Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In the above description of the utility model, it should be noted that the orientation or position relationship indicated by the terms "one side", "the other side", etc. is based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, and is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0028] In addition, the term "same" does not mean that the mechanisms must be absolutely identical, but slight differences are allowed. The term "vertical" simply means that the positional relationship between the mechanisms is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0029] See also Figure 1 and Figure 2 The utility model provides a technical solution: an automatic microbial filtering device, comprising a tank body 1, a filter screen 2 is fixedly connected to the tank body 1, the outer edge of the filter screen 2 is in contact with the inner wall of the tank body 1, and the filter screen 2 separates the internal space of the tank body 1, and a filtering space 21 and a flushing space 22 are formed on both sides of the filter screen 2;

[0030] The filtering space 21 is connected to a first pipe 3 and a second pipe 4 in a Y shape on one side away from the filter screen 2; the flushing space 22 is connected to a third pipe 5 and a fourth pipe 6 in a Y shape on one side away from the filter screen 2, and a solenoid valve 7 is installed on each pipe.

[0031] When the microbial automatic filtering device of the utility model is used, firstly, the second pipe 4 and the third pipe 5 are controlled to be closed respectively by the plurality of the solenoid valves 7, and the first pipe 3 and the fourth pipe 6 are opened, and then the turbid liquid containing microorganisms is introduced into the filtering space 21 through the first pipe 3, and the turbid liquid entering the filtering space 21 is filtered by the filter screen 2, so that impurities with a volume larger than the filter holes of the filter screen 2 remain on the left side of the filter screen 2, and microorganisms with a volume smaller than the filter holes of the filter screen 2 pass through the filter screen 2 and are discharged from the tank body 1 from the fourth pipe 6, thereby filtering and removing impurities with a volume larger than that of the microorganisms, and achieving rough filtration of the turbid liquid. After rough filtration, the turbid liquid can be introduced into the filtering device of the utility model (using a filter screen with a larger mesh number) for secondary filtration to remove impurities with a volume smaller than that of the microorganisms. Its working principle and operation steps are similar to those of the first filtration step, and no further elaboration is made here;

[0032] Then, the first pipe 3 and the fourth pipe 6 are controlled to be closed, and the second pipe 4 and the third pipe 5 are controlled to be opened respectively through the multiple solenoid valves 7, and clean water is added into the flushing space 22 through the third pipe 5 to flush out the impurities on the left side of the filter 2 and attached to the filter 2 from the second pipe 4, so as to clean the filter 2, reduce the possibility of the filter 2 being blocked, ensure the filtering efficiency and effect, and realize the integration of filtering and cleaning by cooperating with multiple pipes in pairs to reduce the steps of cleaning the filter 2 at a later stage. Finally, the utility model can control the opening or closing of the corresponding solenoid valve 7 by setting the time and the volume of the filtered turbid liquid, so as to make the filtering microorganism intelligent, so as to complete the filtering work in a timely, quantitative and automatic manner, and avoid the trouble of manual operation.

[0033] See also Figure 1 In this embodiment, a fifth pipe 8 is provided on the second pipe 4, and the other end of the fifth pipe 8 is connected to a vacuum generating component 9, and the vacuum generating component 9 is a vacuum pump. A waterproof and breathable membrane is provided in the fifth pipe 8 to prevent water from entering the vacuum pump and causing damage to the vacuum pump.

[0034] In this solution, when flushing the filter 2, clean water is added to the flushing space 22 through the third pipe 5, and then the air in the tank body 1 is extracted through the vacuum generating component 9 and the fifth pipe 8. At this time, the pressure in the tank body 1 is reduced, thereby increasing the flow rate of clean water flowing out of the third pipe 5 in the tank body 1, which can better pump out the impurities on the left side of the filter 2 and attached to the filter 2, thereby ensuring the flushing effect of the filter 2. The same vacuum generating component 9 can also be set on the fourth pipe 6, which is beneficial to accelerate the separation of microorganisms and impurities.

