A sorting device for fine rubber powder finished products of waste tires

Abstract

The invention relates to the technical field of resource recycling and comprehensive utilization, in particular to a finishing device for fine rubber powder finished products of waste tires. It is characterized in that it includes an air box pulse bag capture assembly, a spiral stepped blade separation assembly, and a turntable assembly. The technical scheme of separating steam by pulse air bag and trapping rubber powder particles is adopted. At the same time, combined with the technology of cyclone separation and sedimentation separation, a spiral stepped blade is designed. The rubber powder particles are constantly in contact with the spiral during the process of spiraling up the inner wall of the cylinder. The impact of the stepped blades and the friction of the inner wall of the cylinder lose energy and fall to the turntable, while the steam is discharged through the filter bag along the channel of the spiral stepped blades, so as to efficiently complete the goal of separating and trapping rubber powder particles.

Description

technical field [0001] The invention relates to the technical field of resource recycling and comprehensive utilization, in particular to a finishing device for fine rubber powder finished products of waste tires. 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. The waste tire fine rubber powder prod...

Problems solved by technology

[0003] The technical solution proposed in prior art 1 is to use the PLC control system and the pusher plate to complete the material collection and arrangement process, but it does not solve the problem that the rubber powder accumulation is not easy to dissipate heat and cause the rubber powder product to store heat and spontaneously ignite at room temperature and the environmental protection problem; the existing Technology 2 uses a drying device, a screening device and a coating device to complete the drying, granulation, and packaging process of the finished product. However, since the material is fertilizer granules, the particle diameter can be increased by granulation. Steam is heated to remove moisture, and then the steam and material are separated through a screen

If it is applied to this technical field to solve the problem of heat storage and spontaneous combustion of rubber powder products, it is not suitable. First, the surface of the rubber powder crushed by mechanical shearing is uneven and has short branches, which are very easy to gather and accumulate heat, and can be used as raw rubber It is not easy to disperse in the rubber compound when it gathers into agglomerates, thus affecting the fusion with other ingredients such as reinforcing agent, vulcanizing agent, active agent and plasticizer. Therefore, the particle diameter is increased by granulation, and then processed It is not suitable to steam heat to remove moisture, and then separate the steam and materials through a screen; secondly, if the fine rubber powder of 38--100 mesh waste tires is separated through a screen, it is limited by the installation space of the drying cylinder, and the effectiveness of the screen is limited. The screening area is limited, and the rubber powder particles can easily block the screen mesh and reduce the screening efficiency; third, the method of environmental protection treatment of particulate matter with a dust cover at the discharge end cannot effectively prevent the rubber powder particles from escaping into the ambient air and causing pollution problem
