Description

Technical Field

[0001] The utility model belongs to the technical field of air filtration, and in particular relates to a wooden frame type mixed filter material paint mist collecting device. Background Art

[0002] During the painting process, a large amount of paint mist particles are entrained in the air and diffused into the work environment. These paint mist particles not only pollute the environment but also pose a threat to the health of operators. Therefore, effective paint mist collection and filtration technology is particularly important in the painting process.

[0003] Common paint mist filtration devices currently on the market primarily rely on a single type of filter material, such as filter paper, glass fiber, or electrostatic filtration. While these devices can filter out paint mist particles to a certain extent, due to the diversity of paint mist particles and the differences in different painting processes, a single type of filter material often fails to effectively filter all different types of particles. Furthermore, the long-term use of a single filter material can easily lead to a decrease in filtration efficiency, increasing the frequency and cost of equipment maintenance. Furthermore, traditional filtration devices experience a conflict between filtration efficiency and ventilation effectiveness: as filtration efficiency increases, ventilation effectiveness often decreases, leading to increased energy consumption.

[0004] In the prior art, although some devices improve the filtering effect by stacking multiple layers of similar filter materials, due to the lack of comprehensive application of multiple materials, there are still problems such as incomplete filtration and poor equipment operation stability. Utility Model Content

[0005] In response to the problems existing in the prior art, the purpose of the present utility model is to provide a wooden frame type mixed filter material paint mist collection device, which can optimize the air flow path and the separation effect of the filter particles during the filtration process by introducing the combined use of multiple filter materials, thereby ensuring efficient filtration while improving the operating stability and service life of the equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A wooden frame type mixed filter material paint mist collection device, comprising a frame assembly, the frame assembly comprising a bottom frame and a top frame, and a second DPA filter unit connected to each of the four corners between the bottom frame and the top frame;

[0008] A dividing strip is provided on the inner side of the top frame, which divides the frame assembly into two areas D and E;

[0009] A first DPA filter unit and a second DPA filter unit are provided in the D region, and the first DPA filter unit and the second DPA filter unit are staggered and arranged at equal intervals;

[0010] A glass fiber filter unit is installed in area E;

[0011] A third DPA filter unit is provided on the inner side of one end of the frame assembly.

[0012] Furthermore, the first DPA filter unit is arranged on the midline of the D region, and the second DPA filter units are symmetrically distributed on both sides inside the D region.

[0013] Furthermore, the overlapping distance between the second DPA filter unit and the first DPA filter unit is set to A, the spacing between the second DPA filter units arranged opposite to each other is set to B, and the spacing between adjacent first DPA filter units and second DPA filter units is set to C;

[0014] A:B:C=5:2:1.

[0015] Furthermore, the number of the glass fiber filter units is arranged in multiple rows, and the glass fiber filter units in the multiple rows are staggered with each other.

[0016] Furthermore, both ends of the glass fiber filter unit are provided with pipe network constraint plates, and the pipe network constraint plates are used to limit the position of the glass fiber filter unit.

[0017] Furthermore, a positioning hole corresponding to the glass fiber filter unit is formed through the upper end surface of the pipe network constraint plate.

[0018] Furthermore, lower pressing bars are symmetrically arranged inside the top frame, and the lower pressing bars are against the tops of the first DPA filter unit and the second DPA filter unit.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] A divider strip within the device divides the frame assembly into two zones, D and E. Zone D houses the first and second DPA filter units, staggered at equal intervals to create an optimized internal path. This design ensures that air passing through zone D fully contacts the filter material, achieving highly effective paint mist particle filtration. Through the synergistic effect of the first and second DPA filter units, the majority of overspray particles carried in the air are effectively separated and adsorbed.

[0021] Within Area E, glass fiber filter elements are installed in a densely packed pattern, further separating paint mist particles through turbulence. The staggered arrangement of multiple rows of glass fiber filter elements enhances the turbulence within the filter, further allowing paint mist particles to settle and be adsorbed, improving filtration efficiency. The use of glass fiber filter elements solves the problem of a single filter material being unable to effectively filter a wide range of particles while ensuring stable operation.

[0022] To ensure the stability and precise positioning of the filter units, each fiberglass filter unit is equipped with a pipe network restraint plate with corresponding positioning holes. Made of corrosion-resistant material, the pipe network restraint plate maintains structural stability over extended use and resists deformation due to environmental factors. The positioning holes ensure that each fiberglass filter unit is precisely fixed in its intended position, preventing displacement caused by air flow and further ensuring the stable operation of the filter unit.

