Description

Technical Field

[0001] This utility model relates to a water source heating device for refractory material construction in furnaces and kilns during winter, and belongs to the field of metallurgical equipment technology. Background Technology

[0002] Refractory materials, often simply called refractories, mostly use water as an admixture to achieve fluidity, plasticity, and hardening. In winter, refractory construction in northern regions is affected by low temperatures. For water-based unshaped refractories, the construction process suffers from slow setting and hardening, and prolonged curing time. When the temperature drops below 0℃, "frozen material" is prone to occur, affecting construction progress. Insufficient residual temperature during the curing stage can also lead to "frost damage" defects inside the refractory components, namely increased porosity and reduced strength.

[0003] Refractory material construction in steel plants is frequent, and hot water is inconvenient to obtain during winter construction. The traditional method is to use electric heating to obtain hot water, but this method is wasteful due to high hot water consumption, unpredictable construction schedules, and the need for a constant supply of hot water. Furthermore, it poses a risk of electric shock during the work process. The saturated steam generated by the cooling system during steelmaking is an inexhaustible heat resource. Utilizing this waste heat to heat the water source for refractory material construction would be significant for energy conservation, emission reduction, lower production costs, and elimination of safety risks. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a water heating device for refractory material construction in winter furnaces, thereby reducing energy waste, lowering production costs, and eliminating the risk of electric shock.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water source heating device for refractory construction in winter furnaces includes a water tank, an inlet valve, a drain valve, and a heat exchange tube. An inlet pipe is provided on the upper part of one side of the water tank, passing through the side wall of the water tank. One end of the inlet pipe located outside the water tank is connected to a water source through the inlet valve. The drain valve is installed on the lower part of one side of the water tank. The heat exchange tube is located inside the water tank. The steam inlet end of the heat exchange tube is connected to a steam pipe located on one side of the water tank, and the other end is connected to the atmosphere through a steam outlet located at the top of the water tank.

[0007] The aforementioned water source heating device for refractory construction in winter furnaces also includes a water temperature control device. The water temperature control device includes an electrically controlled steam valve, a temperature control box, and a temperature probe. The temperature control box is installed on the side wall of the water tank. The electrically controlled steam valve is installed on the steam pipe connected to the steam inlet of the heat exchange tube and is connected to the temperature control box via a cable. The temperature probe is immersed in the water inside the water tank, and the signal output end of the temperature probe is connected to the temperature control box. A temperature adjustment knob is provided on the temperature control box.

[0008] The water source heating device described above for refractory construction in winter furnaces and kilns has a water tank equipped with a float valve and a float inside. The float valve is installed on the water inlet pipe of the water tank, and the float is connected to the float valve via a connecting rod.

[0009] The water source heating device described above for refractory construction in winter furnaces has a water level gauge and a thermometer installed on the side wall of the water tank.

[0010] The water source heating device described above for refractory construction in winter furnaces has an openable and closable observation window on the top of the water tank.

[0011] The aforementioned water heating device for refractory construction in winter furnaces has a spiral-shaped heat exchange tube.

[0012] This invention uses saturated steam generated during the enterprise's production process to heat the water source for refractory material construction in furnaces and kilns.

Detailed Implementation

[0016] This invention addresses the shortcomings of existing technologies by providing a water source heating device for refractory construction in winter furnaces. This device can utilize the saturated steam resources generated by the steel plant's cooling system to heat the water source, and can regulate and control the water temperature and store hot water resources to ensure the smooth progress of refractory construction in winter.

[0017] See Figure 1 This utility model mainly includes a water tank 1, an inlet valve 2, an electrically controlled steam valve 3, a float valve 4, a float 5, a temperature control box 6, a temperature adjustment knob 7, a temperature probe 8, a cable 9, a steam outlet 10, a heat exchange tube 11, a drain valve 12, a water level gauge 13, a thermometer 14, and an observation window 15.

