Description

Technical Field

[0001] The utility model belongs to the technical field of air purification, and particularly relates to a dry paint mist separation device capable of real-time monitoring of the internal structure. Background Art

[0002] During the spray painting operation, paint mist is a common pollutant, which has adverse effects on both the environment and the health of operators. In order to reduce the environmental pollution caused by paint mist, paint mist separation devices are usually used for treatment. At present, most of the paint mist separation devices on the market rely on wet separation methods, that is, the paint mist is separated from the air by means of water washing, spraying, etc. However, the wet separation method has some defects, such as large water resource consumption, complex equipment maintenance, and the need for wastewater treatment after treatment.

[0003] As an alternative, the dry paint mist separation device can effectively avoid the above problems. However, the existing dry paint mist separation devices also have some deficiencies.

[0004] Firstly, since the state of the internal filter material cannot be monitored in real time, it is difficult for operators to judge when the filter material needs to be replaced, which may lead to a decrease in the working efficiency of the equipment or equipment failures caused by filter material blockage. Secondly, the filtration efficiency of the existing devices needs to be improved. Especially when the paint mist particles are relatively fine, it is often difficult to completely remove the paint mist particles in the air. In addition, the layout of the filter materials also affects the overall performance of the device. The conventional design cannot make full use of the airflow characteristics, resulting in some impurities not being evenly adsorbed on the filter material. Summary of the Utility Model

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a dry paint mist separation device capable of real-time monitoring of the internal structure, which can realize real-time monitoring of the internal structure and improve the filtration efficiency.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A dry paint mist separation device capable of real-time monitoring of the internal structure includes a cardboard outer shell. The shape of the cardboard outer shell is set as a "C" shape, and a cardboard support groove is provided at the bottom of the cardboard outer shell. A wind guide plate is provided at the top of the cardboard outer shell, and a detachable back plate is provided at the open end of the side of the cardboard outer shell;

[0008] The space formed by the cardboard outer shell, the cardboard support groove, the wind guide plate and the detachable back plate is set as an overspray paint mist treatment chamber;

[0009] A first plate-shaped filtering unit and a second plate-shaped filtering unit are symmetrically arranged inside the overspray paint mist treatment chamber;

[0010] One side of the first plate-shaped filtering unit is provided with a wooden frame support;

[0011] The other side of the first plate-shaped filtering unit is provided with a polystyrene semi-circular tile;

[0012] Both sides of the second plate-shaped filtering unit are provided with second tubular filtering units, and a first tubular filtering unit is arranged between the second plate-shaped filtering unit and the detachable back plate.

[0013] Further, cross bars are evenly distributed along the height direction on the inner side of the wooden frame support, and a first ribbon and a second ribbon are sequentially and evenly arranged on the outer sides of the plurality of cross bars.

[0014] Further, the number of the first ribbons is set to be an even number, the number of the second ribbons is set to be an odd number, and the first ribbons and the second ribbons are arranged in an alternating manner.

[0015] Further, the number of the polystyrene semi-circular tiles is set to be two, and the two polystyrene semi-circular tiles are distributed on both sides of the central axis of the cardboard support groove.

[0016] Further, a through hole is formed through the side surface of the detachable back plate, an inner frame is fitted inside the through hole, and a fiberglass cotton paint mist cotton board is arranged inside the inner frame.

[0017] Further, a positioning groove is formed at one end of the inner side of the inner frame, and a fixed plate and a movable plate are respectively arranged at the top and bottom of the side surface of the inner frame. The fixed plate is fixedly connected with the inner frame, and the movable plate is rotatably connected with the inner frame.

[0018] Further, a transparent plate is arranged on the outer side of the cardboard shell, and the transparent plate is close to the position where the wooden frame support is located.

[0019] Further, an upper tube bundle plate and a lower tube bundle plate are respectively arranged at the top and bottom inside the overspray mist treatment chamber, and the first tubular filtering unit and the second tubular filtering unit are fixed between the upper tube bundle plate and the lower tube bundle plate.

