Description

Technical Field

[0001] The invention belongs to the technical field of baking furnaces, and in particular relates to a flue cleaning structure and a flue of a prebaked anode baking furnace. Background Art

[0002] A roasting furnace is a roasting equipment that completes a certain chemical reaction at a temperature lower than the melting temperature of the material. It is a commonly used equipment for preparing furnace charges. Most of the materials in the roasting furnace are always in a solid state. Therefore, the roasting temperature of the roasting furnace must be limited to ensure that the materials do not melt significantly. The most common roasting furnace is the roasting furnace used in metal smelting, which is used to heat or burn impurities in ores and other metal-containing substances. It can significantly reduce the sintering temperature and greatly reduce the operating energy consumption of the machine during the processing. During the processing of the roasting furnace, roasting flue gas impurities will be generated, which will enter the flue gas duct through the flue gas outlet and then be discharged from the flue for subsequent emission treatment.

[0003] Among the existing patents, CN212901569U discloses a roaster flue structure that is easy to clean regularly, including a roaster flue main body, a cleaning pipe is installed on the outside of the top of the roaster flue main body, and a sealing top cover is connected to the outside of the top of the cleaning pipe, the sealing top cover and the two sides of the outer wall of the cleaning pipe are respectively connected with hydraulic hinges and sealing lock buckles, avoidance through holes are opened inside the two sides of the top of the sealing top cover, and the avoidance through holes are connected through the inside of the telescopic push rod body, a supporting column is installed on the outside of the top of the cleaning pipe, and a fixed table is connected to the top of the supporting column, an electric push rod main unit is installed on both sides of the top of the fixed table, and the bottom of the electric push rod main unit is externally connected to the telescopic push rod body. The roaster flue structure that is easy to clean regularly can effectively reduce the smoke from entering the cleaning pipe, avoid the situation that the cleaning pipe affects the smoke circulation and the dust accumulates on the inner wall, and facilitates subsequent cleaning.

[0004] The above scheme collects dust inside the flue through the flue cleaning pipe, which can facilitate subsequent disassembly and collection and treatment. However, when the roasting furnace flue discharges flue gas, the high temperature inside the roasting furnace will produce a certain amount of high-temperature water vapor. When the water vapor and flue gas enter the flue together, the temperature inside the flue pipe is reduced, so it will be transported forward with the flue gas. The water vapor will gradually carry the dust and ash to the inside of the flue, and the dust will adhere to the inner wall of the pipe. Therefore, it cannot be collected and treated by the above scheme, and it is still necessary to enter the pipe regularly for cleaning. Due to the limited space inside the pipe, it is cumbersome to clean, and it is impossible to clean the pipe regularly and efficiently, which affects the fluency of flue gas emission. Summary of the invention

[0005] The purpose of the present invention is to provide a flue cleaning structure and flue of a prebaked anode baking furnace, which can scrape and clean the dust and ash attached to the inner wall of the flue, facilitate cleaning the inside of the flue at any time, ensure the cleanliness of the inner wall of the flue, and ensure stable and efficient transportation of the flue.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a flue cleaning structure of a pre-baked anode baking furnace, comprising a cleaning mechanism for cleaning the flue, a driving assembly and two movable assemblies, wherein the cleaning mechanism is slidably arranged inside the flue;

[0007] The cleaning mechanism comprises a movable plate, a circular opening is formed through the center of the movable plate, outer plates are fixedly connected to the side walls of the movable plate near the circular opening, cleaning scraper frames are fixedly connected to the edges of the two outer plates away from each other, a collecting groove is formed in the inner position of the movable plate near the outer arc of the circular opening, an air extractor is installed in the collecting groove, and an air extraction plate is fixedly connected to the side wall of the movable plate near the outer side of the circular opening;

[0008] The driving component is installed on the outside of the flue, and the two movable components are respectively installed at the middle positions of the top and bottom of the moving plate, and the driving component and the movable components are arranged to be electromagnetically attracted to each other.

