Description

Technical Field

[0001] This utility model belongs to the field of blast furnace ironmaking technology, specifically relating to a cooling device for ironmaking waste slag. Background Technology

[0002] Blast furnace slag is a solid waste formed during the blast furnace ironmaking process from gangue in the ore, ash in the fuel, and non-volatile components in the solvent. To facilitate the handling of this blast furnace slag, it is generally cooled first before further processing. Existing waste slag cooling devices are equipped with screw conveyors to ensure the working effect of the device. The waste slag falling into the cooling chamber falls to the bottom of the screw conveyor, which then sends the waste slag back into the cooling chamber. During the conveying process, the waste slag comes into contact with the outside environment, causing a large amount of heat to be dissipated into the air, resulting in heat waste. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for ironmaking waste slag, comprising a cooling chamber, a feeding auger, a fan, and a liquid storage chamber, and also including a temporary storage chamber. The fan is installed on the cooling chamber, and an atomizing nozzle connected to a water tank is provided on the exhaust pipe of the fan. A pipe connected to the liquid storage chamber is provided on the side wall of the cooling chamber. A pipe connected to the top and bottom of the side wall of the cooling chamber is provided on the side wall of the feeding auger. The temporary storage chamber is provided on the cooling chamber and connected to the top pipe of the feeding auger. A storage frame is slidably installed at the bottom of the cooling chamber.

[0020] Please see Figure 1-6This utility model provides the following technical solution: a cooling device for ironmaking waste slag, including a cooling chamber 1, a feeding auger 2, a fan 4, and a liquid storage chamber 5, and also includes a temporary storage chamber 3. The cooling chamber 1 is equipped with a fan 4, and the exhaust pipe of the fan 4 is provided with an atomizing nozzle 41 connected to a water tank. The side wall of the cooling chamber 1 is provided with a pipe connected to the liquid storage chamber 5. The side wall of the feeding auger 2 is provided with pipes that are respectively connected to the top and bottom of the side wall of the cooling chamber 1. The cooling chamber 1 is provided with a temporary storage chamber 3 connected to the top pipe of the feeding auger 2. A storage frame 11 is slidably installed at the bottom of the cooling chamber 1. Several baffles 12 are arranged alternately inside the cooling chamber 1. Two electric rotating plates 13 are installed on the bottom baffle 12.

[0021] Cooling chamber 1 is used for moving waste materials to be cooled. Fan 4 is used to supply airflow into cooling chamber 1. Atomizing nozzle 41 is used to send water from the water tank in an atomized state into the air supply pipe of fan 4. After the water mist enters the exhaust pipe of fan 4, the airflow carries the water mist into cooling chamber 1. The airflow carrying the water mist comes into contact with the waste residue in cooling chamber 1. The water mist evaporates into water vapor under the heat of the waste residue, thus cooling the waste residue. Subsequently, the water vapor is carried by the airflow into the liquid storage chamber 5. The water vapor in the liquid storage chamber 5 comes into contact with the water stored in the liquid storage chamber 5. The heat of the water vapor is absorbed, and the temperature of the water stored in the liquid storage chamber 5 rises, thus recovering heat. The cooled airflow is then discharged. The air inlet pipe of the storage tank 5 is inserted into the water stored in the storage tank 5. The position of the air inlet pipe of the storage tank 5 can prevent the airflow containing water vapor from being discharged from the device without cooling. The storage tank 5 is equipped with a temperature detector, allowing the user to replace the water stored in the storage tank 5 in a timely manner, preventing the device's heat absorption capacity from being affected by excessively high water temperature inside the storage tank 5. The feeding auger 2 is used to transport the waste residue. After the waste residue is sent into the cooling chamber 1, it enters the feeding auger 2 through the bottom pipe connecting the cooling chamber 1 and the feeding auger 2. The feeding auger 2 will transport the waste residue to the top pipe connecting the cooling chamber 1 and the feeding auger 2, realizing the circulation of the waste residue and preventing the waste residue from being discharged. During the cooling process, the waste residue accumulates for a long time, affecting the efficiency of the device. The top and bottom pipes connecting the cooling chamber 1 and the feeding auger 2 are inclined towards the cooling chamber 1 and the feeding auger 2 respectively, ensuring smooth movement of the waste residue. The temporary storage chamber 3 is used to feed the waste residue to be cooled into the device. When the waste residue is fed into the cooling chamber 1, it moves on the baffles 12 installed inside the cooling chamber 1. The baffles 12 are inclined downwards to prevent the waste residue from accumulating on them. The baffles 12 are staggered on the cooling chamber 1, increasing the time the waste material moves within the cooling chamber 1 and ensuring the cooling effect of the device. During the movement of the waste material, it is constantly turned over to ensure that the waste material is cooled. Sufficient contact with the water mist-containing airflow ensures the device's cooling effect on the waste. The storage frame 11 is used to store the cooled waste residue. The electric rotating plate 13 is installed on the bottom baffle 12. When the device cools the waste residue, the electric rotating plate 13 seals the slot on the baffle 12, ensuring the waste residue can move smoothly. After the waste residue is cooled, the electric rotating plate 13 is rotated, the seal on the slot is released, and the cooled waste residue falls into the storage frame 11 after passing through the slot, thus achieving the collection of the cooled waste residue. The rotation method of the electric rotating plate 13 ensures that the distance between the electric rotating plate 13 and the storage frame 11 does not need to be too long, reducing the overall height of the device.The installation method of the storage frame 11 allows users to easily remove it from the cooling chamber 1, facilitating the collection of cooled waste residue. The top opening of the temporary storage chamber 3 is sealed with a plate, and the slot where the storage frame 11 is installed is sealed by the storage frame 11. The entire device is in a closed state, preventing heat from the waste residue from escaping to the outside during the cooling process and reducing heat waste.

