Description

Technical Field

[0001] This utility model relates to the field of gas dust removal technology, specifically to a modular welding fume collection and treatment device. Background Technology

[0002] Welding sites generate fumes and iron powder particles, resulting in poor air quality that affects the health and safety of workers. Therefore, it is necessary to install dust-laden gas treatment equipment on-site to purify the gas.

[0003] Existing dust removal equipment mostly uses fans and other devices to directly draw in gas for filtration. However, iron particles and other contaminants adhere to the filter screen, making them difficult to recover. Furthermore, directly using a dust hood to draw in fumes places high demands on the fan's suction power to reduce the escape of dust-laden fumes and ensure timely treatment. However, the filtration capacity decreases under high-speed airflow conditions, affecting the treatment effect. On the other hand, traditional dust hoods have a limited adsorption range, unable to capture large areas of welding fumes, thus failing to guarantee the final fume treatment effect. Utility Model Content

[0004] Technical objective: To address the shortcomings of existing dust removal equipment, this utility model discloses a modular welding fume collection and treatment device.

[0005] Technical solution: To achieve the above technical objectives, the present invention adopts the following technical solution:

[0006] A modular welding fume collection and treatment device includes a dust collection hood and a fume treatment box. The dust collection hood is connected to the fume treatment box via a pipeline. An air suction device is connected to the outlet end of the fume treatment box. The air suction device draws gas to generate negative pressure on the surface of the dust collection hood for adsorption treatment of welding fumes. A jet pipe is set in the center of the dust collection hood. The jet pipe is connected to the air outlet end of the air suction device, and part of the treated gas is sprayed out at high speed from the jet pipe, causing the welding fumes to gather towards the dust collection hood.

[0007] Preferably, the dust collection hood of this utility model adopts a cylindrical structure, with the jet pipe concentrically installed at one end of the dust collection hood away from the fume treatment box, and an air intake hole for gas containing welding fumes to enter is opened on the outer wall of the dust collection hood.

[0008] Preferably, the dust treatment box of this utility model is provided with an electromagnetic adsorption mechanism and a filtration mechanism along the air inlet flow direction. The electromagnetic adsorption mechanism includes an electromagnetic adsorption plate with its surface parallel to the air inlet flow direction. When the gas flows through the electromagnetic adsorption plate, the iron powder particles in the gas are removed by the electromagnetic adsorption plate.

[0009] Preferably, the filtration mechanism of this utility model includes an installation frame and a filter screen that can be detachably installed on the installation frame. The installation frame is a separate double-layer structure, and the edge of the filter screen is clamped inside the installation frame.

[0010] Preferably, the dust treatment box of this utility model has a corresponding installation groove for the overall installation of the filter mechanism. The installation groove matches the installation frame, and a sliding sealing baffle is provided on the upper part of the installation groove to restrict the installation frame within the dust treatment box.

[0011] Preferably, the lower surface of the sliding sealing baffle of this utility model is slidably engaged with the dust treatment box via a guide rail, and an elastic mechanism is provided at the end of the sliding sealing baffle to push the sliding sealing baffle to reset after opening.

[0012] Beneficial effects: The modular welding fume collection and treatment device of this utility model has the following beneficial effects:

[0013] 1. The dust collection hood, fume treatment box, and air suction equipment of this utility model are set up separately, which can realize the modular assembly of the whole device.

[0014] 2. The dust collection hood of this utility model adopts a cylindrical structure. It uses a jet pipe connected to the outlet end of the suction equipment to generate a high-speed airflow in the center, which creates a negative pressure inside the dust collection hood. This allows the welding fumes on the outer periphery of the dust collection hood to enter the dust collection hood with the gas. This increases the suction area while ensuring the suction effect in each area. Compared with the method of using a fan for suction, this utility model can reduce the power requirement of the fan while ensuring the suction effect and reducing the overall energy consumption of the system.

[0015] 3. The dust treatment box of this utility model is equipped with an electromagnetic adsorption mechanism, which can adsorb iron dust particles in the gas, thereby facilitating unified collection and treatment. At the same time, it can reduce the processing pressure of the filtration mechanism and reduce the frequency of filter replacement.

[0016] 4. The filter screen of this utility model can be detachably installed in the double-layer structure installation frame, and the installation frame can be directly inserted into the installation slot to realize the assembly of the filter screen in the dust treatment box, which can quickly realize the disassembly and replacement of the filter screen.

Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and not by way of limitation. Rather, the following description provides convenient illustrations for implementing exemplary embodiments of the present disclosure. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the teachings of the present disclosure without departing from the scope or spirit of the present disclosure.

