Description

Technical Field

[0001] The present application relates to the technical field of grille dirt removers, and in particular to an inner-flow grille dirt remover. Background Art

[0002] The internal flow screen cleaner is formed by a continuously rotating screen driven by a motor placed in a fixed frame. The sewage to be filtered enters from the opening in the middle of the screen, passes through the screens on both sides from the inside to the outside to filter out impurities, and then flows out. The filter screen belt rotates at the same time, and the impurities deposited on the inside of the screen are lifted by the lifting plate on the screen to the top screen residue discharge area, and are washed into the screen residue collection tank by the washing water, and discharged by the built-in screw conveyor.

[0003] The Chinese patent with publication number CN210237167U discloses an internal inlet screen dirt remover, with a water blocking plate on the outside of the frame, a mesh plate chain inside, a placement area on the top, a water inlet on one side of the frame, and a water outlet on the other side. A movable plate is placed inside the chute and connected to the chute through a soft film. The other end of the electric push rod is fixedly connected to the chute. By moving the electric push rod, the debris inside the chute can be controlled to be squeezed, thereby filtering and discharging the debris in the sewage.

[0004] With regard to the above-mentioned related technologies, the water outlet flushes the grille to separate and remove impurities, but some impurities may not be successfully washed away by the water flow and remain on the inner wall of the grille, which may easily cause the grille to be blocked, thus resulting in deficiencies. Utility Model Content

[0005] In order to clean the residual impurities on the grille, the present application provides an inner flow grille cleaner.

[0006] The present application provides an internal inlet grille decontamination machine that adopts the following technical solution:

[0007] An internal inlet grid dirt remover comprises a frame, one side of the frame is provided with a water inlet, the frame is closed relative to the other side of the water inlet, two oppositely arranged conveying chains are rotatably provided on the frame, a filter grid belt is provided between the two conveying chains, a cleaning mechanism for cleaning the filter grid belt is provided in the frame, and a sewage discharge device for recovering impurities is provided on one side of the cleaning mechanism.

[0008] By adopting the above technical solution, sewage flows in from one end of the water inlet. Since the other side of the frame is closed, the sewage can only flow out from the filter grille belts on both sides of the frame. When impurities in the sewage contact the filter grille belts, the impurities are stuck in the gaps of the filter grille belts under the thrust of the liquid flow. The reduction motor drives the filter grille belt to transmit, and the impurities on the filter grille belt are removed by the cleaning mechanism and fall into the sewage discharge device, thereby achieving filtering and cleaning of the sewage.

[0009] Optionally, the cleaning mechanism includes a flushing water pipe, on which a plurality of flushing heads are provided, and the flushing heads are arranged toward the filter grid belt.

[0010] By adopting the above technical solution, sewage flows through the frame, and the filtered water flows out from both sides of the filter grille belt. The filtered water can be directly passed into the flushing water pipe through the water pump, and then flows to the filter grille belt through the flushing head. The flushing head flushes toward the outside of the filter grille belt, and the impurities are washed down to the sewage discharge device by the impact force of the water flow.

[0011] Optionally, a reduction motor is provided on the frame, a transmission gear is rotatably provided on the rotating shaft of the reduction motor, a cleaning brush rod is provided on the frame, a connecting gear meshing with the transmission gear is provided at the end of the cleaning brush rod, and the side wall of the cleaning brush rod contacts the inner wall of the filter grille belt.

[0012] By adopting the above technical solution, after flushing, residual impurities will be entrained on the filter grille belt, the transmission gear will mesh with the connecting gear, and the reduction motor will rotate while driving the cleaning brush rod to rotate. At this time, the cleaning brush rod and the filter grille belt have opposite rotation directions, and the filter grille belt continues to be transmitted upward. The cleaning brush rod contacts the filter grille belt and brushes the impurities off onto the sewage discharge device, thereby improving the filtering effect of the device.

[0013] Optionally, the sewage discharge device includes a sewage discharge pipe, which is placed in the frame and is arranged to be inclined downward along the length direction of the sewage discharge pipe. A water outlet connected to the sewage discharge pipe is opened on one side of the frame, and the filter grid belt is sleeved on the outside of the sewage discharge pipe.

[0014] By adopting the above technical solution, impurities fall into the sewage pipe and flow out along the sewage pipe along with the sewage. By designing the sewage pipe to be inclined, the impurities falling into the sewage pipe will flow out along the inclined direction, reducing the possibility of impurities accumulating on the sewage pipe.

[0015] Optionally, the filter grid belt (6) is evenly provided with movable plates (16) along the travel direction of the filter grid belt (6), and the movable plates (16) are L-shaped.

[0016] By adopting the above technical solution, sewage flows into the rack, and some impurities accumulate at the bottom of the rack. By setting a movable plate, when the movable plate moves, the strip-shaped or flocculent impurities on the filter grille belt will hang on the L-shaped movable plate. When the movable plate rises with the filter grille belt and passes over the top of the rack, the impurities will fall onto the sewage pipe, which is beneficial to improve the filtering effect.

[0017] Optionally, both sides of the frame (1) are provided with plug-in blocks (18) arranged opposite to the movable plate (16), and the movable plate (16) has a connecting rod (17) inserted therein, and both ends of the connecting rod (17) are inserted into the plug-in blocks (18) and are in rotational contact with the plug-in blocks (18), and both ends of the connecting rod (17) are sleeved with torsion springs (19), one end of the torsion spring (19) is fixedly connected to one end of the movable plate (16), and the other end is fixedly connected to the plug-in block (18).

