Description
Technical Field
[0001] This utility model relates to the field of industrial wastewater treatment technology, specifically an industrial wastewater timed sampling device. Background Technology
[0002] With the acceleration of industrialization, the discharge of industrial wastewater is increasing day by day. It contains a large number of harmful substances, such as heavy metals and organic matter. If these substances are discharged directly into the environment without treatment, they will seriously threaten human health and ecological balance. In order to effectively monitor the pollutant content in industrial wastewater and ensure that the discharge meets the standards, environmental protection departments in various countries generally require industrial enterprises to establish a sound wastewater monitoring system. At present, the commonly used industrial wastewater sampling method is mainly manual sampling. Although manual sampling is simple to operate, it has problems such as low sampling frequency, high labor intensity, and susceptibility to human factors. It also cannot solve the problem of sample representativeness, that is, it cannot ensure that the collected samples can accurately reflect the water quality changes throughout the entire discharge cycle. Manual timed sampling is prone to deviation in time, either too short or too long, and it is easy to fail to collect samples accurately at the set time due to accidents. Utility Model Content

Timed sampling can collect samples at different time periods, avoiding the randomness and deviation that may be caused by sampling at a single time point, ensuring that the data can better reflect the water quality changes over the entire time period, avoiding the influence of human factors, and accurately reflecting the water quality changes over the entire discharge cycle. Secondly, the sample tube can be transported through the feeding component, and empty sample tubes can be transported to the sampling point. After sampling is completed, empty sample tubes are moved to the storage area and empty sample tubes are replenished for the next sampling.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0026] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0027] Example 1
[0028] like Figures 1-7 As shown, an industrial wastewater timed sampling device includes: a housing 1, an installation cylinder 11 fixedly installed at the bottom of the housing 1, two rotating disks 12 inside the installation cylinder 11, storage holes 13 respectively opened on the two rotating disks 12, sample tubes 14 inside the storage holes 13, and an inlet 15 opposite to one of the storage holes 13 at the top of the housing 1; a sampling component, which is located inside the housing 1 and is used to collect industrial wastewater at timed intervals; and a feeding component, which is located on the installation cylinder 11 and is used to control the sample tubes 14 to move to the sampling position.
[0029] Before use, the sample tube 14 is placed into the inlet 15. The top of the sample tube 14 is sealed with a rubber plug. The rubber plug can be repaired after being punctured to prevent leakage. The empty sample tube 14 is transported to the storage area by the feeding assembly and placed into multiple inlets 15 for sample storage. When treating industrial wastewater, the industrial wastewater is sampled at regular intervals by the sampling assembly so that changes in the industrial wastewater at different time periods can be detected. Regular sampling can capture these changes and ensure the representativeness of the monitoring results. During sampling, the sample tube 14 is moved to the sampling area by the feeding assembly, and wastewater sample is injected into the sample tube 14 for storage. After sampling is completed, the sample tube 14 is moved to the storage area.
[0030] Example 2
[0031] Based on Example 1, the sampling assembly includes: a water pump 2, a PLC control module 21, an electric telescopic rod a22, a moving plate 23, a solenoid reversing valve 24, and a puncture needle 25. The water pump 2 is fixedly installed on the inner wall of one side of the housing 1. The PLC control module 21 is fixedly installed on the inner wall of the housing 1 near the back. The electric telescopic rod a22 is fixedly installed at the bottom of the housing 1. The moving plate 23 is fixedly connected to the top of the electric telescopic rod a22. The solenoid reversing valve 24 is fixedly installed at the bottom of the moving plate 23. The device includes a puncture needle 25, a water supply pipe 26 fixedly connected to the output end of a water pump 2, one end of which is connected to the top of an electromagnetic reversing valve 24, and an input end of the water pump 2 extending to the outside and fixedly connected to a water pump pipe 27. The PLC control module 21 is electrically connected to the water pump 2. The puncture needle 25 has an outlet hole 28 and a drain hole 29 inside. A drain pipe 210 is fixedly connected to one side of the drain hole 29. One end of the drain pipe 210 passes through the housing 1 and extends to the outside. Gravity sensors 37 are fixedly installed at the top storage hole 13.