[0022] like Figure 1 and Figure 2 As shown, this utility model discloses a modular welding fume collection and treatment device, including a dust collection hood 1 and a fume treatment box 2. The dust collection hood 1 is connected to the fume treatment box 2 via a pipe 3. An air suction device 4 is connected to the outlet end of the fume treatment box 2. The air suction device 4 draws gas to generate negative pressure on the surface of the dust collection hood 1 for the adsorption and treatment of welding fumes. A jet pipe 5 is set in the center of the dust collection hood 1. The jet pipe 5 is connected to the air outlet end of the air suction device 4, and part of the treated gas is sprayed out at high speed from the jet pipe 5, causing the welding fumes to gather towards the dust collection hood 1. This utility model utilizes high-speed airflow to create negative pressure in various areas of the dust collection hood for the absorption of fume gas, thereby reducing gas dispersion and increasing the absorption area, achieving rapid absorption and treatment of welding fumes.

[0023] In the embodiments of this utility model, the processing device can be installed and fixed on the base as a whole, and the base can be driven to move to adjust the position of welding fume extraction. Furthermore, the dust extraction hood 1, the fume treatment box 2, and the air extraction device 4 of this utility model all use a flange-type detachable structure design to form a modular structure, which can flexibly replace and adjust the equipment according to the usage requirements, and also facilitates maintenance in case of failure.

[0024] The dust collection hood 1 of this utility model adopts a cylindrical structure. The jet pipe 5 is concentrically installed at one end of the dust collection hood 1 away from the fume treatment box 2. An air intake hole 6 is opened on the outer wall of the dust collection hood 1 for the gas containing welding fumes to enter. An electromagnetic adsorption mechanism 7 and a filter mechanism 8 are arranged inside the fume treatment box 2 along the air intake flow direction. The electromagnetic adsorption mechanism 7 includes an electromagnetic adsorption plate with its surface parallel to the air intake flow direction. When the gas flows through the electromagnetic adsorption plate, the iron powder particles in the gas are removed by the electromagnetic adsorption plate.

[0025] The filter mechanism 8 of this utility model includes a mounting frame 9 and a filter screen 10 detachably mounted on the mounting frame 9. The mounting frame 9 is a separate double-layer structure, and the edge of the filter screen 10 is clamped inside the mounting frame 9. To facilitate the disassembly and replacement of the filter screen 10, the dust treatment box 2 of this utility model is provided with a corresponding mounting groove 11 for the overall installation of the filter mechanism 8. The mounting groove 11 matches the mounting frame 9, and a sliding sealing baffle 12 is provided on the upper part of the mounting groove 11 to restrict the mounting frame 9 inside the dust treatment box 2.

[0026] The lower surface of the sliding sealing baffle 12 is slidably engaged with the dust treatment box 2 via a guide rail. An elastic mechanism 13 is provided at the end of the sliding sealing baffle 12 to push the sliding sealing baffle 12 to reset after opening. The elastic mechanism 13 uses a spring 14 arranged in the same direction as the guide rail. One end of the spring 14 is connected to the end of the sliding sealing baffle 12, and the other end is fixed by a fixing block 15 fixed on the dust treatment box 2.

[0027] In use, the suction device 4 provides suction power, creating a negative pressure inside the dust collection hood 1 and the fume treatment box 2 to draw in the welding fumes, allowing the external welding fumes to enter the treatment device for processing. Simultaneously, the outlet end of the suction device 4 is equipped with a branch gas outlet and a main gas outlet, with the branch gas outlet connected to the jet pipe 5. Figure 1 (The connecting pipes are not shown in the diagram). The distribution of gas volume between the branch gas outlet and the main gas outlet can be controlled by valves. Part of the gas enters the jet pipe 5 from the branch gas outlet. The jet pipe 5 adopts a conical variable diameter structure to accelerate the airflow and form a high-speed airflow that enters the dust collection hood 1. The high-speed airflow generates a pressure difference with the surrounding gas, thereby ensuring the effective absorption of welding fumes by each opening area on the dust collection hood 1, reducing dispersion and improving the treatment effect. After the welding fumes enter the fume treatment box 2 through the pipe 3, they pass through the electromagnetic adsorption mechanism 7 and the filter mechanism 8 in sequence. The electromagnetic adsorption mechanism 7 absorbs iron particle impurities, and the electromagnetic adsorption mechanism can be disconnected to allow the iron particles to separate from the electromagnetic adsorption plate for unified collection and treatment. Then, the filter mechanism 8 filters out other impurities in the gas, and finally, it is discharged through the main gas outlet, thereby ensuring the air environment at the work site and achieving efficient collection and treatment of welding fumes.

[0028] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
