[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0035] In the related art, the filter usually has a built-in filter screen, which intercepts solid particles in the liquid during the filtering process. As the filtering time increases, the blockage on the filter screen increases, affecting the filtering flow, so the blockage on the filter screen needs to be cleaned regularly. The commonly used method is to disassemble the filter screen and remove it for manual cleaning, but disassembly and manual cleaning are complicated and time-consuming.

[0036] In order to solve the above problems, the utility model provides a beam flushing self-cleaning filter device and system to solve the problem that the filter cleaning operation is complicated and time-consuming.

[0037] The following combination Figures 1 to 3 , describing the embodiments of the present utility model.

[0038] According to an embodiment of the present invention, on the one hand, a beam flushing self-cleaning filter device is provided, which can be applied to the filtration of liquids, such as the filtration of coolant in a cooling system, and the filtration of liquids in various liquid circulation systems, such as Figure 1 and Figure 3As shown, it includes a filter channel 1, a filter assembly 2 and a beam channel 3. The filter channel 1 is provided with a liquid inlet 101, a liquid outlet 102 and a sewage outlet 103. The liquid outlet 102 is connected to a liquid outlet valve 104 for connecting to the liquid outlet pipe 6 to output the filtered liquid. Figure 3 As shown, a drain valve 105 is provided on the drain outlet 103; the filter assembly 2 is cylindrical with openings at both ends, and is arranged in the filter channel 1 to filter the liquid entering the liquid outlet 102, one end opening of the filter assembly 2 is connected to the liquid inlet 101, and the other end opening of the filter assembly 2 is connected to the drain outlet 103; one end opening of the beam channel 3 is connected to the liquid inlet 101, and the other end opening of the beam channel 3 is used to connect with the liquid inlet pipe 5 to input the liquid to be filtered, and a guide body 301 is provided in the beam channel 3, and the guide body 301 extends along the axial direction of the beam channel 3; wherein, the axis of the beam channel 3 and the axis of the liquid inlet 101 coincide with the axis of the filter assembly 2, and the inner cross-section of the beam channel 3 and the cross-section of the liquid inlet 101 are the same as the inner cross-section of the filter assembly 2.

[0039] It should be noted that, the above-mentioned "the axis of the beam channel 3 and the axis of the liquid inlet 101 coincide with the axis of the filter assembly 2, and the internal cross-section of the beam channel 3 and the cross-section of the liquid inlet 101 are the same as the internal cross-section of the filter assembly 2" not only means that the internal cross-section of the beam channel 3 and the cross-section of the liquid inlet 101 are the same as the shape of the internal cross-section of the filter assembly 2, but also means that the corresponding positions along the axial direction of the beam channel 3 are the same; this is to ensure the beam effect of the liquid. Specifically, if the internal cross-section of the beam channel 3, the cross-section of the liquid inlet 101 and the internal cross-section of the filter assembly 2 are all isosceles triangles, if the top angle of the internal cross-section of the beam channel 3 faces upward, then the top angle of the cross-section of the liquid inlet 101 and the top angle of the internal cross-section of the filter assembly 2 are also facing upward.

[0040] Specifically, the inner cross-section of the beam channel 3 can be a rectangle, square, circle, triangle, polygon with a pentagon or larger shape, etc.; the cross-section of the flow guide 301 can also be a rectangle, square, circle, triangle, polygon with a pentagon or larger shape, etc., which can be selected and adjusted according to actual needs; the mesh diameter of the filter component 2 is 5 to 10 mm.

[0041] During the work process, Figure 3As shown, the self-cleaning filter is taken as a part of the heat exchange system for example. The beam channel 3 in the self-cleaning filter is connected to the water outlet of the heat exchanger in the heat exchange system through a water pump, and the liquid outlet valve 104 is connected to the water inlet of the refrigeration hydrazine. The circulating water in the heat exchange system is pushed to circulate by the power of the water pump; under the filtering condition, the liquid outlet valve 104 is opened and the drain valve 105 is closed. The circulating water coming out of the heat exchanger passes through the water pump, the beam channel 3, the liquid inlet 101, the filter component 2 and the liquid outlet 102 in sequence, and then enters the refrigeration hydrazine. When the circulating water passes through the filter component 2, the large particles of debris in the circulating water are blocked by the filter component 2 and retained on the filter component 2 to form a blockage. After a period of time, the filter component The blockages on component 2 increase, affecting the filtration efficiency; thus, the self-cleaning mode needs to be turned on; under the self-cleaning mode, the liquid outlet valve 104 is in a closed or semi-closed state, the drain valve 105 is opened, and the circulating water coming out of the heat exchanger enters the beam channel 3. Since the guide body 301 reduces the cross-sectional area of the beam channel 3, the guide body 301 can guide and accelerate the circulating water, so that the circulating water close to the side wall of the beam channel 3 forms a beam flow, and improves its beam flow stability. The circulating water in the beam flow state rushes into the filter component 2 of the filter channel 1 at high speed, and flushes the surface of the filter component 2 at high speed, so that the blockages on the surface of the filter component 2 can be removed and discharged to the outside through the drain outlet 103.

