A cleaning device for hot pressing sintering furnace

Abstract

The present invention is applicable to the technical field of cleaning devices, and provides a cleaning device for a hot pressing sintering furnace, comprising an adjustment component, a displacement component installed on the top of the adjustment component, and a cleaning component arranged at one end of the displacement component away from the adjustment component. The device solves the problem that the existing device cannot clean the circular surface of the inner wall of the sintering furnace. In addition, the cleaning device is prone to cause the scraped slag to be pushed into a deeper position in the furnace and is difficult to be discharged in the process of gradually penetrating into the interior of the sintering furnace. The device cleans the circumferential surface and circular surface of the inner wall of the sintering furnace respectively by arranging a side wall cleaning mechanism and a bottom surface cleaning mechanism, and the slag slides through the gap between the two L-shaped plates when it falls. Multiple cleaning plates extend beyond the outer wall of the cleaning disk, and the diameter of the cleaning disk is smaller than the inner diameter of the sintering tube. Therefore, the slag scraped by the cleaning plate can slide through the gap between the cleaning disk and the inner wall of the sintering tube, thereby alleviating the situation where the slag is pushed into the interior of the sintering tube.

Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, and more particularly to a cleaning device for a hot pressing sintering furnace. Background Art

[0002] The hot pressing sintering furnace uses induction heating to carry out protective sintering of the heated objects. Under vacuum or protective atmosphere conditions, the principle of medium-frequency induction heating is used to press and sinter various metal powders.

[0003] When the hot pressing sintering furnace is opening and closing the furnace door, the airflow in the furnace will be disturbed, causing powder materials to fly up in the furnace. After the powder flies up, it sticks to the inner wall of the furnace. Through the high-temperature sintering of the sintering furnace, the powder adhered to the inner wall of the furnace solidifies to form slag. In order to prevent the accumulation of slag from affecting the sintering of powder, currently, the staff is required to regularly inspect and clean the sintering furnace. When cleaning, the staff sucks out the powder in the sintering furnace with a vacuum cleaner. However, after the slag sticks to the inner wall of the furnace, the adhesion strength is high, so it is not easy to be sucked out. In order to achieve the purpose of cleaning the adhered slag, the staff uses a cleaning device to scrape off the slag, that is, the external cleaning sheet is pressed against the inner wall of the sintering furnace, and the external cleaning sheet is driven to move along the inner wall of the furnace, thereby scraping off the adhered slag.

[0004] However, this method can only clean the circumferential surface of the inner wall of the sintering furnace, while the circular surface of the inner wall of the sintering furnace cannot be cleaned. In addition, the cleaning device continues to go deeper into the furnace to clean the slag in the sintering furnace. However, the cleaning device gradually goes deeper, which can easily cause the scraped slag to be pushed deeper into the furnace, which not only makes it difficult to discharge the slag from the inside of the sintering furnace, but also aggravates the accumulation of slag in the sintering furnace. Summary of the invention

[0005] In view of the shortcomings of the prior art, the object of the present invention is to provide a cleaning device for a hot pressing sintering furnace.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a cleaning device for a hot pressing sintering furnace, comprising an adjustment component, a displacement component installed on the top of the adjustment component, and a cleaning component arranged at one end of the displacement component away from the adjustment component, a sintering mechanism is arranged on one side of the adjustment component, the cleaning component is arranged toward the sintering mechanism, a discharge component is installed on the outer side wall of the displacement component, a collection box is arranged on the top of the adjustment component, and one end of the discharge component is connected to the collection box.

[0007] The cleaning assembly comprises a driving mechanism installed inside the displacement assembly and a side wall cleaning mechanism connected to the output end of the driving mechanism, and a bottom surface cleaning mechanism is installed at one end of the side wall cleaning mechanism away from the driving mechanism.

[0008] The sintering mechanism comprises a bracket arranged on one side of the adjusting component and a sintering cylinder installed on the top of the bracket, and the cleaning component is coaxially arranged with the sintering cylinder.

