Description

TECHNICAL FIELD

[0001] The utility model belongs to filter device technical field, concretely relates to a paint mist paper box filter. BACKGROUND

[0002] The paint mist paper box filter is mainly applied to the coating industry and filters paint mist through the filter material in the interior. The coating industry produces a large amount of paint mist, and the paint mist particulate matters move with the fluid. When the paint mist particulate matters contact the surface of the filter material, the impurities too close to the surface of the filter material are intercepted. The larger the particle size of the particulate matters, the finer the filter material, and the better the interception effect. When the fluid bypasses the filter medium, the paint mist particulate matters with large inertia directly hit the filter material without bypassing. The larger the particle size, the stronger the inertia, and the greater the possibility of impact and interception, and the better the filtering effect. Therefore, when the paint mist enters the filter, the paint mist is blocked by the honeycomb layer and the filter cotton in sequence and is efficiently captured and left in the paper box, so that the effect of purifying the air in the paint spraying room is achieved.

[0003] However, the existing paint mist paper box filter cannot achieve extremely high filtering efficiency, especially for capturing of small particulate matters, which may result in difficulty in meeting the emission standard or the purified air still containing a certain amount of harmful substances. Meanwhile, the existing paper box on the market is saturated and blocked in a short time due to unreasonable initial resistance or internal structure, especially in a high-load or continuous operation environment, and frequent replacement increases the maintenance cost.

[0021] The utility model will be further described below in conjunction with the drawings. The following examples are only used to more clearly illustrate the technical scheme of the utility model, and cannot limit the protection scope of the utility model.

[0022] Example 1

[0023] The embodiment provides a paint mist carton filter, as shown in the figure, comprising a carton 1, a supporting mechanism and a filtering mechanism. Figures 1-3

[0024] Specifically, the supporting mechanism is arranged in the carton 1, which comprises a first air inlet face support 8, a second air inlet face support 9 and an air outlet face support 7. The first air inlet face support 8 is located on both sides, and the second air inlet face support 8 and the air outlet face support 7 are alternately arranged between the first air inlet face support 8, and the upper and lower ends of the first air inlet face support 8, the second air inlet face support 9 and the air outlet face support 7 all abut the inner wall of the carton 1, so that the supporting force inside the carton 1 can be increased, and the paint capacity can be improved.

[0025] Other air inlet face supports of the paint mist carton filter appearing on the market are mostly integrated structures. According to the experimental test results, the initial resistance of the paint mist carton filter under the same air volume is about 30 Pa lower, and the lower initial resistance can prolong the service life of the filter.

[0026] The filtering mechanism is arranged in a wave shape between the first air inlet face support 8, the second air inlet face support 9 and the air outlet face support 7. The side of the second air inlet face support 9 exposed as an air inlet face, and the side of the air outlet face support 7 exposed as an air outlet face.

[0027] In the embodiment, the second air inlet face support 9 is provided as two, and the air outlet face support 7 is provided as three.

[0028] The filtering mechanism comprises a filter cotton layer 6 and a multi-layer honeycomb paper 5, and the filter cotton layer 6 covers the air outlet face of the multi-layer honeycomb paper 5. The pore diameters of each layer of the multi-layer honeycomb paper 5 are arranged from large to small along the direction from the air inlet face to the air outlet face, so that the filtering efficiency is improved and the durability is enhanced.

[0029] Example 2

[0030] The embodiment provides an implementation of the carton 1, the supporting mechanism and the filtering mechanism based on example 1.

[0031] As​Figure 2 As shown, the first air inlet surface support includes vertical connecting rods 3 and side connecting plates 4. The vertical connecting rods 3 are oppositely arranged along the direction from the air inlet surface to the air outlet surface, and multiple side connecting plates 4 are fixed between the vertical connecting rods 3. In this embodiment, four side connecting plates 4 are arranged to ensure normal air inlet of the air inlet surface and prevent paint mist leakage.

[0032] The second air inlet surface support includes vertical connecting rods 3 and air inlet surface connecting plates 2. The vertical connecting rods 3 are oppositely arranged along the direction from the air inlet surface to the air outlet surface, and multiple air inlet surface connecting plates 2 are fixed between the vertical connecting rods 3. In this embodiment, four air inlet surface connecting plates 2 are arranged.

[0033] Further, the air inlet surface connecting plate 2 is a hollow plate for free settlement of paint mist.

[0034] Further, the width of the air inlet surface connecting plate 2 is greater than that of the side connecting plate 4, which separates two adjacent air inlet channels, increases the air inlet area, and reduces the initial resistance.

[0035] As shown in Figs. Figure 3 and Figure 4 The air outlet surface support 7 is integrally formed and has a trapezoidal horizontal cross section, which is arranged from narrow to wide along the direction from the air inlet surface to the air outlet surface. The air outlet surface support 7 supports the carton 1 together and clamps the filter mechanism in the middle together with the first air inlet surface support and the second air inlet surface support, which has a good sealing effect and effectively prevents paint mist leakage. Meanwhile, the middle is hollow, which increases the air outlet surface area and reduces the resistance. The trapezoidal arrangement helps fluid flow, reduces turbulence, and thus improves the filtering efficiency.

[0036] In this embodiment, each layer of the multi-layer honeycomb paper is made of fire-retardant honeycomb paper, and the carton 1 is made of fire-retardant paper, which optimizes the fire-retardant effect of the filter.
