The ordinary filter paper filtering can only rely on gravity or a small amount of negative pressure. When the impurities in the sewage are more, the particles are finer, or contain colloidal components, the filter hole is easily blocked. For example, the sewage containing a large amount of silt and microorganisms, the fine silt particles and microorganisms gather together, which can quickly block the pores of the filter paper, causing the filtration speed to drop sharply.

By setting the first filter screen and the second filter screen, the first filter screen can filter relatively large particles in sludge, avoiding the blockage of the second filter screen by large particles. The second filter screen can filter small particles. Water is continuously fed through the liquid inlet pipe, which can filter the sewage in the filter box through the filter screen, improve the efficiency of sewage filtration, and drive the motor and the stirring rod.

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] Please refer to Figures 1-5 The utility model provides technical schemes:

[0028] A sewage rapid filtration structure for environmental detection, comprising a box 1, the left side of the box 1 is communicated with a connecting pipe 2, the outer side of the connecting pipe 2 is provided with a filtration assembly 4, the inside of the box 1 is provided with an auxiliary assembly 5;

[0029] The filtering assembly 4 comprises a filtering box 401 bolted to the outer side of the connecting pipe 2, a cyclone generator 402 bolted to the right side inside the filtering box 401, a magnetic ring body 403 bolted to the inner side of the filtering box 401, a fine filter screen 404 bolted to the left side inside the filtering box 401, a protective shell 405 bolted to the left side of the filtering box 401, a sealing ring 406 arranged on the outer side of the protective shell 405, a rotating groove 407 formed in the inner side of the protective shell 405, a coarse filter screen 408 movably connected to the inner side of the rotating groove 407, and a water inlet pipe 409 bolted to the left side of the protective shell 405.

[0030] In this embodiment, sewage is delivered into the filtering box 401 through the water inlet pipe 409, and the coarse filter screen 408 in the protective shell 405 first performs preliminary filtration on the sewage to intercept large-particle impurities, and meanwhile, the coarse filter screen 408 can rotate in the rotating groove 407 to adjust the position of the coarse filter screen 408 when subjected to a large water flow impact or impurity accumulation to avoid serious local blockage. Then, the sewage filtered by the coarse filter screen enters the filtering box 401, and the fine filter screen 404 can intercept small-particle impurities such as fine silt and part of suspended matters to ensure that the sewage entering the tank 1 has a greatly reduced impurity content. Meanwhile, the magnetic ring body 403 adsorbs ferromagnetic impurities in the sewage to further purify the sewage. Then, the cyclone generator 402 is started to change the direction and speed of the water flow through a specific flow channel or blade structure, so that the sewage forms a high-speed rotating water flow in the filtering box 401. In the rotating process, the water flow can process the impurities intercepted by the fine filter screen 404, so that the intercepted silt and other heavy particles are subjected to the action of centrifugal force and are flung toward the inner wall of the filtering box 401 to be collected at the bottom of the filtering box 401 to prevent the fine filter screen 404 from being blocked and improve the filtering efficiency.

[0034] In the embodiment, the sewage after the preliminary filtration is introduced into the box 1 through the connecting pipe 2, the sewage is subjected to the deep filtration by the multi-layer composite filter membrane 507 of the box 1 from outside to inside in turn, different sizes and properties of pollutants are intercepted, the outer layer intercepts the larger residual particles, then the middle layer removes colloids and part of dissolved organic matter, then the inner layer intercepts smaller impurities and ions, then the ultrasonic generator 504 of the box 1 is started, then the ultrasonic generator 504 generates a high-frequency electric signal, which is converted into mechanical vibration through the ultrasonic transducer 505, and is transmitted to the vibration plate 506, so that the vibration plate 506 generates ultrasonic waves in the sewage in the box 1, the ultrasonic waves form a cavitation effect, decompose complex pollutants such as organic macromolecules and microbial aggregates in the sewage, and make them become smaller particles or molecules, then the circulating pump 502 is started, then the circulating pump 502 draws the sewage in the box 1 through the circulating pipe 503 and sends it back to the box 1, so that the sewage passes through the vibration plate 506 and the multi-layer composite filter membrane 507 for multiple times, and the purification effect is enhanced.

[0035] Specifically, as shown in Figure 5 , the right side of the box 1 is communicated with the conveying pipe 6, and the outer side of the conveying pipe 6 is provided with the electromagnetic valve 7.

[0036] Specifically, as shown in Figure 5 , both sides of the box 1 are fixedly connected with the sealing plates 8, and the outer sides of the sealing plates 8 are sleeved with the sealing pads 9.

[0037] In the embodiment, by arranging the conveying pipe 6 and the electromagnetic valve 7, when it is needed to discharge the purified water during the filtration process, an opening signal is sent to the electromagnetic valve 7 through the control system, then the electromagnetic valve 7 is opened, under the water pressure in the box 1, then the purified water is smoothly discharged through the conveying pipe 6, when it is not needed to discharge water, the electromagnetic valve 7 is closed through the control system to prevent the water from flowing out, so that the filtration process is carried out in a closed environment, the pressure and water level in the box 1 are maintained stable, so as to ensure the filtration effect, by arranging the sealing plates 8 and the sealing pads 9, the sealing plates 8 and the sealing pads 9 effectively prevent the sewage from leaking from the connecting part of the box 1 during the filtration process, so as to ensure the integrity and stability of the whole filtration structure, and prevent the sample loss or pollution affecting the detection result caused by the leakage.

[0038] Specifically, as shown in Figure 1 , the bottom of the filter box 401 is bolted with the support 10, and the bottom of the support 10 is fixedly connected with the supporting legs 11.
