Description

Technical Field

[0001] The present invention relates to the technical field of enamel firing, and particularly to an enamel firing furnace. Background Art

[0002] An enamel firing furnace generally includes parts such as a furnace body, a furnace door, and a furnace top. The furnace body is composed of multiple furnace walls. The furnace walls and the furnace door are made of reinforcing ribs and high-temperature lightweight refractory materials to improve their high-temperature resistance and structural strength. A reinforcing frame is also provided on the outer side of the furnace wall to enhance the stability of the overall structure. The furnace top is generally designed as a flat top for convenient installation and maintenance.

[0003] For example, the publication number is CN114150315A. This invention discloses a new type of enamel firing furnace, belonging to the technical field of manufacturing chemical equipment. It includes a furnace body. Support columns are arranged on the left and right sides outside the furnace body. The tops of the two support columns are fixedly installed with a top plate. A moving mechanism is installed inside the top plate. The bottom end of the moving mechanism is drivingly connected with a hoisting mechanism. By setting the hoisting mechanism, the furnace cover, the mounting rack and the enamel placed on the mounting rack below can be hoisted upward. When the bottom end of the mounting rack is higher than the upper surface of the furnace body, then start the moving mechanism to move the mounting rack and the processed enamel to the right end of the furnace body, and then lower the mounting rack and the enamel through the hoisting mechanism. The staff can then remove the processed enamel and place the enamel to be processed for subsequent processing. The design of this structure solves the problem of time-consuming and laborious traditional loading and unloading, improves work efficiency, and at the same time ensures the safety during material taking.

[0004] In the above-mentioned prior art, the mounting rack is lifted to another position through a hoisting component. The staff places the enamel into the mounting rack, and then the mounting rack is lifted into the furnace body again through the hoisting mechanism and heated by a heating device. However, due to the different shapes and structures of the enamel, the surface heating degrees are also different. Therefore, it takes a longer time to reach the required temperature distribution and melting effect, which will prolong the time of the entire production process, thereby reducing production efficiency. Secondly, the internal space of the furnace body is limited, and the surface temperature of the heated enamel is relatively high and it is not easy to take out from the furnace. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the prior art that due to the different shapes and structures of the enamel, the surface heating degrees are also different.

The connecting rotating block is snap-connected to the connecting rotating column. A fourth gear is fixedly connected to the bottom end of the lifting rod located at the bottom of the connecting rotating block. The fourth gear meshes with one end of the third gear.

[0011] As a preferred embodiment, the conversion assembly includes a support shell fixed to the side of the placing table away from the first rotating rod at the bottom end. A second limiting chute is opened in the middle of the side of the support shell close to the first motor. A first support ring is fixedly connected to the side of the support shell away from the first rotating rod inside. A fixed pull rod is slidably connected to the middle of the first support ring.

The second limiting chute can guide the first connecting head. One end of the fixed pull rod is set to deflect, which can help the first connecting head follow the guidance of the second limiting chute.

[0012] As a preferred embodiment, a clamping block is fixedly connected to the end of the fixed pull rod away from the first motor. A convex rod is clamped inside the clamping block. A movable pull rod is fixedly connected to the side of the convex rod away from the fixed pull rod. A pull ring is fixedly connected to the end of the movable pull rod away from the clamping block. The pull ring is located outside the furnace body. One end of the movable pull rod located inside the pulling groove is slidably connected to a second support ring. The second support ring is fixedly connected to the furnace body. Pushing or pulling the pull ring, the pull ring drives the clamping block through the convex rod. The clamping block drives the fixed pull rod to move. The fixed pull rod drives the first connecting head to move. And the first connecting head slides along the track of the second limiting chute. When the placing table moves, it drives the clamping block to rotate, and the convex rod can be separated from both sides of the clamping block, thus avoiding blocking the rotation of the clamping block by the convex rod.

[0013] As a preferred embodiment, a first connector is rotatably connected to one end of the fixed pull rod away from the pull ring. Both sides of the first connector are slidably connected to the second limiting chute. A rocker is slidably connected to the bottom end of the first connector. Lifting chutes are formed on both sides of the top end of the rocker and are slidably connected to the rocker. One end of the rocker close to the pull ring is rotatably connected to a deflection shaft, and the deflection shaft is fixedly connected to the support shell. When the first connector slides, it drives one side of the rocker away from the deflection shaft to tilt upward through the rocker. The rocker drives the second connector and the fixed ring to be pulled upward, and stretches the spring. The fixed ring drives the lifting rod to rise, and the lifting rod drives the connecting rotating block to insert into the inside of the connecting rotating column, so as to drive the placement table to rotate after the first motor is started.

