[0002] Currently, in related technologies, a certain amount of dust and impurities are generated during the material feeding process of the dryer. As a result, the dust inside the dryer is emitted into the air, causing environmental pollution.

[0003] The prior art (authorization announcement number: CN214582368U) discloses a guide plate assembly suitable for a grain dryer, including an air inlet pipe. A strip plate is longitudinally arranged inside the air inlet pipe. The upper and lower side walls of the strip plate are fixedly connected to the inner wall of the air inlet pipe. A rotating rod is rotatably mounted on the right side wall of the strip plate via a bearing. A fan is fixedly mounted on the right end of the rotating rod.

Detailed Implementation

[0025] The following are specific implementation cases and appendices. Figures 1 to 3 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0026] A dust removal and diversion device for a dryer, such as Figures 1 to 3As shown, the dust removal and diversion device for the dryer includes: a dryer body 10, a dust collection box 11, a diversion pipe 12, an installation port 13, a receiving box 14, a first filter plate 15, a flow hole 16, an exhaust port 17, a motor frame 18, a motor body 19, and exhaust blades 20; the dust collection box 11 is a hollow cavity and is installed on the side wall of the dryer body 10; one end of the diversion pipe 12 is connected to the top of the dryer body 10, and the other end of the diversion pipe 12 is connected to the top of the dust collection box 11; the installation port 13 is located on the side wall of the dust collection box 11; the receiving box 14 is a hollow cavity, passing through the installation port 13, and is fitted against the inner wall of the dust collection box 11, and... The receiving box 14 is connected to the dust collection box 11; the first filter plate 15 is provided with a plurality of first filter holes 28, the first filter plate 15 is installed in the receiving box 14, and the first filter plate 15 is inclined; at least two flow holes 16 are provided on the upper and lower sides of the receiving box 14; the exhaust port 17 is provided on the side wall of the dust collection box 11, and the exhaust port 17 is located below the mounting port 13; the motor frame 18 is installed on the side wall of the dust collection box 11, and the motor frame 18 is arranged around the outside of the exhaust port 17; the motor body 19 is provided with an output shaft, and the motor body 19 is installed on the motor frame 18; the exhaust blade 20 is connected to the output shaft of the motor body 19, and the exhaust blade 20 is opposite to the exhaust port 17.

[0027] By installing the dust collection box 11 on the side wall of the dryer body 10, connecting one end of the guide pipe 12 to the top of the dryer body 10, and connecting the other end of the guide pipe 12 to the top of the dust collection box 11, the dryer body 10 supports the dust collection box 11, so that when the material is poured into the dryer body 10, the dust and impurities generated by the material can enter the dust collection box 11 through the guide pipe 12; by setting the mounting port 13 on the side wall of the dust collection box 11, passing the receiving box 14 through the mounting port 13, so that the receiving box 14 fits against the inner wall of the dust collection box 11, and connecting the receiving box 14 to the dust collection box 11, the dust collection box 11 supports and contains the receiving box 14. By installing the first filter plate 15 inside the receiving box 14 and tilting it, the receiving box 14 supports the first filter plate 15. Multiple flow holes 16 are arranged on the upper and lower sides of the receiving box 14, allowing air to enter the receiving box 14 through the flow holes 16 on the upper side and exit through the flow holes 16 on the lower side, thus ensuring dust can flow through the first filter plate 15. By installing the motor frame 18 on the side wall of the dust collection box 11 and mounting the motor body 19 on the motor frame 18, the motor frame 18 supports the motor body 19, improving the stability of the motor body 19. By connecting the exhaust blade 20 to the output shaft of the motor body 19 and positioning the exhaust blade 20 opposite the air extraction port 17, the motor body 19 drives the exhaust blade 20 to rotate, allowing the rotating exhaust blade 20 to extract air from the receiving box 14 through the air extraction port 17, thereby creating a negative pressure inside the receiving box 14.

[0028] When the product is used, when the material is poured into the dryer body 10, the motor body 19 is started, which drives the exhaust blades 20 to rotate. This causes the exhaust blades 20 to draw air out of the container 14 through the air extraction port 17, creating a negative pressure inside the container 14. This allows the dust generated by the material to enter the container 14 through the guide pipe 12. Since the air extraction port 17 is located below the installation port 13, the dust will flow from top to bottom after entering the container 14, ensuring that the first filter plate 15 filters the dust. Because the first filter plate 15 is installed inside the container 14 and is inclined, the contact area between the first filter plate 15 and the dust is increased, thereby improving the filtration effect of the first filter plate 15.

[0029] With the above structure, by installing the dust collection box 11 on the side wall of the dryer body 10, connecting one end of the guide pipe 12 to the top of the dryer body 10, and connecting the other end of the guide pipe 12 to the top of the dust collection box 11, the dryer body 10 supports the dust collection box 11, thereby achieving communication between the dust collection box 11 and the dryer body 10; by placing the air extraction port 17 on the side wall of the dust collection box 11, connecting the exhaust blade 20 to the output shaft of the motor body 19, and making the exhaust blade 20 face the air extraction port 17, the motor body 19 can drive the exhaust blade 20 to rotate, thereby enabling the exhaust blade 20 to extract the air from the dust collection box 11, so as to create a negative pressure inside the dust collection box 11, thereby ensuring that dust flows into the dust collection box 11. By passing the receiving box 14 through the mounting port 13, the receiving box 14 is connected to the dust collection box 11, and the first filter plate 15 is installed inside the receiving box 14. At the same time, multiple flow holes 16 are arranged on the upper and lower sides of the receiving box 14 to support and contain the first filter plate 15, so that dust can flow into the receiving box 14 to ensure that the first filter plate 15 can filter the dust. Moreover, since the receiving box 14 passes through the mounting port 13 and is connected to the dust collection box 11, the receiving box 14 and the dust collection box 11 are detachably connected. This allows the receiving box 14 to be removed from the dust collection box 11 through the mounting port 13, which facilitates the replacement of the first filter plate 15 and improves the user experience of the product.
