Description

Technical Field

[0001] This utility model relates to the field of industrial furnace technology, and in particular to an industrial furnace capable of dust removal. Background Technology

[0002] An industrial furnace is a device used to heat workpieces. It is widely used in many industrial fields such as steel, metallurgy, petroleum, chemical, aerospace, and food. Industrial furnaces can be divided into many types according to their working principle, fuel type, and thermal regime, such as electric resistance furnaces, heat treatment furnaces, and oil-fired furnaces.

[0003] Chinese patent provides an industrial furnace with good dust removal effect, publication number CN212585507U, which includes a dust removal box fixedly installed on the outside of the industrial furnace. An incomplete worm gear and a worm wheel are rotatably installed on the top inner side of the dust removal box. The incomplete worm gear and the worm wheel mesh with each other. A gear is fixedly installed on the rear side of the worm wheel. A rack meshes with the bottom of the gear. The bottom of the rack is slidably installed on the inner wall of the dust removal box. The top of a vertical rod is fixedly installed on one side of the bottom of the rack.

[0004] The aforementioned industrial furnace can spray water through multiple water nozzles, which will form a mist to spray the smoke and filter out the dust in the smoke. However, when the device is in use, oxides and dust will adhere to the inner wall of the smoke pipe. As oxides and dust continue to accumulate on the inner wall of the smoke pipe, they are prone to caking and clogging the smoke pipe. Utility Model Content

[0005] The main objective of this invention is to provide an industrial furnace capable of dust removal, which can effectively solve the technical problem in the background art where oxides and dust adhere to the inner wall of the smoke pipe, and as oxides and dust continuously accumulate on the inner wall of the smoke pipe, they easily clump together.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An industrial furnace capable of dust removal includes a furnace body, an exhaust pipe fixedly installed on the top of the furnace body, a fan fixedly installed at one end of the exhaust pipe, two support frames fixedly installed at the bottom of the fan, one end of the two support frames being fixedly connected to the outer wall of the furnace body, and a return air pipe fixedly installed at one end of the fan.

[0008] As a further embodiment of this utility model, four fixing brackets are fixedly installed on the inner wall of the exhaust pipe, and the inner walls of the two front fixing brackets are rotatably connected to a first connecting rod.

[0009] As a further embodiment of this utility model, the inner walls of the two rear fixed brackets are rotated and connected to a second connecting rod, and the bottom of the inner wall of the exhaust pipe is rotatably connected to a third connecting rod, with a blade fixedly installed at one end of the third connecting rod.

[0010] As a further embodiment of this utility model, a first bevel gear is fixedly installed at one end of the first connecting rod and on the outer wall of the third connecting rod, and a second bevel gear is fixedly installed at both the upper and lower ends of the second connecting rod, and the second bevel gear meshes with the first bevel gear.

[0011] As a further embodiment of this utility model, a first actuating plate is fixedly installed on the outer wall of the first connecting rod, and a second actuating plate is fixedly installed on the outer wall of the second connecting rod.

[0012] As a further embodiment of this utility model, a filter screen is fixedly installed at the front end of the return gas pipe, and a connecting pipe is fixedly installed at the front end of the filter screen, with one end of the connecting pipe fixedly connected to the outer wall of the furnace body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This dust-removing industrial furnace uses a fan to draw air through the exhaust pipe, sucking oxides and dust from the furnace body into the exhaust pipe and then discharging them into the return air pipe. During the air intake process, the fan blades rotate, which in turn causes the third connecting rod and the first bevel gear to rotate. Due to the meshing connection between the second and first bevel gears, the rotation of the first bevel gear drives the second bevel gear to rotate, which in turn causes the second connecting rod to rotate. This, in turn, causes the first and second actuating plates to rotate, which can remove oxides and dust adhering to the inner wall of the exhaust pipe, preventing the formation of clumps and preventing a large amount of oxides and dust from accumulating and clogging the exhaust pipe.

[0015] 2) In this dust-removing industrial furnace, the exhaust port of the fan discharges the inhaled oxides and dust into the return air pipe, and filters them through the filter screen, so that clean air is injected into the furnace body through the connecting pipe, thus avoiding a significant drop in the temperature inside the furnace body.

[0021] 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.

[0022] Example 1

[0023] Combination Figures 1-4 An industrial furnace capable of dust removal includes a furnace body 1, with an exhaust pipe 2 fixedly installed on the top of the furnace body 1.

[0024] See Figure 1 and Figure 2 Furthermore, it is found that a fan 3 is fixedly installed at one end of the exhaust pipe 2, and two support frames 4 are fixedly installed at the bottom of the fan 3. One end of the two support frames 4 is fixedly connected to the outer wall of the furnace body 1. A return gas pipe 5 is fixedly installed at one end of the fan 3. Four fixed frames 6 are fixedly installed on the inner wall of the exhaust pipe 2. The inner walls of the two front fixed frames 6 are rotatably connected to the first connecting rod 7. The inner walls of the two rear fixed frames 6 are rotatably connected to the second connecting rod 8. The bottom of the inner wall of the exhaust pipe 2 is rotatably connected to the third connecting rod 9. One end of the third connecting rod 9 is fixedly installed with a blade 10.

[0026] Example 2

[0027] See Figure 3 and Figure 4Furthermore, based on Embodiment 1, a first bevel gear 11 is fixedly installed on one end of the first connecting rod 7 and the outer wall of the third connecting rod 9. A second bevel gear 12 is fixedly installed on both the upper and lower ends of the second connecting rod 8, and the second bevel gear 12 meshes with the first bevel gear 11. A first actuating plate 13 is fixedly installed on the outer wall of the first connecting rod 7, and a second actuating plate 14 is fixedly installed on the outer wall of the second connecting rod 8.

[0029] During actual operation, oxides are generated when the workpiece is heated in an industrial furnace, and the dust attached to the workpiece will float to the surface after being heated at high temperature. The operator starts the blower 3, which draws air through the exhaust pipe 2, sucking the oxides and dust from the furnace body 1 into the exhaust pipe 2, and then into the return air pipe 5. During the air intake process, the blower 3 will cause the blades 10 to rotate, which in turn will cause the third connecting rod 9 and the first bevel gear 11 to rotate. Due to the meshing connection between the second bevel gear 12 and the first bevel gear 11, when the first bevel gear 11 rotates, it will drive the second bevel gear 12 to rotate, which will cause the second connecting rod 8 to rotate, and the first connecting rod 7 to rotate, which will in turn cause the first actuating plate 13 and the second actuating plate 14 to rotate. The exhaust port of the blower 3 will discharge the sucked-in oxides and dust into the return air pipe 5, and filter them through the filter screen 15, so that clean air is injected into the furnace body 1 through the connecting pipe 16.