[0020] Further, a wooden cushion block is arranged at the bottom of the lower tube bundle plate; a wooden tray is arranged at the bottom of the cardboard support groove.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] First, by setting a transparent plate on the outer side of the cardboard shell, this device enables operators to observe the impurity adsorption situation inside the cardboard shell in real time. This design allows operators to replace the filter material in a timely manner, avoiding the problem that traditional devices cannot monitor the internal state, thereby ensuring the long-term and efficient operation of the device. This real-time monitoring method greatly improves the maintainability and service life of the equipment, and solves the equipment failure problem caused by filter material blockage.

[0023] Secondly, the present utility model optimizes the design of the air flow path and the filtering unit. By arranging a plurality of filtering units such as a wind guiding plate, a first plate-shaped filtering unit, a second tubular filtering unit, a second plate-shaped filtering unit, and a first tubular filtering unit inside the cardboard shell, the air flow filters the paint mist and impurities in the air layer by layer when passing through these units. In particular, the first ribbon and the second ribbon arranged can disturb the air flow entering the device interior, enabling the impurities in the air to be evenly adsorbed on each filtering device. This multi-level and multi-stage filtering method greatly improves the separation efficiency of impurities in the air, especially significantly enhancing the capturing ability for fine paint mist particles.

[0024] In addition, by utilizing the eddy current formed by the polystyrene semi-circular tiles during the filtering process, the impurities in the air are more evenly adsorbed on the first tubular filtering unit, the second tubular filtering unit, and the second plate-shaped filtering unit. This structural design not only improves the capturing efficiency of impurities, but also effectively avoids the problem of local overloading of the filtering device, thereby extending the service life of the filtering device.

[0025] Finally, the detachable back panel design of the device makes the replacement of the filtering device more convenient. By arranging structures such as an inner frame, a fiberglass cotton and paint mist cotton board, a positioning groove, a fixing plate, and a movable plate, operators can easily open the back panel for internal inspection and filter material replacement. This convenient maintenance design solves the problems of difficult maintenance and complex operation of traditional devices, and improves the overall operability and maintainability of the equipment.

[0044] In order to make the purpose and advantages of the present utility model more clear and understandable, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0045] Refer to Figures 1-6, A dry paint mist separation device capable of real-time monitoring of the internal structure, including a cardboard outer shell 1. The shape of the cardboard outer shell 1 is set as a "C" shape, and a cardboard support groove 3 is provided at the bottom of the cardboard outer shell 1. A wind guide plate 5 is provided at the top of the cardboard outer shell 1, and a detachable back plate 9 is provided at the side opening end of the cardboard outer shell 1; the space formed by the cardboard outer shell 1, the cardboard support groove 3, the wind guide plate 5 and the detachable back plate 9 is set as an overspray mist treatment chamber 10; a first plate-shaped filtering unit 14 and a second plate-shaped filtering unit 141 are symmetrically arranged inside the overspray mist treatment chamber 10; a wooden frame support 15 is provided on one side of the first plate-shaped filtering unit 14; a polystyrene semi-circular tile 13 is provided on the other side of the first plate-shaped filtering unit 14; second tubular filtering units 12 are provided on both sides of the second plate-shaped filtering unit 141, and a first tubular filtering unit 11 is provided between the second plate-shaped filtering unit 141 and the detachable back plate 9; during use, the air containing paint mist enters the inside of the cardboard outer shell 1 through the opening between the wind guide plate 5 and the cardboard outer shell 1. At this time, the air flow entering the inside of the cardboard outer shell 1 will first come into contact with the first ribbon 152 and the second ribbon 153. Under the disturbance of the first ribbon 152 and the second ribbon 153, the mixture in the air entering the inside of the cardboard outer shell 1 is dispersed, so that the impurities in the air are evenly adsorbed on the filtering equipment.

[0046] Refer to Figures 2-5 , inside the wooden frame support 15, cross bars 151 are evenly distributed along its height direction, and a first ribbon 152 and a second ribbon 153 are sequentially and evenly arranged on the outer sides of the plurality of cross bars 151; during the air purification process, the air flow is disturbed and passes through each filtering unit. The disturbed air sequentially passes through the first plate-shaped filtering unit 14, the second tubular filtering unit 12, the second plate-shaped filtering unit 141 and the first tubular filtering unit 11, and finally is discharged to the outside of the cardboard outer shell 1 through the detachable back plate 9.

