Description

Technical Field

[0001] This utility model belongs to the technical field of water quality sampling devices, and in particular relates to a water quality sampling device that automatically filters impurities. Background Technology

[0002] In the field of water quality monitoring, water sampling devices are essential tools for obtaining and analyzing water samples. To ensure the accuracy of water samples, sampling devices typically need to be equipped with filtration functions to remove suspended solids, silt, and other impurities from the water. However, with traditional filtration devices (such as filter screens or filter cartridges), impurities easily adhere to the surface of the filter media or clog the pores after filtration, making cleaning difficult. Furthermore, accumulated impurities in the filtration device can reduce filtration efficiency or even cause it to fail completely. This not only affects the accuracy of the sampling results but also increases equipment maintenance costs. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a water quality sampling device that automatically filters impurities.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic water sampling device for filtering impurities includes a first filter box, a second filter box, and a water sample box;

[0006] The first filter box is equipped with a first water inlet pipe at the top, and the first filter box is filled with quartz sand;

[0007] The bottom of the first filter box is connected to the top of the second filter box, the bottom of the second filter box is connected to a water outlet pipe, and the other end of the water outlet pipe is connected to a water sample box.

[0008] The bottom of the second filter box is equipped with a filter screen;

[0009] The bottom of the first filter box is provided with a support component, which is used to open or close the connection between the first filter box and the second filter box;

[0010] The second filter box is equipped with a second water inlet pipe and a sewage outlet pipe at the upper and lower ends of its side, respectively.

[0011] An airbag is installed on the second water inlet pipe;

[0012] A cleaning brush is rotatably mounted on the filter screen, and the cleaning brush is detachably connected to the filter screen.

[0013] Valves are installed on the first water inlet pipe, the second water inlet pipe, the sewage pipe, and the water outlet pipe.

[0014] Through the above technical solution, water enters through the first inlet pipe and passes through the quartz sand in the first filter box, effectively removing suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odors, and some heavy metal ions. After a second filtration through the filter screen of the second filter box, the water enters the water sample tank. When cleaning is required, the support assembly and outlet pipe are closed, and a clean water source is connected through the second inlet pipe. The cleaning brush rotates to clean the surface of the filter screen, and the cleaned impurities are discharged through the drain pipe along with the wastewater. After cleaning the second filter box, the drain pipe is closed, the support assembly is opened, and water is introduced from the second filter box into the first filter box through the second inlet pipe, submerging the quartz sand. The valve of the second inlet pipe is closed, and the air bladder is squeezed to allow water to flow between the first and second filter boxes, vibrating and rubbing the quartz sand. Finally, the water source is connected through the second inlet pipe, allowing the wastewater in the first filter box to be discharged from the top of the first inlet pipe, completing the cleaning of both filter boxes and ensuring the subsequent water filtration effect.

[0015] Furthermore, the support assembly includes a first support plate and a second support plate, and the first support plate and the second support plate are respectively provided with through holes, the diameter of which is smaller than the diameter of the quartz sand particles;

[0016] The first support plate is fixedly installed on the inner wall of the first filter box, and the second support plate is rotatably connected to the first support plate and the inner wall of the first filter box.

[0017] By rotating the second support plate so that its through hole corresponds to the through hole of the first support plate, the first filter box and the second filter box can be connected. By rotating the second support plate so that its through hole is misaligned with the through hole of the first support plate, the bottom of the first filter box can be closed.

[0018] Furthermore, a first rotating groove is provided inside the first filter box;

[0019] The second support plate has a first rotating plate on its side, and the first rotating plate is rotatably disposed in the first rotating groove;

[0020] The first filter box has a toggle groove on its side, and a toggle block is slidably disposed in the toggle groove; the toggle block is fixedly connected to the first rotating plate.

[0021] With the above technical solution, the operator slides the toggle block to drive the first rotating plate and the second support plate to rotate, thereby opening and closing the bottom of the first filter box.

[0022] Furthermore, the filter screen is provided with a connecting shaft in the middle, and the upper end of the connecting shaft is located above the top of the filter screen and the top is square;

[0023] One end of the cleaning brush is provided with a connecting block, which is square and has a connecting groove on one side;

[0024] The connecting groove is inserted into the upper end of the connecting shaft.

[0025] Sliding grooves are provided on opposite sides of the connecting groove;

[0026] The connecting groove is provided with sliding blocks on opposite sides, and one end of the sliding block is slidably disposed in the sliding groove;

[0027] The sliding groove is provided with a first spring, and the two ends of the first spring are respectively connected to the sliding groove and the sliding block;

[0028] The second filter box has a mounting groove on its side, and a sealing plug is movably inserted into the mounting groove.

[0029] With the above technical solution, when the second filter box needs to be cleaned, the sealing plug is opened, the cleaning brush is inserted into the second filter box from the mounting groove and engaged with the connecting shaft. The filter screen is cleaned by rotating the connecting shaft. After cleaning, the cleaning brush is removed from the second filter box.

[0030] Furthermore, a pulling block is provided at the end of the cleaning brush away from the connecting block. The pulling block is slidably disposed inside the cleaning brush, and a hook is provided on the outer side of the pulling block.

[0031] The sliding block is connected to a pull rope on one side of the sliding groove. The cleaning brush has a pull rope groove inside, and the pull rope passes through the pull rope groove and is connected to one end of the pulling block.

[0032] The above technical solution uses a hook and ring to move a pulling block, which in turn causes a pulling rope to exert force on a sliding block, causing the sliding block to slide into the sliding groove. This completes the connection between the connecting block and the connecting shaft, allowing the cleaning brush to be removed from the second filter box.

[0033] Furthermore, a turntable is fixedly provided at the bottom of the connecting shaft, and a drive rope is wound inside the turntable;

[0034] The second filter box is equipped with a limiting rod, which is located below the filter screen;

[0035] One end of the drive rope passes through the limiting rod and extends out of the second filter box;

[0036] A torsion spring is fitted on the connecting shaft, with one end of the torsion spring connected to the connecting shaft and the other end connected to the turntable.

[0037] With the above technical solution, the connecting shaft can be rotated by pulling the drive rope to clean the surface of the filter box, and then reset under the action of the torsion spring.

[0038] Furthermore, the sealing plug is provided with a stop block, which blocks the cleaning brush, so that after the cleaning brush sweeps the filter screen along the surface once, it resets and rotates in the opposite direction under the action of the torsion spring.

[0039] This utility model has the following beneficial effects:

[0040] When cleaning is required, close the support assembly and the outlet pipe, connect a clean water source through the second inlet pipe, and rotate the cleaning brush to clean the surface of the filter screen. Finally, the cleaned impurities and sewage are discharged through the drain pipe. After cleaning the second filter box, close the drain pipe, open the support assembly, and input water from the second filter box into the first filter box through the second inlet pipe, submerging the quartz sand. Close the valve of the second inlet pipe, squeeze the air bladder to make the water flow between the first and second filter boxes, vibrating and rubbing the quartz sand. Finally, connect the water source through the second inlet pipe to discharge the sewage in the first filter box from the top of the first inlet pipe, completing the cleaning of the first and second filter boxes and ensuring the subsequent water filtration effect.
