However, this static filtration method has many limitations. In a static environment, the flow of wastewater is relatively poor, and impurities in the wastewater are prone to accumulate on the surface of the filter media, leading to a gradual decrease in filtration efficiency.

[0009] The beneficial effects of this utility model are as follows:
[0010] 1. This utility model, by setting up a water inlet component, rotates the shell and drain blades under the drive of a stepper motor, so that the wastewater forms a dynamic water flow environment inside the shell. The dynamic water flow not only increases the fluidity of the wastewater, but also changes the direction of the wastewater flow, using centrifugal force to gather larger particles of impurities towards the edge of the shell, which is more conducive to the separation of impurities from wastewater. Compared with the traditional static filtration method, this dynamic water flow environment can more thoroughly separate impurities and improve the effect of preliminary filtration.

By setting up a water outlet component, the wastewater filtered by the water inlet component first falls to the outer wall of the water collection shell, and then falls to the top of the filter plate after being filtered again by the water collection shell. During this process, the flow and conversion of wastewater between different components allows impurities in the wastewater to be filtered out when it is subsequently filtered by the filter plate, thereby further improving the overall filtration effect.

[0019] Example:
[0020] Please see Figure 1 - Figure 5 The technical solution provided by this utility model is as follows: a wastewater treatment device for a clean laboratory, comprising: a fixed cylinder 1, a stepper motor 6 fixedly connected to the inner wall of the bottom of the fixed cylinder 1 via a frame, a water baffle 7 fixedly connected to the inner wall of the bottom of the fixed cylinder 1, a water outlet pipe 2 fixedly connected to the outer wall of the bottom of the fixed cylinder 1, and a water inlet pipe 3 fixedly connected to the top of the fixed cylinder 1; a water outlet assembly 5, the bottom of which is fixedly connected to the output end of the stepper motor 6, the water outlet assembly 5 being used to discharge water from inside the fixed cylinder 1 by rotation; and a water inlet assembly 4, the top of which is rotatably connected to the inner wall of the top of the fixed cylinder 1, the water inlet assembly 4 being used to discharge water from inside the fixed cylinder 1 by rotation. The water inlet assembly 4 is used to perform preliminary filtration of wastewater entering the fixed cylinder 1 by rotation. The water inlet assembly 4 includes a spherical shell 41, a rotating shell 45 is fixedly connected to the top of the spherical shell 41, and a drain leaf 44 is fixedly connected to the inner wall of the rotating shell 45. The drain leaf 44 is arranged in a ring along the central axis of the rotating shell 45. A water-blocking block 43 is fixedly connected to the inner wall of the bottom of the spherical shell 41. By rotating the drain leaf 44, the flow direction of the wastewater is changed, thereby increasing the flow of the wastewater. This rotation method creates a dynamic water flow environment for the wastewater in the spherical shell 41, which helps to gather larger particles of impurities in the wastewater to the edge of the spherical shell 41 by centrifugal force.
[0021] The spherical shell 41 has a drainage groove 42 in its wall, and the drainage groove 42 is arranged in a ring along the central axis of the spherical shell 41. The top of the rotating shell 45 is rotatably connected to the inner wall of the top of the fixed cylinder 1. The water outlet assembly 5 includes a filter plate 57. The inner wall of the filter plate 57 is rotatably connected to a rotating shaft 55. The top of the rotating shaft 55 is fixedly connected to a fixed plate 53, and the fixed plate 53 is arranged in a ring along the central axis of the rotating shaft 55. The top of the rotating shaft 55 is rotatably connected to a water collection shell 51 through a connecting shaft 52, and the outer wall of the connecting shaft 52 is rotatably connected to the inside of the water collection shell 51. The wastewater filtered by the water inlet assembly 4 will first fall onto the outer wall of the water collection shell 51, and then be filtered again by the water collection shell 51. The filtered wastewater will then continue to fall onto the top of the filter plate 57.
[0022] The outer wall of the water collecting shell 51 is fixedly connected to the inner wall of the fixed cylinder 1. The inner wall of the fixed cylinder 1 is fixedly connected to the outer wall of the filter plate 57. The bottom of the rotating shaft 55 is fixedly connected to the output end of the stepper motor 6. The top of the connecting shaft 52 is fixedly connected to the bottom of the spherical shell 41.

