The utility model provides a following technical scheme: the utility model provides a DPF device that easy dismouting was maintained, includes DPF particle trap body, the outside cover of DPF particle trap body is equipped with down the body, the upper end of DPF particle trap body spanes through the connecting block and is connected with the handle, the upper end of body is connected with the upper tube body through the connecting piece down, fastening bolt is worn to be equipped with in one side of connecting piece, fastening bolt needs the cooperation nut to use, go up and seted up exhaust through-hole on the right side wall of body.

Preferably, the DPF particle trap body is in contact with, but not connected to, the lower pipe body.

Preferably, the nut is located on the underside of the connector.

Preferably, the handle is in an inverted U-shaped structure.

Preferably, the upper pipe body and the lower pipe body have the same diameter.

Compared with the prior art, the utility model discloses possess following beneficial effect:

the utility model discloses a set up body, lower body, handle, connecting piece, fastening bolt and nut, utilize the mutually supporting between them to can realize taking out from lower body when DPF particle trap body takes place to block up or the damaged condition, change new DPF particle trap body, equipment continues work, replaces the trap that gets off simultaneously and carries out regeneration treatment.