[0009] As a preferred solution of the present invention, the air extractor is fixedly connected with dust suction pipes on both sides of the air extraction plate, the dust suction pipes are connected through the side wall of the movable plate, the outer end of the dust suction pipes is connected to the air extraction plate, and a dust outlet is provided on one side wall of the air extractor.

[0010] As a preferred solution of the present invention, a processing port is provided at the bottom of the movable plate, a baffle is rotatably connected to the inner side of the processing port, and the baffle and the processing port are adapted to each other, so that the collected dust can be processed conveniently from the processing port.

[0011] As a preferred solution of the present invention, dustproof plates are fixedly connected to both ends of the movable plate near the circular opening, and the dustproof plates are provided with the same openings at positions opposite to the circular opening. The dustproof plates make dust suction and collection more stable.

[0012] As a preferred solution of the present invention, the driving assembly includes two moving blocks and four linear motor tracks. The moving blocks are provided with track grooves at the bottom. The linear motor tracks and the track grooves are adapted to slide with each other, so as to facilitate the operation of the driving assembly.

[0014] As a preferred embodiment of the present invention, the movable component includes a base, and bottom blocks are fixedly connected to the middle positions of the two opposite sides of the base. A top rod is slidably connected to the side of the bottom block away from the base, and a magnetic plate is fixedly connected to the top of the top rod.

[0015] As a preferred solution of the present invention, a spring is fixedly connected to one end of the bottom of the top rod, and the other end of the spring is fixedly connected to the relative inner groove wall of the bottom block and the top rod, and both ends of the base are provided with openings, and the inner side of the opening is rotatably connected to a roller. The spring and the top rod facilitate the rebound and reset of the magnetic suction plate, which fits the inner wall of the flue, and prevents the cleaning mechanism from sliding without reason. When the cleaning mechanism moves, the roller can improve the smoothness of movement.

[0016] A roasting furnace flue comprises two flange sections and a plurality of middle sections.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0035] Embodiment 1

[0036] like Figure 1-10 As shown, this embodiment provides a flue cleaning structure for a pre-baked anode baking furnace, including a cleaning mechanism 2 for cleaning the flue 1, a driving component 3 and two movable components 4. The cleaning mechanism 2 is slidably arranged inside the flue 1. The cleaning mechanism 2 can move back and forth, and can clean the inside of the flue 1 while moving. The inner wall of the flue 1 can be cleaned conveniently, efficiently and fully, thereby improving the cleaning effect inside the flue 1 of the baking furnace.

[0037] The cleaning mechanism 2 includes a movable plate 21, a circular opening 22 is opened through the center of the movable plate 21, and the side walls of the movable plate 21 on both sides of the opening close to the circular opening 22 are fixedly connected with outer plates 211, and the edges of the two outer plates 211 away from each other are fixedly connected with cleaning scraper frames 23, and the cleaning scraper frames 23 are in contact with the inner wall of the flue 1.

[0038] By moving the cleaning scraper frame 23 inside the flue 1, the attachments on the inner wall of the flue 1 are scraped off, and efficient and stable multiple reciprocating cleaning is achieved, thereby improving the effect of the cleaning structure on cleaning the inside of the flue 1; reciprocating cleaning can ensure that the attachments inside the flue 1 are cleaned up, so the exhaust gas inside the flue 1 will not be affected by the blockage of the attachments, so that the roasting furnace can discharge waste gas more stably during the combustion process.

[0039] A collecting groove 24 is provided at the inner position of the movable plate 21 near the outer arc of the circular opening 22, and an exhaust fan 25 is installed in the collecting groove 24. An exhaust plate 253 is fixedly connected to the side wall position of the movable plate 21 near the outer side of the opening of the circular opening 22. Through the exhaust plate 253 and the exhaust fan 25, the waste dust generated by cleaning can be conveniently collected and processed in a centralized manner, thereby improving the convenience of cleaning.

