Description

Technical Field

[0001] This utility model relates to the field of corn processing technology, and in particular to a cylindrical cleaning screen for drying wet corn. Background Technology

[0002] In the corn processing industry, wet corn, due to its high moisture content, needs to be dried to prevent mold growth. Screening and impurity removal before drying is a key step to ensure subsequent drying efficiency and corn quality. Screening can remove impurities such as soil lumps, gravel, and straw fragments mixed in with wet corn, reducing wear and tear on drying equipment and affecting the purity of the finished corn.

[0003] Cylindrical cleaning screens are commonly used screening equipment before drying wet corn. Their core principle is that the rotation of the cylindrical screen causes the corn to roll inside, allowing impurities smaller than the screen holes to pass through and be discharged, thus achieving separation. However, traditional cylindrical cleaning screens have significant drawbacks: wet corn, due to its moisture content, easily sticks together, and the impurities may contain sticky mud, which easily clogs the screen's mesh. Clogged mesh leads to a sharp drop in screening efficiency, requiring frequent shutdowns and disassembly for cleaning. This not only increases the labor intensity of operators but also interrupts the production process, reducing overall processing efficiency. Furthermore, frequent disassembly may exacerbate wear and tear on equipment components, increasing maintenance costs. To address these issues, this invention proposes a cylindrical cleaning screen for drying wet corn. Utility Model Content

[0025] This utility model provides a technical solution:

[0026] Please see Figures 1-6 A cylindrical cleaning screen for drying wet corn includes: an installation cylinder 1 and an installation base 18. Notably, the installation cylinder 1 is inclined and has four support legs at its lower end. A slag discharge shell 2 is connected to the side wall of the installation cylinder 1. An opening is opened at the lower end of the installation cylinder 1, and the slag discharge shell 2 is positioned directly opposite the opening and is connected to the opening to discharge the screened impurities. A cylindrical screen 3 is installed inside the installation cylinder 1 through two installation rings 4. The installation rings 4 are fixedly connected to the installation cylinder 1 and rotatably connected to the cylindrical screen 3, which ensures the stability of the cylindrical screen 3 during rotation, reduces friction loss, and extends the service life of the equipment.

[0027] Both ends of the mounting cylinder 1 are provided with cylinder covers 5 (threaded connection or multiple bolt connection). The two cylinder covers 5 are respectively connected to the feed pipe 6 and the discharge pipe. The feed pipe 6 has a feed hopper 9 on its side wall. The inner wall of the mounting cylinder 1 is fixedly connected with a retaining ring 7. The inner wall of the mounting cylinder 1 is mounted with a first motor 10 through the mounting assembly. The output shaft of the first motor 10 and the side wall of the cylindrical screen 3 are respectively provided with a gear 12 and a gear ring 11. The teeth of the gear 12 and the gear ring 11 and the details of their meshing are not shown in the figure. In fact, the two mesh with each other.

[0028] The installation cylinder 1 is equipped with a cleaning mechanism for cleaning the cylindrical screen 3. The cleaning mechanism includes a movable block 8 that is slidably connected to the inner wall of the installation cylinder 1. The lower end of the movable block 8 is fixedly connected to an air storage box 13. The air storage box 13 is equipped with multiple high-pressure nozzles 15 and a corrugated air inlet pipe 16 that communicate with its interior.

[0029] Two mounting rings 4 are equipped with drive mechanisms for moving the gas storage box 13. The drive mechanism includes a reciprocating screw 14 rotatably connected to the two mounting rings 4. The reciprocating screw 14 is threadedly connected to the moving block 8. A second motor 17 is fixedly connected to the side wall of one of the mounting rings 4. The reciprocating screw 14 is fixedly connected to the output shaft of the second motor 17 (since the moving block 8 is slidably connected to the mounting cylinder 1, the rotational motion of the reciprocating screw 14 can be converted into the axial linear motion of the moving block 8).

[0030] In this utility model, both the feed hopper 9 and the feed pipe 6 are provided with flanges on their side walls. The two flanges are connected by multiple bolts and nuts. The feed hopper 9 is provided with a sealing cover 19, which allows the feed hopper 9 to be detachably connected to the mounting cylinder 1, making it convenient for the equipment to be disassembled and transported after leaving the factory.

[0031] In this utility model, a third motor 22 is fixedly connected to the upper end of the mounting base 18, and a drive shaft 21 is fixedly connected to the output shaft of the third motor 22. Multiple stirring plates 23 are fixedly connected to the side wall of the drive shaft 21. The multiple stirring plates 23 can stir the corn in the feed hopper 9 to avoid the "bridging" phenomenon caused by the sticky clumps of wet corn (i.e., corn blocking the feed inlet) and ensure smooth feeding.

[0032] In this invention, a mounting plate is rotatably connected to the upper end of the drive shaft 21, and multiple connecting rods 25 are fixedly connected to the side wall of the mounting plate. The connecting rods 25 are fixedly connected to the feed hopper 9. The upper end of the drive shaft 21 is connected to the feed hopper 9 through the mounting plate and the connecting rods 25. The mounting plate has a triangular cross section, which reduces weight and improves structural stability, preventing the drive shaft 21 from shaking when rotating.

[0033] In this utility model, a scraper 24 is fixedly connected to the side wall of the drive shaft 21. The cross section of the mounting plate is triangular. The scraper 24 can scrape off the corn stuck to the inner wall of the feed hopper 9, reducing raw material waste. The air vent and the air mesh 20 of the mounting cylinder 1 can balance the air pressure inside the cylinder, avoid the air flow being blocked during the screening process and affect the movement of corn, and at the same time prevent impurities from overflowing from the air vent.

[0034] In the initial state, a controller is provided on the side wall of one of the support legs of the mounting cylinder 1.

[0035] In practical use, the working principle of this utility model is as follows:

[0036] Start the first motor 10, and the gear 12 drives the gear ring 11 to rotate, so that the cylindrical screen 3 rotates inside the mounting cylinder 1; wet corn is poured in from the feed hopper 9 and enters the cylindrical screen 3 through the feed pipe 6. As the cylindrical screen 3 rotates and moves, impurities smaller than the mesh size fall into the bottom of the mounting cylinder 1 through the mesh and are discharged through the slag discharge shell 2. The screened corn is discharged from the discharge pipe.

[0037] At the same time, the external air compressor supplies air to the air storage box 13 through the corrugated air inlet pipe 16. High-pressure gas is sprayed out from multiple high-pressure nozzles 15 and directly hits the mesh of the cylindrical screen 3 to flush out the blocked impurities or corn kernels. The second motor 17 is started, and the reciprocating screw 14 rotates, driving the threaded moving block 8 to slide along the inner wall of the mounting cylinder 1, so that the air storage box 13 and the high-pressure nozzles 15 reciprocate, thoroughly cleaning the entire screen surface of the cylindrical screen 3 and ensuring that the mesh is unobstructed.

[0038] During the feeding process, the third motor 22 is started, and the drive shaft 21 drives the stirring plate 23 and scraper 24 to rotate. The stirring plate 23 breaks up the corn clumps in the feed hopper 9 to prevent "bridging". The scraper 24 scrapes off the corn stuck to the hopper wall to ensure that the raw materials enter the feed pipe 6 smoothly and improve the feeding efficiency.

[0039] 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.
