Vacuum glass bricks, as a new type of energy-saving building material, have gradually attracted the attention of the industry due to their excellent thermal insulation and sound insulation properties.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Reference Figure 1-Figure 7As shown, the present invention provides a continuous vacuum glass edge sealing heating furnace, including a furnace body 1, wherein a feeding zone 11, a preheating zone 12, a heating edge sealing zone 13, a cooling zone 14 and a discharging zone 15 are sequentially arranged inside the furnace body 1 from left to right, and a plurality of furnace doors 2 are arranged inside the furnace body 1, and the feeding zone 11, the preheating zone 12, the heating edge sealing zone 13, the cooling zone 14 and the discharging zone 15 are separated by the furnace doors 2, and the upper and lower ends of the feeding zone 11, the preheating zone 12, the heating edge sealing zone 13, the cooling zone 14 and the discharging zone 15 are fixedly connected to a track 16, and two sets of tracks 16 are slidably provided with a mobile clamping mechanism 4, and the mobile clamping mechanism 4 is used to fix the glass bricks, a heat recovery mechanism 6 is arranged between the preheating zone 12 and the cooling zone 14, and a heat diffusion plate 5 is fixedly connected inside the heating edge sealing zone 13; the mobile clamping mechanism 4 is used to transport the semi-finished glass bricks to the heating edge sealing zone 13 to realize the edge sealing treatment of the semi-finished products. Subsequently, the glass bricks are cooled in the cooling zone 14 by the heat recovery mechanism 6, and the mechanism redistributes the released heat to the preheating zone 12 to provide preheating for the production of the next batch of glass bricks, thereby achieving effective energy conservation.

[0031] In a further embodiment, referring to Figure 2-Figure 3 The movable clamping mechanism 4 includes a lower sliding block 41 and an upper sliding block 45. The side wall of the track 16 below the heat soaking plate 5 is slidably connected with the lower sliding block 41. The upper end of the lower sliding block 41 is fixedly connected to the first telescopic rod 42. The output shaft end of the first telescopic rod 42 is fixedly connected to the fixing seat 43. The upper end surface of the fixing seat 43 is provided with a positioning groove 431. The side wall of the track 16 above the heat soaking plate 5 is slidably connected with the upper sliding block 45. The lower end of the upper sliding block 45 is fixedly connected to the second telescopic rod 46. The output shaft end of the second telescopic rod 46 is fixedly connected to the fixing frame 47. The lower end of the fixing frame 47 is provided with a clamping assembly 48. The front and rear ends of the fixing seat 43 are fixedly connected to the first limit block 44, the first limit block 44 is located in the third limit groove 19 and is slidably connected thereto, and the front and rear ends of the fixing frame 47 are fixedly connected to the second limit block 49, and the second limit block 49 is located in the second limit groove 18 and is slidably connected thereto.

[0032] In this embodiment, the upper sliding block 45 and the lower sliding block 41 are moved simultaneously, so that the semi-finished glass bricks can be moved synchronously. Since the first limit block 44 acts in the third limit groove 19 and the second limit block 49 acts in the second limit groove 18, the two semi-finished glass bricks are brought closer to each other and the edges are tightly pressed together.

[0033] In a further embodiment, referring to Figure 3-Figure 5The clamping assembly 48 includes a clamping head 485 and a control rod 481. The front and rear end surfaces inside the furnace body 1 are sequentially provided with a first limiting groove 17, a second limiting groove 18 and a third limiting groove 19 from top to bottom. A control rod 481 is slidably connected between the two groups of first limiting grooves 17. The front and rear side walls of the control rod 481 are fixedly connected to fixed slides 482. The fixed slides 482 are slidably connected to sliders 483. Four groups of sliders 483 are arranged and are equidistantly distributed around the fixed slides 482. The end of the slider 483 away from the fixed slide 482 is rotatably connected to a connecting rod 484. The end of the connecting rod 484 away from the slider 483 is fixedly connected to the clamping head 485.

[0034] In this embodiment, the control rod 481 can limit its up and down movement under the action of the first limit groove 17. When the control rod 481 moves downward, it will drive the fixed slide 482 and the slider 483 to move downward. The slider 483 slides toward the inside of the fixed slide 482 while descending. In this process, the connecting rod 484 rotates accordingly, thereby driving the clamping head 485 to move, thereby releasing the glass brick; on the contrary, when the control rod 481 moves upward, it will prompt the clamping head 485 to clamp the semi-finished glass brick.

