The operating principle of the present disclosure is as follows. As shown in FIGS. 1 to 3, when the waste tire resourceful regeneration treatment method is applied, firstly, by sorting waste tires of different types, target waste tires with steel wires are obtained and placed together. Then, the target waste tires with steel wires are placed into a bead-cutting machine, the bead-cutting machine is started, and the beads with steel wires are removed from the target waste tires with steel wires by the tire bead cutting machine. Then the beads with steel wires are collected together. Then first remaining portions separated from the beads are placed into the strip-cutting machine, to cut the first remaining portions into strips of the same widths for facilitating a sequence step. Then beads is processed by a tire bead peeler, specifically, the beads is held by the tire bead peeler to remove the steel wires from the beads to obtain the steel wires and second remaining portions separated from the steel wires, and then the removed steel wires are collected centralizedly. Then, the waste wires without steel wires are placed into a tire block-cutting machine, a cutting feeding specification size of the tire block-cutting machine is adjusted to be in a range from 30 mm to 45 mm, the strips and the second remaining portions are placed into the tire block-cutting machine, and the tire block-cutting machine is started to obtain tire rubber blocks with a size in a range from 30 mm to 40 mm. Then, the cut tire rubber blocks are placed inside a cleaning tank to repeatedly clean the tire rubber blocks to flush dust and impurities attached to surfaces of the tire rubber blocks in a pressurized washing manner, and then the tire rubber blocks are vibrated by a vibrator inside the cleaning tank, the cleaning process is performed 3 to 6 times until the dust and impurities on the surface of the tire rubber block are substantially removed, and then the solid particle impurities and waste water generated after the cleaning are discharged through the cleaning tank. Then the generated waste water is processed by a water processing device to meet a qualified discharge standard. Then the tire rubber blocks after the cleaning are placed in an air-water-cooled system, a micro dust removal device and an atomization spraying system of a tire crusher, to soften the tire rubber blocks to change the characteristics of the tire rubber blocks, and then a crushing process is performed by adjusting a screen inside the tire crusher to be one thousand meshes. Then, the rubber powders obtained after the process of the tire crusher are collected and placed into a magnetic separator, the magnetic separator can remove 0.1 kilograms (kg) to 40 kg of a ferromagnetic material from the rubber powders through once magnetic separation, the ferromagnetic material in the rubber powders are repeatedly removed until the ferromagnetic material in the rubber powders is completely removed, thereby improve a quality of the rubber powders. Then, the rubber powders of which the ferromagnetic material is removed are placed into a fiber separation machine. A center of the fiber separation machine is provided with a transmission device, impellers is installed on a main shaft of the transmission device. The main shaft, a wind blade, and a wind blade plate are connected together with each other. With the rotation of the main shaft, the main shaft drives the impellers to rotate in a high-speed, to bring rubber powder particles and rubber powders with fine lint fibers into the fiber separation machine. The impellers on both sides of the fiber separation machine rotate rapidly to generate an airflow, under an action of the airflow, a wind pressure near the wind blade is lower than a wind pressure in the fiber separation machine, which causes of the fine lint fibers of the rubber powder particles or the rubber powders to rise and float, the fine lint fibers are discharged through a conduit under the action of the airflow, and the pure rubber powder particles and rubber powders cannot float due to a larger gravity thereof, thereby ensuring that the desired fibers are separated. Then, the rubber powders obtained after the fiber separation are sieved. Then, the rubber powders obtained after the sieving is placed into a vulcanizer, and a desulfurization steam temperature in the vulcanizer is controlled to be 540° C. for ensuring an effect of rubber powder desulfurization. Then, the rubber powders obtained after the desulphurizing are placed into a cooling chamber for cooling, and then recycled resources including the steel wires, the rubber powders and the fibers are obtained finally from the waste tires. Ultra-fine rubber powders of one thousand meshes are finally obtained, thereby ensuring a quality of the ultra-fine rubber powders, while optimizing the process and improving a utilization rate of the recycled resources, which are the characteristics of this waste tire resourceful regeneration treatment method.
