DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution: a waste liquid recovery device for processing environmentally friendly water-based paint as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 . It includes a catalytic mixing structure 1. The catalytic mixing structure 1 includes a first mixing tank 11. The motor on the first mixing tank 11 drives the first stirring assembly 12 to rotate. The first mixing tank 11 is connected to the catalytic liquid storage tank 13 through a first quantitative feeding assembly 15. The motor on the catalytic liquid storage tank 13 drives the second stirring assembly 14 to rotate. The second stirring assembly 14 and the first stirring assembly 12 have the same structure. A water level sensor 16 is embedded in the first mixing tank 11. The first mixing tank 11 is connected to a second drain pipe 17. The first stirring assembly 12 includes a first stirring rod 121, and a scraping plate 122 is fixed on the first stirring rod 121. The first quantitative feeding assembly 15 includes a storage pipe 151. A fixing plate 152 is fixedly connected to the storage pipe 151. The fixing plate 152 adjusts the position of a piston 153 through a telescopic structure. The piston 153 fits the inner wall of the storage pipe 151. The upper side of the storage pipe 151 is connected to a liquid inlet pipe 154. The storage pipe 151 is connected to the first mixing tank 11 through a first drain pipe 155.

[0026] Among them, the first stirring assembly 12 and the second stirring assembly 14 have the same structure. Motors are fixed on both the first mixing tank 11 and the catalytic liquid storage tank 13. The model of the water level sensor 16 is HM21. Electric valves are fixed in both the liquid inlet pipe 154 and the first drain pipe 155.

[0027] Specifically, the telescopic structure in this application is a hydraulic cylinder, and the hydraulic cylinder is a prior art.

[0028] In the above solution, the wastewater enters the first mixing tank 11 through the inlet pipe. The water level sensor 16 in the first mixing tank 11 detects the position of the wastewater. When the wastewater reaches the required position, the liquid inlet is stopped. With the assistance of the motor on the catalyst liquid storage tank 13, the first stirring rod 121 in the catalyst liquid storage tank 13 is driven to rotate. The rotation of the first stirring rod 121 drives the scraper 122 to clean the inner wall of the catalyst liquid storage tank 13, ensuring complete discharge. With the assistance of the hydraulic cylinder on the fixed plate 152, the piston 153 in the storage pipe 151 is driven to move through the hydraulic rod, so as to pump the catalyst liquid in the catalyst liquid storage tank 13 into the storage pipe 151. The electric valve in the liquid inlet pipe 154 is closed, and the electric valve in the first drain pipe 155 is opened. With the assistance of the hydraulic cylinder on the fixed plate 152, the piston 153 is driven to push the catalyst liquid in the storage pipe 151 through the hydraulic rod, and finally the whole pipe of catalyst liquid is added. The catalyst liquid is quantified through the storage pipe 151 as needed, increasing the practicality. With the assistance of the motor on the first mixing tank 11, the first stirring rod 121 is driven to rotate. The rotation of the first stirring rod 121 drives the scraper 122 to stir the first mixing tank 11 and clean the inner wall, ensuring the stirring effect and complete discharge at the same time.

[0029] As Figure 1 , Figure 2 and Figure 3 shown, the catalytic mixing structure 1 is connected to the paint sludge coagulation structure 2. The paint sludge coagulation structure 2 includes a second mixing tank 21. The second mixing tank 21 drives the third stirring assembly 22 to rotate through a motor. A support frame 23 is fixed to the lower side of the second mixing tank 21. A flocculant liquid storage tank 24 and a second quantitative feeding assembly 25 are fixed to the upper side of the second mixing tank 21 by threads. The flocculant liquid storage tank 24 is located on the right side of the second quantitative feeding assembly 25. The third stirring assembly 22 includes a second stirring rod 221. A first scraping plate 222 is fixed to the second stirring rod 221. A guiding screw 223 is fixed to the lower side of the second stirring rod 221. The discharge pipe 224 is connected to the second mixing tank 21;

