[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 As shown in Embodiment 1 of this utility model, a dual-heat-source heating and frying device includes a frame 1, a protective cover 6 fixed to the frame 1, a rotating drum 2 rotatably disposed within the protective cover 6, an open flame heating device 7 disposed within the protective cover 6 for heating the rotating drum 2, a hot air heating device 4 connected to one end of the rotating drum 2, and a drive device for driving the rotating drum 2 to rotate. The rotating drum 2 is equipped with blades 5 for stirring the materials; the hot air heating device 4 is disposed at the bottom of the protective cover 6 and fixed to the frame 1; the drive device is fixed to the lower part of the frame 1; and the drive device adopts a gear drive mechanism or a belt drive mechanism, that is, the drive device uses a rotating motor and a driving gear disposed at the output end of the motor, and the rotating drum 2 is provided with a driven gear meshing with the driving gear; or the drive device uses a rotating motor and a driving pulley disposed at the output end of the motor, and the rotating drum 2 is provided with a driven pulley connected to the driving pulley via a belt. Furthermore, the outlet end of the hot air heating device 4 is rotatably engaged with the rotating drum 2, thereby not hindering the rotation of the rotating drum 2.

[0021] In addition, the frame is also equipped with rollers to support the rotating drum 2. The two ends of the rotating drum 2 are fitted with rolling rings to rotate with the rollers, thereby supporting the rotation of the rotating drum.

[0022] Example 2 differs from Example 1 in that, as Figure 2As shown, the open flame heating device 7 includes a permanent flame outlet 73, a heating flame head 75, an igniter 71 that cooperates with the permanent flame outlet 73, and a flame detector 72 for detecting the flame, all located at the bottom of the protective cover 6. The permanent flame outlet 73 and the heating flame head 75 are connected to a gas supply pipe for supplying gas to them. The flame outlets of the permanent flame outlet 73 and the heating flame head 75 are fixed facing the bottom of the rotating drum. The igniter 71 is a conventional gas igniter; it cooperates with the permanent flame outlet 73 to ignite it. The flame detector 72 is a conventional ultraviolet flame detector; it is fixed to the frame at the bottom of the protective cover 6 to detect whether the permanent flame outlet 73 is ignited. After the permanent flame outlet 73 is ignited, the heating flame head 75 is ignited after gas is supplied.

[0023] Furthermore, such as Figure 2 As shown, the heating burners 75 have at least two rows, each row of which is connected to a gas supply branch pipe, and each gas supply branch pipe is equipped with a control valve 74. The permanent flame outlet 73 is also connected to a gas supply branch pipe. Both the gas supply branch pipe of the permanent flame outlet 73 and the gas supply branch pipes of the heating burners 75 are connected to a main gas supply pipe, which is connected to a gas source. Each gas supply branch pipe is equipped with a control valve 74. During ignition, the control valve 74 on the gas supply branch pipe of the permanent flame outlet 73 is first opened, allowing the permanent flame outlet 73 to be ignited by the igniter 71. Then, according to the needs of the material, the control valve 74 on the gas supply branch pipe of the heating burners 75 can be opened to control the gas supply to all heating burners 75, or one or more rows of heating burners 75, for combustion.

[0024] Example 3 differs from Example 2 in that, as Figure 1 As shown, the hot air heating device 4 includes a burner 41, an induced draft fan 42 connected to the burner 41, and a hot air duct 44 connected to the outlet of the induced draft fan 42. The burner 41 and the induced draft fan 42 are fixed outside the frame. Both the burner 41 and the induced draft fan 42 adopt existing structures. The inlet of the induced draft fan 42 is connected to the burner 41 for drawing in hot air. The hot air duct 44, connected to the outlet of the induced draft fan 42, extends into the heating drum 2 to deliver hot air into the drum 2. Furthermore, the outer cylinder of the hot air duct 44 is rotatably connected to the heating drum 2 via bearings.

[0025] Furthermore, such as Figure 1 As shown, a hot air thermometer 43 is installed on the hot air duct 44 to monitor the hot air temperature, so as to facilitate the adjustment of the heating temperature of the burner 41.

[0026] Example 4 differs from Example 3 in that, as Figure 1As shown, the protective cover 6 has an insulation layer inside; and both ends of the protective cover 6 have outlets through which the rotating drum 2 passes. Specifically, both ends of the rotating drum 2 have tapered cylinders with narrow ends, and the smaller ends of the tapered cylinders are connected to cylindrical cylinders. The cylindrical cylinder near the hot air heating device 4 is sleeved on the outside of the hot air duct 44 and is rotatably connected to the hot air duct 44 through bearings, and the clearance fit between the cylindrical cylinder and the outlet of the protective cover 6 does not affect the rotation of the rotating drum 2. The end of the rotating drum 2 away from the hot air heating device 4 is fitted with the corresponding outlet through a tapered cylinder with a clearance fit. Both ends of the protective cover 6 have closed covers. The cylindrical cylinders at both ends are located inside the corresponding closed covers. Furthermore, the rolling rings are set on the cylindrical cylinders at both ends and rotatably engage with the support rollers on the frame.

[0027] Furthermore, such as Figure 1 As shown, the closed shroud near the hot air heating device 4 is fixedly connected to the hot air duct 44, and the closed shroud away from the hot air heating device 4 is provided with a feed hopper 9 for feeding the rotating drum 2. The end of the rotating drum 2 that cooperates with the feed hopper 9 is an open opening, which not only does not hinder the rotation of the rotating drum 2, but also does not hinder the feeding of material by the feed hopper 9 during the rotation of the rotating drum 2.

[0028] Example 5 differs from Example 4 in that, as Figure 1 As shown, a discharge hopper 10 for discharging material is also provided on the closed cover near the open opening of the rotating drum 2. The closed cover has an opening through which the discharge hopper 10 passes; the discharge hopper 10 is rotatably connected to the opening of the closed cover. Specifically, a rotating shaft is provided on the lower side of the opening, and the bottom center of the discharge hopper 10 is rotatably connected to the closed cover via the rotating shaft. When the discharge hopper 10 rotates upward, the inlet of the discharge hopper 10 is located just below the open opening of the rotating drum 2, and material is discharged by the reverse rotation of the rotating drum 2. When no material is being discharged, the discharge hopper 10 rotates downward, causing the upper half of the discharge hopper 10 to tilt upward, and then the upper end and / or the side edges of the bottom plate of the discharge hopper 10 abut against the edge of the opening, thereby closing the opening.

[0029] In addition, a door panel 11 is hinged to the closed cover near the opening of the rotating drum 2, which makes it easy to open the door panel 11 to observe and inspect the internal condition.

[0030] Example 6 differs from Example 5 in that, as Figure 1 As shown, a rotary drum thermometer 8 is inserted into the rotary drum 2 on the closed cover to detect the heating temperature inside the rotary drum 2.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some or all of the technical features thereof, within the spirit and principles of the present invention, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and should all be included within the protection scope of the present invention.
