Technical Field
[0001] This utility model relates to the field of VOC automatic collection technology, and in particular to an automatic VOC collection device for exterior wall paint. Background Technology
[0002] Automatic VOC collection devices for exterior wall paint are crucial equipment in the field of building environmental protection. They are primarily used to address the pollution problem of volatile organic compounds (VOCs) during the application of exterior wall coatings. With increasingly stringent environmental regulations, the construction industry has placed higher demands on VOC emission control. Traditional collection methods often employ fixed ventilation systems, which are ill-suited to the complex and ever-changing construction environment. Modern building exteriors are increasingly complex in shape, with significant variations in construction height, and different paint types exhibit varying VOC release characteristics. This necessitates collection devices with high flexibility and adaptability. Simultaneously, the dual pressures of construction efficiency and environmental requirements have driven the industry to seek smarter and more efficient VOC collection solutions that can meet environmental standards while ensuring uninterrupted construction progress.
[0003] In existing technologies, VOC collection devices typically use a fixed-installation suction hood in conjunction with a piping system. A centrifugal fan generates negative pressure to draw volatile gases into the purification unit. The purification part often employs activated carbon adsorption or catalytic oxidation technology, with activated carbon adsorption being more widely used due to its lower cost.
[0004] The main problem with existing technologies is that the replacement process of filter components is cumbersome and time-consuming. Traditional devices use bolt-fixed or clip-locked filter cartridge installation methods, which require stopping the machine to remove multiple fasteners during maintenance. This is not only complicated to operate, but also prone to loose installation due to missing parts. Under conditions of frequent filter cartridge replacement, this design seriously affects construction efficiency and increases maintenance costs. Especially in high-altitude working environments, the disassembly process poses safety hazards, causing operators to often postpone necessary filter cartridge replacements, thereby affecting the VOC collection effect and leading to the risk of exceeding emission standards. To address these issues, an automatic VOC collection device for exterior wall paint is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an automatic VOC collection device for exterior wall paint, which aims to improve the existing filter installation method of bolt fixing or snap locking. During maintenance, it is necessary to stop the machine and disassemble multiple fasteners, which is not only complicated to operate, but also prone to problems such as loose installation due to missing parts.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatic VOC collection device for exterior wall paint includes a pad, a movable component on the outer wall of the pad, a purification box fixedly connected to the top of the pad, a guide tube fixedly connected to the top of the purification box, a telescopic tube slidably connected inside the guide tube, a suction hood fixedly connected to the top of the telescopic tube, an absorption component on the top of the pad, an adsorption plate slidably connected inside the purification box, a slot opened inside the adsorption plate, a handle fixedly connected to the outer wall of the adsorption plate, and a hollow frame fixedly connected to the outer wall of the purification box, with a buckle component inside the hollow frame.
[0008] The buckle assembly includes a buckle block and a sliding post. The buckle block is slidably connected inside the hollow frame and engages with the buckle slot. One end of the sliding post is fixedly connected to the side wall of the buckle block. A limit ring is fixedly connected to the outer wall of the sliding post.

[0010] The moving component includes a push rod and a moving wheel. The bottom of the push rod is fixedly connected to the top of the pad, and the top of the moving wheel is fixedly connected to the bottom of the pad.
[0011] As a further description of the above technical solution:
[0012] The suction assembly includes a fan, the bottom of which is fixedly connected to the top of the pad, and the inside of the purification box is fixedly connected to the output end of the fan.
[0013] As a further description of the above technical solution:
[0014] The reset assembly includes a spring, one end of which is fixedly connected to the side wall of the card block, and the other end of which is fixedly connected to the inner wall of the hollow frame. The inner wall of the limiting ring is in contact with the outer wall of the hollow frame.
[0015] As a further description of the above technical solution:
[0016] The lifting and limiting assembly includes a limiting rod, which is slidably connected inside the guide tube, and one end of the guide tube engages with a groove inside the telescopic tube.
[0017] As a further description of the above technical solution:
[0018] The other end of the limiting rod is fixedly connected to a rotating plate, and the outer wall of the guide tube is fixedly connected to a fixed frame. The rotating plate is rotatably connected inside the fixed frame.

[0022] An electric telescopic rod is fixedly connected to the outer wall of the guide tube, and a fixing block is fixedly connected to the output end of the electric telescopic rod. The side wall of the fixing block is fixedly connected to the side wall of the telescopic tube.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, by pulling the handle, the adsorption plate slides inside the purification box. Then, the locking block retracts into the hollow frame under the pressure of the locking groove. The spring is compressed by the limiting ring. When the locking groove and the locking block are completely separated, the adsorption plate can be quickly pulled out. When replacing the new adsorption plate, the locking groove presses the locking block again, and the spring rebounds to push the locking block to reset and lock, thereby making the adsorption plate securely locked. This achieves the effect of quickly replacing the filter components, solves the problem of time-consuming and laborious filter replacement in traditional devices, and improves the convenience of device maintenance.
[0025] 2. In this utility model, the fixed block is moved by starting the electric telescopic rod, and then the fixed block drives the telescopic tube to slide in the guide tube. When the suction hood reaches the target height, the spring returns and pushes the rotating plate to rotate. The rotating plate drives the limiting rod to be inserted into the groove of the telescopic tube, so that the suction hood can stay at any height, thereby achieving the effect of directional collection of VOCs at different heights. This solves the problem that traditional devices cannot adapt to changing construction scenarios and improves the adaptability and collection efficiency of the device. Attached Figure Description

[0037] Working Principle: When the automatic VOC collection device for exterior wall paint is working, the VOC gas drawn into the purification chamber 5 is filtered and purified by the adsorption plate 9. When the adsorption plate 9 needs to be replaced, pull the handle 11 fixedly connected to the outer wall of the adsorption plate 9, causing the adsorption plate 9 to slide inside the purification chamber 5. The slot 10 inside the adsorption plate 9 squeezes the block 13 inside the hollow frame 12, causing the block 13 to slide inside the hollow frame 12. The sliding column 14 fixedly connected to the side wall of the block 13 moves accordingly. One end of the spring 15 sleeved on the outer wall of the sliding column 14 is fixedly connected to the side wall of the block 13, and the other end is fixedly connected to the inner wall of the hollow frame 12. The spring 15 is compressed by the limiting ring 16. When the slot 10 and the block 13 are completely separated, the adsorption plate 9 can be quickly pulled out. When replacing the new adsorption plate 9, the slot 10 squeezes the block 13 again, and the spring 15 rebounds and pushes... The moving block 13 resets, allowing it to re-engage with the slot 10, thus securing the adsorption plate 9 and completing the quick replacement of the filter components. When the height of the suction hood 8 needs to be adjusted, the electric telescopic rod 17, fixedly connected to the outer wall of the guide tube 6, is activated. The fixed block 18, fixedly connected to the output end of the electric telescopic rod 17, drives the telescopic tube 7 to slide within the guide tube 6. The suction hood 8, fixedly connected to the top of the telescopic tube 7, rises and falls accordingly. When the suction hood 8 reaches the appropriate height, one end of the spring 21 is fixedly connected to the side wall of the rotating plate 20, and the other end is fixedly connected to the outer wall of the guide tube 6. The spring 21 rebounds, causing the rotating plate 20 to rotate within the fixed frame 19. The rotating plate 20 drives the limiting rod 22 to slide, causing one end of the limiting rod 22 to engage in the internal groove of the telescopic tube 7, thus completing the limiting and fixing of the telescopic tube 7 and achieving directional collection of VOC gases at different heights.
