Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, and in particular to the field of cast iron dust removal, specifically referring to a rectangular environmentally friendly dust removal hood. Background Technology

[0002] In the production process of the cast iron workshop, the tilting winch unloading station is a major source of smoke and dust. Because this location requires frequent cleaning of accumulated dust and equipment maintenance, traditional fixed dust hoods are often difficult to install due to their space constraints, leading to persistent problems with fugitive emissions. This not only causes excessive dust pollution and affects the workshop's visual environment, but also poses a serious threat to the occupational health and safety of workers due to the accumulation of toxic gases such as carbon monoxide generated during the casting process. This has become a bottleneck restricting safe and environmentally friendly production in the workshop. While existing mobile dust collection devices can partially solve the obstacle avoidance problem, they suffer from low positioning accuracy, poor sealing, and cumbersome operation procedures, making it difficult to achieve a balance between dust collection efficiency and operational convenience under complex working conditions. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a rectangular environmentally friendly dust cover.

[0004] This utility model is achieved through the following technical solution: a rectangular environmentally friendly dust removal hood is provided, including a hood body, a fixed column, and a lifting plate that is vertically slidably connected to one side of the column. The hood body is connected to the air intake of the dust collector through a corrugated hose. The upper end of one side of the hood body is hinged to the lifting plate. A telescopic cylinder is hinged to the upper end of the column. The telescopic end of the telescopic cylinder is hinged to the hood body, and the distance from the hinge point to the lifting plate is less than the distance from the center of gravity of the hood to the lifting plate. An upper limit block is fixed on the column above the lifting plate.

[0005] During normal dust removal operations, the hood covers the lower end of the tilting winch, thereby sucking up and removing dust and fumes from the lower end. When cleaning of the lower end of the tilting winch is required, the telescopic cylinder retracts, causing the hood and lifting plate to move upward. The upper end of the lifting plate stops moving upward when it hits the upper limit block. The telescopic cylinder continues to retract, causing the hood to flip upward, thus avoiding the operating space below.

[0006] As an optimization, the cover has an inwardly recessed portion on the side near the lifting plate, and the lifting plate is disposed in the recessed portion. The recessed portion in this design allows for dust removal from the side of the column, achieving better dust removal results and saving space.

[0007] As an optimization, a limit bolt is threadedly connected to the side of the cover near the lifting plate. In this design, when the cover flips downwards, the limit bolt presses against the lifting plate, achieving positioning for the downward flip.

[0008] As an optimization, a reinforcing plate is attached and fixed to the side wall of the cover near the lifting platform, and the limiting bolt passes through the reinforcing plate. In this design, the reinforcing plate strengthens the cover at the location of the limiting bolt, preventing deformation.

[0009] As an optimization, a lower limit block is fixed to the column below the lifting plate. After cleaning, the telescopic cylinder extends, the cover and the lifting plate fall, and the lower end of the lifting plate stops moving downward by hitting the lower limit block, while the cover continues to flip downward.

[0010] As an optimization, the upper end of the cover on the side away from the lifting platform is connected to a corrugated flexible hose. This allows the upper surface of the cover to be closer to the column when it is flipped upwards, preventing interference from the corrugated flexible hose.

[0011] As an optimization, the column has a U-shaped cross-section in the horizontal plane. This allows the U-shaped space of the column to encompass the location of the hoist, achieving efficient use of space.

[0012] The beneficial effects of this utility model are as follows: This rectangular environmentally friendly dust hood, through its innovatively designed lifting and tilting mechanism, successfully resolves the spatial interference between the dust hood and cleaning operations. During dust removal operations, the hood precisely covers the dust-generating points, forming a negative pressure suction area to effectively control the spread of smoke and dust. When equipment cleaning is required, the telescopic cylinder drives the hood to first lift vertically and then tilt and fold, completely releasing the lower operating space and significantly improving operational safety. Its ingenious hinge point arrangement ensures smooth and effortless lifting of the hood, while the combined design of upper and lower limit blocks and limit bolts achieves precise positioning of the working position and the avoidance position. This structure not only maintains the sealing performance of a fixed dust hood but also possesses the flexibility of a movable device, enabling the dust removal system to be highly matched with the production process rhythm. While ensuring the working environment of employees, it significantly improves equipment maintenance efficiency, providing reliable equipment support for the inherently safe and environmentally friendly production in the cast iron workshop.

