[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Gas-fired heat preservation furnace, such as Figures 1-4 As shown, the furnace includes a furnace body 1, a base 2, a motor 3, a lead screw 4, a sliding frame 5, a smoke guide pipe 6, a filter pipe 7, a placement rack 8, filter plates 9, and an air inlet pipe 10. The base 2 is connected to the lower left side of the furnace body 1, and the motor 3 is connected to the left side of the base 2. The lead screw 4 is connected to the output shaft of the motor 3 and is rotatably connected to the base 2. The sliding frame 5 is threaded onto the lead screw 4 and is slidably connected to the base 2. The right side of the sliding frame 5 is arc-shaped to facilitate the placement and pushing of charcoal. The sliding frame 5 is made of steel and has good strength, high temperature resistance, and wear resistance. The smoke guide pipe 6 is connected to the upper inner side of the furnace body 1, and the filter pipe 7 is connected to the tail end of the smoke guide pipe 6. The placement rack 8 is clamped onto the filter pipe 7. The placement rack 8 has two handles on the front side for easy gripping and pulling. Three filter plates 9 are clamped onto the placement rack 8. The air inlet pipe 10 is integrally formed and connected to the lower front part of the furnace body 1.

[0022] When furnace body 1 is needed, this device can be used to bring furnace body 1 and base 2 into contact with the ground. The filter plate 9 is then snapped into place with the placement rack 8. The placement rack 8 is then lifted using the handle and snapped into place with the filter tube 7 for installation. Charcoal is then placed on the sliding rack 5, and lit charcoal is placed on top. The right side of the sliding rack 5 is arc-shaped for easy placement and movement of the charcoal. The sliding rack 5 is made of steel, possessing good strength, high temperature resistance, and wear resistance. Next, the motor 3 on base 2 is started. The motor 3 drives the lead screw 4 to rotate, causing the sliding rack 5 to move and contact the furnace body 1, thus conveying the charcoal for combustion. Alternatively, gas can be connected to the gas inlet pipe 10, allowing the gas to enter the furnace body 1 for combustion. This allows for use via either charcoal combustion or gas combustion, combining two combustion methods for easy switching. The device is flexible and convenient to use. During the process, flue gas is generated. The flue gas enters the flue pipe 6 to prevent heat loss and for insulation, and then enters the filter pipe 7. The filter plate 9 on the placement rack 8 treats the solid particles and other pollutants in the flue gas. The treated flue gas is discharged from the filter pipe 7, thus treating the flue gas generated by combustion and reducing environmental pollution. When the filter plate 9 has been used for a long time, the placement rack 8 can be pulled off the filter pipe 7 by the handle, and then the filter plate 9 can be removed for cleaning or replacement. After cleaning or replacing the filter plate 9, it can be snapped back onto the placement rack 8. Then, the placement rack 8 can be snapped back onto the filter pipe 7 for use. This allows for the installation and removal of the placement rack 8 and the filter plate 9, facilitating the replacement and cleaning of the filter plate 9. After use, the motor 3 is started to operate in reverse, causing the lead screw 4 to rotate in reverse. Under the action of the thread, the sliding rack 5 moves in reverse, thereby removing the ash. Then, the motor 3 is turned off, and the ash can be cleaned.
