Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a water sample pressure-free treatment device. Background Art

[0002] In the water treatment industry, when sampling sewage samples, it is usually necessary to lead a water pipe from the sewage drain pipe to collect sewage samples. However, since the sewage drain pipe has pressure inside, and the water sampler often needs to collect water samples without pressure, it is necessary to perform pressureless treatment on the sewage led out of the sewage drain pipe. The existing pressureless treatment often only uses a water pump and a water pipe to transport the sewage from the sewage drain pipe to a sampling cup, and then an opening is set at the upper end of one side of the sampling cup, and the opening is connected to a drain pipe, and the sewage in the sampling cup is discharged through the opening and the drain pipe, thereby obtaining pressureless sewage.

[0003] However, this pressureless treatment usually cannot be adjusted accordingly according to specific working conditions, resulting in that when the sewage flow is too large, the sewage inflow exceeds the operating load of the sampling cup and the drain pipe, resulting in the sewage water level in the sampling cup being too high or even overflowing, affecting the sampling effect. In addition, the overflowing sewage may contain various harmful substances, such as some harmful organic matter or heavy metal ions, which will cause environmental pollution to the construction site and may even cause serious harm to the health of on-site workers. In addition, after the sampling cup has been used for a period of time, it often needs to be emptied and cleaned to ensure that the sampling cup can operate normally. However, the existing design requires the sampling cup to be taken out of the device separately to empty the sewage in the sampling cup or clean the impurity deposits in the sampling cup, which is very inconvenient.

[0004] Therefore, the present application proposes a pressure-free water sample treatment device, which arranges a flow regulating device on the pipeline and monitors the sewage water level in the sampling cup in real time to prevent the sewage flow from exceeding the operating load of the sampling cup and the pipeline due to excessive sewage flow, and prevents the sewage in the sampling cup from overflowing and polluting the environment. Through the additional pipeline setting, the sampling cup can be emptied for sewage treatment without removing the sampling cup from the device. Utility Model Content

Water level, the liquid level detector 201 has a communication module or an electronic information transmission module; one end of the first pipeline 3 is connected to the first liquid port of the sampling cup 2, and the other end is connected to the sewage pipe. The first pipeline 3 is used to transport the sewage in the sewage pipe into the sampling cup 2; one end of the second pipeline 4 is connected to the overflow port of the sampling cup 2, and the other end of the second pipeline 4 is connected to the sewage pool.

[0031] In this embodiment, the inner diameter of the overflow port is at least twice the inner diameter of the first liquid port. By using an overflow port with an inner diameter larger than that of the first liquid port, the sampling cup 2 is prevented from being unable to discharge the sewage in the cup in time, causing the sewage to overflow from the top of the sampling cup 2, thereby causing pollution to the surrounding environment.

[0032] It is worth noting that the first pipeline 3, the second pipeline 4 and the third pipeline 5 are all stainless steel cylindrical water pipes. In other feasible embodiments, each of the pipelines may also be a glass fiber reinforced plastic cylindrical water pipe or other water pipes made of other known anti-corrosion materials or known structures, and the present application does not make too many limitations on the above.

[0033] In other alternative embodiments, the first liquid port may also be arranged at the middle and lower position of the side of the sampling cup 2, and a second liquid port may also be opened at the bottom of the sampling cup 2 for separate communication with the third pipeline 5. When the sampling cup 2 needs to be cleaned and emptied, the sewage in the sampling cup 2 is transported to the second pipeline 4 through the second liquid port and the third pipeline 5. The technical solution mentioned in the present application should be inspired by the relevant technologies of the above-mentioned settings, so the present application does not make too many limitations and redundant descriptions here.

[0034] Please refer to Figure 1As shown, in this embodiment, the first pipeline 3 is connected to the third pipeline 5 through the first three-way valve 9; the second pipeline 4 is connected to the third pipeline 5 through the second three-way valve 10. Through the above arrangement, the first pipeline 3 is connected to the inside of the third pipeline 5, and the third pipeline 5 is connected to the inside of the second pipeline 4, and a passage is generated, which is used to transport the sewage in the sampling cup 2 to the second pipeline through the first pipeline and the third pipeline in sequence, and then discharge it from the water sample pressureless treatment device proposed in this application.

[0035] It is worth noting that in other alternative embodiments, the first pipeline 3, the second pipeline 4 and the third pipeline 5 can also be connected by other known closed connection methods such as welding to ensure the formation of the passage, and the present application does not make too many limitations on the above.

[0036] In this embodiment, the water sample pressureless treatment device also includes a mounting back plate 1, and the mounting back plate 1 is used to install the various components mentioned in this application, including but not limited to the sampling cup 2, the first pipeline 3, the second pipeline 4 and the third pipeline 5; the mounting back plate 1 is usually arranged on a wall perpendicular to the horizontal plane, so that the water sample pressureless treatment device can be vertically set on the ground; the mounting back plate 1 is usually provided with a threaded opening for connecting to the wall by screws; it is worth noting that the mounting back plate 1 can also be set on the wall by other means such as bonding or welding. At the same time, the mounting back plate 1 can also be perpendicular to the horizontal ground by setting a bracket at the bottom. The mounting back plate 1 can be either a plastic mounting plate or an acrylic mounting plate, and this application does not make too many restrictions here.

