The road isolation device for urban road traffic engineering comprises a combined isolation box and an isolation plate, a green plant planting box used for beautifying urban roads is arranged in the isolation box, and a recycling hopper, a recycling pipe, a water tank and the isolation box are assembled, so that the road isolation device can recycle a certain amount of water in rainy weather; according to the green plant planting box, water resources can be saved when green plants planted in the isolation box are watered, a screen is arranged in the isolation box, water flowing out of water leakage holes in the bottom of the green plant planting box can be filtered through the screen, then separation between the water and impurities such as soil is achieved, and the filtered water flows into the water tank, so that water resources are saved. And after quantitative water is recycled in the water tank, the overall gravity of the water tank is increased, and then the stability of the isolation box placed on the urban traffic road is improved.

The application belongs to the technical field of building construction, and particularly relates to a precast beam hoisting and transporting device, which comprises a hoisting beam, a sling, a first half sliding sleeve, a second half sliding sleeve and a reset spring. Before the precast beam is hoisted and transported, the reset spring at both ends of the inner cavity is pushed to make the first half sliding sleeve and the second half sliding sleeve be at the central position of the inner cavity, so that the length of both ends of the sling is always consistent. During the hoisting and transporting of the precast beam, when the precast beam is slightly inclined, the sling drives the first half sliding sleeve and the second half sliding sleeve to slide along the inner cavity to the side, the reset spring at the side is compressed, and the reset spring at the other side is stretched. The elastic force generated by the reset springs at both sides can make the first half sliding sleeve and the second half sliding sleeve reset to the central position of the inner cavity, drive the height of both ends of the sling to return to the horizontal state, thereby adjusting and restoring the precast beam to the horizontal state, and then the stability and safety of the hoisting and transporting of the precast beam are improved.

This application relates to a method and system for removing iron from electrode paste raw materials after crushing. The method utilizes a material conveyor belt to transport residual anodes at fixed intervals, passing them below the iron remover body to reduce the "magnetic curtain effect." The height difference between the leading edge of the iron remover body and the material pile is adjusted based on the thickness of the material pile before it enters the magnetic field range of the iron remover body. This fully utilizes the attraction of the magnetic field on material piles of any thickness, effectively preventing the desired material from being mistakenly screened out when the material pile thickness is higher than the bottom plane of the iron remover body. The gradually decreasing thickness of the material pile is obtained sequentially along the material pile's movement path. The height difference between the trailing edge of the iron remover body and the material pile is adjusted based on multiple thickness values. This ensures that the attraction of the iron remover body to the fine iron-containing impurities buried in the lower layer of the material pile by materials of normal particle size increases progressively. This allows the horizontal component of the inclined magnetic field to overcome part of the resistance from the downward pressure of the material, improving the screening rate of small and medium-sized iron-containing impurity blocks pressed by the material.