[0040] The driving component 3 is installed on the outside of the flue 1, and the two movable components 4 are respectively installed at the middle position of the top and bottom of the movable plate 21. The driving component 3 and the movable component 4 are electromagnetically attracted to each other. The driving component 3 and the movable component 4 utilize the magnetic repulsion effect of the same poles of magnetic attraction to achieve a magnetic levitation movement effect, which makes it convenient to use the driving component 3 to drive the movable component 4 to move from the outside, thereby realizing the movement of the cleaning mechanism 2 from the outside.

[0041] The exhaust fan 25 is fixedly connected with a dust suction pipe 251 on both sides of the exhaust plate 253. The dust suction pipe 251 is connected to the side wall of the movable plate 21, and the outer end of the dust suction pipe 251 is connected to the exhaust plate 253. A dust outlet 252 is provided on one side wall of the exhaust fan 25. When the cleaning scraping frame 23 of the cleaning mechanism 2 cleans and scrapes the inside of the flue 1, the exhaust fan 25 can be started. The exhaust fan 25 collects the scraped dust through the dust suction pipe 251 and the exhaust plate 253, and then transports it through the dust suction pipe 251 of the exhaust fan 25, and then discharges it into the collection tank 24 through the dust outlet 252, so as to collect the waste dust after the flue 1 is cleaned.

[0042] Embodiment 2

[0043] See also Figure 2 and Figure 5 , further improvements were made on the basis of Example 1:

[0044] A processing port 26 is provided at the bottom of the movable plate 21, and a baffle 261 is rotatably connected to the inner side of the processing port 26. The baffle 261 and the processing port 26 are adapted to each other. By rotating the opened baffle 261, the cleaning mechanism 2 can be conveniently moved out of the flue 1 after cleaning, and then the baffle 261 of the cleaning mechanism 2 is opened, so that the dust collected in the collection tank 24 can be taken out from the processing port 26 for further processing.

[0045] Dust-proof plates 27 are fixedly connected to both ends of the movable plate 21 near the circular opening 22. The same through openings are opened on the dust-proof plates 27 relative to the circular opening 22. When the cleaning scraper frame 23 is attached to the inner wall of the flue 1 for scraping and cleaning, the cleaned dust is collected and processed by the above-mentioned vacuum collection; when the cleaning scraper frame 23 is scraping and cleaning the inner wall of the flue 1, the vacuum structure collects the dust by vacuum. At this time, the dust-proof plates 27 are used to block the dust to prevent it from floating out of the vacuum position, thereby ensuring the stability of the vacuum collection.

[0046] Embodiment 3

[0047] See also Figure 2-4 and Figure 7 , further improvements were made on the basis of Example 1:

[0048] The driving assembly 3 includes two moving blocks 31 and four linear motor rails 33. A rail groove 34 is provided at the bottom of the moving block 31. The linear motor rail 33 and the rail groove 34 are adapted to slide with each other. An electromagnetic block 32 is fixedly connected to the middle position of the opposite side of the two moving blocks 31. A connecting plate 35 is fixedly connected between the opposite ends of the two moving blocks 31. The connecting plate 35 enables the upper and lower moving blocks 31 to move more stably and synchronously, thereby ensuring the stable movement of the cleaning mechanism 2.

[0049] The movable component 4 includes a base 41, and the middle positions of the two opposite sides of the bases 41 are fixedly connected with a bottom block 42, and the side of the bottom block 42 away from the base 41 is slidably connected with a top rod 421, and the top of the top rod 421 is fixedly connected with a magnetic plate 43, and one end of the bottom of the top rod 421 is fixedly connected with a spring 422, and the other end of the spring 422 is fixedly connected with the relative inner groove wall of the bottom block 42 and the top rod 421. Both ends of the base 41 are provided with openings, and the inner side of the opening is rotatably connected with a roller 44. Through the roller 44, during the movement of the movable component 4, an auxiliary rolling movement effect is provided for the cleaning mechanism 2, so that the cleaning mechanism 2 can move stably and smoothly.

