Description
Technical Field
The utility model relates to a printing and dyeing mechanical equipment field especially relates to a circulating air cooling device.
Background
The fabric needs to be cooled after the gravure printing and drying process, a common air cooling device comprises a refrigeration air conditioner, a cold air box, a box body, a conical air pipe, an axial flow fan, air blowing boxes, a cloth discharging rack, a cloth discharging traction roller, a cloth guide roller and a swinging cloth discharging device, wherein the box body is arranged on two sides of the cold air box provided with the refrigeration air conditioner, the inner cavity of the cold air box is communicated with the inner cavity of the box body, the conical air pipe provided with the axial flow fan at the lower end is arranged in the box body, a plurality of air blowing boxes are vertically arranged and penetrate through the inner side panel of the box body to be connected and communicated with the conical air pipe, and a fabric channel is formed between every two adjacent air blowing boxes. During operation, cold air generated by the refrigeration air conditioner is sucked into the conical air pipe by the suction of the axial flow fans in the boxes on the two sides of the cold air box, enters the blowing air box from the two ends and is uniformly sprayed out from the blowing openings on the upper surface and the lower surface of the blowing air box to realize cooling of the fabric. However, cold air escapes to the periphery after cooling, the utilization rate of the cold air is low, and the cold air escapes to a subsequent printing process and can take away moisture on a printing net, so that the subsequent printing has the problem of dry net.
Disclosure of Invention
An object of the utility model is to provide a circulation forced air cooling device.
Realize the utility model discloses the technical scheme of purpose is: a circulating air cooling device comprises a heat insulation fan cover which is arranged above a guide belt and only provided with an opening at the bottom, at least one group of circulating fans are arranged in the heat insulation fan cover, an air box is arranged at the bottom of the heat insulation fan cover, each group of circulating fans are communicated with the air box through an air pipe, air nozzles are arranged at the bottom of the air box at equal intervals, and air outlets of the air nozzles face the surface of the guide belt; the heat insulation fan cover is characterized in that a partition plate is transversely installed between the air box and the circulating fan inside the heat insulation fan cover, an air inlet area is arranged below the partition plate, a closed cold air area is arranged above the partition plate, a refrigerator is installed between the cold air area and the air inlet area, an air inlet at the bottom of the refrigerator is communicated with the air inlet area, and an air outlet at the top of the refrigerator is communicated with an air inlet of the circulating fan in the cold air area.
Furthermore, two groups of circulating fans are arranged on any two pairs of sides of the top of the heat insulation fan housing.
The utility model discloses circulating fan makes the cold wind district produce the negative pressure and inhales the air in air inlet district into the cold wind district after the refrigerator cools off, and the air of refrigerated air is again through the tuber pipe injection bellows through circulating fan's air intake, and along with the cooling air constantly injects into, the air pressure in the bellows increases, and the cooling air just spouts the substrate through the tuyere that spouts of bellows; air after cooling the substrate is sucked by the air inlet area from all around, and is sucked into the cold air area through the refrigerator, realizes cold air cyclic utilization like this, prevents effectively that cold air from escaping, improves substrate cooling effect, also avoids simultaneously that wind blows to cause on the printing net to dry the net.
