A powder metallurgy tempering furnace

Abstract

The invention discloses a powder metallurgy tempering furnace. The powder metallurgy tempering furnace comprises a tempering furnace body. A feeding rack is arranged at a feeding inlet of the tempering furnace body, and a discharging rack is disposed at a discharging outlet of the tempering furnace body. The powder metallurgy tempering furnace further comprises a feeding inlet oil fume collecting chamber, a discharging outlet oil fume collecting chamber, an oil fume collecting header pipe and an incinerator, wherein one end of the feeding inlet oil fume collecting chamber is in through connection with the feeding inlet of the tempering furnace body; one end of the discharging outlet oil fume collecting chamber is in through connection with the discharging outlet of the tempering furnace body; one end of the oil fume collecting header pipe is in through connection with the feeding inlet oil fume collecting chamber through a feeding inlet oil fume collecting pipe, and the other end of the oil fume collecting header pipe is in through connection with the discharging outlet oil fume collecting chamber through a discharging outlet oil fume collecting pipe 7; and the incinerator is in through connection with the oil fume collecting header pipe. By means of the powder metallurgy tempering furnace provided by the invention, oil fume generated in the tempering process can be collected to the incinerator so that incineration disposal of the oil fume can be achieved, and environmental pollution caused by the tempering process is effectively reduced.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to a powder metallurgy tempering furnace. Background technique [0002] At this stage, with the maturity and development of powder metallurgy technology, more and more workpieces are gradually realizing powder metallurgy. Powder metallurgy parts will use lubricating oil in the pressing and forming process, and quenching oil will be used in the quenching process. Unlike non-powder metallurgy parts, due to the physical characteristics of powder metallurgy parts, it is difficult to remove most of the oil fume by cleaning and drying, which directly causes a large amount of oil fume to be generated during the heat treatment process. In the past, tempering furnaces suitable for heat treatment of non-powder metallurgy parts faced problems such as difficulty in collecting and disposing of oil fume, which directly led to excessive concentration of oil fume in the production workshop and s...

AI Technical Summary

Problems solved by technology

Different from non-powder metallurgy parts, due to the physical characteristics of powder metallurgy parts, it is difficult to remove most of the oil fume by cleaning and drying, which directly causes a large amount of oil fume to be generated during the heat treatment process.

In the past, tempering furnaces suitable for heat treatment of non-powder metallurgy parts faced problems such as difficulty in collecting and disposing of oily fume, which directly caused the concentration of oily fume in the production workshop to exceed the standard, seriously threatening the health of production personnel