The outer wall of the brush 54 is slidably connected to the outer wall of the water collection shell 51. The function of the brush 54 is to clean the outer wall of the water collection shell 51 to prevent impurities that may occur during the wastewater treatment process from adhering to the outer wall of the water collection shell 51, which would affect the normal function of the water collection shell 51 and the wastewater treatment effect.
[0023] Working principle:
[0024] When wastewater generated in the laboratory needs to be treated, the wastewater first enters the treatment device through the inlet pipe 3 at the top of the fixed cylinder 1. Here, the inlet component 4 plays an important role in the preliminary filtration of the wastewater.
[0025] The water inlet assembly 4 mainly consists of a spherical shell 41, a rotating shell 45, drainage blades 44, a water-blocking block 43, and a drainage channel 42. After the wastewater enters the spherical shell 41, the water-blocking block 43 is fixedly connected to the inner wall of the bottom of the spherical shell 41, and the wastewater will flow along the outer wall of the water-blocking block 43, thereby dispersing the wastewater to the inner wall of the spherical shell 41. The water inlet assembly 4 is connected to the output end of the stepper motor 6 through the water outlet assembly 5, so that the rotation of the stepper motor 6 drives the water inlet assembly 4 to rotate. The inner wall of the rotating shell 45 is fixedly connected with drainage blades 44 in a ring array. When the rotating shell 45 rotates, the drainage blades 44 rotate synchronously, thereby changing the flow direction of the wastewater and increasing the flow of the wastewater. This rotation method makes the wastewater form a dynamic water flow environment in the spherical shell 41, which helps to gather larger particles of impurities in the wastewater to the edge of the spherical shell 41 through the action of centrifugal force.
[0026] The spherical shell 41 has drainage channels 42 arranged in a ring along its central axis in the wall. After preliminary centrifugal separation, the wastewater enters the interior of the fixed cylinder 1 through these drainage channels 42, thus completing the preliminary filtration process after the wastewater enters the treatment device. Through this preliminary filtration, some larger particulate impurities in the wastewater can be removed, reducing the burden on subsequent treatment stages.
[0027] After initial filtration, the wastewater continues to be treated inside the fixed cylinder 1. At this time, the water outlet assembly 5 starts to work, which is responsible for secondary filtration of the pre-treated wastewater and discharge it from the fixed cylinder 1. The water outlet assembly 5 consists of a filter plate 57, a rotating shaft 55, a fixed plate 53, a water collection shell 51, a connecting shaft 52, a brush 54, and a squeezing blade 56. First, because the output end of the stepper motor 6 is fixedly connected to the bottom of the rotating shaft 55 in the water outlet assembly 5, the stepper motor 6 drives the rotating shaft 55 to rotate. As the rotating shaft 55 rotates, the water inlet assembly 4 connected to its top via the connecting shaft 52 also rotates. The wastewater filtered by the water inlet assembly 4 first falls onto the outer wall of the water collection shell 51, and is then filtered again by the water collection shell 51. The wastewater filtered by the water collection shell 51 continues to fall onto the top of the filter plate 57. At the same time, the outer wall of the rotating shaft 55 is fixedly connected with a ring-shaped array of squeezing blades 56. When the rotating shaft 55 rotates, the squeezing blades 56 also rotate and slide on the top of the filter plate 57. The rotation of the squeezing blades 56 applies a certain pressure to the wastewater on the filter plate 57, causing the wastewater to pass through the filter plate 57 for filtration, further removing fine impurities in the wastewater, making the filtered water purer.
[0028] In addition, a fixed plate 53 arranged in a ring is fixedly connected to the top of the rotating shaft 55. A linear array of brushes 54 is fixedly connected to the outer wall of the fixed plate 53. During the rotation of the fixed plate 53, the brushes 54 will rotate together with the fixed plate 53, and the outer wall of the brushes 54 will slide in connection with the outer wall of the water collection shell 51. The function of the brushes 54 is to clean the outer wall of the water collection shell 51 to prevent impurities that may occur during the wastewater treatment process from adhering to the outer wall of the water collection shell 51, which would affect the normal function of the water collection shell 51 and the effect of wastewater treatment.
[0029] After being filtered by filter plate 57, the water enters the water baffle shell 7 and is finally discharged from the fixed cylinder 1 through the water outlet pipe 2 fixedly connected to the bottom outer wall of the fixed cylinder 1, thus completing the entire wastewater treatment and discharge process.