The fixed ring is fixed at the bottom end of the lifting rod located at the fourth gear. Pull the pull ring. The pull ring drives the fixed pull rod to move leftward through the clamping connection between the movable pull rod and the clamping block. The fixed pull rod drives the first connector to slide downward along the track of the second limiting chute. As the side of the first connector away from the spring moves downward, the spring pulls the rocker to deflect downward, thereby driving the fixed ring to move downward. The fixed ring drives the lifting rod to move downward, so that the fourth gear meshes with the third gear, thereby realizing the extension of the placement board.

[0015] As a preferred embodiment, the air circulation assembly includes a worm, which is rotatably connected to the inside of the furnace body near one side of the installation groove.

The first motor drives the driving rotating shaft to rotate, the driving rotating shaft drives the first runner to rotate, the first runner drives the second runner to rotate through the belt, the second runner drives the worm to rotate, the worm drives the worm gear to rotate, the worm gear drives the support rotating rod to rotate, the worm gear drives the fan to rotate, and the fan can blow the hot air in the furnace body to prevent the hot air from accumulating at a certain position. After the gas is blown, part of it enters the ventilation groove and then is ejected through the installation groove, realizing the circulating flow of the gas, which helps the glass lining to be heated evenly. Since the size of the belt is larger than that of the second runner, the rotation speed of the fan is greater than the rotation speed of the belt.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, the staff places the glass-lined enamel on the top of the placement plate, starts the first motor to drive the driving rotating shaft to rotate, the driving rotating shaft drives the lifting rod to rotate, the lifting rod drives the connecting rotating column to rotate, the connecting rotating column drives the placement table to rotate, and the placement table drives the placement plate to rotate, so that the glass-lined enamel rotates slowly, ensuring that all parts of it are evenly heated. Moreover, rotation can also promote heat convection inside the metal object and accelerate the heat transfer speed, further improving the heating efficiency. When the heating is over, the lifting rod moves downward to drive the fourth gear to engage with the third gear, causing the second gear to rotate. The second gear drives the first gear to rotate, and the first gear drives the threaded rod to rotate. The threaded rod drives the placement plate to extend through the first limiting chute, facilitating the removal of the glass-lined enamel.

[0018] 2. In the present invention, when it is necessary to drive the placement table to rotate, push the pull ring. The pull ring pushes the block through the convex rod, and the block pushes the fixed pull rod to move. The fixed pull rod drives the first connecting head to move to the right. The first connecting head slides upward along the track of the second limiting chute. And the first connecting head drives the side of the rocker arm away from the deflection shaft to tilt upward through the rocker arm. The rocker arm drives the second connecting head and the fixed ring to be pulled upward, and stretches the spring. The fixed ring drives the lifting rod to rise. The lifting rod drives the connecting rotating block to insert into the inside of the connecting rotating column. Thus, after the first motor is started, it drives the placement table to rotate. When it is necessary for the placement plate to extend, the pull ring can be pulled. The pull ring drives the fixed pull rod to move to the left through the clamping connection of the movable pull rod and the block. The fixed pull rod drives the first connecting head to slide downward along the track of the second limiting chute. As the first connecting head moves away from the spring side and moves downward, the spring pulls the rocker arm to deflect downward, thereby driving the fixed ring to move downward. The fixed ring drives the lifting rod to move downward, causing the fourth gear to engage with the third gear, thus realizing the extension of the placement plate.

[0019] 3. In the present invention, the first motor drives the driving rotating shaft to rotate, the driving rotating shaft drives the first runner to rotate, the first runner drives the second runner to rotate through the belt, the second runner drives the worm to rotate, the worm drives the worm gear to rotate, the worm gear drives the supporting rotating rod to rotate, the worm gear drives the fan to rotate. The fan can blow the hot air in the furnace body to avoid the accumulation of hot air at a certain position. And after the gas is blown, part of it enters the ventilation groove and then sprays out through the installation groove, realizing the circulating flow of the gas, which helps the glass-lined enamel to be evenly heated. Since the belt size is larger than the second runner, the rotation speed of the fan is greater than the rotation speed of the belt. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In this embodiment, the staff places the glass-lined enamel on the top of the placing plate 22, starts the first motor 31 to drive the driving rotating shaft 32 to rotate, the driving rotating shaft 32 drives the lifting rod 34 to rotate, the lifting rod 34 drives the connecting rotating column 25 to rotate, the connecting rotating column 25 drives the placing table 21 to rotate, and the placing table 21 drives the placing plate 22 to rotate, so that the glass-lined enamel rotates slowly, ensuring that all parts of it can be heated evenly. Moreover, rotation can also promote heat convection inside the metal object and accelerate the heat transfer speed, further improving the heating efficiency. When the heating is over, the lifting rod 34 moves downward to drive the fourth gear 36 to engage with the third gear 211, causing the second gear 29 to rotate. The second gear 29 drives the first gear 27 to rotate, so that the first gear 27 drives the threaded rod 26 to rotate. The threaded rod 26 drives the placing plate 22 to extend out through the first limiting chute 23, facilitating the removal of the glass-lined enamel.

