[0016] The embodiments of this utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the utility model, and not all embodiments.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar units or units having the same or similar functions throughout.

[0018] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that terms such as "installation", "connection", and "fixing" should be interpreted broadly, and can refer to direct connection, installation or fixing, or indirect connection, installation or fixing, and the present invention does not impose any limitation in this regard.

[0019] like Figures 1 to 2 The diagram shows an embodiment of a spray painting waste collection system of this utility model. It includes a spray booth main body 2, a work platform 1 built inside the spray booth main body 2 for spraying workpieces, and a grid structure for facilitating the falling of waste generated during spraying. A waste trough 6 is provided below the work platform 1 to collect the falling waste. The waste trough 6 is slidably connected to a slide rail 5 to move and switch positions between the work area 21 and the recycling area 22. The waste trough 6 has a top-opening structure for collecting waste. Preferably, the work area 21 and the recycling area 22 are arranged along the length of the slide rail 5. The waste trough 6 and the slide rail 5 are located below the ground, directly below the spray booth main body 2. A top-suction collection hood is provided on the top of the spray booth main body 2 to comprehensively treat the waste gas and residue inside the spray booth.

[0020] In this embodiment, the lower part of the working platform 1 is connected to the collection unit 3, which is located in the working area 21. The collection unit 3 has an opening for waste material to pass through and has a tapered structure to guide the waste material into the waste trough 6. When the workpiece is being sprayed, the waste trough 6 is placed in the working area 21, and the top opening of the waste trough 6 corresponds to the bottom opening of the collection unit 3. Preferably, the collection unit 3 has openings at both the top and bottom and has a tapered structure that is wider at the top and narrower at the bottom, with the area of ​​the lower opening not exceeding the size of the opening of the waste trough 6. The collection unit 3 is made of stainless steel, and the inner surface of the collection unit 3 is treated with an anti-stick coating, which is at least one of electrolytic polishing or Teflon coating. This ensures that the waste residue can smoothly slide into the waste trough 6, allowing the waste gas and waste residue to be concentrated together, facilitating subsequent cleaning, saving cleaning time, and reducing cleaning difficulty.

[0021] In this embodiment, a vibrator 4 is provided on the side wall of the collection section 3. Preferably, the vibrator 4 is a high-frequency vibrator, which promotes the removal of waste residue adhering to the inner wall of the collection section 3 through intermittent vibration. Multiple high-frequency vibrators 4 are connected to the side wall of the collection section 3 and are symmetrically or in an array to ensure uniform force distribution across all parts of the collection section 3. This coordinated arrangement enhances the vibration effect, reduces waste residue adhesion, and minimizes waste accumulation in specific areas, thereby improving the collection rate of waste gas and waste residue. The vibration frequency and amplitude of the vibrator 4 can be adjusted according to the characteristics of the paint type.

[0022] In this embodiment, a sensor 7 is installed in the waste tank 6. The sensor 7 is used to sense the state of the waste and issue a prompt signal when a preset condition is reached. Preferably, the sensor 7 is a weight sensor, used to sense the weight of the waste and issue a prompt signal when a preset threshold is reached. Multiple sensors 7 are evenly distributed at different positions on the bottom of the waste tank 6 to improve the accuracy of weight detection.

[0023] In this embodiment, the work platform 1 includes a platform beam 11, support legs 12, and a grid assembly 10. The platform beam 11 is connected to the main body 2 of the spray booth, the support legs 12 are connected to the platform beam 11 for support, and the grid assembly 10 is connected to the platform beam 11 to form a hollow structure. The connection between the platform beam 11 and the grid assembly 10 ensures the structural rigidity and stability of the work platform 1, provides support for personnel to stand, and also serves as the main load-bearing structure for workpiece spraying. The platform beam 11 is welded from structural steel.

[0024] In this embodiment, the work platform 1 is equipped with guide rails, which are installed on the platform beam 11. The guide rails are used for transporting workpieces or spraying equipment.

