Description

Technical Field

[0001] This utility model relates to the field of smelting furnace technology, and specifically to a safety protection device for smelting furnaces. Background Technology

[0002] A smelting furnace is a device that melts metal ingots and some scrap metals, adds necessary alloying components, and then melts them into the desired alloy through operations such as slag removal and refining. Its heating methods include fuel heating and electric heating. Safety protection devices for smelting furnaces are key equipment to ensure smooth production and protect personnel safety. They are usually made by using furnace doors to shield and seal the furnace chamber.

[0003] CN221055506U discloses a scrap metal melting furnace device, including a heating and melting furnace body. Two guide rails are fixedly installed on the front side of the furnace body, with grooves extending into the furnace body. A drive motor is positioned between the end rods of the two guide rails, and a lead screw is fixedly installed at the end of the motor's output shaft. A door panel assembly is mounted on the guide rails. The door panel assembly includes a base plate disposed within the furnace body and slidably connected to it. An insulated door panel is fixedly installed at the front end of the base plate, and a slider is fixedly installed on the bottom surface of the insulated door panel. The lead screw passes through the slider and is threadedly connected to it. Two guide plates are fixedly installed on the bottom surface of the base plate, and multiple furnace frames for supporting the melting furnace are provided on the base plate. This invention facilitates the opening and closing of the door panel and is convenient to use.

[0004] While the existing technology CN221055506U has many advantages in use, it still has the following problems: its handling of the gas inside the furnace is not perfect. During the smelting of metal parts inside the furnace, high temperature and toxic and harmful gases are generated. If the furnace door is opened directly, the high temperature and toxic and harmful gases inside the furnace will diffuse into the working environment, causing harm to the workers and affecting the safety of the smelting furnace. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a safety protection device for smelting furnaces.

[0006] The technical solution adopted by this utility model to solve its technical problem is a safety protection device for a smelting furnace, including a furnace chamber, a furnace door, and fixing components. A furnace door is provided on one side of the outer wall of the furnace chamber. Air inlets are provided on both sides of the lower end of the inner wall of the furnace chamber. An exhaust pipe is inserted and installed on one side of the outer wall of the furnace door. A shelf is welded to the lower end of one side of the outer wall of the furnace door. Fixing components are provided on both ends of the outer wall of the shelf. A support is welded to one side of the upper end of the inner wall of the furnace chamber. A heat insulation plate is welded to one end of the outer wall of the fixing component and the support. A sealing gasket is attached and fixed to one end of the outer wall of the heat insulation plate.

[0007] By adopting the above technical solutions, the air inlet and exhaust pipes ensure that the air inside the furnace can be connected with the outside. The heat insulation plates and sealing gaskets can shield the air inlet and exhaust pipes, preventing the internal temperature of the furnace from being transferred to the air inlet and exhaust pipes during use. The fixing and supporting components keep the two heat insulation plates in a stable position, ensuring that the heat and harmful gases inside the furnace can be effectively controlled. Furthermore, the heat insulation effect and sealing performance of the furnace are improved by the heat insulation plates and sealing gaskets, thereby protecting the surrounding environment and the safety of the operators.

[0008] Specifically, sealing rings are fixedly attached to both outer walls of the furnace door, and the sealing rings are in contact with the inner wall of the furnace.

[0009] By adopting the above technical solution, the sealing ring can further enhance the sealing performance of the furnace door, reduce the leakage of heat and harmful gases, and improve the safety protection effect. The two sealing rings can ensure the sealing performance. During the exhaust process inside the furnace, the furnace door is driven by the drive mechanism to move, causing the outer sealing ring to protrude out of the furnace chamber, while the inner sealing ring is located on the inner wall of the furnace chamber, maintaining the sealing performance inside the furnace chamber. At this time, the sealing gasket is no longer blocking the air inlet and exhaust pipe, allowing the furnace chamber to connect with the outside. Thus, through the exhaust pipe and its externally connected exhaust purification equipment, the air inside the furnace chamber can be discharged, ensuring the cleanliness of the air inside the furnace chamber after it is opened.

[0010] Specifically, slide rails are provided on both sides of the lower outer wall of the furnace chamber, and the lower outer wall of the furnace door is connected to the slide rails. A drive mechanism is provided on the lower outer wall of the furnace door. The drive mechanism consists of a screw, a connector, and a drive motor. The screw is rotatably installed at the lower end of the furnace chamber. The connector is connected to the lower outer wall of the furnace door, and the screw is threaded inside the connector. The drive motor is connected to the screw.

