DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0040] When using an annealing furnace to heat-treat metal, the height of the liquid surface scraping rod 6 can be controlled. Then, using a single-chip microcomputer controller, the stepping motor 3 is turned on, which drives the drive shaft 4 and the driving rod 5 to rotate, so that the liquid surface scraping rod 6 can rotate slowly and continuously, effectively avoiding irregular surfaces such as wrinkles and waves that may occur during the annealing process of the metal, making the metal surface smoother.

[0041] Please refer to Figure 3-6 As shown, the self-cleaning component 8 includes a toothed ring 9 fixedly connected to the inner wall of the annealing furnace body 1. A first rotating rod 10 is provided at the top of the scraper 7. An upper driving wheel 11 and a lower first bevel gear 12 are fixedly sleeved on the outer wall of the first rotating rod 10 respectively. A transmission belt 13 is arranged inside the scraper 7. A pair of belt pulleys 14 are drivingly connected to the inner wall of the transmission belt 13. A supporting wheel is also drivingly connected to the inner wall of the transmission belt 13. A supporting rod is rotatably connected to the inner wall of the supporting wheel, and the supporting rod is fixedly connected to the inside of the scraper 7. A second rotating rod 15 is fixedly connected to the inner wall of the belt pulley 14. A second bevel gear 16 is fixedly sleeved on the outer wall of the second rotating rod 15. The first bevel gear 12 and the second bevel gear 16 are meshed with each other, and the driving wheel 11 is meshed with the toothed ring 9; a plurality of magnetic attraction pieces 17 are fixedly connected to the outer end of the transmission belt 13. A cleaning plate 18 is arranged at the outer end of the liquid surface scraping rod 6. The cleaning plate 18 is slidably attached to the outer end of the scraper 7. A magnetic attraction area corresponding to the magnetic attraction pieces 17 is arranged inside the cleaning plate 18.

[0042] Please refer to Figure 6 As shown, a first support plate 20 is rotatably connected to the bottom of the liquid surface scraping rod 6. The top of the first support plate 20 is fixedly connected to the cleaning plate 18. The cleaning plate 18 is in a U-shaped structure. A groove is formed in the cleaning plate 18. The magnetic attraction area is a magnetic sheet located at the groove, and the magnetic sheet and the magnetic attraction pieces 17 attract each other.

[0043] The driving rod 5 is a square rod. A sliding sleeve 19 is arranged at the outer end of the driving rod 5. A high-temperature resistant solenoid valve is arranged between the driving rod 5 and the sliding sleeve 19. It is a solenoid valve that can work normally in a high-temperature environment. It usually adopts special materials and structures to meet the requirements of the high-temperature environment. The outer wall of the sliding sleeve 19 is fixedly connected to the liquid surface scraping rod 6. During use, the solenoid valve can be turned on, and the solenoid valve adsorbs the sliding sleeve 19, so that it can be suspended at a certain height.

[0044] A pair of second support plates 21 are fixedly connected to the top of the scraper 7. A support rod 22 is fixedly connected to the outer end of the second support plate 21. The support rod 22 and the first rotating rod 10 are rotatably connected through a bearing, so that the friction force received by the first rotating rod 10 is very small, facilitating its easy rotation. The two ends of the second rotating rod 15 are respectively rotatably connected to the side walls of a pair of second support plates 21.

[0045] When the annealing furnace is not in use, the insulation cover 2 can be opened, and the self-cleaning component 8 can be placed inside the annealing furnace body 1. At this time, the solenoid valve is disconnected, and the scraper 7 is inserted into the inner side of the cleaning plate 18, and the driving wheel 11 is aligned with the gear ring 9. At this time, the magnetic suction area is just adsorbed with the magnetic suction sheet 17, and then the insulation cover 2 is put on. At this time, the driving shaft 4 is just inserted into the top of the active rod 5, and the stepper motor 3 is turned on. The stepper motor 3 still drives the liquid level scraper 6 to rotate, and the liquid level scraper 6 drives the scraper 7 to rotate through the cleaning plate 18 to clean the inner wall of the annealing furnace body 1 and remove metal scale. The metal scale is scratched and falls to the bottom of the annealing furnace body 1. During the rotation of the scraper 7, the driving wheel 11 meshes and rotates in the gear ring 9, and drives the first rotating rod 10 to rotate. The first rotating rod 10 meshes with the first bevel gear 12 and the second bevel gear 16 to transmit power to the pulley 14. The pulley 14 drives the transmission belt 13 to move, so that the transmission belt 13 drives the cleaning plate 18 to move up and down, and the scraper 7 itself is cleaned, and the dirt adhering to the scraper 7 is effectively removed and falls to the bottom of the annealing furnace body 1, which is convenient for subsequent unified recovery and cleaning.

