[0023] Example 1

[0024] like Figs. 1-2 As shown, this embodiment provides a hot air blower for a silkworm shed, comprising a furnace body 1, wherein a grate 2 is provided in the furnace body 1, the space above the grate 2 in the furnace body 1 is a furnace 3, the space below the grate 2 in the furnace body 1 is a dust collecting chamber 4, a blower 11 is installed on the outer wall of the furnace body 1, and the blower 11 is connected to the furnace 3 and the dust collecting chamber 4 respectively; an external circulation smoke pipe 9 and a plurality of ventilation pipes 5 are provided on the furnace 3, each of the ventilation pipes 5 is connected to a wind tube 7 through a hose 6, and the wind tube 7 is provided with a plurality of air outlets 8.

[0025] The ventilation pipe 5 and the air duct 7 are used in conjunction. When in use, the air duct 7 can be placed at different locations within the silkworm shed. Hot air is discharged from the air outlet 8 of the air duct 7. The hot air rises from the ground and fills the entire silkworm shed, heating the shed. Furthermore, multiple air ducts 7 can achieve uniform air supply at multiple locations, ensuring a uniform temperature in the shed and improving thermal efficiency. A blower 11 can blow outside air into the furnace 3, where heat exchange occurs, quickly and efficiently heating the air within the shed and reducing energy consumption.

[0026] In this embodiment, the inner wall of the hearth 3 is provided with an arc-shaped air deflector 13. The air deflector 13 can allow the air blown by the air blower 11 to enter the central part of the hearth 3, thereby accelerating the heat exchange speed. At the same time, the air deflector 13 can guide the flame of the fuel combustion to be located in the middle of the hearth 3, thereby improving the heating efficiency.

[0027] In this embodiment, the outer circulating flue 9 is provided with an induced draft fan 10, and the ventilation pipe 5 is provided with an adjusting valve 12. The outer circulating flue 9 can make the flue gas circulate in the hearth 3, thereby fully utilizing the heat of the flue gas. The adjusting valve 12 can adjust the air volume of the hot air, thereby adjusting the temperature in the silkworm shed, and avoiding excessively high or low temperature.

[0028] In this embodiment, the hearth 3 is provided with a filter assembly, which includes a fixed frame and a filter screen 15 detachably installed in the fixed frame. The fixed frame is fixedly installed on the inner wall of the hearth 3. The filter assembly can filter the hot air, thereby reducing the content of dust and other impurities in the hot air, and avoiding that a large amount of dust and other impurities enter the silkworm shed to affect the growth of silkworms. The filter screen 15 is detachable, thereby being convenient to replace and maintain, and ensuring the cleanliness of the hot air entering the silkworm shed.

[0029] In this embodiment, the hearth 3 is provided with a vibrating member, which includes a rotating shaft 16 installed on the furnace body 1, a protrusion 17 installed on the rotating shaft 16, and a motor connected with the rotating shaft 16. The protrusion 17 can contact the filter screen 15. The motor is installed on the outer wall of the furnace body 1, and drives the rotating shaft 16 to rotate, so that the protrusion 17 repeatedly collides with the filter screen 15, thereby causing the dust on the filter screen 15 to fall off, and preventing the filter screen 15 from being blocked to affect the ventilation condition and the filtering effect.

[0030] In this embodiment, the top of the grate 2 is provided with an arched plate 14, and a plurality of through holes are formed in the arched plate 14. Since the fuel is added into the hearth for combustion, the fuel accumulated in the middle of the grate 2 is thick, which can affect the fuel combustion. The arched plate 14 can support the fuel in the middle, so that the air can enter the fuel, thereby accelerating the fuel combustion speed and combustion efficiency, and improving the thermal efficiency.

[0031] In this embodiment, a plurality of heat collecting fins (not shown in the figure) are further arranged in the hearth 3. The heat collecting fins are embedded in the inner wall of the hearth 3, and can absorb heat. Even if the hearth 3 is not heated, the stored heat can still provide heat for a long time. At the same time, the hearth 3 has good heat preservation effect, thereby reducing heat loss.

[0032] The working principle of the hot air machine for silkworm shed is that fuel is put into the furnace 3 to burn, the air duct 7 is placed in a suitable position in the silkworm shed, the air blower 11 is started to blow air into the furnace 3, the air is heated in the furnace 3 after entering, the heated air enters the air duct 7 from the ventilation pipe 5, and the heated air is discharged from the air outlet 8 of the air duct 7, the heated air rises from the ground and fills the whole silkworm shed, and the silkworm shed is heated.

[0033] The preferred embodiments of the present application are merely used for the description of the present application, but not for limiting the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
