[0002] In wastewater treatment and industrial sludge treatment, scrapers are commonly used mechanical equipment. Their scraper assembly, as a core component, directly affects the scraping effect and the equipment's lifespan. Traditional scraper assemblies often use metal materials, such as steel. However, metal materials are prone to corrosion under long-term contact with corrosive media such as sludge and wastewater, leading to problems such as chain breakage and scraper damage. This not only results in high maintenance costs but also affects the normal operating efficiency of the scraper. Furthermore, the friction between the metal scraper and the sludge is relatively high, leading to high energy consumption during operation and less than ideal scraping results. In addition, the structural design of traditional scraper assemblies makes installation and disassembly cumbersome, hindering later maintenance and replacement.

[0003] Therefore, there is an urgent need for a new type of non-metallic chain scraper scraper device to solve the above-mentioned problems in the existing technology. Utility Model Content

Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-4A scraper device for a non-metallic chain scraper includes a non-metallic chain 1, a scraper body 2, and a connecting assembly. Both the non-metallic chain 1 and the scraper body 2 are made of high-polymer composite material.

The fixing seat 3 has coaxially arranged mounting holes 6 on both sides. The scraper body 2 is provided with connecting ears 7, which are placed inside the fixing seat 3. The adjusting bolt 4 passes through the mounting holes 6 and the connecting ears 7 and is connected to the fixing seat 3 using the locking nut 5.

[0024] In this embodiment: the fixed base 3 is installed on the non-metallic chain 1, and the adjusting bolt 4 passes through the mounting hole 6 and the connecting lug 7 on the scraper body 2. A locking nut 5 is used to connect it to the fixed base 3, achieving a detachable connection between the scraper body 2 and the non-metallic chain 1. This facilitates the installation, disassembly, and adjustment of the scraper body 2, and makes subsequent maintenance and replacement easier. The wear-resistant strip 8 is set on the bottom surface of the scraper body 2, effectively reducing friction between the scraper body 2 and the sludge, improving the wear resistance of the scraper body 2, and further extending its service life. Both the non-metallic chain 1 and the scraper body 2 are made of high-polymer composite materials. High-polymer composite materials have excellent corrosion resistance, effectively resisting the erosion of sludge, sewage, and other media, extending the service life of the scraper device. Simultaneously, high-polymer composite materials are lightweight, reducing equipment operating energy consumption compared to metal materials. This provides a basic frame for the scraper device, giving it corrosion resistance and ease of disassembly and maintenance.

[0025] When the non-metallic chain 1 scraper is working, the power unit drives the non-metallic chain 1 to move. Since the scraper body 2 is detachably connected to the non-metallic chain 1 through the connecting component, the scraper body 2 moves synchronously with the non-metallic chain 1. During the movement, the wear-resistant strips 8 on the bottom surface of the scraper body 2 come into contact with the sludge and scrape it off. At the same time, the guide grooves 10 on the working surface of the scraper body 2 guide the sludge flow, so that the sludge is scraped off more smoothly and the scraping efficiency is improved. The links of the non-metallic chain 1 are connected by ceramic pins 9 to ensure the stability and reliability of the chain during the movement.

[0026] As a technical optimization of this utility model, the polymer composite material is a glass fiber reinforced nylon composite material, and the mass percentage of glass fiber in the composite material is 30%-50%.

[0027] In this embodiment, the polymer composite material is a glass fiber reinforced nylon composite material. By controlling the mass percentage of glass fiber, the polymer composite material is guaranteed to have good mechanical strength, wear resistance and corrosion resistance, which further improves the performance and service life of the scraper device.

[0028] As a technical optimization of this utility model, the wear-resistant strip 8 is detachably connected to the lower part of the scraper body 2 through a dovetail groove structure, and the wear-resistant strip 8 is made of ultra-high molecular weight polyethylene or ceramic composite material.

[0029] In this embodiment, the wear-resistant strip 8 and the scraper body 2 are detachably connected by a dovetail groove structure, which facilitates the replacement of the wear-resistant strip 8. The wear-resistant strip 8 made of ultra-high molecular weight polyethylene or ceramic composite material has excellent wear resistance, which can effectively protect the scraper body 2 and extend the service life of the scraper device.

[0030] As a technical optimization of this utility model, the links of the non-metallic chain 1 are connected by pins 9, which are made of ceramic material.

[0037] In this embodiment: the elastic retaining ring 12 has an elastic structure that can automatically compensate for the gap caused by wear and maintain connection stability. The preload of the elastic retaining ring 12 can prevent the adjusting bolt 4 from being accidentally loosened due to vibration, and completely avoid the risk of loosening and falling off the locking nut 5, and prevent foreign objects from entering.
