Description

Technical Field

[0001] The utility model relates to the technical field of air filtering equipment, in particular to a spray dust removal circulating filtering mechanism. Background Art

[0002] Grinding, or polishing, generally refers to a process that uses friction with a rough object to alter the physical properties of a material's surface, primarily to achieve a specific surface roughness. In painting, the surface of the object or coating is rubbed with a friction medium such as sandpaper, pumice, or fine stone powder. Grinding is performed throughout the entire painting process, requiring not only the rough surface, primer, or putty, but also after the topcoat. Its function is to remove burrs, loose rust, oil stains, and dust from the substrate surface, as well as coarse particles and impurities from the coating surface, resulting in a smooth surface. Smooth coating surfaces are polished to a certain degree of roughness to enhance adhesion.

[0003] During grinding, a large amount of dust is generated. If inhaled, it will harm your health. If spread into the air, it will pollute equipment and workshops, making it difficult to clean up.

[0004] To reduce harm to the human body, some existing technologies require operators to wear protective masks or respirators. While these can provide some protection, they fail to suppress dust and fundamentally address the problem of dust pollution. Others install a suction fan to directly suck some of the dust outdoors. However, these lack proper air ducting and filtration devices, resulting in poor performance. Utility Model Content

[0022] Reference Figure 1 、 Figure 2A spray dust removal circulation filtration mechanism includes a fan 1, which can be installed in multiple rows side by side as needed to increase the air volume and accelerate the flow of air. A first air outlet 2 and a second air outlet 3 connected to the first air outlet 2 are installed at the air outlet end of the fan 1. The first air outlet 2 and the second air outlet 3 are installed side by side above the grinding area. The grinding area can be a closed or non-closed space. The bottom surface of the first air outlet 2 is an air guide slope 200. The air guide slope 200 gradually extends upward from one end close to the fan 1 to the bottom surface of the second air outlet 3. The air guide slope 200 can increase the height of the grinding area to avoid the problem of grinding when the grinding area is low. , the head of the operator 11 collides with the bottom surface of the first air outlet 2, which is conducive to increasing the air flow rate. A wind baffle 4 is installed at the air outlet end of the second air outlet 3, and a downward-extending air guide duct 5 is formed between the wind baffle 4 and the air outlet end of the second air outlet 3. The air guide duct 5 is used to guide the wind blown out by the fan 1 to flow downward toward the grinding area. It also includes a spray assembly 6 and a water curtain paper 7. The spray assembly 6 includes a water pump 600 and a spray pipe 601 connected to the water pump 600. The nozzle of the spray pipe 601 is installed above the water curtain paper 7. The water curtain paper 7 is installed on the side close to the grinding area. An air inlet duct 8 is connected between the water curtain paper 7 and the air inlet end of the fan 1.

[0023] During operation, dust generated in the polishing area is driven by fan 1, along with the air, to rapidly flow toward the water curtain paper 7. Water curtain paper 7, also known as wet curtain paper, has a porous honeycomb structure. Water pump 600 draws water in and sprays it downward through spray pipe 601 onto the water curtain paper 7, forming a thin mist barrier. This mist barrier effectively blocks pollutants such as solvent vapor, liquid droplets, powder particles, and hair, thereby purifying the air. During this process, the water curtain paper 7 separates pollutants such as dust from the airflow, allowing water to come into contact with the pollutants, thereby settling them in the water, achieving a purification effect. Wastewater can then be collected in a wastewater tank. Simultaneously, heat is removed by water evaporation, achieving a cooling effect. The air filtered by the water curtain paper 7 is blown through air inlet duct 8 and fan 1 to the first air outlet duct 2. From there, it is directed downward through the second air outlet duct 3 and air guide duct 5 toward the polishing area, repeating the cycle. The present application can guide the air to circulate in a predetermined direction, prevent dust from spreading everywhere, and can also suppress and filter dust in the air, thereby protecting the health of the operator 11 and maintaining a clean working environment.

[0024] In some embodiments, the first air outlet duct 2 is a right-angled trapezoid, the second air outlet duct 3 is a rectangle, the diameter of the air inlet end of the first air outlet duct 2 is larger than the diameter of the air outlet end, and the air outlet end of the first air outlet duct 2 and the air inlet end of the second air outlet duct 3 are installed horizontally side by side. This structure can make the air blown out by the fan 1 more concentrated when passing through the second air outlet duct 3 with a smaller diameter, thereby increasing the air flow rate.

[0025] An arc-shaped water guide surface 9 is installed between the water spraying end of the spray pipe 601 and the water curtain paper 7. The arc-shaped water guide surface 9 is installed on the outer wall of the air inlet duct 8 through a fixing frame 12. A water collecting trough 13 is provided on the top of the fixing frame 12. The water spraying end of the spray pipe extends into the water collecting trough 13. The arc-shaped water guide surface 9 bulges outward, which can increase the contact area between water and air, allow more dust to contact with water, and reduce the temperature of the air. The water curtain paper 7 is a plate body. The width of the arc-shaped water guide surface 9 is greater than or equal to the width of the water curtain paper 7. The arc-shaped water guide surface 9 is used to guide the water flowing out of the water collecting trough 13 to flow evenly to the water curtain paper 7, and a water curtain can be formed in front of the water curtain paper 7. The water curtain can be used to adsorb dust in the mixed air, which can improve the air filtration effect.

[0026] In some embodiments, a grinding and polishing table 10 is placed in the grinding area for workers to perform grinding and polishing work. The grinding and polishing table 10 is close to the location of the water curtain paper 7, so that the generated dust can quickly flow to the location of the water curtain paper 7 to prevent the dust from spreading everywhere.

[0027] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. Although the embodiments of the present invention have been shown and described, ordinary technicians in this field can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and purpose of the present invention. The scope of the present invention is defined by the claims and their equivalents.
