Tail gas dust removal device for engineering machinery

Abstract

The invention provides a tail gas dust removal device for engineering machinery. The device comprises a box body, a gas inlet pipe and a gas outlet pipe are respectively arranged on the two sides of the box body, two supporting frames are obliquely arranged in the box body, filter screens are fixedly arranged in the supporting frames, dust collecting hoppers are arranged below the filter screens, covers are installed at the bottoms of the dust collecting hoppers in a threaded mode, and connecting blocks are fixedly installed at the tops of the supporting frames. Two mounting holes are formed in the top of the box body, pressing blocks are arranged in the mounting holes and make contact with the connecting blocks, cover plates are arranged at the tops of the pressing blocks, and the cover plates are fixedly connected with the box body. A protective cover fixedly connected with the box body is arranged below the gas outlet pipe, and a vibration mechanism is installed in the protective cover. The tail gas dust removal device is convenient to use, tail gas of engineering machinery can be filtered, particles in the tail gas can be treated in a centralized mode, and meanwhile the filter screens can be replaced quickly.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to an exhaust dust removal device for construction machinery. Background technique [0002] Construction machinery is an important part of the equipment industry. In a nutshell, all the mechanical equipment necessary for comprehensive mechanized construction projects required for earthwork construction projects, road surface construction and maintenance, mobile lifting and loading and unloading operations, and various construction projects are called construction machinery. [0003] During the use of construction machinery, a lot of exhaust gas is often discharged, which not only causes environmental pollution, but also seriously affects people's health. Therefore, an exhaust dust removal device for construction machinery is proposed. Contents of the invention [0004] In order to overcome the problems existing in the prior art that exhaust gas pollutes the environ...
