Description

Technical Field

[0001] This utility model relates to the field of water filtration technology, specifically to a filtration and separation mechanism for water detection. Background Technology

[0002] During water body testing, pretreatment using a filtration and separation mechanism is required to remove interfering substances such as suspended particulate matter, colloids, algae, and microorganisms from the water sample, ensuring the accuracy and reliability of subsequent testing. Without effective filtration, impurities may clog the testing instrument's pipeline, adsorb the target detection substance, interfere with the detection signal, and cause data deviation.

[0003] Current water filtration and separation mechanisms generally follow a structure similar to that described in patent application CN202420558282.6, which discloses a pretreatment device for detecting suspended solids concentration in water. This device includes a water sample stratification unit comprising a filter cup, a connecting pipe connected to the filter cup, an extension connected to the connecting pipe, and a connecting branch pipe connected to the connecting pipe. The end of the connecting branch pipe furthest from the connecting pipe is located inside the filter cup. A leak switch is installed on the connecting pipe between the filter cup and the connecting branch pipe. A filter funnel, sealed to the extension, is used to filter substances from the water sample stratification unit. A suction flask, sealed to the filter funnel, is used to collect the filtrate filtered through the funnel. A suction pump is connected to the suction flask. However, the filter membrane of this invention is prone to clogging due to the accumulation of impurities in the water sample, requiring manual replacement. Manual operation can easily introduce cross-contamination, affecting data accuracy and making it difficult to meet the high-efficiency processing requirements of batch water samples.

[0004] Therefore, this utility model proposes a filtration and separation mechanism for water body detection to solve the above-mentioned problems. Summary of the Invention

A filter cylinder is fixedly connected inside the cylinder. A rotating shaft is rotatably connected to the first connecting frame and coaxially disposed inside the filter cylinder. Threaded blades are connected to the rotating shaft, which is coaxially connected to the drive shaft of a drive motor, which is fixedly connected to the first connecting frame. A top cover is connected to the end of the cylinder away from the water inlet assembly. The top cover is interference-fitted with the ends of both the cylinder and the filter cylinder. A telescopic connecting rod is connected to the end of the top cover. A first driving cylinder drives the telescopic connecting rod. The telescopic connecting rod and the first driving cylinder are both connected to a second connecting frame, which is connected to the body. A first water outlet pipe is connected to the bottom of the cylinder. A second water outlet pipe is threadedly connected to the bottom of the first water outlet pipe, and a filter element is disposed inside the second water outlet pipe.

[0007] Furthermore, the water inlet assembly includes a water inlet cylinder and a water inlet tank. A connecting plate is slidably connected inside the water inlet tank.

[0009] Furthermore, the filter cylinder is trapezoidal in shape, and the diameter of the filter cylinder increases sequentially along the water flow direction.

[0010] Furthermore, a scraper is connected to the rotating shaft. The scraper is L-shaped and abuts against the inner wall of the filter cylinder.

[0021] Furthermore, a filter cylinder 9 is fixedly connected inside the cylinder 3. The filter cylinder 9 is trapezoidal in shape, and its diameter increases sequentially along the water flow direction. A rotating shaft 10 is rotatably connected to the first connecting frame 2. The rotating shaft 10 is coaxially arranged inside the filter cylinder 9. A threaded blade 11 is connected to the rotating shaft 10, and a scraper 12 is also connected to the rotating shaft 10. The scraper 12 is L-shaped and abuts against the inner wall of the filter cylinder 9. The rotating shaft 10 is coaxially connected to the drive shaft of the drive motor 13, and the drive motor 13 is fixedly connected to the first connecting frame 2. A top cover 14 is connected to the end of the cylinder 3 away from the water inlet assembly. The top cover 14 is interference-fitted with the ends of both the cylinder 3 and the filter cylinder 9. A sealing strip 15 is connected to the top cover 14 corresponding to the periphery of the cylinder 3. The top cover 14 is connected to a telescopic link 16 at one end. The first drive cylinder 17 drives the telescopic link 16 to run. Both the telescopic link 16 and the first drive cylinder 17 are connected to the second connecting frame 18, which is connected to the body 1.

[0022] Furthermore, the cylinder 3 is detachably connected to the first connecting frame 2 via the end cap 19, the end cap 19 is threadedly connected to the first connecting frame 2, and the cylinder 3 is threadedly connected to the end cap 19; the drive shaft of the drive motor 13 is detachably connected to the rotating shaft 10, the end of the drive shaft of the drive motor 13 is connected to an external spline 20, and the rotating shaft 10 is correspondingly provided with an internal spline 21.

