Operation principle：

The cylinder of drying machine can be divided into A cylinders and B cylinders in the course of work, wherein drying is filled with A cylinders and B cylinders Agent, if the mode of operation of A cylinders is absorption mode when starting, the mode of operation of B cylinders is regeneration mode.

Wherein A cylinders and B cylinders multiple row are arranged, and A cylinders and B cylinders upper end are communicated with epithelium healing, and lower end is communicated with downtake, lower channel Communicate with inlet chamber and discharge chamber, epithelium healing is communicated with outlet chamber.

The downtake that inlet chamber and discharge chamber are communicated with A cylinders and B cylinders simultaneously is communicated, by valve control component control inlet chamber with Unlatching and closure between discharge chamber, when carrying out absorption mode in A cylinders, valve control component close for stretching out state, that is, downtake with The connection of discharge chamber, opens the connection of inlet chamber and downtake, realizes air inlet, prevent aerofluxuss, specifically, cylinder stretches out, promotes Valve element on valve rod is moved downward, and the secondary sealing area of the second seal on valve element acts on the 4th sealing surface of air vent On, during motion, the conical surface by the 4th sealing surface realize valve element to the heart, make secondary sealing area and the 4th sealing surface accurate Really fit, in seal process, sealing ring can prevent downtake or the gas in discharge chamber by leaking in the securing member on valve element Go out, to realize good sealing, meanwhile, regeneration mode is carried out in B cylinders, valve control component is contraction state, that is, open downtake With the connection of discharge chamber, the connection of inlet chamber and downtake is closed, aerofluxuss is realized, is prevented air inlet, be specifically, cylinders retract, The valve element on valve rod is promoted to move upwards, the primary sealing area of the first seal on valve element acts on the 3rd sealing of air inlet On face, during motion, the conical surface by the 3rd sealing surface realize valve element to the heart, make primary sealing area and the 3rd sealing surface Accurately fit, in seal process, during sealing ring can prevent downtake or the gas in inlet chamber by the securing member on valve element Spill, to realize good sealing.

During work, the working condition of A cylinders and B cylinders switches in absorption mode and regeneration mode repeatedly.

It would be recognized by those skilled in the art that it is possible to make numerous accommodations to above description, so embodiment and attached Figure is intended merely to describe one or more particular implementations.

Although have been described above and describe being counted as example embodiment of the present utility model, those skilled in the art will be bright In vain, which can be variously modified and is replaced, without departing from spirit of the present utility model.Furthermore it is possible to make many repair Change so that particular case is fitted to religious doctrine of the present utility model, without departing from this utility model central concept described here. So, this utility model is not only restricted to specific embodiment disclosed here, but this utility model may also include belonging to this practicality All embodiments of new scope and its equivalent.
