[0010] a second flow channel, the number of the second flow channels being several, the second flow channels being arranged at the other side of the main flow channel, and forming a closed loop with the main flow channel; after the liquid enters the main flow channel from the first inlet and is divided into the first flow channel and the second flow channel, the liquid flowing into the main flow channel has a flow direction opposite to that of the liquid in the main flow channel; after the liquid enters the main flow channel from the first outlet and is divided into the first flow channel and the second flow channel, the liquid flowing into the main flow channel has a flow direction identical to that of the liquid in the main flow channel;

[0011] The covering membrane has two covering membranes, and the covering membranes are arranged on the upper surface of the filter layer.

[0023] The working principle and beneficial effects of the utility model are:

[0024] 1. In the utility model, in order to solve the problem that the mold core does not have forward filtration and reverse cleaning, a roll-type flow channel net that is easy to clean is designed to achieve efficient filtration and easy maintenance and cleaning, including a filter layer, on which a plurality of filter flow channels are arranged, the filter flow channel is composed of a main flow channel, a first flow channel, and a second flow channel, the main flow channel has a first inlet and a first outlet, the first inlet and the first outlet are arranged at both ends of the filter layer, and the filter flow channel runs through the filter layer; the first flow channel and the second flow channel are respectively located on both sides of the main flow channel, the first flow channel and the second flow channel form a closed loop with the main flow channel, and covering films are arranged on the upper and lower surfaces of the filter layer.

[0025] Specifically, when it is necessary to filter out grease in the liquid, after the liquid enters the main channel from the first inlet and is diverted into the first channel and the second channel, the liquid that flows into the main channel flows in the opposite direction to the liquid in the main channel, which will have a counteracting effect on the liquid in the main channel, thereby slowing down the flow rate of the liquid in the main channel; after the liquid passes through the first channel and the flow rate is slowed down, it will be diverted from the main channel into the second channel on the other side. Since the second channel has the same structure as the first channel, the flow rate of the liquid in the main channel will be slowed down again. After passing through several first channels and second channels, the flow rate of the liquid in the main channel will gradually slow down. Due to the slowdown in the flow rate of the liquid, the grease inside the liquid will adhere to the inner wall of the filter channel, thereby achieving the effect of filtering the grease in the liquid; when there is too much grease attached to the filter channel and it needs to be cleaned, it is only necessary to inject high-pressure liquid from the first outlet. After the liquid enters the main channel from the first outlet and is diverted into the second channel and the first channel, the liquid that flows into the main channel has the same flow direction as the liquid in the main channel, so that the entire filter channel can be flushed. At the same time, the covering film covering the upper surface of the filter layer enhances the durability and service life of the filter layer.

[0026] The advantage of the overall design is that it utilizes physical principles and a complex and orderly flow channel structure to effectively slow down the flow rate in the filter channel, causing impurities such as grease in the liquid to adhere to the side walls of the filter channel, thereby improving the filtration efficiency and effect.

[0037] Reference Figure 1~Figure 4, which is the first embodiment of the utility model, proposes a flow channel net for a roll-type membrane that is easy to clean, including a filter layer 1; a filter flow channel 2 is arranged on the filter layer 1, and the number of the filter flow channels 2 is several, and the filter flow channels 2 include: a main flow channel 201 has a first inlet 2011 and a first outlet 2012, and the first inlet 2011 and the first outlet 2012 are respectively located at two ends of the filter layer 1; there are several first flow channels 202, and the first flow channels 202 are arranged on one side of the main flow channel 201 to form a closed loop with the main flow channel 201; there are several second flow channels 203, and the second flow channels 20 3 is arranged at the other side of the main channel 201, forming a closed loop with the main channel 201. After the liquid enters the main channel 201 from the first inlet 2011 and is divided into the first channel 202 and the second channel 203, the liquid flowing into the main channel 201 has an opposite flow direction to the liquid in the main channel 201; after the liquid enters the main channel 201 from the first outlet 2012 and is divided into the first channel 202 and the second channel 203, the liquid flowing into the main channel 201 has the same flow direction as the liquid in the main channel 201; there are two covering films 3, and the covering films 3 are arranged on the upper surface of the filter layer 1.

[0038] In this embodiment, in order to solve the problem that the mold core does not have forward filtration and reverse cleaning, a roll-type flow channel network that is easy to clean is designed to achieve efficient filtration and easy maintenance and cleaning, including a filter layer 1, on which a plurality of filter channels 2 are arranged, and the filter channel 2 is composed of a main channel 201, a first channel 202, and a second channel 203. The main channel 201 has a first inlet 2011 and a first outlet 2012, and the first inlet 2011 and the first outlet 2012 are arranged at both ends of the filter layer 1, and the filter channel 2 runs through the filter layer 1; the first channel 202 and the second channel 203 are respectively located on both sides of the main channel 201, and the first channel 202 and the second channel 203 form a closed loop with the main channel 201, and a covering film 3 is arranged on the upper and lower surfaces of the filter layer 1.

