Description

Technical Field

[0001] This utility model relates to the field of sludge scraper technology, and in particular to a sludge scraper with track cleaning function. Background Technology

[0002] Currently, in the field of wastewater treatment, gantry-type sludge scrapers are commonly used to clean the sludge at the bottom of square sedimentation tanks. This equipment drives traveling wheels to reciprocate along pre-set tracks on both sides of the tank, thereby driving the scraping components to scrape the sludge into the collection hopper. However, these traveling wheels and tracks are typically exposed to the outdoor environment, subject to long-term exposure to and accumulation of dust, fallen debris, leaves, and even rain, snow, and ice. This continuous pollution causes the track working surface to become uneven, and may even create localized obstructions, directly affecting the stable operation of the sludge scraper's traveling wheels.

[0003] Current solutions to this problem primarily rely on regular manual cleaning. However, this method is not only time-consuming and labor-intensive, but also inefficient and poses certain safety risks. If cleaning is not timely or thorough, accumulated dust and impurities on the tracks can easily cause the travel wheels to jam, slip, or even derail. This can range from affecting scraping accuracy and wastewater treatment efficiency to causing overload damage to the drive motor and abnormal wear of the transmission mechanism. Subsequent maintenance is not only technically complex and costly, but also requires downtime, severely hindering the continuous and stable operation of the wastewater treatment plant.

[0004] To address this, we propose a sludge scraper with track cleaning function. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a sludge scraper with track cleaning function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sludge scraper with track cleaning function, comprising two sludge scraper tracks and a sludge scraper truss, wherein two support seats are symmetrically fixedly connected to both sides of the outer surface of the sludge scraper truss, and track wheel assemblies are fixedly connected to the bottom of the four support seats, and the track wheel assemblies are mounted on adjacent sludge scraper tracks.

[0007] A geared motor is fixedly connected to one side of the outer surface of each of the four support bases, and a rotating shaft is fixedly connected to the drive shaft of each of the four geared motors, and the rotating shaft is connected to the adjacent track wheel assembly.

[0008] The outer surfaces of the four rotating shafts are fitted with housings, and the housings are fixedly connected to the support bases. The four housings are respectively installed with the adjacent rotating shafts, and speed-increasing transmission components are installed together.

[0009] A circular shell is fixedly connected to one side of the outer surface of each of the four housings, and a synchronous drive assembly is installed on each of the four circular shells together with the adjacent speed-increasing transmission assembly.

[0010] Each of the four synchronous drive components has two movable ends fixedly connected to an assembly shaft, and the assembly shaft is set through the circular shell. Each of the eight assembly shafts has a roller brush detachably fixedly connected to its bottom.

[0011] Furthermore, each of the four track wheel assemblies includes two first bearing seats, which are fixedly connected to the bottom of the support base. The inner rings of the bearings built into the two first bearing seats are fixedly connected to the track wheel body. The track wheel body is mounted on the scraper track and fixedly connected to the rotating shaft. The double first bearing seat structure provides stable and reliable support for the track wheel and effectively distributes the working load.

[0012] Furthermore, all four speed-increasing transmission components include a large synchronous pulley, which is located inside the housing and fixedly sleeved on the outer surface of the rotating shaft. A small synchronous pulley is provided on one side of the large synchronous pulley. A synchronous belt meshes and sleeves between the large and small synchronous pulleys. The large synchronous pulley drives the small synchronous pulley to rotate through the synchronous belt, thus achieving a speed-increasing effect.

[0013] Furthermore, each of the four synchronous drive components includes a long shaft, which is fixedly connected to a small synchronous pulley. The long shaft extends through the inner wall of the housing into the interior of the circular shell and is rotatably connected to the circular shell. Two first bevel gears are fixedly sleeved on the outer surface of the long shaft, and the two first bevel gears are arranged in a mirror image. Each of the two first bevel gears is meshed with a second bevel gear, and the second bevel gear is fixedly connected to the top of the assembly shaft. The long shaft drives the two first bevel gears to rotate, and the first bevel gears drive the assembly shaft to rotate through the second bevel gears.

[0014] Furthermore, each of the four circular shells has two second bearing seats fixedly connected to its bottom, and the inner ring of the bearing inside the second bearing seat is fixedly sleeved on the outer surface of the assembly shaft. The second bearing seat provides support for the assembly shaft, which facilitates the installation of the assembly shaft.

[0015] Furthermore, all eight assembly shafts are fixedly connected to adjacent roller brushes by multiple bolts. The bolt connection method is simple in structure and easy to install and disassemble, which greatly facilitates the daily maintenance and replacement of roller brushes after wear.

[0016] Furthermore, the two adjacent roller brushes are located on both sides of the adjacent scraper track, which facilitates the cleaning of the scraper track by the roller brushes.

[0017] Furthermore, each of the four geared motors is provided with a shield above it, and the shield is fixedly connected to the support base. The shield provides effective physical protection for the geared motor, a key drive component.

