Description

Technical Field

[0001] The utility model relates to the technical field of wastewater sampling, in particular to a wastewater sampling device. Background Art

[0002] At present, in order to analyze and test the wastewater generated in the industrial production process to understand relevant information such as the types, contents and discharge amounts of its pollutants, generally various detections will be carried out on the locally discharged wastewater. Before the detection, it is necessary to specifically sample the wastewater to send the sampled wastewater sample to the detection center for detection. Common sampling methods include directly scooping and sampling, and also deep sampling through a sampler, etc. The sampling method depends on the actual situation.

[0003] However, since the types of pollutants contained in wastewater are different at different depths, in order to more comprehensively detect relevant information of the wastewater, people will also collect wastewater at different depths. It is found that when using a sampler for collection, when sampling deeper wastewater, the sampling head on the sampler and a part of the pipeline will also contain wastewater from the upper depth. This results in the wastewater from the upper layer mixing and overlapping with the deeper wastewater, thus making the detected results not authoritative.

In order to ensure the smooth extraction of wastewater, a water pump 13 is fixed on the outer wall of one side of the box body 2. , and one end of a water suction pipe 14 is fixed to the water inlet end of the water pump 13, and a bellows 2 15 is fixed to the other end thereof, and the bottom end of the bellows 2 15 is fixedly connected to one end of the connecting pipe 12 located outside the box body 6, so that the bellows 1 1, the connecting pipe 12, the water suction pipe 14 and the bellows 2 15 are connected to form a passage, and one end of the bellows 3 16 is fixed to the water outlet end of the water pump 13, and a drain pipe 17 is fixed to the other end thereof, which is used to discharge the extracted waste water and the waste water after washing.

[0023] In this embodiment, in order to install the extracted wastewater samples, a profile frame 18 is fixed on the top of the vehicle plate 1, and three troughs 19 are opened on the top thereof, and sampling cups 20 are arranged in the three troughs 19.

[0024] In this method, in order to smoothly guide out the waste liquid after washing, a waste liquid cup 25 is fixed on the top of the molded frame 18. In the initial state, the drain pipe 17 is located above the waste liquid cup 25, and a drainage pipe is fixed at the bottom of the waste liquid cup 25, and the bottom end of the drainage pipe passes through the vehicle plate 1.

[0025] In the present method, in order to bring the discharge tube 17 to the top of the designated sampling cup 20, a horizontal platform 21 is fixed on the outer wall of one side of the box body 2, a box body 22 is fixed at the bottom thereof, and a transverse screw 23 is rotatably installed in the box body 22, and a connecting plate 24 is threadedly installed on the transverse screw 23.

[0027] The working principle of the wastewater sampling device provided by the utility model is as follows:

[0028] In the initial state of the device, the washing box 26 may contain detergent;

[0029] Before sampling the wastewater, start the second motor in the forward direction, and its output shaft drives the transverse screw 23 to rotate. Through the threaded cooperation between the transverse screw 23 and the connecting plate 24, the drain pipe 17 can be moved horizontally until the drain pipe 17 is moved to the top of the designated sampling cup 20, and then the second motor is turned off;

[0030] Then, the device is moved to the side of the wastewater pool, and the motor 1 is started forward, and its output shaft drives the lifting screw 3 to rotate. At this time, the threaded relationship between the lifting screw 3 and the lifting plate 4 is used to make the lifting plate 4 bring the box 6 down. When the box 6 drops to the specified depth, the motor 1 is turned off first, and then the output shafts of the two electric push rods 9 are started to extend, and the bottom plate 7 will be separated from the bottom of the box 6. At the same time, the profile frame 10 brings the bellows 11 down, so that the bellows 11 is at the depth, and then the water pump 13 is started to start extracting wastewater. The extracted wastewater enters the sampling cup 20 along various pipes. After the sampling is completed, the water pump 13 can be turned off;

[0031] When it is necessary to sample wastewater at another different depth next time, the motor 1 is started in reverse to bring the wastewater out of the box 6, and then the motor 2 is started in reverse to bring the drain pipe 17 back to the original position, where the bottom of the drain pipe 17 corresponds to the waste liquid cup 25, and then the washing box 26 is taken out and placed under the box 6, and then the washing box 26 is lifted from the bottom to the top, and finally the box 6 is immersed in the detergent therein, and then the water pump 13 is started again. , the detergent is extracted. During the extraction process, the detergent can not only clean the components such as the box body 6 and the bottom plate 7, but also circulate in each pipe, thereby cleaning each pipe. After that, the water discharged from the drain pipe 17 is the waste liquid after washing. These waste liquids are discharged along the waste liquid cup 25 and the drainage pipe. At this time, each pipe becomes relatively clean again. Then, the output shafts of the two electric push rods 9 are retracted to make the sealing ring on the bottom plate 7 contact with the bottom of the box body 6 again.

[0032] Then, the same steps as before can be followed to lower the box 6 into the wastewater to a specified depth again to continue the extraction and sampling work.

[0033] Compared with the related art, the wastewater sampling device provided by the utility model has the following beneficial effects:

[0034] The utility model provides a wastewater sampling device, through the provision of a box body 6 and a bottom plate 7, a bellows 11 for extracting wastewater can be temporarily sealed and wrapped, and then the motor 1 is started to lower the entire box body 6 to a specified depth in the wastewater pool, and then the bellows 11 is opened by starting the electric push rod 9 to perform the extraction and sampling work, so that the collected sample is a wastewater sample of the corresponding depth, which improves the high accuracy of sampling and can also ensure the authority of the subsequent detection results. In addition, when the next sampling is performed immediately, the box body 6 can be immersed in detergent, and then the detergent can be used to clean the components previously soaked in wastewater or the various pipes flowing through by starting the water pump 13, thereby effectively guaranteeing the next sampling result.
