gas temperature is too high.，A set from Xi'anDGRFrom the field measurement effect of the equipment，Measured temperature at discharge 156.5℃，The measured temperature of the flue reached 157.℃，Almost no temperature difference。

It is even more remarkable that，A new generation of downstream“Self-cleaning”The drying drum has been introduced to the market and applied to the whole series of products of Deji Machinery.，Nearly 20 sets of equipment have entered the market.，So far，In the past, there was a problem in the industry that the material was stuck inside the regenerative drying drum.、Fire inside the drum due to high exhaust temperature，In the new generation of downstream“Self-cleaning”Never occurs on the drying drum。Even so，In line with“Although it hasn't happened yet.，But not without prevention”The concept of preventive measures，We still add a material shortage alarm device at the feeding front end of the drying drum.，Further prevent the hidden danger of fire caused by the temperature rise inside the roller in a short time due to the lack of material，At the same time, a one-key fire emergency treatment button is added.，Shorten operator response times，Make it respond quickly，Avoid all kinds of unknown hidden dangers.，Cause irreversible damage to the equipment，Thereby harming the interests of users.。

In addition，To ensure the temperature of the mixture，In the past, the insufficient temperature of recycled materials was neutralized by raising the heating temperature of new aggregates.，So as to achieve the purpose that the final mixture temperature meets the use requirements.，This undoubtedly increases energy consumption.，Wasted unnecessary costs。And this problem flows downstream in the new generation.“Self-cleaning”The drying drum is easily solved，Received unanimous praise from the market。

The downstream drying drum has the following advantages：

The dedusting flue port is arranged at the discharge end of the roller，Regenerated fine material feed is not easily pumped away by the air duct；

Brand-new structural design，O that the regenerated material can continuously form a uniform material curtain.，And that thermal efficiency is improve；

The parallel flow heating can effectively reduce the problems of asphalt aging and rake tooth sticking caused by heating the recycled material from the low temperature zone to the high temperature zone.；

Simpler control system，Convenient and easy to operate；

The overall cost of equipment and the cost of later maintenance are lower.。

True gold fears no fire.，Good technology can stand the test.。Except for the new generation of downstream“Self-cleaning”Drying drum，In the field of regeneration, we also have a regeneration additive system.、Conventional plant-mix hot regeneration、Continuous cold in-plant recycling technology，Can not only provide a complete set of equipment，It can also meet the equipment transformation of most brands and models at present.，Provide a total solution。The market needs it，Deji will continue to develop and create.！
