Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying workbenches, in particular to an environmentally friendly topcoat spraying workbench. Background Art

[0002] In the field of modern industrial manufacturing, the painting process is an indispensable part. It not only gives the product a beautiful appearance, but also provides the necessary protection function. As a professional platform for performing this key process, the design and performance of the painting workbench directly affect the quality of painting, production efficiency and environmental sustainability. Traditional painting workbenches integrate sophisticated painting equipment, which can strictly control the temperature, humidity, light intensity and air cleanliness of the working environment to ensure the efficiency and stability of the painting process. More importantly, they are also equipped with advanced exhaust gas treatment systems, which are designed to capture and purify the paint mist and harmful exhaust gas generated during the painting process to meet environmental protection standards and ensure the health and safety of operators.

[0003] However, under the existing technical framework, the treatment of paint mist at the paint spraying workbench mainly relies on water curtain filtration technology, that is, using water flow to form a curtain to capture paint mist particles. However, since paint mist usually contains oily components and has a weak affinity with water, this leads to the limitations of the water curtain filtration effect, making it difficult to achieve complete capture of paint mist. In order to improve this situation, some solutions have tried to enhance the capture ability of the water curtain by adding paint mist coagulants, but the nature of the water-based absorption medium limits the effectiveness of this method, and there is limited room for improvement.

[0004] In view of this, the inventor specially designed an environmentally friendly topcoat spraying workbench, and this case was produced. Utility Model Content

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] See also Figures 1 to 4 , is an environmentally friendly topcoat spraying workbench as the best embodiment of the utility model, comprising:

[0041] The box body 10 is in a rectangular parallelepiped shape as a whole, and a cavity 11 with an opening on one side is formed therein;

[0042] The paint spraying seat 20 is provided at the opening side of the cavity 11 and is used for placing the sample to be sprayed with paint;

[0043] The oil pool 30 is provided at the bottom of the cavity 11 and is lower than the lowest position of the opening of the cavity 11. The oil for absorbing the paint mist is stored inside the oil pool. The lowest position of the opening limits the oil from overflowing.

[0044] The oil curtain structure 40 includes a first oil curtain plate 41 and a second oil curtain plate 42 which are parallel and vertically arranged along the top of the cavity 11. The bottom of the first oil curtain plate 41 is higher than the liquid level of the oil pool 30. The surface of the second oil curtain plate 42 is provided with a plurality of vents 43 and the bottom thereof penetrates into the liquid level of the oil pool 30. The first oil curtain plate 41 and the second oil curtain plate 42 sequentially divide the cavity 11 into a spraying area 12 close to the opening, an absorption area 13 and a discharge area 14.

[0045] The oil curtain forming device 50 is provided with two and is respectively disposed on one side of the first oil curtain plate 41 and the second oil curtain plate 42 close to the painting area 12, including a plurality of oil spray pipes 51 disposed in parallel in front of the first oil curtain plate 41 and the second oil curtain plate 42, an oil delivery pipe 52 sequentially connected to the plurality of oil spray pipes 51, and a plurality of nozzles 53 disposed on the oil spray pipes 51;

[0046] In this embodiment, the fuel injection pipe 51 is fixed to the top of the cavity 11 through a hanging rod.

[0047] The negative pressure exhaust device 60 is arranged at the top of the exhaust area 14, and includes a negative pressure fan 61 and an exhaust pipe 62. In order to further enhance the filtering effect, a primary filter (not shown in the figure) is arranged at the inlet end of the exhaust pipe 62;

[0048] The spraying directions of the plurality of nozzles 53 are all inclined downward and toward the first oil curtain plate 41 or the second oil curtain plate 42 .

[0049] The oil used in this embodiment is 45# engine oil, and the nozzle 53 is an atomizing nozzle 53. In the working state, the nozzle 53 sprays oil toward the first oil curtain plate 41 and the second oil curtain plate 42 to form a continuous oil curtain on the first oil curtain plate 41 and the second oil curtain plate 42 to absorb paint mist. After the negative pressure fan 61 is started, the excess paint mist generated by spraying paint in the paint spraying area 12 is sequentially guided to the absorption area 13 and the discharge area 14. When the paint mist enters the absorption area 13 through the paint spraying area 12, it enters the absorption area 13 through the gap between the first oil curtain plate 41 and the liquid surface of the oil pool 30. When the oil flows down in the gap, a curtain is formed to absorb a certain amount of the paint mist passing through. In addition, the oil sprayed from the oil injection pipe 51 and the nozzle 53 in the absorption area 13 causes the paint mist to be absorbed again. When the remaining paint mist passes through the vent hole 43, it is absorbed again by the oil on the second oil curtain plate 42. Finally, the exhaust gas that has been absorbed is discharged through the exhaust pipe 62.

[0050] Preferably, Figure 1 As shown, a plurality of oil injection pipes 51 are staggered in the vertical direction and the injection area of ​​the nozzle 53 covers the surface of the first oil curtain plate 41 or the second oil curtain plate 42 , so that the oil forms a uniform film on the first oil curtain plate 41 and the second oil curtain plate 42 .

