The invention is a self-cleaning filter assembly with at least one filter inlet (1a), at least one 5 At least one main trunk (1a) containing the main outlet (1b) and at least one bypass outlet (1e) and the aforementioned at least one steering system containing at least one wing (2a) located inside the main body (1) (2) and contains at least one filter (3). According to the technical specifications and operating principle of the filter assembly that is the subject of the invention, 10 The application location must be a two-part pump system connected by interconnection. The filter subject to the invention... It can be easily adapted to installations with high flow rates where refilling is possible. Preferably Suitable for use in fire pumps containing two different pressure units, depending on the area of ​​application. There are no relevant limitations. An example application of the invention is shown in Figure 1. In the representative image, the normal pressure unit (4) and the high pressure unit 15 are on the same pump. (5) is shown as a system in which the invention is located. In the said image, the filter in question is shown. the fluid flowing between the mentioned normal pressure unit (4) and high pressure unit (5) the process of filtering solid particles of a certain size (6) found within it It is carrying out. The filter assembly subject to the invention includes at least one filter chamber (1c), a strainer (3) and The router (2) is located in the aforementioned filter chamber (1c). The aforementioned main The filter housing (1c), the guide (2) and the strainer (3) are held together inside the housing (1). It is a part. The main body (1) preferably has a shape similar to the letter 'Y'. In the filter assembly that is the subject of the invention, the main outlet (1b) contained in the main body (1) is the filtering process. It is for the finished fluid. The main outlet mentioned (1b) is to the high pressure unit (5) connected and outlet section where water free of solid particles (6) is obtained is happening. All inlets and outlets on the main body (1) can be fitted with hoses or pipes, as preferred. This can be accomplished with a transfer element. There are no limitations regarding this. It is not available. The router (2) is fixed at the filter inlet (1a) to prevent it from rotating and is fixed to the main body (1) It is positioned against the direction of flow of water entering the part. The mentioned diverter (2) The front part is preferably conical in shape so as not to obstruct the flow of water. Diverter (2) It has at least one fin (2a) on it, and the water reaching the router (2) is the aforementioned most The flow direction is gained by a small vane (2a). In the water filter assembly, vane 5 It is possible to pass behind the router (2) without gaining flow direction by (2a). These vanes (2a) are preferably similar in shape to the vanes of gas turbines. They are similar. The correct functioning of the filter assembly, which is the subject of the invention, and the pressure that may occur... and in order to minimize speed losses, the shape of this guide (2) is the fin (2a) The number and angle of the winglets (2a) are of great importance. 10 of the mentioned winglets (2a) The colliding fluid, under the influence of its initial velocity, moves in a vortex-like circular motion. meeting and flowing toward the filter chamber (1c) with a force against the inner walls of the strainer (3) It begins. In the system where the filter device that is the subject of the invention is used, the router (2) Its purpose is to give the fluid a swirling, vortex-like circular motion that causes it to move forward by rotating, and The aim is to prevent the fluid from going directly to the bypass outlet (1e). 15 The filter device in question is placed behind the router (2) for the filtering process. There is a filter (3) with at least one hole (3a) installed. This filter (3) is shown in the figure. It preferably resembles a cylinder open at the top and bottom. The mentioned The filter holes (3a) allow the fluid to pass through while retaining solid particles (6), 20 It holds the solid to be filtered in the filter (3). The diameter of the filter holes (3a) is the diameter of the solid to be filtered. can be adjusted according to the size of the particles (6) and the characteristics of the system in which it will be used There are no limitations regarding this. Filtered water passes through the filter. (3) There is an angular difference between the flow direction and the flow inside the filter chamber (1c). This Thanks to the difference, the water passing through the filter (3) moves in a different direction, while the water passing through the filter (3) 25 Solid particles that could not pass (6) continue their flow without changing direction. In the filter device that is the subject of the invention, solid particles (6) that cannot pass through the filter holes (3a) and A portion of the fluid is discharged using the bypass outlet (1e) located in the main body (1), at normal pressure. It is sent back to unit (5). 