[0001] This utility model relates to the field of waste gas treatment technology, specifically to a waste gas treatment device for automotive painting workshops. Background Technology

[0002] The prior art, such as the exhaust gas treatment device for a painting workshop with application number "202321378070.1", uses a drive motor to rotate the rotating rod and the reciprocating screw. Since the movable sleeve has a slider that is slidably connected to the outside of the sliding rod, the movable sleeve will drive the guide hood to move left and right, collecting exhaust gas from multiple areas, thus achieving the purpose of collecting exhaust gas from multiple areas.

[0003] However, the aforementioned technical solutions typically only support unidirectional or planar movement in their drive mechanisms, making it difficult to adapt to the needs of exhaust gas collection at different heights and positions in three-dimensional space, especially in the case of large workpieces or complex spraying scenarios, where the coverage is limited.

[0004] Therefore, a waste gas treatment device for automobile painting workshops is proposed. Utility Model Content

[0029] like Figure 1-4As shown, an exhaust gas treatment device for an automotive painting workshop includes a fan 1, a treatment box 2, and a suction box 3. The suction box 3 achieves three-dimensional spatial movement through a first driving component 5 and a second driving component 6. The first driving component 5 includes a slide rail 7 arranged along the length of the workshop, a motor 701, a lead screw 702, and a slider 703, used to drive the suction box 3 to move horizontally and longitudinally. The second driving component 6 includes a slide rail 7 arranged along the height of the workshop, a motor 701, a lead screw 702, and a slider 703, and is vertically connected to the first driving component 5, used to drive the suction box 3 to move vertically. The length of the suction box 3 matches the width of the workshop, and it is equipped with a detachable filter screen 302 inside. Specifically, the slide rail 7 in the first driving component 5 is arranged along the length of the workshop, providing a track for the suction box to move horizontally and longitudinally. The length should be determined according to the length of the workshop to ensure that the suction box 3 can move within the entire length of the workshop; the slide rail 7 in the second drive component 6 is arranged along the height direction of the workshop and is vertically connected to the first drive component 5. This vertical connection allows the suction box 3 to achieve vertical lifting and lowering on the basis of horizontal longitudinal movement, thus moving flexibly in three-dimensional space; the length of the suction box 3 matches the width of the workshop. This design allows the suction box 3 to cover the entire width of the workshop, thus effectively collecting the exhaust gas in the width direction of the workshop during horizontal longitudinal movement; the inside of the treatment box 2 contains water, and the output end of the fan 1 extends into the water. After the exhaust gas enters the treatment box 2, it can be pre-treated by the water, and then finally filtered by the activated carbon adsorption layer 201.

[0030] like Figure 4 As shown, the suction box 3 is flexibly connected to the fan 1 via a connecting pipe 4. The treatment box 2 contains an activated carbon adsorption layer 201, and the connecting pipe 4 adopts a telescopic corrugated pipe structure. Specifically, the suction box 3 is flexibly connected to the fan 1 via the connecting pipe 4. This flexible connection method can adapt to the movement of the suction box in three-dimensional space, avoiding damage or leakage of the connecting pipe due to changes in the position of the suction box. The activated carbon adsorption layer 201 inside the treatment box 2 is used to adsorb organic pollutants in the waste gas. Activated carbon has a large specific surface area and adsorption capacity, effectively removing organic matter, odors, and other pollutants from the waste gas. The activated carbon adsorption layer 201 can be installed using snap-fit ​​or bolt fixing methods to ensure its sealing after installation and facilitate subsequent periodic replacement.

[0031] like Figure 2-4As shown, limit sensors are provided at the ends of the slide rails 7 of the first driving component 5 and the second driving component 6 to ensure that the suction box 3 automatically stops when it moves to the workshop boundary. Specifically, when the suction box 3 reaches the workshop boundary, the limit sensor will send a signal to trigger the automatic stop mechanism to prevent the suction box 3 from exceeding the predetermined movement range. Through the automatic stop function of the limit sensor, the suction box 3 can be effectively prevented from colliding with the workshop wall or other equipment due to exceeding the boundary, thereby reducing the risk of equipment damage.

[0032] like Figure 4-5 As shown, the top of the suction box 3 is equipped with a fixing plate 303. The filter screen 302 is detachably connected to the fixing plate 303 by connecting bolts 304, which facilitates quick maintenance. Specifically, the filter screen 302 is connected to the fixing plate 303 by connecting bolts 304. This connection method is simple and reliable, and facilitates quick disassembly and installation. When the filter screen needs to be replaced or cleaned, the operator only needs to loosen the connecting bolts 304 to easily remove the filter screen, complete the maintenance, and then reinstall it. This detachable design greatly reduces equipment downtime and improves equipment operating efficiency.

[0033] like Figure 5 As shown, the filter screen 302 is inserted into the suction box 3 through the slot 301. The slot 301 is equipped with a sealing strip to prevent exhaust gas leakage. The slot 301 is located at the bottom of the suction box 3. Specifically, the slot 301 is located at the bottom of the suction box 3 to ensure that the filter screen 302 can be securely inserted and fixed inside the suction box. The sealing strip inside the slot 301 primarily prevents exhaust gas from leaking through the gap between the filter screen 302 and the suction box 3. The sealing strip effectively improves the sealing performance of the equipment and ensures the efficiency of exhaust gas treatment. The sealing strip should be made of high-temperature resistant and corrosion-resistant materials to withstand the harsh environment that may be encountered during the exhaust gas treatment process.

[0034] like Figure 2-4 As shown, the slider 703 is slidably disposed inside the slide rail 7, and the slider 703 is threadedly sleeved on the lead screw 702. The lead screw 702 is connected to the main shaft end of the motor 701. The slide rail 7 in the second drive component 6 is disposed at the bottom end of the slider 703 in the first drive component 5. Specifically, the operation of the motor 701 can drive the lead screw 702 to rotate, which in turn can drive the slider 703 to slide inside the slide rail 7, thereby driving the suction box 3 to move in a three-dimensional manner in the spraying workshop. The motor 701 can be connected to the controller through an encoder to realize its control.

[0035] In summary: After the fan 1 starts, it generates negative pressure, which connects the suction box 3 and the treatment box 2 through the connecting pipe 4 with a telescopic corrugated structure. The suction box 3 achieves three-dimensional movement through the first driving component 5 and the second driving component 6. The motor 701 of the first driving component 5 drives the lead screw 702 to rotate, causing the slider 703 to move longitudinally along the horizontal slide rail 7. The slide rail 7 of the second driving component 6 is vertically installed at the bottom of the slider 703, and its motor 701 drives the suction box 3 to rise and fall vertically through the lead screw 702. The length of the suction box 3 matches the width of the workshop, and the bottom of the interior is provided with a slot 301 with a sealing strip. The filter screen 302 is inserted into the slot 301 and fixed by the connecting bolts 304 of the fixing plate 303. After the exhaust gas is initially filtered by the filter screen 302 of the suction box 3, it enters the treatment box 2 through the connecting pipe 4, first undergoes water bath treatment, and then completes purification through the activated carbon adsorption layer 201. Limit sensors are provided at the ends of the slide rails 7 of the first driving component 5 and the second driving component 6. When the suction box 3 moves to the boundary, it is triggered to stop. The motor 701 is connected to the controller through the encoder to achieve precise positioning, so that the suction box 3 can move in the three-dimensional space of the workshop to collect waste gas according to the preset path.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