[0032] During sampling, the pumping pipe 27 is placed into the industrial wastewater. The sampling interval is set by the PLC control module 21. After the set time is reached, the PLC control module 21 starts the pumping pump 2 and the electric telescopic rod a22. After the electric telescopic rod a22 starts, it drives the moving plate 23 to move downward. The moving plate 23 pushes the solenoid reversing valve 24 and the puncture needle 25 downward, so that the puncture needle 25 punctures the rubber plug at the top of the sample tube 14. When the solenoid reversing valve 24 is not started, the water supply pipe 26 is connected to the outlet hole 28. After the pumping pump 2 starts, the industrial wastewater is drawn through the pumping pipe 27. The drawn industrial wastewater enters the puncture needle 25 through the water supply pipe 26. Since the water supply pipe 26 is connected to the outlet hole 28, the drawn sample... The sample flows into the sample tube 14. The gravity sensor 37 detects the weight of the sample tube 14 placed above in real time. When a certain amount of sample is collected, its weight reaches the weight value set by the PLC control module 21. Then, the electromagnetic reversing valve 24 is activated and the water pump 2 is turned off, so that the water supply pipe 26 is connected to the drain hole 29. Subsequently, the wastewater in the water supply pipe 26 is discharged from the drain hole 29 and discharged into the drain pipe 210. This controls the amount of sample. After the sampling is completed, the PLC control module 21 records the sampling time data and controls the electric telescopic rod a22 to push out, pushing the moving plate 23 to pull the puncture needle 25 out of the rubber plug of the sample tube 14. The rubber plug is repaired to prevent leakage, thus completing the sampling of the sample.
[0033] Among them, a fixed clamping plate 4 is fixedly connected to one side of the inner wall of the housing 1 near the position of the puncture needle 25, and a pneumatic rod 41 is fixedly installed at the bottom of the inner wall of the housing 1. A movable clamping plate 42 is fixedly connected to one end of the pneumatic rod 41 near the fixed clamping plate 4.
[0034] During sampling, the pneumatic rod 41 is activated to push the movable clamp 42 to move towards the fixed clamp 4, so that the movable clamp 42 contacts the sample tube 14. The sample tube 14 is clamped by the movable clamp 42 and the fixed clamp 4, thereby fixing the sample tube 14 and preventing the puncture needle 25 from pulling the sample tube 14 when it is inserted or removed.
[0035] Example 3
[0036] Based on Embodiment 1, the feeding assembly includes: a connecting cylinder 3, a connecting frame 31, a rotating rod 32, a driven gear 33, a splined shaft 34, a reducer 35, and a driving gear 36. The connecting cylinder 3 is fixedly connected between the two rotating disks 12 on opposite sides. Two connecting frames 31 are fixedly connected between the inner walls of the connecting cylinder 3. The rotating rod 32 is rotatably connected to the bottom of the housing 1. The driven gear 33 is fixedly connected to the top of the rotating rod 32. The splined shaft 34 is fixedly connected to the top of the driven gear 33. The top tube of the splined shaft 34 passes through the two connecting frames 31. The reducer 35 is fixedly installed at the bottom of the mounting cylinder 11. The drive shaft at the top of the reducer 35 extends into the interior of the mounting cylinder 11 and is fixedly connected to the driving gear 36. The driving gear 36 meshes with the driven gear 33. An electric push rod b38 is fixedly installed at the bottom of the housing 1 at a position opposite to the inlet 15. A push block 39 is fixedly connected to the top of the electric push rod b38. A through hole 310 is opened at the bottom of the mounting cylinder 11 to allow the electric push rod b38 to pass through.
[0037] During sampling, the PLC control module 21 starts the reducer 35. After starting, the reducer 35 drives the drive gear 36 to rotate. The drive gear 36 meshes with the driven gear 33, which in turn drives the rotating rod 32 and the spline shaft 34 to rotate. The spline shaft 34 drives the connecting frame 31 to rotate. The connecting frame 31 drives the two rotating disks 12 to rotate through the connecting cylinder 3. The rotating disks 12 move the sample tube 14 a distance of one storage hole 13. Then the reducer 35 shuts off and stops working. The top of the housing 1 has a viewing window to observe whether the sample tube 14 has moved to the sampling position. If it has not yet reached the sampling position, the above steps are repeated until the sample tube 14 is moved to the sampling position. At the same time, when the sample tube 14 moves, an empty sample is put into the inlet 15. The sample tube 14 is used to ensure that there is an empty sample tube 14 to replenish after sampling, so as to facilitate the next sampling operation. After sampling is completed, the reducer 35 is started again to move the sample tube 14 containing the sample, and the empty sample tube 14 is replenished. When taking samples, the sample to be taken in the required time period is selected by the PLC control module 21. The PLC control module 21 starts the reducer 35 to control the corresponding sample tube 14 to move to the inlet 15. Then the electric push rod b38 is started. After the electric push rod b38 is started, it pushes the push block 39 to move upward. The push block 39 lifts the sample tube 14, so that the sample tube 14 is pushed out of the inlet 15 for easy picking, or the sample tubes 14 are taken out in order from left to right.