[0011] By adopting the above technical solutions, the design of the slide rail and drive mechanism allows the furnace door to be easily opened and closed, improving the convenience and efficiency of operation. At the same time, this design also ensures that the furnace door can fit tightly against the inner wall of the furnace when closed, further improving the sealing performance.

[0012] Specifically, the fastener has bolts inside, and the fastener is connected to the shelf via bolts.

[0013] By adopting the above technical solution, the bolts allow the heat insulation board to be firmly installed on the shelf, improving the stability and durability of the entire safety protection device.

[0014] Specifically, the two heat insulation boards are of the same size, and the size of the heat insulation board is larger than the size of the air inlet and the air outlet. The two heat insulation boards are respectively adapted to the layout positions of the air inlet and the air outlet, and the two sealing rings are respectively in contact with the inner wall of the furnace chamber and the inner side of the furnace door.

[0015] By adopting the above technical solution, the heat insulation plate ensures that the air inlet and exhaust pipes are not directly impacted by heat when not in use, thereby extending their service life. At the same time, the two sealing rings contact the inner wall of the furnace chamber and the inner side of the furnace door, respectively, which further improves the sealing performance.

[0016] Specifically, filter cartridges are installed at the lower ends of both sides of the outer wall of the furnace, and the positions of the filter cartridges correspond to the air inlet holes.

[0017] By adopting the above technical solution, the filter cartridge can effectively filter out impurities and harmful substances in the air entering the furnace, improve the air quality inside the furnace, and further protect the health of operators.

[0018] Specifically, the upper outer wall of the shelf is provided with equally spaced parallel furnace racks, and the furnace racks have storage slots inside.

[0019] By adopting the above technical solution, the tools and materials required inside the furnace can be conveniently stored and fixed, improving the convenience and efficiency of operation, and ensuring the stability of the furnace body after it is placed in the storage tank.

[0020] The beneficial effects of this utility model are:

[0021] (1) The safety protection device for smelting furnace described in this utility model ensures that the heat and harmful gases in the furnace chamber can be effectively controlled. It also improves the heat insulation effect and sealing performance of the furnace chamber through heat insulation plate and sealing gasket, thereby protecting the surrounding environment and the safety of operators.

[0022] (2) The safety protection device for a smelting furnace described in this utility model can exhaust the air inside the furnace chamber through the exhaust pipe and the exhaust purification equipment connected to it, so as to ensure the cleanliness of the air inside the furnace chamber after it is opened.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the safety protection device for a smelting furnace of this utility model includes a furnace chamber 1, a furnace door 2, and a fixing component 25. The furnace door 2 is provided on one outer wall of the furnace chamber 1. Air inlets 13 are provided on both sides of the lower end of the inner wall of the furnace chamber 1. An exhaust pipe 22 is inserted and installed on one outer wall of the furnace door 2. A storage plate 23 is welded to the lower end of one outer wall of the furnace door 2. Fixing components 25 are provided on the outer walls of both ends of the storage plate 23. A support component 15 is welded to one side of the upper end of the inner wall of the furnace chamber 1. A heat insulation plate 26 is welded to one outer wall of the fixing component 25 and the support component 15. A sealing gasket 27 is attached and fixed to one outer wall of the heat insulation plate 26.

[0031] During use, the air inlet 13 and exhaust pipe 22 ensure that the air inside the furnace chamber 1 can be connected with the outside. The heat insulation plate 26 and sealing gasket 27 can block the air inlet 13 and exhaust pipe 22, preventing the temperature inside the furnace chamber 1 from being transferred to the air inlet 13 and exhaust pipe 22 during use. The fixing part 25 and the support part 15 keep the two heat insulation plates 26 in a stable position, ensuring that the heat and harmful gases inside the furnace chamber 1 can be effectively controlled. The heat insulation effect and sealing performance of the furnace chamber 1 are also improved by the heat insulation plate 26 and sealing gasket 27, thereby protecting the surrounding environment and the safety of the operators.

[0032] For sealing, exemplarily, such as Figure 3 As shown, sealing rings 21 are fixedly attached to both outer walls of the furnace door 2, and the sealing rings 21 are in contact with the inner wall of the furnace chamber 1.

