[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4As shown, a sediment separation and water intake device for water quality monitoring includes a base 1, a column 2 on the outer side of the base 1, and a sedimentation tank 3 on the outer side of the column 2. The sedimentation tank 3 is fixedly installed on the base 1 by the column 2, and the sedimentation tank 3 is used to settle sediment in the water. The device also includes a cover plate 4 on top of the sedimentation tank 3, which is bolted to the top of the sedimentation tank 3 to seal it. A hydrocyclone 5 is installed on the outer side of the cover plate 4 to accelerate the settling of sand and gravel into the sedimentation tank 3, utilizing the hydrocyclone... Device 5 accelerates the settling of silt in the water flow. A drain pipe 9 is provided on the outside of the sedimentation tank 3 to discharge the water after sedimentation in the sedimentation tank 3. A filter assembly 10 is provided on the outside of the drain pipe 9 to filter the sand in the water flow again. A fixed shell 6 is installed at the bottom of the sedimentation tank 3. A sand discharge pipe 7 is provided on the outside of the fixed shell 6 to discharge the settled sand and gravel. A sand discharge assembly 8 is provided on the outside of the sand discharge pipe 7 to discharge the sand to the outside. The silt that falls into the sand discharge pipe 7 is discharged through the sand discharge assembly 8.
[0023] The fixed shell 6 is connected to the bottom of the sedimentation tank 3, and the sand discharge pipe 7 is connected to the bottom of the fixed shell 6. The settled silt falls into the fixed shell 6 and is then discharged into the sand discharge pipe 7 through the fixed shell 6.
[0024] The sand discharge assembly 8 includes an auger 801 disposed inside the sand discharge pipe 7. One end of the auger 801 is rotatably installed in the sand discharge pipe 7, and a connecting sleeve 802 is disposed on the outer side of the auger 801. The other end is rotatably installed on the connecting sleeve 802, which is bolted to the sand discharge pipe 7. A rocker arm 803 is disposed on the outer side of the connecting sleeve 802 and is fixedly connected to the auger 801. The rocker arm 803 drives the auger 801 to rotate, thereby conveying the silt at the bottom of the sand discharge pipe 7 upwards and discharging it through the opening at the upper end of the sand discharge pipe 7.
[0025] The filter assembly 10 includes a filter cover 1001 disposed outside the drain pipe 9. The filter cover 1001 is fixedly installed at the bottom of the drain pipe 9. A filter screen 1002 for filtering sand is disposed inside the filter cover 1001. The filter screen 1002 is installed in the filter cover 1001 via a mounting plate. The separated water in the sedimentation tank 3 is discharged through the drain pipe 9 and enters the filter cover 1001. It is then filtered again by the filter screen 1002 in the filter cover 1001 to remove fine sediment and improve the cleanliness of the water sample.
[0026] The sedimentation tank 3 is provided with a sand discharge port 11 at the bottom. The sediment in the sedimentation tank 3 is discharged into the fixed shell 6 through the sand discharge port 11. The inner wall of the sedimentation tank 3 is provided with a drain outlet 12. The settled water is discharged into the drain pipe 9 through the drain outlet 12. The bottom of the cover plate 4 is provided with a water distribution plate 13 to reduce the impact force of the water flow. The water distribution plate 13 is fixedly installed in the sedimentation tank 3. The water distribution plate 13 is used to disperse the water flowing down from the hydrocyclone 5, reduce the impact force of the water flow, and thus reduce the impact force of the water flow on the sediment at the bottom of the sedimentation tank 3, preventing the sediment at the bottom from being shaken up again. The outer side of the sand discharge pipe 7 is provided with a support rod 14 for supporting and fixing it. The support rod 14 is fixedly installed on the outer side of the sand discharge pipe 7 and fixedly installed on the base 1. The support rod 14 is used to support and fix the sand discharge pipe 7.
[0027] Working principle: Water sample is added through the inlet of hydrocyclone 5. The hydrocyclone 5 accelerates the sediment in the water to settle into the sedimentation tank 3. The separated water is discharged into the drain pipe 9 through the water pipe. The water mixed with sediment falls into the sedimentation tank 3 and settles. The sediment and other impurities settle to the bottom of the sedimentation tank 3 and fall into the sand discharge pipe 7 through the fixed shell 6. After sampling is completed, the auger 801 is shaken by the rocker arm 803. The auger 801 is used to transport the sediment at the bottom of the sand discharge pipe 7 upward and discharge the sediment through the opening at the top of the sand discharge pipe 7. The separated water in the sedimentation tank 3 is discharged through the drain pipe 9 and enters the filter cover 1001. It is filtered again by the filter screen 1002 in the filter cover 1001 to filter out the fine sediment in the water and improve the cleanliness of the water sample.
