Description

A screening and slag removal device for wet corn after drying. Technical Field

[0001] This utility model relates to the field of corn processing technology, and in particular to a screening and slag removal device for wet corn after drying. Background Technology

[0002] In the corn processing industry, drying and screening of wet corn are key steps to ensure corn quality. After drying, corn often contains impurities such as gravel, soil, and broken grains, which need to be separated by screening and screening devices (such as vibrating screens) to improve the purity and commercial value of the corn. Currently, most screening and screening devices used for drying wet corn use vibrating screens as the core screening component. Some devices usually use loaders for feeding, where the loader scoops up and lifts the dried corn and pours it into the feed hopper of the device.

[0003] During this process, a large amount of dust (including corn dust, soil particles, etc.) is generated due to the collision between corn and impurities, air disturbance, and the large amount of feed. The dust removal design of existing screening and slag removal devices is mostly focused on the air separation stage of the screening process (such as dust removal at the same time when separating light impurities by a blower). There is a lack of targeted treatment for the dust generated during the loading stage of the loader. This untreated dust will not only cause the deterioration of the air quality in the workshop and endanger the respiratory health of the operators, but may also form dust accumulation, posing safety hazards such as fire and explosion. In order to solve the above problems, this utility model proposes a screening and slag removal device for wet corn after drying. Summary of the Invention

[0022] This utility model provides a technical solution:

[0023] Please refer to Figures 1-3. A screening and slag removal device for wet corn after drying includes: a screening machine body 1. The screening machine body 1 is a prior art device, and its working principle is prior art, so it will not be described in detail. An installation plate 2 is fixedly connected to the side wall of the screening machine body 1. A connecting rod 3 is provided through the side wall of the installation plate 2. A dust treatment mechanism is provided on the side wall of the connecting rod 3. The dust treatment mechanism includes a filter cylinder 4 fixedly connected to the side wall of the connecting rod 3. A cylinder cover 6 is threadedly connected to the filter cylinder 4. A fan 7 is provided on the cylinder cover 6 (the fan 7 is connected to the controller of the screening machine body 1). A filter screen 5 is provided inside the filter cylinder 4. A slag discharge pipe 14 and an air suction pipe 8 are provided on the filter cylinder 4 and communicate with its interior. An air inlet pipe 9 is connected to the end of the air suction pipe 8 away from the filter cylinder 4. An air suction hood 10 is connected to the end of the air inlet pipe 9 away from the air suction pipe 8. The air suction hood 10 is connected to the screening machine body 1 through a connecting mechanism.

[0024] Furthermore, the connecting mechanism includes two support frames 11 disposed on the side wall of the suction hood 10. The end of the support frame 11 away from the suction hood 10 is connected to the side wall of the screening machine body 1. The two support frames 11 connect the suction hood 10 to the screening machine body 1, which can provide stable support for the suction hood 10, prevent it from shaking due to airflow or slight collision when the loader is loading, and ensure that the suction hood 10 is always aligned with the dust generation area, thereby improving the dust adsorption efficiency.

[0025] Furthermore, two connecting plates 12 are fixedly connected to the side wall of the support frame 11. The side wall of the connecting plate 12 is provided with multiple first screws, which realizes the detachable connection between the support frame 11 and the suction hood 10 and the screening machine body 1. This design facilitates the disassembly of parts during the transportation of the device, reducing the space occupied. At the same time, when the suction hood 10 or the support frame 11 is damaged, the parts can be replaced individually, reducing maintenance costs.

[0026] Furthermore, the connecting rod 3 is slidably connected to the mounting plate 2, and multiple second screws are provided through the side wall of the mounting plate 2, so that the filter cylinder 4 can be detachably connected to the main body 1 of the screening machine, which facilitates the transportation of the equipment after it leaves the factory.

[0027] Furthermore, both the suction pipe 8 and the intake pipe 9 are equipped with flanges 13 on their side walls. The two flanges 13 are connected by multiple bolts and nuts. The suction pipe 8 and the intake pipe 9 are connected by flanges 13 and bolts and nuts, which not only ensures the airtightness of the pipe connection (avoiding dust leakage), but also realizes the detachability of the two. During transportation, the suction pipe 8 and the intake pipe 9 can be separated to reduce the overall volume. During installation, they are fastened with bolts, making the connection firm and easy to operate.

[0028] Furthermore, the side wall of the suction hood 10 is provided with a warning light strip 17, and the bottom of the filter cylinder 4 is provided with a slope. The warning light strip 17 on the side wall of the suction hood 10 illuminates during operation, which can clearly indicate the position of the suction hood 10 to the loader driver, avoid the bucket from colliding with the suction hood 10, and improve operational safety. The sloped design at the bottom of the filter cylinder 4 can guide the filtered dust to gather towards the slag discharge pipe 14, reduce the dust residue in the cylinder, and improve the slag discharge efficiency.

[0029] Furthermore, multiple mounting rods 15 are fixedly connected to the lower end of the filter cylinder 4, and the lower end of the mounting rods 15 is provided with moving wheels 16, so that the filter cylinder 4 can be moved flexibly by the moving wheels 16 after being separated from the main body 1 of the screening machine, which facilitates individual transportation, maintenance or cleaning and reduces the cost of manual handling.

[0030] In practical use, the working principle of this utility model is as follows:

[0031] When the loader pours the dried corn into the feed hopper of the main body 1 of the screening machine, the blower 7 is started (the blower 7 can be synchronously controlled by the controller of the main body 1 of the screening machine). The blower 7 creates a negative pressure in the filter cylinder 4, and sucks in the dust raised during the feeding process through the suction hood 10. The dust enters the filter cylinder 4 through the air inlet pipe 9 and the suction pipe 8 in sequence, and is intercepted and filtered by the filter screen 5. The filtered clean air is discharged through the blower 7. The intercepted dust is discharged and collected through the slag discharge pipe 14 under the guidance of gravity and the inclined surface at the bottom of the filter cylinder 4.

[0032] During transportation, the device can be disassembled in the following ways: remove the bolts and nuts on the flange 13 to separate the suction pipe 8 from the inlet pipe 9; unscrew the second screw on the mounting plate 2 to slide the connecting rod 3 off the mounting plate 2, so that the filter cylinder 4 is separated from the main body 1 of the screening machine; unscrew the first screw on the connecting plate 12 to separate the support frame 11 from the main body 1 of the screening machine and the suction hood 10. After disassembly, the volume of each component is reduced, which facilitates efficient transportation.

[0033] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
