Description

Technical Field

[0001] This invention belongs to the field of industrial coating technology, specifically relating to a water-based paint mist separation device. Background Technology

[0002] In recent years, water-based paints have become the mainstay of the coatings industry due to their more environmentally friendly ingredients. The biggest advantage of water-based paints compared to solvent-based paints is that VOC emissions are greatly reduced. Compared to solvent-based paints, water-based paints have advantages such as less environmental pollution, high leveling properties, and good appearance. However, water-based paints also have disadvantages such as high application requirements, good conductivity, and high corrosivity.

[0003] During the paint spraying process in the spraying workshop, the paint mist contains a large amount of paint particles, and the directly emitted air still contains a certain amount of paint mist. This not only fails to meet the requirements for air circulation, but also poses a significant safety hazard. Traditional dry technology can only be applied in small-batch, intermittent spraying operations, and it is difficult to use in large-scale continuous industrial production. Summary of the Invention

Detailed Implementation

[0027] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Please see Figures 1-6According to one embodiment of the present invention, a water-based paint mist separation device includes a frame component 1, which includes a main housing 101, a main partition 102, a secondary partition 103, and a guide port 104. A plurality of main partitions 102 and secondary partitions 103 are arranged in an array inside the main housing 101, with the main partitions 102 and secondary partitions 103 spaced apart. A plurality of guide ports 104 are arranged in an array on the main partitions 102. An adsorption assembly 2 includes a rotary drum 201, an adsorption tube 202, an overflow hole 203, and a driven gear shaft 204. The rotary drum 201 is rotatably mounted in the guide port 104, and two rows of adsorption tubes 202 are arrayed on the surface of the rotary drum 201. Overflow holes 203 are provided on the adsorption tubes 202. A driven gear shaft 204 is mounted at the end of the rotary drum 201. The transmission component 3 includes a transmission rack 301, an abutment part 303, and an abutment wheel 304. The transmission rack 301 is slidably mounted on one side of the main housing 101 and meshes with the driven gear shaft 204. One end of the transmission rack 301 is fixedly connected to the abutment part 303. The abutting part 303 is movably connected to the abutting wheel 304, which drives the abutting part 303 to reciprocate on one side of the main housing 101. The abutting wheel 304 is connected to the drive motor assembly 6. The brushing mechanism 4 includes a cleaning brush rod 401, a transmission gear 402, and a transmission belt 403. The cleaning brush rod 401 is rotatably mounted in the guide port 104 and one end of it is connected to the transmission gear 402. Several transmission gears 402 are connected to each other through the transmission belt 403, and one end of the transmission belt 403 is connected to the drive motor assembly 6. The system includes: a connection between the main partition 102 and the secondary partition 103; an air extraction device 5, which is disposed on one side of the end of a plurality of main partitions 102 and secondary partitions 103 for extracting air from the main partitions 102 and secondary partitions 103; and a sealing component 7, which includes an elastic sheet 701 and a magnetic ball 702. The elastic sheet 701 is fixedly assembled at one end of the main partition 102 and the secondary partition 103, and the magnetic ball 702 is assembled inside the elastic sheet 701. The magnetic ball 702 is used to magnetically attract the two sets of elastic sheets 701 to adhere together, thereby sealing the cavity between the main partition 102 and the secondary partition 103.