[0018] The beneficial effects of this utility model are:

[0019] In use, this utility model integrates a roller brush driven by the same geared motor and speed-increasing transmission on the sludge scraper truss, which realizes synchronous, automatic and efficient removal of dust and debris on the track while the sludge scraper is moving. This fundamentally solves the problem of low efficiency of manual cleaning, effectively avoids equipment jamming, slippage or even derailment caused by track contamination, and significantly improves the stability, safety and continuity of sewage treatment operations of the sludge scraper.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-4 As shown, a sludge scraper with track cleaning function is disclosed, comprising two scraper tracks 2 and a scraper truss 1. Two support seats 3 are symmetrically fixedly connected to both sides of the outer surface of the scraper truss 1. The support seats 3 are made of Q235B steel plate and welded together, which has sufficient rigidity and strength. They are fixedly connected to the scraper truss 1 by bolts. Track wheel assemblies are fixedly connected to the bottom of each of the four support seats 3, and the track wheel assemblies are mounted on adjacent scraper tracks 2. A reduction motor 5 is fixedly connected to one side of the outer surface of each of the four support seats 3. The drive shafts of the four reduction motors 5 are fixedly connected to a rotating shaft 16, and the rotating shaft 16 is connected to the adjacent track wheel assembly. Each of the four track wheel assemblies includes two first bearing seats 10, and the first bearing seats 10 are fixedly connected to the bottom of the support seats 3. The inner rings of the bearings built into the two first bearing seats 10 are fixedly connected to the track wheel body 9, and the track wheel body 9 is mounted on the scraper track 2 and fixedly connected to the rotating shaft 16.

[0029] Each of the four rotating shafts 16 has a housing 6 fitted onto its outer surface, and the housing 6 is fixedly connected to the support base 3. Each of the four housings 6 and the adjacent rotating shaft 16 is equipped with a speed-increasing transmission assembly. Each of the four speed-increasing transmission assemblies includes a large synchronous pulley 15, which is located inside the housing 6 and fixedly fitted onto the outer surface of the rotating shaft 16. A small synchronous pulley 13 is located on one side of the large synchronous pulley 15. A synchronous belt 14 meshes between the large synchronous pulley 15 and the small synchronous pulley 13. The large synchronous pulley 15 acts as the driving pulley, and the small synchronous pulley 13 acts as the driven pulley. The speed increase is achieved through their diameter ratio, raising the travel speed of the track wheel body 9 to the high speed required by the roller brush 8. The synchronous belt 14 is a rubber synchronous belt (such as HTD). The 8M and 14M models have a fiberglass rope core inside, which features accurate transmission, no slippage, and high efficiency. It is tensioned on two synchronous pulleys, and the preload of the synchronous belt 14 can be adjusted by using a tensioning pulley (existing technology, not shown in the figure).

[0030] Each of the four housings 6 has a circular shell 11 fixedly connected to one side of its outer surface. Each of the four circular shells 11 is equipped with a synchronous drive assembly together with an adjacent speed-increasing transmission assembly. Each of the four synchronous drive assemblies has an assembly shaft 12 fixedly connected to its two movable ends. Each of the four synchronous drive assemblies includes a long shaft 18, which is fixedly connected to a small synchronous pulley 13. The long shaft 18 extends through the inner wall of the housing 6 into the interior of the circular shell 11 and is rotatably connected to the circular shell 11. Two first bevel gears 17 are fixedly sleeved on the outer surface of the long shaft 18, and the two first bevel gears 17 are mirror images of each other. Each of the two first bevel gears 17 is meshed with a second bevel gear 19, and the second bevel gear 19 is fixedly connected to the top of the assembly shaft 12. One end of the long shaft 18 is supported on the side wall of the circular shell 11 by a bearing (such as a deep groove ball bearing).

[0031] Furthermore, the assembly shaft 12 is set through the circular shell 11, and the bottom of each of the four circular shells 11 is fixedly connected to two second bearing seats 7, and the inner ring of the bearing inside the second bearing seat 7 is fixedly sleeved on the outer surface of the assembly shaft 12. The bottom of each of the eight assembly shafts 12 is detachably fixedly connected to a roller brush 8. Each of the eight assembly shafts 12 is fixedly connected to the adjacent roller brush 8 by multiple bolts. The two adjacent roller brushes 8 are located on both sides of the adjacent sludge scraper track 2, and the bristles of the roller brush 8 are usually made of corrosion-resistant and high-toughness nylon material.

[0032] Each of the four geared motors 5 is provided with a shield 4 above it, and the shield 4 is fixedly connected to the support base 3. The shield 4 is made of Q235A cold-rolled steel plate and is installed above the geared motor 5 to protect the motor from external environmental damage such as rain, sun exposure, and falling debris, thereby extending the service life of the motor.

[0033] In this application, all four geared motors 5 are controlled by the electrical control box used by the sludge scraper.

[0034] Working principle: When the sludge scraper needs to move along the sludge scraper track 2 to perform sludge scraping operations, the reduction motor 5 fixed on the support base 3 is activated. The output power of the reduction motor 5 drives the rotating shaft 16 to rotate, and the rotating shaft 16 directly drives the track wheel body 9 to rotate, thereby driving the entire sludge scraper to move on the sludge scraper track 2. This is the basic walking function of the sludge scraper.

[0035] To achieve cleaning, a large synchronous pulley 15 is fixedly mounted on the drive shaft 16. Through the transmission of the synchronous belt 14, the large synchronous pulley 15 transmits power to the smaller synchronous pulley 13. Based on the belt drive principle, this structure forms a speed-increasing mechanism, allowing the smaller synchronous pulley 13 and its connected long shaft 18 to achieve a higher rotational speed than the track wheel body 9. The high-speed rotating long shaft 18 extends into the cylindrical shell 11, driving two fixed first bevel gears 17 to rotate. The first bevel gears 17 drive the meshing second bevel gear 19 to rotate, thereby driving the assembly shaft 12 to rotate. A roller brush 8 is detachably mounted to the bottom end of each assembly shaft 12 via bolts. When the assembly shaft 12 rotates at high speed under the drive of the second bevel gear 19, it drives the roller brush 8 to rotate as well.

[0036] Two adjacent roller brushes 8 are arranged on both sides of the scraper track 2. As the scraper moves forward, these high-speed rotating roller brushes 8 can effectively clean the dust, debris, ice and snow on the top and inner sides of the scraper track 2.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
