AI Technical Summary
The soot generated by the existing preheated industrial furnaces during combustion easily adheres to the surface of the smoke exhaust pipe, causing the pipe to narrow and increase the cleaning burden for staff.
A preheated industrial furnace with a filter plate, a rotating rod and a cleaning rod is designed to filter smoke and dust through the filter plate. The rotating rod drives the cleaning rod to brush the bottom of the filter plate. The smoke and dust fall into the collection box through unopened mesh holes, reducing the adhesion of smoke and dust, and the baffle blocks wind force, and dust is collected into the collection box.
It effectively reduces the adhesion of smoke and dust on the inner wall of the smoke exhaust pipe, reduces the cleaning burden of staff, and improves the safety and operation convenience of equipment.

DETAILED DESCRIPTION
[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The function of the accompanying drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, it should not be construed as a limitation on the protection scope of the present utility model.
[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution: a preheating industrial furnace with high safety, including an industrial furnace 5. A smoke exhaust pipe 6 is fixedly connected to the surface of the industrial furnace 5. A connecting pipe 2 is fixedly connected to the surface of the industrial furnace 5. One end of the connecting pipe 2 away from the industrial furnace 5 is fixedly connected to a fixed shell 1. A filter plate 10 is fixedly connected to the inner wall of the industrial furnace 5, and one-fourth of the filter plate 10 is not provided with mesh holes. Through the setting of the filter plate 10, the smoke and dust generated by combustion inside the industrial furnace 5 are filtered, reducing the situation where smoke and dust adhere to the inner wall of the smoke exhaust pipe 6. At the same time, it avoids the later cleaning of the surface of the smoke exhaust pipe 6 by the staff, reducing the labor burden of the staff.
[0024] A heater and a blower are arranged inside the fixed shell 1. The air sent into the industrial furnace 5 by the blower is preheated by the heater. The heater and the blower are existing structures and will not be explained further.
[0025] A rotating rod 11 is rotatably connected to the inside of the filter plate 10. A first cleaning rod 12 is fixedly connected to the surface of the rotating rod 11. A turbine blade 8 is fixedly connected to the surface of the rotating rod 11. A baffle 13 is fixedly connected to the inner wall of the industrial furnace 5, and the baffle 13 is inclined. A collection box 7 is fixedly connected to the surface of the industrial furnace 5. A through groove 18 is opened on the surface of the collection box 7, and the through groove 18 penetrates into the inside of the industrial furnace 5. The collection box 7 is in communication with the inside of the industrial furnace 5.
[0026] When the fixed shell 1 is started to preheat and warm the air inside it, the hot air entering the industrial furnace 5 blows the turbine blade 8. The turbine blade 8 drives the rotating rod 11 to rotate. The rotating rod 11 drives the first cleaning rod 12 to rotate. The first cleaning rod 12 rotates to brush the bottom surface of the filter plate 10. Then, the smoke and dust filtered on the bottom surface of the filter plate 10 rotate with the first cleaning rod 12. Since one-fourth of the filter plate 10 is not provided with mesh holes, when the smoke and dust move to the part of the filter plate 10 without mesh holes along with the first cleaning rod 12, at the same time, the baffle 13 blocks the upward blowing wind, and then the dust falls onto the surface of the baffle 13. And the baffle 13 is set to be inclined, and the fallen dust will enter the inside of the collection box 7 through the through groove 18 along the inclined surface of the baffle 13, collecting the smoke and dust on the bottom surface of the filter plate 10, avoiding the regular cleaning of the filter plate 10 by the staff and facilitating the subsequent treatment of the smoke and dust by the staff.
[0027] A heat insulating layer 4 is fixedly connected to the surface of the industrial furnace 5 . The heat insulating layer 4 is used to isolate the heat emitted by the industrial furnace 5 and prevent workers from getting burned when touching the industrial furnace 5 .
[0028] An observation window 3 is fixedly connected to the surface of the industrial furnace 5, a fixed block 17 is fixedly connected to the inner wall of the industrial furnace 5, a sliding rod 14 is slidably connected inside the fixed block 17, one end of the sliding rod 14 is fixedly connected to the sliding block 15, and the sliding block 15 is arranged in an inclined state, and one end of the sliding rod 14 away from the sliding block 15 is fixedly connected to a cleaning rod 16, a spring 19 is movably sleeved on the surface of the sliding rod 14, and both ends of the spring 19 are fixedly connected to the sliding rod 14 and the fixed block 17 respectively, and a toggle rod 9 is fixedly connected to the surface of the rotating rod 11.
[0029] When the rotating rod 11 rotates, the rotating rod 11 drives the toggle rod 9 to rotate, and due to the setting of the inclined surface of the sliding block 15, the toggle rod 9 rotates to squeeze the sliding block 15, the sliding block 15 drives the sliding rod 14 to move, the sliding rod 14 drives the cleaning rod 16 to move, and the cleaning rod 16 moves to brush the surface of the observation window 3, thereby avoiding smoke and dust from adhering to the surface of the observation window 3, making it convenient for the staff to observe the interior of the fixed shell 1 through the observation window 3, and facilitating the use of the staff.
[0030] Working principle: The turbine blades 8 drive the rotating rod 11 and the cleaning rod 12 to rotate. The cleaning rod 12 rotates to brush the bottom surface of the filter plate 10, and then the smoke filtered on the bottom surface of the filter plate 10 rotates with the cleaning rod 12. When the smoke moves with the cleaning rod 12 to the filter plate 10 where there is no mesh, the dust falls onto the surface of the baffle 13. The fallen dust will follow the inclined surface of the baffle 13 through the through groove 18 to the inside of the collection box 7, and the smoke on the bottom surface of the filter plate 10 is collected.
[0031] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