[0022] Specifically, an electric telescopic plate 14 is provided at the position corresponding to the electric rotating plate 13 in the cooling chamber 1.

[0023] The electric telescopic plate 14 serves to flat support the electric rotating plate 13, ensuring that the electric rotating plate 13 will not be pushed up as the waste slag moves along the electric rotating plate 13, thus ensuring the stability of the electric rotating plate 13 during the use of the device. The electric telescopic plate 14 is set at both ends of the electric rotating plate 13, ensuring the supporting effect of the electric telescopic plate 14 on the electric rotating plate 13.

[0024] Specifically, the portion of the baffle 12 located outside the motor of the electric rotating plate 13 is provided with a heat insulation layer.

[0025] The heat insulation layer installed on the baffle 12 protects the motor of the electric rotating plate 13, preventing the heat from the waste residue from being conducted to the motor during the use of the device, thus avoiding affecting the service life of the motor.

[0026] Specifically, the temporary storage bin 3 is equipped with an electric rotating plate 31, and the side wall of the bottom discharge port of the temporary storage bin 3 is provided with a groove that cooperates with the electric rotating plate 31.

[0027] The electric rotating plate 31 installed on the temporary storage bin 3 can seal the connection between the temporary storage bin 3 and the top pipe of the feeding auger 2. During the heat dissipation process of the device, the staff can store the waste residue to be cooled in the temporary storage bin 3 in advance. After the waste residue inside the device has been cooled, the cooled waste residue is sent into the storage frame 11. Then the seal of the top opening of the top pipe of the cooling bin 1 by the electric rotating plate 31 is released, realizing the automatic feeding of waste residue. The part of the electric rotating plate 31 that seals the bottom opening of the temporary storage bin 3 is arc-shaped. The adjustment method of the electric rotating plate 31 reduces the space occupied by the electric rotating plate 31.

[0028] Specifically, the bottom surface of the groove for installing electric rotating plate 2 31 and electric rotating plate 1 13 is inclined.

[0029] The bottom shape of the groove where the electric rotating plate 2 31 and the electric rotating plate 1 13 are installed ensures that the waste residue will not fall off and accumulate inside the groove where the electric rotating plate 1 13 and the electric rotating plate 2 31 are installed during the movement, and ensures that the movement or rotation of the electric rotating plate 2 31 and the electric rotating plate 1 13 will not be obstructed.

[0030] Specifically, the liquid storage tank 5 has two liquid storage tanks inside, and the air inlet pipes of the liquid storage tanks are connected to the air inlet pipes of the liquid storage tank 5 through a three-way valve 51.

[0031] Users can change the liquid storage tank connected to the air inlet pipe of the liquid storage tank 5 through the three-way valve 51. When the temperature of the water stored in a liquid storage tank reaches the required level, the user can turn the three-way valve 51 to change the liquid storage tank connected to the air inlet pipe. At this time, the user can change the water in the liquid storage tank, drain the hot water and add cold water to the liquid storage tank. This ensures that the user's replacement of hot water will not affect the operation of the device. The exhaust port and the drain port of the liquid storage tank are located on different side walls to ensure that the cooled gas will not blow directly onto the staff.

[0032] Specifically, filters are installed at the openings of the exhaust duct of the blower 4 and the air inlet duct of the liquid storage tank 5.

[0033] The filters installed on the exhaust duct of the blower 4 and the air inlet duct of the liquid storage tank 5 serve a filtering function, preventing waste residue from entering the exhaust duct of the blower 4 and the air inlet duct of the liquid storage tank 5 during the movement of waste residue inside the cooling chamber 1.

[0034] The working principle and usage process of this utility model are as follows: Waste residue is added to the interior of the temporary storage chamber 3. The feeding auger 2, blower 4, and atomizing nozzle 41 are started. The electric rotating plate 31 is released from sealing the bottom opening of the temporary storage chamber 3, allowing the waste residue to enter the cooling chamber 1. The atomizing nozzle 41 sends water mist into the exhaust pipe of the blower 4. The airflow generated by the blower 4 sends the water mist into the interior of the cooling chamber 1. The water mist entering the cooling chamber 1 evaporates into water vapor under the heat of the waste residue. The water vapor enters the water in a storage tank in the liquid storage chamber 5 under the action of the airflow. The heat in the airflow is absorbed by the water. The cooled airflow is discharged, and the waste residue falls into the storage tank. After cooling chamber 1, the waste slag moves along baffle 12. As the waste slag moves, it enters feeding auger 2 through the bottom pipe connecting cooling chamber 1 and feeding auger 2. Feeding auger 2 conveys the waste slag upward. The waste slag conveyed to the top is sent back to cooling chamber 1 through the top channel connecting cooling chamber 1 and feeding auger 2. The circulating waste slag ensures the working effect of the device. After the waste slag is cooled, the electric telescopic plate 14 is released from fixing the electric rotating plate 13, and the electric rotating plate 13 is controlled to rotate. The electric rotating plate 13 releases the seal on the slot where the electric rotating plate 13 is installed, and the cooled waste slag falls into storage frame 11.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
