The bottoms of the primary sedimentation tank 1, the secondary sedimentation tank 2 and the drainage tank 3 are provided with a sludge discharging structure 5 for discharging sludge at the bottom of the tank.

That is, when the sand-containing paint is washed, the sand-containing sludge flows into the primary sedimentation tank 1 and gradually fills the primary sedimentation tank 1. After the cleaning is stopped, the sand-containing sewage can automatically settle, clear water is upward, and sludge is settled to the bottom of the tank. When the sand-containing coating is continuously cleaned next time, the excessive water flows into the secondary sedimentation tank 2 from the first water discharge hole 11 until the secondary sedimentation tank 2 is full. The sewage which is not completely precipitated at one time can continue to be precipitated in the secondary sedimentation tank 2, and as the heights of the first water discharge hole 11, the second water discharge hole 21 and the third water discharge hole 31 are sequentially reduced, the liquid in the secondary sedimentation tank 2 can not flow back to the primary sedimentation tank 1, and the supernatant after precipitation can flow from the second water discharge hole 21 of the secondary sedimentation tank 2 to the water discharge tank 3. At this time, the sand and mud are basically deposited, and the sewage flows into the sewer pipe from the third water discharge hole 31 of the water discharge tank 3 after final deposition in the water discharge tank 3, so that the pipe is effectively prevented from being blocked and disconnected. In the present embodiment, the third drain hole 31 is the same height as the bottom surface of the drain tank 3 or slightly higher than the bottom surface of the drain tank 3 to drain the water in the drain tank 3. The silt of the bottoms of the first-stage sedimentation tank 1, the second-stage sedimentation tank 2 and the drainage tank 3 is discharged through the silt discharging structure 5, so that the cleaning is convenient, the manpower resources are effectively saved, and the working progress is accelerated.

Through the arrangement, the whole structure of the sedimentation tank can be more compact, and the occupied space is saved.

Preferably, as shown in fig. 1, the sedimentation tank further comprises a first gate structure 6 and a second gate structure 7. First intercommunication groove 411 is offered along the direction of height on the first baffle 41, and first intercommunication groove 411 can communicate first class sedimentation tank 1 and second grade sedimentation tank 2, and the tank bottom of first intercommunication groove 411 is less than the height of first wash port 11, and first gate structure 6 sets up in first baffle 41, and first gate structure 6 can shutoff first intercommunication groove 411. Correspondingly, a second communicating groove is formed in the second partition plate 42 along the height direction, the second communicating groove can be communicated with the secondary sedimentation tank 2 and the drainage tank 3, the bottom of the second communicating groove is lower than the height of the second drainage hole 21, the second gate structure 7 is arranged on the second partition plate 42, and the second gate structure 7 can seal the second communicating groove.

It will be appreciated that the settling tank requires periodic cleaning of the sewage and sludge to avoid reducing settling efficiency or preventing odor from affecting the laboratory environment. When the sedimentation tank is cleaned, first, the first gate structure 6 and the second gate structure 7 are opened, so that the upper liquid in the primary sedimentation tank 1 and the secondary sedimentation tank 2 flows into the drainage tank 3, flows into the sewer pipe from the third drain hole 31, and then the sewage discharge is completed. And then, sequentially cleaning the sludge at the bottoms of the primary sedimentation tank 1, the secondary sedimentation tank 2 and the drainage tank 3 through the sludge discharging structure 5 so as to complete the whole cleaning work of the sedimentation tank.

Since the structure and function of the second gate structure 7 are the same as those of the first gate structure 6, only the first gate structure 6 will be specifically described below, and the second gate structure 7 is the same as the first gate structure 6.

In the present embodiment, the distance between the first closing plate 611 and the first limiting plate 613 is equal to the thickness of the first partition 41, so as to ensure a close fit between the first closing plate 611 and the first partition 41 when the first partition 41 is inserted into the first limiting space.

Preferably, the first sealing plate 611 is provided with a first gasket on a side facing the first partition 41; the first limiting plate 613 is provided with a second gasket on a side facing the first partition 41. The arrangement of the first sealing gasket and the second sealing gasket can ensure the tightness between the first blocking piece 61 and the first partition 41 and prevent water seepage between the primary sedimentation tank 1 and the secondary sedimentation tank 2.

More specifically, the first shutter structure 6 further includes a first connecting shaft 62. The first connecting shaft 62 is horizontally disposed and is connected to the first partition 41 at intervals.

In this embodiment, the moving distance of the first connecting shaft 62 in the first chute is greater than the height of the first limiting space, and when the first blocking member 61 moves to the position where the first partition 41 is separated from the first limiting space, the first sealing plate 611 can also rotate around the first connecting shaft 62, so that the primary sedimentation tank 1 and the secondary sedimentation tank 2 are communicated.

That is, when the sedimentation tank needs to be cleaned, the first blocking member 61 is lifted upwards until the first partition 41 is separated from the first limiting space; then, the first sealing plate 611 is far away from the first communicating slot 411 by rotating the first sealing member 61 around the first connecting shaft 62 in a direction far away from the first partition 41, so that the primary sedimentation tank 1 and the secondary sedimentation tank 2 are communicated, and water at the upper part of the primary sedimentation tank 1 flows into the secondary sedimentation tank 2.

Correspondingly, the second gate structure 7 comprises a second blocking piece, the width of the second blocking piece is larger than that of the second communicating groove, and the second blocking piece is abutted against the second partition plate 42 and can block the second communicating groove.

That is, when the sedimentation tank needs to be cleaned, the second blocking member is lifted upwards first until the second partition plate 42 is separated from the second limiting space; then, the second sealing plate can be far away from the second communication groove by rotating the second sealing piece around the second connecting axial direction far away from the second partition plate 42, and the second sedimentation tank 2 and the drainage tank 3 are communicated. The water at the upper part of the secondary sedimentation tank 2 flows into the drainage tank 3 and finally flows into the sewer pipe through the third drain hole 31 at the bottom of the drainage tank 3. Effectively avoiding the complicated operation and risk of scattering the supernatant by transferring the supernatant with the ladle each time of dredging.

The cabinet body 8 front side articulates there are two cabinet doors 81, and during daily use, row's silt structure 5 is located cabinet body 8, and the aesthetic property is good. When the sludge in the sedimentation tank needs to be cleaned, the cabinet door 81 is rotated to open, so that the sludge discharging structure 5 can be exposed, as shown in fig. 2. The bottom of the sludge discharge pipe 51 is spaced 40-50cm from the bottom surface of the cabinet 8 so that a sludge drum is placed at the bottom of the sludge discharge pipe 51 to hold sludge when discharging sludge.

Still more specifically, the sludge discharging structure 5 further includes a sealing cover 52, and the sealing cover 52 is detachably connected to the sludge discharging pipe 51. In this embodiment, the sealing cap 52 is screwed to the bottom of the sludge discharge pipe 51 to prevent sludge from flowing out of the sludge discharge pipe 51 during daily use, thereby polluting the environment. When the sedimentation tank is cleaned, the sealing cover 52 is screwed to separate the sedimentation tank from the sludge discharge pipe 51, so that sludge at the bottom of the sedimentation tank can be shoveled into the sludge discharge hole through the shovel blade and discharged through the sludge discharge pipe 51.
