Polyurethane flexible foam continuous powdering device and powdering method thereof

Abstract

The invention discloses a polyurethane flexible foam continuous powdering device and a powdering method thereof. The device comprises a conveying and feeding module, a first-section mechanical shearing and powdering module, a second-section mechanical shearing and powdering module and a powder collecting module which are communicated in sequence, the feeding module is used for conveying polyurethane flexible foam waste into the first-section mechanical shearing and powdering module, and the first-section mechanical shearing and powdering module and the second-section mechanical shearing and powdering module are each provided with a cooling system. The invention further provides a powdering method based on the device, the temperature can be controlled in the powdering process, the powdering effect is good, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of polyurethane soft foam pulverization, in particular to a polyurethane soft foam continuous pulverization device and a pulverization method thereof. Background technique [0002] Polyurethane foam is made of isocyanate and hydroxyl compound through polymerization and foaming. According to its hardness, it can be divided into two types: soft and hard. Polyurethane soft foam is widely used in industries such as car seats and furniture because of its excellent performance. , as the use of polyurethane soft foam increases year by year, the amount of polyurethane soft foam waste is also increasing year by year. Polyurethane waste is difficult to degrade naturally, so how to initially crush polyurethane waste is particularly important. At the same time, since the end of last century , with the strengthening of people's awareness of environmental protection and environmental protection regulations, people not onl...

Problems solved by technology

It discloses a solid waste polyurethane foam crusher, which can screen qualified materials through a screen, and unqualified materials can be crushed repeatedly, which ensures the crushing effect and improves the crushing efficiency, but the polyurethane crushing process generates severe heat. Difficult to control, the pure shearing method will lead to non-selective chain scission, resulting in the inactivation of the prepared particles and the decline of application performance
