Description

Technical Field

[0001] This utility model relates to the field of industrial furnace technology, specifically to an industrial furnace with a dust treatment structure. Background Technology

[0002] Industrial kilns are key thermal equipment used in industrial production for processes such as material heating, melting, sintering, and calcination. Their development history is closely related to the progress of human civilization. From open-air burning and pit burning in primitive society, to ancient steamed bun kilns, dragon kilns, and horseshoe-shaped kilns, and then to modern electric kilns, gas kilns, and large continuous kilns, kiln technology has made continuous breakthroughs in the fields of materials, energy, and control.

[0003] Existing designs use multi-stage filtration systems in filtration devices to filter dust. However, since industrial furnaces and kilns produce different items, their power varies. When operating at high power, the fixed pipe diameter cannot remove dust in time, which may cause blockages in the pipes and filtration mechanisms of the filtration system.

[0004] To overcome the above-mentioned defects, the prior art (Chinese patent announcement number: CN119353933A, publication date: 2025-01-24) discloses a dust adsorption device for industrial furnaces, including an industrial furnace, a support frame, a gas collection and filtration mechanism, and an emission mechanism. The support frame is installed at the upper end of the industrial furnace, the gas collection and filtration mechanism is installed in the middle of the support frame, and the emission mechanism is installed in the middle of the gas collection and filtration mechanism. The gas collection and filtration mechanism includes a gas collection unit, a rotating unit, and a diversion unit. The gas collection unit is installed at the upper end of the industrial furnace, the rotating unit is installed in the middle of the gas collection unit, and the diversion unit is installed in the middle of the gas collection unit. This dust adsorption device for industrial furnaces, by installing the diversion unit in the gas collection and filtration mechanism, sets the first emission diversion pipe, the second emission diversion pipe, and the third emission diversion pipe to three heights, thereby meeting most usage conditions and preventing the emission rate from being too low due to excessively narrow pipes, thus increasing the smoothness of emission filtration.

[0005] While the above design can solve the aforementioned problems, the existing design is very complicated to operate when dust needs to be discharged and is not efficient enough in cleaning dust. It cannot quickly complete the dust cleaning work during high-intensity work. At the same time, when it is necessary to remove the finished product, the existing design often requires the entire equipment to be opened, which means that the preheating operation needs to be repeated for the next work. Such a design makes the equipment less energy-efficient and the continuous heating process reduces the efficiency of the equipment. Utility Model Content

[0006] The purpose of this utility model is to provide an industrial furnace with a dust treatment structure to solve the problems mentioned in the background art. The existing design is very complicated to operate and has insufficient dust cleaning efficiency when dust needs to be discharged. It cannot quickly complete the dust cleaning work during high-intensity work. At the same time, when it is necessary to take out the finished product, the existing design often requires the entire equipment to be opened, so that the preheating operation needs to be repeated for the next work. Such a design makes the equipment less energy-efficient and the continuous heating process reduces the efficiency of the equipment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an industrial furnace with a dust treatment structure, including a bottom support base, a furnace processing box installed above the bottom support base, an elastic dust removal mechanism for swinging the processing placement box inside the furnace processing box, the elastic dust removal mechanism including a rotary drive motor, the rotary drive motor being fixedly installed on the upper surface of the bottom support base, a rotary retraction rod being installed on the outer surface of the output end of the rotary drive motor, and a transmission connection mechanism for raising and lowering the sliding insulation plate being installed on the outer surface of the rotary retraction rod.

[0008] Furthermore, the transmission connection mechanism includes a retractable connecting rope, with one end of the retractable connecting rope fixedly installed on the outer surface of the rotating retractable rod, and the other end of the retractable connecting rope fixedly installed on the top of the sliding insulation plate, and a heat-insulating hollow frame is installed on the outer surface of the output end of the furnace processing box.

[0009] Furthermore, the sliding insulation plate is slidably installed inside the heat-insulating hollow frame, and the bottom support base and the heat-insulating hollow frame are internally connected. Two sets of the shrink connecting ropes are symmetrically installed about the center point of the rotating shrink rod, and a material conveying port is installed on the top of the furnace processing box.

