Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, specifically to a water sedimentation sampling device. Background Technology

[0002] Water quality monitoring is an important part of environmental protection. In the process of water quality monitoring, water samples need to be transported to a testing device, and then the testing device will detect various indicators in the water sample, and the data will be uploaded to achieve the effect of water quality monitoring.

[0003] Currently, water quality monitoring requires a sampling device to filter sand from the water sample to prevent it from entering the testing equipment. However, after a period of time, the sampling device needs to be manually disassembled to remove the filtered sand, making cleaning and maintenance inconvenient. Therefore, there is an urgent need to design a water sedimentation sampling device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a water sedimentation sampling device to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A water sedimentation sampling device includes an inlet pipe, a detection device at the top of the inlet pipe, a sampling pipe connected to one outer wall of the detection device, a filter assembly connected between the sampling pipe and the inlet pipe, the filter assembly including a filter housing, a fixing pipe welded to one outer wall of the filter housing, a filter cylinder fixed inside the fixing pipe, the top of the filter cylinder being fixed to the inner wall of the filter housing, and a solenoid valve connected to one end of the fixing pipe.

[0007] Furthermore, one end of the filter housing is connected to the water inlet pipe, and the other end of the filter housing is connected to a three-way connector. The end of the three-way connector away from the filter housing is connected to a solenoid valve three, and a connecting pipe is connected between the solenoid valve three and the sample supply pipe.

[0008] Furthermore, a solenoid valve four is connected to the top of the three-way connector, and a quick connector is connected to the top of the solenoid valve four.

[0009] Furthermore, a manual valve is connected to the middle of the connecting pipe.

[0010] Furthermore, an overflow pipe is connected to one side of the outer wall of the detection device, and a drain pipe is connected to the bottom end of the overflow pipe.

[0011] Furthermore, a second solenoid valve is connected between the detection device and the sewage pipe, and a fifth solenoid valve is connected between the water inlet pipe and the filter assembly.

[0012] In the above technical solution, the water sedimentation sampling device provided by this utility model has the following advantages: the sand in the water sample is filtered through the filter cylinder, and the sand settles into the interior of the downward-facing fixed tube. When it is necessary to clean the sand inside the filter assembly, the solenoid valve one is opened, and the sedimented sand is flushed out by the water flow, which makes the filter assembly of the sampling device easier to maintain. The solenoid valves three and five are closed, and the solenoid valves one and four are opened. Then, compressed air is introduced into the filter cylinder, which blows the sand that is blocked in the filter cylinder in the opposite direction and blows it out from the interior of the solenoid valve one, making the maintenance of the filter cylinder when it is blocked easier.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-3As shown in the figure, the water sedimentation sampling device provided in this embodiment of the utility model includes an inlet pipe 1, a detection device 3 is provided at the top of the inlet pipe 1, a sampling pipe 5 is connected to one side of the outer wall of the detection device 3, a filter assembly 2 is connected between the sampling pipe 5 and the inlet pipe 1, the filter assembly 2 includes a filter shell 8, a fixing pipe 9 is welded to one side of the outer wall of the filter shell 8, a filter cylinder 10 is fixed inside the fixing pipe 9, the top of the filter cylinder 10 is fixed to the inner wall of the filter shell 8, and a solenoid valve 11 is connected to one end of the fixing pipe 9.

[0021] Specifically, in this embodiment, an inlet pipe 1 is included. A water sample is input into the inlet pipe 1 by a water pump. A detection device 3 is installed at the top of the inlet pipe 1. The detection device 3 is existing technology and can detect key data reflecting water quality, such as pH, turbidity, and dissolved oxygen. A sample supply pipe 5 is connected to one side of the outer wall of the detection device 3. A filter assembly 2 is connected between the sample supply pipe 5 and the inlet pipe 1. The filter assembly 2 includes a filter shell 8. A fixing pipe 9 is welded to one side of the outer wall of the filter shell 8. The fixing pipe 9 is installed facing downwards. A filter cylinder 10 is fixed inside the fixing pipe 9. The top of the filter cylinder 10 is fixed to the inner wall of the filter shell 8, so that when water flows into the filter cylinder 10, the filter cylinder 10 can filter the sand in the water and deposit it in the fixing pipe 9 to prevent the sand from affecting the filtration effect of the filter cylinder 10. A solenoid valve 11 is connected to one end of the fixing pipe 9. When the solenoid valve 11 is opened, the deposited sand can be discharged.

[0022] The present invention provides a water sedimentation sampling device, which filters sand in water samples through a filter cylinder 10 and causes the sand to sink into the fixed tube 9 facing downward. When it is necessary to clean the sand inside the filter assembly 2, the solenoid valve 11 is opened, and the sedimented sand is flushed out by the water flow, thus making the filter assembly 2 of the sampling device more convenient to maintain.

[0023] In another embodiment of this utility model, one end of the filter housing 8 is connected to the inlet pipe 1, and the other end of the filter housing 8 is connected to a three-way connector 14. A solenoid valve 15 is connected to the end of the three-way connector 14 away from the filter housing 8. A connecting pipe 6 connects the solenoid valve 15 and the sample supply pipe 5, allowing the filtered water sample to enter the detection device 3 for testing. A solenoid valve 16 is connected to the top of the three-way connector 14, and a quick connector 17 is connected to the top of the solenoid valve 16. The quick connector 17 is connected to a compressed air source. A manual valve 7 is connected to the middle of the connecting pipe 6, which can be used for manual sampling. An overflow pipe 4 is connected to one side of the outer wall of the detection device 3, and a drain pipe is connected to the bottom end of the overflow pipe 4. The sewage pipe 13 allows excess water to flow out through the overflow pipe 4. When it is necessary to drain the water inside the detection device 3, the solenoid valve 2 12 is opened to drain the water inside the detection device 3. The solenoid valve 2 12 is connected between the detection device 3 and the sewage pipe 13, and the solenoid valve 5 18 is connected between the water inlet pipe 1 and the filter assembly 2. When the filter cartridge 10 is blocked, the solenoid valve 3 15 and the solenoid valve 5 18 are closed, and the solenoid valve 11 and the solenoid valve 4 16 are opened, so that compressed air enters the filter cartridge 10 from the three-way connector 14, causing the sand blocking the filter cartridge 10 to be blown away in the reverse direction and blown out from the inside of the solenoid valve 11.

[0024] Working principle: In use, open solenoid valve 18 to allow water to be sampled to enter the inlet pipe 1. The water sample then passes through the filter cartridge 10 of the filter assembly 2 for filtration, causing sand in the water sample to settle inside the filter cartridge 10. The water sample flows out of the filter assembly 2 and into the connecting pipe 6, then into the sample supply pipe 5, and finally into the detection device 3 for testing. Excess water flows out through the overflow pipe 4. When it is necessary to drain the water from the detection device 3, open solenoid valve 12 to achieve the effect of draining the water from the detection device 3. When the sand inside component 2 is discharged, close solenoid valve 3 15 and open solenoid valve 1 to achieve the effect of discharging the sand inside filter cartridge 10, making the filter device easier to clean. When filter cartridge 10 is clogged, connect quick connector 17 to the compressed air source, close solenoid valve 3 15 and solenoid valve 5 18, and open solenoid valve 1 11 and solenoid valve 4 16 to allow compressed air to enter the filter cartridge 10 from the three-way connector 14, causing the sand clogged inside the filter cartridge 10 to be blown away in the reverse direction and blown out from inside solenoid valve 11.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
