Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a single-rail sludge scraper. Background Technology

[0002] A sludge scraper is a machine used to remove sludge from riverbeds. It is used in large-diameter circular sedimentation tanks in urban sewage treatment plants, waterworks, and industrial wastewater treatment plants to remove sludge settled at the bottom of the tank and skim off scum from the surface.

[0003] Patent application CN212881189U discloses a single-rail sludge scraper, relating to the field of cleaning devices, aiming to solve the problem of large amounts of sludge accumulating on the bottom wall of existing filter tanks after long-term use, which affects normal operation if not cleaned in time. It includes a hollow, open-topped tank for cleaning, with a scraper installed inside. Multiple sets of fixing rings are connected to the scraper, and a fixing shaft passes through each fixing ring. A limiting block passes through the middle of the fixing shaft, and a transmission device is connected to the fixing shaft. A rectangular through-slot is provided in the tank along the direction of movement of the transmission device, and a drive source is located on the left side of the tank. This invention increases the rotational power of the sludge scraper through the cooperation of the transmission device and the motor, making the sludge scraper more efficient.

[0004] However, since sludge scrapers are usually large in size and the belts are relatively long, the belts are prone to wear and loosening during long-term use. At the same time, using only the second pulley as a connecting part makes the scraper unstable during movement. To address these issues, we have introduced a single-rail sludge scraper. Utility Model Content

[0005] This utility model discloses a single-rail sludge scraper, which improves upon the existing structure and its shortcomings to provide a single-rail sludge scraper with better practical value.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A single-rail sludge scraper includes a cleaning tank, a mounting plate slidably connected to the top of the cleaning tank, a mounting head fixedly connected to one side of the mounting plate, a mounting block fixedly connected to one side of the mounting head, a synchronous pulley rotatably connected inside the mounting head, a synchronous belt provided on the outer side of the synchronous pulley, a mounting base fixedly connected to one side of the cleaning tank, a drive motor provided on one side of the mounting base, one end of the output shaft of the drive motor fixedly connected to one side of one of the synchronous pulleys, a scraper provided inside the cleaning tank, a connecting assembly provided on the top of the scraper, and a clamping assembly provided on one side of the cleaning tank.

[0008] The connecting assembly includes a movable plate that is slidably connected to the top of the mounting plate. A mounting rod is fixedly connected to one side of the movable plate. Fixed rings are fixedly connected at equal intervals to the top of the scraper. The outer side of the mounting rod is fixedly connected to the inside of the fixed rings. A limit rod is fixedly connected to one side of the mounting head. The outer side of the limit rod is slidably connected to the inside of the movable plate.

[0009] In a preferred embodiment, the top of the movable plate is fixedly connected with fixed rods at equal intervals, the top of the fixed rods extends to the top of the timing belt and is slidably connected to a connecting plate, and the outer side of the fixed rods is threaded with a nut, the bottom of the nut abutting against the top of the connecting plate.

[0010] In a preferred embodiment, one end of the mounting rod is rotatably connected to a roller, and a groove is formed on one side of the inner wall of the cleaning pool, with the bottom of the roller contacting the bottom of the inner wall of the groove.

[0011] In a preferred embodiment, the clamping assembly includes a fixing plate fixedly connected to one side of the cleaning tank. The fixing plate has two threaded rods internally threadedly connected to it. The top of each of the two threaded rods is rotatably connected to a fixing block. A shaft is fixedly connected to one side of the fixing block. A clamping wheel is rotatably connected to the outside of the shaft. The top of the clamping wheel abuts against the bottom of the timing belt.

[0012] In a preferred embodiment, the scraper tilt angle is between 3° and 15°.

[0013] The monorail sludge scraper provided by this utility model has the following advantages:

[0014] Firstly, by inserting the fixing rod on the movable plate into the through hole of the timing belt and securing it with a connecting plate and nut, a firm connection between the timing belt and the movable plate is ensured. This design makes the movable plate more stable during movement, reducing the problem of uneven scraper movement caused by belt slippage or slack.

[0015] Secondly, when the timing belt slips, the tension can be effectively increased by using the threaded rod, fixing block, shaft, and tensioning wheel in the clamping assembly. The tensioning wheel clamps the timing belt from the bottom, ensuring that the timing belt maintains appropriate tension during operation, thereby reducing slippage and improving transmission stability.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] The single-rail sludge scraper disclosed in this utility model is mainly used in cleaning equipment scenarios.