[0010] Furthermore, a rotating retraction rod is installed on the outer surface of the output end of the rotary drive motor, and swing limit frames are installed on both sides of the inner surface of the bottom support base. The lower sides of the processing placement box slide along the inside of the swing limit frames, and a lateral abutment spring is installed on the inner surface of the furnace processing box.

[0011] Furthermore, the ends of the lateral contact springs abut against the corresponding left and right sides of the processing and placement box, and a limit biting rod is installed on the inner surface of the bottom support base. An inclined driving plate is installed on the outer surface of the limit biting rod, and the top of the inclined driving plate is designed with an incline.

[0012] Furthermore, the rotation trajectory of the rotating retraction rod abuts against the top inclined surface of the inclined driving plate, and the inclined driving plate slides along the outside of the limiting engagement rod. The lower end of the inclined driving plate engages with the inside of the processing placement box, and two sets of swing limiting frames and lateral engagement springs are symmetrically installed about the center point of the processing placement box.

[0013] Furthermore, the lower opening of the material conveying port corresponds to the installation position of the processing and placement box, and the inner surface of the heat-insulating hollow frame contacts the outer surface of the sliding insulation plate to form a sliding structure. Moreover, the rotating retraction rod is fixed to the top of the sliding insulation plate through the end of the retraction connecting rope to form a transmission structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are: When the industrial furnace with dust treatment structure needs to clean the dust, the rotary drive motor is directly started and the inclined plate is moved left and right by rotating the retraction rod. At this time, the processing placement box will synchronously contact the side contact springs on the left and right sides. During this process, the dust in the processing placement box will fall down and be collected. This design makes the cleaning operation of the equipment very convenient and efficient, and can quickly complete the dust cleaning work when performing high-intensity work. Furthermore, while the retractable rod rotates, the retractable connecting rope fixed on the outer surface is stably retracted. The retraction of the retractable connecting rope will synchronously drive the sliding insulation plate upward along the lifting roller frame. This design eliminates the need to open the entire equipment when the finished product needs to be removed, so that the preheating operation is not required for the next operation. This design makes the equipment more energy-efficient and improves its utilization efficiency. Furthermore, the material conveying port is designed with its lower opening directly above the processing and placement box. This design makes the equipment more efficient and stable to use, and prevents raw material spillage, thus reducing the cost of using the equipment. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to Figure 2 , Figure 3 and Figure 4 This utility model provides the following technical solution: an industrial furnace with a dust treatment structure, including a bottom support 1, a furnace processing box 2 installed above the bottom support 1, and an elastic dust removal mechanism installed inside the furnace processing box 2 to swing the processing placement box 12. The elastic dust removal mechanism includes a rotary drive motor 3, such as... Figure 3 As shown, the rotary drive motor 3 is fixedly installed on the upper surface of the bottom support 1. The outer surface of the output end of the rotary drive motor 3 is equipped with a rotary retraction rod 4, and the outer surface of the rotary retraction rod 4 is equipped with a transmission connection mechanism for raising and lowering the sliding insulation plate 7.

[0019] like Figure 2 , Figure 3 and Figure 4 The technical solution shown addresses the problem that existing designs for dust removal are complex and inefficient, failing to quickly complete dust removal during high-intensity work. It discloses the following: a rotating retractable rod 4 is mounted on the outer surface of the output end of the rotary drive motor 3; swing limit frames 11 are mounted on both sides of the inner surface of the bottom support 1; the lower sides of the processing placement box 12 slide along the interior of the swing limit frames 11; and lateral contact springs 13 are mounted on the inner surface of the furnace processing box 2, with the ends of the lateral contact springs 13 contacting the corresponding left and right sides of the processing placement box 12. Figure 4As shown, a limiting bite rod 15 is installed on the inner surface of the bottom support 1, and an inclined driving plate 14 is installed on the outer surface of the limiting bite rod 15. The top of the inclined driving plate 14 is designed with an incline. The rotation trajectory of the rotating retraction rod 4 abuts against the top incline of the inclined driving plate 14. The inclined driving plate 14 slides along the outside of the limiting bite rod 15. The lower end of the inclined driving plate 14 abuts against the inside of the processing placement box 12. Two sets of swing limiting frame 11 and side contact spring 13 are symmetrically installed about the center point of the processing placement box 12.

