Application method for classifier of waste tire fine rubber powder

Abstract

The invention relates to the technical field of cyclic and comprehensive utilization of resources, in particular to an application method for a classifier of waste tire fine rubber powder. The application method is characterized in that cross-shaped balance fins face airflow in a barrel body and pressure, caused by the airflow, on paddles of the cross-shaped balance fins is transformed into a driving moment of the paddles to drive the paddles to rotate; elastic rods are used for restricting and the paddles of the cross-shaped balance fins only can do reciprocating swinging to a certain extent along a rotary circumferential plane, so that the elastic rods are pulled to generate periodic tensile deformation; mechanical vibration generated by the elastic rods is conducted to circumferential screen cages connected with two ends of the elastic rods and waste tire rubber particles which block sieve hole meshes can be cleaned; the classifier is used as a matched device of a steam protection mill and is used for finishing a technological production process including rubber powder cooling, sorting, conveying, separation and the like; and the device is operated in a closed manner, so that the environment pollution is avoided, the energy consumption is relatively low and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of resource recycling and comprehensive utilization, in particular to a method for using 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 environme...

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