[0023] Symmetrically positioned inside the top frame are lower pressure bars, made of an elastic material. These bars exert a certain pressure on the filter units during operation, ensuring they maintain close contact and prevent loosening or displacement due to air flow. This design not only improves filtration efficiency but also extends the service life of the filter units, reducing maintenance costs and frequency. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0035] See Figure 1-4 , a wooden frame type mixed filter material paint mist collection device, including a frame assembly 1, the frame assembly 1 includes a base frame 11 and a top frame 12, and the four corners between the base frame 11 and the top frame 12 are connected to a second DPA filter unit 3; the base frame 11 is made of high-strength wood to ensure the stability and durability of the entire device; the top frame 12 is also made of high-strength wood, and its structural design not only ensures the stability of the frame, but also facilitates installation and maintenance; a dividing strip 121 is provided on the inner side of the top frame 12, and the dividing strip 121 divides the frame assembly 1 into two areas D and E; a first DPA filter unit 2 and a second DPA filter unit 3 are provided in the D area, and the first DPA filter unit 2 and the second DPA filter unit 3 are arranged at equal intervals to form an internal channel; a glass fiber filter unit 4 is provided in the E area, and the glass fiber filter unit 4 is installed in the E area in a densely arranged manner to further separate the paint mist particles through the turbulent effect; a third DPA filter unit 6 is provided on the inner side of one end of the frame assembly 1, and the third DPA filter unit 6 further improves the filtering effect of the entire device.

[0036] See Figure 1-2 The first DPA filter unit 2 is arranged on the midline of the D area, and the second DPA filter unit 3 is symmetrically distributed on both sides of the interior of the D area; the first DPA filter unit 2 and the second DPA filter unit 3 are both made of high-efficiency filter materials, and their surfaces are covered with DPA cotton, which can effectively absorb paint mist particles in the air; this staggered arrangement ensures that when the air passes through the D area, the overspray particles can fully contact the filter material, thereby achieving efficient filtration.

[0037] See Figure 2 The overlapping distance between the second DPA filter unit 3 and the first DPA filter unit 2 is set to A, the spacing between the oppositely arranged second DPA filter units 3 is set to B, and the spacing between adjacent first DPA filter units 2 and second DPA filter units 3 is set to C; A:B:C=5:2:1. This spacing setting not only optimizes the air flow path, but also maximizes the filtration efficiency, ensuring the best filtration effect in a limited space.

[0038] See Figure 2The number of glass fiber filter units 4 is set to multiple rows, and the multiple rows of glass fiber filter units 4 are staggered with each other; this arrangement of the glass fiber filter units 4 enhances the turbulent effect of the filtering device, so that the paint mist particles in the air can be further settled and adsorbed when passing through the E area, thereby improving the filtration efficiency; each row of glass fiber filter units 4 is made of high-strength glass fiber, which can maintain a stable filtration effect for a long time.

[0039] See Figure 1-4 , both ends of the glass fiber filter unit 4 are provided with pipe network constraint plates 5, which are used to limit the position of the glass fiber filter unit 4; the pipe network constraint plates 5 are made of corrosion-resistant materials, which can maintain structural stability during long-term use and will not be deformed due to moisture or other environmental factors; this design not only ensures the stability of the glass fiber filter unit 4, but also facilitates the maintenance and replacement of the device.

[0040] See Figure 2 and Figure 4 The upper end surface of the pipe network constraint plate 5 is penetrated with positioning holes 51 corresponding to the glass fiber filter units 4; the design of these positioning holes 51 enables each glass fiber filter unit 4 to be accurately fixed in a predetermined position, preventing displacement caused by air flow, and further ensuring the stable operation of the filtering device.

[0041] See Figure 1 The top frame 12 is symmetrically provided with lower pressure strips 122 inside, which are against the top of the first DPA filter unit 2 and the second DPA filter unit 3; the lower pressure strips 122 are made of elastic material and can generate a certain pressure on the filter unit during the operation of the device, ensuring that the filter unit always maintains close contact and will not become loose or displaced due to air flow. This design not only improves the filtration efficiency, but also extends the service life of the filter unit.

[0042] The working principle of this utility model is:

[0043] Air carrying overspray particles enters the paint mist collection device from the air inlet and first enters area D. In area D, the air carrying overspray particles flows through the internal channel formed by the first DPA filter unit 2 and the second DPA filter unit 3. The overspray particles are separated from the air, and most of the overspray particles either settle or are adsorbed by the DPA cotton on the surface of the first and second DPA filter units.

[0044] The air carrying overspray particles then enters area E. In area E, after being subjected to turbulent separation by the densely arranged glass fiber pipe network filter units 4, the overspray particles further settle and are adsorbed, and finally reach the air outlet through the third DPA filter unit 6.

[0045] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
