Description

Technical Field

[0001] The utility model relates to the technical field of water quality online monitoring instruments, in particular to an online water quality monitoring instrument with a back suction prevention function. Background Art

[0002] The automatic station type water quality online monitor is a continuous monitoring system. It is an effective means to achieve real-time monitoring and data transmission of water quality. It is widely used in the monitoring of water samples such as source water, drinking water, and wastewater. In source water, the online water quality monitor can detect pollution problems in time to ensure the safety of drinking water; in the field of drinking water, the online water quality monitor can achieve real-time monitoring and data transmission of water quality to ensure the quality of drinking water for citizens; in the field of wastewater, the online water quality monitor can monitor and analyze wastewater online to ensure the sewage treatment effect and water quality compliance. According to the application scenarios of the online water quality monitoring instrument, the instrument cannot be maintained in real time, and only regular maintenance and maintenance can be carried out, especially in the wild or on the lake in remote areas. Maintenance and maintenance are often affected by extreme weather, which brings difficulties to regular maintenance. With the continuous advancement of science and technology and the continuous improvement of water quality monitoring needs, the online water quality monitor will develop in a more intelligent, automated and efficient direction.

[0003] Affected by on-site conditions, if the online monitoring instruments are not maintained regularly, the waste liquid storage device may be easily filled up. The waste liquid discharge system of the online analytical monitoring instruments currently on the market is a one-way discharge system. When the waste liquid storage device is fully loaded, the internal negative pressure may easily cause the waste liquid to flow back, thereby affecting the accuracy of the detection system and even directly damaging the internal structure of the instrument, making it impossible to achieve real-time monitoring.

[0004] Therefore, the industry urgently needs to provide an anti-backflow device for online water quality monitoring instruments. When the instrument cannot be regularly maintained due to objective factors, the problem of waste liquid backflow caused by the full load of the waste liquid storage device can be solved, and reverse interception of a small negative pressure can be achieved to prevent backflow and ensure the normal operation of the instrument. Therefore, this application proposes an online water quality monitoring instrument with an anti-backflow function. Summary of the invention

[0005] The utility model aims to solve the problem of waste liquid backflow in online analysis and monitoring instruments in the background technology and proposes an online water quality monitoring instrument with a backflow prevention function.

[0006] The technical solution of the utility model is as follows: an online water quality monitor with a backflow prevention function, comprising a monitor cabinet and an analysis and detection module installed in the monitor cabinet, a waste liquid collection pipe for collecting waste liquid is installed on the outer wall of the monitor cabinet, and an anti-backflow device is installed between the analysis and detection module and the waste liquid collection pipe to prevent waste liquid from backflowing into the analysis and detection module;

[0007] The anti-backflow device includes a confluence adapter fixedly installed on the inner wall of one side of the monitoring instrument cabinet, a thin tube is connected between the analysis and detection module and the confluence adapter, a cylindrical pipe is installed at the bottom of the confluence adapter, a plurality of waste liquid holes for inserting thin tubes are opened on the top of the confluence adapter, the waste liquid holes are connected with the cylindrical pipe, a bent pipe is fixedly installed on the bottom of the cylindrical pipe, a pagoda joint is fixed between the bent pipe and the waste liquid collection pipe, a plurality of air outlet holes connected with the cylindrical pipe are opened on the top of the confluence adapter, and the inner diameter of the air outlet hole is 1.2-1.5 times the inner diameter of the waste liquid hole.

[0008] Optionally, the curved surface of the cylindrical pipe is connected to an ultrafine tube that is in communication with the inside of the cylindrical pipe, one end of the ultrafine tube is connected to an overflow bottle, and the inner diameter of the ultrafine tube is one fifth of the inner diameter of the capillary tube.

[0009] Optionally, a mounting hole is provided at the bottom of the confluence adapter, the cylindrical pipe is fixedly connected to the inner wall of the mounting hole, and the mounting hole is communicated with the waste liquid hole and the air outlet.

[0010] Optionally, a pipe clamp for clamping the cylindrical pipe is fixed to an inner wall of one side of the monitoring instrument cabinet.

[0011] Optionally, one end of the waste liquid collection pipe is connected to a waste liquid storage bin.

[0012] Optionally, the anti-backflow device is provided in multiple groups, and the pagoda connectors on the multiple groups of the anti-backflow device are all connected to the waste liquid collection pipe.

