Description

Technical Field

[0001] This utility model relates to the technical field of organic waste gas recovery, specifically to an organic waste gas collection and disposal device for a ship painting robot. Background Technology

[0002] During navigation, ships face wind, waves, sun, rain, and high-salinity air environments, all of which are highly corrosive to metals. Painting protects the hull and its machinery and piping from rust, ensuring the proper functioning of equipment and systems. However, painting fumes typically require collection and treatment because they may contain harmful volatile organic compounds (VOCs) and other pollutants. These fumes pose potential hazards to the environment and human health.

[0003] Existing ship painting processes generally employ waste gas recovery devices to adsorb and separate volatile organic compounds (VOCs) and other toxic substances from pollutants. When membrane separation technology is used, some harmful substances in the organic waste gas are separated by using a separation membrane. However, if the separation within the membrane is not timely, some impurities in the gas will not be separated out, and external organic waste gas will re-enter, resulting in incomplete separation of pollutants in the organic waste gas and causing the separated gas to fail to meet emission standards. Utility Model Content

[0004] The purpose of this invention is to provide an organic waste gas collection and treatment device for ship painting robots, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for collecting and disposing of organic waste gas from a ship painting robot includes a main frame and a paint support fixedly installed on the main frame, wherein a separation tank is fixedly installed on the paint support.

[0007] The air inlet end of the separator is equipped with an elastic sealing element;

[0008] The elastic sealing component includes a limiting plate and an elastic moving structure disposed at the air inlet end. A gap is formed between the limiting plate and the elastic moving structure. When the concentration in the separation tank exceeds a threshold, the elastic moving structure moves toward the limiting plate to seal the air inlet end.

[0009] The organic waste gas collection and treatment device for the ship painting robot described above: the limiting plate has an inclined contact surface.

[0010] The organic waste gas collection and treatment device for the ship painting robot described above: a connecting ring is fixedly installed inside the separation tank, and the connecting ring is arranged along the axial direction of the separation tank. Multiple locking blocks are distributed circumferentially on the inner ring of the connecting ring.

[0011] The organic waste gas collection and treatment device for ship painting robots as described above: the elastic sealing member includes a sealing disc that is slidably connected to the connecting ring, and a pressing surface adapted to the contact surface is formed on one end of the sealing disc facing the limiting disc;

[0012] It also includes a spring, one end of which abuts against the sealing disc, and the other end of which abuts against the compression ring fixedly disposed at the air inlet end.

[0013] The organic waste gas collection and treatment device for ship painting robots as described above: a membrane separation component and activated carbon are sequentially arranged in the separation tank along the gas flow direction.

[0014] The organic waste gas collection and treatment device for the ship painting robot described above: the outlet of the separation tank is connected to the inside of the air box fixedly installed on the paint support, the air box is equipped with a fan assembly, and the fan assembly is driven by a motor fixedly installed outside the air box.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] By monitoring the changes in the concentration of organic waste gas inside the separator, and with the cooperation of the elastic moving structure and the fan assembly, when the concentration of organic waste gas inside the separator exceeds the preset threshold, the elastic moving structure is driven to move towards the limiting plate, so that the elastic moving structure abuts against the limiting plate and maintains surface contact. At the same time, the fan assembly stops working to seal the air inlet of the separator, ensuring that most of the toxic substances in the organic gas inside the separator are separated, and the treated gas can be discharged in compliance with standards.

The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0028] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0029] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0030] Please see Figures 1 to 7In this embodiment of the utility model, an organic waste gas collection and disposal device for a ship painting robot includes a main frame 1, a paint support 2, a separation tank 6, a limiting plate 16, and an elastic moving structure.

[0031] For details, please refer to the following: Figure 1 , Figure 2 , Figure 4 and Figure 5 ,include:

[0032] The main frame 1 and the paint bracket 2 fixedly installed on the main frame 1, and the separation tank 6 fixedly installed on the paint bracket 2;

[0033] The air inlet end of the separator 6 is provided with an elastic sealing element;

[0034] The elastic sealing component includes a limiting disk 16 disposed at the air inlet end and an elastic moving structure. A gap is formed between the limiting disk 16 and the elastic moving structure. When the concentration in the separation tank 6 exceeds a threshold, the elastic moving structure moves toward the limiting disk 16 to seal the air inlet end.

[0035] In detail, in this embodiment, the organic waste gas collection and treatment device for the ship painting robot described in this utility model is used. During use, by changing the concentration of organic waste gas in the separation tank 6, and in conjunction with the elastic moving structure, when the concentration of organic waste gas in the separation tank 6 exceeds the preset threshold, the elastic moving structure is driven to move towards the limiting plate 16, so that the elastic moving structure abuts against the limiting plate 16 and maintains surface contact, thereby achieving the sealing of the air inlet end of the separation tank 6, ensuring that most of the toxic substances in the organic gas in the separation tank 6 are separated, and the treated gas can be discharged in compliance with standards.

[0036] Preferably, the limiting disk 16 has an inclined abutment surface 1601.