[0030] Among them, the structures of the second quantitative feeding assembly 25 and the first quantitative feeding assembly 15 are the same. A water level sensor 16 is embedded in the second mixing tank 21. The motor on the flocculant liquid storage tank 24 drives the first stirring assembly 12 on the flocculant liquid storage tank 24 to rotate;

[0031] In the above solution, the flocculant liquid storage tank 24 is stirred and scraped under the assistance of the first stirring assembly 12 on the flocculant liquid storage tank 24 to ensure complete discharge of the flocculant liquid. Under the assistance of the second metering feeding assembly 25, the flocculant liquid is added into the second mixing tank 21 as needed. Under the assistance of the motor on the second mixing tank 21, the second stirring rod 221 is driven to rotate. The rotation of the second stirring rod 221 mixes the internal materials and cleans the inner wall with the assistance of the first scraping plate 222 to ensure later discharge. The flocculant liquid fully reacts with the water-based paint in the wastewater and aggregates into blocks. The wastewater and the paint residue aggregate blocks enter the first water guide pipe 32 through the discharge pipe 224 and are assisted in guiding the materials by the guiding screw 223 to avoid blocking the discharge port.

The lower side of the second filter pipe 33 is connected to the second water guide pipe 35. The motor on the first filter pipe 31 drives the gear set 36 to rotate and drives the screw rod 37 to rotate. The right sides of the second filter pipe 33 and the first filter pipe 31 are both connected to the waste pipe 38. The lower side of the waste pipe 38 is connected to the waste box 39;

[0033] Among them, the mesh densities of the filter nets 34 in the first filter pipe 31 and the second filter pipe 33 are different, so as to ensure the filtering effect. The motor fixed in the waste box 39 drives the crushing roller to rotate, and the rotation of the crushing roller crushes the paint residue aggregation, and the crushed paint residue aggregation waste is stored in the lower pull-out box for convenient later recycling and treatment;

[0034] In the above solution, the treated circulating water and the paint residue aggregation blocks are separated by the filter net 34 on the first filter pipe 31. The separated circulating water enters the second filter pipe 33 through the first water guide pipe 32 and is further treated under the assistance of the filter net 34 in the second filter pipe 33 to ensure the separation quality of the paint residue aggregation blocks. Under the assistance of the motor on the first filter pipe 31, the gear set 36 is driven to rotate. The rotation of the gear set 36 drives the screw rod 37 to rotate, and the rotation of the screw rod 37 drives the paint residue aggregation blocks in the first filter pipe 31 and the second filter pipe 33 to move. Finally, the paint residue aggregation blocks enter the waste box 39 through the waste pipe 38, and the filtered circulating water enters the sedimentation tank 41 through the second water guide pipe 35.

[0035] As Figure 1 and Figure 2As shown in the figure, the lower side of the filtering component 3 is connected to the precipitation component 4. The precipitation component 4 includes a precipitation tank 41. The left side of the precipitation tank 41 is fixedly provided with a motor box 42. The motor in the motor box 42 drives the screw rod 43 to rotate. The rotation of the screw rod 43 drives the slider 44 to slide in the chute opened on the precipitation tank 41. The lower side of the slider 44 is fixedly provided with a second scraping plate 45;

[0036] Among them, the motor in the motor box 42 is a stepping motor. The stepping motor is a prior art. The lower side of the precipitation tank 41 penetrates through the discharge port to ensure complete discharge;

[0037] In the above solution, under the auxiliary action of the stepping motor in the motor box 42 on the precipitation tank 41, the screw rod 43 is driven to rotate. The rotation of the screw rod 43 drives the second scraping plate 45 to move left and right through the slider 44, so as to scrape and discharge the lower side inside the precipitation tank 41.

[0038] Working principle: When using the waste liquid recovery device for processing environmentally friendly water-based paint, connect the external power supply.
