[0027] See also Figures 1 to 6The utility model provides a technical solution: a treatment device for recycling polishing waste water, comprising: a pool body 1, three transverse partitions 2 are evenly fixedly installed at the inner end of the pool body 1, and the pool body 1 is divided into a collecting chamber, a reaction chamber, a filtering chamber and a clean water chamber from right to left in sequence. An outlet pipe 7 is fixedly installed on the side wall of the lower end of the transverse partition 2, and the outlet pipe 7 runs through the left and right end side walls of the transverse partition 2. An electric valve is installed on the outlet pipe 7, and water in the upper water chamber can be discharged into the lower water tank by opening the electric valve. A drain pipe 6 is fixedly installed on the side wall on the lower side of one end of the pool body 1, and the inner end of the drain pipe 6 is connected to the clean water chamber, and a valve is installed on the drain pipe 6. By opening the valve, the clean water in the clean water chamber can be discharged for recycling. An extension wall 3 is fixedly installed on the upper end of the collecting chamber, and an overflow trough 4 is arranged on the side of the extension wall 3 close to the reaction chamber. The polishing waste water is discharged into the collecting chamber through the pipeline, and when the waste water in the collecting chamber becomes more, it will enter the reaction tank through the overflow trough 4.

[0028] A vertical partition 5 is fixedly installed on the inner wall of one end of the filter chamber, a filter component is installed in the filter chamber, and a sedimentation tank 8 is opened on the side of the lower end of the filter chamber close to the clean water chamber to precipitate the filtered wastewater and further increase the filtering effect of the wastewater.

[0029] The filtering components include multiple groups of mounting frames 9, multiple groups of threaded rods 11 and multiple driving motors 15. The multiple groups of mounting frames 9 are evenly and fixedly installed between the vertical partition 5 and the pool body 1. A plug-in groove 10 is opened at the upper end of the mounting frame 9. The filter net is inserted into the plug-in groove 10, and the filter net can be installed in the mounting frame 9, and the filter net can filter the wastewater.

[0030] Each group of threaded rods 11 is provided with four, which are distributed on the four sides of the outer end of the mounting frame 9. The threaded rods 11 rotate in the pool body 1 and on the vertical partition 5 through sealed bearings. Cleaning brushes 12 are provided on the left and right sides of each group of threaded rods 11. The upper and lower ends of the handle of the cleaning brush 12 are threadedly connected to the two threaded rods on the same side. The bristles of the cleaning brush 12 are in contact with the outer wall of the filter screen, and the filter screen can be cleaned when the cleaning brush 12 is moved.

[0031] A sprocket 13 is fixedly installed on the outer wall of one end of each group of threaded rods 11, and a chain 14 is transmission-connected on the outer walls of the four sprockets 13. When one of the threaded rods 11 rotates, the four threaded rods 11 can be driven to rotate synchronously, thereby driving the cleaning brush 12 to move. Multiple driving motors 15 are fixedly installed on the outer wall of one end of the pool body 1, and one end of one of the threaded rods 11 in each group is fixedly connected to the output end of the driving motor 15 through a coupling. The driving motor 15 can rotate forward and reverse, and the driving motor 15 can drive the threaded rod 11 to rotate forward and reverse, thereby driving the cleaning brush 12 to reciprocate on the threaded rod 11 to clean the filter.

[0032] When the filter does not need to be cleaned, the cleaning brush 12 is located on one side of the mounting frame 9. After the filter has been used for a period of time, the drive motor 15 can be started to drive the threaded rod 11 to rotate forward and reverse, thereby driving the cleaning brush 12 to reciprocate on the threaded rod 11 to clean the filter and improve the filtering efficiency of the filter.

[0033] By integrating the equipment, the floor space is reduced and the cost is saved. The pool body 1 is made of PP polypropylene material, which has a good anti-corrosion effect. The treatment process adopts the physical and chemical treatment method of "collection + reaction + multi-layer filtration". The start and stop working state can be switched according to the production conditions without affecting the use effect. At the same time, the polishing water is reused, which can greatly save water resources. At the same time, due to the recycling, there is no need to discharge wastewater to the sewage treatment station, which reduces the treatment cost of the sewage treatment station and reduces the operating load.

[0034] After being temporarily stored and collected, the polishing wastewater overflows into the reaction chamber, where it reacts quickly by adding reagents. The reacted particles are intercepted by the next-level filtering components, and the clean water enters the clean water circulation box. The multi-layer screening combined filtration device has good treatment effect, less maintenance frequency after interception, and the effluent can meet the water quality requirements for recycling.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
