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.
[0022] The utility model provides Figure 1-4 An energy-saving drying room for printing and coating production shown in the figure comprises a drying room 1 and an incinerator 11, a burner 2 is arranged on one side of the incinerator 11, a fixing component for fixing the position of the burner 2 is arranged at the connection between the incinerator 11 and the burner 2, the fixing component comprises a fixing ring 3 sleeved on one side of the burner 2, a fixing block 6 is fixedly connected to one side of the incinerator 11 horizontally and centrally symmetrically, a positioning block 4 for limiting and releasing the movement of the fixing ring 3 is arranged on one side of the fixing block 6, a moving part for moving the position of the positioning block 4 is arranged on one side of the positioning block 4, and a limiting part for limiting the moving direction of the positioning block 4 is arranged on one side of the fixing block 6.
[0023] It should be noted that the incinerator 11 is a device for treating waste gas generated in industrial production. Its function is to burn harmful substances in the waste gas at high temperature, oxidize organic pollutants into carbon dioxide and water vapor, and convert inorganic harmful substances into harmless compounds or remove them in solid form. By treating and reducing the pollutant emissions of the waste gas, the requirements of environmental protection and emission standards are met. The burner 2 is a mechanical device that converts fuel into thermal energy, thereby heating the incinerator 11 through the burner 2; the fixed ring 3 is annular, and its fixed sleeve is arranged at the output end of the burner 2. When the position of the burner 2 needs to be fixed, the position of the burner 2 is fixed by the fixed ring 3. The positioning block 4 is set to be semi-annular, and the diameter of its inner wall is adapted to the diameter of the outer wall of the fixing ring 3, and the cross-section of the positioning block 4 is set to be L-shaped. When in use, the fixing ring 3 is clamped by the positioning block 4 and the outer wall of the incinerator 11 to fix the position of the fixing ring 3.
[0024] Furthermore, when the burner 2 needs to be fixed, the fixing ring 3 mounted on the burner 2 is moved to fit with the incinerator 11, and then the positioning block 4 is driven to move by the moving part, and the fixing ring 3 is clamped between the outer wall of the incinerator 11 and the positioning block 4 by the L-shaped positioning block 4, so as to complete the fixation of the position of the fixing ring 3. The position of the burner 2 is fixed by the fixing ring 3, avoiding the use of bolts when fixing the burner 2, thereby avoiding the situation where the burner 2 cannot be disassembled.
[0025] Specifically, the moving part includes a pull rod 5 fixedly connected to one side of the positioning block 4, the pull rod 5 is inserted and connected to the middle of the fixed block 6, and the end of the fixed block 6 away from the pull rod 5 is fixedly connected to a handle 7, and the handle 7 is set to be L-shaped.
[0026] Specifically, the moving part also includes a spring 8 fixedly connected to one side of the positioning block 4 , one end of the spring 8 away from the positioning block 4 is fixedly connected to one side of the fixed block 6 , and the pull rod 5 is inserted and connected to the middle of the spring 8 .
[0027] It should be noted that the fixed block 6 is fixedly connected to the outer wall of the incinerator 11, and a hole for the pull rod 5 to pass through is opened on the fixed block 6. The opened hole is adapted to the pull rod 5 to prevent the pull rod 5 from rotating in the hole. The widths of the handle 7 and the positioning block 4 are both larger than the width of the hole, thereby preventing the pull rod 5 from passing through the hole. This setting limits the moving distance of the pull rod 5. The handle 7 is set to be L-shaped, and the width of the handle 7 is larger than the width of the fixed block 6. When the position of the handle 7 needs to be moved, the handle 7 is moved by the part of the handle 7 that exceeds the fixed block 6, thereby realizing the movement of the positioning block 4 by the handle 7. The spring 8 is used to push the positioning block 4 to the side away from the handle 7.
