A preheating furnace heat dissipation plate

Abstract

The utility model discloses a preheating furnace radiating plate relates to spinning assembly preheating technical field, and its technical scheme main points are: including radiating plate main part, be provided with the chute in radiating plate main part, be provided with the adjusting plate in the chute and slide, be provided with a plurality of through -hole of setting of radiating plate main part on radiating plate main part, be provided with the adjusting hole of corresponding with through -hole one one on adjusting plate, the upper end rotationally connected of radiating plate main part has the cover, be provided with the heat conduction net in radiating plate main part. The utility model discloses through the sliding of adjusting plate, can adjust the flow area of through -hole and adjusting hole, when just preheating spinning assembly, through the sliding adjusting plate makes the flow area of through -hole and adjusting hole gradually increase, and then makes the preheating effect of spinning assembly more, will not cause the spinning assembly damage because of the high temperature of suddenly, the cover can reflect steam to the top and the side of spinning assembly can be heated, makes the spinning assembly preheating more uniform.
