Description

Technical Field

[0001] This utility model relates to the technical field of heat dissipation towers, and in particular to heat dissipation towers for cooling water in carburizing furnaces. Background Technology

[0002] The carburizing furnace is a new type of energy-saving, cyclic-operation heat treatment electric furnace. Cooling water circulates within the furnace, helping to absorb the heat generated inside and preventing excessively high temperatures. This ensures the carburizing process occurs within a suitable temperature range, guaranteeing carburizing quality and extending the furnace's lifespan, while preventing damage to internal components due to high temperatures. Effective cooling reduces thermal stress on furnace components, preventing deformation and cracking. Cooling water radiator towers are commonly used in industrial and mining enterprises for rapid cooling of exchange water. Existing technology announcement CN215810295U proposes a novel intelligent circulating cooling water radiator tower, comprising a housing, a support frame for fixing the housing, and inlet and outlet water terminals installed on the housing for inputting and outputting cooling water. The inner wall of the housing is equipped with a temperature monitor, and the outer wall of the housing is equipped with a temperature display connected to the temperature monitor. A control panel is installed on the outer wall of the housing, and a water level monitoring device is installed on the inner wall of the housing. An alarm is installed on the control panel. However, the heat dissipation effect is slow and the water intake is small. Metallurgical enterprises use a large amount of cooling water, and a large number of these cooling towers need to be installed to meet the needs of the enterprises, which will undoubtedly increase the cost of installation, maintenance and operation. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a cooling tower for carburizing furnace cooling water that has a large unit water treatment capacity, increases the flow length and time of cooling water, and improves the heat dissipation effect and quality of cooling water.

[0004] The present invention relates to a cooling tower for a carburizing furnace, comprising a tower body, an inlet pipe, a water pump, an annular water distribution pipe, a connecting rod, an air extraction component, a flow slowing component, and an agitator. The inlet pipe is installed on the upper part of the tower body, and the water pump is installed on the inlet pipe. The annular water distribution pipe is installed on the upper side inside the tower body via the connecting rod. The output end of the water pump is connected to the input end of the annular water distribution pipe. Multiple water spray heads are provided at the bottom of the annular water distribution pipe. The air extraction component is installed on the top of the tower body. The flow slowing component is installed on the lower side inside the tower body. An agitator is installed at the bottom of the tower body. The water pump is started to deliver cold water through the inlet pipe into the annular water distribution pipe, where it is evenly sprayed into the tower body. The air extraction component extracts air from the tower body, causing air to flow within the tower and carry away the heat from the water. The flow slowing component increases the flow length and time of the cooling water, improving the heat dissipation effect and quality. At the same time, the agitator component stirs the water at the bottom after it has been cooled, ensuring that the water is evenly distributed and cooled rapidly, further improving the heat dissipation effect. It has a fast heat dissipation speed, a large unit water treatment capacity, and also has a good water filtration function.

[0005] Preferably, the air extraction component includes an exhaust pipe, an air extractor, multiple support rods, a conical top cover, and a conical guide block. The exhaust pipe is installed at the top of the tower body, and the air extractor is installed inside the exhaust pipe. The conical top cover is installed on the top of the exhaust pipe via multiple support rods, and a conical guide block is installed at the top of the conical top cover. Multiple air inlets are provided on the outer wall of the tower body. When the air extractor is started, air is extracted from the inside of the tower body. Air enters the tower body through the air inlets and flows inside, carrying away the heat from the water. After the air is discharged through the exhaust pipe, it is guided out by the conical guide block. The conical top cover can protect the top of the exhaust pipe to prevent the entry of debris.

[0006] Preferably, it also includes a filter screen, a baffle ring, and multiple guide plates. The filter screen is installed at the air inlet on the outer wall of the tower body, the baffle ring is installed above the air inlet on the outer wall of the tower body, and the multiple guide plates are axially arranged and installed on the inner wall of the tower body. The filter screen can filter the air entering at the air inlet, the baffle ring can protect and block the air above the air inlet, and the air entering the tower body is guided by the multiple guide plates.

