Description

Technical Field

[0001] This utility model relates to the field of electroslag furnace cooling technology, specifically to a multi-stage water-cooled circulating cooling device for electroslag furnaces. Background Technology

[0002] An electroslag furnace is a special smelting equipment that uses remelting current to generate heat to melt consumable electrodes inserted into a slag pool. After the molten metal droplets are cleaned by the slag liquid, they crystallize into electroslag ingots in a water-cooled crystallizer.

[0003] Electroslag furnaces are widely used in industrial production, but they generate a lot of heat during operation, requiring an effective cooling system to ensure stable operation. Traditional cooling methods often suffer from low heat dissipation efficiency, high energy consumption, and complex equipment. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage water-cooled circulating cooling device for electroslag furnaces to solve the problems mentioned in the background art.

[0007] The circulation mechanism includes a collection frame, an installation plate fixedly connected to the left side of the collection frame, a third water pump fixedly connected to the top of the installation plate, a third suction pipe fixedly connected to the right side of the third water pump, and a circulation pipe fixedly connected to the top of the third water pump.

[0009] Preferably, the end of the first suction tube away from the first water pump passes through the top of the water storage frame and extends into the water storage frame.

[0010] Furthermore, the end of the first suction pipe away from the first water pump not only penetrates the top of the water storage frame but also extends into the interior of the water storage frame. The first water pump draws water from inside the water storage frame through the first suction pipe, and then, after being pressurized by the first water pump, it is transported through the conveying pipe to the cooling pipe to cool the electroslag furnace body.

[0011] Preferably, a water injection pipe is fixedly connected to the top of the water storage frame, and a pipe cap is snapped onto the top of the water injection pipe. The cooling pipe is wrapped around the outside of the electroslag furnace body, and multiple supports are provided, with the inner side of each of the multiple supports fixedly connected to the outer side of the cooling pipe.

[0012] Furthermore, a water injection pipe is fixedly connected to the top of the water storage frame. This water injection pipe is used to add water to the water storage frame, and the top of the water injection pipe has a snap-on cap to seal the water injection pipe and prevent water evaporation or contamination. The cooling pipe is tightly wrapped around the outside of the electroslag furnace body to ensure maximum cooling effect. At the same time, the bracket is not only connected to the electroslag furnace body, but also fixed to the outside of the cooling pipe through its inner side, further stabilizing the position of the cooling pipe.

[0013] Preferably, the end of the cooling pipe away from the delivery pipe is fixedly connected to the front end of the heat pipe, and multiple heat dissipation fins are provided, which are evenly distributed inside the cooling frame.

[0014] Furthermore, the end of the cooling pipe furthest from the delivery pipe is fixedly connected to the front end of the heat pipe, allowing the cooling water in the cooling pipe to transfer heat to the heat pipe. The heat dissipation fins are evenly distributed inside the cooling frame, increasing the heat dissipation area and improving heat dissipation efficiency.

[0015] Preferably, the cooling frame has multiple hollowed-out heat dissipation holes on both the front and rear sides and the rear. The end of the second suction tube away from the second water pump is fixedly connected to the rear of the heat pipe, and the end of the connecting pipe away from the second water pump is connected to the top of the collection frame.

[0016] Furthermore, multiple perforated heat dissipation holes are provided on the front, back, and rear sides of the cooling frame, which help dissipate the heat inside the cooling frame to the external environment. The end of the second suction tube away from the second water pump is fixedly connected to the rear of the heat pipe, so that water in the heat pipe can be drawn out by the second water pump through the second suction tube and then transported to the collection frame through the connecting pipe.

In this way, the third water pump can draw water from the bottom of the collection box through the third suction pipe. The end of the circulation pipe away from the third water pump not only passes through the top of the water storage box, but also extends into the inside of the water storage box. In this way, the water pressurized by the third water pump can flow back into the water storage box through the circulation pipe, forming a circulating cooling system.

[0019] Preferably, a slot is provided on the right side of the collection frame, and the filter screen is snapped into the slot on the right side of the collection frame.

[0020] Furthermore, a slot is provided on the right side of the collection box, and the filter screen is connected to this slot by snapping. The snapping connection method of the filter screen is also easy to disassemble and clean, ensuring the long-term stable operation of the cooling system.

[0021] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0022] Firstly, this utility model involves adding an appropriate amount of cooling water through the water injection pipe at the top of the water storage frame and closing the pipe cover. The cooling pipe is wrapped around the outside of the electroslag furnace body. Multiple supports are used to fix and connect the cooling pipe to the electroslag furnace body. When the electroslag furnace body starts working, the first water pump draws water from the water storage frame through the first suction pipe and sends the cooling water into the cooling pipe through the delivery pipe. The cooling pipe is wrapped around the outside of the electroslag furnace body and removes heat from the electroslag furnace through heat conduction. The cooling pipe can be made of stainless steel, which can balance performance and economy. The heated cooling water flows into the heat pipe through the cooling pipe and is further dissipated in the heat pipe. The heat is transferred to multiple heat dissipation fins through the heat pipe. At the same time, the fan starts, and the heat is transferred through the protective shield. Air is drawn in through the mesh and blown over the heat dissipation fins, enhancing the heat dissipation effect. The cooled water is then pumped out from the rear end of the heat pipe by the second water pump and the second suction pipe, and discharged into the collection frame through the connecting pipe. The third water pump draws water from the bottom of the collection frame through the third suction pipe and sends the cooling water back to the storage frame through the circulation pipe, completing the circulation of cooling water. The combination of heat dissipation fins and fans further enhances the heat dissipation effect. The fan accelerates the airflow by blowing over the heat dissipation fins, carrying away the heat on the heat dissipation fins, thereby achieving more efficient heat exchange. The cooling pipes are tightly wrapped around the outside of the electroslag furnace body to ensure that heat is quickly conducted to the cooling medium. Through the multi-stage cooling structure of cooling pipes and heat pipes, the heat generated by the electroslag furnace body can be absorbed and dispersed more effectively.

[0023] Secondly, when cooling water flows out of the heat pipe in the cooling frame through the connecting pipe and enters the collection frame, the filter screen intercepts and removes impurities, particulate matter, and other possible contaminants from the water. The clean cooling water filtered by the filter screen can then be pumped out by the third water pump and returned to the storage frame through the circulation pipe for reuse. When the filter screen needs cleaning, the support plate is grasped to pull the filter screen out of the slot on the right side of the collection frame. The filter screen is then cleaned and reinserted into the slot on the right side of the collection frame. The filter screen is easy to disassemble and clean, effectively removing impurities and particulate matter from the water, preventing damage to the device, and reducing the difficulty and frequency of device maintenance.

When the electroslag furnace body 106... At startup, the first water pump 102 draws water from the water storage frame 101 through the first suction pipe 103 and delivers the cooling water to the cooling pipe 105 through the delivery pipe 104. The cooling pipe 105 is wrapped around the outside of the electroslag furnace body 106 and carries away the heat of the electroslag furnace through heat conduction.