[0014] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0015] like Figures 1-8 As shown, this utility model discloses a rectangular environmentally friendly dust collection hood, comprising a hood body 1, a fixed column 3, and a lifting plate 4 vertically slidably connected to one side of the column 3. Figure 4 As shown, the column 3 has a U-shaped cross-section in the horizontal plane. The lifting plate 4 and the cover 1 are located on the side away from the opening, so that after the column 3 is fixed, its U-shaped space can cover the position of the hoist, thus realizing the effective use of space.

[0016] Two vertical slide rails 11 are fixedly connected to the column 3, and a slider 12 matching the slide rails 11 is fixedly connected to the lifting plate 4, thus guiding the lifting of the lifting plate 4. Furthermore, an upper limit block 5 located above the lifting plate 4 and a lower limit block 15 located below the lifting plate 4 are fixedly connected to the column 3. The upper limit block 5 and the lower limit block 15 are respectively fixed to the column 3 by bolts, thereby limiting the vertical movement of the lifting plate 4.

[0017] The cover 1 is a rectangular structure with an opening at the bottom, and one of its long sides is fitted with a pillar, and as shown... Figure 8 As shown, an inwardly recessed portion is provided in the middle of the side of the cover 1 near the lifting plate 4, and the lifting plate 4 is disposed in the recessed portion.

[0018] The upper surface of the cover 1 has chamfers on one top edge and two short edges near the lifting platform.

[0019] The upper end of the cover 1 on the side away from the lifting plate 4 is connected to the dust collector's air intake through a corrugated hose. Figure 1 The flexible hose connector 2 is used to connect to the corrugated hose.

[0020] The upper end of the cover 1, near the lifting platform 4, is hinged to the lifting platform 4, and the hinge axis is horizontally set, allowing the cover 1 to rotate up and down. Figure 1As shown, two vertical plate connecting seats 8 are fixedly connected to the side of the upper end of the lifting plate 4, and two cover connecting seats 9 are fixedly connected to the cover 1. The two cover connecting seats 9 are respectively hinged to the two vertical plate connecting seats 8, thereby realizing the hinge connection between the cover 1 and the lifting plate 4.

[0021] The upper end of the column 3 is hinged with a telescopic cylinder 6. The telescopic end of the telescopic cylinder 6 is hinged to the cover 1 and the distance from the hinge point to the lifting plate 4 is less than the distance from the center of gravity of the cover 1 to the lifting plate 4. This causes the telescopic cylinder 6 to retract, first driving the lifting plate 4 to slide upward. After the lifting plate 4 reaches its upper limit, the cover 1 flips upward.

[0022] In this embodiment, the telescopic cylinder 6 is a hydraulic cylinder or a pneumatic cylinder. In order to achieve the hinge connection between the two ends of the telescopic cylinder 6, an upper connecting seat 10 is fixedly connected to the upper end of the column 3, and a lower connecting seat 7 is fixedly connected to the upper end of the cover 1.

[0023] To limit the downward flipping of the cover 1, a limiting bolt 13 is threadedly connected to the side of the cover 1 near the lifting plate 4. A reinforcing plate 14 is attached and fixed to the side wall of the cover 1 near the lifting plate 4, and the limiting bolt 13 passes through the reinforcing plate 14.

[0024] How to use this utility model: During normal dust removal operations, the hood 1 covers the lower end of the tilting winch, thereby sucking up and removing dust and smoke from the lower end to ensure the operating environment for on-site personnel.

[0025] When cleaning of the lower end of the tilting winch is required, the telescopic cylinder 6 retracts, causing the cover 1 and the lifting plate 4 to move upwards until... Figure 6 In this state, the upper end of the lifting plate 4 rests on the upper limit block 5, thus stopping its upward movement. The telescopic cylinder 6 continues to retract, causing the cover 1 to flip upward, thereby avoiding the lower operating space.

[0026] After cleaning, the telescopic cylinder 6 extends, the cover 1 and the lifting plate 4 fall, and the lower end of the lifting plate 4 stops moving downward by hitting the lower limit block 15. The cover 1 flips downward until the limit bolt 13 hits the lifting plate 4, returning to the normal dust removal state.

[0027] Of course, the above description is not limited to the examples above.
