Detailed Description
The following will further describe a novel bag filter for microfiltration according to the present invention with reference to the accompanying drawings.
As shown in fig. 1-4, a novel bag filter for precise filtration is characterized by comprising an upper shell 14, a lower shell 15, a sealing groove 4, a sealing ring 5, a supporting frame 6, a primary filter screen 9, a dirt storage groove 11, a dirt discharge 16, a bracket 8, a secondary filter screen 12, a filter bag 7, a pressure gauge 1, a water inlet pipe 10, a water outlet 3 and an exhaust hole 2; a sealing groove 4 is formed in the connecting part of the upper shell 14 and the lower shell 15, and a sealing ring 5 is arranged in the sealing groove; the upper shell 14 and the lower shell 15 are fixedly connected through bolts; the support frame 6 is installed outside the lower shell 15 through welding; the sewage storage tank 11 is arranged on a bracket 8 through welding, the bracket 8 is arranged on a lower shell 15 through welding, and the bracket 8 is provided with a communication port 17; one end of the sewage outlet 16 is welded on the lower shell 15 and is connected with the sewage storage tank; the water inlet pipe 10 is arranged on the lower shell 15 through welding and is connected with the sewage storage tank 11; the primary filter screen 9 is connected to the bracket 8 through welding; the secondary filter screen 12 is arranged at a communication port 17 of the bracket 8 through a bolt; the filter bag 7 is mounted on the bracket 8 through bolts; the water outlet 3 is arranged on the upper shell 14 through welding; the pressure gauge 1 is arranged at the top of the upper shell 14; the top of the upper shell 14 is provided with an exhaust hole 2; the primary filter screen 9 is a stainless steel sleeve type net structure which is a bag-shaped structure with an upward opening and a large upper part and a small lower part; and the filter bag is provided with a PVDF coating 13.
In the working process of the utility model, water enters the dirt storage tank 11 through the water inlet 10 and is then filtered through the primary filter screen 9, the water after primary filtering overflows into the filter bag 7 from the connecting port 17, the secondary filter screen 12 arranged at the connecting port 17 is used for secondary filtering in the process, the water after secondary filtering is positioned in the filter bag 7, the water after secondary filtering is used for tertiary filtering through the filter bag 7, and finally the water after tertiary filtering is discharged from the water outlet 3; in long-term use, after primary filtration is carried out in the sewage storage tank 11, large-particle impurities remained in the sewage storage tank are excessive, and blockage can be caused due to excessive impurities, so that the filtration efficiency of water is reduced, and therefore, the sewage discharge port 16 needs to be opened to discharge the impurities in the sewage storage tank 11; when the filter is cleaned, the upper shell 14 and the lower shell 15 are detached, then the filter bag 7 and the secondary filter screen 12 are detached, if the filter bag is required to be replaced, the filter bag is replaced without replacing, only the filter bag needs to be cleaned and then installed, impurities in the primary filter screen 9 can be discharged through the communicating port 17, and the filter can be reused after all the filters are cleaned or replaced. The pressure gauge 1 arranged at the top of the upper shell indicates the pressure inside the filter under the working state, and if the pressure is too large, the exhaust hole 2 is automatically opened, so that the internal pressure stability of the filter is ensured.
The utility model discloses beneficial effect through the setting with last casing 14 and lower casing 15, realizes the dismantled and assembled of filter to can regularly wash filter inner wall and filter screen, discharge the impurity in the filter, increase live time, reduce cost guarantees the filter effect. The second-stage filter screen 12 and the filter bag 7 are fixed by bolts, so that the filter bag is detachable and convenient to clean and replace, and impurities in the first-stage filter screen 9 can be cleaned after the second-stage filter screen 12 is detached during cleaning; through the arrangement of the sewage storage tank 11 and the sewage discharge outlet 16, impurities blocked by the primary filter screen 9 are temporarily stored in the sewage storage tank 11; the impurities in the sewage storage tank 11 are periodically cleaned and discharged through the sewage discharge outlet 16, so that the influence on the filtering efficiency and the filtering effect caused by excessive impurities in the sewage storage tank 11 is avoided; when the filter bag 7 is installed, the filter bag 7 is installed upside down, the opening faces downwards, the physical sedimentation effect can be utilized, the deposition of some larger pollutants on the bracket 8 is facilitated, and the water outlet 3 is arranged above the upper shell 14, so that the filtering effect is also facilitated to be improved; by adding PVDF coating on the filter bag 7, the temperature of the liquid which can be filtered is between 40 ℃ below zero and 150 ℃, the application range of the filter bag can be greatly increased.