[0046] See also Figure 7-8 In an embodiment further provided by the present invention, the cleaning unit also includes a scraper cleaning component 23; the scraper cleaning component 23 includes an arc-shaped scraper blade 24 arranged on the outside of the liquid level scraper 6, one side end of the scraper 7 is fixedly connected to a gear bar 25, and the other side end of the scraper 7 is provided with a guide groove, and the inside of the guide groove is slidably connected to a support frame 26, and the side end of the support frame 26 is rotatably connected to a third rotating rod 27 and a driven rod 28, the outer end of the third rotating rod 27 is fixedly sleeved with a transmission gear 29 and a third bevel gear 30, and the outer wall of the driven rod 28 is fixedly sleeved with a fourth bevel gear 31, the third bevel gear 30 is meshedly connected with the fourth bevel gear 31, and the side end of the liquid level scraper 6 is transmission-connected to the driven rod 28.

[0047] When the liquid level scraper 6 moves up and down with the cleaning plate 18, the transmission gear 29 meshes and rolls on the outside of the gear bar 25, driving the third rotating rod 27 to rotate, and the third rotating rod 27 in turn drives the third bevel gear 30 to rotate. The third bevel gear 30 meshes with the fourth bevel gear 31 to transmit power to the driven rod 28, so that the driven rod 28 rotates with the liquid level scraper 6. Since the bottom end of the arc-shaped scraper blade 24 is in close contact with the outer wall of the liquid level scraper 6, the liquid level scraper 6 can also be cleaned during the process of the cleaning plate 18 cleaning the scraper 7, thereby saving the labor of cleaning the liquid level scraper 6 separately in the future, saving trouble and effort.

[0048] See also Figure 9-10In an embodiment further provided by the present invention, the cleaning unit also includes a trigger component 32 arranged on the scraper rod cleaning component 23; the trigger component 32 includes an active disk 33 fixedly mounted on the outer wall of the driven rod 28, and the side end of the active disk 33 is fixedly connected to a plurality of elastic rods 34, the side end of the liquid level scraper rod 6 is rotatably connected to an air storage box 35, and the inner wall of the air storage box 35 is rotatably connected to a rotating plate 36, and a plurality of driving holes 37 corresponding to the elastic rods 34 are opened on the rotating plate 36, and the side end of the rotating plate 36 is fixedly connected to a driven shaft 38, and one end of the driven shaft 38 is fixedly connected to one end of the liquid level scraper rod 6.

[0049] When the scraper 7 is inserted into the inner side of the cleaning plate 18, the elastic rod 34 is located at the top of the air storage box 35, pressing the active disk 33 so that the elastic rod 34 can be inserted into the inside of the driving hole 37. At this time, the driving wheel 11 is aligned with the gear ring 9, and the magnetic area is just adsorbed with the magnetic sheet 17; if the elastic rod 34 is not inserted into the inside of the driving hole 37, it should be in a compressed state. At this time, the air storage box 35 is pushed to make the transmission gear 29 start to rotate, indirectly driving multiple elastic rods 34 to rotate, and eventually they will enter the inside of the driving hole 37. Then, under the rotation of the driving gear, the driving force can be transmitted to the rotating plate 36 and the driven shaft 38 through the active disk 33, and finally the purpose of rotating the liquid level scraper 6 is achieved.