[0009] The discharge assembly includes an adjustment mechanism installed on the outer wall of the displacement assembly and a discharge hose installed on the adjustment mechanism. One end of the discharge hose passes through the interior of the displacement assembly and is connected to the collection box. The outer wall of the driving mechanism is connected to a shunt pipe, and the inner diameter of the shunt pipe is adapted to the outer diameter of the discharge hose. One end of the driving mechanism away from the displacement assembly passes through the interior of the side wall cleaning mechanism and is connected to a conical suction head, and the conical suction head is arranged toward the sintering cylinder.

[0010] The present invention is further configured as follows: the displacement assembly includes a support tube installed on the top of the adjustment assembly and three fixed plates equidistantly connected to the outer wall of the support tube, the side walls of the three fixed plates are each provided with a through groove, a displacement cylinder is hingedly installed on a side of each fixed plate away from the support tube, a piston rod of the displacement cylinder is connected to a slider, and the slider is slidably connected to the inside of the corresponding through groove, a track transmission mechanism is provided at one end of each fixed plate away from the displacement cylinder, a first connecting rod is hingedly connected between the track transmission mechanism and the corresponding fixed plate, a second connecting rod is hingedly connected between the track transmission mechanism and the corresponding slider, and a driving motor for driving is installed on the side wall of each track transmission mechanism.

[0011] The present invention is further configured as follows: the side wall cleaning mechanism includes a connecting pipe arranged at one end of the support tube away from the adjustment assembly, the connecting pipe is coaxially arranged with the support tube, the outer side wall of the connecting pipe is sleeved and connected with two connecting flanges, and the side wall of each connecting flange is equidistantly connected with multiple L-shaped plates.

[0012] The present invention is further configured as follows: the bottom surface cleaning mechanism includes a cleaning disc connected to one end of the connecting tube away from the supporting tube, a plurality of cleaning plates are connected around one side of the cleaning disc away from the connecting tube, and the cleaning plates are arranged toward the sintering cylinder.

[0013] The present invention is further configured as follows: each of the cleaning plates is equidistantly arranged around the axis of the cleaning disk in a clockwise direction, and the cleaning plates are arc-shaped and curved in a clockwise direction.

[0014] The present invention is further configured as follows: the driving mechanism includes a servo motor installed inside the support tube, the output end of the servo motor is connected to the driving tube, the driving tube is coaxially arranged with the support tube, and the end of the driving tube away from the servo motor sequentially passes through the interior of the connecting tube and the center of the cleaning disk and is connected to the conical suction head.

[0015] By adopting the above technical scheme, by setting up a side wall cleaning mechanism and a bottom surface cleaning mechanism, the side wall cleaning mechanism first enters the interior of the sintering furnace to clean the circumferential surface. As the cleaning continues to deepen, when the side wall cleaning mechanism penetrates into the deepest position of the circumferential surface of the inner wall of the sintering furnace for cleaning, the cleaning disc and cleaning plate of the bottom surface cleaning mechanism are used to cooperate to achieve slag scraping and cleaning of the circular surface of the inner wall of the sintering cylinder. This setting achieves the purpose of simultaneously cleaning the circumferential surface and circular surface of the inner wall of the sintering furnace.

[0016] The present invention is further configured as follows: the discharge assembly also includes a rubber ring connected to the outer wall of one end of the discharge hose close to the regulating mechanism, and an electric valve is installed on the outer wall of the diversion pipe.

[0017] The present invention is further configured as follows: the adjustment mechanism includes a mounting seat installed on the outer wall of the support tube and a second adjusting cylinder installed inside the mounting seat, the piston rod of the second adjusting cylinder is arranged toward the support tube, and the piston rod of the second adjusting cylinder passes through the mounting seat and is hinged with a mounting plate, the first adjusting cylinder is hingedly installed between the side of the mounting plate away from the second adjusting cylinder and the side wall of the mounting seat, an electric adjustment guide rail is installed on the side of the mounting plate away from the mounting seat, a slide is slidably connected to the electric adjustment guide rail, and the outer wall of the discharge hose is connected to the slide.

