Description

Technical Field

[0001] This invention relates to the field of oil mist treatment in paint spraying workshops, and in particular to an oil mist treatment system and method for paint spraying workshops. Background Technology

[0002] my country is a major manufacturing country. In some manufacturing workshops, there are usually spray painting workshops. The spray painting workshops are mainly used to spray paint the surfaces of furniture or metal parts to beautify or protect the products.

[0003] Currently, traditional spray painting workshops are generally quite simple in setup. They typically have workbenches set up inside the workshop, with exhaust ducts installed on the side of the workshop near the workbenches. These exhaust ducts are connected to ventilation equipment. Since the air inside the spray painting booth contains a large amount of harmful gases such as paint, an oil mist separator is usually installed on the exhaust ducts. When workers are spray painting products placed on the workbenches, they can turn on the ventilation equipment and the oil mist separator to treat the harmful substances in the spray painting workshop.

[0004] In view of the current technological situation, the inventor believes that traditional oil mist treatment methods are ineffective, especially since the exhaust duct has a limited exhaust range, resulting in a significant amount of harmful gases remaining untreated in the paint shop. Further improvements are needed in this regard. Summary of the Invention

[0005] The purpose of this application is to provide an oil mist treatment system and method for a paint spraying workshop, which can increase the ventilation range of the paint spraying workshop and effectively reduce harmful gases in the paint spraying workshop.

[0006] This application provides an oil mist treatment system for a paint spraying workshop, which adopts the following technical solution:

[0007] An oil mist treatment system for a paint spraying workshop includes: an exhaust fan installed on one side of the spray booth near the workbench; an oil mist separation device connected to the exhaust fan and used to separate oil mist from the gas inside the exhaust fan; an exhaust duct horizontally installed on the top of the spray booth and having several sets of symmetrical exhaust branch pipes installed on both sides and at the end away from the workbench; a guide device installed at the end of the exhaust branch pipe and the exhaust duct away from the workbench and used to guide the gas in the spray booth towards the workbench; and a blower installed in the spray booth to blow air into the exhaust duct of the exhaust branch pipe.

[0008] By adopting the above technical solution, exhaust ducts and branch exhaust pipes are installed on the top of the spray booth, along with air guide devices and blower devices. When the blower device is turned on, the air guide device can direct the airflow, causing the gas in the spray booth to flow as far as possible toward the workbench. Then, through the installed exhaust device and oil mist separation device, the harmful gases in the spray booth can be treated quickly and extensively, effectively reducing the amount of harmful gases in the spray booth.

[0009] This application further provides that the guiding device includes: an extension plate fixed to the upper edge of the end of the exhaust branch pipe; a guide plate rotatably installed on the side of the extension plate away from the exhaust branch pipe and whose extension direction is perpendicular to the extension direction of the exhaust branch pipe; and a first adjusting member disposed on the extension plate for adjusting the angle of the guide plate.

[0010] By adopting the above technical solution, the air guide plate can guide the air coming out of the exhaust branch pipe, so that the blown air can blow the harmful gases at the edge of the paint booth toward the workbench. The first adjustment component can adjust the angle of the air guide plate, thereby increasing the applicability of the air guide plate.

[0011] This application further includes: sliders slidably disposed on the inner side of the extension plate and the inner side of the air guide plate toward the hinge point of the air guide plate; return springs disposed on the inner sides of the extension plate and the air guide plate for driving the sliders to slide away from the hinge point of the air guide plate; elastic plates rotatably mounted on the corresponding sliders; and a second adjusting member disposed on the extension plate for adjusting the curvature of the elastic plate.

[0012] By adopting the above technical solution, the elastic plate can guide the air coming out of the exhaust branch pipe in advance based on the air guide plate to reduce air resistance. At the same time, the second adjusting component can also adjust the curvature of the elastic plate according to actual needs to adapt to more actual needs.

[0013] This application further provides that: elastic cloth is provided on both sides of the air guide plate and between the exhaust branch pipe for connecting the two.