[0023] Furthermore, a first water outlet pipe 22 is connected to the bottom of the cylinder 3, and a second water outlet pipe 23 is threadedly connected to the bottom of the first water outlet pipe 22. A filter element 24 is installed inside the second water outlet pipe 23. A discharge hole 25 is opened at the end of the machine body 1 corresponding to the end of the cylinder 3. A baffle 26 is connected to the bottom periphery of the discharge hole 25, and a receiving box 27 is provided at the bottom of the machine body 1 corresponding to the discharge hole 25.

[0024] The working process of this utility model is as follows: First, the second drive cylinder 8 is activated. Then, the piston rod of the second drive cylinder 8 pushes the connecting plate 7 in the water inlet tank 6 to slide horizontally until the connecting plate 7 fully opens the channel between the water inlet tank 6 and the water inlet cylinder 5. Then, the water to be tested enters the water inlet cylinder 5 through the water inlet tank 6, and is then transported to the inside of the cylinder 3. After entering the cylinder 3, the water flows to the trapezoidal filter cylinder 9. The diameter of the filter cylinder 9 increases sequentially along the water flow direction, which can increase the filtration area. The water sample to be tested can flow along the filter cylinder 9, and the impurities in the water are intercepted by the filter cylinder 9. The filtered water permeates into the gap between the filter cylinder 9 and the cylinder 3.

[0025] Simultaneously, the drive motor 13 is started, and its drive shaft engages with the inner spline 21 of the rotating shaft 10 through the external spline 20, driving the rotating shaft 10 to rotate coaxially inside the filter cylinder 9. The threaded blades 11 on the rotating shaft 10 rotate with the shaft, which can stir the water, accelerate the water flow, improve the filtration efficiency, and also push some impurities to the end of the filter cylinder 9. At the same time, the L-shaped scraper 12 on the rotating shaft 10 continuously abuts against the inner wall of the filter cylinder 9, scraping off the impurities attached to the inner wall of the filter cylinder 9 during the rotation process, preventing impurities from clogging the filter holes and ensuring stable filtration effect.

[0026] The filtered water flows through the gap between the cylinder 3 and the filter cylinder 9 to the first outlet pipe 22 at the bottom of the cylinder 3, and then enters the threaded second outlet pipe 23 through the first outlet pipe 22. The filter element 24 inside the second outlet pipe 23 performs secondary filtration on the water to further remove tiny impurities and ensure that the water quality meets the testing requirements. Finally, the filtered water is collected from the outlet end of the second outlet pipe 23 for subsequent testing and analysis.

[0027] When a single filtration is completed or when a large amount of impurities accumulate on the inner wall of the filter cylinder 9, the filter residue cleaning process begins. The first drive cylinder 17 is activated, and its piston rod pulls the telescopic connecting rod 16 at the end of the top cover 14 to move axially. Under the pulling force of the telescopic connecting rod 16, the top cover 14 gradually separates from the cylinder 3 and the filter cylinder 9, opening the end opening of the cylinder 3. The drive motor 13 continues to run, and the rotating shaft 10 drives the threaded blades 11 and scraper 12 to continue working. The threaded blades 11 push the filter residue in the filter cylinder 9 toward the end opening, while the scraper 12 scrapes off the filter residue remaining on the inner wall and pushes it to the opening. The filter residue falls from the opening into the corresponding discharge hole 25 on the machine body 1. Guided by the baffle 26, it accurately falls into the receiving box 27 at the bottom, completing the centralized collection of the filter residue. After the filter residue is discharged, the first drive cylinder 17 is started in reverse. Its piston rod pushes the telescopic connecting rod 16 to reset the top cover 14, which then forms an interference fit with the end of the cylinder 3 and the filter cylinder 9. The sealing strip 15 then performs a sealing function again, allowing the next water filtration operation to proceed.

[0028] The cylinder 3 is threadedly connected to the first connecting frame 2 via the end cap 19, and the cylinder 3 and the end cap 19 are also threadedly connected, making it easy to remove the cylinder 3 from the first connecting frame 2 for inspection, cleaning, and replacement of the internal filter cartridge 9. It also allows rotation of the second water outlet pipe 23, which is threadedly connected to the first water outlet pipe 22, to replace the new filter element 24.