[0018] By adopting the above technical scheme, when discharging slag from the horizontal sintering cylinder, the discharge hose is between the support tube and the connecting tube and faces the circumferential surface of the horizontal sintering cylinder. The slag falling onto the circumferential surface of the horizontal sintering cylinder is directly absorbed and discharged through the discharge hose. When cleaning the slag from the vertical sintering cylinder, the first adjusting cylinder is in an extended state, while the second adjusting cylinder is in a contracted state. At this time, the mounting plate and the electric adjusting guide rail are between the support tube and the connecting tube and face the direction of the diversion pipe. At the same time, the electric adjusting guide rail drives the slide and the discharge hose toward the direction of the diversion pipe, so that the discharge hose can be inserted into the interior of the diversion pipe to complete the connection. The slag falling onto the circular surface of the vertical sintering cylinder is absorbed and discharged through the cooperation of the conical suction head, the driving pipe and the discharge hose, so that the cleaning device is compatible with the slag cleaning and slag discharge of horizontal sintering furnaces and vertical sintering furnaces, thereby improving the functionality of the cleaning device.

[0019] The present invention is further configured as follows: the adjustment assembly includes a lifting mechanism, a conveying mechanism is installed on the top of the lifting mechanism, and the support pipe is horizontally installed on the top of the conveying mechanism.

[0021] By adopting the above technical scheme, the electric conveying guide rail slides above the base plate along the extension direction of the rail, thereby adjusting the position of the displacement assembly at the opening of the sintering cylinder, and the displacement assembly is adjusted to a position coaxial with the sintering cylinder through the cooperation of the rail and the lifting mechanism. The displacement assembly is installed on the slide seat at the top of the electric conveying guide rail. When the displacement assembly is coaxial with the sintering cylinder, the slide seat on the electric conveying guide rail drives the displacement assembly to move in the direction of the sintering cylinder, causing the displacement assembly to penetrate into the interior of the sintering cylinder, thereby facilitating the side wall cleaning mechanism and the bottom cleaning mechanism installed on the displacement assembly to perform slag cleaning operations on the inner wall of the sintering cylinder.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] (1) By setting up a side wall cleaning mechanism and a bottom surface cleaning mechanism, the side wall cleaning mechanism first enters the interior of the sintering furnace to clean the circumferential surface. As the cleaning progresses, when the side wall cleaning mechanism reaches the deepest position of the circumferential surface of the inner wall of the sintering furnace for cleaning, the cleaning disc and the cleaning plate of the bottom surface cleaning mechanism cooperate to scrape off the slag and clean the circular surface of the inner wall of the sintering tube. This setting achieves the purpose of cleaning the circumferential surface and the circular surface of the inner wall of the sintering furnace at the same time.

[0024] (2) The slag scraped off from the sintering tube is sucked into the discharge hose through the gas flow path and collected by the collection box. In addition, the scraping and discharge of the slag are carried out simultaneously, which not only achieves the purpose of timely discharge of the slag without the need for manual collection by staff, but also alleviates the situation where the slag is pushed into the sintering tube.

[0025] (3) When discharging slag from a horizontal sintering tube, the discharge hose is between the support tube and the connecting tube and faces the circumferential surface of the horizontal sintering tube. The slag that falls onto the circumferential surface of the horizontal sintering tube is directly absorbed and discharged through the discharge hose. When cleaning the slag from a vertical sintering tube, the adjustment mechanism drives the discharge hose to connect with the diverter pipe. The slag is sucked into the interior of the drive pipe through the conical suction head and is discharged through the diverter pipe and the discharge hose. This makes the cleaning device compatible with the slag cleaning and slag discharge of horizontal sintering furnaces and vertical sintering furnaces, thereby improving the functionality of the cleaning device.