[0014] By adopting the above technical solution, the elastic cloth can freely expand and contract with the rotation of the air guide plate. At the same time, it can also restrict the air blown out of the exhaust branch pipe from both sides, which can play a role in gathering air.

[0015] This application further provides that: a rotating plate is hinged to the side of the air guide plate away from the hinge point and the bottom edge of the exhaust branch pipe end, and a driving component for driving the rotating plate to rotate is provided on the air guide plate and the exhaust branch pipe.

[0016] By adopting the above technical solution, the rotating plate can not only extend the air guide path of the air guide plate, but also further guide the air direction, so that the air blows more accurately to the predetermined position. The driving component can adjust the angle of the rotating plate according to actual needs to increase the applicability of this application.

[0017] This application further provides that: two exhaust branch pipes are provided on each side of the exhaust duct, wherein the ends of the exhaust branch pipes at the non-ends of the exhaust duct are rotatably installed on the outside of the exhaust duct using corrugated pipes, and an arc plate is provided on the top of the paint spray booth to allow the exhaust branch pipes to rotate around the rotation point. A power component is also provided on the top of the paint spray booth to drive the corresponding exhaust branch pipes to rotate along the arc plate.

[0018] By adopting the above technical solution, setting up an arc-shaped plate and a power component, when needed, the power component can be activated to drive the exhaust branch pipe to slide along the direction of the arc-shaped plate, thereby increasing the air guiding range of the air guide plate. This structural design is ingenious and has obvious effects.

[0019] This application further provides that: the power assembly includes: a servo motor mounted on the top of the paint booth; and a telescopic rod mounted on the output shaft of the servo motor; a movable block for the exhaust branch pipe to slide is slidably disposed on the arc plate, and the end of the telescopic rod away from the servo motor is hinged to the movable block.

[0020] By adopting the above technical solution, when it is necessary to drive the corresponding exhaust branch pipe to rotate, the servo motor can be turned on to drive the telescopic rod to rotate. During the rotation of the telescopic rod, the moving block can be easily driven to slide on the arc plate, thereby driving the corresponding exhaust branch pipe to adjust the angle.

[0021] This application further provides that: a fixed pipe is installed at the end of the exhaust duct away from the workbench, and an exhaust branch pipe away from the workbench is slidably sleeved on the fixed pipe; a first driving member is provided on the outside of the fixed pipe to drive the exhaust branch pipe at the end away from the workbench to slide.

[0022] By adopting the above technical solution, when the first driving component is turned on, the corresponding exhaust branch pipe can be driven to extend and retract on the fixed pipe. This solution can adjust the position of the air guide plate according to the actual situation, thereby increasing the applicable range of the air guide plate and better playing the role of air guiding.

[0023] This application further provides that: a rotating shaft passing through the exhaust branch pipe is installed on the extension plate, a second driving component for driving the rotating shaft to rotate is installed on the exhaust branch pipe, and a telescopic cloth connecting the extension plate and the exhaust branch pipe is provided.

[0024] By adopting the above technical solution, the second driving component can drive the rotating shaft to rotate when needed. When the rotating shaft rotates, it will adjust the corresponding extension plate to rotate, so that the air guide plate can be adjusted in angle at the horizontal position according to the actual situation for better air guidance.

[0025] This application also relates to a method for treating oil mist in a paint shop, comprising the following steps:

[0026] Step 1: When there are workers spraying paint in the spray booth, the exhaust system and oil mist separation device can be turned on.

[0027] Step 2: Turn on the blower to blow air into the exhaust duct and exhaust branch pipes;

[0028] Step 3: Activate the power unit, the first drive unit, and the second drive unit to move the exhaust branch pipe and the air guide plate to the predetermined position.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] By setting up air guide devices and blower devices, when the blower device is turned on, the air guide device can guide the airflow, so that the gas in the spray booth flows as far as possible toward the workbench. Combined with the exhaust device and oil mist separation device, the harmful gases in the spray booth can be quickly reduced.

