Description

TECHNICAL FIELD

[0001] The utility model relates to dust protection technical field especially relates to a dust protection device for waterborne epoxy zinc base paint production. BACKGROUND

[0002] As the core component of heavy-duty coating system, waterborne epoxy zinc base paint is widely used in the protection of metal substrates in the fields of ships, bridges, petrochemical equipment, etc. Its production process involves key processes such as zinc powder dispersion, epoxy resin emulsification, and additive compounding. In industrial production, high-concentration metal dust and organic volatile compounds (VOCs) are easily produced in the process of zinc powder grinding and base paint plate surface treatment. Traditional dust control often uses a negative pressure dust collection system combined with a sealed operation box to achieve gas-solid separation through filter cartridge classification. With the tightening of environmental regulations on particulate matter concentration (PM10 / PM2.5) in the working environment and the improvement of zinc powder particle size distribution control accuracy (D50 needs to be maintained at 8-12 μm), existing protection devices need to simultaneously address the contradictory needs of dust escape suppression, online cleaning efficiency, and equipment adaptability. Especially in continuous production lines, traditional equipment lacks dynamic sealing adjustment mechanisms and dust directional collection functions, which can easily lead to uneven zinc powder settlement, equipment internal wall fouling, and secondary dusting risks.

[0003] The existing dust protection technology has the following problems: the conventional sealed operation box uses a fixed cavity structure, which cannot adjust the gap between the polishing roller and the plate according to the thickness of the base paint plate, leading to the formation of escape vortexes in the edge area due to air flow disturbance, the negative pressure dust collection port is usually fixed at the top of the box, making it difficult to cover the dust diffusion path simultaneously with the movement of the polishing station, the capture efficiency of large particle size zinc powder is insufficient, the traditional covering device relies on static sealing strips, which can easily produce micro-gaps due to mechanical vibration during the reciprocating motion of the transmission patch, causing local dust leakage, dust cleaning requires manual disassembly of the filter cartridge after stopping the machine, and there is a lack of integrated design for online brushing and directional discharge, which affects the continuous production rhythm. Therefore, we provide a dust protection device for waterborne epoxy zinc base paint production. UTILITY MODEL CONTENTS

[0028] In this embodiment, when using this dust protection device to sand and protect the primer, the worker can place the primer plate to be sanded on the operating box 12. Then, the worker can rotate the adjusting plate 14 to drive the lifting plate 15 to move up and down in the operating box 12. After adjusting to the appropriate position, stop rotating. Then, the worker can use the transmission plate 16 to transport the primer plate to the sanding roller 17 for sanding. The cover plate 21 on the operating box 12 can protect against sanding dust through the side plate shielding plate 22. At the same time, the worker can use the rotating roller 23 to brush the sanding brush 24 onto the primer plate and store it in the operating box 12. Then, the dust in the operating box 12 is discharged through the discharge pipe 13, thereby improving its practicality in actual process. Example

[0029] like Figures 1-4 As shown, protective mechanisms 3 are provided on both sides of the control box 12. The protective mechanism 3 includes a telescopic buckle 31. One end of the telescopic buckle 31 is provided with a transmission tooth buckle plate 32. A hinge 33 is provided on the bottom side of one end of the transmission tooth buckle plate 32. Transmission rollers 34 are provided at both ends of the transmission tooth buckle plate 32.

[0030] The two ends of the telescopic rod 31 are respectively connected between the control box 12 and the transmission toothed plate 32, the two sides of the hinge 33 are respectively engaged between the transmission toothed plate 32 and the control box 12, and the outer surface of the transmission roller 34 is nested between the two ends of the transmission toothed plate 32.

[0031] In this embodiment, to further enhance its practicality in actual use, corresponding protective mechanisms 3 are provided on both sides of the operating box 12. The operator can use the telescopic buckle 31 to connect to both sides of the operating box 12. The end of the telescopic buckle 31 away from the operating box 12 is connected to the transmission tooth buckle plate 32, and the bottom end of the transmission tooth buckle plate 32 near the operating box 12 can be connected by the hinge 33. The transmission roller 34 in the transmission tooth buckle plate 32 can transport the primer plate to the operating box 12 for polishing, thus making it more convenient for the operator to operate.

[0032] Working principle:

[0033] like Figures 1-4 As shown, when using this dust protection device to sand and protect the primer, the operator first places the primer plate to be treated in the operating box 12. Then, the operator can rotate the adjusting disc 14 to drive the lifting plate 15 to adjust the primer plate to a suitable height. After adjusting to the ideal position, the operator stops rotating the adjusting disc 14, allowing the primer plate to stabilize in the predetermined position within the operating box 12. Next, the operator activates the conveyor plate 16, allowing the primer plate to be moved along the conveyor path and precisely delivered to the sanding roller 17 for sanding.

[0034] To effectively protect against dust generated during the grinding process, the top of the control box 12 is equipped with a cover plate 21, and the sides are fitted with side panel shields 22, forming a comprehensive protective barrier. These designs effectively prevent grinding dust from leaking out, ensuring a clean operating environment and protecting the health of the staff.

[0035] During the polishing process, the operator can activate the rotating roller 23 to make the polishing brush 24 rotate, promptly removing dust from the surface of the primer plate and collecting it inside the control box 12. At this time, the operator can discharge the dust from the control box 12 through the discharge pipe 13, maintaining the cleanliness of the operating area and improving the safety and efficiency of the operation. This design ensures the efficient operation of the entire dust protection system, thereby effectively improving the actual performance of the device.

[0036] To further enhance the functionality of the device during actual operation, protective mechanisms 3 are installed on both sides of the control box 12. Operators connect the protective facilities on both sides of the control box 12 using telescopic rods 31, with the distal end of the telescopic rods 31 connected to the transmission toothed plate 32. The bottom of the transmission toothed plate 32 is connected to the control box 12 via hinges 33, allowing for flexible adjustment. After activation, the transmission rollers 34 inside the transmission toothed plate 32 stably transport the primer board into the control box 12 for polishing, thereby simplifying the operation process, improving the conveying efficiency of the primer board, and reducing the operator's workload.
