Cylindrical double-wall bellows cooling device

Abstract

The invention provides a cylindrical double-wall bellows cooling device. The cylindrical double-wall bellows cooling device is arranged at an outlet of a molding mold and comprises a cylindrical cooling chamber, the cylindrical cooling chamber comprises two side walls with arc cross sections and a water receiving tank, one end of each one of the two side walls is hinged to a long side of the water receiving tank, the other end of each one of the two side walls is provided with a matching locking device, the inner surface of the side wall is uniformly provided with water injection nozzles and gas injection nozzles, the water injection nozzles are orderly connected to a water outlet valve, a water outlet pump and a water source by pipes, the gas injection nozzles are orderly connected to a gas outlet valve and a gas source by pipes, the bottom of the water receiving tank is provided with an opening, the opening is orderly connected to a water return pump and a filtration device by pipes, and the filtration device is connected to the water source. The cylindrical double-wall bellows cooling device can improve a cooling area, improve cooling efficiency and save water resource.

Description

technical field [0001] The invention belongs to the field of manufacturing double-wall corrugated pipes, and in particular relates to a cooling device for double-wall corrugated pipes. Background technique [0002] At present, in the production of double-wall corrugated pipes, due to the high temperature of the forming mold module, the rejection rate will be too high. Some machines have a built-in small fan or add air duct cooling to cool the forming mold module, but the cooling effect is not obvious, and it has little effect on increasing the forming speed. In the prior art, there is a ring-shaped cooling device installed at the outlet of the mold. A water jet is installed inside the ring to cool the double-wall bellows through the sprayed water. However, the cooling area of ​​this device is limited. And the water receiving tank is separated from the cooling device, and the sprayed water is easy to leak, which wastes water resources.
