Description

technical field

[0001] The invention relates to a polyurethane multifunctional high-pressure mixing head device. Background technique

[0002] Polyurethane waste recycling technology uses polyurethane waste to be processed into powder or granules to complete the regeneration operation. It is necessary to use a mixing device to process the material into powder or granules for transportation and spraying, so as to avoid the degradation of the processing performance of the processing components on the material, but at present The mixing device for mixing polyurethane and solid materials has complex structure, poor mixing uniformity and low mixing efficiency, and is not suitable for industrial application.

[0003] The Chinese patent "mixing core, a mixing device using it to mix polyurethane and solid materials" with application number 201811290823.7 discloses a mixing device, including spray gun parts for polyurethane spraying and horizontal arrangement, solid materials falling...
