DETAILED DESCRIPTION

[0024] The embodiment of the utility model provides a mobile construction site sewage treatment device.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4, including a sewage treatment vehicle 1 and a sludge pump 2, a three-way valve 6 is provided at the water outlet of the sludge pump 2, a guide pipe 7 and a short pipe 8 are fixedly connected between the three-way valve 6 and the sewage treatment vehicle 1, filter screens 11 are fixedly connected on both sides of the sewage treatment vehicle 1, a moving plate 9 is provided between the two filter screens 11, a pressure sensor 10 is fixedly connected inside the moving plate 9, a sewage discharge hole 12 is provided on the side of the two filter screens 11 close to the moving plate 9, and a drainage hole 16 is provided on the side of the two filter screens 11 away from the moving plate 9.

[0026] When the utility model is in use: a sludge pump 2 is fixedly connected to one side of a sewage treatment vehicle 1, and a water inlet end of the sludge pump 2 is fixedly connected to a water inlet pipe 3 for connecting to a sewage pipe on a construction site. After the working sludge pump 2 extracts sewage through the water inlet pipe 3, the sludge pump 2 discharges the sewage through a diversion elbow 5 fixedly connected to the water outlet end, and one end of the diversion elbow 5 is fixedly connected to a three-way valve 6.

[0027] At this time, the normally closed end of the three-way valve 6 is open, and the normally open end is closed, and one end of the guide pipe 7 fixed on the top side of the sewage treatment vehicle 1 is arranged on the side of the normally closed end of the three-way valve 6 and is fixedly connected to the three-way valve 6, such as Figure 2 and Figure 3 As shown, the three-way valve 6 and the guide pipe 7 cooperate to guide the sewage to the right side inside the sewage treatment vehicle 1.

[0028] After the sludge pump 2 has been working for a period of time, a controller 4 is fixedly connected to one side of the sludge pump 2 to work, and the controller 4 is electrically connected to the telescopic pneumatic cylinder 19 and the three-way valve 6. At this time, the controller 4 controls the telescopic pneumatic cylinder 19 to work, and the working telescopic pneumatic cylinder 19 extends and pushes the moving plate 9 to move, so that the moving plate 9 moves to the right (left and right in this application are represented by left and right). Figure 2 As shown in the figure for reference), the moving plate 9 squeezes the sewage through the guide pipe 7 and enters the sewage treatment vehicle 1. After the sewage is pressurized, it is accelerated to contact with the filter screen 11 on the right. The filter screen 11 intercepts impurities in the sewage. The clean water passes through the filter screen 11 and falls to the top of the drainage hole 16 on the right. A water guide pipe 17 is arranged between the left and right drainage holes 16. The water guide pipe 17 fixedly connected to the sewage treatment vehicle 1 guides the clean water. The filtered clean water finally flows out through the outlet pipe 18 fixedly connected to one side of the water guide pipe 17.

[0029] After the telescopic pneumatic cylinder 19 works for a period of time, the controller 4 controls the electrically connected drain valve 13 on the right side to open. At this time, the drain hole 12 on the top of the right drain valve 13 is located between the moving plate 9 and the filter screen 11. After the moving plate 9 moves for a period of time, the sludge in the sewage between the moving plate 9 and the filter screen 11 is discharged through the drain hole 12 and the open drain valve 13. Then the telescopic pneumatic cylinder 19 stops working, and the moving plate 9 temporarily stays on the right side of the sewage treatment vehicle 1.

[0030] While the controller 4 controls the telescopic pneumatic cylinder 19 to work and push the moving plate 9 to move right, the controller 4 controls the electrically connected three-way valve 6 to work, the normally closed end of the three-way valve 6 is closed, the normally open end is opened, and the short pipe 8 set at the normally open end of the three-way valve 6 is fixedly connected to the sewage treatment vehicle 1. At this time, the sewage enters the left side of the interior of the sewage treatment vehicle 1 through the three-way valve 6 and the short pipe 8 set on the top side of the sewage treatment vehicle 1. The pressurized filtration of the sewage by the telescopic pneumatic cylinder 19, the moving plate 9 and the right filter screen 11 will not affect the suction work of the sludge pump 2 on the sewage, thereby ensuring uninterrupted treatment of the sewage, and diverting and discharging the sludge and clean water in the sewage, thereby increasing the speed of iron pipe sewage treatment.

[0031] When the telescopic pneumatic cylinder 19 stops working for a period of time, the controller 4 controls the telescopic pneumatic cylinder 19 to drive the moving plate 9 to move left and reset. At this time, the moving plate 9 and the filter screen 11 set on the left side of the sewage treatment vehicle 1 filter the sewage. At the same time, when the three-way valve 6 works, the sewage enters from the right side of the sewage treatment vehicle 1, and the drainage hole 16 and the water pipe 17 cooperate to discharge the clean water, and the drainage hole 12 and the drainage valve 13 cooperate to discharge the sludge.

[0032] The above work is repeated repeatedly until the sewage treatment is completed.

[0033] One end of the telescopic pneumatic cylinder 19 passes through the filter 11 and the sewage treatment vehicle 1 in sequence and extends to the outside of the sewage treatment vehicle 1 . The telescopic pneumatic cylinder 19 fixedly connected to the sewage treatment vehicle 1 can be simply electrically connected to the controller 4 .

[0034] A sewage valve 13 is provided at the bottom of the two sewage holes 12, and a sewage pipe 14 is fixedly connected between the two sewage valves 13 fixedly connected to the sewage treatment vehicle 1. The sewage pipe 14 collects and drains the sludge discharged through the two sewage valves 13, and finally the sludge is discharged through a mud discharge pipe 15 fixedly connected to one side of the sewage pipe 14.

[0035] A pressure sensor 10 is fixedly connected inside the moving plate 9. The pressure sensor 10 can detect the water pressure inside the sewage treatment vehicle 1. When the sewage treatment vehicle 1 is blocked and cannot discharge sludge or water, and the water pressure detected by the pressure sensor 10 exceeds a preset pressure value, the controller 4 electrically connected to the pressure sensor 10 starts working. At this time, the controller 4 controls the sludge pump 2 and the telescopic pneumatic cylinder 19 to stop working, thereby protecting the sludge pump 2 and the telescopic pneumatic cylinder 19.

[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