[0029] In practical application, when separating water-based paint mist using this device, during the water-based paint spraying process, the end of the device containing the sealing component 7 faces the spraying surface. An air pump 5, located at one end of the main housing 101, continuously draws air between the main partition 102 and the secondary partition 103, creating a negative pressure suction state between them. This draws the paint mist ejected during spraying into the space between the main partition 102 and the secondary partition 103. Once the paint mist enters this space, several guide ports 104 are arranged on the main partition 102, and a rotating cylinder 201 is rotatably installed within each guide port 104. The surface of the rotating cylinder 201 is arrayed with two rows of... When a row of adsorption tubes 202 on the rotating drum 201 rotates to the space between the main partition 102 and the secondary partition 103, the overflow hole 203 on them is connected to the rotating drum 201, and the water entering the rotating drum 201 can flow out from the overflow hole 203 and flow to cover the surface of the adsorption tubes 202. When the paint mist moves between the main partition 102 and the secondary partition 103, the paint mist can contact the surface of the adsorption tubes 202 as it passes through the gaps in the adsorption tubes 202, and is continuously washed by water when it is adsorbed on the surface of the adsorption tubes 202. At the same time, when several rotating drums 201 are engaged with the transmission rack 301 through the driven gear shaft 204 on one side, the transmission rack 301 moves forward under the driving action of the abutment wheel 304. The rotary drum 201 reciprocates periodically, causing the adsorption tube 202, which adsorbs paint mist, to rotate to the side of the guide port 104. There, it comes into contact with the cleaning brush rod 401 mounted in the guide port 104. Driven by the transmission gear 402 and transmission belt 403 on one side, the cleaning brush rod 401 rotates continuously, sweeping away the paint mist from the surface of the adsorption tube 202. Simultaneously, the water washes away the paint mist, causing the water containing the adsorbed paint mist to drip through the guide port 104 onto the secondary partition 103 and flow out along it. At the same time, several elastic sheets 701 mounted on one side of the main partition 102 and the secondary partition 103, with magnetic balls 702 at their ends, are magnetically activated, causing the elastic sheets to... After overcoming the elastic force, the magnetic balls 702 at the ends of the insert plate 701 are attracted together, thereby sealing part of the cavity between the main partition 102 and the secondary partition 103, while opening the cavities on the adjacent sides. As the insert plate 703 moves towards the two sets of attracted magnetic balls 702, it can separate the magnetic balls 702. When the elastic force of the elastic sheet 701 is greater than the magnetic attraction force, the elastic sheets 701 on both sides separate, and under the elastic force, the elastic sheet 701 moves inertially towards the adjacent elastic sheet 701 on the other side, and is attracted to the other elastic sheet 701 by the magnetic balls 702. This achieves alternating sealing of several elastic sheets 701 on one side of the main partition 102 and the secondary partition 103, in conjunction with the periodic rotation of the rotary drum 201.When the adsorption tube 202 between the main partition 102 and the secondary partition 103 is rotated to a position perpendicular to the direction of paint mist movement, the two sets of elastic plates 701 located at one end of the main partition 102 and the secondary partition 103 are in an open state, while the adjacent side cavities are in a closed state. The adsorption tube 202 inside these cavities is in contact with the cleaning brush rod 401 for cleaning. At this time, due to the reduced number of open cavities, the negative pressure suction effect of the vacuum pump 5 on one side of the main partition 102 and the secondary partition 103 is enhanced, facilitating rapid suction of the paint mist for treatment.

[0030] Please see Figure 2 In a preferred embodiment of the invention, the secondary partition 103 is arranged at an angle.

[0031] In practical application, since the secondary baffle 103 is arranged at an angle, the water discharged from one side of the main baffle 102 drips onto the secondary baffle 103 through the guide port 104, and then flows along the secondary baffle 103 and collects, which facilitates subsequent recycling and reprocessing.

[0032] Please see Figure 2 and Figure 6 In a preferred embodiment of the invention, the two sets of adsorption tubes 202 are assembled at 90° on the rotary drum 201, and the two sets of adsorption tubes 202 are arranged facing the side of the paint mist flow direction.

[0033] In practical application, since the two sets of adsorption tubes 202 are assembled at 90° on the rotary drum 201 and the adsorption tubes 202 are oriented towards the direction of paint mist flow, the transmission rack 301 can drive the two rows of adsorption tubes 202 on the rotary drum 201 to rotate alternately between the main partition 102 and the secondary partition 103 during the reciprocating motion, so that the two cavities on the upper and lower sides of the guide port 104 alternately adsorb and clean the paint mist.

[0034] Please see Figure 1 In a preferred embodiment of this embodiment, the adsorption component 2 further includes a flow guide valve pipe 205 and a water pump 206. A plurality of flow guide valve pipes 205 are movably connected to a plurality of rotary drums 201, and the end of the flow guide valve pipe 205 is connected to the water pump 206.