30 In the known state of the art, dirt-catching filters do not have a guide (2), filter Water entering from the inlet (1a) flows directly into the filter chamber (1c) and passes through the strainer (3). In addition, the second such as the bypass output (1e) mentioned here is available in the known state filters. 6 There is no outlet; instead, there is a cover here. Filter cleaning, however... This is accomplished by opening the lid here. The path followed by the fluid in the filter assembly, which is the subject of this invention, is shown in the circuit diagram in Figure 1. The paths shown are A, B, C, D, E, F in that order. The fluid to be filtered is 5. First, come to the normal pressure unit (4) as shown by A, and here It is pressurized and the fluid flows into two paths, B and C, at the outlet of the normal pressure unit (4). It is separated. A portion of the pumped fluid is used in the system at this pressure. While continuing on its way, the remaining amount is transferred to the high pressure unit (5). The fluid to be filtered enters through the filter inlet (1a) and goes to the main body (1). As the guide moves between the vanes (2) (2a) of the guide, these vanes (2a) swirl the fluid. This gives the fluid a similar circular motion. The fluid, having acquired this motion, enters the filter chamber. (1c) enters and flows by turning on the inner surfaces of the strainer (3) located in the filter chamber (1c). The size of the solid particles (6) in the fluid starts with the hole (3) of the filter. If the solid particles (6) are larger than the diameters (3a), they remain inside the main body (1). 15 The fluid moves by rotating on the inner surfaces of the filter (3) and at the same time through the filter holes. (3a) is filtered. The filtered fluid goes to the high pressure unit (5) via path D. It enters and then exits via route E. As the fluid moves in a circular motion inside the filter (3), the direction in which the filtered fluid will go, It remains perpendicular to the direction in which the fluid enters the filter chamber (1c). In this way, the filtered fluid 20 While flowing perpendicular to the center of the cylindrical filter (3), the solid that cannot be filtered particles (6) and some fluid move through the filter (3) without changing direction. It continues and reaches the bottom of the filter housing (1c). From there, it passes through the bypass hole. (1d) passes through and proceeds towards the bypass exit (1e). Unfilterable solid particles (6) Moving forward without changing direction prevents the accumulation of solid particles (6) inside the filter (3), 25 The clogging of the filter holes (3a) is prevented. The fluid entering the main body (1) is vortexed. Because of the way of movement, the non-hard solid particles (6) hit the filter holes (3a) It can be broken down and after being broken down it can pass through the filter holes (3a). The water coming out of the router (2) swirling around gets caught in the filter holes (3a). Because the filter sweeps away the solid particles (6) and drags them to the bypass outlet (1e), the filter 30 There is no clogging on the holes (3a). The filtered fluid passes through the strainer holes. (3a) a fluid filter carrying solid particles (6) and solid particles (6) as it passes through It moves towards the bottom of the reservoir (1c), passes through the bypass hole (1d) and bypass It returns to the normal pressure unit (4) via the path indicated by F through the outlet (1e). 7 For the filter assembly to function properly, the diameter of the bypass hole (1d) must match the diameter of the main body (1). It must not be larger than the diameter of the outlet (1b). The bypass outlet (1e) will be filtered. The normal pressure unit (4) from which the fluid comes is connected to the inlet. Industrial Applicability of the Invention The invention is a two-section system operating on the principles of centrifugal pumps for the purpose of conveying water. The 10 in the water flowing from the normal pressure section to the high pressure section in the pumps solid particles self-destruct without any maintenance or replacement required. It relates to a filter assembly capable of cleaning and is suitable for industrial use. The invention is not limited to the above descriptions; a person skilled in the field can easily create the invention. It can present different applications. These are the claims of the invention and the protection requested. 15 should be evaluated within this context. 25
