The utility model is described in detail below in conjunction with accompanying drawing:

A sampler for an aeration tank, as shown in Figure 1, includes a sampler main body 1 and a sampling rack 2, the sampler main body 1 includes a sampling cylinder 3 and a pumping rod 4, and the sampling rack 2 includes a No. 1 fixing ring 5, No. 2 fixed ring 6, support frame 7, No. 1 telescopic device 8, No. 2 telescopic device 9, described No. 1 fixed ring 5 is sleeved on the top of sampling cylinder 3, and No. 2 fixed ring 6 is sleeved on sampling cylinder 3 At the bottom, the support frame 7 is arranged between the No. 1 fixed ring 5 and the No. 2 fixed ring 6, the No. 1 telescopic device 8 is arranged on the top of the No. 1 fixed ring 5, and the No. 2 telescopic device 9 is arranged on the drawer The top of the rod 4, the top of the No. 2 telescopic device 9 is rotatably connected with the No. 1 telescopic device 8, the bottom of the pumping rod 4 is provided with a gasket 10, and the No. 2 water inlet 12 is arranged on the gasket 10. The sampling cylinder 3 The top is provided with a sealing plate 14, the No. 1 water inlet 11 is arranged on the sealing plate 14, and the water outlet 13 is arranged at the bottom of the sampling cylinder 3. The No. 2 water inlet 12 is matched with the No. 1 water inlet 11 and has the same shape and size.

The No. 1 telescopic device 8 and the No. 2 telescopic device 9 are both arranged as two telescopic rods, and the telescopic rods are connected by connecting rods, and the two telescopic rods and the connecting rods are U-shaped.

The No. 2 telescopic device 9 is sleeved inside the No. 1 telescopic device 8 .

The middle position of the connecting rod of the second expansion device 9 is provided with a rotating shaft 15, and the top of the rotating shaft 15 is connected to the connecting rod of the first expansion device 8, and the second expansion device 9 and the first expansion device 8 are connected through the rotating shaft 15.

Both sides of the No. 1 fixing ring 5 and the No. 2 fixing ring 6 are provided with threaded holes, and the support frame 7 passes through the threaded holes, and is fixedly connected with the No. 1 fixing ring 5 and the No. 2 fixing ring 6 by bolts.

The outer wall of the sealing gasket 10 is closely matched with the inner wall of the sampling cylinder 3 , when the sealing gasket 10 rotates, sewage will not enter and exit between the outer wall of the sealing gasket 10 and the inner wall of the sampling cylinder 3 .

The water outlet 13 is smaller than the No. 1 water inlet 11, and the water outlet 13 is small enough that when the sampling cylinder 3 is filled with water, as long as the No. 1 water inlet 11 and the No. 2 water inlet 12 do not correspond, the sewage will not flow from the outlet. Water port 13 flows out.

Working principle of the present utility model: introduce the working principle of this sampler from the process of collecting sewage below.

First of all, it needs to be explained that in order to know when the No. 1 water inlet 11 and the No. 2 water inlet 12 are corresponding when the No. 2 telescopic device 9 is rotated, we use the method of adding marking lines for marking. The specific disclosure is as follows:

The No. 1 telescopic device 8 and the No. 2 telescopic device 9 are provided with marking lines. When the two marking lines correspond, the No. 1 water inlet 11 and the No. 2 water inlet 12 also correspond to meet the requirements of water inlet sampling. When the two marking lines are staggered, the No. 1 water inlet 11 and the No. 2 water inlet 12 are not corresponding, which meets the requirement of sealing the water sample after water intake.

As shown in Figure 1, Figure 2, and Figure 3, when sewage needs to be collected, the staff will bring the sampler to the side of the aeration tank, first turn the No. The sampling cylinder 3 rotates inside, so that the No. 1 water inlet 11 corresponds to the No. 2 water inlet 12, and then adjusts the length of the No. 1 telescopic device 8. At this time, the length of the No. 2 telescopic device 9 also changes with the No. 1 telescopic device 8. The bottom of the sampling cylinder 3 is slowly immersed in the sewage, and the sewage enters the sampling cylinder 3 from the No. 1 water inlet 11 and the No. 2 water inlet 12. When the sampling cylinder 3 is filled with sewage, turn the No. 2 telescopic device 9 again to make a The No. 1 water inlet 11 and the No. 2 water inlet 12 are no longer corresponding. At this time, the sealing plate 14 and the sealing gasket 10 are in a closed state. Since the diameter of the water outlet 13 at the bottom of the sampling cylinder 3 is relatively small, after the sampler is taken out from the aeration tank, The pressure outside the sampling cylinder 3 is higher than the pressure inside the sampling cylinder 3, and the water outlet 13 will not leak water. Finally, shorten the No. 1 telescopic device 8 and retract the sampler. When the sewage needs to be tested, just turn the No. 2 telescopic device 9. Make the No. 1 water inlet 11 correspond to the No. 2 water inlet 12. At this time, the internal pressure of the sampling cylinder 3 is greater than the external pressure of the sampling cylinder 3, and the sewage will flow into the detection instrument from the water outlet 13, and the staff can carry out follow-up Water quality testing and other work.

It should also be noted that, in order to save time and effort, the No. 1 telescopic device 8 and the No. 2 telescopic device 9 can also be set as electric telescopic rods. The gasket 10 can be made of rubber and other materials.

This sampler can also collect the sewage in the depth of the aeration tank. The specific operation is to first rotate the No. 2 telescopic device 9 so that the No. 1 water inlet 11 and the No. 2 water inlet 12 do not correspond. At this time, the sealing plate 14 and the sealing gasket 10 In a closed state, when the sampling cylinder 3 is slowly immersed in sewage, because the diameter of the water outlet 13 is relatively small, when the sampling cylinder 3 just enters the sewage, the pressure in the water is small, and the sewage will not enter the sampling cylinder 3. When it slowly enters the depth of the sewage , turn the No. 2 telescopic device 9 again, so that the No. 1 water inlet 11 corresponds to the No. 2 water inlet 12, and the sewage enters the sampling cylinder 3. When it is not necessary to continue collecting sewage, turn the No. 2 telescopic device 9 to make the No. 1 water inlet The water inlet 11 does not correspond to the No. 2 water inlet 12, and the sealing plate 14 and the sealing gasket 10 are in a closed state, so that the collected sewage can better detect the activated sludge in the depth of the aeration tank.

If the sampling cylinder 3 is broken, or when the sampling cylinder 3 needs to be cleaned, the staff can disassemble the bolt, separate the sampling cylinder 3 from the No. 1 fixing ring 5 and the No. 2 fixing ring 6, and replace or clean the sampling cylinder 3, This not only avoids the waste of resources, but also keeps the sampling tools clean and convenient for subsequent sampling work.

The above embodiments are only used to illustrate the technical solution of the utility model without limitation, other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the utility model, as long as they do not depart from the spirit and scope of the technical solution of the utility model, All should be included in the scope of claims of the present utility model.
