Description

Technical Field

[0001] The utility model relates to the field of sludge scraper conveyors, in particular to a sealed sludge scraper conveyor structure. Background Art

[0002] Scraper conveyor is a kind of transportation equipment that continuously conveys bulk materials with the help of moving scraper chains in a closed rectangular cross-section shell. It is mainly used to convey block, granular or powdered materials such as clay, coal powder, flour cement, sludge, etc. It is suitable for mining, metallurgy, light industry, boiler, environmental protection and other industries. Scraper conveyor has the characteristics of reasonable design, simple structure, long service life, good sealing, and large angle lifting of materials (0-90 degrees). The scraper conveyor designed this time is mainly for conveying dehydrated sludge with 80% water content, conveying plate and frame mud cake with 60% water content, and conveying sludge after drying.

[0003] 1. There is a hollow space between the moving part of the tail tensioning sprocket assembly and the frame, which means it cannot be completely sealed, resulting in leakage of internal sewage and sludge, and a poor on-site environment. 2. Since the chain tension and conveying load force of the corner scraper box are concentrated here, the corners are worn, resulting in premature damage, a very high failure rate, and it is not easy to repair. 3. For the straight-section scraper box, when the straight section is lifted at a large angle, the falling sludge is easily brought back to the feed port, resulting in a decrease in efficiency. 4. For the head scraper box, the scraper does not unload the sludge sufficiently, causing the scraper to bring the sludge back to the feed port. Utility Model Content

Through the coordinated use of the head scraper box 4, the driving sprocket 41, the second sprocket 42, the third sprocket 43, the motor 45 and the R series reducer 46, in order to ensure that the sludge falls smoothly from above the mud outlet, the scraper is in a vertical downward state at the discharge port 12.

[0042] Specifically, the working principle and operation method of the utility model are as follows:

[0043] Step 1: Mesh the chain scraper assembly with the first sprocket 14, the corner sprocket 21, the driving sprocket 41, the second sprocket 42 and the third sprocket 43, then synchronously connect the driving sprocket 41 with the R series reducer 46 through the chain and the sprocket, start the motor 45, the motor 45 drives the driving sprocket 41 to rotate through the R series reducer 46, and the driving sprocket 41 drives the first sprocket 14, the corner sprocket 21, the second sprocket 42 and the third sprocket 43 to rotate synchronously through the chain tube plate assembly.

The chain tube plate drives the sludge to rotate together, and the chain circulates and rotates between the upper support plate 113, the lower support plate 114 and the auxiliary plate 115 to prevent the chain from deflecting;

[0044] Step 2: When moving into the corner scraper box 2, the corner sprocket 21 can reduce the load on the chain and the upper support plate 113 and the lower support plate 114, thereby increasing the service life of the upper support plate 113 and the lower support plate 114. The coordinated use of the arc auxiliary plate 22 and the corner auxiliary plate 23 can prevent the chain from deviating in the corner scraper box 2. The observation window 24 can observe the operating status in the box, and the second inspection plate 112 can facilitate the maintenance of the corner scraper box 2.

[0045] Step three, when moving into the straight scraper box 3, since the straight scraper box 3 is conveyed and lifted at a large angle and is not in a vertical state, the sludge that falls when the sludge rises will be lifted again, and the fourth inspection plate 31 can be removed to facilitate maintenance of the straight scraper box 3.

[0046] Step 4, when moving into the head scraper box 4, since the driving sprocket 41, the second sprocket 42 and the third sprocket 43 form an inverted triangle, the scraper is vertically downward when moving to the top, and the sludge on the scraper falls from the discharge port 12 by gravity, so that the sludge on the scraper can be unloaded more cleanly.
