The invention relates to a carrying device used for carrying bars away from a quenching bath. The carrying device comprises a main body frame. A spindle is mounted on the upper portion of the main body frame and connected with a motor. A first pulley and a second pulley are mounted on the spindle in sequence. A mooring rope is mounted on the second pulley. A main lifting frame is tied to the lower end of the mooring rope. A ball screw is mounted on the lower portion of the main lifting frame and connected with the motor. A smooth rod is fixedly mounted on the upper portion of the main lifting frame. Two leg frames are slidably mounted on the smooth rod. A clamping opening is formed in the lower end of each leg frame. The carrying device is ingenious in structure and can automatically clamp and release the bars while driving the bars to do lifting movement through belt transmission and incomplete gear steering functions under the conditions of motor drive and belt tensioning due to spring extrusion, and the effect of carrying the bars away from the quenching bath through convenient and rapid operation and control mode is achieved.

The invention provides a simulated remediation system and a method for underground water containing 1, 2-dichloroethane. According to the system, a rectangular tank-type shell with an opening in the top is sequentially divided into a pollution source section, a pollutant migration and transformation section and a pollutant remediation section from left to right; the sample space layers of the pollution source section and the pollutant migration and transformation section are soil sample filling layers; the sample space layer of the pollutant remediation section is sequentially provided with apyrite filling layer, an oxide filling layer and a tourmaline filling layer from left to right. Pyrite is adopted to catalyze persulfate; the natural material tourmaline is introduced into the Fenton-like reaction, so that the pH value and redox potential of the aquifer are optimized, the remediation environment of persulfate in underground water on 1, 2-dichloroethane is integrally improved, andthe effectiveness and practicability of an in-situ chemical oxidation system in remediation of degradation-resistant organic polluted underground water are obviously improved.

The smart heating desk is provided with the heating device which can automatically release the heat and provides a proper study temperature for students concentrating on writing and reading; in addition, the heating device is intelligently controlled. The smart heating desk is simple in structure and is easy to mount and produce.

The invention relates to a method for preparing coated sustained-release calcium fertilizer from a waste seafood shell, which belongs to the field of preparation of sustained-release calcium fertilizer. The method provided by the invention is directed at the problems of soil hardening caused by excessive application of calcium fertilizer and difficulty in absorption of common bio-calcium and comprises the following steps: desalinating the waste seafood shell; then carrying out alkaline hydrolysis and pumping filtration so as to prepare seafood chitosan; preparing a sustained-release coating material from seafood chitosan; and coating treated bio-calcium. The sustained-release calcium fertilizer prepared in the invention can be automatically realized in soil and has an action period of 15 to 30 d; and through preparation of the fertilizer from the waste seafood shell, resources are saved, and greenness and environmental protection are realized.

A piston cylinder control system for a wheeled hydraulic excavator, comprising: an auxiliary hydraulic pump; an auxiliary opening check valve locking the piston cylinder; a piston cylinder control valve adapted to respond to a valve control signal from an original The position is switched to the operating position to allow the hydraulic oil from the auxiliary hydraulic pump to open the check valve so that the hydraulic oil can be discharged from the piston cylinder; the brake pressure sensor is used to detect the hydraulic oil pressure supplied to the brake device; the joystick position detection controller for detecting the position of the joystick to generate one of a forward position signal, a rearward position signal and a neutral signal; and a controller, if a forward position signal or a rearward position signal is received and if the brake pressure If it is not greater than the set pressure, the controller applies the valve control signal to the piston cylinder control valve, if it receives a neutral signal and if the brake pressure exceeds the set pressure, the controller cuts off the application to the piston cylinder control valve valve control signal.