[0031] By setting up a power unit, a first drive unit, and a second drive unit, the three components work together to effectively increase the working range of the air guide plate and further accelerate the treatment of harmful gases in the paint spraying chamber. Attached Figure Description

Detailed Implementation

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] This application discloses an oil mist treatment system for a paint spraying workshop, such as... Figure 1 and Figure 2 As shown, it includes: a workbench 10 set at a predetermined position inside the spray booth 1, the workbench 10 is used to place the product to be sprayed, and an exhaust device is installed on the side of the spray booth 1 near the workbench 10, with the exhaust end of the exhaust device facing the workbench 10. Considering that there are a lot of harmful gases in the spray booth 1, which need to be treated before being discharged, an oil mist separation device is also installed outside the spray booth 1. The oil mist separation device is connected to the exhaust device. When the exhaust device is turned on, the harmful gases will enter the oil mist separation device in advance for separation, and then be discharged to a predetermined place outside through the pipe of the exhaust device.

[0038] In practice, due to the limited exhaust range of the exhaust device, it can generally only remove harmful gases around the workbench 10 for treatment. In order to guide harmful gases from other locations in the paint spraying chamber 1 to the vicinity of the workbench 10 as much as possible, in this embodiment, an exhaust duct 2 is horizontally installed on the top of the paint spraying chamber 1, and two exhaust branch pipes 21 are installed on both sides of the exhaust duct 2. The connection between one set of exhaust branch pipes 21 and the exhaust duct 2 is located above the workbench 10, and an exhaust branch pipe 21 is also installed at the end of the exhaust duct 2 away from the workbench 10.

[0039] In this system, a guide device is installed at the end of the exhaust branch pipe 21 that is away from the exhaust duct 2. A blower is installed in the spray booth 1. The blower is used to blow air into the exhaust duct 2, so that the air comes out from the end of the exhaust branch pipe 21. At this time, the guide device can guide the air direction, so that the air carries the harmful gas in the spray booth 1 towards the workbench 10. This configuration allows the exhaust device to extract as much harmful gas as possible from the spray booth 1 for treatment.

[0040] In this embodiment, the guiding device includes: an extension plate 22 fixed to the upper edge of the end of the exhaust branch pipe 21, and a guide plate 23 rotatably installed at the end of the extension plate 22 away from the exhaust branch pipe 21. The length direction of the guide plate 23 is perpendicular to the extension direction of the exhaust branch pipe 21. In order to increase the air guiding range of the guide plate 23, a first adjusting member for adjusting the guide plate 23 is also provided on the extension plate 22.

[0041] In this embodiment, the first adjusting component includes: symmetrical protrusions 201 installed on the side of the extension plate 22, and the two sides of the air guide plate 23 are rotatably installed between the protrusions 201 via a connecting shaft. A first servo motor is installed on one of the protrusions 201. The first servo motor is used to drive the connecting shaft to rotate so as to drive the entire air guide plate 23 to rotate. With this design, the harmful gas in the paint spraying chamber 1 can be guided in a certain direction according to actual needs, so that more harmful gas flows towards the vicinity of the workbench 10.

[0042] Considering that in practice, the air coming out of the exhaust branch pipe 21 will blow towards the position between the extension plate 22 and the air guide plate 23, resulting in a relatively large wind resistance loss, in this embodiment, sliders 24 are slidably provided on the inner wall of the extension plate 22 and the inner side of the air guide plate 23. The sliders 24 can slide towards the hinge point of the air guide plate 23. A return spring 25 is also installed on the inner wall of the extension plate 22 and the air guide plate 23. The return spring 25 is used to drive the sliders 24 to return to their original position. In addition, an elastic plate 26 is hinged between the sliders 24. Under normal conditions, the elastic plate 26 is in a bent state. At the same time, a second adjusting member is also provided on the extension plate 22 to adjust the bending degree of the elastic plate 26.

[0043] In this embodiment, the second adjusting member includes a second servo motor installed on the outside of the extension plate 22. A take-up reel 202 is installed on the output shaft of the second servo motor. A pull rope is wound on the take-up reel 202. The end of the pull rope passes through the extension plate 22 and is connected to the side of the elastic plate 26 away from the exhaust branch pipe 21.