[0050] When it is necessary to move and clean the inside of the flue 1, by starting the linear motor track 33, the moving block 31 slides linearly on the linear motor track 33 through the track groove 34, and the electromagnetic block 32 is started at the same time. The electromagnetic block 32 generates a magnetic force with the same magnetic pole as the magnetic suction plate 43, pushing the magnetic suction plate 43 to move to one side of the bottom block 42. During the process, the top rod 421 slides toward the inner groove at the outer wall position of the bottom block 42, and squeezes the spring 422 to contract, and then the moving block 31 moves. At this time, the electromagnetic block 32 can drive the magnetic suction plate 43 to move. Here, referring to the principle of magnetic levitation that like charges repel each other, the electromagnetic block 32 is energized to generate a magnetic field with the same magnetic pole as the magnetic suction plate 43, and then the two repel each other, so that the electromagnetic block 32 can drive the magnetic suction plate 43 to move synchronously, and the moving speed depends on the instantaneous repulsive force strength of the magnetic suction plate 43. The greater the strength, the faster the speed.

[0051] The cleaning mechanism 2 is driven to move by the base 41 to clean the flue 1. During the cleaning process, the roller 44 rotating on the base 41 improves the stability of the movement of the cleaning mechanism 2. When the cleaning is finished, the electromagnetic block 32 turns off the magnetization. At this time, the spring 422 can rebound to push the top rod 421 and the magnetic plate 43 to return to contact the inner wall of the flue 1, so that the cleaning mechanism 2 cannot move at will.

[0052] Embodiment 4

[0053] See also Figure 1 , 8 and Fig. 9 A roasting furnace flue, the flue 1 includes two flange sections 11 and a plurality of middle sections 12, the flange section 11 is a flange fixed at one end for connection, the flange is provided with bolt holes for fixing, the flue 1 has a pipe shape of a rectangle or a circle, preferably a rectangle, and the flue 1 is made of stainless steel.

[0054] The two opposite ends of the two flange sections 11 and the two ends of the middle section 12 are provided with card slots 13, and each two opposite card slots 13 are adapted to be carded with an assembly frame 131, and the edge positions of the opposite sides of the two ends of the assembly frame 131 are fixedly connected with fixing ears 134, and bolt holes are provided through the fixing ears 134, and the two opposite fixing ears 134 are fixed by bolts, and the four linear motor tracks 33 are detachably installed in pairs between the two flange sections 11. The linear motor track 33 is an application of the prior art, and will not be described in detail here. The two ends of the linear motor track 33 are respectively connected to the side walls of the flanges of the flange sections 11 at the two ends, and there are gaps between the linear motor track 33 and the surfaces of the flange sections 11 and the middle section 12. Through the setting of the gaps, the electromagnetic block 32 is set at a position outside the fixing ears 134, ensuring that the moving block 31 of the drive assembly 3 can move outside the flue 1 without being blocked.

[0055] A sealing strip 133 is fixedly connected to the inner side of the assembly frame 131, and a sealing groove 132 is provided near the inner side of the slot 13 and opposite to the sealing strip 133 on the flange section 11 and the middle section 12, and the sealing strip 133 and the sealing groove 132 are adapted and plugged in each other. The smoke duct of the roasting furnace is assembled by the flange section 11 and the middle section 12, and the middle section 12 is aligned with each other or with the end of the flange section 11, and the two halves of the slot 13 form a complete state, and then the assembly frame 131 is aligned with the slot 13 and inserted, and the two fixing ears 134 are opposite at this time, and the two fixing ears 134 are fixed by bolts at the same time. In the above assembly process, when the assembly frame 131 is inserted into the slot 13, the sealing strip 133 and the sealing groove 132 are adapted and plugged in each other to form a multi-channel sealing structure to ensure the sealing of the pipeline connection.

[0056] Because the flue 1 of the roasting furnace is inevitably aged after long-term use, or the interior needs to be repeatedly repaired and cleaned, the flue 1 can be separated into sections through the above-mentioned segmented assembly method of the flue 1, and can be disassembled and assembled separately, which is convenient for the disassembly, assembly and replacement of the flue 1 and makes subsequent cleaning and maintenance more convenient.