[0026] (4) There is a gap between two adjacent L-shaped plates on the connecting flange. When the slag falls, it slides through the gap between the two L-shaped plates, thereby alleviating the situation where the slag is pushed into the interior of the sintering tube. In addition, multiple cleaning plates extend beyond the outer wall of the cleaning disk, and the diameter of the cleaning disk is smaller than the inner diameter of the sintering tube. Therefore, the slag scraped off by the cleaning plates can slide through the gap between the cleaning disk and the inner wall of the sintering tube, thereby further alleviating the situation where the slag is pushed into the interior of the sintering tube.

[0051] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0052] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0053] See also Figure 1-13 , the present invention provides the following technical solutions:

[0054] Embodiment 1, a cleaning device for a hot pressing sintering furnace, comprises an adjustment component 1, a displacement component 2 is installed on the top of the adjustment component 1, a sintering mechanism 5 is arranged on one side of the adjustment component 1, the adjustment component 1 is used to adjust the position of the displacement component 2, when the sintering mechanism 5 needs to be cleaned, the displacement component 2 is moved to a position opposite to the sintering mechanism 5 through the adjustment component 1, and the specific structure of the sintering mechanism 5 is as follows:

[0055] See also Figure 1 The sintering mechanism 5 includes a bracket 51 arranged on one side of the adjustment component 1 and a sintering cylinder 52 installed on the top of the bracket 51. A furnace door is hingedly installed on the sintering cylinder 52. The powder material is sintered inside the sintering cylinder 52. When the furnace door is opened and closed, air flow disturbance will occur inside the sintering cylinder 52, causing the powder to fly up. Part of the powder will adhere to the inner wall of the sintering cylinder 52. After the powder is sintered, the powder adhered to the inner wall of the sintering cylinder 52 will solidify to form slag.

[0056] The specific structure of adjustment component 1 is as follows:

[0057] See also Figure 1 and Figure 2 The adjustment component 1 includes a lifting mechanism 11, a conveying mechanism 12 is installed on the top of the lifting mechanism 11, and a support pipe 21 is horizontally installed on the top of the conveying mechanism 12. The lifting mechanism 11 can be a scissor-type platform lifter, and the scissor-type rod mechanism is pushed by hydraulic drive to change the angle, so that the platform on the top of the scissor-type platform lifter is adjusted in height in the vertical direction, so that the displacement component 2 is adjusted to a position consistent with the height of the sintering cylinder 52. The conveying mechanism 12 includes a base plate 121 hinged to the top of the lifting mechanism 11 and a track 122 installed on the top of the base plate 121. The top of the track 122 is slidably connected to an electric conveying guide rail 124, and the electric conveying guide rail 124 extends along the track 122. The electric conveying guide rail 124 can slide above the substrate 121 in the same direction, thereby adjusting the position of the displacement component 2 at the opening of the sintering cylinder 52. The track 122 and the lifting mechanism 11 cooperate to adjust the displacement component 2 to a position coaxial with the sintering cylinder 52. The electric conveying guide rail 124 can be a stepper motor linear guide slide module, which drives the lead screw to rotate by a stepper motor, so that the slide engaged with the lead screw moves horizontally along the extension direction of the lead screw. The displacement component 2 is installed on the slide at the top of the electric conveying guide rail 124. When the displacement component 2 is coaxial with the sintering cylinder 52, the slide on the electric conveying guide rail 124 drives the displacement component 2 to move in the direction of the sintering cylinder 52, so that the displacement component 2 penetrates into the interior of the sintering cylinder 52.