[0035] As Figure 1 - Figure 9 shown, the conversion assembly includes a support shell 51. The support shell 51 is fixed to one side of the bottom end of the placing table 21 away from the first rotating rod 28. A second limiting chute 5111 is provided in the middle of the side of the support shell 51 close to the first motor 31. A first support ring 53 is fixedly connected to the side of the inside of the support shell 51 away from the first rotating rod 28. A fixed pull rod 52 is slidably connected to the middle of the first support ring 53. A part of the end of the fixed pull rod 52 close to the first motor 31 can deflect. One end of the fixed pull rod 52 away from the first motor 31 is fixedly connected to a clamping block 54. A convex rod 551 is clamped inside the clamping block 54. One side of the convex rod 551 away from the fixed pull rod 52 is fixedly connected to a movable pull rod 55. One end of the movable pull rod 55 away from the clamping block 54 is fixedly connected to a pull ring 57. The pull ring 57 is located outside the furnace body 1. One end of the movable pull rod 55 located inside the pull groove 12 is slidably connected to a second support ring 56. The second support ring 56 is fixedly connected to the furnace body 1. One end of the fixed pull rod 52 away from the pull ring 57 is rotatably connected to a first connection head 58. Both sides of the first connection head 58 are slidably connected to the second limiting chute 5111. The bottom end of the first connection head 58 is slidably connected to a lever 59. Lifting chutes 510 are provided on both sides of the top end of the lever 59. The lifting chutes 510 are slidably connected to the lever 59. One end of the lever 59 close to the pull ring 57 is rotatably connected to a deflection shaft 511. The deflection shaft 511 is fixedly connected to the support shell 51. One side of the bottom end of the lever 59 away from the deflection shaft 511 is fixedly connected to a spring 514. The bottom end of the spring 514 is fixedly connected to the support shell 51. One end of the lever 59 away from the deflection shaft 511 is rotatably connected to a second connection head 512. One side of the second connection head 512 away from the lever 59 is fixedly connected to a fixed ring 513. The fixed ring 513 is fixed to the bottom end of the lifting rod 34 where the fourth gear 36 is located.

[0036] In this embodiment, when it is necessary to drive the placement table 21 to rotate, the pull ring 57 is pushed. The pull ring 57 pushes the clamping block 54 through the convex rod 551. The clamping block 54 pushes the fixed pull rod 52 to move. The fixed pull rod 52 drives the first connector 58 to move to the right. And the first connector 58 slides upward along the track of the second limit chute 5111. And the first connector 58 slides and drives the lever 59 to tilt upward on the side away from the deflection shaft 511. The lever 59 drives the second connector 512 and the fixed ring 513 to be pulled upward, and stretches the spring 514. The fixed ring 513 drives the lifting rod 34 to rise. The lifting rod 34 drives the connecting rotating block 35 to insert into the inside of the connecting rotating column 25. Thus, after the first motor 31 is started, it drives the placement table 21 to rotate. When it is necessary to extend the placement plate 22, the pull ring 57 can be pulled. The pull ring 57 drives the fixed pull rod 52 to move to the left through the clamping connection between the movable pull rod 55 and the clamping block 54. The fixed pull rod 52 drives the first connector 58 to slide downward along the track of the second limit chute 5111. As the first connector 58 moves away from the spring 514 and moves downward, the spring 514 pulls the lever 59 to deflect downward. Thus, it drives the fixed ring 513 to move downward. The fixed ring 513 drives the lifting rod 34 to move downward, so that the fourth gear 36 meshes with the third gear 211. Thus, the placement plate 22 is extended.

[0037] As Figure 1 - Figure 9 As shown, the driving assembly includes a first motor 31. The first motor 31 is fixed at the bottom end inside the furnace body 1. The top end of the first motor 31 is drivingly connected with a driving rotating shaft 32. The middle part of the driving rotating shaft 32 is fixedly connected with a first runner 33. The middle part of the first runner 33 is drivingly connected with a belt 331. The top end of the driving rotating shaft 32 is slidably connected with a lifting rod 34. The top end of the lifting rod 34 is fixedly connected with a connecting rotating block 35. The connecting rotating block 35 is clamped with the connecting rotating column 25. The bottom end of the lifting rod 34 at the top end of the connecting rotating block 35 is fixedly connected with a fourth gear 36. The fourth gear 36 meshes with one end of the third gear 211. The air circulation assembly includes a worm 41. The worm 41 is rotatably connected inside the furnace body 1 near one side of the installation groove 15. The bottom end of the worm 41 is fixedly connected with a second runner 42. The second runner 42 is drivingly connected with the belt 331. The top end of the worm 41 meshes with a worm gear 43. The middle part of the worm gear 43 is fixedly connected with a support rotating rod 44. The support rotating rod 44 is rotatably connected with the furnace body 1. One end of the support rotating rod 44 close to the door body 11 is fixedly connected with a fan 45.