[0033] During use, the sealing ring 21 can further enhance the sealing performance of the furnace door 2, reduce the leakage of heat and harmful gases, and improve the safety protection effect. The two sealing rings 21 can ensure the sealing performance. During the exhaust process inside the furnace chamber 1, the furnace door 2 is driven to move by the drive mechanism 12, causing the outer sealing ring 21 to protrude out of the furnace chamber 1, while the inner sealing ring 21 is located on the inner wall of the furnace chamber 1, maintaining the sealing performance inside the furnace chamber 1. At this time, the sealing gasket 27 is no longer blocking the air inlet 13 and the exhaust pipe 22, allowing the furnace chamber 1 to connect with the outside. Thus, through the exhaust pipe 22 and the externally connected exhaust purification equipment, the air inside the furnace chamber 1 can be discharged, ensuring the cleanliness of the air inside the furnace chamber 1 after it is opened.

[0034] To drive movement, for example, such as Figure 1 As shown, slide rails 11 are provided on both sides of the lower outer wall of the furnace chamber 1, and the lower outer wall of the furnace door 2 is connected to the slide rails 11. A drive mechanism 12 is provided on the lower outer wall of the furnace door 2. The drive mechanism 12 consists of a screw, a connector and a drive motor. The screw is rotatably installed at the lower end of the furnace chamber 1, the connector is connected to the lower outer wall of the furnace door 2, and the screw is threaded inside the connector. The drive motor is connected to the screw.

[0035] During use, the design of the slide rail 11 and drive mechanism 12 allows the furnace door 2 to be easily opened and closed, improving the convenience and efficiency of operation. At the same time, this design also ensures that the furnace door 2 can fit tightly against the inner wall of the furnace chamber 1 when closed, further improving the sealing performance.

[0036] To fix the usage location, for example, such as Figure 4 As shown, the fastener 25 has bolts inside, and the fastener 25 is connected to the shelf 23 by bolts.

[0037] In use, the bolts allow the heat insulation plate 26 to be securely installed on the shelf 23, improving the stability and durability of the entire safety protection device.

[0038] For thermal insulation, for example, such as Figure 4 As shown, the two heat insulation plates 26 are the same size, and the size of the heat insulation plate 26 is larger than the size of the air inlet 13 and the exhaust pipe 22. The two heat insulation plates 26 are respectively matched with the layout positions of the air inlet 13 and the exhaust pipe 22, and the two sealing rings 21 are in contact with the inner wall of the furnace chamber 1 and the inner side of the furnace door 2, respectively.

[0039] When in use, the heat insulation plate 26 ensures that the air inlet 13 and the exhaust pipe 22 are not directly impacted by heat when not in use, thereby extending their service life. At the same time, the two sealing rings 21 contact the inner wall of the furnace chamber 1 and the inner side of the furnace door 2 respectively, which further improves the sealing performance.

[0040] For filtering purposes, for example, such as Figure 2 As shown, filter cylinders 14 are installed at the lower ends of both sides of the outer wall of the furnace chamber 1, and the positions of the filter cylinders 14 and the air inlet holes 13 are corresponding.

[0041] When in use, the filter cartridge 14 can effectively filter out impurities and harmful substances in the air entering the furnace, improve the air quality inside the furnace, and further protect the health of the operators.

[0042] To support the furnace body, for example, such as Figure 3 As shown, a furnace rack 24 is placed on the outer wall of the upper end of the shelf 23, and a storage slot is provided inside the furnace rack 24.

[0043] When in use, it can conveniently store and secure the tools and materials needed inside the furnace, improving the ease and efficiency of operation, and ensuring the stability of the furnace body when placed in the storage slot.

[0044] When using this utility model, the operator prevents the molten material from being inside the furnace body and places the furnace body inside the furnace frame 24. The drive motor is started, and the screw is driven to rotate. Through the connecting parts, the furnace door 2 is driven to slide along the slide rail 11 to the closed position. The sealing rings 21 on both sides of the furnace door 2 are in close contact with the inner wall of the furnace chamber 1 to form a seal. It is confirmed that the heat insulation plate 26 has completely blocked the air inlet 13 and the exhaust pipe 22 to prevent heat transfer.

[0045] After the melting is completed, the heating system is turned off, the drive motor is started, the screw is driven to rotate in the opposite direction, and the furnace door 2 is opened. At this time, the outer sealing ring 21 protrudes out of the furnace chamber 1, and the inner sealing ring 21 maintains the airtightness of the furnace chamber 1.

[0046] After the furnace door 2 is opened, the sealing gasket 27 is no longer blocking the air inlet 13 and the exhaust pipe 22, and the exhaust purification equipment is started, so that the air in the furnace chamber 1 is discharged to the outside through the exhaust pipe 22.

[0047] It should be noted that this utility model is a safety protection device for a smelting furnace. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
