In the sorting device adopted by the recycling method, no through hole is formed in the first plate body; a feeding port of the sorting cavity is located above the first screen, the upper end of the first screen is connected with the side wall of the sorting cavity, the lower end of the first screen is connected with the upper end of the first plate body, the lower end of the first plate body is located above the second screen, and the aperture of the first screen is smaller than that of the second screen. A gap is formed between the projection of the first screen and the projection of the second screen in the vertical direction, a feeding port of the second collecting bin is located under the first screen, a feeding port of the first collecting bin is located under the second screen, and the third collecting bin is located under the first plate body. The method can be used for recycling the waste tires.

This application belongs to the field of shower equipment technology and discloses a shower tray, including a tray base plate. The bottom of the tray base plate has a recessed groove, and the inner wall of the recessed groove is provided with evenly distributed imitation natural anti-slip texture. The bottom of the recessed groove has a drain cover relief groove, and a drain hole is provided through the drain cover relief groove. A rubber ring relief groove is provided around the drain hole near the drain cover relief groove. The bottom periphery of the tray base plate has hexagonal holes, and the bottom of the tray base plate has evenly distributed outer edging. The recessed groove is carefully carved into the bottom of the tray base plate. This design not only enhances the drainage efficiency of the plate, but also effectively prevents the risk of slipping in wet conditions through the evenly distributed imitation natural anti-slip texture on the inner wall of the recessed groove, ensuring the safety of users. The anti-slip measures imitate natural texture, which is both beautiful and practical. The outer edging and honeycomb structure are located at the bottom of the tray base plate, surrounding the outer wall of the hexagonal holes.

The invention relates to the technical field of asphalt modification, and discloses ardealite whisker composite modified asphalt and a preparation method thereof. The ardealite whiskers subjected to surface treatment are used as a base material and can enhance the high-temperature performance and structural stability of the base asphalt when being uniformly dispersed into the asphalt; the plasticizer can promote the uniform dispersion of the ardealite whiskers in the asphalt and reduce the adverse effect of the ardealite whiskers on the low-temperature performance of the asphalt due to the characteristics of powder materials; the dispersing agent can further enhance the dispersion uniformity of the ardealite whiskers under the synergistic effect of the plasticizer and promote the ardealite whiskers to form a cross-linked structure in the asphalt, so that the reinforcing effect on the asphalt is achieved; the stabilizer can enhance the storage stability of the modified asphalt, and the storage stability of the modified asphalt is enhanced by doping the stabilizer; the matrix asphalt is used as a main body material of the modified asphalt, and the service performance of the modified asphalt can be further enhanced through doping and synergistic effects of various modified materials, so that the modified asphalt can be better applied to asphalt pavements.
