Description
Technical Field
[0001] The utility model relates to the technical field of electric furnaces, in particular to an electric furnace with a protection device. Background Technique
[0002] High-temperature industrial electric furnaces are important equipment in industrial production, mainly used for heating and melting various materials, such as metals, ceramics, etc. According to different heating methods and application scenarios, high-temperature industrial electric furnaces have various different types and classifications. Existing industrial electric furnaces usually add a pressure relief and exhaust pipeline inside to discharge the high-temperature steam inside.
[0003] Existing industrial electric furnaces usually discharge the internal high-temperature gas before opening the discharge port. However, since the metal being processed inside still has a relatively high temperature, it will heat the surrounding environment again, resulting in a large amount of high-temperature gas still overflowing after the discharge port is opened. Improper operation will cause burns.
[0004] Therefore, aiming at the above-mentioned existing industrial electric furnaces, which lack a protection structure at the discharge port and have a problem of a large amount of high-temperature gas overflowing, an electric furnace with a protection device can be designed. By starting the air pump, the suction head can perform the pumping operation, so that after the inlet and outlet are opened, the overflowing high-temperature steam and dust can be inhaled to avoid the scattering of high-temperature steam. Content of the Utility Model
[0005] In order to overcome the problem that existing industrial electric furnaces usually discharge the internal high-temperature gas before opening the discharge port, and since the metal being processed inside still has a relatively high temperature, it will heat the surrounding environment again, resulting in a large amount of high-temperature gas still overflowing after the discharge port is opened.
[0006] The technical solution of the utility model is: an electric furnace with a protection device, including an electric furnace body; it also includes an electric guide rail, an electric slider, a connecting rod, a suction head, a conduit and an air pump. There is an inlet and outlet in the middle of the top surface of the electric furnace body. There are four columns arranged in a rectangular array on the outside of the electric furnace body. The opposite surfaces of the two right columns are connected with an equipment shell. There is an electric guide rail on the left side of the equipment shell. The outer surface of the electric guide rail is slidably connected with an electric slider. The bottom surface of the electric slider is equipped with a connecting rod. The bottom of the connecting rod is equipped with a suction head. One end of a conduit is arranged at the rear side position of the upper surface of the suction head. The other end of the conduit is connected with an air pump.
[0007] Preferably, by setting an electric slider, in cooperation with an electric guide rail, the connecting seat can drive the suction head installed at its bottom to move left and right. At the same time, start the air pump. Through the connection of the conduit, the suction head can perform the air extraction operation. Thus, after opening the inlet and outlet, the overflowing high-temperature steam and dust can be inhaled, preventing the high-temperature steam from spreading and scalding the surrounding staff. This solves the problem that when the existing electric furnace is in use, only the high-temperature gas is discharged through the internal exhaust pipe, and no protective device is added at the port position of the electric furnace. Due to the high internal temperature, a large amount of high-temperature gas will still overflow after opening the cover, easily causing the risk of scalding personnel.
[0008] Preferably, a driving motor is installed on the front side of the inner surface of the equipment shell. The output end of the driving motor is installed with a screw rod. A moving seat is threadedly connected to the outer surface of the screw rod. The left side surface of the moving seat is connected to the right side surface of the electric guide rail. By the operation of the driving motor, the screw rod can be driven to rotate, thereby driving the moving seat on its surface to move back and forth, so as to drive the electric guide rail to move back and forth, and thus the operation range of the suction head can be expanded and the protection effect can be improved.
[0009] Preferably, a limiting rod is connected to the opposite surfaces of the two left struts. A limiting groove is opened on the right side surface of the limiting rod. A limiting block is installed on the left side surface of the electric guide rail. The limiting block is slidably connected to the limiting groove. By opening the limiting groove, when the electric guide rail moves back and forth, the limiting block will slide synchronously inside the limiting groove, thereby improving the stability and smoothness of the equipment operation.
[0010] Preferably, a treatment box is arranged at the right side position of the electric furnace body. The bottom surface of the air pump is connected to the top surface of the treatment box. A filter screen is arranged at the upper end inside the treatment box. A water tank is arranged at the bottom of the inner surface of the treatment box. By setting the treatment box, the high-temperature steam inhaled from the suction head will be discharged into the interior of the treatment box through the conduit. The filter screen filters impurities such as dust doped in the high-temperature steam, and then it is introduced into the water tank for cooling treatment.
