The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0020] Reference herein to "embodiments" means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive of other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] Please refer to Figure 1-4 , an embodiment provided by the present utility model: a waste liquid treatment device for a spray painting booth, including a sedimentation tank 1 and a support frame 2. The sedimentation tank 1 is made of aluminum alloy and is used to fill the waste liquid to be sedimented. A flocculant is added inside the sedimentation tank 1 to accelerate the precipitation of particulate matter. The flocculant is a prior art and will not be elaborated herein. A drain pipe 7 is inserted into the side wall of the sedimentation tank 1, and the drain pipe 7 is communicated with the inside of the sedimentation tank 1. The end of the drain pipe 7 is flange-connected with a butterfly valve 8. Opening the butterfly valve 8 can discharge the wastewater separated by sedimentation through the drain pipe 7. Two sliding grooves 3 are symmetrically opened on the side wall of the sedimentation tank 1 close to the bottom end of the support frame 2. On the side walls of the support frame 2 close to the sliding grooves 3, limit seats 9 are fixedly arranged by welding. The support frame 2 and the limit seats 9 are both made of aluminum alloy and are fixedly connected to form an integral structure. The limit seats 9 are U-shaped and are adapted to the internal dimensions of the sliding grooves 3, facilitating the horizontal sliding of the sliding grooves 3. Rollers 10 are rotatably connected inside the limit seats 9, and the rollers 10 are sequentially connected to roll inside the sliding grooves 3, which can reduce the frictional resistance of the limit seats 9 sliding. A threaded rod 4 is threadedly connected to the middle position at the top end of the support frame 2. The bottom end of the threaded rod 4 is inserted into a return frame 5. The return frame 5 is made of aluminum alloy and is in a shape of a rectangle with a hole in the middle. The end of the return frame 5 is woven with a filter screen 6. The filter screen 6 is made of activated carbon filter cotton and is used to filter suspended impurities. The operator can push the support frame 2 to make the rollers 10 roll horizontally inside the two sliding grooves 3, facilitating the suspended impurities to enter the inside of the filter screen 6 through the return frame 5 for filtering and collection.

[0022] A thread groove 11 is provided at the middle position of the support frame 2 for threaded connection of the threaded rod 4. The thread groove 11 penetrates the support frame 2 and matches the external dimensions of the threaded rod 4. Two hole grooves 12 are symmetrically provided at the surface position of the support frame 2 near the thread groove 11. Both hole grooves 12 are circular and penetrate the support frame 2. Two plug rods 14 are symmetrically fixed at the middle position of the top of the circular frame 5 by welding. The external dimensions of the plug rods 14 are matched with the internal dimensions of the hole groove 12. The plug rods 14 are sequentially inserted into the inside of the hole groove 12 to limit the circular shape. The lateral displacement of the frame 5 improves the stability of the vertical movement of the circular frame 5. A connecting seat 13 is fixedly provided at the middle position of the top of the circular frame 5. A card slot 16 is opened inside the connecting seat 13. The internal rotation connection of the card slot 16 is connected to a limit plate 17. The top of the limit plate 17 is fixedly connected to the bottom end of the threaded rod 4. The top of the threaded rod 4 is fixedly connected to a hand wheel 15. Rotating the hand wheel 15 can drive the threaded rod 4 to rotate vertically inside the threaded groove 11, thereby pushing the connecting seat 13 to move vertically, so as to facilitate the adjustment of the height of the circular frame 5.

[0023] Working principle: When the waste liquid treatment device for a paint spraying room is in use, the operator first pours the waste water into the sedimentation tank 1, and then adds flocculants into the sedimentation tank 1 to accelerate the sedimentation of particles. The flocculants are prior art and will not be described in detail here. When there are suspended impurities on the surface of the waste water, the operator pushes the support frame 2 to make the roller 10 roll horizontally inside the two slide grooves 3, thereby improving the convenience of horizontal movement of the circular frame 5 and the filter screen 6, so that the suspended particles can be collected inside the filter screen 6, thereby further reducing the suspended particles in the waste liquid and improving the quality of waste liquid separation. Secondly, by turning the hand wheel 15, the circular frame 5 and the filter screen 6 can be driven to move vertically, thereby facilitating adaptation to different liquid levels and improving the adaptability of the device. The plug rod 14 can limit the lateral position of the circular frame 5 to improve the stability of the vertical movement. When the suspended particles are removed, the operator opens the butterfly valve 8 to discharge the precipitated waste water from the drain pipe 7.
