[0043] In the embodiment, when the wastewater in the purification needs to be sampled, the container used at the time is placed directly below the opening of the sampling tube 2013, and the movable pressing plate 2012 is pushed to move along the inner wall of the base 1 and is shrunk by extruding the second spring 209. At this time, the limiting shaft 208 moves synchronously under the pushing of the movable pressing plate 2012, and the lifting pressing plate 2011 is extruded by the movable pressing plate 2012 to drive the limiting sliding plate 2010 to ascend along the inner wall of the connecting sleeve plate 201.

[0044] At the same time, the wastewater in the inner cavity of the first rotating cylinder 7 contacts the outer wall of the fixed cylinder 203 along the inner wall of the first rotating cylinder 7. At this time, the wastewater enters the inner cavity of the fixed cylinder 203 through the water passage hole 2015. Then, the fixed cylinder 203 drives the wastewater to move under the rotation of the first rotating cylinder 7. At this time, the wastewater passes through the first sampling hole 202 along the inner wall of the fixed cylinder 203 and enters the inner cavity of the connecting sleeve plate 201. Then, the wastewater enters the inner cavity of the sampling groove 2014 along the outer wall of the lifting pressing plate 2011. After that, the wastewater falls into the container under the guidance of the inner wall of the sampling groove 2014 and the sampling tube 2013 in sequence.

[0045] As a preferred embodiment of the present application, the lifting pressing plate 2011 is inclined on one side, the movable pressing plate 2012 is matched with the lifting pressing plate 2011 at the joint position, and the top end of the lifting pressing plate 2011 is formed with symmetrical inclined surfaces.

[0046] In the embodiment, the inclined outer wall can make the lifting pressing plate 2011 move under the extrusion of the movable pressing plate 2012. At the same time, the connecting block 207 moves along the outer wall of the lifting pressing plate 2011 under the driving of the fixed cylinder 203 and the elastic extrusion of the first spring 204 through the connecting push rod 2016. In this process, the sealing sleeve 205 is reciprocated by the connecting push rod 2016, so as to automatically close the water passage hole 2015.

[0047] The working principle of the present application is: need to be particularly pointed out: the base 1 one end and located below the water pipe 13 is provided with a storage box for collecting the purified water.

[0048] When using the device, the motor 302 is started to drive the transmission wheel 301 to rotate, at this time the transmission ring 304 is driven by the synchronous belt 303 under the transmission wheel 301, through the connecting rotating pipe 4 to drive the first rotating cylinder 7 to rotate, at the same time the first rotating cylinder 7 is driven by the limiting ring 10 along the outer wall of the support sleeve frame 6 to rotate, in this process the connecting rotating pipe 4 is rotated on the outer wall of the drain pipe 5 through the bearing, at this time the first rotating cylinder 7 drives the second rotating cylinder 9 to rotate synchronously through the recovery cylinder 14, at the same time the sealing sleeve 205 is driven by the connecting sleeve plate 201 under the first rotating cylinder 7, through the connecting push rod 2016 to drive the connecting block 207 to move.

[0049] After that, the waste water is discharged into the second rotating cylinder 9 through the connecting rotating pipe 4 and the drain pipe 5, at this time the waste water can be purified by the limestone in the second rotating cylinder 9, and the purified water passes through the filter screen into the inner cavity of the first rotating cylinder 7, then the water passes through the water pipe 13 along the inner wall of the connecting end cover 12 to the outside, until falling into the storage box to store, so as to automatically collect the purified water.

[0050] In this process, part of the waste water in the purification process flows into the inner cavity of the first rotating cylinder 7 through the second sampling hole 8, at this time the second sampling hole 8 avoids the discharge of limestone in the second rotating cylinder 9 through the filter screen inside, and the leakage of waste water can be avoided through the sealing sleeve 205, at the same time the waste water contacts with the outer wall of the recovery cylinder 14 along the inner wall of the first rotating cylinder 7, then the recovery cylinder 14 is driven by the first rotating cylinder 7, through the rotation to make the port of the recovery groove 15 contact with the waste water, at this time the waste water enters the inner cavity of the recovery groove 15, then the recovery cylinder 14 rotates to make the waste water in the inner cavity of the recovery groove 15 enter the inner cavity of the second rotating cylinder 9 along the inner wall of the recovery groove 15, so as to recycle and purify the excess waste water.

[0051] When the waste water in the purification needs to be sampled, the container used at the time is placed directly below the opening of the sampling tube 2013, and the movable pressing plate 2012 is pushed to move along the inner wall of the base 1 and is retracted by extruding the second spring 209, at this time the limiting shaft 208 moves synchronously under the pushing of the movable pressing plate 2012, and the lifting pressing plate 2011 is extruded by the movable pressing plate 2012, which drives the limiting sliding plate 2010 to rise along the inner wall of the connecting sleeve plate 201, in this process, the connecting block 207 in movement pushes the connecting push rod 2016 to move along the inner wall of the fixed cylinder 203 and extrudes the first spring 204 and the bellows 206 to retract, at the same time, the sealing sleeve 205 is separated from the inner wall of the first rotating cylinder 7 under the pushing of the connecting push rod 2016 and moves along the outer wall of the fixed cylinder 203, until the inner cavity of the water passage hole 2015 and the inner cavity of the first rotating cylinder 7 are mutually penetrated, when the connecting block 207 and the outer wall of the lifting pressing plate 2011 are separated from each other, at this time the first spring 204 can automatically reset the connecting block 207 by rebounding, so as to realize the automatic opening and closing of the water passage hole 2015.

[0052] At the same time, the waste water in the first rotating cylinder 7 cavity contacts the outer wall of the fixed cylinder 203 along the inner wall of the first rotating cylinder 7, at this time the waste water enters the inner cavity of the fixed cylinder 203 through the water passage hole 2015, then the fixed cylinder 203 is driven by the rotation of the first rotating cylinder 7 to move the waste water, at this time the waste water passes through the first sampling hole 202 along the inner wall of the fixed cylinder 203 into the inner cavity of the connecting sleeve plate 201, then the waste water enters the inner cavity of the sampling groove 2014 along the outer wall of the lifting pressing plate 2011, after that, the waste water moves into the container under the guidance of the inner wall of the sampling groove 2014 and the sampling tube 2013 in sequence, then the movable pressing plate 2012 is loosened to reset the movable pressing plate 2012 by rebounding the second spring 209, and the reverse operation is performed on the above operation, so as to realize the purpose of non-stop sampling of waste water.

[0053] When the limestone is replaced, at this time the connecting end cover 12 is separated from the outer wall of the first rotating cylinder 7 by rotating, then the second rotating cylinder 9 is detached from the inside of the first rotating cylinder 7 and pulled out from one end of the first rotating cylinder 7, so as to replace the limestone.

[0054] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change within the technical range disclosed by the present application according to the technical solution and the inventive concept of the present application, which should be covered within the protection scope of the present application.
