[0023] The through groove 15 can be sealed by the provided sealing plate 16 to separate the upper and lower sides of the partition plate 12 . The upper and lower sides of the partition plate 12 can be connected by pulling out the sealing plate 16 .

[0024] Among them, the stirring mechanism is composed of a motor 11, a rotating shaft 13 and a stirring rod 14. The motor 11 is fixedly connected to the top of the shell 1, and the end of the output shaft of the motor 11 is fixedly connected to the rotating shaft 13.

A plurality of stirring rods 14 are fixedly connected to the side wall of the rotating shaft 13.

[0025] When in use, the motor 11 is started to drive the rotating shaft 13 to rotate, thereby driving the stirring rod 14 to mix the waste liquid and the flocculant.

The filter screen 18 is arranged on the inner wall of the filter frame 7. An inlet and outlet 10 acting on the filter frame 7 is opened on the side wall of the shell 1. A support plate 17 for supporting the filter frame 7 is fixedly connected to the inner wall of the shell 1 below the inlet and outlet 10. The support plate 17 is an annular plate.

[0027] The filter frame 7 and the filter screen 18 are provided to intercept the precipitate produced by the flocculant in the waste liquid, and the inlet and outlet 10 are provided to facilitate the staff to take out the filter frame 7 for cleaning.

[0028] Among them, a connector 8 is fixedly connected to the side wall of the filter frame 7, and the connector 8 is slidably fitted with the inlet and outlet 10.

[0030] Among them, the adjustment mechanism is composed of a lead screw 24, a rotating part 25 and a limit plate 26. The limit plate 26 is fixedly connected to the outer wall of the storage tube 20 through a connecting plate. One end of the limit plate 26 away from the storage tube 20 is rotatably connected to the rotating part 25, and the other end of the limit plate 26 is rotatably connected to the lead screw 24. The lead screw 24 is fixedly connected to the rotating part 25. The end of the lead screw 24 is inserted into the interior of the movable rod 23 and is connected to the movable rod 23 through threaded cooperation. A guide rod 29 is also fixedly connected to the side wall of the limit plate 26, and the other end of the guide rod 29 is slidably inserted into the interior of the movable rod 23.

[0031] The rotating member 25 is rotated to drive the lead screw 24 to rotate, and the movable rod 23 is restricted by the guide rod 29 and cannot rotate. When the lead screw 24 rotates, the movable rod 23 moves along the guide rod 29, so that the position of the movable rod 23 in the storage tube 20 can be controlled.

[0032] An observation port 6 is provided on the side wall of the shell 1 , and a second observation scale 32 is provided on the outer wall of the shell 1 at the side of the observation port 6 .

[0033] The interior of the housing 1 can be observed through the observation port 6 , so that the staff can know the depth of the waste liquid in the housing 1 in real time.

[0034] The utility model provides an acetate production wastewater treatment device, and the specific working principle is as follows:

[0035] When in use, wastewater is introduced into the interior of the housing 1 through the water inlet 2, and then the dosage of the flocculant is added according to the depth of the wastewater. Specifically, the rotating member 25 is rotated to drive the screw 24 to rotate, and the movable rod 23 is restricted by the guide rod 29 and cannot rotate. When the screw 24 rotates, the movable rod 23 moves along the guide rod 29, and the position of the movable rod 23 in the storage tube 20 can be controlled to control the movable rod 23 to move to the right. Figure 4When the movable rod 23 moves to the right to the bottom of the water inlet pipe 22, the No. 2 valve 30 is opened, and the flocculant in the storage box 4 will enter the storage cylinder 20 through the water inlet pipe 22 and fill the storage cylinder 20, and then the No. 2 valve 30 is closed. When it is necessary to adjust the flocculant into the shell 1, the No. 1 valve 28 is opened, and the connecting pipe 21 will have a height higher than the storage cylinder 20, which can ensure that the flocculant in the storage cylinder 20 will not naturally flow into the shell 1 without external interference. The movable rod 23 is controlled to move to the left to squeeze the flocculant in the storage cylinder 20 into the shell 1. The depth of the wastewater can be observed through the observation port 6 and can be read through the No. 2 observation scale 32, and the distance moved by the movable rod 23 can be read through the No. 1 observation scale 31. By ensuring that the distance moved by the movable rod 23 maintains a set ratio with the depth of the wastewater, the dosage of the flocculant added can be ensured to be just right. After the flocculant is added, the motor 11 is started to drive the rotating shaft 13 to rotate, which can drive the stirring rod 14 to mix the wastewater and the flocculant. When the wastewater and the flocculant fully react and produce precipitation, the sealing plate 16 is pulled outward to connect the upper and lower sides of the partition plate 12, and the wastewater will fall to the filter screen 18. The filter screen 18 will intercept the precipitation in the wastewater, and the wastewater will enter the next treatment process. The inlet and outlet 10 provided can facilitate the staff to take out the filter frame 7 for cleaning. The provided connecting piece 8 and the sealing layer 19 can seal the inlet and outlet 10 to prevent the waste liquid inside the shell 1 from flowing out through the inlet and outlet 10.
