[0002] In the glass manufacturing process, kiln baking is the process of gradually raising the kiln from room temperature to the normal working temperature. It is a process of performing a series of temperature control and expansion management for the transition of the kiln from cold state to hot state. Overflow method substrate glass kilns generally use natural gas hot air kiln baking technology. Natural gas is fully burned in the hot air gun and mixed with a large amount of excess air. The air is heated to a certain temperature and then evenly sprayed to various parts of the kiln. The kiln maintains a slight positive pressure, and the furnace body can be evenly thermally expanded under the full reflux of hot air.

[0003] In the prior art, the support of the furnace silo of overflow method substrate glass adopts a light steel frame support platform structure, and the installation method of the kiln hot air gun is: relying on the steel structure of the feeding platform, using a chain (hand winch) binding and hanging method.

[0004] The latest high-generation overflow substrate glass plant has been designed with full consideration of the compatibility of future line upgrades, and has undergone disruptive structural changes and optimizations compared to previous low-generation production line plants. The building structure and material bunker structure in the front area of ​​the kiln have eliminated the traditional steel platform frame structure of the front bunker. This makes it very difficult to implement the original chain hanging method of the kiln hot air gun in the front of the new high-generation plant structure.

[0005] Therefore, how to design a support and installation method for the kiln hot air gun so that it perfectly matches the new design of the current high-generation overflow method substrate glass plant has become a technical problem that urgently needs to be solved in this industry.

[0028] As attached Figure 1As shown in the figure, the trolley structure of the baking hot air gun for the substrate glass furnace of the present utility model includes a vehicle frame 8, and a caster 17 with a rotating function is installed at the bottom of the vehicle frame 8; expansion legs 18 are symmetrically arranged at the bottom of the vehicle frame 8; a front support 12 is arranged at the upper end of the vehicle frame 8, and a gun barrel snap ring 11 is coupled to the front support 12; a vehicle-mounted jack 9 is rigidly connected to the upper end of the vehicle frame 8, and a rear support 10 is connected to the telescopic end of the vehicle-mounted jack 9; a lifting lug 16 is also arranged above the vehicle frame 8, and a fastening assembly formed by a turnbuckle 13 and a steel wire rope 14 is used to connect the lifting lug 16 and the gun barrel snap ring 11, and a wire rope clamp 15 is used for fixing the steel wire rope to other structures.

[0029] In the embodiment of this patent, the vehicle frame 8 is welded by stainless steel rectangular tubes, the material of the rectangular tubes is SUS304, and the specification is preferably 50*50*2.5mm. Four casters 17 are installed at the four corners of the bottom of the vehicle frame 8, and the connection method between the casters and the vehicle frame is welding and bolt connection; the caster 17 is a universal caster with a foot brake, and the outer ring of the caster 17 is an insulating rubber ring to ensure the ground insulation of the trolley. The expansion leg 18 is bolted to the bottom of the vehicle frame 8, and its function is to enhance the static stability of the vehicle body and prevent the trolley from tipping over due to accidental collision during the baking process. The vehicle-mounted jack 9 and the rear support 10 are used to support the rear end of the hot air gun 2, and the vehicle-mounted jack 9 can quickly adjust the height of the rear end of the hot air gun, so as to realize the adjustment of the gun body inclination angle. They are connected to each other and to the vehicle frame 8 by electric welding. The front support 12 is used to support the front end of the hot air gun 2. By adjusting the height of the front support 12 with the first bolt 20, the height of the muzzle of the hot air gun can be finely adjusted to match the height of the feeding port 5. The snap ring 11 is installed at the front end of the gun body, and the gun barrel can be tightened by adjusting the screw. It, together with the turnbuckle 13, the steel wire rope 14, the wire rope clamp 15 and the lifting lug 16, jointly forms a tensioning and fixing structure to prevent the gun body of the hot air gun 2 from sliding and rotating during the baking process. The above metal materials are preferably SUS304.

