Description

Technical Field

[0001] This utility model belongs to the field of filtration technology, and in particular relates to a double-sided permeable filter barrel. Background Technology

[0002] In modern agricultural irrigation, a filtration device is usually required at the inlet of the water intake. Due to the high amount of impurities in surface water, existing technologies typically use a single-layer filter barrel. Since the water intake end is usually located on one side of the filter barrel along its length, the water flow in the filter barrel on the side furthest from the intake end is slow, resulting in lower filtration efficiency. To ensure sufficient water filtration, the overall size of the filter barrel is very large, leading to an oversized device. This causes increased deflection during use and affects the overall lifespan of the device. Therefore, how to improve filtration efficiency and extend the overall lifespan of the device is a challenging problem that those skilled in the art have been constantly considering. Utility Model Content

[0003] The purpose of this utility model is to provide a double-sided permeable filter barrel, which solves the technical problems of low filtration efficiency of the filter barrel and excessively large overall size of the filter device in the prior art, thus reducing its service life.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A double-sided permeable filter barrel includes an outer filter barrel and a left inner filter barrel and a right inner filter barrel disposed at both ends of the outer filter barrel. The ends of the left inner filter barrel and the right inner filter barrel are connected by transition connecting parts. The space between the outer filter barrel and the left and right inner filter barrels forms a backwashing space. The left and right inner filter barrels each have a left inner barrel bottom plate and a right inner barrel bottom plate, respectively, with a gap between the left inner barrel bottom plate and the right inner barrel bottom plate. The space between them forms a water collection space. The interiors of the left and right filter inner barrels form an inner barrel recessed space. A water chamber cylinder is provided in the inner barrel recessed space formed by the left filter inner barrel. The water chamber cylinder extends into the water collection space and is connected to it. A water pump connecting pipe is connected to the outside of the water chamber cylinder. The portion of the water pump connecting pipe located in the water chamber cylinder has several water suction holes in its circumference. The other end of the water pump connecting pipe is connected to or separated from the water pump. The water pump connecting pipe is rotatably connected to the side wall of the water chamber cylinder.

[0006] This utility model discloses a double-sided permeable filter barrel, wherein a backwash inlet pipe is provided at the axial center position of the left and right inner filter barrels. The connection between the backwash inlet pipe and the bottom plate of the left and right inner barrels is supported by bearings. A backwashing structure is connected in the middle of the backwash inlet pipe, and the backwashing structure flushes the backwashing space.

[0007] This utility model discloses a double-sided permeable filter barrel, wherein an impeller is provided on the bottom plate of the left inner barrel, and the impeller rotates under the impact of the water flow formed at the water inlet.

[0008] The present invention relates to a double-sided permeable filter bucket, wherein a plurality of transition filter screens are provided at the transition connection part.

[0009] This utility model discloses a double-sided permeable filter barrel, wherein the backwashing structure is provided with nozzles at corresponding positions on the outer filter barrel, the left inner filter barrel, the right inner filter barrel, and the filter screen of the transition section.

[0010] The present invention relates to a double-sided permeable filter bucket, wherein a dirt guiding structure is installed on the backwash inlet pipe at the location corresponding to the recessed space of the inner bucket, the dirt guiding structure is corresponding to the location of the backwash space, and the dirt guiding structure extends to the outside of the recessed space of the inner bucket.

