Description

Technical Field

[0001] This utility model relates to the field of protective slag drying technology, specifically to a protective slag drying device. Background Technology

[0002] Mold flux is an important auxiliary material in continuous casting production, which has greatly expanded and improved the types of continuously cast steel, the variety of continuously cast cross sections, the quality of continuously cast billets, and the productivity of continuous casting. Therefore, it has long been an indispensable metallurgical auxiliary material. Mold flux is usually an irregular granular powder, which is prone to absorbing moisture and becoming damp during storage. If the moisture content of the mold flux is too high, it will cause violent splashing of molten steel during casting, threatening the safety of operators and increasing the oxygen content of the molten steel, which will affect the quality of the steel. Therefore, mold flux needs to be dried before use. The traditional method of dehumidifying mold flux is to bake it by supporting steel plates or small end caps on a platform. This method requires repeated manual stirring, resulting in excessive labor intensity for workers and poor drying efficiency. Utility Model Content

[0003] In view of this, the present invention provides a protective slag drying device, which can improve the drying and dehumidification effect of protective slag, reduce the labor intensity of workers, and achieve high drying efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides a protective slag drying device, including a barrel body, a feed pipe on one side of the upper part of the barrel body, a discharge pipe at the center of the lower part of the barrel body, and a high-efficiency drying mechanism inside the barrel body. The high-efficiency drying mechanism includes a drying drum and a dehumidification component located at the center of the barrel body. The drying drum is used to hold the protective slag, and the bottom of the drying drum is connected to the discharge pipe. The dehumidification component is used to dehumidify and dry the protective slag inside the drying drum. The operator pours the protective slag into the drying drum through the feed pipe, and then the dehumidification component dries and dehumidifies the protective slag. This can improve the drying and dehumidification effect of the protective slag, reduce the labor intensity of workers, and achieve high drying efficiency.

[0005] The dehumidification assembly includes a heating element and a stirring element. The heating element includes a heating chamber with an inner wall of the barrel, containing an electric heating wire. A controller is located on the outer wall of the barrel and is electrically connected to the electric heating wire. Fans are installed on both sides of the inner wall of the barrel, with the fan input located inside the heating chamber and the fan output located inside the barrel. Ventilation holes are located on both outer walls of the barrel and are connected to the interior of the heating chamber. The operator activates the electric heating wire via the controller to heat the air inside the heating chamber, and then activates the fans to blow the hot air from the heating chamber into the barrel. Simultaneously, ventilation is achieved through the ventilation holes, allowing the hot air to heat the interior of the barrel and dehumidify and dry the protective residue inside the drying barrel. The stirring mechanism further agitates the protective residue, thus improving the drying effect.

[0006] The stirring component includes a support pipe rotatably mounted on the center of the upper wall of the tank. Two connecting pipes are mounted on the surface of the support pipe, and several stirring pipes are evenly arranged on the surface of the connecting pipes. Stirring blades are mounted on the surface of the stirring pipes. A motor is mounted on the other side of the upper part of the tank. The output end of the motor passes through the upper wall of the tank and is equipped with a drive gear. A driven gear is mounted on the upper surface of the support pipe, meshing with the drive gear. When the operator starts the motor, the motor output end drives the drive gear to rotate. The rotation of the drive gear drives the driven gear, which in turn drives the support pipe to rotate. The rotation of the support pipe, in turn, drives the connecting pipes and stirring pipes to rotate, thus stirring the protective slag. Combined with hot air drying, this improves the drying effect of the protective slag.

[0007] A heat circulation mechanism is installed at the top inside the barrel. The heat circulation mechanism is used to heat the stirring tube. By heating the stirring tube through the heat circulation mechanism, the heated stirring tube can simultaneously stir and heat the protective slag. By heating and drying the inside of the protective slag, the drying effect of the protective slag is further improved.

[0008] The heat circulation mechanism includes a second air supply pipe located at the lower part of the inner wall of the barrel. One end of the second air supply pipe is located inside the lower part of the barrel, and the other end of the second air supply pipe penetrates through the inner wall of the barrel. An air pump is installed at one end of the second air supply pipe, and a first air supply pipe is installed at the output end of the air pump. A heat exchange frame is located at the upper center of the barrel. A bearing is fixed to the inner wall of the heat exchange frame, and the outer ring of the bearing is fixed to the inner wall of the heat exchange frame. A support column is fixed to the inner ring of the bearing. A through hole adapted to the support column is opened at the bottom of the heat exchange frame. The upper end of the support column penetrates through the through hole at the bottom of the heat exchange frame, and the upper outer wall of the support column is fixed to the inner ring of the bearing. The first air supply... The end of the tube penetrates the upper wall of the heat exchange frame. The support tube is hollow and its upper part is connected to the inside of the heat exchange frame. The support tube is connected to the inside of the connecting tube and the stirring tube. The upper outer wall of the support tube has an exhaust hole. When the hot air fills the tank, the air pump is started. The air pump delivers the air to the first air supply pipe through the second air supply pipe, then into the heat exchange frame through the first air supply pipe, then into the support tube through the heat exchange frame, then into the connecting pipe through the support tube, and finally into the stirring tube through the connecting pipe, thereby heating the stirring tube. At the same time, the hot air re-enters the tank, realizing heat circulation.

[0009] The bottom of the support pipe is equipped with a guide plate with several guide holes evenly opened on the surface of the guide plate. After the protective slag is dried, the discharge pipe is opened to discharge the protective slag from the drying barrel. At the same time, when the support pipe rotates, it drives the bottom guide plate to rotate together, so that the guide plate can stir and clear the protective slag blocking the discharge pipe and improve the uniformity of discharge.

[0010] The surface of the stirring tube is evenly equipped with several stirring blades, the cross-section of which is spiral. The stirring blades can improve the stirring effect of the protective slag.

[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0012] 1. When using this utility model, the worker pours the protective residue into the drying barrel through the feed pipe, and then dries and dehumidifies the protective residue through the dehumidification component. This can improve the drying and dehumidification effect of the protective residue, reduce the labor intensity of workers, and achieve high drying efficiency.

[0013] 2. When using this utility model, the operator starts the electric heating wire through the controller, so that the electric heating wire heats the air inside the heating chamber. Then, the fan is started, and the fan blows the hot air in the heating chamber into the barrel. At the same time, the air is exchanged through the vent, so that the hot air heats the inside of the barrel, thereby dehumidifying and drying the protective residue in the drying barrel. At the same time, the stirring mechanism stirs the protective residue in the drying barrel, which can improve the drying effect of the protective residue.

[0014] 3. When using this utility model, the operator starts the motor, and the output end of the motor drives the drive gear to rotate. When the drive gear rotates, it drives the driven gear. When the driven gear rotates, it drives the support tube to rotate. When the support tube rotates, it drives the connecting tube and the stirring tube to rotate, so that the stirring tube stirs the protective slag. Combined with the drying of hot air, the drying effect of the protective slag is improved.

[0015] 4. When this utility model is in use, after the hot air is filled into the barrel, the air pump is started.
