Description

Technical Field

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

[0002] A monorail sludge scraper is a sludge cleaning device used in sedimentation tanks of wastewater treatment plants. It is mainly used for scraping and removing sludge from the bottom of circular or rectangular sedimentation tanks. Its core structure consists of a single rail (usually arranged along the tank wall or top), a drive unit, a scraping truss, and scrapers. The scraper arm is driven by a motor or hydraulic system to slowly rotate or reciprocate along the rail, gradually scraping the sludge deposited at the bottom of the tank to the central sludge hopper or sludge discharge port, and finally discharged through the sludge discharge pipe.

[0003] A search revealed that patent CN220513493U discloses a scraper device for a monorail sludge scraper. The device has transmission cavities on both sides inside the mounting block. When a worn scraper needs to be replaced, simply insert an Allen wrench into the Allen block and rotate it. This will drive the double-threaded transmission rod to move the two moving blocks in opposite directions, thereby releasing the clamping block from holding the scraper and allowing the scraper to be easily pulled out for replacement. However, the device still has the following drawbacks: Since the mounting block needs to be fixed to the moving mechanism of the sludge scraper with bolts, after the mounting block is fixed, the scraper is in close contact with the bottom wall of the sedimentation tank. If the scraper needs to be replaced, the scraper cannot be directly removed from the bottom of the mounting block due to the obstruction of the bottom wall of the sedimentation tank. Therefore, the mounting block needs to be disassembled before the scraper can be removed. Thus, the disassembly and installation of the scraper is still not convenient. Secondly, since there is no support on the side of the mounting block away from the moving mechanism, after the scraper wears down and gaps appear between it and the bottom of the tank during long-term use, the weight of the entire scraper and the mounting block acts on the connection between the mounting block and the moving mechanism, which can easily cause the bolts to loosen. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a scraper device for a single-rail sludge scraper.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a scraper device for a single-rail sludge scraper, comprising a housing, wherein the sides and bottom of the housing are open, a plate is fitted to the inner wall of the housing, a cover plate is fitted to the surface of the plate, a snap-fit ​​assembly is provided on both sides of the cover plate, and snap holes for snapping into the snap-fit ​​assembly are provided on both sides of the housing, a support assembly is fixed to one end of the outer wall of the housing, and an mounting plate is fixed to the side of the housing away from the support assembly.

[0022] 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.

[0023] like Figures 1-4 As shown, a scraper device for a monorail sludge scraper is disclosed, comprising a housing 1, with open sides and bottom. A plate 2 is attached to the inner wall of the housing 1, and a cover plate 3 is attached to the surface of the plate 2. Both sides of the cover plate 3 are provided with snap-fit ​​components 6. Both sides of the housing 1 are provided with snap-fit ​​holes 8 for snapping into the snap-fit ​​components 6. A support component 9 is fixed to one end of the outer wall of the housing 1, and an mounting plate 10 is fixed to the side of the housing 1 away from the support component 9.

[0024] The mounting plate 10 has multiple mounting holes.

[0025] In this embodiment, the mounting holes on the mounting plate 10 match the holes on the sludge scraper's moving mechanism. The mounting plate 10 is fixed by bolts inserted into the mounting holes and the holes on the moving mechanism. The sludge scraper's moving mechanism can then drive the scraper device to move. Furthermore, after installation, the bottom of the plate 2 is in contact with the bottom of the sedimentation tank.

[0026] The support assembly 9 includes a horizontal plate 91 fixed to the surface of the housing 1, and a vertical tube 92 fixed to the lower surface of the horizontal plate 91. A slide rod 93 is slidably connected inside the vertical tube 92, and a wheel frame 95 is fixed to the bottom end of the slide rod 93. A roller 96 is rotatably connected inside the wheel frame 95. A second spring 94 is fixedly connected to the top of the slide rod 93 and the inner top wall of the vertical tube 92.

[0027] In this embodiment, a rubber sealing ring is provided on the surface of the slide rod 93. When the slide rod 93 slides along the vertical pipe 92, it can prevent sewage from entering the interior of the vertical pipe 92. The second spring 94 plays a buffering role in the support assembly 9. When the device moves with the moving mechanism of the sludge scraper and encounters a higher position, the second spring 94 can be compressed when the roller 96 passes over the position, thereby ensuring that the roller 96 can pass smoothly.

[0028] Multiple positioning rods 4 are fixed on the inner wall of the housing 1, and multiple positioning holes 5 for inserting the positioning rods 4 are opened on the top of the plate 2 and the cover plate 3.

[0029] When fixing plate 2 and cover plate 3, the positioning hole 5 needs to be aligned with the positioning rod 4 and inserted into the housing 1 to ensure that plate 2 and cover plate 3 are installed accurately.

[0030] The snap-fit ​​assembly 6 includes a groove 61 formed on the side of the cover plate 3. A first spring 62 is fixed to the inner wall of the groove 61, and a snap-fit ​​rod 63 is fixedly connected to the other end of the first spring 62. The end of the snap-fit ​​rod 63 away from the first spring 62 is snapped into the snap-fit ​​hole 8.

[0031] In this embodiment, both the locking rod 63 and the locking hole 8 are square structures. Under the extrusion force of the first spring 62, after the locking rod 63 is inserted into the locking hole 8, the cover plate 3 is fixed inside the housing 1. At this time, the cover plate 3 presses and fixes the plate 2 inside the housing 1.

[0032] A slotted opening 65 is provided on the side of the groove 61 away from the plate 2. A lever 64 is fixed on the side of the lever 63 near the slotted opening 65. The lever 64 extends through the slotted opening 65 to the surface of the cover plate 3, and the lever 64 is slidably connected to the slotted opening 65.

[0033] When it is necessary to remove the cover plate 3, the lever 64 is pulled to move the locking lever 63 inside the groove 61, so that the locking lever 63 disengages from the locking hole 8, and the cover plate 3 can be removed from the housing 1. After removing the cover plate 3, the plate body 2 can be removed.

[0034] A handle 7 is fixed to the surface of the cover plate 3 near the slot 65. When the lever 64 is pulled, the handle 7 can be gripped to easily remove the cover plate 3.

[0035] Working principle: In use, the mounting plate 10 is fixedly connected to the sludge scraper moving mechanism. When the sludge scraper moves the device, the plate 2 scrapes the sludge at the bottom of the sedimentation tank. When the plate 2 needs to be replaced due to severe wear, first pull the lever 64 to separate it from the locking hole 8, then take the cover plate 3 out of the housing 1, then take out the plate 2, replace it with a new plate 2 and put it into the housing 1, then put the cover plate 3 into the housing 1. After releasing the lever 64, under the compression of the first spring 62, the locking lever 63 is locked into the locking hole 8, thus fixing the cover plate 3 and achieving the fixed installation of the plate 2.

[0036] 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.