[0058] The specific structure of the displacement component 2 is as follows:

[0059] See also Figure 1 , Figure 3 and Figure 4The displacement assembly 2 includes a support tube 21 installed on the top of the slide seat of the electric conveying guide rail 124 and three fixed plates 22 equidistantly connected to the outer wall of the support tube 21. The side walls of the three fixed plates 22 are provided with through grooves 28. A displacement cylinder 23 is hingedly installed on the side of each fixed plate 22 away from the support tube 21. The piston rod of the displacement cylinder 23 is connected with a slider, and the slider is slidably connected to the inside of the corresponding through groove 28. A crawler drive mechanism 25 is arranged at one end of each fixed plate 22 away from the displacement cylinder 23. A first connecting rod 24 is hinged between the crawler drive mechanism 25 and the corresponding fixed plate 22. A second connecting rod 26 is hinged between the crawler drive mechanism 25 and the corresponding slider. A driving motor 27 for driving is installed on the side wall of each crawler drive mechanism 25. After the electric conveying guide rail 124 extends to the inside of the sintering cylinder 52, first By extending the piston rod of the displacement cylinder 23, the corresponding slider slides inside the corresponding through groove 28, and the slider pushes one end of the second connecting rod 26 to displace synchronously, while the other end of the second connecting rod 26 pushes the track transmission mechanism 25 to displace synchronously. Since the first connecting rod 24 is hinged between the track transmission mechanism 25 and the corresponding fixed plate 22, the displacement of the track transmission mechanism 25 drives the angle of the first connecting rod 24 to change, causing the track transmission mechanism 25 to move away from the support tube 21 while displacing, thereby increasing the distance between the track transmission mechanism 25 and the support tube 21, and multiple track transmission mechanisms 25 are synchronously separated from the support tube 21, and multiple track transmission mechanisms 25 are respectively fitted with the inner wall of the sintering tube 52, so as to position the support tube 21 and keep the support tube 21 and the sintering tube 52 in a coaxial state.

[0060] The crawler track transmission mechanism 25 is composed of track plates and track pins. The track pins connect each track plate to form a crawler chain, and the drive wheel, track roller, road wheel and inducer wheel cooperate to support and engage the track chain respectively. The drive motor 27 is connected to the drive wheel. When the power of the drive motor 27 is transmitted to the drive wheel, the drive wheel pulls the crawler chain clockwise, and the crawler chain drives the track roller, road wheel and inducer wheel to rotate through transmission, thereby achieving the purpose of the crawler track transmission mechanism 25 walking on the inner wall of the sintering cylinder 52.

[0061] See also Figure 1 , Figure 3 and Figure 4 A cleaning assembly 3 is provided at one end of the support tube 21 away from the adjustment assembly 1. The cleaning assembly 3 includes a driving mechanism 33 installed inside the displacement assembly 2 and a side wall cleaning mechanism 31 connected to the output end of the driving mechanism 33. The driving mechanism 33 is used to connect the side wall cleaning mechanism 31 with the support tube 21, and the driving mechanism 33 drives the side wall cleaning mechanism 31 to scrape the slag on the inner wall of the sintering tube 52. The specific structures of the side wall cleaning mechanism 31 and the driving mechanism 33 are as follows:

[0062] See also Figure 4-Figure 6The driving mechanism 33 includes a servo motor 331 installed inside the support tube 21. The output end of the servo motor 331 is connected to the driving tube 332. The driving tube 332 is coaxially arranged with the support tube 21. The side wall cleaning mechanism 31 is connected to the driving tube 332. The servo motor 331 is used to drive the driving tube 332 and the side wall cleaning mechanism 31 to rotate synchronously, so that the side wall cleaning mechanism 31 scrapes the slag on the inner wall of the sintering tube 52.

[0063] See also Figure 4-Figure 6 The servo motor 331 is used to drive the connecting tube 311 to rotate. The outer wall of the connecting tube 311 is sleeved with two connecting flanges 312, and the side wall of each connecting flange 312 is equidistantly connected to a plurality of L-shaped plates 313. The connecting tube 311 is used to drive the two connecting flanges 312 and the corresponding L-shaped plates 313 to rotate synchronously. When the L-shaped plates 313 rotate, the slag on the inner wall of the sintering cylinder 52 is scraped off, and the side wall cleaning mechanism 31 cooperates with the displacement assembly 2, that is, the side wall cleaning mechanism 31 first enters the inner wall of the sintering cylinder 52 for cleaning. As the cleaning continues, the displacement assembly 2 follows and enters the interior of the sintering cylinder 52. This arrangement allows the displacement assembly 2 to fit the inner wall of the sintering cylinder 52 after the slag is scraped off, thereby avoiding slag blocking and affecting the moving route of the displacement assembly 2.