[0013] Compared with the prior art, the utility model has the following beneficial technical effects:

[0014] By arranging an air outlet hole connected to the cylindrical pipe on the confluence adapter, the negative pressure in the waste liquid storage bin can be effectively discharged to ensure smooth outflow of the waste liquid. At the same time, when the waste liquid flows back, it can overflow from the large-aperture air outlet hole to prevent the waste liquid from entering the analysis and detection module and causing damage to the instrument.

[0015] Furthermore, by connecting an ultra-thin tube to the cylindrical pipe and communicating it with the overflow bottle, the internal pressure can be effectively relieved, while avoiding the reflux of waste liquid to corrode the interior of the monitor cabinet, thereby improving the safety of use.

Therefore, the following detailed description of the embodiments of the present disclosure provided in the drawings is not intended to limit the scope of the present disclosure claimed, but merely represents selected embodiments of the present disclosure.

[0026] like Figure 1-2 As shown, the utility model proposes an online water quality monitor with anti-backflow function, including a monitor cabinet 1 and an analysis and detection module 2 installed in the monitor cabinet 1. The analysis and detection module 2 belongs to the prior art and will not be described in detail here. The outer wall of the monitor cabinet 1 is installed with a waste liquid collection pipe 12 for collecting waste liquid. The waste liquid collection pipe 12 is used to collect the waste liquid generated by the analysis and detection module 2.

[0027] like Figure 2-4As shown, in this embodiment, an anti-backflow device is installed between the analysis and detection module 2 and the waste liquid collection pipe 12 to prevent the waste liquid from being sucked back into the analysis and detection module 2, thereby avoiding the waste liquid from entering the analysis and detection module 2 and causing damage to the instrument. The anti-backflow device includes a confluence adapter 4 fixedly installed on the inner wall of one side of the monitoring instrument cabinet 1, a thin tube 3 is connected between the analysis and detection module 2 and the confluence adapter 4, and the thin tube 3 transports the waste liquid of the analysis and detection module 2 to the confluence adapter 4, and a cylindrical pipe 6 is installed at the bottom of the confluence adapter 4. The cylindrical pipe 6 adopts a 4-point PVC pipe, and a mounting hole 11 is opened at the bottom of the confluence adapter 4. The cylindrical pipe 6 is fixedly connected to the inner wall of the mounting hole 11. The mounting hole 11 is used to install and connect the cylindrical pipe 6, and a sealant is applied to ensure the sealing of the connection. A pipe clamp 5 for clamping the cylindrical pipe 6 is fixed on the inner wall of one side of the monitoring instrument cabinet 1, so as to realize the installation of the cylindrical pipe 6, which is easy to operate.

[0028] Among them, Figure 2-6 As shown, a plurality of waste liquid holes 9 for inserting the capillary tubes 3 are provided on the top of the confluence adapter 4, and the waste liquid transported by the capillary tubes 3 enters the waste liquid holes 9, and the waste liquid holes 9 of the capillary tubes 3 are connected to the cylindrical pipe 6, and a bend pipe 7 is fixedly installed at the bottom of the cylindrical pipe 6, and a pagoda joint 8 is fixed between the bend pipe 7 and the waste liquid aggregation pipe 12, and the pagoda joint 8 is a 1 / 2 pagoda joint, and one end of the waste liquid aggregation pipe 12 is connected to a waste liquid storage bin 15, and the waste water generated by the analysis and detection module 2 enters the confluence adapter 4 through the capillary tubes 3 and enters the cylindrical pipe 6 through the waste liquid holes 9, and then enters the waste liquid storage bin 15 from the waste liquid aggregation pipe 12 along the bend pipe 7 and the pagoda joint 8, thereby collecting the waste water generated by the analysis and detection module 2.

[0029] It is worth mentioning that a plurality of air outlet holes 10 connected to the cylindrical pipe 6 are provided on the top of the confluence adapter 4, the mounting hole 11 is connected to the waste liquid hole 9 and the air outlet hole 10, the air outlet hole 10 is connected to the air, and the inner diameter of the air outlet hole 10 is 1.2-1.5 times the inner diameter of the waste liquid hole 9, so as to facilitate the effective discharge of the negative pressure in the waste liquid storage bin 15 and ensure the smooth outflow of the waste liquid.
