Description

Technical Field

[0001] This utility model relates to the field of ultra-high voltage switch housing processing technology, specifically to an environmentally friendly housing surface treatment workshop. Background Technology

[0002] Large-scale power equipment often requires the use of ultra-high voltage switches. The structures of ultra-high voltage switch housings are diverse, and processing requires grinding and welding on the housing surface. These processes generate dust, welding fumes, and other particulate impurities or exhaust gases, which are detrimental to the health of workers in the workshop. Existing workshops typically only install exhaust fans on the walls for air exchange, which is ineffective in removing impurities and exhaust gases, making it inconvenient for personnel to work. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing an environmentally friendly shell surface treatment workshop.

[0004] This utility model is achieved through the following technical solution: an environmentally friendly shell surface treatment workshop, comprising a workshop body, with several workbenches arranged at intervals inside the workshop body. Guide rails are fixed to the side walls of the workshop body, extending along the arrangement direction of the workbenches. A traveling trolley is mounted on the guide rails, and an absorption hood is fixed to the traveling trolley. The absorption hood is located above the workbenches, with an absorption port at the bottom and a connecting pipe at the top. A quick connector is located at the upper end of the connecting pipe. A main air duct is fixed to the workshop body, located above the absorption hood and extending along the arrangement direction of the workbenches. One end of the main air duct is closed, and the other end is connected to a suction fan. Several connecting pipes are located at the bottom of the main air duct, each corresponding to one of the workbenches. A quick-connect plug that mates with the quick connector is located at the lower end of the connecting pipe.

[0005] This system is used during grinding or welding operations on a workbench. A trolley moves along guide rails, moving the absorption hood above different workbenches. The absorption hood connects to the main air duct via quick-connect couplings. A suction fan draws air in, creating negative pressure inside the absorption hood, thus extracting and removing dust and exhaust fumes from the workbenches above, facilitating work and protecting the health of personnel.

[0006] As an optimization, an activated carbon adsorption mesh and a catalyst filter mesh are fixedly attached inside the absorption hood, with the activated carbon adsorption mesh located below the catalyst filter mesh. This optimization uses the activated carbon adsorption mesh and the catalyst filter mesh to adsorb and filter particulate impurities in dust and exhaust gas, making the air environment inside the workshop more suitable.

[0007] As an optimization, a flow divider plate is fixedly connected inside the absorption hood. The flow divider plate is located below the activated carbon adsorption mesh, and flow divider ducts are formed between the opposite side walls of the absorption hood and the flow divider plate. This optimization divides the inner cavity of the absorption hood into two flow divider ducts by the flow divider plate. After the ducts are narrowed, the wind speed at the absorption port is increased, thereby improving the suction intensity.

[0008] As an optimization, the flow divider has a V-shaped cross-section with the tip of the V-shaped flow divider pointing downwards. The flow divider's side and the inclined sidewall of the absorption hood form the flow divider duct. This optimized V-shaped flow divider, with its side and the inclined sidewall of the absorption hood forming a small funnel-shaped flow divider duct, improves airflow intensity.

[0009] As an optimization, the lower end of the connecting pipe is fixed to the top of the absorption cover via a flow guide shroud. This optimization, through the flow guide shroud, makes the airflow smoother.

[0010] As an optimization, an electrically controlled valve is installed on the connecting pipe. This optimization facilitates the control of the opening and closing of the suction flow of each connecting pipe.

[0011] As an optimization, the upper end of the connecting pipe is connected to the bottom of the main air duct via a pipe expansion joint. This optimization reduces pipe stress and facilitates the connection of quick couplings and quick plugs.

[0012] The beneficial effects of this invention are as follows: The trolley moves along the guide rail, thereby moving the absorption hood above different workbenches. The absorption hood is connected via quick-connect couplings and corresponding quick-connect plugs. A suction fan draws air in, creating negative pressure inside the absorption hood, thus effectively sucking out dust and exhaust gases from the workbenches above them, facilitating work and protecting worker health. The sucked-out impurities are adsorbed and filtered through activated carbon and catalyst filters before being discharged as clean air, making the workshop air environment more suitable and environmentally friendly. The absorption hood can be moved to different workbenches via the trolley for suction, making it more flexible and convenient to use. Attached Figure Description

[0018] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0019] like Figures 1-3 As shown, an environmentally friendly shell surface treatment workshop includes a workshop body 1, and several workbenches 2 are arranged at intervals inside the workshop body 1. In this embodiment, the workshop body 1 is provided with two workbenches 2, which are used for grinding and welding operations respectively.

[0020] A guide rail 3 is fixedly connected to the side wall of the workshop body 1. The guide rail 3 extends along the arrangement direction of several workbenches 2. A traveling trolley 4 is movably mounted on the guide rail 3. An absorption cover 5 is fixedly connected to the traveling trolley 4 and is located above the workbenches 2. In this embodiment, the traveling trolley 4 is a 1T electric I-beam slide rail trolley, which can be directly purchased from the market. The traveling trolley 4 is moved axially along the guide rail 3 by personnel, so that the absorption cover 5 moves along the arrangement direction of several workbenches 2, thereby allowing the absorption cover 5 to be moved above different workbenches 2 for suction operations, which is convenient to use.