[0042] In this embodiment, the liquid outlet 102 is set on the side wall of the filter channel 1, thereby forming radial filtration; the axis of the beam channel 3 and the axis of the liquid inlet 101 are both coincident with the axis of the filter assembly 2, and the inner cross-section of the beam channel 3 and the cross-section of the liquid inlet 101 are both the same as the inner cross-section of the filter assembly 2, and a guide body 301 is set in the beam channel 3. The liquid input into the beam channel 3 is guided and accelerated by the guide body 301, which increases the flow rate of the liquid and forms a beam with a high and stable flow direction. After entering the filter channel 1, the flow rate and flow direction of the liquid continue to be maintained, which can flush the blockage on the surface of the filter assembly 2 (in this process, the liquid outlet valve 104 is closed and the drain valve 105 is opened), and automatically remove the blockage on the surface of the filter assembly 2 without the need to dismantle and repair the filter screen, thereby simplifying the filter screen cleaning operation and reducing its operation time.

[0043] In one embodiment, Figure 1 and Figure 2 As shown, the axis of the flow guide 301 coincides with the axis of the beam channel 3 , that is, the flow guide 301 is arranged in the middle of the beam channel 3 .

[0044] In this embodiment, the axis of the guide body 301 is coincident with the axis of the beam channel 3, which can ensure that the guide body 301 is in a central position, thereby making the thickness of the liquid around the guide body 301 uniform, reducing the occurrence of turbulence, and improving the stability of the liquid beam, thereby improving the flushing and cleaning effect of the blockage.

[0045] In one embodiment, Figure 1 and Figure 2 As shown, the cross section of the flow guide 301 is similar to the cross section of the beam channel 3 , that is, the cross section of the flow guide 301 is a proportionally reduced cross section of the beam channel 3 .

[0046] In this embodiment, the cross-section of the guide body 301 is similar to the cross-section of the beam channel 3, so as to further improve the uniformity of the thickness of the liquid around the guide body 301 and reduce the occurrence of turbulence, thereby further improving the stability of the liquid beam and improving the flushing and cleaning effect of the blockage.

[0047] In one embodiment, the flow guide 301 extends into the filter channel 1. Specifically, the flow guide 301 can extend to the middle or tail of the filter channel 1, and can be adjusted according to actual conditions. Of course, the flow guide 301 can also be set as a retractable rod, and its specific length can be controlled by a controller.

[0048] In this embodiment, the flow guide 301 extends into the filter channel 1, which can improve the stability of the liquid beam flow and enhance the flushing and cleaning effect of the blockage.

[0049] In one embodiment, the length of the beam channel 3 is at least three times the inner diameter of the beam channel 3, that is, the length of the beam channel 3 is three times or more than the inner diameter thereof, preferably, any one of three times, four times, and five times; specifically, if the inner diameter of the beam channel 3 is 300 mm, the length of the beam channel 3 is at least 900 mm or more.

[0050] In this embodiment, the length of the beam channel 3 is at least three times the inner diameter of the beam channel 3, which can ensure the stability of the beam formed after the liquid is accelerated and guided by the guide body 301, and enhance the flushing and cleaning effect of the blockage.

[0051] In one embodiment, Figure 3 As shown, the inner wall of the filter channel 1 along its length direction is spaced apart from the filter assembly 2 , that is, a confluence space 107 is formed between the inner wall of the filter channel 1 and the filter assembly 2 .

[0052] In this embodiment, the filter channel 1 is spaced apart from the filter assembly 2 along its inner wall along the length direction, which is equivalent to forming an annular confluence space 107 on the outside of the filter assembly 2. The liquid outlet 102 is connected to the confluence space 107, so that the liquid can be filtered on the annular surface of the filter assembly 2 to improve the filtration efficiency.

[0053] In one embodiment, Figures 1 to 3 As shown, the filter assembly 2 is cylindrical. In this embodiment, the filter assembly 2 is cylindrical, which can be easily manufactured, installed and fixed.

[0054] In one embodiment, the sewage outlet 103 is contracted in a direction away from the filter channel 1 . In this embodiment, the sewage outlet 103 is contracted to facilitate communication with the sewage pipeline.

[0055] In one embodiment, Figure 3 As shown, the self-cleaning filter also includes a bypass line 4, one end of the bypass line 4 is used to communicate with the liquid inlet pipe 5, and the other end of the bypass line 4 is used to communicate with the liquid outlet pipe 6. A bypass valve 401 is provided on the bypass line 4, and a liquid inlet valve 106 is provided on the beam channel 3 for communicating with the liquid inlet pipe 5.

[0056] During operation, the self-cleaning filter is taken as an example as a part of the heat exchange system. The beam channel 3 in the self-cleaning filter is connected to the water outlet of the heat exchanger in the heat exchange system through a water pump, and the liquid outlet valve 104 is connected to the water inlet of the refrigerated hydrazine. The circulating water in the heat exchange system is circulated by the power of the water pump; one end of the bypass pipe 4 is connected to the water outlet of the water pump, and the other end is connected to the water inlet of the refrigerated hydrazine.

[0057] In the self-cleaning condition or when the beam channel 3 and the filter channel 1 are under maintenance, the liquid inlet valve 106 and the liquid outlet valve 104 are closed, and the bypass valve 401 is opened, so that the circulating water circulates from the bypass pipe 4 to ensure the normal operation of the heat exchange system.

[0058] In this embodiment, the provision of the bypass line 4 enables liquid transportation during the maintenance of the filter channel 1 and the beam channel 3 , thereby ensuring the normal progress of subsequent treatment processes.

[0059] On the other hand, the present invention also provides a system, including the beam flushing self-cleaning filter device in any of the various embodiments above.

[0060] It should be noted that the system may be a system for filtering liquid in various liquid circulation systems such as a heat exchange system.

[0061] In this embodiment, because the system includes a beam flushing self-cleaning filter device, it has the same effect as the beam flushing self-cleaning filter device, and will not be described in detail here.