[0030] As shown in the appendix Figure 2 As shown in the figure, due to the changes in the building structure and the feeding bin structure in the front area of the new high-generation overflow method substrate glass furnace compared with the low-generation line body, the original chain hoist hanging method of the baking hot air gun is no longer applicable. Raw materials are stored in the front bin 3 of the furnace. The technical solution provided by this patent uses a movable hot air gun trolley 7 to support the hot air gun 2. After the natural gas and combustion-supporting air are pressure-adjusted and flow-regulated through the baking combustion tray 6, they enter the hot air gun 2 for mixed combustion and generate hot air, which is sprayed into the furnace through the feeding port 5 to uniformly and gently heat the furnace 1.

[0031] As Figure 3As shown in the figure, the front support 12 includes: a semi-circular support member 19; a first adjustment bolt 20 for adjusting the support height of the front support 12 for the hot air gun; and a cushion block 21 for fixedly installing the first adjustment bolt 20. The rib plate through hole at the lower end of the semi-circular support member 19 is penetrated by the first adjustment bolt 20, and fastening nuts are provided at both the upper and lower ends of the rib plate. The combined use of the first adjustment bolt 20 and the nuts can make the semi-circular support member 19 stop at different positions of the first adjustment bolt 20, thereby forming the adjustment of the overall height of the front support 12. The cushion block 21 is bolted to the vehicle frame 8, and the bottom of the first adjustment bolt 20 is welded to the cushion block 21. The first adjustment bolt 20 and the matching nut are used to finely adjust the height of the semi-circular support member 19.

[0032] In the technical solution of this patent, the extension leg 18 includes a support leg 22, and a second adjustment bolt 23 and an adjustment nut 24 for adjusting the height of the support leg 22 are provided below the support leg 22; a circular cushion block 25 is provided below the adjustment nut 24, and a circular insulating rubber pad 26 is provided below the circular cushion block 25. The extension leg 18 can effectively improve the stability of the overall device and eliminate the position movement caused by the vibration of the hot air gun itself during the operation.

[0033] In the technical solution of this patent, the casters 17 are four universal wheels wrapped with insulating rubber rings; the casters 17 are provided with a braking device, which is fixed to the vehicle frame by a bolt connection method. The setting of the braking device enables the trolley structure to obtain better fixation at a specific position. The extension leg 18 is connected to the vehicle frame 8 by a bolt fastening method. The support leg 22 is made of a rectangular pipe, preferably with a specification of 50*50*3mm and a material preferably SUS304; one end of the support leg 22 is bolted to the vehicle frame 8, and the other end is sleeved with the second adjustment bolt 23 / 24; the nut on the upper part of the adjustment bolt sleeve 23 / 24 is welded to the support leg 22, and the nut on the lower part is welded to the circular cushion block 25. The bolt specification is preferably M16 and the material is preferably SUS304. The circular insulating rubber pad 26 is bonded to the circular cushion block 25 with high-strength glue, and its function is to ensure the ground insulation of the hot air gun trolley. Adjust the adjustment bolt sleeve to an appropriate length to ensure that the extension leg 18 plays an ideal supporting and stabilizing role for the trolley in a static state, and the extension leg 18 can also be rotated, folded or disassembled according to the actual needs of the trolley. The barrel clamp 11 is a bolt clamp with an adjustable clamp diameter. On the one hand, when the hot air gun enters the fixed position, lock the clamp of the clamp ring to better fix the hot air gun. On the other hand, in the face of hot air guns of different models and sizes, the adjustable barrel clamp 11 has stronger practicability.

[0034] Advantages of the technical solution of the utility model patent: The hot air gun is carried and fixed by a bracket, which is stable and reliable as a whole during the operation process, fully matching the current situation that the original hanging method of the baking kiln hot air gun cannot be adopted due to the change of the front furnace structure of the high-generation substrate glass workshop. A movable trolley structure is adopted to support the baking kiln hot air gun, with reasonable design, flexible adjustment method, convenient movement and reliable function. Adjustable front and rear brackets are adopted, enabling the rapid adjustment of the position of the hot air gun and a higher matching degree with the kiln furnace. Extended legs with telescopic height are adopted, which are more stable and efficient in supporting and adjusting the hot air gun.