[0044] When it is necessary to adjust the curvature of the elastic plate 26, the second servo motor can be turned on to drive the winding wheel 202 to rotate. The rotation of the winding wheel 202 will pull the elastic plate 26 to slide and change the curvature through the pull rope. When the winding wheel 202 winds up the pull rope and causes the elastic plate 26 to bend more, the return spring 25 will be compressed. When the winding wheel 202 releases the pull rope and the elastic plate 26 bends less, the return spring 25 will use its own elastic force to reset the slider 24. Through this design, the air guiding effect of the elastic plate 26 can be adjusted according to the actual situation to minimize wind resistance.

[0045] In this embodiment, in order to reduce the wind blowing away from both sides of the air guide plate 23, an elastic cloth (not shown in the figure) is installed between the two sides of the air guide plate 23 and the exhaust branch pipe 21 to connect the two. The elastic cloth is made of a fabric with good elasticity and does not affect the rotation of the air guide plate 23.

[0046] To further improve the air guiding effect of the air guide plate 23, in this embodiment, a rotating plate 27 is hinged to the side of the air guide plate 23 away from the hinge point and the bottom edge of the exhaust branch pipe 21. A driving component is provided on both the air guide plate 23 and the exhaust branch pipe 21. The driving component is used to drive the rotating plate 27 to rotate. It should be noted that in this embodiment, the specific structure of the driving component is the same as the structure of the first adjusting member, and will not be described in detail here.

[0047] like Figure 1 and Figure 3 As shown, the exhaust branch pipes 21 at both ends of the exhaust duct 2 are corrugated and rotatably installed on the outside of the exhaust duct 2. In addition, an arc plate 3 is installed on the top of the paint spraying chamber 1, and a moving block 33 is installed on the corresponding exhaust duct 2. A power component is also installed on the top of the paint spraying chamber 1. The power component can drive the moving block 33 to slide along the extension direction of the arc plate 3, thereby driving the corresponding exhaust duct 2 to rotate around the hinge point.

[0048] In this embodiment, the power assembly includes a servo motor 31 installed on the top of the spray booth 1. A telescopic rod 32 is installed on the output shaft of the servo motor 31. The end of the telescopic rod 32 away from the servo motor 31 is hinged to the moving block 33. When the servo motor 31 is turned on, the telescopic rod 32 can drive the moving block 33 to rotate the corresponding exhaust branch pipe 21 around the hinge point. The advantage of this setting is that it can further increase the applicable range of the air guide plate 23.

[0049] In this embodiment, a fixed pipe 20 is installed at the end of the exhaust pipe 2 away from the workbench 10, and the exhaust branch pipe 21 away from the workbench 10 is slidably sleeved on the fixed pipe 20. A first driving member is also provided on the outside of the fixed pipe 20. The first driving member can drive the exhaust branch pipe 21 to slide on the fixed pipe 20, thereby changing the extension length of the exhaust branch pipe 21.

[0050] In addition, a rotating shaft 220 passing through the exhaust branch pipe 21 is installed on the top of the extension plate 22. A second driving component is installed on the exhaust branch pipe 21. When the second driving component is turned on, it can drive the rotating shaft 220 to rotate, thereby adjusting the angle of the extension plate 22 and the air guide plate 23. At the same time, in order to prevent air leakage, a telescopic cloth (not shown in the figure) connecting the extension plate 22 and the exhaust branch pipe 21 is also provided. The telescopic cloth is also made of a fabric with good elasticity and will not affect the rotation of the extension plate 22.

[0051] It should be noted that the first driving component in this embodiment can be a common cylinder, and the second driving component can be a common servo motor, which will not be elaborated on here.

[0052] This embodiment also provides a method for treating oil mist in a paint spraying workshop, including the following steps:

[0053] Step 1: When there are workers spraying paint in the spray booth, the exhaust system and oil mist separation device can be turned on.

[0054] Step 2: Turn on the blower to blow air into the exhaust duct 2 and the exhaust branch pipe 21;

[0055] Step 3: Activate the power unit, the first drive unit, and the second drive unit to move the exhaust branch pipe 21 and the air guide plate 23 to the predetermined position.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
