Connecting structure and connecting method for parts at thin plate of atomizing and cooling dust remover

Abstract

The invention discloses a connecting structure for parts at a thin plate of an atomizing and cooling dust remover. A rivet nut and a rivet screw are included, and the parts at the thin plate comprisea valve mounting flange, an inspection door plate, a sprayer mounting seat and an observation glass window mounting flange. The parts at the thin plate and the thin plate at the joint are provided with matched regular hexagonal through holes and matched regular circular through holes. The rivet nut comprises an internal thread section, a bent part and a flat flange. The rivet screw comprises an external thread section, a smooth cylindrical section and a screw cap, and the smooth cylindrical section is in cup joint with a boss ring and a sealing ring. A hexagonal groove and a sealing rubber layer are arranged on the top end surface of the sprayer mounting seat, a threaded groove is formed in the bottom of the hexagonal groove, and a hexagonal stainless steel sheet is arranged above the sprayer mounting seat. The invention further provides a corresponding connecting method. Installation of parts at all thin plates is simplified into the process that the two thin plates with the regular hexagonal through holes and the regular circular through holes are installed and fastened through rivet nuts and rivet screws, the installation efficiency is improved, the installation structure is attractive, and the sealing performance is good.

Description

technical field [0001] The invention relates to the technical field of installation of dust collector accessories, in particular to a connection structure and a connection method of components at the thin plate of a spray cooling dust collector. Background technique [0002] At present, the combination of spray cooling and dust removal is used for the treatment of diesel engine exhaust, which requires a large number of welding nuts to fix small parts. Because the overall plate is relatively thin, a large area of ​​serious deformation is caused during the welding process; The shift of the center position of the machine will bring great difficulties to the subsequent assembly and also bring inconvenience to the later maintenance. [0003] In addition, during the use of the dust collector, due to the pressure requirement, it is necessary to ensure the absolute sealing of the joints of the components. If ordinary screws and nuts are used to install the components on the thinner ...

Problems solved by technology

[0002] At present, the combination of spray cooling and dust removal is used for the treatment of diesel engine exhaust, which requires a large number of welding nuts to fix small parts. Because the overall plate is relatively thin, a large area of ​​serious deformation is caused during the welding process; The shift of the center position will bring great difficulties to the subsequent assembly and also bring inconvenience to the later maintenance.

[0003] In addition, during the use of the dust collector, due to the pressure requirement, it is necessary to ensure the absolute sealing of the joints of the components. If ordinary screws and nuts are used to install the components on the thinner plate of the current dust collector, it will cause problems in mechanical properties and sealing. waiting to be solved