[0011] Preferably, mounting blocks are installed on both the left and right side surfaces of the filter screen. The filter screen is slidably connected to the inner surface of the treatment box through the mounting blocks. By setting the mounting blocks, it is convenient for the staff to quickly disassemble and assemble the filter screen, so as to clean and replace the filter screen daily.
[0012] Preferably, a water pump is installed on the inner bottom surface of the water tank. A water delivery pipe is connected to the front surface of the water pump. The water delivery pipe sequentially penetrates through the lower ends of the outer surfaces of the four support columns. Spray bars are installed at the side positions of the four support columns. The spray bars are connected to the water delivery pipe through the inner hoses of the support columns. By setting the water pump, the operation of the water pump will pump the cooling water inside the water tank into the water delivery pipe. The water delivery pipe then transmits the cooling water into the hoses inside each support column, and then the spray bars spray it in a mist form, thereby forming a protective barrier outside the electric furnace body, reducing the temperature of the environment around the electric furnace body, and at the same time avoiding the overflow of high-temperature steam, improving the protection effect.
[0013] Preferably, a base is provided on the bottom surface of the electric furnace body. Legs distributed in a circle are provided on the outer surface of the base. By setting the base and the legs, the contact area between the electric furnace body and the ground can be increased, thereby improving the installation stability.
[0014] The beneficial effects of the present utility model are as follows:
[0015] 1. By setting the electric slider, in cooperation with the electric guide rail, the connecting seat can drive the suction head installed at its bottom to move left and right. At the same time, start the air pump. Through the connection of the conduit, the suction head can perform the air extraction operation. Thus, after opening the feeding and discharging port, the overflowing high-temperature steam and dust can be inhaled, avoiding the scattering of high-temperature steam and scalding the surrounding staff. This solves the problem that when the existing electric furnace is in use, only the high-temperature gas is discharged through the internal exhaust pipe, and no protective device is added at the port of the electric furnace. Due to the high internal temperature, a large amount of high-temperature gas will still overflow after opening the cover, which is likely to cause the risk of scalding personnel.
[0016] 2. By setting the treatment tank, the high-temperature steam inhaled from the suction head will be discharged into the interior of the treatment tank through the conduit. The impurities such as dust mixed in the high-temperature steam are filtered by the filter screen, and then introduced into the water tank for cooling treatment. And by setting the water pump, the operation of the water pump will pump the cooling water inside the water tank into the water delivery pipe. The water delivery pipe then transmits the cooling water into the hoses inside each support column, and then the spray bars spray it in a mist form, thereby forming a protective barrier outside the electric furnace body, reducing the temperature of the environment around the electric furnace body, and at the same time avoiding the overflow of high-temperature steam, improving the protection effect.

At the same time, the air pump 10 is started. Through the connection of the duct 9, the suction head 8 can perform air extraction operation. Thus, after the feeding and discharging port 2 is opened, the overflowing high-temperature steam and dust can be sucked in, avoiding the scattering of the high-temperature steam and scalding the surrounding staff.
[0024] Please refer to Figures 1-4, in this embodiment, a driving motor 13 is installed on the front side of the inner surface of the equipment housing 4. The output end of the driving motor 13 is installed with a screw rod 14. A moving seat 15 is threadedly connected to the outer surface of the screw rod 14. The left side surface of the moving seat 15 is connected to the right side surface of the electric guide rail 5. By operating the driving motor 13, the screw rod 14 can be driven to rotate, thereby driving the moving seat 15 on its surface to move back and forth, so as to drive the electric guide rail 5 to move back and forth, thereby expanding the operation range of the suction head 8 and improving the protection effect. The opposite surfaces of the two left-side struts 3 are connected with a limiting rod 16. A limiting groove 17 is opened on the right side surface of the limiting rod 16. A limiting block 18 is installed on the left side surface of the electric guide rail 5. The limiting block 18 is slidably connected with the limiting groove 17. By opening the limiting groove 17, when the electric guide rail 5 moves back and forth, the limiting block 18 will slide synchronously inside the limiting groove 17, thereby improving the stability and smoothness of the equipment operation. A processing box 19 is arranged at the right position of the electric furnace body 1. The bottom surface of the air pump 10 is connected to the top surface of the processing box 19. A filter screen 20 is arranged at the upper end inside the processing box 19. A water tank 22 is arranged at the bottom of the inner surface of the processing box 19. By arranging the processing box 19, the high-temperature steam inhaled from the suction head 8 will be discharged into the interior of the processing box 19 through the conduit 9. The filter screen 20 filters impurities such as dust doped in the high-temperature steam, and then is introduced into the water tank 22 for cooling treatment.
