Description

Technical Field

[0001] The invention relates to the technical field of river filtration, in particular to a rotary filter screen with an electrically controlled translation mechanism. Background Art

[0002] The rotary filter is a filtering device used for river water. It is mainly arranged on the water inlet side of the river. Its structure consists of a drive device installed above the water level, a transmission system, a mesh plate and chain, a guide rail, a flushing water system, an electronic control system, etc. When the water flows through the mesh surface, the dirt in the water flow is intercepted. Then, the mesh plate is rotated and raised by timing the operation, thereby lifting the dirt to the ground, which is convenient for cleaning the dirt on the top.

[0003] During use, the rotary filter can only filter a single flow channel, which makes its application scenarios very limited. Moreover, due to the limitation of the filtering 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 to be solved by the present invention is that the current rotary filter can only filter a single flow channel, which makes its application scenarios very limited. Moreover, due to the limitation of the filtering 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 problems is: a rotating filter screen with an electrically controlled translation mechanism, comprising an upper crossbeam installed at the upper end opening of a river channel and a lower limit frame fixed to the bottom of the river channel, an upper translation guide rail is fixedly installed at the lower end of the upper crossbeam, a lower translation guide rail is installed inside the bottom limit frame, a first electrically controlled translation flip frame and a second electrically controlled translation flip frame are arranged between the upper translation guide rail and the lower translation guide rail, and an electrically controlled rotating filter screen is installed inside the first electrically controlled translation flip frame and the second electrically controlled translation flip frame.

[0006] The first electrically-controlled translation and flipping frame and the second electrically-controlled translation and flipping frame are both composed of a first adjusting slider slidably installed inside an upper translation guide rail, a second adjusting slider slidably installed inside a lower translation guide rail, a flipping adjustment frame axially movably installed between the first adjusting slider and the second adjusting slider, a first flipping support rod movably installed on the back side of the upper translation guide rail, and a second flipping support rod movably installed on the back side of the lower translation guide rail.

[0009] A discharging port with a lateral opening is provided on the back surface of the lower translation guide rail.

[0010] An upper guide plate is elastically mounted on the upper end of the water-facing surface of the lower translation guide rail.

[0011] The upper and lower ends of the flip adjustment frame on the back surface of the water are both provided with arc-shaped control rods movably connected with the first flip support rod and the second flip support rod.

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

[0013] Lateral support frames are fixed on both sides of the top crossbeam and the bottom limit frame.

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

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Figure 1 , Figure 2 , Figure 3 and Figure 4 The rotary filter screen with an electrically controlled translation mechanism shown in the figure comprises an upper crossbeam 1 installed at the upper opening of the river channel and a lower limit frame 2 fixed at the bottom of the river channel, an upper translation guide rail 3 is fixedly installed at the lower end of the upper crossbeam 1, a lower translation guide rail 4 is installed inside the bottom limit frame 2, a first electrically controlled translation flip frame 5 and a second electrically controlled translation flip frame 6 are arranged between the upper translation guide rail 3 and the lower translation guide rail 4, and an electrically controlled rotating filter screen 7 is installed inside the first electrically controlled translation flip frame 5 and the second electrically controlled translation flip frame 6.

[0030] Working principle: When it is a single-flow river channel, the first electrically-controlled translational flip frame 5 and the second electrically-controlled translational flip frame 6 are flipped over to become a single-sided filter net. At this time, the electrically-controlled rotating filter net 7 on the first electrically-controlled translational flip frame 5 and the second electrically-controlled translational flip frame 6 simultaneously filters the fluid inside the river channel. When it is a multi-channel river channel, this is done by flipping backwards and then translating outwards to perform lateral filtering, so that it has a multi-channel filtering function.

[0031] In order to cooperate with the translation and flipping adjustment, the first electrically-controlled translation and flipping frame 5 and the second electrically-controlled translation and flipping frame 6 are both composed 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 axially movably installed between the first adjusting slider 561 and the second adjusting slider 562, a first flipping support rod 564 movably installed on the back side of the upper translation guide rail 3, and a second flipping support rod 565 movably installed on the back side of the lower translation guide rail 4.

[0032] In order to cooperate with translation control, the upper translation guide rail 3 is movably equipped with a first translation screw 8 threadedly assembled with the first adjustment slider 561, and the lower translation guide rail 4 is movably equipped with a second translation screw 9 threadedly assembled with the second adjustment slider 562.

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

[0034] In order to cooperate with driving and adjustment, the electrically controlled rotary filter 7 includes a top driving wheel 71 installed on the flip adjustment frame 563, a side driven wheel 72, an external driving belt 73, an external filter frame 74 installed on the external driving belt 73 and a driving motor 75 fixed inside the flip adjustment frame 563.

[0035] The driving motor 75 drives the top driving wheel 71 to rotate, thereby controlling the external driving belt 75 to operate and adjust along the top driving wheel 71 and the side driven wheel 72, and synchronously drives the external filter frame 74 to move during the adjustment process to guide the filtered material on its surface upward.

[0036] In order to avoid the accumulation of internal impurities and facilitate the discharge of internal impurities, a discharge port 10 with a lateral opening is opened on the back surface of the lower translation guide rail 4.

[0037] By opening a discharge port 10 on the back 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 along with the water flow; they can also be discharged from the discharge port 10 after the second adjusting slider 562 slides and squeezes.

[0038] In order to facilitate the control of the sludge guiding filter port at the bottom, an upper guide plate 11 is elastically mounted on the upper end of the water-facing surface of the lower translation guide rail 4 .

[0039] By diverting the flow obliquely upward, it is possible to prevent silt from flowing into the lower translation guide rail 4 to a certain extent, thereby reducing the difficulty of subsequent maintenance.

[0040] In order to cooperate with the flip control, the flip adjustment frame 563 has an arc-shaped control rod 12 movably connected to the first flip support rod 564 and the second flip support rod 565 on the upper and lower ends of the back water surface.

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

[0042] In order to conveniently scrape away the impurities on the electrically-controlled rotary filter screen 7 at the top, an electrically-controlled retractable scraper plate 13 is installed on the side wall of the top crossbeam 1 .

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

[0044] In order to cooperate with the lateral support and improve the lateral support of the electrically-controlled rotary filter screen 7 after flipping, lateral support frames 14 are fixed on both sides of the top crossbeam 1 and the bottom limit frame 2.

[0045] The lateral support frame 14 can also ensure the structural stability between the top crossbeam 1 and the bottom limit frame 2, and can ensure the stability and airtightness of the ends of the electrically-controlled rotary filter screen 7 after flipping over on both sides.

[0046] In order to improve the safety of the top structure, a top protective cover shell 15 is fixedly mounted on the upper end of the top crossbeam 1 .

[0047] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