[0023] Reference Figures 1 to 4 A single-rail sludge scraper includes: a cleaning tank 1, a mounting plate 2 slidably connected to the top of the cleaning tank 1, a mounting head 3 fixedly connected to one side of the mounting plate 2, a mounting block 4 fixedly connected to one side of the mounting head 3, a synchronous wheel 5 rotatably connected inside the mounting head 3, a synchronous belt 6 provided on the outer side of the synchronous wheel 5, a mounting base 7 fixedly connected to one side of the cleaning tank 1, a drive motor 8 provided on one side of the mounting base 7, one end of the output shaft of the drive motor 8 fixedly connected to one side of one of the synchronous wheels 5, a scraper 9 provided inside the cleaning tank 1, a connecting component provided on the top of the scraper 9, and a clamping component provided on one side of the cleaning tank 1;

[0024] The connecting assembly includes a movable plate 10, which is slidably connected to the top of the mounting plate 2. A mounting rod 11 is fixedly connected to one side of the movable plate 10. A fixing ring 12 is fixedly connected to the top of the scraper 9 at equal intervals. The outer side of the mounting rod 11 is fixedly connected to the inside of the fixing ring 12. A limiting rod 13 is fixedly connected to one side of the mounting head 3. The outer side of the limiting rod 13 is slidably connected to the inside of the movable plate 10.

[0025] Fixed rods 15 are fixedly connected at equal intervals to the top of the movable plate 10. The top of the fixed rods 15 extends to the top of the synchronous belt 6 and is slidably connected to the connecting plate 14. Nuts 16 are threadedly connected to the outside of the fixed rods 15. The bottom of the nuts 16 abuts against the top of the connecting plate 14.

[0026] One end of the mounting rod 11 is rotatably connected to a roller 17, and a groove 18 is provided on one side of the inner wall of the cleaning pool 1, with the bottom of the roller 17 in contact with the bottom of the inner wall of the groove 18.

[0027] The clamping assembly includes a fixing plate 19, which is fixedly connected to one side of the cleaning tank 1. The fixing plate 19 has two threaded rods 20 internally threaded. The top of each threaded rod 20 is rotatably connected to a fixing block 21. A shaft 22 is fixedly connected to one side of the fixing block 21. A clamping wheel 23 is rotatably connected to the outside of the shaft 22. The top of the clamping wheel 23 abuts against the bottom of the timing belt 6.

[0028] In the above technical solution, considering that sludge scrapers are usually large in size and the belts are relatively long, the belts are prone to wear and loosening during long-term use. Additionally, using only the second pulley as a connecting component results in insufficient stability of the scraper during movement. To address these issues, the specific operation is as follows: By setting up a connecting assembly, the fixing rod 15 on the movable plate 10 is inserted into the corresponding through hole on the synchronous belt 6. Then, the connecting plate 14 is fitted onto it and fixed with the nut 16, clamping a section of the synchronous belt 6 between the movable plate 10 and the connecting plate. In step 14, the drive motor 8 is activated, driving the synchronous pulley 5 and synchronous belt 6 to rotate. This causes the movable plate 10 to move along a trajectory between the bottom of the mounting plate 2 and the outside of the limiting rod 13, driving the roller 17 to move inside the groove 18. This, in turn, drives the scraper 9 to clean the bottom of the cleaning pool 1. When the synchronous belt 6 slips, the clamping assembly is used to rotate the two sets of threaded rods 20 in sequence, driving the fixed block 21, shaft 22, and clamping wheel 23 to move upwards. The clamping wheel 23 then clamps the synchronous belt 6 from the bottom, increasing the tension of the synchronous belt 6 and reducing slippage. The robust connecting assembly improves the stability of the scraper 9 during movement, enhancing the sludge scraping effect. The tensioning function of the clamping assembly extends the service life of the synchronous belt 6, reduces belt wear and loosening, and lowers the frequency of belt replacement.

[0029] Reference Figures 1 to 4In a preferred embodiment, the scraper 9 is tilted at an angle between 3° and 15°;

[0030] Working principle: In use, the fixing rod 15 on the movable plate 10 is inserted into the corresponding through hole on the synchronous belt 6, and then the connecting plate 14 is put on it and fixed by the nut 16. A section of the synchronous belt 6 is clamped between the movable plate 10 and the connecting plate 14. The drive motor 8 is started to drive the synchronous wheel 5 and the synchronous belt 6 to rotate, so that the movable plate 10 moves along a trajectory between the bottom of the mounting plate 2 and the outside of the limit rod 13, and drives the roller 17 to move inside the groove 18, thereby driving the scraper 9 to clean the bottom of the cleaning pool 1. When the synchronous belt 6 slips, the two sets of threaded rods 20 are rotated in sequence using the clamping assembly, which drives the fixing block 21, the shaft 22 and the clamping wheel 23 to move upward. The clamping wheel 23 clamps from the bottom of the synchronous belt 6, increasing the tension of the synchronous belt 6 and reducing slippage.
