Description

Grain dryer with dust collecting device

The present invention relates to a grain dryer, and more particularly to a grain dryer having a dust collecting device.

Referring to Figures 1 and 2, a grain dryer includes a casing 5 defining a drying space 51, and a hot air device 6. The hot air device 6 includes a hot air blower 61 disposed on one side of the casing 5, a blower 62 disposed on the other side of the casing 5, and a duct group 63. The air duct group 63 is disposed in the drying space 51, and communicates with the hot air blower 61, the air blower 62 and the drying space 51, and can guide the hot air bending generated by the hot air blower 61 to conduct and guide the drying to the drying In the space 51, the time during which the hot air stays in the drying space 51 is delayed, and the effect of sufficiently drying the grain can be achieved. The hot air device 6 needs to transmit hot air to the drying space 51, and needs to discharge hot air. Therefore, a hot air flow from the hot air fan 61 to the exhaust fan 62 is formed in the drying space 51, thereby achieving dry grain. At the same time as the efficacy, impurities and dust adhering to the grain are discharged from the casing 5 through the air duct group 63 through the air duct group 63. However, since the grains in the drying space 51 are densely stacked, only the grain dust adjacent to the air channel group 63 may be discharged from the casing 5 by the suction force of the hot air flow, so the additional row The effect of dust is not obvious.

Accordingly, it is an object of the present invention to provide a grain dryer having a dust collecting device that enhances dust removal efficiency.

Accordingly, the grain dryer of the present invention having a dust collecting device comprises a casing, a hot air dust collecting unit, and a main dust collecting unit. The casing defines a hollow chamber and includes a partition separating the hollow chamber from a dry space above and a valley space below. The baffle has a plurality of openings for the grain to fall from the drying space into the trough space. The hot air dust collecting unit comprises a hot air fan disposed on one side of the casing, an air blower disposed on the other side of the casing, and a wind tunnel group. The air duct group is disposed in the drying space and communicates with the hot air blower, the air blower and the drying space. Through the suction of the exhaust fan, the dust in the dry space can be discharged from the air blower through the air duct group. The main dust collection unit includes a dust collecting pipe that communicates the collection space with the exhaust fan. Through the suction of the exhaust fan, the dust located in the valley space can be discharged from the exhaust fan through the dust collecting pipe.

The effect of the invention is that the hot air dust collecting unit firstly discharges the dust in the dry space, and the openings can make the grain fall into the grain space from the drying space with a small flow, and match The main dust collecting unit discharges the dust that slowly falls into the gathering space from the exhaust fan through the dust collecting pipe, so that the dust can be discharged more completely, and the dust removing effect is successfully enhanced.

Other features and advantages of the present invention will be apparent from the following description of the accompanying drawings in which: FIG. BRIEF DESCRIPTION OF THE DRAWINGS Figure 3 is a partial cross-sectional view showing a preferred embodiment of a grain dryer having a dust collecting device of the present invention; and Figure 4 is a partial cross-sectional view of the preferred embodiment.

Referring to Figures 3 and 4, a preferred embodiment of the grain dryer having a dust collecting device of the present invention comprises a casing 1, a plurality of stapling claws 2, a hot air dust collecting unit 3, and a main dust collecting unit 4.

The casing 1 defines a hollow chamber 11 and includes a partition 12 separating the hollow chamber 11 from a drying space 111 located above and a valley space 112 located below. The partition 12 has a plurality of openings 121 through which the grain falls from the drying space 111 into the valley space 112.

The claws 2 are rotatably disposed adjacent to the openings 121, respectively, and are located in the drying space 111, and the grain located in the drying space 111 can be dislodged and fall into the valley space 112. Through the picking claws 2, the flow rate of the grain falling into the valley space 112 from the drying space 111 can be controlled to be a slow and uniform small flow rate, and the time during which the grain stays in the drying space 111 can be increased, so that the grain can be Dry faster. Since the structure of the claws 2 and the means for controlling the flow rate of the grain are well understood by those skilled in the art and are not characteristic of the present invention, detailed means and operations thereof will not be described herein.

The hot air dust collecting unit 3 includes a hot air blower 31 disposed on one side of the casing 1, an air blower 32 disposed on the other side of the casing 1, and a duct group 33. The air channel group 33 is disposed in the drying space 111, and communicates with the hot air fan 31, the air extractor 32 and the drying space 111, and has a plurality of hot air ducts 331 that communicate with the hot air fan 31 and the drying space 111, and multiple connections. The drying space 111 and the exhaust duct 332 of the exhaust fan 32.

The hot air blower 31 outputs hot air to the hot air ducts 331 , and the suction air is sucked by the air blower 32 to guide the hot air to flow into the dry space 111 connecting the hot air ducts 331 and the air exhaust ducts 332 . In the exhaust duct 332, at the same time, a portion of the grain dust located in the drying space 111 can be discharged from the exhaust fan 32 via the duct group 33.

It is worth mentioning that at this time, only a small amount of grain dust adjacent to the exhaust ducts 332 can be initially discharged.

The main dust collecting unit 4 includes a dust collecting pipe 41 connecting the collecting space 112 and the exhaust fan 32, and a dust collecting inlet 42. The dust collecting inlet 42 is defined by the dust collecting pipe 41, and is formed on one side of the casing 1 corresponding to the exhaust fan 32, and communicates with the collecting space 112.

Through the suction of the exhaust fan 32, and through the openings 121 and the claws 2, the grain can be dropped into the valley space 112 from the drying space 111 with a small flow rate, so that the suction can be slowed down. The dust entering the collection space 112 is discharged from the dust collection inlet 42 through the dust collection duct 41, so that the dust can be discharged more completely to the collection space 112, and the drainage is successfully enhanced. Dust effect.

In summary, the hot air dust collection unit 3 is initially placed. The dust in the drying space 111 is discharged, and the openings 121 and the scraping claws 2 can cause the grain to fall into the grain space 112 from the drying space 111 with a small flow rate, and match the main dust collection. The unit 4 causes the grain dust that gradually falls into the collection space 112 to be discharged from the suction fan 32 through the dust collecting tube 41, so that the dust can be more completely discharged, and the dust removal effect is successfully enhanced, so that the present invention can be achieved. The purpose of the invention.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, and the simple equivalent changes and modifications made by the scope of the patent application and the patent specification of the present invention are It is still within the scope of the invention patent.
