Description

Technical Field

[0001] This invention relates to the field of river filtration technology, and in particular to a rotating filter screen equipped with an electrically controlled translation mechanism. Background Technology

[0002] A rotary filter is a filtration device used in river water, primarily installed on the inlet side of the river. Its structure consists of a drive unit installed above the water level, a transmission system, a screen and chain, guide rails, a flushing water system, and an electrical control system. When water flows over the screen, impurities in the water are intercepted. Then, by timed activation, the screen rotates and rises, lifting the impurities to the ground for easy cleaning from the top.

[0003] Rotary filters can only filter a single flow channel during use, which greatly limits their applicable scenarios. Moreover, due to the limitation of the filtration method, the operability of the river channel is fixed, which seriously affects its use in different situations. Summary of the Invention

[0004] The technical problem that this invention aims to solve is that current rotating filters can only filter a single flow channel, which limits their applicable scenarios. Moreover, due to the limitation of the filtration method, the operability of the river channel is fixed, which seriously affects its use in different situations.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a rotating filter screen with an electrically controlled translation mechanism, including a top crossbeam installed at the upper opening of the river channel and a bottom limiting frame fixed at the bottom of the river channel. An upper translation guide rail is fixedly assembled at the lower end of the top crossbeam, and a lower translation guide rail is installed inside the bottom limiting frame. A first electrically controlled translation flipping frame and a second electrically controlled translation flipping frame are arranged between the upper and lower translation guide rails. An electrically controlled rotating filter screen is assembled inside both the first and second electrically controlled translation flipping frames.

[0006] The first and second electrically controlled translation and flipping frames each consist of a first adjusting slider slidably installed inside the upper translation guide rail, a second adjusting slider slidably installed inside the lower translation guide rail, a flipping adjustment frame movably installed between the first and second adjusting sliders, a first flipping support rod movably installed on the backwater side of the upper translation guide rail, and a second flipping support rod movably installed on the backwater side of the lower translation guide rail.

[0007] The upper translation guide rail is internally fitted with a first translation screw that is threadedly assembled with the first adjusting slider, and the lower translation guide rail is internally fitted with a second translation screw that is threadedly assembled with the second adjusting slider.

[0008] The electrically controlled rotating filter screen includes a top drive wheel, a side driven wheel, an external drive belt, an external filter frame mounted on the external drive belt, and a drive motor fixed inside the rotating adjustment frame.

[0009] The lower translational guide rail has a discharge port with a lateral opening on its backwater surface.

[0010] The upper part of the lower translational guide rail is elastically fitted with an upper guide plate on the water-facing surface.

[0011] The flipping adjustment frame has arc-shaped control rods on both the backwater surface and the lower end, which are movably connected to the first flipping support rod and the second flipping support rod.

[0012] An electrically controlled telescopic scraper is installed on the side wall of the top crossbeam.

[0013] Both the top crossbeam and the bottom limiting frame are fixed with lateral support frames.

[0014] A top protective cover is fixedly installed at the upper end of the top crossbeam.

[0015] The beneficial effects of this invention are:

[0016] (1) The rotating filter screen with an electrically controlled translation mechanism of the present invention adopts a two-stage structure design, which can switch states according to the needs of the scenario, thus greatly improving its applicability to various scenarios;

[0017] (2) By adopting electronically controlled translation and flipping adjustment, the angle and position of the rotating filter screen can be controlled, making operation more convenient;

[0018] (3) By adopting the design of top crossbeam and bottom limiting frame, the impact resistance of the entire rotating filter screen can be enhanced, making its structure more robust and stable;

[0019] (4) The rotating filter screen can be quickly attached to both sides of the river by disassembly. It can not only switch the filtration mode, but also change the obstruction inside the main river channel, making it easier for the internal ecology to pass through and improving different application scenarios.

[0020] (5) The angle of the rotating filter screen is changed by flipping the support rod, making the adjusted structure more stable;

[0021] (6) It adopts a two-stage independent operation structure design, which can rotate according to the filtration requirements of different positions, making the operation more flexible and efficient. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Figure 1 , Figure 2 , Figure 3 and Figure 4 The rotating filter screen shown includes a top beam 1 installed at the upper opening of the river channel and a bottom limiting frame 2 fixed to the bottom of the river channel. An upper translation guide rail 3 is fixedly mounted at the lower end of the top beam 1. A lower translation guide rail 4 is installed inside the bottom limiting frame 2. A first electrically controlled translation flipping frame 5 and a second electrically controlled translation flipping frame 6 are arranged between the upper translation guide rail 3 and the lower translation guide rail 4. An electrically controlled rotating filter screen 7 is installed inside both the first electrically controlled translation flipping frame 5 and the second electrically controlled translation flipping frame 6.