[0035] In practical application, the guide valve pipe 205 is rotatably connected to the rotary drum 201, preferably using a rotary sealing joint. This allows the water pump 206 to continuously supply water to the rotary drum 201 through the guide valve pipe 205 during rotation. Water overflows from the overflow hole 203 on one side of the adsorption pipe 202 and flows over the surface of the adsorption pipe 202, continuously rinsing the adsorbed paint mist particles. Combined with the rotating brush of the cleaning brush 401, periodic cleaning is performed, ensuring that the adsorption pipes 202 are always clean and preventing paint mist particles from sticking and solidifying between the adsorption pipes 202.

[0036] Please see Figure 2 and Figure 5 In a preferred embodiment of the invention, the transmission component 3 further includes an elastic groove 302 and an outer convex surface 305. The elastic groove 302 is fixedly arranged on one side of the main housing 101 and is in sliding elastic contact with the transmission rack 301. The outer convex surface 305 is fixedly arranged on one end of the abutment wheel 304.

[0037] In practical application, the transmission rack 301 is elastically mounted to one side of the main housing 101 via the elastic groove 302. Since the abutment wheel 304 has a convex surface 305 on one side, and the diameter of the convex surface 305 is not equal to that of the abutment wheel 304, when the abutment part 303 elastically abuts against the abutment wheel 304, the drive motor assembly 6 drives the abutment wheel 304 to rotate. One end of the abutment wheel 304 is a semi-circular surface, and the center distance between the abutment part 303 and the abutment wheel 304 remains constant during the sliding process, ensuring effective abutment. Part 303 remains stationary at its current vertical height. When part 303 slides to the side of the outer convex surface 305 via the abutting wheel 304, the radius of the outer convex surface 305 is not equal to that of the abutting wheel 304, causing part 303 to slide synchronously in the vertical direction. This causes several transmission racks 301 to drive the driven gear shaft 204 to rotate, so that the rotary drum 201 rotates in the guide port 104. The rotation frequency of the rotary drum 201 is linearly related to the contact time between part 303 and the abutting wheel 304 and the outer convex surface 305.

[0038] Please see Figure 2 In a preferred embodiment of the invention, the sealing member 7 further includes an insert plate 703 and a drive plate 704. A plurality of insert plates 703 are arranged between the main partition 102 and the secondary partition 103 and are located close to the two sets of elastic plates 701. One end of the drive plate 704 is fixedly connected to a plurality of insert plates 703, and the other end is elastically slidably assembled in the main housing 101.

[0039] In practical application, when the pressure drive plate 704 overcomes the elastic force and moves the insert plates 703 toward the two sets of magnetic balls 702, the insert plates 703 squeeze the magnetic balls 702 apart. Due to the elastic force of the elastic sheet 701 itself, the elastic sheets 701 on both sides separate. Under the action of inertia, the elastic sheet 701 bounces in the opposite direction and bounces toward the adjacent elastic sheet 701. The same applies to the elastic sheet 701 on the adjacent side, so that the two elastic sheets 701 are attracted again to form a sealing structure.

[0040] Please see Figure 2 In a preferred embodiment of the invention, the blocking component 7 further includes a reciprocating cam 705, one end of which is movably abutted against the drive plate 704, and the other end is assembled and connected to the drive motor assembly 6, for driving the reciprocating motion of the insert plate 703.

[0041] In practical application, the reciprocating cam 705 rotates periodically under the drive of the drive motor group 6, and the convex surface presses against one side of the drive plate 704.

[0042] In one embodiment, the drive motor unit 6 is a transmission unit equipped with several transmission gear sets. As long as it can drive the rotation of the abutment wheel 304, the transmission belt 403 and the reciprocating cam 705, it is a common drive unit without specific structural limitations.

[0043] In one embodiment, during the rotation of the reciprocating cam 705, the action of pressing the drive plate 704 toward the magnetic ball 702 is considered an instantaneous action. After the two sets of magnetic balls 702 are separated, the drive plate 704 drives several insert plates 703 to move instantly to the initial position without interfering with the subsequent magnetic ball 702 adsorption action.

[0044] The above embodiments of the present invention provide a water-based paint mist separation device, which, through a plurality of cavities arranged between the main partition 102 and the secondary partition 103, and the adsorption assembly 2 rotatably assembled between the cavities, can adsorb and quickly remove water-based paint mist during periodic rotation, and can realize the cyclic processing of continuously input paint mist to prevent paint from clogging and sticking.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
