Description

Technical Field

[0001] The utility model belongs to the technical field of mud scrapers, and more specifically relates to a mud scraper scraper chain link structure, a mud scraper scraper chain and a mud scraper. Background Art

[0002] Non-metallic chain scraper is a kind of scraping equipment, which can be used for surface skimming and bottom scraping operations in rectangular primary and secondary sedimentation tanks. It is mainly composed of driving device, scraper, working chain link, scraper chain link, upper and lower wear-resistant shoes, main shaft, guide sprocket seat and other parts.

[0003] The non-metal chain scraper adopts a double-row chain traction form. The traction chain of the equipment is equipped with a scraper chain link every 3 meters. The scraper chain link is fixed to the scraper, and the whole is formed into a ring through the chain link. The scraper contacts the guide rail set at the bottom of the pool and moves slowly, scraping the sludge at the bottom of the pool into the sludge tank at the end of the pool, and at the same time scraping the scum and floating oil on the surface of the pool into the scum tank, creating conditions for mud and slag discharge.

[0004] The traction chain of the non-metallic chain scraper is the main force-bearing component of the whole machine, including working chain links, scraper chain links, chain pins, snap rings, etc. (such as Figure 1 As shown in the figure, the main material is made of high-strength engineering plastics, which has the advantages of high strength, corrosion resistance, aging resistance, and light weight. It is responsible for transmitting the driving force output by the driving device to each scraper, driving the scraper to scrape the sludge at the bottom of the pool into the sludge bucket.

[0005] The scraper link structure in the existing scraper traction chain is an integrated structure. In addition to installing the scraper, the scraper link also serves as a working link. It is the main load-bearing part of the entire traction chain and the component with the most concentrated stress. Like the fiberglass scraper, it is the component with the highest incidence of overload or fatigue damage in the entire machine. Therefore, when a scraper / scraper link has a problem, it needs to be replaced, which means that the entire chain needs to be disassembled and disconnected, which is time-consuming and labor-intensive and delays the operation of the entire system.

[0038] Specifically, the scraper 5 is fixed on any working link 1 of the chain by extending the pin shaft 2 and the connecting plate 3, so that when the scraper 5 is damaged and needs to be replaced, the scraper 5 can be separated from the connecting plate 3, and the scraper 5 can be replaced by separating the connecting plate 3 and the extended pin shaft 2. Compared with the existing scraper 5 connection, there is no need to disassemble the chain, and it does not affect the use of the entire chain. The maintenance and replacement of the scraper 5 is simpler and more convenient, and the time for replacing the scraper 5 is reduced.

[0039] Furthermore, the working chain link 1 of the scraper blade chain link structure is not provided, and can be connected with a common pin shaft, or can be used with an extended pin shaft 2 in conjunction with a shaft sleeve.

[0040] In this embodiment, the connecting plate 3 includes a T-shaped plate, two connecting holes are arranged at intervals on the horizontal part of the lower end of the T-shaped plate, one side of the vertical part of the upper end of the T-shaped plate is provided with an inclined tie bar, and the other side of the vertical part is connected to the scraper 5 through an extended pad frame 4.

[0041] Specifically, the support for the scraper 5 is ensured by lengthening the cushion frame 4, so as to prevent the middle part of the scraper 5 from being suspended and deformed.

[0042] In this embodiment, an annular clamping groove is provided on the connecting section, and a clamping ring is detachably connected in the clamping groove, and the clamping ring is used to prevent the connecting plate 3 from falling off.

[0043] Specifically, the connecting plate 3 is restricted by the clamping ring to prevent the connecting plate 3 from falling off from the connecting section.
