Exhaust purifier

Abstract

The invention provides an exhaust purifier. The exhaust purifier comprises a shell and a pushing and pressing piece, wherein one end of the shell is open, the other end of the shell is sealed, a position clamping hole is formed in the sealed end of the shell, and the pushing and pressing piece can get into and out the shell from the position clamping hole; a first filter plate and a second filterplate are arranged in the shell, and a guide rail and a movable plate which can slide along the guide rail are arranged on the inner wall of the shell; an air hole is formed in the movable plate, oneend of the movable plate is connected with the pushing and pressing piece, a deashing rod corresponding to the air hole is arranged at the other end of the movable plate, the deashing rod contains a cavity inside and is communicated with the air hole, and a slotted hole is formed in the side wall of the deashing rod; and filtration pores corresponding to the deashing rod are respectively formed inthe first filter plate and the second filter plate, and a reset spring is also arranged on the movable plate. The exhaust purifier provided by the invention is novel and detachable in structure, andinternal parts can be cleaned or replaced; and an internal filter element can be cleaned to some extent without detaching the exhaust purifier, dust and particles which are accumulated on the filter element are reduced, and the phenomenon that exhaust treatment is not good enough or exhausting is not smooth as the filter element is blocked are avoided.

Description

technical field [0001] The invention relates to the field of exhaust gas purification, and more specifically, to an exhaust gas purifier. Background technique [0002] Diesel engine has the characteristics of high thermal efficiency, high power, good economy and reliability, and has been widely used in the field of construction machinery, such as: road rollers, loaders and excavators are powered by diesel, although diesel engines have many Advantages, but there are many harmful components in the exhaust gas, mainly carbon dioxide, oxynitride, small molecular organic matter and carbon particles, etc. The discharge of these harmful substances has greatly endangered the health of construction workers and the normal progress of construction. However, the existing exhaust gas purification device is not easy to install, disassemble and clean. After long-term use, it is easy to cause particle dust to accumulate and block the filter element, resulting in failure to perform normal ex...

[0002] Diesel engine has the characteristics of high thermal efficiency, high power, good economy and reliability, and has been widely used in the field of construction machinery, such as: road rollers, loaders and excavators are powered by diesel, although diesel engines have many Advantages, but there are many harmful components in the exhaust gas, mainly carbon dioxide, oxynitride, small molecular organic matter and carbon particles, etc. The discharge of these harmful substances has greatly endangered the health of construction workers and the normal progress of construction. ; However, the existing exhaust gas purification device is not easy to install, disassemble and clean. After long-term use, it is easy to cause particle dust to accumulate and block the filter element, resulting in the failure of normal exhaust gas treatment and even affecting the exhaust.