[0050] See also Figure 11-12 In a solution further provided by the present invention, the outer end of the first support plate 20 is rotatably connected to a trigger shaft 39, the outer wall of the trigger shaft 39 is fixedly connected to the inner wall of the arc-shaped scraper 24, the inner wall of the air storage box 35 is slidably connected to a sealing plate 40, the outer end of the air storage box 35 is fixedly connected to an elastic bag 41, one end of the trigger shaft 39 movably passes through the other side of the first support plate 20, the outer end of the trigger shaft 39 is fixedly connected to a baffle 42, and the top end of the elastic bag 41 is in contact with the baffle 42.

[0051] In the initial state, the arc scraper 24 is separated from the liquid level scraper rod 6, making it difficult for the arc scraper 24 to come into contact with metal. When the elastic rod 34 is inserted into the driving hole 37, driven by the elastic force, the sealing plate 40 will be pushed to start moving, and the gas inside the air storage box 35 will be transported to the elastic bag 41, causing the elastic bag 41 to start extending. Finally, the extension of the elastic bag 41 will push the baffle 42 to rotate, causing the arc scraper 24 to start rotating, forcing its bottom end to be close to the outer end of the liquid level scraper rod 6, and by driving the liquid level scraper rod 6 to rotate, it cleans itself.

[0052] The present invention, through the cooperation between the elastic rod 34 and the driving hole 37, can not only convert the driving force of the up and down movement of the cleaning plate 18 into the power for the rotation of the active disk 33, so that the liquid level scraper rod 6 can indirectly obtain the driving force from the up and down movement of the cleaning plate 18, but also can bring about the effect of extending the elastic bag 41 through this process, and then rotate with the arc scraper 24, so that when the liquid level rotating rod is ready to rotate, the arc scraper 24 can just fit tightly against its outer wall, thereby achieving the purpose of cleaning the liquid level scraper rod 6. The structural design is ingenious, and the driving force brought by the stepping motor 3 is divided into multiple powers, and each part of the power is reasonably used.

[0053] In a solution further provided by the present invention, the top of the elastic rod 34 is a smooth spherical structure, the elastic rod 34 itself is a telescopic structure, and an elastic member is arranged inside, and the bottom of the arc scraper 24 is sharp and made of hard metal material.

[0054] The elastic member is a compression spring, and the elastic rod 34 can be a telescopic rod structure with a compression spring arranged inside. When it does not enter the driving hole 37, it temporarily enters a compressed state. After rotating a certain angle, it is inserted into the driving hole 37 by elastic force.

[0055] See also Figure 1 In a solution further provided by the present invention, a pair of friction wheels 43 are fixedly connected to the outer end of the annealing furnace body 1, and the inner wall of the friction wheel 43 is rotatably connected to a support seat 44 through a movable bearing.

[0056] To facilitate the placement of the scraper 7, the annealing furnace body 1 can be tilted. After the annealing furnace body 1 is tilted 90 degrees, the annealing furnace body 1 is in a horizontal state. Then the insulation cover 2 is opened. Under the action of gravity, the liquid level scraper rod 6 is located at the bottom. At this time, the scraper 7 can be easily inserted horizontally into the inner side of the cleaning plate 18, and then the solenoid valve is disconnected. If the liquid level scraper rod 6 is close to the inner bottom of the annealing furnace body 1 at this time, the annealing furnace body 1 can be further tilted, and the solenoid valve can be disconnected so that it can slide to the top of the annealing furnace body 1, and then the solenoid valve is opened to temporarily fix the position of the liquid level scraper rod 6. When the scraper 7 is just inserted into the inner side of the cleaning plate 18 and the elastic rod 34 also enters the driving hole 37, the solenoid valve is disconnected.

[0057] In the solution further provided by the present invention, a reduction motor 45 is provided below the friction wheel 43, and the output end of the reduction motor 45 is fixedly connected to the motor shaft 46. The outer wall friction sleeve of the friction wheel 43 is provided with a friction belt 47, and the inner wall of the friction belt 47 is transmission-connected to the motor sleeve 48, and the inner wall of the motor sleeve 48 is fixedly connected to the outer wall of the motor shaft 46.

[0058] In order to save labor, a reduction motor 45 can be provided. When the annealing furnace body 1 needs to be tilted, the reduction motor 45 can be turned on to slowly rotate the annealing furnace body 1 through the friction belt 47. When it needs to be reset later, the reduction motor 45 can be driven in the opposite direction.

[0059] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