[0035] See also Figure 1 In this embodiment, the filter screen 2 is installed obliquely in the tank body 1, the surface of the filter screen 2 faces the liquid outlet of the first pipe 3, and the liquid inlet of the second pipe 4 is located at the lowest point between the tank body 1 and the filter screen 2.

[0036] In the present solution, the contact area between the filter screen 2 and the turbid liquid is increased by obliquely installing the filter screen 2 in the tank body 1, so as to improve the filtering efficiency of the turbid liquid, and the filter screen 2 is obliquely arranged at the liquid inlet of the second pipe 4, so that the moving direction of the impurities can be guided when cleaning the impurities, so that the impurities can be moved more completely to the liquid inlet of the second pipe 4, and finally discharged from the tank body 1 through the second pipe 4.

[0037] See also Figure 1 In this embodiment, the inner wall of the tank body 1 below the filter screen 2 is inclined away from the filter screen 2 to form a slope 10, and the liquid inlet of the fourth pipe 6 is located at the lowest point of the slope 10.

[0038] In this solution, the inclined surface 10 allows the microorganisms filtered by the filter 2 to smoothly move along the inclined surface 10 to the liquid inlet of the fourth pipe 6 , and to be relatively completely transferred out of the tank body 1 through the fourth pipe 6 .

[0039] See also Figure 1 , Figure 3 and Figure 4 In this embodiment, the liquid outlet of the second pipe 4 is connected to a recovery cylinder 11, a mounting ring 12 is fixedly connected to the inner wall of the recovery cylinder 11, a filter cylinder 13 is mounted in the mounting ring 12, and a circulation component 14 for exporting the liquid filtered by the filter cylinder 13 is provided on the recovery cylinder 11.

[0040] An observation window 15 is provided on the outer circumferential surface of the recovery cylinder 11 .

[0041] The recovery cylinder 11 includes a cylinder body 111 , on which a connecting pipe 112 for connecting to the second pipeline 4 is provided. The height of the liquid outlet of the connecting pipe 112 is higher than that of the filter cylinder 13 , and the top end surface of the filter cylinder 13 is concave downward.

[0042] In this solution, a cylinder cover is hingedly installed on the top of the cylinder 111, and the clean water containing impurities discharged from the second pipe 4 enters the filter cylinder 13 through the connecting pipe 112. The top end surface of the filter cylinder 13 is concave downward, and the top outer wall of the filter cylinder 13 is in contact with the inner wall of the cylinder 111, so that the clean water containing impurities entering the connecting pipe 112 can flow into the filter cylinder 13 more completely;

[0043] The clean water containing impurities is filtered by the filter cartridge 13, and the filtered clean water overflows between the filter cartridge 13 and the cylinder body 111, while the impurities remain in the filter cartridge 13. The filter cartridge 13 can be taken out of the cylinder body 111 by opening the cylinder cover to clean the filter cartridge 13. The amount of impurities in the filter cartridge 13 can be observed through the observation window 15, so that the filter cartridge 13 can be cleaned in time.

[0044] The clean water between the filter cartridge 13 and the cylinder body 111 can be transferred to the third pipe 5 through the circulation component 14 to continue to be used for flushing the filter screen 2, thereby saving the use of water resources.

[0045] See also Figure 1 In this embodiment, the circulation component 14 includes a circulation pipe 141 connected to the interior of the cylinder 111, and the other end of the circulation pipe 141 is connected to a water pump 142. The model of the water pump 142 is IS80-65-160, and the output end of the water pump 142 is connected to the third pipeline 5 through a pipeline.

[0046] In this solution, the clean water between the filter cartridge 13 and the cylinder body 111 is extracted by the water pump 142 and transferred to the third pipe 5 for continued use in flushing the filter screen 2, thereby saving the use of water resources.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