[0064] Embodiment 2: The existing cleaning device can only clean the circumferential surface of the inner wall of the sintering furnace. When the powder adheres to the circular surface of the inner wall of the sintering furnace, the slag accumulated on the circular surface of the inner wall of the sintering furnace cannot be cleaned. Therefore, a bottom surface cleaning mechanism 32 is installed at the end of the side wall cleaning mechanism 31 away from the driving mechanism 33. When the side wall cleaning mechanism 31 goes deep into the deepest position of the circular surface of the inner wall of the sintering furnace for cleaning, the bottom surface cleaning mechanism 32 is used to scrape and clean the slag on the circular surface of the inner wall of the sintering tube 52. The specific structure of the bottom surface cleaning mechanism 32 is as follows:

[0065] See also Figure 5 , Figure 6 and Figure 8In this embodiment, the bottom surface cleaning mechanism 32 includes a cleaning disc 321 connected to an end of the connecting tube 311 away from the support tube 21. A plurality of cleaning plates 322 are connected around the side of the cleaning disc 321 away from the connecting tube 311. The cleaning plates 322 are arranged toward the sintering tube 52. When the connecting tube 311 rotates to drive the side wall cleaning mechanism 31 to rotate, the connecting tube 311 synchronously drives the cleaning disc 321 to rotate, and the cleaning disc 321 drives the plurality of cleaning plates 322 arranged on the side wall to move synchronously. When the side wall cleaning mechanism 31 penetrates into the deepest part of the sintering tube 52, the plurality of cleaning plates 322 fit with the circular surface of the inner wall of the sintering tube 52, and at the same time, the plurality of cleaning plates 322 continuously move, thereby achieving the purpose of scraping off the slag on the circular surface of the inner wall of the sintering tube 52.

[0066] Specifically, the displacement assembly 2 pushes the driving mechanism 33, the side wall cleaning mechanism 31 and the bottom surface cleaning mechanism 32 to move synchronously toward the interior of the sintering cylinder 52. During the movement, the servo motor 331 drives the driving tube 332 and the connecting tube 311 to rotate synchronously, so that the side wall cleaning mechanism 31 and the bottom surface cleaning mechanism 32 synchronously enter the interior of the sintering cylinder 52. First, the side wall cleaning mechanism 31 scrapes the slag on the circumferential surface of the inner wall of the sintering cylinder 52. As the side wall cleaning mechanism 31 and the bottom surface cleaning mechanism 32 continue to go deeper, the displacement assembly 2 enters the interior of the sintering cylinder 52, thereby supporting the support tube 21 and the cleaning assembly 3 as a whole. When the bottom surface cleaning mechanism 32 reaches the circular surface position of the sintering cylinder 52, multiple cleaning plates 322 fit against the circular surface of the inner wall of the sintering cylinder 52, and at the same time, multiple cleaning plates 322 continuously displace, thereby achieving the purpose of scraping the slag on the circular surface of the inner wall of the sintering cylinder 52.

[0067] In addition, there is a gap between the two connecting flanges 312, and the multiple L-shaped plates 313 on each connecting flange 312 are equidistantly arranged, and there is a gap between two adjacent L-shaped plates 313. The scraped slag falls below the inner wall of the sintering tube 52, and the slag slides through the gap between the two L-shaped plates 313, thereby alleviating the situation where the slag is pushed into the interior of the sintering tube 52.