[0018] By adopting the above technical solution, the movable plate is rotatably connected to the filter grille belt through a torsion spring. The filter grille belt drives the movable plate to move while being transmitted. Since the cleaning brush rod is fixed, when the cleaning brush rod contacts the movable plate, the movable plate flips over and the impurities dropped on the movable plate are knocked into the sewage pipe.

[0019] Optionally, a water pump is provided on the frame, a hose is connected to the water outlet of the water pump, the hose is connected to the flushing water pipe, a water pump is provided at the water inlet of the water pump, and the other end of the water pump is connected to filtered water.

[0020] By adopting the above technical solution, the sewage filtered by the filter grille belt flows out from one side of the frame, the water pump draws out the filtered water through the suction pipe, and discharges it into the flushing water pipe through the hose and then sprays it onto the filter grille belt to achieve cleaning and water resource reuse.

[0021] Optionally, an inspection opening is provided on the side wall of the frame, and a slide plate is slidably provided on the inspection opening.

[0022] By adopting the above technical solution, the inspection port is set on one side of the rack, which is convenient for the staff to check the internal working status. When the inside of the rack needs to be inspected and cleaned, it is only necessary to slide the slide to one side, which is convenient for subsequent staff to clean and inspect the inside of the rack.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting a reduction motor, a cleaning brush rod, a transmission gear and a connecting gear, the transmission gear and the connecting gear are meshed with each other. When the reduction motor is running, the transmission direction of the cleaning brush rod and the filter grille belt is opposite. The bristles on the cleaning brush rod always contact the filter grille belt. When the filter grille belt is driven, the cleaning brush rod cleans the impurities attached to the filter grille belt, which is beneficial to improve the filtering effect of the device;

[0025] 2. By setting a movable plate and a torsion spring, sewage flows in from the water inlet, and the flushing head flushes the filter grille belt to flush off some impurities. Some impurities will fall onto the movable plate under the action of gravity. At this time, the filter grille belt is driven, and the movable plate will contact the cleaning brush rod. Under the action of the torsion spring, the L-shaped movable plate will flip over, and the attached impurities will be brushed off by the cleaning brush rod. In addition, when the movable plate contacts the cleaning brush rod, it is conducive to cleaning the cleaning brush rod, which is beneficial to improving the filtration efficiency.

The protective cover 22 is arranged on the outside of the transmission gear 13 and the connecting gear 15. A cleaning brush rod 14 is rotatably arranged on the frame 1, and a connecting gear 15 is fixedly arranged at one end of the cleaning brush rod 14, and the connecting gear 15 is rotatably connected to the frame 1. The transmission gear 13 and the connecting gear 15 are meshed with each other. During operation, the side wall of the cleaning brush rod 14 contacts the inner wall of the filter grille belt 6.

[0037] Reference Figure 3 A plurality of movable plates 16 arranged along the length direction of the frame 1 are rotatably provided on the filter grid belt 6, and a plurality of movable plates 16 are erected between the two conveying chains 5. The movable plates 16 are evenly arranged in the movement direction of the filter grid belt 6, and the movable plates 16 are L-shaped. Plug-in blocks 18 arranged opposite to the movable plates 16 are fixedly provided on both sides of the frame 1.

[0038] The implementation principle of an internal inlet screen dirt remover in the embodiment of the present application is as follows: the length direction of the frame 1 is parallel to the direction of water flow, so that water can flow in from the water inlet 2, and the reduction motor 3 is started. The reduction motor runs more stably under the support of the support frame 23, and the reduction motor drives the transmission wheel 4 to rotate, and the transmission wheel 4 drives the transmission chain 5 to run. At this time, the filter screen belt 6 moves along the running direction of the transmission chain 5. After the liquid enters from the water inlet 2, due to the closure on the opposite side of the water inlet 2 on the frame 1, the water can only flow out from the filter screen belts 6 on both sides. When the solid impurities in the sewage contact the filter screen belt 6, they will be stuck in the gap of the filter screen belt 6 and move with the filter screen belt 6. During the movement, some impurities will fall onto the movable plate 16 under the action of gravity. Since the movable plate 16 is L-shaped, it is not easy for the impurities to fall from the movable plate 16.

[0039] At this time, water is sucked into the flushing water pipe 10 through an external water pump and rushed toward the filter grille belt 6 along the flushing head 11. The sewage carrying impurities falls into the drain pipe 12. Since the drain pipe 12 is inclined, it is not easy to be blocked and flows smoothly. Then the sewage carrying impurities flows out from the water outlet 20. Since the transmission gear 13 and the connecting gear 15 are meshed with each other, the cleaning brush rod 14 and the transmission direction of the filter grille belt 6 are opposite. Since the protective cover 22 is set, the transmission gear 13 and the connecting gear 15 are safer and more stable during operation. The impurities remaining on the filter grille belt 6 will be swept into the drain pipe 12 by the cleaning brush rod 14. When the cleaning brush rod 14 contacts the movable plate 16, the movable plate 16 is flipped under the action of the torsion spring 19, and the cleaning brush rod 14 sweeps the impurities on the movable plate 16 into the drain pipe 12. Then, there are residual impurities on the movable plate 16. When the movable plate 16 moves and passes over the top of the frame 1, the impurities on the movable plate 16 will fall into the drain pipe 12. In addition, the sliding plate 9 is arranged to facilitate the staff to observe the internal situation from the inspection port 8, and it is convenient for the staff to carry out inspection when problems are found.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
