Abstract

The invention relates to device and method for preparing a regenerated rubber sheet by continually cooling and mixing desulfurized rubber powder. The device comprises a continuous production line consisting of a rubber desulfurizing device with a hopper, a transition conveyer, a single-screw oxygen isolating cooling device, a sheet handpiece, a pair of compression rollers and a shearing device, wherein the discharging hole of the rubber desulfurizing device is connected with the feeding hole of the single-screw oxygen isolating cooling device through the transition conveyer; and the discharging hole of the single-screw oxygen isolating cooling device is connected with the feeding hole of the sheet handpiece. In the invention, a double-screw rubber desulfurizing device is meshed in the same direction, so that mixing is uniform and the energy consumption is low. The preparation method comprises the following process steps of: (a) desulfurizing; (b) conveying in an oxygen isolating way; (c) cooling and mixing in an oxygen isolating way; (d) sheeting; (e) pressing; and (f) cutting. Due to the adoption of the oxygen isolating conveying as well as oxygen isolating cooling and mixing, high-temperature oxidation of high-temperature desulfurizing rubber powder is prevented, the mechanical property of the regenerated rubber is improved, the production is continuous and safe, and no waste is discharged.

Description

technical field [0001] The invention relates to the technical field of waste rubber recycling devices and methods, in particular to a device and method for directly preparing recycled rubber sheets by continuously cooling and mixing desulfurized rubber powder. Background technique [0002] The recycling of waste rubber in my country mainly adopts chemical desulfurization technology to produce reclaimed rubber, which accounts for more than 90% of recycled waste rubber. This chemical desulfurization process is segmented and intermittent, especially the desulfurized rubber powder discharged from the desulfurization tank. The 2-3-way refining and tableting process produces serious secondary pollution during the production process, and the production environment is relatively poor. At present, the cooling of desulfurized rubber powder in China adopts an open type. Due to the high temperature of the discharged desulfurized rubber powder, generally above 200°C, open cooling is easy ...
