Description

A desulfurization device for secondary processing of renewable resources

technical field

The utility model relates to the technical field of rubber desulfurization, in particular to a desulfurization device for secondary processing of renewable resources.

Background technique

Desulfurization is a key section in the reclaimed rubber production process, which is directly related to the quality of the reclaimed rubber products. The so-called desulfurization is not to separate the bound sulfur in the vulcanized rubber, but to break the sulfur bonds in the elastic network structure to restore the plasticity of the vulcanized rubber. As the main resource for producing reclaimed rubber, rubber powder is fluffy and has no adhesiveness before desulfurization. Only the desulfurized rubber powder has plasticity and can be bonded together. The desulfurized rubber powder is then passed through. The reclaimed rubber block is obtained by the rolling of the refiner and the open mill, and the meaning of the desulfurization of the reclaimed rubber lies in this.

After extensive search, it was found that the typical desulfurization device for processing in the prior art, such as a desulfurization device for recycled rubber production and processing disclosed in publication number CN211057011U, can be used in conjunction with a movable plate and a handle block, and can be adjusted by adjusting the movable plate. The position in the horizontal direction can adjust the feeding speed of the main body of the feeding hopper, and after the feeding is completed, it can be blocked by the movable plate to prevent foreign objects from entering the inside of the device.

In the process of devulcanization of rubber, it is necessary to input steam into the desulfurization tank and heat the rubber powder to achieve the purpose of desulfurization. However, due to the insufficient and uniform contact of the rubber powder in the existing desulfurization tank with the steam, the desulfurization efficiency of the rubber powder is reduced.