[0020] When cleaning the dust inside the processing box 12 is required, first start the rotary drive motor 3 fixedly installed on the top of the furnace processing box 2. At this time, the rotary drive motor 3 will synchronously drive the rotating retractable rod 4 fixedly installed on the outer surface of its output end to rotate. While the rotating retractable rod 4 is rotating, it will contact the top of the inclined drive plate 14. Because the contact surface between the inclined drive plate 14 and the rotating retractable rod 4 is inclined, the inclined drive plate 14 will slide laterally and stably as it contacts the rod. Figure 4 As shown, since the end of the inclined driving plate 14 is engaged and fixed with the inside of the processing placement box 12, the processing placement box 12 will be driven by it to move horizontally synchronously. Since the bottom of the processing placement box 12 is nested and slidably installed inside the swing limit frame 11 fixedly installed inside the bottom support 1, the movement of the processing placement box 12 will be carried out along the inside of the swing limit frame 11. During the left and right swinging operation of the swing limit frame 11, it will abut against the side abutment spring 13 fixedly installed on the side of the bottom support 1. When the rotating retraction rod 4 disengages from the inclined driving plate 14, the processing placement box 12 will be driven in the opposite direction to move synchronously during the reset process of the side abutment spring 13. During the movement of the inclined driving plate 14, it will move along the inside of the limit biting rod 15 fixedly installed inside the bottom support 1. This design makes the use of the equipment more efficient and stable.

[0021] Example 2: Figure 1 , Figure 5 and Figure 6 The technical solution shown addresses the problem that existing designs often require opening the entire device when removing finished products, necessitating repeated preheating for subsequent operations. This design leads to insufficient energy efficiency and the continuous heating process reduces the device's overall efficiency. The solution discloses a transmission connection mechanism including a retractable connecting rope 8, with one end of the rope fixedly mounted on the outer surface of the rotating retractable rod 4, and the other end fixedly mounted on the top of the sliding insulation plate 7. Figure 5As shown, a heat-insulating hollow frame 6 is installed on the outer surface of the output end of the furnace processing box 2. The sliding insulation plate 7 is slidably installed inside the heat-insulating hollow frame 6. The bottom support 1 and the heat-insulating hollow frame 6 are internally connected. Two sets of retractable connecting ropes 8 are symmetrically installed on the left and right sides about the center point of the rotating retractable rod 4. A material conveying port 5 is installed on the top of the furnace processing box 2. The lower opening of the material conveying port 5 corresponds to the installation position of the processing placement box 12. The inner surface of the heat-insulating hollow frame 6 and the outer surface of the sliding insulation plate 7 are in contact to form a sliding structure. The rotating retractable rod 4 is fixed to the top of the sliding insulation plate 7 through the end of the retractable connecting rope 8 to form a transmission structure.

[0022] After the processing operation is completed, when the processing placement box 12 needs to be removed outward, as the rotating retraction rod 4 is driven by the rotary drive motor 3 to rotate, the retraction connecting rope 8 fixedly installed on the outer surface will be driven synchronously to retract inward. At this time, the retraction connecting rope 8 will slide along the top of the lifting roller frame 9 fixedly installed on the upper surface of the bottom support 1, and with the auxiliary drive of the lifting roller frame 9, the sliding insulation plate 7 fixedly installed at the other end of the retraction connecting rope 8 will move upward synchronously. The movement trajectory of the sliding insulation plate 7 will follow the interior of the heat-insulating hollow frame 6 fixedly installed at the corresponding position at the front end of the bottom support 1, such as... Figure 6 As shown, as the sliding insulation plate 7 rises continuously inside the heat-insulating hollow frame 6, the opening of the furnace processing box 2 can be opened, allowing the processing placement box 12 to be directly removed. After the installation of the processing placement box 12 is completed, the sliding insulation plate 7 can be reset and insulated by rotating the retracting rod 4 in the opposite direction. Since the sliding limit position of the sliding insulation plate 7 corresponds to the height of the processing placement box 12, most of the heat inside the equipment is retained after opening. When raw materials need to be placed into the processing placement box 12, they can be placed directly through the material conveying port 5 designed at the top of the bottom support 1. At the same time, the dust generated by the swing of the processing placement box 12 can be collected through the dust collection auxiliary port 10 fixed at the bottom of the furnace processing box 2, making the use of the equipment more convenient and efficient.
