Description

Technical Field

[0001] This utility model relates to the field of steelmaking converter technology, and in particular to a device for self-regulating the temperature and level of slag rake cooling water. Background Technology

[0002] In the converter smelting process, removing slag from molten iron before smelting can reduce steel material consumption and is an important measure to reduce costs. However, the slag rake of the slag remover is in direct contact with the molten iron, and the slag removed is at a high temperature. If it is not cooled in time, the molten iron slag will continue to burn the slag rake at a high temperature, which will aggravate the burning of the slag rake and increase the cost of spare parts. Therefore, it is necessary to use a cooling water pool to cool down the slag rake.

[0003] When cooling water is used to cool the slag rake, some of the water evaporates upon contact with the hot rake. If water is not added promptly, the cooling effect on the rake will decrease. Furthermore, temperature monitoring is crucial to prevent the water from overheating and hindering efficient cooling. Currently, adding cold water and draining hot water are done manually, requiring workers to measure the water depth and temperature and then open valves accordingly – a highly inconvenient process. Therefore, this invention proposes a self-regulating device for the cooling water temperature and level of the slag rake to address the shortcomings of existing technologies. Utility Model Content

A control box is installed on the outer wall of the cooling water pool. The inlet valve, drain valve, level sensor, and thermometer are all electrically connected to the control box.

[0007] A separation component is located at the bottom of the cooling water tank, and a hot and cold water rapid mixing mechanism is located inside the cooling water tank below the separation component.

[0008] A further improvement is that: water distribution pipes are provided on the front and rear side walls of the upper part of the cooling water pool, and the cold water inlet pipe is connected to the two water distribution pipes through a branch pipe. The water distribution pipes are provided with water distribution holes, and there are multiple water distribution holes.

[0009] A further improvement is that the separation component includes a first filter plate and a second filter plate, with the second filter plate located below the first filter plate, and the aperture of the first filter plate being larger than that of the second filter plate.

[0010] A further improvement is that the hot and cold water rapid mixing mechanism includes a main shaft and blades. The main shaft is provided in at least two sets, and multiple sets of the main shaft are rotatably connected to the interior of the cooling water tank. Blades are provided on the main shaft, and multiple sets of blades are provided in pairs.

[0012] A further improvement is that the cooling water pool is equipped with a perforated mesh cover, the lower end of which is connected to the top of the first filter plate.

[0013] The beneficial effects of this utility model are as follows: By setting an inlet valve on the cold water inlet pipe and a drain valve on the hot water outlet pipe, setting a liquid level sensor to measure the liquid level, and setting a thermometer to measure the temperature of the pool water, this utility model can realize the automatic control of the inlet valve and the drain valve by the control box, realize the automatic addition of cold water and the discharge of hot water, so as to maintain the stability of the pool water level and the pool water temperature.

[0014] This invention, by setting up a separation component, can use the first filter plate and the second filter plate to intercept solids falling during the cooling process of the slag rake, thus preventing solids from entering the hot water discharge pipe and causing pipe blockage.

Detailed Implementation

[0022] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0023] according to Figure 1-5 As shown, this embodiment proposes a self-regulating device for cooling water temperature and level of a slag rake, including a cold water inlet pipe 2 leading to a cooling water pool 1 and a hot water outlet pipe 3 located below the side wall of the cooling water pool 1 and communicating with the interior of the cooling water pool 1. The cold water inlet pipe 2 is equipped with an inlet valve 4, and the hot water outlet pipe 3 is equipped with a drain valve 5. A level sensor 6 is installed on one side wall inside the cooling water pool 1, and a thermometer 7 is installed on the other side wall inside the cooling water pool 1. A control box 8 is installed on the outer wall of the cooling water pool 1. The inlet valve 4, drain valve 5, level sensor 6, and thermometer 7 are all electrically connected to the control box 8. A separation component is installed at the lower interior of the cooling water pool 1, and a rapid hot and cold water mixing mechanism is installed inside the cooling water pool 1 below the separation component.

[0024] When the cooling water temperature and level self-regulating device of this utility model is in operation, the liquid level sensor 6 and the thermometer 7 monitor the liquid level and water temperature of the water in the cooling water pool 1 respectively. When the liquid level sensor 6 detects that the water level is too high, the control box 8 controls the drain valve 5 to open to discharge the pool water until the liquid level in the cooling water pool 1 reaches the set value. When the liquid level sensor 6 detects that the water level is too low, the control box 8 controls the inlet valve 4 to open to discharge external cold water into the cooling water pool 1 until the liquid level reaches the set value. When the thermometer 7 detects that the water temperature is too high, the control box 8 controls the drain valve 5 to open to discharge the pool water, and opens the inlet valve 4 according to the drainage volume and water temperature measurement results to replenish the cooling water pool 1 with cold water until the pool water level and temperature both reach the set values.

[0025] The cooling water tank 1 has water distribution pipes 9 on its upper front and rear side walls. The cold water inlet pipe 2 is connected to the two water distribution pipes 9 through a branch pipe 10. Each water distribution pipe 9 has multiple water distribution holes 11. By setting up the water distribution pipes 9 and the water distribution holes 11 on them, the cooling water in the cold water inlet pipe 2 can be uniformly introduced into the cooling water tank 1 to mix with the hot water in the tank, thereby replenishing the liquid level and regulating the tank water temperature.

[0026] The separation assembly includes a first filter plate 12 and a second filter plate 13. The second filter plate 13 is located below the first filter plate 12, and the aperture of the first filter plate 12 is larger than that of the second filter plate 13. The first filter plate 12 and the second filter plate 13 can achieve graded interception of solids to prevent solids from clogging the hot water discharge pipe.

[0027] The rapid hot and cold water mixing mechanism includes a main shaft 14 and blades 15. At least two sets of main shafts 14 are provided, and multiple sets of main shafts 14 are rotatably connected to the interior of the cooling water tank 1. Blades 15 are mounted on the main shafts 14, and multiple sets of blades 15 are arranged in pairs. A drive motor 16 is mounted on the outer wall of the cooling water tank 1, and the drive motor 16 is positioned to match the position of the main shafts 14. The main shafts 14 are driven by the drive motor 16. When the rapid hot and cold water mixing mechanism is running, the drive motor 16 is activated to control the rotation of the main shafts 14, causing the blades 15 to agitate the water in the cooling water tank 1, thereby rapidly adjusting the water temperature in the cooling water tank 1.

[0028] The cooling water tank 1 is equipped with a perforated mesh cover 17, the lower end of which is connected to the top of the first filter plate 12. By setting the perforated mesh cover 17, the water distribution pipe 9, the liquid level sensor 6, and the thermometer 7 can be blocked, preventing the slag rake from touching the water distribution pipe 9, the liquid level sensor 6, and the thermometer 7 when it enters the cooling water tank 1.

[0029] This invention features an inlet valve 4 on the cold water inlet pipe 2 and a drain valve 5 on the hot water outlet pipe 3. A level sensor 6 measures the water level, and a thermometer 7 measures the water temperature. The control box 8 automatically controls the inlet valve 4 and drain valve 5 to automatically add cold water and discharge hot water, maintaining a stable water level and temperature in the cooling water tank 1. A separation assembly, using a first filter plate 12 and a second filter plate 13, intercepts solids falling during the cooling process of the slag rake, preventing them from entering the hot water outlet pipe 3 and causing blockage. A rapid hot and cold water mixing mechanism, using a main shaft 14 and blades 15, mixes the cold and hot water in the cooling water tank 1, resulting in a more uniform water temperature, improving the accuracy of the thermometer 7, and better cooling the slag rake.