[0025] Please refer to Figures 2-4 , in this embodiment, mounting blocks 21 are installed on both the left and right side surfaces of the filter screen 20. The filter screen 20 is slidably connected to the inner surface of the processing box 19 through the mounting blocks 21. By arranging the mounting blocks 21, it is convenient for the staff to quickly disassemble and assemble the filter screen 20, so as to clean and replace the filter screen 20 daily. A water pump 23 is installed on the inner bottom surface of the water tank 22. The front side surface of the water pump 23 is connected with a water delivery pipe 24. The water delivery pipe 24 sequentially penetrates through the lower ends of the outer surfaces of the four struts 3. Spraying strips 25 are installed at the side positions of the four struts 3. The spraying strips 25 are connected to the water delivery pipe 24 through the inner hoses of the struts 3. By arranging the water pump 23, the operation of the water pump 23 will pump the cooling water inside the water tank 22 into the water delivery pipe 24. The water delivery pipe 24 then transmits the cooling water into the hoses inside each strut 3, and then is sprayed out in a mist form by the spraying strips 25, thereby forming a protective barrier outside the electric furnace body 1, reducing the temperature of the environment around the electric furnace body 1, and at the same time avoiding the overflow of high-temperature steam, improving the protection effect. A base 11 is arranged on the bottom surface of the electric furnace body 1. Legs 12 distributed in a circular pattern are arranged on the outer surface of the base 11. By arranging the base 11 and the legs 12, the contact area between the electric furnace body 1 and the ground can be increased, thereby improving the installation stability.
[0026] When working, the operation of the drive motor 13 can drive the screw 14 to rotate, thereby driving the moving seat 15 on its surface to move back and forth, so as to drive the electric guide rail 5 to move back and forth, thereby expanding the working range of the suction head 8 and improving the protection effect. And by opening the limit groove 17, when the electric guide rail 5 moves back and forth, the limit block 18 will slide synchronously inside the limit groove 17, thereby improving the stability and smoothness of the equipment operation. And by setting the treatment box 19, the high-temperature steam inhaled from the suction head 8 will be discharged into the treatment box 19 through the conduit 9. The dust and other impurities doped in the high-temperature steam will be filtered by the filter screen 20, and then introduced into the water tank 22 for cooling treatment. And by setting the mounting block 21, it is convenient for the staff to quickly disassemble and install the filter screen 20, so as to clean and replace the filter screen 20 daily. And by setting the water pump 23, the operation of the water pump 23 will pump the cooling water in the water tank 22 into the water delivery pipe 24. The water delivery pipe 24 will then transmit the cooling water into the hoses inside each support column 3, and then be sprayed out in a mist form by the spray bar 25, so as to form a protective barrier outside the electric furnace body 1, reduce the temperature of the surrounding environment of the electric furnace body 1, and at the same time avoid the overflow of high-temperature steam, improve the protection effect, and by setting the base 11 and the support legs 12, the contact area between the electric furnace body 1 and the ground can be increased, thereby improving the installation stability.
[0027] Through the above steps, by setting the electric slider 6, in cooperation with the electric guide rail 5, the connecting seat can drive the suction head 8 installed at its bottom to move left and right. At the same time, start the air pump 10. Through the connection of the conduit 9, the suction head 8 is made to perform the air extraction operation, so that after the feeding and discharging port 2 is opened, the overflowing high-temperature steam and dust can be inhaled, avoiding the scattering of the high-temperature steam and scalding the surrounding staff. In this way, it solves the problem that when the existing electric furnace is in use, only the high-temperature gas is discharged through the internal exhaust pipe, and no protection device is added at the port position of the electric furnace. Due to the high internal temperature, a large amount of high-temperature gas will still overflow after the cover is opened, which is likely to cause the risk of scalding people.
