[0002] The live virus wastewater treatment tank is a device used to treat live virus wastewater discharged by biopharmaceutical companies, laboratories, scientific research institutes and other units during the production process. The equipment mainly uses physical thermal sterilization methods to use high temperature to denature bacterial cells or inactivate coagulase, thereby killing bacteria; at the same time, the chemical bonds in DNA and RNA of the virus absorb heat at high temperature, causing the bonds to break, thereby inactivating the virus. The treated wastewater is cooled to meet the discharge standards and then discharged into the wastewater treatment plant.

[0003] In order to better understand the situation of the wastewater inside the live poison wastewater treatment tank, it is necessary to sample the live poison wastewater in the live poison wastewater treatment tank, and then a sampling device will be used. However, the current sampling of live poison wastewater treatment tanks is an open sampling method. The sampling process and after sampling may cause the dispersion of poisons due to incomplete inactivation. In order to avoid the dispersion of poisons due to incomplete inactivation, we provide a live poison wastewater treatment tank sampling device. Utility Model Content

[0021] Embodiment 1

[0022] See also Figure 1-4 The utility model provides the following technical solutions: a sampling device for a live poison wastewater treatment tank, comprising a sealing cover 1, a flange 2 is connected to the outer wall of the bottom end of the sealing cover 1, a bolt 3 is connected to the surface of the flange 2, a threaded rod 4 is threadedly connected to the surface of the sealing cover 1, a sampling barrel 5 is arranged at the bottom end of the sealing cover 1, a connecting column 6 is connected to the top end of the sampling barrel 5, a docking block 7 is installed on the surface of the connecting column 6, a fixing block 9 is connected to the top end of the docking block 7, and a limiting column 8 is connected to the bottom end of the fixing block 9.

[0023] Preferably, the flange 2 is connected to the outer wall of the bottom end of the sealing cover 1 by welding, and a placement groove larger than the diameter of the sampling barrel 5 is provided at the bottom end of the sealing cover 1 .

[0024] Preferably, the limiting column 8 extends downward to be connected to the top surface of the connecting column 6 , and the docking block 7 is fixed between the limiting column 8 and the connecting column 6 .

[0025] Preferably, the bottom end of the threaded rod 4 is connected with a rotating block 11 , and the bottom end of the threaded rod 4 forms a convex shape through the rotating block 11 , and the rotating block 11 is rotatably connected to the inside of the fixed block 9 .

[0026] Preferably, the fixing block 9 is connected to the sealing cover 1 in a lifting manner via the threaded rod 4 .

[0027] In the embodiment, the use of the sampling barrel 5 is described. First, manually hold the top of the threaded rod 4 and start to rotate. At this time, the threaded rod 4 begins to descend along the thread at the connection with the sealing cover 1. Then, the rotating block 11 at the bottom of the threaded rod 4 will rotate. At this time, the fixed block 9 will be divided into two states. 1. The fixed block 9 will rotate with the threaded rod 4, and 2. The fixed block 9 will not rotate with the threaded rod 4. Then the fixed block 9 will descend regardless of which state it is in. Then the descent of the fixed block 9 drives the limit column 8 to descend, and the limit column 8 is connected to the connecting column 6, and then the connecting column 6 will also descend. At the same time, the connecting column 6 is connected to the sampling barrel 5, and then the sampling barrel 5 will also descend. If it needs to rise, just rotate the threaded rod 4 in the opposite direction.

[0028] Embodiment 2

[0029] See also Figure 1-4 An ultraviolet lamp 10 is installed at the top of the cavity of the sealing cover 1, and two ultraviolet lamps 10 are provided, which are symmetrical about the center line of the sealing cover 1.

[0030] In the embodiment, the use of the ultraviolet lamp 10 is described. First, the ultraviolet lamp 10 is started to allow the light to be in the cavity of the sealing cover 1, and the ultraviolet lamp 10 can irradiate the outer wall and the interior of the sampling barrel 5. Then, the threaded rod 4 rotates to drive the sampling barrel 5 into the cavity of the sealing cover 1, and then the ultraviolet lamp 10 disinfects the sampling barrel 5 in the cavity of the sealing cover 1.

[0031] In summary, the specific working principle of the sampling device in the utility model is: Figure 5 First, the sampling device is close to the sampling port of the live toxic wastewater treatment tank, then, the flange 2 is connected to the sampling port of the live toxic wastewater treatment tank through the bolts 3, at this time, the sealing cover 1 is at the top of the sampling port, and the sampling bucket 5 is inside the live toxic wastewater treatment tank, then, manually hold the top of the threaded rod 4 and start to rotate, at this time, the threaded rod 4 begins to descend along the thread at the connection with the sealing cover 1, then, the rotating block 11 at the bottom of the threaded rod 4 will rotate, at this time the fixed block 9 will be divided into two states, 1, the fixed block 9 will rotate with the threaded rod 4, 2, the fixed block 9 will not rotate with the threaded rod 4, then the fixed block 9 will descend no matter what state it is in, and then the descent of the fixed block 9 drives the limit column 8 to descend, and the limit column 8 is connected to the connecting column 6, and then the connecting column 6 will also descend, and at the same time the connecting column 6 is connected to the sampling bucket 5, and then the sampling bucket 5 will also descend, and then the sampling bucket 5 will sink again After the sampling barrel 5 is filled with waste water, the sampling barrel 5 will be lifted up and the waste water in the sampling barrel 5 will be put into the sampling barrel 5. At the same time, the screw rod 4 is rotated in the opposite direction to make the sampling barrel 5 rise. At the same time, since the sampling barrel 5 is full of waste water, it will generate a certain weight, so that the rotating block 11 at the bottom of the screw rod 4 will rotate along the rotating groove opened in the fixed block 9 when cooperating with the fixed block 9. This avoids the fixed block 9 driving the sampling barrel 5 to rotate, and avoids the centrifugal force generated by the rotation of the sampling barrel 5 causing waste water to splash out. Then, the fixing bolts 3 are removed to remove the sealing cover 1 and the flange 2 from the sampling port of the live virus wastewater treatment tank, and the sampling barrel 5 is also taken out at the same time, so as to avoid the possibility of toxic dispersion during and after the sampling process due to incomplete inactivation. At the same time, the ultraviolet lamp 10 is used to perform ultraviolet disinfection on the outer surface of the sampling barrel 5 before sampling, and the inside of the sampling barrel 5 can be disinfected after sampling.

[0032] It should be noted that: Reference Figure 4It can be seen that the bottom end of the threaded rod 4 is connected to a rotating shaft, and the bottom end of the rotating shaft is connected to a bearing, and the rotating shaft and the inner ring of the bearing are fixedly connected, so that the rotating block 11 will not be affected by gravity and fit with the top end of the fixed block 9 for rotation, and the weight generated after the sampling bucket 5 takes wastewater causes the threaded rod 4 to rotate and drive the rotating shaft to rotate along the inner ring of the bearing, and at the same time, the sampling bucket 5 will not rotate due to the influence of the weight, which corresponds to the two states of the fixed block 9 in Example 1. When there is no wastewater in the sampling bucket 5, the lighter weight will drive the sampling bucket 5 to rotate, and when the sampling bucket 5 is full of wastewater, the heavier weight will not drive the sampling bucket 5 to rotate.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
