Detailed Description
In order to explain the technical content, structural features, and achieved objects and effects of the present invention in detail, the following detailed description is made with reference to the accompanying drawings in combination with the embodiments.
Example one
As shown in fig. 1, an embodiment of the present invention is disclosed for an extraction well for landfill remediation. The suction well comprises a well body 101, a plurality of suction holes 102, a brush head 103 and a lifting mechanism 104. The well body 101 is a hollow pipe, and the top of the well body 101 is connected with a suction pump (not shown) through a flange, and the suction pump is used for providing negative pressure for the inside of the well body 101. The plurality of pumping holes 102 are opened on the pipe wall of the well body 101, and preferably, the plurality of pumping holes 102 are distributed on the pipe wall of the well body 101 in a staggered manner. The brush head 103 is arranged in the well body 101, and the lifting mechanism 104 drives the brush head 103 to move up and down along the axis of the well body 101. The outer edge of the brush head 103 is in contact with the inner pipe wall of the well body 101, i.e. the diameter of the brush head 103 is slightly larger than the pipe diameter of the well body 101, so that the brush head 103 can be fully contacted with the inner pipe wall of the well body 101 when moving up and down, and the suction holes 102 on the pipe wall of the well body 101 can be better cleaned.
In this embodiment, the lifting mechanism 104 comprises a cord 1041 and a driver 1042, one end of the cord 1041 is connected to the driver 1042, and the other end of the cord 1041 is connected to the brush head 103. The driver 1042 can be a motor, and a rotating shaft of the motor is connected to the rope 1041, when the motor rotates forward, the rope 1041 is wound around the rotating shaft of the motor to drive the brush head 103 to move upward, and when the motor rotates backward, the rope 1041 is released from the rotating shaft of the motor to drive the brush head 103 to move downward. It is understood that in other embodiments, other drivers 1042 that enable the reeling in and reeling out of the line 1041 may be used.
Because the brush head 103 is in contact with the wall of the well 101, there is a friction force, and in order to make the brush head 103 move down more smoothly, in this embodiment, an elastic member 105 is disposed between the brush head 103 and the bottom of the well 101, and the elastic member 105 may be a spring or a bellows. The resilient member 105 can provide a guiding action as the brush head 103 moves up and down. In addition, when liquid (such as leachate, rainwater, cleaning liquid, etc.) accumulates in the well body 101, the elastic element 105 can also prevent the brush head 103 from moving down to the lowest position due to the buoyancy of the liquid.
When the brush head 103 is driven by the lifting mechanism 104 to move down to the lowest position, the top of the brush head 103 is located below the plurality of suction holes 102. This arrangement effectively prevents the suction holes 102 from being clogged when the brush head 103 is in an idle state.
In this embodiment, by configuring the liquid injection pipeline 106 for the well 101, when the brush head 103 moves up and down, cleaning liquid is supplied to the plurality of air suction holes 102, so as to further improve the cleaning effect of the air suction holes 102. Referring to fig. 1, the liquid injection line 106 has a liquid inlet 1061 and a liquid injection port 1062, the liquid injection port 1062 is located inside the well 101, and supplies a cleaning liquid to the liquid injection port 1062 through the liquid inlet 1061 for cleaning the plurality of suction holes 102. The liquid inlet 1061 may be connected to an external liquid supply device such as a reservoir, and the cleaning liquid may be water. Preferably, the injection port 1062 may be configured with the nozzle 10 to spray the cleaning fluid more uniformly onto the inner wall of the well 101 for better cleaning the blockage inside the pumping hole 102.
A pump 107 is further disposed at the bottom of the well 101 for discharging the liquid inside the well 101 to the outside of the well 101, for example, after the suction hole 102 is cleaned, the cleaning liquid supplied from the liquid injection line 106 can be discharged to the outside of the well 101 through the pump 107. In the present embodiment, the pump 107 discharges the liquid inside the well 101 to the outside of the well 101 through the independently provided drainage line 108.

Referring to FIG. 2, the liquid injection line 106 has a liquid injection port 1062, a liquid inlet port 1061, and a liquid outlet port 1063. The liquid outlet of the pump 107 is connected to one end of the liquid injection line 106, the other end of the liquid injection line 106 is connected to the liquid inlet 1061 and the liquid outlet 1063 by the first three-way valve 1064, and the liquid injection port 1062 and the liquid outlet of the pump 107 are connected to the middle of the liquid injection line 106 by the second three-way valve 1065.
In this embodiment, the liquid injection and discharge process of the extraction well is as follows:
when the well body 101 is cleaned, the first three-way valve 1064 is connected to the liquid inlet 1061, the second three-way valve 1065 is connected to the liquid inlet 1062, and at this time, a passage is formed between the liquid inlet 1061 of the liquid injection pipeline 106 and the liquid injection port 1062 of the liquid injection pipeline 106, and the cleaning liquid flows in from the liquid inlet 1061, flows through the liquid injection pipeline 106, and flows out from the liquid injection port 1062 into the well body 101, specifically, the cleaning liquid flowing out from the liquid injection port 1062 is sprayed on the inner pipe wall of the well body 101 by the spray head 10.
After the well 101 is cleaned, the first three-way valve 1064 is connected to the drain port 1063, and the second three-way valve 1065 is connected to the liquid outlet of the pump 107, so that a passage is formed between the liquid outlet of the pump 107 and the drain port 1063 of the liquid injection line 106, the pump 107 is started, and the pump 107 discharges the cleaning liquid, leachate, and other liquids accumulated in the well 101 from the drain port 1063 of the liquid injection line 106 to the outside of the well 101.
EXAMPLE III
The third embodiment is different from the first embodiment or the second embodiment in that the nozzle is an annular nozzle, and other structures are the same as those of the first embodiment or the second embodiment, so that detailed description is omitted.
Fig. 3 shows a cross-sectional view of the head in this embodiment. The nozzle 30 comprises an annular body 301, the annular body 301 is coaxially arranged outside the liquid injection pipeline 106, an annular liquid guide cavity 302 is formed inside the annular body 301, a liquid inlet of the annular liquid guide cavity 302 is communicated with a liquid injection port 1062 of the liquid injection pipeline 106, a plurality of liquid injection ports 303 are arranged on the side wall of the annular liquid guide cavity 302 at equal intervals along the circumferential direction, preferably, the liquid injection ports 303 are obliquely and downwards arranged, so that cleaning liquid can be better guided to the inner pipe wall of the well body, and the cleaning effect on the air suction hole is improved.
