Description

Technical Field

[0001] This utility model relates to a water-cooled grating cover, belonging to the technical field of steelmaking equipment in the metallurgical industry. Background Technology

[0002] Currently, large areas of the slab continuous casting workshop in steel enterprises are in high-temperature zones, especially the sides of the slab fan-shaped section and the upper part of the slab. During continuous production, employees need to inspect and maintain the equipment. However, traditional iron plate covers are prone to melting of safety shoes under high temperatures, causing employees to slip and fall. While sealed water tank covers can provide cooling, they can develop severe internal corrosion and cracks over time, which are difficult to detect. When employees walk on them, there is a risk of the cover breaking and causing them to fall. Therefore, there is an urgent need for a safe and reliable cover that can both reduce the surface temperature of the cover and visually eliminate potential safety hazards. Utility Model Content

[0003] The purpose of this utility model is to provide a water-cooled grating cover that can reduce the surface temperature of the cover, facilitate personnel movement, and eliminate safety hazards, thereby solving the problems existing in the background art.

[0004] The technical solution of this utility model is: A water-cooled grating cover includes an upper grating plate, an open water tank, an outlet, water flow guide baffles, and an inlet. The upper grating plate and the open water tank are mutually cooperating rectangles. The upper grating plate is embedded on the top of the open water tank. The inlet and outlet are located at the bottom of the open water tank and are respectively close to two opposite corners of the open water tank. Two parallel water flow guide baffles are fixed inside the open water tank. The two parallel water flow guide baffles cause the cooling water to flow in an S-shape from the inlet to the outlet.

[0005] The open water tank is equipped with a water storage baffle near the outlet.

[0006] The height of the water tank baffle near the outlet inside the open water tank is less than the height of the open water tank, and the angle between the water tank baffle and the open water tank forms a triangle.

[0007] The open water tank is equipped with a splash guard near the inlet.

[0008] The splash guard inside the open water tank, near the water inlet, is fixed between the open water tank body and the water flow guide baffle near the water inlet.

[0009] Both the inlet and outlet are equipped with valves.

[0010] The open water tank is equipped with several grid plate support ribs embedded in the upper grid plate.

[0011] The beneficial effects of this invention are as follows: This invention is located in the high-temperature zone of the fan-shaped section of the continuously cast slab. The lower part of the open water tank is connected to circulating water to maintain the water level in the tank at a certain height. The upper grating cover is placed on top of the water tank to allow personnel to walk on it. This structure not only reduces the surface temperature of the cover, making it suitable for personnel to walk on, but also allows for visibility by making the grating cover transparent both inside and out.

[0013] The present invention will be further described in detail below with reference to the embodiments.

[0014] See attached document Figure 1 A water-cooled grating cover includes an upper grating plate 1, an open water tank 2, an outlet 3, a water flow guide baffle 6, and an inlet 9. The upper grating plate 1 and the open water tank 2 are mutually cooperating rectangles. The upper grating plate 1 is embedded on the top of the open water tank 2. The inlet 9 and the outlet 3 are located at the bottom of the open water tank 2 and are respectively close to two opposite corners of the open water tank 2. Two parallel water flow guide baffles 6 are fixed inside the open water tank 2. The two parallel water flow guide baffles 6 make the flow direction of cooling water from the inlet 9 to the outlet 3 form an S-shape.

[0015] In this embodiment, as Figure 1 As shown, the water-cooled grating cover includes an upper grating plate 1, an open water tank 2, a water outlet 3, a water tank baffle 4, an open water tank shell 5, a water flow guide baffle 6, grating plate support ribs 7, a splash guard 8, and a water inlet 9, wherein: The upper grating plate 1 is 1750mm long, 960mm wide, and 40mm high; The open water tank 2 is made of 12mm thick steel plate, with a length of 1800mm, a width of 1000mm, and a height of 150mm; Install 1-inch water pipes and valves at outlet 3 and inlet 9 to regulate the flow and control the water level in the tank; The water tank baffle 4 is surrounded by a 60mm high-speed iron plate around the water outlet 3 and is fully welded to the open water tank shell 5. The water flow guide baffle 6 is made of two iron plates, each 1540mm long and 86mm high, welded together to guide the water flow from the inlet 9 to the outlet 3 in an S-shape. The grating support rib 7 is made of 6 iron plates, each 960mm long and 40mm wide, welded together. The splash guard 8 is made of iron plate with a length of 340mm and a width of 300mm, welded together.

[0016] After the open water tank 2 is welded, the upper grating plate 1 is embedded on top of the open water tank 2. The inlet and outlet water pipes are connected, and the flow rate is controlled by adjusting the valve opening to prevent the water in the tank from overflowing to the outside. The water tank baffle 4 can effectively control the water level in the tank to always be no less than 60mm, so that the water flows in the direction of flow to play a cooling role, and can also ensure the safety of personnel walking on the grating cover plate. At the same time, the cover plate is transparent inside and out, achieving visibility.
