[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The double-chamber kiln negative pressure air supply device provides two technical solutions:

[0028] like Figure 1-5 The first embodiment is shown: it includes two left and right kiln chambers 1, and both kiln chambers 1 are provided with multiple groups of spray guns 5, and the multiple groups of spray guns 5 are arranged along the circumference of the upper surface of the kiln chamber 1, and the spray guns 5 are fixed to the outside of the kiln chamber 1 by a quick installation mechanism, and the quick installation mechanism includes:

[0029] The pre-installation component 3 is used for pre-installing the spray gun 5. The pre-installation component 3 includes a fixed tube 31, and the fixed tube 31 is fixedly connected to the kiln chamber 1. Slide grooves 32 are provided on both sides of the surface of the fixed tube 31. Circular ring plates 33 are slidably connected to the two slide grooves 32. The circular ring plate 33 is sleeved on the outside of the fixed tube 31. A plurality of grooves 34 are provided on the annular surface of the circular ring plate 33 at equal distances, and a fixing rod 35 is fixedly connected inside the groove 34. A clamping plate 36 is rotatably connected to the surface of the fixing rod 35. A through groove 38 is provided inside the clamping plate 36, and the fixing rod 35 passes through the through groove 38. A torsion spring 37 is sleeved on the surface of the fixing rod 35 at the through groove 38. One end of the through groove 38 is fixedly connected to the surface of the fixing rod 35, and the other end of the through groove 38 is fixedly connected to the clamping plate 36.

[0030] The locking assembly 4 is arranged on the fixed tube 31, and the locking assembly 4 is used to drive the annular plate 33 to move so that the clamping plate 36 presses the spray gun 5. The locking assembly 4 includes a T-type threaded sleeve 41. The surface of the fixed tube 31 is provided with threads. The T-type threaded sleeve 41 is threadedly connected to the surface of the fixed tube 31. A handle 43 is fixedly connected to the surface of the T-type threaded sleeve 41. A plurality of L-shaped plates 42 are fixedly connected to the back side of the fixed tube 31 at equal distances along the circumferential direction, and the plurality of L-shaped plates 42 are clamped at the T-shaped head of the T-type threaded sleeve 41.

[0031] When the spray gun 5 needs to be disassembled, the fixing of the spray gun 5 can be quickly released by rotating the threaded sleeve 41, so that the inside of the spray gun 5 and its pipeline can be easily checked and the residual soot can be cleaned, thereby improving the practicality of the device when in use.

[0032] like Figure 3 and 4 A second embodiment is shown, which mainly differs from the first embodiment in that a sealing assembly 6 is provided between the spray gun 5 and the fixed tube 31 for sealing the docking position of the spray gun 5, and the sealing assembly 6 includes an annular groove 61 provided on the end face of the fixed tube 31, a sealing gasket 62 is clamped inside the annular groove 61, and a docking groove 63 matching the size of the end of the fixed tube 31 is provided on the end face of the spray gun 5.

[0033] A sealing assembly 6 adapted to the quick installation and removal mechanism is provided, so as to ensure the sealing of the joint after the spray gun 5 is fixed by the quick installation mechanism, thereby improving the reliability of the device when in use.

[0034] During installation, align the docking groove 63 with the end of the fixed tube 31. At this time, the end of the spray gun 5 is in the middle position of the multiple clamps 36. Move the spray gun 5 so that the spray gun 5 contacts the clamps 36, thereby pushing the clamps 36 to rotate. At this time, the end of the spray gun 5 can pass over the head of the clamps 36 and enter the interior of the multiple clamps 36. Under the action of the torsion spring 37, the clamps 36 are reset and the spray gun 5 is clamped. At this time, the spray gun 5 is pre-fixed. Then, the T-threaded sleeve 41 is rotated by the handle 43. The T-threaded sleeve 41 moves backward and the multiple clamps 36 are pressed against the spray gun 5. After pressing, the docking point between the spray gun 5 and the fixed tube 31 is sealed by the action of the sealing gasket 62. In addition, when disassembling, you only need to rotate the T-threaded sleeve 41 to release the clamps 36 from the spray gun 5.