[0011] The beneficial effects of this utility model are as follows: It proposes a double-sided permeable filter barrel, which, by setting double-layered concave filter barrels at both ends, allows water to enter both the outer and inner filter screens simultaneously, thereby improving filtration efficiency and filter screen permeability. This allows for a shorter filter barrel length, thus reducing the overall size and length of the device. It also reduces the impact of axial and radial forces on the rigidity of the filter barrel during use, improving the overall lifespan of the device. Furthermore, by setting a transition filter screen at the transition connection, axial water resistance is reduced, further improving filtration efficiency. The backwashing structure allows for timely flushing of the filter screen, preventing clogging and improving filtration efficiency. The inclusion of a guide structure at the corresponding position of the backwashing structure guides impurities from the backwash to the outside of the filter barrel area, preventing impurity accumulation.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] like Figure 1-4 As shown, a double-sided permeable filter barrel includes an outer filter barrel 100 and a left inner filter barrel 110 and a right inner filter barrel 120 disposed at both ends of the outer filter barrel 100. The ends of the left inner filter barrel 110 and the right inner filter barrel 120 are connected by transition connecting parts 150. The space between the outer filter barrel 100 and the left inner filter barrel 110 and the right inner filter barrel 120 forms a backwashing space 170. The left inner filter barrel 110 and the right inner filter barrel 120 respectively have a left inner barrel bottom plate 130 and a right inner barrel bottom plate 140, and there is a gap between the left inner barrel bottom plate 130 and the right inner barrel bottom plate 140. The space between the inner filter barrels 120 forms a water collection space 160. The inner barrel recesses 300 are formed inside the left inner filter barrel 110 and the right inner filter barrel 120. A water chamber cylinder 500 is provided in the inner barrel recess 300 formed by the left inner filter barrel 110. The water chamber cylinder 500 extends into the water collection space 160 and is connected to it. A water pump connecting pipe 600 is connected to the outside of the water chamber cylinder 500. The portion of the water pump connecting pipe 600 located in the water chamber cylinder 500 has several water suction holes 610 in its circumferential direction. The other end of the water pump connecting pipe 600 is connected to or separated from a water pump. The water pump connecting pipe 600 is rotatably connected to the side wall of the water chamber cylinder 500.

[0019] It should be noted that by setting up a layered filter barrel, water can enter the backwashing space 170 from the filter screen holes set in the outer filter barrel 100, the left inner filter barrel 110 and the right inner filter barrel 120, thereby collecting the filtered water into the water collection space 160, so that the filtered water enters the water chamber cylinder 500, and then enters the water pump connecting pipe 600 through the water suction hole 610 for suction.

[0020] In a preferred embodiment, a backwash inlet pipe 200 is provided at the axial center position of the left filter inner barrel 110 and the right filter inner barrel 120. The connection between the backwash inlet pipe 200 and the bottom plate 130 of the left inner barrel and the bottom plate 140 of the right inner barrel is supported by bearings. A backwashing structure 400 is connected in the middle of the backwash inlet pipe 200, and the backwashing structure 400 flushes the backwashing space 170.

[0021] It should be noted that the structure of this application is supported by a frame and lies horizontally in the water, with one part exposed on the water surface, which makes it easy to clean the attached impurities, and the external filter 100 can rotate around the backwash water pipe 200 as the pivot.

[0022] In a preferred embodiment, an impeller is provided on the bottom plate 130 of the left inner barrel, and the impeller rotates under the impact of the water flow formed at the water inlet 610.

[0023] By designing this structure, the water flow changes caused by water suction and extraction drive the impeller to rotate, thereby causing the outer filter barrel 100 to rotate. The water pump connecting pipe 600 and the backwash pipe 200 are fixed structures, forming a rotating shaft. This ensures that all parts of the filter barrel are evenly flushed by the backwash structure 400, thus maintaining unobstructed flow.

[0024] In a preferred embodiment, a plurality of transition filters 151 are provided at the transition connection portion 150.

[0025] In such a structure, where the filter screen is also installed in the thickness direction of the layer structure, it can be that several holes are opened in the middle of the annular plate and the filter screen is installed in the holes, or it can be set as an annular opening and the filter screen is installed in the annular opening. It should be noted that if it is set in an annular opening, a support structure should be set at intervals at the opening to ensure the strength of the annular opening.

[0026] In a preferred embodiment, the backwashing structure 400 is provided with nozzles 410 at corresponding positions on the outer filter barrel 100, the left inner filter barrel 110, the right inner filter barrel 120, and the transition filter screen 151.

[0027] This structure allows all the filter parts of the filter canister to be flushed, thus maintaining filtration capacity and efficiency.

[0028] In a preferred embodiment, a dirt-guiding structure 700 is installed on the backwash inlet pipe 200 at the location corresponding to the inner tub recessed space 300. The dirt-guiding structure 700 corresponds to the location of the backwash space 170 and extends to the outside of the inner tub recessed space 300.

[0029] It should be noted that the backwash structure 400 is usually located at the top, so that the outer filter box 100 can be rinsed evenly during rotation, and the rinsed part is not immersed in water. A dirt-blocking structure is usually set in this area to prevent floating impurities on the water surface from approaching the filter box. Furthermore, the dirt-guiding structure can collect and guide the rinsed impurities to prevent secondary pollution of the water source around the filter box.