[0025] In this embodiment, a removable anti-sticking membrane is laid inside the waste tank 6. The anti-sticking membrane is a polyethylene anti-sticking film, which forms a physical barrier on the surface of the waste tank 6, preventing waste residue and waste materials from contacting the waste tank 6, reducing cleaning difficulty, and facilitating the cleaning of waste residue and waste materials that have been stored for a period of time. If the anti-sticking membrane is laid inside the waste tank 6 and fixed at the edges, when the waste tank 6 needs to process the waste inside, the anti-sticking membrane along with the waste residue and waste materials can be rolled up directly, and then a new anti-sticking membrane can be replaced.

[0026] Preferably, a locking component is provided between the collection section 3 and the waste trough 6. The locking component can remain locked in the working state, reducing the relative displacement of the collection section 3 and the waste trough 6 caused by the operation of the vibrator 4. It can also be unlocked during waste treatment, so that the waste trough 6 can move to the recycling area 22. The specific structure of the locking component and the control method for locking and unlocking are existing technologies, such as the combination of electromagnetic lock and position sensor, etc., which can be flexibly selected based on the general technical knowledge of those skilled in the art. This utility model will not elaborate on them. The drive mechanism for controlling the movement of the waste trough 6 includes a controller 8 and a pneumatic hydraulic rod 9. The controller 8 can be installed according to construction needs. For example, the controller 8 is connected to the main body 2 of the paint booth. The controller 8 is electrically connected to the pneumatic hydraulic rod 9, and the pneumatic hydraulic rod is connected to the slide rail 5. The controller 8 can drive the pneumatic hydraulic rod 9 to work. The pneumatic hydraulic rod 9 uses inert gas as a power source and controls the extension and retraction of its push rod through gas pressure and hydraulic principle. The push rod is connected to the corresponding waste trough 6. By controlling the movement of the waste trough 6 through the pneumatic hydraulic rod 9, the risk of combustion and explosion in the paint booth can be reduced.

[0027] On the other hand, a waste recycling method, based on the above-mentioned spray painting waste collection system, includes the following steps:

[0028] Spraying operation steps: In work area 21, components are sprayed on the work platform 1. Uncoated paint forms waste residue and other debris, which falls into the waste trough 6 below. Specifically, the waste falls through the perforated structure of the work platform 1 into the collection section 3, and is guided by the conical structure of the collection section 3 into the waste trough 6. A high-frequency vibrator 4 installed in the collection section 3 reduces the adhesion of waste to the inner wall of the collection section 3 through intermittent vibration.

[0029] Waste transfer triggering step: When the waste in waste tank 6 reaches the processing condition, a transfer trigger signal is generated and sent to the notification device for notification. In different embodiments, the processing condition can be a preset time elapsed since the last cleaning, or the amount of waste in waste tank 6 reaching a preset threshold. In this embodiment, the weight of the waste in waste tank 6 is monitored in real time by weight sensor 7, and a transfer trigger signal is generated when the amount of waste in waste tank 6 reaches the preset threshold.

[0030] Waste trough 6 transfer steps: In response to the transfer trigger signal, the locking between the collection unit 3 and the waste trough 6 is released, and the air-supported hydraulic rod 9 is activated by the controller 8. The air-supported hydraulic rod 9 pushes the waste trough 6 along the slide rail 5 from the working area 21 to the recycling and processing area 22 to process the waste.

[0031] Waste recycling and processing steps: The waste in the waste tank 6 is recycled and processed in the recycling and processing area 22. In this embodiment, the grid assembly 10 at the cleaning position 221 of the recycling and processing area can be detached or opened, and the waste tank 6 to be processed can be transferred by hoisting equipment, and the anti-sticking membrane in the waste tank 6 can be replaced.

[0032] Reset procedure: When the waste trough 6 is placed back on the slide rail 5 and positioned at the cleaning position 221 in the recycling area, control the pneumatic hydraulic rod 9 to pull the waste trough 6 back to the work area 21 and re-align it with the collection unit 3.

[0033] This invention involves spraying paint onto a workpiece on a work platform 1. Excess paint sprayed from the work platform 1 falls into a collection section 3, and is then collected into a waste tank 6 for centralized processing. It is compatible with different types of paint (water-based paint / solvent-based paint) and workpiece sizes (such as bridge trusses, building steel beams, etc.), solving the problem of difficult cleaning after the work environment becomes polluted, improving the efficiency of treating adhering paint residue, and indirectly reducing the risk of flammability and explosion caused by long-term accumulation of paint mist due to its difficulty in being treated.

[0034] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
