[0026] Please see Figures 1 to 5The present invention provides an embodiment of a high-efficiency dust treatment device for a furniture spray painting booth. The dust treatment device includes a trolley 1, a centrifugal fan 2, a connecting pipe 3, a filter element 4, and a collection element 5. The centrifugal fan 2 is located on the top of the trolley 1, the connecting pipe 3 is located at the air outlet of the centrifugal fan 2, and the filter element 4 is located between the centrifugal fan 2 and the collection element 5.
[0027] The trolley 1 serves as the mobile base of the device, facilitating flexible movement and positioning within the paint booth to adapt to different work scenarios. The centrifugal fan 2 is the core power component, which uses negative pressure to adsorb dust-laden air and drives the airflow through the filtration system to separate dust from air. The connecting pipe 3 connects the air outlet of the centrifugal fan 2 to the external exhaust pipe, guiding the purified air out and ensuring unobstructed airflow path.
[0028] The filter element 4 includes a filter screen 44 and a filter plate 47. The filter screen 44 is disposed at the air inlet of the centrifugal fan 2. The filter plate 47 is located at the end of the filter screen 44 away from the centrifugal fan 2. The filter plate 47 includes V-shaped columns 471, fixing strips 472 and connecting holes 473. The fixing strips 472 are fixed between the V-shaped columns 471. The V-shaped columns 471 and the fixing strips 472 are integrally formed. The connecting holes 473 are opened inside the fixing strips 472 and are evenly distributed along the vertical direction of the fixing strips 472.
[0029] The filter screen 44 is a secondary filter layer that traps fine dust particles that are not captured by the V-shaped column 471. The V-shaped column 471 forms turbulence and efficiently captures large dust particles through inertial collision. The fixing strip 472 is used to support the structure of the V-shaped column 471, and the connecting hole 473 allows airflow to pass through and maintains wind pressure stability.
[0030] The filter element 4 also includes a support column 41, a support frame 42, and a first connecting strip 43; the support column 41 is fixed to the upper surface of the trolley 1, the support frame 42 is fixed to the upper surface of the support column 41, the first connecting strip 43 is inserted into the inside of the support frame 42, and the upper surface of the first connecting strip 43 is fixed to the lower surface of the filter screen 44.
[0031] The support column 41 is used to support and install the support frame 42. The support frame 42 is used to accommodate the first connecting strip 43 and the second connecting strip 45, thereby enabling the disassembly and assembly of the filter screen 44 and the filter plate 47. The first connecting strip 43 is used to fix the filter screen 44 in the required position.
[0032] A second connecting strip 45 is fixed to the lower surface of the filter plate 47. The second connecting strip 45 is inserted into the inside of the support frame 42. A guide plate 46 is fixed to the top surface of the second connecting strip 45.
[0033] The second connecting strip 45 is used to support and install the filter plate 47, and the guide plate 46 guides the dust trapped by the filter plate 47 to slide down to the collection frame 51 to avoid secondary re-entrainment.
[0034] The first connecting strip 43 and the second connecting strip 45 are connected to the internal threads of the support frame 42 by screws 48;
[0035] Screw 48 is used to securely fix the first connecting strip 43 and the second connecting strip 45 inside the support frame 42;
[0036] The collecting component 5 includes a collecting frame 51, a fixing post 52, and a fixing pipe 54; the collecting frame 51 is located at the bottom of the guide plate 46, the fixing post 52 is fixed on the surface of the collecting frame 51 near the centrifugal fan 2, and the fixing pipe 54 passes through and connects the fixing post 52 and the interior of the support post 41.
[0037] The collection frame 51 is used to store the dust captured by the filtration system, the fixing column 52 is used to cooperate with the support column 41 to fix the collection frame 51 to the desired position, and the fixing tube 54 is used to confine the fixing column 52 inside the support column 41.
[0038] A guide block 53 is fixed on the outer surface of the fixing tube 54, a magnet block 55 is fixed inside the fixing tube 54, and a connecting post 56 is fixed on the surface of the inner magnet block 55. The cross-section of the connecting post 56 is convex, and the connecting post 56 is inserted inside the fixing tube 54.
[0039] The guide block 53 facilitates the removal of the fixing tube 54 from the inside of the support column 41, while the magnet block 55 is used to restrict the connecting column 56 inside the fixing tube 54. The connecting column 56 is used to restrict the fixing tube 54 inside the support column 41.
[0040] A limit frame 6 is fixed on the upper surface of the end of the trolley 1 away from the centrifugal fan 2. A cover plate 7 is snapped into the inside of the limit frame 6. Guide frames 8 are fixed on both sides of the cover plate 7.
[0041] The limiting frame 6 is used to restrict the cover plate 7 to the top of the trolley 1. The cover plate 7 is used to lock the top of the collection box 51 to prevent dust from flying when the collection box 51 is moved. The guide frame 8 facilitates the movement of the cover plate 7 to the required position.
[0042] Working principle: When dust treatment is required, the device is first pushed into the paint booth by the trolley 1, and then the exhaust pipe and connecting pipe 3 are connected together. Then, the centrifugal fan 2 is started. The air intake of the centrifugal fan 2 draws in the airflow. When the airflow moves to the air intake of the centrifugal fan 2, the V-shaped column 471 can capture the dust in the air more efficiently. With the design of the connecting hole 473, the filtered air is filtered a second time by the filter screen 44 and then discharged through the exhaust pipe, thus treating the dust more efficiently. At the same time, the dust filtered by the V-shaped column 471 will flow into the collection frame 51 through the guide plate 46.
[0043] When dust inside the collection box 51 needs to be removed, a pulling force is applied to the guide block 53 and the connecting post 56, causing the connecting post 56 and the fixing tube 54 to disengage from the fixing post 52 and the support post 41. Then, a pulling force is applied to the collection box 51, and after the collection box 51 is placed on the trolley 1, a pulling force is applied to the guide frame 8 to remove the cover plate 7 from inside the limiting frame 6. Then, the cover plate 7 is placed on top of the collection box 51, and the collection box 51 is moved to the required location for processing.
[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