[0068] In addition, multiple cleaning plates 322 extend beyond the outer wall of the cleaning disk 321, and the diameter of the cleaning disk 321 is smaller than the inner diameter of the sintering tube 52. Therefore, the slag scraped off by the cleaning plates 322 can slide through the gap between the cleaning disk 321 and the inner wall of the sintering tube 52, further alleviating the situation where the slag is pushed out of the inside of the sintering tube 52.

[0069] Embodiment 3: After the slag is scraped off, it is accumulated inside the sintering tube 52 due to the influence of gravity. At this time, the staff needs to clean it manually, which greatly increases the workload of the staff. Therefore, a discharge component 4 is installed on the outer wall of the support tube 21. During the scraping process, the slag is continuously discharged by the discharge component 4 to avoid manual cleaning of the slag in the later stage. The specific structure of the discharge component 4 is as follows:

[0070] See also Figure 9-11 The discharge assembly 4 includes a discharge hose 43 disposed inside the support tube 21. A collection box 6 is installed on the top slide of the electric conveying guide rail 124. One end of the discharge hose 43 passes through the interior of the support tube 21 and is connected to the collection box 6. An air pipe is connected to the side wall of the collection box 6. The air pipe is connected to an external suction device. The external suction device can be an air pump, which is not specifically limited here. The air pump sucks out the air inside the collection box 6, so that a negative pressure is formed inside the collection box 6, causing the external air to pass through the discharge hose 43. A gas flow path is formed when entering the collecting box 6, and the discharge hose 43 is located between the support tube 21 and the connecting tube 311, and the discharge hose 43 is directed below the circumferential surface of the inner wall of the sintering tube 52. Therefore, the scraped slag is sucked into the discharge hose 43 through the gas flow path, and finally enters the collecting box 6 for collection. Moreover, the scraping and discharge of the slag are carried out simultaneously, which not only achieves the purpose of timely discharge of the slag without manual collection by the staff, but also alleviates the situation where the slag is pushed into the sintering tube 52.

[0071] Example 4, see Figure 2 , Figure 11-13 The setting of the discharge hose 43 is only applicable to the cleaning of a horizontal sintering furnace, that is, during the slag cleaning process of the horizontal sintering furnace, the slag will fall on the inner wall circular surface of the sintering tube 52 due to the influence of gravity. However, when cleaning a vertical sintering furnace, the slag will directly fall on the inner wall circular surface of the sintering tube 52, and the discharge hose 43 faces the inner wall circular surface of the sintering tube 52, so it is not convenient to discharge the slag on the inner wall circular surface of the sintering tube 52. For this reason, a lifting cylinder 123 is hingedly installed below the top surface of the lifting mechanism 11, and the piston rod of the lifting cylinder 123 is hinged to the bottom of the base plate 121. The lifting cylinder 123 lifts upward, thereby adjusting the base plate 121 to a vertical state, thereby adjusting the displacement assembly 2 and the cleaning assembly 3 to a vertical state. In addition, the height of the displacement assembly 2 and the cleaning assembly 3 is increased by the lifting mechanism 11, so that the cleaning assembly 3 is suitable for cleaning a vertical sintering furnace.

[0072] See also Figure 9-11 The outer wall of the driving tube 332 is connected to a shunt tube 41, the inner diameter of the shunt tube 41 is adapted to the outer diameter of the discharge hose 43, the end of the driving tube 332 away from the displacement assembly 2 passes through the interior of the connecting tube 311 and is connected to a conical suction head 45, the conical suction head 45 is arranged toward the sintering tube 52, when the side wall cleaning mechanism 31 and the bottom cleaning mechanism 32 penetrate into the interior of the sintering tube 52 in a vertical state, the slag falls into the interior of the sintering tube 52 under the influence of gravity, and at this time the conical suction head 45 faces the direction of the slag falling and accumulation.

