Description

Technical Field

[0001] This utility model relates to the field of calcium oxide production, specifically a screening device for calcium oxide production. Background Technology

[0002] Calcium oxide is an inorganic compound that can be used as a filler, analytical reagent, building material, and refractory material after processing. It is widely used in leather making, wastewater treatment, construction, and soil improvement. In the production process of calcium oxide, a screening device is needed to screen the material. Currently, most screening devices used for calcium oxide production are integrated structures, which are inconvenient to disassemble and clean the screening screen, leading to screen blockage. Therefore, a screening device for calcium oxide production is needed.

[0003] Existing patent document CN220562228U discloses a screening device for calcium oxide production, including a screening machine. A discharge pipe is located at the lower part of the screening machine, and an anti-overflow receiving mechanism is located below the discharge pipe. The anti-overflow receiving mechanism includes a receiving box, an anti-overflow compaction plate, and a lifting sleeve. The receiving box is positioned directly below the discharge pipe. This invention, through the anti-overflow receiving mechanism and the lifting mechanism, and the cooperation of the lifting sleeve and the anti-overflow compaction plate, can seal the discharge space between the discharge pipe and the receiving box, thereby reducing the amount of calcium oxide powder received by the receiving box. The problem of diffusion occurs frequently. During the continuous receiving process of the receiving box, controlling the descent of the anti-overflow compaction plate can compact the accumulated material in the receiving box to maximize material reception. However, the CN220562228U technology is inconvenient to disassemble and clean the screen regularly, causing calcium oxide particles to clog the screen, affecting the quality of calcium oxide production screening. It is also inconvenient to control the feeding of calcium oxide particles, resulting in too much or too little feeding at a time. At the same time, it is inconvenient to classify and place the screened calcium oxide. Therefore, there is an urgent need for a screening device for calcium oxide production. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a screening device for calcium oxide production, so as to solve the problems of existing screening devices for calcium oxide production that are inconvenient to disassemble and clean the screen regularly, inconvenient to control the feeding of calcium oxide particles, and inconvenient to classify and place the screened calcium oxide.

[0015] 1. This utility model, through the setting of a nut, baffle, limiting plate, screening plate, fine screen and coarse screen, allows the nut to be disassembled and the limiting plate to be released by rotating the nut. Pulling the baffle allows it to be flipped open and the screening plate to be pulled outward, which facilitates the regular disassembly and cleaning of the screening plate, prevents the fine screen and coarse screen from becoming clogged, and improves the screening quality of calcium oxide production.

[0016] 2. This utility model, through the setting of an electric telescopic rod, toothed plate, guide plate, rotating shaft, gear and baffle plate, allows the toothed plate to slide along the guide plate by activating the electric telescopic rod, causing the gear to rotate and drive the baffle plate fixedly connected to the outer wall of the rotating shaft to flip, so that the calcium oxide particles are fed out.

[0017] 3. This utility model, through the setting of a screening plate, a fine screen, a coarse screen, a first guide plate, a second guide plate, a first collection box, and a second collection box, allows calcium oxide particles to fall onto the screening plate. Fine calcium oxide particles pass through the fine screen and fall into the second collection box through the second guide plate for collection, while larger calcium oxide particles pass through the coarse screen and fall into the first collection box through the first guide plate for collection. This facilitates the classification and placement of the screened calcium oxide particles. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Please see Figure 1-4A screening device for calcium oxide production includes a screening box 1. A threaded column 2 is fixedly connected to one side of the screening box 1. A nut 3 is movably connected to the outer wall of the threaded column 2. A clamping plate 4 is fixedly connected to the inner wall of the screening box 1. A rotating rod 5 is movably connected to the outer wall of the screening box 1. A baffle 6 is fixedly connected to the outer wall of the rotating rod 5. A limiting plate 7 is fixedly connected to the outer wall of the baffle 6. A screening plate 8 is installed inside the screening box 1. A fine screen 9 and a coarse screen 10 are fixedly connected inside the screening plate 8. The threaded column 2 is threadedly connected to the nut 3 and movably connected to the limiting plate 7. The baffle 6 forms a rotating structure with the screening box 1 through the rotating rod 5. The screening plate 8 has a slotted design and is engaged with the screening box 1 through the clamping plate 4. The clamping plate 4 is symmetrically arranged with respect to the central axis of the screening box 1, which facilitates the disassembly and cleaning of the screening plate 8 and prevents the fine screen 9 and the coarse screen 10 from becoming clogged.

[0026] Please see Figure 1-4 A screening device for calcium oxide production includes a hopper 11 fixedly connected to the top of a screening box 1. An electric telescopic rod 12 is installed on the outer wall of the hopper 11. A toothed plate 13 is fixedly connected to the output end of the electric telescopic rod 12. A guide plate 14 is fixedly connected to the outer wall of the hopper 11. A rotating shaft 15 is movably connected inside the hopper 11. A gear 16 is fixedly connected to the outer wall of the rotating shaft 15. A baffle plate 17 is fixedly connected to the outer wall of the rotating shaft 15. The toothed plate 13 and the guide plate 14 form a sliding structure, and the toothed plate 13 is meshed with the gear 16. The gear 16 and the hopper 11 form a rotating structure through the rotating shaft 15, and the baffle plate 17 and the hopper 11 form a rotating structure through the rotating shaft 15. This device facilitates controlled feeding of calcium oxide particles and prevents excessive accumulation of particles on the screening plate 8 during a single feeding.

[0027] Please see Figure 1-4 A screening device for calcium oxide production includes a first guide plate 18 fixedly connected to the inner wall of a screening box 1, a second guide plate 19 fixedly connected to the inner wall of the screening box 1, a first collection box 20 movably connected inside the screening box 1, and a second collection box 21 movably connected inside the screening box 1. The first collection box 20 and the screening box 1 form a sliding structure, and the second collection box 21 and the screening box 1 also form a sliding structure, which facilitates the classification and placement of the screened calcium oxide particles.

[0028] Working principle: In use, by activating the electric telescopic rod 12, the toothed plate 13 can slide along the guide plate 14. Since the toothed plate 13 is meshed with the gear 16, the gear 16 can rotate, causing the baffle plate 17 fixedly connected to the outer wall of the rotating shaft 15 to flip, so that the calcium oxide particles are fed out. When the calcium oxide particles fall onto the screening plate 8, the fine calcium oxide particles will pass through the fine screen 9 and fall into the second collection box 21 through the second guide plate 19 for collection, while the larger calcium oxide particles will pass through the coarse screen 10 and fall into the first collection box 20 through the first guide plate 18 for collection. By rotating the nut 3, since the nut 3 is threadedly connected to the threaded post 2, the nut 3 can be disassembled and the limiting plate 7 can be released. Pulling the baffle 6 to flip it open, and pulling the screening plate 8 outward, the screening plate 8 can slide out along the clamping plate 4, so that the screening plate 8 can be disassembled. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
