Technical Field
[0001] This utility model relates to the field of paint mist purification technology, and in particular to a high-efficiency dry purification device for coating paint mist. Background Technology
[0002] A spray booth is a specialized painting booth for spraying liquid coatings. It is one of the key pieces of equipment in an industrial painting workshop. A large amount of paint mist is generated in the spray booth, containing sticky substances, dust particles, and other harmful materials. This mist cannot be directly discharged and must undergo purification treatment. Existing paint mist purification methods include wet paint mist purification devices, dry paint mist purification devices, and electrostatic paint mist purification devices. The significance of paint mist purification machines is to achieve both internal and external environmental protection, protecting the physical and mental health of operators and reducing pollution. Paint mist purification machines are an essential piece of equipment in the spray painting production line process. When purifying paint mist, a high-efficiency dry paint mist purification device is required.
[0003] To address this, patent publication CN209866473U discloses a dry paint mist purification device, comprising a spray booth and a purification chamber. The purification chamber is divided into a first and a second interconnected section by a partition. The first section contains several paint filter papers, each with a pneumatic vibrator connected to its top. The second section contains several dust collectors and includes a pulse jet blower and a Venturi pulse jet pipe connected to the pulse jet blower. This dry paint mist purification device allows paint mist-laden air to pass sequentially through the paint filter papers, dust collectors, and purifiers for filtration and purification. The purification effect is good and efficient. The pneumatic vibrators cause the paint filter papers to vibrate, shaking off paint dust. The pulse jet blower, through the Venturi pulse jet pipe, blows air back into the dust collectors, quickly removing paint dust. This achieves automatic cleaning and prevents clogging, allowing the purification device to be reused without frequent replacement, thus saving costs.
[0004] Current high-efficiency dry purification devices for paint mist can basically meet people's needs, but some problems still exist, as detailed below:
[0005] 1. The problem of the high-efficiency dry purification device for paint mist is that it is difficult to enhance the filtration effect. When filtering paint mist, the filtration effect is not good enough, the filtration speed is not strong enough, and the working efficiency of the device is difficult to improve.
[0006] 2. The high-efficiency dry purification device for paint mist is difficult to prevent the cover from falling off. During use, the cover may fall off, which will affect the filtration of paint mist. Utility Model Content

The servo motor is installed at the bottom of the outer shell.
[0012] In use, the filter screen and the base plate first form a snap-fit structure. The filter screen can be inserted into the inside of the housing through the inlet and fixed by snapping onto the base plate. At the same time, the positioning block on the filter screen can be snapped onto the top of the fixing block. This allows the filter screen to be installed. When the filter screen needs to be replaced, the handle can be grabbed to replace the filter screen. The cover can be opened to fill the inside of the housing with paint mist. The paint mist can be filtered through the filter screen, and the filtered paint mist can be discharged through the outlet. The outlet can be opened and closed by the valve.
[0013] Furthermore, the bottom end of the filter screen is provided with a locking block, and the top end of the base plate is provided with a locking groove. The filter screen and the base plate form a locking structure, which facilitates disassembly.
[0014] Furthermore, the mounting screws and the support legs form a threaded connection, and the mounting screws are arranged in a ring shape, allowing the support legs to be installed.
[0015] Furthermore, a stirring shaft is movably connected to the top of the servo motor, and connecting rods are installed on both sides of the stirring shaft. A scraper is installed on one side of the connecting rod, and a rotating block is installed at the top of the stirring shaft. The rotation of the stirring shaft will drive the rotating block to rotate, and the rotation of the rotating block will drive the centrifugal fan blade to rotate.

[0017] Furthermore, the outer side wall of the valve is uniformly provided with external threads, and the inner side wall of the outlet is uniformly provided with internal threads that cooperate with the external threads. The valve and the outlet are connected by threads, and the outlet can be opened and closed by the valve.
[0018] Furthermore, the disassembly and assembly structure includes a fixing plate, a rotating shaft, a buckle, and a pressure plate. The fixing plate is installed at the top of the outer side of the entrance. The rotating shaft is movably connected to the inner side of the fixing plate, and a buckle is installed at the top of the rotating shaft. The rotation of the rotating shaft will drive the buckle to rotate. The buckle can lock the cover and prevent the cover from falling off.
[0019] Furthermore, a pressure plate is installed at the top of the buckle, and the pressure plate is symmetrically distributed about the central axis of the inlet, so that the buckle can be rotated by the pressure plate.
[0020] Furthermore, the positioning structure includes a positioning block, a fixing block, and a gripper. The fixing block is installed at the top inside the inlet, and the top of the fixing block is movably connected to the positioning block. The top of the positioning block is also equipped with a gripper, and the positioning block on the filter screen can be locked onto the top of the fixing block.

[0022] A servo motor is installed at the bottom of the casing. The servo motor drives the stirring shaft to rotate, which in turn drives the rotating block to rotate. The rotating block then drives the centrifugal fan blades to rotate, generating centrifugal force that causes the paint mist to rotate. Due to the centrifugal force, the paint mist repeatedly passes through the filter screen, thus enhancing the filtration effect. The rotation of the stirring shaft also drives the connecting rod to rotate, which in turn drives the scraper to rotate. The scraper cleans the filter screen and prevents it from becoming clogged. This achieves the purpose of a high-efficiency dry purification device for coating paint mist, which enhances the filtration effect.
[0023] A cover is movably connected to the top of the inlet. The cover can be inserted into the inlet. The rotating shaft on the inside of the fixing plate can rotate. The rotation of the rotating shaft will drive the buckle to rotate. The buckle can lock the cover and prevent the cover from falling off. When the cover needs to be removed, the pressure plate can be pressed to drive the buckle to rotate, so that the buckle can no longer lock the cover, and the cover can be removed. This achieves the purpose of making the cover easy to fix in the high-efficiency dry purification device for paint mist. Attached Figure Description
