Description
Technical Field
[0001] The present invention relates to the technical field of shield machine sewage treatment, and in particular to a sewage treatment device for a shield machine. Background Art
[0002] Shield machines are widely used in underground construction, particularly in urban subways, tunnels, and underground pipelines. With the acceleration of urbanization and the continued expansion of underground construction, the use of shield machines has also increased. During shield construction, especially in areas with moist soil or abundant aquifers, shield machines require large quantities of slurry as a support and cooling medium. This slurry mixes with soil, water, and other substances during construction, forming wastewater that must be effectively treated to reduce environmental pollution. Therefore, developing efficient and cost-effective wastewater treatment technologies for shield machine wastewater is crucial.
[0003] However, in the existing sewage treatment process for shield machines, the sewage will be mixed with soil and gravel. During the sewage treatment process, not only will the pipes be blocked, but the gravel will also damage the pipes, resulting in relatively poor sewage treatment effect.

[0008] Furthermore: the intermittent rotation mechanism includes a first rotating shaft, a T-shaped support plate, a second rotating shaft, a driving tooth, a linkage tooth, an arc-shaped guide plate, a turntable, a baffle, a groove, a linkage column and a rocker arm, and the first rotating shaft and the second rotating shaft are respectively rotatably connected to the bottom inner wall of the box body, the T-shaped support plate is fixedly connected to the bottom inner wall of the box body between the first rotating shaft and the second rotating shaft, and the top ends of the first rotating shaft and the second rotating shaft are respectively inserted through the top ends of the T-shaped support plate.

[0012] At the same time, the outer circumference of the turntable and the annular guide ring are fixedly connected to each other, and the bottom circumference of the filter screen and the top circumference of the turntable are fixedly connected by bolts.
[0013] As a preferred embodiment of the present invention, the guide assembly includes a guide plate, a spring, an arc-shaped guide plate and a guide pipe, and the guide pipe is fixedly connected to the inside of the inclined seat, and the opposite ends of the guide pipe and the water outlet pipe are fitted and docked with each other.

The sewage falls into the filter screen in four shapes, and the intermittently rotating filter screen can filter the sewage inside. At the same time, the multiple sets of baffles located above the turntable that rotate synchronously can buffer the gravel in the sewage, so that the sludge and gravel in the sewage can be blocked by the filter screen, solving the problem of pipe blockage and damage caused by mud and gravel mixed in the sewage, promoting the effect of sewage treatment, and also facilitating the efficiency and quality of subsequent sewage purification.
[0018] 2.

[0019] 3. This sewage treatment device for a shield machine, when water overflows the inclined seat and enters the outlet pipe, it will accelerate along the slope of the outlet pipe and be blocked by the guide plate. At this time, the cross-section of the sewage passing through becomes smaller, which increases the speed of sewage passing through. The arc-shaped guide plate can be elastically deformed by the spring, thereby realizing the adaptive adjustment function of the sewage passing cross-section. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The arc-shaped guide plates 1006 are fixedly connected to the outer side of the bottom circumference of the rotating disk 1007, and the grooves 1009 are respectively opened on the outer wall of the bottom of the rotating disk 1007 between each two arc-shaped guide plates 1006. The pendulum rod 1011 is connected to the top circumference of the rotating shaft 1001 by means of a thread, and the linkage gear 1005 and the driving gear 1004 are meshed with each other. One end of the pendulum rod 1011 is a fan-shaped structure.
[0038] The outer surface of the fan-shaped structure of the swing rod 1011 is adapted to the inner surface of the arc-shaped guide plate 1006. The linkage column 1010 is connected to the top of the other end of the swing rod 1011 by a thread, and the linkage column 1010 and the groove 1009 are slidably adapted to each other.
