[0021] 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.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A biomass hot air furnace supporting a grain dryer comprises a shell 1, a support leg 2 is fixedly connected to the surface of the shell 1, which supports the shell 1 as a whole and prevents the shell 1 from collapsing, a cover plate 3 is fixedly connected to the surface of the shell 1, which protects the auger motor 4 and prevents it from being accidentally touched, and the auger motor 4 is arranged inside the cover plate 3 to provide power for the system, an air inlet 5 is provided on the surface of the shell 1 for the entry of air, which is convenient for the use of a heat exchanger blower 9, a burner 6 is provided on the surface of the shell 1 to ignite and heat the interior and heat the heat exchange tube 10, a hot air outlet 7 is provided on the surface of the shell 1, and the hot air comes out from here, and a control door panel 8 is movably connected to the surface of the shell 1 to protect the main control room, A heat exchanger blower 9 is arranged inside the shell 1 to provide air for the system for subsequent heating. A heat exchange tube 10 is arranged inside the shell 1 to heat the air generated by the heat exchanger blower 9. A handle 11 is fixedly connected to the surface of the control door panel 8 to facilitate the operator to open the control door panel 8. A fixing plate 12 is fixedly connected to the surface of the shell 1 to fix the closed control door panel 8. A rotating bolt 13 is fixedly connected to the surface of the control door panel 8 to limit the rotation of the fixing block 14 while connecting the fixing block 14. The surface of the rotating bolt 13 is rotatably connected to the fixing block 14 to fix or open the control door panel 8. A manual turning handle 15 is fixedly connected to the surface of the fixing block 14 to facilitate the rotation of the fixing block 14.

[0024] Furthermore, the support legs 2 are in six groups, the cross-section of the support legs 2 is in an "L" shape, the support legs 2 are fixedly connected to the lower surface of the outer shell 1, and the six groups of support legs 2 are evenly distributed on both sides of the lower surface of the outer shell 1, providing support for the entire outer shell 1 to prevent the outer shell 1 from collapsing during operation.

[0025] Furthermore, a vent is provided on the surface of the burner 6 . The burner 6 is used to heat the heat exchange tubes 10 inside the housing 1 , and normal air circulation is required to improve the heating efficiency of the heat exchange tubes 10 .

[0026] Furthermore, ventilation holes are evenly arranged on the surface of the hot air outlet 7. The evenly arranged ventilation holes are conducive to the discharge of hot air and are more concentrated. At the same time, the large area of ​​the hot air outlet 7 allows the hot air to circulate faster.

[0027] Furthermore, the heat exchange tubes 10 are evenly distributed inside the shell 1. A large number of heat exchange tubes 10 enable the wind blown out of the heat exchanger blower 9 to be heated faster. At the same time, because a large number of heat exchange tubes 10 are placed inside the shell 1, the wind flow speed will be blocked and slowed down accordingly, which is convenient for heating the wind.

[0028] Furthermore, the control door panel 8 is fixedly connected through the surface of the fixing block 14 and the fixing plate 12. When the control door panel 8 is closed, the fixing block 14 hooks the side of the fixing plate 12 to fix the control door panel 8 and prevent the control door panel 8 from being easily opened. The lower surface of the fixing block 14 is inclined to better hook the fixing plate 12.

[0029] Furthermore, the manual handle 15 is in the shape of a "9", and the fixed block 14 is rotatably connected through the surface of the manual handle 15 and the rotating bolt 13. The manual handle 15 is rotated to drive the fixed block 14 to rotate, thereby controlling the fixing effect of the control door panel 8. The fixed block 14 is fixed when it hooks the fixed plate 12, and is released when it is rotated and loosened.

[0030] Working principle: When the entire hot air stove is used, first place the shell 1 so that the supporting feet 2 touch the ground. Then turn on the burner 6 to heat the heat exchange tube 10 inside the shell 1. After a period of time, turn the manual handle 15 to make the fixing block 14 leave the surface of the fixing plate 12, then hold the handle 11 to open the control door panel 8, turn on the main control button, close the control door panel 8, and then turn the fixing block 14 so that the fixing block 14 hooks the fixing plate 12. After confirming the fixation, ensure the indoor air circulation, turn on the auger motor 4 located inside the cover plate 3, and the entire hot air stove starts to operate normally.

[0031] When the use is finished, turn off the auger motor 4 inside the cover plate 3, then turn off the burner 6, turn the manual turning handle 15 to make the fixing block 14 leave the fixing plate 12, hold the handle 11 to open the control door panel 8, turn off the main control button, then close the control door panel 8, turn the fixing block 14, and fix the position.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
