Description

Technical Field

[0001] The utility model relates to the technical field of solid waste treatment, in particular to a novel dust cover structure for a vibration screen. Background Art

[0002] Solid waste treatment is a process of reducing its volume and accelerating its natural purification through physical means (such as crushing, compression, drying, evaporation, incineration, etc.) or biochemical effects (such as oxidation, digestion, decomposition, absorption, etc.) and chemical effects such as pyrolysis and gasification. In the solid waste treatment process, a vibrating screen can be used to screen the solid waste. The vibrating screen works by using the reciprocating vibration generated by the vibrator excitation. The vibrating screen can screen the solid waste according to its volume for subsequent treatment. The vibrating screen is composed of a dust cover, a screen frame, a screen, a mesh frame, a screen cleaning device, a motor (vibration source), a shock absorbing spring, a base, etc., so the dust cover is an important part of the vibrating screen.

At the same time, an annular flexible corrugated ring for sealing is connected between the vibration screen 703 and the mounting frame 6 to prevent solid waste materials from falling through the gap between the vibration screen 703 and the mounting frame 6.

[0026] like Figure 2 and Figure 4 As shown, the screening auxiliary component 5 includes a motor 501, a rotating shaft 502, a telescopic rod 503, a toggle plate 504 and an extension plate 505.
