Description

Technical Field

[0001] This utility model relates to the field of sludge scraper technology, and in particular to a scraper structure that is easy to disassemble. 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 the collection and removal of sludge from the bottom of circular or rectangular sedimentation tanks. Its core structure consists of a single track (usually arranged along the tank wall or top), a drive unit, a scraper truss, and scrapers. The scraper arm is driven by a motor or hydraulic system to slowly rotate or reciprocate along the track, gradually scraping the sludge deposited at the bottom of the tank to the central sludge hopper or sludge discharge port, and finally discharging it through the sludge discharge pipe.

[0003] The scraper is a crucial component of the sludge scraper. Prolonged use and friction between the scraper and the bottom wall of the sedimentation tank, along with the sludge, can lead to scraper damage, necessitating disassembly and repair or replacement of the entire scraper. However, this method requires disassembling and replacing the entire scraper, resulting in high operating costs. Secondly, friction between the scraper and the bottom wall creates gaps, preventing thorough cleaning of the tank bottom. Furthermore, existing scrapers are of a single, integral structure, limiting their flexibility in assembly and deployment according to specific needs. Their excessive length also hinders initial transportation. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a scraper structure that is easy to disassemble.

Detailed Implementation

[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 structure that is easy to disassemble is disclosed, comprising multiple main boards 1. The bottom surface of the main board 1 is provided with a mounting groove 2. A fixing plate 3 is provided inside the mounting groove 2. The bottom of the fixing plate 3 is provided with a movable cavity 31. A base plate 4 is slidably connected inside the movable cavity 31. Multiple first springs 5 ​​are fixed to the top wall of the movable cavity 31. The bottom ends of the multiple first springs 5 ​​are attached to the upper surface of the base plate 4. Mounting components 7 for mounting the fixing plate 3 are fixed at both ends of the inner sidewall of the mounting groove 2. A splicing component 9 is fixedly connected between two adjacent main boards 1.

[0024] The mounting assembly 7 includes a rod 71 fixed to the inner wall of the mounting groove 2. The top of the fixing plate 3 has a hole 32 for inserting the rod 71. The lower surface of the end of the rod 71 that passes through the hole 32 has a groove 72. The top wall of the groove 72 is fixed with a second spring 73. The bottom end of the second spring 73 is fixedly connected with a locking tooth 74. The bottom end of the locking tooth 74 is engaged with the surface of the fixing plate 3.

[0025] The bottom of the 74 clip, on the side away from the fixing plate 3, has a sloping design.

[0026] In this embodiment, the insertion rod 71 adopts a square structure. When installing the fixing plate 3, the insertion hole 32 on the fixing plate 3 is directly aligned with the insertion rod 71 and inserted. The inclined locking teeth 74 will be squeezed back into the groove 72 first. After the locking teeth 74 completely passes through the insertion hole 32, the second spring 73 squeezes the locking teeth 74, causing the locking teeth 74 to pop out from the groove 72. The locking teeth 74 will then be locked on the surface of the fixing plate 3, thereby fixing the fixing plate 3.

[0027] When it is necessary to remove the fixing plate 3, first squeeze the retaining teeth 74 to retract into the groove 72, and then the fixing plate 3 can be removed from the surface of the insert rod 71.

[0028] A handle 8 is fixed to the surface of the fixing plate 3.

[0029] The handle 8 is designed to make it easy to grip the fixing plate 3 when installing and removing it.

[0030] A guide rod 6 is fixed to the top wall of the movable cavity 31, and a vertical groove 41 is opened on the top of the bottom plate 4. The guide rod 6 is located inside the vertical groove 41 and is slidably connected to the vertical groove 41.

[0031] During use, the first spring 5 presses the bottom plate 4 downwards, ensuring it adheres to the bottom wall of the sedimentation tank and guaranteeing effective sludge scraping. The guide rod 6 and vertical groove 41 provide stable guidance. After the fixing plate 3 is removed from the mounting groove 2, the bottom plate 4 can be directly removed from the movable cavity 31 for replacement.

[0032] The top of motherboard 1 has a curved design.

[0033] Because the water resistance to the main board 1 is very high when the main board 1 moves with the moving mechanism of the sludge scraper, the top of the main board 1 is designed to be curved to guide the water flow upward, thereby reducing the resistance when the main board 1 moves.

[0034] The splicing component 9 includes a horizontal plate 91, on which multiple connecting rods 92 are fixed. Both sides of the main board 1 are provided with connecting holes 10 for the connecting rods 92 to pass through. The surface of the connecting rod 92 away from the horizontal plate 91 is provided with external threads, and an internal thread cap 93 is rotatably connected to the external thread surface. The internal thread cap 93 is in contact with the surface of the main board 1.

[0035] When assembling the two main boards 1, the multiple connecting rods 92 on the horizontal plate 91 are inserted into the connecting holes 10 on the two main boards 1 respectively, and then the internal thread caps 93 are screwed onto the surface of the connecting rods 92 to achieve the splicing of the two main boards 1. In this embodiment, the connecting holes 10 also serve as holes for connecting to the moving mechanism of the sludge scraper.

[0036] Working principle: During assembly, first, two adjacent main plates 1 are spliced ​​together, and then the two adjacent main plates 1 are fixed together by the splicing component 9. After splicing multiple main plates 1, the outermost main plate 1 is connected to the moving structure of the sludge scraper through the connecting hole 10 and bolts. When the sludge scraper moves the scraper structure, the bottom plate 4 fits against the bottom of the sedimentation tank, scraping the sludge to one side. When it is necessary to replace the severely worn bottom plate 4, first remove the fixing plate 3, and then pull the bottom plate 4 out from the movable cavity 31 of the fixing plate 3 and replace it.

[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.
