Abstract

The invention discloses a production line for desulfurization, mixing and calendering of recycled rubber. The production line involves a desulfurization tank, a cooling cylinder, a cooling tank, a rubber powder storage bin, a mixing machine, a calender, a morming machine, and a discharging and cooling conveying device which are sequentially connected, wherein the desulfurization tank is connectedwith the cooling cylinder through a conveying device A, the cooling cylinder is connected with the cooling tank through a conveying device B, the cooling tank is connected with the rubber powder storage bin through a conveying device C, the bottom of the rubber powder storage bin is connected with the mixing machine through a conveying device D, the mixing machine is connected with the calender through a conveying device E, the discharging port of the forming machine is connected with the discharging and cooling conveying device through a conveying device F, and the side, away from the discharging and cooling conveying device, of the discharging port of the forming machine is connected with the conveying device E through a leftover material conveying device. From the above structure, the production line for desulfurization, mixing and calendering of the recycled rubber realizes full-automatic desulfurization, cooling, mixing and calendering forming of the recycled rubber, fully utilizes waste gas and leftover materials, reduces the production cost and saves the energy consumption.

Description

technical field [0001] The invention relates to the technical field of a recycled rubber production line, in particular to a recycled rubber desulfurization, mixing and calendering production line. 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 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 to oxidize the desulfurized rubber powder, and even generate open flames, ...

Problems solved by technology

[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 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 to oxidize the desulfurized rubber powder, and even generate open flames, which affects the performance of reclaimed rubber; They all adopt the process of rubber mixing and sheeting with an open mill. On the one hand, there is secondary pollution, and secondly, there are hidden safety problems for operators. Therefore, it is the green waste rubber to solve the problems of oxygen-proof cooling of desulfurized rubber powder and green production of reclaimed rubber. Recycling and Utilization of Key Process Technologies

[0003] At present, there are also some processes on the market to produce reclaimed rubber after desulfurization, cooling, and mixing of recycled rubber (such as the technical solution recorded in the publication number CN102344592B), but the energy consumption in the production process is relatively high, although recycled rubber has been used , but the profit of the company is still not too high, and some companies even have to rely on the local government's subsidies for recycled rubber to maintain production