[0037] In this embodiment, the first flow regulating component 6 includes a first valve, and the first flow regulating component 6 is used to adjust the opening of the first valve to control the size of the sewage flow in the first pipeline 3; a communication module or an electronic information transmission module is provided on the first flow regulating component 6; the communication module on the first flow regulating component 6 cooperates with the communication module on the liquid level detector 201; when the liquid level detector 201 detects that the sewage level in the sampling cup 2 is higher than a preset height, the communication module transmits an instruction to the first flow control device 6, and the first flow regulating component 6 reduces the opening of the first valve, thereby reducing the amount of sewage water transported to the sampling cup 2 through the first pipeline 3, and / or, when the liquid level detector 201 detects that impurities are generated in the sewage in the sampling cup 2 and precipitated in the sampling cup 2, the instruction is transmitted to the first flow control device 6, and the first flow control device 6 closes the passage in the first pipeline so that the sewage no longer enters the sampling cup 2.

[0038] It is worth noting that the preset height is determined according to the height of the sampling cup 2, usually two-thirds or three-quarters of the height of the sampling cup, and can be adjusted according to different working conditions. The present application does not make too many restrictions on this. In addition, the liquid level detector 201 can be an infrared liquid level detector, or a float-type liquid level detector or a water quality detector. When the liquid level detector 201 is an infrared liquid level detector or a water quality detector, it has the function of detecting the sediment content in the sewage. The above devices are all prior arts, and the present application does not make too many restrictions or elaborations here.

[0039] In this embodiment, a pressure detection component 11 is also provided on the first pipeline 3. The pressure detection component 11 is used to detect the sewage pressure in the first pipeline 3.

[0040] In this embodiment, a second flow regulating component 7 is provided on the third pipeline 5, and the second flow regulating component 7 is used to control the flow of sewage in the third pipeline 5; when the water sample pressureless treatment device is operating normally, the second flow regulating component 7 is in a normally closed state, so that the sewage cannot enter the second pipeline 4 through the third pipeline 5 and be discharged from the water sample pressureless treatment device; when sewage deposition occurs in the sampling cup 2, the first flow regulating component 6 is closed, so that the sewage no longer enters the sampling cup 2 from the first pipeline, and the second flow regulating component 7 is opened synchronously, so that the sewage in the sampling cup 2 flows into the second pipeline 4 through the third pipeline 5 and then is discharged; and the sampling cup 2 is rinsed, and the rinsing liquid after rinsing the sampling cup 2 also flows into the second pipeline 4 through the third pipeline 5 and then is discharged.

[0041] In the present application, each of the flow regulating devices can be an electric ball valve, a liquid level valve or a water pump, and all are made of corrosion-resistant materials. The corrosion-resistant materials include but are not limited to one of UPVC materials and copper materials. The present application does not make too many restrictions on the above.

[0042] Please refer to Figure 2 As shown, when the first flow regulating component described in the present application is an electric ball valve, Figure 2 This is a wiring diagram of the first flow regulating component 6 in this embodiment. When the water sample pressureless treatment device starts to operate and the sampling switch is allowed to be closed, and the liquid level detector 201 does not send a signal to the first flow regulating component 6 through the communication module or the electronic information transmission module, the liquid level switch is opened, so that the first flow regulating component 6 is in a passage state, and the sewage in the first pipeline 3 is normally transported to the sampling cup 2; when the liquid level detector 201 sends a signal to the first flow regulating component 6 through the communication module or the electronic information transmission module that the sewage level in the sampling cup 2 is higher than the preset value, the liquid level switch is closed, so that the first flow regulating component 6 is in an open circuit state, so that the sewage no longer enters the sampling cup 2 through the first pipeline 3.

[0043] It is worth noting that in the present application, the sampling cup 2 is made of transparent acrylic material, glass material or other transparent materials, and the light transmittance of the transparent material is usually higher than 90%, which is convenient for the operator to observe with the naked eye whether sediment is generated in the sampling cup 2, so as to determine whether the sampling cup 2 needs to be rinsed.

[0044] In summary, in the present utility model, a pressureless water sample processing device is proposed, which systematically solves the problem that when the sewage flow is too large, the sewage inflow exceeds the operating load of the sampling cup 2 and each of the pipelines, thereby causing the sewage water level in the sampling cup to be too high, or even overflowing, thereby affecting the sampling effect. Through the coordinated arrangement of the above components, the sampling cup 2 can be emptied and cleaned in a timely and convenient manner during the pressureless sewage sampling process, thereby increasing the service life of the sampling cup 2 and improving the accuracy of the pressureless water sampling. Through the arrangement of each flow regulating device, the sewage flow entering the sampling cup can be adjusted according to the working conditions to prevent the sewage flow entering the sampling cup from overflowing the sampling cup due to excessive flow, thereby causing environmental pollution, which is more environmentally friendly and safe.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
