The present invention is one kind of acid soil amendment, which consists of coal burning fume desulfurizing solid waste in 83-97 wt% and humic acid in 3-17 wt%. The coal burning fume desulfurizing solid waste is formed through desulfurizing coal burning fume with lime suspension absorbing SO2. The acid soil amendment can complex or chelate Fe, Al and Mn elements of acid soil to regulate local concentration of active Fe, Al and Mn, raise the effectiveness and nourishing function of Ca, Mg, S, Si and B and raise activity of P, so as to raise the biomass and yield of crop and other plant and lower the content of nitrate in vegetable. The present invention utilizes coal burning fume desulfurizing solid waste effectively in agriculture.

The invention provides an environment-friendly tire molding device. According to the technical scheme, a conventional mode of a tire molding device is changed, and an enclosed cabin is used as a machining environment; and a heater and a mold are arranged in the cabin, and the molding of a tire is realized by hot pressing under the action of the high temperature mold. At the same time, a rotating grinding wheel is arranged beside the mold, and the grinding wheel is used for grinding the tire immediately after the molding of the tire, thereby shortening the operating process. In addition, an airsuction pipe for exhausting is disposed in the enclosed cabin to form a negative pressure environment in the cabin, and harmful gas generated by the hot pressing of rubber and dust particles generated by grinding are discharged through the air suction pipe; and since the outer end of the air suction pipe is provided with a gas filter, the environmental protection property of the tire molding process is greatly improved. In addition, in order to avoid dust adhering to the inner wall of the cabin during long-term operation, a cabin wall vibrator is arranged on the supporting columns to preventthe dust from sticking by vibration.