[0030] Working principle: When it is a unidirectional river, the first electrically controlled translational flipping frame 5 and the second electrically controlled translational flipping frame 6 are flipped into a single-sided filter screen. At this time, the electrically controlled rotating filter screen 7 on the first electrically controlled translational flipping frame 5 and the second electrically controlled translational flipping frame 6 simultaneously filters the fluid inside the river. When it is a multi-channel river, it is flipped backward and then translated outward to perform lateral filtration, so that it has a multi-channel filtration function.

[0031] To facilitate translation and flipping adjustments, both the first electrically controlled translation and flipping frame 5 and the second electrically controlled translation and flipping frame 6 consist of a first adjusting slider 561 slidably installed inside the upper translation guide rail 3, a second adjusting slider 562 slidably installed inside the lower translation guide rail 4, a flipping adjustment frame 563 movably installed between the first adjusting slider 561 and the second adjusting slider 562, a first flipping support rod 564 movably installed on the backwater side of the upper translation guide rail 3, and a second flipping support rod 565 movably installed on the backwater side of the lower translation guide rail 4.

[0032] To facilitate translation control, the upper translation guide rail 3 is internally fitted with a first translation screw 8 that is threadedly fitted to the first adjusting slider 561, and the lower translation guide rail 4 is internally fitted with a second translation screw 9 that is threadedly fitted to the second adjusting slider 562.

[0033] The first translation screw 8 and the second translation screw 9 rotate synchronously, thereby controlling the first adjusting slider 561 to perform translation adjustment along the upper translation guide rail 3, and controlling the second adjusting slider 562 to perform translation adjustment along the lower translation guide rail 4.

[0034] To facilitate driving and adjustment, the electrically controlled rotating filter 7 includes a top drive wheel 71 mounted on the flip adjustment frame 563, a side driven wheel 72, an external drive belt 73, an external filter frame 74 mounted on the external drive belt 73, and a drive motor 75 fixed inside the flip adjustment frame 563.

[0035] The drive motor 75 drives the top drive wheel 71 to rotate, thereby controlling the external drive belt 73 to operate and adjust along the top drive wheel 71 and the side driven wheel 72. During the adjustment process, the external filter frame 74 is moved synchronously to discharge the filtered material on its surface upward.

[0036] To prevent internal impurities from accumulating and to facilitate the removal of internal impurities, a discharge port 10 with a side opening is provided on the backwater surface of the lower horizontal guide rail 4.

[0037] By opening a discharge port 10 on the backwater surface of the lower translation guide rail 4, impurities falling into the lower translation guide rail 4 will be discharged from the discharge port 10 with the water flow; they can also be discharged from the discharge port 10 after being squeezed by the second adjusting slider 562.

[0038] To facilitate control of the bottom sludge guide filter port, an upper guide plate 11 is elastically fitted on the upper end of the water-facing surface of the lower translational guide rail 4.

[0039] By diverting the flow upwards at an angle, silt can be prevented from flowing into the lower translational guide rail 4 to a certain extent, reducing the difficulty of later maintenance.

[0040] To facilitate the flipping control, the flipping adjustment frame 563 has arc-shaped control rods 12 on both the upper and lower ends of the backwater surface, which are movably connected to the first flipping support rod 564 and the second flipping support rod 565.

[0041] The first tilting support rod 564 is connected to the movable shaft of the arc-shaped control rod 12 at the upper end of the backwater surface of the tilting adjustment frame 563, while the second tilting support rod 565 is connected to the movable shaft of the arc-shaped control rod 12 at the lower end of the backwater surface of the tilting adjustment frame 563. The angle adjustment of the tilting adjustment frame 563 is controlled by the first tilting support rod 564 and the second tilting support rod 565.

[0042] To facilitate the scraping of impurities from the electronically controlled rotating filter screen 7 at the top, an electronically controlled telescopic scraper plate 13 is installed on the side wall of the top beam 1.

[0043] The electrically controlled telescopic scraper 13 includes an inclined guide rail fixed on the side wall of the top beam 1, a built-in screw movably installed inside the inclined guide rail, and a telescopic scraper with internal thread control blocks on both sides. The telescopic scraper slides along the inclined guide rail by rotating the built-in screw. The bottom of the telescopic scraper is close to the surface of the electrically controlled rotating filter screen 7, so that the impurities on the surface of the electrically controlled rotating filter screen 7 are scraped off. Then, the impurities are scraped off upward by the inclined telescopic scraper and then discharged outward through the guide groove located inside the horizontal beam 1.

[0044] To complement the lateral support and improve the lateral support of the electrically controlled rotating filter screen 7 after it flips over, lateral support frames 14 are fixed on both sides of the top crossbeam 1 and the bottom limiting frame 2.

[0045] The lateral support frame 14 can also ensure the structural stability between the top beam 1 and the bottom limiting frame 2, and can also ensure the stability and airtightness of the ends of the electrically controlled rotating filter screen 7 after it is flipped on both sides.

[0046] To enhance the safety of the top structure, a top protective cover 15 is fixedly installed on the upper end of the top beam 1.

[0047] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
