Abstract
The invention relates to an efficient cooling fan of a vacuum gas quenching furnace, which is a front side-blowing fan. According to the defects, the side blowing type is changed into the front blowing type, the fan is made into an umbrella shape, the middle part is provided with a tubular air suction opening, the pipe opening of the tubular air suction opening and the umbrella-shaped shell have a certain distance so as to ensure the flow of the wind, the umbrella-shaped shell and the tubular air suction opening are connected by a front blowing type impeller blade, and the front part of the fan is provided with a funnel type wind receiving opening so that the wind directly flows into the funnel and blows towards a workpiece.
Description
Technical field
The present invention is a kind of efficient cooling blower on the vacuum air quench oven, is a kind of cooling blower of heat treatment industry.
Technical background
Present vacuum furnace air cooling air cooler major part is the side blown type blower fan, and wind at first blows to the furnace wall and refluxes through the right angle and blow to barge board, blows to the main flow airduct again through the guide plate of barge board, blows to workpiece through nozzle again by the main flow airduct.Whole process is through multistage backflow bump and right-angle turning, and the wind of therefore real arrival workpiece is very weak, has influenced the rate of cooling of workpiece to a great extent.
Summary of the invention
The present invention mainly makes improvements for the rate of cooling that the flow velocity that improves wind and flow improve workpiece, it mainly changes the blower fan of former side blown type into umbellate form fore blow formula, the centre is an air sucking mouth, inhaling between mouthpiece and shell is fore blow formula impeller blade, the one funneling mouth of giving a dinner for a visitor from afar is installed in the front of blower fan, wind is directly entered in the buccal funnel of giving a dinner for a visitor from afar, avoided former wind bump furnace wall to reflux, blow to guide plate then and reflux again and enter air main.The flow and the flow velocity of wind have been improved.
Concrete implementing method
Change blower fan into the umbellate form shape, can select suitable thick steel plate to make according to the different type of furnaces, the centre is the air sucking mouth of a tubulose, and its bore determines according to the flow of wind that also tubulose air sucking mouth and umbrella shell should have certain distance to guarantee the flow of wind.Be connected by fore blow formula impeller blade between umbrella shell and the tubulose air sucking mouth.The front of blower fan is that the funneling one's intention as revealed in what one says of giving a dinner for a visitor from afar flows directly into funnel and inwardly directly blows to workpiece.
Claims (2)
1. make principle streaming blower fan into umbellate form fore blow formula, the major character of blower fan is that shell is the umbellate form shape, and the centre is an air sucking mouth, is fore blow formula impeller between air sucking mouth and shell.
2. a funneling mouth of giving a dinner for a visitor from afar is installed in the front of blower fan, wind is directly entered in the buccal funnel of giving a dinner for a visitor from afar, avoided former wind bump furnace wall to reflux, blow to guide plate then and reflux again and enter air main.
