Problems solved by technology

There are countless tiny holes in the DPF of this structure. With the use of the DPF, these tiny holes will be blocked by PM, and part of the PM will be oxidized and burned when the vehicle is running. With the increase of the working time of the DPF, such a method It is becoming more and more difficult to regenerate, and the DPF is seriously blocked and the exhaust gas cannot be discharged. At this time, a device that can clean the DPF is needed to dredge the tiny pores in the DPF

Abstract

The invention provides a DPF (Diesel Particulate Filter) installing frame of a DPF cleaning device. The DPF cleaning device comprises a container and a cover used for sealing the container. The DPF installing frame comprises a locking mechanism and an installing frame baseplate, wherein a through hole communicated with a DPF hole channel is formed in the installing frame baseplate; the installingframe baseplate is connected to and fixed to the inner wall of the container in a sealing manner; the locking mechanism is connected to and fixed to the installing frame baseplate or the container; the locking mechanism is used for squeezing a PDF to be connected to and fixed to the installing frame baseplate in a sealing manner; a sealing adjusting plate is arranged between the DPF and the installing frame baseplate; the locking mechanism is connected to and fixed to the installing frame baseplate; when the container contains the DPF, the container is divided into a first cavity and a secondcavity by the DPF; the first cavity is used for being connected to a high pressure air source; and the second cavity is used for being connected to atmosphere by an air blast quick opening valve.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a DPF installation frame of a DPF cleaning device. Background technique [0002] DPF, Diesel Particulate Filter diesel particulate filter refers to a device installed in the exhaust system of a diesel vehicle to reduce particulate matter (PM) in the exhaust by filtering, referred to as DPF. DPF can effectively purify 70% - 90% of the particles in the exhaust gas, and is one of the most effective and direct methods to purify diesel engine particulate matter. It has been commercialized internationally. The DPF is installed on the exhaust pipe of the diesel engine. When the exhaust gas passes through, the PM is adsorbed and filtered by the filter element. However, as the working time increases, the PM inside the filter element increases, resulting in an increase in the exhaust back pressure, which will affect the power and economy of the diesel engine. Removing PM from the filter eleme...
