Description

Technical Field

[0001] This utility model relates to the field of medium-frequency furnace cooling technology, specifically to an independent circulating water supply device for the furnace body and electrical cabinet of a medium-frequency furnace. Background Technology

[0002] As the core equipment for metal smelting and heat treatment, the induction coils and crucibles of the medium-frequency furnace and the capacitors, transformers and control modules of the electrical cabinet all generate a lot of heat during operation, which needs to be dissipated in time through a cooling system. In order to carry out liquid cooling of the furnace body and electrical cabinet, it is of great practical significance to develop an independent circulating water supply device for the furnace body and electrical cabinet of the medium-frequency furnace.

[0003] A reference announcement number CN205013390U describes an independent cooling water supply device, which includes a water tank with a cooling water return pipe and a cooling water outlet pipe. A water supply pump is installed on the cooling water outlet pipe. The device is characterized by having a cooler installed inside the water tank, the output end of which is connected to the input end of a gas compressor outside the water tank, the output end of which is connected to the input end of a condenser, and the output end of the condenser is connected to the input end of the cooler. While this device can be applied effectively, it typically uses a single pipeline, meaning the furnace body and electrical cabinet share the same pipeline and water pump. When the single pipeline water supply fails, both the furnace body and electrical cabinet simultaneously stop cooling, leading to overheating and potential damage to the equipment within a short period. Further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide an independent circulating water supply device for the furnace body and electrical cabinet of an intermediate frequency furnace, so as to solve the problem that although the device proposed in the background art can be applied well, it usually uses a single pipeline, that is, the furnace body and electrical cabinet share the same pipeline and water pump. When the single pipeline water supply fails, the furnace body and electrical cabinet will stop water supply for cooling at the same time, which will cause the equipment to overheat and be damaged in a short period of time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an independent circulating water supply device for the furnace body and electrical cabinet of a medium-frequency furnace, comprising a base, two support frames fixedly installed on one side of the top of the base, a water storage tank fixedly installed on the top of the support frames, an inlet flange port provided on one side of the top of the water storage tank, a drain pipe provided at the center of the bottom of the water storage tank, a connecting pipe installed at the end of the drain pipe away from the water storage tank, a first water supply pump mounted on the top of the base on the side of the connecting pipe away from the support frames via a bracket, and a second water supply pump mounted on the top of the base on the side of the first water supply pump via a bracket, the second... A fourth water supply pipe is installed at one end of the second water supply pump, and a third water supply pipe is installed at the other end of the second water supply pump. The end of the third water supply pipe away from the second water supply pump is connected to the outer wall of the connecting pipe. A second water supply pipe is installed at one end of the first water supply pump, and a first water supply pipe is installed at the other end of the first water supply pump. The end of the first water supply pipe away from the first water supply pump is connected to the outer wall of the connecting pipe. A control panel is fitted and installed on the top of the base on the side of the first water supply pump away from the connecting pipe. The output terminal of the microcontroller inside the control panel is electrically connected to the input terminals of the first water supply pump and the second water supply pump, respectively.

[0006] Preferably, a filter cover is installed at the bottom of the water storage tank at the location of the drainage pipe, and a pressure gauge is installed on the top of the water storage tank on the side of the liquid inlet flange. The pressure gauge is used to monitor and measure the pressure inside the water storage tank.

[0007] Preferably, a pressure relief pipe is provided on the top of the water storage tank on the side of the pressure gauge away from the inlet flange. A positioning seat is fixed at the top of the inside of the pressure relief pipe, and abutment blocks are provided on both sides of the bottom of the pressure relief pipe. The abutment blocks are provided to limit the downward movement of the piston block.

[0008] Preferably, a spring is installed at the bottom of the positioning seat, and a piston block is installed at the bottom of the spring. The outer wall of the piston block contacts the inner wall of the pressure relief pipe, and the bottom of the piston block contacts the top of the abutment block. An exhaust pipe is provided on one side of the outer wall of the lower end of the pressure relief pipe. The spring is used to apply downward elastic pressure to the piston block.

[0009] Preferably, a first pipe valve is installed on the outer wall of the first water supply pipe, and a second pipe valve is installed on the outer wall of the second water supply pipe. The first pipe valve and the second pipe valve are used to open and close the first water supply pipe and the second water supply pipe.