[0018] The inlet valve 2 is installed on the inlet pipe on the upper side of the water tank 1. The inlet pipe passes through the side wall of the water tank 1 and is connected to the float valve 4 inside the water tank.

[0019] The float 5 rises and falls with the water level. When the float 5 reaches its limit, it closes the float water valve 4 via a connecting rod, cutting off the water supply. When the float 5 is in the non-limited state, the float water valve 4 is open, restoring water supply. By controlling the action of the water level on the float 5, the opening and closing of the float water valve 4 is controlled, maintaining the water level and achieving automatic water replenishment.

[0020] The electrically controlled steam valve 3 is installed on the steam pipe on the upper side of the water tank 1. The steam pipe passes through the side wall of the water tank 1 and is connected to the heat exchange tube 11 inside the water tank 1. After the steam enters the heat exchange tube 11 through the electrically controlled steam valve 3 and the water has exchanged heat, it is discharged through the steam outlet 10 at the top of the water tank 1.

[0021] The heat exchange tube 11 is located inside the water tank 1. To increase the heat exchange efficiency, the heat exchange tube 11 is arranged in a spiral coil.

[0022] The temperature control box 6 is installed on the side wall of the water tank 1. The electric steam valve 3 is connected to the temperature control box 6 via cable 9. The temperature control box 6 is provided with a temperature signal by a temperature probe 8 immersed in water inside the water tank 1. The temperature control box 6 is equipped with a temperature adjustment knob 7 for setting the heating temperature of the water source.

[0023] When the temperature control box 6 detects that the water temperature meets the temperature setting value of the temperature control knob 7 through the temperature probe 8, it controls the closing of the electric steam valve 3 to stop steam heating; conversely, when the water temperature is lower than the temperature setting value of the temperature control knob 7, it controls the opening of the electric steam valve 3 to start steam heating.

[0024] A drain valve 12 is installed on the lower side of water tank 1 for drawing hot water during construction.

[0025] A water level gauge 13 is installed on the side wall of the water tank 1 above the drain valve 12. The water level gauge 13 operates on the principle of "U-tube".

[0026] A thermometer 14 is installed on the outside of the water tank 1 to facilitate verification of whether the water temperature meets the set requirements before hot water is drawn.

[0027] The top of the water tank 1 is equipped with an openable and closable observation window 15 for maintenance of the water tank 1.

[0028] The working process of this utility model is as follows: Water enters the water tank 1 through the inlet valve 2 and the float valve 4. After the water level causes the float 5 to rise to the limit, the float valve 4 cuts off the water supply. Steam enters the heat exchange tube 11 through the electrically controlled steam valve 3 to heat the water source and is then discharged through the steam outlet 10. The temperature control knob 7 is adjusted to set the preset water temperature. After the temperature probe 8 collects the water temperature signal, it is transmitted to the temperature control box 6. The temperature control box 6 determines that the water temperature meets the preset water temperature and then cuts off the electrically controlled steam valve 3 to stop heating. Before the hot water is connected for construction, the water temperature and water level are manually verified to meet the usage conditions by using the thermometer 14 and the water level gauge 13 outside the water tank 1. After the water level drops, the float 5 controls the float valve 4 to open and replenish the water source. After the temperature control box 6 determines that the water temperature has dropped, it opens the electrically controlled steam valve 3 to start heating. If the water tank malfunctions, it is inspected through the observation window 15.

[0029] This invention utilizes saturated steam generated by the cooling system of a steel plant to heat water sources, and can regulate and control the water temperature and store hot water resources to ensure the smooth progress of refractory construction in winter. The application scenarios of this invention include, but are not limited to, steel enterprises; other industries involving winter refractory construction and with abundant steam resources, such as glass factories and power plants, are also within the scope of this invention.

[0030] This invention has a simple structure and low cost. Compared with traditional electric heating methods, it can reduce energy waste, lower production costs, and eliminate the risk of electric shock.
