[0018] like Figures 1 to 3 As shown,
[0019] A wastewater recycling device in a concrete production process is characterized in that it includes a frame 2, a filter box 3 is fixedly connected to the frame 2, a feed pipe 4 is provided on one side of the upper end of the filter box 3, a support rod 5 is rotatably connected to the filter box 3, two first filter screens 6 are symmetrically provided on the support rod 5, and abutment blocks 7 are slidably penetrated on both sides of the filter box 3, a first push rod motor 8 is fixedly connected on both sides of the filter box 3, a push rod of the first push rod motor 8 is connected to the abutment block 7, and the lower end of the first filter screen 6 can abut on the abutment block 7, a first driving motor 9 is provided on the front side of the filter box 3 to drive the support rod 5 to rotate, a collecting box 10 is slidably connected to the side of the filter box 3 away from the feed pipe 4, a drain hole is provided at the lower end of the collecting box 10, and an outlet pipe 11 is provided at the lower end of the filter box 3.
[0020] In this embodiment, the wastewater generated during the concrete production process enters the filter box 3 through the feed pipe 4 and falls on the first filter screen 6 below the feed pipe 4. The first filter screen 6 filters the sand and gravel in the wastewater, and the filtered water passes through the first filter screen 6 and is discharged from the outlet pipe 11. After the first filter screen 6 on this side has been used for a period of time, the first push rod motor 8 drives the abutment block 7 to move outward until the first filter screen 6 loses its abutment, and then the first drive motor 9 drives the support rod 5 to rotate 180°, and the unused first filter screen 6 rotates to the bottom of the feed pipe 4 and is used. The first filter screen 6 rotates to the top of the collection box 10 and pours the sand and gravel filtered on the surface into the collection box 10. Then the first push rod motor 8 drives the abutment block 7 to move to the lower end of the first filter screen 6 and continue to abut. The first drive motor 9 drives the first filter screen 6 above the collection box 10 to rotate back and forth, so that the end of the first filter screen 6 collides with the abutment block 7, and the sand and gravel blocked on the first filter screen 6 is shaken off into the collection box 10. After being shaken off, it continues to be filtered through the first filter screen 6 on the other side. The sand and gravel collected in the collection box 10 is discharged through the drain hole to drain the wastewater remaining on the sand and gravel. The two first filter screens 6 are used alternately to keep the first filter screen 6 at a good filtering efficiency. The first drive motor 9 drives the support rod 5 and the first filter screen 6 to rotate and collide with the abutment block 7, so that the sand and gravel on the surface of the first filter screen 6 is shaken off into the collection box 10 for collection in time, thereby ensuring the recovery efficiency of wastewater.

A second push rod motor 20 is fixedly connected to the frame 2, and the push rod of the second push rod motor 20 is connected to the upper end of the partition 19. After filtering, the wastewater is discharged from the outlet pipe 11 into the sedimentation tank 14. The flocculant tank 12 feeds flocculant into the sedimentation tank 14 through the feeding pipe 13. The wastewater and the flocculant mix to produce flocs, which will slowly settle to the bottom of the sedimentation tank 14. Then the second push rod motor 20 drives the partition 19 to rise, and the water pump 17 draws the purified water away through the water pumping pipe 16 and discharges it from the drain pipe 18 for subsequent use. The flocs will be blocked by the second filter 15 and will not be sucked into the water pumping pipe 16, thereby improving the purification effect of the wastewater.