[0007] Preferably, the flow-slowing component includes a baffle plate, a conical guide tube, multiple second guide plates, and cooling packing. The baffle plate is installed on the inner wall of the tower body below the air inlet. Multiple water drop troughs are provided on the baffle plate. A conical guide tube is installed in the middle of the baffle plate. Multiple second guide plates are axially installed on the outer wall of the conical guide tube. The cooling packing is installed on the inner wall of the tower body below the baffle plate. The water dripping down falls onto the cooling packing through the water drop troughs of the baffle plate. The cooling packing increases the heat dissipation, prolongs the residence time of the cooling water, increases the heat exchange area, increases the heat exchange capacity, and distributes the water evenly.

[0008] Preferably, it also includes multiple air supply pipes, which are evenly installed inside the cooling packing. Each air supply pipe has an air supply channel, multiple air supply holes at the top, and a cap at the top. When the air pump draws air, the gas at the bottom of the tower is input to the top of the cooling packing through the air supply pipes to enhance the heat dissipation effect.

[0009] Preferably, the agitating component includes a drive motor, a sleeve rod, a rotating shaft, multiple stirring blades, multiple vertical legs, and a water tank. The bottom of the tower body is installed inside the water tank via multiple vertical legs. A drive chamber is opened inside the conical guide tube, and the drive motor is installed in the drive chamber. The sleeve rod is installed at the bottom of the drive chamber and in the middle of the cooling packing. The rotating shaft is rotatably installed inside the sleeve rod, and the top of the rotating shaft is connected to the output end of the drive motor. Multiple stirring blades are installed at the lower part of the rotating shaft. After cooling, the water falls into the water tank. The drive motor is started to drive the rotating shaft to rotate, and the rotating shaft drives the stirring blades to rotate, agitating the water in the water tank, so that the water is evenly distributed and cooled quickly, further improving the heat dissipation effect and the heat dissipation speed is fast.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the water pump is started to input cold water into the annular water distribution pipe through the water inlet pipe and spray it evenly into the tower body. The air extraction component extracts air from the inside of the tower body, so that the air flows in the tower body and takes away the heat in the water. The flow slowing component can increase the flow length and time of the cooling water, thereby improving the heat dissipation effect and heat dissipation quality of the cooling water. At the same time, the stirring component stirs the water after it has been cooled at the bottom, so that the water is evenly distributed and cooled quickly, further improving the heat dissipation effect. The heat dissipation speed is fast, the unit water treatment capacity is large, and it also has a good water filtration function. Attached Figure Description

Multiple stirring blades 22 are installed at the bottom of the rotating shaft 21.

[0019] The water pump 3 is started to supply cold water through the inlet pipe 2 into the annular water distribution pipe 4, which is then sprayed evenly into the tower body 1. The air extractor 6 is started to extract air from the tower body 1. Air enters the tower body 1 through the air inlet and flows inside, carrying away the heat from the water. After being discharged through the air outlet pipe 5, the air is guided out by the conical guide block 9. The conical top cover 8 protects the top of the air outlet pipe 5 to prevent the entry of debris. The filter screen 11 filters the air entering through the air inlet, and the baffle ring 12 protects and blocks the area above the air inlet. The air entering the tower body 1 is then guided by multiple guide plates 15. The water is guided and dripped through the water dropper of the partition 13 onto the cooling packing 17.

Then, the air extractor 6 is started to extract air from the tower body 1. Air enters the tower body 1 through the air inlet and flows inside, carrying away heat from the water. After being discharged through the air outlet pipe 5, the air is guided out by the conical guide block 9. The filter screen 11 filters the air entering through the air inlet, and the baffle ring 12 provides protection above the air inlet. The air entering the tower body 1 is guided by multiple guide plates 15, and the water that is sprayed down falls onto the cooling packing 17 through the water dropper of the partition 13. The cooling packing 17 increases the heat dissipation and prolongs the residence time of the cooling water. When the air extractor 6 extracts air, the gas at the bottom of the tower body 1 is input into the cooling packing 17 through the air supply pipe 18. The cooled water falls into the water tank 24.