[0039] Specifically, when it is necessary to filter out grease in the liquid, after the liquid enters the main flow channel 201 from the first inlet 2011 and is divided into the first flow channel 202 and the second flow channel 203, the liquid flowing into the main flow channel 201 is opposite to the flow direction of the liquid in the main flow channel 201, which will have an offset effect on the liquid in the main flow channel 201, thereby slowing down the flow rate of the liquid in the main flow channel 201; after the liquid passes through the first flow channel 202 and the flow rate is slowed down, it will be diverted from the main flow channel 201 into the second flow channel 203 on the other side. Since the second flow channel 203 has the same structure as the first flow channel 202, the flow rate of the liquid in the main flow channel 201 will be slowed down again. After passing through a number of first flow channels 202 and second flow channels 203, the flow rate of the liquid in the main flow channel 201 will gradually slow down. As the flow rate of the liquid slows down, the grease in the liquid will adhere to the inner wall of the filter flow channel 2, thereby achieving the effect of filtering the grease in the liquid; when there is too much grease attached to the filter flow channel 2 and it needs to be cleaned, it is only necessary to inject high-pressure liquid from the first outlet 2012. After the liquid enters the main flow channel 201 from the first outlet 2012 and is divided into the second flow channel 203 and the first flow channel 202, the liquid flowing into the main flow channel 201 has the same flow direction as the liquid in the main flow channel 201, so that the entire filter flow channel 2 can be flushed. At the same time, the covering film 3 covering the upper surface of the filter layer 1 enhances the durability and service life of the filter layer 1.

[0040] The advantage of the overall design is that it utilizes physical principles and a complex and orderly flow channel structure to effectively slow down the flow rate in the filter channel 2, causing impurities such as grease in the liquid to adhere to the side wall of the filter channel 2, thereby improving the filtration efficiency and effect.

[0041] Furthermore, the first flow channel 202 includes a deviation channel 2021, which is linear. One end of the deviation channel 2021 is connected to the main channel 201, and the angle formed by the deviation channel 2021 and the main channel 201 is an acute angle; the return channel 2022 is semicircular, and the other end of the deviation channel 2021 is connected to the main channel 201 through the return channel 2022.

[0042] In this embodiment, the first flow channel 202 includes a deviation channel 2021 and a return channel 2022, wherein the deviation channel 2021 is linear and the return channel 2022 is semicircular. Specifically, it is necessary to filter out the grease in the liquid. When the liquid enters from the first inlet 2011 of the flow channel network, the liquid will enter the filtering flow channel 2, and the liquid will enter the main flow channel 201 and the deviation channel 2021 in the first flow channel 202 respectively. The angle formed by the deviation channel 2021 and the main flow channel 201 is an acute angle. The liquid entering the deviation channel 2021 will enter the return channel 2022 and finally merge into the main flow channel 201. Since the liquid flowing out of the return channel 2022 is in the opposite direction to the liquid flowing out of the main flow channel 201, the liquid flowing into the main flow channel 201 from the return channel 2022 will have a counteracting effect on the liquid in the main flow channel 201, thereby achieving the effect of slowing down the flow rate of the liquid in the main flow channel 201.

[0043] Furthermore, the second flow channel 203 has the same structure as the first flow channel 202 .

[0044] In this embodiment, the second flow channel 203 has the same structure as the first flow channel 202 , thereby achieving the effect of slowing down the flow rate of the liquid in the main flow channel 201 .

[0045] Furthermore, the filtering channel 2 has protrusions 204 inside, and the protrusions 204 are in a certain number and evenly distributed in the filtering channel 2 for attaching impurities in the water.

[0046] In this embodiment, the filter channel 2 has a plurality of protrusions 204 inside to enhance the roughness of the inner wall of the filter channel 2 so that the oil in the liquid can be better attached to the inner wall of the filter channel 2 .

[0047] Furthermore, the flow channel net 4 for the rolled membrane is rolled into a cylindrical shape, including a filter cartridge 5, and the flow channel net 4 for the rolled membrane is arranged in the filter cartridge 5; the mounting cover 6 is arranged at one end of the filter cartridge 5, and the mounting cover 6 is threadedly connected to the filter cartridge 5; there are two connecting heads 7, and the connecting heads 7 are respectively arranged at one end of the filter cartridge 5 and the mounting cover 6.

[0048] In this embodiment, the flow channel net 4 for the rolled membrane is rolled into a cylindrical shape, and the rolled flow channel net 4 for the rolled membrane is placed in the filter cartridge 5. The installation cover 6 is installed at one end of the filter cartridge 5 through the thread 701, and a connector 7 is further provided on the other end of the filter cartridge 5 and the installation cover 6. The advantage is that the flow channel net 4 for the rolled membrane can be perfectly utilized, and the mold core can be quickly and conveniently installed on the pipeline that needs to be filtered.

[0049] Furthermore, the end of the connector 7 away from the filter cartridge 5 has a thread 701 .

[0050] In this embodiment, the addition of the thread 701 makes the connection between the mold core and the external connection end more convenient and quick, and is easy to install.

[0051] Furthermore, the thread 701 is a pipe thread.

[0052] In this embodiment, the pipe thread 701 is tightly sealed, thereby enhancing the overall practicality.