[0037] For further solutions to this utility model, please refer to [link / reference]. Figure 5 and Figure 6 A connecting ring 18 is fixedly installed inside the separation tank 6, and the connecting ring 18 is arranged along the axial direction of the separation tank 6. Multiple 1801 locking blocks that limit the sealing disc 17 are distributed along the circumference of the inner ring of the connecting ring 18.

[0038] The elastic sealing member includes a sealing disc 17 that is slidably connected to the connecting ring 18. The sealing disc 17 has a pressing surface 1702 that is adapted to the contact surface 1601 on one end facing the limiting disc 16.

[0039] It also includes a spring 15, one end of which abuts against the sealing disc 17, and the other end of which abuts against the compression ring 14 fixedly disposed at the air inlet end.

[0040] Preferably, at least one set of grooves 1802 are formed on the connecting ring 18, and a slider 1701 that slides in cooperation with the grooves 1802 is provided on the sealing disc 17.

[0041] In the initial state, the spring 15 is in a compressed state, so that when the gas enters the separator 6 and the pressure increases, it does not affect the position of the sealing plate 17. Only when the separation efficiency in the separator 6 decreases and the separation is insufficient, and the gas concentration in the separator 6 exceeds the maximum gas concentration that can be separated in the separator 6, the spring 15 is compressed again to meet the need for the sealing plate 17 to move.

[0042] In detail, when the gas concentration in the separator 6 exceeds the preset threshold, the pressure inside the separator 6 increases, which squeezes the sealing plate 17. At this time, the sealing plate 17 moves relative to the connecting ring 18, and the spring 15 continues to be compressed, which reduces the gap between the sealing plate 17 and the limiting plate 16 until the squeezing surface 1702 on the sealing plate 17 abuts against the contact surface 1601 on the limiting plate 16 and maintains surface contact, so as to seal the gas inlet of the separator 6, ensuring that most of the toxic substances in the organic waste gas in the separator 6 are separated, thereby improving the separation efficiency of organic waste gas recovery.

[0043] Preferably, the two ends of the separator 6 are detachably equipped with a first cover plate 601 and a second cover plate 602. The first cover plate 601 and the second cover plate 602 are respectively provided with an air inlet and an air outlet. A one-way valve is provided in both the air inlet and the air outlet, and the elastic sealing element is provided at the end near the first cover plate 601.

[0044] It should be noted that: the separator tank 6 is provided with an exhaust port 603, and a one-way valve is provided in the exhaust port 603, so that the gas separated in the separator tank 6 can be discharged from the exhaust port 603, preventing outside air from entering the separator tank 6 through the exhaust port 603.

[0045] Preferably, a membrane separation component 12 and activated carbon 13 are sequentially arranged inside the separation tank 6 along the gas flow direction. Through the combined action of the membrane separation component 12 and activated carbon 13, the separation efficiency of organic waste gas is further improved.

[0046] For further solutions to this utility model, please refer to [link / reference]. Figure 3 and Figure 7 The air outlet of the separator 6 is connected to the inside of the air box 9 fixedly installed on the paint bracket 2. The air box 9 is equipped with a fan assembly 11, and the fan assembly 11 is driven by a motor 10 fixedly installed outside the air box 9.

[0047] A contact sensor 19 is provided on one end of the limiting plate 16 facing the sealing plate 17, and the contact sensor 19 establishes communication with the motor 10.

[0048] Specifically, when the sealing disc 17 and the limiting disc 16 are fully abutted, the air inlet of the separator 6 is completely blocked. At the same time, the sealing disc 17 squeezes the contact sensor 19. After being touched by the sealing disc 17, the contact sensor 19 sends a signal to the motor 10. After receiving the signal sent by the contact sensor 19, the control panel of the motor 10 controls the motor 10 to stop working, ensuring that most of the toxic substances in the organic waste gas in the separator 6 are separated. After the gas concentration in the separator 6 decreases, the sealing disc 17 separates from the limiting disc 16 under the action of the spring 15, allowing the air inlet of the separator 6 to enter normally while the motor 10 restarts.

[0049] Please see Figure 2 One end of the paint support 2 is connected to a gun head 3. The discharge end of the gun head 3 is wrapped in a collection cover 4 that is fixedly connected to the main frame 1. The collection cover 4 is connected to the separation tank 6 through a conduit 5.

[0050] Preferably, a support plate 7 is fixedly installed on the paint bracket 2, wherein the air box 9 is fixedly connected to the support plate 7, and the separation tank 6 is fixedly connected to the support plate 7 through a ring hoop 8.

[0051] When the nozzle 3 is spraying paint on the ship's surface, the fan assembly 11 operates synchronously to create a negative pressure adsorption force. Paint mist, VOCs and other organic waste gas pollutants are collected through the collection hood 4 and transported to the separation tank 6 through the conduit 5 for separation and treatment. The membrane separation assembly 12 and activated carbon 13 in the separation tank 6 can effectively adsorb and treat paint mist, particulate matter, VOCs and other pollutants. The treated gas can meet the emission standards.
