Description

Technical Field

[0001] This utility model relates to the field of occupational hazard protection, specifically to a large-size shell cleaning and ventilation workbench. Background Technology

[0002] Organic solvent cleaning processes are widely used in industries such as electronics, manufacturing, automotive, aerospace, and military, for cleaning, removing dirt, and degreasing workpiece surfaces. However, most organic solvents are mainly composed of petroleum-based compounds, ketones, alcohols, esters, alkylbenzenes, etc., which are highly volatile and flammable, posing a significant health hazard to workers.

[0003] Currently, the cleaning process for large workpieces often uses full-room exhaust ventilation to dilute toxic substances, but workers are still exposed. Some wiping processes use side-suction or top-suction hoods to remove volatile toxic substances from the workplace. However, due to the large size of the workpieces, the control range of the exhaust hoods is insufficient, resulting in poor toxic substance control. Furthermore, the breathing zone of workers is located between the pollutants and the top-suction hood, so the level of exposure to occupational hazards is not reduced. Considering that organic solvents are denser than air, it is advisable to use bottom-suction exhaust hoods for ventilation to prevent workers from contracting occupational diseases.

[0004] Currently, most organic solvent cleaning workbenches serve only as work support platforms and lack ventilation and purification systems. Traditional organic solvent cleaning workbenches are mostly designed for small workpieces, using only downward suction exhaust, and the workbench area is relatively small. However, when cleaning larger workpieces, especially those with large casings, and primarily focusing on cleaning the ends, downward exhaust only provides limited control. To achieve the desired effect, the exhaust volume needs to be increased, leading to a significant increase in energy consumption. Utility Model Content

Detailed Implementation

[0030] Example 1:

[0031] Reference Figure 1-2 This is a structural schematic diagram of Embodiment 1 of the present invention, showing a large-size shell cleaning and ventilation workbench, comprising:

[0032] Workbench 1;

[0033] Side plates 2 are detachably connected to both sides of the workbench 1;

[0034] Workbench 3, which is detachably connected to the upper surface of workbench 1;

[0035] Housing support 4, which is detachably connected to the upper surface of the workbench 1;

[0036] The exhaust system is located inside the workbench 1;

[0037] Both the workbench 3 and the side plate 2 have exhaust holes, and the exhaust parts are connected to the exhaust port of the workbench 3 and the exhaust hole of the side plate 2, respectively.

[0038] In actual use: By connecting the exhaust section to the exhaust system or negative pressure system, large workpieces are placed on the housing support 4. First, the exhaust system is started. Since the worktable 3 and side plate 2 are connected to the exhaust section, a negative pressure is generated inside the exhaust section, causing air to be drawn in through the exhaust holes on the worktable 3 and side plate 2 and then sent into the exhaust system. During the process of air being drawn in, airflow is generated, which simultaneously cleans the housing. Volatile substances are affected by the air and enter the exhaust section, preventing the volatile substances from escaping. At the same time, airflow is formed on both sides of the worktable 1 through the exhaust holes on the side plate 2, thereby increasing the capture surface of volatile gases and further reducing the escape of gases.

[0039] Example 2:

[0040] Reference Figure 1-2 The difference in this embodiment is that the workbench 1 is a rectangular frame, the workbench surface 3 and the side plate 2 are located on the inner side of the upper surface and the inner side of the side surface of the workbench 1, respectively, the exhaust part is set inside the workbench 1, and the housing support 4 is detachably connected to the upper surface of the workbench 1.

[0041] In actual use: The rectangular frame mechanism of the worktable 1 facilitates the installation of the worktable surface 3 and the side plate 2, reduces subsequent processing steps, and can be directly assembled. At the same time, the size can be increased according to different workpiece sizes to ensure that the workpiece is covered by airflow during wiping.

[0042] The workbench 1 is no less than 2.0m in length and no less than 1.5m in width, and is made of corrosion-resistant materials, including but not limited to stainless steel, aluminum alloy, and brass.

[0043] Example 3:

[0044] Reference Figure 1-2 The difference in this embodiment is that: the workbench 3 includes at least two, the upper surface of the workbench 1 is fixed with an upper crossbeam 15, both workbench surfaces 3 can be detachably connected to the inner side of the upper surface of the workbench 1, and at least two workbench surfaces 3 are connected to the exhaust section.

[0045] In actual use: In order to improve the collection effect of the workbench 3, installing a pair of workbench 3 can solve the problem of gas escape caused by the large area of ​​the workbench 3, which results in poor or no collection effect in some areas.

[0046] Example 4:

[0047] Reference Figure 1-2The difference in this embodiment is that the exhaust section includes a flow equalization box 5, an exhaust short connector 6, an exhaust duct 7, an upper exhaust hood 8, and a side exhaust hood 9. The flow equalization box 5 is installed inside the workbench 1. The top of the upper exhaust hood 8 is detachably connected to the lower surface of the workbench surface 3. The side exhaust hood 9 is detachably connected to the side of the side plate 2 located inside the workbench 1. The upper exhaust hood 8 and the side exhaust hood 9 are detachably connected to the flow equalization box 5 by the exhaust short connector 6. One end of the exhaust duct 7 is connected to the front side of the flow equalization box 5, and the other end of the exhaust duct 7 extends to the outside of the workbench 1.

