Technical Field

[0001] This invention relates to the field of pollution removal technology, and in particular to a circulating environmentally friendly mechanical bar screen cleaner. Background Technology

[0002] In municipal and industrial wastewater treatment, circulating environmental mechanical bar screens continuously intercept and remove suspended solids from the influent through rotating bar screens. However, the removed debris (long fibers or plastic films) easily entangles or adheres to the surface of the cleaning components and is not thoroughly removed by the scrapers. These accumulated debris gradually thicken, causing bar screen deformation or blockage of the bar gaps, ultimately reducing equipment efficiency or even causing it to stop, thus affecting continuous wastewater removal. Therefore, this solution proposes a circulating environmental mechanical bar screen to address the above problems. Summary of the Invention

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] This invention provides, for example Figure 1 - Figure 7 The illustrated circulating environmentally friendly mechanical bar screen cleaner includes: Framework 1; Cleaning component 2 is located inside frame 1. Cleaning component 2 is used to remove impurities from liquid. A power component 4 for driving cleaning component 2 is located on the back of cleaning component 2. The oscillating cam 3 is inserted inside the frame 1. The oscillating cam 3 is used to assist in waste discharge. The back of the oscillating cam 3 is provided with a rotary assembly 5 for driving the oscillating cam 3 to rotate in both directions.

[0025] It should be noted that a frame can be installed on the front and back of the frame 1, and the frame 1 can be fixed in the required position by the frame and bolts. The two ends of the swing roller 3 are respectively inserted and connected to the front and back of the frame 1. Bearing seats are provided at the connection points between the swing roller 3 and the frame 1 at both ends. The position of the swing roller 3 is fixed by the bearing seats without affecting the rotation of the swing roller 3. One side of the swing roller 3 is protruding. When the swing roller 3 rotates, its protruding part can hit the cleaning component 2. In use, the rotary component 5 continuously drives the swing roller 3 to rotate back and forth. The protruding end on the swing roller 3 periodically hits the surface of the cleaning component 2. This hitting action can effectively shake off and peel off various debris attached to the cleaning component 2, thereby avoiding the accumulation of debris on the cleaning component 2 and ensuring that the cleaning component 2 always maintains a good working condition.

[0026] Specifically, a discharge port 101 is provided at the bottom of the frame 1, and a guide plate 102 is inserted and connected inside the frame 1. The guide plate 102 is used to guide the movement of debris, and a feed port 103 is provided on one side of the frame 1.

[0027] It should be noted that in this equipment, the guide plate 102 is a key guiding component. Its core feature is that its horizontal longitudinal section is designed with a unique inverted "V" shape, which creates a natural sloping channel that is high in the center and low on both sides, guiding the movement of debris. The guide plate 102 is firmly fixed at both ends to the front and back inner walls of the frame 1 through welding. This rigid connection method ensures its structural strength and reliability under long-term material impact and vibration. When the equipment is running, the cleaning component 2 pulls various debris stripped from the water upwards. When the debris is moved to the top of the guide plate 102, the material falls off the cleaning component 2. After the falling debris comes into contact with the inclined side wall of the guide plate 102, it will slide naturally and quickly towards the discharge port 101 under the action of gravity, thereby realizing the discharge of debris.

[0028] Specifically, the cleaning component 2 includes a conveyor belt 202 that is inserted inside the frame 1. The outer wall of the conveyor belt 202 is provided with multiple grid bodies 204. The frame 1 is provided with an active roller 201. The conveyor belt 202 is sleeved on the outer wall of the active roller 201. The frame 1 is provided with a first tension roller 203 and a second tension roller 205. The first tension roller 203 and the second tension roller 205 are used to tension the conveyor belt 202. The rotary component 5 is located on the back of the active roller 201.