[0035] In a further embodiment, referring to Figure 8 The heat recovery mechanism 6 includes a threaded pipe 61 and a heat conducting plate 64. The threaded pipe 61 is arranged inside the cooling zone 14. Four groups of threaded pipes 61 are arranged and distributed at the four corners of the cooling zone 14. The right end of the threaded pipe 61 is fixedly connected to an air intake pipe 66, and the air intake pipe 66 penetrates to the outside of the furnace body 1. The left ends of the threaded pipes 61 located on the front and rear sides of the furnace body 1 penetrate to the outside of the furnace body 1. A first connecting pipe 62 is fixedly connected between the threaded pipes 61 located on the left end of the outside of the furnace body 1. A heat conducting plate 64 is fixedly connected inside the preheating zone 12. Exhaust pipes 65 are fixedly connected to the front and rear ends of the left side of the heat conducting plate 64. One end of the exhaust pipe 65 away from the heat conducting plate 64 penetrates to the outside of the furnace body 1. Second connecting pipes 63 are fixedly connected to the front and rear ends of the right side of the heat conducting plate 64. One end of the second connecting pipe 63 away from the heat conducting plate 64 is fixedly connected to the side wall of the first connecting pipe 62.

[0036] In this embodiment, the threaded tube 61 is responsible for absorbing the heat of the cooling zone 14 to achieve the purpose of lowering the temperature of the glass bricks; at the same time, the gas is continuously input into the air inlet pipe 66 to drive the air flow and adjust the temperature of the threaded tube 61; in addition, the air in the threaded tube 61 is transported to the heat conduction plate 64 through the first and second connecting tubes 63 to heat it. The heated heat conduction plate 64 preheats the semi-finished glass bricks, effectively reducing the energy consumption in the whole process.

[0037] In a further embodiment, referring to Figure 6-Figure 7The furnace door 2 includes a baffle 22 and a T-block 24. The upper and lower ends of the furnace body 1 are rotatably connected with the rotating shaft 21. The side wall of the rotating shaft 21 is fixedly connected with the baffle 22. The adjacent two end surfaces of the baffle 22 are provided with dovetail grooves 221. The dovetail blocks 23 are equidistantly slidably connected inside the dovetail grooves 221. The end of the dovetail block 23 away from the baffle 22 is fixedly connected with the T-block 24. A spring 25 is fixedly connected between the two groups of dovetail blocks 23. A flip driving mechanism 3 is arranged at the front end of the furnace body 1. The flip driving mechanism 3 is provided with multiple groups. The flip driving mechanism 3 includes a worm 31 and a motor 32. The front end of the furnace body 1 is rotatably connected with the worm 31 through a bearing seat. The threads on both sides of the worm 31 are in opposite directions. A worm wheel 33 is fixedly connected to the front end of the rotating shaft 21. The worm 31 and the worm wheel 33 are meshed with each other. The upper end of the furnace body 1 is fixedly connected with a motor 32, and the output shaft end of the motor 32 is fixedly connected to the upper end of the worm 31.

[0038] In this embodiment, after the motor 32 is started, its power is transmitted through the worm 31, causing the worm wheel 33 to rotate. The rotation of the worm wheel 33 further drives the rotating shaft 21. The rotation of the rotating shaft 21 causes the baffle 22 to rotate accordingly. The rotation of the baffle 22 drives the T-block 24 to move. When the baffle 22 rotates to a horizontal position, the T-block 24 is aligned with the track 16. During the movement of the T-block 24, the deformation restoring force of the spring 25 pushes the T-block 24 to move, ensuring that multiple T-blocks 24 are evenly distributed on the baffle 22, providing convenience for the smooth passage of the upper sliding block 45 or the lower sliding block 41; when the worm 31 rotates in the opposite direction, the baffle 22 rotates accordingly, so that the upper and lower groups of baffles 22 contact each other, achieving a sealing effect.

[0039] In a further embodiment, referring to Figure 1-Figure 2 A negative pressure machine 7 is arranged at the upper end of the furnace body 1. Two groups of negative pressure machines 7 are arranged. The negative pressure machines 7 are respectively located above the cooling zone 14 and the preheating zone 12.

[0040] In this embodiment, when the semi-finished product is moved to the preheating zone 12, the flipping drive mechanism 3 will close the furnace door 2 connecting the feeding zone 11 and the preheating zone 12, and activate the negative pressure machine 7 of the preheating zone 12 to create a vacuum environment, so as to facilitate the subsequent processing of the glass brick semi-finished product; similarly, when the processed glass bricks are moved from the cooling zone 14 to the discharge zone 15, the flipping drive mechanism 3 will again close the furnace door 2 between the cooling zone 14 and the discharge zone 15, and start the negative pressure machine 7 of the cooling zone 14 to ensure that a vacuum state is formed inside the cooling zone 14.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
