A waste tire fine rubber powder classifier

Abstract

The invention relates to the technical field of resource recycling comprehensive utilization and in particular relates to a waste tire refined rubber powder grader. The waste tire refined rubber powder grader is characterized by comprising a collecting tank, a spiral air inlet channel assembly, a dividing apron board, a barrel, a highly refined rubber powder cabin, a refined rubber powder cabin, a refined circumferential sieve cage, a highly refined circumferential sieve cage, a cyclone separator, a back blowing port, a cross balancing fin and an elastic rod. As a matched device of grinding constant temperature waste tire rubber powder, process production processes such as cooling, sorting, conveying and separation of rubber powder are finished. The device is operated in a closed environment, so that the environmental pollution is avoided, and the waste tire refined rubber powder grader is relatively low and the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of resource recycling and comprehensive utilization, in particular to a waste tire fine rubber powder classifier. Background technique [0002] At present, one of the recycling and comprehensive utilization methods of waste tire rubber is to prepare fine rubber powder, which is usually prepared by crushing at room temperature and has formed a large-scale industrial production. Raw materials, waste tire fine rubber powder (60-100 mesh) is an important additive, adding it to general rubber products can replace raw rubber up to 90%, and at the same time can improve the aging resistance of rubber products; also in tire products In the formula, 60-mesh waste tire fine rubber powder can replace 10-20% of the original rubber, and can also improve its wear resistance, prolong the service life of the tire, and greatly reduce the cost of the tire. However, the particulate matter and noise environmental pollution and ...

Problems solved by technology

[0003] The technical solution proposed in prior art 1 is to use screens of different specifications to screen fine rubber powder with different meshes at the same time, use a drive motor and an eccentric pulley as the power source of the vibrating screen, and use four side plates to form a closed device to solve the problem of fine rubber powder. Rubber powder particle pollution, but the dust-proof seal of the inlet and outlet of the vibrating screen is difficult to solve. The dust-proof seals currently used, such as elastic bellows or nylon braided sleeves, are easily damaged and cause fine rubber powder particles to escape and cause environmental pollution. The noise of vibrating screens is generally as high as 100dB(A), which not only causes environmental noise pollution, but also is an occupational hazard factor for operators. In addition, vibrating screens are originally one of high energy-consuming equipment; prior art 2 uses classifiers, cyclones Separators, sealing covers and other devices are used to improve the production efficiency of fine rubber powder, realize large-scale production, and reduce dust emissions, but no technical details are disclosed
