As shown in Figure 1-4, a sewage settling device for cleaning concrete laboratory equipment includes a primary settling tank 1, a secondary settling tank 2 and a drainage tank between the primary settling tank 1 and the secondary settling tank 2 3. A drainage pipe 1a is provided on the primary settling tank 1, and a drain hole 2a is provided on the secondary settling tank 2. The water in the primary settling tank 1 is discharged into the drainage tank 3 by the drain pipe 1a after the initial settlement. Then it flows into the secondary settling tank 2 through the drainage tank 3 for secondary settlement, and the clear water obtained after the secondary settlement flows out through the drain hole 2a.

The concrete laboratory equipment cleaning sewage settling device provided in the above embodiment adopts the secondary settlement method to settle the sewage. When cleaning the slurry mixer, mortar mixer and other accessories with a tap, tap water with cement slurry or mortar flows into First-level settling tank 1. At this time, even if the settled cement slurry at the bottom of the first-level settling tank 1 is disturbed and turbid again by the water flow, the sewage with slurry will not directly flow into the sewer to cause blockage, but will be discharged through the drain pipe 1a to In the drainage tank 3, then flow into the secondary settling tank 2 by the drainage tank 3, because the cement paste and silt settle again in the secondary settling tank 2, so the water discharged from the secondary settling tank 2 drain hole 2a is relatively small Clear, there will be no problem of clogging the sewer.

As a more optimal solution on the basis of the above-mentioned embodiments, the front end of the drain pipe 1a is provided with a first filter cover (the first filter cover is not shown in the drawings), and the end of the drainage tank 3 is provided with a filter insert. A filter screen plate 4 is arranged in the above-mentioned filter screen slot, a water outlet conduit is arranged in the drain hole 2a, and a second filter cover is provided at the front end of the water outlet conduit (the water outlet conduit and the second filter cover are not shown in the accompanying drawings) ).

In the above-mentioned preferred embodiment, since the front end of the drain pipe 1a is provided with a first filter cover, it is avoided that some floating debris (cigarette butts, paper towels, etc.) discarded by laboratory workers and other personnel in the laboratory enter the drain pipe, resulting in The problem of clogged drains. Because the above-mentioned embodiment is provided with screen plate 4 at the end of drainage tank 3, when cleaning concrete equipment (concrete machine equipment is placed in the equipment installation area as shown in Figure 1), screen plate 4 can filter stones, only makes Sand and cement slurry flow into the secondary settling tank, which can not only recycle the stones, but also solve the problem that the stones enter the secondary settling tank and occupy space, and the secondary settling tank needs to be cleaned frequently. And setting the second filter cover at the front end of the water outlet conduit can further reduce the possibility of sand and gravel entering the sewer, further avoiding the problem of sewer blockage.

More preferably, the drainage groove 3 is a square groove arranged obliquely downward, and the angle between the bottom surface of the square groove and the horizontal plane is 1 degree. Since the drainage tank 3 is arranged obliquely downward, the sand and gravel move towards the secondary settling tank under the action of its own gravity and water flow, so that the situation of sand and gravel accumulating in the tank and blocking the drainage tank 3 can be avoided to a certain extent.

Further, there is a bevel 3a at the junction of the bottom surface of the drainage tank 3 and the secondary settling tank 2, and the corners at both ends of the above-mentioned bevel angle 3a are rounded, and the angle between the bevel 3a and the bottom surface of the drainage tank 3 is 30 degrees, the projected length of the bevel 3a on the horizontal plane is 100mm, and the radius of the rounded corners at both ends of the bevel 3a is 30mm.

By chamfering the angle 3a at the connection between the drainage tank 3 and the secondary settling tank 2, and rounding the corners at both ends of the angle 3a, the sewage for cleaning the concrete mixer and other equipment flows through the filter plate 4 to play a preliminary deceleration effect At the same time, the smooth chamfer setting at the junction of the drainage tank 3 and the secondary settling tank 2 plays a buffering role in the water flow, avoiding excessive water flow directly into the secondary settling tank, and preventing the existing sediment in the secondary settling tank from becoming turbid and blocking the sewer.

Preferably, the filter screen slot is a square groove located on both sides of the drainage tank 3 and the bottom of the tank, and the filter screen plate 4 includes a plate frame 4a made of stainless steel square and a stainless steel filter screen 4b fixedly connected to the plate frame 4a , The plate frame 4a is inserted into the square groove, and the stainless steel filter screen 4b is woven from a stainless steel wire with a diameter of 1mm. The above-mentioned filter screen plate 4 is simple in structure and low in cost. By opening square grooves on both side walls and the bottom of the drainage groove 3, the plate frame 4a can be inserted into the square groove and fixed. When the filter screen plate 4 needs to be replaced, just Just pull out the plate frame 4a from the square groove, and the operation is very simple.

Further, the first filter cover and the stainless steel filter screen 4b are provided with a square filter hole of 4.75 × 4.75mm, and the second filter cover is provided with a square filter hole of 2.36 × 2.36mm. The first filter cover and the filter holes on the stainless steel filter 4b first filter out the larger particles of sand and gravel, and the second filter cover filters out the smaller particles of sand and gravel. Through multi-stage filtration, the influx of sand and gravel into the sewer is completely avoided. , resulting in clogged sewers.

More preferably, the primary settling tank 1 is located above the ground, and the secondary settling tank 2 is located below the ground. The secondary settling tank 2 is realized by digging a pit on the ground. The secondary settling tank 2 is provided with a cover plate, and the drainage tank 3 The width is 300mm. The secondary settling tank 2 is realized by digging holes on the ground, which can reduce the construction cost of the entire settling device and is more conducive to saving space. The cover plate on the secondary settling tank 2 can better ensure the safety of laboratory workers. The purpose of setting the width of 3 to 300mm is to prevent the cleaning sewage in the equipment installation area from rushing through the drainage tank 3 and enter the test area, and it is also convenient to use common shovels on the market to remove the sediment in the drainage tank 3.

The above-mentioned embodiment is a preferred implementation of the utility model. In addition, the utility model can also be realized in other ways. Any obvious replacement is within the scope of protection of the utility model without departing from the concept of the technical solution. Inside.