[0029] It should be noted that the two ends of the drive roller 201, the first tension roller 203, and the second tension roller 205 are respectively inserted and connected to the inner walls of the front and back sides of the frame 1. Bearing seats are provided at the connection points between the ends of the drive roller 201, the first tension roller 203, and the second tension roller 205 and the frame 1. These bearing seats constrain the drive roller 201, the first tension roller 203, and the second tension roller 205 to the frame 1, preventing them from moving while allowing them to rotate. A groove is provided on the side of the conveyor belt 202 away from the grid body 204. Protrusions that match the groove are provided on the outer walls of the drive roller 201, the first tension roller 203, and the second tension roller 205. During use, the protrusions and grooves reinforce the conveyor belt 202. The connection between the drive roller 201, the first tension roller 203, and the second tension roller 205 prevents the drive roller 201 from failing to drive the conveyor belt 202 during use. A water-permeable hole is provided on the grid body 204 for drainage during use. The drive roller 201, the first tension roller 203, and the second tension roller 205 are arranged in a stable triangular layout. Together, they tension and support the conveyor belt 202, creating a triangular area with inclined sides. The core advantage of this structural design is that it naturally forms a stable inclined surface. When subsequent processes require waste removal, materials or waste can smoothly and directionally slide or separate along this inclined surface, avoiding accumulation and jamming. The triangular tensioning structure not only ensures the smooth operation and tension of the conveyor belt 202, but its constructed physical inclined surface also facilitates the waste removal process.

[0030] Furthermore, during use, the power component 4 drives the active roller 201 to rotate, the rotating active roller 201 drives the conveyor belt 202 to move, and the conveyor belt 202 drives the bar screen body 204 to move. The bar screen body 204 picks up the debris in the water and discharges the water from the bar screen body 204 through the holes on the bar screen body 204. In this way, the debris in the water is picked up, thereby achieving the purpose of decontamination.

[0031] Specifically, the power assembly 4 includes a second transmission wheel 404 sleeved on one end of the drive roller 201, a transmission belt 402 is connected to one side of the second transmission wheel 404, a first transmission wheel 403 is connected to the side of the transmission belt 402 away from the second transmission wheel 404, a power motor 401 is fixedly connected to the top of the frame 1, and the first transmission wheel 403 is fixedly connected to the output end of the power motor 401.

[0032] It should be noted that the power motor 401 adopts an existing mature servo motor system. This system integrates three core modules: the motor body, a high-precision encoder, and an intelligent driver. The driver, as the command center, directly receives position, speed, or torque command pulses from the upper controller and precisely drives the motor body accordingly. During installation, the servo motor is firmly fixed to the top of the equipment frame 1 with bolts, ensuring structural rigidity and stability during operation and providing a reliable power source for the entire transmission system. Connected to the output shaft of the power motor 401 is the first transmission wheel 403, whose outer ring is precision machined with a toothed structure. At the same time, the outer wall of the second transmission wheel 404 also has teeth of the same specification. The transmission belt 402 is not an ordinary smooth belt, but has specially meshing teeth on its inner side (i.e., the side near the transmission wheel), thus forming a toothed transmission belt 402. This design completely avoids slippage during the transmission process and achieves synchronous and precise transmission.

[0033] Furthermore, when it is necessary to drive the drive roller 201 to rotate, the power motor 401 is turned on, and the first transmission wheel 403 at its output end is driven to rotate through the power motor 401. The rotating first transmission wheel 403 drives the transmission belt 402 to move, and the transmission belt 402 drives the second transmission wheel 404 to rotate. Finally, the rotating second transmission wheel 404 drives the drive roller 201 to rotate.

[0034] Specifically, the rotary assembly 5 includes a second gear 502 disposed on the back of the oscillating cam roller 3. A toothed plate 506 is meshed at the bottom of the second gear 502. A fixing block 504 is fixedly connected to the back of the frame 1. A guide 6 for limiting the movement direction of the toothed plate 506 is provided at the connection between the toothed plate 506 and the fixing block 504. A driving block 508 is fixedly connected to the back of the toothed plate 506. A sliding groove 503 is provided on the front of the driving block 508. A pushing column 505 for pushing the driving block 508 is inserted inside the sliding groove 503. A first gear 501 is fixedly connected to one end of the pushing column 505. A third gear 509 is meshed on one side of the first gear 501. The third gear 509 is sleeved on the back of the drive roller 201. A mounting frame 507 is fixedly connected to the back of the frame 1. The horizontal longitudinal section of the mounting frame 507 is set in an L shape. The first gear 501 is disposed on the front of the mounting frame 507.