[0047] Refer to Figures 2-5 , the number of the first ribbons 152 is set as an even number, the number of the second ribbons 153 is set as an odd number, and the first ribbons 152 and the second ribbons 153 are arranged in an interleaved manner; this design can make the air flow produce a better disturbance effect when passing through the filtering unit, thereby improving the capture efficiency of impurities.

[0048] Refer to Figures 3-4 , the number of the polystyrene semi-circular tiles 13 is set as two, and the two polystyrene semi-circular tiles 13 are distributed on both sides of the central axis of the cardboard support groove 3; when the air flow impacts on the polystyrene semi-circular tiles 13, since the polystyrene semi-circular tiles 13 are set as semi-circular rings, the air flow forms a vortex, so that the impurities in the air can be evenly adsorbed on the first tubular filtering unit 11, the second tubular filtering unit 12 and the second plate-shaped filtering unit 141.

[0049] Refer toFigure 6 On the side of the detachable back panel 9, there is a through opening 91 running through it. Inside the through opening 91, there is an inner frame 92 fitted. Inside the inner frame 92, there is a fiberglass cotton paint mist cotton board. At one end of the inner side of the inner frame 92, there is a positioning groove 921. And at the top and bottom of the side of the inner frame 92, there are a fixed plate 93 and a movable plate 94 respectively. The fixed plate 93 is fixedly connected to the inner frame 92, and the movable plate 94 is rotatably connected to the inner frame 92. Through these designs, it is possible to conveniently inspect and replace the internal filter materials, ensuring the long-term efficient operation of the filtering device.

[0050] Refer to Figure 1 On the outside of the cardboard shell 1, there is a transparent plate 2, and the transparent plate 2 is close to the position where the wooden frame support 15 is located. Through the transparent plate 2, the situation of impurity adsorption inside the cardboard shell 1 can be clearly observed, and thus the filter materials can be replaced in a timely manner.

[0051] Refer to Figure 2 At the top and bottom inside the overspray mist treatment chamber 10, there are an upper tube bundle plate 6 and a lower tube bundle plate 7 respectively. The first tubular filtering unit 11 and the second tubular filtering unit 12 are fixed between the upper tube bundle plate 6 and the lower tube bundle plate 7. This design ensures that each tubular filtering unit can be firmly fixed inside the treatment chamber, improving the stability and efficiency of the filtering process.

[0052] Refer to Figure 2 At the bottom of the lower tube bundle plate 7, there is a wooden cushion block 8; at the bottom of the cardboard support groove 3, there is a wooden tray 4. These wooden structures ensure the stability of the overall device and provide additional support to prevent the equipment from tilting or moving during operation.

[0053] The working principle of the present utility model is as follows:

[0054] When in use, the air containing paint mist will enter the inside of the cardboard shell 1 through the through opening between the air guide plate 5 and the cardboard shell 1. At this time, the air flow entering the inside of the cardboard shell 1 will first come into contact with the first ribbon 152 and the second ribbon 153. Under the disturbance of the first ribbon 152 and the second ribbon 153, the mixture in the air entering the inside of the cardboard shell 1 will be dispersed, so that the impurities in the air can be evenly adsorbed on the filtering equipment.

[0055] The disturbed air will then sequentially pass through the first plate-shaped filtering unit 14, the second tubular filtering unit 12, the second plate-shaped filtering unit 141, and the first tubular filtering unit 11, and finally be discharged to the outside of the cardboard shell 1 through the detachable back panel 9.

[0056] When the airflow hits the polystyrene semicircular tile 13, since the polystyrene semicircular tile 13 is set in a semi-circular shape, the airflow will form a vortex, which makes it easier for impurities in the air to be evenly adsorbed on the first tubular filter unit 11, the second tubular filter unit 12 and the second plate filter unit 141; at the same time, the polystyrene semicircular tile 13 has a corresponding semicircular structure, which will have a certain rigidity and can also play a role in making the wind swirl and changing the wind direction to a certain extent, thereby facilitating the optimization of the spatial layout; if the curvature corresponding to the polystyrene semicircular tile 13 is larger, the difficulty of wind entering and exiting at this location will become greater.

[0057] During the air purification process, the impurity adsorption inside the paperboard shell 1 can be clearly observed through the transparent plate 2, so that the filter material can be replaced in time.

[0058] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