[0051] Preferably, Figure 1 As shown, one end of the oil delivery pipe 52 extends into the oil pool 30 and is connected to an oil delivery pump (not shown in the figure). The oil delivery pipe 52 is serpentine and sequentially connected to a plurality of oil injection pipes 51 .

[0052] Preferably, Figure 2 , 3As shown, one side of the first oil curtain plate 41 close to the paint spraying area 12 is an uneven rough surface, which helps to evenly distribute the oil on the oil curtain plate, increase the residence time and contact area of ​​the oil, and thus increase the probability of paint mist being captured, so that the paint mist particles drifting out of the paint spraying area 12 have more opportunities to contact with the oil and be adsorbed.

[0053] Preferably, Figure 2 , 3 As shown, an overflow groove 411 is provided on the top of the first oil curtain plate 41. The oil in the oil pool 30 circulates in the overflow groove 411 and its overflow port is connected to the rough surface of the first oil curtain plate 41. In this embodiment, the overflow groove 411 is supplemented with oil through an oil pump branch so that it is filled with oil. With the help of the overflow groove 411, the oil can be more evenly left along the top of the first oil curtain plate 41, increasing the probability of forming an oil curtain, so that the paint mist particles can be better absorbed.

[0054] Preferably, Figure 3 As shown, an inclined guide surface 412 is provided between the overflow port and the rough surface, so that the oil can flow toward the first oil curtain plate 41 more stably.

[0055] Preferably, Figure 2 As shown, a plurality of oil spray pipes 51 disposed on the front side of the second oil curtain plate 42 are also provided with a plurality of nozzles 53 spraying toward the absorption area 13 .

[0056] Preferably, Figure 2 As shown, the bottom of the cavity 11 is provided with a bottom surface 15 extending obliquely downward along the paint spraying area 12 to the discharge area 14, and the paint spraying seat 20 includes a support rod 21 and a support pad 22 arranged on the support rod 21. The upper half of the support rod 21 is a rotating end that can rotate relative to its lower half, and the rotating end is provided with a plug-in portion 23 extending obliquely upward and having a socket. Therefore, the rotatable and tiltable design of the paint spraying seat 20 allows the operator to insert a rod-shaped control rod into the socket of the plug-in portion 23 to adjust the position and angle of the sample, which is convenient for multi-angle painting and improves the quality and efficiency of painting.

[0057] Preferably, Figure 4 As shown, it also includes an oil changing device, which includes a central control module 70, an oil particle size sensor 71 arranged in the oil pool 30 and electrically connected to the input end of the central control module 70, and a display module 72 electrically connected to the output end of the central control module 70. A de-impurity groove is provided on the side of the box body 10 away from the opening of the cavity 11, the top of the de-impurity groove is connected to the outside and the inside is connected to the oil pool 30, and a cover plate is provided on the top of the de-impurity groove (not marked in the figure).

[0058] In this embodiment, the central control module 70 is an MCU microprocessor, and the display module 72 is a digital display screen. The monitoring data of the oil particle size sensor 71 is displayed in real time on the digital display screen, which is convenient for users to judge the oil turbidity and whether the oil needs to be cleaned or replaced.

[0059] Preferably, Figure 4 As shown, the oil changing device further includes an alarm module 73, which is an audible and visual warning light.

[0060] The utility model adopts oil curtain to replace the traditional water curtain filtering solution, which can more effectively capture the paint mist containing oily components and improve the paint mist capture efficiency. Specifically, its beneficial effects are as follows:

[0061] First, through the oil pool 30 and the oil curtain forming device 50, an oil curtain can be formed on the first oil curtain plate 41 and the second oil curtain plate 42 to better absorb the oily paint mist, significantly improve the capture efficiency of the paint mist, and reduce pollution to the environment.

[0062] Secondly, the arrangement of the oil spray pipe 51 and the nozzle 53 allows the oil to be evenly distributed on the oil curtain plate, forming a continuous oil curtain, thereby enhancing the capture effect of the paint mist. At the same time, the oil is recycled, thereby reducing resource consumption.

[0063] Furthermore, the processed air is discharged through the negative pressure fan 61 and the exhaust pipe 62 to ensure that the inside of the workbench maintains a negative pressure state, prevent paint mist from leaking out, and protect the health of operators.

[0064] In addition, the rough surface of the first oil curtain plate 41 and the overflow groove 411 design increase the coverage area and air permeability of the oil curtain, and further enhance the paint mist capture capability.

[0065] In particular, the impurity content in the oil is monitored by the oil particle size sensor 71. When the set threshold is reached, the central control module 70 will trigger the display module 72 to alarm and replace the oil through the impurity removal tank, thereby realizing automated oil management and maintenance, reducing manual intervention, and improving work efficiency and safety.

[0066] In addition, the rotatable and tiltable design of the paint spraying seat 20 allows the operator to adjust the position of the sample, which is convenient for multi-angle painting and improves the quality and efficiency of painting.

[0067] In summary, the utility model not only effectively solves the limitations of traditional water curtain filtration technology, but also improves the safety and convenience of operation through intelligent management.
