Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grain dryers, in particular to a grain dryer with a shutter type dust removal device. Background Art
[0002] Circulating grain dryers produce a lot of impurities when drying grain, such as grain husks, grain fluff, and weeds. These impurities must be continuously discharged from the dryer during the circulating drying process. Otherwise, they will bring many adverse factors to the drying process (such as blockage, poor feeding and discharge, excessive dust and impurities during discharge, and in serious cases, fire in the dryer).
[0003] Existing dust removal methods for circulating dryers vary widely, each offering its own unique approach. Generally speaking, these methods fall into the following categories: 1. Using a hot air blower to remove dust, but this is not ideal; 2. Adding a dust removal device to the top cover, which also fails to produce satisfactory results; 3. Adding a dust removal device to the circulating grain duct, which also fails to produce satisfactory results.
[0004] The reason is that during the circulation of grains, the following phenomena occur: 1. When the hot air blower is used for dust removal, the grains have a certain thickness in the drying layer, and only the impurities discharged are on the surface; 2. When removing dust on the top cover, although the grains are in a scattered state when entering the dryer from the upper grain channel (upper auger), impurities can float, but due to the strong continuity of the grain dispersion, floating objects are easily suppressed and brought into the machine; 3. Dust removal on the circulating grain channel is limited by the main space, so that only the surface layer of impurities in the grains can be discharged out of the dryer. Utility Model Content
[0005] The purpose of the utility model is to provide a grain dryer with a shutter-type dust removal device to solve the problems raised in the above background technology.
[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0010] Louvers, the louvers are laid at the ventilation opening and inclined toward the upper grain channel;
[0011] A dust removal assembly is configured to draw airflow from between the louvers into the upper grain channel when grain jumps and slides over the louvers, so that the airflow carries impurities into the dust removal assembly and then carries them out through the dust removal assembly;
[0012] The material throwing component is used to catch the dust-removed grain falling from the discharge port of the upper grain channel and throw it out.
[0013] Preferably, the dust removal component includes a dust removal air inlet pipe arranged on the upper grain duct, a dust removal fan arranged on the dust removal air inlet pipe, a dust removal air outlet pipe arranged on the dust removal fan, and a dust removal air outlet opened on the dust removal air outlet pipe.

The dust removal component includes a dust removal air inlet pipe arranged on the upper grain duct, a dust removal fan arranged on the dust removal air inlet pipe, a dust removal air outlet pipe arranged on the dust removal fan and a dust removal air outlet opened on the dust removal air outlet pipe. The utility model separates the grain from the impurities when sliding over the louvers through the arrangement of the louvers, and inhales air through the dust removal fan. Under the action of the dust removal fan, external air flow enters the gaps between the louvers at the bottom of the upper grain duct, driving the impurities to move toward the dust removal fan, and the impurities are quickly discharged through the dust removal air outlet. The arrangement of the material throwing component allows the grain to be evenly thrown out after dust removal, thereby evenly falling into the drying box, discharge bin and other equipment, avoiding accumulation in the drying box, discharge bin and other equipment.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] See also Figures 1 to 4 , the utility model provides a technical solution:
[0028] A grain dryer with a shutter-type dust removal device, comprising:
[0029] The upper grain channel 1 is used to transport grain. The upper grain channel 1 is tilted so that the grain moves obliquely downward in the upper grain channel 1 and leaks out from the discharge port 10 at the bottom. The upper grain channel 1 is a rectangular parallelepiped with an inner size of 1500×260×200 and is made of stainless steel.
[0030] The ventilation opening 2 is opened on the bottom wall of the upper grain channel 1.
[0031] The louvers 3 are laid at the vents 2 and tilted toward the upper grain channel 1. The louvers 3 are fixedly connected to the bottom wall of the inner tube of the upper grain channel 1 by welding or the like. There are several louvers 3, and the specific number can be selected according to actual usage. The raised end of the upper louver 3 covers the unraised end of the adjacent lower louver 3 to prevent food from leaking out from between the louvers 3 during the sliding process on the louvers 3.
[0032] The dust removal component includes a dust removal air inlet pipe 4, a dust removal air outlet pipe 5, a dust removal air outlet 6 and a dust removal fan 7. A window is opened on the upper plane of the upper grain channel 1. Its size is consistent with the size of the vent 2 and the position corresponds. The dust removal air inlet pipe 4 is arranged at the window of the upper grain channel 1. The dust removal air inlet pipe 4 is fixedly connected to the upper grain channel 1 by setting bolts or welding. The dust removal fan 7 is arranged on the dust removal air inlet pipe 4. The dust removal fan 7 is fixedly connected to the dust removal air inlet pipe 4 by setting bolts. The air duct 5 is arranged on the dust removal fan 7, and the dust removal air outlet duct 5 is fixedly connected to the dust removal fan 7 by setting bolts or welding. The dust removal air outlet 6 is opened on the dust removal air outlet duct 5. The dust removal fan 7 is used to inhale air, so that the dust removal fan 7 sucks the air flow from the gaps between the louvers 3. When the grain slides over the louvers 3, the air flow blows through the grain to blow up impurities such as dust, which are sucked into the dust removal air inlet duct 4 and finally discharged from the dust removal air outlet 6. The dust-removed grain continues to slide to the lower feed port 10.
[0033] Both the dust removal air inlet pipe 4 and the upper grain duct 1 are provided with observation plates, which are movably connected to the dust removal air inlet pipe 4 or the upper grain duct 1. Threaded holes are provided on the observation plates, which can be fixed by inserting screws. The inside of the dust removal air inlet pipe 4 or the upper grain duct 1 can be observed by pulling open the observation plates.
[0034] A material throwing assembly is provided at the discharge port 10 of the upper grain channel 1, and the material throwing assembly includes a material throwing motor 8 and a throwing plate 9. The material throwing motor 8 is provided on the upper grain channel 1, and the material throwing motor 8 is fixedly connected to the upper grain channel 1 by setting bolts, etc. The material throwing motor 8 is provided above the discharge port 10, and the throwing plate 9 is provided on the material throwing motor 8. The throwing plate 9 is fixedly connected to the material throwing motor 8 by setting a coupling, etc. A reducer can also be connected between the material throwing motor 8 and the throwing plate 9 to prevent the throwing plate 9 from rotating too high. A guide plate is provided in the throwing plate 9 for guiding the grain in the throwing plate 9 so that the grain can be thrown out more evenly. The throwing plate 9 is a hollow, uncovered inverted frustum-shaped metal plate. The material throwing motor 8 is used to drive the throwing plate 9 to rotate so that the throwing plate 9 throws out the dust-removed grain falling from the discharge port 10, so that the grain can fall evenly into storage bins, dryers and other devices.
[0035] Working Principle: When grain enters the upper grain duct 1 and slides downward, it bounces and slides down several louvers 3. During this descent, the grain and impurities are inevitably separated. At this point, the dust removal fan 7 activates airflow from the bottom of the upper grain duct 1, entering the gaps between the louvers 3 and driving impurities toward the dust removal fan 7. The fan then pulls these impurities upward and into the dust removal outlet 6 for discharge. The grain, due to its own weight, moves downward within the upper grain duct 1 and into the dryer. After several cycles, the grain is essentially free of impurities.
[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
