In addition, the terms "first", "second", etc. are only used for distinguishing descriptions, and should not be construed as indicating or implying relative importance.

In the description of the present disclosure, it should also be noted that, unless otherwise specified and limited, the terms "setting" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a direct connection, or an indirect connection through an intermediary, or it can be an internal connection between two elements. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present disclosure according to specific situations.

Y-type filter is a filter device commonly used in the pipeline system of conveying medium. Y-type filters are usually installed at the inlet of pumping devices or other equipment. Y-type filters can filter impurities in the conveying medium to protect the normal use of pumps, valves and equipment. In order to ensure the filtering effect, the Y-type filter needs to be cleaned every once in a while.

At present, the cleaning of the Y-type filter is mainly to shut down the pipeline system of the conveying medium, stop the conveyance of the medium, and then manually disassemble the cleaning part of the Y-type filter to clean up. However, it takes a long time to clean each shutdown, which often leads to the failure of normal conveying of the medium, which affects the production progress and affects the economic benefits of the enterprise.

In addition, there are still some disadvantages in manually cleaning the Y-type filter. For example, the installation space of the Y-type filter is relatively limited, and it is very inconvenient to operate when manually dismantling it. At the same time, there is a certain safety hazard of collision. In addition, the cleaning cycle of the Y-type filter can only be carried out based on manual experience, which may lead to impurity accumulation that cannot be cleaned in time, and may also be over-operated, resulting in high workload for workers. In addition, if the medium to be transported is acid, alkali, toxic and harmful chemicals, hot water, etc., not only need to stop the operation, but also need to take strict protective measures for workers, otherwise it is easy to cause safety hazards. The above drawbacks all increase the production cost and operation and maintenance cost of the enterprise, and all affect the economic benefits of the enterprise.

To this end, as shown in FIGS. 1-3 , an aspect of the present disclosure provides a Y-type filter cleaning system including a Y-type filter body 9 , a first on-off valve 3 , a second on-off valve 4 , a bypass pipe 6 and a third on-off valve 8 .

The Y-shaped filter body 9 has a liquid inlet 908, a liquid outlet 909 and a sewage outlet 910. The liquid inlet 908 is connected to the first end of the first switch valve 3, and the second end of the first switch valve 3 is used to be connected to the outlet of the first delivery pipeline 1. The liquid outlet 909 is connected to the first end of the second switch valve 4, and the second end of the second switch valve 4 is used to be connected to the inlet of the second delivery pipeline 10.

Wherein, the medium transported by the first delivery pipeline 1 can enter the Y-shaped filter body 9 through the first switch valve 3 and the liquid inlet 908, so that the medium is filtered in the Y-shaped filter body 9, and the filtered medium can enter the second delivery pipeline 10 through the liquid outlet 909 and the second switch valve 4, and be transported away by the second delivery pipeline 10.

Wherein, the first on-off valve 3 can connect or block the liquid inlet 908 and the first delivery pipe 1 , so that it is possible to choose whether to introduce the medium into the Y-shaped filter body 9 . The second on-off valve 4 can connect or block the liquid outlet 909 with the second delivery pipeline 10 , so that it is possible to choose whether to export the medium from the Y-shaped filter body 9 to the second delivery pipeline 10 .

Wherein, the bypass pipeline 6 is used to directly connect the first delivery pipeline 1 and the second delivery pipeline 10 , and the third switching valve 8 can conduct or block the bypass pipeline 6 .

It can be understood that when the Y-shaped filter body 9 needs to be cleaned, the first on-off valve 3 and the second on-off valve 4 can be closed so that the medium does not flow through the Y-shaped filter body 9 . At this time, the third on-off valve 8 is opened, so that the medium flows through the bypass pipeline 6, so that the first conveying pipeline 1 is connected to the second conveying pipeline 10 through the bypass pipeline 6, which can ensure medium conveyance, and at the same time, the Y-shaped filter body 9 can be cleaned, so that the medium conveyance is interrupted without stopping the machine, thereby ensuring the production progress.

In the above technical solution, the bypass pipeline 6 provided can guide the medium when the Y-shaped filter body 9 is cleaned, so that the first delivery pipeline 1 and the second delivery pipeline 10 remain connected, so that the medium can still be transported normally without shutting down, ensuring the normal production activities of the enterprise and the economic benefits of the enterprise. By setting the third on-off valve 8 on the bypass pipeline 6, the bypass pipeline 6 can be connected only when the Y-shaped filter body 9 needs to be cleaned, thereby ensuring the filtration and delivery of the medium under normal conditions. The provided first on-off valve 3 and second on-off valve 4 can interrupt medium delivery when the Y-shaped filter body 9 is being cleaned, which is convenient for cleaning the Y-shaped filter body 9 .

In this embodiment, by protruding the filter screen 7 from the first end of the bypass pipeline 6, a part of the filter screen 7 is extended into the first delivery pipeline 1, so that the impurities filtered by the filter screen 7 can be washed to the sewage outlet 910 of the Y-shaped filter body 9 when the Y-shaped filter body 9 is re-used in the follow-up.

It can be understood that when the Y-shaped filter body 9 is being cleaned, the medium in the first conveying pipeline 1 enters the bypass pipeline 6 through the filter 7 , and the impurities in the medium are intercepted by the filter 7 on the surface of the filter 7 . After the cleaning of the Y-type filter body 9 is completed, the Y-type filter body 9 is enabled, and the third on-off valve 8 cuts off the bypass pipeline 6. With the flow of the medium in the first conveying pipeline 1, the impurities intercepted on the surface of the filter screen 7 can be washed into the Y-type filter body 9, filtered and intercepted by the Y-type filter body 9 again, and can be cleaned with the next cleaning of the Y-type filter body 9, thereby prolonging the service life of the Y-type filter cleaning system.

As shown in FIG. 2 , optionally, in another embodiment of the present disclosure, the filter screen 7 is located at the end of the first end of the bypass pipe 6 .

Wherein, the filter screen 7 is flush with the end face of the first end of the bypass pipe 6 .

In some examples, the liquid inlet 908 and the liquid outlet 909 are located at both ends of the Y-shaped pipe body 901 , while the sewage outlet 910 is located in the middle of the Y-shaped pipe body 901 .

Wherein, the filter assembly 907 can filter the medium flowing in through the liquid inlet 908 to intercept impurities in the medium, and the filtered medium can be discharged from the liquid outlet 909 . The sewage assembly and the sewage outlet 910 can be separated. When the impurities intercepted in the Y-shaped filter body 9 need to be cleaned, the intercepted impurities can be discharged and cleaned through the sewage assembly. And when the filter assembly 907 needs to be replaced or maintained, the sewage discharge assembly can be removed from the sewage outlet 910 for replacement or maintenance, thereby ensuring the filtering effect.

Wherein, in order to ensure the filtering effect, the end of the filter assembly 907 away from the sewage assembly is located between the liquid inlet 908 and the liquid outlet 909, and the end of the filter assembly 907 away from the sewage assembly is in contact with the inner wall of the Y-shaped pipe body 901, so that the conveying medium enters from the liquid inlet 908 and is filtered by the filter assembly 907, and then discharged from the liquid outlet 909.