[0028] Furthermore, when it is necessary to fix the position of the fixing ring 3, the positioning block 4 is first moved toward the side of the spring 8 through the handle 7, the spring 8 is squeezed and deformed, and then the fixing ring 3 is moved to fit with the incinerator 11, and then the pulling force on the handle 7 is released, the spring 8 recovers its deformation, and the positioning block 4 is pushed toward the side of the fixing ring 3, so that the fixing ring 3 is clamped and fixed on one side of the incinerator 11 through the positioning block 4, and its position is fixed; when it is necessary to separate the fixing ring 3 from the incinerator 11, the positioning block 4 is driven by the handle 7 to separate from the fixing ring 3, and the clamping of the fixing ring 3 is lost, thereby realizing the separation of the fixing ring 3 from the incinerator 11.
[0029] Specifically, the limiting member includes a guide column 9 which is horizontally and centrally symmetrically fixedly connected to one side of the fixing block 6. A guide groove 10 for limiting the rotation of the positioning block 4 is horizontally and centrally symmetrically provided on one side of the positioning block 4. One end of the guide column 9 is inserted and connected to the interior of the positioning block 4.
[0030] It should be noted that the guide columns 9 are used to strengthen the top and bottom of the positioning block 4 and limit the movement of the positioning block 4, so that when the positioning block 4 is in use, the two guide columns 9 inserted and connected on one side of the positioning block 4 can be used to limit the rotation of the positioning block 4.

[0032] It should be noted that the heated gas after incineration in the incinerator 11 is output through the heat outlet pipe 12, and then the gas is input into the mixing chamber 14 through the connecting pipe 13, and finally the hot gas is transported to the bottom of the drying room 1 through the heat delivery pipe 15 on the mixing chamber 14, so as to realize the reuse of the heated gas.

[0034] It should be noted that after the hot air input into the drying room 1 is cooled, the gas is transported to the mixing chamber 14 through the first return air pipe 16, and the gas input through the connecting pipe 13 and the first return air pipe 16 is mixed through the mixing chamber 14 to cool the gas input through the connecting pipe 13 to avoid over-high temperature.
[0035] Specifically, one end of the heat outlet pipe 12 away from the incinerator 11 is fixedly connected to the exhaust gas preheater 17, the output end of the exhaust gas preheater 17 includes a waste heat output end and a return air output end, the input end of the exhaust gas preheater 17 includes a hot air input end and a return air input end, the top of the drying room 1 is interspersed with a second return air pipe 23, the second return air pipe 23 is fixedly connected to the return air input end of the exhaust gas preheater 17, the return air output end of the exhaust gas preheater 17 is fixedly connected to the air supply pipe 18, and the end of the air supply pipe 18 away from the exhaust gas preheater 17 is fixedly connected to the input end of the incinerator 11.
[0036] It should be noted that the second air return pipe 23 is used to directly input the gas in the drying room 1 to the waste gas preheater 17, and then the hot gas input to the waste gas preheater 17 through the heat outlet pipe 12 is used to preheat the gas input to the waste gas preheater 17 through the second air return pipe 23, and finally the preheated gas is heated to the incinerator 11 through the gas supply pipe 18.
[0037] Specifically, the waste heat output end of the waste gas preheater 17 is fixedly connected to the waste gas discharge pipe 21 , and one end of the waste gas discharge pipe 21 away from the waste gas preheater 17 is fixedly connected to the waste heat exchanger 20 .
[0038] It should be noted that the gas heat-exchanged in the exhaust gas preheater 17 is input to the waste heat exchanger 20 through the exhaust gas discharge pipe 21 , and finally the gas is discharged through the waste heat exchanger 20 .
[0039] Specifically, the input end of the waste heat exchanger 20 is fixedly connected to the air intake pipe 19 , the output end of the waste heat exchanger 20 is fixedly connected to the ventilation pipe 22 , and one end of the ventilation pipe 22 away from the waste heat exchanger 20 is fixedly connected to the ventilation inlet end of the mixing chamber 14 .
[0040] It should be noted that the end of the air inlet pipe 19 away from the waste heat exchanger 20 is connected to the coating room, and the gas in the coating room is input into the waste heat exchanger 20. The exhaust gas input into the waste heat exchanger 20 through the exhaust gas discharge pipe 21 heats the gas input into the waste heat exchanger 20 through the air inlet pipe 19. Finally, the heated gas is input into the mixing chamber 14 through the ventilation pipe 22, thereby completing the input of fresh gas into the drying room 1.