[0021] The bottom of the absorption hood 5 is provided with an absorption port 51, and the top of the absorption hood 5 is provided with a connecting pipe 7. A quick connector 8 is fixedly connected to the upper end of the connecting pipe 7. A main air duct 13 is fixedly connected inside the workshop body 1. The main air duct 13 is located above the absorption hood 5 and extends along the arrangement direction of several workbenches 2. One end of the main air duct 13 is closed, and the other end is connected to a suction fan 14. Several connecting pipes 10 are provided at the bottom of the main air duct 13. Each connecting pipe 10 corresponds to one of the several workbenches 2. A quick connector 9 that mates with the quick connector 8 is fixedly connected to the lower end of the connecting pipe 10.

[0022] Specifically, the suction fan 14 is installed outside the workshop body 1, and the end of the main air duct 13 extends to the outside of the workshop body 1 and is connected to the input end of the suction fan 14. The suction fan 14 draws air into the main air duct 13. By positioning the main air duct 13 above the absorption hood 5, when the absorption hood 5 moves above the workbench 2, the connecting pipe 10 at the bottom of the main air duct 13 and the connecting pipe 7 at the top of the absorption hood 5 are aligned vertically. Through the quick-connect coupling 8 and quick-connect plug 9, the absorption hood 5 is connected to the main air duct 13, thereby enabling the absorption hood to draw in dust and exhaust gas, facilitating personnel operation and protecting personnel health.

[0023] In this embodiment, the quick connector 8 is a type B lever quick-connect connector, and the quick-connect plug 9 is a flange-type quick-connect plug that is compatible with the type B lever quick-connect connector. Both can be purchased directly from the market.

[0024] In this embodiment, the upper end of the connecting pipe 10 is connected to the bottom of the main air duct 13 through the pipe expansion joint 12, which can reduce pipe stress and facilitate the docking of the quick connector 8 and the quick plug 9.

[0025] The coupling pipe 10 described in this embodiment is equipped with an electrically controlled valve 11, which facilitates the control of the opening and closing of the coupling pipe.

[0026] Specifically, an activated carbon adsorption mesh 16 and a catalyst filter mesh 15 are fixedly connected inside the absorption hood 5, with the activated carbon adsorption mesh 16 located below the catalyst filter mesh 15. The activated carbon adsorption mesh and the catalyst filter mesh adsorb and filter particulate impurities from dust and exhaust gas, making the air environment inside the workshop more suitable. The clean air is then discharged to the outside of the workshop body 1 by the exhaust fan 14, making it more environmentally friendly.

[0027] A diversion plate 17 is fixedly connected inside the absorption hood 5. The diversion plate 17 is located below the activated carbon adsorption mesh 16, and diversion channels 52 are formed between the opposite side walls of the absorption hood 5 and the diversion plate 17. The diversion plate 17 has a V-shaped cross-section, with the pointed end of the V-shaped diversion plate 17 facing downwards. The diversion channel 52 is formed between the side of the diversion plate 17 and the inclined side wall of the absorption hood 5. In this embodiment, the side of the V-shaped diversion plate and the inclined side wall of the absorption hood form a funnel-shaped diversion channel. The diversion plate divides the inner cavity of the absorption hood into two diversion channels 52, narrowing the airflow at the absorption port, thereby increasing the airflow intensity at the absorption port and enhancing the suction effect.

[0028] In this embodiment, the lower end of the connecting pipe 7 is fixedly connected to the top of the absorption cover via a flow guide 6. The flow guide 6 in this embodiment has a semi-circular structure, which facilitates smoother airflow.

[0029] Working Principle: During operation, the operator first performs grinding work on one of the workbenches 2. The operator controls the moving trolley 4 to move the absorption hood 5 above the workbench 2. The quick connector 8 of the connecting pipe 7 is connected to the quick connector 9 of the corresponding connecting pipe 10 above the workbench 2, and the solenoid valve 11 of the connecting pipe 10 is opened. At this time, the solenoid valve 11 of the connecting pipe 10 above the other workbench 2 is in the closed state. The suction fan 14 is started to draw air, creating negative pressure inside the absorption hood 5, thereby sucking away the dust generated during grinding. The dust is then adsorbed and filtered through the activated carbon adsorption mesh 16 and the catalyst filter mesh 15. After the grinding operation is completed, the solenoid valve is closed.

[0030] After the grinding operation is completed, the work is transferred to another workbench 2 for welding. Similarly, the personnel control the moving trolley 4 to move the absorption hood 5 to the top of the other workbench 2 to extract the welding fumes. After being adsorbed and filtered by the activated carbon adsorption net 16 and the catalyst filter net 15, the clean air is discharged by the suction fan 14, which is more environmentally friendly.