[0048] In actual use: the fresh air system draws air from the flow equalization box 5 through the exhaust duct 7. The flow equalization box 5 draws air from the upper exhaust hood 8 and the side exhaust hood 9 through the exhaust short circuit 6. The air outside the workbench 1 enters through the exhaust hole, forming an airflow. The flow equalization box 5 can make the suction force in each upper exhaust hood 8 and side exhaust hood 9 the same, preventing large differential pressure and the problem of reduced collection surface.

[0049] Example 5:

[0050] Reference Figure 1-2 The difference in this embodiment is that: lower crossbeams 10 are fixed on the lower inner parts of both the front and rear sides of the workbench 1, a lower fixing plate 11 is fixed below the lower crossbeams 10 and inside the workbench 1, and movable plates 12 are detachably connected above the lower crossbeams 10 and inside the workbench 1. The bottom end of the lower fixing plate 11 located on the front side of the workbench 1 has an opening, and the exhaust pipe 7 extends through the opening to the outside of the workbench 1.

[0051] In actual use: The lower fixed plate 11 and the lower crossbeam 10 can improve the structural strength of the workbench 1, while the movable plate 12 can enclose the interior of the workbench 1, reducing contamination inside the workbench 1.

[0052] Example 6:

[0053] Reference Figure 1-2 The difference in this embodiment is that a trapezoidal plate 13 is provided on the front side of the lower fixing plate 11 located on the front side of the workbench 1, and the exhaust pipe 7 is located inside and below the trapezoidal plate 13.

[0054] In actual use: the trapezoidal plate 13 is used to prevent people from accidentally stepping on the exhaust pipe 7, which would cause the exhaust pipe 7 to deform or break. The trapezoidal plate 13 can be reinforced to improve the corresponding load-bearing structure.

[0055] Example 7:

[0056] Reference Figure 1-2The difference in this embodiment is that the housing support 4 is composed of at least one pair of support plates 14, the pair of support plates 14 are fixed on the upper surface of the workbench 1, and the top of the support plate 14 has an arc-shaped bearing groove.

[0057] In actual use: the workpiece can be placed in the bearing groove on the support plate 14, so that there is a gap between the workpiece and the worktable 3, which improves the capture effect. At the same time, a support plate 14 can be set in the middle of the worktable 1 according to the length of the workpiece to prevent the workpiece from being bent by pressure during cleaning.

[0058] In this embodiment, support plates 14 are fixed on both sides of the upper surface of the workbench 1, and a support plate 14 is also fixed on the upper surface of the upper crossbeam 15. Each support plate 14 has three arc-shaped bearing grooves equidistantly opened in the length direction. The arc-shaped bearing grooves of each support plate 14 can be matched in size according to the size of the workpiece support position, so that the axis of the workpiece with different diameters at both ends is horizontal with the workbench surface 3, thereby allowing three workpieces to be wiped.

[0059] In this embodiment, the inner diameter of the arc-shaped bearing groove is not less than 450mm.

[0060] The top of the support plate 14 can be adjusted and replaced according to the surface structure of the workpiece. For example, for a cuboid workpiece, the top of the support plate 14 can be machined with a bearing groove that fits the cuboid workpiece.

[0061] Example 8:

[0062] Reference Figure 1-2 The difference in this embodiment is that the exhaust hole is a strip hole, the exhaust hole size of the workbench 3 is no greater than 54mm×6mm and the opening rate is no greater than 10%, and the exhaust hole size of the side plate 2 is no greater than 67mm×20mm and the opening rate is no greater than 10%.

[0063] The exhaust duct 7 is a rectangular exhaust duct, and the cross-sectional dimensions of the exhaust duct 7 are not less than 600mm × 180mm.

[0064] In actual use: the strip-shaped exhaust holes on the workbench 3 and side plate 2 make it easier for air to enter and form a stable airflow trajectory, while reducing the resistance to airflow.

[0065] Meanwhile, the large-sized exhaust duct 7 helps to match the exhaust holes of the work surface 3 and the side plate 2, preventing the airflow velocity from being too low, which would affect the suction power.

[0066] In this embodiment, the non-uniformity of the exhaust air velocity of the workbench 3 and the side plate 2 is no greater than 0.25.

[0067] Example 9:

[0068] Reference Figure 1-2 The difference in this embodiment is that the upper exhaust hood 8 and the side exhaust hood 9 are umbrella-shaped exhaust hoods.

[0069] In actual use: the upper exhaust hood 8 and the side exhaust hood 9 are umbrella-shaped exhaust hoods, characterized by one end having a larger surface area than the other end, forming a constricted feature. The end with the smaller surface area is connected to the exhaust short circuit 6, thereby improving the airflow and preventing turbulence from occurring near the corners of the exhaust short circuit 6.

[0070] In this embodiment, the upper exhaust hood 8 and the side exhaust hood 9 are trapezoidal umbrella-shaped exhaust hoods, which are easy to process and are highly compatible with the rectangular upper exhaust hood 8 and side exhaust hood 9.

[0071] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention, and all such changes are within the protection scope of the technology.