[0010] Preferably, a third pipe valve is installed on the outer wall of the third water supply pipe, and a fourth pipe valve is installed on the outer wall of the fourth water supply pipe. The third and fourth pipe valves are used to open and close the third and fourth water supply pipes.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the independent circulating water supply device for the furnace body and the electrical cabinet of the medium frequency furnace not only achieves the purpose of dual independent water supply to ensure the water supply effect when the water supply device is used, but also reduces the phenomenon of blockage when the water supply device is used, and achieves the purpose of easy self-adaptive pressure relief of the water storage tank.

[0012] (1) Connect the external water injection pipe through the liquid inlet flange to inject water into the water storage tank for storage, so that the water flows into the inside of the connecting pipe through the drain pipe. Then, connect the top of the second water supply pipe and the furnace body water inlet with a hose, and connect the top of the fourth water supply pipe and the electrical cabinet water inlet with another hose. Start the first water supply pump and the second water supply pump, and the water source can be transported into the furnace body through the first water supply pipe and the second water supply pipe, and the water source can be transported into the electrical cabinet through the third water supply pipe and the fourth water supply pipe, thereby achieving the purpose of dual independent water supply, thus ensuring the water supply effect when the water supply device is used.

[0013] (2) A filter cover is installed at the bottom of the water storage tank located outside the drainage pipe. When the water source inside the water storage tank flows into the drainage pipe, the filter cover will filter the particulate impurities in the water source to reduce the phenomenon of particulate impurities flowing into the pipe components of the water supply device and causing corrosion, thereby reducing the phenomenon of blockage when the water supply device is used.

[0014] (3) By applying downward elastic pressure to the piston block through the spring, if the pressure inside the water tank is high, the high pressure gas will flow into the interior of the pressure relief pipe and push the piston block to move upward. When the piston block moves upward to the interior of the pressure relief pipe above the exhaust pipe, the high pressure gas will be discharged through the exhaust pipe until the pressure inside the water tank is restored and the piston block moves downward to reset, thereby achieving the purpose of easy self-adaptive pressure relief of the water tank.

An exhaust pipe 25 is provided on one side of the outer wall of the lower end of the pressure relief pipe 6.

[0026] In use, the spring 22 is set so that a downward elastic pressure is applied to the piston block 23;

[0027] A connecting pipe 8 is installed at the end of the drainage pipe 7 away from the water storage tank 3. A first water supply pump 11 is installed at the top of the base 1 on the side of the connecting pipe 8 away from the support frame 2 via a bracket. A second water supply pump 17 is installed at the top of the base 1 on the side of the first water supply pump 11 via a bracket. A fourth water supply pipe 18 is installed at one end of the second water supply pump 17. A third water supply pipe 15 is installed at the other end of the second water supply pump 17. The end of the third water supply pipe 15 away from the second water supply pump 17 is connected to the outer wall of the connecting pipe 8. A third pipe valve 16 is installed on the outer wall of the third water supply pipe 15. A fourth pipe valve 19 is installed on the outer wall of the fourth water supply pipe 18.

[0032] In this embodiment, water is first injected into the storage tank 3 by connecting an external water inlet pipe 4 through the inlet flange port 4.

A flexible hose connects the top of the second water supply pipe 12 to the furnace inlet, and another flexible hose connects the top of the fourth water supply pipe 18 to the electrical cabinet inlet. Starting the first water supply pump 11 and the second water supply pump 17 delivers water to the furnace through the first and second water supply pipes 9 and 12, and to the electrical cabinet through the third and fourth water supply pipes 15 and 18, achieving dual independent water supply. Furthermore, the outlets of the electrical cabinet and furnace can be connected to an external cooling system via flexible hoses to recycle and cool the water used for cooling the electrical cabinet and furnace. Alternatively, a pumping mechanism can be used to connect the cooling system to the top of the inlet flange port 4. The water injection pipe delivers the recovered low-temperature water to the water storage tank 3 for easy water recycling. A filter cover 20 is installed at the bottom of the water storage tank 3, located outside the drain pipe 7. When water flows from the water storage tank 3 into the drain pipe 7, the filter cover 20 filters out particulate impurities, reducing the risk of blockages caused by these impurities entering the water supply system's pipe components. Finally, a spring 22 applies downward elastic pressure to the piston block 23. If the pressure inside the water storage tank 3 is high, high-pressure gas flows into the pressure relief pipe 6 and pushes the piston block 23 upward. When the piston block 23 moves to the pressure relief pipe 6 above the exhaust pipe 25, the high-pressure gas is discharged through the exhaust pipe 25. The piston block 23 returns to its original position after the pressure inside the water storage tank 3 is restored, facilitating adaptive pressure relief of the water storage tank 3 and completing the operation of the water supply system.
