The drainage volume is large and the drainage points are scattered. The accumulation and precipitation of particulate matter in the wastewater during long-distance pipeline gravity transportation can easily cause blockage of the drain pipe. In addition, due to the special environmental requirements of the clean room, the traditional method of unblocking and cleaning the drain pipe can easily cause clean room environmental pollution.

[0005] In a possible implementation, the sedimentation plate is arranged to be gradually inclined from bottom to top toward the water inlet pipe.
[0006] In a possible implementation, a plurality of sedimentation plates are provided at intervals along the spacing direction between the water inlet pipe and the water outlet pipe, and the baffle is connected to the sedimentation plate close to the water inlet pipe.
[0007] In a possible implementation, a water spraying member is horizontally provided through the side wall of the sedimentation box away from the water inlet pipe. The water spraying member extends into the sedimentation box and is located above the baffle plate for spraying water on the baffle plate and the sedimentation plate.
[0008] In a possible implementation, a guide slope is provided on the inner bottom wall of the sedimentation box, and the guide slope gradually extends obliquely upward from a side close to the sewage pipe to a side far from the sewage pipe.

[0012] Compared with the prior art, the suspended particle wastewater sedimentation device for the drainage pipe provided in the present embodiment is that the suspended particle wastewater enters the sedimentation box from the front section pipe through the water inlet pipe, and the water level in the sedimentation box gradually rises. When the water level is higher than the lower edge of the sedimentation plate, the buffering effect of the sedimentation plate and the inner wall of the sedimentation box reduces the fluctuation amplitude of the suspended particle wastewater, and facilitates the sedimentation of particles. Until the water level in the sedimentation box reaches the outlet pipe, the wastewater with removed particles enters the rear section pipe from the outlet pipe (at this time the water level is lower than the first probe). In this process, the particles are at the bottom of the sedimentation box. It accumulates in the form of sludge. When the sludge submerges the lower edge of the sedimentation plate, the space between the sedimentation plate and the side wall of the sedimentation tank connected to the outlet pipe is blocked (the outlet pipe no longer drains water). The water level continues to rise on the side of the sedimentation plate close to the inlet pipe until it submerges the first probe. The level meter gives an alarm, and then the sewage pipe is opened for sewage discharge. The sludge is reduced and no longer submerges the lower edge of the sedimentation plate. During this process, the water level also slowly drops until the liquid level reaches the second probe. The sewage pipe is closed, and the suspended particle wastewater continues to enter and the particles are precipitated at the beginning, and this is repeated. The particles in the suspended particle wastewater in the drain pipe can be precipitated and discharged, which not only avoids the blockage of the drain pipe, but also avoids the environmental pollution of the clean room caused by cleaning the drain pipe.

During its actual use, the suspended particle wastewater enters the sedimentation box 10 from the front section pipe 1 through the water inlet pipe 11, and the water level in the sedimentation box 10 gradually rises. When the water level is higher than the lower edge of the sedimentation plate 20, the buffering effect of the sedimentation plate 20 and the inner wall of the sedimentation box 10 reduces the fluctuation amplitude of the suspended particle wastewater, and facilitates the sedimentation of particles.

When the water level is higher than the lower edge of the sedimentation plate 20, the buffering effect of the sedimentation plate 20 and the inner wall of the sedimentation box 10 reduces the fluctuation amplitude of the suspended particle wastewater, and facilitates the sedimentation of particles, until the water level in the sedimentation box 10 reaches the outlet pipe 12, and the wastewater with particles removed enters the rear section pipe 2 from the outlet pipe 12 (at this time, the water level is lower than the first probe 41). In this process, the particles are formed at the bottom of the sedimentation box 10. Sludge accumulates, and after the sludge submerges the lower edge of the sedimentation plate 20, the space between the sedimentation plate 20 and the side wall of the sedimentation tank 10 connected to the outlet pipe 12 is in a blocked state (the outlet pipe 12 no longer drains water), and the water level continues to rise on the side of the sedimentation plate 20 close to the water inlet pipe 11 until it submerges the first probe 41, and the liquid level meter 40 gives an alarm, and then the sewage pipe 13 is opened for sewage discharge, and the sludge is reduced and no longer submerges the lower edge of the sedimentation plate 20.