[0073] See also Figure 10-11In this embodiment, an adjusting mechanism 44 is installed on the outer wall of the support tube 21, and a discharge hose 43 is installed on the adjusting mechanism 44. When the side wall cleaning mechanism 31 and the bottom cleaning mechanism 32 perform slag cleaning on the vertical sintering tube 52, the adjusting mechanism 44 drives the discharge hose 43 to adjust the angle and connects the discharge hose 43 with the diverter pipe 41. At this time, the inlet of the gas flow passage is adjusted to the position of the conical suction head 45, that is, the slag is sucked into the interior of the driving tube 332 through the conical suction head 45, and is discharged into the interior of the discharge hose 43 through the diverter pipe 41, and is finally collected by the collecting box 6.

[0074] See also Figure 8 Each cleaning plate 322 is equidistantly arranged around the axis of the cleaning disk 321 in a clockwise direction. The cleaning plates 322 are arc-shaped and curved in a clockwise direction. When the cleaning plates 322 scrape the slag on the circular surface of the inner wall of the sintering cylinder 52, the slag will move along the curved direction of the cleaning plates 322 and eventually gather toward the position of the conical suction head 45, thereby facilitating the discharge of the slag.

[0075] The specific structure of the regulating mechanism 44 is as follows:

[0076] See also Figure 10-11The adjusting mechanism 44 includes a mounting seat 441 mounted on the outer wall of the support tube 21 and a second adjusting cylinder 444 mounted inside the mounting seat 441. The piston rod of the second adjusting cylinder 444 is arranged toward the support tube 21, and the piston rod of the second adjusting cylinder 444 passes through the mounting seat 441 and is hinged with a mounting plate 443. The first adjusting cylinder 442 is hingedly mounted between the side of the mounting plate 443 away from the second adjusting cylinder 444 and the side wall of the mounting seat 441. The mounting plate 443 is away from the mounting seat 4 An electric adjustment rail 445 is installed on one side of 41, and a slide 446 is slidably connected to the electric adjustment rail 445. The outer wall of the discharge hose 43 is connected to the slide 446. When the discharge hose 43 discharges slag from the horizontal sintering tube 52, the first adjustment cylinder 442 is in a contracted state, and the second adjustment cylinder 444 is in an extended state. At this time, the mounting plate 443 and the electric adjustment rail 445 are between the support tube 21 and the connecting tube 311 and face the circumferential surface of the horizontal sintering tube 52. The slag falling onto the circumferential surface of the sintering cylinder 52 in the horizontal state is directly absorbed and discharged through the discharge hose 43. When the discharge hose 43 discharges the slag from the sintering cylinder 52 in the vertical state, the first regulating cylinder 442 is in an extended state, and the second regulating cylinder 444 is in a contracted state. At this time, the mounting plate 443 and the electric regulating guide rail 445 are between the support pipe 21 and the connecting pipe 311 and toward the direction of the shunt pipe 41. At the same time, the electric regulating guide rail 445 drives the slide 446 and the discharge hose 43 to The direction of the diverter pipe 41 is close, so that the discharge hose 43 can be inserted into the inside of the diverter pipe 41 to complete the connection, and the slag that falls onto the circular surface of the sintering cylinder 52 in the vertical state is absorbed and discharged through the conical suction head 45, the driving pipe 332 and the discharge hose 43. The electric adjustment guide rail 445 can be a stepper motor linear guide slide module, which uses a stepper motor to drive the screw to rotate, so that the slide engaged with the screw moves horizontally along the extension direction of the screw. The slide on this electric adjustment guide rail 445 is a slide table 446.

[0077] See also Figure 10-11 A rubber ring 46 is sleeved and connected to the outer wall of one end of the discharge hose 43 near the regulating mechanism 44, and an electric valve 42 is installed on the outer wall of the shunt pipe 41. When the discharge hose 43 is connected to the shunt pipe 41, the rubber ring 46 is used to seal the gap between the discharge hose 43 and the shunt pipe 41. The electric valve 42 is in a through state, and a gas flow path is formed at this time. If the slag cleaning is completed, the electric valve 42 will close the shunt pipe 41 to prevent the slag from flowing back.