[0035] It should be noted that the mounting frame 507 is firmly connected to the back of the frame 1 through welding, forming a rigid support base. This design ensures that the mounting frame 507 itself will not experience any displacement or vibration during equipment operation, providing a solid and reliable foundation for subsequent rotating components. A fixed shaft is provided on the front of the mounting frame 507, and a ball bearing is fitted on the outer wall of the fixed shaft. The core function of this bearing is to achieve rotational connection. A hole is opened in the middle of the first gear 501, and the ball bearing is inserted into the hole. The first gear 501 and the ball bearing are connected by an interference fit. This connection method fixes the position of the first gear 501 without affecting its rotation. A hole adapted to the drive roller 201 is opened in the middle of the third gear 509, allowing the third gear 509 to be fitted onto the drive roller. At the end of 201, the two are fixed together by welding, so that the drive roller 201 can drive the third gear 509 to rotate; the fixed block 504 is fixedly connected to the back of the frame 1 by welding, and the fixed block 504 is connected to the toothed plate 506 through the guide 6, which restricts the movement direction of the toothed plate 506; the second gear 502 is fixedly connected to the back of the swing cam roller 3 by welding; the push column 505 is fixedly connected to the front of the first gear 501 by welding, so that when the first gear 501 rotates, it drives the push column 505 to make a circular motion; the sliding groove 503 is adapted to the push column 505, so that the push column 505 can be inserted into the sliding groove 503 and slide inside the sliding groove 503.

[0036] Furthermore, the power assembly 4 drives the drive roller 201 to rotate, which in turn drives the third gear 509 to rotate. The third gear 509 then drives the first gear 501 to rotate, which in turn drives the push column 505, which is fixedly connected to it, to perform a circular motion. When the first gear 501 rotates 180 degrees, the moving push column 505 pushes the drive block 508 to move. The moving drive block 508 drives the toothed plate 506 to move to one side, which in turn drives the second gear 502 to rotate. The rotating second gear 502 then drives the oscillating cam... Roller 3 rotates to one side until the protruding end of the oscillating cam 3 hits the conveyor belt 202. When the first gear 501 rotates to 180 to 360 degrees, it drives the push column 505 to move. At this time, the push column 505 pushes the drive block 508 to move in the opposite direction. The moving drive block 508 drives the toothed plate 506 to move in the opposite direction. The moving toothed plate 506 drives the second gear 502 to rotate in the opposite direction. The second gear 502 rotates in the opposite direction and drives the oscillating cam 3 to rotate in the opposite direction until the protruding end of the oscillating cam 3 hits the conveyor belt 202 and then repeats the above steps.

[0037] Specifically, the guide member 6 includes a guide block 602 fixedly connected to the front of the toothed plate 506, and a guide groove 601 is provided on the back of the fixed block 504. The horizontal longitudinal section of both the guide groove 601 and the guide block 602 is convex, and the guide block 602 is inserted into the interior of the guide groove 601.

[0038] It should be noted that both the horizontal longitudinal section of the guide groove 601 and the guide block 602 are set to convex shape. This complementary convex section design allows the guide block 602 to be accurately inserted into and slidably connected inside the guide groove 601. Through the convex design, after the guide block 602 enters the guide groove 601, a stable constraint between the two components is achieved, effectively preventing separation or displacement during movement. Furthermore, the convex contact surface provides smooth guidance and load-bearing, ensuring that the toothed plate 506 performs precise and stable linear movement under the guidance of the fixed block 504, and avoiding wobbling of the toothed plate 506 during movement.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