[0038] In this embodiment, the first motor 31 drives the driving rotating shaft 32 to rotate, the driving rotating shaft 32 drives the first runner 33 to rotate, the first runner 33 drives the second runner 42 to rotate through the belt 331, the second runner 42 drives the worm 41 to rotate, the worm 41 drives the worm wheel 43 to rotate, the worm wheel 43 drives the supporting rotating rod 44 to rotate, the worm wheel 43 drives the fan 45 to rotate, and the fan 45 can disperse the hot air in the furnace body 1 to prevent the hot air from accumulating at a certain position. After being blown, part of the gas enters the ventilation groove 14 and then is ejected through the installation groove 15, realizing the circulating flow of the gas, which helps the glass lining to be heated evenly. Since the size of the belt 331 is larger than that of the second runner 42, the rotation speed of the fan 45 is greater than the rotation speed of the belt 331.

[0039] Working principle: First, the staff opens the door body 11, places the glass-lined enamel at the center of the placement plate 22 and then closes the door body 11. The heating tube 13 is started, and the heating tube 13 generates high temperature to heat the glass-lined enamel. When the placement table 21 needs to rotate, the pull ring 57 is pushed. The pull ring 57 pushes the clamping block 54 through the convex rod 551. The clamping block 54 pushes the fixed pull rod 52 to move. The fixed pull rod 52 drives the first connector 58 to move to the right. The first connector 58 slides upward along the track of the second limit chute 5111. And the first connector 58 slides to drive the rocker 59 through the rocker 59 to lift the side of the rocker 59 away from the deflection shaft 511 upward. The rocker 59 drives the second connector 512 and the fixed ring 513 to be pulled upward, and stretches the spring 514. The fixed ring 513 drives the lifting rod 34 to rise. The lifting rod 34 drives the connecting rotating block 35 to insert into the inside of the connecting rotating column 25. Thus, after the first motor 31 is started, it drives the placement table 21 to rotate. The placement table 21 drives the placement plate 22 to rotate. The placement plate 22 drives the glass-lined enamel to rotate, making the glass-lined enamel rotate slowly, so as to ensure that all parts of it can be evenly heated. And rotation can also promote the heat convection inside the metal object and accelerate the heat transfer speed, further improving the heating efficiency. When driving the rotating shaft 32 to rotate, it can drive the first runner 33 to rotate. The first runner 33 drives the second runner 42 to rotate through the belt 331. The second runner 42 drives the worm 41 to rotate. The worm 41 drives the worm gear 43 to rotate. The worm gear 43 drives the support rotating rod 44 to rotate. The worm gear 43 drives the fan 45 to rotate. The fan 45 can blow the hot air in the furnace body 1 to avoid the accumulation of hot air in a certain position. And after the gas is blown, part of it enters the ventilation groove 14 and then is ejected through the installation groove 15 to realize the circulating flow of the gas, which helps the glass-lined enamel to be evenly heated. Since the size of the belt 331 is larger than that of the second runner 42, the rotation speed of the fan 45 is greater than the rotation speed of the belt 331. After the heating is completed, the first motor 31 stops rotating. The placement plate 22 is aligned with the door body 11. The door body 11 is opened. The pull ring 57 is pulled. The pull ring 57 drives the fixed pull rod 52 to move to the left through the clamping connection between the movable pull rod 55 and the clamping block 54. The fixed pull rod 52 drives the first connector 58 to slide downward along the track of the second limit chute 5111. As the first connector 58 moves away from the side of the spring 514 and moves downward, the spring 514 pulls the rocker 59 to deflect downward, thus driving the fixed ring 513 to move downward. The fixed ring 513 drives the lifting rod 34 to move downward, making the fourth gear 36 engage with the third gear 211, making the second gear 29 rotate. The second gear 29 drives the first gear 27 to rotate, making the first gear 27 drive the threaded rod 26 to rotate. The threaded rod 26 drives the placement plate 22 to extend through the first limit chute 23. At this time, the staff can remove the glass-lined enamel. Then the first motor 31 rotates in reverse, and the placement plate 22 retracts. Then the operation is repeated.
